Statement Regarding Forward-Looking Statements

This supplemental package contains forward-looking statements within the meaning of the federal securities laws, including information related to run rate net operating income. Such statements are based on management’s beliefs and assumptions made based on information currently available to management. Such statements are subject to risks, uncertainties and assumptions and are not guarantees of future performance and may be affected by known and unknown risks, trends, uncertainties and factors that are beyond our control. Should one or more of these risks or uncertainties materialize, or should underlying assumptions prove incorrect, actual results may vary materially from those anticipated, estimated or projected. Some of the risks and uncertainties that may cause our actual results, performance or achievements to differ materially from those expressed or implied by forward-looking statements include, among others, the following:

• adverse economic or real estate developments in our markets or the technology industry;

• inability to successfully develop and lease new properties and space held for redevelopment;

• our failure to obtain necessary outside financing;

• our dependence upon significant tenants;

• bankruptcy or insolvency of a major tenant;

• downturn of local economic conditions in our geographic markets;

• our inability to comply with the rules and regulations applicable to public companies;

• our ability to manage our growth effectively;

• difficulty acquiring or operating properties in foreign jurisdictions;

• defaults on or non-renewal of leases by tenants;

• increased interest rates and operating costs;

• restrictions on our ability to engage in certain business activities;

• risks related to joint venture investments;

• decreased rental rates or increased vacancy rates;

• difficulties in identifying properties to acquire and completing acquisitions;

• increased competition or available supply of data center space;

• our failure to successfully operate acquired properties;

• our inability to acquire off-market properties;

• delays or unexpected costs in development or redevelopment of properties;

• our failure to maintain our status as a REIT;

• possible adverse changes to tax laws;

• environmental uncertainties and risks related to natural disasters;

• financial market fluctuations;

• changes in foreign currency exchange rates;

• changes in foreign laws and regulations, including those related to taxation and real estate ownership and operation; and

• changes in real estate and zoning laws and increases in real property tax rates.

The risks included here are not exhaustive, and additional factors could adversely affect our business and financial performance. We discussed a number of additional material risks in our annual report on Form 10-K for the year ended December 31, 2007, our quarterly report on Form 10-Q for the quarter ended March 31, 2008 and other filings with the Securities and Exchange Commission. Those risks continue to be relevant to our performance and financial condition. Moreover, we operate in a very competitive and rapidly changing environment. New risk factors emerge from time to time and it is not possible for management to predict all such risk factors, nor can it assess the impact of all such risk factors on the business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements. We expressly disclaim any responsibility to update forward-looking statements, whether as a result of new information, future events or otherwise.

(1) The market value of common equity is based on the closing stock price at the end of the quarter and assumes 100% redemption of the limited partnership units in the operating partnership, including vested and unvested long-term incentive units, for shares of our common stock. Excludes shares issuable with respect to stock options that have been granted but have not yet been exercised, and also excludes shares issuable upon the redemption of Class C units which have not yet vested and shares of our common stock issuable upon redemption thereof.

(2) Excludes operations for properties sold in 2007: 100 Technology Center Drive (March 2007) and 4055 Valley View Lane (March 2007), for all periods presented.

(3) EBITDA is calculated as earnings before interest, taxes, depreciation and amortization. For a discussion of EBITDA, see page 27. For a reconciliation of net income available to common stockholders to EBITDA, see page 10.

(4) Adjusted EBITDA is EBITDA adjusted for preferred dividends and minority interests. For a discussion of Adjusted EBITDA, see page 27. For a reconciliation of net income available to common stockholders to Adjusted EBITDA, see page 10.

(5) Cash interest expense is interest expense per our statement of operations (including interest expense on discontinued operations) adjusted for noncash interest expense and includes capitalized interest. For a reconciliation of GAAP interest expense to cash interest expense see page 10.

(6) Fixed charges consist of cash interest expense, scheduled debt principal payments and preferred dividends.

(7) Debt service coverage ratio is Adjusted EBITDA divided by cash interest expense. Ignoring the effect of the gain on sale for 100 Technology Center Drive and 4055 Valley View Lane, debt service coverage ratio was 3.1x for the three months ended March 31, 2007.

