POTLATCH CORPORATION SALARIED SUPPLEMENTAL BENEFIT PLAN II Effective December 5, 2008 Amended and Restated as of February 14, 2014 POTLATCH CORPORATION SALARIED SUPPLEMENTAL BENEFIT PLAN II Effective December 5, 2008 Amended and Restated as of February 14, 2014

SECTION 1. INTRODUCTION.

(a)The Potlatch Corporation Salaried Supplemental Benefit Plan II (the “Plan”) was established effective December 5, 2008. This amendment and restatement incorporates changes to the Plan effective February 14, 2014. The purposes of the Plan include:

(i) to supplement benefits provided under the Retirement Plan to the extent such benefits are reduced due to the limits of Section 401(a)(17) or 415 of the Code;

(ii) to provide retirement benefits that take into account deferred Incentive Plan awards;

(iii) to provide retirement benefits to certain executives calculated as if they received a standard bonus award under the Incentive Plan; and

(iv) to supplement benefits provided under the 401(k) Plan to the extent that a participant’s allocations of Company Contributions or Allocable Forfeitures are reduced due to the limits of Section 401(a)(17), 401(k)(3), 401(m) or 415 of the Code or because the participant has deferred an Incentive Plan award.

(b)This Plan is a successor plan to the Potlatch Forest Products Salaried Employees’ Supplemental Benefit Plan II (the “PFPC Plan”), with respect to those individuals identified as “Potlatch Employees” pursuant to the Employee Matters Agreement by and between Potlatch Corporation and Clearwater Paper Corporation (the “EMA”). Pursuant to the EMA, all accrued benefit liabilities under the PFPC Plan with respect to Potlatch Employees have been transferred to and assumed by this Plan.

(c)This Plan also is a successor plan to the Potlatch Corporation Salaried Employees’ Supplemental Benefit Plan (the “Prior Plan”). Effective December 31, 2004, the Prior Plan was frozen and no new benefits are to accrue under it; provided, however, that any benefits accrued and vested under the Prior Plan before January 1, 2005 continue to be governed by the terms and conditions of the Prior Plan as in effect on December 31, 2004 or on the date of any later amendment, provided that such amendment is not a material modification of the Prior Plan under Section 409A.

(d)Any benefits that accrued under the Prior Plan with respect to Potlatch Employees before January 1, 2005 but that were unvested after December 31, 2004 and any benefits that accrued under the Prior Plan after December 31, 2004 are deemed to have accrued under this Plan and all such accruals are governed by the terms and conditions of this Plan as it may be amended from time to time.

(e) This Plan is intended to be a deferred compensation plan, for the benefit of a select group of management or highly compensated employees of the Company, and, as such, to be exempt from all of the provisions of Parts 2, 3, and 4 of Title I of ERISA. The Company intends that the existence of a trust, if any, will not alter the characterization of the Plan as “unfunded” for purposes of ERISA, and will not be construed to provide income to the Participants under the Plan prior to actual payment of the vested accrued benefits hereunder.

(f)The Plan is intended to comply with the requirements of Section 409A. Notwithstanding any other provision of the Plan to the contrary, the Plan shall be interpreted, operated and administered in a manner consistent with such intentions. 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 so that any payment qualifies for exemption from or complies with Section 409A; provided, however, that the Committee makes no representations that payments under the Plan shall be exempt from or comply with Section 409A and makes no undertaking to preclude Section 409A from applying to payments under the Plan.

(g)Capitalized terms used in the Plan (other than those defined in Section 2) shall have the same meanings given to such terms in the Retirement Plan or the 401(k) Plan, as the context may require.

Participation in the Plan shall be limited to:

(a)All participants in the Retirement Plan whose benefits thereunder are reduced due to the limits of Section 401(a)(17) of the Code (limiting the amount of compensation that may be taken into account under the Retirement Plan) or Section 415 of the Code (limiting the annual benefits payable under the Retirement Plan);

(c)All participants in the Retirement Plan who otherwise participate in the Incentive Plan, who are officers of the Company and who are required by company policy to retire no later than the Normal Retirement Date; and

(d)All participants in the 401(k) Plan whose allocations of the Company Contributions or Allocable Forfeitures are reduced because the participant has deferred an Incentive Plan award or because of the limits of one or more of the following sections of the Code:

(i) Section 401(a)(17) (limiting the amount of compensation that may be taken into account under the 401(k) Plan);

(iii) Section 401(m) (limiting participants’ Non-deferred Contributions and matching Company Contributions under the 401(k) Plan); or

Any Employee with whom the Company has entered into a contract that provides benefits equivalent to any of the benefits described in this Plan shall not be eligible to participate in or receive benefits under this Plan to the extent of such equivalent benefits.

