Members of any committee shall serve for such term as the Board may determine, subject to removal by the Board at any time. To the extent consistent with applicable law, the Board or the Compensation Committee may authorize one or more officers of the Company to grant Awards to designated classes of Eligible Persons, within limits specifically prescribed by the Board or the Compensation Committee; provided, however, that no such officer shall have or obtain

(a)Except for the terms and conditions explicitly set forth in the Plan and to the extent permitted by applicable law, the Committee shall have full power and exclusive authority, subject to such orders or resolutions not inconsistent with the provisions of the Plan as may from time to time be adopted by the Board or a Committee composed of members of the Board, to (i) select the Eligible Persons to whom Awards may from time to time be granted under the Plan; (ii) determine the type or types of Awards to be granted to each Participant under the Plan; (iii) determine the number of shares of Common Stock to be covered by each Award granted under the Plan; (iv) determine the terms and conditions of any Award granted under the Plan; (v) approve the forms of notice or agreement for use under the Plan; (vi) determine whether, to what extent and under what circumstances Awards may be settled in cash, shares of Common Stock or other property or canceled or suspended; (vii) determine whether, to what extent and under what circumstances cash, shares of Common Stock, other property and other amounts payable with respect to an Award shall be deferred either automatically or at the election of the Participant; (viii)  interpret and administer the Plan and any instrument evidencing an Award, notice or agreement executed or entered into under the Plan; (ix) establish such rules, regulations and sub-plans as it shall deem appropriate for the proper administration and operation of the Plan; (x) delegate ministerial duties to such of the Company’s employees as it so determines; and (xi) make any other determination and take any other action that the Committee deems necessary or desirable for administration of the Plan.

(b)The effect on the vesting of an Award of a Company-approved leave of absence or a Participant’s reduction in hours of employment or service shall be determined by the Company’s Vice President, Human Resources or other person performing that function or, with respect to directors or executive officers, by the Committee, whose determination shall be final.

(c)Decisions of the Committee shall be final, conclusive and binding on all persons, including the Company, any Participant, any stockholder and any Eligible Person. A majority of the members of the Committee may determine its actions.

Subject to adjustment from time to time as provided in Section 12.1, the aggregate maximum number of shares of Common Stock available for issuance under the Plan shall be:

(a)1,000,000 shares; plus

(b)(i) any shares set aside and reserved for issuance, but not issued or subject to outstanding awards, under the Company’s 2005 Stock Incentive Plan (the “Prior Plan”) on the Effective Date and (ii)  any shares subject to outstanding awards under the Prior Plan on the Effective Date that cease to be subject to such awards following the Effective Date (other than by reason of exercise or settlement of the awards to the extent they are exercised for or settled in vested or nonforfeitable shares) shall cease to be set aside or reserved for issuance pursuant to the Prior Plan, and shall instead be set aside and reserved for issuance pursuant to the Plan, effective on the respective dates on which such shares may be added to the Plan by reason of this paragraph (b), up to an aggregate maximum of 793,437 shares.

Shares issued under the Plan shall be drawn from authorized and unissued shares or shares now held or subsequently acquired by the Company as treasury shares.

(a)If any Award lapses, expires, terminates or is canceled prior to the issuance of shares thereunder or if shares of Common Stock are issued under the Plan to a Participant and thereafter are forfeited to the Company, the shares subject to such Awards and the forfeited shares shall again be available for issuance under the Plan. Any shares of Common Stock (i) tendered by a Participant or retained by the Company as full or partial payment to the Company for the purchase price of an Award or to satisfy tax withholding obligations in connection with an Award or (ii) covered by an Award that is settled in cash, or in a manner such that some or all of the shares of Common Stock covered by the Award are not issued, shall not be available for Awards under the Plan.

(b)The Committee shall also, without limitation, have the authority to grant Awards as an alternative to or as the form of payment for grants or rights earned or due under other compensation plans or arrangements of the Company.

