CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

This prospectus, as well as the documents incorporated by reference herein, whether written or oral, may contain “forward-looking” statements within the meaning of the Private Securities Litigation Reform Act of 1995, including, but not limited to, projections of revenue, income, earnings, capital expenditures, dividends, capital structure, cash flows or other financial items; possible plans, goals, objectives, prospects, strategies or trends concerning future operations; statements concerning future economic performance; possible goodwill or other asset impairment; and the underlying assumptions relating to forward-looking statements. These statements are identified either by the context in which they appear or by use of the words such as “anticipate,” “believe,” “estimate,” “expect,” “intend,” “may,” “plan,” “project,” “should” or the like. All such forward-looking statements, whether written or oral, and whether made by us or on our behalf, are expressly qualified by the cautionary statements described in this provision.

Any forward-looking statement reflects only the beliefs of Leggett & Platt or its management at the time the statement is made. Because all forward-looking statements deal with the future, they are subject to risks, uncertainties and developments which might cause actual events or results to differ materially from those envisioned or reflected in any forward-looking statement. Moreover, we do not have, and do not undertake any duty to update or revise any forward-looking statement to reflect events or circumstances after the date on which the statement was made. For all of these reasons, forward-looking statements should not be relied upon as a prediction of actual future events, objectives, strategies, trends or results.

Readers should review Item 1A Risk Factors in our most recent Form 10-K, as updated by our quarterly reports on Form 10-Q, as well as “Risk Factors” in this prospectus and in any applicable prospectus supplement, for a description of important factors, many of which are beyond our control, that could cause actual events or results to differ materially from forward-looking statements. It is not possible to anticipate and list all risks, uncertainties and developments which may affect our future operations or performance, or which otherwise may cause actual events or results to differ materially from forward-looking statements. However, the known material risks and uncertainties include the following:

ABOUT THIS PROSPECTUS

This prospectus is part of a registration statement that we filed with the Securities and Exchange Commission, or SEC, using a “shelf” registration process. Under this shelf process, we or any selling security holder may, from time to time, sell the securities or combinations of the securities described in this prospectus in one or more offerings. For further information about our business and the securities, you should refer to the registration statement and its exhibits. The exhibits to our registration statement contain the full text of certain contracts and other important documents we have summarized in this prospectus. Since these summaries may not contain all the information that you may find important in deciding whether to purchase the securities we offer, you should review the full text of these documents. The registration statement and the exhibits can be obtained from the SEC as indicated under the heading “Where You Can Find More Information.”

This prospectus provides you with a general description of the securities that we or selling security holders may offer. Each time we or such security holders offer securities, we will provide a prospectus supplement and/or other offering material that will contain specific information about the terms of that offering. When we refer to a “prospectus supplement,” we are also referring to any free writing prospectus or other offering material authorized by us. If there is any inconsistency between the information in this prospectus and the applicable prospectus supplement, you should rely on the information in the prospectus supplement. The prospectus supplement may also add, update or change information contained in this prospectus. You should read this prospectus and any prospectus supplement together with additional information described under the heading “Where You Can Find More Information.”

You should rely only on the information incorporated by reference or provided in this prospectus or in any prospectus supplement. We have not authorized anyone to provide you with different information. We are not making an offer of these securities in any state where the offer is not permitted. You should not assume that the information in this prospectus, any prospectus supplement or any document which we incorporate by reference is accurate as of any date other than its respective date. Our business, financial condition, results of operations and prospects may have changed since those dates.

Unless the context otherwise requires, in this prospectus “Leggett & Platt,” “Company,” “we,” “us,” “our” and “ours” refer to Leggett & Platt, Incorporated and its subsidiaries.

RISK FACTORS

Investing in our securities involves risks. You should carefully consider the risks described under “Risk Factors” in Item 1A of our most recent Annual Report on Form 10-K, as updated by our quarterly reports on Form 10-Q, and in the other documents incorporated by reference into this prospectus (which risk factors are incorporated by reference herein), as well as the other information contained or incorporated by reference in this prospectus or in any prospectus supplement hereto before making a decision to invest in our securities. Each of these risk factors could have a material adverse effect on our business, results of operations, financial position or cash flows, which may result in the loss of all or part of your investment. See “Where You Can Find More Information.”

SELLING SECURITY HOLDERS

We may register securities covered by this prospectus for re-offers and resales by any selling security holders to be named in a prospectus supplement. Because we are a well-known seasoned issuer, as defined in Rule 405 of the Securities Act, we may add secondary sales of securities by any selling security holders by filing a prospectus supplement with the SEC. We may register these securities to permit selling security holders to resell their securities when they deem appropriate. A selling security holder may resell all, a portion or none of such security holder’s securities at any time and from time to time. Selling security holders may also sell, transfer or otherwise dispose of some or all of their securities in transactions exempt from the registration requirements of the Securities Act. We do not know when or in what amounts any selling security holders may offer securities for sale under this prospectus and any prospectus supplement. We may pay some or all expenses incurred with respect to the registration of the securities owned by the selling security holders. We will provide a prospectus

2

supplement naming any selling security holders, the amount of securities to be registered and sold and any other terms of securities being sold by each selling security holder.

USE OF PROCEEDS

Unless we specify another use in the applicable prospectus supplement, we will use the net proceeds from the sale of any securities offered by us for general corporate purposes. Such general corporate purposes may include working capital additions, investments in or extensions of credit to our subsidiaries, capital expenditures, stock repurchases, debt repayment or financing for acquisitions. Pending such use, the proceeds may be invested temporarily in short-term, interest-bearing, investment-grade securities or similar assets. Except as may otherwise be specified in the applicable prospectus supplement, we will not receive any proceeds from any sales of securities by any selling security holder.

RATIO OF EARNINGS TO FIXED CHARGES

The following table sets forth the ratio of earnings to fixed charges for the periods indicated:

Earnings consist principally of income from continuing operations before income taxes, plus fixed charges (interest expense, capitalized interest, and implied interest included in operating leases) less capitalized interest and equity-method investment (earnings) or loss for the periods presented. We have not paid a preference security dividend for any of the periods presented, and accordingly have not separately shown the ratio of combined fixed charges and preference dividends to earnings for these periods.

DESCRIPTION OF DEBT SECURITIES

The following description of the terms of the debt securities sets forth general terms that may apply to the debt securities. The particular terms of any debt securities will be described in the prospectus supplement relating to those debt securities.

The debt securities will be either our senior debt securities or our subordinated debt securities. For purposes of this description of debt securities, the terms “we,” “our,” “ours” and “us” refer only to Leggett & Platt, Incorporated and not to any of its subsidiaries.

