ended June 30, 2009 to the six months ended June 30, 2008, FFO attributable to Alexandria Real Estate Equities, Inc.’s common stockholders and FFO attributable to Alexandria Real Estate Equities, Inc.’s common stockholders per share (diluted) increased 54% and 29%, respectively.  In the second quarter of 2009, we recognized a gain on early extinguishment of debt of approximately $11,254,000 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 $7,242,000 for a cash payment related to real estate acquired in November 2007.  For purposes of this paragraph, FFO attributable to Alexandria Real Estate Equities, Inc.’s common stockholders includes the effect of the assumed conversion of our 8% unsecured convertible notes.

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 GAAP net income attributable to Alexandria Real Estate Equities, Inc.’s common stockholders 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, 2009 and 2008 was $29,722,000 and $27,003,000, respectively.  Depreciation and amortization expense for the six months ended June 30, 2009 and 2008 was $61,168,000 and $52,813,000, respectively.  Net income attributable to Alexandria Real Estate Equities, Inc.’s common stockholders for the second quarter of 2009 was $35,498,000, or $0.82 per share (diluted), compared to net income attributable to Alexandria Real Estate Equities, Inc.’s common stockholders of $19,421,000, or $0.61 per share (diluted), for the second quarter of 2008.  Net income attributable to Alexandria Real Estate Equities, Inc.’s common stockholders for the six months ended June 30, 2009 was $68,287,000, or $1.81 per share (diluted), compared to net income attributable to Alexandria Real Estate Equities, Inc.’s common stockholders of $52,195,000, or $1.65 per share (diluted), for the six months ended June 30, 2008.  For purposes of this paragraph, net income attributable to Alexandria Real Estate Equities, Inc.’s common stockholders includes the effect of the assumed conversion of our 8% unsecured convertible notes.

For the second quarter of 2009, we executed a total of 49 leases for approximately 473,000 rentable square feet of space at 27 different properties (excluding month-to-month leases).  Of this total, approximately 368,000 rentable square feet related to new or renewal leases of previously leased space and approximately 105,000 rentable square feet related to developed, redeveloped or previously vacant space.  Of the 105,000 rentable square feet, approximately 65,000 rentable square feet were delivered from our development or redevelopment programs, with the remaining approximately 40,000 rentable square feet related to previously vacant space.  Rental rates for these new or renewal leases were on average approximately 3.3% higher (on a GAAP basis) than rental rates for expiring leases.

For the six months ended June 30, 2009, we executed a total of 82 leases for approximately 936,000 rentable square feet of space at 38 different properties (excluding month-to-month leases).  Of this total, approximately 618,000 rentable square feet related to new or renewal leases of previously leased space and approximately 318,000 rentable square feet related to developed, redeveloped or previously vacant space.  Of the 318,000 rentable square feet, approximately 108,000 rentable square feet were delivered from our development or redevelopment programs, with the remaining approximately 210,000 rentable square feet related to previously vacant space.  Rental rates for these new or renewal leases were on average approximately 4.0% higher (on a GAAP basis) than rental rates for expiring leases.

During the six months ended June 30, 2009, we sold three properties aggregating 64,218 rentable square feet to a life science user.  These properties were located in San Diego and were sold for approximately $14,449,000 at a gain of approximately $2,234,000.  As of June 30, 2009, one property with approximately 92,711 rentable square feet was classified as “held for sale” and is expected to be sold to a life science user.

In July 2009, we announced that we entered into a 15-year lease with Eli Lilly and Company (“Lilly”) as the anchor tenant at the Alexandria Center for Science and Technology at East River Science Park (“the Alexandria Center”), a highly advanced state-of-the-art urban science park.  Lilly has leased approximately 91,000 rentable square feet, as well as an additional approximately 9,000 rentable square feet of core services space, at the Alexandria Center, which will become the new research headquarters for ImClone Systems, a wholly-owned subsidiary of Lilly, and New York City’s life science collaboration and translational research epicenter.

In July 2009, we executed a term sheet with an insurance company for a secured loan approximating $120 million.  The term sheet includes a 10-year term and is secured by several operating properties.

