FORWARD-LOOKING STATEMENTS

Certain written and oral statements made or incorporated by reference from time to time by us or our representatives in this prospectus, other filings or reports filed with the SEC, press releases, conferences, or otherwise, are “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995 (set forth in Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), and Section 21E of the Exchange Act). In particular, statements relating to our liquidity and capital resources, potential asset dispositions and loan modification efforts, portfolio performance and results of operations contain forward-looking statements. Furthermore, all of the statements regarding future financial performance (including market conditions and demographics) are forward-looking statements. We are including this cautionary statement to make applicable and take advantage of the safe harbor provisions of the Private Securities Litigation Reform Act of 1995 for any such forward-looking statements. We caution investors that any forward-looking statements presented in this prospectus, or that management may make orally or in writing from time to time, are based on management’s beliefs and assumptions made by, and information currently available to, management. When used, the words “anticipate,” “believe,” “expect,” “intend,” “may,” “might,” “plan,” “estimate,” “project,” “should,” “will,” “result” and similar expressions that do not relate solely to historical matters are intended to identify forward-looking statements. Such statements are subject to risks, uncertainties and assumptions and may be affected by known and unknown risks, trends, uncertainties and factors that are beyond our control. Should one or more of these risks or uncertainties materialize, or should underlying assumptions prove incorrect, actual results may vary materially from those anticipated, estimated or projected. We expressly disclaim any responsibility to update forward-looking statements, whether as a result of new information, future events or otherwise. Accordingly, investors should use caution in relying on past forward-looking statements, which were based on results and trends at the time they were made, to anticipate future results or trends.

SELLING SECURITY HOLDERS

The “selling security holders” are the people or entities who may receive shares of our common stock upon exchange of common units. The following table provides the names of the selling security holders, the maximum number of shares of our common stock issuable to such selling security holders in the exchange and the aggregate number of shares of our common stock that will be owned by such selling security holders after the exchange. The number of shares on the following table represents the number of shares of our common stock into which common units held by the selling security holders are exchangeable. Since the selling security holders may sell all, some or none of their shares, we cannot estimate the aggregate number of shares that the selling security holders will offer pursuant to this prospectus or that the selling security holders will own upon completion of the offering to which this prospectus relates.

The selling security holders named below may from time to time offer the shares of our common stock offered by this prospectus:

Assumes that we exchange the common units of the selling security holders for shares of our common stock.

Also assumes that no transactions with respect to our common stock or common units occur other than the exchange. There were 50,753,644 shares of our common stock outstanding as of March 9, 2012 .


(2)	Assumes the selling security holders sell all of their shares of our common stock offered pursuant to this prospectus. The percentage ownership is determined for each selling security holder by taking into account the issuance and sale of shares of our common stock issued in exchange for common units of only such selling security holder.

PLAN OF DISTRIBUTION

This prospectus relates to the offer and sale from time to time of some or all of up to 6,446,777 shares of our common stock by the selling stockholders.

We are registering the resale of the shares of our common stock to provide the holders with freely tradable securities, but the registration of these shares does not necessarily mean that any of these shares will be offered or sold by the holders.

We will not receive any proceeds from the sale of the shares of our common stock by the selling stockholders, but we have agreed to pay the following expenses of the registration of such shares:


•	all registration and filing fees;


•	fees and expenses for complying with securities or blue sky laws, including reasonable fees and disbursements of counsel in connection with blue sky qualifications; and


•	the fees and expenses incurred in connection with listing our common stock on each securities exchange on which our similar securities issued are then listed.

We have no obligation to pay any underwriting fees, discounts or commissions attributable to the exchange of common units for our common stock by the selling stockholders or from the resale of such common stock by the selling stockholders. We also have no obligation to pay any out-of-pocket expenses of the selling stockholders, or the agents who manage their accounts, or any transfer taxes relating to the registration or sale of our common stock contemplated hereby.

The selling stockholders may from time to time sell the shares of our common stock covered by this prospectus directly to purchasers. Alternatively, the selling stockholders may from time to time offer such shares through dealers or agents, who may receive compensation in the form of commissions from the selling stockholders and for the purchasers of such shares for whom they may act as agent. The selling stockholders and any dealers or agents that participate in the distribution of such shares may be deemed to be “underwriters” within the meaning of the Securities Act and any profit on the sale of our common stock by them and any commissions received by any of these dealers or agents might be deemed to be underwriting commissions under the Securities Act.

In connection with distribution of the shares of our common stock covered by this prospectus:


•	the selling stockholders may enter into hedging transactions with broker-dealers;


•	the broker-dealers may engage in short sales of our common stock in the course of hedging the positions they assume with the selling stockholders;


•	the selling stockholders may sell our common stock short and deliver our common stock to close out these short positions;


•	the selling stockholders may enter into option or other transactions with broker-dealers that involve the delivery of our common stock to the broker-dealers, who may then resell or otherwise transfer our common stock; and


•	the selling stockholders may loan or pledge our common stock to a broker-dealer, lender or other person or entity and the broker-dealer, lender or other person or entity may sell our common stock so loaned or upon a default may sell or otherwise transfer the pledged stock.

Table of Contents

Persons participating in the distribution of the shares of our common stock offered by this prospectus may engage in transactions that stabilize the price of our common stock. The anti-manipulation rules of Regulation M under the Exchange Act may apply to sales of our common stock in the market and to the activities of the selling stockholders.

USE OF PROCEEDS

We are filing the registration statement of which this prospectus is a part pursuant to our contractual obligation to the holders of our common units named in the section entitled “Selling Stockholders.” We will not receive any of the proceeds from the resale of shares of our common stock from time to time by such holders. However, we will pay registration expenses, which we estimate to be $169,932 .

Table of Contents

POLICIES WITH RESPECT TO CERTAIN ACTIVITIES

The following is a discussion of certain of our investment, financing and other policies. These policies have been established by our board of directors and, in general, may be amended or revised from time to time by our board of directors without a vote of our stockholders.

Investment Policies

Investments in Real Estate or Interests in Real Estate—

We conduct all of our investment activities through our operating partnership and its subsidiaries. Our investment objectives are to maximize the net operating income of our properties, preserve and generate liquidity, achieve long-term capital appreciation for our stockholders through increases in the value of our company, limit financial risk and provide quarterly cash distributions. We have not established a specific policy regarding the relative priority of these investment objectives.

We expect to pursue our investment objectives primarily through our ownership of developed and undeveloped land. We currently intend to invest primarily in office and commercial properties. Although our current portfolio is concentrated in Southern California office properties, future investment will not be limited to any geographic area or product type, or to a specified percentage of our assets. While we may diversify in terms of property locations, size and market, we do not have any limit on the amount or percentage of our assets that may be invested in any one property or any one geographic area.

We may also participate with third parties in property ownership, through joint ventures or other types of co-ownership. These types of investments may permit us to own interests in larger assets without unduly restricting our diversification and, therefore, provide us with flexibility in structuring our portfolio. We will not, however, enter into a joint venture or other partnership arrangement to make an investment that would not otherwise meet our investment policies.

Investments in our properties are typically subject to mortgages and other indebtedness. Debt service on such indebtedness will have a priority over any dividends with respect to our common stock. Investments are also subject to our policy not to be treated as an investment company under the Investment Company Act of 1940, as amended, or the 1940 Act.

Investments in Real Estate Mortgages—

We do not currently invest in mortgages or deeds of trust but may do so in the future.

Securities of or Interests in Persons Primarily Engaged in Real Estate Activities—

Subject to the ownership limitations and gross income tests necessary for REIT qualification, we may invest in securities of other REITs or other entities engaged in real estate activities, including for the purpose of exercising control over such entities.

Investments in Other Securities—

We do not currently engage in purchasing or selling other securities, other than short-term investments that we view as cash equivalents and that we can hold consistent with our qualification as a REIT, but may do so in the future, as long as doing so does not impact our ability to continue to qualify as a REIT.

Table of Contents

Dispositions

Our board of directors may from time to time determine that disposing of one or more properties would be in our best interests. For example, we may seek to dispose of properties to improve our liquidity position or to reduce our debt level. Any decision to dispose of a property is made by our board of directors. We may be obligated to indemnify certain contributors against adverse tax consequences to them in the event that we dispose of certain properties in taxable transactions under the tax indemnification provisions of the contribution agreements of Robert F. Maguire III and certain other entities.

Financing Policies

Substantially all of our assets are encumbered by one or more loans and we are continuously engaged in efforts to extend, refinance or extinguish such debt. Our charter and bylaws do not limit the amount or percentage of indebtedness that we may incur, and our level of leverage is at our discretion and not subject to stockholder approval. Our board of directors may from time to time modify its views regarding the appropriate amount of debt for our company in light of then-current economic conditions, relative costs of debt and equity capital, market values of our properties, general conditions in the market for debt and equity securities, fluctuations in the market price of our common stock, growth and acquisition opportunities and other factors.

Our indebtedness may be secured or unsecured. Typically, our lenders require that we form special purpose entities to serve as borrowers under our loans. Our debt may be fully or partially recourse to our operating partnership, and may be cross-collateralized with other debt. We do not have a policy limiting the number or amount of mortgages that may be placed on any particular property. However, mortgage documents typically limit additional indebtedness on such properties.

Equity Policies

We have authority to issue common stock, preferred stock, debt securities, units of limited partnership interest in our operating partnership and other securities, and we may do so in the future. In many cases such securities may be issued if authorized by our board of directors without stockholder approval. Existing stockholders will have no preemptive right to common or preferred stock or units issued in any securities offering by us, and any such offering might cause a dilution of a stockholder’s investment. Such securities may be senior to the outstanding classes of common stock and/or may be convertible into common stock.

We also may issue shares of our common stock, or cash at our option, to holders of units of limited partnership interest in our operating partnership upon any redemption of such units.

We may, under certain circumstances, purchase or exchange shares of our common stock or preferred stock in the open market or in private transactions with our stockholders, provided that those purchases or exchanges are approved by our board of directors. Any such action would be structured so as to conform to applicable laws and regulations.

Lending Policies

Our policies prohibit us from making any loans to our directors or executive officers for any purpose. We have made and may in the future make de minimis loans to non-executive employees. We do not have a policy limiting our ability to make loans to third parties. We may consider offering purchase money financing in connection with the sale of properties in the event that the provision of that financing will increase the value to be received by us for the property sold. We also may make loans to joint ventures in which we participate. However, we do not intend to engage in significant lending activities.

Table of Contents

Conflict of Interest Policies

Conflicts of interest could arise as a result of the relationships between us and our affiliates, on the one hand, and our operating partnership or any partner thereof, on the other. Our directors and officers have duties to our company under applicable Maryland law in connection with their management of our company. At the same time, we, as the general partner of our operating partnership, have duties and obligations to our operating partnership and its limited partners under Maryland law in connection with the management of our operating partnership. Our duties and obligations as general partner to our operating partnership and its partners may come into conflict with the duties of our directors and officers to our company.

We have adopted various corporate governance policies and documents designed to reduce or eliminate potential conflicts of interest, including written charters for each of the committees of our board of directors and a code of business conduct and ethics that applies to all of our officers, directors and employees.

Interested Director and Officer Transactions

Pursuant to Maryland law, a contract or other transaction between us and a director or between us and any other corporation or other entity in which any of our directors is a director or has a material financial interest is not void or voidable solely on the grounds of such common directorship or interest. The common directorship or interest, the presence of such director at the meeting at which the contract or transaction is authorized, approved or ratified or the counting of the director’s vote in favor thereof will not render the contract or transaction void or voidable if:


•	the fact of the common directorship or interest is disclosed or known to our board of directors or a committee of our board, and our board or such committee authorizes, approves or ratifies the transaction or contract by the affirmative vote of a majority of disinterested directors, even if the disinterested directors constitute less than a quorum;


•	the fact of the common directorship or interest is disclosed or known to our stockholders entitled to vote thereon, and the contract or transaction is authorized, approved or ratified by a majority of the votes cast by the disinterested stockholders entitled to vote; or


•	the transaction or contract is fair and reasonable to us.