SECTION 4. AMOUNT OF PLAN BENEFITS.

A Participant’s Plan Benefit shall consist of (to the extent applicable to the Participant) (i) the Retirement Plan Supplemental Benefit and (ii) the 401(k) Plan Supplemental Benefit. All Plan Benefits shall accrue as of the last day of each Plan Year or as of the date, if earlier, on which the Participant Separates from Service.

(a)Retirement Plan Supplemental Benefit. A Participant’s Retirement Plan Supplemental Benefit shall be the amount determined under Section 4(a)(i) minus the amount determined under Section 4(a)(ii).

(i) All Participants. A Participant’s Retirement Plan Supplemental Benefit shall be the difference between

(A) the actual vested benefits payable under the Retirement Plan to the Participant and his or her joint annuitant (if any) and

(B) the vested benefits that would be payable under the Retirement Plan if (i) the limitations imposed by sections 401(a)(17) and 415 of the Code did not apply, (ii) any deferred Incentive Plan award credited to the Participant had been paid to the Participant in the year it was deferred and (iii) any benefits payable under Appendix H of the Retirement Plan were not included.

In the case of any Participant who is an officer of the Company and who is required by the corporate mandatory retirement policy to retire no later than the mandatory retirement date, the Retirement Plan Supplemental Benefit also shall include the difference, if any, between the amount determined in Section 4(a)(i)(B) and the vested benefits that would be payable under the Retirement Plan if modified as in Section 4(a)(i)(B) and also

modified so that the Incentive Plan awards credited to the Participant (both deferred and not deferred) which were recognized by the Retirement Plan in the Participant’s Final Average Earnings had been 100% of the Standard Bonus (as defined in the Incentive Plan), considering for this purpose, only those years during which the Participant was an officer of the corporation and was required to retire not later than the mandatory retirement date under the corporate mandatory retirement policy; provided, however, that for individuals who retire in an Award Year beginning on or after January 1, 2007, the Standard Bonus will be used to calculate Final Average Earnings only with respect to periods prior to January 1, 2007.

(ii) Prior Plan Offsets. A Participant’s Retirement Plan Supplemental Benefit shall be reduced by the Participant’s retirement plan supplemental benefit accrued under the Prior Plan.

The Participant shall become vested in the Participant’s Retirement Plan Supplemental Benefit upon the completion of five Years of Vesting Service.

(b)401(k) Plan Supplemental Benefit. A Participant’s 401(k) Plan Supplemental Benefit shall be the vested amount credited to a bookkeeping account established pursuant to this Section 4(b). As of the last day of each Plan Year commencing after December 31, 2004, each Participant whose allocations for such Plan Year under the 401(k) Plan are reduced as described in Section 3(d) and who has made the maximum Participating Deferred and Participating Non-deferred Contributions permitted under the 401(k) Plan for such Plan Year shall have an amount credited to such bookkeeping account. The amount so credited shall be the difference between the amount of Company Contributions and Allocable Forfeitures actually allocated to the Participant under the 401(k) Plan for such Plan Year and the amount of Company Contributions and Allocable Forfeitures that would have been allocated to the Participant under the 401(k) Plan for such Plan Year if the Participant had made Participating Contributions equal to six percent of the Participant’s Earnings (determined without regarding to Section 401(a)(17) of the Code and without regard to the deferral of any Incentive Plan award otherwise payable).

Through December 31 of the Plan Year preceding the Plan Year in which payment of the Participant’s entire 401(k) Plan Supplemental Benefit is made, the amount credited to such bookkeeping account shall be credited with earnings and losses based on the following:

(i)    For periods prior to January 1, 2009, earnings shall be calculated using an interest rate equal to 70% of the higher of the following averages, compounded annually: (i) the prime rate charged by the major commercial banks as of the first business day of each month (as reported in an official publication of the Federal Reserve System) or (ii) the average monthly long-term rate of A-rated corporate bonds (as published in Moody’s Bond Record).

