You can identify some of the forward-looking statements by the use of forward-looking words such as "believes", "expects", "may", "will", "should", "seeks", "intends", "plans", "estimates" or "anticipates", or the negative of these words or similar words. Forward-looking statements involve inherent risks and uncertainties regarding events, conditions and financial trends that may affect our future plans of operation, business strategy, results of operations and financial position. A number of important factors could cause actual results to differ materially from those included within or contemplated by the forward-looking statements, including, but not limited to, those described below under the headings "Item 1. Business-Business Risks" and "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations". We do not undertake any responsibility to update any of these factors or to announce publicly any revisions to any of the forward-looking statements, whether as a result of new information, future events or otherwise.

As used in this Form 10-K, references to the "Company", "we", "our", and "us" refer to Alexandria Real Estate Equities, Inc. and its subsidiaries.

Item 1. Business

General

We are a Maryland corporation formed in October 1994 that has elected to be taxed as a real estate investment trust ("REIT") for federal income tax purposes. We are engaged primarily in the ownership, operation, management, acquisition, expansion and selective redevelopment and development of high quality, strategically located properties containing office/ laboratory space designed and improved for lease primarily to pharmaceutical, biotechnology, life science product, service, biodefense, educational and translational medicine institutions/entities, as well as related government agencies (collectively, the "life science industry"). Properties leased to tenants in the life science industry typically consist of suburban office buildings containing scientific research and development laboratories and other improvements that are generic to tenants operating in the life science industry. We refer to such properties as "life science properties". As of December 31, 2004, we owned 112 properties (collectively, the "properties") in nine states containing approximately 7.4 million rentable square feet of office/ laboratory space.

Business and Growth Strategy

We focus our property operations and investment activities principally in the following life science markets:

Our tenant base is broad and diverse within the life science industry and reflects our focus on regional, national and international tenants with substantial financial and operational resources. For a more detailed description of our properties and tenants, see "Item 2. Properties." We have an experienced Board of Directors and are led by a senior management team with extensive experience in both the real estate and life science industries.

We seek to maximize growth in funds from operations ("FFO") and cash available for distribution to stockholders through the ownership, operation, management, acquisition, expansion and selective redevelopment and development of life science properties. See "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations-Funds from Operations" for a discussion of how we compute and view FFO, as well as a discussion of other measures of cash flow. In particular, we seek to increase FFO and cash available for distribution by:

Internal Growth. We seek to achieve internal growth from several sources. For example, we seek to:

Our ability to negotiate contractual rent escalations in future leases and to achieve increases in rental rates will depend upon market conditions and the demand for life science properties at the time the leases are negotiated and the increases are proposed.

Acquisitions. We seek to identify and acquire high quality life science properties in our target markets on a selective basis. Critical evaluation of prospective property acquisitions is an essential component of our acquisition strategy. When evaluating acquisition opportunities, we assess a full range of matters relating to the properties, including the:

Redevelopment. We seek to enhance our growth by redeveloping existing office, warehouse or vacant space as generic laboratory space that can be leased at higher rates. As of December 31, 2004, we had 17 properties in our redevelopment program that contained a total of approximately 1,296,000 square feet. Of this total, approximately 669,000 square feet were under redevelopment and currently vacant, and the remaining approximately 627,000 square feet were currently leased. We have also identified approximately 625,000 square feet of additional space in our existing portfolio for potential redevelopment.

Development. Our development strategy is primarily to pursue selective build-to-suit projects where we expect to achieve investment returns that will equal or exceed our returns on acquisitions. We generally have undertaken build-to-suit projects only if our investment in infrastructure will be substantially made for generic, rather than tenant-specific, improvements. As of December 31, 2004, we had six parcels of land under development for approximately 358,000 square feet of office/laboratory space. In addition, we currently own parcels of land and may expand existing properties, representing an aggregate future development potential of approximately 3,719,000 rentable square feet of office/laboratory space.

Financing/Working Capital. We believe that cash provided by operations, our unsecured line of credit and our unsecured term loan will be sufficient to fund our working capital requirements. We generally expect to finance future acquisitions and redevelopment and development projects through our unsecured line of credit and unsecured term loan and, then, to refinance some or all of that indebtedness periodically with additional equity or debt capital. We may also issue shares of our common stock, preferred stock or interests in our subsidiaries to fund future operations. See "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations-Unsecured Line of Credit and Unsecured Term Loan".

We seek to maintain a balance between the amounts of our fixed and variable debt with a view to moderating our exposure to interest rate risk. We also use financial instruments, such as interest rate swap agreements, to hedge a portion of our exposure to the variable interest rates associated with our unsecured line of credit and unsecured term loan. Interest rate swap agreements involve an exchange of fixed and floating interest rate payments without the exchange of the underlying principal or "notional amount". Interest received under our current interest rate swap agreements is based on the one-month LIBOR rate. See "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations-Liquidity and Capital Resources" for a more complete discussion of our unsecured line of credit, unsecured term loan, interest rate swap agreements and other outstanding indebtedness.

Preferred Securities. We have in the last year, and expect to continue, to issue additional series of preferred stock that are senior to our common stock. At December 31, 2004, we had approximately $187.0 million of preferred stock outstanding. The preferred stock has general preference rights with respect to liquidation and quarterly distributions. In June 2004, we completed a public offering of 5,185,500 shares of our 8.375% Series C cumulative redeemable preferred stock with aggregate proceeds of approximately $124.0 million. In July 2004, we redeemed all 1,543,500 outstanding shares of our 9.50% Series A cumulative redeemable preferred stock. Future redemptions or repurchases of our preferred securities may occur after their respective call dates. See "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations - Other Resources and Liquidity Requirements".

Business Risks

We Are Largely Dependent on the Life Science Industry for Revenues from Lease Payments

In general, our strategy is to invest primarily in properties used by tenants in the life science industry. Our business could be adversely affected if the life science industry experiences an economic downturn. Because of our industry focus, events within the life science industry may have a more pronounced effect on our ability to make distributions to our stockholders than if we had more diversified investments. Also, some of our properties may be better suited for a particular life science industry tenant and could require modification before we are able to release vacant space to another life science industry tenant. Generally, our properties may not be suitable for lease to traditional office tenants without significant expenditures on renovations.

Our Tenants May Not Be Able to Pay Us if They Are Unsuccessful in Discovering, Developing, Making or Selling Their Products and Technologies

Our life science industry tenants are subject to a number of risks, including the following, any one or more of which may adversely affect their ability to make rental payments to us.

We cannot assure you that our tenants will be able to develop, make, market or sell their products and technologies due to the risks inherent in the life science industry. Any tenant that is unable to avoid, or sufficiently mitigate, the risks described above, may have difficulty making rental payments to us.

We Could be Held Liable for Damages Resulting from Our Tenants' Use of Hazardous Materials

Many of our life science industry tenants engage in research and development activities that involve the controlled use of hazardous materials, chemicals and biological and radioactive compounds. In the event of contamination or injury from the use of these hazardous materials, we could be held liable for damages that result. This liability could exceed our resources and any recovery available through any applicable environmental remediation insurance coverage, and could adversely affect our ability to make distributions to our stockholders.

Together with our tenants, we must comply with federal, state and local laws and regulations governing the use, manufacture, storage, handling and disposal of hazardous materials and waste products. Failure to comply with, or changes in, these laws and regulations could adversely affect our business or our tenants' business and their ability to make rental payments to us.

The Inability of Any Tenant to Pay Us Rent Could Adversely Affect Our Business

Our revenues are derived primarily from rental payments and reimbursement of operating expenses under our leases. If our tenants, especially significant tenants, fail to make rental payments under their leases, our financial condition, cash flow and our ability to make distributions to our stockholders could be adversely affected.

As of December 31, 2004, we had 249 leases with a total of 213 tenants. Of our 112 properties, 64 properties were occupied by a single tenant. Our three largest tenants accounted for approximately 11.6% of our aggregate annualized base rent, or approximately 5.2%, 3.7% and 2.7%, respectively. "Annualized base rent" means the annualized fixed base rental amount in effect as of December 31, 2004, using rental revenues calculated on a straight-line basis in accordance with generally accepted accounting principles ("GAAP"). Annualized base rent does not include reimbursements for real estate taxes and insurance, common area and other operating expenses, substantially all of which are borne by the tenants in the case of triple net leases.

The bankruptcy or insolvency of a major tenant may also adversely affect the income produced by a property. If any of our tenants becomes a debtor in a case under the U.S. Bankruptcy Code, we cannot evict that tenant solely because of its bankruptcy. The bankruptcy court may authorize the tenant to reject and terminate its lease with us. Our claim against such a tenant for unpaid future rent would be subject to a statutory limitation that might be substantially less than the remaining rent actually owed to us under the tenant's lease. Any shortfall in rent payments could adversely affect our cash flow and our ability to make distributions to our stockholders.

Our U.S. Government Tenants May Not Receive Annual Appropriations, Which Could Adversely Affect Their Ability to Pay Us

U.S. government tenants may be subject to annual appropriations. If one of our U.S. government tenants fails to receive its annual appropriation, it might not be able to make its lease payments to us. In addition, defaults under leases with federal government tenants are governed by federal statute and not by state eviction or rent deficiency laws. All of our leases with U.S. government tenants provide that the government tenant may terminate the lease under certain circumstances. As of December 31, 2004, leases with U.S. government tenants at our properties accounted for approximately 4.2% of our aggregate annualized base rent.

Loss of a Tenant Could Have a Negative Impact on Our Business

A tenant may not renew its lease upon the expiration of the initial term. In addition, we may not be able to locate a qualified replacement tenant upon expiration or termination of a lease. Consequently, we could lose the cash flow from the affected property, which could negatively impact our business. We may have to divert cash flow generated by other properties to meet our mortgage payments, if any, or to pay other expenses related to owning the affected property. As of December 31, 2004, leases at our properties representing approximately 6.4% and 11.8% of the total square footage of our properties were scheduled to expire in 2005 and 2006, respectively.

Poor Economic Conditions in Our Markets Could Adversely Affect Our Business

Our properties are located only in the following markets:

As a result of our geographic concentration, we depend upon the local economic conditions in these markets, including local real estate conditions. We are, therefore, subject to increased exposure (positive or negative) to economic and other competitive factors specific to markets in confined geographic areas. Our operations may also be affected if too many competing properties are built in any of these markets. An economic downturn in any of these markets could adversely affect our operations and our ability to make distributions to stockholders. We cannot assure you that these markets will continue to grow or will remain favorable to the life science industry.

We May Have Difficulty Managing Our Growth

We expect to continue to grow by acquiring, redeveloping and selectively developing additional properties. To manage our growth effectively, we must successfully integrate new properties into our existing operations. We may not succeed with the integration. In addition, we may not effectively manage new properties, and new properties may not perform as expected. Our business could be adversely affected if we are unsuccessful in managing our growth.

Our Debt Service Obligations May Have Adverse Consequences on Our Business Operations

We use debt to finance our operations, including acquisitions of properties. Our use of debt may have adverse consequences, including the following:

As of December 31, 2004, we had outstanding mortgage indebtedness of approximately $639.0 million, secured by 54 properties and seven land development parcels, and outstanding debt under our unsecured line of credit and unsecured term loan of $548.0 million.

Our Unsecured Line of Credit and Unsecured Term Loan Restrict Our Ability to Engage in Some Business Activities

Our unsecured line of credit and unsecured term loan facilities contain customary negative covenants and other financial and operating covenants that, among other things:

These restrictions could cause us to default on our unsecured line of credit and unsecured term loan or negatively affect our operations and our ability to make distributions to our stockholders.

We May Not Be Able to Obtain Additional Capital to Further Our Business Objectives

Our ability to acquire, redevelop or develop properties depends upon our ability to obtain capital. Periodically, the real estate industry experiences reduced supplies of favorably-priced equity or debt capital, which decreases the level of new investment activity by publicly-traded real estate companies. A prolonged period in which we cannot effectively access the public equity or debt markets may result in heavier reliance on alternative financing sources to undertake new investments. An inability to obtain equity or debt capital on acceptable terms could delay or prevent us from acquiring, structuring and completing desirable investments, which could adversely affect our business. Also, the issuance of additional shares of capital stock or interests in subsidiaries to fund future operations could dilute the ownership of then existing stockholders.

We have filed a "shelf" registration statement on Form S-3, under which we may offer from time to time and at our discretion, common stock, preferred stock, warrants and debt securities with an aggregate public offering price of up to $500,000,000, in amounts, at prices and on terms to be determined at the time of offering.