(c)Notwithstanding any other provision of the Plan to the contrary, the Committee may grant Substitute Awards under the Plan. Substitute Awards shall not reduce the number of shares authorized for issuance under the Plan. In the event that an Acquired Entity has shares available for awards or grants under one or more preexisting plans not adopted in contemplation of such acquisition or combination, then, to the extent determined by the Board or the Committee, the shares available for grant pursuant to the terms of such preexisting plan (as adjusted, to the extent appropriate, using the exchange ratio or other adjustment or valuation ratio or formula used in such acquisition or combination to determine the consideration payable to holders of common stock of the entities that are parties to such acquisition or combination) may be used for Awards under the Plan and shall not reduce the number of shares of Common Stock authorized for issuance under the Plan; provided, however, that Awards using such available shares shall not be made after the date awards or grants could have been made under the terms of such preexisting plans, absent the acquisition or combination, and shall only be made to individuals who were not employees or directors of the Company or a Related Company prior to such acquisition or combination. In the event that a written agreement between the Company and an Acquired Entity pursuant to which a merger or consolidation is completed is approved by the Board and that agreement sets forth the terms and conditions of the substitution for or assumption of outstanding awards of the Acquired Entity, those terms and conditions shall be deemed to be the action of the Committee without any further action by the Committee, except

as may be required for compliance with Rule 16b-3 under the Exchange Act, and the persons holding such awards shall be deemed to be Participants.

(a)Subject to adjustment as provided in Section 12.1, the aggregate number of shares that may be issued pursuant to Awards granted under the Plan (that either (i) contain no restrictions or restrictions based solely on continuous employment or services over fewer than three years (except if accelerated pursuant to a Change in Control or in the event of a Termination of Service) or (ii) vest over less than one year (except if accelerated pursuant to a Change in Control or in the event of a Termination of Service) based on factors other than solely continuous employment or services shall not exceed 10% of the aggregate maximum number of shares specified in Section 4.1. In addition, if and to the extent the Committee accelerates vesting or exercisability of an Award or otherwise acts to waive or lapse any restriction on an Award, other than in connection with a Participant’s death, Disability or Retirement or a Change in Control, the shares covered by such Committee action shall similarly count towards the foregoing 10% limitation.

(b)    Notwithstanding anything contained herein to the contrary, no Participant may receive Common Stock pursuant to or in connection with the payment of any Award to the extent it would result in a violation of the stock ownership limitations set forth in the Company’s Restated Certificate of Incorporation or would impair the Company’s status as a “real estate investment trust” within the meaning of Sections 856 through 860 of the Code.

An Award may be granted to any employee, officer or director of the Company or a Related Company whom the Committee from time to time selects.

The Committee shall have the authority, in its sole discretion, to determine the type or types of Awards to be granted under the Plan. Such Awards may be granted either alone or in addition to or in tandem with any other type of Award. Any Award settlement may be subject to such conditions, restrictions and contingencies as the Committee shall determine.

Awards granted under the Plan shall be evidenced by a written, including an electronic, instrument that shall contain such terms, conditions, limitations and restrictions as the Committee shall deem advisable and that are not inconsistent with the Plan.

The Committee may permit or require a Participant to defer receipt of the payment of any Award. If any such deferral election is permitted or required, the Committee, in its sole discretion, shall establish rules and procedures for such payment deferrals, which may include the grant of additional Awards or provisions for the payment or crediting of interest or dividend equivalents, including converting such credits to deferred stock unit equivalents. Deferral of any

Award or payment thereunder shall satisfy the requirements for exemption from Section 409A or satisfy the requirements of Section 409A as determined by the Committee prior to such deferral.

Participants may, if the Committee so determines, be credited with dividends or dividend equivalents paid with respect to shares of Common Stock underlying an Award in a manner determined by the Committee in its sole discretion. The Committee may apply any restrictions to the dividends or dividend equivalents that the Committee deems appropriate. The Committee, in its sole discretion, may determine the form of payment of dividends or dividend equivalents, including cash, shares of Common Stock, Restricted Stock or Stock Units. Notwithstanding the foregoing, if any Award for which dividends or dividend equivalents have been granted has its vesting, payment or grant dependent on the achievement of one or more performance goals, then the dividends or dividend equivalents shall accrue and be paid only to the extent the Award becomes vested or payable. Also notwithstanding the foregoing, the crediting of dividends or dividend equivalents must comply with or qualify for an exemption under Section 409A.

The Committee may grant Stock Awards, Restricted Stock and Stock Units on such terms and conditions and subject to such repurchase or forfeiture restrictions, if any, which may be based on continuous service with the Company or a Related Company or the achievement of any performance goals, as the Committee shall determine in its sole discretion, which terms, conditions and restrictions shall be set forth in the instrument evidencing the Award.

Upon the satisfaction of any terms, conditions and restrictions prescribed with respect to Restricted Stock or Stock Units, or upon a Participant’s release from any terms, conditions and restrictions on Restricted Stock or Stock Units, as determined by the Committee, and subject to the provisions of Section 11, (a) the shares covered by each Award of Restricted Stock shall become freely transferable by the Participant, and (b) Stock Units shall be paid in shares of Common Stock or, if set forth in the instrument evidencing the Awards, in cash or a combination of cash and shares of Common Stock. Any fractional shares subject to such Awards shall be paid as provided in the policy adopted by the Committee or, if none, in the instrument evidencing the Award.

