Potlatch Corporation Management Deferred Compensation Plan



 Exhibit (10)(x) 
 POTLATCH CORPORATION 
 MANAGEMENT DEFERRED COMPENSATION PLAN 
 Effective June 1, 2008 
 Amended and Restated as of May 1, 2009 







 1. ESTABLISHMENT AND PURPOSE 
 (a) The Potlatch Corporation Management Deferred Compensation Plan was adopted on May 16, 2008, by the Board of Directors of Potlatch Corporation to provide an opportunity for senior management who have made
the maximum elective contributions permitted under the 401(k) Plan to elect to defer additional compensation and to invest and accumulate such compensation on a tax-deferred basis. This restatement incorporates changes to the Plan effective
May 1, 2009. 
 (b) This Plan is also intended to provide the rules and regulations for deferral of awards under the Potlatch
Corporation Management Performance Award Plan II (“MPAP II”) for the 2008 performance period and under the Potlatch Corporation Annual Incentive Plan (the “AIP”) beginning with the 2009 performance period. 
 (c) Effective as of October 1, 2008, this Plan also provides the rules and regulations for the administration of deferrals previously made under
the MPAP II. For avoidance of doubt, deferrals made under the Potlatch Corporation Management Performance Award Plan, which are not subject to Section 409A of the Code, continue to be subject to the rules of that plan and the administrative
rules and regulations applicable thereto. 
 (d) Pursuant to the Employee Matters Agreement by and between Potlatch Corporation and
Clearwater Paper Corporation (the “EMA”), all deferred compensation liabilities with respect to “Clearwater Employees” (as defined in the EMA) under this Plan, the MPAP II and the Potlatch Corporation Management Performance Award
Plan have been transferred to and assumed by the Clearwater Paper Corporation Management Deferred Compensation Plan (the “Clearwater Plan”). Deferral and payment elections made by Clearwater Employees under this Plan and the MPAP II shall
be given effect under the Clearwater Plan. 
 (e) The provisions of this Plan for elections to defer base salary are effective for base
salary earned on or after January 1, 2009. 
 (f) The Plan is intended to comply with the requirements of Section 409A of the
Code. The Plan is intended to constitute an unfunded program for the benefit of a select group of management or highly compensated employees of ERISA, and, as such, to be exempt from all of the provisions of Parts 2, 3, and 4 of Title I of ERISA.

 2. DEFINITIONS

 (b) “AIP” means the Potlatch Corporation Annual Incentive Plan and any successor plan thereto. 
 (c) “Beneficiary” means the person or persons who become entitled to receive payment of the Participant’s Deferred Compensation Account as a result of the death of the Participant. A Participant’s designated beneficiary
under the 401(k) Plan shall be the Participant’s Beneficiary under this Plan.

 (h) “Corporation” means Potlatch Corporation, a
Delaware corporation. 
 (i) “Deferred Compensation Account” means the bookkeeping account established pursuant to
Section 6 on behalf of each Employee who elects to participate in the Plan. Within a Participant’s Deferred Compensation Account, a Directed Investment Account, Stock Unit Account, Holding Account, and appropriate sub-accounts shall be
maintained as are necessary for the proper administration of a Participant’s Deferred Compensation Account. An Employee who has made a deferral under the MPAP II shall be deemed to have elected to participate in this Plan. 
 (j) “Disabled” means an Employee is unable to engage in any substantial gainful activity by reason of any medically determinable physical or
mental impairment which can be expected to result in death or can be expected to last for a continuous period of not less than twelve months. 
 (k) “Dividend Equivalent” means an amount equal to the cash distribution paid on an outstanding share of the Corporation’s common stock. Dividend Equivalents shall be credited with respect to Stock Units as if each Stock Unit
were an outstanding share of the Corporation’s common stock, except that Dividend Equivalents shall also be credited with respect to fractional Stock Units. 
 (l) “ERISA” means the Employee Retirement Income Security Act of 1974, as amended.