If Interest Rates Rise, Our Debt Service Costs Will Increase

Borrowings outstanding under our unsecured line of credit, unsecured term loan and certain other borrowings bear interest at a variable rate, and we may incur additional variable rate debt in the future. Increases in market interest rates would increase our interest expense under these debt instruments and would increase the costs of refinancing existing indebtedness or obtaining new debt. Accordingly, these increases could adversely affect our financial position and our ability to make distributions to stockholders.

We May Not Be Able to Acquire Properties or Operate Them Successfully

Our success depends in large part upon our ability to acquire additional properties on satisfactory terms and to operate them successfully. If we are unable to do so, our business could be adversely affected. In addition, the acquisition of life science properties generally involves a higher per square foot price than the acquisition of traditional suburban office properties.

The acquisition, ownership and operation of real estate is subject to many risks that may adversely affect our business and our ability to make payments to stockholders, including the risks that:

If we encounter any of these risks, our business and our ability to make payments to stockholders could be adversely affected.

We May Not Be Able to Complete Redevelopment and Development Projects Effectively

Our redevelopment and development activities subject us to many risks, including those associated with:

In addition, redevelopment and development activities, regardless of whether they are ultimately successful, typically require a substantial portion of management's time and attention. This may distract management from focusing on other operational activities. If we are unable to complete redevelopment and development projects successfully, our business may be adversely affected.

If Our Revenues Are Less Than Our Expenses, We May Have to Borrow Additional Funds and We May Not Be Able to Make Distributions to Our Stockholders

If our properties do not generate revenues sufficient to meet our operating expenses, including debt service and other capital expenditures, we may have to borrow additional amounts to cover fixed costs and cash flow needs. This could adversely affect our ability to make distributions to our stockholders. Factors that could adversely affect the revenues from, and the value of, our properties include:

In addition, if a lease at a property is not a triple net lease, we will have greater expenses associated with that property and greater exposure to increases in such expenses. Significant expenditures, such as mortgage payments, real estate taxes, insurance and maintenance costs, generally are fixed and do not decrease when revenues at the related property decrease.

Improvements to Life Science Properties Are More Costly Than Traditional Office Space

Our properties contain generic infrastructure improvements that are more costly than other property types. Although we have historically been able to recover the additional investment in generic infrastructure improvements through higher rental rates, there is the risk that we will not be able to continue to do so in the future. Typical improvements include:

We May Not Be Able to Sell Our Properties Quickly to Raise Money

Investments in real estate are relatively illiquid. Accordingly, we may not be able to sell our properties when we desire or at acceptable prices in response to changes in economic or other conditions. In addition, the Internal Revenue Code limits our ability to sell properties held for fewer than four years. These limitations on our ability to sell our properties may adversely affect our cash flows and our ability to make distributions to stockholders.

We Face Substantial Competition in Our Target Markets

The significant competition for business in our target markets could have an adverse effect on our operations. We compete for investment opportunities with:

Many of these entities have substantially greater financial resources than we do and may be able to accept more risk than we are willing to accept. These entities may be less sensitive to risks with respect to the creditworthiness of a tenant or the geographic concentration of their investments. Competition may also reduce the number of suitable investment opportunities available to us or may increase the bargaining power of property owners seeking to sell.

Our Properties May Have Defects That Are Unknown to Us

Although we review the physical condition of our properties before they are acquired, and on a periodic basis after acquisition, any of our properties may have characteristics or deficiencies unknown to us that could adversely affect the property's value or revenue potential.

If We Fail to Qualify as a REIT, We Would Be Taxed at Corporate Rates and Would Not Be Able to Take Certain Deductions When Computing Our Taxable Income

If, in any taxable year, we fail to qualify as a REIT:

As a result of any additional tax liability, we might need to borrow funds or liquidate certain investments in order to pay the applicable tax. Accordingly, funds available for investment or distribution to our stockholders would be reduced for each of the years involved.

Qualification as a REIT involves the application of highly technical and complex provisions of the Internal Revenue Code to our operations and financial results, and the determination of various factual matters and circumstances not entirely within our control. There are only limited judicial or administrative interpretations of these provisions. Although we believe that we have operated, commencing with our taxable year ended December 31, 1996, in a manner so as to qualify as a REIT, we cannot assure you that we are or will remain so qualified.

In addition, although we are not aware of any pending tax legislation that would adversely affect our ability to operate as a REIT, new legislation, regulations, administrative interpretations or court decisions could change the tax laws or interpretations of the tax laws regarding qualification as a REIT, or the federal income tax consequences of that qualification, in a manner that is adverse to our stockholders.

There Are Limits on the Ownership of Our Capital Stock Under Which A Stockholder May Lose Beneficial Ownership of Its Shares

The Internal Revenue Code provides that, in order for us to maintain our qualification as a REIT, not more than 50% of the value of our outstanding capital stock may be owned, directly or constructively, by five or fewer individuals or entities.

In addition, our charter prohibits, with certain limited exceptions, direct or constructive ownership of shares of our capital stock representing more than 9.8% of the combined total value of the outstanding shares of our capital stock by any person (the "Ownership Limit"). Our Board of Directors may exempt a stockholder from the Ownership Limit if, prior to the exemption, our Board of Directors receives all information it deems necessary to determine or ensure our status as a REIT.

The constructive ownership rules are complex and may cause shares of our common stock owned directly or constructively by a group of related individuals or entities to be constructively owned by one individual or entity. A transfer of shares to a person who, as a result of the transfer, violates the Ownership Limit, may be void or may be deemed to be made to a trust, for the benefit of one or more qualified charitable organizations designated by us. In that case, the intended transferee will have only a right to share, to the extent of the transferee's original purchase price for such shares, in proceeds from the trust's sale of those shares.

In Addition to the Ownership Limit, Certain Provisions of Our Charter and Bylaws and Our Stockholder Rights Plan May Delay or Prevent Transactions That May Be Deemed to Be Desirable to Our Stockholders

As authorized by Maryland law, our charter allows our Board of Directors to cause us to issue additional authorized but unissued shares of our common stock or preferred stock and to classify or reclassify unissued shares of common or preferred stock without any stockholder approval. Our Board of Directors could establish a series of preferred stock that could delay, defer or prevent a transaction that might involve a premium price for our common stock or for other reasons be desired by our common stockholders or that have a dividend preference which may adversely affect our ability to pay dividends on our common stock.

Our charter permits the removal of a director only upon a two-thirds vote of the votes entitled to be cast generally in the election of directors and our bylaws require advance notice of a stockholder's intention to nominate directors or to present business for consideration by stockholders at an annual meeting of our stockholders. Our charter and bylaws also contain other provisions that may delay, defer or prevent a transaction or change in control that involves a premium price for our common stock or that for other reasons may be desired by our stockholders.

Under our Stockholder Rights Plan, if a stockholder acquires beneficial ownership of 15% or more of our common stock, other stockholders would become entitled to purchase our common stock at half the market price, which would likely result in substantial dilution to the 15% or greater stockholder. This may also have the effect of delaying or preventing a change in control or other transaction that might involve a premium price for our common stock or for other reasons desired by our common stockholders.

Our Insurance May Not Adequately Cover All Potential Losses

If we experience a loss at any of our properties that is not covered by insurance or that exceeds our insurance policy limits, we could lose the capital invested in the affected property and, possibly, future revenues from that property. In addition, we could continue to be obligated on any mortgage indebtedness or other obligations related to the affected properties. We carry comprehensive liability, fire, extended coverage and rental loss insurance with respect to our properties. We have obtained earthquake insurance for all of our properties because many of them are located in the vicinity of active earthquake faults. We also carry environmental remediation insurance and have title insurance policies on all of our properties. We obtain our title insurance policies when we acquire the property, with each policy covering an amount equal to the initial purchase price of each property. Accordingly, any of our title insurance policies may be in an amount less than the current value of the related property.

We believe that our insurance policy specifications, insured limits and deductibles are consistent with or superior to those customarily carried for similar properties. Our tenants are also required to maintain comprehensive insurance, including liability and casualty insurance, that is customarily obtained for similar properties. There are, however, certain types of losses that we and our tenants do not generally insure against because they are uninsurable or because it is not economical to insure against them. In the current market, there have recently been substantial increases in the premium cost of property and liability insurance. The availability of coverage against certain types of losses, such as from terrorism or toxic mold, has become more limited and, when available, is at a significantly higher premium cost. We cannot predict whether insurance coverage against terrorism or toxic mold will remain available for our properties because insurance companies may no longer offer coverage against such losses or, if offered, such coverage may become prohibitively expensive. Most, but not all, of our properties are low-rise buildings in suburban areas. Toxic mold has not presented any material problems at any of our properties.

We Could Incur Significant Costs Complying With Environmental Laws

Federal, state and local environmental laws and regulations may require us, as a current or prior owner or operator of real estate, to investigate and clean up hazardous or toxic substances or petroleum products released at or from any of our properties. The cost of investigating and cleaning up contamination could be substantial and could exceed the amount of any environmental remediation insurance coverage available to us. In addition, the presence of contamination, or the failure to properly clean it up, may adversely affect our ability to lease or sell an affected property, or to borrow funds using that property as collateral.

Under environmental laws and regulations, we may have to pay governmental entities or third parties for property damage and for investigation and clean-up costs incurred by those parties relating to contaminated properties regardless of whether we knew of or caused the contamination. Even if more than one party may have been responsible for the contamination, we may be held responsible for all of the clean-up costs. In addition, third parties may sue us for damages and costs resulting from environmental contamination or jointly responsible parties may contest their responsibility or be financially unable to pay their share of such costs.

Environmental laws also govern the presence, maintenance and removal of asbestos-containing materials. These laws may impose fines and penalties on us for the release of asbestos-containing materials and may allow third parties to seek recovery from us for personal injury from exposure to asbestos fibers. We have detected asbestos-containing materials at some of our properties, but we do not expect that it will result in material environmental costs or liabilities to us.

Environmental laws and regulations also require the removal or upgrading of certain underground storage tanks and regulate:

Many of our tenants routinely handle hazardous substances and wastes as part of their operations at our properties. Environmental laws and regulations subject our tenants, and potentially us, to liability resulting from these activities. Environmental liabilities could also affect a tenant's ability to make rental payments to us. We require our tenants to comply with these environmental laws and regulations and to indemnify us for any related liabilities.

Independent environmental consultants have conducted Phase I or similar environmental assessments at all of our properties. We intend to use consultants to conduct similar environmental assessments on our future acquisitions. This type of assessment generally includes a site inspection, interviews and a public records review, but no subsurface sampling. These assessments and certain additional investigations of our properties have not to date revealed any environmental liability that we believe would have a material adverse effect on our business or results of operations.

The additional investigations included, as appropriate:

Nevertheless, it is possible that the assessments on our properties have not revealed, or that assessments on future acquisitions, will not reveal all environmental liabilities. Consequently, there may be material environmental liabilities of which we are unaware that may result in substantial costs to us or our tenants and that could have a material adverse effect on our business.

We May Incur Significant Costs Complying With the Americans With Disabilities Act and Similar Laws

Under the Americans With Disabilities Act, places of public accommodation and/or commercial facilities are required to meet federal requirements related to access and use by disabled persons. We may be required to make substantial capital expenditures at our properties to comply with this law. In addition, our noncompliance could result in the imposition of fines or an award of damages to private litigants.

A number of additional federal, state and local laws and regulations exist regarding access by disabled persons. These regulations may require modifications to our properties or may affect future renovations. This may limit the overall returns on our investments.

We believe that our properties are substantially in compliance with the present requirements of the Americans With Disabilities Act and similar laws.

We May Incur Significant Costs If We Fail to Comply With Laws or If Laws Change

Our properties are subject to many federal, state and local regulatory requirements and to state and local fire and life-safety requirements. If we do not comply with all of these requirements, we may have to pay fines to governmental authorities or damage awards to private litigants. We believe that our properties are currently in compliance with all of these regulatory requirements. We do not know whether these requirements will change or whether new requirements will be imposed. Changes in these regulatory requirements could require us to make significant unanticipated expenditures. These expenditures could have an adverse effect on us and our ability to make distributions to stockholders.

The Loss of Services of Any of Our Senior Executive Officers Could Adversely Affect Us

We depend upon the services of relatively few executive officers. The loss of services of any one of them may adversely affect our business, financial condition and prospects. We use the extensive personal and business relationships that members of our management have developed over time with owners of life science properties and with major life science industry tenants. We have employment agreements with all of our senior executive officers, but cannot assure you that they will remain employed with us.

