Offer to Exchange up to $720,000,000 Principal Amount of 9.75% Senior Notes due 2023 for a Like Principal Amount of 9.75% Senior Notes due 2023 which are registered under the Securities Act of 1933 (the “2023 Notes Exchange Offer”); and

Blue Cube Spinco Inc. (“Blue Cube” or the “Issuer”), a wholly-owned subsidiary of Olin Corporation (“Olin” or the “Parent Guarantor”), is offering to exchange (i) up to $720,000,000 aggregate principal amount of its outstanding, unregistered 9.75% Senior Notes due 2023 (the “Original 2023 Notes”) for an equivalent amount of registered 9.75% Senior Notes due 2023 (the “Exchange 2023 Notes”) and (ii) up to $500,000,000 aggregate principal amount of its outstanding, unregistered 10.00% Senior Notes due 2025 (the “Original 2025 Notes” and, together with the Original 2023 Notes, the “Original Notes” and each an “Original Note”) for an equivalent amount of registered 10.00% Senior Notes due 2025 (the “Exchange 2025 Notes” and, together with the Exchange 2023 Notes, the “Exchange Notes” and each an “Exchange Note”). The Original Notes and the Exchange Notes are sometimes referred to in this prospectus together as the “Notes.” The terms of the Exchange Notes are identical in all material respects to the terms of the corresponding series of the Original Notes, except that the Exchange Notes are registered under the Securities Act of 1933, as amended (the “Securities Act”), and the transfer restrictions, registration rights and payment of additional interest in case of non-registration applicable to the Original Notes do not apply to the Exchange Notes. For a more detailed description of the Exchange Notes, see “Description of Notes.” The Original Notes may only be tendered in minimum denominations of $2,000 in principal or in integral multiples of $1,000 in excess thereof. The exchange offers will expire at 11:59 p.m., New York City time, on , 2016, subject to our right to extend the expiration date for any exchange offer. Upon expiration of the exchange offers, all outstanding Original Notes that are validly tendered and not properly withdrawn will be exchanged for a like principal amount of the applicable series of the Exchange Notes. You may withdraw tendered Original Notes at any time prior to the expiration date.

The Original Notes are, and the Exchange Notes will be, fully and unconditionally guaranteed on a senior unsecured basis by Olin. All references to the Notes include references to the related guarantees. The Exchange Notes will not be listed on any securities exchange or any automated dealer quotation system and there is currently no market for the Exchange Notes.

Each broker-dealer that receives Exchange Notes for its own account pursuant to an exchange offer must acknowledge that it will deliver a prospectus in connection with any resale of such Exchange Notes. This prospectus, as it may be amended or supplemented from time to time, may be used by a broker-dealer in connection with resales of Exchange Notes received in exchange for Original Notes where such Original Notes were acquired by such broker-dealer as a result of market-making activities or other trading activities. The letter of transmittal states that by so acknowledging and by delivering (or making available) a prospectus, a broker-dealer will not be deemed to admit that it is an “underwriter” within the meaning of the Securities Act. We have agreed that, for a period of up to 180 days after the expiration date, we will make this prospectus, as amended and supplemented, available to any broker-dealer for use in connection with any such resale. See “Plan of Distribution.”

Investing in the Notes involves risks. See “Risk Factors” beginning on page 11 for a discussion of certain risks that you should consider in connection with the exchange offers and an investment in the Notes.

Neither the Securities and Exchange Commission (the “SEC” or the “Commission”) nor any state securities commission has approved or disapproved of these securities or passed upon the adequacy or accuracy of this prospectus. Any representation to the contrary is a criminal offense.

This prospectus contains and incorporates by reference “forward-looking statements.” We use words such as “could,” “may,” “might,” “will,” “expect,” “likely,” “believe,” “continue,” “anticipate,” “estimate,” “intend,” “plan,” “project” and other similar expressions to identify some forward-looking statements, but not all forward-looking statements include these words. All of our forward-looking statements involve estimates and uncertainties that could cause actual results to differ materially from those expressed in the forward-looking statements. Accordingly, any such statements are qualified in their entirety by reference to the information described under the section entitled “Risk Factors” in this prospectus and in Olin’s Annual Report on Form 10-K for the fiscal year ended December 31, 2015 incorporated by reference herein.