The Committee, in its sole discretion, may waive the repurchase or forfeiture period and any other terms, conditions or restrictions on any Restricted Stock or Stock Unit under such circumstances and subject to such terms and conditions as the Committee shall deem appropriate.

The Committee may grant Awards of Performance Shares, designate the Participants to whom Performance Shares are to be awarded and determine the number of Performance Shares and the terms and conditions of each such Award. Performance Shares shall consist of a unit valued by reference to a designated number of shares of Common Stock, the value of which may

be paid to the Participant by delivery of shares of Common Stock or, if set forth in the instrument evidencing the Award, of such property as the Committee shall determine, including, without limitation, cash, shares of Common Stock, other property, or any combination thereof, upon the attainment of performance goals, as established by the Committee, and other terms and conditions specified by the Committee. Notwithstanding the foregoing, the amount to be paid under an Award of Performance Shares may be adjusted on the basis of such further consideration as the Committee shall determine in its sole discretion.

The Committee may grant Awards of Performance Units, designate the Participants to whom Performance Units are to be awarded and determine the number of Performance Units and the terms and conditions of each such Award. Performance Units shall consist of a unit valued by reference to a designated amount of property other than shares of Common Stock, which value may be paid to the Participant by delivery of such property as the Committee shall determine, including, without limitation, cash, shares of Common Stock, other property, or any combination thereof, upon the attainment of performance goals, as established by the Committee, and other terms and conditions specified by the Committee. Notwithstanding the foregoing, the amount to be paid under an Award of Performance Units may be adjusted on the basis of such further consideration as the Committee shall determine in its sole discretion.

Subject to the terms of the Plan and such other terms and conditions as the Committee deems appropriate, the Committee may grant other incentives payable in cash or in shares of Common Stock under the Plan.

The Company may require the Participant to pay to the Company or a Related Company, as applicable, the amount of (a) any taxes that the Company or a Related Company is required by applicable federal, state, local or foreign law to withhold with respect to the grant, vesting or exercise of an Award (“tax withholding obligations”) and (b) any amounts due from the Participant to the Company or to any Related Company (“other obligations”). Notwithstanding any other provision of the Plan to the contrary, the Company shall not be required to issue any shares of Common Stock or otherwise settle an Award under the Plan until such tax withholding obligations and other obligations are satisfied.

The Committee may permit or require a Participant to satisfy all or part of the Participant’s tax withholding obligations and other obligations by: (a) paying cash to the Company or a Related Company, (b) having the Company or a Related Company, as applicable, withhold an amount from any cash amounts otherwise due or to become due from the Company or a Related Company to the Participant, (c) having the Company withhold a number of shares of Common Stock that would otherwise be issued to the Participant (or become vested, in the case of Restricted Stock) having a Fair Market Value equal to the tax withholding obligations and other obligations, (d) surrendering a number of shares of Common Stock the Participant already

owns having a value equal to the tax withholding obligations and other obligations, (e) selling shares of Common Stock issued under an Award on the open market or to the Company, or (f) taking such other action as may be necessary in the opinion of the Committee to satisfy any applicable tax withholding obligations. The value of the shares so withheld or surrendered may not exceed the employer’s minimum required tax withholding rate, or such other applicable rate as is necessary to avoid adverse treatment for financial accounting purposes, as determined by the Committee its sole discretion.

No Award or interest in an Award may be sold, assigned, pledged (as collateral for a loan or as security for the performance of an obligation or for any other purpose) or transferred by a Participant or made subject to attachment or similar proceedings otherwise than by will or by the applicable laws of descent and distribution, except to the extent, at the discretion of the Committee, the instrument evidencing the Award permits the Participant to designate one or more beneficiaries on a Company-approved form who may exercise the Award or receive payment under the Award after the Participant’s death. Notwithstanding the foregoing, the Committee, in its sole discretion, may permit a Participant to assign or transfer an Award without consideration, subject to such terms and conditions as the Committee shall specify.

(a)In the event that, at any time or from time to time, a stock dividend, stock split, spin off, combination or exchange of shares, recapitalization, merger, consolidation, distribution to stockholders other than a normal cash dividend, or other change in the Company’s corporate or capital structure results in (i) the outstanding shares of Common Stock, or any securities exchanged therefor or received in their place, being exchanged for a different number or kind of securities of the Company or (ii) new, different or additional securities of the Company or any other company being received by the holders of shares of Common Stock, or the declaration of a dividend payable in cash that has a material effect on the price of issued shares, then the Committee shall make proportional adjustments in (A) the maximum number and kind of securities available for issuance under the Plan; (B) the maximum numbers and kind of securities set forth in Section 13.3; (C) the maximum number and kind of securities set forth in Section 4.3; and (D) the number and kind of securities that are subject to any outstanding Award and, if applicable, the per share price of such securities.