We May Change Our Business Policies Without Stockholder Approval

Our Board of Directors determines all of our material business policies, with management's input, including those related to our:

Our Board of Directors may amend or revise these policies at any time without a vote of our stockholders. A change in these policies could adversely affect our business and our ability to make distributions to our stockholders.

We Could Become Highly Leveraged and Our Debt Service Obligations Could Increase

Our organizational documents do not limit the amount of debt that we may incur. Therefore, we could become highly leveraged. This would result in an increase in our debt service obligations that could adversely affect our cash flow and our ability to make distributions to our stockholders.

We have adopted a policy of incurring debt only if, upon such incurrence, our debt to total market capitalization ratio would not exceed 57.5%. Our total market capitalization is the market value of our capital stock, including interests exchangeable for shares of capital stock, plus total debt. Our Board of Directors could, however, change or eliminate this policy at any time. Higher leverage could also increase the risk of default on our debt obligations.

Our Distributions to Stockholders May Decline at Any Time

We may not continue our current level of distributions to stockholders. Our Board of Directors will determine future distributions based on a number of factors, including:

 

Possible Future Sales of Shares of Our Common Stock Could Adversely Affect Its Market Price

We cannot predict the effect, if any, of future sales of shares of our common stock on the market price of our common stock from time to time. Sales of substantial amounts of capital stock (including common stock issued upon the exercise of stock options), or the perception that such sales may occur, could adversely affect prevailing market prices for our common stock.

We have reserved for issuance to our officers, directors and employees pursuant to our Amended and Restated 1997 Stock Award and Incentive Plan that number of shares of our common stock that equals 12% of the total number of shares outstanding at any time, provided that in no event may the number of shares of our common stock available for issuance under the plan exceed 3,000,000 shares at any time.

As of December 31, 2004, options to purchase 607,331 shares of our common stock were outstanding, of which options to purchase 500,000 shares of our common stock were exercisable. We have filed a registration statement with respect to the issuance of shares of our common stock pursuant to grants under our equity incentive plan. In addition, any shares issued under our equity incentive plan will be available for sale in the public market from time to time without restriction by persons who are not our "affiliates" (as defined in Rule 144 adopted under the Securities Act of 1933). Affiliates will be able to sell shares of our common stock pursuant to exemptions from registration requirements or upon registration.

External Factors May Adversely Impact the Valuation of Investments

We hold equity investments in certain publicly-traded companies and privately held entities primarily involved in the life science industry. The valuation of these investments is affected by many external factors beyond our control, including, but not limited to, market prices, market conditions, prospects for favorable or unfavorable clinical trial results, new product initiatives and new collaborative agreements. Unfavorable developments with respect to any of these factors may have an adverse impact on the valuation of our investments.

Available Information

We will provide, upon request and free of charge, paper copies of our annual report on Form 10-K, quarterly reports on Form 10-Q and current reports on Form 8-K, including any amendments to the foregoing reports, as soon as is reasonably practicable after such material is electronically filed with, or furnished to, the Securities and Exchange Commission. These materials, along with our corporate governance guidelines, business integrity policy and board committee charters, are also available through our corporate website at http://www.labspace.com. The public may also download these materials from the Securities and Exchange Commission's website at http://www.sec.gov. Any amendments to, and waivers of, our business integrity policy will be posted on our corporate website.

Employees

As of December 31, 2004, we had 73 full-time employees. We believe that we have good relations with our employees. We have adopted a Business Integrity Policy that applies to, and is executed by, all of our employees.

Item 2. Properties

General.

Our properties, some of which consist of multiple facilities, range in size up to 284,000 square feet, are built to accommodate single or multiple tenants and are generally one or two story concrete tilt-up, block and/or steel frame structures. The exteriors typically resemble traditional suburban office properties, but interior infrastructures are designed to accommodate the needs of life science industry tenants. These improvements typically are generic to life science industry tenants rather than being specific to a particular tenant. As a result, we believe that the improvements have long-term value and utility and are usable by a wide range of life science industry tenants. Generic infrastructure improvements to our life science properties include:

We own a fee simple interest in each of our properties, except for the following ten properties that account for approximately 10% of the total rentable square footage of our properties:

As of December 31, 2004, we had 249 leases with a total of 213 tenants, and 64 of our 112 properties were single-tenant properties. Leases in our multi- tenant buildings typically have terms of three to seven years, while the single- tenant building leases typically have initial terms of 10 to 20 years. As of December 31, 2004:

Our leases also typically give us the right to review and approve tenant alterations to the property. Generally, tenant-installed improvements to the properties remain our property after termination of the lease at our election. However, we are permitted under the terms of most of our leases to require that the tenant, at its expense, remove the improvements and restore the premises to their original condition.

As of December 31, 2004, we managed all of our properties.

Location of Properties

The locations of our properties are diversified among a number of life science markets. The following table sets forth, as of December 31, 2004, the total rentable square footage, annualized base rent and encumbrances of our properties in each of our existing markets (dollars in thousands).

PART II

Item 5. Market for Registrant's Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities

Our common stock is traded on the New York Stock Exchange ("NYSE") under the symbol "ARE". On March 11, 2005, the last reported sales price per share of our common stock was $66.82, and there were approximately 239 holders of record of our common stock (excluding beneficial owners whose shares are held in the name of CEDE & Co.). The following table sets forth the quarterly high and low sales prices per share of our common stock as reported on the NYSE and the distributions paid by us with respect to each such period.

Future distributions on our common stock will be determined by and at the discretion of our Board of Directors and will be dependent upon a number of factors, including actual cash available for distribution, our financial condition and capital requirements, the annual distribution requirements under the REIT provisions of the Internal Revenue Code and such other factors as our Board of Directors deems relevant. To maintain our qualification as a REIT, we must make annual distributions to stockholders of at least 90% of our taxable income for the current taxable year, determined without regard to deductions for dividends paid and excluding any net capital gains. Under certain circumstances, we may be required to make distributions in excess of cash flow available for distributions to meet these distribution requirements. In such a case, we may borrow funds or may raise funds through the issuance of additional debt or equity capital. We cannot assure you that we will make any future distributions.

The tax treatment of distributions on common stock paid in 2004 is as follows: (1) 76.8% ordinary dividend, (2) 19.8% return of capital, (3) 2.4% capital gain at 15%, and (4) 1.0% Section 1250 capital gain at 25%. The tax treatment of distributions paid in 2003 is as follows: (1) 87.5% ordinary dividend, (2) 3.0% return of capital, (3) 1.7% capital gain at 15%, and (4) 7.8% Section 1250 capital gain at 25%,

  2. During the second quarter of 2004, we elected to redeem the 9.50% Series A cumulative redeemable preferred stock ("Series A preferred stock"). Accordingly, in compliance with Emerging Issues Task Force Topic D-42, we recorded a charge of $1,876,000, or $0.10 per common share (diluted) in the second quarter of 2004 for costs related to the redemption of the Series A preferred stock.

Gain/loss on sales of property is included in the income statement in income from discontinued operations, net.
  4. 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 miscorrelation between real estate values and historical cost accounting for real estate assets, the Board of Governors of the National Association of Real Estate Investment Trusts ("NAREIT") established the measurement tool of Funds From Operations ("FFO"). Since its introduction, FFO has become a widely used non-GAAP financial measure by 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. In 2003, NAREIT issued guidance, which modifies the calculation of FFO for both past and future periods. In accordance with NAREIT's revised guidance, we now include losses from early extinguishment of debt and real estate impairment charges in our calculation of FFO. As such, the reported amounts of FFO for the year ended December 31, 2002 have been modified from those previously reported. The White Paper defines FFO as net income (loss) (computed in accordance with GAAP), excluding gains (or losses) from sales, plus real estate depreciation and amortization, and after adjustments for unconsolidated partnerships and joint ventures. While FFO is a relevant and widely used measure of operating performance for REITs, it 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. We believe that net income is the most directly comparable GAAP financial measure to FFO. For a more detailed discussion of FFO, see "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations - Funds from Operations."

Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations

The terms "Company", "we", "our" and "us" as used in this Form 10-K refer to Alexandria Real Estate Equities, Inc. and its subsidiaries. The following discussion should be read in conjunction with our consolidated financial statements and notes thereto appearing elsewhere in this Form 10-K.

Overview

The following factors, among others, could cause actual results and future events to differ from those set forth or contemplated in the forward-looking statements:

  • Changes in general economic conditions or in the real estate and life science industries;
  • Risks and uncertainties related to how successful our tenants are in discovering, developing, making or selling their products and technologies;
  • Potential liability for damages resulting from our tenant's use of hazardous materials;
  • Adverse changes in the annual appropriations received by our government tenants;
  • Economic conditions in our markets could adversely affect our business;
  • Loss of a tenant could have a negative impact on our business;
  • We may have difficulty managing our growth;
  • Our debt service obligations may have adverse consequences on our business operations;
  • Our unsecured line of credit and unsecured term loan restrict our ability to engage in some business activities;
  • Ability to obtain additional capital to further our business objectives;
  • Difficulties in identifying properties for acquisition or operating them successfully;
  • Risks associated with completing developments and redevelopments;
  • Our failure to qualify and maintain our status as a real estate investment trust under the Internal Revenue Code of 1986;
  • Losses in excess of our insurance coverage;
  • Environmental uncertainties;
  • Failure to comply with laws, including the Americans with Disabilities Act and similar laws; and
  • Ability to retain our senior executives.

Our success also depends upon economic trends generally and various market conditions. We caution you not to place undue reliance on forward-looking statements, which reflect our analysis only and speak as of the date of this report or, if different, as of the dates indicated in the statements. We assume no obligation to update or supplement forward-looking statements.

We are a publicly-traded real estate investment trust focused primarily on the ownership, operation, management, acquisition, expansion and selective redevelopment and development of high quality, strategically located properties containing office/laboratory space leased principally to tenants in the life science industry. We refer to these properties as "life science properties".

In 2004, we:

  • Acquired 23 properties with an aggregate of approximately 1,630,000 rentable square feet. In addition, we completed the development of a property with an aggregate of approximately 104,000 rentable square feet.
  • Expanded our unsecured line of credit from $440 million to $500 million and extended its term to December 2007, which may be further extended at our sole option for an additional one-year period.
  • Expanded our unsecured term loan from $150 million to $250 million and extended its term to December 2009.
  • Sold one property with approximately 42,000 rentable square feet.
  • Completed a public offering of 5,185,500 shares of our 8.375% Series C cumulative redeemable preferred stock ("Series C preferred stock").
  • Redeemed all of the outstanding shares of our 9.50% Series A cumulative preferred stock with proceeds from the Series C preferred stock offering.

Our primary source of revenue is rental income and tenant recoveries from leases at the properties we own. Of the 112 properties we owned as of December 31, 2004, four were acquired in 1994, nine in 1996, nine in 1997, 26 in 1998, six in 1999, 11 in 2000, five in 2001, four in 2002, four in 2003 (the "2003 Properties") and 23 in 2004. In addition, we completed the development of one property in 1999, five properties in 2000 (together with the 11 properties acquired in 2000, the "2000 Properties"), two properties in 2001 (together with the five properties acquired in 2001, the "2001 Properties"), two properties in 2002 (together with the four properties acquired in 2002, the "2002 Properties") and one property in 2004 (together with the 23 properties acquired in 2004, the "2004 Properties"). As a result of these acquisition and development activities, as well as our ongoing leasing and redevelopment activities, there have been significant increases in total revenues and expenses, including significant increases in total revenues and expenses for 2004 as compared to 2003, and for 2003 as compared to 2002.

Critical Accounting Policies

Our discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States ("GAAP"). Our significant accounting policies are described in the notes to our consolidated financial statements. The preparation of these financial statements in conformity with GAAP requires us to make estimates, judgments and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses. We base these estimates, judgments and assumptions on historical experience and on various other factors that we believe to be reasonable under the circumstances. Actual results may differ from these estimates under different assumptions or conditions.

REIT Compliance

We have elected to be taxed as a real estate investment trust ("REIT") under the Internal Revenue Code. Qualification as a REIT involves the application of highly technical and complex provisions of the Internal Revenue Code to our operations and financial results, and the determination of various factual matters and circumstances not entirely within our control. We believe that our current organization and method of operation comply with the rules and regulations promulgated under the Internal Revenue Code to enable us to qualify, and continue to qualify, as a REIT. However, it is possible that we have been organized or have operated in a manner that would not allow us to qualify as a REIT, or that our future operations could cause us to fail to qualify.

