Each Profits Interest Unit issued pursuant to an Award shall count as one share of Stock for purposes of calculating the aggregate number of shares of Stock available for issuance under the Plan as set forth in this Section 3.1(a) and for purposes of calculating the share limitation set forth in Section 3.3.

(b) To the extent that an Award terminates, expires, or lapses for any reason, any shares of Stock subject to the Award shall again be available for the grant of an Award pursuant to the Plan. Additionally, any shares of Stock tendered or withheld to satisfy the grant or exercise price or tax withholding obligation pursuant to any Award shall again be available for the grant of an Award pursuant to the Plan. To the extent permitted by applicable law or any exchange rule, shares of Stock issued in assumption of, or in substitution for, any outstanding awards of any entity acquired in any form of combination by the Company or any Subsidiary shall not be counted against shares of Stock available for grant pursuant to this Plan. The payment of Dividend Equivalents in conjunction with any outstanding Awards shall not be counted against the shares available for issuance under the Plan. The Committee may adopt reasonable counting procedures to ensure appropriate counting, avoid double counting (as, for example, in the case of tandem or substitute awards), and make adjustments if the number of shares of Stock actually delivered differs from the number of shares previously counted in connection with an Award. Notwithstanding the foregoing, no shares shall become available pursuant to this Section 3.1(b) to the extent that (x) the transaction resulting in the return of shares occurs more than ten years after the date of the most recent shareholder approval of the Plan, or (y) such return of shares would constitute a “material revision” of the Plan subject to stockholder approval under then applicable rules of the New York Stock Exchange (or any other applicable exchange or quotation system).

To the extent that Incentive Stock Options are first exercisable by a Participant in excess of such limitation, the excess shall be considered Non-Qualified Stock Options.

An Incentive Stock Option shall be granted to any individual who, at the date of grant, owns stock possessing more than ten percent of the total combined voting power of all classes of Stock of the Company only if such Option is granted at a price that is not less than 110% of Fair Market Value on the date of grant and the Option is exercisable for no more than five years from the date of grant.

(a) the Company shall transfer to the Participant the number of shares equal to (A) the amount of the payment made by the Participant to the Company pursuant to Section 5.1(c) divided by (B) the Fair Market Value of a share of Common Stock at the time of exercise (the “Services Company Participant Purchased Shares”);

8.10 Granting of Profits Interest Units to Independent Directors.

(a) During the term of the Plan, each person who is an Independent Director as of the effective date of the Registration Statement on Form S-11 with respect to the initial public offering of shares of Stock (the “Pricing Date”) automatically shall be granted (i) 6,448 Profits Interest Units on the Pricing Date, and (ii) 1,612 Profits Interest Units on the date of each annual meeting of stockholders after the Public Trading Date at which the Independent Director is reelected to the Board, commencing with the third annual meeting after the Public Trading Date. During the term of the Plan, each person who is initially elected to the Board after the Pricing Date and who is an Independent Director at the time of such initial election automatically shall be granted (I) 6,448 Profits Interest Units on the date of such initial election, and (II) 1,612 Profits Interest Units on the date of each annual meeting of stockholders after such initial election at which the Independent Director is reelected to the Board, commencing with the third annual meeting after such initial election. Members of the Board who are employees of the Company, the Partnership, the Services Company, or any Subsidiary who subsequently retire from employment with such entities and remain on the Board will not receive an initial Award of Profits Interest Units pursuant to clause (I) of the preceding sentence, but to the extent they are otherwise eligible, will receive, after retirement from such employment, an Award of Profits Interest Units as described in clause (ii) above or clause (II) of the preceding sentence, as applicable. Notwithstanding the foregoing, in the event that an Independent Director does not qualify as an “accredited investor” within the meaning of Regulation D of the Securities Act of 1933, as amended, on the date of any grant of Profits Interest Units to such Independent Director pursuant to this Section 8.10, then such Independent Director shall not receive such grant of Profits Interest Units, and in lieu thereof shall automatically be granted an equivalent number of fully vested shares of Restricted Stock at a per share purchase price equal to the par value of the Stock.

