Hudson Pacific Properties, Inc.

We are a full-service, vertically integrated real estate company focused on owning, operating and acquiring high-quality office properties and state-of-the-art media and entertainment properties in select growth markets primarily in Northern and Southern California and the Pacific Northwest. Our investment strategy focuses on high barrier-to-entry, in-fill locations with favorable, long-term supply demand characteristics in select markets, including Los Angeles, Orange County, San Diego, San Francisco, Silicon Valley and Seattle.

As of December 31, 2014, our portfolio included office properties, comprising an aggregate of approximately 5.5 million square feet, and media and entertainment properties, comprising approximately 0.9 million square feet of sound-stage, office and supporting production facilities. We also own undeveloped density rights for approximately 1.9 million square feet of future development space. Our properties are concentrated in premier submarkets that have high barriers to entry with limited supply of land, high construction costs and rigorous entitlement processes.

We have elected to be taxed as a REIT for federal income tax purposes, commencing with our taxable year ended December 31, 2010. We believe that we have operated in a manner that has allowed us to qualify as a REIT for federal income tax purposes commencing with such taxable year, and we intend to continue operating in such a manner. We conduct substantially all of our business through our operating partnership, of which we serve as the sole general partner.

Recent Developments

Target Portfolio Acquisition

On December 6, 2014, we entered into an asset purchase agreement, or the purchase agreement, with certain affiliates of The Blackstone Group L.P., or Blackstone, which we refer to herein as the seller parties, pursuant to which we agreed to acquire a portfolio of 26 high-quality office assets totaling approximately 8.2 million square feet and two development parcels in the San Francisco Peninsula and Silicon Valley, or the Target Properties, from the seller parties. Pursuant to the terms of the purchase agreement, in consideration for the purchase and sale of the Target Properties, our operating partnership will deliver to the seller parties a cash payment of $1.75 billion and equity consideration consisting of an aggregate amount of up to 63,474,791 shares of our common stock and common units of limited partnership interest in our operating partnership, or common units, subject in each case to adjustments as described therein. The number of shares of our common stock to be issued will be equal to 9.8% of the total issued and outstanding shares of our common stock (excluding any restricted shares of our common stock then issued and outstanding but, for purposes of such calculation, after giving effect to the issuance of the common stock to the seller parties) on the close of business two business days immediately prior to the date of the consummation of the acquisition. The remainder of the equity consideration will consist of common units.

The issuance of the equity consideration will require the affirmative vote of a majority of votes cast at a meeting of our stockholders, which meeting is currently scheduled in March 2015. We refer to the Target Properties collectively herein as the Target Portfolio.

Rationale for Acquisition

We expect the acquisition of the Target Portfolio to have the following benefits.

•

High-Quality Portfolio. We believe the Target Properties, which consist of a critical mass of high-quality office assets in the San Francisco Peninsula and Silicon Valley, present an acquisition opportunity of a size and quality not otherwise available in their respective geographic markets.

•

Opportunity to Leverage Existing Operating Platform. We believe the Target Properties present an opportunity for us to leverage our existing operating platform to create near- and long-term value through our leasing, operating, repositioning and development expertise.

•

Embedded Leasing Potential. We believe a number of the Target Properties currently have above-market vacancy and below-market rental rates, presenting an opportunity to increase our net operating income through the initial lease-up of vacancies and releasing expiring below-market leases at market rental rates. We believe the in-place rental rates at the Target Properties are on average approximately 15% below our estimate of comparable rental rates in their respective markets.

•

Large Unencumbered Asset Base. The Target Properties will not be encumbered by indebtedness, presenting us with the opportunity to place new financing and create a large unencumbered asset base to support a potential investment grade rating in the future.

•

Long-term Relationship with Blackstone. We believe we will benefit from a long-term relationship with Blackstone as a sizable equity holder, including the opportunity to potentially leverage Blackstone’s industry relationships, global capital sources and market intelligence.

•

Increased Scale Advantages. We believe we will benefit from the combination of the Target Properties with our existing property portfolio, including through increased market capitalization and scale, improved access to the capital markets, strong cash flow growth potential, a stronger balance sheet, enhanced investment and redevelopment opportunities, broadened tenant mix, increased geographic and asset-class diversity, improved overhead efficiency ratios and potential cost synergies.

Overview of the Target Portfolio

As of September 30, 2014, the Target Properties were approximately 85.4% leased (giving effect to leases signed but not commenced as of that date). All the properties are located in Northern California. As of September 30, 2014, the weighted average remaining lease term for the properties was 36 months.

Lease Distribution of the Target Portfolio

The following table sets forth information relating to the distribution of leases in the Target Portfolio based on net rentable square feet under lease as of September 30, 2014.

(2)	Annualized base rent is calculated by multiplying (i) base rental payments (defined as cash base rents (before abatements)), including uncommenced leases, as of September 30, 2014, by (ii) 12. Annualized base rent does not reflect tenant reimbursements.

(3)	Annualized base rent per square foot relates to a health club at the Skyport Plaza property.

The acquisition of the Target Portfolio is subject to customary closing requirements and conditions. There can be no assurance that the acquisition will close, or if it does, when the closing will occur. We expect to use the net proceeds from this offering for a portion of the cash consideration for the acquisition; however, the acquisition is not dependent on this offering and we expect to consummate this offering prior to the closing (if any) of the acquisition.

Bridge Facility Commitment Letter

Contemporaneously with the execution of the purchase agreement, we obtained a debt financing commitment for the transactions contemplated by the purchase agreement, the aggregate proceeds of which we will use to pay a portion or all of the cash consideration to consummate the acquisition and to pay related fees and expenses.

Wells Fargo Bank, National Association, Wells Fargo Securities, LLC, Bank of America, N.A., Merrill Lynch, Pierce, Fenner & Smith Incorporated, Goldman Sachs Bank USA, or collectively the bridge facility commitment parties, have committed to provide a 364-day bridge term loan of $1.75 billion, or the bridge loan, to our operating partnership on the terms and conditions set forth in a commitment letter, or the bridge commitment letter, and fee letter, each dated December 6, 2014. Wells Fargo Bank, National Association, Bank of America, N.A., and Goldman Sachs Bank USA have committed to fund the principal amount of the bridge loan as follows: Wells Fargo Bank, National Association, 50%; Goldman Sachs Bank USA, 25%; Bank of America, N.A., 25%.

The obligation of the bridge facility commitment parties to provide financing under the bridge commitment letter are subject to certain conditions, including, without limitation, (i) the negotiation, execution and delivery of definitive loan documentation for the bridge loan consistent with the bridge commitment letter and otherwise reasonably satisfactory to the bridge facility commitment parties, (ii) a condition that there has not been a “Target Property Material Adverse Effect” (as defined in the bridge commitment letter), (iii) the consummation of the acquisition in accordance with the purchase agreement (without giving effect to any amendments to the purchase agreement or any waivers thereof that are materially adverse to the bridge facility commitment parties unless consented to by the bridge facility commitment parties) concurrently with the funding of the bridge loan, (iv) the payment of applicable costs, fees and expenses, and (v) the delivery of certain customary closing documents (including, among other things, opinions from legal counsel). The principal amount of the bridge loan may be reduced in connection with certain equity and debt issuances by us and/our operating partnership, as well as in connection with certain asset sales.

The bridge commitment letter terminates on July 4, 2015.

First Financial Disposition

On December 29, 2014, Hudson First Financial Plaza, LLC, a wholly owned subsidiary of our operating partnership, entered into a purchase and sale agreement with Douglas Emmett Management, LLC, pursuant to which we agreed to sell our First Financial office property located in Encino, California for a purchase price of $89.0 million (before certain credits, proration and closing costs). First Financial is a six-story, 222,423-square-foot, multi-tenant office building with a four-level parking garage, which we acquired upon consummation of our initial public offering in June 2010. The purchase and sale agreement includes customary representations, warranties, covenants and indemnities. The closing of the sale is expected to take place in the first quarter of 2015, upon the completion of certain conditions and obligations, including the assumption of an existing $43.0 million loan. We intend to use the proceeds from the sale in a like-kind exchange pursuant to Section 1031 of the Internal Revenue Code of 1986, as amended, or a Section 1031 Exchange, to defer some or all of the taxable gains for federal and state income tax purposes resulting from the sale, including by applying the proceeds to our purchase of the Target Properties.

1455 Market Street Joint Venture

On January 7, 2015, our operating partnership transferred a 45% interest in Hudson 1455 Market, L.P., the sole common member of Hudson 1455 Market Street LLC, the owner of the 1455 Market Street office property located in San Francisco, California, or the 1455 Market Street Joint Venture, to CPP Investment Board Real Estate Holdings Inc., a wholly owned subsidiary of the Canada Pension Plan Investment Board, for a purchase price of $219.2 million (before certain credits, proration and closing costs). Prior to such transfer, our operating partnership owned 100% of the interests in Hudson 1455 Market, L.P. 1455 Market Street is a 22-story, 1,025,833-square-foot, Class-A office building that fronts an entire block along 11th Street in San Francisco’s Mid-Market neighborhood. We intend to use the proceeds from the 1455 Market Street Joint Venture in a Section 1031 Exchange to defer some or all of the taxable gains for federal and state income tax purposes resulting from the formation of the 1455 Market Street Venture, including by applying the proceeds to our purchase of the Target Properties.

6922 Hollywood Mortgage Loan Payoff

On October 2, 2014, we fully repaid the $39.7 million loan secured by our 6922 Hollywood Boulevard property in Hollywood, California. The loan was scheduled to mature on January 1, 2015.

12655 Jefferson Acquisition

On October 17, 2014, we acquired a 93,952 square-foot office property located in the Playa Vista submarket of Los Angeles, California in an off-market transaction for $38.0 million (before certain credits, closing costs, and prorations). The purchase price was paid from borrowings under our revolving credit facility. Built in 1985, the property includes a garage with 279 parking stalls. The building is currently vacant and conceptual designs and plans have been completed for a creative office conversion. Playa Vista is a leading submarket for creative office tenants, including Facebook, Google/YouTube, Microsoft and Sony.

See “Restrictions on Ownership and Transfer” in the accompanying prospectus.

Risk factors

Investing in our common stock involves a high degree of risk and the purchasers of our common stock may lose all or part of their investment. Before deciding to invest in our common stock, please carefully read the section entitled “Risk Factors,” including the risks incorporated therein from our most recent Annual Report on Form 10-K for the year ended December 31, 2013 and our other periodic reports filed with the Securities and Exchange Commission and incorporated by reference herein.

(1)

Excludes (i) 1,650,000 shares of our common stock issuable upon the exercise of the underwriters’ option to purchase additional shares in full, (ii) shares of common stock issuable upon exchange of outstanding 6.25% Cumulative Redeemable Convertible Series A Preferred Units of partnership interest in our operating partnership, or Series A Preferred Units, with an aggregate liquidation preference of approximately $10.2 million, which became convertible or redeemable on June 29, 2013, (iii) a maximum of 4,757,387 shares of our common stock available for issuance in the future under our equity incentive plan and (iv) shares of our common stock that may be issued in connection with the acquisition of the Target Portfolio (which, if issued, will be equal to 9.8% of the total issued and outstanding shares of our common stock (excluding any restricted shares of our common stock then issued and outstanding but, for purposes of such calculation, after giving effect to the issuance of the common stock to the seller parties) on the close of business two business days immediately prior to the date of the consummation of the acquisition). As of January 12, 2015, up to 14,034,292 fungible units may be granted in the future under our equity incentive plan in any combination of five-year options, ten-year options or restricted stock (inclusive of any equity grants that may be made in the future under our outperformance programs). A maximum of 17,992,682, 14,034,292 or 4,757,387 shares of our common stock are available for issuance in the future under our equity incentive plan if such fungible units are granted as five-year options, ten-year options or restricted stock, respectively.

(2)

Includes 2,382,563 common units held by limited partners of our operating partnership, which units may, subject to certain limitations and adjustments, be redeemed for cash or, at our option, exchanged for shares of common stock on a one-for-one basis. Excludes common units that may be issued in connection with the acquisition of the Target Portfolio (which, if issued, will be in an amount equal to 63,474,791, less the number of shares of our common stock issued in connection with the acquisition of the Target Portfolio, as described above, subject to reduction as described in the purchase agreement).

Investing in our common stock involves risks. You should carefully consider the following risks, the risks described in our Annual Report on Form 10-K for the year ended December 31, 2013, as well as the other information and data set forth in this prospectus supplement, the accompanying prospectus and the documents incorporated by reference herein and therein before making an investment decision with respect to the common stock. The risks associated with our business and properties described or incorporated by reference herein, to the extent that they relate generally to the ownership and operation of real estate, will also apply to the ownership and operation of the Target Properties if the acquisition is consummated. The occurrence of any of the following risks could materially and adversely affect our business, prospects, financial condition, results of operations and our ability to make cash distributions to our stockholders, which could cause you to lose all or a part of your investment in our common stock. Some statements in this prospectus supplement, including statements in the following risk factors, constitute forward-looking statements. See “Forward-Looking Statements.”

The issuance of shares of our common stock in the acquisition or upon exchange of common units received in the acquisition of the Target Properties will have a dilutive effect on our common stock and will reduce the relative percentage interests of our stockholders in our earnings, voting power and market value.

The equity portion of the acquisition consideration for the Target Portfolio consists of up to an aggregate of 63,474,791 shares of our common stock and common units. The number of shares of our common stock to be issued to the seller parties will be equal to approximately 9.8% of the total issued and outstanding shares of our common stock (excluding any restricted shares of our common stock then issued and outstanding but, for purposes of such calculation, after giving effect to the issuance of the common stock to the seller parties) on the close of business two business days immediately prior to the date of the consummation of the acquisition. The remainder of the equity consideration will consist of common units. The issuance of shares of our common stock in the acquisition will have a dilutive effect on our common stock and will reduce the relative percentage interests of our common stockholders in our earnings, voting power and market value.

Additionally, part of the equity portion of the acquisition consideration will be paid in common units, which may have a dilutive effect on our common stock. Holders of common units have the right to require the redemption of part or all of their outstanding common units for cash, or, at our election, shares of our common stock, based upon the fair market value of an equivalent number of shares of our common stock at the time of the redemption, subject to certain restrictions on ownership and transfer of our common stock. If the seller parties exercise their redemption rights and part or all of their outstanding common units are exchanged for shares of our common stock, such exchange will have a dilutive effect on our common stock and reduce the relative percentage interests of our existing common stockholders (including investors in shares of our common stock offered hereby) in our earnings, voting power and market value.

If the acquisition does not occur, we may incur payment obligations to the seller parties.

If the purchase agreement is terminated because our common stockholders do not approve the issuance of the equity portion of the acquisition consideration, we will be obligated to pay the seller parties up to $14 million in expense reimbursement. If the purchase agreement is terminated under certain other circumstances, we will be obligated to pay the seller parties a termination fee of up to $120 million, net of certain expense reimbursements.

Failure to complete the acquisition in a timely manner could negatively affect our ability to achieve the benefits associated with the acquisition and could negatively affect our share price and future business and financial results.

The acquisition is currently expected to close during the first half of 2015, assuming that all of the conditions in the purchase agreement are satisfied or waived. The purchase agreement provides that either we or

the seller parties may terminate the purchase agreement if the closing of the acquisition has not occurred by 11:59 p.m. New York time on July 3, 2015. Certain events outside our control may delay or prevent the consummation of the acquisition. Delays in consummating the acquisition or the failure to consummate the acquisition at all may result in our incurring significant additional costs in connection with such delay or termination of the purchase agreement and/or failing to achieve the anticipated benefits associated with the acquisition. We cannot assure you that the conditions to the completion of the acquisition will be satisfied or waived or that any adverse effect, event, development or change will not occur, and we cannot provide any assurances as to whether or when the acquisition will be completed.

To complete the acquisition, our common stockholders must approve the issuance of the equity consideration. In addition, the purchase agreement contains additional closing conditions, which may not be satisfied or waived. Delays in consummating the acquisition or the failure to consummate the acquisition at all could negatively affect our future business and financial results, and, in that event, the per share trading price of our common stock may decline significantly, particularly to the extent that the current market price reflects a market assumption that the acquisition will be consummated. If the acquisition is not consummated for any reason, our ongoing business could be adversely affected, and we will be subject to several risks, including:

In addition, in the event the acquisition is not consummated, we will have issued additional shares of our common stock in this offering without realizing a corresponding increase in earnings and cash flow from acquiring the Target Properties. We will also have broad authority to use the net proceeds of this offering for other purposes that may not be accretive to our earnings per share and funds from operations per share. As a result, if the acquisition is not consummated, we will not achieve the expected benefits thereof and will be subject to the risks described above, any of which could affect the per share trading price of our common stock and our future business and financial results.

The pendency of the acquisition could adversely affect our business and operations and the Target Properties.

In connection with the pending acquisition, some of our, or the seller parties’, current or prospective tenants, lenders, joint venture partners or vendors may delay or defer decisions, which could negatively impact our, or the seller parties’, revenues, earnings, cash flows and expenses, regardless of whether the acquisition is completed. In addition, under the purchase agreement, both we and the seller parties are subject to certain restrictions on the conduct of our respective businesses prior to completing the acquisition. These restrictions may prevent the parties from pursuing certain strategic transactions, undertaking certain significant capital projects, undertaking certain significant financing transactions and otherwise pursuing other actions that are not in the ordinary course of business, even if such actions would prove beneficial.

We will incur significant non-recurring costs in connection with the acquisition.

We expect to incur a number of non-recurring costs associated with transferring and integrating the Target Properties into our business, including any planned renovation, development or lease-up of such properties. Under the terms of the purchase agreement, we are obligated to pay all expenses incurred in connection with the acquisition at closing (subject to certain exceptions). The majority of non-recurring costs relating to the acquisition are comprised of transaction costs, costs of transferring the Target Properties and costs related to formulating integration plans. We expect that approximately $40.6 million of costs will be incurred to complete the acquisition although additional unanticipated costs may be incurred in the integration of the Target Properties into our business. As of December 31, 2014, we have incurred $12.4 million in non-recurring costs in connection with the acquisition, which does not include any fees for which we will need to reimburse the seller parties or others at the closing of the acquisition.

There can be no assurance that we will be able to obtain financing for the funds necessary to pay the cash portion of the acquisition consideration on acceptable terms, in a timely manner, or at all.

Our obligation under the purchase agreement to consummate the acquisition is not conditioned on us obtaining any financing for the acquisition. In connection with the acquisition, we have obtained commitments for up to $1.75 billion under a 364-day senior unsecured bridge loan facility to finance the cash portion of the acquisition consideration, subject to certain conditions. We are also pursuing a number of financing options and anticipate that the funds needed to complete the acquisition will be derived from a combination of the net proceeds from this offering, our available cash on hand, proceeds from the sale of equity interests in, or assets of, certain wholly or partially owned subsidiaries, the issuance and sale of additional common and/or preferred stock and/or limited partnership interests in the operating partnership and debt financing, which may include, without limitation, some combination of the following: (a) a senior unsecured bridge loan facility, (b) the issuance of senior unsecured notes or other debt securities, (c) borrowings under the operating partnership’s existing corporate credit facility and/or an upsizing thereof, including pursuant to the incremental feature thereof, (d) secured asset level financing and/or (e) other commercial or institutional bank loans.

There can be no assurance that we will satisfy the conditions needed to enter into the committed 364-day senior unsecured bridge loan facility or that we will be able to obtain alternative financing on acceptable terms, in a timely manner or at all. If we utilize the committed 364-day senior unsecured bridge loan facility, we would need to refinance such indebtedness within one year and there can be no assurance that we would be able to do so on acceptable terms, in a timely manner or at all, particularly because we would only utilize our committed 364-day senior unsecured bridge facility if alternative financing on better terms was not available to us. The committed 364-day senior unsecured bridge facility contains provisions that are not favorable to us, including a duration fee that is payable every 90 days after the funding of the bridge and that steps up over time, as well as mandatory prepayment requirements for, among other things, debt and equity issuances and asset sales. If we are unable to obtain the funds necessary to pay the cash portion of the acquisition consideration, we may not be able to complete the acquisition and may be required to pay the seller parties a termination fee of up to $120 million.

The equity portion of the acquisition consideration will not be adjusted in the event of any change in our stock price.

The equity portion of the acquisition consideration consists of an aggregate of up to 63,474,791 shares of our common stock and common units, subject to reduction as set forth in the purchase agreement. The number of shares of our common stock to be delivered to the seller parties upon completion of the acquisition will be equal to approximately 9.8% of the total issued and outstanding shares of our common stock (excluding any restricted shares of our common stock then issued and outstanding but, for purposes of such calculation, after giving effect to the issuance of the common stock to the seller parties) on the close of business two business days immediately prior to the date of the consummation of the acquisition. The remainder of the equity consideration will consist of common units. The aggregate number of shares of common stock and common units will not be adjusted for changes in the market price of our common stock. Changes in the market price of our common stock, which may result from a variety of factors (many of which are beyond our control), will affect the value of the acquisition consideration that the seller parties will receive upon consummation of the acquisition. As a result, prior to the consummation of the acquisition, you will not know the exact value of the shares of common stock and the common units that the seller parties will receive upon the consummation of the acquisition.

Certain of the Target Properties are subject to ground leases, pursuant to which the ground lessors have consent rights that if not granted may prevent us from acquiring such properties.

Certain of the Target Properties are subject to ground leases with unaffiliated third party ground lessors, pursuant to which such lessors have consent rights that, if not granted or waived, may prevent us from acquiring such properties. There can be no assurance that the seller parties will be able to obtain the consents required to consummate the transfer of such properties to us pursuant to the purchase agreement. In the event that we are unable to acquire the properties that are subject to ground leases due to a failure to obtain ground lessor consent,

the total consideration to be paid in the acquisition will be adjusted; however, such reduction in consideration may not be commensurate with the lost actual or anticipated benefits of acquiring such properties. In addition, if we are unable to acquire one or more of the Target Properties for the reasons described above, we may not realize the operating efficiencies that may otherwise be achieved and the overall size, geographic footprint, tenant mix and other attributes of the Target Portfolio.

The Target Properties may be subject to environmental liabilities for which we may become responsible.

Certain of the Target Properties subject to ground leases with Stanford have been subject to environmental investigation and remediation for many years, including soil removal, groundwater remediation and monitoring. These activities are ongoing at certain sites and will continue into the foreseeable future. At other sites, only monitoring is required. At present, these activities do not interfere with the leasing and operation of the properties but could do so if agency requirements or remediation requirements change. In addition, these activities could cause additional expense if the properties are redeveloped or renovated by us. The parties responsible for remediation are typically former tenants that engaged in electronic manufacturing and caused the release of chlorinated compounds and other contaminants. If the responsible parties become unable to meet these remediation obligations, it is possible that we could become responsible for them.

Screening for vapor intrusion is underway at several of the Target Properties. These screenings are monitored by either the San Francisco Regional Water Quality Control Board or the Department of Toxic Substances Control and are the responsibility of prior tenants. If the responsible parties are unable to meet any required remediation obligations, we could become responsible for them. In addition, we could be the subject of claims associated with indoor air exposure. Further, certain of the Target Properties have known asbestos-containing materials. We could incur abatement costs associated with testing for and remediating any asbestos issues and could be subject of claims associated with exposure to asbestos.

We cannot assure you that costs or liabilities incurred as a result of environmental issues will not affect our ability to make distributions to our stockholders or that such costs or other remedial measures will not have an adverse effect on our financial condition, results of operations, cash flow and the per share trading price of our common stock. If we do incur material environmental liabilities in the future, we may face significant remediation costs, and we may find it difficult to sell any affected properties.

Upon completion of the acquisition, Blackstone is expected to beneficially own 9.8% of our outstanding common stock and an approximate 44.1% interest in us on a fully diluted basis (including common units). Consequently, Blackstone may be able to significantly influence the outcome of matters submitted for stockholder action, including approval of significant corporate transactions, such as amendments to our governing documents, business combinations, consolidations and mergers. In addition, concurrently with the consummation of the acquisition, the partnership agreement of our operating partnership will be amended to provide that holders of common units will be entitled to vote to approve the consummation of certain change of control and other transactions that are required to be approved by our stockholders. The right of the holders of common units to vote to approve any such transactions will remain in effect for so long as Blackstone owns at least 9.8% of the aggregate number of shares of common stock and common units that Blackstone receives as the equity consideration in the acquisition.