If we fail to qualify as a REIT in any taxable year, then we will be required to pay federal income tax (including any applicable alternative minimum tax) on our taxable income at regular corporate rates. If we lose our REIT status, then our net earnings available for investment or distribution to stockholders would be significantly reduced for each of the years involved and we would no longer be required to make distributions to our stockholders.

Rental Properties and Properties Under Development

In accordance with Statement of Financial Accounting Standards No. 141, "Business Combinations", we perform the following procedures when making an allocation of the purchase price of real estate: (1) estimate the value of the real estate as of the acquisition date on an "as if vacant" basis; (2) allocate the "as if vacant" value among land, land improvements, buildings, building improvements, tenant improvements and equipment; (3) calculate the value of the intangibles as the difference between the "as if vacant" value and the purchase price; and (4) allocate the intangible value to above, below and at market leases, origination costs associated with in-place leases, tenant relationships and other intangible assets.

The values allocated to land improvements, buildings, building improvements, tenant improvements and equipment are depreciated on a straight-line basis using an estimated life of 20 years for land improvements, 40 years for buildings and building improvements, the respective lease term for tenant improvements and the estimated useful life for equipment. The values of above and below market leases are amortized over the life of the related lease and recorded as either an increase (for below market leases) or a decrease (for above market leases) to rental income. The values of at-market leases and origination costs are classified as leasing costs, included in other assets on our balance sheets and amortized over the remaining life of the lease.

Rental properties and properties under development are individually evaluated for impairment when conditions exist which may indicate that it is probable that the sum of expected future undiscounted cash flows is less than the carrying amount of the property. Upon determination that impairment has occurred, a write-down is recorded to reduce the carrying amount of the property to its estimated fair value.

Capitalization of Costs

In accordance with Statement of Financial Accounting Standards No. 34, "Capitalization of Interest Cost" ("SFAS 34") and Statement of Financial Accounting Standards No. 67, "Accounting for Costs and Initial Rental Operations of Real Estate Projects" ("SFAS 67"), we capitalize direct construction and development costs, including predevelopment costs, interest, property taxes, insurance and other costs directly related and essential to the acquisition, development or construction of a project. Pursuant to SFAS 34 and SFAS 67, capitalization of construction and development costs is required while activities are ongoing to prepare an asset for its intended use. Costs incurred after a project is substantially complete and ready for its intended use are expensed as incurred. Costs previously capitalized related to abandoned acquisition or development opportunities are written-off. Should development activity cease, a portion of interest, property taxes, insurance and certain costs would no longer be eligible for capitalization, and would be expensed as incurred. Expenditures for repairs and maintenance are expensed as incurred.

We also capitalize costs directly related and essential to our leasing activities. These costs are amortized on a straight-line basis over the terms of the related leases. Costs that were previously capitalized and which related to unsuccessful leasing opportunities are written-off.

Accounting for Investments

We hold equity investments in certain publicly-traded companies and privately held entities primarily involved in the life science industry. All of our investments in publicly-traded companies are considered "available for sale" in accordance with Statement of Financial Accounting Standards No. 115, "Accounting for Certain Investments in Debt and Equity Securities" ("SFAS 115"), and are recorded at fair value. Fair value has been determined as the closing trading price at the balance sheet date, with unrealized gains and losses shown as a separate component of stockholders' equity. The classification of investments under SFAS 115 is determined at the time each investment is made, and such determination is reevaluated at each balance sheet date. The cost of investments sold is determined by the specific identification method, with net realized gains included in other income.

Investments in privately held entities are generally accounted for under the cost method because we do not influence any operating or financial policies of the entities in which we invest. Certain investments are accounted for under the equity method in accordance with Accounting Principles Board Opinion No. 18, "The Equity Method of Accounting for Investments in Common Stock" and Emerging Issues Task Force Topic D-46, "Accounting for Limited Partnership Investments". Under the equity method of accounting, we record our investment initially at cost and adjust the carrying amount of the investment to recognize our share of the earnings or losses of the investee subsequent to the date of our investment.

For all of our investments, if a decline in the fair value of an investment below its carrying value is determined to be other than temporary, such investment is written-down to its estimated fair value with a non-cash charge to current earnings. The factors that we consider in making these assessments include, but are not limited to, market prices, market conditions, financial condition, prospects for favorable or unfavorable clinical trial results, new product initiatives and/or sales, and new collaborative agreements.

Interest Rate Swap Agreements

We utilize interest rate swap agreements to hedge a portion of our exposure to variable interest rates associated with our unsecured line of credit and unsecured term loan. These agreements involve an exchange of fixed and floating interest payments without the exchange of the underlying principal amount (the "notional amount"). Interest received under all of our swap agreements is based on the one-month LIBOR rate. The net difference between the interest paid and the interest received is reflected as an adjustment to interest expense.

We reflect our interest rate swap agreements on the balance sheet at their estimated fair values. We use a variety of methods and assumptions based on market conditions and risks existing at each balance sheet date to determine the fair values of our interest rate swap agreements. These methods of assessing fair value result in a general approximation of value, and such value may never be realized.

All of our interest rate swap agreements meet the criteria to be deemed "highly effective" under the provisions of Statement of Financial Accounting Standards No. 133, "Accounting for Derivative Instruments and Hedging Activities" in reducing our exposure to variable interest rates. Accordingly, we have categorized these instruments as cash flow hedges. While we intend to continue to meet the conditions for such hedge accounting, if hedges did not qualify as "highly effective", the changes in the fair value of the derivatives used as hedges would be reflected in earnings.

We do not believe we are exposed to more than a nominal amount of credit risk in our interest rate swap agreements as our counterparties are established, well-capitalized financial institutions.

Recognition of Rental Income

Rental income from leases with scheduled rent increases, free rent and other rent adjustments is recognized on a straight-line basis over the respective lease terms. We include amounts currently recognized as income, and expected to be received in later years, in deferred rent in the accompanying consolidated balance sheets. Amounts received currently, but recognized as income in future years, are included as unearned rent in accounts payable, accrued expenses and tenant security deposits in the accompanying consolidated balance sheets. Tenant recoveries related to reimbursement of real estate taxes, insurance, repairs and maintenance, and other operating expenses are recognized as revenue in the period the applicable expenses are incurred.

We maintain an allowance for estimated losses that may result from the inability of our tenants to make required payments. If a tenant fails to make contractual payments beyond any allowance, we may recognize additional bad debt expense in future periods equal to the amount of unpaid rent and deferred rent.

Discontinued Operations

We follow the provisions of Statement of Financial Accounting Standards No. 144, "Accounting for the Impairment or Disposal of Long-Lived Assets" in determining whether a property qualifies as an asset "held for sale" and should be classified as "discontinued operations". A property is classified as "held for sale" when all of the following criteria for a plan of sale have been met: (1) management, having the authority to approve the action, commits to a plan to sell the property; (2) the property is available for immediate sale in its present condition, subject only to the terms that are usual and customary; (3) an active program to locate a buyer, and other actions required to complete the plan to sell, have been initiated; (4) the sale of the property is probable and is expected to be completed within one year; (5) the property is being actively marketed for sale at a price that is reasonable in relation to its current fair value; and (6) actions necessary to complete the plan of sale indicate that it is unlikely that significant changes to the plan will be made or that the plan will be withdrawn. When all of these criteria have been met, the property is classified as "held for sale" and its operations are classified as discontinued operations in our consolidated statements of income. When a property is designated as "held for sale", amounts for all prior periods presented are reclassified from continuing operations to discontinued operations. A loss is recognized for any initial adjustment of the asset's carrying amount to fair value less costs to sell in the period the asset qualifies as "held for sale". Depreciation of assets is discontinued commencing on the date they are designated as "held for sale".

Results of Operations

Comparison of the Year Ended December 31, 2004 to the Year Ended December 31, 2003

Rental revenues increased by $17.5 million, or 14%, to $143.9 million for 2004 compared to $126.4 million for 2003. The increase resulted primarily from the 2003 Properties being owned for a full year and the addition of the 2004 Properties. Rental revenues from properties operating for a full year during 2004 and 2003 (the "2004 Same Properties") increased by $2.2 million, or 2.2%, primarily due to increases in rental rates and a slight increase in occupancy. The average occupancy level of the 2004 Same Properties was 97.1% as of December 31, 2004, compared to 96.6% as of December 31, 2003.

Tenant recoveries increased by $3.8 million, or 12%, to $35.9 million for 2004 compared to $32.1 million for 2003. The increase resulted primarily from the 2003 Properties being owned for a full year and the addition of the 2004 Properties. Tenant recoveries for the 2004 Same Properties increased by $575,000, or 2.3%, primarily due to increases in certain recoverable operating expenses during 2004.

Other income increased by $1.5 million, or 71%, to $3.5 million for 2004 compared to $2.1 million for 2003, primarily due to an increase in realized gains on investments and from a general increase in miscellaneous sources of income.

Rental operating expenses increased by $5.6 million, or 17%, to $38.4 million for 2004 compared to $32.8 million for 2003. The increase resulted primarily from the 2003 Properties being owned for a full year and the addition of the 2004 Properties. Operating expenses for the 2004 Same Properties increased by $398,000, or 1.6%, primarily due to increases in salaries for property engineers, property taxes and repair and maintenance expenses offset slightly by a decrease in property insurance expenses (substantially all of which are recoverable from our tenants through tenant recoveries).

General and administrative expenses increased by $894,000, or 6%, to $15.1 million for 2004 compared to $14.2 million for 2003, mainly due to compliance with Section 404 of the Sarbanes-Oxley Act, Operation Outreach and general increases in administrative costs. Our Operation Outreach program provides financial assistance to families of activated and deployed soldiers that faced significant financial challenges and had significant financial needs.

Interest expense increased by $2.3 million, or 9%, to $28.7 million for 2004 compared to $26.4 million for 2003. The increase resulted primarily from increases in indebtedness on our unsecured line of credit, unsecured term loan and secured notes payable, and to increases in the floating interest rates on our unsecured line of credit and unsecured term loan. These borrowings were utilized to finance the acquisition of the 2003 and 2004 Properties, and the development and redevelopment of properties. The weighted average effective interest rate on these borrowings (not including the effect of interest rate swap agreements) increased from 2.64% as of December 31, 2003 to 3.72% as of December 31, 2004. We have entered into certain swap agreements to hedge a portion of exposure to variable interest rates with our unsecured line of credit and unsecured term loan (see "Liquidity and Capital Resources - Unsecured Line of Credit and Unsecured Term Loan").

Depreciation and amortization increased by $3.9 million, or 10%, to $42.5 million for 2004 compared to $38.6 million for 2003. The increase resulted primarily from depreciation associated with the 2003 Properties being owned for a full year and the addition of the 2004 Properties.

Income from discontinued operations of $1.6 million for 2004 reflects the results of operations of one property that was designated as "held for sale" as of December 31, 2003. In connection with this sale, we recorded a gain of approximately $1.6 million during 2004. Income from discontinued operations of $11.1 million for 2003 reflects the results of operations of three properties that were designated as "held for sale" as of December 31, 2002. In connection with the sale of these properties, we recorded a net gain of approximately $8.3 million during 2003.

Comparison of the Year Ended December 31, 2003 to the Year Ended December 31, 2002

Rental revenues increased by $14.7 million, or 13%, to $126.4 million for 2003 compared to $111.7 million for 2002. The increase resulted primarily from the 2002 Properties being owned for a full year and the addition of the 2003 Properties. Rental revenues from properties operating for a full year during 2003 and 2002 (the "2003 Same Properties") increased by $1.7 million, or 2.1%, due to increases in rental rates and offset by a slight decrease in occupancy. The average occupancy level of the 2003 Same Properties was 96.7% as of December 31, 2003, compared to 97.2% as of December 31, 2002.

Tenant recoveries increased by $3.1 million, or 11%, to $32.1 million for 2003 compared to $29.0 million for 2002. The increase resulted primarily from the 2002 Properties being owned for a full year and the addition of the 2003 Properties. Tenant recoveries for the 2003 Same Properties increased by $659,000, or 2.9%, primarily due to increases in certain recoverable operating expenses.

Other income increased by $511,000, or 33%, to $2.1 million for 2003 compared to $1.6 million for 2002, primarily due to an increase in realized gains on investments and from a general increase in miscellaneous sources of income.