(8) Fixed charge coverage ratio is Adjusted EBITDA divided by fixed charges. Ignoring the effect of the gain on sale for 100 Technology Center Drive and 4055 Valley View Lane, fixed charge coverage ratio was 2.4x for the three months ended March 31, 2007.

(9) For a definition and discussion of FFO see page 27. For a reconciliation of net income available to common stockholders to FFO, see page 9.

(10) For a definition and discussion of AFFO, see page 27. For a reconciliation of FFO to AFFO, see page 9.

(11) Diluted FFO payout ratio is dividend declared per common share and unit divided by diluted FFO per share and unit.

(12) Diluted AFFO payout ratio is dividend declared per common share and unit divided by diluted AFFO per share and unit.

(13) Portfolio statistics exclude operations for properties sold in 2007: 100 Technology Center Drive (March 2007) and 4055 Valley View Lane (March 2007), for all periods presented.

(14) Includes 100% of the square feet from properties owned by two consolidated joint ventures, of which we own a 50% interest.

(15) Redevelopment space requires significant capital investment in order to develop data center facilities that are ready for use. Most often this is shell space. However, in certain circumstances this may include partially built datacenter space that was not completed by previous ownership and requires a large capital investment in order to build out the space.

(16) Occupancy and same store occupancy excludes space held for redevelopment.

(17) Average remaining lease term excludes renewal options, weighted by net rentable square feet.

(18) Same store properties were acquired before December 31, 2006. Same store occupancy statistics exclude properties sold in 2007: 100 Technology Center Drive (March 2007) and 4055 Valley View Lane (March 2007), for all periods presented.

(a) Cash interest expense is interest expense less amortized deferred financing fees and includes interest that we capitalized. We consider cash interest expense to be a useful measure of interest as it excludes non-cash based interest expense.

(b) For a definition of Fixed Charges see page 6, footnote 6.

(c) Adjusted EBITDA divided by interest expense. Ignoring the effect of the gain on sale of 100 Technology Center Drive and 4055 Valley View Lane, debt service coverage ratio was 3.2x using GAAP interest expense and 3.1x using cash interest expense for the three months ended March 31, 2007.

(d) Adjusted EBITDA divided by fixed charges. Fixed charges include interest expense as per (a) above and scheduled debt principal payments and preferred dividends. Ignoring the effect of the gain on sale of 100 Technology Center Drive and 4055 Valley View Lane, fixed charges coverage ratio was 2.5x using GAAP interest expense and 2.4x using cash interest expense for the three months ended March 31, 2007.

(e) Mortgage debt and other loans divided by mortgage debt and other loans plus the liquidation value of preferred stock and the market value of outstanding common stock and operating partnership units, assuming the redemption of operating partnership units for shares of our common stock.

(f) Same as (e), except numerator includes preferred stock.

(g) Calculated as income including gain on sale of assets before minority interest and interest divided by GAAP interest expense. Ignoring the effect of the gain on sale of 100 Technology Center Drive and 4055 Valley View Lane, pretax income to interest expense was 1.5x for the three months ended March 31, 2007.

Management Statements on Non-GAAP Supplemental Measures

Funds from Operations:

We calculate Funds from Operations, or FFO, in accordance with the standards established by the National Association of Real Estate Investment Trusts, or NAREIT. FFO represents net income (loss) (computed in accordance with GAAP), excluding gains (or losses) from sales of property, real estate related depreciation and amortization (excluding amortization of deferred financing costs) and after adjustments for unconsolidated partnerships and joint ventures. Management uses FFO as a supplemental performance measure because, in excluding real estate related depreciation and amortization and gains and losses from property dispositions, it provides a performance measure that, when compared year over year, captures trends in occupancy rates, rental rates and operating costs. We also believe that, as a widely recognized measure of the performance of REITs, FFO will be used by investors as a basis to compare our operating performance with that of other REITs. However, because FFO excludes depreciation and amortization and captures neither the changes in the value of our properties that result from use or market conditions, nor the level of capital expenditures and leasing commissions necessary to maintain the operating performance of our properties, all of which have real economic effect and could materially impact our results from operations, the utility of FFO as a measure of our performance is limited. Other REITs may not calculate FFO in accordance with the NAREIT definition and, accordingly, our FFO may not be comparable to such other REITs’ FFO. Accordingly, FFO should be considered only as a supplement to net income as a measure of our performance. FFO for all periods presented in this supplemental information includes the results of properties sold in 2007: 100 Technology Center Drive (March 2007) and 4055 Valley View Lane (March 2007).