Additionally in July 2009, we announced that Krupal Raval will join the Company as Vice President – Capital Markets.  Mr. Raval joins the Company with seven solid years as a real estate equity research analyst.  Mr. Raval’s career experience includes being a top ranked research analyst at Fidelity Management and Research and Citi/Smith Barney in addition to recognition as a National Scholar from Cornell University.  While at Citi/Smith Barney, the REIT equity research team was ranked number one for several years by Institutional Investors.

As of June 30, 2009, approximately 89% of our leases (on a rentable square footage basis) were triple net leases, requiring tenants to pay substantially all real estate taxes and 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 93% 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.

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:

	2009
FFO per share (diluted) (1)	$5.60 (1)
Earnings per share (diluted) (1)	$2.58 (1)

(1) Our guidance for 2009 has been updated to reflect the $7.2 million gain for a cash payment related to real estate acquired in November 2007 and also reflects the $11.3 million gain on early extinguishment of debt. Our guidance for FFO per share (diluted) for the twelve months ended December 31, 2009 assumes conversion of our 8% unsecured convertible notes as the impact of the notes is expected to be dilutive under the “if-converted” method pursuant to Statement of Financial Accounting Standards No. 128, “Earnings per Share”. Our guidance for earnings per share (diluted) for the twelve months ended December 31, 2009, however, does not assume conversion as the “if-converted” method for our 8% unsecured convertible notes is expected to be anti-dilutive.

Alexandria Real Estate Equities, Inc. (“Alexandria”) has a very broad and diversified quality client tenant base. As of June 30, 2009, on a rental revenue basis by sector, Alexandria’s multinational pharmaceutical client tenants represented approximately 27% of its client tenant mix, led by its top three client tenants Novartis AG, GlaxoSmithKline plc and Roche Holding Ltd; public biopharmaceutical companies represented approximately 21% and included the three largest in the sector, Amgen Inc., Gilead Sciences, Inc. and Celgene Corporation; revenue producing life science product and service companies represented approximately 17%, led by Quest Diagnostics Incorporated, Laboratory Corporation of America Holdings and Qiagen N.V.; government agencies and renown medical and research institutions represented approximately 14%, including The Scripps Research Institute, Massachusetts Institute of Technology, Fred Hutchinson Cancer Research Center, University of Washington, the Burnham Institute for Medical Research and the United States Government; private biopharmaceutical companies represented approximately 13% and were dominated by high-quality, leading-edge companies with blue chip venture and institutional investors, including Ambrx, Inc., BrainCells Inc., Ikaria Holdings, Inc., Macrogenics Inc. and Proteostatsis Therapeutics, Inc.;  the remaining approximately 8% consisted of traditional office tenants.  The two fastest growing sectors by revenue currently include leading institutional and multinational pharmaceutical client tenants.  Alexandria’s innovative business model, very strong and unique life sciences and underwriting skills with substantial experience and expertise, long-term life science industry relationships and sophisticated management with both real estate and life science operating experience and expertise, set Alexandria apart from all other publicly-traded real estate investment trusts (“REITs”).

Alexandria Real Estate Equities, Inc., Landlord of Choice to the Life Science Industry®, is the largest owner and pre-eminent first-in-class REIT focused principally on science-driven cluster formation.  Alexandria is the leading provider of high-quality environmentally sustainable real estate, technical infrastructure, and services to the broad and diverse life science industry.  Client tenants include institutional (universities and independent not-for-profit institutions), pharmaceutical, biopharmaceutical, medical device, product, service and translational entities, as well as government agencies.  Alexandria’s operating platform is based on the principle of “clustering,” with assets and operations located in key life science markets.  Our asset base approximates 12.8 million rentable square feet consisting of 156 properties approximating 11.7 million rentable square feet (including spaces undergoing active redevelopment) and properties undergoing ground-up development approximating an additional 1.1 million rentable square feet.