Further, under the purchase agreement, we have agreed to increase the size of our board of directors from nine to twelve members, and if the acquisition is consummated, Blackstone will have the right to designate three of our director nominees for so long Blackstone beneficially owns more than 50% of the total number of shares of our common stock and common units to be acquired as the equity consideration in the acquisition. This right

to designate director nominees (i) will be reduced to two directors on the first date on which Blackstone beneficially owns greater than or equal to 30% but less than or equal to 50% of the total number of shares of our common stock and common units to be acquired as the equity consideration in the acquisition, (ii) will be reduced to one director on the first date on which Blackstone beneficially owns greater than or equal to 15% but less than 30% of the total number of shares of our common stock and common units to be acquired as the equity consideration in the acquisition, and (iii) will cease altogether on the date on which Blackstone beneficially owns less than 15% of the total number of shares of our common stock and common units to be acquired as the equity consideration in the acquisition. For so long as Blackstone has the right to designate at least two director nominees, they will also be entitled to appoint one such nominee then serving on the board of directors to serve on each committee of the board of directors (other than certain specified committees). As a result, Blackstone will have substantial influence on us and could exercise its influence in a manner that conflicts with the interests of other stockholders. The presence of a significant stockholder and the addition to the board of directors of its nominees may also have the effect of making it more difficult for a third party to acquire us or for our board of directors to discourage a third party form seeking to acquire us.

We will incur significant additional indebtedness in order to finance the acquisition of the Target Properties, which could adversely affect us, including by decreasing our business flexibility and increasing our interest expense.

Our consolidated indebtedness as of September 30, 2014 was approximately $917.2 million (before loan premium), which included $484.6 million of variable rate debt, of which $156.5 million is subject to interest rate agreements. We may incur significant additional debt to finance future acquisition and development activities. As of September 30, 2014, we had approximately $300.0 million of total capacity under our revolving credit facility, of which $95.0 million had been drawn, and our term loan facility was fully drawn. After giving effect to the acquisition and the anticipated incurrence of indebtedness in connection therewith (and assuming the acquisition were to be consummated on September 30, 2014), our indebtedness would be approximately $2,024.2 million (before loan premium), assuming we finance approximately $1,149.6 million of the cash consideration for the acquisition (before closing costs, prorations and credits) with indebtedness, after applying the expected net proceeds from the First Financial disposition, the 1455 Market Street Joint Venture and this offering. We will have substantially increased indebtedness following completion of the acquisition, which could have the effect, among other things, of reducing our flexibility to respond to changing business and economic conditions and increasing our interest expense. We will also incur various costs and expenses associated with the financing of the acquisition. The amount of cash required to pay interest on our increased indebtedness levels following consummation of the acquisition and thus the demands on our cash resources will be greater than the amount of cash flows required to service our indebtedness prior to the acquisition. The increased levels of indebtedness following consummation of the acquisition could (i) reduce access to capital, (ii) increase borrowing costs generally or for any additional indebtedness, (iii) reduce funds available for working capital, capital expenditures, acquisitions and other general corporate purposes, (iv) create competitive disadvantages for us relative to other companies with lower debt levels, (v) reduce the amount of cash available to pay dividends on our common stock and (vi) increase our vulnerability to general adverse economic and industry conditions. If we do not achieve the expected benefits and cost savings from the acquisition, our ability to service our indebtedness may be adversely impacted.

Certain of the indebtedness that may be incurred in connection with the acquisition could bear interest at variable interest rates. If interest rates increase, such variable rate debt would create higher debt service requirements, which could adversely affect our cash flows, our ability to pay principal and interest on our debt, our cost of refinancing our debt when it becomes due and our ability to make or sustain distributions to stockholders. Additionally, if we choose to hedge our interest rate risk, we cannot guarantee that the hedge will be effective or that the hedging counterparty will meet its obligations to us.

Moreover, we may be required to raise substantial additional financing to fund working capital, capital expenditures, acquisitions or other general corporate requirements. Our ability to arrange additional financing

will depend on, among other factors, our financial position and performance, as well as prevailing market conditions and other factors beyond our control. We cannot assure you that we will be able to obtain additional financing on terms acceptable to us or at all.

Our future results will suffer if we do not effectively integrate the Target Properties and any retained employees following the acquisition.

Following the acquisition, we may be unable to integrate successfully the Target Properties and any retained employees and realize the anticipated benefits of the acquisition or do so within the anticipated timeframe. The integration process could distract management, disrupt our ongoing business or result in inconsistencies in our operations, services, standards, controls, procedures and policies, any of which could adversely affect our ability to maintain relationships with our tenants, lenders, joint venture partners, vendors and employees or to achieve all or any of the anticipated benefits of the acquisition.

The per share trading price of our common stock may decline as a result of the acquisition.

The per share trading price of our common stock may decline as a result of the acquisition if we do not achieve the perceived benefits of the acquisition as rapidly or to the extent anticipated by financial or industry analysts or the effect of the acquisition on our financial results is not consistent with the expectations of financial or industry analysts. In addition, if the acquisition is consummated, we will own and operate a significantly larger portfolio than at present, with a different mix of properties, geographic concentration, risks and liabilities. Our common stockholders may not wish to continue to invest in us if the acquisition is consummated or for other reasons may wish to dispose of some or all of their investment. If, following the consummation of the acquisition, there is selling pressure on our common stock that exceeds demand at the per share trading price, the per share trading price of our common stock could decline. Further, the acquisition is expected to be dilutive to adjusted funds from operations per share in 2015, which could cause the per share trading price of our common stock to decline.

In addition to the agreements governing our revolving credit facility and term loan facility, the agreements that will govern the indebtedness to be incurred in connection with the acquisition are expected to contain various covenants imposing restrictions on us and certain of our subsidiaries that may affect our ability to operate our businesses.

The agreements governing our revolving credit facility and term loan facility prohibit us, and the agreements that will govern the indebtedness to be incurred in connection with the acquisition are expected to prohibit us, from making certain restricted payments, subject to certain significant exceptions. Under these facilities, our distributions may not exceed the greater of (i) 95.0% of our funds from operations, or (ii) the amount required for us to continue to qualify and maintain our status as a REIT and to avoid the imposition of income and excise taxes. As a result, if we do not generate sufficient funds from operations (as defined in these facilities) during the 12 months preceding any common stock dividend payment date, we would not be able to pay dividends to our common stockholders consistent with our past practice without causing a default under these facilities. In the event of a default under these facilities, we would be unable to borrow under these facilities and any amounts we have borrowed thereunder could become due and payable.

The agreements governing our revolving credit facility and term loan facility contain, and the agreements that will govern the indebtedness to be incurred in connection with the acquisition are expected to contain, various affirmative and negative covenants that may, subject to certain significant exceptions, restrict our ability and that of certain of our subsidiaries to, among other things, have liens on property, incur additional indebtedness, make loans, advances or other investments, make non-ordinary course asset sales, and/or merge or consolidate with any other person or sell or convey certain of our assets to any one person. In addition, the agreements governing our revolving credit facility and term loan facility contain, and the agreements that will govern the debt financing are expected to contain, financial covenants that will require us to maintain certain

financial ratios. Our ability to comply with these provisions may be affected by events beyond our control. Failure to comply with these covenants could result in an event of default, which, if not cured or waived, could accelerate our repayment obligations.

We cannot assure you that we will be able to continue paying dividends at the current rate.

We intend to make distributions each taxable year equal to at least 90% of our taxable income and intend to pay regular quarterly dividends to our common stockholders. However, our common stockholders may not receive the same quarterly dividends following the acquisition for various reasons, including the following:

The risks associated with implementing our long-term business plan and strategy following the acquisition may be different from the risks related to our business with respect to our existing property portfolio.

Our ability to execute our long-term business plan and strategy following the acquisition of the Target Properties may be different from the execution risks related to our business solely with respect to our existing real property portfolio. Such risks may include unforeseen delays or an inability to renew leases, lease vacant spaces or re-let spaces as leases expire. In addition, we may be required to make rent or other concessions and/or incur significant capital expenditures to improve both our existing properties as well as the Target Properties in order to retain and attract tenants, causing our financial condition, results of operation, cash flow and per share trading price of our common stock to be adversely affected.

The unaudited condensed consolidated pro forma financial statements incorporated by reference in this prospectus supplement and the accompanying prospectus is presented for illustrative purposes only and does not purport to be indicative of what our actual financial condition or results of operations would have been had the 1455 Market Street Joint Venture, the acquisition of the Target Properties and related financing and the disposition of First Financial occurred on the dates indicated.

The unaudited condensed consolidated pro forma financial statements incorporated by reference in this prospectus supplement and the accompanying prospectus that give effect to the 1455 Market Street Joint Venture, the acquisition of the Target Properties and related financing and the disposition of First Financial are based on numerous assumptions and estimates underlying the adjustments described in the accompanying notes, which are based on available information and assumptions that our management considers reasonable. In addition, such unaudited condensed consolidated pro forma financial statements do not reflect adjustments for other developments with our business or the Target Portfolio after September 30, 2014. As a result, the pro forma consolidated financial statements do not purport to represent our financial condition that would have actually occurred had the 1455 Market Street Joint Venture, the acquisition of the Target Properties and related financing and the disposition of First Financial occurred on September 30, 2014, represent the results of our operations that would have actually occurred had the 1455 Market Street Joint Venture, the acquisition of the Target Properties and related financing and the disposition of First Financial occurred on January 1, 2013 or project our financial position or results of operations as of any future date or for any future period, as applicable.

The per share trading price and trading volume of our common stock may be volatile following this offering.

The per share trading price of our common stock may be volatile. In addition, the trading volume in our common stock may fluctuate and cause significant price variations to occur. If the per share trading price of our

common stock declines significantly, you may be unable to resell your shares at or above the purchase price. We cannot assure you that the per share trading price of our common stock will not fluctuate or decline significantly in the future.

Some of the factors that could negatively affect our share price or result in fluctuations in the price or trading volume of our common stock include:

In the past, securities class action litigation has often been instituted against companies following periods of volatility in the price of their common stock. This type of litigation could result in substantial costs and divert our management’s attention and resources, which could have an adverse effect on our financial condition, results of operations, cash flow and per share trading price of our common stock.

Our common stock is ranked junior to our series B preferred stock with respect to dividends and upon dissolution. In certain circumstances following a change of control of our company, holders of our series B

preferred stock will be entitled to receive dividends at the increased rate of 12.375% per annum of the liquidation preference per share of our series B preferred stock and we will have the option to redeem our series B preferred stock for cash at $25.00 per share plus accrued and unpaid dividends. Holders of our common stock are not entitled to preemptive rights or other protections against dilution. We may in the future attempt to increase our capital resources by making additional offerings of equity securities, including additional classes or series of preferred stock, which would likely have preferences with respect to dividends or upon dissolution that are senior to our common stock. Because our decision to issue securities in any future offering will depend on market conditions and other factors beyond our control, we cannot predict or estimate the amount, timing or nature of any such future offering. Thus, our common stockholders bear the risk of our future offerings reducing the per share trading price of our common stock and diluting their interest in us.

Affiliates of the underwriters may receive benefits in connection with this offering.

Affiliates of Wells Fargo Securities, LLC, Merrill Lynch, Pierce, Fenner & Smith Incorporated, Barclays Capital Inc., Morgan Stanley & Co. LLC, KeyBanc Capital Markets Inc. and RBC Capital Markets, LLC (underwriters in this offering) are lenders under our revolving credit facility. To the extent that we use a portion of the net proceeds of this offering to repay borrowings outstanding under our revolving credit facility, these affiliates will receive their proportionate shares of any amount of our revolving credit facility that is repaid with the net proceeds of this offering. Wells Fargo Securities, LLC provided financial advisory services in connection with the acquisition of the Target Portfolio in exchange for a fee, the majority of which is contingent upon consummation of the transaction. Goldman, Sachs & Co. provided financial advisory services to Blackstone in connection with the acquisition of the Target Portfolio in exchange for a fee. Affiliates of Wells Fargo Securities, LLC, Merrill Lynch, Pierce, Fenner & Smith Incorporated and Goldman, Sachs & Co. have committed to provide part of the financing involved in the acquisition of the Target Properties. These transactions create potential conflicts of interest because the underwriters have an interest in the successful completion of this offering beyond the underwriting discounts they will receive. These interests may influence the decision regarding the terms and circumstances under which the offering is completed.

Market interest rates may have an effect on the value of our common stock.

One of the factors that will influence the per share trading price of our common stock will be the dividend yield on our common stock (as a percentage of the price of our common stock) relative to market interest rates. An increase in market interest rates, which are currently at low levels relative to historical rates, may lead prospective purchasers of shares of our common stock to expect a higher dividend yield and higher interest rates would likely increase our borrowing costs and potentially decrease funds available for distribution. Thus, higher market interest rates could cause the per share trading price of our common stock to decrease.

The number of shares of our common stock available for future issuance or sale could adversely affect the per share trading price of our common stock.

We cannot predict whether future issuances or sales of shares of our common stock or the availability of shares of our common stock for resale in the open market will decrease the per share trading price of our common stock. The issuance of substantial numbers of shares of our common stock in the public market, or upon exchange of common units, or the perception that such issuances might occur could adversely affect the per share trading price of our common stock. The per share trading price of our common stock may decline significantly upon the sale or registration of additional shares of our common stock pursuant to registration rights to be granted to the seller parties upon the consummation of the acquisition or granted in connection with our initial public offering, our 2010 private placement and our 2011 private placement, which registration rights also cover any shares of common stock that certain funds affiliated with Farallon Capital Management, L.L.C., or the Farallon Funds, purchased in subsequent offerings prior to June 29, 2012, including our May 2012 public offering of common stock.

None of the shares of our common stock or common units that will be issued to the seller parties upon consummation of the acquisition will initially be registered under the Securities Act, and such shares of our

common stock and common units will only be able to be resold pursuant to an effective registration statement or an applicable exemption from registration under federal and state securities laws. Upon the consummation of the acquisition, we will enter into a registration rights agreement with the seller parties or their designated affiliates receiving the equity consideration, pursuant to which we will agree to register for resale 63,474,791 shares of common stock, representing the shares of common stock to be issued to the seller parties or such designated affiliates and any shares of common stock issuable upon the exchange of common units issued in the acquisition. In addition, if we propose to register the offer and sale of our common stock under the Securities Act, in connection with the public offering of such common stock, the seller parties will be entitled to certain “piggyback” registration rights allowing them to include their shares in such registration, subject to certain marketing and other limitations.

Upon the completion of the acquisition, the seller parties will enter into a stockholders agreement, or the stockholders agreement, with us and our operating partnership, pursuant to which they will agree generally to not to transfer or sell any shares of common stock or common units to be issued in connection with the acquisition prior to November 1, 2015. The restrictions on transfer and sale contained in the stockholders agreement will terminate with respect to 50% of the total number of shares of our common stock and common units to be issued to the seller parties on November 1, 2015 and with respect to the remaining 50% of such shares of our common stock and common units on March 1, 2016. In the event that the seller parties elect to terminate their right to designate nominees for election as directors to our board of directors (i) prior to November 1, 2015, the restriction on transfer and sale contained in the stockholders agreement will terminate on November 1, 2015 with respect to all shares of our common stock and common units issued to the seller parties in connection with the acquisition, or (ii) after November 1, 2015 but before March 1, 2016, any remaining restrictions on transfer or sale will terminate on the earlier of March 1, 2016 or thirty days following the seller parties’ election.

In addition, we have entered into a registration rights agreement with the Farallon Funds pursuant to which we are obligated, subject to certain exceptions, to maintain an effective registration statement providing for the resale of 10,535,534 shares of our common stock on behalf of the Farallon Funds. These 10,535,534 shares of our common stock represent approximately 13.5% of our outstanding shares of our common stock (or approximately 13.1% of our outstanding shares of our common stock and common units held by limited partners of our operating partnership) following the consummation of this offering (assuming no exercise by the underwriters’ of their option to purchase additional shares). As a result, a substantial number of additional shares may be sold pursuant to the registration rights granted to the seller parties and the Farallon Funds. The sale of such shares by the seller parties and/or the Farallon Funds, or the perception that such sales may occur, could materially and adversely affect the per share trading price of our common stock.

The exercise of the underwriters’ option to purchase additional shares, the exchange of common units for common stock, the exercise of any options or the vesting of any restricted stock granted to certain directors, executive officers and other employees under our equity incentive plan, the issuance of our common stock or common units in connection with future property, portfolio or business acquisitions, or, if we close the acquisition, the resale, or perception of a potential resale, of all or a substantial portion of the shares of our common stock issued in the acquisition or shares of common stock issuable upon exchange of common units issued in the acquisition, could have an adverse effect on the per share trading price of our common stock. Moreover, the existence of common units, options, shares of our common stock reserved for issuance as restricted shares of our common stock or upon exchange of common units may adversely affect the terms upon which we may be able to obtain additional capital through the sale of equity securities. Future issuances of shares of our common stock may also be dilutive to existing stockholders.

Future offerings of debt securities, which would be senior to our common stock upon liquidation, and/or preferred equity securities which may be senior to our common stock for purposes of dividend distributions or upon liquidation, may adversely affect the per share trading price of our common stock.

In the future, we may attempt to increase our capital resources by making additional offerings of debt or equity securities (or causing our operating partnership to issue debt or equity securities), including medium-term notes, senior or subordinated notes and additional classes or series of preferred stock or preferred units. Upon liquidation, holders of our debt securities and shares of preferred stock or preferred units of partnership interest in our operating partnership and lenders with respect to other borrowings would be entitled to receive our available assets prior to distribution to the holders of our common stock. Additionally, any convertible or exchangeable securities that we issue in the future may have rights, preferences and privileges more favorable than those of our common stock and may result in dilution to owners of our common stock. Holders of our common stock are not entitled to preemptive rights or other protections against dilution. Any shares of preferred stock we issue or preferred units our operating partnership issues in the future could have a preference on liquidating distributions or a preference on dividend payments that could limit our ability pay dividends to the holders of our common stock. Because our decision to issue securities in any future offering will depend on market conditions and other factors beyond our control, we cannot predict or estimate the amount, timing or nature of any such future offering. Thus, our stockholders bear the risk of our future offerings reducing the per share trading price of our common stock and diluting their interest in us.

Our ability to pay dividends is limited by the requirements of Maryland law.

Our ability to pay dividends on our common stock is limited by the laws of Maryland. Under applicable Maryland law, a Maryland corporation generally may not make a distribution if, after giving effect to the distribution, the corporation would not be able to pay its debts as the debts become due in the usual course of business or the corporation’s total assets would be less than the sum of its total liabilities plus, unless the corporation’s charter permits otherwise, the amount that would be needed, if the corporation were dissolved at the time of the distribution, to satisfy the preferential rights upon dissolution of stockholders whose preferential rights are superior to those receiving the distribution. Accordingly, we generally may not make a distribution on our common stock if, after giving effect to the distribution, we would not be able to pay our debts as they become due in the usual course of business or our total assets would be less than the sum of our total liabilities plus, unless the terms of such class or series provide otherwise (and the terms of our series B preferred stock do not so provide otherwise), the amount that would be needed to satisfy the preferential rights upon dissolution of the holders of shares of any class or series of preferred stock (including our series B preferred stock) then outstanding, if any, with preferences upon dissolution senior to those of our common stock.

Our operating partnership intends to use the net proceeds from this offering to fund a portion of the acquisition of the Target Portfolio as described under “Prospectus Supplement Summary—Recent Developments—Target Portfolio Acquisition.” If the acquisition of the Target Portfolio is not consummated, our operating partnership intends to use the net proceeds for development and redevelopment activities, potential acquisition opportunities and/or for general corporate purposes. Pending these applications, our operating partnership intends to use the net proceeds to temporarily repay borrowings outstanding under our revolving credit facility and/or invest in interest-bearing accounts and short-term, interest-bearing securities in a manner that is consistent with our intention to continue to qualify as a REIT.

As of September 30, 2014, we had $95.0 million outstanding under our revolving credit facility and our term loan facility was fully drawn. As of January 12, 2015, we have approximately $130.0 million outstanding under our revolving credit facility. Our revolving credit facility currently bears interest at a rate per annum equal to either LIBOR plus 115 to 155 basis points or a specified base rate plus 15 to 55 basis points, depending on our leverage ratio, and has a maturity date of September 23, 2018 (which maturity may be extended for an additional year at our option subject to certain conditions). If we obtain a credit rating for our senior unsecured long-term indebtedness, we may make an irrevocable election to change the interest rate for our revolving credit facility to a rate equal to either LIBOR plus 87.5 to 165 basis points per annum or the specified base rate plus 0 to 65 basis points per annum, depending on the credit rating. Any borrowings under our revolving credit facility that are repaid with net proceeds from this offering may be reborrowed, subject to customary conditions.

The following table sets forth our actual cash and cash equivalents and consolidated capitalization as of September 30, 2014:

You should read this table in conjunction with “Use of Proceeds” in this prospectus supplement and the consolidated financial statements and related notes and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our Annual Report on Form 10-K for the year ended December 31, 2013, our Quarterly Report on Form 10-Q for the quarter ended September 30, 2014 and our Current Report on Form 8-K filed with the Securities and Exchange Commission on January 12, 2015, each of which is incorporated herein by reference.

No adjustments have been made to reflect our normal course operations or other developments with our business after September 30, 2014. As a result, the pro forma and as adjusted information provided below is not indicative of our actual cash and cash equivalents position or consolidated capitalization as of any date.

Wells Fargo Securities, LLC, Merrill Lynch, Pierce, Fenner & Smith Incorporated and Goldman, Sachs & Co. are acting as representatives of each of the underwriters named below. Subject to the terms and conditions set forth in an underwriting agreement among us, our operating partnership and the underwriters, we have agreed to sell to the underwriters, and each of the underwriters has agreed, severally and not jointly, to purchase from us, the number of shares of common stock set forth opposite its name below.

Subject to the terms and conditions set forth in the underwriting agreement, the underwriters have agreed, severally and not jointly, to purchase all of the shares of common stock sold under the underwriting agreement if any of these shares are purchased. If an underwriter defaults, the underwriting agreement provides that the purchase commitments of the nondefaulting underwriters may be increased or the underwriting agreement may be terminated.

We and our operating partnership have agreed to indemnify the underwriters against the following:

In addition, we and our operating partnership are obligated to contribute to payments the underwriters may be required to make in respect of those liabilities if indemnification is not permitted.

The underwriters are offering the shares of common stock, subject to prior sale, when, as and if issued to and accepted by them, subject to approval of legal matters by their counsel, including the validity of the shares of common stock, and other conditions contained in the underwriting agreement, such as the receipt by the underwriters of officer’s certificates and legal opinions. The underwriters reserve the right to withdraw, cancel or modify offers to the public and to reject orders in whole or in part.

The representatives have advised us that the underwriters propose initially to offer the shares of common stock to the public at the public offering price set forth on the cover page of this prospectus supplement and to dealers at that price less a concession not in excess of $0.762 per share. After the initial offering, the public offering price, concession or any other term of the offering may be changed.

The following table shows the public offering price, underwriting discount and proceeds before expenses to us. The information assumes either no exercise or full exercise by the underwriters of their option to purchase additional shares.

The expenses of the offering, including the filing fees and reasonable fees and disbursements of counsel to the underwriters in connection with FINRA filings, but not including the underwriting discount, are estimated at approximately $400,000 and are payable by us.

We have granted an option to the underwriters to purchase up to 1,650,000 additional shares of common stock at the public offering price, less the underwriting discount. The underwriters may exercise this option for 30 days from the date of this prospectus supplement. If the underwriters exercise this option, each will be obligated, subject to conditions contained in the underwriting agreement, to purchase a number of additional shares proportionate to that underwriter’s initial amount reflected in the above table.

