AMENDED AND RESTATED SEVERANCE BENEFIT AGREEMENT

Exhibit 10.6

AMENDED AND RESTATED

SEVERANCE BENEFIT AGREEMENT

This Severance Benefit Agreement (the “Agreement”) is made as of March 1, 2013 between Leggett & Platt, Incorporated, No. 1 Leggett Road, Carthage, Missouri 64836 (the “Company”) and Karl G. Glassman (the “Executive”), residing at                                                       Missouri 64836.

RECITALS

The Executive functions as President and Chief Operating Officer of the Company on the date hereof and is one of the key employees of the Company.

The Company considers the maintenance of sound and vital management essential to protecting and enhancing the best interests of the Company and its shareholders. In this connection, the Company recognizes that in today’s business environment the possibility of a change in control of the Company may exist in the future. The Company further recognizes that such possibility, and the uncertainty which it may raise among key executives, could result in the departure or distraction of key executives to the detriment of the Company and its shareholders. Accordingly, the Board of Directors of the Company (the “Board”) has determined that appropriate steps should be taken (i) to further induce the Executive to remain with the Company and (ii) to reinforce and encourage the continued attention and dedication of the Executive to his assigned duties without distraction in the face of potentially disturbing circumstances arising from the possibility of a change in control of the Company. This Agreement supersedes the Severance Benefit Agreement between the Company and the Executive dated May 7, 2009.

NOW, THEREFORE, in consideration of the premises and for other good and valuable considerations, the receipt of which are hereby acknowledged, the Company and the Executive agree as follows:

1. Change in Control; Employment Agreement

1.1 Change in Control. The Company shall be required to provide certain benefits to the Executive to the extent required under the terms of this Agreement following each and every “Change in Control” of the Company.

A “Change in Control” of the Company shall be deemed to have occurred if:

1.2 Employment Agreement. Any benefits provided to the Executive under this Agreement will, unless specifically stated otherwise in this Agreement, be in addition to and not in lieu of any benefits that may be provided the Executive under his Employment Agreement with the Company dated March 1, 2013 (this agreement, as amended, restated or superseded, is called the “Employment Agreement”).

This Agreement shall continue for the term provided in Section 7.7 and shall not be affected by any termination of the Employment Agreement.

2. Termination of Employment Following a Change in Control

2.1 General. During the 30 month period immediately following each and every Change in Control (the “Protected Period”), the Executive and the Company shall comply with all provisions of this Section 2 regarding termination of the Executive’s employment. This Agreement shall have no application to any termination of the Executive’s employment outside the Protected Period.

2.2 Termination for Total Disability. The Company may terminate the Executive’s employment during the Protected Period due to the Executive’s Total Disability. “Total Disability” means the Executive’s inability to perform substantially all of his material duties with the Company for a continuous period of six or more months due to illness or injury. During any period prior to his termination of employment that the Executive is unable to substantially perform his duties with the Company as a result of illness or injury, the Company shall continue to pay the Executive his full base salary at the rate then in effect and any bonuses earned by the Executive under Company bonus plans until such time as the Executive’s employment is

2

terminated by the Company for Total Disability. In no event, however, shall such period of continued pay and bonus exceed 29 consecutive months. Following termination of employment under this Section 2.2, the Executive’s benefits shall be determined in accordance with the Company’s long term disability program as in effect on the date hereof, or any successor program then in effect.

2.3 Termination by Company for “Cause”. If the Employment Agreement is not in force, the Company may terminate the Executive’s employment during the Protected Period for Cause as defined in this Agreement. If the Employment Agreement is in force, the Company may terminate the Executive’s employment for “Cause” (as defined in the Employment Agreement) only in accordance with the terms of the Employment Agreement.

Termination for “Cause” under this Agreement, as distinguished from the Employment Agreement, shall be limited to the following:

3

No act or failure to act on the Executive’s part shall be considered “willful” unless done, or omitted to be done, by the Executive without reasonable belief that his action or omission was in the best interest of the Company. Moreover, the Executive’s employment shall not be terminated for Cause unless and until there shall have been delivered to the Executive a notice of termination duly adopted by the affirmative vote of at least a majority of the directors of the Board at a meeting of the Board (after reasonable notice to the Executive and an opportunity for the Executive, together with his counsel, to be heard before the Board), finding that in the good faith opinion of the Board the Executive was in violation of Section 2.3(a), (b), (c), (d),(e) or (f) and specifying the particulars thereof in detail.