(a)	Rental income for the three months ended March 31, 2009 and December 31, 2008 includes approximately $18.5 million and $11.3 million, respectively, of additional income related to a modification of a lease for a property in South San Francisco, California.
(b)	Includes other income of approximately $7.2 million for a cash payment related to real estate acquired in November 2007.
(c)	The historical results above include the retrospective impact of FSP APB 14-1, FSP EITF 03-6-1 and SFAS 160.  See page 8 for a reconciliation of net income attributable to Alexandria Real Estate Equities, Inc.’s common stockholders to FFO attributable to Alexandria Real Estate Equities, Inc.’s common stockholders assuming effect of dilutive securities.
(d)	Dividend payout ratio (common stock) is the ratio of the absolute dollar amount of dividends on our common stock (common stock shares outstanding on the respective record date multiplied by the related dividend per share) to FFO attributable to Alexandria Real Estate Equities, Inc.’s common stockholders. The historical ratios above include the retrospective impact of FSP APB 14-1, FSP EITF 03-6-1 and SFAS 160.
(e)	Represents capitalized interest assuming conversion of our 8% unsecured convertible notes pursuant to SFAS 128.  As of June 30, 2009, assets for which capitalization of interest is required pursuant to Statement of Financial Accounting Standards No. 34, “Capitalization of Interest Cost” (“SFAS 34”), approximated $1.4 billion.  This amount is classified as properties undergoing development and redevelopment, and land held for development on our balance sheet.  The weighted average interest rate used in the calculation of capitalized interest required pursuant to SFAS 34 assuming conversion of our 8% unsecured convertible notes was approximately 5.23% and 4.84% for the three months ended June 30, 2009 and March 31, 2009, respectively.  The majority of the increase in interest capitalized in the second quarter of 2009 as compared to first quarter 2009 is due to the increase in our weighted average interest rate used for capitalization.  SFAS 34 requires the interest rate for capitalization to be based on applicable interest costs related to borrowings outstanding during the period, including the impact of interest rate swap agreements, debt premiums/discounts and amortization of loan fees.
(f)	Includes properties “held for sale” during the applicable periods such assets were “held for sale.”
(g)	During the first quarter of 2009, we sold three assets located in the San Diego market.  During the fourth quarter of 2008, we sold one asset located in the Eastern Massachusetts market.  During the second quarter of 2008, we sold one asset located in the San Diego market.

Interest pay rates represent the interest rate we will pay for one month LIBOR under the respective interest rate swap agreement. These rates do not include any spread in addition to one month LIBOR that is due monthly as interest expense.

In May 2009, we entered into an interest rate cap agreement with a notional amount approximating $38.4 million effective May 15, 2009 and terminating on January 3, 2012.  The agreement sets a ceiling on one month LIBOR at 2.50% related to one secured note.

This summary represents operating data for all properties that were fully operating for the entire periods presented for the quarter periods (the “Second Quarter Same Properties”) and for the Six Month periods (the “Six Months Same Properties”).  Same property occupancy for the quarters ended June 30, 2009 and 2008 was 94.8% and 95.5%, respectively.  Same Property Occupancy for the six months ended June 30, 2009 and 2008 was 94.9% and 95.0%, respectively. Properties undergoing redevelopment are excluded from same property results.

Revenue less operating expenses computed in accordance with GAAP is total revenue associated with the Second Quarter Same Properties and Six Months Same Properties, as applicable (excluding lease termination fees, if any), less property operating expenses.  Under GAAP, rental revenue is recognized on a straight-line basis over the respective lease terms.  Revenue less operating expenses on a cash basis is total revenue associated with the Second Quarter Same Properties and Six Months Same Properties (excluding lease termination fees, if any), less property operating expenses, adjusted to exclude the effect of straight-line rent adjustments required by GAAP.  Straight-line rent adjustments for the quarters ended June 30, 2009 and 2008 for the Second Quarter Same Properties were $1,317,000 and $3,705,000, respectively.  Straight-line rent adjustments for the six months ended June 30, 2009 and 2008 for the Six Months Same Properties were $2,644,000 and $6,549,000, respectively.  We believe that revenue less operating expenses on a cash basis is helpful to investors as an additional measure of operating performance because it eliminates straight-line rent adjustments to rental revenue.