Pursuant to the underwriting agreement, we, our executive officers, our directors and the Farallon Funds have agreed not to sell or transfer any shares of common stock or any securities convertible into or exercisable or exchangeable for common stock (including units in our operating partnership), for 60 days after the date of this prospectus supplement (provided, that the Farallon Funds have the right to (i) sell shares of common stock representing up to 25% of the aggregate number of shares of our common stock and common units issued to the Farallon Funds in the formation transactions related to our initial public offering and the 2010 private placement pursuant to a demand registration statement or (ii) to distribute such amount of shares to their limited partners, members or stockholders) without first obtaining the written consent of Wells Fargo Securities, LLC and Merrill Lynch, Pierce, Fenner & Smith Incorporated. Specifically, we and these other persons have agreed not to directly or indirectly:

The restrictions described in the immediately preceding paragraph do not apply to: (A) with respect to us, (1) the sale of shares to the underwriters, (2) any shares of our common stock issued or options to purchase our

common stock granted pursuant to the Hudson Pacific Properties, Inc. and Hudson Pacific Properties, L.P. 2010 Incentive Award Plan, as amended, or the Hudson Pacific Properties, Inc. Director Stock Plan, (3) any shares of our common stock issued pursuant to any non-employee director stock plan or dividend reinvestment plan referred to in this prospectus supplement (including the documents incorporated herein by reference), (4) shares of our common stock transferred in accordance with Article VI of our charter, (5) shares of our common stock, in the aggregate not to exceed 10% of the number of shares of common stock outstanding, issued in connection with other acquisitions of real property or real property companies, provided, in the case of this clause (5), that each acquirer agrees to similar restrictions, and (6) the filing of a registration statement on Form S-8 relating to the offering of securities in accordance with the terms of an equity incentive plan; and (B) with respect to our officers, our directors and the Farallon Funds, (1)(i) gifts or other dispositions by will or intestacy, (ii) transfers made to (x) limited partners, members, stockholders or affiliates or (y) any wholly-owned subsidiary, (iii) bona fide gifts, sales or other dispositions to (w) members of the transferor’s family, (x) affiliates of the transferor that are controlled by the transferor, or (y) a trust the beneficiaries of which are a limited liability company or a partnership owned exclusively by the transferor and/or members of the transferor’s family, or (iv) donations or transfer to charitable organizations, provided, in the case of this clause (1), that (a) the transferee agrees to similar restrictions, (b) no filing by any party under the Exchange Act shall be required or shall be voluntarily made in connection with such transfer or distribution, (c) each party shall agree to not voluntarily make any public announcement of the transfer or disposition, and (d) the transferor notifies Wells Fargo Securities, LLC and Merrill Lynch, Pierce, Fenner & Smith Incorporated at least three business days prior to the proposed disposition, and (2) transactions relating to shares of our common stock acquired by the transferor in the open market after completion of the offering; provided, however, that (a) any subsequent sale of the shares of our common stock acquired in the open market are not required to be reported in any public report or filing with the Securities and Exchange Commission, or otherwise and (ii) the transferor does not otherwise voluntarily effect any public filing or report regarding such sales.

This lock-up provision applies to common stock and to securities convertible into, or exchangeable or exercisable for common stock. It also applies to common stock owned now or acquired later by the person executing the agreement or for which the person executing the agreement later acquires the power of disposition.

Until the distribution of the shares of common stock is completed, the Securities and Exchange Commission’s rules may limit underwriters and selling group members from bidding for and purchasing our common stock. However, the representatives may engage in transactions that stabilize the price of the common stock, such as bids or purchases to peg, fix or maintain that price.

In connection with the offering, the underwriters may purchase and sell our common stock in the open market. These transactions may include short sales, purchases on the open market to cover positions created by short sales and stabilizing transactions. Short sales involve the sale by the underwriters of a greater number of shares than they are required to purchase in the offering. “Covered” short sales are sales made in an amount not greater than the underwriters’ option to purchase additional shares in the offering. The underwriters may close out any covered short position by either exercising their option to purchase additional shares or purchasing shares in the open market. In determining the source of shares to close out the covered short position, the underwriters will consider, among other things, the price of shares available for purchase in the open market as compared to the price at which they may purchase shares through their option. “Naked” short sales are sales in excess of their option to purchase additional shares. The underwriters must close out any naked short position by purchasing shares in the open market. A naked short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of our common stock in the open market after pricing that

could adversely affect investors who purchase in the offering. Stabilizing transactions consist of various bids for or purchases of shares of common stock made by the underwriters in the open market prior to the completion of the offering.

The underwriters may also impose a penalty bid. This occurs when a particular underwriter repays to the underwriters a portion of the underwriting discount received by it because the representatives have repurchased shares sold by or for the account of such underwriter in stabilizing or short covering transactions.

Similar to other purchase transactions, the underwriters’ purchases to cover the syndicate short sales may have the effect of raising or maintaining the market price of our common stock or preventing or retarding a decline in the market price of our common stock. As a result, the price of our common stock may be higher than the price that might otherwise exist in the open market.

Neither we nor any of the underwriters make any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of our common stock. In addition, neither we nor any of the underwriters make any representation that the representatives will engage in these transactions or that these transactions, once commenced, will not be discontinued without notice.

In connection with the offering, certain of the underwriters or securities dealers may distribute prospectuses by electronic means, such as e-mail. In addition, certain of the underwriters may facilitate Internet distribution for this offering to certain of their Internet subscription customers. These underwriters may allocate a limited number of shares for sale to its online brokerage customers. An electronic prospectus may be available on the Internet Web site maintained by certain underwriters. Other than any prospectus in electronic format, the information on an underwriter’s Web site is not part of this prospectus.

Some of the underwriters and their affiliates have engaged in, and may in the future engage in, investment banking and other commercial dealings in the ordinary course of business with us and/or our affiliates. They have received, or may in the future receive, customary fees and commissions for these transactions. An affiliate of Wells Fargo Securities, LLC acts as administrative agent, Wells Fargo Securities, LLC and Merrill Lynch, Pierce, Fenner and Smith Incorporated act as joint lead arrangers, affiliates of Merrill Lynch, Pierce, Fenner and Smith Incorporated and Barclays Capital Inc. act as joint syndication agents, an affiliate of KeyBanc Capital Markets Inc. acts as documentation agent, and affiliates of Wells Fargo Securities, LLC, Merrill Lynch, Pierce, Fenner & Smith Incorporated, Barclays Capital Inc., Morgan Stanley & Co. LLC, KeyBanc Capital Markets Inc. and RBC Capital Markets, LLC are lenders under our revolving credit facility and term loan facility. As described above under “Use of Proceeds,” our operating partnership intends to use a portion of the net proceeds from this offering to temporarily repay borrowings outstanding under our revolving credit facility. As a result, these affiliates will receive their proportionate share of any amount of our revolving credit facility that is repaid with the net proceeds of this offering to us. Wells Fargo Securities, LLC provided financial advisory services in connection with the acquisition of the Target Portfolio in exchange for a fee, the majority of which is contingent upon consummation of the transaction. Goldman, Sachs & Co. provided financial advisory services to Blackstone in connection with the acquisition of the Target Portfolio in exchange for a fee. Affiliates of Wells Fargo Securities, LLC, Merrill Lynch, Pierce, Fenner & Smith Incorporated and Goldman, Sachs & Co. have committed to provide the bridge loan. Proceeds from this offering will be used to reduce the amount of the bridge loan.

In addition, in the ordinary course of their business activities, the underwriters and their affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers. Such investments and securities activities may involve securities and/or instruments of ours or our affiliates.

Certain of the underwriters or their affiliates that have a lending relationship with us routinely hedge their credit exposure to us consistent with their customary risk management policies. Typically, such underwriters and their affiliates would hedge such exposure by entering into transactions which consist of either the purchase of credit default swaps or the creation of short positions in our securities. The underwriters and their affiliates may also make investment recommendations and/or publish or express independent research views in respect of such securities or financial instruments and may hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

On December 6, 2014, we entered into an asset purchase agreement, or the purchase agreement, with our operating partnership and certain affiliates of The Blackstone Group L.P., which we refer to collectively as the “seller parties,” pursuant to which our operating partnership and/or our other subsidiaries will acquire a portfolio of 26 high-quality office assets totaling approximately 8.2 million square feet and two development parcels in the San Francisco Peninsula and Silicon Valley from the seller parties in exchange for a combination of cash and equity consideration. Pursuant to the terms of the purchase agreement, effective upon consummation of the acquisition, (i) we, our operating partnership and the seller parties (or their designated affiliates) will enter into a stockholders agreement, (ii) we and the seller parties (or their designated affiliates) will enter into a registration rights agreement and (iii) we will enter into a Third Amended and Restated Limited Partnership Agreement of Hudson Pacific Properties, L.P., each as described in more detail in our Current Report on Form 8-K filed with the Securities and Exchange Commission on December 11, 2014, or the December 2014 8-K, which is incorporated herein by reference. For more information regarding this transaction and related documents, you should refer to the December 2014 8-K and the documents filed as exhibits thereto, which are incorporated herein by reference.

As of December 31, 2014, our portfolio included office properties, comprising an aggregate of approximately 5.5 million square feet, and media and entertainment properties, comprising approximately 0.9 million square feet of sound-stage, office and supporting production facilities. We also own undeveloped density rights for approximately 1,587,049 square feet of future development space. Our properties are concentrated in premier submarkets that have high barriers to entry with limited supply of land, high construction costs and rigorous entitlement processes.

We filed our articles of incorporation with the Maryland State Department of Assessments and Taxation on November 9, 2009.

Our principal executive offices are located at 11601 Wilshire Boulevard, Sixth Floor, Los Angeles, California 90025, and our telephone number is (310) 445-5700.

The occurrence of any of these risks might cause you to lose all or part of your investment in the offered securities.

Failure to qualify as a REIT would have significant adverse consequences to us and the value of our securities.

We have elected to be taxed as a REIT for federal income tax purposes commencing with our taxable year ended December 31, 2010. We believe that we have operated in a manner that has allowed us to qualify as a REIT for federal income tax purposes commencing with such taxable year, and we intend to continue operating in such manner. We have not requested and do not plan to request a ruling from the Internal Revenue Service, or IRS, that we qualify as a REIT, and the statements herein are not binding on the IRS or any court. Therefore, we cannot assure you that we have qualified as a REIT, or that we will remain qualified as such in the future. If we lose our REIT status, we will face serious tax consequences that would substantially reduce the funds available for distribution to you for each of the years involved because:

Any such corporate tax liability could be substantial and would reduce our cash available for, among other things, our operations and distributions to stockholders. In addition, if we fail to qualify as a REIT, we would not be required to make distributions to our stockholders. As a result of all these factors, our failure to qualify as a REIT also could impair our ability to expand our business and raise capital, and could materially and adversely affect the value of our securities.

Qualification as a REIT involves the application of highly technical and complex Code provisions for which there are only limited judicial and administrative interpretations. The complexity of these provisions and of the applicable Treasury regulations that have been promulgated under the Code, or the Treasury Regulations, is greater in the case of a REIT that, like us, holds its assets through a partnership. The determination of various factual matters and circumstances not entirely within our control may affect our ability to qualify as a REIT. In order to qualify as a REIT, we must satisfy a number of requirements, including requirements regarding the ownership of our stock and requirements regarding the composition of our assets and our gross income. Also, we must make distributions to stockholders aggregating annually at least 90% of our net taxable income, excluding net capital gains. We own and may acquire direct or indirect interests in one or more entities that have elected or will elect to be taxed as REITs under the Code (each, a “Subsidiary REIT”). A Subsidiary REIT is subject to the various REIT qualification requirements and other limitations described herein that are applicable to us. If a Subsidiary REIT were to fail to qualify as a REIT, then (i) that Subsidiary REIT would become subject to federal income tax, (ii) shares in such Subsidiary REIT would cease to be qualifying assets for purposes of the asset tests applicable to REITs, and (iii) it is possible that we would fail certain of the asset tests applicable to REITs, in

which event we would fail to qualify as a REIT unless we could avail ourselves of certain relief provisions. In addition, legislation, new regulations, administrative interpretations or court decisions may materially adversely affect our investors, our ability to qualify as a REIT for federal income tax purposes or the desirability of an investment in a REIT relative to other investments.

Even if we qualify as a REIT for federal income tax purposes, we may be subject to some federal, state and local income, property and excise taxes on our income or property and, in certain cases, a 100% penalty tax, in the event we sell property as a dealer. In addition, our taxable REIT subsidiaries are subject to tax as regular corporations in the jurisdictions in which they operate.

If our operating partnership failed to qualify as a partnership for federal income tax purposes, we would cease to qualify as a REIT and suffer other adverse consequences.

We believe that our operating partnership is properly treated as a partnership for federal income tax purposes. As a partnership, our operating partnership is not subject to federal income tax on its income. Instead, each of its partners, including us, is allocated, and may be required to pay tax with respect to, its share of our operating partnership’s income. We cannot assure you, however, that the IRS will not challenge the status of our operating partnership or any other subsidiary partnership in which we own an interest as a partnership for federal income tax purposes, or that a court would not sustain such a challenge. If the IRS were successful in treating our operating partnership or any such other subsidiary partnership as an entity taxable as a corporation for federal income tax purposes, we would fail to meet the gross income tests and certain of the asset tests applicable to REITs and, accordingly, we would likely cease to qualify as a REIT. Also, the failure of our operating partnership or any subsidiary partnerships to qualify as a partnership would cause it to become subject to federal and state corporate income tax, which could reduce significantly the amount of cash available for debt service and for distribution to its partners, including us.

The tax imposed on REITs engaging in “prohibited transactions” may limit our ability to engage in transactions that would be treated as sales for federal income tax purposes.

A REIT’s net income from prohibited transactions is subject to a 100% penalty tax. In general, prohibited transactions are sales or other dispositions of property, other than foreclosure property, held primarily for sale to customers in the ordinary course of business. Although we do not intend to hold any properties that would be characterized as held for sale to customers in the ordinary course of our business, such characterization is a factual determination and we cannot assure you that the IRS would agree with our characterization of our properties or that we will always be able to make use of the available safe harbors, which, if met, would prevent any such sales from being treated as prohibited transactions.

We intend to use the net proceeds from the sale of the securities as set forth in the applicable prospectus supplement. We will not receive any proceeds from the sale of common stock by the selling securityholders.

Our ratios of earnings to fixed charges and earnings to fixed charges and preferred dividends for the periods indicated are as follows:

Our ratios of earnings to fixed charges are computed by dividing earnings by fixed charges. Our ratios of earnings to fixed charges and preferred dividends are computed by dividing earnings by the sum of fixed charges and preferred dividends. For these purposes, “earnings” consist of net income (loss) plus fixed charges. Net income (loss) is computed in accordance with in accordance with U.S. generally accepted accounting principles, or GAAP, and includes such non-cash items as real estate depreciation and amortization, amortization of above (below) market rents, and amortization of deferred financing costs and loan premium. Net income (loss) in 2010 also includes one-time transactional costs relating to our initial public offering and related formation transactions and acquisitions subsequent to our initial public offering. “Fixed charges” consist of interest expense, capitalized interest and amortization of deferred financing fees and loan premium, whether expensed or capitalized, interest within rental expense and preference security dividend requirements of consolidated subsidiaries. Interest income is not included in this computation. “Preferred dividends” consist of the amount of pre-tax earnings required to make distributions on our operating partnership’s series A preferred units and pay dividends on our series B preferred stock.

The computation of ratio of earnings to fixed charges indicates that earnings were inadequate to cover fixed charges on the basis of our historical financial statements by approximately $7.0 million, $6.4 million, $2.4 million, $2.8 million, and $1.1 million for the years ended December 31, 2013, 2012, 2011, 2010 and 2009, respectively.

The computation of ratio of earnings to fixed charges and preferred dividends indicates that earnings were inadequate to cover fixed charges and preferred dividends on the basis of our historical financial statements by approximately $19.9 million, $19.3 million, $10.5 million, $3.6 million and $1.1 million for the years ended December 31, 2013, 2012, 2011, 2010 and 2009, respectively.

This prospectus describes the general terms of our common stock. For a more detailed description of these securities, you should read the applicable provisions of the Maryland General Corporation Law, or MGCL, and our charter and bylaws. When we offer to sell a particular class or series of stock, we will describe the specific terms of such class or series in a prospectus supplement. Accordingly, for a description of the terms of any class or series of stock, you must refer to both the prospectus supplement relating to that class or series and the description of stock in this prospectus. To the extent the information contained in the prospectus supplement differs from this summary description, you should rely on the information in the prospectus supplement.

Our charter provides that we may issue up to 490 million shares of common stock, $0.01 par value per share, or common stock. Our charter authorizes our board of directors, with the approval of a majority of the entire board and without any action by our stockholders, to amend our charter to increase or decrease the aggregate number of shares of stock or, subject to the rights of holders of our 8.375% series B cumulative redeemable preferred stock, $0.01 par value per share, or our series B preferred stock, and any other class or series of our stock, the number of shares of stock of any class or series that we have the authority to issue. As of January 12, 2015, 66,508,003 shares of our common stock are issued and outstanding, and 5,800,00 shares of our series B preferred stock are outstanding.

Under Maryland law, stockholders generally are not personally liable for our debts or obligations solely as a result of their status as stockholders.

Subject to the preferential rights of holders of series B preferred stock and any other class or series of our stock, and to the provisions of our charter regarding the restrictions on ownership and transfer of our stock, holders of shares of our common stock are entitled to receive dividends and other distributions on such shares if, as and when authorized by our board of directors out of funds legally available therefor and declared by us, and to share ratably in the assets of our company legally available for distribution to our stockholders in the event of our liquidation, dissolution or winding up, after payment or establishment of reserves for all known debts and liabilities of our company.

Subject to the provisions of our charter regarding the restrictions on ownership and transfer of our stock and except as may otherwise be specified in the terms of any class or series of our stock (including our series B preferred stock), each outstanding share of our common stock entitles the holder to one vote on all matters submitted to a vote of stockholders, including the election of directors, and the holders of shares of our common stock will possess the exclusive voting power. There is no cumulative voting in the election of our directors. In uncontested elections, directors are elected by the affirmative vote of a majority of all the votes cast “for” and “against” each director nominee. In contested elections, directors are elected by a plurality of the votes cast. See “Material Provisions of Maryland Law and of Our Charter and Bylaws—Our Board of Directors.”

Holders of shares of our common stock have no preference, conversion, exchange, sinking fund or redemption rights, and have no preemptive rights to subscribe for any securities of our company. Our charter provides that our stockholders generally have no appraisal rights unless our board of directors determines prospectively that appraisal rights will apply to one or more transactions in which holders of our common stock would otherwise be entitled to exercise appraisal rights. Subject to the provisions of our charter regarding the restrictions on ownership and transfer of our stock, holders of shares of our common stock will have equal dividend, liquidation and other rights.

Under the MGCL, a Maryland corporation generally cannot dissolve, amend its charter, merge, consolidate, convert into another type of entity, sell all or substantially all of its assets or engage in a statutory share exchange unless declared advisable by the board of directors and approved by the affirmative vote of stockholders entitled to cast at least two-thirds of all of the votes entitled to be cast on the matter unless a lesser percentage (but not

less than a majority of the votes entitled to be cast on the matter) is set forth in the corporation’s charter. Our charter provides for the approval of these matters by a majority of the votes entitled to be cast on the matter, except for the limited rights of holders of series B preferred stock described below under the heading “Description of Preferred Stock—8.375% Series B Preferred Stock” to approve certain amendments to our charter, and except that the approval of stockholders entitled to cast at least two-thirds of all of the votes entitled to be cast is required to remove a director elected by holders of our common stock or to amend the removal provisions of our charter or the vote required to amend such provisions. Holders of outstanding shares of series B preferred stock, voting together as a single class with the holders of all outstanding shares of any other similarly-affected class or series of parity preferred stock upon which like voting rights have been conferred, have the exclusive right to vote on any amendment to our charter on which holders of our series B preferred stock are entitled to vote and that would alter only the contract rights, as expressly set forth in our charter, of the series B preferred stock and such other class or series of parity preferred stock, and the holders of any other class or series of our stock, including our common stock, will not be entitled to vote on such an amendment. Maryland law also permits a corporation to transfer all or substantially all of its assets without the approval of its stockholders to an entity all of the equity interests of which are owned, directly or indirectly, by the corporation. Because our operating assets may be held by our operating partnership or its wholly owned subsidiaries, these subsidiaries may be able to merge or transfer all or substantially all of such assets without the approval of our stockholders.

Our charter authorizes our board of directors to reclassify any unissued shares of our common stock into other classes or series of stock, to establish the designation and number of shares of each such class or series and to set, subject to the rights of holders of our series B preferred stock and any other class or series of our stock, and the provisions of our charter regarding the restrictions on ownership and transfer of our stock, the preferences, conversion or other rights, voting powers, restrictions, limitations as to dividends or other distributions, qualifications or terms or conditions of redemption of each such class or series.

Power to Increase or Decrease Authorized Shares of Common Stock and Issue Additional Shares of Common Stock

We believe that the power of our board of directors to amend our charter to increase or decrease the aggregate number of authorized shares of common stock, to authorize us to issue additional authorized but unissued shares of our common stock and to classify or reclassify unissued shares of our common stock and thereafter to cause us to issue such classified or reclassified shares will provide us with increased flexibility in structuring possible future financings and acquisitions and in meeting other needs that might arise. Subject to the rights of holders of series B preferred stock to approve the classification or issuance of shares, or increase in the number of authorized shares, of a class or series of our stock ranking senior to the series B preferred stock, the additional classes or series of common stock, as well as the additional authorized shares of common stock, will be available for issuance without further action by our stockholders unless such action is required by applicable law or the rules of any stock exchange or automated quotation system on which our securities may be listed or traded. Although our board of directors does not currently intend to do so, it could authorize us to issue a class or series of stock that could, depending upon the terms of the particular class or series, delay, defer or prevent a transaction or a change of control of our company that might involve a premium price for our common stock or that our common stockholders otherwise believe to be in their best interests. See “Material Provisions of Maryland Law and of Our Charter and Bylaws—Anti-takeover Effect of Certain Provisions of Maryland Law and of Our Charter and Bylaws.”

This prospectus describes the general terms of our preferred stock. For a more detailed description of these securities, you should read the applicable provisions of the MGCL and our charter and bylaws. When we offer to sell a particular class or series of preferred stock, we will describe the specific terms of the series in a prospectus supplement. Accordingly, for a description of the terms of any class or series of preferred stock, you must refer to both the prospectus supplement relating to that class or series and the description of preferred stock in this prospectus. To the extent the information contained in the prospectus supplement differs from this summary description, you should rely on the information in the prospectus supplement.

Our charter provides that we may issue up to 10 million shares of preferred stock, $0.01 par value per share, or preferred stock, of which 5,800,000 shares are classified and designated as shares of series B preferred stock. Our charter authorizes our board of directors, with the approval of a majority of the entire board and without any action by our stockholders, to amend our charter to increase or decrease the aggregate number of shares of stock or, subject to the rights of holders of series B preferred stock to approve any increase in the number of shares of a class or series of stock ranking senior to our series B preferred stock, the number of shares of stock of any class or series that we have the authority to issue. As of January 12, 2015, 5,800,000 shares of our series B preferred stock are issued and outstanding.

Our charter authorizes our board of directors to classify any unissued shares of preferred stock and to reclassify any previously classified but unissued shares of preferred stock into one or more classes or series of stock. Prior to issuance of shares of each new class or series, our board of directors is required by the MGCL and our charter to set, subject to the rights of holders of our series B preferred stock and any other class or series of our stock, and the provisions of our charter regarding the restrictions on ownership and transfer of our stock, the preferences, conversion or other rights, voting powers, restrictions, limitations as to dividends or other distributions, qualifications or terms or conditions of redemption of each such class or series. As a result, our board of directors could authorize the issuance of shares of preferred stock that have priority over shares of our common stock with respect to dividends, distributions or rights upon liquidation or with other terms or conditions that could have the effect of delaying, deferring or preventing a transaction or a change of control of our company that might involve a premium price for our common stock or that our common stockholders otherwise believe to be in their best interests.