(b)    Adjustments, if any, and any determinations or interpretations made by the Committee as to whether any adjustment shall be made, including any determination of whether a distribution is other than a normal cash dividend or is a cash dividend that will have a material effect on the price of issued shares, and the terms of any of the foregoing adjustments shall be conclusive and binding.

(c)    Notwithstanding the foregoing, the issuance by the Company of shares of stock of any class, or securities convertible into shares of stock of any class, for cash or property, or for labor or services rendered, either upon direct sale or upon the exercise of rights or warrants to subscribe therefor, or upon conversion of shares or obligations of the Company convertible into such shares or other securities, shall not affect, and no adjustment by reason thereof shall be

made with respect to, outstanding Awards. Also notwithstanding the foregoing, a dissolution or liquidation of the Company or a Change in Control shall not be governed by this Section 12.1 but shall be governed by Sections 12.2 and 12.3, respectively.

To the extent not previously exercised or settled, and unless otherwise determined by the Committee in its sole discretion, Awards shall terminate immediately prior to the dissolution or liquidation of the Company. To the extent a vesting condition, forfeiture provision or repurchase right applicable to an Award has not been waived by the Committee, the Award shall be forfeited immediately prior to the consummation of the dissolution or liquidation.

Notwithstanding any other provision of the Plan to the contrary, unless the Committee shall determine otherwise in the instrument evidencing the Award or in a written employment, services or other agreement between the Participant and the Company or a Related Company, in the event of a Change in Control:

(a)If the Change in Control is a Business Combination in which Awards could be converted, assumed, substituted for or replaced by the Successor Company, then, if and to the extent that the Successor Company converts, assumes, substitutes or replaces an Award, other than Performance Shares, Performance Units and other outstanding Awards that are subject to vesting based on the achievement of specified performance goals, the vesting restrictions or forfeiture provisions applicable to such Award shall not be accelerated or lapse, and all such vesting restrictions or forfeiture provisions shall continue with respect to any shares of the Successor Company or other consideration that may be received with respect to such Award. If and to the extent that Awards, other than Performance Shares, Performance Units and other outstanding Awards that are subject to vesting based on the achievement of specified performance goals, are not converted, assumed, substituted for or replaced by the Successor Company, such Awards shall become fully vested and exercisable or payable, and all applicable restrictions or forfeiture provisions shall lapse, immediately prior to the Change in Control and such Awards shall terminate at the effective time of the Change in Control.

If the Change in Control is not a Business Combination in which Awards could be converted, assumed, substituted for or replaced by the Successor Company, all outstanding Awards, other than Performance Shares, Performance Units and other outstanding Awards that are subject to vesting based on the achievement of specified performance goals, shall become fully vested and exercisable or payable, and all applicable restrictions or forfeiture provisions shall lapse, immediately prior to the Change in Control and shall terminate at the effective time of the Change in Control.

For the purposes of this Section 12.3(a), an Award shall be considered converted, assumed, substituted for or replaced by the Successor Company if following the Business Combination the right confers the right to purchase or receive, for each share of Common Stock subject to the Award immediately prior to the Business Combination, the consideration (whether stock, cash or other securities or property) received in the Business Combination by holders of Common Stock for each share held on the effective date of the transaction (and if holders were

offered a choice of consideration, the type of consideration chosen by the holders of a majority of the outstanding shares); provided, however, that if such consideration received in the Business Combination is not solely common stock of the Successor Company, the Committee may, with the consent of the Successor Company, provide for the consideration to be received pursuant to the Award, for each share of Common Stock subject thereto, to be solely common stock of the Successor Company substantially equal in Fair Market Value to the per share consideration received by holders of Common Stock in the Business Combination. The determination of such substantial equality of value of consideration shall be made by the Committee, and its determination shall be conclusive and binding.

(b)All Performance Shares or Performance Units or other outstanding Awards that are subject to vesting based on the achievement of specified performance goals and that are earned and outstanding as of the date the Change in Control is determined to have occurred and for which the payout level has been determined shall be payable in full in accordance with the payout schedule pursuant to the instrument evidencing the Award or a program adopted pursuant to the Plan. Any remaining outstanding Performance Shares or Performance Units or other outstanding Awards that are subject to vesting based on the achievement of specified performance goals (including any applicable performance period) for which the payout level has not been determined shall be payable in accordance with the terms and payout schedule pursuant to the instrument evidencing the Award. Any existing deferrals or other restrictions not waived by the Committee in its sole discretion shall remain in effect.