A termination shall not be deemed for Cause if, for example, the termination results from the Company’s determination that the Executive’s position is redundant or unnecessary or that the Executive’s performance is unsatisfactory or if the termination stems from the Executive’s refusal to agree to or accept any Company Action described in Section 2.4.

2.4 Termination by Executive for Good Reason. The Executive may, whether or not his Employment Agreement remains in force, terminate his employment during the Protected Period for “Good Reason” by giving notice of termination to the Company following (i) any action or omission by the Company described in this Section 2.4 or (ii) receipt of notice from the Company of the Company’s intention to take any such action or engage in any such omission. A termination of employment under this Section 2.4 shall be deemed a valid and proper termination of the Employment Agreement if then in force and, to this extent, the parties agree that the Employment Agreement is hereby amended.

The actions or omissions which may lead to a termination of employment for Good Reason (herein collectively and severally “Company Actions”) are as follows:

4

obligations immediately prior to the Change in Control or, if the Executive consents in writing to any relocation, the failure by the Company to pay (or reimburse the Executive for) all reasonable expenses incurred by him relating to a change of his principal residence in connection with such relocation; or

2.5 Notice of Termination and Opportunity to Cure. Any purported termination by the Company of the Executive’s employment under Section 2.2 (Total Disability) or 2.3 (for Cause) or by the Executive under Section 2.4 (for Good Reason) shall be communicated by notice of termination to the other party. A notice of termination shall mean a notice which includes the specific termination Section in this Agreement relied upon and shall set forth, in reasonable detail, the facts and circumstances claimed to provide a basis for termination of employment under the Section so indicated. Notice of termination for Good Reason under Section 2.4 shall be made by the Executive no later than 90 days from the date such Good Reason first arises. If, within 30 days of receipt of such notice, the Company takes such appropriate actions as are necessary to correct, reverse or cure these facts and circumstances that the Executive identifies as causing Good Reason, then no Good Reason shall have occurred.

2.6 Date of Termination. The date the Executive’s employment is terminated under Section 2 of this Agreement is called the “Date of Termination”. In cases of Total Disability, the Date of Termination shall be 30 days after notice of termination is given (provided that the Executive shall not have returned to the performance of his duties on a full-time basis during such prior 30 day period). If the Executive’s employment is terminated for Cause, the Date of Termination shall be the date specified in the notice of termination. If the Executive’s employment is terminated for Good Reason, the Date of Termination shall be the date set out in the notice of termination, which shall not be later than 60 days following the date of the notice of termination, provided that the Company fails to correct, reverse or cure the facts giving rise to such Good Reason, as provided in Section 2.5.

Any dispute by a party hereto regarding a notice of termination delivered to such party must be conveyed to the other party within 30 days after the notice of termination is given. If the particulars of the dispute are not conveyed within the 30 day period, then the disputing party’s claims regarding the termination shall be forever deemed waived.

5

2.7 Prior Notice Required of Company Actions. During the Protected Period, the Company shall not terminate the Executive’s employment (except for Total Disability or for Cause or pursuant to the Employment Agreement) or take any Company Action as defined in Section 2.4 without first giving the Executive at least three months’ prior notice of termination or the planned Company Action, as the case may be.

3. Benefits upon Termination of Employment

3.1 General. If, during the Protected Period following each Change in Control, the Executive’s employment is terminated either (i) by the Company (other than for Total Disability or Cause under this Agreement and other than for “Total Disability” or “Cause” under the terms of the Employment Agreement) or (ii) by the Executive for Good Reason, then the Executive shall be entitled to the benefits provided in this Section 3 (collectively and severally “Termination Benefits”) in lieu of receiving the compensation and benefits provided for in Section 8.2 of the Employment Agreement.

3.2 Base Salary Through Date of Termination. The Company shall pay the Executive his full base salary through the Date of Termination under the Company’s regular payroll procedures and at the rate in effect at the time notice of termination is given. The Company shall give the Executive credit for any vacation earned but not taken and pay such amount at the time that any earned but not yet paid bonus is paid under Section 3.3.

3.3 Pro-Rata Bonus for Year of Termination. The Company shall pay the Executive a pro rata bonus for the year in which his employment terminates. The pro rata bonus shall be equal to “A” divided by “B” with the quotient multiplied by “C” where:

Such amount shall be paid when bonuses are required to be paid under the Company’s Key Officer Incentive Plan (or successor plan) but not before 6 months after the Executive’s termination of employment if and to the extent required to avoid a tax under Section 409A of the Internal Revenue Code of 1986 (the “Code”).