(ii)    For periods on and after January 1, 2009 and prior to the date determined under Section 4(b)(iii), earnings shall be calculated using an interest rate equal to 120% of the long-term applicable federal rate, with quarterly compounding, as published under Section 1274(d) of the Code for the first month of each calendar quarter.

(iii)    Effective as soon as practicable after January 1, 2009 as determined by the Committee, for Participant groups identified by the Committee, earnings and losses shall be calculated by reference to the rate of return on one or more of the investment alternatives that are available under the 401(k) Plan and which are designated by the Committee as available under this Plan. Each Participant may select (in ten percent (10%) increments) which investment alternative(s) will be used for this purpose with respect to his or her bookkeeping account, and the alternative(s) selected need not be

the same as the Participant has selected under the 401(k) Plan, but any such selection will apply only prospectively. The Committee shall determine how frequently such selections may be changed.

The Participant shall become vested in the Participant’s 401(k) Plan Supplemental Benefit upon the earliest of completion of two Years of Vesting Service, attainment of age 65 while an Employee, death while an Employee or Total and Permanent Disability.

SECTION 5. DISTRIBUTIONS OF PLAN BENEFITS.

Distributions of Plan Benefits shall be made after the Participant Separates from Service pursuant to the following procedures.

(a)Retirement Plan Supplemental Benefit. The Retirement Plan Supplemental Benefits shall be distributed beginning no later than 90 days following the Participant’s attainment of age 55 or Separation from Service, whichever is later (the “Beginning Date”). If the Participant’s benefit is less than or equal to $50,000 (calculated as an Actuarial Equivalent lump sum of the amount payable at Normal Retirement) on the Beginning Date, the Participant’s benefit shall be paid in a lump sum. If the Participant’s benefit is greater than $50,000 (calculated as an Actuarial Equivalent lump sum of the amount payable at Normal Retirement) on the Beginning Date, the Participant’s benefit shall be paid in the form of an annuity. The Participant may elect the form of annuity payment from the forms available under the Retirement Plan, excluding the Social Security Adjustment option, not more than 30 days after the Beginning Date. A Participant’s Retirement Plan Supplemental Benefit which is paid in the form of annuity shall be subject to the same actuarial adjustments for form of payment applicable to Retirement Plan benefits. If a Participant’s Retirement Plan Supplemental Benefit is payable before the Participant is first eligible to receive benefits under the Retirement Plan, the Retirement Plan Supplemental Benefit will be calculated to be the Actual Equivalent of the amount payable at Normal Retirement.

If the Participant fails to make an annuity election pursuant to this Section 5(a), the vested Retirement Supplemental Benefit shall be distributed in the form of Joint & Survivor 50% Annuity or Single Life Annuity if the Participant is unmarried.

(b)401(k) Plan Supplemental Benefit. By the later of (i) January 31st of the calendar year immediately following the first calendar year in which the Participant first accrues a benefit under this Plan (or if earlier, thirty 30 days after first becoming eligible to participate in the Potlatch Corporation Management Deferred Compensation Plan), or (ii) to the extent authorized by the Committee, December 31, 2008, each Participant shall elect to receive distribution of the Participant’s vested 401(k) Plan Supplemental Benefit in ten or fewer annual installments or in a lump sum beginning in the Plan Year (but no later than March 15^th of such Plan Year) following the Plan Year in which the Participant Separates from Service by filing the prescribed form with the Company. This election shall be irrevocable. Distribution will be made in accordance with the Participant’s election except as provided below. The amount of any annual installment shall be determined by dividing the amount credited to the Participant’s bookkeeping account as of the last day of the Plan Year preceding the date of distribution of such installment by the total number of installments elected by the Participant less the number of installments already paid. For purposes of the Plan, installment payments shall be treated as a single distribution under Section 409A. All annual installment payments shall be payable no later than March 15^th of the payment year.

If the Participant fails to make an election pursuant to this Section 5(b), the vested 401(k) Plan Supplemental Benefit shall be distributed in a lump sum in the Plan Year (but no later than March 15^th of such Plan Year) following the Plan Year in which the Participant Separates from Service.

If a Participant dies before the Participant’s 401(k) Plan Supplemental Benefit has been completely distributed, such remaining benefit shall be distributed in a lump sum as soon as practicable thereafter to the Beneficiary. If the designated Beneficiary does not survive the Participant or dies before receiving payment in full of the Participant’s Deferred Compensation Account, payment shall be made to the estate of the last to die of the Participant or the designated Beneficiary.