(c)Notwithstanding the foregoing, the Committee, in its sole discretion, may instead provide in the event of a Change in Control that is a Business Combination that a Participant’s outstanding Awards shall terminate upon or immediately prior to such Business Combination and that such Participant shall receive, in exchange therefor, a cash payment equal to the amount (if any) by which (x) the value of the per share consideration received by holders of Common Stock in the Business Combination, or, in the event the Business Combination is one of the transactions listed under subsection (c) in the definition of Business Combination or otherwise does not result in direct receipt of consideration by holders of Common Stock, the value of the deemed per share consideration received, in each case as determined by the Committee in its sole discretion, multiplied by the number of shares of Common Stock subject to such outstanding Awards (to the extent then vested and exercisable or whether or not then vested and exercisable, as determined by the Committee in its sole discretion) exceeds (y) if applicable, the respective aggregate exercise price or grant price for such Awards.

(d)For the avoidance of doubt, nothing in this Section 12.3 requires all outstanding Awards to be treated similarly.

Subject to Sections 12.2 and 12.3, the Committee shall have the discretion, exercisable at any time before a sale, merger, consolidation, reorganization, liquidation, dissolution or change of control of the Company, as defined by the Committee, to take such further action as it determines to be necessary or advisable with respect to Awards. Such authorized action may include (but shall not be limited to) establishing, amending or waiving the type, terms, conditions or duration of, or restrictions on, Awards so as to provide for earlier, later, extended or additional time for exercise, lifting restrictions and other modifications, and the Committee may take such

actions with respect to all Participants, to certain categories of Participants or only to individual Participants. The Committee may take such action before or after granting Awards to which the action relates and before or after any public announcement with respect to such sale, merger, consolidation, reorganization, liquidation, dissolution or change of control that is the reason for such action.

The grant of Awards shall in no way affect the Company’s right to adjust, reclassify, reorganize or otherwise change its capital or business structure or to merge, consolidate, dissolve, liquidate or sell or transfer all or any part of its business or assets.

In the event of any adjustment in the number of shares covered by any Award, each such Award shall cover only the number of full shares resulting from such adjustment, and any fractional shares resulting from such adjustment shall be disregarded.

Notwithstanding any other provision of the Plan to the contrary, (a) any adjustments made pursuant to this Section 12 to Awards that are considered “deferred compensation” within the meaning of Section 409A shall be made in compliance with the requirements of Section 409A and (b) any adjustments made pursuant to this Section 12 to Awards that are not considered “deferred compensation” subject to Section 409A shall be made in such a manner as to ensure that after such adjustment the Awards either (i) continue not to be subject to Section 409A or (ii) comply with the requirements of Section 409A.

Notwithstanding any other provision of the Plan to the contrary, if the Committee determines, at the time Awards are granted to a Participant who is, or is likely to be as of the end of the tax year in which the Company would claim a tax deduction in connection with such Award, a Covered Employee, then the Committee may provide that this Section 13 is applicable to such Award.

(a)If an Award is subject to this Section 13, then the lapsing of restrictions thereon and the distribution of cash, shares of Common Stock or other property pursuant thereto, as applicable, shall be subject to the achievement of one or more objective performance goals established by the Committee, which shall be based on the attainment of specified levels of one of or any combination of the following “performance criteria” for the Company as a whole or any business unit of the Company, as reported or calculated by the Company: total stockholder return, stock price increase, return on equity, return on capital, earnings per share, EBIT (earnings before interest and taxes), EBITDA (earnings before interest, taxes, depreciation and amortization or earnings before interest, taxes, depreciation and amortization and cost basis in real property sold), EBITDDA (earnings before interest, taxes, depletion, depreciation and amortization or earnings before interest, taxes, depletion, depreciation and amortization and cost basis in real property sold), ongoing earnings, cash flow (including operating cash flow, free cash flow, discounted cash flow return on investment, and cash flow in excess of costs of capital),

EVA (economic value added), economic profit (net operating profit after tax, less a cost of capital charge), FFO (funds from operations equal to net income plus non-cash charges for depletion, depreciation and amortization and the cost basis in real property sold), SVA (stockholder value added), revenues, net income, operating income, pre-tax profit margin, performance against business plan, market share, operating margins, credit rating, dividend payments, expenses, retained earnings, working capital, financial ratios, yield on investment, completion of acquisitions, divestitures and corporate restructurings (together, the “Performance Criteria”).