The specific terms of a particular class or series of preferred stock will be described in the prospectus supplement relating to that class or series, including a prospectus supplement providing that preferred stock may be issuable upon the exercise of warrants we issue. The description of preferred stock set forth below and the description of the terms of a particular class or series of preferred stock set forth in the applicable prospectus supplement do not purport to be complete and are qualified in their entirety by reference to the articles supplementary relating to that class or series.

Under Maryland law, stockholders generally are not personally liable for our debts or obligations solely as a result of their status as stockholders.

The preferences and other terms of each class or series of preferred stock will be fixed by the articles supplementary relating to such class or series. A prospectus supplement relating to each class or series will specify the terms of the class or series of preferred stock as follows:

Unless otherwise specified in the applicable prospectus supplement, the preferred stock will, with respect to dividend rights and rights upon liquidation, dissolution or winding up of our company, rank: (1) senior to all classes or series of our common stock, and to any other class or series of our stock expressly designated as ranking junior to the preferred stock; (2) on parity with any class or series of our stock expressly designated as ranking on parity with the preferred stock; and (3) junior to any other class or series of our stock expressly designated as ranking senior to the preferred stock.

The terms and conditions, if any, upon which any shares of any class or series of preferred stock are convertible into shares of our common stock or shares of any other class or series of our stock will be set forth in the applicable prospectus supplement relating thereto. Such terms will include the number of shares of our common stock or the number of shares of such other class or series of our stock into which the shares of preferred stock are convertible, the conversion price (or manner of calculation thereof), the conversion period, provisions as to whether conversion will be at the option of the holders of such class or series of preferred stock, the events requiring an adjustment of the conversion price and provisions affecting conversion in the event of the redemption of such class or series of preferred stock.

Power to Increase or Decrease Authorized Preferred Stock and Issue Additional Shares of Our Preferred Stock

We believe that the power of our board of directors to amend our charter to increase or decrease the aggregate number of authorized shares of preferred stock, to authorize us to issue additional authorized but unissued shares of our preferred stock in one or more classes or series and to classify or reclassify unissued

shares of our preferred stock and thereafter to cause us to issue such classified or reclassified shares will provide us with increased flexibility in structuring possible future financings and acquisitions and in meeting other needs that might arise. Subject to the rights of holders of series B preferred stock to approve the classification or issuance of shares, or increase in the number of authorized shares, of a class or series of our stock ranking senior to the series B preferred stock, the additional classes or series of preferred stock, as well as the additional authorized shares of preferred stock, will be available for issuance without further action by our stockholders unless such action is required by applicable law or the rules of any stock exchange or automated quotation system on which our securities may be listed or traded. Although our board of directors does not currently intend to do so, it could authorize us to issue a class or series of stock that could, depending upon the terms of the particular class or series, delay, defer or prevent a transaction or a change of control of our company that might involve a premium price for our common stock or that our common stockholders otherwise believe to be in their best interests. See “Material Provisions of Maryland Law and of Our Charter and Bylaws—Anti-takeover Effect of Certain Provisions of Maryland Law and of Our Charter and Bylaws.”

To assist us in complying with certain federal income tax requirements applicable to REITs, our charter contains certain restrictions relating to the ownership and transfer of our preferred stock. We expect that similar restrictions with respect to any class or series offered pursuant to this prospectus will be set forth in the articles supplementary for such class or series. The applicable prospectus supplement will specify any additional ownership limitation relating to such class or series. See “Restrictions on Ownership and Transfer.”

The transfer agent and registrar for our shares of preferred stock is Computershare Trust Company, N.A.

We currently have outstanding 5,800,000 shares of our 8.375% series B cumulative redeemable preferred stock, $0.01 par value per share, or series B preferred stock. Our series B preferred stock is listed on the NYSE under the symbol “HPP. PrB.” Dividends on outstanding shares of our series B preferred stock are cumulative from the date of original issue and are payable quarterly in arrears at the rate of 8.375% per annum of its $25.00 liquidation preference, or $2.09375 per annum per share.

If following a change of control of our company, either our series B preferred stock (or any preferred stock of the surviving entity that is issued in exchange for our series B preferred stock) or the common stock of the surviving entity, as applicable, is not listed on the NYSE or quoted on the NASDAQ Stock Market, or NASDAQ (or listed or quoted on a successor exchange or quotation system), dividends on outstanding shares of our series B preferred stock will accrue and be cumulative from, and including, the first date on which both the change of control occurred and either our series B preferred stock (or any preferred stock of the surviving entity that is issued in exchange for our series B preferred stock) or the common stock of the surviving entity, as applicable, is not so listed or quoted, at the increased rate of 12.375% per annum per share of the liquidation preference of our series B preferred stock (equivalent to $3.09375 per annum per share), for as long as either our series B preferred stock (or any preferred stock of the surviving entity that is issued in exchange for our series B preferred stock) or the common stock of the surviving entity, as applicable, is not so listed or quoted.

Except in instances relating to preservation of our qualification as a REIT or in connection with a change of control of our company, our series B preferred stock is not redeemable prior to December 10, 2015. On and after December 10, 2015, we may redeem our series B preferred stock in whole, at any time, or in part, from time to time, for cash at a redemption price of $25.00 per share, plus any accrued and unpaid dividends to, but not including, the date of redemption. If at any time following a change of control either our series B preferred stock (or any preferred stock of the surviving entity that is issued in exchange for our series B preferred stock) or the common stock of the surviving entity, as applicable, is not listed on the NYSE or quoted on NASDAQ (or listed

or quoted on a successor exchange or quotation system), we will have the option to redeem our series B preferred stock, in whole but not in part, within 90 days after the first date on which both the change of control has occurred and either our series B preferred stock (or any preferred stock of the surviving entity that is issued in exchange for our series B preferred stock) or the common stock of the surviving entity, as applicable, is not so listed or quoted, for cash at $25.00 per share, plus accrued and unpaid dividends, if any, to, but not including, the redemption date. Our series B preferred stock has no maturity date and will remain outstanding indefinitely unless redeemed by us, and it is not subject to any sinking fund or mandatory redemption and is not convertible into or exchangeable for any property or any other securities.

Upon any liquidation, dissolution or winding up of our company, holders of our series B preferred stock will have the right to receive $25.00 per share, plus an amount per share equal to all accumulated and unpaid dividends (whether or not earned or declared) to, but not including, the date of payment, before any payments or distributions are made to holders of our common stock or other junior securities. Holders of our series B preferred stock generally have no voting rights, except that, if we are in arrears on dividends on our series B preferred stock for six or more quarterly periods (whether or not consecutive), the holders of our series B preferred stock, voting together as a single class with the holders of all other classes and series of parity preferred stock upon which like voting rights have been conferred and are exercisable, will have the right to elect an additional two directors until all such dividends and dividends for the then current quarterly period on our series B preferred stock have been paid or declared and set aside for payment in full. In addition, the approval of two-thirds of the votes entitled to be cast by the holders of outstanding shares of our series B preferred stock, voting together as a single class with holders of all other similarly-affected classes and series of parity preferred stock upon which like voting rights have been conferred, is required to authorize, create or increase the authorized number of shares of any class or series of our stock having rights senior to our series B preferred stock with respect to the payment of dividends or amounts upon liquidation, dissolution or winding up or to amend our charter, whether by merger, consolidation or otherwise, to affect materially and adversely the voting powers, rights or preferences of our series B preferred stock, unless in connection with any such amendment, alteration or repeal, our series B preferred stock remains outstanding without the terms thereof being materially and adversely affected or is converted into or exchanged for preferred equity interests in the surviving entity having preferences, conversion and other rights, voting powers, restrictions, limitations as to dividends, qualifications and terms and conditions of redemption thereof that are substantially similar to those of our series B preferred stock (taking into account that we may not be the surviving entity).

We will set forth in the applicable prospectus supplement a description of any depositary shares, warrants, purchase contracts, rights or units issued by us that may be offered and sold pursuant to this prospectus.

The following summary with respect to restrictions on ownership and transfer of our stock sets forth certain general terms and provisions of our charter documents to which any prospectus supplement may relate. This summary does not purport to be complete and is subject to and qualified in its entirety by reference to our charter documents, as amended and supplemented from time to time, including any articles supplementary relating to any class or series of preferred stock offered and sold pursuant to this prospectus. Copies of our existing charter documents are filed with the Securities and Exchange Commission and are incorporated by reference as exhibits to the registration statement of which this prospectus is a part. Any amendment or supplement to our charter documents relating to an issuance of securities pursuant to this prospectus shall be filed with the Securities and Exchange Commission and shall be incorporated by reference as an exhibit to the applicable prospectus supplement. See “Where You Can Find More Information; Incorporation by reference.”

In order for us to qualify as a REIT under the Internal Revenue Code of 1986, as amended, or the Code, our stock must be beneficially owned by 100 or more persons during at least 335 days of a taxable year of 12 months (other than the first year for which an election to be a REIT has been made) or during a proportionate part of a shorter taxable year. Also, not more than 50% of the value of the outstanding shares of our stock (after taking into account certain options to acquire shares of stock) may be owned, directly, indirectly or through attribution, by five or fewer individuals (for this purpose, the term “individual” includes a supplemental unemployment compensation benefit plan, a private foundation or a portion of a trust permanently set aside or used exclusively for charitable purposes, but generally does not include a qualified pension plan or profit sharing trust) at any time during the last half of a taxable year (other than the first year for which an election to be a REIT has been made).

Our charter contains restrictions on the ownership and transfer of our common stock, series B preferred stock and capital stock that are intended to assist us in complying with these requirements and continuing to qualify as a REIT. The relevant sections of our charter provide that, subject to the exceptions described below, no person or entity may actually or beneficially own, or be deemed to own by virtue of the applicable constructive ownership provisions of the Code, more than 9.8% (in value or in number of shares, whichever is more restrictive) of the outstanding shares of our common stock or of our series B preferred stock, excluding any shares of common stock or series B preferred stock, respectively, that are not treated as outstanding for federal income tax purposes, or more than 9.8% (in value) of the aggregate of the outstanding shares of all classes and series of our capital stock. We refer to each of these restrictions as an “ownership limit” and collectively as the “ownership limits.” A person or entity that would have acquired actual, beneficial or constructive ownership of our stock but for the application of the ownership limits or any of the other restrictions on ownership and transfer of our stock discussed below is referred to as a “prohibited owner.”

The constructive ownership rules under the Code are complex and may cause stock owned actually or constructively by a group of related individuals and/or entities to be owned constructively by one individual or entity. As a result, the acquisition of less than 9.8% of our common stock or series B preferred stock (or the acquisition of an interest in an entity that owns, actually or constructively, our common stock or series B preferred stock) by an individual or entity could, nevertheless, cause that individual or entity, or another individual or entity, to own constructively in excess of 9.8% in value or in number of shares (whichever is more restrictive) of our outstanding common stock or series B preferred stock, as applicable, and thereby violate the applicable ownership limit.

Our board of directors may, in its sole and absolute discretion, prospectively or retroactively, waive one or more of the ownership limits with respect to a particular person if, among other limitations, it:

As a condition of our waiver, our board of directors may require an opinion of counsel or IRS ruling satisfactory to our board of directors in its sole and absolute discretion in order to determine or ensure our status as a REIT or such representations and/or undertakings as are reasonably necessary to make the determinations above. Our board of directors may impose such conditions or restrictions as it deems appropriate in connection with such an exception.

In connection with past offerings of our common stock, our board of directors granted the Farallon Funds and certain of their affiliates, which we refer to collectively as the Farallon excepted holders, exemptions from the ownership limits, subject to various conditions and limitations. During the time that such waivers have been or are effective, each Farallon excepted holder has been and will be subject to an increased ownership limit applicable to such holder, or the excepted holder limit, as applicable. As a condition to granting such excepted holder limits, the Farallon excepted holders made certain representations and covenants to us, including representations that, to their best knowledge, as a result of their ownership of shares of our common stock, no other person (other than our operating partnership) actually, beneficially, or constructively owns shares of our common stock in excess of the ownership limit and that, as of certain applicable dates, they did not actually or constructively own, or reasonably anticipate so owning, in excess of 9.9% (or, in certain cases, 5.45%) of the outstanding equity interests in any of the tenants that we have disclosed to the Farallon excepted holders in accordance with the terms of such waivers. Before we enter into or acquire a lease with a new tenant, we are obligated to disclose the new tenant to the Farallon excepted holders, and such holders have one business day to inform us as to whether they actually or constructively own, or reasonably anticipate so owning, more than 9.9% (or, in certain cases, 5.45%) of the equity interests in such tenant. If they do own such an interest, if we enter into a lease with that tenant, the rent from that tenant could fail to qualify under the REIT income tests. If this rent could prevent us from satisfying the REIT gross income tests, then our charter would require that the number of shares owned by the Farallon excepted holders in excess of the ownership limit be automatically transferred to a trust as described below. If this occurs, and the Farallon excepted holders gave us advance notice of their tenant ownership as described above, we would be obligated to indemnify the Farallon excepted holders for any damages they suffer as a result of the transfer of shares to the trust. In addition, even if the Farallon excepted holders do not own one of our tenants, they may later acquire over 9.9% (or, in certain cases, 5.45%) of the equity interests in that tenant without causing their exemption to be terminated, provided that (i) our annual income from that tenant and other tenants in which they own over a 9.9% (or, in certain cases, 5.45%) interest would not exceed 2% of our gross income and our annual income from certain tenants to which the lower 5.45% threshold applies would not exceed 2% of the gross income from one of our properties; and (ii) such ownership could not otherwise cause us to fail to qualify as a REIT. As a result, ownership of our tenants by the Farallon excepted holders may increase our nonqualifying income or prevent us from entering into certain leases with certain tenants. The representations and covenants made by the Farallon excepted holders in connection with the granting of the exemptions are intended to ensure that, despite granting such exemptions, we will continue to qualify as a REIT. The Farallon excepted holders must inform us if any of these representations becomes untrue or is violated, in which case they will lose their excepted holder limit. Subject to certain conditions, we may reduce the excepted holder limit (but not below the ownership limit) if the Farallon excepted holders actually, beneficially or constructively own fewer shares than the excepted holder limit for a specified period. Our board of directors has granted to our operating partnership an exemption from the ownership limits. In addition, our board of directors has granted to certain other holders an exemption from the ownership limits, based on certain representations and covenants made to us by each such holder regarding its ownership and disposition of shares of our common stock or shares of our series B preferred stock. Our board of directors has also agreed to grant to certain affiliates of The Blackstone Group L.P. exemptions from the ownership limits, subject to various conditions and limitations substantially similar to those described above. We believe that these exemptions will not jeopardize our status as a REIT for federal income tax purposes.

In connection with a waiver of an ownership limit or at any other time, our board of directors may increase or decrease one or more of the ownership limits, except that a decreased ownership limit will not be effective for any person whose actual, beneficial or constructive ownership of our stock exceeds the decreased ownership limit at the time of the decrease until the person’s actual, beneficial or constructive ownership of our stock equals or falls below the decreased ownership limit, although any further acquisition of our stock will violate the decreased ownership limit. Our board of directors may not increase or decrease any ownership limit if the new ownership limit would allow five or fewer persons to actually or beneficially own more than 49% in value of our outstanding stock or could cause us to be “closely held” under Section 856(h) of the Code (without regard to whether the ownership interest is held during the last half of a taxable year) or otherwise cause us to fail to qualify as a REIT.

Any person who acquires or attempts or intends to acquire actual, beneficial or constructive ownership of shares of our stock that will or may violate the ownership limits or any of the other restrictions on ownership and transfer of our stock described above must give written notice immediately to us or, in the case of a proposed or attempted transaction, provide us at least 15 days prior notice, and provide us with such other information as we may request in order to determine the effect of such transfer on our status as a REIT.

The ownership limits and other restrictions on ownership and transfer of our stock described above will not apply if our board of directors determines that it is no longer in our best interest to attempt to qualify, or to continue to qualify, as a REIT or that compliance with one or more of the restrictions or limitations on ownership and transfer of our stock is no longer required in order for us to qualify as a REIT.

Pursuant to our charter, if any purported transfer of our stock or any other event would otherwise result in any person violating the ownership limits or such other limit established by our board of directors, or could result in us being “closely held” within the meaning of Section 856(h) of the Code (without regard to whether the ownership interest is held during the last half of a taxable year) or otherwise failing to qualify as a REIT, then the number of shares causing the violation (rounded up to the nearest whole share) will be automatically transferred to, and held by, a trust for the exclusive benefit of one or more charitable organizations selected by us. The prohibited owner will have no rights in shares of our stock held by the trustee. The automatic transfer will be effective as of the close of business on the business day prior to the date of the violative transfer or other event that results in the transfer to the trust. Any dividend or other distribution paid to the prohibited owner, prior to our discovery that the shares had been automatically transferred to a trust as described above, must be repaid to the trustee upon demand. If the transfer to the trust as described above is not automatically effective, for any reason, to prevent violation of the applicable ownership limit or our being “closely held” (without regard to whether the ownership interest is held during the last half of a taxable year) or otherwise failing to qualify as a REIT, then the transfer of the number of shares that otherwise would cause any person to violate the above restrictions will be void. If any transfer of our stock would result in shares of our stock being beneficially owned by fewer than 100 persons (determined without reference to any rules of attribution), then any such purported transfer will be void and of no force or effect and the intended transferee will acquire no rights in the shares.

Shares of our stock transferred to the trustee are deemed offered for sale to us, or our designee, at a price per share equal to the lesser of (1) the price per share paid by the prohibited owner for the shares (or, if the prohibited owner did not give value in connection with the transfer or other event that resulted in the transfer to the trust

(e.g., a gift, devise or other such transaction), the last sales price reported on the NYSE on the day of the transfer or other event that resulted in the transfer of such shares to the trust) and (2) the last sale price reported on the NYSE on the date we, or our designee, accepts such offer. We must reduce the amount payable to the prohibited owner by the amount of dividends and distributions paid to the prohibited owner and owed by the prohibited owner to the trustee. We will pay the amount of such reduction to the trustee for the benefit of the charitable beneficiary. We have the right to accept such offer until the trustee has sold the shares of our stock held in the trust. Upon a sale to us, the interest of the charitable beneficiary in the shares sold terminates and the trustee must distribute the net proceeds of the sale to the prohibited owner and any dividends or other distributions held by the trustee with respect to such stock must be paid to the charitable beneficiary.

If we do not buy the shares, the trustee must, within 20 days of receiving notice from us of the transfer of shares to the trust, sell the shares to a person or persons, designated by the trustee, who could own the shares without violating the ownership limits or other restrictions on ownership and transfer of our stock. Upon such sale, the trustee must distribute to the prohibited owner an amount equal to the lesser of (1) the price paid by the prohibited owner for the shares (or, if the prohibited owner did not give value in connection with the transfer or other event that resulted in the transfer to the trust (e.g., a gift, devise or other such transaction), the last sales price reported on the NYSE on the day of the event that resulted in the transfer of such shares to the trust) and (2) the sales proceeds (net of commissions and other expenses of sale) received by the trustee for the shares. The trustee must reduce the amount payable to the prohibited owner by the amount of dividends and other distributions paid to the prohibited owner and owed by the prohibited owner to the trustee. Any net sales proceeds in excess of the amount payable to the prohibited owner will be immediately paid to the charitable beneficiary, together with any dividends or other distributions thereon. In addition, if, prior to discovery by us that shares of our stock have been transferred to the trustee, such shares of stock are sold by a prohibited owner, then such shares shall be deemed to have been sold on behalf of the trust and, to the extent that the prohibited owner received an amount for or in respect of such shares that exceeds the amount that such prohibited owner was entitled to receive, such excess amount must be paid to the trustee upon demand.

The trustee will be designated by us and will be unaffiliated with us and with any prohibited owner. Prior to the sale of any shares by the trust, the trustee will receive, in trust for the charitable beneficiary, all dividends and other distributions paid by us with respect to such shares, and may exercise all voting rights with respect to such shares for the exclusive benefit of the charitable beneficiary.

Subject to Maryland law, effective as of the date that the shares have been transferred to the trust, the trustee will have the authority, at the trustee’s sole discretion:

However, if we have already taken irreversible corporate action, then the trustee may not rescind and recast the vote.

If our board of directors or a committee thereof determines in good faith that a proposed transfer or other event has taken place that violates the restrictions on ownership and transfer of our stock set forth in our charter, our board of directors or such committee may take such action as it deems advisable in its sole discretion to refuse to give effect to or to prevent such transfer, including, but not limited to, causing the company to redeem shares of stock, refusing to give effect to the transfer on our books or instituting proceedings to enjoin the transfer.

Every owner of 5% or more (or such lower percentage as required by the Code or the Treasury Regulations promulgated thereunder) of the outstanding shares of our stock, within 30 days after the end of each taxable year, must give written notice to us stating the name and address of such owner, the number of shares of each class and

series of our stock that the owner beneficially owns and a description of the manner in which the shares are held. Each such owner also must provide us with any additional information that we request in order to determine the effect, if any, of the person’s actual or beneficial ownership on our status as a REIT and to ensure compliance with the ownership limits. In addition, any person that is an actual, beneficial or constructive owner of shares of our stock and any person (including the stockholder of record) who is holding shares of our stock for an actual, beneficial or constructive owner must, on request, disclose to us such information as we may request in good faith in order to determine our status as a REIT and comply with requirements of any taxing authority or governmental authority or determine such compliance.

Any certificates representing shares of our stock will bear a legend referring to the restrictions on ownership and transfer of our stock described above.

These restrictions on ownership and transfer could delay, defer or prevent a transaction or a change of control of our company that might involve a premium price for our stock that our stockholders otherwise believe to be in their best interest.

We have summarized the material terms and provisions of the Second Amended and Restated Agreement of Limited Partnership of Hudson Pacific Properties, L.P., which we refer to as the “partnership agreement.” This summary is not complete. For more detail, you should refer to the partnership agreement itself, a copy of which is filed with the Securities and Exchange Commission as an exhibit to the registration statement of which this prospectus is part. For purposes of this section, references to “we,” “our,” “us,” “our company” and the “general partner” refer to Hudson Pacific Properties, Inc. in our capacity as the general partner of our operating partnership.

All of our assets are held by, and substantially all of our operations are conducted through, our operating partnership, either directly or through subsidiaries. We are the general partner of the operating partnership, and, as of January 12, 2015, we own 96.5% of the outstanding common units in the operating partnership.

Certain persons who contributed interests in properties and/or other assets pursuant to the formation transactions related to our initial public offering received common units of partnership interest in our operating partnership or 6.25% Series A Cumulative Redeemable Partnership Units of partnership interest in our operating partnership, which we refer to as common units and series A preferred units, respectively. Holders of common units are generally entitled to share in cash distributions from, and in the profits and losses of, the operating partnership in proportion to their respective percentage interests of common units if and to the extent authorized by us and subject to the preferential rights of holders of outstanding preferred units, including series A preferred units and 8.375% Series B Cumulative Redeemable Preferred Units of partnership interest in our operating partnership, which we refer to as series B preferred units. Series A preferred units rank senior to any other partnership interest and holders of series A units are entitled to receive preferential cash distributions, a liquidation preference in the event of any voluntary or involuntary liquidation, dissolution or winding up of the affairs of the operating partnership (but only to the extent consistent with a liquidation in accordance with positive capital account balances), as well as certain conversion and redemption rights as described below in “—Material Terms of Our Series A Preferred Units.” Series B preferred units rank junior to the series A preferred units and senior to the common units and, subject to the rights of holders of series A preferred units, holders of series B preferred units are entitled to receive preferential cash distributions and a liquidation preference in the event of any voluntary or involuntary liquidation, dissolution or winding up of the affairs of the operating partnership that are substantially similar to those of the series B preferred stock (but, in the case of distributions upon the liquidation, dissolution or winding up of the affairs of the operating partnership, only to the extent consistent with a liquidation in accordance with positive capital account balances). Series B preferred units are also subject to redemption by the operating partnership in connection with our reacquisition of shares of series B preferred stock. See “Description of Preferred Stock—8.375% Series B Preferred Stock.” The units in the operating partnership are not listed on any exchange or quoted on any national market system.