The Indentures

The senior debt securities will be issued in one or more series under our Senior Indenture, dated May 6, 2005, between us and U.S. Bank National Association, as successor trustee. The subordinated debt securities will be issued in one or more series under a subordinated indenture, to be entered into by us and a financial institution as trustee, if and when we issue subordinated debt securities. The description of the indentures set forth below assumes that we enter into a subordinated indenture. The statements herein relating to the debt securities and the indentures are summaries and are subject to the detailed provisions of the applicable indenture, and may not contain all of the information you may find useful. Each of the indentures will be subject to and governed by the Trust Indenture Act of 1939 (the “Trust Indenture Act”). We urge you to read the indentures because they, and not the summaries, define many of your rights as a holder of our debt securities. If you would like to read the indentures, they are on file with the SEC, as described under “Where You Can Find More Information.” Whenever we refer to particular sections or defined terms in an indenture, those sections and definitions are incorporated by reference.

3

General

The indentures do not limit the aggregate amount of debt securities which we may issue nor do they limit other debt we may issue. We may issue debt securities under the indentures up to the aggregate principal amount authorized by our board of directors from time to time. Except as may be described in a prospectus supplement, the indentures will not limit the amount of other secured or unsecured debt that we may incur or issue.

The debt securities will be our unsecured general obligations. The senior debt securities will rank equally with all our other unsecured and unsubordinated obligations. Unless otherwise specified in the applicable prospectus supplement, the subordinated debt securities will be subordinated and junior in right of payment to all our present and future senior indebtedness to the extent and in the manner set forth in the subordinated indenture. See “Subordination of the Subordinated Debt Securities” below. The indentures provide that the debt securities may be issued from time to time in one or more series. Unless otherwise provided, all debt securities of any one series may be reopened for issuance of additional debt securities of such series. (Section 3.1 of each indenture). We may authorize the issuance and provide for the terms of a series of debt securities pursuant to a supplemental indenture.

The applicable prospectus supplement relating to the particular series of debt securities will describe specific terms of the debt securities offered thereby, including, where applicable:

4

Unless otherwise specified in the applicable prospectus supplement, the debt securities will not be listed on any securities exchange or included in any market.

None of our shareholders, officers or directors, past, present or future, will have any personal liability with respect to our obligations under the indenture or the debt securities on account of that status. (Section 1.14 of each indenture).

Debt securities may also be issued pursuant to the indenture in transactions exempt from the registration requirements of the Securities Act. Those debt securities will not be considered in determining the amount of securities issued under this registration statement.

Form and Denominations

Unless we specify otherwise in the applicable prospectus supplement, debt securities will be issued only in fully registered form, without coupons, and will be denominated in U.S. dollars issued only in denominations of U.S. $1,000 and any integral multiple thereof. (Section 3.2 of each indenture).

Original Issue Discount Securities

Debt securities may be sold at a substantial discount below their stated principal amount and may bear no interest or interest at a rate which at the time of issuance is below market rates. Important federal income tax consequences and special considerations applicable to any such debt securities will be described in the applicable prospectus supplement.

Indexed Securities

If the amount of payments of principal of, and premium, if any, or any interest on, debt securities of any series is determined with reference to any type of index or formula or changes in prices of particular securities or commodities, the federal income tax consequences, specific terms and other information with respect to such debt securities and such index or formula and securities or commodities will be described in the applicable prospectus supplement.

Foreign Currencies

If the principal of, and premium, if any, or any interest on, debt securities of any series are payable in a foreign or composite currency, the restrictions, elections, federal income tax consequences, specific terms and other information with respect to such debt securities and such currency will be described in the applicable prospectus supplement.

5

Optional Redemption, Prepayment or Conversion in Certain Events

The prospectus supplement relating to a particular series of debt securities which provides for the optional redemption, prepayment or conversion of such debt securities on the occurrence of certain events, such as a change of control of us, will provide if applicable:

Payment

Unless we specify otherwise in the applicable prospectus supplement:

If we do not pay interest when due, that interest will no longer be payable to the registered holder of the debt securities on the record date for such interest. We will pay any defaulted interest, at our election:

Transfer and Exchange

Unless we specify otherwise in the applicable prospectus supplement, debt securities in registered form will be transferable or exchangeable at the agency maintained for such purpose we designate from time to time. Debt

6

securities may be transferred or exchanged generally without service charge, other than any tax or other governmental charge imposed in connection with such transfer or exchange. (Section 3.5 of each indenture). We have appointed the trustee under the senior indenture as security registrar with respect to securities issued under that indenture.

Consolidation, Merger, Conveyance, Sale of Assets and Other Transfers

We may not consolidate with or merge with or into, whether or not we are the surviving corporation, or sell, assign, convey, transfer or lease our properties and assets substantially as an entirety to any person, unless:

Upon the consolidation, merger or sale, the successor corporation formed by the consolidation, or into which we are merged or to which the sale is made, will succeed to, and be substituted for us under each indenture. (Section 10.2 of each indenture).

Unless we specify otherwise in the applicable prospectus supplement, the indenture and the terms of the debt securities will not contain any covenants designed to afford holders of any debt securities protection in a highly leveraged or other transaction involving us, whether or not resulting in a change of control, which may adversely affect holders of the debt securities.

Although there is a limited body of case law interpreting the phrase “substantially as an entirety,” there is no precise established definition of the phrase under applicable law. Accordingly, in certain circumstances there may be a degree of uncertainty as to whether a particular transaction would involve a disposition of our properties and assets “substantially as an entirety.” As a result, it may be unclear as to whether the merger, consolidation or sale, transfer or lease of assets covenant would apply to a particular transaction as described above absent a decision by a court of competent jurisdiction.

Limitations on Liens

Unless we specify otherwise in the applicable prospectus supplement or as permitted below, neither we nor any subsidiary will create or have outstanding any mortgage, lien, pledge or other encumbrance upon any property, without providing that the debt securities will be secured equally and ratably or prior to the debt.

A subsidiary generally is any corporation or other entity of which we or one of our subsidiaries owns more than 50% of the total voting power of shares of capital stock.

The limitation on liens does not apply to:

7

The limitation also does not apply to any liens not excluded by the above examples if at the time and after giving effect to any debt secured by a lien such liens do not exceed 15% of our consolidated assets. (Section 12.5 of each indenture).

“Consolidated assets” is defined to mean the gross book value of the assets of the Company and our subsidiaries, determined on a consolidated basis in accordance with generally accepted accounting principles.

Limitations on Sale and Leaseback

Unless we specify otherwise in the applicable prospectus supplement or as permitted below, neither we nor any subsidiary of ours will enter into any sale and leaseback transaction. A sale and leaseback transaction occurs when we or a subsidiary of ours sells or arranges to sell or transfer a principal property back to a lender or other third party and we or our subsidiary will in turn lease the principal property back from the lender or other third party, except for temporary leases for a term, including renewals at the option of the lessee, if not more than three years and except for leases between us and one of our subsidiaries or between our subsidiaries. A “principal property” is any of our owned or leased manufacturing plants located in the United States of America, not including any plant(s) our board of directors determines are not of material importance to the business of our company and its subsidiaries taken as a whole.