(b) The Profits Interest Units awarded pursuant to subsection (a) above shall be vested in full as of the date of grant. Consistent with the foregoing, the terms and conditions of the Profits Interest Units (including, without limitation, transfer restrictions with respect thereto) shall be set forth in an Award Agreement to be entered into by the Company and each Independent Director which shall evidence the grant of the Profits Interest Units.

8.11 Term. Except as otherwise provided herein, the term of any Award of Performance Shares, Performance Stock Units, Dividend Equivalents, Stock Payments, Deferred Stock, Restricted Stock Units, Profits Interest Units or Other Incentive Award shall be set by the Committee in its discretion.

8.12 Exercise or Purchase Price. The Committee may establish the exercise or purchase price, if any, of any Award of Performance Shares, Performance Stock Units, Deferred Stock, Stock Payments, Restricted Stock Units or Other Incentive Award; provided, however, that such price shall not be less than the par value of a share of Stock on the date of grant, unless otherwise permitted by applicable state law.

18

8.13 Exercise Upon Termination of Employment or Service. An Award of Performance Shares, Performance Stock Units, Dividend Equivalents, Deferred Stock, Stock Payments, Restricted Stock Units, Profits Interest Units and Other Incentive Award shall only be exercisable or payable while the Participant is an Employee, Consultant, a member of the Board or a Services Company Director, as applicable; provided, however, that the Committee in its sole and absolute discretion may provide that an Award of Performance Shares, Performance Stock Units, Dividend Equivalents, Stock Payments, Deferred Stock, Restricted Stock Units, Profits Interest Units or Other Incentive Award may be exercised or paid subsequent to a termination of employment or service, as applicable, or following a Change in Control of the Company, or because of the Participant’s retirement, death or Disability, or otherwise; provided further, that any such provision with respect to Performance Shares or Performance Stock Units shall be subject to the requirements of Section 162(m) of the Code that apply to Qualified Performance-Based Compensation.

ARTICLE 9

PERFORMANCE-BASED AWARDS

9.1 Purpose. The purpose of this Article 9 is to provide the Committee the ability to qualify Awards other than Options and SARs and that are granted pursuant to Articles 6 and 8 as Qualified Performance-Based Compensation. If the Committee, in its discretion, decides to grant a Performance-Based Award to a Covered Employee, the provisions of this Article 9 shall control over any contrary provision contained in Articles 6 or 8; provided, however, that the Committee may in its discretion grant Awards to Covered Employees that are based on Performance Criteria or Performance Goals but that do not satisfy the requirements of this Article 9.

9.2 Applicability. This Article 9 shall apply only to those Covered Employees selected by the Committee to receive Performance-Based Awards. The designation of a Covered Employee as a Participant for a Performance Period shall not in any manner entitle the Participant to receive an Award for the period. Moreover, designation of a Covered Employee as a Participant for a particular Performance Period shall not require designation of such Covered Employee as a Participant in any subsequent Performance Period and designation of one Covered Employee as a Participant shall not require designation of any other Covered Employees as a Participant in such period or in any other period.

9.3 Procedures with Respect to Performance-Based Awards. To the extent necessary to comply with the Qualified Performance-Based Compensation requirements of Section 162(m)(4)(C) of the Code, with respect to any Award granted under Articles 6 and 8 which may

19

be granted to one or more Covered Employees, no later than ninety (90) days following the commencement of any fiscal year in question or any other designated fiscal period or period of service (or such other time as may be required or permitted by Section 162(m) of the Code), the Committee shall, in writing, (a) designate one or more Covered Employees, (b) select the Performance Criteria applicable to the Performance Period, (c) establish the Performance Goals, and amounts of such Awards, as applicable, which may be earned for such Performance Period, and (d) specify the relationship between Performance Criteria and the Performance Goals and the amounts of such Awards, as applicable, to be earned by each Covered Employee for such Performance Period. Following the completion of each Performance Period, the Committee shall certify in writing whether the applicable Performance Goals have been achieved for such Performance Period. In determining the amount earned by a Covered Employee, the Committee shall have the right to reduce or eliminate (but not to increase) the amount payable at a given level of performance to take into account additional factors that the Committee may deem relevant to the assessment of individual or corporate performance for the Performance Period.