Provisions in the partnership agreement could discourage third parties from making proposals involving an unsolicited acquisition of us or change of our control, although some stockholders might consider such proposals, if made, desirable. These provisions also make it more difficult for third parties to alter the management structure of the operating partnership without the concurrence of our board of directors. These provisions include, among others:

The purpose of the operating partnership includes the conduct of any business, enterprise or activity permitted by or under the Maryland Revised Uniform Limited Partnership Act. The operating partnership may enter into partnerships, joint ventures or similar arrangements and may own interests in any other entity. However, the operating partnership may not, without our consent, take, or refrain from taking, any action that, in our judgment, in our sole and absolute discretion:

In general, our board of directors manages the business and affairs of the operating partnership by directing our business and affairs, in our capacity as the general partner of the operating partnership.

Except as otherwise expressly provided in the partnership agreement, all management powers over the business and affairs of the operating partnership are exclusively vested in us, in our capacity as the general partner of the operating partnership. The general partner may not be removed by the partners with or without cause, except with the general partner’s consent. Except in connection with certain transactions involving the general partner discussed in “—Restrictions on Mergers, Sales, Transfers and Other Significant Transactions of the General Partner” and “—Material Terms of Series A Preferred Units—Voting and Consent Rights,” the general partner may authorize the operating partnership to dispose of any, all or substantially all of the assets (including the goodwill) of the operating partnership or merge, consolidate, reorganize or otherwise combine with or into another entity. With limited exceptions, the general partner is authorized to execute, deliver and perform agreements and transactions on behalf of the operating partnership without any further act, approval or vote of the limited partners.

The general partner may not take any action in contravention of the partnership agreement. The general partner may not, without the prior consent of a majority in interest of the partners (including us), undertake any actions on behalf of the operating partnership, or enter into any transaction, that would have the effect of amending, modifying or terminating the partnership agreement, except as provided in the partnership agreement. For a description of the provisions of the partnership agreement permitting the general partner to amend the partnership agreement without the consent of the limited partners see “—Amendment of the Partnership Agreement—Amendment by the General Partner without the Consent of the Limited Partners.” The general partner may not, without the prior consent of a majority in interest of the limited partners holding common units (excluding us and any limited partner a majority of whose equity is owned, directly or indirectly, by us), transfer all or any portion of its interest in the operating partnership, withdraw as the general partner of the operating partnership or admit into the operating partnership any successor general partners, subject to the exceptions discussed in “—Transfers and Withdrawals—Restrictions on Transfers by General Partner.”

In addition, the general partner may not amend the partnership agreement or take any action on behalf of the operating partnership, without the prior consent of each partner adversely affected by such amendment or action, if such amendment or action would:

Subject to the rights of limited partners holding series A preferred units, the general partner may cause the operating partnership to issue additional units from time to time, on terms and conditions and for such capital contributions as may be established by the general partner in its sole and absolute discretion. The net capital contribution need not be equal for all limited partners. No person may be admitted as an additional limited partner without the general partner’s consent, which consent may be given or withheld in its sole and absolute discretion.

Subject to the rights of the limited partners holding series A preferred units, any additional units may be issued in one or more classes, or one or more series of any of such classes, with such designations, preferences, conversion or other rights, voting powers or rights, restrictions, limitations as to distributions, qualifications or terms or conditions of redemption (including, without limitation, terms that may be senior or otherwise entitled to preference over existing units) as the general partner shall determine, in its sole and absolute discretion without the approval of any limited partner or any other person.

We may not conduct any business other than in connection with the ownership, acquisition and disposition of partnership interests, the management of the business of the operating partnership, our operation as a reporting company with a class or classes of securities registered under the Exchange Act, our operations as a REIT, the offering, sale, syndication, private placement or public offering of stock, bonds, securities or other interests related to the partnership or its assets or activities or our activities in our capacity as general partner, financing or refinancing of any type related to the operating partnership or its assets or activities, and such activities as are incidental to those activities discussed above. We may, however, in our sole and absolute discretion, from time to time hold or acquire assets in our own name or otherwise other than through the operating partnership so long as we take commercially reasonable measures to ensure that the economic benefits and burdens of such property are otherwise vested in the operating partnership.

We are required to cause the operating partnership to distribute quarterly, or on a more or less frequent basis as we may determine, all, or such portion as we may in our sole and absolute discretion determine, of the available cash (as such term is defined in the partnership agreement) generated by the operating partnership during such quarter to us and the limited partners:

We, as general partner of the operating partnership, are ultimately liable for all general recourse obligations of the operating partnership to the extent not paid by the operating partnership. We are not liable for the nonrecourse obligations of the operating partnership.

The partnership agreement generally provides that we, as general partner, and any of our respective directors or officers will incur no liability to the operating partnership, or any limited partner or assignee, for losses sustained or liabilities incurred or benefits not derived as a result of errors in judgment, mistakes of fact or law or any acts or omissions if we or such officer or director acted in good faith. The partnership agreement also provides that we will not be liable to the operating partnership or any partner for monetary damages for losses sustained, liabilities incurred or benefits not derived by the operating partnership or any limited partner, except for liability for our intentional harm or gross negligence. In addition, we, as general partner, are not responsible to the partnership for any misconduct or negligence on the part of our employees or agents, provided we appointed such employees or agents in good faith. We, as general partner, may consult with legal counsel, accountants, appraisers, management consultants, investment bankers and other consultants and advisors, and any action we take or omit to take in reliance upon the opinion of such persons, as to matters which we, as general partner, reasonably believe to be within their professional or expert competence, will be conclusively presumed to have been done or omitted in good faith and in accordance with such opinion.

The partnership agreement also provides for the indemnification of us, as general partner, and our directors, officers and employees, officers and employees of the operating partnership and such other persons as we, as general partner, may from time to time designate from and against any and all losses, claims, damages, liabilities, joint or several, expenses, judgments, fines, settlements and other amounts arising from any and all claims, demands, actions, suits or proceedings that relate to the operations of the operating partnership, provided that such person will not be indemnified for (i) any act or omission of such person that was material to the matter giving rise to the action and either was committed in bad faith or was the result of active and deliberate dishonesty, (ii) in the case of any criminal proceeding, any act or omission that such person had reason to believe was unlawful, or (iii) any transaction for which such person actually received an improper personal benefit in money, property or services or otherwise, in violation or breach of any provision of the partnership agreement. The operating partnership must also pay or reimburse the reasonable expenses of any such person upon its receipt of a written affirmation of the person’s good faith belief that the standard of conduct necessary for indemnification has been met and a written undertaking to repay any amounts paid or advanced if it is ultimately

determined that the person did not meet the standard of conduct for indemnification. The operating partnership will not indemnify or advance funds to any person with respect to any action initiated by the person seeking indemnification (other than an action to enforce such person’s right to indemnification under the partnership agreement) without our approval or if the person is found to be liable to the operating partnership on any portion of any claim in the action.

The partnership agreement also provides for the indemnification of each of the limited partners of our operating partnership, their affiliates and each of their respective directors, officers, stockholders and any other individual acting on its or their behalf, from and against any costs incurred by such person resulting from any litigation or other proceeding in which any limited partner is named as a defendant or any claim threatened or asserted against any limited partner that relates to the operations of the operating partnership or any obligation assumed by the operating partnership, unless such costs are the result of intentional harm or gross negligence on the part of, or a breach of partnership agreement by, such limited partner.

Under the partnership agreement, the general partner generally has the authority to cause the operating partnership to sell all or substantially all of the assets of the operating partnership or to merge, consolidate or otherwise combine its assets with another entity, without the consent or approval of any limited partner, subject to certain limitations described below. However, in connection with the acquisition of properties from persons to whom the general partner issued units as part of the purchase price, in order to preserve such persons’ tax deferral, the general partner may contractually agree, in general, not to sell or otherwise transfer the properties for a specified period of time, or in some instances, not to sell or otherwise transfer the properties without compensating the sellers of the properties for their loss of the tax deferral.

After 14 months of becoming a holder of common units, each limited partner and some assignees have the right, subject to the terms and conditions set forth in the partnership agreement, to require the operating partnership to redeem all or a portion of the common units held by such party in exchange for a cash amount per common unit equal to the value of one share of our common stock, as determined in accordance with, and subject to adjustment as provided in, the partnership agreement. The operating partnership’s obligation to effect a redemption, however, will not arise or be binding against the operating partnership unless and until we, as general partner, decline or fail to exercise our prior and independent right to acquire such common units in exchange for common stock.

On or before the close of business on the fifth business day after a limited partner gives us a notice of redemption with respect to common units, we may, in our sole and absolute discretion but subject to the restrictions on ownership and transfer of our stock discussed in “Restrictions on Ownership and Transfer,” acquire some or all of the tendered common units from the tendering party in exchange for shares of common stock, based on an exchange ratio of one share of common stock for each common unit, subject to adjustment as provided in the partnership agreement. The partnership agreement does not obligate us to register, qualify or list any common stock issued in exchange for common units with the Securities and Exchange Commission, with any state securities commissioner, department or agency, or with any stock exchange. Common stock issued in exchange for common units pursuant to the partnership agreement may contain legends regarding restrictions under the Securities Act and applicable state securities laws as we in good faith determine to be necessary or advisable in order to ensure compliance with securities laws.

Our operating partnership is required to redeem series B preferred units from us in connection with any redemption by us of shares of series B preferred stock. See “Description of Preferred Stock—8.375% Series B Preferred Stock.”

The partnership agreement also provides redemption rights with respect to our series A preferred units as described below in “—Material Terms of Our Series A Preferred Units.”

The partnership agreement restricts the transferability of units. Any transfer or purported transfer of a unit not made in accordance with the partnership agreement will be void.

Until the expiration of 14 months from the date on which a limited partner first acquired units, such limited partner generally may not, without our consent, directly or indirectly transfer all or any portion of its units to any transferee, except for certain permitted transfers to certain affiliates, family members and charities, transfers by a person who was a limited partner upon the completion of our initial public offering to its shareholders, members, partners or beneficiaries and certain pledges of units to lending institutions in connection with bona fide loans.

In addition, except in the case of permitted transfers, we have a right of first refusal with respect to any proposed transfers by other limited partners, exercisable within ten business days of notice of the transfer and a description of the proposed consideration to be paid for the operating partnership units.

We, as general partner, may not transfer any of our units or other partnership interest, whether by sale, disposition, statutory merger or consolidation, liquidation or otherwise, unless:

We may not voluntarily withdraw as a general partner of the operating partnership without the consent of a majority in interest of the limited partners holding common units (excluding us and any limited partner 50% or more of whose equity is owned, directly or indirectly, by us) other than upon the transfer of our entire interest in the operating partnership and the admission of our successor as a general partner of the operating partnership. A limited partner of the operating partnership may withdraw from the operating partnership only as a result of a transfer of the limited partner’s entire interest in the operating partnership in accordance with the partnership agreement and the admission of the limited partner’s successor as a limited partner of the operating partnership or as a result of the redemption or acquisition by us of the limited partner’s entire interest in the operating partnership.

Restrictions on Mergers, Sales, Transfers and Other Significant Transactions of the General Partner

We may not merge, consolidate or otherwise combine our assets with another entity, or sell all or substantially all of our assets not in the ordinary course of our business, or reclassify, recapitalize or change the terms of our outstanding common equity interests (other than in connection with a stock split, reverse stock split,

stock dividend, change in par value, increase in authorized shares, designation or issuance of new classes of equity securities or any event that does not require the approval of our stockholders), unless:

The following is a discussion of certain of the rights, privileges and preferences of the series A preferred units.

In the event of any voluntary or involuntary liquidation, dissolution or winding up of the affairs of the operating partnership, holders of series A preferred units will be entitled to receive and be paid in cash an amount equal to $25.00 per preferred unit plus any accrued and unpaid distributions before any distribution or payment may be made with respect to any other series or class of partnership interest ranking junior to the series A preferred units (but only to the extent consistent with a liquidation in accordance with positive capital account balances).

Holders of series A preferred units are entitled to receive, when, as and if declared by the operating partnership, out of available cash, cumulative preferential cash distributions in an amount equal to 6.25% per annum of the $25.00 liquidation preference per unit from the date of issuance of such unit, payable quarterly in arrears on or before the last calendar day of March, June, September and December of each year. Distributions that are due but unpaid will accumulate and compound quarterly. If any such preferential distribution payments for any past quarterly period are in arrears, no distributions may be authorized or paid on any other series or class of partnership interest ranking junior to the series A preferred units, nor shall any other series or class of partnership interests ranking junior to the series A preferred units be redeemed, purchased or acquired by the operating partnership or us, except for:

Beginning on June 29, 2013, each limited partner holding series A preferred units and certain assignees has had the right, subject to the terms and conditions set forth in the partnership agreement, to require the operating partnership to redeem all or a portion of their series A preferred units in exchange for a cash redemption price equal to $25.00 per unit plus any accrued distributions that have not been paid on or prior to the redemption date. The operating partnership’s obligation to effect a redemption, however, will not arise or be binding against the operating partnership unless and until we, as general partner, decline or fail to exercise our prior and independent right to acquire such preferred units in exchange for shares of our common stock that are issued under an effective registration statement under the Securities Act.

Beginning on June 29, 2013, each limited partner holding series A preferred units and certain assignees has had the right, subject to the terms and conditions set forth in the partnership agreement, to convert all or any portion of its series A preferred units into a number of common units with a value equal to the aggregate redemption price of the series A preferred units tendered for conversion, the value of such common units to be based on the ten-day trailing average closing price of our common stock calculated as of the business day immediately prior to the date of redemption. Any such conversion of series A preferred units will be deemed to have been made at the close of business on the date that we, as general partner, receive notice of conversion.

In the event of a recapitalization, reclassification or change of outstanding common units (other than a subdivision or combination of outstanding common units), a merger, sale or other business combination of our operating partnership, a sale, conveyance or lease to another or entity of all or substantially all of the operating partnership’s property and assets (other than to one or more of our subsidiaries) or an exchange of substantially all of the outstanding common units for securities of another entity, in each case in which holders of common units are entitled to receive securities, other property or assets with respect to or in exchange for their common units, qualifying holders of series A preferred units will thereafter be entitled to convert their series A preferred units into the kind and amount of securities or other consideration that such holder would have owned or been entitled to receive upon such a business combination if such holder had converted its series A preferred units into common units immediately before the business combination.

Generally, the series A preferred units are entitled to limited voting rights and in most cases vote on an as-converted basis with the holders of common units on any matter on which all limited partners are entitled to vote. However, so long as any series A preferred units remain outstanding, the consent of the limited partners holding a majority in interest of series A preferred units other than any limited partner 50% or more of whose equity is owned, directly or indirectly, by us will be required to:

Without the approval of limited partners holding a majority in interest of the series A preferred units, we may not engage in a “fundamental change,” unless upon consummation of such a fundamental change transaction the partnership agreement or other organizational documents of any successor to the operating partnership will contain certain provisions requiring our operating partnership or such successor to:

In connection with any fundamental change transaction, the operating partnership has the right to redeem all or any portion of the then outstanding series A preferred units for cash per unit equal to the redemption price.

The following summary of certain provisions of Maryland law and our charter and bylaws does not purport to be complete and is subject to and qualified in its entirety by reference to Maryland law and our charter and bylaws, copies of which are filed as exhibits to the registration statement of which this prospectus is a part. See “Where You Can Find More Information; Incorporation by Reference.”

Our charter and bylaws provide that the number of directors of our company may be established, increased or decreased only by a majority of our entire board of directors but may not be fewer than the minimum number required under the MGCL nor, unless our bylaws are amended, more than 15.

At each annual meeting of our stockholders, our stockholders will elect each of our directors to serve until the next annual meeting of our stockholders and until his or her successor is duly elected and qualifies under the MGCL. Holders of shares of our common stock will have no right to cumulative voting in the election of directors. In uncontested elections, directors are elected by the affirmative vote of a majority of all the votes cast “for” and “against” each director nominee. In contested elections, directors are elected by a plurality of the votes cast. An election will be considered to be contested if our company’s secretary has received notice that a stockholder has nominated or proposes to nominate one or more persons for election as a director, which notice complies or purports to comply with the requirements for advance notice of stockholder nominations set forth in our bylaws, and the nomination or proposed nomination has not been withdrawn at least 14 days prior to the date that our company’s proxy statement with respect to the meeting at which such nomination or proposed nomination would be made is first released to stockholders and would thereby cause the number of nominees and proposed nominees to exceed the number of directors to be elected at the meeting, irrespective of whether such notice complies with the requirements for advance notice of stockholder nominations set forth in our bylaws or such nomination or proposed nomination is thereafter withdrawn by such stockholder.

Additionally, in the event that we are in arrears on dividends on our series B preferred stock for six or more quarterly periods, whether or not consecutive, holders of our series B preferred stock, voting together as a single class with all other classes and series of parity preferred stock upon which like voting rights have been conferred and are exercisable, will have the right to elect an additional two directors until all such dividends and dividends for the then current quarterly period on our series B preferred stock have been paid or declared and set aside for payment in full.

We have elected by a provision of our charter to be subject to a provision of Maryland law requiring that, except as otherwise provided in the terms of any class or series of our stock, vacancies on our board of directors may be filled only by the remaining directors and that any individual elected to fill a vacancy will serve for the remainder of the full term of the class of directors in which the vacancy occurred and until his or her successor is duly elected and qualifies. Our charter provides that holders of series B preferred stock and parity preferred stock may fill vacancies among the directors entitled to be elected by the holders of series B preferred stock and parity preferred stock.

Our charter provides that, subject to the rights of holders of one or more classes or series of preferred stock to elect or remove one or more directors, a director may be removed only for cause (as defined in our charter) and only by the affirmative vote of at least two-thirds of the votes entitled to be cast generally in the election of directors. This provision, when coupled with the exclusive power of our board of directors to fill vacant directorships (other than vacancies among any directors elected by holders of our series B preferred stock pursuant to their right to elect an additional two directors to our board in certain circumstances as described above), may preclude stockholders from removing incumbent directors and filling the vacancies created by such

removal with their own nominees. In addition, any director elected to our board by the holders of our series B preferred stock and any class or series of parity preferred stock in the circumstances described above may only be removed by a vote of the holders of a majority of the outstanding shares of series B preferred stock and all classes and series of such parity preferred stock.

Under the MGCL, certain “business combinations” (including a merger, consolidation, statutory share exchange or, in certain circumstances specified under the statute, an asset transfer or issuance or reclassification of equity securities) between a Maryland corporation and any interested stockholder, or an affiliate of such an interested stockholder, are prohibited for five years after the most recent date on which the interested stockholder becomes an interested stockholder. Maryland law defines an interested stockholder as:

A person is not an interested stockholder if the board of directors approved in advance the transaction by which the person otherwise would have become an interested stockholder. In approving a transaction, however, the board of directors may provide that its approval is subject to compliance, at or after the time of the approval, with any terms and conditions determined by it.

After such five-year period, any such business combination must be recommended by the board of directors of the corporation and approved by the affirmative vote of at least:

These supermajority approval requirements do not apply if, among other conditions, the corporation’s common stockholders receive a minimum price (as defined in the MGCL) for their shares and the consideration is received in cash or in the same form as previously paid by the interested stockholder for its shares.

These provisions of the MGCL do not apply, however, to business combinations that are approved or exempted by a corporation’s board of directors prior to the time that the interested stockholder becomes an interested stockholder. Pursuant to the statute, our board of directors has by resolution exempted from the business combination provisions of the MGCL, and, consequently, the five-year prohibition and the supermajority vote requirements will not apply to, business combinations between us and any interested stockholder that have been approved by our board, including a majority of our directors who are not affiliated with the interested stockholder, unless our board in the future alters or repeals this resolution. As a result, anyone who is or later becomes an interested stockholder may be able to enter into business combinations with us without compliance by our company with the five-year moratorium, supermajority vote requirements and the other provisions of the statute.

We cannot assure you that our board of directors will not opt to be subject to such business combination provisions in the future. However, an alteration or repeal of this resolution will not have any effect on any business combinations that have been consummated or upon any agreements existing at the time of such modification or repeal.

The MGCL provides that a holder of “control shares” of a Maryland corporation acquired in a “control share acquisition” has no voting rights with respect to such shares except to the extent approved by the affirmative vote of at least two-thirds of the votes entitled to be cast by stockholders entitled to exercise or direct the exercise of the voting power in the election of directors generally but excluding: (1) the person who has made or proposes to make the control share acquisition, (2) any officer of the corporation or (3) any employee of the corporation who is also a director of the corporation. “Control shares” are voting shares of stock that, if aggregated with all other such shares of stock previously acquired by the acquirer or in respect of which the acquirer is able to exercise or direct the exercise of voting power (except solely by virtue of a revocable proxy), would entitle the acquirer to exercise voting power in electing directors within one of the following ranges:

Control shares do not include shares that the acquiring person is then entitled to vote as a result of having previously obtained stockholder approval. A “control share acquisition” means the acquisition, directly or indirectly, of ownership of, or the power to direct the exercise of voting power with respect to, issued and outstanding control shares, subject to certain exceptions.

A person who has made or proposes to make a control share acquisition, upon satisfaction of certain conditions (including an undertaking to pay expenses and making an “acquiring person statement” as described in the MGCL), may compel the board of directors to call a special meeting of stockholders to be held within 50 days of demand to consider the voting rights of the control shares. If no request for a special meeting is made, the corporation may itself present the question at any stockholders meeting.

If voting rights of control shares are not approved at the meeting or if the acquiring person does not deliver an “acquiring person statement” as required by the statute, then, subject to certain conditions and limitations, the corporation may redeem any or all of the control shares (except those for which voting rights have previously been approved) for fair value determined, without regard to the absence of voting rights for the control shares, as of the date of the last control share acquisition by the acquirer or of any meeting of stockholders at which the voting rights of such shares are considered and not approved. If voting rights for control shares are approved at a stockholders meeting and the acquirer becomes entitled to vote a majority of the shares entitled to vote, all other stockholders may exercise appraisal rights. The fair value of the shares as determined for purposes of such appraisal rights may not be less than the highest price per share paid by the acquirer in the control share acquisition.

The control share acquisition statute does not apply (1) to shares acquired in a merger, consolidation or statutory share exchange if the corporation is a party to the transaction or (2) to acquisitions approved or exempted by the charter or bylaws of the corporation.

Our bylaws contain a provision exempting from the control share acquisition statute any and all control share acquisitions by any person of shares of our stock. Our board of directors may amend or eliminate this provision at any time in the future.

Subtitle 8 of Title 3 of the MGCL permits a Maryland corporation with a class of equity securities registered under the Exchange Act and at least three independent directors to elect to be subject, by provision in its charter or bylaws or a resolution of its board of directors and notwithstanding any contrary provision in the charter or bylaws, to any or all of the following five provisions:

We have elected by a provision in our charter to be subject to the provisions of Subtitle 8 relating to the filling of vacancies on our board of directors. Through provisions in our charter and bylaws unrelated to Subtitle 8, we already (1) require a two-thirds vote for the removal of any director elected by holders of our common stock from the board, which removal must be for cause, (2) vest in the board the exclusive power to fix the number of directorships, subject to limitations set forth in our charter and bylaws, and (3) require, unless called by the chairman of our board of directors, our president, our chief executive officer or our board of directors, the request of stockholders entitled to cast not less than a majority of all votes entitled to be cast on a matter at such meeting to call a special meeting to consider and vote on any matter that may properly be considered at a meeting of stockholders. We have not elected to create a classified board. In the future, our board of directors may elect, without stockholder approval, to create a classified board or adopt one or more of the other provisions of Subtitle 8.