Rental operating expenses increased by $3.7 million, or 13%, to $32.8 million for 2003 compared to $29.1 million for 2002. The increase resulted primarily from the 2002 Properties being owned for a full year and the addition of the 2003 Properties. Operating expenses for the 2003 Same Properties increased by $871,000, or 4.1%, primarily due to an increase in property insurance and property taxes (substantially all of which are recoverable from our tenants through tenant recoveries).

General and administrative expenses increased by $775,000, or 6%, to $14.2 million for 2003 compared to $13.4 million for 2002, mainly due to general increases in administrative costs, primarily payroll and related expenses.

Interest expense increased by $1.4 million, or 6%, to $26.4 million for 2003 compared to $25.0 million for 2002. The increase resulted primarily from an increase in indebtedness on our unsecured line of credit, unsecured term loan and secured notes payable. These borrowings were utilized to finance the acquisition of the 2002 and 2003 Properties and the development and redevelopment of properties. The increase in interest expense was partially offset by a decrease in the floating interest rate on our unsecured line of credit and unsecured term loan. The weighted average effective interest rate on these borrowings (not including the effect of interest rate swap agreements) decreased from 3.07% as of December 31, 2002 to 2.64% as of December 31, 2003. We have entered into certain swap agreements to hedge a portion of exposure to variable interest rates with our unsecured line of credit and unsecured term loan (see "Liquidity and Capital Resources - Unsecured Line of Credit and Unsecured Term Loan").

Depreciation and amortization increased by $5.7 million, or 17%, to $38.6 million for 2003 compared to $32.9 million for 2002. The increase resulted primarily from depreciation associated with the 2002 Properties being owned for a full year and the addition of the 2003 Properties.

Income from discontinued operations of $11.1 million for 2003 reflects the results of operations of three properties that were designated as "held for sale" as of December 31, 2002. In connection with the sale of these properties, we recorded a net gain of approximately $8.3 million during 2003. Income from discontinued operations of $1.8 million for 2002 reflects the results of operations of four properties that have been designated as "held for sale". In connection with these prospective sales, we recorded a non-cash impairment charge of $1,150,000 related to a property in the San Francisco Bay market that could not be redeveloped pursuant to its original strategic objectives. This charge has been included in income from discontinued operations for 2002.

Liquidity and Capital Resources

Cash Flows

Net cash provided by operating activities for 2004 decreased by $7.1 million to $67.8 million compared to $74.8 million for 2003. An increase in cash flows from our portfolio of operating properties was offset by a decrease in net cash provided by operating activities primarily from changes in operating assets (tenant security deposits and other restricted cash, deferred rent and other assets).

Net cash used in investing activities for 2004 increased by $310.9 million to $450.7 million compared to $139.8 million for 2003. This increase was primarily due to an increase in property acquisitions, increases in additions to rental properties and properties under development, and a decrease in proceeds from sales of rental properties.

Net cash provided by financing activities for 2004 increased by $315.0 million to $381.1 million compared to $66.2 million for 2003. This increase was primarily due to the net proceeds from our Series C preferred stock offering, increases in borrowings from our unsecured line of credit and unsecured term loan, and an increase in proceeds from secured notes payable. This was partially offset by the redemption of our Series A cumulative redeemable preferred stock.

  1. The weighted average interest rate is calculated based on the outstanding debt as of January 1st of each year.

Unsecured Line of Credit and Unsecured Term Loan

In December 2004, we amended our unsecured line of credit to increase our borrowing capacity from $440 million to $500 million. Borrowings under our unsecured line of credit, as amended, bear interest at a floating rate based on our election of either a LIBOR-based rate or the higher of the bank's reference rate and the Federal Funds rate, plus 0.5%. For each LIBOR-based advance, we must elect a LIBOR period of one, two, three or six months. The unsecured line of credit expires December 2007 and may be extended at our sole option for an additional one-year period. As of December 31, 2004, we had borrowings of $298.0 million outstanding on the unsecured line of credit with a weighted average interest rate of 3.72%.

In December 2004, we amended our unsecured term loan to increase the loan from $150 million to $250 million. The unsecured term loan bears interest at a floating rate based on our election of either a LIBOR-based rate or the higher of the bank's reference rate and the Federal Funds rate, plus 0.5%. For each LIBOR-based advance, we must elect to fix for a period of one, two three or six months. The unsecured term loan expires in December 2009. As of December 31, 2004, we had borrowings of $250.0 million outstanding on the unsecured term loan with a weighted average interest rate of 3.72%.

Our unsecured line of credit and unsecured term loan contain financial covenants, including, among other things, maintenance of minimum net worth, a leverage ratio and a fixed charge coverage ratio. In addition, the terms of the unsecured line of credit and unsecured term loan restrict, among other things, certain investments, indebtedness, distributions and mergers.

Aggregate borrowings under the unsecured line of credit and unsecured term loan may be limited to an amount based on the net operating income derived from a pool of unencumbered properties. Accordingly, as we acquire or complete the development or redevelopment of additional unencumbered properties, aggregate borrowings available under the unsecured line of credit and unsecured term loan will increase up to a maximum combined amount of $750 million. Under these provisions as of December 31, 2004, aggregate borrowings under our unsecured line of credit and unsecured term loan were limited to $666 million. Under the amended and restated unsecured line of credit and unsecured term loan, we have an option to increase our maximum available commitment by an additional $100 million.

We utilize interest rate swap agreements to hedge a portion of our exposure to variable interest rates associated with our unsecured line of credit and unsecured term loan. These agreements involve an exchange of fixed and floating interest payments without the exchange of the underlying principal amount (the "notional amount"). Interest received under all of our swap agreements is based on the one-month LIBOR rate. The net difference between the interest paid and the interest received is reflected as an adjustment to interest expense.

The following table summarizes our interest rate swap agreements as of December 31, 2004 (dollars in thousands):

   Effect at December 31, 2004                 =================                                 ========





We do not believe we are exposed to more than a nominal amount of credit risk in our interest rate swap agreements as our counterparties are established, well-capitalized financial institutions. In addition, we have entered into master derivative agreements with each counterparty. These master derivative agreements (all of which are on the standard International Swaps & Derivatives Association, Inc. form) define certain terms between us and each counterparty to address and minimize certain risks associated with our swap agreements, including a default by a counterparty.

As of December 31, 2004 and 2003, our interest rate swap agreements have been classified at their fair values of approximately $2.1 million and $6.3 million, respectively, in accounts payable, accrued expenses and tenant security deposits in our consolidated balance sheets. The offsetting adjustments of $2.1 million and $6.3 million, respectively, were reflected as deferred losses in accumulated other comprehensive income (loss) in the stockholders' equity section of our consolidated balance sheets. Balances in accumulated other comprehensive income (loss) are recognized in earnings as swap payments are made.

Other Resources and Liquidity Requirements

In June 2004, we completed a public offering of 5,185,500 shares of our 8.375% Series C cumulative redeemable preferred stock (including the shares issued upon exercise of the underwriters' over-allotment option). The shares were issued at a price of $25.00 per share, resulting in aggregate proceeds of approximately $124.0 million (after deducting underwriters' discounts and other offering costs).

In December 2004, we amended and restated our existing unsecured line of credit and unsecured term loan. The maximum permitted borrowings under the unsecured line of credit and unsecured term loan increased to $500 million and $250 million, respectively. We may in the future elect to increase commitments under the unsecured line of credit by up to an additional $100 million.

We expect to continue meeting our short-term liquidity and capital requirements generally through our working capital and net cash provided by operating activities. We believe that the net cash provided by operating activities will continue to be sufficient to enable us to make distributions necessary to continue qualifying as a REIT. We also believe that net cash provided by operating activities will be sufficient to fund recurring non- revenue enhancing capital expenditures, tenant improvements and leasing commissions.

We expect to meet certain long-term liquidity requirements, such as for property acquisitions, property development and redevelopment activities, scheduled debt maturities, expansions and other non-recurring capital improvements, through net cash provided by operating activities, long-term secured and unsecured indebtedness, including borrowings under the unsecured line of credit and unsecured term loan, and the issuance of additional debt and/or equity securities.

Exposure to Environmental Liabilities

In connection with the acquisition of all of our properties, we have obtained Phase I environmental assessments to ascertain the existence of any environmental liabilities or other issues. The Phase I environmental assessments of our properties have not revealed any environmental liabilities that we believe would have a material adverse effect on our financial condition or results of operations taken as a whole, nor are we aware of any material environmental liabilities that have occurred since the Phase I environmental assessments were completed. In addition, we carry a policy of pollution legal liability insurance covering exposure to certain environmental losses at all of our properties.

Capital Expenditures, Tenant Improvements and Leasing Costs

The following table shows total and weighted average per square foot property-related capital expenditures, tenant improvements and leasing costs (all of which are added to the basis of the properties) related to our life science properties (excluding capital expenditures and tenant improvements that are recoverable from tenants, revenue-enhancing or related to properties that have undergone redevelopment) for the years ended December 31, 2004, 2003, 2002, 2001 and 2000, attributable to leases that commenced at our properties after our acquisition.

  1. Major capital expenditures consist of roof replacements and HVAC systems that are typically identified and considered at the time a property is acquired. Major capital expenditures also include one-time costs related to the implementation of our national branding and signage program. Major capital expenditures for 2004 include a one-time HVAC system upgrade at one property totaling $1,551,000 ($0.25 per square foot in portfolio). Major capital expenditures for 2003 include $1,072,000 ($0.19 per square foot in portfolio) in one-time costs related to the implementation of our national branding and signage program. Recurring capital expenditures for 2002 include $552,000 ($0.10 per square foot in portfolio) related to a fully leased property in San Diego, California that underwent substantial renovation in 2002. Excludes space that has undergone redevelopment before retenanting.

Capital expenditures fluctuate in any given period due to the nature, extent and timing of improvements required and the extent to which they are recoverable from our tenants. Approximately 91% of our leases provide for the recapture of certain capital expenditures (such as HVAC systems maintenance and/or replacement, roof replacement and parking lot resurfacing). In addition, we maintain an active preventative maintenance program at each of our properties to minimize capital expenditures required.

Tenant improvements and leasing costs also fluctuate in any given year depending upon factors such as the timing and extent of vacancies, property age, location and characteristics, the type of lease (renewal tenant or retenanted space), the involvement of external leasing agents and overall competitive market conditions.

Inflation

As of December 31, 2004 and 2003, approximately 83% and 88%, respectively, of our leases (on a 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. The decrease in tripe net leases from 2003 to 2004 is primarily due to gross leases added to the portfolio from properties acquired in 2004. Gross leases are generally converted to triple net leases upon renewal or rollover. In addition, as of December 31, 2004, approximately 7% of our leases (on a square footage basis) required the tenants to pay a majority of operating expenses. Approximately 89% of our leases (on a square footage basis) contained effective annual rent escalations that are either fixed (generally ranging from 3% to 3.5%) or indexed based on the consumer price index or another index. Accordingly, we do not believe that our earnings or cash flow from real estate operations are subject to any significant risk from inflation. An increase in inflation, however, could result in an increase in the cost of our variable rate borrowings, including our unsecured line of credit and unsecured term loan.

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 miscorrelation between real estate values and historical cost accounting for real estate assets, the Board of Governors of the National Association of Real Estate Investment Trusts ("NAREIT") established the measurement tool of Funds From Operations ("FFO"). Since its introduction, FFO has become a widely used non-GAAP financial measure by 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. In 2003, NAREIT issued guidance which modifies the calculation of FFO for both past and future periods. In accordance with NAREIT's revised guidance, we now include losses from early extinguishment of debt and real estate impairment charges in our calculation of FFO. As such, the reported amounts of FFO for the year ended December 31, 2002 have been modified from those previously reported. 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. While FFO is a relevant and widely used measure of operating performance for REITs, it 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. (See "Liquidity and Capital Resources - Cash Flows" above for information regarding these measures of cash flow.) We believe that net income is the most directly comparable GAAP financial measure to FFO.

The following table presents a reconciliation of net income to funds from operations for the years ended December 31, (in thousands):

  2. During the second quarter of 2004, we elected to redeem the 9.50% Series A cumulative redeemable preferred stock. Accordingly, in compliance with Emerging Issues Task Force Topic D-42, we recorded a charge of $1,876,000, or $0.10 per common share (diluted) in the second quarter of 2004 for costs related to the redemption of the Series A preferred stock.
  3. Gain/loss on sales of property relates to the disposition of a property in the Suburban Washington D.C. market during the first quarter of 2004, the disposition of a property in the Suburban Washington D.C. market during the fourth quarter of 2003, the disposition of a property in the Eastern Massachusetts market during the third quarter of 2003, and the disposition of a property in the San Francisco Bay market during the first quarter of 2003. Gain/loss on sales of property is included in the income statement in income from discontinued operations, net.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

Market risk is the exposure to loss resulting from changes in interest rates, foreign currency exchange rates, commodity prices and equity prices. The primary market risk to which we believe we are exposed is interest rate risk, which may result from many factors, including governmental monetary and tax policies, domestic and international economic and political considerations and other factors that are beyond our control.