9.4 Payment of Performance-Based Awards. Unless otherwise provided in the applicable Award Agreement, a Participant must be employed by the Company or a Company Subsidiary, the Partnership or a Partnership Subsidiary, or the Services Company or a Services Company Subsidiary, on the day a Performance-Based Award for such Performance Period is paid to the Participant. Furthermore, a Participant shall be eligible to receive payment pursuant to a Performance-Based Award for a Performance Period only if the Performance Goals for such period are achieved.

9.5 Additional Limitations. Notwithstanding any other provision of the Plan, any Award which is granted to a Covered Employee and is intended to constitute Qualified Performance-Based Compensation shall be subject to any additional limitations set forth in Section 162(m) of the Code (including any amendment to Section 162(m) of the Code) or any regulations or rulings issued thereunder that are requirements for qualification as qualified performance-based compensation as described in Section 162(m)(4)(C) of the Code, and the Plan shall be deemed amended to the extent necessary to conform to such requirements.

ARTICLE 10

PROVISIONS APPLICABLE TO AWARDS

10.1 Stand-Alone and Tandem Awards. Awards granted pursuant to the Plan may, in the discretion of the Committee, be granted either alone, in addition to, or in tandem with, any other Award granted pursuant to the Plan. Awards granted in addition to or in tandem with other Awards may be granted either at the same time as or at a different time from the grant of such other Awards.

10.2 Award Agreement. Awards under the Plan shall be evidenced by Award Agreements that set forth the terms, conditions and limitations for each Award which may include the term of an Award, the provisions applicable in the event the Participant’s employment or service terminates, and the Company’s authority to unilaterally or bilaterally amend, modify, suspend, cancel or rescind an Award.

20

10.3 Limits on Transfer. No right or interest of a Participant in any Award may be pledged, encumbered, or hypothecated to or in favor of any party other than the Company, the Services Company, the Partnership or a Subsidiary, or shall be subject to any lien, obligation, or liability of such Participant to any other party other than the Company, the Services Company, the Partnership or a Subsidiary. Except as otherwise provided by the Committee, no Award shall be assigned, transferred, or otherwise disposed of by a Participant other than by will or the laws of descent and distribution. The Committee by express provision in the Award or an amendment thereto may permit an Award (other than an Incentive Stock Option) to be transferred to, exercised by and paid to certain persons or entities related to the Participant, including but not limited to members of the Participant’s family, charitable institutions, or trusts or other entities whose beneficiaries or beneficial owners are members of the Participant’s family and/or charitable institutions, or to such other persons or entities as may be expressly approved by the Committee, pursuant to such conditions and procedures as the Committee may establish. Any permitted transfer shall be subject to the condition that the Committee receive evidence satisfactory to it that the transfer is being made for estate and/or tax planning purposes (or to a “blind trust” in connection with the Participant’s termination of employment or service with the Company, the Services Company, the Partnership or a Subsidiary to assume a position with a governmental, charitable, educational or similar non-profit institution) and on a basis consistent with the Company’s lawful issue of securities.

10.4 Beneficiaries. Notwithstanding Section 10.3, a Participant may, in the manner determined by the Committee, designate a beneficiary to exercise the rights of the Participant and to receive any distribution with respect to any Award upon the Participant’s death. A beneficiary, legal guardian, legal representative, or other person claiming any rights pursuant to the Plan is subject to all terms and conditions of the Plan and any Award Agreement applicable to the Participant, except to the extent the Plan and Award Agreement otherwise provide, and to any additional restrictions deemed necessary or appropriate by the Committee. If the Participant is married and resides in a community property state, a designation of a person other than the Participant’s spouse as his or her beneficiary with respect to more than 50% of the Participant’s interest in the Award shall not be effective without the prior written consent of the Participant’s spouse. If no beneficiary has been designated or survives the Participant, payment shall be made to the person entitled thereto pursuant to the Participant’s will or the laws of descent and distribution. Subject to the foregoing, a beneficiary designation may be changed or revoked by a Participant at any time provided the change or revocation is filed with the Committee.