Furthermore, under Maryland law, we, as general partner, have a duty to our operating partnership and, consequently, such transactions also are subject to the duties of care and loyalty that we, as general partner, owe to limited partners in our operating partnership (to the extent such duties have not been eliminated pursuant to the terms of the partnership agreement).

We have established a written related party transaction policy to monitor interested director or officer transactions, arrangements or relationships. Under the policy, potential related party transactions are identified by our senior management and the relevant details and analysis of the transaction are presented to our board of directors. If a member of our senior management has an interest in a potential related party transaction, all relevant information is provided to our Chief Executive Officer, his designee or a designated officer without any interest in the transaction (as the case may be), who will review the proposed transaction (generally with assistance from our General Counsel or outside counsel) and then present the matter and his or her conclusions to our board of directors.

The independent members of our board of directors review the material facts of any potential related party transaction and then approve or disapprove the transaction. In making its determination, our board of directors considers such factors as (1) the extent of the related person’s interest in the related party transaction, (2) if applicable, the availability of other sources or comparable products or services, (3) whether the terms of the related party transaction are no less favorable than terms generally available in unaffiliated transactions under like circumstances, (4) the benefit to our company, (5) the aggregate value of the related party transaction, and (6) such

Table of Contents

other factors it deems appropriate. No director may engage in any discussion or approval of any related party transaction in which he or she is a related person; provided, however, that such director must provide our board of directors with all material information reasonably requested concerning the related party transaction.

Where appropriate in the judgment of the disinterested directors, our board of directors may obtain a fairness opinion or engage independent counsel to represent the interests of non-affiliated security holders, although our board of directors will have no obligation to do so.

Business Opportunities

Pursuant to Maryland law, each director is obligated to offer to us any business opportunity (with certain limited exceptions) that comes to such director in his or her capacity as a director and those we reasonably could be expected to have an interest in pursuing.

REIT Qualification

We intend to implement the policies above in a manner consistent with our qualification as a REIT, unless the board of directors determines that it is no longer in our best interests to qualify as a REIT. Our board of directors may make such a determination because of changing circumstances or changes in the REIT requirements.

Reporting Policies

We are subject to the information reporting requirements of the Exchange Act. Pursuant to such requirements, we are required to file annual and periodic reports, proxy statements and other information, including audited financial statements, with the SEC. We have filed such reports with the SEC since 2003.

Other than normally recurring capital expenditures, we have no specific immediate plans with respect to major renovations or a redevelopment of Two California Plaza.

Two California Plaza is encumbered with mortgage debt. Our special purpose property-owning subsidiary that owns Two California Plaza is in default for failing to make debt service payments due under this loan. The special servicer for this loan has accelerated the debt, but has not foreclosed on the property. We no longer believe we will be able to successfully modify the Two California Plaza mortgage loan and retain an ownership interest in the asset. We expect that Two California Plaza will be placed into receivership in the near term pursuant to a consensual agreement and we will focus on an orderly exit from the asset.

U.S. FEDERAL INCOME TAX CONSIDERATIONS

The following is a summary of certain material U.S. federal income tax consequences relating to our election to be taxed as a REIT and the acquisition, ownership and disposition of our common stock. This summary is for general information only and is not tax advice.

This information is based on:


•	the Internal Revenue Code of 1986, as amended, or the Code;


•	current, temporary and proposed Treasury Regulations promulgated under the Code;


•	the legislative history of the Code;


•	administrative interpretations and practices of the Internal Revenue Service, or the IRS; and


•	court decisions;

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. The sections of the Code and the corresponding Treasury Regulations that relate to the federal income tax treatment of REITs and their stockholders are highly technical and complex. The following discussion sets forth certain material aspects of the sections of the Code that govern the U.S. federal income tax treatment of a REIT and its stockholders. This summary is qualified in its entirety by the applicable Code provisions, the Treasury Regulations, and related administrative and judicial interpretations thereof. 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 plan to request, any rulings from the IRS concerning our tax treatment with respect to matters contained in this discussion, 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 summary 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 acquisition, ownership, sale or other disposition of our common stock or our election to be taxed as a REIT.

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


•	the acquisition, ownership and sale or other disposition of our common stock, including the U.S. federal, state, local, foreign and other tax consequences;


•	our election to be taxed as a REIT for U.S. federal income tax purposes; and


•	potential changes in applicable tax laws.

Taxation of Our Company

General . We elected to be taxed as a REIT under Sections 856 through 860 of the Code, commencing with our taxable year ended December 31, 2003. We believe that we have been organized and have operated in a manner which has allowed us to qualify for taxation as a REIT under the Code commencing with our taxable year ended December 31, 2003, 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

Table of Contents

continue to be organized and operate, in a manner so as to qualify or remain qualified as a REIT. See “—Failure to Qualify.”

Latham & Watkins LLP has acted as our tax counsel in connection with this prospectus. Latham & Watkins LLP rendered an opinion to us on April 30, 2010 in connection with the original filing of this prospectus to the effect that, commencing with our taxable year ended December 31, 2003, 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 U.S. federal income tax treatment described in this prospectus may be changed, perhaps retroactively, by legislative, administrative or judicial action at any time. Latham & Watkins LLP has no obligation to update, and has not updated, its opinion subsequent to its date.

Provided we qualify for taxation as a REIT, we generally will not be required to pay U.S. 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:


•	first, we will be required to pay tax at regular corporate rates on any undistributed REIT taxable income, including undistributed net capital gains;


•	second, we may be required to pay the “alternative minimum tax” on our items of tax preference under some circumstances;

•

third, if we have (1) net income from the sale or other disposition of “foreclosure property” which is held primarily for sale to customers in the ordinary course of business or (2) other nonqualifying income from foreclosure property, we will be required to pay tax at the highest corporate rate on this income. To the extent that income from foreclosure property is otherwise qualifying income for purposes of the 75% gross income test, this tax is not applicable. Foreclosure property generally is defined as property we acquired through foreclosure or after a default on a loan secured by the property or a lease of the property and for which an election is in effect;


•	fourth, we will be required to pay a 100% tax on any net income from prohibited transactions. Prohibited transactions are, in general, sales or other taxable dispositions of property, other than foreclosure property, held as inventory or primarily for sale to customers in the ordinary course of business;

•

fifth, if we fail to satisfy the 75% gross income test or the 95% gross income test, as discussed below, but have otherwise maintained our qualification as a REIT because certain other requirements are met, we will be required to pay a tax equal to (1) the greater of (a) the amount by which 75% of our gross income exceeds the amount qualifying under the 75% gross income test and (b) the amount by which 95% of our gross income (90% for our taxable years ending on or before December 31, 2004) exceeds the amount qualifying under the 95% gross income test, multiplied by (2) a fraction intended to reflect our profitability;

Table of Contents

•

sixth, if we fail to satisfy any of the REIT asset tests (other than a de minimis failure of the 5% or 10% asset test), as described below, due to reasonable cause and not due to willful neglect, and we nonetheless maintain our REIT qualification because of specified cure provisions, we will be required to pay a tax equal to the greater of $50,000 or the highest corporate tax rate multiplied by the net income generated by the nonqualifying assets that caused us to fail such test;

•

seventh, if we fail to satisfy any provision of the Code that would result in our failure to qualify as a REIT (other than a violation of the REIT gross income tests or certain violations of the asset tests described in more detail below) and the violation is due to reasonable cause, and not due to willful neglect, we may retain our REIT qualification but we will be required to pay a penalty of $50,000 for each such failure;


•	eighth, 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 (1) 85% of our REIT ordinary income for the year, (2) 95% of our REIT capital gain net income for the year, and (3) any undistributed taxable income from prior periods;

•

ninth, if we acquire any asset from a corporation which is or has been a C corporation in a transaction in which the basis of the asset in our hands is determined by reference to the basis of the asset in the hands of the C corporation, and we subsequently recognize gain on the disposition of the asset during the ten-year period beginning on the date on which we acquired the asset, then we will be required to pay tax at the highest regular corporate tax rate on this gain to the extent of the excess of (1) the fair market value of the asset over (2) our adjusted basis in the asset, in each case determined as of the date on which we acquired the asset. The results described in this paragraph with respect to the recognition of gain assume that the C corporation will refrain from making an election to receive different treatment under existing Treasury Regulations on its tax return for the year in which we acquire the asset from the C corporation;


•	tenth, from time to time, we may own certain subsidiaries that are C corporations, such as a taxable REIT subsidiary, which generally will be required to pay federal corporate income tax on their earnings;

•

eleventh, we will be required to pay a 100% tax on any “redetermined rents,” “redetermined deductions” or “excess interest.” See “—Penalty Tax.” In general, redetermined rents are rents from real property that are overstated as a result of services furnished to any of our tenants by a “taxable REIT subsidiary” of ours. Redetermined deductions and excess interest generally represent 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; and


•	twelfth, we may be required to pay penalties to the IRS in certain circumstances, including if we fail to meet recordkeeping requirements intended to monitor our compliance with rules relating to the composition of our stockholders.

We and our subsidiaries may be subject to a variety of taxes other than U.S. federal income tax, including payroll taxes and state and local income, property and other taxes on our assets and operations.

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


(1)	that is managed by one or more trustees or directors;


(2)	that issues transferable shares or transferable certificates to evidence its beneficial ownership;


(3)	that would be taxable as a domestic corporation, but for Sections 856 through 860 of the Code;

Table of Contents


(4)	that is not a financial institution or an insurance company within the meaning of certain provisions of the Code;


(5)	that is beneficially owned by 100 or more persons;


(6)	not more than 50% in value of the outstanding stock of which is owned, actually or constructively, by five or fewer individuals, including specified entities, during the last half of each taxable year; and


(7)	that meets other tests, described below, regarding the nature of its income and assets and the amount of its distributions.

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 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, have operated and have issued sufficient shares of common stock with sufficient diversity of ownership 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 which are intended to assist us in continuing to satisfy the share ownership requirements described in (5) and (6) above. A description of the transfer restrictions relating to our outstanding common stock is contained in this prospectus under the heading “Restrictions on Transfer.” These restrictions, however, may not ensure that we will, in all cases, be able to satisfy the share ownership requirements described in (5) and (6) above. If we fail to satisfy these share ownership requirements, except as provided in the next two sentences, 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. Moreover, if our failure to satisfy the share ownership requirements is due to reasonable cause and not willful neglect, we may retain our REIT qualification but will be required to pay a penalty of $50,000 for each such failure. 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 which is a partner in a partnership or a member in a limited liability company treated as a partnership for U.S. 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% REIT 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 REIT gross income tests and the REIT 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 U.S. 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 REIT gross income and REIT 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,

Table of Contents

the Subsidiary Partnerships and the Limited Liability Companies.”

We have control of our operating partnership and indirect control of some of 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. We may from time to time be a limited partner or non-managing member in some of our partnerships and limited liability companies. If a partnership or limited liability company in which we own an interest 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 REIT 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 wholly-owned 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 if we do not elect with the subsidiary to treat it as a “taxable REIT subsidiary,” as described below. A corporation that is a qualified REIT subsidiary is not treated as a separate corporation for U.S. federal income tax purposes, 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 (as the case may be) of the parent REIT for all purposes under the Code (including all REIT qualification tests). Thus, in applying the U.S. federal tax requirements described in this discussion, any corporations in which we own a 100% interest (other than any taxable REIT subsidiaries) 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 required to pay U.S. federal income tax, and our ownership of the stock of a qualified REIT subsidiary does not violate the restrictions on ownership of securities, as described below under “—Asset Tests.”

Ownership of Interests in Taxable REIT Subsidiaries . We own an interest in a number of taxable REIT subsidiaries 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. A taxable REIT subsidiary also includes any corporation other than a REIT with respect to which a taxable REIT subsidiary owns securities possessing more than 35% of the total voting power or value of the outstanding securities of such corporation. A taxable REIT subsidiary generally may engage in any business, including the provision of customary or non-customary services to tenants of its parent REIT, except that a taxable REIT subsidiary may not directly or indirectly operate or manage a lodging or healthcare facility or directly or indirectly provide to any other person (under a franchise, license or otherwise) rights to any brand name under which any lodging or healthcare facility is operated. A taxable REIT subsidiary is subject to U.S. 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 taxable REIT subsidiaries will not be subject to the 10% or 5% asset test described below. See “—Asset Tests.”