In order to modify and manage the interest rate characteristics of our outstanding debt and to limit the effects of interest rate risks on our operations, we may utilize a variety of financial instruments, including interest rate swaps, caps, floors and other interest rate exchange contracts. The use of these types of instruments to hedge a portion of our exposure to changes in interest rates carries additional risks, such as counter-party credit risk and the legal enforceability of hedging contracts.

Our future earnings, cash flows and fair values relating to financial instruments are primarily dependent upon prevalent market rates of interest, such as LIBOR. However, our interest rate swap agreements are intended to reduce the effects of interest rate changes. Based on interest rates at, and our swap agreements in effect on, December 31, 2004 and 2003, we estimate that a 1% increase in interest rates on our unsecured line of credit and unsecured term loan, after considering the effect of our interest rate swap agreements, would decrease annual future earnings and cash flows by approximately $2.0 million and $1.4 million, respectively. We further estimate that a 1% decrease in interest rates on our unsecured line of credit and unsecured term loan, after considering the effect of our interest rate swap agreements in effect on December 31, 2004 and 2003, would increase annual future earnings and cash flows by approximately $2.0 million and $1.4 million, respectively. A 1% increase in interest rates on our secured debt and interest rate swap agreements would decrease their aggregate fair value by approximately $27.2 million and $15.3 million at December 31, 2004 and 2003, respectively. A 1% decrease in interest rates on our secured debt and interest rate swap agreements would increase their aggregate fair value by approximately $28.4 million and $16.4 million at December 31, 2004 and 2003, respectively.

These amounts are determined by considering the impact of the hypothetical interest rates on our borrowing cost and our interest rate swap agreements in effect on December 31, 2004 and 2003 . These analyses do not consider the effects of the reduced level of overall economic activity that could exist in such an environment. Further, in the event of a change of such magnitude, we would consider taking actions to further mitigate our exposure to the change. However, due to the uncertainty of the specific actions that would be taken and their possible effects, the sensitivity analysis assumes no changes in our capital structure.

We have exposure to equity price market risk because of our equity investments in certain publicly-traded companies and privately held entities. We classify investments in publicly-traded companies as available-for-sale and, consequently, record them on our balance sheet at fair value with unrealized gains or losses reported as a component of comprehensive income or loss. Investments in privately held entities are generally accounted for under the cost method because we do not influence any of the operating or financial policies of the entities in which we invest. For all investments, we recognize other than temporary declines in value against earnings in the same period the decline in value was deemed to have occurred. In 2002, we recorded non-cash impairment charges of $2,545,000 to write- down certain investments for which we deemed the decline in fair value to be other than temporary. There is no assurance that future declines in values will not have a material adverse impact on our future results of operations. By way of example, a 10% decrease in the fair value of our equity investments as of December 31, 2004 and 2003 would decrease their fair value by approximately $6.7 million and $4.7 million, respectively.

Management's Annual Report on Internal Control Over Financial Reporting

The management of Alexandria Real Estate Equities, Inc. and subsidiaries (the "Company") is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external reporting purposes in accordance with U.S. generally accepted accounting principles. The Company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of assets; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with U.S. generally accepted accounting principles, and that receipts and expenditures are being made only in accordance with the authorizations of the Company's management and directors; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of assets that could have a material effect on the financial statements. Management has assessed the effectiveness of the Company's internal control over financial reporting as of December 31, 2004. In making its assessment, management has utilized the criteria set forth by the Committee of Sponsoring Organizations (COSO) of the Treadway Commission in "Internal Control - Integrated Framework". Management concluded that based on its assessment, the Company's internal control over financial reporting was effective as of December 31, 2004. Management's assessment of the effectiveness of the Company's internal control over financial reporting as of December 31, 2004 has been audited by Ernst & Young LLP, an independent registered public accounting firm, as stated in their report on the next page.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders of
Alexandria Real Estate Equities, Inc.

We have audited management's assessment, included in the accompanying Management's Report on Internal Control Over Financial Reporting, that Alexandria Real Estate Equities, Inc. and subsidiaries (the "Company") maintained effective internal control over financial reporting as of December 31, 2004, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (the "COSO criteria"). The Company's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting. Our responsibility is to express an opinion on management's assessment and an opinion on the effectiveness of the Company's internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, evaluating management's assessment, testing and evaluating the design and operating effectiveness of internal control, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, management's assessment that the Company maintained effective internal control over financial reporting as of December 31, 2004 is fairly stated, in all material respects, based on the COSO criteria. Also, in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2004, based on the COSO criteria.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the accompanying consolidated balance sheets of the Company as of December 31, 2004 and 2003, and the related consolidated statements of income, stockholders' equity, and cash flows for each of the three years in the period ended December 31, 2004, and our report dated March 4, 2005 expressed an unqualified opinion thereon.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders of
Alexandria Real Estate Equities, Inc.

We have audited the accompanying consolidated balance sheets of Alexandria Real Estate Equities, Inc. and subsidiaries (the "Company") as of December 31, 2004 and 2003, and the related consolidated statements of income, stockholders' equity, and cash flows for each of the three years in the period ended December 31, 2004. Our audits also included the financial statement schedule listed in the index at item 15(a). These financial statements and schedule are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements and schedule based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of Alexandria Real Estate Equities, Inc. and subsidiaries at December 31, 2004 and 2003, and the consolidated results of their operations and their cash flows for each of the three years in the period ended December 31, 2004, in conformity with U.S. generally accepted accounting principles. Also, in our opinion, the related financial statement schedule, when considered in relation to the basic financial statements taken as a whole, presents fairly in all material respects the information set forth therein.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the effectiveness of the Company's internal control over financial reporting as of December 31, 2004, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated March 4, 2005, expressed an unqualified opinion thereon.

2. Basis of Presentation and Summary of Significant Accounting Policies

Basis of Presentation

The accompanying consolidated financial statements include the accounts of Alexandria Real Estate Equities, Inc. and its subsidiaries. All significant intercompany balances and transactions have been eliminated.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Reclassifications

Certain prior year amounts have been reclassified to conform to the current year presentation.

Cash Equivalents

We consider all highly liquid investments with original maturities of three months or less when purchased to be cash equivalents.

Accumulated Other Comprehensive Income (Loss)

Accumulated other comprehensive income (loss) consists of the following (in thousands):

                                        December 31,

Investments

We hold equity investments in certain publicly-traded companies and privately held entities primarily involved in the life science industry. All of our investments in publicly-traded companies are considered "available for sale" in accordance with Statement of Financial Accounting Standards No. 115, "Accounting for Certain Investments in Debt and Equity Securities" ("SFAS 115"), and are recorded at fair value. Fair value has been determined as the closing trading price at the balance sheet date, with unrealized gains and losses shown as a separate component of stockholders' equity. The classification of investments under SFAS 115 is determined at the time each investment is made, and such determination is reevaluated at each balance sheet date. The cost of investments sold is determined by the specific identification method, with realized gains and losses included in other income in the accompanying consolidated statements of income.

Investments in privately held entities are generally accounted for under the cost method because we do not influence any operating or financial policies of the entities in which we invest. Certain investments are accounted for under the equity method in accordance with Accounting Principles Board Opinion No. 18, "The Equity Method of Accounting for Investments in Common Stock" ("APB 18") and Emerging Issues Task Force Topic D-46, "Accounting for Limited Partnership Investments" ("EITF Topic D-46"). Under the equity method we record our investment initially at cost and adjust the carrying amount of the investment to recognize our share of the earnings or losses of the investee subsequent to the date of our investment.

For all of our investments, if a decline in the fair value of an investment below its carrying value is determined to be other than temporary, such investment is written-down to its estimated fair value with a non-cash charge to current earnings. The factors that we consider in making these assessments include, but are not limited to, market prices, market conditions, prospects for favorable or unfavorable clinical trial results, new product initiatives and new collaborative agreements.

Rental Properties and Properties Under Development

In accordance with Statement of Financial Accounting Standards No. 141, "Business Combinations", we perform the following procedures when making an allocation of the purchase price of real estate: (1) estimate the value of the real estate as of the acquisition date on an "as if vacant" basis; (2) allocate the "as if vacant" value among land, land improvements, buildings, building improvements, tenant improvements and equipment; (3) calculate the value of the intangibles as the difference between the "as if vacant" value and the purchase price; and (4) allocate the intangible value to above, below and at market leases, origination costs associated with in-place leases, tenant relationships and other intangible assets.

The values allocated to land improvements, buildings, building improvements, tenant improvements and equipment are depreciated on a straight-line basis using an estimated life of 20 years for land improvements, 40 years for buildings and building improvements, the respective lease term for tenant improvements and the estimated useful life for equipment. The values of above and below market leases are amortized over the life of the related lease and recorded as either an increase (for below market leases) or a decrease (for above market leases) to rental income. The values of at-market leases and origination costs are classified as leasing costs, included in other assets in the accompanying consolidated balance sheets and amortized over the remaining life of the lease.

Rental properties and properties under development are individually evaluated for impairment when conditions exist which may indicate that it is probable that the sum of expected future undiscounted cash flows is less than the carrying amount of the property. Upon determination that impairment has occurred, a write-down is recorded to reduce the carrying amount of the property to its estimated fair value.

In accordance with Statement of Financial Accounting Standards No. 34, "Capitalization of Interest Cost" ("SFAS 34") and Statement of Financial Accounting Standards No. 67, "Accounting for Costs and Initial Rental Operations of Real Estate Projects" ("SFAS 67"), we capitalize direct construction and development costs, including predevelopment costs, interest, property taxes, insurance and other costs directly related and essential to the acquisition, development or construction of a project. Pursuant to SFAS 34 and SFAS 67, capitalization of construction and development costs is required while activities are ongoing to prepare an asset for its intended use. Costs incurred after a project is substantially complete and ready for its intended use are expensed as incurred. Costs previously capitalized related to abandoned acquisition or development opportunities are written-off. Should development activity cease, a portion of interest, property taxes, insurance and certain costs would no longer be eligible for capitalization, and would be expensed as incurred. Expenditures for repairs and maintenance are expensed as incurred.

In accordance with Statement of Financial Accounting Standards No. 144, "Accounting for the Impairment or Disposal of Long-Lived Assets" ("SFAS 144"), we classify a property as "held for sale" when all of the following criteria for a plan of sale have been met: (1) management, having the authority to approve the action, commits to a plan to sell the property, (2) the property is available for immediate sale in its present condition, subject only to the terms that are usual and customary, (3) an active program to locate a buyer, and other actions required to complete the plan to sell, have been initiated, (4) the sale of the property is probable and is expected to be completed within one year, (5) the property is being actively marketed for sale at a price that is reasonable in relation to its current fair value, and (6) actions necessary to complete the plan of sale indicate that it is unlikely that significant changes to the plan will be made or that the plan will be withdrawn. When the property is classified as "held for sale", its operations are classified as discontinued operations in our consolidated statements of income. When a property is designated as "held for sale", amounts for all prior periods presented are reclassified from continuing operations to discontinued operations. A loss is recognized for any initial adjustment of the asset's carrying amount to fair value less costs to sell in the period the asset qualifies as "held for sale". Depreciation of assets is discontinued commencing on the date they are designated as "held for sale".

As of December 31, 2004, we had no properties designated as "held for sale" in accordance with SFAS 144. As of December 31, 2003, we had one property designated as "held for sale". This property was sold during the first quarter of 2004. During the year ended December 31, 2003, we sold three properties, two of which were designated as "held for sale" as of December 31, 2002. See Note 13, Discontinued Operations.

                                           ===========  =============

Leasing Costs

Costs directly related and essential to our leasing activities are amortized on a straight-line basis over the term of the related lease. Costs that were previously capitalized and which related to unsuccessful leasing opportunities are written-off. Leasing costs, net of related amortization, totaled $29,747,000 and $18,665,000 as of December 31, 2004 and 2003, respectively, and are included in other assets in the accompanying consolidated balance sheets.

