| ● | acquire R&D, office and industrial properties identified by the Berg Group in California, Oregon and Washington, subject to approval of the Independent Directors Committee of the board of directors. |

|--------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| ·   | focusing on general purpose, single-tenant Silicon Valley R&D properties for technology companies in order to maintain low operating costs, reduce tenant turnover and capitalize on our relationships with these companies and our extensive knowledge of their real estate needs; and |
|--------------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| ·   | maintaining prudent financial management principles that emphasize current cash flow while building long-term value, the acquisition of pre-leased properties to reduce development and leasing risks and the maintenance of sufficient liquidity to acquire and finance properties on desirable terms. |
|--------------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| ·   | External Development Affiliate. Although the Berg land holdings option agreement expired on December 31, 2010, we anticipate that our relationship with the Berg Group will continue to help us achieve our objectives of long-term sustainable growth as well as maximization of long-term stockholder value. We will still have access to one of the most experienced development teams in the Silicon Valley without the expense of maintaining development personnel. In addition, with the Berg Group’s extensive experience and strong relationship in the Silicon Valley real estate industry, we believe we are well-positioned to take advantage of attractive acquisition and development opportunities. The relationship with the Berg Group helps us maintain and develop long-term relationships with a diverse tenant base and manage operating expenses, capital improvements and tenant improvements through the efficient use of our internal management and leasing function. |

| ·   | Lean Organization, Experienced Team.  In part because of our primary focus on Silicon Valley, our experience with the special real estate requirements of information technology tenants and the long-term triple-net structure of our leases, we are able to conduct and expand our business with a small management team comprised of highly qualified and experienced professionals working within a relatively flat organizational structure. We believe that the leanness of our organization and our experience will enable us to rapidly assess and respond to market opportunities and tenant needs, control operating expenses and develop and maintain excellent relationships with tenants. We further believe that these advantages translate into significantly lower costs for operations and give us the ability, along with the Berg Group, to compete favorably with other R&D property developers in Silicon Valley, especially for build-to-suit projects subject to competitive bidding. Furthermore, we believe this lower cost structure allows us to generate better returns from properties whose value can be increased through appropriate remodeling and efficient property management. |

| ·   | Sound Property Management Practices.  For each property, the management team, along with the Berg Group staff, develops a specific marketing and property management program. We select vendors and subcontractors on a competitive bid basis from a select group of highly qualified firms with whom we maintain ongoing relationships and carefully supervise their work. |

| (3)   | As of December 31, 2010, 2009, 2008, 2007 and 2006, total properties include a property at 245 Caspian in Sunnyvale with no building. In 2001, we paid the Berg Group approximately $7.5 million for their commitment to complete an approximate 75,000 to 90,000 square foot building on the property. |
|-----------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| (4)   | Average monthly rental income per square foot has been determined by taking the total cash base rent for the period divided by the number of months in the period, and then divided by the average occupied square feet in the period. |
|-----------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| (5)   | Funds from Operations (“FFO”) is a non-GAAP financial term used by REITs to measure and compare operating performance. As defined by the National Association of Real Estate Investment Trusts (“NAREIT”), FFO represents net income (loss) (computed in accordance with GAAP), including non-recurring events other than “extraordinary items” under GAAP and excluding gains and losses from sales of discontinued operations or depreciable operating properties, plus real estate related depreciation and amortization (excluding amortization of deferred financing costs and depreciation of non-real estate assets) and after adjustments for unconsolidated partnerships and joint ventures. FFO does include impairment losses for properties held for sale and held for use. Additionally, our 2010, 2009, 2008, 2007 and 2006 FFO calculation includes our portion of the depreciation and amortization of real estate from our unconsolidated joint venture, but excludes the above-market lease intangible asset, which was recorded as a reduction of revenues. Management considers FFO to be an appropriate supplemental measure of our operating and financial performance because when compared year over year, it reflects the impact to operations from trends in occupancy rates, rental rates, operating costs, general and administrative expenses and interest costs, providing a perspective not immediately apparent from net income. In addition, management believes that FFO provides useful information about our financial performance when compared to other REITs because FFO is generally recognized as the industry standard for reporting the operations of REITs. FFO should neither be considered as an alternative for neither net income as a measure of profitability nor is it comparable to cash flows provided by operating activities determined in accordance with GAAP. FFO is not comparable to similarly entitled items reported by other REITs that do not define them exactly as we define FFO. |