Income Tests . 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 entered into after July 30, 2008, and certain foreign currency gains recognized after July 30, 2008, from investments relating to real property or mortgages on real property, including “rents from real property” 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 entered into on or after January 1, 2005, and certain foreign currency gains recognized after July 30, 2008, from the real property investments described above or dividends, interest and gain from the sale or disposition of stock or securities, or from any combination of the foregoing. For these purposes, the term “interest” generally does not include any amount received or accrued,

Table of Contents

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:


•	The amount of rent must not be based in any way on the income or profits of any person. However, an amount we receive or accrue generally will not be excluded from the term “rents from real property” solely because it is based on a fixed percentage or percentages of receipts or sales;

We, or an actual or constructive owner of 10% or more of our common stock, must not actually or constructively own 10% or more of the interests in the assets or net profits of a non-corporate tenant, or, if the tenant is a corporation, 10% or more of the voting power or value of all classes of stock of the tenant. Rents received from such a tenant that is a taxable REIT subsidiary of ours, however, will not be excluded from the definition of “rents from real property” as a result of this condition if (1) at least 90% of the space at the property to which the rents relate is leased to third parties, and the rents paid by the taxable REIT subsidiary are substantially comparable to rents paid by our other tenants for comparable space or (2) the property to which the rents relate is a “qualified lodging facility” or “qualified health care property” and such property is operated on behalf of the taxable REIT subsidiary by an “eligible independent contractor” and certain other requirements are met. Whether rents paid by a taxable REIT subsidiary are substantially comparable to rents paid by other tenants of its parent REIT is determined at the time the lease with the taxable REIT subsidiary is entered into, extended, and modified, if such modification increases the rents due under such lease. Notwithstanding the foregoing, however, if a lease with a “controlled taxable REIT subsidiary” is modified and such modification results in an increase in the rents payable by such taxable REIT subsidiary, any such increase will not qualify as “rents from real property.” For purposes of this rule, a “controlled taxable REIT subsidiary” is a taxable REIT subsidiary in which we own stock possessing more than 50% of the voting power or more than 50% of the total value of the outstanding stock of such taxable REIT subsidiary;


•	Rent attributable to personal property, leased in connection with a lease of real property, is not greater than 15% of the total rent received under the lease. If this condition is not met, then the portion of the rent attributable to personal property will not qualify as “rents from real property”; and

•

We generally must not operate or manage the property or furnish or render services to our tenants, subject to a 1% de minimis exception and except as provided below. We may, however, perform services that are “usually or customarily rendered” in connection with the rental of space for occupancy only and are not otherwise considered “rendered to the occupant” of the property. Examples of these services include the provision of light, heat, or other utilities, trash removal and general maintenance of common areas. In addition, we may employ an independent contractor from whom we derive no revenue to provide customary services, or a taxable REIT subsidiary, which may be wholly or partially owned by us, to provide both customary and non-customary services to our tenants without causing the rent we receive from those tenants to fail to qualify as “rents from real property.”

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. Notwithstanding the foregoing, we may take actions which fail to satisfy one or more of the above conditions to the extent that we determine, based on the advice of our tax counsel, that those actions 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.

We sold the Plaza Las Fuentes Westin in 2011. Prior to its disposition, the Plaza Las Fuentes Westin had been leased by us to a wholly-owned subsidiary of a taxable REIT subsidiary of ours. For all periods during which we owned the property, we believe the Plaza Las Fuentes Westin constituted a “qualified lodging facility” that was operated on behalf of the taxable REIT subsidiary tenant by an “eligible independent contractor” from whom we did not derive any income. Thus, we believe that the rents we derived with respect to the Plaza Las Fuentes Westin lease qualified as rents from real property pursuant to the rules described above.

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 REIT 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 REIT 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 95% gross income test to the extent such a hedging transaction is entered into on or after January 1, 2005, and will not constitute gross income and thus will be exempt from the 75% gross income test to the extent such hedging transaction is entered into after July 30, 2008. Income and gain from a hedging transaction, including gain from the sale or disposition of such a transaction, entered into on or prior to July 30, 2008 will be treated as nonqualifying income for purposes of the 75% gross income test. Income and gain from a hedging transaction, including gain from the sale or disposition of such a transaction, entered into prior to January 1, 2005 will be qualifying income for purposes of the 95% gross income test. 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) for hedging transactions entered into after July 30, 2008, 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, we hedge other risks 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 REIT income tests. While we expect these actions will prevent a violation of the REIT 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. Commencing with our taxable year beginning January 1, 2005, we generally may make use of the relief provisions if:


•	following our identification of the failure to meet the 75% or 95% gross income tests for any taxable year, we file a schedule with the IRS setting forth each item of our gross income for purposes of the 75% or 95% gross income tests for such taxable year in accordance with Treasury Regulations to be issued; and

Table of Contents


•	our failure to meet these tests was due to reasonable cause and not due to willful neglect.

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 the 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 “—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 (including any net foreign currency gain recognized after July 30, 2008) 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. 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. Except as provided below, we do not intend to permit our operating partnership to enter into any sales that are prohibited transactions or that would require us to pay the 100% penalty tax. 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. From time to time, we acquire certain properties that we do not intend to hold for investment purposes through a taxable REIT subsidiary which is not subject to the 100% penalty tax on prohibited transactions. Any gain recognized by the taxable REIT subsidiary upon the sale of such property, and any income earned by the taxable REIT subsidiary while it operated such property before such sale, would be subject to regular federal corporate taxation.

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 one of our taxable REIT subsidiaries where the taxable REIT subsidiary is inadequately compensated, and redetermined deductions and excess interest represent any amounts that are deducted by a taxable REIT subsidiary 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.

From time to time our taxable REIT subsidiaries may provide services to our tenants. We intend to set any fees paid to our taxable REIT subsidiaries for such services at arm’s-length rates, although the fees paid may not satisfy the safe-harbor provisions described above. We also believe that the rent paid by the subsidiary of our taxable REIT subsidiary to our operating partnership pursuant to the Plaza Las Fuentes Westin lease reflects an arm’s-length charge. 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 any excess rents paid to us by our taxable REIT subsidiary.

Asset Tests. At the close of each calendar quarter of our taxable year, we must also satisfy four 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 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.

Table of Contents

Second, not more than 25% of the value of our total assets may be represented by securities (including securities of one or more 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, commencing with our taxable year beginning January 1, 2005, 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.

Fourth, not more than 25% (20% for taxable years ending on or before December 31, 2008) of the value of our total assets may be represented by the securities of one or more taxable REIT subsidiaries.

Our operating partnership owns, directly and indirectly, the stock of certain corporations that have elected, together with us, to be treated as our taxable REIT subsidiaries. So long as each of these companies qualifies as a 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 indirect ownership of such company’s stock. We may acquire securities in additional taxable REIT subsidiaries in the future. We believe that the aggregate value of our taxable REIT subsidiaries has not exceeded 20% of the aggregate value of our gross assets in any taxable year ending on or before December 31, 2008 and 25% of the aggregate value of our gross assets at times thereafter. 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. 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 (including, for our taxable year beginning on January 1, 2009 and all taxable years thereafter, a change caused by changes in the foreign currency exchange rate used to value any foreign assets we might own). 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 intend to maintain adequate records of the value of our assets to ensure compliance with the asset tests. If we failed 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% REIT asset tests if the value of our nonqualifying assets (1) 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 (2) 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

Table of Contents

after the 30-day cure period by taking steps including (1) the disposition of sufficient nonqualifying assets, or the taking of other actions, which allow us to meet the asset test 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, (2) 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 (3) 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 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.

Annual Distribution Requirements. 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:


•	90% of our “REIT taxable income”; and


•	90% of our after-tax net income, if any, from foreclosure property; minus


•	the excess of the sum of certain items of non-cash income over 5% of our “REIT taxable income.”

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, if we dispose of any asset we acquired from a corporation which is or has been a C corporation in a transaction in which our basis in the asset is determined by reference to the basis of the asset in the hands of that C corporation, within the ten-year period following our acquisition of such asset, we would be required to distribute at least 90% of the after-tax gain, if any, we recognized on the disposition of the asset, to the extent that gain does not exceed the excess of (1) the fair market value of the asset, over (2) our adjusted basis in the asset, in each case, on the date we acquired the 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 taxable to our stockholders, other than tax-exempt entities, 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. 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 otherwise 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 we have made, and 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 have not generated positive taxable income in the past several taxable years, and we currently do not expect to generate positive taxable income in the current taxable year. Accordingly, we did not pay distributions to our stockholders in 2011 , and we do not anticipate being required to pay distributions with respect to the current

Table of Contents

taxable year to satisfy the distribution requirements.

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 nondeductible 4% excise tax to the extent we fail to distribute during each calendar year at least the sum of 85% of our REIT 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 requirements 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.

Like-Kind Exchanges. Our operating partnership 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 U.S. federal income tax purposes. The failure of any such transaction to qualify as a like-kind exchange could subject us to U.S. federal income tax, possibly including the 100% prohibited transaction tax, depending on the facts and circumstances surrounding the particular transaction.

Failure to Qualify

Commencing with our taxable year beginning January 1, 2006, specified cure provisions are available to us in the event that we discover a violation of a provision of the Code that would result in our failure to qualify as a REIT. Except with respect to violations of the REIT income tests and assets 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 qualify 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 tax 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 this event, corporate distributees may be eligible for the dividends-received deduction. In addition, individuals may be eligible for the preferential rates on qualified dividend income (applicable through 2012, unless extended by Congress). Unless entitled to relief under specific statutory provisions, we will also be ineligible to elect to be treated as a REIT for the four taxable years following the year during which we lost 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 expect will be treated as partnerships or disregarded entities for U.S. federal income tax purposes. In general, entities that are classified as partnerships or disregarded entities for U.S. federal income tax purposes are “pass-through” entities which are not required to pay federal income tax. Rather, partners or members

Table of Contents

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 generally 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 REIT income tests and in the computation of our REIT taxable income and for purposes of the REIT distribution requirements. Moreover, for purposes of the REIT asset tests, we will include our pro rata share of assets held by our operating partnership, including our share of its subsidiary partnerships and limited liability companies, based on our capital interests in each such entity. See “—Taxation of Our Company—Ownership of Interests in Partnerships, Limited Liability Companies and Qualified REIT Subsidiaries.”

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 classified as a partnership for U.S. 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 which 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, 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 distributions. We believe our operating partnership and each of our other partnerships and limited liability companies will be classified as partnerships or disregarded entities for federal income tax purposes.

Allocations of Income, Gain, Loss and Deduction. The operating partnership agreement generally provides that items of operating income will be allocated to the holders of common units to the extent of cumulative net losses previously allocated to such common unit holders not previously offset by cumulative net income allocations, then to us to the extent of the accrued preferred return on our preferred units and then to the holders of common units in proportion to the number of common units held by each such unit holder. Items of operating loss will generally be allocated first to the holders of common units in proportion to the number of common units held until each such unit holder’s capital account is zero, and then to us. Certain limited partners have agreed to guarantee debt of our operating partnership, either directly or 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

Table of Contents

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 U.S. federal income tax purposes and do not affect the book capital accounts or other economic or legal arrangements among the partners.

Appreciated property was contributed to our operating partnership in exchange for interests in our operating partnership in connection with the formation transactions. The partnership agreement requires that these allocations 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. We and our operating partnership have agreed to use the “traditional method” for accounting for book-tax differences for the properties initially contributed to our operating partnership. Under the traditional method, which is the least favorable method from our perspective, the carryover basis of 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 all contributed properties were to have a tax basis equal to their 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 (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 “—Taxation of Our Company—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 will not apply.

Taxation of Holders of Our Common Stock

The following summary describes the material U.S. federal income tax consequences relating to the acquisition, ownership and disposition of our common stock. This summary deals only with our common stock held as a “capital asset” (generally, property held for investment within the meaning of Section 1221 of the Code). Your tax treatment will vary depending upon your particular situation.

