WHITESTONE REIT ANNOUNCES OPERATING RESULTS FOR THE THIRD QUARTER 2012

• Acquired three Arizona Community Centered Properties^TM below replacement cost for an aggregate purchase price of $82.2 million

• Raised net proceeds of approximately $59.0 million in August 2012 common share offering

• Total Operating Portfolio Occupancy grew 1% to 87% as of September 30, 2012 as compared to September 30, 2011

• Total revenues increased 32% to $11.6 million for third quarter of 2012 as compared to the same period in 2011

• Property net operating income for the 3rd quarter increased 35% to $7.0 million as compared to the same period in 2011

Houston, Texas, November 7, 2012 - Whitestone REIT (NYSE: WSR - “Whitestone” or the “Company”), a fully integrated real estate company that owns, operates and re-develops Community Centered Properties^TM, which are visibly located in established or developing culturally diverse neighborhoods, announced its financial results for the third quarter of 2012.

“Our quarterly results reflect the work we have done to increase and strengthen our revenues and our overall enterprise value. We have improved our underlying property asset values through increasing occupancy, redeveloping and repositioning properties, and acquiring accretive Community Centered Properties,” stated James C. Mastandrea, Whitestone's Chairman and Chief Executive Officer. “In the third quarter we drove operating portfolio occupancy to 87%, which marked our fifth consecutive quarter of improving occupancy. These improvements resulted in the year-over-year increases in our overall financial results. Our Community Centered Property approach concentrates primarily on small service based tenants who meet community needs by providing medical, educational, casual dining and convenience services. This strategy has proven to be quite effective and results in premium rents for our smaller spaces. With $82 million in properties added in Arizona in the third quarter, we now own over one million square feet of leasable space in community centers in the Phoenix, Arizona market. Our pipeline of acquisition opportunities continues to be focused on properties in foreclosure, in loan default, and under stress. While our targeted acquisition approach may result in fluctuations in acquisitions activity quarter-to-quarter from a timing perspective, we expect the overall result of acquiring assets below replacement cost to add value on an annual basis and over the long-term.”

Highlights: Third Quarter 2012 Compared to Third Quarter 2011

• Net income attributable to Whitestone REIT was $163,000, or $0.01 per diluted common share, compared to $578,000, or $0.05 per diluted common share.

• Funds from Operations ("FFO") increased approximately 32% to $2.9 million, or $0.20 per diluted common share and operating partnership unit ("OP unit"), as compared to $2.2 million, or $0.17 per diluted common share and OP unit.

• Funds from Operations-Core ("FFO-Core") increased 39% to $3.2 million, or $0.22 per diluted common share and OP unit, as compared to $2.3 million, or $0.18 per diluted common share and OP unit.

• Property net operating income (“NOI”) increased 35% to $7.0 million as compared to $5.2 million. The increase of $1.8 million is primarily attributable to NOI of new acquisitions.

• Whitestone raised approximately $59.0 million in net proceeds through the sale of 4.8 million common shares in August 2012, including the over-allotment option exercise.

Acquisition Activity

During the third quarter Whitestone completed acquisitions of three Community Centered Properties^TM in the Phoenix area and one adjacent land parcel for an aggregate of $82.2 million in three off-market transactions, all at prices below replacement cost. They include:

• Village Square at Dana Park was purchased for approximately $46.5 million. The 310,979 square foot center was 71% leased at the time of purchase and is located in the Mesa submarket of Phoenix, Arizona. In the same

transaction, the Company also acquired several development parcels totaling 4.7 acres for approximately $4.0 million.

• Fountain Square was acquired for approximately $15.4 million. The 118,209 square foot property was 76% leased at the time of purchase and is located in Scottsdale, Arizona.

• Paradise Plaza was purchased in August 2012 for approximately $16.3 million. Paradise Plaza was 100% occupied at the time of purchase with 125,898 of square feet of gross leasable area, and is located in the Paradise Valley area of Scottsdale, Arizona.

