Financial Results

For the fourth quarter of 2010, we reported funds from operations (“FFO”) attributable to Alexandria Real Estate Equities, Inc.’s common stockholders of $58,474,000, or $1.07 per share (diluted), compared to FFO attributable to Alexandria Real Estate Equities, Inc.’s common stockholders of $54,247,000, or $1.09 per share (diluted), for the fourth quarter of 2009.  For the year ended December 31, 2010, we reported FFO attributable to Alexandria Real Estate Equities, Inc.’s common stockholders of $179,764,000, or $3.52 per share (diluted), compared to FFO attributable to Alexandria Real Estate Equities, Inc.’s common stockholders of $234,696,000, or $5.52 per share (diluted), for the year ended December 31, 2009.  During the year ended December 31, 2010, we recognized losses on early extinguishment of debt of approximately $45.2 million related to the repurchases, in privately negotiated transactions, of approximately $83 million of certain of our 3.70% unsecured convertible notes and the retirement of substantially all $240 million of our 8% unsecured convertible notes.  FFO attributable to Alexandria Real Estate Equities, Inc.’s common stockholders for the year ended December 31, 2010 excluding the losses on early extinguishment of debt was $224,538,000, or $4.40 per share (diluted).  During the year ended December 31, 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 of certain of our 3.70% unsecured convertible notes.  Additionally, during the year ended December 31, 2009, we recognized income of approximately $7.2 million for a cash payment related to real estate acquired in November 2007 and we recognized additional rental income of approximate ly $18.5 million related to a modification of a lease for a property in South San Francisco, California.  FFO attributable to Alexandria Real Estate Equities, Inc.’s common stockholders for the year ended December 31, 2009 excluding these items was $198,013,000, or $4.65 per share (diluted).  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 54,893,410 and 49,547,402 for the fourth quarter of 2010 and 2009, respectively, and 51,043,462 and 42,554,804 for the year ended December 31, 2010 and 2009, respectively.

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 items between GAAP net income attributable to Alexandria Real Estate Equities, Inc.’s common stockholders and FFO attributable to Alexandria Real Estate E quities, Inc.’s common stockholders is depreciation and amortization expense and gain on sales of property. Depreciation and amortization expense for the three months ended December 31, 2010 and 2009 was $34,551,000 and $29,004,000, respectively.  Depreciation and amortization expense for the year ended December 31, 2010 and 2009 was $126,640,000 and $118,508,000, respectively.  Net income attributable to Alexandria Real Estate Equities, Inc.’s common stockholders for the fourth quarter of 2010 was $83,243,000, or $1.52 per share (diluted), compared to net income attributable to Alexandria Real Estate Equities, Inc.’s common stockholders of $21,650,000, or $0.49 per share (diluted), for the fourth quarter of 2009.  Net income attributable to Alexandria Real Estate Equities, Inc.’s common stockholders for the year ended December��31, 2010 was $105,941,000, or $2.19 per share (diluted), compared to net income attributable to Alexandria Real E state Equities, Inc.’s common stockholders of $104,974,000, or $2.72 per share (diluted), for the year ended December 31, 2009.

(1)Due to the loss on early extinguishment of debt recognized in the three months ended June 30, 2010, our FFO results for the three months ended June 30, 2010 did not assume conversion of our 8% unsecured convertible notes for FFO per share (diluted) purposes as the impact to FFO per share was antidilutive for the period pursuant to the if-converted method of accounting.  Excluding the losses on early extinguishment of debt, the impact of the assumed conversion of our 8% unsecured convertible notes would have been dilutive to FFO (diluted) for the three months ended June 30, 2010.  For all periods since issuance of the notes in April 2009, except for the three months ended June 30, 2010, ther e 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 assumed conversion of our 8% unsecured convertible notes pursuant to the if-converted method of accounting.

Leasing Activity

For the fourth quarter of 2010, we executed a total of 40 leases for approximately 1,074,000 rentable square feet at 30 different properties (excluding month-to-month leases).  Of this total, approximately 758,000 rentable square feet related to new or renewal leases of previously leased space (renewed/released space) and approximately 316,000 rentable square feet related to developed, redeveloped, or previously vacant space.  Of the 316,000 rentable square feet, approximately 275,000 rentable square feet were related to our development or redevelopment programs, with the remaining approximately 41,000 rentable square feet related to previously vacant space.  Rental rates for these new or renewal leases (renewed/released space) were on average approximately 4.3% higher on a GAAP basis than rental rates for the respective expiring leases.

For the year ended December 31, 2010, we executed a total of 142 leases for approximately 2,744,000 rentable square feet at 71 different properties (excluding month-to-month leases).  Of this total, approximately 1,778,000 rentable square feet related to new or renewal leases of previously leased space and approximately 966,000 rentable square feet related to developed, redeveloped, or previously vacant space.  Of the 966,000 rentable square feet, approximately 712,000 rentable square feet were related to our development or redevelopment programs, with the remaining approximately 254,000 rentable square feet related to previously vacant space.  Rental rates for these new or renewal leases were on average approximately 4.9% higher on a GAAP basis than rental rates for the respective expiring leases.

As of December 31, 2010, approximately 96% of our leases (on a rentable square footage basis) were triple net leases, requiring tenants to pay substantially all real estate taxes, insurance, utilities, common area, and other operating expenses (including increases thereto) in addition to base rent.  Additionally, approximately 93% of our leases (on a rentable square footage basis) provided for the recapture of certain capital expenditures, and approximately 91% 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.