 3 








 (p) “MPAP II” means the Potlatch Corporation Management Performance Award Plan II, as
amended. 
 (q) “Participant” means an Employee who has deferred Compensation credited to a Deferred Compensation Account under
the Plan. 
 (r) “Performance-Based Compensation” means compensation the amount of which, or the entitlement to which, is
contingent on the satisfaction of preestablished organizational or individual performance criteria relating to a performance period of at least twelve (12) consecutive months. Organizational or individual performance criteria are considered
preestablished if established in writing by not later than ninety (90) days after the commencement of the period of service to which the criteria relates, provided that the outcome is substantially uncertain at the time the criteria are
established. Performance-Based Compensation does not include any amount or portion of any amount that will be paid either regardless of performance, or based upon a level of performance that is substantially certain to be met at the time the
criteria is established. Compensation may be Performance-Based Compensation where the amount will be paid regardless of satisfaction of the performance criteria due to the Employee’s death, disability, or a Change in Control Event (as defined
in Treasury Regulation Section l.409A-3(i)(5)), provided that a payment made under such circumstances without regard to the satisfaction of the performance criteria will not constitute performance-based compensation. For this purpose, a disability
refers to any medically determinable physical or mental impairment resulting in the Employee’s inability to perform the duties of his or her position or any substantially similar position, where such impairment can be expected to result in
death or can be expected to last for a continuous period of not less than six months. Performance-Based Compensation may include payments based upon subjective performance criteria, provided that: (i) the subjective performance criteria are
bona fide and relate to the performance of the Employee, a group of service providers that includes the Employee, or a business unit for which the Employee provides services (which may include the entire organization); and (ii) the
determination that any subjective performance criteria have been met is not made by the Employee or a family member of the Employee (as defined in Section Code 267(c)(4) applied as if the family of an individual includes the spouse of any member of
the family), or a person under the effective control of the Employee or such a family member, and no amount of the compensation of the person making such determination is effectively controlled in whole or in part by the Employee or such a family
member. 
 (s) “Plan” means the Potlatch Corporation Management Deferred Compensation Plan. 
 (t) “Plan Year” means the 12-month period beginning January 1 and ending December 31. 
 (u) “Separation from Service” means termination of an Employee’s service as an Employee consistent with Section 409A of the Code
and the regulations promulgated thereunder. For purposes of the Plan, “Separation from Service” generally means termination of an Employee’s employment as a common-law employee of the Corporation and each Affiliate of the Corporation.
A Separation from Service will not be deemed to have occurred if an Employee continues to provide services to the Corporation or an Affiliate in a capacity other than as an

  

 4 








 
employee and if the former employee is providing a level of bona fide services that is fifty percent (50%) or more of the average level of services rendered during the immediately preceding
thirty-six (36) months of employment with the Corporation or Affiliate; provided, however, that a Separation from Service will be deemed to have occurred if it is reasonably anticipated that an Employee’s service with the Corporation and
its Affiliates will terminate after a certain date or the level of bona fide services that the Employee will perform after such date (whether as an employee or another capacity) will permanently reduce to a rate that is less than twenty percent
(20%) of the bona fide level of services rendered, on average, during the immediately preceding thirty-six (36) months (or if employed by the Corporation and its Affiliates less than thirty-six (36) months, such lesser period).
However, the employment relationship is treated as continuing intact while the individual is on military leave, sick leave, or other bona fide leave of absence if the period of such leave does not exceed six months, or if longer, so long as the
individual’s right to reemployment with the service recipient is provided either by statute or by contract. If the period of leave exceeds six months and the individual’s right to reemployment is not provided either by statute or by
contract, the employment relationship is deemed to terminate on the first date immediately following such six-month period. 
 (v)
“Stock Units” means the deferred portion of Compensation which is converted into a unit denominated in shares of the Corporation’s common stock. 
 (w) “Value” means the closing price of the Corporation’s common stock as reported in the New York Stock Exchange, Inc., composite transactions reports for the relevant date. 
 (x) “Variable Fractions Method” is a distribution method for amounts payable in installments. The amount of the first installment is
determined by dividing the Participant’s account balance by the total number of installments due. Each subsequent annual installment is equal to the Participant’s account balance as adjusted for earnings or losses since the last
distribution date divided by a denominator equal to the total number of installments due minus the number of installments previously paid. 
 (y) “Year” shall mean the calendar year. 
 3. ELIGIBILITY TO MAKE DEFERRALS 
 (a) Each Employee who is in a position that is eligible for Long-Term Incentive awards (an “Eligible Employee”) and who has made the maximum
elective deferrals under Section 402(g) of the Code or the maximum elective contributions permitted under the terms of the 401(k) Plan shall be eligible to elect to defer base salary under the Plan. 
 (b) Each Eligible Employee who is eligible to receive an award under the MPAP II or AIP (other than an award under an AIP Special Awards Fund) shall
be eligible to defer such award under the Plan; provided that, an Employee who is required to defer his or her award shall automatically become a participant in this Plan. 
  