Notwithstanding the foregoing, a lump sum distribution shall be made in the Committee’s (or its delegate’s) discretion to clear out a small balance held for the benefit of the Participant (or his or her Beneficiary) provided that the Committee’s (or its delegate’s) decision is evidenced in writing prior to the date of the distribution, the distribution is not greater than the applicable dollar amount under Section 402(g)(1)(B) of the Code and the payment results in the termination of all benefits due under the plan and all other “account balance plans” treated as a single nonqualified deferred compensation plan with this Plan under Treasury Regulation Section 1.409A-1(c)(2).

To the extent that no bookkeeping account has previously been established for a Participant and if the amount to be credited to the Participant’s account is less than $1,000 in a Plan year, then no 401(k) Plan Supplement Benefit bookkeeping account shall be established for the Participant in such Plan Year and the deferred amount shall be distributed to the Participant in cash not later than the end of the Plan Year following the Plan Year in which such amount was deferred.

(c)Delayed Distribution to Key Employees. Notwithstanding any other provision of this Section 5, distributions of the Retirement Plan Supplemental Benefit and the 401(k) Plan Supplemental Benefit accounts made to a Participant who is identified as a Key Employee at the time of his or her Separation from Service will be delayed for a minimum of six months if the Participant’s distribution is triggered by his or her Separation from Service. Any payment that otherwise would have been made pursuant to this Section 5 during such six-month period will be made in one lump sum payment, without adjustment for interest, not later than the last day of the second month following the month that is six months from the date the Participant Separates from Service. The determination of which Participants are Key Employees will be made by the Company in its sole discretion in accordance with this Section 5(c) and section 416(i) of the Code, including regulations and guidance promulgated thereunder (defining key employees), and Section 409A.

(d)No Acceleration of Benefits. Notwithstanding any other provision of the Plan to the contrary, no distribution shall be made from the Plan that would constitute an impermissible acceleration of payment as defined in Section 409A(a)(3).

SECTION 6. MISCELLANEOUS

(a)Forfeitures. Plan Benefits shall be forfeited under the following circumstances:

(i) If the Participant is not vested in the Retirement Plan Supplemental Benefit or 401(k) Plan Supplemental Benefit when the Participant Separates from Service; or

(ii) If the Participant is indebted to the Company or any affiliate at the time the Participant or the Participant’s joint annuitant or other Beneficiary becomes entitled to payment of a Plan Benefit. In such a case, to the extent that the amount of the Plan Benefit does not exceed such indebtedness, the amount of such Plan Benefit shall be forfeited and the Participant’s indebtedness shall be extinguished to the extent of such forfeiture.

(b)Funding. The interest under the Plan of any Participant and such Participant’s right to receive a distribution from the Plan shall be an unsecured claim against the general assets of the Company. Until distributed, Plan Benefits shall be bookkeeping entries only and no Participant shall have an interest in or claim against any specific asset of the Company pursuant to the Plan. Notwithstanding the foregoing, the Company may, in its discretion, choose to contribute to the Potlatch Corporation Benefits Protection Trust Agreement to assist with the payment of benefits under the Plan.

(c)Tax Withholding. The Company shall make or cause to be made appropriate arrangements for satisfaction of any federal or state income tax or other payroll-based withholding tax required to be paid by the Participant upon the accrual or payment of any Plan Benefits.

(d)No Employment Rights. Nothing in the Plan shall be deemed to give any individual a right to remain in the employ of the Company or any subsidiary or to limit in any way the right of the Company or a subsidiary to terminate any individual’s employment with or without case, which right is hereby reserved.

(i) Except as otherwise provided in Section 6(a)(ii) with respect to a Participant’s indebtedness to the Company or an Affiliate or in Section 6(e)(ii), the interest or rights of any person in the Plan or in any distribution to be made hereunder shall not be assigned (either at law or in equity), alienated, anticipated or subject to the attachment, bankruptcy, garnishment, levy, execution or other legal or equitable process. Any act in violation of this Section 6(e)(i) shall be void.

(ii) All or any portion of a Participant’s Plan Benefit hereunder shall be subject to the creation, assignment or recognition of a right under a state domestic relations order that is determined to be a “qualified domestic relations order” (within the meaning of Section 414(p) of the Code) under the procedures established by the Company for the determination of the qualified status of domestic relations orders and for making distributions under qualified domestic relations orders.