The forward-looking statements contained or incorporated by reference in this prospectus are based on assumptions that we have made in light of our industry experience and our perceptions of historical trends, current conditions, expected future developments and other factors we believe are appropriate under the circumstances. As you read and consider this prospectus, you should understand that these statements are not guarantees of performance or results. They involve risks, uncertainties (many of which are beyond our control) and assumptions. Although we believe that these forward-looking statements are based on reasonable assumptions, you should be aware that many factors could affect our actual operating and financial performance and cause our performance to differ materially from the performance anticipated in the forward-looking statements. We believe these factors include, but are not limited to, those described under the section entitled “Risk Factors” in this prospectus and in Olin’s Annual Report on Form 10-K for the fiscal year ended December 31, 2015 incorporated by reference herein, and those described in the section entitled “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in each of Olin’s Annual Report on Form 10-K for the fiscal year ended December 31, 2015 and Olin’s subsequent Quarterly Reports on Form 10-Q each incorporated by reference herein. Should one or more of these risks or uncertainties materialize, or should any of these assumptions prove incorrect, our actual operating and financial performance may vary in material respects from the performance projected in these forward-looking statements.

Further, any forward-looking statement speaks only as of the date on which it is made, and except as required by law, we undertake no obligation to update any forward-looking statement contained in this prospectus to reflect events or circumstances after the date on which it is made or to reflect the occurrence of anticipated or unanticipated events or circumstances. New factors that could cause our business not to develop as we expect emerge from time to time, and it is not possible for us to predict all of them. Further, we cannot assess the impact of each currently known or new factor on our results of operations or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements.

This prospectus and documents incorporated by reference herein include market share, ranking, industry data and forecasts that we obtained from industry publications, surveys, public filings and internal company sources. Industry publications, surveys and forecasts generally state that the information contained therein has been obtained from sources believed to be reliable, but there can be no assurance as to the accuracy or completeness of included information. We have not independently verified any of the data from third-party sources, nor have we ascertained the underlying economic assumptions relied upon therein. Statements as to our market position and ranking are based on market data currently available to us, management’s estimates and assumptions we have made regarding the size of our markets within our industry. Some market data and statistical information are also based on our good faith estimates, which are derived from management’s knowledge of our industry and independent sources. This information may prove to be inaccurate because of the method by which we obtain some of the data for our estimates or because this information cannot always be verified with complete certainty due to the limits on the availability and reliability of data and other limitations and uncertainties. In addition, while we believe the market position and ranking information included herein is generally reliable, such information is inherently imprecise. While we are not aware of any misstatements regarding our industry data presented herein, our estimates involve risks and uncertainties and are subject to change based on various factors, including those discussed under the heading “Risk Factors” in this prospectus and in Olin’s Annual Report on Form 10-K for the fiscal year ended December 31, 2015 incorporated by reference herein.

Blue Cube is a wholly-owned subsidiary of Olin that holds DCP through its subsidiaries, and all of its assets consist of direct and indirect ownership interest in, and all of its business is conducted through, its subsidiaries.

Acquisition of the Dow Chlorine Products Business

On October 5, 2015 (the “Closing Date”), Olin acquired from TDCC the Acquired Business using a Reverse Morris Trust Structure (collectively, the “Acquisition”). The Acquired Business’s operating results are included in Olin’s financial statements since the Closing Date of the Acquisition. For segment reporting purposes, the Acquired Business’s Global Epoxy operating results comprise Olin’s newly created Epoxy segment and the Acquired Business’s U.S. Chlor Alkali and Vinyl and Global Chlorinated Organics (Acquired Chlor Alkali Business) operating results, combined with Olin’s former Chlor Alkali Products and Chemical Distribution segments, comprise Olin’s newly created Chlor Alkali Products and Vinyls segment.

The Business

We are a manufacturer concentrated in three business segments: Chlor Alkali Products and Vinyls, Epoxy and Winchester. The Chlor Alkali Products and Vinyls segment manufactures and sells chlorine and caustic soda, ethylene dichloride and vinyl chloride monomer, methyl chloride, methylene chloride, chloroform, carbon tetrachloride, perchloroethylene, trichloroethylene and vinylidene chloride, hydrochloric acid, hydrogen, bleach products and potassium hydroxide, which represented $704.3 million in sales for the first quarter 2016. The Epoxy segment produces and sells a full range of epoxy materials, including allyl chloride, epichlorohydrin, liquid epoxy resins and downstream products such as converted epoxy resins and additives, which represented $460.2 million in sales for the first quarter of 2016. The Winchester segment produces and sells sporting ammunition, reloading components, small caliber military ammunition and components, and industrial cartridges, which represented $183.7 million in sales for the first quarter of 2016. For the three months ended March 31, 2016, we generated $1,348.2 million of sales and a net loss of $37.9 million, which includes $92.8 million of pre-tax restructuring charges.