3.4 Monthly Severance Payments. The Company shall pay the Executive:

6

The severance payments in subsection (a) and subsection (b) shall each be made in 30 equal, consecutive monthly installments.

3.5 Welfare Plans and Fringe Benefits.

(a) For purposes of this Section 3.5, welfare plans and fringe benefit programs include health, disability, life, salary continuance prior to disability, automobile usage, and any other fringe benefit or welfare plan arrangement in which the Executive was entitled to participate immediately prior to the Date of Termination.

(b) The Company shall maintain in full force, for the continued benefit of the Executive for 30 months after the Date of Termination, at the same cost to the Executive as is charged to similarly situated active employees, all welfare plans and fringe benefit programs (including health plan, disability insurance, and life insurance, including any applicable spouse and eligible dependent coverage) that the Company is able to provide under the terms of its plans, programs, and applicable policies and that may be provided to the Executive as a former employee on a tax-free basis under the Code and without the Company incurring a tax under Code Section 4980D; provided, however, that the Company may require the Executive to elect coverage pursuant to COBRA as condition to continuing medical plan coverage, if and to the extent the Executive is eligible for COBRA.

(c) To the extent that any welfare plan or fringe benefit program cannot be maintained under Section 3.5(b) above on a tax-free basis to the Executive under the applicable provisions of the Code, such benefits that the Company is able to provide under the terms of its plans, programs, and applicable policies and without the Company incurring a tax under Code Section 4980D shall be continued, at the same cost to the Executive as is charged to similarly situated active employees, for the period, if any, that is recognized under Code Section 409A as not resulting in a deferral of compensation, but in no event beyond 30 months.

(d) To the extent any welfare plan or fringe benefit program cannot be provided for 30 months from the Date of Termination under Sections 3.5(b) and (c) above, the Executive shall be entitled to monthly cash payments that equal the Company’s cost of coverage in the case of welfare plans and in the case of fringe benefit programs that require payment of a premium, and in other cases the value of benefits that would have been provided during such period. At the close of the 30 month period, any assignable insurance policy owned by the Company and relating solely to the Executive shall be assigned to the Executive.

3.6 Retirement Plans.

(a) The Company shall pay the Executive an “Additional Retirement Benefit” equal to the additional benefit the Executive would have been entitled to under the Company’s

7

Retirement Plans in effect immediately prior to a Change in Control had the Executive accumulated 30 additional months of continuous service (following the Date of Termination) under such Retirement Plans both for purposes of determining eligibility for benefits and for purposes of calculating the Additional Retirement Benefit. If any Retirement Plan requires contributions by participants, the Additional Retirement Benefit shall be reduced to reflect the absence of contributions by the Executive and any matching contribution that would be contingent upon the Executive’s contributions shall be calculated as if the Executive made the maximum contribution allowable under the terms of such Retirement Plan. Where the Executive’s contribution for a given Retirement Plan is calculated by reference to salary and/or bonus, the Additional Retirement Benefit shall be calculated by reference to the Executive’s annual salary in effect on the date of the Executive’s notice of termination and the bonus payout percentage achieved for the year of service preceding the Executive’s notice of termination, without adjustment for any future year increases that may have occurred absent the termination.

(b) For purposes of this Section 3.6, “Retirement Plans” are (i) any savings or retirement plan sponsored by the Company that is intended to be tax-qualified under Internal Revenue Code section 401(a), and any arrangements that make up benefits that are not provided under such tax-qualified plans because of compensation or benefit limits under the terms of such plans or the Internal Revenue Code, (ii) the Executive Stock Unit Program, and (iii) any deferred compensation program in which the Executive participates that is adopted after the effective date of this agreement that is intended to provide for retirement savings. For any Retirement Plan that is a defined benefit pension plan, the Additional Retirement Benefit shall be determined using the same interest rate and mortality factor that apply for determining actuarial equivalence in the applicable plans.