Fees received from tenants in connection with termination of their leases, if any, are excluded from revenue in the Summary of Same Property Comparisons. As of June 30, 2009, approximately 89% of our leases (on a rentable square footage basis) were triple net leases, requiring tenants to pay substantially all real estate taxes and 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.

In the first quarter of 2009, we recognized additional rental income related to a modification of a lease for a property in South San Francisco.  The operating results of this property have been excluded from the same property results for the six months ended June 30, 2009.  Including the results of this property, six months 2009 GAAP same property revenue less operating expenses would have increased 14.2%.

(1) Quarterly leasing statistic (shorter lease terms) may be impacted by certain leasing activity in an individual quarter period. Leasing statistics over a longer period of time (6-12 months) generally are a better indicator of leasing trends for our business. Average lease terms over the past five years (2004-2008) averaged approximately 4.5 years and 7.4 years for renewed/released space leased and developed/redeveloped/ vacant space leased, respectively.

In December 2008, the Company entered into a modification of a lease in South San Francisco resulting in the recognition of additional rental income approximating $11.3 million and $18.5 million in the fourth quarter of 2008 and the first quarter of 2009, respectively.  The Company completed the lease modification in December 2008 in order to lease the space to a high quality life science company.  The leasing activity above excludes the impact of activity at this property due to the significance of the additional rental income recognized pursuant to the lease modification.

Construction in progress includes the following value add activities as of June 30, 2009 (in thousands):

Value Add Activities	Amount
Redevelopment projects	$	149,510
Development projects	410,316
Preconstruction projects	597,149
New markets and other projects	249,476
Total	$	1,406,451

A key component of our business is our value add redevelopment and development programs.  These programs are focused on providing high quality generic office/laboratory space to meet the real estate requirements of various life science industry tenants. Redevelopment projects consist of the permanent change in use of office, warehouse and shell space into generic office/laboratory space, including the conversion of single tenancy space to multi-tenancy spaces. Development projects consist of the ground-up development of generic office/laboratory facilities. We also have certain significant value add projects undergoing important and substantial preconstruction activities to bring these assets to their intended use. These critical activities add significant value for future ground-up development (which are projected to yield substantial revenues) and are required for the ultimate vertical construction of buildings. Pursuant to SFAS 34 and SFAS 67, we are required to capitalize construction and preconstruction costs directly related and essential to the construction of a project while activities are ongoing to prepare an asset for its intended use.  Capitalized interest assuming conversion of our 8% unsecured convertible notes for the three months ended June 30, 2009 was approximately $18.2 million. Pursuant to SFAS 34, the interest rate required for the purpose of calculating capitalization of interest was approximately 5.23% for the three months ended June 30, 2009 assuming conversion of our 8% unsecured convertible notes.

Our remaining aggregate costs under contracts for the construction projects, including properties undergoing redevelopment and development and infrastructure improvements under the terms of leases, aggregated approximately $177 million. We expect payments for these obligations to occur over the next one to three years, subject to capital planning adjustments from time to time. Our final costs for these projects will ultimately depend on many factors, including construction requirements for each tenant, final lease negotiations and the amount of costs funded by each tenant.

Our significant value add projects include preconstruction activities at certain land parcels including: a) approximately 2.5 million developable square footage in San Francisco, including approximately 2.3 million developable square footage at Mission Bay, b) approximately 2.1 million developable square footage in Eastern Massachusetts, including approximately 1.7 million developable square footage located along Binney Street in Kendall Square and c) approximately 1.0 million developable square footage located in other key life science cluster markets.

San Francisco Bay – Mission Bay and South San Francisco Value Add Preconstruction Activities

The value add preconstruction activities in Mission Bay and South San Francisco will create high quality space in state-of-the-art environmentally sustainable facilities for our clients generating net operating income for the Company.  The entitlement process includes a multitude of activities necessary for the vertical construction of these high quality facilities including, among other items, regulatory approval, mapping, conceptual design, schematic design, design development, permitting, construction drawings and estimating. Our value add projects in Mission Bay and South San Francisco, that have been completed or are now under construction, have attracted Merck & Co., Inc., Celgene Corporation, Pfizer Inc., Roche Holdings Ltd and University of California, San Francisco.