Summary of the Terms of the Exchange Offers

Background

The Original 2023 Notes and the Original 2025 Notes were issued in a private placement in connection with the Acquisition. In connection with such private placement of the Original 2023 Notes and the Original 2025 Notes, we entered into a registration rights agreement in which we agreed, among other things, to complete the exchange offers. See “The Exchange Offers—Purpose of the Exchange Offers; Registration Rights.”

The Exchange Offers

We are offering to exchange:

the unregistered Original 2023 Notes for an equivalent amount of the Exchange 2023 Notes, which are registered under the Securities Act; and

the unregistered Original 2025 Notes for an equivalent amount of the Exchange 2025 Notes, which are registered under the Securities Act.

The Original Notes may only be tendered in minimum denominations of $2,000 in principal or in integral multiples of $1,000 in excess thereof. In order to exchange an Original Note, you must follow the required procedures described herein, and we must accept the Original Note for exchange. We will exchange all Original Notes validly tendered and not properly withdrawn prior to the expiration date. See “The Exchange Offers.”

Resale of Exchange Notes and Required Representations

Based on interpretations of the SEC staff, as described in previous no-action letters issued to third parties, we believe that the Exchange Notes you receive pursuant to the exchange offers in exchange for the Original Notes may be offered for resale, resold and otherwise transferred without compliance with the registration and prospectus delivery provisions of the Securities Act, provided that the requirements in clauses (i)-(iii) below are satisfied. In addition, as a condition to your participation in the exchange offers, you will be required to represent to the Issuer and the Parent Guarantor that:

(i)

you are acquiring the Exchange Notes in the exchange offers in the ordinary course of your business;

(ii)

you have no arrangement or understanding with any person, and do not intend, to participate in the distribution (within the meaning of the Securities Act) of the Exchange Notes you will receive in the exchange offers in violation of the Securities Act;

(iii)

you are not an “affiliate” (as defined in Rule 405 under the Securities Act) of the Issuer or the Parent Guarantor;

(iv)

if you are a broker-dealer that will receive Exchange Notes for your own account in exchange for Original Notes that were acquired as a result of market-making or other trading

activities, then you will deliver a prospectus (or, to the extent permitted by law, make available a prospectus to purchasers) in connection with any resale of any such Exchange Note; and

(v)

you are not acting on behalf of any person who, to your knowledge, could not truthfully make the representations in clauses (i)-(iv) above.

By tendering your Original Notes as described in “The Exchange Offers—Procedures for Tendering,” you will be making representations to this effect. If you fail to satisfy any of the representations in clauses (i)-(iii) above, you cannot rely on the position of the SEC set forth in the no-action letters referred to above and you must comply with the registration and prospectus delivery requirements of the Securities Act in connection with a resale of the Exchange Notes.

We base our belief on interpretations by the SEC staff in no-action letters issued to other issuers in exchange offers like ours. We cannot guarantee that the SEC would make a similar decision about our exchange offers. If our belief is wrong, you could incur liability under the Securities Act. We will not protect you against any loss incurred as a result of this liability under the Securities Act.

We have agreed that, for a period of up to 180 days after the expiration date, we will make this prospectus, as amended and supplemented, available to any broker-dealer for use in connection with any such resale. See “Plan of Distribution.”

Consequences if You Do Not Exchange Your Original Notes

Original Notes that are not tendered in the exchange offers or are not accepted for exchange will continue to be subject to transfer restrictions. In general, you will not be able to offer or sell such Original Notes unless you are able to rely on an exemption from the requirements of the Securities Act, or the Original Notes are registered under the Securities Act. The Original Notes not tendered will remain outstanding and continue to accrue interest but will not retain any rights under the Registration Rights Agreement except as otherwise specified therein.

