(2)	Assumes we exercise our sole option to extend the stated maturity date of April 30, 2016, by six months, twice, to April 30, 2017.
(3)	Assumes we exercise our sole option to extend the stated maturity date of June 30, 2015, by one year, to June 30, 2016.

(5)	Includes $550 million of our 4.60% unsecured senior notes payable due in April 2022, and $250,000 of our 8.00% unsecured senior convertible notes payable with a maturity date of April 15, 2014.

In June 2012, we closed a secured construction loan with aggregate commitments of $55 million.  The construction loan matures in June 2017, assuming we exercise our sole option to extend the stated maturity date of June 2015 by one year, twice.  The construction loan will be used to fund the majority of the cost to complete the development of a 100% pre-leased 170,618 rentable square feet life science laboratory building at 259 East Grand Avenue in the San Francisco Bay market.  The construction loan will bear interest at the London Interbank Offered Rate (“LIBOR”) or the base rate specified in the construction loan agreement, defined as the higher of either the prime rate being offered by our lender or the federal funds rate in effect on the day of borrowing (“Base Rate”), plus in either case a specified margin of 1.50% for LIBOR borrowings or 0.25% for Base Rate borrowings.  As of June 30, 2012, $55 million of commitments were available.

4.60% Unsecured senior notes payable

In February 2012, we completed a public $550 million offering of our unsecured senior notes payable at a stated interest rate of 4.60%.  The unsecured senior notes payable were priced at 99.915% of the principal amount with a yield to maturity of 4.61% and are due April 1, 2022.  The unsecured senior notes payable are unsecured obligations of the Company and are fully and unconditionally guaranteed by Alexandria Real Estate Equities, L.P., a wholly owned subsidiary of the Company.  The unsecured senior notes payable rank equally in right of payment with all other senior unsecured indebtedness.  However, the unsecured senior notes payable are effectively subordinated to existing and future mortgages and other secured indebtedness (to the extent of the value of the collateral securing such indebtedness) and to all existing and future preferred equity and liabilities, whether secured or unsecured, of the Company’s subsidiaries, other than Alexandria Real Estate Equities, L.P.  We used the net proceeds of this offering to prepay the outstanding principal balance of $250 million on our unsecured senior bank term loan (“2012 Unsecured Senior Bank Term Loan”) and to reduce the outstanding borrowings on our unsecured senior line of credit.

The requirements of the key financial covenants under our unsecured senior notes payable as of June 30, 2012, are as follows:

Covenant Ratios (1)	Requirement
Total Debt to Total Assets	Less than or equal to 60%
Consolidated EBITDA to Interest Expense	Greater than or equal to 1.5x
Unencumbered Total Asset Value to Unsecured Debt	Greater than or equal to 150%
Secured Debt to Total Assets	Less than or equal to 40%

(1) For a definition of the ratios used in the table above, refer to the Indenture dated February 29, 2012, which governs the unsecured senior notes payable, which was filed as an exhibit to our Current Report on Form 8-K filed with the SEC on February 29, 2012.

In addition, the terms of the Indenture, among other things, limit the ability of the Company, Alexandria Real Estate Equities, L.P., and the Company’s other subsidiaries to (1) consummate a merger, or consolidate or sell all or substantially all of the Company’s assets, and (2) incur certain secured or unsecured indebtedness.