The ability to provide significant additional space in high quality state-of-the-art environmentally sustainable facilities at Mission Bay is a unique opportunity to enhance our current high quality client tenant roster.  In addition to the opportunities located at Mission Bay, our asset base contains a broad pipeline of opportunities located in South San Francisco.  This includes, among others, a high quality facility with entitlements completed or in process totaling over 275,000 square feet and a four building campus totaling an additional 405,000 square feet located nearby existing well established and emerging life science companies in South San Francisco.

The Alexandria Center for Science and Technology at Mission Bay (“The Alexandria Center”) when completed will consist of 13 high quality facilities totaling approximately 2.7 million rentable square feet.  The Alexandria Center is organized into four discrete but highly interactive and collaborative campuses: the north campus which includes the 455 Mission Bay Boulevard project leased to Pfizer, Inc.; the east campus, featuring the ability to accommodate a corporate headquarters facility of more than one million square feet; the south campus which is directly across the street from the UCSF hospital complex and likely to become an important location for physicians, clinicians and translational researchers; and the west campus which features a wide range of unique life science client tenant spaces.

San Francisco Bay – Mission Bay and South San Francisco Value Add Preconstruction Activities (continued)

At the heart of Mission Bay is UCSF, one of the nation’s top generators of life science commercial enterprises and the number two recipient of grants from the National Institutes of Health.  At least 75 California life science companies, including two of the largest, Genentech, Inc. (now a subsidiary of Roche) and Chiron Corporation (now a subsidiary of Novartis AG), have been successfully launched by UCSF faculty or alumni.  UCSF’s expansion of major research functions to its Mission Bay campus serves as a hub for basic scientific inquiry and a meeting place for academics from around the world.  The wide range of UCSF’s sophisticated laboratories include the Center for Advanced Technology, as well as significant efforts in structural and chemical biology, molecular, cell and developmental biology, advanced microscopy, neurology and cardiology.  Finally, the UCSF Mission Bay hospital campus is in the design phase, and will initially offer 280 beds in an integrated facility to serve women, children and cancer patients. The overriding emphasis of this array of diverse life science entities is to translate research discoveries into viable commercial products to solve critical unmet medical needs.

Eastern Massachusetts Value Add Preconstruction Activities

Alexandria’s largest ongoing value add project in Eastern Massachusetts is located along Binney Street in Kendall Square, a five-minute walk from the Massachusetts Institute of Technology (“MIT”) campus.  In February 2009, the Cambridge City Council approved Alexandria’s petition for significantly increased zoning density in this location, enabling the future development of up to 1.7 million rentable square feet of office/laboratory space on multiple adjacent sites.  These sites currently hold income-producing low-rise buildings and surface parking lots, which, we believe, will eventually be replaced by high quality life science facilities in this desirable, land-constrained location.  We will continue to advance our entitlement efforts for this site.

Our significant value add projects in Eastern Massachusetts are located in Cambridge and nearby communities.  Cambridge is home to Harvard University (“Harvard”) and MIT, two of world’s leading universities for life science and technology research.  Both Harvard and MIT have a long and successful history of translational collaborations between academic scientists and industry.  Working with local venture capitalists and experienced entrepreneurs, the universities have created leading biotech companies such as Genzyme Corporation and Biogen Idec and well over a hundred smaller life science firms in Cambridge alone.  This fertile science and technology ecosystem has subsequently attracted investment by leading international pharmaceutical companies such as Novartis and GlaxoSmithKline and has led to the creation of important new independent research organizations in Cambridge, such as the Broad Institute and the Whitehead Institute for Biomedical Research.   Among the most recent new members of the Cambridge community are:  Microsoft’s New England Research and Development Center; Schlumberger-Doll Research Center; a Google engineering unit; and the Koch Center for Integrative Cancer Research at MIT.

Among Alexandria’s completed value add projects in Cambridge is the conversion of an approximately 175,000 square foot office building at Technology Square to office/laboratory use.  This space has been substantially leased to Sirtris Pharmaceuticals, a GlaxoSmithKline company, the Novartis Institutes of Biomedical Research, and a unit of Pfizer, Inc.  Another suburban building conversion resulted in a 59,000 square foot lease to a research division of Johnson & Johnson.