Loan Fees and Costs

Fees and costs incurred in obtaining long-term financing are amortized over the terms of the related loans and included in interest expense in the accompanying consolidated statements of income. Loan fees and costs, net of related amortization, totaled $14,075,000 and $11,556,000 as of December 31, 2004 and 2003, respectively, and are included in other assets in the accompanying consolidated balance sheets.

Rental Income

Rental income from leases with scheduled rent increases, free rent and other rent adjustments are recognized on a straight-line basis over the respective lease terms. We include amounts currently recognized as income, and expected to be received in later years, in deferred rent in the accompanying consolidated balance sheets. Amounts received currently, but recognized as income in future years, are included as unearned rent in accounts payable, accrued expenses and tenant security deposits in the accompanying consolidated balance sheets. Tenant recoveries related to reimbursement of real estate taxes, insurance, repairs and maintenance, and other operating expenses are recognized as revenue in the period the applicable expenses are incurred.

We maintain an allowance for estimated losses that may result from the inability of our tenants to make required payments. If a tenant fails to make contractual payments beyond any allowance, we may recognize additional bad debt expense in future periods equal to the amount of unpaid rent and deferred rent. As of December 31, 2004 and 2003, we had no allowance for doubtful accounts.

Interest Income

Interest income was $181,000, $108,000 and $298,000 in 2004, 2003 and 2002, respectively, and is included in other income in the accompanying consolidated statements of income.

Fair Value of Financial Instruments

The carrying amounts of cash and cash equivalents, tenant receivables, unsecured line of credit and unsecured term loan, and accounts payable, accrued expenses and tenant security deposits approximate fair value.

The fair value of our secured notes payable was estimated using discounted cash flows analyses based on borrowing rates we believe we could obtain with similar terms and maturities. As of December 31, 2004 and 2003, the fair value of our secured notes payable was approximately $652,100,000 and $338,620,000, respectively.

Emerging Issues Task Force Topic D-42, "The Effect on the Calculation of Earnings Per Share for the Redemption or Induced Conversion of Preferred Stock" ("EITF Topic D-42") provides, among other things, that any excess of (1) the fair value of the consideration transferred to the holders of preferred stock redeemed over (2) the carrying amount of the preferred stock, should be subtracted from net earnings to determine net income available to common stockholders in the calculation of earnings per share. The cost to issue our preferred stock was recorded as a reduction to additional paid-in capital in the years that the preferred stock was issued. Upon any redemption of our preferred stock, the respective offering costs, representing the excess of the fair value of the consideration transferred to the holders over the carrying amount of the preferred stock, will be recognized as a dividend to preferred stockholders. During 2004, we recorded a charge of approximately $1,876,000 to net income available to common stockholders for costs related to the redemption of our 9.5% Series A cumulative redeemable preferred stock. Dividends on preferred stock are deducted from net income to arrive at net income allocable to common stockholders.

Stock-Based Compensation Expense

For 2002 and all prior years, we have elected to follow Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to Employees" ("APB 25") and related Interpretations in accounting for our employee and non- employee director stock options, stock grants and stock appreciation rights. Effective January 1, 2003, the Company adopted the fair value recognition provisions of Statement of Financial Accounting Standard No. 123, "Accounting for Stock-Based Compensation" ("SFAS 123"), prospectively to all employee awards granted, modified or settled after January 1, 2003. We did not grant any stock options in 2004 or 2003. Under APB 25, because the exercise price of the options we granted equals the market price of the underlying stock on the date of grant, no compensation expense has been recognized. Although we have elected to follow APB 25 for previously granted options, pro forma information regarding net income and net income per share is required by SFAS 123. This information has been determined as if we had accounted for our stock options under the fair value method under SFAS 123.

For purposes of the following pro forma disclosures, the estimated fair value of the options is amortized to expense over the options' vesting periods (in thousands, except per share information):

Operating Segments

We view our operations as principally one segment and the financial information disclosed herein represents all of the financial information related to our principal operating segment.

Income Taxes

As a REIT, we are not subject to federal income taxation as long as we meet a number of organizational and operational requirements and make distributions greater than or equal to 100% of our taxable income to our stockholders. Since we believe we have met these requirements and our distributions exceeded taxable income, no federal income tax provisions have been reflected in the accompanying consolidated financial statements for the years ended December 31, 2004, 2003 and 2002. If we fail to qualify as a REIT in any taxable year, we will be subject to federal income tax (including any applicable alternative minimum tax) on our taxable income at regular corporate tax rates.

During 2004, 2003 and 2002, we declared dividends on our common stock of $2.52, $2.20 and $2.00 per share, respectively. During 2004, 2003 and 2002, we declared dividends on our Series A cumulative redeemable preferred stock of $1.72847, $2.375 and $2.375 per share, respectively. During 2004, 2003 and 2002, we declared dividends on our Series B cumulative redeemable preferred stock of $2.275, $2.275 and $1.662 per share, respectively. During 2004, we declared dividends on our Series C cumulative redeemable preferred stock of $0.61649. See Note 9 - Preferred Stock and Excess Stock.

Impact of Recently Issued Accounting Standards

In March 2004, the Emerging Issues Task Force ("EITF") of the Financial Accounting Standards Board ("FASB") reached a consensus on Issue No. 03-1, "The Meaning of Other-Than-Temporary Impairment and Its Application to Certain Investments" ("EITF 03-1"). EITF 03-1 provides guidance on other-than-temporary impairment of marketable debt and equity securities accounted for under Statement of Financial Accounting Standards No. 115, "Accounting for Certain Investments in Debt and Equity Securities" ("SFAS 115") and Statement of Financial Accounting Standards No. 124, "Accounting for Certain Investments Held by Not-for-Profit Organizations" (SFAS 124"), and non-marketable equity securities accounted for under the cost method. EITF 03-1 provides a three-step model to determine (1) when an investment is considered impaired; (2) whether the impairment is other-than-temporary; and (3) the measurement of the impairment loss. The guidance also requires certain disclosures about unrealized losses that have not been recognized as other-than-temporary impairments. In addition, EITF 03-1 provides that a company does not have to estimate the fair value of an investment accounted for under the cost method if there are no identified events or changes in circumstances that may have a significant adverse effect on the fair value of the investment. In September 2004, the FASB issued FASB Staff Position ("FSP") 03-1-1, "Effective Date of Paragraphs 10-20 of EITF 03-1, The Meaning of Other-Than-Temporary Impairment and Its Application to Certain Investments", which delays the effective date of the recognition and measurement provisions of EITF 03-1 until certain implementation issues are addressed and a final FSP providing implementation guidance is issued. The Company adopted the disclosure guidance of EITF 03-1 in December 2004. We do not expect the adoption of the recognition and measurement provisions of EITF 03-1 to have a material impact on our financial statements.

In December 2004, the FASB issued Statement of Financial Accounting Standards No. 123 (revised 2004), "Share-Based Payment" ("SFAS 123R"). SFAS 123R requires measurement of all employee stock-based compensation awards using a fair value method and the recording of such expense in the financial statements. This eliminates the accounting for such awards using the intrinsic method pursuant to Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to Employees" ("APB 25"). SFAS 123R is effective beginning in our third quarter of 2005. Upon adoption of SFAS 123R, we intend to use the modified-prospective transition method whereby compensation expense will be recognized relating to the remaining unvested portion of outstanding stock options at the time of adoption, and the expense will be recognized over the remaining service period. We do not expect the adoption of SFAS 123R to have a material impact on our financial statements.

Impact of Recently Issued Accounting Standards (continued)

In December 2004, the FASB issued Statement of Financial Accounting Standards No. 153, "Exchanges of Nonmonetary Assets ("SFAS 153"), which amends Accounting Principles Board Opinion No. 29, "Accounting for Nonmonetary Transactions" ("APB 29"). SFAS 153 addresses the measurement of exchanges of nonmonetary assets and redefines the scope of transactions that should be measured based on the fair value of the assets exchanged. SFAS 153 is effective for nonmonetary asset exchanges beginning in our third quarter of 2005. We do not expect the adoption of SFAS 153 to have a material impact on our financial statements.

As of December 31, 2004 and 2003, certain of our rental properties were encumbered by deeds of trust and assignments of rents and leases associated with the properties. See Note 6, Secured Notes Payable. The net book values of encumbered properties as of December 31, 2004 and 2003 were $776,342,000 and $369,731,000, respectively.

We lease space under noncancelable leases with remaining terms of one to 19 years.

As of December 31, 2004 and 2003, approximately 83% and 88%, respectively, of our leases (on a square footage basis) required that the lessee pay substantially all taxes, maintenance, insurance and certain other operating expenses applicable to the leased properties. The decrease from 2003 to 2004 is primarily due to gross leases added to the portfolio from properties acquired in 2004. Gross leases are generally converted to triple net leases upon renewal or rollover.

Included in rental properties, net as of December 31, 2004 and 2003 were 17 and 10 properties, respectively, in our redevelopment program. The allocated net book values of the portion of these properties undergoing redevelopment as of December 31, 2004 and 2003 were approximately $150,627,000 and $65,559,000, respectively. Depreciation ceases on the portion of a property undergoing redevelopment during the period of redevelopment.

In accordance with SFAS 34, we capitalize interest to properties under development or redevelopment during the period an asset is undergoing activities to prepare it for its intended use. Capitalization of interest ceases after a project is substantially complete and ready for its intended use. In addition, should development activity cease, interest would be expensed as incurred. Total interest capitalized for the years ended December 31, 2004, 2003 and 2002 were $17,902,000, $13,941,000 and $13,519,000, respectively. Total interest incurred for the years ended December 31, 2004, 2003 and 2002 were $46,733,000, $41,571,000 and $40,294,000, respectively.

4. Investments

We hold equity investments in certain publicly-traded companies and privately held entities primarily involved in the life science industry. All of our investments in publicly-traded companies are considered "available for sale" in accordance with SFAS 115, and are recorded at fair value. Investments in privately held entities are generally accounted for under the cost method because we do not influence any operating or financial policies of the entities in which we invest. Certain investments are accounted for under the equity method in accordance with APB 18 and EITF Topic D-46. For all of our investments, if a decline in the fair value of an investment below its carrying value is determined to be other than temporary, such investment is written-down to its estimated fair value with a non-cash charge to current earnings. The factors that we consider in making these assessments include, but are not limited to, market prices, market conditions, prospects for favorable or unfavorable clinical trial results, new product initiatives and new collaborative agreements. For additional discussion of our accounting policies with respect to investments, see Note 2, Basis of Presentation and Summary of Significant Accounting Policies.

The following table summarizes our available-for-sale securities (in thousands):

Investments in available-for-sale securities with gross unrealized losses as of December 31, 2004 and 2003 have been in a continuous unrealized loss position for less than twelve months. We believe that these unrealized losses are temporary and accordingly we have not recognized other-than-temporary impairment related to available-for-sale securities as of December 31, 2004 and 2003.

Our investments in privately held entities as of December 31, 2004 and 2003 totaled $48,295,000 and $45,045,000, respectively. Of these totals, $47,433,000 and $42,331,000 are accounted for under the cost method. The remainder ($862,000 and $2,714,000 for 2004 and 2003, respectively) are accounted for under the equity method in accordance with APB 18 and EITF Topic D-46. As of December 31, 2004 and 2003, there were no unrealized losses in our investments in privately held entities.

Net investment income of $2,436,000 and $536,000 was recognized in 2004 and 2003, respectively, and is included in other income in the accompanying consolidated statements of income. Net investment income in 2004 consisted of equity in income of $208,000 related to investments in privately held entities accounted for under the equity method, gross realized gains of $2,508,000, and gross realized losses of $280,000. Net investment income in 2003 consisted of equity in income of $306,000 related to investments in privately held entities accounted for under the equity method, gross realized gains of $532,000, and gross realized losses of $302,000. During 2002 we recognized an aggregate non-cash impairment charge of $2,545,000 for other-than-temporary declines in the fair value of our investments in private companies.

5. Unsecured Line of Credit and Unsecured Term Loan

In December 2004, we amended our unsecured line of credit to increase our borrowing capacity from $440 million to $500 million. Borrowings under our unsecured line of credit, as amended, bear interest at a floating rate based on our election of either a LIBOR-based rate or the higher of the bank's reference rate and the Federal Funds rate, plus 0.5%. For each LIBOR-based advance, we must elect a LIBOR period of one, two, three or six months. The unsecured line of credit expires December 2007 and may be extended at our sole option for an additional one-year period. As of December 31, 2004, we had borrowings of $298.0 million outstanding on the unsecured line of credit with a weighted average interest rate of 3.72%.