10.5 Certificates; Book Entry Procedures.

(a) Notwithstanding anything herein to the contrary, neither the Company, the Services Company, nor the Partnership shall be required to issue or deliver any certificates evidencing shares of Stock or other securities pursuant to the grant or exercise of any Award, unless and until the Board has determined, with advice of counsel, that the issuance and delivery of such certificates is in compliance with all applicable laws, regulations of governmental authorities and, if applicable, the requirements of any exchange on which the shares of Stock or other securities are listed or traded. All certificates delivered pursuant to the Plan are subject to any stop-transfer orders and other restrictions as the Committee deems necessary or advisable to comply with federal, state, or foreign jurisdiction, securities or other laws, rules and regulations and the rules of any national securities exchange or automated quotation system on which the

21

such securities are listed, quoted, or traded. The Committee may place legends on any certificate to reference restrictions applicable to the Stock or other securities. In addition to the terms and conditions provided herein, the Board may require that a Participant make such reasonable covenants, agreements, and representations as the Board, in its discretion, deems advisable in order to comply with any such laws, regulations, or requirements. The Committee shall have the right to require any Participant to comply with any timing or other restrictions with respect to the settlement or exercise of any Award, including a window-period limitation, as may be imposed in the discretion of the Committee.

(b) Notwithstanding any other provision of the Plan, unless otherwise determined by the Committee or required by any applicable law, rule or regulation, neither the Company, the Services Company, nor the Partnership shall deliver to any Participant certificates evidencing shares of Stock or other securities issued in connection with any Award and instead such shares of Stock or other securities shall be recorded in the books of the Company (or, as applicable, its transfer agent or stock plan administrator).

ARTICLE 11

CHANGES IN CAPITAL STRUCTURE

11.1 Adjustments.

(a) In the event of any stock dividend, stock split, combination or exchange of shares, merger, consolidation, spin-off, recapitalization or other distribution (other than normal cash dividends) of Company assets to stockholders, or any other change affecting the shares of Stock or the share price of the Stock, the Committee shall make such proportionate adjustments, if any, as the Committee in its discretion may deem appropriate to reflect such change with respect to (i) the aggregate number and type of shares that may be issued under the Plan (including, but not limited to, adjustments of the limitations in Sections 3.1 and 3.3); (ii) the terms and conditions of any outstanding Awards (including, without limitation, any applicable Performance Goals or Performance Criteria with respect thereto); and (iii) the grant or exercise price per share for any outstanding Awards under the Plan. Any adjustment affecting an Award intended as Qualified Performance-Based Compensation shall be made consistent with the requirements of Section 162(m) of the Code.

(b) In the event of any transaction or event described in Section 11.1(a) or any unusual or nonrecurring transactions or events affecting the Company, any affiliate of the Company, or the financial statements of the Company or any affiliate (including without limitation any Change in Control), or of changes in applicable laws, regulations or accounting principles, the Committee, in its sole discretion and on such terms and conditions as it deems appropriate, either by the terms of the Award or by action taken prior to the occurrence of such transaction or event and either automatically or upon the Participant’s request, is hereby authorized to take any one or more of the following actions whenever the Committee determines that such action is appropriate in order to prevent dilution or enlargement of the benefits or potential benefits intended to be made available under the Plan or with respect to any Award under the Plan, to facilitate such transactions or events or to give effect to such changes in laws, regulations or principles:

(i) To provide for either (A) termination of any such Award in exchange for an amount of cash and/or other property, if any, equal to the amount that would have been attained upon the exercise of such Award or realization of the Participant’s rights had such Award been currently exercisable or payable or fully vested (and, for the avoidance of doubt, if the Committee determines in good faith that no amount would have been attained upon the exercise of such Award or realization of the Participant’s rights as of the date of the occurrence of the transaction or event described in this Section 11.1(b), then such Award may be terminated by the Company without payment), or (B) the replacement of such Award with other rights or property selected by the Committee in its sole discretion;

22

(ii) To provide that such Award be assumed by the successor or survivor corporation, or a parent or subsidiary thereof, or shall be substituted for by similar options, rights or awards covering the stock or securities of the successor or survivor corporation, or a parent or subsidiary thereof, with appropriate adjustments as to the number and kind of shares and prices;