This summary does not consider all of the rules which may affect the U.S. tax treatment of your investment in our common stock in light of your particular circumstances. For example, except to the extent discussed under the headings “—Taxation of Tax-Exempt Stockholders” and “—Taxation of Non-United States Holders,” special rules not discussed here may apply to you if you are:


•	financial institutions, banks and thrifts;


•	insurance companies;


•	tax-exempt organizations;


•	“S” corporations;


•	traders in securities that elect to mark to market;


•	partnerships, pass-through entities and persons holding our stock through a partnership or other pass-through entity;


•	stockholders subject to the alternative minimum tax;


•	regulated investment companies and REITs;

Table of Contents


•	foreign corporations or partnerships, and persons who are not residents or citizens of the U.S.;


•	broker-dealers or dealers in securities or currencies;


•	U.S. expatriates and certain former citizens or long-term residents of the U.S.;


•	persons holding our stock as part of a hedge, straddle, conversion, integrated or other risk reduction or constructive sale transaction; or


•	U.S. stockholders (as defined below) whose functional currency is not the U.S. dollar.

United States Holders

If you are a “U.S. holder,” as defined below, this section applies to you. Otherwise, the next section, “Non-United States Holders,” applies to you.

Definition of U.S. Holder. A “U.S. holder” is a beneficial holder of our common stock who, for U.S. federal income tax purposes, is:


•	an individual who is a citizen or resident of the U.S.;


•	a corporation, including an entity treated as a corporation for U.S. federal income tax purposes, created or organized in or under the laws of the U.S. or of any state thereof or in the District of Columbia;


•	an estate the income of which is subject to U.S. federal income taxation regardless of its source; or


•	a trust that (1) is subject to the primary supervision of a U.S. court and the control of one or more U.S. persons or (2) has a valid election in effect under applicable Treasury Regulations to be treated as a U.S. person.

If you hold shares of our common stock and are not a U.S. holder, a partnership or an entity classified as a partnership for U.S. federal income tax purposes, you are a “non-U.S. holder.”

If a partnership or other entity treated as a partnership for U.S. federal income tax purposes holds shares of our common 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 common stock are encouraged to consult their tax advisors.

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 that have previously been subject to corporate level tax discussed below, will be taxable to taxable U.S. holders 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. holders 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. holders, including individuals. For purposes of determining whether distributions to holders of our common stock are out of 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.

Table of Contents

To the extent that we make distributions on our common stock in excess of our current and accumulated earnings and profits, these distributions will be treated first as a tax-free return of capital to a U.S. holder. This treatment will reduce the U.S. holder’s adjusted tax basis in its shares of our common 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. holder’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. holders may not include in their own income tax returns any of our net operating losses or capital losses.

Capital Gain Dividends . Dividends that we properly designate as capital gain dividends will be taxable to our taxable U.S. holders 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. holders 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 stock for the year to the holders of our common stock and preferred 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 such 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 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 U.S. federal income tax purposes) would be adjusted accordingly, and a U.S. holder generally would:


•	include its pro rata share of our undistributed net capital gains in computing its long-term capital gains in its return for its taxable year in which the last day of our taxable year falls, subject to certain limitations as to the amount that is includable;


•	be deemed to have paid its share of the capital gains tax imposed on us on the designated amounts included in the U.S. holder’s long-term capital gains;


•	receive a credit or refund for the amount of tax deemed paid by it;


•	increase the adjusted basis of its common stock by the difference between the amount of includable gains and the tax deemed to have been paid by it; and


•	in the case of a U.S. holder that is a corporation, appropriately adjust its earnings and profits for the retained capital gains in accordance with Treasury Regulations to be promulgated by the IRS.

Passive Activity Losses and Investment Interest Limitations . Distributions made by us and gain arising from the sale or exchange by a U.S. holder of our shares will not be treated as passive activity income. As a result, U.S. holders generally will not be able to apply any “passive losses” against this income or gain. A U.S. holder may elect to treat capital gain dividends, capital gains from the disposition of stock and qualified dividend income 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 we make, 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.

Table of Contents

Dispositions of Our Common Stock . If a U.S. holder sells or disposes of shares of our common stock to a person other than us, it will recognize gain or loss for U.S. 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 for tax purposes. This gain or loss, except as provided below, will be long-term capital gain or loss if the holder has held the stock for more than one year at the time of such sale or disposition. If, however, a U.S. holder recognizes loss upon the sale or other disposition of our common 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. holder received distributions from us which were required to be treated as long-term capital gains.

Tax Rates. The maximum tax rate for non-corporate taxpayers for capital gains, including certain “capital gain dividends,” has generally been reduced to 15% (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). Capital gain dividends will only be eligible for the rates describe above to the extent they are properly designated by the REIT as “capital gain dividends.” The maximum tax rate for non-corporate taxpayers for income that the REIT properly designates as “qualified dividend income” has generally been reduced to 15%. 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 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 it distributed taxable income that it retained and paid tax on in the prior taxable year). The currently applicable provisions of the U.S. federal income tax laws relating to the 15% tax rate are currently scheduled to “sunset” or revert to the provisions of prior law effective for taxable years beginning after December 31, 2012 at which time the capital gains tax rate will be increased to 20% and the rate applicable to dividends will be increased to the tax rate then applicable to ordinary income. U.S. holders that are corporations may, however, be required to treat up to 20% of some capital gain dividends as ordinary income.

Medicare Tax on Unearned Income. Certain U.S. holders who 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 for taxable years beginning after December 31, 2012. U.S. holders should consult their tax advisors regarding the effect, if any, of this additional tax on their ownership and disposition of our common stock.

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

Information Reporting and Backup Withholding. We report to our U.S. holders 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 U.S. holder may be subject to backup withholding with respect to dividends paid unless the holder comes within certain 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. holder 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 U.S. holder’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 dividends to any U.S. holders who fail to certify their non-foreign status. See “—Taxation of Non-United States Holders.”

Taxation of Tax-Exempt Stockholders

Dividend income from us and gain arising upon a sale of our common stock generally should not be unrelated business taxable income to a tax-exempt stockholder, except as described below. This income or gain will be unrelated business taxable income, however, if a tax-exempt stockholder holds its shares as “debt-financed

Table of Contents

property” within the meaning of the Code or if the shares are used in a trade or business of the tax-exempt stockholder. 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 which are social clubs, voluntary employee benefit associations, supplemental unemployment benefit trusts, or qualified group legal services plans exempt from U.S. 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 common stock will constitute unrelated business taxable income 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 common stock. 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 limitations on the transfer and ownership of 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 in this paragraph should be inapplicable to our stockholders. However, because our stock is publicly traded, we cannot guarantee that this will always be the case.

Taxation of Non-United States Holders

The following discussion addresses the rules governing U.S. federal income taxation of the acquisition, ownership and disposition of our common stock by non-U.S. holders. 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 U.S. federal income taxation and does not address any state, local or foreign tax consequences that may be relevant to a non-U.S. holder in light of its particular circumstances. We urge non-U.S. holders to consult their tax advisors to determine the impact of federal, state, local and foreign income tax laws on the acquisition, ownership, and disposition of shares of our common stock, including any reporting requirements.

Distributions Generally . Distributions (including any taxable stock dividends) that are neither attributable to gain from our sale or exchange of U.S. real property interests 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 U.S. 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. holder 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 such a U.S. trade or business generally will not be subject to withholding but will be subject to U.S. federal income tax on a net basis at graduated rates, in the same manner as dividends paid to U.S. holders are subject to U.S. federal income tax. Any such dividends received by a non-U.S. holder that is a corporation may also be subject to an additional branch profits tax at a 30% rate (applicable after deducting U.S. federal income taxes paid on such effectively connected income) or such lower rate as may be specified by an applicable income tax treaty.

Distributions in excess of our current and accumulated earnings and profits will not be taxable to a non-U.S. holder to the extent that such distributions do not exceed the non-U.S. holder’s adjusted basis in our common stock, but rather will reduce the adjusted basis of such stock. To the extent that these distributions exceed a non-U.S. holder’s adjusted basis in our common stock, they will give rise to gain from the sale or exchange of such stock. The tax treatment of this gain is described below.

Table of Contents

For withholding purposes, we expect to treat all distributions as made out of our current or accumulated earnings and profits. As a result, except with respect to certain distributions attributable to the sale of U.S. real property interests described below, we expect to withhold U.S. income tax at the rate of 30% on any distributions made to a non-U.S. holder unless:


•	a lower treaty rate applies and the non-U.S. holder files with us an IRS Form W-8BEN evidencing eligibility for that reduced treaty rate; or


•	the non-U.S. holder files an IRS Form W-8ECI with us claiming that the distribution is income effectively connected with the non-U.S. holder’s trade or business.

However, amounts withheld should generally 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 United States Real Property Interests . Distributions to a non-U.S. holder that we properly designate as capital gain dividends, other than those arising from the disposition of a U.S. real property interest, generally should not be subject to U.S. federal income taxation, unless:


(1)	the investment in our common stock is treated as effectively connected with the non-U.S. holder’s U.S. trade or business, in which case the non-U.S. holder will be subject to the same treatment as U.S. holders with respect to such gain, except that a non-U.S. holder that is a foreign corporation may also be subject to the 30% branch profits tax, as discussed above; or


(2)	the non-U.S. holder is a nonresident alien individual who is present in the U.S. for 183 days or more during the taxable year and certain other conditions are met, in which case the nonresident alien individual will be subject to a 30% tax on the individual’s capital gains.

Pursuant to the Foreign Investment in Real Property Tax Act of 1980, which is referred to as “FIRPTA,” distributions to a non-U.S. holder that are attributable to gain from our sale or exchange of U.S. real property interests (whether or not designated as capital gain dividends) will cause the non-U.S. holder to be treated as recognizing such gain as income effectively connected with a U.S. trade or business. Non-U.S. holders would generally be taxed at the same rates applicable to U.S. holders, subject to any applicable alternative minimum tax. We also will be required to withhold and to remit to the IRS 35% (or 15% to the extent provided in Treasury Regulations) of any distribution to a non-U.S. holder that is designated as a capital gain dividend, or, if greater, 35% (or 15% to the extent provided in Treasury Regulations) of a distribution to the non-U.S. holder that could have been designated as a capital gain dividend. The amount withheld is creditable against the non-U.S. holder’s U.S. federal income tax liability. However, any distribution with respect to any class of stock which is regularly traded on an established securities market located in the U.S. 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 generally will 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 designated by us as retained capital gains in respect of the common stock held by U.S. holders generally should be treated with respect to non-U.S. holders in the same manner as actual distributions by us of capital gain dividends. Under this approach, a non-U.S. holder would be able to offset as a credit against its U.S. federal income tax liability resulting from its proportionate share of the tax paid by us on such retained capital gains, and to receive from the IRS a refund to the extent its proportionate share of such tax paid by us exceeds its actual U.S. federal income tax liability.

Table of Contents

Sale of Our Common Stock . Gain recognized by a non-U.S. holder upon the sale, exchange or other taxable disposition of our common stock generally will not be subject to U.S. taxation unless such stock constitutes a U.S. real property interest within the meaning of FIRPTA. Our common stock will not constitute a U.S. real property interest 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. holders. We believe, but cannot guarantee, that we have been a domestically-controlled qualified investment entity. In addition, because our common stock is publicly traded, no assurance can be given that we will continue to be a domestically-controlled qualified investment entity.

Notwithstanding the foregoing, gain from the sale, exchange or other taxable disposition of our common stock not otherwise subject to FIRPTA will be taxable to a non-U.S. holder if either (1) the investment in our common stock is treated as effectively connected with the non-U.S. holder’s U.S. trade or business or (2) the non-U.S. holder is a nonresident alien individual who is present in the U.S. for 183 days or more during the taxable year and certain other conditions are met. In addition, in general, even if we are a domestically controlled qualified investment entity, upon disposition of our common stock (subject to the 5% exception applicable to “regularly traded” stock described below), a non-U.S. holder may be treated as having gain from the sale, exchange or other taxable disposition of U.S. real property interest if the non-U.S. holder (or certain of its affiliate or related parties) (1) disposes of our common 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 U.S. real property interest and (2) acquires, or enters into a contract or option to acquire, or is deemed to acquire, other shares of our common stock during the 61-day period beginning with the first day of the 30-day period described in clause (1). The preceding sentence shall not apply to a non-U.S. holder if the non-U.S. did not own more than 5% of our common stock at any time during the one-year period ending on the date of the distribution described in clause (1) of the preceding sentence and our common stock is “regularly traded,” as defined by applicable Treasury Regulations. Non-U.S. holders should contact their tax advisors regarding the tax consequences of any sale, exchange, or other taxable disposition of our common stock.