New Markets and Other Projects

A component of our business also includes ground-up development projects in new markets and other projects.  We have two development parcels in China. One development parcel is located in South China for a two-building project aggregating approximately 275,000 rentable square feet. This project is nearing shell completion.  The second development parcel is located in North China for a two-building project aggregating approximately 272,000 rentable square feet. As of June 30, 2009, our estimated remaining costs to complete shell construction for these projects in China were approximately $13 million.

Additionally, other projects include two above-ground parking structures under construction at Mission Bay in San Francisco and construction related to site work, plaza, park and underground parking at the Alexandria Center for Science and Technology at East River Science Park, New York City, a unique one-of-a-kind highly advanced state-of-the-art urban science park.

Definitions

June 30, 2009

This section contains an explanation of certain non-GAAP financial measures we provide in other sections of this document, as well as the reasons why management believes these measures provide useful information to investors about our financial condition or results of operations.  Additional detail can be found in our most recent annual report on Form 10-K and quarterly report on Form 10-Q, as well as other documents filed with or furnished to the SEC from time to time.

Funds from Operations

United States generally accepted accounting principles (“GAAP”) basis accounting for real estate assets utilizes historical cost accounting and assumes real estate values diminish over time.  In an effort to overcome the difference between real estate values and historical cost accounting for real estate assets, the Board of Governors of NAREIT established the measurement tool of Funds from Operations (“FFO”).  Since its introduction, FFO has become a widely used non-GAAP financial measure among real estate investment trusts (“REITs”).  We believe that FFO is helpful to investors as an additional measure of the performance of an equity REIT.  We compute FFO in accordance with standards established by the Board of Governors of NAREIT in its April 2002 White Paper (the “White Paper”) and related implementation guidance, which may differ from the methodology for calculating FFO utilized by other equity REITs, and, accordingly, may not be comparable to such other REITs.  The White Paper defines FFO as net income (loss) (computed in accordance with GAAP), excluding gains (or losses) from sales, plus real estate related depreciation and amortization, and after adjustments for unconsolidated partnerships and joint ventures.

FFO should not be considered as an alternative to net income (determined in accordance with GAAP) as an indication of financial performance, or to cash flows from operating activities (determined in accordance with GAAP) as a measure of our liquidity, nor is it indicative of funds available to fund our cash needs, including our ability to make distributions.

Adjusted Funds from Operations

Adjusted Funds from Operations (“AFFO”) is a non-GAAP financial measure we believe is a useful supplemental measure of our performance.  We compute AFFO attributable to Alexandria Real Estate Equities, Inc’s common stockholders by adding to or deducting from FFO attributable to Alexandria Real Estate Equities, Inc’s common stockholders (i) recurring and non-recurring capital expenditures required to maintain and re-tenant our properties, (ii) second generation tenant improvements and leasing costs on retenanted and renewal space (excludes redevelopment expenditures), (iii) capitalized income from development projects, (iv) gain on early extinguishment of debt, (v) amortization of loan fees, debt premiums/discounts and acquired above and below market leases, (vi) effects of deferred rent, (vii) non-cash compensation expense related to restricted stock awards and (viii) other non-cash income or charges.  AFFO is not intended to represent cash flow for the period, and it only provides an additional perspective on our ability to fund cash needs and make distributions to shareholders by adjusting the effect of the non-cash items included in FFO, as well as recurring capital expenditures and leasing costs.  We believe that net income attributable to Alexandria Real Estate Equities, Inc’s common stockholders is the most directly comparable GAAP financial measure to AFFO attributable to Alexandria Real Estate Equities, Inc’s common stockholders.  We also believe that AFFO attributable to Alexandria Real Estate Equities, Inc’s common stockholders provides useful information to the investment community about our financial position as compared to other REITs since AFFO is a widely reported measure used by other REITs.  However, other REITs may use different methodologies for calculating AFFO and, accordingly, our AFFO may not be comparable to other REITs.