Our charter generally may be amended only if such amendment is declared advisable by our board of directors and approved by the affirmative vote of stockholders entitled to cast a majority of the votes entitled to be cast on the matter, except that (i) the provisions of our charter relating to the removal of directors and the vote required to amend the removal provision may be amended only with the approval of stockholders entitled to cast at least two-thirds of all of the votes entitled to be cast on the matter and (ii) certain amendments to our charter, whether by merger, consolidation, transfer or conveyance of all or substantially all of our assets, or otherwise, that would materially and adversely affect the terms of our series B preferred stock must be approved by the holders of the outstanding shares of our series B preferred stock entitled to cast at least two-thirds of the votes entitled to be cast on the matter, voting together as a single class with holders of shares of any similarly-affected class or series of parity preferred stock upon which like voting rights have been conferred. Holders of outstanding shares of series B preferred stock, voting together as a single class with the holders of outstanding shares of any other similarly-affected class or series of parity preferred stock upon which like voting rights have been conferred, have the exclusive right to vote on any amendments to our charter on which holders of series B preferred stock are entitled to vote and that would alter only the contract rights, as expressly set forth in our charter, of the series B preferred stock and such other class(es) and series of parity preferred stock, and the holders of shares of any other class(es) or series of our stock, including our common stock, will not be entitled to vote on such an amendment. Our board of directors has the exclusive power to adopt, alter or repeal any provision of our bylaws or to make new bylaws.

Under our bylaws, annual meetings of stockholders will be held each year at a date and time determined by our board of directors. Special meetings of stockholders may be called only by our board of directors, the chairman of our board of directors, our president or our chief executive officer. Additionally, subject to the provisions of our bylaws, special meetings of the stockholders to act on any matter must be called by our secretary upon the written request of stockholders entitled to cast at least a majority of the votes entitled to be cast at such meeting on such matter who have requested the special meeting in accordance with the procedures set forth in, and provided the information and certifications required by, our bylaws. In addition, at any time that holders of our series B preferred stock and any other class or series of parity preferred stock upon which like voting rights have been conferred have the right to elect two directors, but such directors have not been elected, our secretary is required to call a special meeting for the purpose of electing the preferred stock directors upon the written request of the holders of record of 10% of the outstanding shares of series B preferred stock and such

parity preferred stock, if this request is received more than 90 days before the date fixed for our next annual meeting of our stockholders. Only matters set forth in the notice of the special meeting may be considered and acted upon at such a meeting.

The purpose of requiring stockholders to give advance notice of nominations and other proposals is to afford our board of directors the opportunity to consider the qualifications of the proposed nominees or the advisability of the other proposals and, to the extent considered necessary by our board of directors, to inform stockholders and make recommendations regarding the nominations or other proposals. Although our bylaws do not give our board of directors the power to disapprove timely stockholder nominations and proposals, our bylaws may have the effect of precluding a contest for the election of directors or proposals for other action if the proper procedures are not followed, and of discouraging or deterring a third party from conducting a solicitation of proxies to elect its own slate of directors to our board of directors or to approve its own proposal.

Anti-takeover Effect of Certain Provisions of Maryland Law and Our Charter and Bylaws

The supermajority vote required to remove directors, our election to be subject to the provision of Subtitle 8 generally vesting in our board of directors the exclusive power to fill vacancies on our board of directors, the limited rights of holders of series B preferred stock to vote on certain mergers or consolidations involving us or transfers of all or substantially all of our assets and the advance notice provisions of our bylaws could delay, defer or prevent a transaction or a change of control of our company that might involve a premium price for our common stock or that our common stockholders otherwise believe to be in their best interests. Likewise, if our board of directors were to elect to be subject to the provision of Subtitle 8 providing for a classified board or if the provision in our bylaws opting out of the control share acquisition provisions of the MGCL were amended or rescinded, these provisions of the MGCL could have similar anti-takeover effects.

Maryland law permits a Maryland corporation to include in its charter a provision limiting the liability of its directors and officers to the corporation and its stockholders for money damages except for liability resulting from actual receipt of an improper benefit or profit in money, property or services or active and deliberate dishonesty that is established by a final judgment and is material to the cause of action. Our charter contains such a provision that eliminates such liability to the maximum extent permitted by Maryland law.

The MGCL requires a Maryland corporation (unless its charter provides otherwise, which our charter does not) to indemnify a director or officer who has been successful, on the merits or otherwise, in the defense of any proceeding to which he or she is made or threatened to be made a party by reason of his or her service in that capacity. The MGCL permits a Maryland corporation to indemnify its present and former directors and officers, among others, against judgments, penalties, fines, settlements and reasonable expenses actually incurred by them in connection with any proceeding to which they may be made or are threatened to be made a party by reason of their service in those or other capacities unless it is established that:

However, under the MGCL, a Maryland corporation may not indemnify a director or officer for an adverse judgment in a suit by or on behalf of the corporation or if the director or officer was adjudged liable on the basis that personal benefit was improperly received, unless in either case a court orders indemnification and then only for expenses.

In addition, the MGCL permits a Maryland corporation to advance reasonable expenses to a director or officer upon the corporation’s receipt of:

Our charter authorizes us to obligate our company and our bylaws obligate us, to the fullest extent permitted by Maryland law in effect from time to time, to indemnify and to pay or reimburse reasonable expenses in advance of final disposition of a proceeding without requiring a preliminary determination of the individual’s ultimate entitlement to indemnification to:

Our charter and bylaws also permit us, with the approval of our board of directors, to indemnify and advance expenses to any person who served a predecessor of ours in any of the capacities described above and to any employee or agent of our company or a predecessor of our company.

The partnership agreement of our operating partnership also provides that we, as general partner, and our directors, officers and employees, officers and employees of our operating partnership and our designees are indemnified against any and all losses, claims, damages, liabilities (whether joint or several), expenses (including, without limitation, attorneys’ fees and other legal fees and expenses), judgments, fines, settlements and other amounts arising from any and all claims, demands, actions, suits or proceedings, civil, criminal, administrative or investigative, that relate to the operations of the operating partnership, except (1) if the act or omission of such person was material to the matter giving rise to the action and either was committed in bad faith or was the result of active and deliberate dishonesty, (2) for any transaction for which such person received an improper personal benefit in money, property or services or otherwise, in violation or breach of any provision of the partnership agreement, or (3) in the case of a criminal proceeding, if the person had reasonable cause to believe the act or omission was unlawful. The operating partnership must also pay or reimburse the reasonable expenses of any such person upon its receipt of a written affirmation of the person’s good faith belief that the standard of conduct necessary for indemnification has been met and a written undertaking to repay any amounts paid or advanced if it is ultimately determined that the person did not meet the standard of conduct for indemnification. The operating partnership will not indemnify or advance funds to any person with respect to any action initiated by the person seeking indemnification (other than an action to enforce such person’s right to indemnification under the partnership agreement) without our approval or if the person is found to be liable to the operating partnership on any portion of any claim in the action. See “Description of the Partnership Agreement of Hudson Pacific Properties, L.P.—Exculpation and Indemnification.”

Insofar as the foregoing provisions permit indemnification of directors, officers or persons controlling us for liability arising under the Securities Act, we have been informed that in the opinion of the Securities and Exchange Commission, this indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

We have entered into indemnification agreements with each of our executive officers and directors as described in “Management—Limitation of Liability and Indemnification.”

Our charter contains restrictions on the ownership and transfer of our stock that are intended to assist us in continuing to qualify as a REIT. Subject to certain exceptions, our charter provides that no person or entity may beneficially own, or be deemed to own by virtue of the applicable constructive ownership provisions of the Code, more than 9.8% (in value or in number of shares, whichever is more restrictive) of the outstanding shares of our common stock or of our series B preferred stock, or 9.8% (in value) of the aggregate of the outstanding shares of all classes and series of our capital stock. For more information regarding these and other restrictions on the ownership and transfer of our stock imposed by our charter and the remedies for a violation of such restrictions, see “Description of Common Stock—Restrictions on Ownership and Transfer,” and “Description of Preferred Stock—Restrictions on Ownership and Transfer” and “Restrictions on Ownership and Transfer.”

Our charter provides that our board of directors may revoke or otherwise terminate our REIT election, without approval of our stockholders, if it determines that it is no longer in our best interest to continue to be qualified as a REIT.

The following is a general summary of certain material U.S. federal income tax considerations regarding our company, the exercise of redemption rights with respect to the common units, and the acquisition, ownership or disposition of our capital stock. Supplemental U.S. federal income tax considerations relevant to the ownership of the securities offered by this prospectus may be provided in the prospectus supplement that relates to those securities. For purposes of this discussion, references to “we,” “our” and “us” mean only Hudson Pacific Properties, Inc., and do not include any of its subsidiaries, except as otherwise indicated. This summary is for general information only and is not tax advice. The information in this summary is based on:

in each case, as of the date of this prospectus. In addition, the administrative interpretations and practices of the IRS include its practices and policies as expressed in private letter rulings that are not binding on the IRS except with respect to the particular taxpayers who requested and received those rulings. Future legislation, Treasury Regulations, administrative interpretations and practices and/or court decisions may adversely affect the tax considerations contained in this discussion. Any such change could apply retroactively to transactions preceding the date of the change. We have not requested and do not intend to request a ruling from the IRS that we qualify as a REIT, and the statements in this prospectus are not binding on the IRS or any court. Thus, we can provide no assurance that the tax considerations contained in this discussion will not be challenged by the IRS or will be sustained by a court if challenged by the IRS. This summary does not discuss any state, local or non-U.S. tax consequences associated with the exercise of redemption rights with respect to the common units, the acquisition, ownership, or disposition of our capital stock or our election to be taxed as a REIT.

You are urged to consult your tax advisors regarding the tax consequences to you of:

If you are a holder of common units and you exercise your right to require our operating partnership to redeem all or part of your common units, and we elect to acquire some or all of your common units in exchange for our common stock, the exchange will be a taxable transaction. You generally will recognize gain in an amount equal to the value of the common stock received, plus the amount of liabilities of our operating partnership allocable to your common units being acquired, less your tax basis in those units. The recognition of any loss is subject to a number of limitations set forth in the Code. The character of any gain or loss as capital or ordinary, or any gain as recapture gain under Section 1250 of the Code, will depend on the nature of the assets of our operating partnership at the time of the exchange. The tax treatment of any redemption of your units by our operating partnership for cash may be similar, depending on your circumstances.

We elected to be taxed as a REIT under Sections 856 through 860 of the Code commencing with our taxable year ended December 31, 2010. We believe that we have been organized and have operated in a manner that has allowed us to qualify for taxation as a REIT under the Code commencing with our taxable year ended December 31, 2010, and we intend to continue to be organized and operate in this manner. However, qualification and taxation as a REIT depend upon our ability to meet the various qualification tests imposed under the Code, including through actual annual operating results, asset composition, distribution levels and diversity of stock ownership. Accordingly, no assurance can be given that we have been organized and have operated, or will continue to be organized and operate, in a manner so as to qualify or remain qualified as a REIT. See “—Failure to Qualify.”

The sections of the Code and the corresponding Treasury Regulations that relate to qualification and taxation as a REIT are highly technical and complex. The following discussion sets forth certain material aspects of the sections of the Code that govern the federal income tax treatment of a REIT and its stockholders. This summary is qualified in its entirety by the applicable Code provisions, Treasury Regulations promulgated under the Code, and administrative and judicial interpretations thereof.

Latham & Watkins LLP has acted as our tax counsel in connection with this prospectus and our election to be taxed as a REIT. Latham & Watkins LLP has rendered an opinion to us to the effect that, commencing with our taxable year ended December 31, 2010, we have been organized and have operated in conformity with the requirements for qualification and taxation as a REIT under the Code, and our proposed method of operation will enable us to continue to meet the requirements for qualification and taxation as a REIT under the Code. It must be emphasized that this opinion was based on various assumptions and representations as to factual matters, including representations made by us in a factual certificate provided by one of our officers. In addition, this opinion was based upon our factual representations set forth in this prospectus. Moreover, our qualification and taxation as a REIT depend upon our ability to meet the various qualification tests imposed under the Code, which are discussed below, including through actual annual operating results, asset composition, distribution levels and diversity of stock ownership, the results of which have not been and will not be reviewed by Latham & Watkins LLP. Accordingly, no assurance can be given that our actual results of operation for any particular taxable year will satisfy those requirements. Further, the anticipated federal income tax treatment described in this discussion may be changed, perhaps retroactively, by legislative, administrative or judicial action at any time. Latham & Watkins LLP has no obligation to update its opinion subsequent to the date of such opinion.

Provided we qualify for taxation as a REIT, we generally will not be required to pay federal corporate income taxes on our REIT taxable income that is currently distributed to our stockholders. This treatment substantially eliminates the “double taxation” that ordinarily results from investment in a C corporation. A C corporation is a corporation that generally is required to pay tax at the corporate level. Double taxation means taxation once at the corporate level when income is earned and once again at the stockholder level when the income is distributed. We will, however, be required to pay federal income tax as follows:

Requirements for Qualification as a REIT. The Code defines a REIT as a corporation, trust or association:

The Code provides that conditions (1) to (4), inclusive, must be met during the entire taxable year and that condition (5) must be met during at least 335 days of a taxable year of 12 months, or during a proportionate part of a taxable year of less than 12 months. Conditions (5) and (6) do not apply until after the first taxable year for which an election is made to be taxed as a REIT. For purposes of condition (6), the term “individual” includes a supplemental unemployment compensation benefit plan, a private foundation or a portion of a trust permanently set aside or used exclusively for charitable purposes, but generally does not include a qualified pension plan or profit sharing trust.

We believe that we have been organized and have operated in a manner that has allowed us, and will continue to allow us, to satisfy conditions (1) through (7) inclusive, during the relevant time periods. In addition, our charter provides for restrictions regarding ownership and transfer of our shares that are intended to assist us in continuing to satisfy the share ownership requirements described in (5) and (6) above. A description of the share ownership and transfer restrictions relating to our outstanding capital stock is contained in the discussion in this prospectus under the heading “Restrictions on Ownership and Transfer.” These restrictions, however, may not ensure that we will, in all cases, be able to satisfy the share ownership requirements described in conditions (5) and (6) above. If we fail to satisfy these share ownership requirements, except as provided in the next sentence, our status as a REIT will terminate. If, however, we comply with the rules contained in applicable Treasury Regulations that require us to ascertain the actual ownership of our shares and we do not know, or would not have known through the exercise of reasonable diligence, that we failed to meet the requirement described in condition (6) above, we will be treated as having met this requirement. See “—Failure to Qualify.”

In addition, we may not maintain our status as a REIT unless our taxable year is the calendar year. We have and will continue to have a calendar taxable year.

Ownership of Interests in Partnerships, Limited Liability Companies and Qualified REIT Subsidiaries. In the case of a REIT that is a partner in a partnership or a member in a limited liability company treated as a partnership for federal income tax purposes, Treasury Regulations provide that the REIT will be deemed to own its proportionate share of the assets of the partnership or limited liability company, as the case may be, based on its interest in partnership capital, subject to special rules relating to the 10% asset test described below. Also, the REIT will be deemed to be entitled to its proportionate share of the income of that entity. The assets and gross income of the partnership or limited liability company retain the same character in the hands of the REIT for purposes of Section 856 of the Code, including satisfying the gross income tests and the asset tests. Thus, our pro rata share of the assets and items of income of our operating partnership, including our operating partnership’s share of these items of any partnership or limited liability company treated as a partnership or disregarded entity for federal income tax purposes in which it owns an interest, is treated as our assets and items of income for purposes of applying the requirements described in this discussion, including the gross income and asset tests

described below. A brief summary of the rules governing the federal income taxation of partnerships and limited liability companies is set forth below in “—Tax Aspects of Our Operating Partnership, the Subsidiary Partnerships and the Limited Liability Companies.”

We have control of our operating partnership and the subsidiary partnerships and limited liability companies and intend to operate them in a manner consistent with the requirements for our qualification as a REIT. If we become a limited partner or non-managing member in any partnership or limited liability company and such entity takes or expects to take actions that could jeopardize our status as a REIT or require us to pay tax, we may be forced to dispose of our interest in such entity. In addition, it is possible that a partnership or limited liability company could take an action which could cause us to fail a gross income or asset test, and that we would not become aware of such action in time to dispose of our interest in the partnership or limited liability company or take other corrective action on a timely basis. In that case, we could fail to qualify as a REIT unless we were entitled to relief, as described below.

We may from time to time own and operate certain properties through subsidiaries that we intend to be treated as “qualified REIT subsidiaries” under the Code. A corporation will qualify as our qualified REIT subsidiary if we own 100% of the corporation’s outstanding stock and do not elect with the subsidiary to treat it as a “taxable REIT subsidiary,” as described below. A qualified REIT subsidiary is not treated as a separate corporation, and all assets, liabilities and items of income, gain, loss, deduction and credit of a qualified REIT subsidiary are treated as assets, liabilities and items of income, gain, loss, deduction and credit of the parent REIT for all purposes under the Code, including all REIT qualification tests. Thus, in applying the federal tax requirements described in this discussion, any qualified REIT subsidiaries we own are ignored, and all assets, liabilities and items of income, gain, loss, deduction and credit of such corporations are treated as our assets, liabilities and items of income, gain, loss, deduction and credit. A qualified REIT subsidiary is not subject to federal income tax, and our ownership of the stock of a qualified REIT subsidiary will not violate the restrictions on ownership of securities, as described below under “—Asset Tests.”

Ownership of Interests in Taxable REIT Subsidiaries. We currently own an interest in one taxable REIT subsidiary and may acquire securities in additional taxable REIT subsidiaries in the future. A taxable REIT subsidiary is a corporation other than a REIT in which a REIT directly or indirectly holds stock, and that has made a joint election with such REIT to be treated as a taxable REIT subsidiary. If a taxable REIT subsidiary owns more than 35% of the total voting power or value of the outstanding securities of another corporation, such other corporation will also be treated as a taxable REIT subsidiary. Other than some activities relating to lodging and health care facilities, a taxable REIT subsidiary may generally engage in any business, including the provision of customary or non-customary services to tenants of its parent REIT. A taxable REIT subsidiary is subject to federal income tax as a regular C corporation. In addition, a taxable REIT subsidiary may be prevented from deducting interest on debt funded directly or indirectly by its parent REIT if certain tests regarding the taxable REIT subsidiary’s debt to equity ratio and interest expense are not satisfied. A REIT’s ownership of securities of a taxable REIT subsidiary is not subject to the 5% or 10% asset test described below. See “—Asset Tests.”

Ownership of Interests in Subsidiary REITs. We own and may acquire direct or indirect interests in one or more Subsidiary REITs. A Subsidiary REIT is subject to the various REIT qualification requirements and other limitations described herein that are applicable to us. If a Subsidiary REIT were to fail to qualify as a REIT, then (i) that Subsidiary REIT would become subject to federal income tax, (ii) shares in such Subsidiary REIT would cease to be qualifying assets for purposes of the asset tests applicable to REITs, and (iii) it is possible that we would fail certain of the asset tests applicable to REITs, in which event we would fail to qualify as a REIT unless we could avail ourselves of certain relief provisions.

We must satisfy two gross income requirements annually to maintain our qualification as a REIT. First, in each taxable year we must derive directly or indirectly at least 75% of our gross income (excluding gross income

from prohibited transactions, certain hedging transactions, and certain foreign currency gains) from investments relating to real property or mortgages on real property, including “rents from real property”, dividends from other REITs and, in certain circumstances, interest, or certain types of temporary investments. Second, in each taxable year we must derive at least 95% of our gross income (excluding gross income from prohibited transactions, certain hedging transactions, and certain foreign currency gains) from the real property investments described above or dividends, interest and gain from the sale or disposition of stock or securities, or any combination of the foregoing. For these purposes, the term “interest” generally does not include any amount received or accrued, directly or indirectly, if the determination of all or some of the amount depends in any way on the income or profits of any person. However, an amount received or accrued generally will not be excluded from the term “interest” solely by reason of being based on a fixed percentage or percentages of receipts or sales.

Rents we receive from a tenant will qualify as “rents from real property” for the purpose of satisfying the gross income requirements for a REIT described above only if all of the following conditions are met:

We generally do not intend, and as a general partner of our operating partnership, do not intend to permit our operating partnership, to take actions we believe will cause us to fail to satisfy the rental conditions described above. However, we may intentionally fail to satisfy some of these conditions to the extent we determine, based on the advice of our tax counsel, that the failure will not jeopardize our tax status as a REIT. In addition, with respect to the limitation on the rental of personal property, we have not obtained appraisals of the real property and personal property leased to tenants. Accordingly, there can be no assurance that the IRS will not disagree with our determinations of value. Moreover, in connection with granting the excepted holder limits to the certain excepted holders, we have obtained and, in the future, may obtain representations from these entities in order to ensure that we generally will not be deemed to own an interest in any of our tenants, or in the event we are treated as owning such an interest as a result of granting such waiver, we will not derive nonqualifying rental income in excess of certain thresholds.

Some of our leases are in the form of licenses and have terms of less than 30 days (“short-term licenses”). The treatment of rents derived with respect to these short-term licenses for purposes of the gross income tests is not entirely clear. We believe that rents derived with respect to these short-term licenses should qualify as “rents from real property” for purposes of the gross income tests, although there can be no assurance that the IRS will not take a contrary position. If the payments we receive in connection with such short-term licenses do not qualify as “rents from real property,” such payments would not be treated as qualifying income for purposes of the gross income tests.

Income we receive that is attributable to the rental of parking spaces at the properties generally will constitute rents from real property for purposes of the gross income tests if certain services provided with respect to the parking spaces are performed by independent contractors from whom we derive no revenue, either directly or indirectly, or by a taxable REIT subsidiary, and certain other conditions are met. We believe that the income we receive that is attributable to parking spaces meets these tests and, accordingly, will constitute rents from real property for purposes of the gross income tests.

From time to time, we may enter into hedging transactions with respect to one or more of our assets or liabilities. Our hedging activities may include entering into interest rate swaps, caps, and floors, options to purchase these items, and futures and forward contracts. Income from a hedging transaction, including gain from the sale or disposition of such a transaction, that is clearly identified as a hedging transaction as specified in the Code will not constitute gross income and thus will be exempt from the 75% and 95% gross income tests. The term “hedging transaction,” as used above, generally means any transaction we enter into in the normal course of our business primarily to manage risk of (1) interest rate changes or fluctuations with respect to borrowings made or to be made by us to acquire or carry real estate assets, or (2) currency fluctuations with respect to an item of qualifying income under the 75% or 95% gross income test. To the extent that we do not properly identify such transactions as hedges or we hedge with other types of financial instruments, the income from those transactions is not likely to be treated as qualifying income for purposes of the gross income tests. We intend to structure any hedging transactions in a manner that does not jeopardize our status as a REIT.

To the extent our taxable REIT subsidiaries pay dividends, we generally will derive our allocable share of such dividend income through our interest in our operating partnership. Such dividend income will qualify under the 95%, but not the 75%, gross income test.

We will monitor the amount of the dividend and other income from our taxable REIT subsidiaries and will take actions intended to keep this income, and any other nonqualifying income, within the limitations of the gross income tests. Although we expect these actions will be sufficient to prevent a violation of the gross income tests, we cannot guarantee that such actions will in all cases prevent such a violation.

If we fail to satisfy one or both of the 75% or 95% gross income tests for any taxable year, we may nevertheless qualify as a REIT for the year if we are entitled to relief under certain provisions of the Code. We generally may make use of the relief provisions if:

It is not possible, however, to state whether in all circumstances we would be entitled to the benefit of these relief provisions. For example, if we fail to satisfy the gross income tests because nonqualifying income that we intentionally accrue or receive exceeds the limits on nonqualifying income, the IRS could conclude that our failure to satisfy the tests was not due to reasonable cause. If these relief provisions do not apply to a particular set of circumstances, we will not qualify as a REIT. As discussed above in “—Taxation of Our Company—General,” even if these relief provisions apply, and we retain our status as a REIT, a tax would be imposed with respect to our nonqualifying income. We may not always be able to comply with the gross income tests for REIT qualification despite periodic monitoring of our income.

Prohibited Transaction Income. Any gain that we realize on the sale of property held as inventory or otherwise held primarily for sale to customers in the ordinary course of business, including our share of any such gain realized by our operating partnership, either directly or through its subsidiary partnerships and limited liability companies, will be treated as income from a prohibited transaction that is subject to a 100% penalty tax, unless certain safe harbor exceptions apply. This prohibited transaction income may also adversely affect our ability to satisfy the gross income tests for qualification as a REIT. Under existing law, whether property is held as inventory or primarily for sale to customers in the ordinary course of a trade or business is a question of fact that depends on all the facts and circumstances surrounding the particular transaction. Our operating partnership intends to hold its properties for investment with a view to long-term appreciation, to engage in the business of acquiring, developing and owning its properties and to make occasional sales of the properties as are consistent with our operating partnership’s investment objectives. We do not intend to enter into any sales that are prohibited transactions. However, the IRS may successfully contend that some or all of the sales made by our operating partnership or its subsidiary partnerships or limited liability companies are prohibited transactions. We would be required to pay the 100% penalty tax on our allocable share of the gains resulting from any such sales.