After the exchange offers are completed, we will no longer have an obligation to register the Original Notes, except under limited circumstances. To the extent that Original Notes are tendered and accepted in the exchange offers, the market for any remaining Original Notes may be adversely affected. See “Risk Factors—Risks Relating to the Notes and the Exchange Offers—If you fail to exchange your Original Notes, they will continue to be restricted securities and may become less liquid.”

Expiration Date

Each exchange offer expires at 11:59 p.m., New York City time, on , 2016 subject to our right to extend the expiration date

for either or both of the exchange offers. See “The Exchange Offers—Expiration Date; Extensions; Amendments.”

Issuance of Exchange Notes

We will issue Exchange Notes in exchange for Original Notes validly tendered and not properly withdrawn, and accepted in the exchange offers promptly following the expiration date (unless terminated as described in this prospectus). See “The Exchange Offers—Terms of the Exchange Offers.”

Conditions to the Exchange Offers

The exchange offers are subject to certain customary conditions, which we may amend or waive. The exchange offers are not conditioned upon any minimum principal amount of outstanding Original Notes being tendered. See “The Exchange Offers—Conditions to the Exchange Offers.”

Procedures for Tendering Your Original Notes

To participate in the exchange offers, you must, on or prior to the Expiration Date, (i) complete, sign and date the accompanying letter of transmittal provided to you with this prospectus, or a facsimile copy of such letter, and have the signature thereto guaranteed if required by such letter, in accordance with its instructions and the instructions of this prospectus, and (ii) mail or otherwise deliver the executed letter of transmittal, together with your Original Notes and any other required documentation to U.S. Bank National Association, the exchange agent, as specified in the letter of transmittal.

If you are a broker, dealer, commercial bank, trust company or other nominee and you hold Original Notes through the Depository Trust Company (“DTC”), and wish to participate in the exchange offers, you must do so pursuant to DTC’s automated tender offer program.

Holders who hold their positions, directly or indirectly, through the Euroclear Bank SA/NV (“Euroclear”) or Clearstream Banking, société anonyme (“Clearstream”) must adhere to the procedures of Euroclear or Clearstream as applicable, and the procedures described in this prospectus. See “The Exchange Offers—Procedures for Tendering.”

Special Procedures for Beneficial Holders

If you beneficially own Original Notes which are registered in the name of a broker, dealer, commercial bank, trust company or other nominee and you wish to tender in the exchange offers, you should contact the registered holder promptly and instruct such person to tender on your behalf. If you wish to tender in the exchange offers on your own behalf, you must, prior to completing and executing the letter of transmittal and delivering your Original Notes, either arrange to have the Original Notes registered in your name or obtain a properly completed bond power from the registered holder. The transfer of registered ownership may take a considerable amount of time. See “The Exchange Offers—Procedures for Tendering.”

Withdrawal Rights

You may withdraw your tender of Original Notes at any time before the expiration date for the applicable exchange offer. See “The Exchange Offers—Withdrawal of Tenders.”

Regulatory Requirements

We do not believe that the receipt of any federal or state regulatory approval will be necessary in connection with the exchange offers, other than the notice of effectiveness under the Securities Act of the registration statement pursuant to which the exchange offers are made.

Accounting Treatment

We will not recognize any gain or loss for accounting purposes upon the completion of the exchange offers. The expenses of the exchange offers that we pay will increase our deferred financing costs in accordance with generally accepted accounting principles (“GAAP”). See “The Exchange Offers—Accounting Treatment.”

Federal Income Tax Consequences

The exchange of Original Notes for Exchange Notes pursuant to the exchange offers generally will not be a taxable event for U.S. federal income tax purposes. See “Material United States Federal Income Tax Considerations.”

Use of Proceeds

We will not receive any proceeds from the issuance of Exchange Notes in connection with the exchange offers. See “Use of Proceeds.”

Exchange Agent

U.S. Bank National Association (“U.S. Bank”) is serving as exchange agent in connection with the exchange offers. The address and telephone number of U.S. Bank are set forth under “The Exchange Offers—Exchange Agent.” U.S. Bank is also the trustee under the indentures governing the Original Notes and the Exchange Notes.

Summary of the Terms of the Notes

The summary below describes the principal terms of the Notes. Certain of the terms described below are subject to important limitations and exceptions.

such Exchange Notes, plus accrued and unpaid interest, if any, to, but excluding the repurchase date. See “Description of Notes—Certain covenants—Limitation on asset sales.”