The restrictions on sale and leaseback transactions do not apply where either: (a) we or a subsidiary would be entitled to create debt secured by a lien on the property to be leased in an amount at least equal to “attributable debt” (as referred to below), without equally and ratably securing the debt securities, or (b) within a period twelve months before and twelve months after the consummation of the sale and leaseback transaction, we or one of our subsidiaries generally expends on the property, an amount equal to:

Attributable debt is the present value discounted at the interest rate implicit in the terms of the lease of the lessee’s obligation for the remaining net rent payments due under the remaining term of the lease, including any effective renewal term or period which may, at the option of the lessor, be extended.

8

The limitation on sale and leaseback transactions also does not apply if at the time of the sale and leaseback we apply, within 90 days of the effective date of any transaction, a cash amount equal to the attributable debt to retire debt for money we or our subsidiaries borrowed, not subordinate to the debt securities, which matures at, or is extendible or renewable to, a date more than 12 months after the creation of the debt at the obligor’s sole option without the consent of the obligee. (Section 12.6 of each indenture).

Waiver of Certain Covenants

The indentures provide that we will not be required to comply with certain restrictive covenants, including those described above under “Limitations on Liens” and “Limitations on Sale and Leaseback,” if the holders of at least a majority in principal amount of each series of outstanding debt securities affected waive compliance with the restrictive covenants. (Section 12.7 of each indenture).

Modification or Amendment of the Indentures

Supplemental Indentures with Consent of Holders. If we receive the consent of the holders of at least a majority in principal amount of the outstanding debt securities of each series affected, we may enter into supplemental indentures with the trustee for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of each indenture or of modifying in any manner the rights of the holders under the indenture of such debt securities and coupons, if any.

However, unless we receive the consent of all of the affected holders, we may not enter into supplemental indentures that would, with respect to the debt securities of such holders:

9

Supplemental Indentures Without Consent of Holders. Without the consent of any holders, we and the trustee may enter into one or more supplemental indentures for certain purposes, including:

It is not necessary for holders of the debt securities to approve the particular form of any proposed supplemental indenture, but it is sufficient if the holders approve the substance thereof. (Section 11.2 of each indenture).

A supplemental indenture which changes or eliminates any covenant or other provision of the indenture to which it relates with respect to one or more particular series of debt securities and coupons, if any, or which modifies the rights of the holders of debt securities or any coupons of such series with respect to such covenant or other provision, will be deemed not to affect the rights under such indenture of the holders of debt securities and coupons, if any, of any other series. (Section 11.2 of each indenture).

Subordination of the Subordinated Debt Securities

Any subordinated debt securities issued by us will be subordinated and junior in right of payment to all present and future senior indebtedness to the extent provided in the subordinated indenture. (Section 17.1 of the subordinated indenture). Unless we specify in the applicable prospectus supplement, the term “senior indebtedness” means the principal, any premium, and interest on:

10

The senior indebtedness will continue to be senior indebtedness and entitled to the benefits of the subordination provisions irrespective of any amendment, modification or waiver of any term of the senior indebtedness or extension or renewal of the senior indebtedness.

Unless we specify otherwise in the applicable prospectus supplement, senior indebtedness will not include:

Unless we specify otherwise in a prospectus supplement, no direct or indirect payment, in cash, property or securities, by setoff or otherwise, shall be made or agreed to be made on account of the subordinated debt securities or interest thereon or in respect of any repayment, redemption, retirement, purchase or other acquisition of subordinated debt securities, if:

Unless we specify otherwise in the applicable prospectus supplement, all present and future senior indebtedness, including, without limitation, interest accruing after the commencement of any proceeding described below, assignment or marshaling of assets, shall first be paid in full before we make any payment or distribution, in cash, securities or other property, on account of subordinated debt securities in the event of:

Unless we specify otherwise in the applicable prospectus supplement, in any such event, payments or distributions which would be made on subordinated debt securities will generally be paid to the holders of senior indebtedness in accordance with the priorities existing until the senior indebtedness is paid in full. Unless otherwise indicated in the applicable prospectus supplement, if the payments or distributions on subordinated debt securities are in the form of our securities or those of any other corporation under a plan of reorganization or readjustment and are subordinated to outstanding senior indebtedness and to any securities issued with respect to senior indebtedness under such a plan, they will be made to the holders of the subordinated debt securities (Section 17.3 of the subordinated indenture). No holder of any senior indebtedness will be prejudiced in the right to enforce the subordination of subordinated debt securities by any act or failure to act on the part of us. (Section 17.9 of the subordinated indenture).

Senior indebtedness will only be deemed to have been paid in full if the holders of that indebtedness have received cash, securities or other property which is equal to the amount of the outstanding senior indebtedness.

11

After payment in full of all present and future senior indebtedness, holders of subordinated debt securities will be subrogated to the rights of any holders of senior indebtedness to receive any further payments or distributions that are applicable to the senior indebtedness until all the subordinated debt securities are paid in full. In matters between holders of subordinated debt securities and any other type of our creditors, any payments or distributions that would otherwise be paid to holders of senior debt securities and that are made to holders of subordinated debt securities because of this subrogation will be deemed a payment by us on account of senior indebtedness and not on account of subordinated debt securities. (Section 17.7 of the subordinated indenture).

The subordinated indenture provides that the foregoing subordination provisions may be changed, except in a manner which would be adverse to the holders of subordinated debt securities of any series then outstanding. (Sections 11.1 and 11.2 of the subordinated indenture.) The prospectus supplement relating to such subordinated debt securities would describe any such change.

The prospectus supplement delivered in connection with the offering of a series of subordinated debt securities will set forth a more detailed description of the subordination provisions applicable to any such debt securities.

As of December 31, 2017, we had a carrying value of $1.252 billion of long-term debt and current maturities of long-term debt, all of which, other than $6 million, was unsecured debt that would rank equally with any senior debt securities. The secured long-term debt consisted primarily of capital leases. We will disclose material changes to this amount in any prospectus supplement relating to an offering of our debt securities. If this prospectus is being delivered in connection with the offering of a series of subordinated debt securities, the accompanying prospectus supplement or information incorporated by reference will set forth the approximate amount of indebtedness senior to such subordinated indebtedness outstanding as of a recent date. The subordinated indenture will place no limitation on the amount of additional senior indebtedness that we may incur. We expect from time to time to incur additional indebtedness constituting senior indebtedness. Except as noted above, our outstanding short-term and long-term indebtedness would rank equally with our senior debt securities and all such indebtedness would be prior in right of payment to the subordinated debt securities.

Events of Default

Unless we specify otherwise in a prospectus supplement, an event of default with respect to any series of debt securities issued under each indenture means:

12

Within 90 days after a default in respect of any series of debt securities, the trustee must give to the holders of such series notice of all uncured and unwaived defaults by us known to it. However, except in the case of a payment default, the trustee may withhold such notice if it determines that such withholding is in the interest of the holders. (Section 6.2 of each indenture).