Penalty Tax. Any redetermined rents, redetermined deductions or excess interest we generate will be subject to a 100% penalty tax. In general, redetermined rents are rents from real property that are overstated as a result of any services furnished to any of our tenants by a taxable REIT subsidiary of ours, and redetermined deductions and excess interest represent any amounts that are deducted by a taxable REIT subsidiary of ours for amounts paid to us that are in excess of the amounts that would have been deducted based on arm’s length negotiations. Rents we receive will not constitute redetermined rents if they qualify for certain safe harbor provisions contained in the Code.

Currently, certain wholly owned subsidiaries of our taxable REIT subsidiary (which is our services company) provide services to certain of our tenants and pay rent to us and, from time to time, we may enter into additional leases with our taxable REIT subsidiaries that also provide services to our tenants. We believe we have set, and we intend to set in the future, any fees paid to our taxable REIT subsidiaries for such services, and any rent payable to us by our taxable REIT subsidiaries, at arm’s length rates, although the amounts paid may not satisfy the safe-harbor provisions described above. These determinations are inherently factual, and the IRS has

broad discretion to assert that amounts paid between related parties should be reallocated to clearly reflect their respective incomes. If the IRS successfully made such an assertion, we would be required to pay a 100% penalty tax on the excess of an arm’s length fee for tenant services over the amount actually paid, or on the excess rents paid to us.

At the close of each calendar quarter of our taxable year, we must also satisfy certain tests relating to the nature and diversification of our assets. First, at least 75% of the value of our total assets must be represented by real estate assets, cash, cash items and U.S. government securities. For purposes of this test, the term “real estate assets” generally means real property (including interests in real property and interests in mortgages on real property) and shares (or transferable certificates of beneficial interest) in other REITs, as well as any stock or debt instrument attributable to the investment of the proceeds of a stock offering or a public offering of debt with a term of at least five years, but only for the one-year period beginning on the date the REIT receives such proceeds.

Second, not more than 25% of the value of our total assets may be represented by securities (including securities of taxable REIT subsidiaries), other than those securities includable in the 75% asset test.

Third, of the investments included in the 25% asset class, and except for investments in other REITs, our qualified REIT subsidiaries and taxable REIT subsidiaries, the value of any one issuer’s securities may not exceed 5% of the value of our total assets, and we may not own more than 10% of the total vote or value of the outstanding securities of any one issuer except, in the case of the 10% value test, securities satisfying the “straight debt” safe-harbor or securities issued by a partnership that itself would satisfy the 75% income test if it were a REIT. Certain types of securities we may own are disregarded as securities solely for purposes of the 10% value test, including, but not limited to, any loan to an individual or an estate, any obligation to pay rents from real property and any security issued by a REIT. In addition, solely for purposes of the 10% value test, the determination of our interest in the assets of a partnership or limited liability company in which we own an interest will be based on our proportionate interest in any securities issued by the partnership or limited liability company, excluding for this purpose certain securities described in the Code. From time to time we may own securities (including debt securities) of issuers that do not qualify as a REIT, a qualified REIT subsidiary or a taxable REIT subsidiary. We intend that our ownership of any such securities will be structured in a manner that allows us to comply with the asset tests described above.

Our operating partnership currently owns 100% of the securities of a corporation that has elected, together with us, to be treated as our taxable REIT subsidiary. So long as this corporation qualifies as our taxable REIT subsidiary, we will not be subject to the 5% asset test, the 10% voting securities limitation or the 10% value limitation with respect to our ownership of its securities. We may acquire securities in other taxable REIT subsidiaries in the future. We believe that the aggregate value of our taxable REIT subsidiary and our other securities (other than those securities which are qualifying assets for purposes of the 75% asset test) has not exceeded, and in the future will not exceed, 25% of the aggregate value of our gross assets.

No independent appraisals have been obtained to support these conclusions. In addition, there can be no assurance that the IRS will not disagree with our determinations of value.

The asset tests must be satisfied at the close of each calendar quarter of our taxable year in which we (directly or through our operating partnership) acquire securities in the applicable issuer, and also at the close of each calendar quarter in which we increase our ownership of securities of such issuer (including as a result of increasing our interest in our operating partnership). For example, our indirect ownership of securities of each issuer will increase as a result of our capital contributions to our operating partnership or as limited partners exercise their redemption/exchange rights. Accordingly, after initially meeting the asset tests at the close of any quarter, we will not lose our status as a REIT for failure to satisfy the asset tests at the end of a later quarter solely by reason of changes in asset values. If we fail to satisfy an asset test because we acquire securities or

other property during a quarter (including as a result of an increase in our interest in our operating partnership), we may cure this failure by disposing of sufficient nonqualifying assets within 30 days after the close of that quarter. We believe that we have maintained, and we intend to maintain, adequate records of the value of our assets to ensure compliance with the asset tests. If we fail to cure any noncompliance with the asset tests within the 30-day cure period, we would cease to qualify as a REIT unless we are eligible for certain relief provisions discussed below.

Certain relief provisions may be available to us if we discover a failure to satisfy the asset tests described above after the 30-day cure period. Under these provisions, we will be deemed to have met the 5% and 10% asset tests if the value of our nonqualifying assets (i) does not exceed the lesser of (a) 1% of the total value of our assets at the end of the applicable quarter or (b) $10,000,000, and (ii) we dispose of the nonqualifying assets or otherwise satisfy such tests within (a) six months after the last day of the quarter in which the failure to satisfy the asset tests is discovered or (b) the period of time prescribed by Treasury Regulations to be issued. For violations of any of the asset tests due to reasonable cause and not due to willful neglect and that are, in the case of the 5% and 10% asset tests, in excess of the de minimis exception described above, we may avoid disqualification as a REIT after the 30-day cure period by taking steps including (i) the disposition of sufficient nonqualifying assets, or the taking of other actions, which allow us to meet the asset tests within (a) six months after the last day of the quarter in which the failure to satisfy the asset tests is discovered or (b) the period of time prescribed by Treasury Regulations to be issued, (ii) paying a tax equal to the greater of (a) $50,000 or (b) the highest corporate tax rate multiplied by the net income generated by the nonqualifying assets, and (iii) disclosing certain information to the IRS.

Although we believe we have satisfied the asset tests described above and plan to take steps to ensure that we satisfy such tests for any quarter with respect to which retesting is to occur, there can be no assurance that we will always be successful, or will not require a reduction in our operating partnership’s overall interest in an issuer (including in a taxable REIT subsidiary). If we fail to cure any noncompliance with the asset tests in a timely manner, and the relief provisions described above are not available, we would cease to qualify as a REIT.

To maintain our qualification as a REIT, we are required to distribute dividends, other than capital gain dividends, to our stockholders in an amount at least equal to the sum of:

For these purposes, our “REIT taxable income” is computed without regard to the dividends paid deduction and our net capital gain. In addition, for purposes of this test, non-cash income means income attributable to leveled stepped rents, original issue discount on purchase money debt, cancellation of indebtedness, or a like-kind exchange that is later determined to be taxable.

In addition, our “REIT taxable income” will be reduced by any taxes we are required to pay on any gain we recognize from the disposition of any asset we acquired from a corporation that is or has been a C corporation in a transaction in which our basis in the asset is less than the fair market value of the asset, in each case determined as of the date on which we acquired the asset, within the ten-year period following our acquisition of such asset.

We generally must pay, or be treated as paying, the distributions described above in the taxable year to which they relate. At our election, a distribution will be treated as paid in a taxable year if it is declared before we timely file our tax return for such year and paid on or before the first regular dividend payment after such declaration, provided such payment is made during the 12-month period following the close of such year. These distributions are treated as received by our stockholders in the year in which paid. This is so even though these

distributions relate to the prior year for purposes of the 90% distribution requirement. In order to be taken into account for purposes of our distribution requirement, the amount distributed must not be preferential—i.e., every stockholder of the class of stock to which a distribution is made must be treated the same as every other stockholder of that class, and no class of stock may be treated other than according to its dividend rights as a class. To the extent that we do not distribute all of our net capital gain, or distribute at least 90%, but less than 100%, of our “REIT taxable income,” as adjusted, we will be required to pay tax on the undistributed amount at regular corporate tax rates. We believe that we have made, and we intend to continue to make, timely distributions sufficient to satisfy these annual distribution requirements and to minimize our corporate tax obligations. In this regard, the partnership agreement of our operating partnership authorizes us, as general partner of our operating partnership, to take such steps as may be necessary to cause our operating partnership to distribute to its partners an amount sufficient to permit us to meet these distribution requirements and to minimize our corporate tax obligation.

We expect that our REIT taxable income will be less than our cash flow because of depreciation and other non-cash charges included in computing REIT taxable income. Accordingly, we anticipate that we generally will have sufficient cash or liquid assets to enable us to satisfy the distribution requirements described above. However, from time to time, we may not have sufficient cash or other liquid assets to meet these distribution requirements due to timing differences between the actual receipt of income and actual payment of deductible expenses, and the inclusion of income and deduction of expenses in determining our taxable income. In addition, we may decide to retain our cash, rather than distribute it, in order to repay debt or for other reasons. If these timing differences occur, we may borrow funds to pay dividends or pay dividends in the form of taxable stock dividends in order to meet the distribution requirements, while preserving our cash.

Under some circumstances, we may be able to rectify an inadvertent failure to meet the 90% distribution requirement for a year by paying “deficiency dividends” to our stockholders in a later year, which may be included in our deduction for dividends paid for the earlier year. Thus, we may be able to avoid being taxed on amounts distributed as deficiency dividends, subject to the 4% excise tax described below. However, we will be required to pay interest to the IRS based upon the amount of any deduction claimed for deficiency dividends.

Furthermore, we will be required to pay a 4% excise tax to the extent we fail to distribute during each calendar year at least the sum of 85% of our ordinary income for such year, 95% of our capital gain net income for the year and any undistributed taxable income from prior periods. Any ordinary income and net capital gain on which this excise tax is imposed for any year is treated as an amount distributed during that year for purposes of calculating such tax.

For purposes of the 90% distribution requirement and excise tax described above, dividends declared during the last three months of the taxable year, payable to stockholders of record on a specified date during such period and paid during January of the following year, will be treated as paid by us and received by our stockholders on December 31 of the year in which they are declared.

We may dispose of properties in transactions intended to qualify as like-kind exchanges under the Code. Such like-kind exchanges are intended to result in the deferral of gain for federal income tax purposes. The failure of any such transaction to qualify as a like-kind exchange could require us to pay federal income tax, possibly including the 100% prohibited transaction tax, depending on the facts and circumstances surrounding the particular transaction.

If we discover a violation of a provision of the Code that would result in our failure to qualify as a REIT, certain specified cure provisions may be available to us. Except with respect to violations of the gross income tests and asset tests (for which the cure provisions are described above), and provided the violation is due to

reasonable cause and not due to willful neglect, these cure provisions generally impose a $50,000 penalty for each violation in lieu of a loss of REIT status. If we fail to satisfy the requirements for taxation as a REIT in any taxable year, and the relief provisions do not apply, we will be required to pay tax, including any applicable alternative minimum tax, on our taxable income at regular corporate rates. Distributions to stockholders in any year in which we fail to qualify as a REIT will not be deductible by us, and we will not be required to distribute any amounts to our stockholders. As a result, we anticipate that our failure to qualify as a REIT would reduce the cash available for distribution by us to our stockholders. In addition, if we fail to qualify as a REIT, all distributions to stockholders will be taxable as regular corporate dividends to the extent of our current and accumulated earnings and profits. In such event, corporate distributees may be eligible for the dividends-received deduction. In addition, non-corporate stockholders, including individuals, may be eligible for the preferential tax rates on qualified dividend income. Unless entitled to relief under specific statutory provisions, we would also be ineligible to elect to be treated as a REIT for the four taxable years following the year for which we lose our qualification. It is not possible to state whether in all circumstances we would be entitled to this statutory relief.

Tax Aspects of Our Operating Partnership, the Subsidiary Partnerships and the Limited Liability Companies

General. All of our investments are held indirectly through our operating partnership. In addition, our operating partnership holds certain of its investments indirectly through subsidiary partnerships and limited liability companies which we believe have been and will continue to be treated as partnerships or disregarded entities for federal income tax purposes. In general, entities that are treated as partnerships or disregarded entities for federal income tax purposes are “pass-through” entities which are not required to pay federal income tax. Rather, partners or members of such entities are allocated their shares of the items of income, gain, loss, deduction and credit of the partnership or limited liability company, and are potentially required to pay tax on this income, without regard to whether they receive a distribution from the partnership or limited liability company. We will include in our income our share of these partnership and limited liability company items for purposes of the various gross income tests, the computation of our REIT taxable income, and the REIT distribution requirements. Moreover, for purposes of the asset tests, we will include our pro rata share of assets held by our operating partnership, including its share of its subsidiary partnerships and limited liability companies, based on our capital interests in each such entity. See “—Taxation of Our Company.”

Entity Classification. Our interests in our operating partnership and the subsidiary partnerships and limited liability companies involve special tax considerations, including the possibility that the IRS might challenge the status of these entities as partnerships (or disregarded entities). For example, an entity that would otherwise be treated as a partnership for federal income tax purposes may nonetheless be taxable as a corporation if it is a “publicly traded partnership” and certain other requirements are met. A partnership or limited liability company would be treated as a publicly traded partnership if its interests are traded on an established securities market or are readily tradable on a secondary market or a substantial equivalent thereof, within the meaning of applicable Treasury Regulations. We do not anticipate that our operating partnership or any subsidiary partnership or limited liability company will be treated as a publicly traded partnership that is taxable as a corporation. However, if any such entity were treated as a corporation, it would be required to pay an entity-level tax on its income. In this situation, the character of our assets and items of gross income would change and could prevent us from satisfying the REIT asset tests and possibly the REIT income tests. See “—Taxation of Our Company—Asset Tests” and “—Income Tests.” This, in turn, could prevent us from qualifying as a REIT. See “—Failure to Qualify” for a discussion of the effect of our failure to meet these tests. In addition, a change in the tax status of our operating partnership or a subsidiary partnership or limited liability company might be treated as a taxable event. If so, we might incur a tax liability without any related cash payment. We believe our operating partnership and each of our other partnerships and limited liability companies have been and will continue to be treated as partnerships or disregarded entities for federal income tax purposes.

Allocations of Income, Gain, Loss and Deduction. The operating partnership agreement generally provides that allocations of net income will be made first to holders of series A preferred units to the extent of the accrued preferred return on such units and then to us to the extent of the accrued preferred return on our series B

preferred units. To the extent we issue a new class of preferred stock, we expect to contribute the net proceeds from such issuance to the operating partnership in exchange for a new class of preferred units, which will be entitled to allocations of net income in accordance with their terms. Any remaining net income will be allocated to holders of common units. Allocations to holders of common units will generally be made proportionately to all such holders in respect of such units. Certain limited partners have guaranteed debt of our operating partnership, indirectly through an agreement to make capital contributions to our operating partnership under limited circumstances. As a result of these guaranties or contribution agreements, and notwithstanding the foregoing discussion of allocations of income and loss of our operating partnership to holders of units, such limited partners could under limited circumstances be allocated a disproportionate amount of net loss upon a liquidation of our operating partnership, which net loss would have otherwise been allocable to us.

If an allocation of partnership income or loss does not comply with the requirements of Section 704(b) of the Code and the Treasury Regulations thereunder, the item subject to the allocation will be reallocated in accordance with the partners’ interests in the partnership. This reallocation will be determined by taking into account all of the facts and circumstances relating to the economic arrangement of the partners with respect to such item. Our operating partnership’s allocations of taxable income and loss are intended to comply with the requirements of Section 704(b) of the Code and the Treasury Regulations thereunder.

Tax Allocations With Respect to the Properties. Under Section 704(c) of the Code, income, gain, loss and deduction attributable to appreciated or depreciated property that is contributed to a partnership in exchange for an interest in the partnership, must be allocated in a manner so that the contributing partner is charged with the unrealized gain or benefits from the unrealized loss associated with the property at the time of the contribution. The amount of the unrealized gain or unrealized loss generally is equal to the difference between the fair market value or book value and the adjusted tax basis of the contributed property at the time of contribution, as adjusted from time to time. These allocations are solely for federal income tax purposes and do not affect the book capital accounts or other economic or legal arrangements among the partners.

Our operating partnership may, from time to time, acquire interests in property in exchange for interests in our operating partnership. In that case, the tax basis of these property interests generally carries over to the operating partnership, notwithstanding their different book (i.e., fair market) value (this difference is referred to as a book-tax difference). The partnership agreement requires that income and loss allocations with respect to these properties be made in a manner consistent with Section 704(c) of the Code. Treasury Regulations issued under Section 704(c) of the Code provide partnerships with a choice of several methods of accounting for book-tax differences. Depending on the method we choose in connection with any particular contribution, the carryover basis of each of the contributed interests in the properties in the hands of our operating partnership (i) will or could cause us to be allocated lower amounts of depreciation deductions for tax purposes than would be allocated to us if any of the contributed properties were to have a tax basis equal to its respective fair market value at the time of the contribution and (ii) could cause us to be allocated taxable gain in the event of a sale of such contributed interests or properties in excess of the economic or book income allocated to us as a result of such sale, with a corresponding benefit to the other partners in our operating partnership. An allocation described in clause (ii) above might cause us or the other partners to recognize taxable income in excess of cash proceeds in the event of a sale or other disposition of property, which might adversely affect our ability to comply with the REIT distribution requirements. See “—General—Requirements for Qualification as a REIT” and “—Annual Distribution Requirements.”

Any property acquired by our operating partnership in a taxable transaction will initially have a tax basis equal to its fair market value, and Section 704(c) of the Code generally will not apply.

The following summary describes the principal federal income tax consequences to you of acquiring, owning and disposing of our capital stock. This summary assumes you hold shares of our capital stock as a “capital asset” (generally, property held for investment within the meaning of Section 1221 of the Code). It does

not address all the tax consequences that may be relevant to you in light of your particular circumstances. In addition, this discussion does not address the tax consequences relevant to persons who receive special treatment under the federal income tax law, except where specifically noted. Holders receiving special treatment include, without limitation:

If you are considering acquiring our capital stock, you should consult your tax advisor concerning the application of federal income tax laws to your particular situation as well as any consequences of the acquisition, ownership and disposition of our capital stock arising under the laws of any state, local or non-U.S. taxing jurisdiction.

When we use the term “U.S. stockholder,” we mean a holder of shares of our capital stock who, for federal income tax purposes, is:

If you are an individual, corporation, estate or trust that holds shares of our capital stock and you are not a U.S. stockholder, you are a “non-U.S. stockholder.”

If a partnership or other entity treated as a partnership for federal income tax purposes holds shares of our capital stock, the tax treatment of a partner generally will depend on the status of the partner and on the activities of the partnership. Partners of partnerships holding shares of our capital stock are encouraged to consult their tax advisors.

Distributions Generally. Distributions out of our current or accumulated earnings and profits will be treated as dividends and, other than with respect to capital gain dividends and certain amounts which have previously been subject to corporate level tax discussed below, will be taxable to our taxable U.S. stockholders as ordinary income when actually or constructively received. See “—Tax Rates” below. As long as we qualify as a REIT, these distributions will not be eligible for the dividends-received deduction in the case of U.S. stockholders that are corporations or, except to the extent provided in “—Tax Rates” below, the preferential rates on qualified dividend income applicable to non-corporate U.S. stockholders, including individuals. For purposes of determining whether distributions to holders of our capital stock are out of our current or accumulated earnings and profits, our earnings and profits will be allocated first to our outstanding preferred stock and then to our outstanding common stock.

To the extent that we make distributions on our capital stock in excess of our current and accumulated earnings and profits allocable to such stock, these distributions will be treated first as a tax-free return of capital to a U.S. stockholder. This treatment will reduce the U.S. stockholder’s adjusted tax basis in such shares of stock by the amount of the distribution, but not below zero. Distributions in excess of our current and accumulated earnings and profits and in excess of a U.S. stockholder’s adjusted tax basis in its shares will be taxable as capital gain. Such gain will be taxable as long-term capital gain if the shares have been held for more than one year. Dividends we declare in October, November, or December of any year and which are payable to a stockholder of record on a specified date in any of these months will be treated as both paid by us and received by the stockholder on December 31 of that year, provided we actually pay the dividend on or before January 31 of the following year. U.S. stockholders may not include in their own income tax returns any of our net operating losses or capital losses.

U.S. stockholders that receive taxable stock dividends, including dividends partially payable in our capital stock and partially payable in cash, would be required to include the full amount of the dividend (i.e., the cash and the stock portion) as ordinary income (subject to limited exceptions) to the extent of our current and accumulated earnings and profits for U.S. federal income tax purposes, as described above. The amount of any dividend payable in our capital stock generally is equal to the amount of cash that could have been received instead of the capital stock. Depending on the circumstances of a U.S. stockholder, the tax on the distribution may exceed the amount of the distribution received in cash, in which case such U.S. stockholder would have to pay the tax using cash from other sources. If a U.S. stockholder sells the capital stock it received in connection with a taxable stock dividend in order to pay this tax and the proceeds of such sale are less than the amount required to be included in income with respect to the stock portion of the dividend, such U.S. stockholder could have a capital loss with respect to the stock sale that could not be used to offset such dividend income. A U.S. stockholder that receives capital stock pursuant to a distribution generally has a tax basis in such capital stock equal to the amount of cash that could have been received instead of such capital stock as described above, and has a holding period in such capital stock that begins on the day immediately following the payment date for the distribution.

Capital Gain Dividends. Dividends that we properly designate as capital gain dividends will be taxable to our taxable U.S. stockholders as a gain from the sale or disposition of a capital asset held for more than one year, to the extent that such gain does not exceed our actual net capital gain for the taxable year. U.S. stockholders that are corporations may, however, be required to treat up to 20% of certain capital gain dividends as ordinary income. If we properly designate any portion of a dividend as a capital gain dividend, then, except as otherwise required by law, we presently intend to allocate a portion of the total capital gain dividends paid or made available to holders of all classes of our capital stock for the year to the holders of each class of our capital stock in proportion to the amount that our total dividends, as determined for U.S. federal income tax purposes, paid or made available to the holders of each such class of our capital stock for the year bears to the total dividends, as determined for U.S. federal income tax purposes, paid or made available to holders of all classes of our capital stock for the year.

Retention of Net Capital Gains. We may elect to retain, rather than distribute as a capital gain dividend, all or a portion of our net capital gains. If we make this election, we would pay tax on our retained net capital gains. In addition, to the extent we so elect, our earnings and profits (determined for federal income tax purposes) would be adjusted accordingly, and a U.S. stockholder generally would:

Passive Activity Losses and Investment Interest Limitations. Distributions we make and gain arising from the sale or exchange by a U.S. stockholder of our shares will not be treated as passive activity income. As a result, U.S. stockholders generally will not be able to apply any “passive losses” against this income or gain. A U.S. stockholder may elect to treat capital gain dividends, capital gains from the disposition of our stock and income designated as qualified dividend income, described in “—Tax Rates” below, as investment income for purposes of computing the investment interest limitation, but in such case, the stockholder will be taxed at ordinary income rates on such amount. Other distributions made by us, to the extent they do not constitute a return of capital, generally will be treated as investment income for purposes of computing the investment interest limitation.