Even if we do not qualify as a “domestically-controlled qualified investment entity” at the time a non-U.S. holder sells or exchanges our common stock, gain arising from such a sale or exchange would not be subject to U.S. federal income taxation under FIRPTA as a sale of a “U.S. real property interest” if:


(1)	our common stock is “regularly traded,” as defined by applicable Treasury regulations, on an established securities market such as the New York Stock Exchange; and


(2)	such non-U.S. holder owned, actually and constructively, 5% or less of our common stock throughout the five-year period ending on the date of such sale or exchange.

If gain on the sale or exchange of our common stock were subject to taxation under FIRPTA, the non-U.S. holder would be subject to regular U.S. federal income tax with respect to such gain in the same manner as a taxable U.S. holder (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 common stock were subject to taxation under FIRPTA, and if shares of such common stock were not “regularly traded” on an established securities market, the purchaser of such stock would be required to withhold and remit to the IRS 10% of the purchase price.

Foreign Accounts. Withholding taxes may apply to certain types of payments made to “foreign financial institutions” (as specially defined in the Code) and certain other passive non-U.S. entities. The failure to comply with additional certification, information reporting and other specified requirements could result in a withholding tax being imposed on payments of dividends and sales proceeds to foreign intermediaries and certain passive non-U.S. holders. A 30% withholding tax may be imposed on dividends on, and gross proceeds from the sale or other disposition of, our common stock paid to a foreign financial institution or to a non-financial foreign entity, unless (1) the foreign financial institution undertakes certain diligence and reporting, (2) the non-financial foreign entity

Table of Contents

either certifies it does not have any substantial U.S. owners or furnishes identifying information regarding each substantial U.S. 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. Treasury requiring, among other things, that it undertake to identify accounts held by certain U.S. persons or U.S.-owned foreign entities, annually report certain information about such accounts, and withhold 30% on payments to non-compliant foreign financial institutions and certain other account holders.

Although these rules currently apply to applicable payments made after December 31, 2012, the IRS has issued Proposed Treasury Regulations providing that the withholding provisions described above will generally apply to payments of dividends made on or after January 1, 2014 and to payments of gross proceeds from a sale or other disposition of stock on or after January 1, 2015. The Proposed Treasury Regulations described above will not be effective until they are issued in their final form, and as of the date of this prospectus, it is not possible to determine whether the proposed regulations will be finalized in their current form or at all. You should consult your tax advisor regarding these withholding provisions.

Information Reporting and Backup Withholding . Generally, we must report annually to the IRS the amount of dividends paid to a non-U.S. holder, such holder’s name and address, and the amount of tax withheld, if any. A similar report is sent to the non-U.S. holder. 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. holder 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 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. holder is a U.S. person.

Backup withholding is not an additional tax. Rather, the U.S. 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 furnished to the IRS.

Other Tax Consequences

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

MARKET PRICE OF AND DIVIDENDS ON COMMON EQUITY

AND RELATED STOCKHOLDER MATTERS

The information provided in Part II, Item 5 of our Annual Report on Form 10-K for the year ended December 31, 2011 , filed with the SEC on March 15, 2012 , is incorporated by reference herein.

Table of Contents

DESCRIPTION OF SECURITIES

The following summary of the material terms of the stock of our company in this section does not purport to be complete and is subject to and qualified in its entirety by reference to our charter and bylaws, copies of which we have previously filed with the SEC and which we incorporate by reference as exhibits to the registration statement of which this prospectus is a part. See “Where You Can Find More Information.”

General

Our charter provides that we may issue up to 100,000,000 shares of common stock, $0.01 par value per share, or common stock, and 50,000,000 shares of preferred stock, $0.01 par value per share, or preferred stock, 10,000,000 shares of which are classified as Series A cumulative redeemable preferred stock, or Series A preferred stock. Our charter authorizes our board of directors to amend our charter from time to time to increase or decrease the aggregate number of shares of stock or the number of shares of stock of any class or series that we have authority to issue without stockholder approval. As of March 9, 2012 , 50,753,644 shares of our common stock were issued and outstanding and 9,730,370 shares of Series A preferred stock were issued and outstanding. The 50,753,644 outstanding shares of our common stock excludes the 6,446,777 shares of common stock, as of March 9, 2012 , which we may issue in exchange for presently outstanding common units which may be tendered for redemption to our operating partnership.

Common Stock

All outstanding shares of our common stock are duly authorized, fully paid and nonassessable. Subject to the preferential rights of any other class or series of stock and to the provisions of our charter regarding the restrictions on transfer and ownership of stock, holders of shares of our common stock are entitled to receive dividends on such stock if, as and when authorized by our board of directors out of assets 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 of or adequate provision for all known debts and liabilities of our company.

Subject to the provisions of our charter regarding the restrictions on transfer and ownership of 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, except as provided with respect to any other class or series of stock, the holders of such shares will possess the exclusive voting power. There is no cumulative voting in the election of our board of directors, which means that the holders of a majority of the outstanding shares of our common stock can elect all of the directors then standing for election (except any Preferred Directors, as discussed in “—7.625% Series A Cumulative Redeemable Preferred Stock” below) and the holders of the remaining shares will not be able to elect any directors.

Holders of shares of our common stock have no preference, conversion, exchange, sinking fund or redemption rights, have no preemptive rights to subscribe for any securities of our company and generally have no appraisal rights unless our board of directors determines that appraisal rights apply, with respect to all or any classes or series of stock, to a particular transaction or transactions occurring after the date of such determination in connection with which stockholders would otherwise be entitled to exercise appraisal rights. Subject to the provisions of our charter regarding the restrictions on transfer of stock, 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, sell all or substantially all of its assets, engage in a share exchange or engage in similar transactions outside the ordinary course of business unless approved by the affirmative vote of stockholders holding at least two-thirds of the shares entitled to vote on the matter unless a lesser percentage (but not less than a majority of all of the votes entitled to be cast on the matter) is set forth in the corporation’s charter. Our charter does not provide for a lesser percentage in these situations. However, Maryland law permits a corporation to transfer all or substantially all of its assets

Table of Contents

without the approval of the stockholders of the corporation to one or more persons if all of the equity interests of the person or persons are owned, directly or indirectly, by the corporation. In addition, operating assets may be held by our subsidiaries and these subsidiaries may be able to transfer all or substantially all of such assets without a vote 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 classes of stock and to establish the number of shares in each class or series and to set the preferences, conversion and other rights, voting powers, restrictions, limitations as to dividends or other distributions, qualifications or terms or conditions of redemption for each such class or series.

Preferred Stock

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 any series. Prior to issuance of shares of each series, our board of directors is required by the MGCL and our charter to set the terms, preferences, conversion or other rights, voting powers, restrictions, limitations as to dividends or other distributions, qualifications and terms or conditions of redemption for each such series subject to the limited rights of holders of our Series A preferred stock and each parity class or series of preferred stock, voting together as a single class, to approve certain issuances of senior classes or series of stock. Thus, our board of directors could authorize the issuance of shares of preferred stock with terms and conditions which 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 stockholders or otherwise be in their best interest. Other than the Series A preferred stock, no shares of preferred stock are outstanding.

7.625% Series A Cumulative Redeemable Preferred Stock

General . Our board of directors and a duly authorized committee thereof approved articles supplementary, a copy of which we have previously filed with the SEC and which we incorporate by reference as an exhibit to the registration statement of which this prospectus is a part, creating the Series A preferred stock as a series of our preferred stock, designated as the 7.625% Series A Cumulative Redeemable Preferred Stock. The Series A preferred stock is validly issued, fully paid and nonassessable.

The Series A preferred stock is currently listed on the NYSE as “MPG Pr A.”

Ranking . The Series A preferred stock ranks, with respect to dividend rights and rights upon our liquidation, dissolution or winding-up:


•	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 Series A preferred stock;


•	on parity with any class or series of our stock expressly designated as ranking on parity with the Series A preferred stock; and


•	junior to any other class or series of our stock expressly designated as ranking senior to the Series A preferred stock.

Dividend Rate and Payment Date . Investors are entitled to receive cumulative cash dividends on the Series A preferred stock from and including the date of original issue, payable quarterly in arrears on or about the last calendar day of January, April, July and October of each year, at the rate of 7.625% per annum of the $25.00 liquidation preference per share. Dividends on the Series A preferred stock will accrue whether or not we have earnings, whether or not there are funds legally available for the payment of such dividends and whether or not such dividends are authorized or declared. From January 23, 2004 until October 31, 2008, we paid quarterly dividends on our Series A preferred stock at a rate of $0.4766 per share. On December 19, 2008, our board of directors suspended the payment of dividends on our Series A preferred stock. Dividends on our

Table of Contents

Series A preferred stock are cumulative and, therefore, will continue to accrue at an annual rate of $1.9064 per share. As of January 31, 2012 , we have missed 13 quarterly dividend payments totaling $60.3 million , which gives the holders of our Series A preferred stock the right to elect (voting together as a class with the holders of all other classes or series of parity preferred stock upon which like voting rights have been conferred and are exercisable) two additional members to our board of directors (the “Preferred Directors”). The holders of our Series A preferred stock will have the right to elect the Preferred Directors until all dividends in arrears and the then current period’s dividend have been fully paid, or until such dividends have been declared and an amount sufficient for the payment thereof has been set aside for payment, at which time the terms of the Preferred Directors will automatically terminate. On February 2, 2011, the holders of our Series A preferred stock elected two directors to our board of directors.

Liquidation Preference . If we liquidate, dissolve or wind-up, holders of the Series A preferred stock will have the right to receive $25.00 per share, plus accrued and unpaid dividends (whether or not earned or declared) up to and including the date of payment, before any payment is made to holders of our common stock and any other class or series of stock ranking junior to the Series A preferred stock as to liquidation rights. The rights of holders of Series A preferred stock to receive their liquidation preference will be subject to the proportionate rights of any other class or series of our stock ranking on parity with the Series A preferred stock as to liquidation.

Optional Redemption . Our Series A preferred stock is redeemable at our option, in whole or in part at any time or from time to time, for cash at a redemption price of $25.00 per share, plus accrued and unpaid dividends up to and including the redemption date. Any partial redemption will be on a pro rata basis.

No Maturity, Sinking Fund or Mandatory Redemption . The Series A preferred stock has no maturity date and we are not required to redeem the Series A preferred stock at any time. Accordingly, the Series A preferred stock will remain outstanding indefinitely, unless we decide, at our option, to exercise our redemption right. The Series A preferred stock is not subject to any sinking fund.

Voting Rights . Holders of Series A preferred stock generally have no voting rights. As of January 31, 2012 , however, we have missed 13 quarterly dividend payments, which gives the holders of our Series A preferred stock the right to elect (voting together as a class with the holders of all other classes or series of parity preferred stock upon which like voting rights have been conferred and are exercisable) the Preferred Directors. The holders of our Series A preferred stock will have the right to elect the Preferred Directors until all dividends in arrears and the then current period’s dividend have been fully paid, or until such dividends have been declared and an amount sufficient for the payment thereof has been set aside for payment, at which time the terms of the Preferred Directors will automatically terminate. In addition, we may not make certain material and adverse changes to the terms of the Series A preferred stock without the affirmative vote of the holders of at least two-thirds of the outstanding shares of Series A preferred stock and the holders of all other shares of any class or series ranking on parity with the Series A preferred stock that are entitled to similar voting rights (voting together as a single class).

Conversion . The Series A preferred stock is not convertible into or exchangeable for any of our other property or securities.