Guarantees

The Exchange Notes are fully and unconditionally guaranteed on a senior unsecured basis by Olin.

In addition, in the future, the Exchange Notes will be fully and unconditionally guaranteed, jointly and severally, on a senior unsecured basis (collectively, the “guarantees” and each a “guarantee”) by any of Olin’s restricted subsidiaries (other than the Issuer) that guarantees the Senior Credit Facility or certain material capital markets debt issued by Olin, the Issuer or any subsidiary guarantor (if any). Under certain circumstances, the subsidiary guarantors may be automatically and unconditionally released from their guarantees without the consent of the holders of the Exchange Notes. See “Description of Notes—Certain covenants—Future guarantors.”

Ranking

The Exchange Notes are the Issuer’s senior unsecured obligations and:

•

rank senior in right of payment to all of the Issuer’s future subordinated indebtedness;

•

rank equally in right of payment with all of the Issuer’s existing and future senior indebtedness, including the Senior Credit Facility and the Sumitomo Term Facility;

•

are effectively subordinated to any of the Issuer’s existing and future secured debt, to the extent of the value of the assets securing such debt; and

•

are structurally subordinated to all of the existing and future liabilities (including trade payables) of the Issuer’s subsidiaries.

The guarantees are Olin’s senior unsecured obligations and:

•

rank senior in right of payment to all of Olin’s future subordinated indebtedness;

•

rank equally in right of payment with all of Olin’s existing and future senior indebtedness, including the Senior Credit Facility, the Sumitomo Term Facility and Olin’s other indebtedness described under the heading “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in Olin’s Annual Report on Form 10-K for the fiscal year ended December 31, 2015, and in Olin’s subsequent Quarterly Reports on Form 10-Q, each incorporated by reference herein;

•

are effectively subordinated to any of Olin’s existing and future secured debt, to the extent of the value of the assets securing such debt; and

•

are structurally subordinated to all of the existing and future liabilities (including trade payables) of each of Olin’s subsidiaries (other than the Issuer).

See “Risk Factors—Risks Related to the Notes and the Exchange Offers—The Exchange Notes are structurally subordinated to the indebtedness and other liabilities of the Issuer’s subsidiaries, and each guarantee is structurally subordinated to the indebtedness and other liabilities of Olin’s subsidiaries (other than the Issuer).”

As of March 31, 2016:

•

we had approximately $3,833.0 million of total indebtedness (including the Original Notes), of which $2,133.1 million would have ranked equally in right of payment with the Exchange Notes, including approximately $2,133.1 million of indebtedness under the Senior Credit Facility and the Sumitomo Term Facility (excluding an additional $15.1 million represented by letters of credit under the Senior Credit Facility);

•

of our total indebtedness, we had approximately $24.7 million of secured indebtedness to which the Exchange Notes and the guarantees would have been effectively subordinated; and

•

we had revolving commitments available to be borrowed under the Senior Credit Facility of $484.9 million (after giving effect to $15.1 million of outstanding letters of credit under the Senior Credit Facility).

Covenants

The indentures that govern the Exchange Notes contain covenants limiting the ability of Olin and its restricted subsidiaries, including the Issuer, to:

•

incur additional indebtedness and guarantee indebtedness;

•

pay dividends or make other distributions or repurchase or redeem Olin’s capital stock;

•

prepay, redeem or repurchase certain subordinated debt;

•

make loans and investments;

•

sell assets;

•

create certain liens;

•

enter into sale and leaseback transactions; and

•

consolidate or merge with, or sell, lease or convey all or substantially all of their respective properties or assets to, another person.

However, each of these covenants is subject to a number of significant exceptions. You should read “Description of Notes—Certain covenants” for a description of these covenants.

In addition, at such time as the Exchange Notes have received investment grade ratings from both Standard & Poor’s Ratings Services and Moody’s Investors Service, Inc. and no default or event of default exists under the applicable indenture that will govern the applicable series of Exchange Notes, certain of the covenants will be terminated. For more information, see “Description of Notes—Effectiveness of covenants.”

