Normalized FFO was $0.16 per share, or $35.4 million, for the three months ended September 30, 2012, compared to $0.12 per share, or $28.6 million, for the three months ended September 30, 2011. Normalized FAD Normalized Funds Available for Distribution, or Normalized FAD, was $0.13 per share, or $29.1 million, for the three months ended September 30, 2012, an increase of 18.2% from $0.11 per share, or $24.5 million, in 2011. Rental Income Rental income increased 12.8% to $77.0 million for the three months ended September 30, 2012, compared to $68.3 million for the three months ended September 30, 2011. The increase in rental income was driven by $300.2 million of completed acquisitions since September 30, 2011, and same property portfolio growth. NOI Net Operating Income, or NOI, was $52.3 million for the three months ended September 30, 2012, compared to $47.1 million for the three months ended September 30, 2011. Same Property Cash NOI Same property cash NOI increased 2.4% to $43.5 million for the three months ended September 30, 2012, compared to $42.5 million for the three months ended September 30, 2011. General and Administrative Expenses General and administrative expenses were $5.2 million for the three months ended September 30, 2012, compared to $5.5 million for the three months ended September 30, 2011. Management believes the Company’s general and administrative expense reflects HTA’s normalized operations at this time as a publicly traded REIT. Interest Expense and Change in the Fair Value of Derivative Financial Instruments Interest expense and change in the fair value of derivative financial instruments for the three months ended September 30, 2012 was $14.1 million, which included $11.6 million of interest expense related to debt and interest rate swaps and a $2.5 million net loss on the change in the fair value of HTA’s derivative financial instruments. During the quarter, HTA paid off two mortgage notes totaling $25.0 million. During the first nine months of 2012, HTA entered into over $1.0 billion of new credit facilities which has been used to refinance its previous credit facility, pay off $100.3 million of existing mortgage debt, and to fund HTA’s acquisitions and other initiatives, including the tender offer. The net impact from these transactions has been to lower the average borrowing rate and extend maturities. The weighted average borrowing cost, inclusive of HTA’s interest rate swaps and cap, has decreased to 4.02% per annum, a decrease from 5.25% per annum as of December 31, 2011. Additionally, the weighted average remaining term of the debt portfolio increased from 4.1 years to 4.4 years. Acquisitions Since January 1, 2012, HTA has completed four new acquisitions and expanded one of its existing portfolios through the purchase of an additional medical office building for an aggregate purchase price of $268.2 million.

Acquisition-Related Expenses: Prior to 2009, acquisition-related expenses were capitalized and have historically been added back to FFO over time through depreciation; however, beginning in 2009, acquisition-related expenses related to business combinations are expensed. We believe by excluding expensed acquisition-related expenses, Normalized FFO provides useful supplemental information that is comparable for our real estate investments. Adjusted Earnings Before Interest Taxes, Depreciation and Amortization (Adjusted EBITDA): Is presented on an assumed annualized basis. We define Adjusted EBITDA for HTA as net (loss) income attributable to controlling interest computed in accordance with GAAP plus interest, depreciation, amortization, stock based compensation, change in fair value of derivatives, acquisition expenses, debt extinguishment costs, and listing expenses. We consider Adjusted EBITDA an important measure because it provides additional information to allow management, investors, and our current and potential creditors to evaluate and compare our core operating results and our ability to service debt. The following is a reconciliation of our net income (loss) attributable to controlling interest, the most directly comparable GAAP financial measure, to Adjusted EBITDA. Annualized Base Rent: Annualized base rent is calculated by multiplying contractual base rent for September 2012 by 12 (but excluding the impact of abatements, concessions, and straight-line rent). Credit Ratings: Credit ratings of our tenants or their parent companies. Funds from Operations (FFO): HTA defines FFO, a non-GAAP measure, as net income or loss computed in accordance with GAAP, excluding gains or losses from sales of property and impairment write downs of depreciable assets, plus depreciation and amortization, and after adjustments for unconsolidated partnerships and joint ventures. HTA presents FFO because it considers it an important supplemental measure of its operating performance and believes it is frequently used by securities analysts, investors and other interested parties in the evaluation of REITs, many which present FFO when reporting their results. FFO is intended to exclude GAAP historical cost depreciation and amortization of real estate and related assets, which assumes that the value of real estate diminishes ratably over time. Historically, however, real estate values have risen or fallen with market conditions. Because FFO excludes depreciation and amortization unique to real estate, gains and losses from property dispositions and extraordinary items, it provides a performance measure that, when compared year over year, reflects the impact to operations from trends in occupancy rates, rental rates, operating costs, development activities and interest costs, providing perspective not immediately apparent from net income or loss. FFO should not be considered as an alternative to net income or loss (computed in accordance with GAAP) as an indicator of our financial performance or to cash flow from operating activities (computed in accordance with GAAP) as an indicator of our liquidity, nor is it indicative of funds available to fund HTA’s cash needs, including its ability to make distributions. FFO should be reviewed in connection with other GAAP measurements. Gross Leasable Area (GLA): Gross leasable area (in square feet). Gross Real Estate Investments: Based on acquisition price