In December 2004, we amended our unsecured term loan to increase the loan from $150 million to $250 million. The unsecured term loan bears interest at a floating rate based on our election of either a LIBOR-based rate or the higher of the bank's reference rate and the Federal Funds rate, plus 0.5%. For each LIBOR-based advance, we must elect to fix for a period of one, two three or six months. The unsecured term loan expires in December 2009. As of December 31, 2004, we had borrowings of $250.0 million outstanding on the unsecured term loan with a weighted average interest rate of 3.72%.

Our unsecured line of credit and unsecured term loan contain financial covenants, including, among other things, maintenance of minimum net worth, a leverage ratio and a fixed charge coverage ratio. In addition, the terms of the unsecured line of credit and unsecured term loan restrict, among other things, certain investments, indebtedness, distributions and mergers.

Aggregate borrowings under the unsecured line of credit and unsecured term loan may be limited to an amount based on the net operating income derived from a pool of unencumbered properties. Accordingly, as we acquire or complete the development or redevelopment of additional unencumbered properties, aggregate borrowings available under the unsecured line of credit and unsecured term loan will increase up to a maximum combined amount of $750 million. Under these provisions as of December 31, 2004, aggregate borrowings under our unsecured line of credit and unsecured term loan were limited to $666 million. Under the amended and restated unsecured line of credit and unsecured term loan, we have an option to increase our maximum available commitment by an additional $100 million.

We utilize interest rate swap agreements to hedge a portion of our exposure to variable interest rates associated with our unsecured line of credit and unsecured term loan. These agreements involve an exchange of fixed and floating interest payments without the exchange of the underlying principal amount (the "notional amount"). Interest received under all of our swap agreements is based on the one-month LIBOR rate. The net difference between the interest paid and the interest received is reflected as an adjustment to interest expense.

The following table summarizes our interest rate swap agreements as of December 31, 2004 (dollars in thousands):

Statement of Financial Accounting Standards No. 133 ("SFAS 133"), "Accounting for Derivative Instruments and Hedging Activities," as amended by Statement of Financial Accounting Standards No. 138, "Accounting for Certain Derivative Instruments and Certain Hedging Activities" establishes accounting and reporting standards for derivative financial instruments such as our interest rate swap agreements. Specifically, SFAS 133 requires us to reflect our interest rate swap agreements on the balance sheet at their estimated fair values. We use a variety of methods and assumptions based on market conditions and risks existing at each balance sheet date to determine the fair values of our interest rate swap agreements. These methods of assessing fair value result in a general approximation of value, and such value may never be realized.

5. Unsecured Line of Credit and Unsecured Term Loan (continued)

All of our interest rate swap agreements meet the criteria to be deemed "highly effective" under SFAS 133 in reducing our exposure to variable interest rates. Accordingly, we have categorized these instruments as cash flow hedges. While we intend to continue to meet the conditions for such hedge accounting, if hedges did not qualify as "highly effective", the changes in the fair value of the derivatives used as hedges would be reflected in earnings.

We do not believe we are exposed to more than a nominal amount of credit risk in our interest rate swap agreements as our counterparties are established, well-capitalized financial institutions.

As of December 31, 2004 and 2003, our interest rate swap agreements have been classified in accounts payable, accrued expenses and tenant security deposits in the accompanying consolidated balance sheets at their fair values of approximately $2.1 million and $6.3 million, respectively. The offsetting adjustments of $2.1 million and $6.3 million, respectively, were reflected as deferred losses in accumulated other comprehensive income (loss) in the stockholders' equity section of the accompanying consolidated balance sheets. Balances in accumulated other comprehensive income (loss) are recognized in earnings as swap payments are made. During the next twelve months, we expect to reclassify $0.9 million from accumulated other comprehensive income (loss) to interest expense.

Our secured notes payable generally require monthly payments of principal and interest. The total net book values of properties securing debt were $776,342,000 and $369,731,000 at December 31, 2004 and 2003, respectively.

8. Non-Cash Transactions

In connection with the acquisitions of ten properties, in ten separate transactions, located in the Eastern Massachusetts, Southeast, Suburban Washington D.C. and San Diego markets in 2004, and the acquisition of a property located in the Eastern Massachusetts market in 2003, we assumed secured notes payable.

In connection with the sale of a property in the Eastern Massachusetts market in August 2003, the buyer assumed a secured note payable totaling $17.3 million.

In 2004, 2003 and 2002, we incurred $3,157,000, $3,354,000 and $3,993,000, respectively, in non-cash stock compensation expense.

9. Preferred Stock and Excess Stock

Series A Cumulative Redeemable Preferred Stock

In July 2004, we redeemed all 1,543,500 outstanding shares of our 9.50% Series A cumulative redeemable preferred stock ("Series A preferred stock") at a redemption price of $25.00 per share plus $0.5409722 per share representing accumulated and unpaid dividends to the redemption date. In accordance with EITF Topic D-42, we recorded a charge of approximately $1,876,000 to net income available to common stockholders during the second quarter of 2004 for costs related to the redemption of the Series A preferred stock. We redeemed our Series A preferred stock with proceeds from the Series C preferred stock offering.

Series B Cumulative Redeemable Preferred Stock

In January 2002, we completed a public offering of 2,300,000 shares of our 9.10% Series B cumulative redeemable preferred stock ("Series B preferred stock") (including the shares issued upon exercise of the underwriters' over- allotment option). The shares were issued at a price of $25.00 per share, resulting in aggregate proceeds of approximately $55.1 million (after deducting underwriters' discounts and other offering costs). The dividends on our Series B preferred stock are cumulative and accrue from the date of original issuance. We pay dividends quarterly in arrears at an annual rate of $2.275 per share. Our Series B preferred stock has no stated maturity, is not subject to any sinking fund or mandatory redemption and is not redeemable prior to January 22, 2007, except in order to preserve our status as a REIT. Investors in our Series B preferred stock generally have no voting rights. On or after January 22, 2007, we may, at our option, redeem our Series B preferred stock, in whole or in part, at any time with proceeds from the sale of equity securities at a redemption price of $25.00 per share, plus accrued and unpaid dividends.

Series C Cumulative Redeemable Preferred Stock

In June 2004, we completed a public offering of 5,185,500 shares of our 8.375% Series C cumulative redeemable preferred stock ("Series C preferred stock") (including the shares issued upon exercise of the underwriters' over- allotment option). The shares were issued at a price of $25.00 per share, resulting in aggregate proceeds of approximately $124.0 million (after deducting underwriters' discounts and other offering costs). The proceeds were used to redeem our Series A preferred stock with the remaining portion used to pay down our unsecured line of credit. The dividends on our Series C preferred stock are cumulative and accrue from the date of original issuance. We pay dividends quarterly in arrears at an annual rate of $2.09375 per share. Our Series C preferred stock has no stated maturity, is not subject to any sinking fund or mandatory redemption and is not redeemable prior to June 29, 2009, except in order to preserve our status as a REIT. Investors in our Series C preferred stock generally have no voting rights. On or after June 29, 2009, we may, at our option, redeem our Series C preferred stock, in whole or in part, at any time for cash at a redemption price of $25.00 per share, plus accrued and unpaid dividends.

Preferred Stock and Excess Stock Authorizations

Our charter authorizes the issuance of up to 100,000,000 shares of preferred stock, of which 7,485,500 shares were issued and outstanding as of December 31, 2004. In addition, 200,000,000 shares of "excess stock" (as defined) are authorized, none of which were issued and outstanding at December 31, 2004.

10. Commitments and Contingencies

Employee Retirement Savings Plan

We have a retirement savings plan pursuant to Section 401(k) of the Internal Revenue Code whereby our employees may contribute a portion of their compensation to their respective retirement accounts, in an amount not to exceed the maximum allowed under the Internal Revenue Code. We have elected to provide discretionary profit sharing contributions (subject to statutory limitations), which amounted to $515,000, $461,000 and $428,000, respectively, for the years ended December 31, 2004, 2003 and 2002. Employees who participate in the plan are immediately vested in their contributions and in the contributions of the company.

Concentration of Credit Risk

We maintain our cash and cash equivalents at insured financial institutions. The combined account balances at each institution periodically exceed FDIC insurance coverage, and, as a result, there is a concentration of credit risk related to amounts in excess of FDIC insurance coverage. We believe that the risk is not significant.

We are dependent on rental income from relatively few tenants in the life science industry. The inability of any single tenant to make its lease payments could adversely affect our operations. As of December 31, 2004, we held leases with a total of 213 tenants and 64 of our 112 properties were each leased to a single tenant. At December 31, 2004, our three largest tenants accounted for approximately 11.6% of our aggregate annualized base rent.

We generally do not require collateral or other security from our tenants, other than security deposits. In addition to security deposits held in cash, we held $32.9 million in irrevocable letters of credit available from certain tenants as security deposits for 73 leases as of December 31, 2004.

Commitments

As of December 31, 2004, we were committed under the terms of construction contracts to complete the construction of properties under development at a remaining aggregate cost of $18.3 million.

As of December 31, 2004, we were also committed to fund approximately $23.2 million for the construction of building infrastructure improvements under the terms of leases and/or construction contracts and approximately $17.2 million for certain investments.

Ground lease obligations as of December 31, 2004 include leases at seven of our properties and one land development parcel. These lease obligations, of approximately $65.3 million, have remaining lease terms of 28 to 51 years, exclusive of extension options.

11. Stock Option Plans and Stock Grants

1997 Stock Plan

In 1997, we adopted a stock option and incentive plan (the "Stock Plan") for the purpose of attracting and retaining the highest quality personnel, providing for additional incentives and promoting the success of the company by providing employees the opportunity to acquire common stock pursuant to (i) options to purchase common stock; and (ii) share awards. As of December 31, 2004, a total of 218,790 shares were reserved for the granting of future options and share awards under the Stock Plan.

Options under our plan have been granted at prices that are equal to the market value of the stock on the date of grant and expire ten years after the date of grant. Employee options vest ratably in three annual installments from the date of grant. Non-employee director options vest immediately on the date of grant. The options outstanding under the Stock Plan expire at various dates through October 2012.

In addition, the Stock Plan permits us to issue share awards to our employees and non-employee directors. A share award is an award of common stock, which (i) may be fully vested upon issuance or (ii) may be subject to the risk of forfeiture under Section 83 of the Internal Revenue Code. Shares issued generally vest over a one to three year period from the date of issuance and the sale of the shares is restricted prior to the date of vesting. During 2004, we awarded 130,143 shares of common stock. The unearned portion of these awards is amortized as stock compensation expense on a straight-line basis over the vesting period.

The fair value of the options issued under the Stock Plan was estimated at the date of grant using a Black-Scholes option pricing model with the following weighted average assumptions for 2004, 2003 and 2002:


                                                   Year Ended December 31,

Income from discontinued operations, net includes the operating results of one property we sold during 2004, three properties we sold during 2003 and four properties that have been designated as "held for sale" at December 31, 2002 under the provisions of SFAS 144. See Note 2, Basis of Presentation and Summary of Significant Accounting Policies.

During the first quarter of 2004, we sold one property located in the Suburban Washington D.C. market that had been designated as "held for sale" as of December 31, 2003. The total sale price for the property was approximately $5.7 million. In connection with the sale, we recorded a gain on sale of property of approximately $1.6 million. During the fourth quarter of 2003, we sold one property located in the Suburban Washington D.C. market that had been designated as "held for sale" during the fourth quarter of 2003. The total sale price for the property was approximately $9.0 million. In connection with the sale, we recorded a loss on sale of property of approximately $36,000. During the third quarter of 2003, we sold one property located in the Eastern Massachusetts market that had been previously designated as "held for sale" as of December 31, 2002. The total sale price for the property was approximately $46.5 million. In connection with this sale, we recorded a gain on sale of property of approximately $8.8 million. Interest expense included in discontinued operations represents interest related to a secured note payable, which was assumed by the buyer in connection with the sale of this property. During the first quarter of 2003, we sold one property located in the San Francisco Bay market which could not be redeveloped pursuant to our original strategic objectives and that had been designated as "held for sale" as of December 31, 2002. The total sale price for the property was approximately $6.8 million. In connection with this sale, we recorded a loss on sale of property of approximately $455,000 in 2003. Gains and losses on sales of these properties are included on the income statement in income from discontinued operations, net. The non-cash impairment charge of $1.2 million in discontinued operations in 2002 relates to the reduction in the net book value as of December 31, 2002 of the property in the San Francisco Bay market which could not be redeveloped and was sold in the first quarter of 2003.