 5 








 4. PARTICIPATION 
 (a) Each Employee who is eligible to participate in the Plan pursuant to Section 3 above shall, prior to the beginning of each Year and in accordance with the applicable deadline established by the Committee,
have the option to make an irrevocable election to defer a percentage of his or her Compensation earned during the following Year before the beginning of each such Year. Compensation paid after December 31 of a Plan Year for services performed
by the Employee during the final payroll period of the calendar year and which payroll period includes the last day of such calendar year shall be treated as earned for services performed in the year paid. 
 (b) Notwithstanding the foregoing, an Employee may make an irrevocable election to participate during a Year with respect to Compensation earned
during that Year and subsequent to the filing of such election, provided such election is made within thirty (30) days of the Employee’s initial eligibility to participate in this Plan and any other nonqualified deferred compensation plans
treated as a single plan with this Plan under Section 409A of the Code. Any such initial election shall apply only to Compensation earned for services performed after the date of the election. If compensation is due for services performed over
a period of time which includes the period both before and the period after the date of the election, the election will apply to an amount equal to the total amount of the compensation paid for such performance period multiplied by the ratio of the
number of days remaining in the performance period after the election over the total number of days in the performance period. 
 (c)
Notwithstanding the preceding rules, a deferral election for an award of Compensation under the MPAP II or AIP, which constitutes Performance-Based Compensation, may be made no later than six months before the end of such performance period. This
special election rule is available only if (i) the Employee performs services for the Company or its Affiliate continuously from the later of the beginning of the performance period or the date the performance criteria are established through
the date an election is made with respect to such payment, (ii) the election is made before the amount of the Performance-Based Compensation to be received becomes reasonably ascertainable or, if the Performance-Based Compensation is a
specified or calculable amount, when the amount is substantially certain to be paid, and (iii) the performance period is at least twelve (12) months in duration. 
 (d) The Committee may also adopt such additional or alternative election rules provided that such rules comply with the rules of Section 409A of
the Code and applicable regulatory authority. 
 5. DEFERRAL ELECTIONS 
 (a) An Employee who elects to participate in the Plan with respect to annual base salary or an award under the MPAP II or AIP for a Year shall file a
deferral election with respect to each type of Compensation on such form as the Committee shall prescribe, which shall indicate: 
 (i)
The amount or percentage of each type of Compensation that such Employee elects to defer pursuant to the terms of the Plan. The percentage must be in increments

  

 6 








 
of ten percent (10%) and may not exceed fifty percent (50%) in the case of annual base salary. An election to voluntarily defer an award under the MPAP II or AIP must be in increments
of ten percent (10%) and shall be for not less than fifty percent (50%) of such award. Notwithstanding the foregoing, an election to defer Compensation may not reduce the Employee’s remaining compensation below the amount necessary to
satisfy applicable employment tax withholding, income tax withholding, and benefit plan withholding. This election shall be irrevocable with respect to each type of Compensation for that Year to which it applies after the applicable deadline for
making such election as provided in Section 4 for that Year. 
 (ii) The percentage of the Compensation deferred pursuant to the
election that is to be converted into Stock Units or deemed invested in any other investment account available under Section 7. 
 (b) An Employee who elects to participate in the Plan shall have only one form of payment election in effect for all amounts deferred under the Plan. Subject to Section 5(c), below, at the time of an Employee’s initial election to
defer base salary or an award under the MPAP II or AIP, the Employee shall file an election and shall indicate whether the deferred Compensation shall be paid in a lump sum or paid in annual installments over a period of fifteen (15) or fewer
years. For purposes of the Plan, installment payments shall be treated as a single distribution for purposes of Section 409A of the Code. Deferred Compensation shall be distributed in a single lump sum payment unless the Employee elects
otherwise. 
 (c) An Employee’s election as to the time and form of payment of deferred Compensation shall be irrevocable and binding
on all deferred Compensation under the Plan. For avoidance of doubt it is intended that a Participant shall have only one method of payment in effect. 
 (d) For purposes of determining the payment election in effect for a Participant with existing deferrals under this Plan prior to May 1, 2009 or under the MPAP II, the payment election in effect as of
April 30, 2009 shall remain in effect for all existing and future deferrals under the Plan. 
 6. ESTABLISHMENT OF DEFERRED ACCOUNTS