Adjusted Funds From Operations:

We present adjusted funds from operations, or AFFO, as a supplemental operating measure because, when compared year over year, it assesses our ability to fund dividend and distribution requirements from our operating activities. We also believe that, as a widely recognized measure of the operations of REITs, AFFO will be used by investors as a basis to assess our ability to fund dividend payments in comparison to other REITs, including on a per share and unit basis. We calculate adjusted funds from operations, or AFFO, by adding to or subtracting from FFO (i) non-real estate depreciation, (ii) amortization of deferred financing costs (iii) noncash compensation (iv) straight line rents (v) fair value of lease revenue amortization (vi) capitalized leasing payroll (vii) recurring tenant improvements and (viii) capitalized leasing commissions. Other equity REITs may not calculate AFFO in a consistent manner. Accordingly, our AFFO may not be comparable to other equity REITs’ AFFO. AFFO should be considered only as a supplement to net income computed in accordance with GAAP as a measure of our performance. AFFO for all periods presented in this supplemental information includes the results of properties sold in 2007: 100 Technology Center Drive (March 2007) and 4055 Valley View Lane (March 2007).

EBITDA and Adjusted EBITDA:

We believe that earnings before interest expense, income taxes, depreciation and amortization, or EBITDA and Adjusted EBITDA (as defined below), are useful supplemental performance measures because they allow investors to view our performance without the impact of noncash depreciation and amortization or the cost of debt and with respect to Adjusted EBITDA preferred dividends and minority interests. Adjusted EBITDA is EBITDA excluding minority interests and preferred stock dividends. In addition, we believe EBITDA and adjusted EBITDA are frequently used by securities analysts, investors and other interested parties in the evaluation of REITs. Because EBITDA and adjusted EBITDA are calculated before recurring cash charges including interest expense and income taxes, and are not adjusted for capital expenditures or other recurring cash requirements of our business, their utility as a measure of our performance is limited. Accordingly, EBITDA and Adjusted EBITDA should be considered only as supplements to net income (computed in accordance with GAAP) as a measure of our financial performance. Other equity REITs may calculate EBITDA and Adjusted EBITDA differently than we do; accordingly, our EBITDA and Adjusted EBITDA may not comparable to such other REITs’ EBITDA and Adjusted EBITDA. EBITDA and Adjusted EBITDA for all periods presented in this supplemental information includes the results of properties sold in 2007: 100 Technology Center Drive (March 2007) and 4055 Valley View Lane (March 2007).

NOI and Run-rate NOI:

Net Operating Income (NOI)

NOI represents rental revenue and tenant reimbursement revenue less rental property operating and maintenance, property taxes and insurance expenses (as reflected in statement of operations). NOI is commonly used by stockholders, company management and industry analysts as a measurement of operating performance of the company’s rental portfolio. However, because NOI excludes depreciation and amortization and captures neither the changes in the value of our properties that result from use or market conditions, nor the level of capital expenditures and leasing commissions necessary to maintain the operating performance of our properties, all of which have real economic effect and could materially impact our results from operations, the utility of NOI as a measure of our performance is limited. Other REITs may not calculate NOI in the same manner we do and, accordingly, our NOI may not be comparable to such other REITs’ NOI. Accordingly, NOI should be considered only as a supplement to net income as a measure of our performance.

Run-rate NOI:

Run-rate NOI represents NOI as defined above adjusted for new acquisitions to show an estimate of NOI as if the property had been owned for the entire quarter. Run-rate NOI is commonly used by stockholders, company management and industry analysts as a measurement of future operating performance of the company’s rental portfolio. Run-rate NOI may not be indicative of future performance. Actual performance is subject to risks, uncertainties and assumptions. See the discussion of forward-looking statements on page 3.
