Company Profile

June 30, 2010

The Company

Alexandria Real Estate Equities, Inc. (the “Company” or “Alexandria”), a self-administered and self-managed real estate investment trust (“REIT”), is the largest owner and preeminent REIT focused principally on science-driven cluster formation. Our operating platform is based on the principle of “clustering” with assets and operations located in key life science markets. The Company has significant real estate assets adjacent to key life science entities which we believe results in higher occupancy levels, longer lease terms, higher rental income, and higher returns.  These locations are in the best submarkets in each of the top life science cluster destinations, including San Francisco and San Diego, California, Eastern Massachusetts, New Jersey and Suburban Philadelphia, New York City, Southeast, Suburban Washington, D.C., Seattle, Washington, and international locations. Client tenants include institutional (universities and independent not-for-profit institutions), pharmaceutical, biotechnology, medical device, product, service, and translational entities, as well as government agencies.  The Company was founded in 1994 by Jerry M. Sudarsky and Joel S. Marcus and the Company executed its initial public offering in 1997.  Alexandria is the leading life science real estate company and is known for its very well located high-quality environmentally sustainable real estate, technical infrastructure, and unique expertise it provides to its broad and diverse high quality life science industry client tenant base.

Management

Alexandria’s executive and senior management team is highly experienced in the REIT industry (with both real estate and life science experience and expertise) and is the most accomplished team focused on providing high-quality environmentally sustainable real estate, technical infrastructure, and unique expertise to the broad and diverse life science industry. Our deep and talented team has decades of real estate and life science industry experience. We believe that our expertise, experience, reputation, and key life science relationships provide Alexandria significant competitive advantages in attracting new business opportunities. Our management team also includes highly experienced regional market directors each averaging over 20 years of real estate experience and over 10 years with Alexandria. Our regional market directors have tremendous experience and valuable relationships that enable Alexandria to develop long-term relationships with preeminent life science entities.

Strategy

Alexandria’s primary business objective is to maximize shareholder value by providing its shareholders and employees with the greatest possible total return. The key elements to our strategy include our consistent focus on the top life science cluster destinations with our properties located adjacent to life science entities driving growth and technological advances within each cluster. These adjacency locations are characterized by high barriers to entry and exit, limited supply of available space, and represent highly desirable locations for tenancy by life science entities. Alexandria’s strategy also includes leveraging on its deep and broad life science and real estate relationships in order to attract new and leading life science client tenants and value-added real estate opportunities through acquisitions, redevelopment, and development.

Financial Results

For the second quarter of 2010, we reported funds from operations (“FFO”) attributable to Alexandria Real Estate Equities, Inc.’s common stockholders of $9,840,000, or $0.22 per share (diluted), compared to FFO attributable to Alexandria Real Estate Equities, Inc.’s common stockholders of $68,401,000, or $1.59 per share (diluted), for the second quarter of 2009.  For the six months ended June 30, 2010, we reported FFO attributable to Alexandria Real Estate Equities, Inc.’s common stockholders of $59,703,000, or $1.35 per share (diluted), compared to FFO attributable to Alexandria Real Estate Equities, Inc.’s common stockholders of $129,764,000, or $3.43 per share (diluted), for the six months ended June 30, 2009.  In the second quarter of 2010, we recognized a loss on early extinguishment of debt of approximately $41.5 million upon completion of our exchange of approximately $232.7 million principal amount of our 8% unsecured convertible notes for common stock and cash (“Exchange Offer”).  FFO attributable to Alexandria Real Estate Equities, Inc.’s common stockholders for the three and six months ended June 30, 2010 excluding the loss on early extinguishment of debt was $54,563,000, or $1.10 per share (diluted), and $108,547,000, or $2.18 per share (diluted), respectively.  In the second quarter of 2009, we recognized a gain on early extinguishment of debt of approximately $11.3 million related to the repurchase, in privately negotiated transactions, of approximately $75 million (par value) of our 3.70% unsecured convertible notes.  Additionally, during the second quarter of 2009, we recognized income of approximately $7.2 million for a cash payment related to real estate acquired in November 2007.  In the first quarter of 2009, we recognized additional rental income of approximately $18.5 million related to a modification of a lease for a property in South San Francisco, California.  The weighted average number of common stock outstanding for calculating FFO per share (diluted) attributable to Alexandria Real Estate Equities, Inc.’s common stockholders totaled 44,904,999 and 43,071,925 for the second quarter of 2010 and 2009, respectively, and 44,384,570 and 37,810,869 for the six months ended June 30, 2010 and 2009, respectively.