and includes one portfolio of real estate notes receivable. Net Operating Income (NOI): NOI is a non-GAAP financial measure that is defined as net income or loss, computed in accordance with GAAP, generated from HTA’s total portfolio of properties before general and administrative expenses, acquisition-related expenses, depreciation and amortization expense, listing expenses, non-traded REIT expenses, interest expense and net change in the fair value of derivative financial instruments, debt extinguishment costs and other income or expense. HTA believes that NOI provides an accurate measure of the operating performance of its operating assets because NOI excludes certain items that are not associated with management of the properties. Additionally, HTA believes that NOI is a widely accepted measure of comparative operating performance in the real estate community. However, HTA’s use of the term NOI may not be comparable to that of other real estate companies as they may have different methodologies for computing this amount. Reporting Definitions For the Three Months Ended September 30, 2012 Adjusted EBITDA Net (loss) income $(2,931) Add: Depreciation and amortization 29,458 Interest expense, net 14,132 EBITDA $40,659 Acquisition-related expenses 1,341 Debt extinguishment costs - Listing expenses 4,751 Non-cash compensation expense 175 Adjusted EBITDA $46,926 Adjusted EBITDA Annualized $187,704 18

Cash Net Operating Income (NOI): Cash NOI is a non-GAAP financial measure which excludes from NOI straight line rent adjustments, amortization of acquired below and above market leases and other non-cash and normalizing items. HTA believes that Cash NOI provides an accurate measure of the operating performance of its operating assets because it excludes certain items that are not associated with management of the properties. Additionally, HTA believes that Cash NOI is a widely accepted measure of comparative operating performance in the real estate community. However, HTA's use of the term Cash NOI may not be comparable to that of other real estate companies as they may have different methodologies for computing this amount. Normalized Funds Available for Distribution (Normalized FAD): HTA defines normalized FAD, a non-GAAP measure, which excludes from normalized FFO other income or expense, non-cash compensation expense, straight-line rent adjustments, amortization of acquired below and above market leases, deferred revenue - tenant improvement related, amortization of deferred financing costs and recurring capital expenditures, tenant improvements and leasing commissions. HTA believes normalized FAD provides a meaningful supplemental measure of our ability to fund its ongoing distributions. In order to understand and analyze HTA's liquidity, normalized FAD should be compared with cash flow (computed in accordance with GAAP). Normalized FFO should not be considered as an alternative to net income or loss (in accordance with GAAP) as an indication HTA's financial performance or to cash flow from operating activities (in accordance with GAAP) as an indicator of HTA's liquidity. Normalized FAD should be reviewed in connection with other GAAP measurements. Normalized Funds From Operations (Normalized FFO): Changes in the accounting and reporting rules under GAAP have prompted a significant increase in the amount of non-operating items included in FFO, as defined. Therefore, HTA uses normalized funds from operations, or normalized FFO, which excludes from FFO acquisition-related expenses, listing expenses, transitional expenses from a non-traded to a listed entity, net change in fair value of derivative financial instruments, debt extinguishment costs and other normalizing items, to further evaluate how its portfolio might perform after its acquisition stage is complete and the sustainability of its distributions in the future. Other normalizing items are items such as legal settlements, lease termination fees and the write-off of deferred financing costs. However, HTA's use of the term normalized FFO may not be comparable to that of other real estate companies as they may have different methodologies for computing this amount. Normalized FFO should not be considered as an alternative to net income or loss (computed in accordance with GAAP) as an indicator of HTA's financial performance or to cash flow from operating activities (computed in accordance with GAAP) as an indicator of HTA's liquidity, nor is it indicative of funds available to fund HTA’s cash needs, including its ability to make distributions. Normalized FFO should be reviewed in connection with other GAAP measurements. Occupancy: Occupancy represents the percentage of total gross leasable area that is leased, including month-to-month leases and leases that are signed but not yet commenced, as of the date reported. Off-Campus: A building or portfolio that is not located on or adjacent to key hospital based-campuses and is not aligned with recognized healthcare systems. On-Campus / Health System Aligned: On-campus refers to refer to a property that is located on or adjacent to (within ¼ mile) a healthcare system. Aligned refers to a property that is not on the campus of a healthcare system and located greater than ¼ mile from such a campus, but leased 50% or more to a healthcare system. Recurring Capital Expenditures, Tenant Improvements, Leasing Commissions: Represents amounts paid for 1) recurring capital expenditures required to maintain and re-tenant our properties, 2) second generation tenant improvements, and 3) leasing commissions paid to third party leasing agents to secure new tenants. Retention: Tenant Renewal Ratio is defined as the sum of the total leased GLA of tenants that renew an expiring lease over the total GLA of expiring leases. Same Property Cash Net Operating Income: To facilitate the comparison of Cash NOI between periods, HTA calculates comparable amounts for a subset of our owned properties referred to as "same properties." Same property amounts are calculated as the amounts attributable to properties which have been owned and operated by HTA during the entire span of all periods reported. Therefore, any properties acquired after the first day of the earlier comparison period are excluded from same properties. Reporting Definitions (continued) 19