(iii) To make adjustments in the number and type of shares of Common Stock (or other securities or property) subject to outstanding Awards, and in the number and kind of shares subject to outstanding Restricted Stock or Deferred Stock Awards and/or in the terms and conditions of (including the grant or exercise price), and the criteria included in, outstanding options, rights and awards and options, rights and awards which may be granted in the future

(iv) To provide that such Award shall be exercisable or payable or fully vested with respect to all shares or other securities covered thereby, notwithstanding anything to the contrary in the Plan or the applicable Award Agreement; and

(v) To provide that the Award cannot vest, be exercised or become payable after such event.

11.2 Acceleration Upon Certain Changes in Control. Notwithstanding Section 11.1, if a Change in Control occurs and a Participant’s Awards are not converted, assumed, or replaced by a successor entity, then immediately prior to the Change in Control such Awards shall become fully exercisable and all forfeiture restrictions on such Awards shall lapse. Upon, or in anticipation of, a Change in Control, the Committee may cause any and all Awards outstanding hereunder to terminate at a specific time in the future, including but not limited to the date of such Change in Control, and shall give each Participant the right to exercise such Awards during a period of time as the Committee, in its sole and absolute discretion, shall determine. In the event that the terms of any agreement between the Company, the Services Company, the Partnership or any Subsidiary or affiliate and a Participant contains provisions that conflict with and are more restrictive than the provisions of this Section 11.2, this Section 11.2 shall prevail and control and the more restrictive terms of such agreement (and only such terms) shall be of no force or effect.

11.3 Outstanding Awards – Other Changes. In the event of any other change in the capitalization of the Company or corporate change other than those specifically referred to in this Article 11, the Committee may, in its absolute discretion, make such adjustments in the number

23

and kind of shares or other securities subject to Awards outstanding on the date on which such change occurs and in the per share grant or exercise price of each Award as the Committee may consider appropriate to prevent dilution or enlargement of rights.

11.4 No Other Rights. Except as expressly provided in the Plan, no Participant shall have any rights by reason of any subdivision or consolidation of shares of stock of any class, the payment of any dividend, any increase or decrease in the number of shares of stock of any class or any dissolution, liquidation, merger, or consolidation of the Company or any other corporation. Except as expressly provided in the Plan or pursuant to action of the Committee under the Plan, no issuance by the Company of shares of stock of any class, or securities convertible into shares of stock of any class, shall affect, and no adjustment by reason thereof shall be made with respect to, the number of shares of Stock or other securities subject to an Award or the grant or exercise price of any Award.

ARTICLE 12

ADMINISTRATION

12.1 Committee. Unless and until the Board delegates administration of the Plan to a Committee as set forth below, the Plan shall be administered by the full Board, and for such purposes the term “Committee” as used in this Plan shall be deemed to refer to the Board. The Board, at its discretion or as otherwise necessary to comply with the requirements of Section 162(m) of the Code, Rule 16b-3 promulgated under the Exchange Act or to the extent required by any other applicable rule or regulation, shall delegate administration of the Plan to a Committee. The Committee shall consist solely of two or more members of the Board each of whom is both an “outside director,” within the meaning of Section 162(m) of the Code, and a Non-Employee Director.

ARTICLE 13

EFFECTIVE AND EXPIRATION DATE

13.1 Effective Date. The Plan is effective as of the date the Plan is approved by the Company’s stockholders (the “Effective Date”). The Plan will be deemed to be approved by the stockholders if it receives the affirmative vote of the holders of a majority of the shares of stock of the Company present or represented and entitled to vote at a meeting duly held in accordance with the applicable provisions of the Company’s Bylaws.

13.2 Expiration Date. The Plan will expire on, and no Incentive Stock Option or other Award may be granted pursuant to the Plan after, the earlier of the tenth anniversary of (i) the Effective Date or (ii) the date this Plan is approved by the Board. Any Awards that are outstanding on the tenth anniversary of the Effective Date shall remain in force according to the terms of the Plan and the applicable Award Agreement.