Financial Results (continued)

The following table summarizes the significant items noted above that impacted FFO (diluted) (in thousands):

(1)                    Due to the $41.5 million loss on early extinguishment of debt, our FFO results for the three and six months ended June 30, 2010 do not assume conversion of our 8% unsecured convertible notes for FFO per share (diluted) purposes as the impact to FFO per share was antidilutive to each period pursuant to the if-converted method of accounting.  Excluding the loss on early extinguishment of debt, the impact of the assumed conversion of our 8% unsecured convertible notes would have been dilutive and the interest related to the notes is added to FFO (diluted).  For all periods since issuance of the notes in April 2009, except the three and six months ended June 30, 2010, there is no add back for the assumed conversion of our 8% unsecured convertible notes since FFO attributable to Alexandria Real Estate Equities, Inc.’s common stockholders – numerator for FFO per share (diluted), as reported, already included amounts related to the assumed conversion of our 8% unsecured convertible notes pursuant to the if-converted method of accounting.

The following table summarizes the significant items noted above that impacted total revenues (in thousands):

FFO is a non-GAAP measure widely used by publicly traded real estate investment trusts.  We compute FFO in accordance with standards established by the Board of Governors of the National Association of Real Estate Investment Trusts (“NAREIT”) in its April 2002 White Paper and related implementation guidance.  A reconciliation of net income attributable to Alexandria Real Estate Equities, Inc.’s common stockholders in accordance with United States generally accepted accounting principles (“GAAP”) to FFO attributable to Alexandria Real Estate Equities, Inc.’s common stockholders is included in the financial information accompanying this press release.  The primary reconciling item between GAAP net income attributable to Alexandria Real Estate Equities, Inc.’s common stockholders and FFO attributable to Alexandria Real Estate Equities, Inc.’s common stockholders is depreciation and amortization expense. Depreciation and amortization expense for the three months ended June 30, 2010 and 2009 was $30,342,000 and $29,722,000, respectively.  Depreciation and amortization expense for the six months ended June 30, 2010 and 2009 was $60,080,000 and $61,168,000, respectively.  Net loss attributable to Alexandria Real Estate Equities, Inc.’s common stockholders for the second

quarter of 2010 was $20,393,000, or $0.45 per share (diluted), compared to net income attributable to Alexandria Real Estate Equities, Inc.’s common stockholders of $35,498,000, or $0.82 per share (diluted), for the second quarter of 2009.  Net income attributable to Alexandria Real Estate Equities, Inc.’s common stockholders for the six months ended June 30, 2010 was $206,000, compared to net income attributable to Alexandria Real Estate Equities, Inc.’s common stockholders of $68,287,000, or $1.81 per share (diluted), for the six months ended June 30, 2009.

Leasing Activity

For the second quarter of 2010, we executed a total of 35 leases for approximately 551,000 rentable square feet at 26 different properties (excluding month-to-month leases).  Of this total, approximately 416,000 rentable square feet related to new or renewal leases of previously leased space (renewed/released space) and approximately 135,000 rentable square feet related to developed, redeveloped or previously vacant space.  Of the 135,000 rentable square feet, approximately 53,000 rentable square feet were related to our development or redevelopment programs, with the remaining approximately 82,000 rentable square feet related to previously vacant space.  Rental rates for these new or renewal leases (renewed/released space) were on average approximately 5.1% higher on a GAAP basis than rental rates for expiring leases.

For the six months ended June 30, 2010, we executed a total of 75 leases for approximately 1,031,000 rentable square feet at 48 different properties (excluding month-to-month leases).  Of this total, approximately 681,000 rentable square feet related to new or renewal leases of previously leased space and approximately 350,000 rentable square feet related to developed, redeveloped or previously vacant space.  Of the 350,000 rentable square feet, approximately 189,000 rentable square feet were related to our development or redevelopment programs, with the remaining approximately 161,000 rentable square feet related to previously vacant space.  Rental rates for these new or renewal leases were on average approximately 4.2% higher on a GAAP basis than rental rates for expiring leases.

As of June 30, 2010, approximately 89% of our leases (on a rentable square footage basis) were triple net leases, requiring tenants to pay substantially all real estate taxes, insurance, common area and other operating expenses, including increases thereto.  In addition, approximately 8% of our leases (on a rentable square footage basis) required the tenants to pay a majority of operating expenses.  Additionally, approximately 92% of our leases (on a rentable square footage basis) provided for the recapture of certain capital expenditures, and approximately 94% of our leases (on a rentable square footage basis) contained effective annual rent escalations that were either fixed or indexed based on the consumer price index or another index.