Unsecured senior line of credit and unsecured senior bank term loans

In April 2012, we amended our $1.5 billion unsecured senior line of credit, with Merrill Lynch, Pierce, Fenner & Smith Incorporated, J.P. Morgan Securities Inc., and Citigroup Global Markets Inc. as joint lead arrangers, and certain lenders, to extend the maturity date of our unsecured senior line of credit, provide an accordion option for up to an additional $500 million, and reduce the interest rate for outstanding borrowings. The maturity date of the unsecured senior line of credit was extended to April 2017, assuming we exercise our sole right to extend the maturity date twice by an additional six months after each exercise. Borrowings under the unsecured senior line of credit bear interest at LIBOR or the base rate specified in the amended unsecured senior line of credit and unsecured senior bank term loan agreements, plus in either case a specified margin (the “Applicable Margin”). The Applicable Margin for LIBOR borrowings under the unsecured senior line of credit was set at 1.20%, down from 2.40% in effect immediately prior to the modification. In addition to the Applicable Margin, our unsecured senior line of credit is subject to an annual facility fee of 0.25%.  In connection with the modification of our unsecured senior line of credit in April 2012, we recognized a loss on early extinguishment of debt of approximately $1.6 million related to the write-off of a portion of unamortized loan fees.

In April 2012, we amended our 2016 unsecured senior bank term loan (“2016 Unsecured Senior Bank Term Loan”) and 2017 unsecured senior bank term loan (“2017 Unsecured Senior Bank Term Loan”), conforming the financial covenants contained in our unsecured senior bank term loan agreements to those contained in our amended $1.5 billion unsecured senior line of credit.

In February 2012, we recognized a loss on early extinguishment of debt of approximately $0.6 million related to the write-off of unamortized loan fees as a result of the early repayment of $250 million of our 2012 Unsecured Senior Bank Term Loan.  In June 2011, we recognized a loss on early extinguishment of debt of approximately $1.2 million related to the write-off of unamortized loan fees as a result of the early repayment of $500 million of our 2012 Unsecured Senior Bank Term Loan.

The requirements of the key financial covenants under our unsecured senior line of credit and unsecured senior bank term loans as of June 30, 2012, are as follows:

Covenant Ratios (1)	Requirement
Leverage Ratio	Less than or equal to 60.0%
Fixed Charge Coverage Ratio	Greater than or equal to 1.50x
Secured Debt Ratio	Less than or equal to 40.0%
Unsecured Leverage Ratio	Less than or equal to 60.0%
Unsecured Interest Coverage Ratio	Greater than or equal to 1.75x

(1) For a definition of the ratios used in the table above, refer to the amended unsecured senior line of credit and unsecured senior bank term loan agreements, dated as of April 30, 2012, which are filed as Exhibits 10.2, 10.3, and 10.4 to this Quarterly Report on Form 10-Q.

In addition, the terms of the unsecured senior line of credit and unsecured senior bank term loan agreements, among other things, limit the ability of the Company, Alexandria Real Estate Equities, L.P., and the Company’s subsidiaries to (1) consummate a merger, or consolidate or sell all or substantially all of the Company’s assets, and (2) incur certain secured or unsecured indebtedness.

(1)Our 3.70% unsecured senior convertible notes (“3.70% Unsecured Senior Convertible Notes”) require that upon conversion, the entire principal amount is to be settled in cash, and any excess value above the principal amount, if applicable, is to be settled in shares of our common stock.  Based on the December 31, 2011, closing price of our common stock of $68.97, and the conversion price of our 3.70% Unsecured Senior Convertible Notes of $117.36 as of December 31, 2011, the if-converted value of the notes did not exceed the principal amount as of December 31, 2011, and accordingly, no shares of our common stock would have been issued if the notes had been settled on December 31, 2011.

3.70% unsecured senior convertible notes

During the six months ended June 30, 2011, we recognized an aggregate loss on early extinguishment of debt of approximately $2.5 million related to the repurchase, in privately negotiated transactions, of approximately $96.1 million of certain of our 3.70% Unsecured Senior Convertible Notes.

During January 2012, we repurchased approximately $83.8 million in principal amount of our 3.70% Unsecured Senior Convertible Notes at par, pursuant to options exercised by holders thereof under the indenture governing the notes.  During April 2012, we repurchased the remaining outstanding $1.0 million in principal amount of the notes.  We did not recognize a gain or loss as a result of either repurchase during the six months ended June 30, 2012.

The following table outlines our interest expense for the three and six months ended June 30, 2012 and 2011 (in thousands):