Third Quarter 2012 Leasing Highlights

Operating Portfolio Occupancy increased to 87% as of September 30, 2012 as compared to 86% as of September 30, 2011. The Company defines Operating Portfolio Occupancy as physical occupancy in all properties, excluding (i) new acquisitions through the earlier of attainment of 90% occupancy or 18 months of ownership and (ii) properties that are undergoing significant redevelopment or re-tenanting.

The Company's total occupancy increased 1% to 85% as of September 30, 2012 as compared to 84% at September 30, 2011. Total occupancy includes community centers under redevelopment, recent acquisitions and community centers undergoing significant re-tenanting.

Whitestone focuses primarily on smaller space, service-oriented entrepreneurial tenants in multi-cultural neighborhoods, which drives premium rents. A summary of leasing activity is shown below:

• A 23% increase in total number of tenants to 1,051 from 850 for the same period of 2011;

• 63 new and renewal leases signed in the third quarter of 2012 versus 67 in the same period of 2011; and

• New and renewal leases signed during the third quarter of 2012 represent a total of 144,000 square feet and an average size of 2,300 square feet as compared to a total of 152,000 square feet and an average size of 2,300 square feet in the same period of 2011.

Community Centered Properties^TM Portfolio Statistics

As of September 30, 2012, Whitestone owned 50 Community Centered Properties^TM with approximately 4.2 million square feet of gross leasable area, including three development land parcels, located in five of the top markets in the United States in terms of population growth: Houston, Dallas, San Antonio, Phoenix and Chicago.

The Company's strategic efforts target entrepreneurial, service-oriented tenants that cater to neighborhoods within three to five miles from each Community Centered Property^TM. These tenants tend to occupy smaller spaces (less than 3,000 square feet) and, as of September 30, 2012, provided a 52% premium rental rate compared to the Company's larger space tenants. Whitestone currently services 1,051 tenants throughout its portfolio.  No single tenant accounted for more than 1.2% of the Company's annualized base rental revenues as of September 30, 2012. The tenant base mix is diversified to Drive Traffic and Drive Value^TM with service offerings concentrated in medical, educational, casual dining and convenience services.

Balance Sheet

Whitestone owned 23 properties unencumbered by debt as of the end of the third quarter of 2012 with an undepreciated cost basis of $187 million. The total undepreciated values of the Company's real estate assets and real estate indebtedness were $389 million and $168 million, respectively, as of September 30, 2012. As of September 30, 2012, 59% of the Company's outstanding debt was subject to fixed interest rates which limit the risk of fluctuating interest rates. The Company's weighted average interest rate on all debt as of the end of the quarter was 4.7%.

 Whitestone, as of September 30, 2012, had $80 million available on its three-year $125 million unsecured revolving credit facility.

Dividend

Whitestone declared a quarterly cash dividend of $0.285 per common share and OP unit, paid or payable in three equal installments of $0.095 in October, November and December 2012. Based on the closing price on November 6, 2012 of $13.22 per share, the dividend represents an annual yield of approximately 8.6%.

Non-GAAP Financial Measures

This release contains the supplemental financial measures that are not calculated pursuant to U.S. generally accepted accounting principles ("GAAP") including FFO, FFO-Core, NOI and EBITDA. Following are explantions and reconciliations of these metrics to their most comparable GAAP metric.

FFO: Management believes that FFO is a useful measure of the Company's operating performance. The Company computes FFO as defined by the National Association of Real Estate Investment Trusts, or NAREIT, which states that FFO should represent net income (loss) available to common shareholders (computed in accordance with GAAP) excluding gains or losses from sales of operating assets and extraordinary items, plus depreciation and amortization of operating properties, including the Company's share of unconsolidated real estate joint ventures and partnerships. In October 2011, NAREIT communicated to its members that the exclusion of impairment writedowns of depreciable real estate is consistent with the definition of FFO, and prior periods should be restated to be consistent with this guidance. As the Company has not had any impairments in the past five years, the Company was not required to restate our FFO for prior periods. FFO does not represent cash flows from operating activities determined in accordance with GAAP and should not be considered an alternative to net income as an indication of the Company's performance or to cash flow from operations as a measure of liquidity or ability to make distributions.