Exchange of 8% Unsecured Convertible Notes

Our 8% unsecured convertible notes are convertible under certain circumstances at a conversion rate of approximately 24.1546 shares of common stock per $1,000 in bonds, representing a conversion price of approximately $41.40 per share of our common stock, or approximately 5.8 million shares of our common stock in total for the entire $240 million principal amount of notes originally issued.  We apply the if-converted method for purposes of determining the impact of our 8% unsecured convertible notes on earnings per share (diluted) and FFO per share (diluted). In applying the if-converted method, we assume that our 8% unsecured convertible notes are converted for purposes of calculating earnings per share (diluted) or FFO per share (diluted) if the effect of such conversion is dilutive to earnings per share or FFO per share, as the case may be. If the effect of the assumed conversion is dilutive, earnings per share (diluted) or FFO per share (diluted) is calculated by adding back interest charges applicable to our 8% unsecured convertible notes to the numerator and our 8% unsecured convertible notes are assumed to have been converted at the beginning of the period presented (or at the date of issuance, if occurring on a date later than the beginning of the period presented) and the resulting incremental shares associated with the assumed conversion are included in the denominator. Furthermore, we assume that our 8% unsecured convertible notes are converted for the period prior to any retirement or actual conversion if the effect of such assumed conversion would be dilutive, and any shares of common stock issued upon retirement or conversion are included in the denominator for the period after the date of retirement or conversion. Since issuance, and for periods through the first quarter of 2010, we had assumed conversion of our 8% unsecured convertible notes for purposes of calculating FFO per share (diluted) as the impact to FFO per share was dilutive for each period pursuant to the if-converted method of accounting.  As a result, for all periods presented through March 31, 2010, the underlying shares of our common stock of approximately 5.8 million shares were included in our weighted average shares of common stock outstanding for FFO per share (diluted).

Second Quarter Ended June 30, 2010 Financial and Operating Results

Exchange of 8% Unsecured Convertible Notes (continued)

In June 2010, we completed the Exchange Offer.  The terms of the Exchange Offer included 24.1546 shares of our common stock, plus a cash premium of $180 per $1,000 in bonds.  As the Exchange Offer terms provided for an equivalent number of shares of our common stock, per bond, as compared to the existing bondholder conversion option, we anticipated that the Exchange Offer would not by itself impact our total weighted average shares of common stock outstanding for purposes of calculating FFO per share (diluted), assuming that our 8% unsecured convertible notes are dilutive to FFO per share (dilutive) for such periods.

Upon completion of the Exchange Offer, we retired $232.7 million principal amount of our 8% unsecured convertible notes (representing approximately 97% of the $240 million aggregate principal of our 8% unsecured convertible notes outstanding prior to the Exchange Offer) in exchange for approximately 5.6 million shares of our common stock (representing approximately 97% of the underlying 5.8 million shares of our common stock) and cash payments of approximately $41.9 million.  In connection with the Exchange Offer, we recognized a loss on early extinguishment of debt of approximately $41.5 million in the second quarter of 2010.   Due to the $41.5 million loss on early extinguishment of debt, our FFO results for the three and six months ended June 30, 2010 do not assume conversion of our 8% unsecured convertible notes for FFO per share (diluted) purposes as the impact to FFO per share was antidilutive to each period pursuant to the if-converted method of accounting.  Excluding the loss on early extinguishment of debt, our weighted average shares of common stock outstanding for calculating FFO per share (diluted) for the three and six months ended June 30, 2010 would have included approximately 4.8 million and 5.3 million additional shares.  We anticipate the assumed conversion of our 8% unsecured convertible notes to be dilutive pursuant to the if-converted method of accounting for the year ended December 31, 2010, such that the total weighted average shares of common stock outstanding for purposes of calculating FFO per share (diluted) includes the weighted average shares of common stock actually issued upon completion of the Exchange Offer and the weighted average shares of common stock outstanding assuming conversion of such outstanding 8% unsecured convertible notes for each period before and after the Exchange Offer.

In July 2010, we repurchased, in a privately negotiated transaction, an additional $7.1 million principal amount of our 8% unsecured convertible notes for an aggregate cash price of approximately $12.8 million.  We expect to record a loss on early extinguishment of debt related to the repurchase in the third quarter of 2010 of approximately $1.3 million.

The following table presents a reconciliation for the three and six months ended June 30, 2010 from FFO (diluted), as reported, to FFO (diluted) excluding the loss on early extinguishment of debt (dollars in thousands, except per share data):

Earnings Outlook

Based on our current view of existing market conditions and certain current assumptions, our updated guidance for FFO per share (diluted) attributable to Alexandria Real Estate Equities, Inc.’s common stockholders and earnings per share (diluted) attributable to Alexandria Real Estate Equities, Inc.’s common stockholders are as follows:

The following table provides a summary of our guidance issued this year for 2010 FFO per share (diluted):

(1)                   Comprised of $0.83 per share related to the loss on early extinguishment of debt in June 2010 upon completion of our Exchange Offer and the $0.03 per share estimated loss on early extinguishment of debt in July 2010 related to the repurchase of an additional $7.1 million principal amount of our 8% unsecured convertible notes for cash in a privately negotiated transaction.

(2)                   Our guidance for the year ended December 31, 2010 includes the weighted average shares of common stock outstanding assuming conversion of such outstanding 8% unsecured convertible notes pursuant to the if-converted method of accounting for each period before and after the Exchange Offer and the weighted average shares of common stock associated with the 5.6 million shares of common stock issued upon completion of the Exchange Offer.  The Exchange Offer did not impact weighted average shares of common stock outstanding in our guidance for purposes of calculating FFO per share (diluted) for the year ended December 31, 2010 since the shares issued in the Exchange Offer were already included in diluted weighted average shares of common stock outstanding pursuant to the if-converted method of accounting.