Absence of public market for the Notes

The Exchange Notes generally will be freely transferable but we cannot assure you that there will be a trading market for the Exchange Notes. We do not intend to apply for a listing of the Exchange Notes on any securities exchange or an automated dealer quotation system. Accordingly, a liquid market for the Exchange Notes may not develop. Those certain initial purchasers of the Original Notes (the “initial purchasers”) have previously advised us at the time the Original Notes were issued that they intended to make a market in the Notes. However, they are not obligated to do so, and any market making with respect to the Notes may be discontinued without notice.

Investing in the Notes involves substantial risks. You should carefully consider the risks described below and all of the information contained or incorporated by reference in this prospectus before deciding whether to participate in an exchange offer or invest in the Notes. In particular, we urge you to carefully consider the risk factors set forth in this “Risk Factors” section in addition to the risks described in Olin’s filings with the SEC, including Olin’s Annual Report on Form 10-K for the fiscal year ended December 31, 2015 incorporated by reference into this prospectus. You should also refer to the other information included or incorporated by reference in this prospectus, including our historical consolidated financial statements and the related notes.

Our indebtedness could adversely affect our financial condition and prevent us from fulfilling our obligations under the Notes.

As of March 31, 2016, we had $3,833.0 million of indebtedness outstanding. Outstanding indebtedness does not include amounts that could be borrowed under our $500.0 million senior revolving credit facility, under which $484.9 million was available for borrowing as of March 31, 2016 because we had issued $15.1 million of letters of credit. As of March 31, 2016, our indebtedness represented 61.8% of our total capitalization. At March 31, 2016, $205.1 million of our indebtedness was due within one year. Despite our level of indebtedness, we expect to continue to have the ability to borrow additional debt.

Our indebtedness could have important consequences, including but not limited to:

Our ability to generate sufficient cash flow from operations to make scheduled payments on our debt will depend on a range of economic, competitive and business factors, many of which are outside our control. There can be no assurance that our business will generate sufficient cash flow from operations to make these payments, including with respect to the Notes and the guarantees. If we are unable to meet our expenses and debt obligations, we may need to refinance all or a portion of our indebtedness before maturity, sell assets or issue additional equity. We may not be able to refinance any of our indebtedness, sell assets or issue additional equity on commercially reasonable terms or at all, which could cause us to default on our obligations and impair our liquidity. Our inability to generate sufficient cash flow to satisfy our debt obligations, or to refinance our debt obligations on commercially reasonable terms, would have a material adverse effect on our business, financial condition and results of operations, as well as on our ability to satisfy our debt obligations.

Restrictive covenants in the documents governing our indebtedness may limit our ability to undertake certain types of transactions.

The Senior Credit Facility, the Sumitomo Term Facility and the indentures that govern the Notes contain various restrictive covenants which may limit our financial flexibility in a number of ways. The Senior Credit

Facility and the Sumitomo Term Facility and the indentures that govern the Notes contain covenants that, among other things, restrict our ability, subject to specified exceptions, to incur additional debt, incur liens, sell or dispose of all or substantially all assets and merge with or consolidate into other companies. Additionally, if an event of default occurred under the Senior Credit Facility or the Sumitomo Term Facility, the applicable lenders could elect to declare all amounts outstanding thereunder, together with accrued interest, to be immediately due and payable. In such an event, we cannot assure you that we would have sufficient assets to pay amounts due on the Notes. As a result, you may receive less than the full amount you would otherwise be entitled to receive on the Notes.

Credit facilities—Weak industry conditions could affect our ability to comply with the financial maintenance covenants in our senior credit facility and certain tax-exempt bonds.

The Senior Credit Facility, the Sumitomo Term Facility and Olin’s Gulf Opportunity Zone Act of 2005 (Go Zone) and American Recovery and Reinvestment Act of 2009 (Recovery Zone) tax-exempt bonds include certain financial maintenance covenants requiring us to not exceed a maximum leverage ratio and to maintain a minimum coverage ratio.

Depending on the magnitude and duration of chlor alkali cyclical downturns, including deterioration in prices and volumes, there can be no assurance that we will continue to be in compliance with these ratios. If we failed to comply with either of these covenants in a future period and was not able to obtain waivers from the lenders thereunder, we would need to refinance the Senior Credit Facility, the Sumitomo Term Facility and the Go Zone and Recovery Zone bonds. However, there can be no assurance that such refinancing would be available to us on terms that would be acceptable to us or at all.

Our variable rate indebtedness subjects us to interest rate risk, which could cause our debt service obligations to increase significantly.