(b)Such performance goals also may be based on the achievement of specified levels of Company performance (or performance of an applicable affiliate or business unit of the Company) under one or more of the Performance Criteria described above relative to the performance of other corporations. Such performance goals shall be set by the Committee within the time period prescribed by, and shall otherwise comply with the requirements of, Section 162(m) of the Code, or any successor provision thereto, and the regulations thereunder.

(c)The Committee may provide in any such Award that any evaluation of performance may include or exclude any of the following events that occurs during a performance period: (i) asset write-downs, (ii) litigation or claim judgments or settlements, (iii) the effect of changes in tax laws, accounting principles, or other laws or provisions affecting reported results, (iv) any reorganization and restructuring programs, (v) extraordinary nonrecurring items as described in Accounting Standards Codification 225-20 (or any successor provision) and/or in Management’s Discussion and Analysis of Financial Condition and Results of Operations appearing in the Company’s annual report to stockholders for the applicable year, (vi) acquisitions or divestitures, (vii) foreign exchange gains and losses, (viii) gains and losses on asset sales, and (ix) impairments. To the extent such inclusions or exclusions affect Awards to Covered Employees, they shall be prescribed in a form that satisfies the requirements for “performance-based compensation” within the meaning of Section 162(m)(4)(C) of the Code, or any successor provision thereto.

(a)After the completion of each performance period, the Compensation Committee shall certify the extent to which any performance goal established under this Section 13 has been satisfied, and the amount payable as a result thereof, prior to payment, settlement or vesting, as applicable, of any Award subject to this Section 13.

(b)Notwithstanding any provision of the Plan other than Section 12, with respect to any Award that is subject to this Section 13, the Committee may adjust downwards, but not upwards, the amount payable pursuant to such Award, and the Committee may not waive the achievement of the applicable performance goals except in the case of the death or disability of the Covered Employee.

(a)No Covered Employee may be granted Awards other than Performance Units subject to this Section 13 in the aggregate in any calendar-year period with respect to more than 300,000 shares of Common Stock for such Awards, except that the Company may make additional one-time grants of such Awards for up to 300,000 shares to newly hired or newly promoted individuals, which numbers shall be calculated and adjusted pursuant to Section 12.1 in a manner that satisfies the requirements for “performance-based compensation” within the meaning of Section 162(m)(4)(C) of the Code, or any successor provision thereto. The maximum dollar value payable with respect to Performance Units or other awards payable in

cash subject to this Section 13 and granted to any Covered Employee in any calendar-year period is $10,000,000.

(b)The Committee shall have the power to impose such other restrictions on Awards subject to this Section 13 as it may deem necessary or appropriate to ensure that such Awards satisfy all requirements for “performance-based compensation” within the meaning of Section 162(m)(4)(C) of the Code, or any successor provision thereto.

Notwithstanding any other provision of the Plan to the contrary and to the maximum extent allowed by law, Awards granted under the Plan shall be subject to (a) the Potlatch Corporation Incentive Compensation Recovery Policy, as it may be amended from time to time, and (b) any other compensation recovery policies as may be adopted from time to time by the Company to comply with applicable law and/or stock exchange requirements, or otherwise, to the extent determined by the Committee in its discretion to be applicable to a Participant.

The Board or the Compensation Committee may amend, suspend or terminate the Plan or any portion of the Plan at any time and in such respects as it shall deem advisable; provided, however, that, to the extent required by applicable law, regulation or stock exchange rule, stockholder approval shall be required for any amendment to the Plan; and provided, further, that any amendment that requires stockholder approval may be made only by the Board. Subject to Section 15.3, the Committee may amend the terms of any outstanding Award, prospectively or retroactively.

Unless sooner terminated as provided herein, the Plan shall automatically terminate ten years from the Effective Date. After the Plan is terminated, no future Awards may be granted, but Awards previously granted shall remain outstanding in accordance with their terms and conditions and the Plan’s terms and conditions.

The amendment, suspension or termination of the Plan or a portion thereof or the amendment of an outstanding Award shall not, without the Participant’s consent, materially adversely affect any rights under any Award theretofore granted to the Participant under the Plan. Notwithstanding the foregoing, any adjustments made pursuant to Section 12 shall not be subject to these restrictions.

(a)No individual or Participant shall have any claim to be granted any Award under the Plan, and the Company has no obligation for uniformity of treatment of Participants under the Plan.