Power to Issue Additional Shares of Our Common Stock and Preferred Stock

Subject to the limited rights of holders of our Series A preferred stock and each parity class or series of preferred stock, voting together as a single class, to approve certain issuances of senior classes or series of stock, additional classes or series of stock, including the common stock, will be available for issuance without further action by our stockholders, unless stockholder consent 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. Our board of directors could authorize us to issue a class or series 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 stockholders or otherwise be in their best interest.

Restrictions on Transfer and Ownership

In order for us to qualify as a REIT under 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 our outstanding shares of stock may be owned, directly or indirectly, by five or fewer individuals (as defined in the Code to include certain entities such as qualified pension plans) 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 stock which 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 beneficially own, or be deemed to own by virtue of the applicable constructive ownership provisions of the Code, more than 9.8% (by value or by number of shares, whichever is more restrictive) of the outstanding shares of our common stock or more than 9.8% (by value or number of shares, whichever is more restrictive) of the outstanding shares of our Series A preferred stock. A person or entity that becomes subject to the ownership limit by virtue of a violative transfer that results in a transfer to a trust, as set forth below, is referred to as a “purported beneficial transferee” if, had the violative transfer been effective, the person or entity would have been a record owner and beneficial owner or solely a beneficial owner of our stock, or is referred to as a “purported record transferee” if, had the violative transfer been effective, the person or entity would have been solely a record owner of our stock.

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 shares of our stock by an individual or entity (or the acquisition of an interest in an entity that owns, actually or constructively, our stock) in amounts that do not exceed the ownership limit could, nevertheless, cause that individual or entity, or another individual or entity, to own constructively shares of our stock in excess of the ownership limit.

Our board of directors may, in its sole discretion, waive the ownership limit as it applies to our common stock with respect to a particular stockholder if it:


•	determines that such ownership will not cause any individual’s beneficial ownership of shares of our common stock to violate the ownership limit and that any exemption from the ownership limit will not jeopardize our status as a REIT; and

•

determines that such stockholder does not and will not own, actually or constructively, an interest in a tenant of ours (or a tenant of any entity owned in whole or in part by us) that would cause us to own, actually or constructively, more than a 9.8% interest (as set forth in Section 856(d)(2)(B) of the Code) in such tenant or that any such ownership would not cause us to fail to qualify as a REIT under the Code.

Our board of directors may also, in its sole discretion, waive the ownership limit as it applies to our Series A preferred stock with respect to a particular stockholder if it determines that such ownership will not jeopardize our status as a REIT. At no time since our inception has our board of directors granted such a waiver to any holder of our common or Series A preferred stock.

As a condition of our waiver of the ownership limit as it applies to any of our stock, our board of directors may require an opinion of counsel or IRS ruling satisfactory to our board of directors, and/or representations or undertakings from the applicant with respect to preserving our REIT status.

In connection with the waiver of the ownership limit as it applies to our stock or at any other time, our board of directors may decrease the ownership limit as it applies to our stock for all other persons and entities; provided, however, that the decreased ownership limit will not be effective for any person or entity whose

Table of Contents

percentage ownership in our stock is in excess of such decreased ownership limit until such time as such person or entity’s percentage of our stock, as applicable, equals or falls below the decreased ownership limit, but any further acquisition of our stock in excess of such percentage ownership will be in violation of the ownership limit. Additionally, the new ownership limit may not allow five or fewer stockholders to beneficially own more than 49% in value of our outstanding stock.

Our charter provisions further prohibit:


•	any person from beneficially or constructively owning shares of our stock that would result in us being “closely held” under Section 856(h) of the Code or otherwise cause us to fail to qualify as a REIT; and


•	any person from transferring shares of our stock if such transfer would result in shares of our stock being beneficially owned by fewer than 100 persons (determined without reference to any rules of attribution).

Any person who acquires or attempts or intends to acquire beneficial or constructive ownership of shares of our stock that will or may violate any of the foregoing restrictions on transferability and ownership will be required to give notice immediately to us 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 foregoing provisions on transferability and ownership will not apply if our board of directors determines that it is no longer in our best interests to attempt to qualify, or to continue to qualify, as a REIT or that compliance is no longer required for REIT qualification.

Pursuant to our charter documents, if any purported transfer of our stock or any other event would otherwise result in any person violating the ownership limit or such other limit as established by our board of directors or would result in us being “closely held” under Section 856(h) of the Code or otherwise failing to qualify as a REIT, then that number of shares in excess of the ownership limit or causing us to be “closely held” or otherwise to fail to qualify as a REIT (rounded up to the nearest whole) will be automatically transferred to, and held by, a trust for the exclusive benefit of one or more charitable organizations selected by us. 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 a transfer to the trust. Any dividend or other distribution paid to the purported record transferee, 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 for distribution to the beneficiary of the trust. 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” or otherwise failing to qualify as a REIT, then our charter documents provide that the transfer of the excess shares will be void. If any transfer would result in shares of our stock being beneficially owned by fewer than 100 persons, then any such purported transfer will be void and of no force or effect.

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 (i) the price paid by the purported record transferee for such shares (or, if the event which resulted in the transfer to the trust did not involve a purchase of such shares of our stock at market price, the last reported sales price reported on the NYSE on the trading day immediately preceding the day of the event which resulted in the transfer of such shares of our stock to the trust) and (ii) the market price on the date we, or our designee, accepts such offer. We have the right to accept such offer until the trustee has sold the shares of our stock held in the trust pursuant to the clauses discussed below. 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 purported record transferee and any dividends or other distributions held by the trustee with respect to such stock will be paid to the charitable beneficiary.

If we do not buy such shares, the trustee must, within 20 days of receiving notice from us of the transfer of shares to the trust, sell such shares to a person or entity designated by the trustee who could own such shares without violating the ownership limit or such other limit as established by our board of directors. After that, the trustee must distribute to the purported record transferee an amount equal to the lesser of (i) the price paid by the purported record transferee or owner for such shares (or, if the event which resulted in the transfer to the trust did

Table of Contents

not involve a purchase of such shares at market price, the last reported sales price reported on the NYSE on the trading day immediately preceding the relevant date) and (ii) the sales proceeds (net of commissions and other expenses of sale) received by the trust for such shares. The purported beneficial transferee or purported record transferee has no rights in the shares held by the trustee.

The trustee shall be designated by us and shall be unaffiliated with us and with any purported record transferee or purported beneficial transferee. Prior to the sale of any excess shares by the trust, the trustee will receive, in trust the beneficiary, all dividends and other distributions paid by us with respect to the excess shares, and may also exercise all voting rights with respect to the excess shares.

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


•	to rescind as void any vote cast by a purported record transferee prior to our discovery that the shares have been transferred to the trust; and


•	to recast the vote in accordance with the desires of the trustee acting for the benefit of the beneficiary of the trust.

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

Any beneficial owner or constructive owner of shares of our stock and any person or entity (including the stockholder of record) who is holding shares of our stock for a beneficial owner must, on request, provide us with a completed questionnaire containing the information regarding their ownership of such shares, as set forth in the applicable Treasury regulations. In addition, any person or entity that is a beneficial owner or constructive owner of shares of our stock and any person or entity (including the stockholder of record) who is holding shares of our stock for a beneficial owner or constructive owner shall, on request, be required to disclose to us in writing such information as we may request in order to determine the effect, if any, of such stockholder’s actual and constructive ownership of shares of our stock on our status as a REIT and to ensure compliance with the ownership limit, or as otherwise permitted by our board of directors.

All certificates representing shares of our stock bear a legend referring to the restrictions described above.

These ownership limits could delay, defer or prevent a transaction or a change of control of our company that might involve a premium price for our stockholders or otherwise be in their best interest.

EXCHANGE OF COMMON UNITS FOR COMMON STOCK

Terms of the Exchange

The holders of common units of our operating partnership who hold common units which may be redeemed for shares of our common stock are referred to as the “selling stockholders.” The selling stockholders hold an aggregate of 6,446,777 common units. The selling stockholders may require our operating partnership to redeem their common units by delivering to us, as general partner of our operating partnership, a notice of redemption. Upon receipt of the notice of redemption, we may, in our sole and absolute discretion, elect to redeem some or all of such common units for cash or, subject to the limitations on ownership and transfer of our common stock set forth in our charter, elect to exchange some or all of those common units for shares of our common stock on a one-for-one basis, subject to adjustment as described in the section entitled “Description of the Partnership Agreement of MPG Office, L.P.—Redemption/Exchange Rights.”

Once we receive a notice of redemption from a common limited partner, we will determine whether to redeem the tendering partner’s common units for cash or exchange some or all of the tendering partner’s common units for shares of our common stock. We will promptly notify the tendering partner if we decide to exchange the tendering partner’s common units for shares of our common stock. Any shares of our common stock that we issue will be duly authorized, validly issued, fully paid and nonassessable shares, free of any pledge, lien, encumbrance or restriction other than those provided in:


•	our charter;


•	our bylaws;


•	the Securities Act;


•	relevant state securities or blue sky laws; and


•	any applicable registration rights agreement with respect to the shares entered into by the tendering partner.

Each tendering partner will continue to own all common units subject to any redemption or exchange, and be treated as a limited partner with respect to the common units for all purposes, until the limited partner transfers the common units to us, is paid for them or receives shares of our common stock in exchange for them. Until that time, the limited partner will have no rights as one of our stockholders.

Conditions to the Exchange

We will issue shares of our common stock in exchange for common units to a tendering partner if each of the following conditions is satisfied or waived:


•	the exchange would not cause the tendering partner or any other person to violate the ownership limit set forth in our charter or any other provision of our charter;


•	the exchange is for at least 1,000 common units, or, if less than 1,000 common units, all of the common units held by the tendering partner;


•	the redemption is not effected during the period after the record date that we established for a distribution from our operating partnership to its partners and before the record date that we established for a distribution to our common stockholders; and


•	the consummation of any redemption or exchange will be subject to the expiration or termination of any applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended.

DESCRIPTION OF THE

PARTNERSHIP AGREEMENT OF MPG OFFICE, L.P.

We have summarized the material terms and provisions of the Second Amended and Restated Agreement of Limited Partnership of MPG Office, 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 as an exhibit to the registration statement of which this prospectus is part. For purposes of this section, references to “we,” “our,” “us” and “our company” refer to MPG Office Trust, Inc.

Management of Our Operating Partnership

Our operating partnership, MPG Office, L.P., is a Maryland limited partnership that was formed on June 26, 2002. We are the sole general partner of our operating partnership and conduct substantially all of our business in or through it. As sole general partner of our operating partnership, we exercise exclusive and complete responsibility and discretion in its day-to-day management and control. We can cause our operating partnership to enter into certain major transactions, including acquisitions, dispositions and refinancings, subject to certain limited exceptions. The limited partners of our operating partnership may not transact business for, or participate in the management activities or decisions of, our operating partnership, except as provided in the partnership agreement and as required by applicable law. Certain restrictions under the partnership agreement limit our ability to engage in a business combination as more fully described in “—Termination Transactions” below.

The limited partners of our operating partnership expressly acknowledged that we, as general partner of our operating partnership, are acting for the benefit of the operating partnership, the limited partners and our stockholders collectively. Our company is under no obligation to give priority to the separate interests of the limited partners or our stockholders in deciding whether to cause our operating partnership to take or decline to take any actions. If there is a conflict between the interests of our stockholders on one hand and the limited partners on the other, we will endeavor in good faith to resolve the conflict in a manner not adverse to either our stockholders or the limited partners; provided, however, that for so long as we own a controlling interest in our operating partnership, any conflict that cannot be resolved in a manner not adverse to either our stockholders or the limited partners shall be resolved in favor of our stockholders. We are not liable under the partnership agreement to our operating partnership or to any partner for monetary damages for losses sustained, liabilities incurred, or benefits not derived by limited partners in connection with such decisions; provided, that we have acted in good faith.

The partnership agreement provides that all our business activities, including all activities pertaining to the acquisition and operation of properties, must be conducted through our operating partnership, and that our operating partnership must be operated in a manner that will enable us to satisfy the requirements for being classified as a REIT.