(f)Administration. The Plan shall be administered by the Committee. The Committee (or its delegate) shall make such rules, interpretations and computations as it may deem appropriate, and any decision of the Committee (or its delegate) with respect to the Plan, including (without limitation) any determination of eligibility to participate in the Plan and any calculation of Plan Benefits, shall be conclusive and binding on all persons.

(i) The Company expects to continue the Plan indefinitely. Future conditions, however, cannot be foreseen, and the Committee shall have the authority to amend or to terminate the Plan at any time. Notwithstanding the foregoing, the Vice President, Human Resources, of the Company shall have the power and authority to amend the Plan provided that such amendment (i) does not materially increase the cost of the Plan to the Company or (ii) is required to comply with new or changed legal requirements applicable to the Plan, including, but not limited to, Section 409A.

(ii) In the event of an amendment of the Plan, a Participant’s Plan Benefits shall not be less than the Plan Benefits to which the Participant would be entitled if the Participant had Separated from Service immediately prior to such amendment. In addition to the foregoing, the Plan may not be amended (including any amendment to this Section 6(g))

or terminated during the three-year period following a Change in Control if such amendment or termination would alter the provisions of this Section 6(g) or adversely affect a Participant’s accrued Plan Benefits.

(iii) Except as provided in Section 6(g)(iv), in the event of termination of the Plan, the Participants’ Plan Benefits may, in the Committee’s discretion, be distributed within the period beginning 12 months after the date the Plan was terminated and ending 24 months after the date the Plan was terminated, or pursuant to Section 5, if earlier. If the Plan is terminated and the Plan Benefits are distributed, the Company, in compliance with Section 409A shall terminate all account and non-account balance non-qualified deferred compensation plans with respect to all Participants and shall not adopt a new account or non-account balance non-qualified deferred compensation plan for at least five years after the date the Plan was terminated.

(iv) The Committee may terminate the Plan upon a corporate dissolution of the Company that is taxed under section 331 of the Code or with the approval of a bankruptcy court pursuant to 11 U.S.C. Section 503(b)(1(A), provided that the Plan Benefits are distributed and included in the gross income of the Participants by the latest of (A) the Plan Year in which the Plan terminates or (B) the first Plan Year in which payment of the Plan Benefits is administratively practicable.

(h)Successors and Assigns. The Plan shall be binding upon the Company, its successors and assigns, and any parent corporation of the Company’s successors or assigns. Notwithstanding that the Plan may be binding upon a successor or assign by operation of law, the Company shall require any successor or assign to expressly assume and agree to be bound by the Plan in the same manner and to the same extent that the Company would be if no succession or assignment had taken place.

(i) Informal Resolution of Questions. Any Participant who has questions or concerns about his or her benefits under the Plan is encouraged to communicate with the Vice President, Human Resources, of the Company. If this discussion does not give the Participant satisfactory results, a formal claim for benefits may be made within one year of the event giving rise to the claim in accordance with the procedures of this Section 6(i). If a Participant fails to file a formal claim within the preceding limitation period, the Participant shall not be entitled to bring any legal or equitable action for benefits under the Plan.

(ii) Formal Benefits Claim – Review by Benefits Committee. A Participant may make a written request for review of any matter concerning his or her benefits under the Plan. The claim must be addressed to the Benefits Committee, Salaried Supplemental Benefit Plan II, Potlatch Corporation, 601 W. First Avenue, Suite 1600, Spokane, Washington 99201. The Benefits Committee shall decide the action to be taken with respect to any such request and may require additional information if necessary to process the request. The Benefits Committee shall review the request and shall issue its decision, in writing, no later than 90 days after the date the request is received, unless the circumstances require an extension of time. If such an extension is required, written notice of the extension shall be furnished to the person making the request within the initial 90-day period, and the notice shall state the circumstances requiring the extension and the date by which the Benefits Committee expects to reach a decision on the request. In no event shall the extension exceed a period of 90 days from the end of the initial period.

(iii) Notice of Denied Request. If the Benefits Committee denies a request in whole or in part, he shall provide the person making the request with written notice of the denial within the period specified in Section6(i)(ii). The notice shall set forth the specific reason for the denial, reference to the specific Plan provisions upon which the denial is based, a description of any additional material or information necessary to perfect the request, an explanation of why such information is required, and an explanation of the Plan’s appeal procedures and the time limits applicable to such procedures, including a statement of the claimant’s right to bring a civil action under section 502(a) of ERISA following an adverse benefit determination to review.