Management considers FFO a useful additional measure of performance for an equity REIT because it facilitates an understanding of the operating performance of its properties without giving effect to real estate depreciation and amortization, which assumes that the value of real estate assets diminishes predictably over time. Since real estate values have historically risen or fallen with market conditions, management believes that FFO provides a more meaningful and accurate indication of the Company's performance and useful information for the investment community to compare Whitestone to other REITs since FFO is generally recognized as the industry standard for reporting the operations of REITs.

Other REITs may use different methodologies for calculating FFO, and accordingly, the Company's FFO may not be comparable to other REITs. The Company presents FFO per diluted share calculations that are based on the outstanding dilutive common shares plus the outstanding OP units for the periods presented.

FFO-Core: Management believes that the computation of FFO in accordance with NAREIT's definition includes certain items that are not indicative of the results provided by the Company's operating portfolio and affect the comparability of the Company's period-over-period performance. These items include, but are not limited to, legal settlements, legal and professional fees, gains and losses on insurance claim settlements and acquisition costs. Therefore, in addition to FFO, management uses FFO-Core, which the Company defines to exclude such items. Management believes that these adjustments are appropriate in determining FFO-Core as they are not indicative of the operating performance of the Company's assets. In addition, the Company believes that FFO-Core is a useful supplemental measure for the investing community to use in comparing the Company to other REITs as many REITs provide some form of adjusted or modified FFO.

NOI: Management believes that NOI is a useful measure of the Company's property operating performance. The Company defines NOI as operating revenues (rental and other revenues) less property and related expenses (property operation and maintenance and real estate taxes). Because NOI excludes general and administrative expenses, depreciation and amortization, involuntary conversion, interest expense, interest income, provision for income taxes and gain or loss on sale or disposition of assets, it provides a performance measure that, when compared year over year, reflects the revenues and expenses directly associated with owning and operating commercial real estate properties and the impact to operations from trends in occupancy rates, rental rates and operating costs, providing perspective not immediately apparent from net income. The Company uses NOI to evaluate its operating performance since NOI allows the Company to evaluate the impact that factors, such as occupancy levels, lease structure, lease rates and tenant base, have on the Company's results, margins and returns. In addition, management believes that NOI provides useful information to the investment community about the Company's property and operating performance when compared to other REITs since NOI is generally recognized as a standard measure of property performance in the real estate industry. However, NOI should not be viewed as a measure of the Company's overall financial performance since it does not reflect general and

administrative expenses, depreciation and amortization, involuntary conversion, interest expense, interest income, provision for income taxes, gain or loss on sale or disposition of assets, and the level of capital expenditures and leasing costs necessary to maintain the operating performance of the Company's properties. Other REITs may use different methodologies for calculating NOI, and accordingly, the Company's NOI may not be comparable to other REITs.

EBITDA: Management believes that EBITDA is an appropriate supplemental measure of operating performance to net income attributable to the Company. The Company defines EBITDA as operating revenues (rental and other revenues) less property and related expenses (property operation and maintenance and real estate taxes) and general and administrative expenses. Management believes that EBITDA provides useful information to the investment community about the Company's operating performance when compared to other REITs since EBITDA is generally recognized as a standard measure. However, EBITDA should not be viewed as a measure of the Company's overall financial performance since it does not reflect depreciation and amortization, involuntary conversion, interest expense, provision for income taxes, gain or loss on sale or disposition of assets, and the level of capital expenditures and leasing costs necessary to maintain the operating performance of the Company's properties. Other REITs may use different methodologies for calculating EBITDA, and accordingly, the Company's EBITDA may not be comparable to other REITs.