 (a) For each Employee who has deferred compensation under the MPAP II or AIP or who has elected to defer base salary, the Corporation
shall establish a Deferred Compensation Account to which shall be credited an amount equal to that portion of the Compensation which would have been payable currently to the Employee but for the terms of the deferral election. 
 (b) If the deferral election includes an election to convert a percentage of the Compensation deferred pursuant to the election into Stock Units, the
number of full and fractional Stock Units shall be determined as follows: 
 (i) For an award deferred under the MPAP II, such conversion
shall be made in accordance with Section 9(c) of the MPAP II. 
  

 7 








 (ii) Any amount of base salary or AIP award that is deferred under this Plan and with respect to which
the Employee has elected to allocate to Stock Units shall be accumulated in the Holding Account. The balance of the Holding Account shall be converted into full and fractional Stock Units and transferred to a Stock Unit Account on a quarterly basis
as of the last trading day of each calendar quarter by dividing the balance of the Holding Account by the Value of the Corporation’s common stock on such crediting date. 
 (c) Amounts credited to a Participant’s Deferred Compensation Account shall be fully vested at all times. 
 7. TREATMENT OF DEFERRED COMPENSATION ACCOUNT AND STOCK UNITS DURING DEFERRAL PERIOD 
 (a) Directed Investment Account. The balance of each Participant’s Directed Investment Account shall be adjusted, for earnings and losses
commencing with the date as of which any amount is credited to the Directed Investment Account. Such earnings or losses during the deferral period for amounts credited to a Participant’s Directed Investment Account shall be computed 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, which shall include a stable value fixed income fund (the
“Stable Value Fund”). Each participating Employee may select (in ten percent (10%) increments) which investment alternative(s) will be used for this purpose with respect to his or her deferred Compensation, and the alternative(s)
selected need not be the same as the Employee 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. 
 (b) Stock Unit Account. Amounts deemed invested in the Stock Unit Account may not be transferred to any other investment and must remain in the
Stock Unit Account until distributed to the Participant. On each dividend payment date, Dividend Equivalents shall be credited to each full and fractional Stock Unit to the extent such Stock Unit was in the Participant’s Stock Unit Account on
the dividend record date immediately preceding the applicable dividend payment date. As of the dividend payment date, the value of such Dividend Equivalents shall be credited to the Participant’s Directed Investment Account and initially shall
be deemed invested in the Stable Value Fund described in Section 7(a) above, subject to the Participant’s ability to subsequently change such investment in accordance with Section 7(a). 
 (c) Holding Account. The Holding Account shall be available only for the temporary holding of amounts pending conversion into Stock Units in
accordance with Section 6, and during such temporary holding period shall be deemed invested in the Stable Value Fund. Participants shall not be permitted to select the Holding Account as a deemed investment for their deferrals. 
 (d) Effect of Certain Transactions. In the event that there occurs a dividend or other distribution of shares of the Corporation’s common
stock (“Shares”), a dividend in the form of cash or other property that materially affects the fair market value of the Shares, a stock split, a reverse stock split, a split-up, a split-off, a spin-off, a combination or subdivision of
Shares or other securities of the Corporation, an exchange of Shares for other securities of the Corporation, or a similar transaction or event that materially affects the fair market value of the Shares, the Committee, in order to prevent
diminution or enlargement of the benefits or potential benefits intended to be made available under the Plan, shall make appropriate adjustments in the number of each Participant’s Stock Units determined as of the date of such occurrence.