(b)Furthermore, nothing in the Plan or any Award granted under the Plan shall be deemed to constitute an employment contract or confer or be deemed to confer on any Participant any right to continue in the employ of, or to continue any other relationship with, the Company or any Related Company or limit in any way the right of the Company or any Related Company to terminate a Participant’s employment or other relationship at any time, with or without cause.

(a)Notwithstanding any other provision of the Plan, the Company shall have no obligation to issue or deliver any shares of Common Stock under the Plan or make any other distribution of benefits under the Plan unless, in the opinion of the Company’s counsel, such issuance, delivery or distribution would comply with all applicable laws (including, without limitation, the requirements of the Securities Act or the laws of any state or foreign jurisdiction) and the applicable requirements of any securities exchange or similar entity.

(b)The Company shall be under no obligation to any Participant to register for offering or resale or to qualify for exemption under the Securities Act, or to register or qualify under the laws of any state or foreign jurisdiction, any shares of Common Stock, security or interest in a security paid or issued under, or created by, the Plan, or to continue in effect any such registrations or qualifications if made.

(c)The inability of the Company or impracticability for the Company, as determined by the Committee in its sole discretion, to obtain or maintain approval from any regulatory body having jurisdiction or to comply with applicable requirements, which approval and compliance are deemed by the Company’s counsel to be necessary to the lawful issuance, delivery, and sale of any shares of Common Stock, shall relieve the Company of any liability in respect of the failure to issue, deliver, or sell such shares as to which the requisite approval has not been obtained or as to which any necessary requirements are not met.

(d)As a condition to the receipt of Common Stock pursuant to an Award under the Plan, the Company may require (i) the Participant to represent and warrant at the time of any such exercise or receipt that such shares are being purchased or received only for the Participant’s own account and without any present intention to sell or distribute such shares and (ii) such other action or agreement by the Participant as may from time to time be necessary to comply with federal, state and foreign securities laws. At the option of the Company, a stop-transfer order against any such shares may be placed on the official stock books and records of the Company, and a legend indicating that such shares may not be pledged, sold or otherwise transferred, unless an opinion of counsel is provided (concurred in by counsel for the Company) stating that such transfer is not in violation of any applicable law or regulation, may be stamped on stock certificates to ensure exemption from registration. The Committee may also require the Participant to execute and deliver to the Company a purchase agreement or such other agreement as may be in use by the Company at such time that describes certain terms and conditions applicable to the shares.

(e)To the extent the Plan or any instrument evidencing an Award provides for issuance of stock certificates to reflect the issuance of shares of Common Stock, the issuance may be effected on a noncertificated basis, to the extent not prohibited by applicable law or the applicable rules of any stock exchange.

(a)Each person who is or shall have been a member of the Board, the Compensation Committee or a committee of the Board, or an officer of the Company to whom authority was delegated in accordance with Section 3, shall be indemnified and held harmless by the Company against and from any loss, cost, liability or expense that may be imposed upon or reasonably incurred by such person in connection with or resulting from any claim, action, suit or proceeding to which such person may be a party or in which such person may be involved by reason of any action taken or failure to act under the Plan and against and from any and all amounts paid by such person in settlement thereof, with the Company’s approval, or paid by such person in satisfaction of any judgment in any such claim, action, suit or proceeding against such person; provided, however, unless such loss, cost, liability or expense is a result of such person’s own willful misconduct or except as expressly provided by statute, that such person shall give the Company an opportunity, at its own expense, to handle and defend the same before such person undertakes to handle and defend it on such person’s own behalf.

(b)The foregoing right of indemnification shall not be exclusive of any other rights of indemnification to which such person may be entitled under the Company’s certificate of incorporation or bylaws, as a matter of law, or otherwise, or of any power that the Company may have to indemnify or hold harmless.

Unless otherwise provided by the Committee or in the instrument evidencing the Award or in a written employment, services or other agreement, no Award, other than a Stock Award or Restricted Stock Award, shall entitle the Participant to any cash dividend, voting or other right of a stockholder unless and until the date of issuance under the Plan of the shares that are the subject of such Award.