3.7 Termination Which Does Not Require Payment of Termination Benefits. No Termination Benefits shall be provided by the Company to the Executive under this Section 3 if the Executive’s employment is terminated:

3.8 Modified Cutback. If the Executive is entitled to Termination Benefits under this Agreement and other payments and/or benefits in connection with a change of ownership or effective control of the Company covered by §280G of the Code, as amended (collectively the “Company Payments”), and if such Company Payments would otherwise equal or exceed 300% of the Executive’s base amount as defined in §280G(b)(3) of the Code (the “Threshold Amount”), then the amount of the Company Payments will be reduced to an amount that is less than such Threshold Amount, but only if and to the extent such reduction will also result in, after taking into account all taxes, including any income taxes (together with any interest or penalties thereon, the “Additional Income Tax”) and any excise tax pursuant to Code §4999, a greater after-tax benefit to the Executive than the after-tax benefit to the Executive of the Company

8

Payments computed without regard to any such reduction. If Company Payments must be reduced, the order of reduction shall be in accordance with Code Section 409A and unless otherwise required to satisfy Code Section 409A, (a) the amount of severance payable to the Executive under Section 3.4 of this Agreement shall be subject to reduction first, followed by payments under Section 3.5 of this Agreement, followed by cash payments under Section 3.6 of this Agreement, followed by any other cash payments that are not attributable to accelerated vesting or payment of Company stock, stock units or stock options, followed by payments under this Agreement that are not subject to Section 409A, followed by payments that are attributable to accelerated vesting or payment of Company stock, stock units or stock options, and (b) subject to the order of reductions specified in Subsection (a), the payments that would otherwise be made latest in time shall be reduced first and payments that would be otherwise be made at the same time shall be reduced pro rata.

To the extent requested by the Executive, the Company shall cooperate with the Executive in valuing services provided by the Executive (including, without limitation, the Executive refraining from performing services pursuant to a covenant not compete) before, on or after a change in ownership or control of the Company (within the meaning of §280G of the Code), such that payments in respect of such services may be considered reasonable compensation and/or exempt from the definition of “parachute payment” within §280G of the Code.

4. No Obligation to Mitigate

The Termination Benefits provided under Section 3 shall not be treated as damages, but rather shall be treated as severance compensation to which the Executive is entitled. The Executive shall not be required to mitigate the amount of any Termination Benefit provided under Section 3 by seeking other employment or otherwise; provided, however, any health welfare and fringe benefits that the Executive may receive from full time employment by a third person shall be applied against and reduce any such benefits thereafter to be made available to the Executive under Section 3.5.

5. Timing of Payments

The taxable payments and taxable benefits in Sections 3.4 and 3.5 shall commence 6 months after the Executive’s termination of employment, at which date he shall receive in a lump sum of installments and benefits which accrued from the date of his termination of employment through the date of such lump sum payment. Additional Retirement Benefits under Section 3.6 shall be paid in a lump sum 6 months after the Executive’s termination of employment; provided, however, that in the case of a Retirement Plan that is not a tax-qualified plan, payment shall be made at such later date or event that is specified in such plan if the payment time or event is one described in Code Section 409A(a)(2)(A). Any coverage and benefits pursuant to Section 3.5 that are not taxable to the Executive shall commence within 60 days following the date of termination and the coverage or benefits shall be retroactive to the date of termination of employment.

6. Successor; Binding Agreement

The Company will require any successor (whether direct or indirect, by purchase, merger, consolidation or otherwise) to all or substantially all of the business and/or assets of the Company to expressly assume and agree to perform this Agreement in the same manner and to the same extent that the Company would be required to perform it if no such succession had taken place. The assumption shall be by agreement in form and substance satisfactory to the Executive. Failure of the Company to obtain such agreement prior to the effectiveness of any such succession shall entitle the Executive to terminate his employment for Good Reason as provided in Section 2.4(h). As used in the Agreement “Company” means the Company as previously defined and any successor to its business and/or assets which executes and delivers the agreement provided for in this Section 6 or which otherwise becomes bound by all the terms and provisions of this Agreement by operation of law.

This Agreement shall inure to the benefit of and be enforceable by the Executive’s personal or legal representatives, executors, administrators, successors, heirs, distributes, devisees and legatees, but the Executive may not assign this Agreement. If the Executive should die while any amount would still be payable to him hereunder if he had continued to live, all such amounts, unless otherwise provided herein, shall be paid in accordance with the terms of this Agreement to his devisee, legatee or other designee or, if there be no such designee, to his estate.

7. Miscellaneous

7.1 Notice. All notices, elections, waivers and all other communications provided for in this Agreement shall be in writing and shall be deemed to have been duly given when delivered or mailed by United States certified mail, return receipt requested, postage prepaid, addressed to the respective addresses set forth on the first page of this Agreement, or to such other address as either party may have furnished to the other in writing in accordance herewith, except that notices of change of address shall be effective only upon receipt.