  

 8 








 8. FORM AND TIME OF PAYMENT OF DEFERRED COMPENSATION ACCOUNT 
 Subject to Section 8(b), payment of a Participant’s Deferred Compensation Account shall commence on, or within the 30-day
period that begins on, the March 15th of the year following the year in
which Separation from Service occurs. A Participant may request an earlier distribution of an amount credited to his or her Deferred Compensation Account upon the occurrence of an unforeseeable emergency within the meaning of Section 409A and
the regulations thereunder as determined by the Committee, but only to the extent necessary to alleviate the emergency. Payment of a Participant’s Stock Units shall also be made at such time except that, within the six-month period beginning on
the last date on which Compensation has been converted into Stock Units on behalf of the Participant, to the extent that the Committee reasonably determines that earlier payment would result in a violation of Federal securities laws, payment of the
Participant’s Stock Units shall be made on, or within the 30-day period that begins on, the last day of the month in which such six-month period expires. Notwithstanding the previous sentence, Stock Unit payments shall be made following the
Participant’s death, Disability or the date of the Participant’s Separation from Service, without regard to whether such six-month period has expired. For the purpose of payment, Stock Units shall be converted to cash based on the Value of
the Corporation’s common stock on the last trading day of the month preceding the month during which the distribution is due to be made. 
 The amount of each installment payment due for a Deferred Compensation Account shall be determined by application of the Variable Fractions Method. Each annual installment for Years subsequent to the Year in which
payment commences shall be made on, or within the 30-day period that begins on, March 15th. 
 In the case of a Participant who has both Stock Units and other deemed investment accounts
available under Section 7, if a partial distribution of a deferred portion of Compensation is to be made and if the Participant’s Stock Units are immediately payable in accordance with the first paragraph of this Section, payment shall be
made partially from the Participant’s Stock Units and partially from such other deemed investment accounts, in proportion to the relative value of the Participant’s Stock Units and such other accounts. If the Participant’s Stock Units
are not immediately payable in accordance with the previous paragraph, the partial payment shall be made entirely from such other deemed investment accounts, in proportion to the relative value of such accounts. 
 Notwithstanding any other provision of the Plan to the contrary: 
 (a) No distribution shall be made from the Plan that would constitute an impermissible acceleration of payment as defined in Section 409A(a)(3) of the Code and regulations promulgated thereunder; and

 (b) A distribution 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 (6) months if the Participant’s distribution is triggered by his or her Separation from Service. Any payment that

  

 9 








 
otherwise would have been made except for the application of this subsection (b) during such six (6)-month period will be made in one (1) lump sum payment no later than the last day of
the second month following the month that is six (6) months from the date of the Participant’s Separation from Service. The Participant’s Deferred Compensation Account shall continue to be adjusted for earnings and losses and Dividend
Equivalents during the delay. The determination of which Participants are Key Employees will be made by the Corporation in its sole discretion in accordance with this subsection (b) and Sections 416(i) and 409A of the Code and the regulations
promulgated thereunder. 
 (i) “Identification Date” means each December 31. 
 (ii) “Key Employee” means an Employee who, on an Identification Date, is: 
 (A) An officer of the Corporation having annual compensation greater than the compensation limit in Section 416(i)(1)(A) (i) of the Code,
provided that no more than fifty (50) officers of the Corporation shall be determined to be Key Employees as of any Identification Date; 
 (B) A five percent (5%) owner of the Corporation; or 
 (C) A one percent (1%) owner of the Corporation having annual
compensation from the Corporation of more than $150,000. 
 If an Employee is identified as a Key Employee on an Identification Date, then
such Employee shall be considered a Key Employee for purposes of the Plan during the period beginning on the first April 1 following the Identification Date and ending on the next March 31. 
 (c) Notwithstanding the foregoing, a lump sum distribution shall be made in the Committee’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 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). 
 (d) If a Plan benefit is payable to a minor or a person declared incompetent or to a
person incapable of handling the disposition of property, the Committee may direct payment to the guardian, legal representative or person having the care and custody of such minor, incompetent or person. The Administrator may require proof of
incompetency, minority, incapability or guardianship as it may deem appropriate prior to distribution. Such distribution shall completely discharge the Committee, the trustees of any trusts, and the Corporation from all liability with respect to
such benefit. 
 9. EFFECT OF DEATH OF PARTICIPANT 
 Upon the death of a Participant, all amounts, if any, remaining in his or her Deferred Compensation Account shall be distributed to the Beneficiary designated by the Participant. Such distribution shall be made at
the time or times specified in the Participant’s deferral

  