Transferability of Interests

Except in connection with a transaction described in “—Termination Transactions” below, we, as general partner, may not voluntarily withdraw from our operating partnership, or transfer or assign all or any portion of our interest in our operating partnership, without the consent of a majority of the units held by limited partners (other than limited partners 50% or more of whose equity is owned, directly or indirectly, by us as general partner). Any transfer of common units by the limited partners, other than certain exceptions, will be subject to a right of first refusal by us and must be made only to “accredited investors” as defined under Rule 501 of the Securities Act.

Amendments of the Partnership Agreement

Amendments to the partnership agreement may be proposed by us, as general partner, or by limited partners owning at least 25% of the units held by limited partners.

Table of Contents

Generally, the partnership agreement may be amended, modified or terminated with the approval of partners holding 66-2/3% of all outstanding units (including the units held by us as general partner). As general partner, we will have the power to unilaterally make certain amendments to the partnership agreement without obtaining the consent of the limited partners as may be required to:


•	add to our obligations as general partner or surrender any right or power granted to us as general partner for the benefit of the limited partners;


•	reflect the issuance of additional units or the admission, substitution, termination or withdrawal of partners in accordance with the terms of the partnership agreement;


•	set forth or amend the designations, rights, powers, duties and preferences of holders of any additional units issued in accordance with the terms of the partnership agreement;

•

reflect a change of an inconsequential nature that does not adversely affect the limited partners in any material respect, or cure any ambiguity, correct or supplement any provisions of the partnership agreement not inconsistent with law or with other provisions of the partnership agreement, or make other changes concerning matters under the partnership agreement that will not otherwise be inconsistent with the partnership agreement or law;


•	satisfy any requirements, conditions or guidelines contained in any order, directive, opinion, ruling, regulation of a federal or state agency or contained in federal or state law;


•	reflect changes that are reasonably necessary for us, as general partner, to maintain our status as a REIT; or


•	modify the manner in which capital accounts are computed.

Amendments that would, among other things, convert a limited partner’s interest into a general partner’s interest, modify the limited liability of a limited partner, alter a partner’s right to receive any distributions or allocations of profits or losses or materially alter or modify the redemption rights described below must be approved by each limited partner that would be adversely affected by such amendment.

In addition, without the written consent of a majority of the units held by limited partners (other than limited partners 50% or more of whose equity is owned, directly or indirectly, by us as general partner), we, as general partner, may not do any of the following:


•	take any action in contravention of an express prohibition or limitation contained in the partnership agreement;


•	enter into or conduct any business other than in connection with our role as general partner of the operating partnership and our operation as a REIT;


•	acquire an interest in real or personal property other than through our operating partnership;


•	withdraw from the operating partnership or transfer any portion of our general partnership interest; or


•	be relieved of our obligations under the partnership agreement following any permitted transfer of our general partnership interest.

7.625% Series A Cumulative Redeemable Preferred Units

General. Our operating partnership has designated a class of preferred limited partnership units as the 7.625% Series A Cumulative Redeemable Preferred Units, or the Series A preferred units, representing preferred limited partnership interests in our operating partnership. As of the date of this prospectus, 9,730,370 Series A preferred units are issued and outstanding.

Distributions. Each Series A preferred unit is entitled to receive cumulative preferential cash distributions payable on the last calendar day of January, April, July and October of each year. Series A preferred units are entitled to distributions at a rate of 7.625% per annum. The cumulative preferential distributions are paid in preference to any payment made on any other class or series of partnership interest of our operating partnership, other than any other class or series of partnership interest expressly designated as ranking on parity with or senior to the Series A preferred units.

Ranking. With respect to distribution rights and rights upon voluntary or involuntary liquidation, winding-up or dissolution, the Series A preferred units rank:


•	senior to all classes or series of our common units and to any other class or series of preferred partnership units expressly designated as ranking junior to the Series A preferred units;


•	on parity with all other classes or series of preferred partnership units expressly designated as ranking on parity with the Series A preferred units; and


•	junior to any other class or series of preferred partnership units expressly designated as ranking senior to the Series A preferred units.

Redemption and exchange. We may redeem the Series A preferred units out at a redemption price equal to $25.00 per unit, plus accrued and unpaid distributions to the date of redemption. The Series A preferred units may not be exchanged for any other class or series of interest in the operating partnership.

Liquidation preference. The distribution and income allocation provisions of the partnership agreement have the effect of providing each Series A preferred unit with a liquidation preference to each holder equal to their capital contributions, plus any accrued but unpaid distributions, in preference to any other class or series of partnership interest.

Common Units

We discuss the rights and preferences of our common units in the section entitled “—Redemption/Exchange Rights.”

Redemption/Exchange Rights

Limited partners have the right to have all or part of their common units of our operating partnership redeemed at any time. At the time of redemption, we have the right to determine whether to redeem the common units for cash, based upon the fair market value of an equivalent number of shares of our common stock at the time of redemption, or exchange them for shares of our common stock on a one-for-one basis, subject to adjustment in the event of stock splits, stock dividends, issuance of stock rights, specified extraordinary distributions and similar events. We presently anticipate that we will elect to issue shares of our common stock in exchange for common units in connection with each redemption request, rather than having our operating partnership redeem the common units for cash. With each redemption or exchange, we increase our percentage ownership interest in our operating partnership. Limited partners may exercise this redemption right from time to time, in whole or in part, except when, as a consequence of shares of our common stock being issued, any person’s actual or constructive stock ownership would exceed our company’s ownership limit, or any other limit as provided in our charter or as

Table of Contents

otherwise determined by our board of directors as described under the section entitled “Description of Securities—Restrictions on Transfer.”

Issuance of Additional Common Units, Preferred Units, Common Stock, Preferred Stock or Convertible

Securities

As sole general partner, we have the ability to cause the operating partner to issue additional units representing general and limited partnership interests. These additional units may include preferred limited partnership units with terms, provisions and rights that are preferential to those of the common units. In addition, we may issue additional shares of our common stock, preferred stock or convertible securities, but only if we cause our operating partnership to issue to us partnership interests or rights, options, warrants or convertible or exchangeable securities of our operating partnership having designations, preferences and other rights, so that the economic interests of our operating partnership’s interests issued are substantially similar to the securities that we have issued.

Tax Matters

We are the tax matters partner of our operating partnership and, as such, we have authority to make tax elections under the Code on behalf of our operating partnership.

Allocations of Net Income or Losses to Partners

The net income of our operating partnership will generally be allocated to us to the extent of the accrued preferred return on our Series A preferred units and then to us, as general partner, and the limited partners in accordance with our respective common percentage interests in our operating partnership. Net loss will generally be allocated to us, as general partner, and the limited partners in accordance with our respective common percentage interests in our operating partnership until the limited partners’ capital is reduced to zero and any remaining net loss would be allocated to us. However, in some cases losses may be disproportionately allocated to partners who have guaranteed debt of our operating partnership. The allocations described above are subject to special allocations relating to depreciation deductions and to compliance with the provisions of Sections 704(b) and 704(c) of the Code and the associated Treasury regulations.

Operations

The partnership agreement provides that we, as general partner, will determine and distribute the net operating cash revenues of our operating partnership, as well as the net sales and refinancing proceeds, quarterly, pro rata in accordance with the partners’ percentage interests.

The partnership agreement provides that our operating partnership will assume and pay when due, or reimburse us for payment of, all costs and expenses relating to the operations of, or for the benefit of, our operating partnership.

Termination Transactions

The partnership agreement provides that our company may not engage in any merger, consolidation or other combination with or into another person, sale of all or substantially all of our assets or any reclassification or any recapitalization or change in outstanding shares of our common stock (a “termination transaction”), unless in connection with such termination transaction:


(i)	we obtain the consent of at least 50% of the partners of our operating partnership (including units held by our company), and


(ii)	either:

Table of Contents

(A) all limited partners will receive, or have the right to elect to receive, for each common unit an amount of cash, securities, or other property equal to the product of:


•	the number of shares of our common stock into which each common unit is then exchangeable, and

•

the greatest amount of cash, securities or other property paid to the holder of one share of our common stock in consideration of one share of our common stock pursuant to the termination transaction, provided that, if, in connection with such termination transaction, a purchase, tender or exchange offer is made to and accepted by the holders of more than 50% of the outstanding shares of our common stock, each holder of common units will receive, or will have the right to elect to receive, the greatest amount of cash, securities, or other property which such holder would have received had it exercised its redemption right and received shares of our common stock in exchange for its common units immediately prior to the expiration of such purchase, tender or exchange offer and accepted such purchase, tender or exchange offer; or

(B) the following conditions are met:


•	substantially all of the assets of the surviving entity are held directly or indirectly by our operating partnership or another limited partnership or limited liability company that is the surviving partnership of a merger, consolidation or combination of assets with our operating partnership;


•	the holders of units own a percentage interest of the surviving partnership based on the relative fair market value of the net assets of our operating partnership and the other net assets of the surviving partnership immediately prior to the consummation of such termination transaction;


•	the rights, preferences and privileges of such unit holders in the surviving partnership are at least as favorable as those in effect immediately prior to the consummation of such termination transaction and as those applicable to any other limited partners or non-managing members of the surviving partnership; and

•

the limited partners have the right to either (i) exchange their interests in the surviving partnership for either the consideration available to the common limited partners pursuant to paragraph ii(A) in this section, or (ii) exchange their units for cash on terms equivalent to those in effect with respect to their units immediately prior to the consummation of such transaction, or, if the ultimate controlling person of the surviving partnership has publicly traded common equity securities, shares of those common equity securities, at an exchange ratio based on the relative fair market value of those securities and our common stock.

Term

Our operating partnership will continue in full force and effect until December 31, 2102, or until sooner dissolved in accordance with its terms or as otherwise provided by law.

Indemnification and Limitation of Liability

To the extent permitted by applicable law, the partnership agreement indemnifies us, as general partner, and our officers, directors, employees, agents and any other persons we may designate from and against any and all claims arising from operations of our operating partnership in which any indemnitee may be involved, or is

Table of Contents

threatened to be involved, as a party or otherwise, unless it is established that:


•	the act or omission of the indemnitee was material to the matter giving rise to the proceeding and either was committed in bad faith or fraud, or was the result of active and deliberate dishonesty;


•	the indemnitee actually received an improper personal benefit in money, property or services; or


•	in the case of any criminal proceeding, the indemnitee had reasonable cause to believe that the act or omission was unlawful.

Similarly, we, as general partner of our operating partnership, and our officers, directors, agents or employees, are not liable or accountable to our operating partnership for losses sustained, liabilities incurred or benefits not derived as a result of errors in judgment or mistakes of fact or law or any act or omission so long as we acted in good faith.

MATERIAL PROVISIONS OF MARYLAND LAW AND OF OUR CHARTER AND BYLAWS

The following summary of certain provisions of Maryland law and of 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 we have previously filed with the SEC and which we incorporate by reference as exhibits to the registration statement of which this prospectus is a part. See “Where You Can Find More Information.”

Our Board of Directors

Our bylaws provide that the number of directors of our company may be established by our board of directors but may not be fewer than the minimum number permitted under the MGCL or more than 15. Any vacancy will be filled, at any regular meeting or at any special meeting called for that purpose, by a majority of the remaining directors.

Except for any Preferred Directors, as discussed below, each of our directors is elected by our common stockholders to serve until the next annual meeting and until their successors are duly elected and qualify. Holders of shares of our common stock will have no right to cumulative voting in the election of directors. Consequently, at each annual meeting of stockholders, the holders of a majority of the shares of our common stock will be able to elect all of our directors (other than any Preferred Directors). Additionally, as of January 31, 2012 we have missed 13 quarterly dividend payments, which gives the holders of our Series A preferred stock the right to elect (voting together as a class with the holders of all other classes or series of parity preferred stock upon which like voting rights have been conferred and are exercisable) two additional members to our board of directors. On February 2, 2011, holders of the Series A preferred stock elected two directors to our board of directors. See “Description of Securities—7.625% Series A Cumulative Redeemable Preferred Stock.”