If an event of default occurs and is continuing in respect of any outstanding series of debt securities, the trustee of the senior or subordinated indentures or the holders of at least 25% in principal amount of the outstanding debt securities of that series may declare the applicable principal amount of all of the debt securities of that series to be immediately due and payable. However, with respect to any debt securities issued under the subordinated indenture, the payment of principal and interest on such debt securities shall remain subordinated to the extent provided in Article XVII of the subordinated indenture. In addition, at any time after such a declaration of acceleration but before a judgment or decree for payment of the money due has been obtained, the holders of a majority in principal amount of outstanding debt securities of that series may, subject to specified conditions, rescind and annul such acceleration if all events of default, other than the non-payment of accelerated principal, have been cured or waived as provided in the indenture. (Section 5.2 of each indenture).

Unless we specify otherwise in a prospectus supplement, if an event of default because of certain events of bankruptcy, insolvency or receivership as described above shall occur and be continuing, then the principal amount of all the debt securities outstanding shall be and become due and payable immediately, without notice or other action by any holder or the applicable trustee, to the full extent permitted by law. (Section 5.2 of each indenture).

The holders of a majority in principal amount of the outstanding debt securities of a series, on behalf of the holders of all debt securities of that series, may waive any past default and its consequences, except that they may not waive an uncured default in payment or a default which cannot be waived without the consent of the holders of all outstanding securities of that series. (Section 5.13 of each indenture).

We must file annually with the trustee a statement, signed by specified officers, stating whether or not such officers have knowledge of any default under the indenture and, if so, specifying each such default and the nature and status of each such default. (Section 12.2 of each indenture).

Subject to provisions in the applicable indenture relating to its duties in case of default, the trustee is not required to take action at the request of any holders of debt securities, unless such holders have offered to the trustee reasonable security or indemnity. (Section 6.3 of each indenture).

Subject to indemnification requirements and other limitations set forth in the applicable indenture, the holders of a majority in principal amount of the outstanding debt securities of any series may direct the time, method and place of conducting proceedings for remedies available to the trustee, or exercising any trust or power conferred on the trustee, in respect of such series. (Section 5.12 of each indenture).

Defeasance; Satisfaction and Discharge

Legal or Covenant Defeasance. Each indenture provides that we may be discharged from our obligations with respect to the debt securities of any series, as described below. These provisions will apply only to any registered securities denominated and payable in U.S. dollars, unless otherwise specified in a prospectus supplement. The prospectus supplement will describe any defeasance provisions that apply to other types of debt securities. (Section 15.1 of each indenture).

At our option, we may choose one of the following alternatives:

13

In either case, we will be discharged from our obligations if we irrevocably deposit with the trustee, in trust, sufficient money and/or U.S. Government Obligations (as referred to below), in the opinion of a nationally recognized firm of independent public accountants, to pay principal, including any mandatory sinking fund payments, any premium, and interest on the debt securities of that series on the maturity of those payments in accordance with the terms of the indenture and those debt securities. This discharge may occur only if, among other things, we have delivered to the trustee an opinion of counsel or an Internal Revenue Service ruling which provides that the holders of the debt securities of that series will not recognize income, gain or loss for U.S. federal income tax purposes as a result of the defeasance. (Section 15.2 of each indenture).

In addition, with respect to the subordinated indenture, in order to be discharged, no event or condition shall exist that, pursuant to certain provisions described under “Subordination of the Subordinated Debt Securities” above, would prevent us from making payments of principal of, and any premium and interest on subordinated debt securities and coupons at the date of the irrevocable deposit referred to above. (Section 15.2 of the subordinated indenture).

Covenant Defeasance and Events of Default. In the event we exercise our option to effect covenant defeasance with respect to any series of debt securities and the debt securities of that series are declared due and payable because of the occurrence of any event of default, the amount of money and/or U.S. Government Obligations on deposit with the trustee will be sufficient to pay amounts due on the debt securities of that series on the dates installments of interest or principal are due but may not be sufficient to pay amounts due on the debt securities of that series at the time of the acceleration resulting from the event of default. However, we will remain liable for those payments.

“U.S. Government Obligations” generally means securities which are (1) direct obligations of the United States backed by its full faith and credit, or (2) obligations of a person controlled or supervised by and acting as an agency or instrumentality of the United States, the payment of which is unconditionally guaranteed as a full faith and credit obligation by the United States, which, in either case, are not callable or redeemable at the option of the issuer thereof, and will also include certain depository receipts. (Section 15.2 of each indenture).

We may exercise our legal defeasance option even if we have already exercised our covenant defeasance option. (Section 15.2 of each indenture).

There may be additional provisions relating to defeasance which we will describe in the applicable prospectus supplement. (Section 15.1 of each indenture).

Conversion or Exchange

Any series of the debt securities may be convertible or exchangeable into common or preferred stock or other debt securities registered under the registration statement relating to this prospectus or other property or securities of us or other securities or property of another issuer. The specific terms and conditions on which such debt securities may be so converted or exchanged will be set forth in the applicable prospectus supplement.

Those terms may include the conversion or exchange price, provisions for conversion or exchange, either mandatory, at the option of the holder, or at our option, whether we have an option to convert debt securities into cash, rather than common stock, and provisions under which the number of shares of common or preferred stock or other securities to be received by the holders of debt securities would be calculated as of a time and in the manner stated in the applicable prospectus supplement. (Sections 3.1 and 16.1 of each indenture).

Notices to Registered Holders

Notices to registered holders of debt securities will be sent by mail to the addresses of those holders as they appear in the security register. (Section 1.5 of each indenture).

Replacement of Securities

We will replace any mutilated debt security at the expense of the holder upon surrender of the mutilated debt security to the trustee in the circumstances described in the indenture. We will replace debt securities that are destroyed, stolen or lost at the expense of the holder upon delivery to the trustee of evidence of the destruction, loss or theft of the debt securities satisfactory to us and to the trustee in the circumstances described in the indenture. In the case of a destroyed, lost or stolen debt security, an indemnity satisfactory to the trustee and us may be required at the expense of the holder of the debt security before a replacement debt security will be issued. (Section 3.6 of each indenture).

Governing Law

The indentures and the debt securities will be governed by, and construed in accordance with, the internal laws of the State of New York. (Section 1.11 of each indenture).

Regarding the Trustee

U.S. Bank National Association is trustee under the senior indenture and unless otherwise specified in the applicable prospectus supplement, is expected to act as trustee under the subordinated indenture. U.S. Bank is a lender under our primary credit facility and is also a trustee for certain of our other debt instruments. From time to time, we may also enter into other banking or other relationships with U.S. Bank or its affiliates.