 10 








 
election. 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. 
 10. CLAIMS AND REVIEW PROCEDURE 
 (a) Informal Resolution of Questions. Any participant who has questions or concerns about his or her deferred compensation under the Plan is
encouraged to communicate with the Vice President, Human Resources. If this discussion does not give the participant satisfactory results, a formal claim for benefits may be made within one (1) year of the event giving rise to the claim in
accordance with the procedures of this Section 10. 
 (b) Formal Benefits Claim - Review by Appeals Committee. A participant
may make a written request for review of any matter concerning his or her deferred Compensation under the Plan. The claim must be addressed to the Appeals Committee, Management Deferred Compensation Plan, Potlatch Corporation, 601 W. First Ave.,

 11 








 (ii) The Appeals Committee’s review shall take into account all comments, documents, records and

provisions of the Plan cited in the original denial of the claim. 
 (iii) The Appeals Committee shall issue a written decision within a
reasonable period of time but not later than sixty (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

 (v) The decision of the Appeals Committee on the appeal shall be final, conclusive and binding upon all persons and shall be given the
maximum possible deference allowed by law. 
 (e) Exhaustion of Remedies. No legal or equitable action for benefits under the Plan
shall be brought unless and until the claimant has submitted a written claim for benefits in accordance with Section 10(a) above, has been notified that the claim is denied in accordance with Section 10(c) above, has filed a written
request for a review of the claim in accordance with Section 10(d) above, and has been notified in writing that the Appeals Committee has affirmed the denial of the claim in accordance with Section 10(d) above; provided, however, that an
action for benefits may be brought after the Appeals Committee has failed to act on the claim within the time prescribed in Section 10(b) and Section 10(d), respectively. 
 11. PARTICIPANT’S RIGHTS UNSECURED 
 The interest under the Plan of any Employee and such
Employee’s right to receive a distribution from the Plan shall be an unsecured claim against the general assets of the Corporation. The Deferred Compensation Account and all deemed investment accounts available under Section 7 shall be
bookkeeping entries only and no Employee shall have an interest in or claim against any specific asset of the Corporation pursuant to the Plan. Notwithstanding the foregoing, the Corporation 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. 
  

 12 








 12. STATEMENT OF DEFERRED COMPENSATION ACCOUNT 
 The Committee shall provide a quarterly statement of each Participant’s Deferred Compensation Account. 
 13. NONASSIGNABILITY OF INTERESTS 
 The interest
and property rights of any Employee under the Plan shall not be subject to option nor be assignable either by voluntary or involuntary assignment or by operation of law, including (without limitation) bankruptcy, garnishment, attachment or other
creditor’s process, and any act in violation of this Section 13 shall be void. 
 14. ADMINISTRATION OF THE PLAN 
 The Plan shall be administered by the Committee. In addition to the powers and duties otherwise set forth in the Plan, the Committee shall have full
power and authority to administer and interpret the Plan, to establish procedures for administering the Plan and to take any and all necessary action in connection therewith, including retaining outside managers to assist with the administration of
the Plan. The Committee’s interpretation and construction of the Plan shall be conclusive and binding on all persons. In its discretion, the Committee may delegate to the Vice President, Human Resources the authority for the effective
administration of the Plan and for assigning responsibility to designated managers to carry out such duties. 
 Within thirty
(30) days after a Change of Control (as defined in Section 17), the Committee shall appoint an independent committee consisting of at least three (3) current (as of the effective date of the Change of Control) or former Corporation
officers and directors, which shall thereafter administer all claims for benefits under the Plan. Upon such appointment the Committee shall cease to have any responsibility for claims administration under the Plan. 
 15. AMENDMENT OR TERMINATION OF THE PLAN 
 (a)
The Board or the Committee may amend, suspend or terminate the Plan at any time. The foregoing notwithstanding, the Plan may not be amended (including any amendment to this Section 15) or terminated by the Board or the Committee if such

Board’s or the Committee’s discretion, be distributed within the period beginning twelve months after the date the Plan was terminated and ending twenty-four months after the date the Plan was terminated, or pursuant to Section 8, if
earlier. If the Plan is terminated and Deferred Compensation Accounts are distributed, the Board or the Committee shall terminate all account balance non-qualified deferred compensation plans with respect to all

Employees and shall not adopt a new account balance non-qualified deferred compensation plan for at least three (3) years after the date the Plan was terminated. A termination and