Removal of Directors

Our charter provides that a director may be removed only for cause (as defined in our charter) and only by the affirmative vote of stockholders entitled to cast at least two-thirds of the votes entitled to be cast generally in the election of directors. This provision, when coupled with the provision in our bylaws authorizing our board of directors to fill vacant directorships, precludes stockholders from removing incumbent directors except upon the existence of cause for removal and a substantial affirmative vote 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 A preferred stock may only be removed by a vote of such Series A preferred stockholders.

Business Combinations

Under the MGCL, certain “business combinations” (including a merger, consolidation, share exchange or, in certain circumstances, an asset transfer or issuance or reclassification of equity securities) between a Maryland corporation and an interested stockholder— i.e. , any person who beneficially owns 10% or more of the voting power of the corporation’s outstanding voting stock or an affiliate or associate of the corporation who, at any time within the two-year period prior to the date in question, was the beneficial owner of 10% or more of the voting power of the then outstanding stock of the corporation—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. Thereafter, any such business combination must be recommended by the board of directors of such corporation and approved by the affirmative vote of at least (a) 80% of the votes entitled to be cast by holders of outstanding shares of the voting stock of the corporation and (b) two-thirds of the votes entitled to be cast by holders of the voting stock of the corporation other than shares held by the interested stockholder with whom (or with whose affiliate) the business combination is to be effected or held by an affiliate or associate of the interested stockholder, unless, 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. A person is not an interested stockholder under the statute if the board of

Table of Contents

directors approved in advance the transaction by which the person otherwise would have become an interested stockholder. Our board of directors may provide that its approval is subject to compliance with any terms and conditions determined by it.

However, these provisions of the MGCL do not apply to business combinations that are approved or exempted by a 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 opted out of these 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 person. As a result, any person may be able to enter into business combinations with us that may not be in the best interest of our stockholders without compliance by our company with the super-majority vote requirements and the other provisions of the statute. There can be no assurance that our board of directors will not opt to be subject to such business combination provisions in the future.

Control Share Acquisitions

The MGCL provides that “control shares” of a Maryland corporation acquired in a “control share acquisition” have no voting rights except to the extent approved at a special meeting by the affirmative vote of two-thirds of the votes entitled to be cast on the matter, excluding shares of stock in a corporation in respect of which any of the following persons is entitled to exercise or direct the exercise of the voting power of shares of stock of the corporation in the election of directors: (i) a person who makes or proposes to make a control share acquisition, (ii) an officer of the corporation or (iii) an employee of the corporation who is also a director of the corporation. “Control shares” are voting shares of stock which, if aggregated with all other such shares of stock previously acquired by the acquiror or in respect of which the acquiror is able to exercise or direct the exercise of voting power (except solely by virtue of a revocable proxy), would entitle the acquiror to exercise voting power in electing directors within one of the following ranges of voting power: (i) one-tenth or more but less than one-third, (ii) one-third or more but less than a majority, or (iii) a majority or more of all voting power. Control shares do not include shares the acquiring person is then entitled to vote as a result of having previously obtained stockholder approval. A “control share acquisition” means the acquisition of 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), may compel our 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 shares. If no request for a meeting is made, the corporation may itself present the question at any stockholders’ meeting.

If voting rights 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 acquiror 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 acquiror 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 acquiror in the control share acquisition.

The control share acquisition statute does not apply (a) to shares acquired in a merger, consolidation or share exchange if the corporation is a party to the transaction or (b) 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 acquisitions by any person of our stock. There can be no assurance that such provision will not be amended or eliminated at any time in the future.

Subtitle 8

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 five provisions:


•	a classified board of directors;


•	a two-thirds vote requirement for removing a director;


•	a requirement that the number of directors be fixed only by vote of the directors;


•	a requirement that a vacancy on the board of directors be filled only by the remaining directors and for the remainder of the full term of the class of directors in which the vacancy occurred; and


•	a majority requirement for the calling of a special meeting of stockholders.

Through provisions in our charter and bylaws unrelated to Subtitle 8, we already (a) require a two-thirds vote for the removal of any director from our board of directors, (b) vest in our board of directors the exclusive power to fix the number of directorships and (c) 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 a majority of the votes entitled to be cast to call a special meeting.

Amendment to Our Charter

Generally, our charter, including its provisions on removal of directors, 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 not less than two-thirds of all of the votes entitled to be cast on the matter and, in the case of an amendment that would materially and adversely affect the terms of our Series A preferred stock, the affirmative vote or consent of the holders of two-thirds of the outstanding shares of our Series A preferred stock voting as a single class.

Transactions Outside the Ordinary Course of Business

Generally, we may not merge with or into another company, sell all or substantially all of our assets, engage in a share exchange or engage in similar transactions outside the ordinary course of business unless such transaction is declared advisable by our board of directors and approved by the affirmative vote of stockholders entitled to cast not less than two-thirds of all of the votes entitled to be cast on the matter and, in the case of any such transaction in which our charter would be amended to materially and adversely affect the terms of our Series A preferred stock, the affirmative vote or consent of the holders of two-thirds of the outstanding shares our Series A preferred stock voting as a single class.

Dissolution of Our Company

The dissolution of our company must be declared advisable by a majority of our entire board of directors and approved by the affirmative vote of stockholders entitled to cast not less than two-thirds of all of the votes entitled to be cast on the matter.

Table of Contents

Advance Notice of Director Nominations and New Business

Our bylaws provide that:


•	with respect to an annual meeting of stockholders, nominations of persons for election to our board of directors and the proposal of business to be considered by stockholders may be made only:


•	pursuant to our notice of the meeting;


•	by or at the direction of our board of directors; or


•	by a stockholder who is a stockholder of record both at the time of giving the notice required by our bylaws and at the time of the meeting, who is entitled to vote at the meeting and who has complied with the advance notice procedures set forth in our bylaws.


•	with respect to special meetings of stockholders, only the business specified in our company’s notice of meeting may be brought before the meeting of stockholders and nominations of persons for election to our board of directors may be made only:


•	pursuant to our notice of the meeting;


•	by or at the direction of our board of directors; or


•	provided that our board of directors has determined that directors shall be elected at such meeting, by a stockholder who is a stockholder of record both at the time of giving the notice required by our bylaws and at the time of the meeting, who is entitled to vote at the meeting and who has complied with the advance notice provisions set forth in our bylaws.

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

The provisions of our charter on removal of directors 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 stockholders or otherwise be in their best interest. Likewise, if our company’s board of directors were to opt in to the business combination provisions of the MGCL or the classified board provision of Subtitle 8 or if the provision in our bylaws opting out of the control share acquisition provisions of the MGCL were rescinded, these provisions of the MGCL could have similar anti-takeover effects.

Ownership Limit

Our charter, including the articles supplementary creating the Series A preferred stock, copies of which we have previously filed with the SEC and which we incorporate by reference as exhibits to the registration statement of which this prospectus is a part, provide 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% (by value or by number of shares, whichever is more restrictive) of the outstanding shares of our common stock or more than 9.8% (by value or by number of shares, whichever is more restrictive) of the outstanding shares of our Series A preferred stock. We refer to this restriction as the “ownership limit.” For a fuller description of this restriction and the constructive ownership rules, see “Description of Securities—Restrictions on Transfer” and our charter and the articles supplementary creating the Series A preferred stock.

Indemnification and Limitation of Directors’ and Officers’ Liability

The MGCL 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 established by a final judgment as being material to the cause of action. Our charter contains such a provision which eliminates such liability to the maximum extent permitted by Maryland law.

The MGCL requires a corporation (unless its charter provides otherwise, which our company’s 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 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:


•	the act or omission of the director or officer was material to the matter giving rise to the proceeding and:


•	was committed in bad faith; or


•	was the result of active and deliberate dishonesty; or


•	the director or officer actually received an improper personal benefit in money, property or services; or


•	in the case of any criminal proceeding, the director or officer had reasonable cause to believe that the act or omission was unlawful.

However, under the MGCL, a Maryland corporation may not indemnify for an adverse judgment in a suit by or in the right of the corporation or for a judgment of liability 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 corporation to advance reasonable expenses to a director or officer upon the corporation’s receipt of:


•	a written affirmation by the director or officer of his or her good faith belief that he or she has met the standard of conduct necessary for indemnification by the corporation; and


•	a written undertaking by the director or on the director’s behalf to repay the amount paid or reimbursed by the corporation if it is ultimately determined that the director did not meet the standard of conduct.

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, without requiring a preliminary determination of the ultimate entitlement to indemnification, pay or reimburse reasonable expenses in advance of final disposition of a proceeding to:


•	any present or former director or officer who is made or threatened to be made a party to the proceeding by reason of his or her service in that capacity; or

•

any individual who, while a director of our company and at our request, serves or has served another corporation, REIT, partnership, joint venture, trust, employee benefit plan or any other enterprise as a director, officer, partner or trustee of such corporation, REIT, partnership, joint venture, trust, employee benefit plan or other enterprise and who is made or threatened to be made a party to the proceeding by reason of his or her service in that capacity.

Table of Contents

Our charter and bylaws also permit us 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.

Additionally, we have entered into indemnification agreements with our directors and executive officers, as permitted under Maryland law.

The partnership agreement provides that we, as general partner, and our officers and directors are indemnified to the fullest extent permitted by law. See “Description of the Partnership Agreement of MPG Office, L.P.—Indemnification and Limitation of Liability.”

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers or persons controlling the registrant pursuant to the foregoing provisions, we have been informed that in the opinion of the SEC such indemnification is against public policy as expressed in the Act and is therefore unenforceable.

Item 33.	Recent Sales of Unregistered Securities.

During the fiscal year ended December 31, 2011, the Company entered into agreements providing for the exchange of shares of its Series A preferred stock for shares of its common stock. Details of the exchanges are as follows:



	Series A Preferred Stock Exchanged	Common Stock Issued	Exchange Ratio (Common Shares Issued per Preferred Share)	Series A Preferred Stock Value per Share		Common Stock Value per Share
July 25, 2011 exchange	218,635	1,127,597	5.157	$	19.00	$	3.684
July 27, 2011 exchange	50,995	262,981	5.157	16.50		3.200

In connection with the exchanges, during 2011 we recorded a $2.8 million preferred stock redemption discount in our consolidated statement of operations that is added to our net income available to common stockholders for use in the calculation of earnings per share. The preferred stock redemption discount represents the excess of the carrying amount of our Series A preferred stock, including cumulative dividends not declared, over the fair value of the consideration transferred to the holders of our Series A preferred stock at the time of exchange. The shares of common stock issued in the exchanges were exchanged by the Company with existing stockholders and were exchanged in reliance on the exemption from registration provided in Section 3(a)(9) of the Securities Act, as amended, and corresponding provisions of state securities laws. No commission or other remuneration was paid or given directly or indirectly for soliciting such exchanges.

Item 37. Undertakings.

The undersigned registrant hereby undertakes:


1.	To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:


i.	To include any prospectus required by Section 10(a)(3) of the Securities Act;

ii.

To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement.


iii.	To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;


2.	That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.


3.	To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

That, for the purpose of determining liability of the registrant under the Securities Act to any purchaser in the initial distribution of the securities: The undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:


i.	Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;


ii.	Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;


iii.	The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and


iv.	Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

The undersigned registrant hereby further undertakes to deliver or cause to be delivered with the prospectus, to each person to whom the prospectus is sent or given, the latest annual report to security holders that

II- 11

Table of Contents

is incorporated by reference in the prospectus and furnished pursuant to and meeting the requirements of Rule 14a-3 or Rule 14c-3 under the Exchange Act; and, where interim financial information required to be presented by Article 3 of Regulation S-X are not set forth in the prospectus, to deliver, or cause to be delivered to each person to whom the prospectus is sent or given, the latest quarterly report that is specifically incorporated by reference in the prospectus to provide such interim financial information.

The undersigned registrant hereby further undertakes that:

For purposes of determining any liability under the Securities Act, the information omitted from the form of prospectus filed as part of this registration statement in reliance upon Rule 430A and contained in a form of prospectus filed by the registrant pursuant to Rule 424(b) (1) or (4) or 497(h) under the Securities Act shall be deemed to be part of this registration statement as of the time it was declared effective.


2.	For the purpose of determining any liability under the Securities Act, each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.