If a trustee is or becomes one of our creditors, the indenture limits the right of the trustee to obtain payment of claims in certain cases, or to realize on certain property received in respect of any such claims as security or otherwise. The trustee will be permitted to engage in other transactions. However, if after a specified default has occurred and is continuing, it acquires or has a conflicting interest (such as continuing to serve as trustee with respect to outstanding notes or debentures or continuing to be a creditor of Leggett in certain circumstances), it must eliminate such conflict within 90 days or receive permission from the SEC to continue as a trustee or resign.

There may be more than one trustee under each indenture, each with respect to one or more series of debt securities. (Section 1.1 of each indenture). Any trustee may resign or be removed with respect to one or more series of debt securities, and a successor trustee may be appointed to act with respect to such series. (Section 6.10 of each indenture).

If two or more persons are acting as trustee with respect to different series of debt securities, each trustee will be a trustee of a trust under the indenture separate from the trust administered by any other such trustee. Except as otherwise indicated in this prospectus or in an applicable prospectus supplement, any action to be taken by the trustee may be taken by each such trustee with respect to, and only with respect to, the one or more series of debt securities for which it is trustee under the indenture. (Sections 1.1 and 6.10 of each indenture).

15

Global Debt Securities

Unless we specify otherwise in a prospectus supplement for a particular series of debt securities, each series of debt securities will be issued in whole or in part in global form and will be deposited with, or on behalf of, a depositary identified in the prospectus supplement relating to that series. Global securities will be registered in the name of the depositary or its nominee, which will be the sole direct holder of the global securities. Any person wishing to own a debt security must do so indirectly through an account with a broker, bank or other financial institution that, in turn, has an account with the depositary.

Special Investor Considerations for Global Securities. Under the terms of the indentures, our obligations with respect to the debt securities, as well as the obligations of each trustee, run only to persons who are registered holders of debt securities. For example, once we make payment to the registered holder, we have no further responsibility for that payment even if the recipient is legally required to pass the payment along to an individual investor but fails to do so. As an indirect holder, an investor’s rights relating to a global security will be governed by the account rules of the investor’s financial institution and of the depositary, as well as general laws relating to transfers of debt securities.

An investor should be aware that when debt securities are issued in the form of global securities:

Neither we nor the trustees have any responsibility for any aspect of the depositary’s actions or for its records of ownership interests in the global security, and neither we nor the trustees supervise the depositary in any way.

Special Situations When the Global Security Will Be Terminated. In a few special situations described below, the global security will terminate, and interests in the global security will be exchanged for physical certificates representing debt securities. After that exchange, the investor may choose whether to hold debt securities directly or indirectly through an account at the investor’s bank or brokerage firm. In that event, investors must consult their banks or brokers to find out how to have their interests in debt securities transferred to their own names so that they may become direct holders.

The special situations where a global security is terminated are:

A prospectus supplement may list situations for terminating a global security that would apply only to a particular series of debt securities. When a global security terminates, the depositary, and not us or one of the trustees, is responsible for deciding the names of the institutions that will be the initial direct holders.

16

The Depository Trust Company. Unless otherwise indicated in the prospectus supplement, The Depository Trust Company (“DTC”), New York, NY, will act as securities depository for the debt securities. The debt securities will be issued as fully-registered securities registered in the name of Cede & Co. (DTC’s partnership nominee) or such other name as may be requested by an authorized representative of DTC. One fully-registered debt securities certificate will be issued for each issue of the debt securities, each in the aggregate principal amount of such issue, and will be deposited with DTC.

Purchases of debt securities under the DTC system must be made by or through participants, which will receive a credit for the debt securities on DTC’s records. The ownership interest of each actual purchaser of each debt security (“Beneficial Owner”) is in turn to be recorded on the participants’ records. Beneficial Owners will not receive written confirmation from DTC of their purchase. Beneficial Owners are, however, expected to receive written confirmations providing details of the transaction, as well as periodic statements of their holdings, from the participant through whom the Beneficial Owner entered into the transaction. Transfers of ownership interests in the debt securities are to be accomplished by entries made on the books of participants acting on behalf of Beneficial Owners. Beneficial Owners will not receive certificates representing their ownership interests in debt securities, except in the event that use of the book-entry system for the debt securities is discontinued.

To facilitate subsequent transfers, all debt securities deposited by participants with DTC are registered in the name of DTC’s partnership nominee, Cede & Co., or such other name as may be requested by an authorized representative of DTC. The deposit of debt securities with DTC and their registration in the name of Cede & Co. or such other DTC nominee do not affect any change in beneficial ownership. DTC has no knowledge of the actual Beneficial Owners of the debt securities; DTC’s records reflect only the identity of the direct participants to whose accounts such debt securities are credited, which may or may not be the Beneficial Owners. The participants will remain responsible for keeping account of their holdings on behalf of their customers.

Conveyance of notices and other communications by DTC to participants and by participants to Beneficial Owners will be governed by arrangements among them, subject to any statutory or regulatory requirements as may be in effect from time to time. Beneficial Owners of debt securities may wish to take certain steps to augment the transmission to them of notices of significant events with respect to the debt securities, such as redemptions, tenders, defaults, and proposed amendments to the debt securities documents. For example, Beneficial Owners of debt securities may wish to ascertain that the nominee holding the debt securities for their benefit has agreed to obtain and transmit notices to Beneficial Owners. In the alternative, Beneficial Owners may wish to provide their names and addresses to the registrar and request that copies of notices be provided directly to them.

Redemption notices shall be sent to DTC. If less than all of the debt securities within an issue are being redeemed, DTC’s practice is to determine by lot the amount of the interest of each direct participant in such issue to be redeemed.

Neither DTC nor Cede & Co. (nor any other DTC nominee) will consent or vote with respect to debt securities unless authorized by a participant in accordance with DTC’s MMI Procedures. Under its usual procedures, DTC mails an Omnibus Proxy to the Company as soon as possible after the record date. The Omnibus Proxy assigns Cede & Co.’s consenting or voting rights to those direct participants to whose accounts debt securities are credited on the record date (identified in a listing attached to the Omnibus Proxy).

Redemption proceeds, distributions, and interest payments on the debt securities will be made to Cede & Co., or such other nominee as may be requested by an authorized representative of DTC. DTC’s practice is to credit direct participants’ accounts upon DTC’s receipt of funds and corresponding detail information from the Company on the payable date in accordance with their respective holdings shown on DTC’s records. Payments by participants to Beneficial Owners will be governed by standing instructions and customary practices, as is the case with securities held for the accounts of customers in bearer form or registered in “street name,” and will be

17

the responsibility of such participant and not of DTC or the Company, subject to any statutory or regulatory requirements as may be in effect from time to time. Payment of redemption proceeds, distributions, and interest payments to Cede & Co. (or such other nominee as may be requested by an authorized representative of DTC) is the responsibility of the Company, disbursement of such payments to direct participants will be the responsibility of DTC, and disbursement of such payments to the Beneficial Owners will be the responsibility of direct and indirect participants.