ARTICLE 14

AMENDMENT, MODIFICATION, AND TERMINATION

14.1 Amendment, Modification, And Termination. With the approval of the Board, at any time and from time to time, the Committee may terminate, amend or modify the Plan; provided, however, that (a) to the extent necessary and desirable to comply with any applicable law, regulation, or stock exchange rule, the Company shall obtain stockholder approval of any Plan amendment in such a manner and to such a degree as required, and (b) stockholder approval shall be required for any amendment to the Plan that (i) increases the number of shares available under the Plan (other than any adjustment as provided by Article 11), (ii) permits the Committee to grant Options with an exercise price that is below Fair Market Value on the date of grant, or (iii) permits the Committee to extend the exercise period for an Option beyond ten years from the date of grant. Notwithstanding any provision in this Plan to the contrary, absent approval of the stockholders of the Company, no Option may be amended to reduce the per share exercise price of the shares subject to such Option below the per share exercise price as of the date the Option is granted and, except as permitted by Article 11, no Option may be granted in exchange for, or in connection with, the cancellation or surrender of an Option having a higher per share exercise price.

14.2 Awards Previously Granted. No termination, amendment, or modification of the Plan shall adversely affect in any material way any Award previously granted pursuant to the Plan without the prior written consent of the Participant.

26

ARTICLE 15

GENERAL PROVISIONS

15.1 No Rights to Awards. No Eligible Individual or other person shall have any claim to be granted any Award pursuant to the Plan, and none of the Company, the Services Company, the Partnership or the Committee is obligated to treat Eligible Individuals, Participants or any other persons uniformly.

15.2 No Stockholders Rights. Except as otherwise provided herein, no Participant shall have any of the rights of a stockholder with respect to shares of Stock covered by any Award until the Participant becomes the record owner of such shares of Stock.

15.3 Withholding. The Company, the Services Company, the Partnership or any Subsidiary, as applicable, shall have the authority and the right to deduct or withhold, or require a Participant to remit to the Company, the Services Company, the Partnership or any Subsidiary, as applicable, an amount sufficient to satisfy federal, state, local and foreign taxes (including the Participant’s FICA obligation) required by law to be withheld with respect to any taxable event concerning a Participant arising as a result of this Plan. The Committee may in its discretion and in satisfaction of the foregoing requirement allow a Participant to elect to have the Company, the Services Company, the Partnership or any Subsidiary, as applicable, withhold shares of Stock otherwise issuable under an Award (or allow the return of shares of Stock) having a Fair Market Value equal to the sums required to be withheld. Notwithstanding any other provision of the Plan, the number of shares of Stock which may be withheld with respect to the issuance, vesting, exercise or payment of any Award (or which may be repurchased from the Participant of such Award within six months (or such other period as may be determined by the Committee) after such shares of Stock were acquired by the Participant from the Company) in order to satisfy the Participant’s federal, state, local and foreign income and payroll tax liabilities with respect to the issuance, vesting, exercise or payment of the Award shall be limited to the number of shares which have a Fair Market Value on the date of withholding or repurchase equal to the aggregate amount of such liabilities based on the minimum statutory withholding rates for federal, state, local and foreign income tax and payroll tax purposes that are applicable to such supplemental taxable income.

15.4 No Right to Employment or Services. Nothing in the Plan or any Award Agreement shall interfere with or limit in any way the right of the Company, the Services Company, the Partnership or any Subsidiary to terminate any Participant’s employment or services at any time, nor confer upon any Participant any right to continue in the employ or service of the Company, the Services Company, the Partnership or any Subsidiary.

15.5 Unfunded Status of Awards. The Plan is intended to be an “unfunded” plan for incentive compensation. With respect to any payments not yet made to a Participant pursuant to an Award, nothing contained in the Plan or any Award Agreement shall give the Participant any rights that are greater than those of a general creditor of the Company, the Services Company, the Partnership or any Subsidiary.