Unsecured Credit Facility

In January 2011, we entered into a third amendment (the “Third Amendment”) to our second amended and restated credit agreement dated October 31, 2006, as further amended on December 1, 2006 and May 2, 2007 (the “Existing Credit Agreement,” and as amended by the Third Amendment, the “Amended Credit Agreement”), with Bank of America, N.A., as administrative agent, and certain lenders. The Third Amendment amended the Existing Credit Agreement to, among other things, increase the maximum permitted borrowings under the credit facilities from $1.9 billion to $2.25 billion, consisting of a $1.5 billion unsecured line of credit (increased from $1.15 billion) and a $750 million unsecured term loan (together the “Unsecured Credit Facility”) and provide an accordion option to increase commitments under the Unsecured Credit Facility by up to an ad ditional $300 million.  Borrowings under the Unsecured Credit Facility will bear interest at LIBOR or the specified base rate, plus in either case a margin specified in the Amended Credit Agreement (the “Applicable Margin”).  The Applicable Margin for LIBOR borrowings under the revolving credit facility was initially set at 2.4%.  The Applicable Margin for the LIBOR borrowings under the unsecured term loan was not amended in the Third Amendment and was 1.0% as of December 31, 2010.

Under the Third Amendment, the maturity date for the unsecured revolving credit facility will be January 2015, assuming we exercise our sole right under the amendment to extend this maturity date twice by an additional six months after each exercise.  The maturity date for the $750 million unsecured term loan remained unchanged at October 2012, assuming we exercise our sole right to extend the maturity date by one year.  The Third Amendment modified certain financial covenants with respect to the Unsecured Credit Facility, including the fixed charge coverage ratio, secured debt ratio, leverage ratio, and minimum book value, and added covenants relating to an unsecured leverage ratio and unsecured debt yield.

Unsecured Convertible Notes

3.7% Unsecured Convertible Notes

In December 2010, we repurchased, in privately negotiated transactions, approximately $82.8 million of our 3.70% unsecured convertible notes at an aggregate cash price of approximately $84.6 million.  As a result of the repurchases, we recognized a loss on early extinguishment of debt of approximately $2.4 million during the fourth quarter of 2010.  In January 2011, we repurchased, in privately negotiated transactions, additional 3.70% unsecured convertible notes aggregating approximately $42.9 million at an aggregate cash price of approximately $44.1 million.  We recognized losses on early extinguishment of debt of approximately $1.2 million during January 2011.  As of February 2, 2011, approximately $259.1 million in principal was outstanding, including $5.4 million of unamortized discount.

Unsecured Convertible Notes (continued)

8% Unsecured Convertible Notes

In June 2010, we completed an exchange (the “Exchange Offer”) of approximately $232.7 million of our 8% unsecured convertible notes for consideration of 24.1546 shares of our common stock, a cash premium of $180 per $1,000 principal amount of the notes, plus accrued and unpaid interest.  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, the Exchange Offer did not by itself impact our total weighted average shares of common stock outstanding for purposes of calculating FFO per share (diluted).  In July 2010, we repurchased, in a privately negotiated transaction, approximately $7.1 million of our 8% unsecured convertible notes for an aggregate cash price of approximately $12.8 million.  Thus, in the Exchan ge Offer and this privately negotiated transaction, we retired $239.8 million of our 8% unsecured convertible notes (representing substantially all $240 million outstanding principal amount of our 8% unsecured convertible notes).  In connection with the retirement of our 8% unsecured convertible notes, we recognized losses on early extinguishment of debt of approximately $42.8 million for the year ended December 31, 2010.  As of December 31, 2010, $250,000 in principal was outstanding, including $20,000 of unamortized discount.

Acquisitions

In August 2010, we announced that we had entered into definitive agreements to acquire three life science properties and other selected assets and interests of privately-held Veralliance Properties, Inc. (“Veralliance”), including continuing services from Veralliance Founder and President, Daniel Ryan and other key management and operational personnel. Veralliance was a San Diego-based corporate real estate solutions company focused on the acquisition, development, and management of office and life science assets in Southern California. The three life science properties, located in San Diego, California, contain an aggregate 161,000 rentable square feet and were acquired for an aggregate purchase price of approximately $50.0 million consisting of approximately $35.2 million in cash and our assumption of two secured loans aggregating approximately $14.8 million . We completed the acquisition of one of these properties in the third quarter of 2010 and completed the acquisitions of the other two properties in the fourth quarter of 2010.

In October 2010, we acquired a life science campus in the San Diego market aggregating approximately 347,000 rentable square feet for approximately $128 million.  The purchase of this life science campus included land supporting the future development of additional life science buildings aggregating approximately 420,000 rentable square feet.  At the time of this acquisition, the campus was subject to a 15-month lease with Biogen Idec Inc.  In December 2010, we executed a new lease for the entire 347,000 rentable square foot campus pursuant to a 20-year lease with Illumina, Inc. (“Illumina”) and, pursuant to the lease, also commenced the ground-up development of a building aggregating approximately 123,000 rentable square feet on the campus.  Illumina has the right to further expand the premises and lease one to three additional buildings that may be built on this campus.

In December 2010, we acquired one property in the San Diego market aggregating approximately 373,000 rentable square feet and one property in the Suburban Washington, D.C. market aggregating approximately 50,000 rentable square feet for approximately $114 million and approximately $14 million, respectively.

Dispositions

In November 2010, we completed sales of land parcels in Mission Bay, San Francisco for an aggregate sales price of approximately $278 million at a gain of approximately $59 million. The sales of the land parcels resulted in a reduction of our preconstruction developable square footage by approximately 2.0 million square feet in the Mission Bay, San Francisco submarket.  The cash proceeds from these sales were used to repay outstanding borrowings under our unsecured line of credit.

Note Regarding Funds from Operations

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, acc ordingly, 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.