A Beneficial Owner shall give notice to elect to have its debt securities purchased or tendered, through its participant and shall affect delivery of such debt securities by causing the participant to transfer the participant’s interest in the debt securities on DTC’s records. The requirement for physical delivery of debt securities in connection with an optional tender or a mandatory purchase will be deemed satisfied when the ownership rights in the debt securities are transferred by direct participants on DTC’s records and followed by a book-entry credit of the tendered debt securities to the tender agent’s DTC account.

DTC may discontinue providing its services as depository with respect to the debt securities at any time by giving reasonable notice to the Company. Under such circumstances, in the event that a successor depository is not obtained, the debt securities certificates are required to be printed and delivered.

DTC, the world’s largest securities depository, is a limited-purpose trust company organized under the New York Banking Law, a “banking organization” within the meaning of the New York Banking Law, a member of the Federal Reserve System, a “clearing corporation” within the meaning of the New York Uniform Commercial Code, and a “clearing agency” registered pursuant to the provisions of Section 17A of the Securities Exchange Act of 1934. DTC holds and provides asset servicing for over 3.5 million issues of U.S. and non-U.S. equity issues, corporate and municipal debt issues, and money market instruments (from over 100 countries) that DTC’s direct participants deposit with DTC. DTC also facilitates the post-trade settlement among direct participants of sales and other securities transactions in deposited securities, through electronic computerized book-entry transfers and pledges between direct participants’ accounts. This eliminates the need for physical movement of debt securities certificates. Direct participants include both U.S. and non-U.S. securities brokers and dealers, banks, trust companies, clearing corporations, and certain other organizations. DTC is a wholly-owned subsidiary of The Depository Trust & Clearing Corporation (“DTCC”). DTCC is the holding company for DTC, National Securities Clearing Corporation and Fixed Income Clearing Corporation, all of which are registered clearing agencies. DTCC is owned by the users of its regulated subsidiaries. Access to the DTC system is also available to others such as both U.S. and non-U.S. securities brokers and dealers, banks, trust companies, and clearing corporations that clear through or maintain a custodial relationship with a direct participant, either directly or indirectly. The DTC Rules applicable to its participants are on file with the SEC. More information about DTC can be found at www.dtcc.com.

The information in this section concerning DTC and DTC’s book-entry system has been obtained from sources that the Company believes to be reliable, but the Company takes no responsibility for the accuracy thereof.

Rights Upon Liquidation. In the event of our voluntary or involuntary liquidation, dissolution, or winding up, the holder of common stock will be entitled to share equally in our assets available for distribution after payment in full of all debts and after the holders of preferred stock have received their liquidation preferences in full.

Miscellaneous. Once shares of common stock are fully paid, they are non-assessable. Also, the shares are not redeemable and have no subscription, conversion or preemptive rights.

All of the terms of the preferred stock are, or will be contained in our Articles of Incorporation or in one or more certificates of designation relating to each series of the preferred stock, which will be filed with the SEC at or prior to the issuance of the series of preferred stock.

Our Articles of Incorporation vest our board of directors with authority to issue up to 100,000,000 shares of preferred stock, no par value per share, from time to time in one or more classes and one or more series, with such voting powers, full or limited, or no voting powers, and such designations, preferences and relative, participating, optional or other special rights, and qualifications, limitations or restrictions thereof, as may be stated in the resolutions providing for the issuance of such stock adopted by our board of directors.

DESCRIPTION OF DEPOSITARY SHARES

The description of certain provisions of any deposit agreement and any related depositary shares and depositary receipts in this prospectus and in any prospectus supplement are summaries of the material provisions of that deposit agreement and of the depositary shares and depositary receipts. These descriptions do not restate those agreements and do not contain all of the information that you may find useful. We urge you to read the applicable agreements because they, and not the summaries, define many of your rights as a holder of the depositary shares. For more information, please review the form of deposit agreement and form of depositary receipts relating to each series of the preferred stock, which will be filed with the SEC promptly after the offering of that series of preferred stock and will be available as described under the heading “Where You Can Find More Information.”

The applicable prospectus supplement will also state whether any of the generalized provisions summarized below do not apply to the depositary shares or depositary receipts being offered.

General

We may elect to have shares of preferred stock represented by depositary shares. The shares of any series of the preferred stock underlying the depositary shares will be deposited under a separate deposit agreement between us and a bank or trust company that we select. The prospectus supplement relating to a series of depositary shares will set forth the name and address of this preferred stock depositary. Subject to the terms of the deposit agreement, each owner of a depositary share will be entitled, proportionately, to all the rights, preferences and privileges of the preferred stock represented by such depositary share, including dividend, voting, redemption, conversion, exchange and liquidation rights.

The depositary shares will be evidenced by depositary receipts issued pursuant to the deposit agreement, each of which will represent the applicable interest in a number of shares of a particular series of the preferred stock described in the applicable prospectus supplement.

A holder of depositary shares will be entitled to receive the shares of preferred stock, but only in whole shares of preferred stock, underlying those depositary shares. If the depositary receipts delivered by the holder evidence a number of depositary shares in excess of the whole number of shares of preferred stock to be withdrawn, the depositary will deliver to that holder at the same time a new depositary receipt for the excess number of depositary shares.

20

Dividends and Other Distributions

The preferred stock depositary will distribute all cash dividends or other cash distributions in respect of the series of preferred stock represented by the depositary shares to the record holders of depositary receipts in proportion, to the extent possible, to the number of depositary shares owned by those holders. The depositary, however, will distribute only the amount that can be distributed without attributing to any depositary share a fraction of one cent, and any undistributed balance will be added to and treated as part of the next sum received by the depositary for distribution to record holders of depositary receipts then outstanding.

If there is a distribution other than in cash in respect of the preferred stock, the preferred stock depositary will distribute property received by it to the record holders of depositary receipts in proportion, insofar as possible, to the number of depositary shares owned by those holders, unless the preferred stock depositary determines that it is not feasible to make such a distribution. In that case, the preferred stock depositary may, with our approval, adopt any method that it deems equitable and practicable to effect the distribution, including a public or private sale of the property and distribution of the net proceeds from the sale to the holders.

The amount distributed in any of the above cases will be reduced by any amount we or the preferred stock depositary are required to withhold on account of taxes.

Conversion and Exchange

If any series of preferred stock underlying the depositary shares is subject to provisions relating to its conversion or exchange as set forth in an applicable prospectus supplement, each record holder of depositary receipts will have the right or obligation to convert or exchange the depositary shares evidenced by the depositary receipts pursuant to those provisions.