27

15.6 Indemnification. To the extent allowable pursuant to applicable law, each member of the Committee or of the Board shall be indemnified and held harmless by the Company, the Services Company and/or the Partnership from any loss, cost, liability, or expense that may be imposed upon or reasonably incurred by such member in connection with or resulting from any claim, action, suit, or proceeding to which he or she may be a party or in which he or she may be involved by reason of any action or failure to act pursuant to the Plan and against and from any and all amounts paid by him or her in satisfaction of judgment in such action, suit, or proceeding against him or her; provided he or she gives the Company, the Services Company and the Partnership an opportunity, at their own expense, to handle and defend the same before he or she undertakes to handle and defend it on his or her own behalf. The foregoing right of indemnification shall not be exclusive of any other rights of indemnification to which such persons may be entitled pursuant to the Company’s Certificate of Incorporation or Bylaws, as a matter of law, or otherwise, or any power that the Company, the Services Company and/or the Partnership may have to indemnify them or hold them harmless.

15.7 Relationship to other Benefits. No payment pursuant to the Plan shall be taken into account in determining any benefits pursuant to any pension, retirement, savings, profit sharing, group insurance, welfare or other benefit plan of the Company, the Services Company, the Partnership or any Subsidiary except to the extent otherwise expressly provided in writing in such other plan or an agreement thereunder.

15.8 Expenses. The expenses of administering the Plan shall be borne by the Company, the Services Company, the Partnership and their Subsidiaries.

15.9 Titles and Headings. The titles and headings of the Sections in the Plan are for convenience of reference only and, in the event of any conflict, the text of the Plan, rather than such titles or headings, shall control.

15.10 Fractional Shares. No fractional shares of Stock shall be issued and the Committee shall determine, in its discretion, whether cash shall be given in lieu of fractional shares or whether such fractional shares shall be eliminated by rounding up or down as appropriate.

15.11 Limitations Applicable to Section 16 Persons. Notwithstanding any other provision of the Plan, the Plan, and any Award granted or awarded to any Participant who is then subject to Section 16 of the Exchange Act, shall be subject to any additional limitations set forth in any applicable exemptive rule under Section 16 of the Exchange Act (including any amendment to Rule 16b-3 of the Exchange Act) that are requirements for the application of such exemptive rule. To the extent permitted by applicable law, the Plan and Awards granted or awarded hereunder shall be deemed amended to the extent necessary to conform to such applicable exemptive rule.

15.12 Government and Other Regulations. The obligation of the Company, the Services Company and the Partnership to make payment of awards in Stock or otherwise shall be subject to all applicable laws, rules, and regulations, and to such approvals by government agencies as may be required. The Company shall be under no obligation to register pursuant to the Securities Act of 1933, as amended, any of the shares of Stock or other securities paid pursuant

28

to the Plan. If the shares or other securities paid pursuant to the Plan may in certain circumstances be exempt from registration pursuant to the Securities Act of 1933, as amended, the Company, the Services Company and the Partnership may restrict the transfer of such shares or other securities in such manner as it deems advisable to ensure the availability of any such exemption.

15.13 Section 83(b) Election Prohibited. No Participant may make an election under Section 83(b) of the Code with respect to any Award under the Plan without the consent of the Company, which the Company may grant or withhold in its sole discretion.

15.14 Grant of Awards to Certain Employees or Consultants. The Company, the Services Company, the Partnership or any Subsidiary may provide through the establishment of a formal written policy or otherwise for the method by which shares of Stock or other securities and/or payment therefor may be exchanged or contributed between the Company and such other party, or may be returned to the Company upon any forfeiture of Stock or other securities by the Participant, for the purpose of ensuring that the relationship between the Company and the Services Company, the Partnership or such Subsidiary remains at arm’s-length.

15.15 Restrictions on Awards. This Plan shall be interpreted and construed in a manner consistent with the Company’s status as a REIT. No Award shall be granted or awarded, and with respect to an Award already granted under the Plan, such Award shall not be exercisable:

(a) to the extent that the grant or exercise of such Award could cause the Participant to be in violation of the Common Stock Ownership Limit or the Aggregate Stock Ownership Limit (each as defined in the Company’s Articles of Incorporation, as amended from time to time); or

(b) if, in the discretion of the Committee, the grant or exercise of such Award could impair the Company’s status as a REIT.

15.16 Governing Law. The Plan and all Award Agreements shall be construed in accordance with and governed by the laws of the State of California.