The appeal must be addressed to the Benefits Committee, Salaried Employees’ Supplemental Benefit Plan II, Potlatch Corporation, 601 W. First Avenue, Suite 1600, Spokane, Washington 99201.

(B) The Benefits Committee’s review shall take into account all comments, documents, records and other information submitted by the appellant relating to the claim, without regard to whether such information was submitted or considered in the initial benefit determination. The Benefits Committee’s review shall not be restricted to those provisions of the Plan cited in the original denial of the claim.

(C) The Benefits Committee shall issue a written decision within a reasonable period of time but not later than 60 days after receipt of the appeal, unless special circumstances require an extension of time for processing, in which case the written decision shall be issued as soon as possible, but not later than 120 days after receipt of an appeal. If such an extension is required, written notice shall be furnished to the appellant with the initial 60-day period. This notice shall state the circumstances requiring the extension and the date by which the Benefits Committee expects to reach a decision on the appeal.

(D) If the decision on the appeal denies the claim in whole or in part written notice shall be furnished to the appellant. Such notice shall state the reason(s) for the denial, including references to specific Plan provisions upon which the denial was based. The notice shall state that the appellant is entitled to receive, upon request and free of charge, reasonable access to, and copies of, all documents, records and other information relevant to the claim for benefits.

Except as provided in this amendment and restatement to Addendum A, all of the terms and conditions of the Potlatch Corporation Salaried Supplemental Benefits Plan II, or successor plan (the “Plan”), shall apply to any benefit payable under the Plan to Michael J. Covey. Potlatch Corporation (“Potlatch”) provided to Mr. Covey a minimum pension benefit guaranteed in his Employment Agreement dated February 6, 2006, as amended (the “Agreement”), which term ends on February 6, 2009, if he retires at or after age 55. The Agreement provides that Potlatch is obligated to continue to honor the retirement benefits set forth in Section 5(b)(iv) of the Agreement described below after the term of the Agreement ends. In addition, the amendment to the Agreement provides that Mr. Covey is fully vested in his Plan benefits, but not the minimum pension benefit provided in Section 5(b)(iv) of his Agreement, as of his first day of employment, which is consistent with the vesting of benefits provided to other Potlatch executives; provided, however, in the event of a Change in Control, as defined in the Plan, he will be vested in the minimum pension benefit immediately. This amended and restated Addendum A describes the benefits that will be provided to Mr. Covey under the Plan.

Michael J. Covey shall be fully vested in the Plan, except for the “Minimum Benefit” described below, on the first day of employment with Potlatch. Furthermore, if Mr. Covey Separates from Service, as defined in the Plan, at or after age 55, he will receive a Minimum Benefit under the Plan, determined as follows:

(a)    The positive amount equal to $26,800 minus the Total Monthly Pension Benefits, as defined below (the “Difference”), shall be paid to Mr. Covey as provided herein.

(i)    The “Total Monthly Pension Benefits” shall be the sum of the monthly vested benefit under the Company’s Plan and qualified pension plan, as described in Section 4(a)(i)(B) of the Plan (the “Company Pension Benefits”), plus the monthly benefit under Mr. Covey’s former employer’s supplemental pension plan and qualified pension plan that would have been provided to Executive, taking into consideration his termination date with his former employer (the “Former Company Pension Benefits”); provided that the Company Pension Benefits and the Former Company Pension Benefits shall be calculated as the actuarial equivalent of a single life annuity.

(b)    The payment of the Difference as a monthly single life annuity shall be converted at the Beginning Date, as defined in the Plan, into the actuarial equivalent form that Executive has validly elected to receive his Retirement Plan Supplemental Benefit under the Plan, which amount shall be paid at the same time and in the same form as his Retirement Plan Supplemental Benefit.

(c)    In the event that the Difference is zero or less, then no additional benefits shall be paid to Mr. Covey hereunder.

Notwithstanding the foregoing, if there is a Change in Control, as defined in the Plan, then Mr. Covey shall immediately vest in his Minimum Benefit and he shall receive his Minimum Benefit upon his Separation from Service without regard to attainment of age 55.

Except as provided in this Addendum B, all of the terms and conditions of the Potlatch Corporation Salaried Supplemental Benefits Plan II (the “Plan”) shall apply to any benefit payable under the Plan to Brent Stinnett.