7.2 No Waiver. No provisions of this Agreement may be modified, waived or discharged unless such waiver, modification or discharge is agreed to in writing, signed by the Executive and an officer of the Company. No waiver by either party at any time of any breach by the other party of, or compliance with, any condition or provision of this Agreement to be performed by such other party shall be deemed a waiver of similar or dissimilar provisions or conditions at the same or at any prior or subsequent time. No agreements or representations, oral or otherwise, express or implied, with respect to the subject matter hereof have been made by either party which are not set forth expressly in this Agreement.

7.3 Enforceability. The invalidity or unenforceability of any provisions of this Agreement shall not affect the validity or enforceability of any other provision of this Agreement, which shall remain in full force and effect.

7.4 Governing Law. This Agreement shall be governed by and construed in accordance with the internal laws of the State of Missouri.

10

7.5 Disputes. Any dispute or controversy arising under or in connection with this Agreement shall be settled by arbitration in accordance with the Commercial Arbitration Rules procedures of the American Arbitration Association. If, at any time after 90 days from the date of the Executive’s termination of employment, the Executive and the Company have not resolved any dispute or controversy arising under or in connection with this Agreement, either the Executive or the Company may notify the other of an intent to seek arbitration. Arbitration shall occur before a single arbitrator in the State of Missouri; provided, however, that if the parties cannot agree on the selection of such arbitrator within 30 days after the matter is referred to arbitration, each party shall select one arbitrator and those arbitrators shall jointly designate a third arbitrator to comprise a panel of three arbitrators. The decision of the arbitrator shall be rendered in writing, shall be final, and may be entered as a judgment in any court in the State of Missouri. Company and the Executive each irrevocably consent to the jurisdiction of the federal and state courts located in the State of Missouri for this purpose. The Company shall pay, within 30 days of receipt of the arbitrator’s decision, all costs and expenses in connection with any arbitration under this Section 7.5, including without limitation all reasonable legal fees incurred by Executive in connection with such arbitration; provided, however, the Company shall not be obligated to pay unless the Executive prevails on the majority of the dollar amount at issue in the dispute.

7.6 Sections; Captions. All references in this Agreement to Sections refer to the applicable Sections of this Agreement. References in this Agreement to a given Section (e.g., Section 3) shall, unless the context requires otherwise, refer to all parts of such Section.

The captions have been placed in this Agreement for ease of reference only. They shall not be used in the interpretation of this Agreement.

7.7 Term of Agreement. This Agreement shall continue in force so long as the Executive remains employed by the Company or any successor and shall apply to any Change in Control that occurs while the Executive remains so employed, except as so modified by the parties from time to time, including modifications to take into account changes in law.

7.8 Limited Right of Offset. Effective upon a Change in Control, the Company waives, and will not assert, any right to set off the amount of any claims, liabilities, damages or losses the Company may have against the Executive under this Agreement or otherwise if (i) the Executive’s employment is terminated by the Company without Cause, or (ii) the Executive terminates his employment for “Good Reason”.

7.9. Release. Notwithstanding any other provision of this Agreement, the Executive shall receive payments and benefits under this Agreement only if the Executive timely executes, returns to the Company, and does not revoke a release and covenant not to sue agreement, in a form reasonably acceptable to the Executive and the Company’s legal counsel. The Company shall provide such agreement to the Executive in sufficient time so that if the Executive executes and returns the agreement to the Company within the time period permitted by the Company, the revocation period provided in the agreement will expire before the payments and benefits under this Agreement are required to commence pursuant to Section 5.

11

7.10 Successive Changes in Control. A separate Change in Control shall be deemed to have occurred with each occurrence of any event described at subsections (a) through (e) of Section 1.1. This Agreement pertains to each and every Change in Control, including successive Changes in Control involving the same controlling person(s).

7.11 Interpretation of Agreement and Application of Code Section 409A. This Agreement is intended to conform to the requirements of Code Section 409A and shall be interpreted accordingly. For such purposes, any stream of payments due under this Agreement shall be treated as a series of separate payments. The Executive shall be deemed to have terminated employment for purposes of this Agreement only if he has incurred a termination of employment that constitutes a “separation for service” within the meaning of Code Section 409A.

7.12 Withholding. The Company may withhold all federal, state, and local income and employment taxes as required under applicable laws and regulations.

IN WITNESS WHEREOF, this Agreement has been signed as of the day and year first above written.