Dispositions of Our Capital Stock. Except as described below under “—Redemption or Repurchase by Us,” if a U.S. stockholder sells or disposes of shares of capital stock, it will recognize gain or loss for federal income tax purposes in an amount equal to the difference between the amount of cash and the fair market value of any property received on the sale or other disposition and the holder’s adjusted basis in the shares. This gain or loss, except as provided below, will be a long-term capital gain or loss if the holder has held such capital stock for more than one year. However, if a U.S. stockholder recognizes a loss upon the sale or other disposition of capital stock that it has held for six months or less, after applying certain holding period rules, the loss recognized will be treated as a long-term capital loss to the extent the U.S. stockholder received distributions from us which were required to be treated as long-term capital gains.

Redemption or Repurchase by Us. A redemption or repurchase of shares of our capital stock will be treated under Section 302 of the Code as a distribution (and taxable as a dividend to the extent of our current and accumulated earnings and profits as described above under “—Distributions Generally”) unless the redemption or repurchase satisfies one of the tests set forth in Section 302(b) of the Code and is therefore treated as a sale or exchange of the redeemed or repurchased shares. The redemption or repurchase generally will be treated as a sale or exchange if it:

In determining whether any of these tests have been met, shares of capital stock, including common stock and other equity interests in us, considered to be owned by the U.S. stockholder by reason of certain constructive

ownership rules set forth in the Code, as well as shares of our capital stock actually owned by the U.S. stockholder, must generally be taken into account. Because the determination as to whether any of the alternative tests of Section 302(b) of the Code will be satisfied with respect to the U.S. stockholder depends upon the facts and circumstances at the time that the determination must be made, U.S. stockholders are advised to consult their tax advisors to determine such tax treatment.

If a redemption or repurchase of shares of our capital stock is treated as a distribution, the amount of the distribution will be measured by the amount of cash and the fair market value of any property received. See “—Distributions Generally” above. A U.S. stockholder’s adjusted tax basis in the redeemed or repurchased shares generally will be transferred to the U.S. shareholder’s remaining shares of our capital stock, if any. If the U.S. stockholder owns no other shares of our capital stock, under certain circumstances, such basis may be transferred to a related person or it may be lost entirely. Proposed Treasury Regulations issued in 2009, if enacted in their current form, would affect the basis recovery rules described above. It is not clear whether these proposed regulations will be enacted in their current form or at all. Prospective investors should consult their tax advisors regarding the federal income tax consequences of a redemption or repurchase of our capital stock.

If a redemption or repurchase of shares of our capital stock is not treated as a distribution, it will be treated as a taxable sale or exchange in the manner described under “—Dispositions of Our Capital Stock.”

Tax Rates. The maximum tax rate for non-corporate taxpayers for (1) long-term capital gains, including certain “capital gain dividends,” is generally 20% (although depending on the characteristics of the assets which produced these gains and on designations which we may make, certain capital gain dividends may be taxed at a 25% rate) and (2) “qualified dividend income” is generally 20%. In general, dividends payable by REITs are not eligible for the reduced tax rate on qualified dividend income, except to the extent that certain holding period requirements have been met and the REIT’s dividends are attributable to dividends received from taxable corporations (such as its taxable REIT subsidiaries) or to income that was subject to tax at the corporate/REIT level (for example, if the REIT distributed taxable income that it retained and paid tax on in the prior taxable year). In addition, U.S. stockholders that are corporations may be required to treat up to 20% of some capital gain dividends as ordinary income.

Medicare Tax on Unearned Income. Certain U.S. stockholders that are individuals, estates or trusts are required to pay an additional 3.8% tax on, among other things, dividends on and capital gains from the sale or other disposition of stock. U.S. stockholders should consult their tax advisors regarding the effect, if any, of these rules on their ownership and disposition of our capital stock.

Foreign Accounts. Certain payments made to “foreign financial institutions” in respect of accounts of U.S. stockholders at such financial institutions may be subject to withholding at a rate of 30%. U.S. stockholders should consult their tax advisors regarding the effect, if any, of these withholding rules on their ownership and disposition of our capital stock. See “—Taxation of Non-U.S. Stockholders—Foreign Accounts.”

Information Reporting and Backup Withholding. We are required to report to our U.S. stockholders and the IRS the amount of dividends paid during each calendar year, and the amount of any tax withheld. Under the backup withholding rules, a stockholder may be subject to backup withholding with respect to dividends paid unless the holder is a corporation or comes within certain other exempt categories and, when required, demonstrates this fact, or provides a taxpayer identification number, certifies as to no loss of exemption from backup withholding, and otherwise complies with applicable requirements of the backup withholding rules. A U.S. stockholder that does not provide us with its correct taxpayer identification number may also be subject to penalties imposed by the IRS. Backup withholding is not an additional tax. Any amount paid as backup withholding will be creditable against the stockholder’s federal income tax liability, provided the required information is timely furnished to the IRS. In addition, we may be required to withhold a portion of capital gain distributions to any stockholders who fail to certify their non-foreign status. See “—Taxation of Non-U.S. Stockholders.”

Dividend income from us and gain arising upon a sale of our shares generally should not be unrelated business taxable income, or UBTI, to a tax-exempt stockholder, except as described below. This income or gain generally will be UBTI, however, if a tax-exempt stockholder holds its shares as “debt-financed property” within the meaning of the Code. Generally, “debt-financed property” is property the acquisition or holding of which was financed through a borrowing by the tax-exempt stockholder.

For tax-exempt stockholders that are social clubs, voluntary employee benefit associations, supplemental unemployment benefit trusts, or qualified group legal services plans exempt from federal income taxation under Sections 501(c)(7), (c)(9), (c)(17) or (c)(20) of the Code, respectively, income from an investment in our shares will constitute UBTI unless the organization is able to properly claim a deduction for amounts set aside or placed in reserve for specific purposes so as to offset the income generated by its investment in our shares. These prospective investors should consult their tax advisors concerning these “set aside” and reserve requirements.

Notwithstanding the above, however, a portion of the dividends paid by a “pension-held REIT” may be treated as unrelated business taxable income as to certain trusts that hold more than 10%, by value, of the interests in the REIT. A REIT will not be a “pension-held REIT” if it is able to satisfy the “not closely held” requirement without relying on the “look-through” exception with respect to certain trusts or if such REIT is not “predominantly held” by “qualified trusts.” As a result of restrictions on ownership and transfer of our stock contained in our charter, we do not expect to be classified as a “pension-held REIT,” and as a result, the tax treatment described above should be inapplicable to our stockholders. However, because our common stock and our series B preferred stock are (and, we anticipate, will continue to be) publicly traded, we cannot guarantee that this will always be the case.

The following discussion addresses the rules governing federal income taxation of the acquisition, ownership and disposition of our capital stock by non-U.S. stockholders. These rules are complex, and no attempt is made herein to provide more than a brief summary of such rules. Accordingly, the discussion does not address all aspects of federal income taxation and does not address state, local or non-U.S. tax consequences that may be relevant to a non-U.S. stockholder in light of its particular circumstances. We urge non-U.S. stockholders to consult their tax advisors to determine the impact of federal, state, local and non-U.S. income tax laws on the acquisition, ownership and disposition of shares of our capital stock, including any reporting requirements.

Distributions Generally. Distributions (including any taxable stock dividends) that are neither attributable to gains from sales or exchanges by us of U.S. real property interests, or USRPIs, nor designated by us as capital gain dividends (except as described below) will be treated as dividends of ordinary income to the extent that they are made out of our current or accumulated earnings and profits. Such distributions ordinarily will be subject to withholding of federal income tax at a 30% rate or such lower rate as may be specified by an applicable income tax treaty, unless the distributions are treated as effectively connected with the conduct by the non-U.S. stockholder of a U.S. trade or business. Under certain treaties, however, lower withholding rates generally applicable to dividends do not apply to dividends from a REIT. Certain certification and disclosure requirements must be satisfied to be exempt from withholding under the effectively connected income exemption. Dividends that are treated as effectively connected with a U.S. trade or business will generally not be subject to withholding but will be subject to federal income tax on a net basis at graduated rates, in the same manner as dividends paid to U.S. stockholders are subject to federal income tax. Any such dividends received by a non-U.S. stockholder that is a corporation may also be subject to an additional branch profits tax at a 30% rate (applicable after deducting federal income taxes paid on such effectively connected income) or such lower rate as may be specified by an applicable income tax treaty.

Except as otherwise provided below, we expect to withhold federal income tax at the rate of 30% on any distributions made to a non-U.S. stockholder unless:

Distributions in excess of our current and accumulated earnings and profits will not be taxable to a non-U.S. stockholder to the extent that such distributions do not exceed the adjusted basis of the stockholder’s capital stock, but rather will reduce the adjusted basis of such stock. To the extent that such distributions exceed the non-U.S. stockholder’s adjusted basis in such capital stock, they will give rise to gain from the sale or exchange of such stock, the tax treatment of which is described below. For withholding purposes, we expect to treat all distributions as made out of our current or accumulated earnings and profits. However, amounts withheld may be refundable if it is subsequently determined that the distribution was, in fact, in excess of our current and accumulated earnings and profits, provided that certain conditions are met.

Capital Gain Dividends and Distributions Attributable to a Sale or Exchange of U.S. Real Property Interests. Distributions to a non-U.S. stockholder that we properly designate as capital gain dividends, other than those arising from the disposition of a USRPI, generally should not be subject to federal income taxation, unless:

Pursuant to the Foreign Investment in Real Property Tax Act, which is referred to as “FIRPTA,” distributions to a non-U.S. stockholder that are attributable to gain from sales or exchanges by us of USRPIs, whether or not designated as capital gain dividends, will cause the non-U.S. stockholder to be treated as recognizing such gain as income effectively connected with a U.S. trade or business. Non-U.S. stockholders would generally be taxed at the same rates applicable to U.S. stockholders, subject to any applicable alternative minimum tax. We also will be required to withhold and to remit to the IRS 35% (or 20% to the extent provided in Treasury Regulations) of any distribution to non-U.S. stockholders that is designated as a capital gain dividend or, if greater, 35% of any distribution to non-U.S. stockholders that could have been designated as a capital gain dividend. The amount withheld is creditable against the non-U.S. stockholder’s federal income tax liability. However, any distribution with respect to any class of stock that is “regularly traded” on an established securities market located in the United States is not subject to FIRPTA, and therefore, not subject to the 35% U.S. withholding tax described above, if the non-U.S. stockholder did not own more than 5% of such class of stock at any time during the one-year period ending on the date of the distribution. Instead, such distributions will generally be treated as ordinary dividend distributions and subject to withholding in the manner described above with respect to ordinary dividends.

Retention of Net Capital Gains. Although the law is not clear on the matter, it appears that amounts we designate as retained net capital gains in respect of the capital stock held by stockholders generally should be treated with respect to non-U.S. stockholders in the same manner as actual distributions of capital gain dividends. Under this approach, the non-U.S. stockholders would be able to offset as a credit against their federal income tax liability their proportionate share of the tax that we paid on such retained net capital gains and to receive from the IRS a refund to the extent their proportionate share of such tax that we paid exceeds their actual federal income tax liability. If we were to designate any portion of our net capital gain as retained net capital gain, a non-U.S. stockholder should consult its tax advisor regarding the taxation of such retained net capital gain.

Sale of Our Capital Stock. Except as described below under “—Redemption or Repurchase by Us,” gain recognized by a non-U.S. stockholder upon the sale, exchange or other taxable disposition of our capital stock generally will not be subject to federal income taxation unless such stock constitutes a USRPI. In general, stock of a domestic corporation that constitutes a “U.S. real property holding corporation,” or USRPHC, will constitute a USRPI. We believe that we are a USRPHC. Our capital stock will not, however, constitute a USRPI so long as we are a “domestically controlled qualified investment entity.” A “domestically controlled qualified investment entity” includes a REIT in which at all times during a specified testing period less than 50% in value of its stock is held directly or indirectly by non-U.S. persons. We believe, but cannot guarantee, that we are a “domestically controlled qualified investment entity.” Because our common stock and our series B preferred stock are (and, we anticipate, will continue to be) publicly traded, no assurance can be given that we will continue to be a “domestically controlled qualified investment entity.”

Even if we do not qualify as a “domestically controlled qualified investment entity” at the time a non-U.S. stockholder sells our capital stock, gain arising from the sale or other taxable disposition by a non-U.S. stockholder of such stock would not be subject to federal income taxation under FIRPTA as a sale of a USRPI if:

Notwithstanding the foregoing, gain from the sale, exchange or other taxable disposition of our capital stock not otherwise subject to FIRPTA will be taxable to a non-U.S. stockholder if either (a) the investment in our capital stock is treated as effectively connected with the non-U.S. stockholder’s U.S. trade or business or (b) the non-U.S. stockholder is a nonresident alien individual who is present in the United States for 183 days or more during the taxable year and certain other conditions are met. In addition, even if we are a domestically controlled qualified investment entity, upon disposition of our capital stock, a non-U.S. stockholder may be treated as having gain from the sale or other taxable disposition of a USRPI if the non-U.S. stockholder (1) disposes of such stock within a 30-day period preceding the ex-dividend date of a distribution, any portion of which, but for the disposition, would have been treated as gain from the sale or exchange of a USRPI and (2) acquires, or enters into a contract or option to acquire, or is deemed to acquire, other shares of that stock during the 61-day period beginning with the first day of the 30-day period described in clause (1), subject to an exception applicable to “regularly traded” stock if the non-U.S. stockholder did not own more than 5% of the stock at any time during the one-year period ending on the date of the distribution described in clause (1).

If gain on the sale, exchange or other taxable disposition of our capital stock were subject to taxation under FIRPTA, the non-U.S. stockholder would be subject to regular federal income tax with respect to such gain in the same manner as a taxable U.S. stockholder (subject to any applicable alternative minimum tax and a special alternative minimum tax in the case of nonresident alien individuals). In addition, if the sale, exchange or other taxable disposition of our capital stock were subject to taxation under FIRPTA, and if shares of our capital stock were not “regularly traded” on an established securities market, the purchaser of such capital stock would generally be required to withhold and remit to the IRS 10% of the purchase price.

Redemption or Repurchase by Us. A redemption or repurchase of shares of our capital stock will be treated under Section 302 of the Code as a distribution (and taxable as a dividend to the extent of our current and accumulated earnings and profits) unless the redemption or repurchase satisfies one of the tests set forth in Section 302(b) of the Code and is therefore treated as a sale or exchange of the redeemed or repurchased shares. See “—Taxation of Taxable U.S. Stockholders—Redemption or Repurchase by Us.” If the redemption or repurchase of shares is treated as a distribution, the amount of the distribution will be measured by the amount of cash and the fair market value of any property received. See “—Taxation of Non-U.S. Stockholders—Distributions Generally.” If the redemption or repurchase of shares is not treated as a distribution, it will be treated as a taxable sale or exchange in the manner described under “—Taxation of Non-U.S. Stockholders—Sale of Our Capital Stock.”

Information Reporting and Backup Withholding Tax. Generally, we must report annually to the IRS the amount of dividends paid to a non-U.S. stockholder, such holder’s name and address, and the amount of tax withheld, if any. A similar report is sent to the non-U.S. stockholder. Pursuant to tax treaties or other agreements, the IRS may make its reports available to tax authorities in the non-U.S. stockholder’s country of residence.

Payments of dividends or of proceeds from the disposition of stock made to a non-U.S. stockholder may be subject to information reporting and backup withholding unless such holder establishes an exemption, for example, by properly certifying its non-U.S. status on an IRS Form W-8BEN, W-8BEN-E or another appropriate version of IRS Form W-8. Notwithstanding the foregoing, backup withholding and information reporting may apply if either we have or our paying agent has actual knowledge, or reason to know, that a non-U.S. stockholder is a U.S. person.

Backup withholding is not an additional tax. Rather, the federal income tax liability of persons subject to backup withholding will be reduced by the amount of tax withheld. If withholding results in an overpayment of taxes, a refund or credit may be obtained, provided that the required information is timely furnished to the IRS.

Foreign Accounts. Withholding taxes may be imposed under Sections 1471 to 1474 of the Code (such Sections commonly referred to as the Foreign Account Tax Compliance Act, or FATCA) on certain types of payments made to non-U.S. financial institutions and certain other non-U.S. entities. Specifically, a 30% withholding tax may be imposed on dividends on, or gross proceeds from the sale or other disposition of, our capital stock paid to a “foreign financial institution” or a “non-financial foreign entity” (each as defined in the Code), unless (1) the foreign financial institution undertakes certain diligence and reporting obligations, (2) the non-financial foreign entity either certifies it does not have any “substantial United States owners” (as defined in the Code) or furnishes identifying information regarding each substantial United States owner, or (3) the foreign financial institution or non-financial foreign entity otherwise qualifies for an exemption from these rules. If the payee is a foreign financial institution and is subject to the diligence and reporting requirements in clause (1) above, it must enter into an agreement with the U.S. Department of the Treasury under which it undertakes, among other things, to identify accounts held by certain “specified United States persons” or “United States-owned foreign entities” (each as defined in the Code), report certain information about such accounts, and withhold 30% on certain payments to non-compliant foreign financial institutions and certain other account holders. Foreign financial institutions located in jurisdictions that have an intergovernmental agreement with the United States governing FATCA may be subject to different rules.

Under the applicable Treasury Regulations, withholding under FATCA generally applies to payments of dividends on our capital stock, and will apply to payments of gross proceeds from the sale or other disposition of such stock on or after January 1, 2017.

Prospective investors should consult their tax advisors regarding the potential application of withholding under FATCA to their investment in our capital stock.

State, local and non-U.S. income tax laws may differ substantially from the corresponding federal income tax laws, and this discussion does not purport to describe any aspect of the tax laws of any state, local or non-U.S. jurisdiction. You should consult your tax advisor regarding the effect of state, local and non-U.S. tax laws with respect to our tax treatment as a REIT, the exercise of redemption rights with respect to the common units, and an investment in our capital stock.

Unless we indicate differently in a prospectus supplement, the securities initially will be issued in book-entry form and represented by one or more global securities. The global securities will be deposited with, or on behalf of, The Depository Trust Company, New York, New York, as depositary, or DTC, and registered in the name of Cede & Co., the nominee of DTC. Unless and until it is exchanged for individual certificates evidencing securities under the limited circumstances described below, a global security may not be transferred except as a whole by the depositary to its nominee or by the nominee to the depositary, or by the depositary or its nominee to a successor depositary or to a nominee of the successor depositary.

DTC holds securities that its participants deposit with DTC. DTC also facilitates the settlement among its participants of securities transactions, such as transfers and pledges, in deposited securities through electronic computerized book-entry changes in participants’ accounts, thereby eliminating the need for physical movement of securities certificates. “Direct participants” in DTC include securities brokers and dealers, including underwriters, banks, trust companies, clearing corporations and other organizations. DTC is a wholly-owned subsidiary of The Depository Trust & Clearing Corporation, or DTCC. DTCC is the holding company for DTC, National Securities Clearing Corporation and Fixed Income Clearing Corporation, all of which are registered clearing agencies. DTCC is owned by the users of its regulated subsidiaries. Access to the DTC system is also available to others, which we sometimes refer to as indirect participants, that clear through or maintain a custodial relationship with a direct participant, either directly or indirectly. The rules applicable to DTC and its participants are on file with the Securities and Exchange Commission.

Purchases of securities under the DTC system must be made by or through direct participants, which will receive a credit for the securities on DTC’s records. The ownership interest of the actual purchaser of a security, which we sometimes refer to as a beneficial owner, is in turn recorded on the direct and indirect participants’ records. Beneficial owners of securities will not receive written confirmation from DTC of their purchases. However, beneficial owners are expected to receive written confirmations providing details of their transactions, as well as periodic statements of their holdings, from the direct or indirect participants through which they purchased securities. Transfers of ownership interests in global securities are to be accomplished by entries made on the books of participants acting on behalf of beneficial owners. Beneficial owners will not receive certificates representing their ownership interests in the global securities, except under the limited circumstances described below.

To facilitate subsequent transfers, all global securities deposited by direct participants with DTC will be registered in the name of DTC’s partnership nominee, Cede & Co., or such other name as may be requested by an authorized representative of DTC. The deposit of securities with DTC and their registration in the name of Cede & Co. or such other nominee will not change the beneficial ownership of the securities. DTC has no knowledge of the actual beneficial owners of the securities. DTC’s records reflect only the identity of the direct participants to whose accounts the securities are credited, which may or may not be the beneficial owners. The participants are responsible for keeping account of their holdings on behalf of their customers.

So long as the securities are in book-entry form, you will receive payments and may transfer securities only through the facilities of the depositary and its direct and indirect participants. We will maintain an office or agency in the location specified in the prospectus supplement for the applicable securities, where notices and demands in respect of the securities may be delivered to us and where certificated securities may be surrendered for payment, registration of transfer or exchange.

Conveyance of notices and other communications by DTC to direct participants, by direct participants to indirect participants and by direct participants and indirect participants to beneficial owners will be governed by arrangements among them, subject to any legal requirements in effect from time to time.

Redemption notices will be sent to DTC. If less than all of the securities of a particular series are being redeemed, DTC’s practice is to determine by lot the amount of the interest of each direct participant in the securities of such series to be redeemed.

Neither DTC nor Cede & Co. (or such other DTC nominee) will consent or vote with respect to the securities. Under its usual procedures, DTC will mail an omnibus proxy to us as soon as possible after the record date. The omnibus proxy assigns the consenting or voting rights of Cede & Co. to those direct participants to whose accounts the securities of such series are credited on the record date, identified in a listing attached to the omnibus proxy.

So long as securities are in book-entry form, we will make payments on those securities to the depositary or its nominee, as the registered owner of such securities, by wire transfer of immediately available funds. If securities are issued in definitive certificated form under the limited circumstances described below, we will have the option of making payments by check mailed to the addresses of the persons entitled to payment or by wire transfer to bank accounts in the United States designated in writing to the applicable trustee or other designated party at least 15 days before the applicable payment date by the persons entitled to payment, unless a shorter period is satisfactory to the applicable trustee or other designated party.

Redemption proceeds, distributions and dividend payments on the securities will be made to Cede & Co., or such other nominee as may be requested by an authorized representative of DTC. DTC’s practice is to credit direct participants’ accounts upon DTC’s receipt of funds and corresponding detail information from us on the payment date in accordance with their respective holdings shown on DTC records. Payments by participants to beneficial owners will be governed by standing instructions and customary practices, as is the case with securities held for the account of customers in bearer form or registered in “street name.” Those payments will be the responsibility of participants and not of DTC or us, subject to any statutory or regulatory requirements in effect from time to time. Payment of redemption proceeds, distributions and dividend payments to Cede & Co., or such other nominee as may be requested by an authorized representative of DTC, is our responsibility, disbursement of payments to direct participants is the responsibility of DTC, and disbursement of payments to the beneficial owners is the responsibility of direct and indirect participants.

Except under the limited circumstances described below, purchasers of securities will not be entitled to have securities registered in their names and will not receive physical delivery of securities. Accordingly, each beneficial owner must rely on the procedures of DTC and its participants to exercise any rights under the securities.

The laws of some jurisdictions may require that some purchasers of securities take physical delivery of securities in definitive form. Those laws may impair the ability to transfer or pledge beneficial interests in securities.

DTC may discontinue providing its services as securities depositary with respect to the securities at any time by giving reasonable notice to us. Under such circumstances, in the event that a successor depositary is not obtained, securities certificates are required to be printed and delivered.

As noted above, beneficial owners of a particular series of securities generally will not receive certificates representing their ownership interests in those securities. However, if:

we will prepare and deliver certificates for such securities in exchange for beneficial interests in the global securities. Any beneficial interest in a global security that is exchangeable under the circumstances described in the preceding sentence will be exchangeable for securities in definitive certificated form registered in the names that the depositary directs. It is expected that these directions will be based upon directions received by the depositary from its participants with respect to ownership of beneficial interests in the global securities.

We have obtained the information in this section and elsewhere in this prospectus concerning DTC and DTC’s book-entry system from sources that are believed to be reliable, but we take no responsibility for the accuracy of this information.

Information about selling securityholders, where applicable, will be set forth in a prospectus supplement, in a post-effective amendment or in filings we make with the Securities and Exchange Commission under the Exchange Act that are incorporated herein by reference.

Additional legal matters may be passed upon for us, the selling securityholders or any underwriters, dealers or agents, by counsel that we will name in the applicable prospectus supplement.