Redemption of Depositary Shares

If any series of preferred stock underlying the depositary shares is subject to redemption, the depositary shares will be redeemed from the proceeds received by the preferred stock depositary resulting from the redemption, in whole or in part, of the preferred stock held by the preferred stock depositary. Whenever we redeem a share of preferred stock held by the preferred stock depositary, the preferred stock depositary will redeem as of the same redemption date a proportionate number of depositary shares representing the shares of preferred stock that were redeemed. The redemption price per depositary share will be equal to the aggregate redemption price payable with respect to the number of shares of preferred stock underlying the depositary shares. If fewer than all the depositary shares are to be redeemed, the depositary shares to be redeemed will be selected by lot or proportionately as we may determine.

After the date fixed for redemption, the depositary shares called for redemption will no longer be deemed to be outstanding and all rights of the holders of the depositary shares will cease, except the right to receive the redemption price. Any funds that we deposit with the preferred stock depositary relating to depositary shares which are not redeemed by the holders of the depositary shares will be returned to us after a period of two years from the date the funds are deposited by us.

Voting

Upon receipt of notice of any meeting at which the holders of any shares of preferred stock underlying the depositary shares are entitled to vote, the preferred stock depositary will mail the information contained in the notice to the record holders of the depositary receipts. Each record holder of the depositary receipts on the record date, which will be the same date as the record date for the preferred stock, may then instruct the preferred stock depositary as to the exercise of the voting rights pertaining to the number of shares of preferred stock underlying that holder’s depositary shares. The preferred stock depositary will try to vote the number of shares of preferred

21

stock underlying the depositary shares in accordance with the instructions, and we will agree to take all reasonable action which the preferred stock depositary deems necessary to enable the preferred stock depositary to do so. The preferred stock depositary will abstain from voting the preferred stock to the extent that it does not receive specific written instructions from holders of depositary receipts representing the preferred stock.

Record Date

Subject to the provisions of the deposit agreement, whenever:

Withdrawal of Preferred Stock

Upon surrender of depositary receipts at the principal office of the preferred stock depositary, upon payment of any unpaid amount due the preferred stock depositary, and subject to the terms of the deposit agreement, the owner of the depositary shares evidenced by the depositary receipts is entitled to delivery of the number of whole shares of preferred stock and all money and other property, if any, represented by the depositary shares. Partial shares of preferred stock will not be issued. If the depositary receipts delivered by the holder evidence a number of depositary shares in excess of the number of depositary shares representing the number of whole shares of preferred stock to be withdrawn, the preferred stock depositary will deliver to the holder at the same time a new depositary receipt evidencing the excess number of depositary shares. Holders of preferred stock that are withdrawn will not be entitled to deposit the shares that have been withdrawn under the deposit agreement or to receive depositary receipts.

Amendment and Termination of the Deposit Agreement

We and the preferred stock depositary may at any time agree to amend the form of depositary receipt and any provision of the deposit agreement. However, any amendment that materially and adversely alters the rights of holders of depositary shares will not be effective unless the amendment has been approved by the holders of at least a majority of the depositary shares then outstanding. The deposit agreement may be terminated by us or by the preferred stock depositary only if all outstanding shares have been redeemed or if a final distribution in respect of the underlying preferred stock has been made to the holders of the depositary shares in connection with our liquidation, dissolution or winding up.

Charges of Preferred Stock Depositary

We will pay all charges of the preferred stock depositary including charges in connection with the initial deposit of the preferred stock, the initial issuance of the depositary receipts, the distribution of information to the

22

holders of depositary receipts with respect to matters on which preferred stock is entitled to vote, withdrawals of the preferred stock by the holders of depositary receipts or redemption or conversion of the preferred stock, except for taxes (including transfer taxes, if any) and other governmental charges and any other charges expressly provided in the deposit agreement to be at the expense of holders of depositary receipts or persons depositing preferred stock.

Miscellaneous

Neither we nor the preferred stock depositary will be liable if either of us is prevented or delayed by law or any circumstance beyond our control in performing any obligations under the deposit agreement. The obligations of the preferred stock depositary under the deposit agreement are limited to performing its duties under the agreement without negligence or bad faith. Our obligations under the deposit agreement are limited to performing our duties in good faith. Neither we nor the preferred stock depositary is obligated to prosecute or defend any legal proceeding in respect of any depositary shares or preferred stock unless satisfactory indemnity is furnished. We and the preferred stock depositary may rely on advice of or information from counsel, accountants or other persons that they believe to be competent and on documents that they believe to be genuine.

The preferred stock depositary may resign at any time or be removed by us, effective upon the acceptance by its successor of its appointment. If we have not appointed a successor preferred stock depositary and the successor depositary has not accepted its appointment within 60 days after the preferred stock depositary delivered a resignation notice to us, the preferred stock depositary may terminate the deposit agreement. See “Amendment and Termination of the Deposit Agreement” above.

The price per security and the number of securities may be fixed at the time the purchase contracts are issued or may be determined by reference to a specific formula stated in the purchase contracts. The purchase contracts may require us to make periodic payments to the holders of the purchase contracts. The payments may be unsecured or prefunded on some basis to be specified in the applicable prospectus supplement.

Each series of rights will be issued under a separate rights agreement which we will enter into with a bank or trust company, as rights agent, all as set forth in the applicable prospectus supplement.

PART II

INFORMATION NOT REQUIRED IN PROSPECTUS

Item 14. Other Expenses of Issuance and Distribution.

The following table sets forth the estimated expenses in connection with the issuance and distribution of the securities being registered, other than underwriting discounts and commissions. Other than the SEC registration fee, all the amounts listed are estimates.

Item 15. Indemnification of Directors and Officers.

The Company is a Missouri corporation. Sections 351.355(1) and (2) of The General and Business Corporation Law of the State of Missouri (“GBCL”) provide that a corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding by reason of the fact that he or she is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by him or her in connection with such action, suit or proceeding if he or she acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the corporation and, with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful, except that, in the case of an action or suit by or in the right of the corporation, no person shall be indemnified as to any claim, issue or matter as to which such person shall have been adjudged to be liable for negligence or misconduct in the performance of his or her duty to the corporation, unless and only to the extent that the court in which the action or suit was brought determines upon application that such person is fairly and reasonably entitled to indemnity for proper expenses.

Section 351.355(3) of the GBCL provides that, except as otherwise provided in the corporation’s articles of incorporation or the bylaws, to the extent a director, officer, employee or agent of the corporation has been successful in the defense of any such action, suit or proceeding or any claim, issue or matter therein, he or she shall be indemnified against expenses, including attorney’s fees, actually and reasonably incurred in connection with such action, suit or proceeding.

Section 351.355(5) of the GBCL provides that expenses incurred in defending any civil, criminal, administrative or investigative action, suit or proceeding may be paid by the corporation in advance of the final disposition of the action, suit, or proceeding as authorized by the board of directors in the specific case upon receipt of an undertaking by or on behalf of the director, officer, employee or agent to repay such amount unless it shall ultimately be determined that he or she is entitled to be indemnified by the corporation as authorized in this section.