(a)The Plan and Awards granted under the Plan are intended to be exempt from the requirements of Section 409A to the maximum extent possible, whether pursuant to the short-term deferral exception described in Treasury Regulation Section 1.409A-1(b)(4) or otherwise. To the extent Section 409A is applicable to the Plan or any Award granted under the Plan, it is intended that the Plan and any Awards granted under the Plan comply with the deferral, payout and other limitations and restrictions imposed under Section 409A. Notwithstanding any other provision of the Plan or any Award granted under the Plan to the contrary, the Plan and any Award granted under the Plan shall be interpreted, operated and administered in a manner consistent with such intentions. Without limiting the generality of the foregoing, and notwithstanding any other provision of the Plan or any Award granted under the Plan to the contrary, (i) with respect to any payments and benefits under the Plan or any Award granted under the Plan to which Section 409A applies, all references in the Plan or any Award granted under the Plan to the termination of the Participant’s employment or service are intended to mean the Participant’s “separation from service,” within the meaning of Section 409A(a)(2)(A)(i) of the Code, and (ii) each payment made under this Plan and any Award granted under the Plan shall be treated as a separate payment and the right to a series of installment payments under this Plan or any such Award shall be treated as a right to a series of separate payments. In addition, if the Participant is a “specified employee,” within the meaning of Section 409A, then to the extent

necessary to avoid subjecting the Participant to the imposition of any additional tax under Section 409A, amounts that would otherwise be payable under the Plan or any Award granted under the Plan during the six-month period immediately following the Participant’s “separation from service,” within the meaning of Section 409A(a)(2)(A)(i) of the Code, shall not be paid to the Participant during such period, but shall instead be accumulated and paid to the Participant (or, in the event of the Participant’s death, the Participant’s estate) in a lump sum on the first business day after the earlier of the date that is six months following the Participant’s separation from service or the Participant’s death. Notwithstanding any other provision of the Plan to the contrary, the Committee, to the extent it deems necessary or advisable in its sole discretion, reserves the right, but shall not be required, to unilaterally amend or modify the Plan and any Award granted under the Plan so that the Award qualifies for exemption from or complies with Section 409A of the Code; provided, however, that the Committee makes no representations that Awards granted under the Plan shall be exempt from or comply with Section 409A of the Code and makes no undertaking to preclude Section 409A from applying to Awards granted under the Plan.

(b)Also notwithstanding any other provision of the Plan to the contrary, the Board or the Committee shall have broad authority to amend the Plan or any outstanding Award without the consent of the Participant to the extent the Board or the Committee deems necessary or advisable to comply with, or take into account, changes in applicable tax laws, securities laws, accounting rules or other applicable laws, rules or regulations.

Without amending the Plan, the Committee may grant Awards to Eligible Persons who are foreign nationals on such terms and conditions different from those specified in the Plan as may, in the judgment of the Committee, be necessary or desirable to foster and promote achievement of the purposes of the Plan and shall have the authority to adopt such modifications, procedures, subplans and the like as may be necessary or desirable to comply with provisions of the laws or regulations of other countries or jurisdictions in which the Company or any Related Company may operate or have employees to ensure the viability of the benefits from Awards granted to Participants employed in such countries or jurisdictions, meet the requirements that permit the Plan to operate in a qualified or tax-efficient manner, comply with applicable foreign laws or regulations and meet the objectives of the Plan.

The Plan is intended to constitute an “unfunded” plan. Nothing contained herein shall require the Company to segregate any monies or other property, or shares of Common Stock, or to create any trusts, or to make any special deposits for any immediate or deferred amounts payable to any Participant, and no Participant shall have any rights that are greater than those of a general unsecured creditor of the Company.

All obligations of the Company under the Plan with respect to Awards shall be binding on any successor to the Company, whether the existence of such successor is the result of a direct or indirect purchase, merger, consolidation, or otherwise, of all or substantially all the business and/or assets of the Company.

If any provision of the Plan or any Award is determined to be invalid, illegal or unenforceable in any jurisdiction, or as to any person, or would disqualify the Plan or any Award under any law deemed applicable by the Committee, such provision shall be construed or deemed amended to conform to applicable laws, or, if it cannot be so construed or deemed amended without, in the Committee’s determination, materially altering the intent of the Plan or the Award, such provision shall be stricken as to such jurisdiction, person or Award, and the remainder of the Plan and any such Award shall remain in full force and effect.

The Plan, all Awards granted thereunder and all determinations made and actions taken pursuant hereto, to the extent not otherwise governed by the laws of the United States, shall be governed by the laws of the State of Washington without giving effect to principles of conflicts of law. Participants irrevocably consent to the nonexclusive jurisdiction and venue of the state and federal courts located in the State of Washington.

The granting of Awards and the issuance of shares of Common Stock under the Plan are subject to all applicable laws, rules and regulations and to such approvals by any governmental agencies or national securities exchanges as may be required, whether located in the United States or a foreign jurisdiction.

The effective date (the “Effective Date”) is the date on which the Plan is approved by the stockholders of the Company.