28

Section 351.355(7) of the GBCL provides that a corporation may provide additional indemnification to any person indemnifiable under subsection (1) or (2), provided such additional indemnification is authorized by the corporation’s articles of incorporation or an amendment thereto or by a shareholder-approved bylaw or agreement, provided further that no person shall thereby be indemnified against conduct which was finally adjudged to have been knowingly fraudulent, deliberately dishonest or willful misconduct.

Section 351.355(8) of the GBCL provides that a corporation may purchase and maintain insurance or another arrangement on behalf of any person who is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against any liability asserted against him or her and incurred by him or her in any such capacity, or arising out of his or her status as such, whether or not the corporation would have the power to indemnify him or her against such liability under the provisions of that section. The insurance or other arrangement, including a trust fund, self-insurance, letters of credit, guaranty or surety arrangement, may be procured within the corporation or with any insurer or other person deemed appropriate by the board of directors. That section also provides that in the absence of fraud the judgment of the board of directors as to the terms and conditions of the insurance or other arrangement and the identity of the insurer or other person participating in an arrangement shall be conclusive and the insurance or arrangement shall not be voidable and shall not subject the directors approving the insurance or arrangement to liability on any ground regardless of whether directors participating in the approval are beneficiaries of the insurance arrangement.

The Company’s restated articles of incorporation, as amended, and bylaws generally provide that each person who was or is a director or officer of the corporation shall be indemnified by the corporation as a matter of right to the fullest extent permitted or authorized by applicable law and as otherwise provided in its restated articles of incorporation. For this purpose, “applicable law” generally means Section 351.355 of the GBCL, including any amendments since May 7, 1986, but only to the extent such amendment permits the corporation to provide broader indemnification rights. The Company’s bylaws also provide that each person who was or is an employee or agent of the corporation, or who was or is serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership or other enterprise may, at the discretion of the board of directors, be indemnified by the corporation to the same extent as provided in the bylaws for directors and officers. The Company’s restated articles of incorporation also provide that the indemnification and other rights provided by the restated articles of incorporation will not be deemed exclusive of any other rights to which a director or officer may be entitled under any by-law, agreement, vote of shareholders or disinterested directors or otherwise, both as to action in such person’s official capacity and as to action in any other capacity while holding the office of director or officer, and the corporation is specifically authorized to provide such indemnification and other rights by any by-law, agreement, vote of shareholders or disinterested directors or otherwise. The Company has a similar provision in its bylaws.

The Company’s restated articles of incorporation provide that expenses incurred by any person who was or is a director or officer in defending generally any proceeding (including those by or in the right of the Company) shall be promptly advanced by the Company when so requested at any time, but only if the requesting person delivers to the Company an undertaking to repay to the Company all amounts so advanced if it should ultimately be determined that the requesting person is not entitled to be indemnified under the Company’s restated articles of incorporation, bylaws, state law or otherwise. The Company has a similar provision in its bylaws.

In addition, the Company has entered into indemnification agreements, approved by its shareholders, with its directors and executive officers. Pursuant to those agreements, the Company has agreed to indemnify and hold harmless each indemnitee to the fullest extent permitted or authorized by applicable law. For this purpose, “applicable law” generally means Section 351.355 of the GBCL, including any amendments since May 7, 1986, but only to the extent such amendment permits the corporation to provide broader indemnification rights. In addition, the Company has agreed to further indemnify and hold harmless each such party who was or is a party or is threatened to be made party to any proceeding, including any proceeding by or in the right of the Company,

29

by reason of the fact that the indemnitee is or was a director, officer, employee or agent of the Company, or is or was serving at the request or on the behalf of the Company as a director, officer, employee or agent of another enterprise or by reason of anything done or not done by him or her in any such capacities. However, under these agreements, the Company will not provide indemnification: (i) for amounts indemnified by the Company outside of the agreement or paid pursuant to insurance; (ii) in respect of remuneration paid to indemnitee if determined finally that such remuneration was in violation of law; (iii) on account of any suit for any accounting of profits pursuant to Section 16(b) of the Securities Exchange Act of 1934 or similar provisions of any federal, state or local law; (iv) on account of indemnitee’s conduct which is finally adjudged to have been knowingly fraudulent, deliberately dishonest or willful misconduct; or (v) if a final adjudication shall determine that such indemnification is not lawful.

The Company’s restated articles of incorporation provide that the corporation may purchase and maintain insurance on behalf of any person who was or is a director, officer, employee or agent of the corporation, or was or is serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership or other enterprise against any liability asserted against or incurred by such person in any such capacity, or arising out of his or her status as such, whether or not the corporation would have the power to indemnify such person against such liability. The Company insures its directors and officers against certain liabilities and has insurance against certain payments which it may be obliged to make to such persons under the indemnification provisions of its restated articles of incorporation. This insurance may provide broader coverage for such individuals than may be required by the provisions of the restated articles of incorporation.

The foregoing represents a summary of the general effect of the indemnification provisions of the GBCL, the restated articles of incorporation, as amended, the bylaws and such agreements and insurance. Additional information regarding indemnification of directors and officers can be found in Section 351.355 of the GBCL, the restated articles of incorporation, as amended, the bylaws and any pertinent agreements.

The forms of Underwriting Agreement to be filed as Exhibits 1.1 to 1.7 to this registration statement will provide for the mutual indemnification of the Company and any Underwriters, their respective controlling persons, directors and certain of their officers, against certain liabilities, including liabilities under the Securities Act of 1933, as amended.

Item 16. Exhibits.

EXHIBIT INDEX

31

Item 17. Undertakings.

The undersigned registrant hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i) To include any prospectus required by section 10(a)(3) of the Securities Act of 1933;

(ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement;

(iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

Provided, however, that: paragraphs (i), (ii) and (iii) above do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the registrant pursuant to section 13 or section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

32

(2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(4) That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser:

(A) Each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

(B) Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) for the purpose of providing the information required by section 10(a) of the Securities Act of 1933 shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.

(5) That, for the purpose of determining liability of the registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities, the undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(i) Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

(ii) Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

(iii) The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

(iv) Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

(6) That, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual report pursuant to section 13(a) or section 15(d) of the Securities Exchange Act of 1934 that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

33

(7) To supplement the prospectus, after the expiration of the subscription period, to set forth the results of the subscription offer, the transactions by the underwriters during the subscription period, the amount of unsubscribed securities to be purchased by the underwriters, and the terms of any subsequent reoffering thereof. If any public offering by the underwriters is to be made on terms differing from those set forth on the cover page of the prospectus, a post-effective amendment will be filed to set forth the terms of such offering.

(8) To file an application for the purpose of determining the eligibility of the trustee to act under subsection (a) of section 310 of the Trust Indenture Act (“Act”) in accordance with the rules and regulations prescribed by the Commission under section 305(b)(2) of the Act.

(9) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.