Borrowings under the Senior Credit Facility and the Sumitomo Term Facility are at variable rates of interest and expose us to interest rate risk. If interest rates were to increase, our debt service obligations on the variable rate indebtedness would increase even though the amount borrowed remained the same, and our net income and cash flows, including cash available for servicing our indebtedness, will correspondingly decrease. Assuming all loans are fully drawn, each quarter point change in interest rates would result in a $5 million change in annual interest expense on our indebtedness under the Senior Credit Facility and a $2 million change in annual interest expense on our indebtedness under the Sumitomo Term Facility. In the future, we may enter into interest rate swaps that involve the exchange of floating for fixed rate interest payments in order to reduce interest rate volatility. However, we may not maintain interest rate swaps with respect to all of our variable rate indebtedness, and any swaps we enter into may not fully mitigate our interest rate risk.

The Notes and each guarantee are effectively subordinated to any debt of the Issuer or Olin that is secured.

The Notes and each guarantee are unsecured obligations of the Issuer and Olin, respectively, and will be effectively subordinated to any future secured indebtedness of the Issuer or Olin with respect to the assets that secure that indebtedness. In addition, we may incur additional secured debt obligations in the future and the Notes and each guarantee will be effectively subordinated to that debt to the extent of the value of the assets securing that debt. The effect of this subordination is that if the Issuer or Olin is involved in a bankruptcy, liquidation, dissolution, reorganization or similar proceeding, or upon a default in payment on, or the acceleration of, any secured debt of the Issuer or Olin, the assets that secure such debt will be available to pay obligations on the Notes only after all such debt has been paid in full from the assets securing such debt. Holders of the Notes will participate in any remaining assets ratably with all of the other unsecured and unsubordinated creditors of the Issuer and Olin. The Issuer and Olin may not have sufficient assets remaining to pay amounts due on any or all of the Notes then outstanding. See “Description of Notes.”

The Notes are structurally subordinated to the indebtedness and other liabilities of the Issuer’s subsidiaries, and each guarantee is structurally subordinated to the indebtedness and other liabilities of Olin’s subsidiaries (other than the Issuer).

The Issuer is a holding company, and all of the assets of the Issuer consist of direct and indirect ownership interests in, and all of its business is conducted through, subsidiaries. Prior to the Transactions, Olin conducted most of its business at Olin Corporation and not through its subsidiaries. However, the Pioneer business, acquired in 2007, is operated through subsidiaries and the SunBelt business is also operated through subsidiaries. In 2011, Olin acquired the remaining 50% interest in the SunBelt joint venture, which is a chlor-alkali plant located within Olin’s McIntosh, Alabama facility. In 2007, Olin acquired Pioneer, a manufacturer of chlorine, caustic soda, bleach and hydrochloric acid. Pioneer consists of three chlor-alkali plants and two bleach manufacturing facility in North America. Olin’s subsidiaries (other than the Issuer) are separate legal entities that have no obligation to pay any amounts due under the Notes or the guarantees or to make any funds available therefor, whether by dividend, loan or other payment. As a consequence, the Issuer’s obligations under the Notes are structurally subordinated to existing and future indebtedness and other liabilities of subsidiaries of the Issuer and the obligations of Olin under the guarantees are structurally subordinated to existing and future indebtedness and other liabilities of Olin’s other subsidiaries. In addition, the right of the Issuer and Olin to participate in any distribution of assets of any of their respective subsidiaries upon their liquidation or reorganization or otherwise, and the ability of holders of the Notes to benefit indirectly from that kind of distribution, is subject to the prior claims of creditors of that subsidiary, except to the extent the Issuer or Olin is recognized as a creditor of that subsidiary. All obligations of the subsidiaries of Olin and the Issuer will have to be satisfied before any of the assets of such subsidiaries would be available for distribution, upon a liquidation or otherwise.

Olin’s Subsidiaries (other than the Issuer) represented approximately 62% of our net sales for the year ended December 31, 2015, and represented approximately 78% of our net sales for the three months ended March 31, 2016, respectively. As of March 31, 2016, Olin’s Subsidiaries (other than the Issuer) represented approximately 37% of our total assets and had 31% of total liabilities, including debt and trade payables but excluding intercompany liabilities.

Upon the occurrence of specific kinds of change of control, the holders of the Notes will have the right to require the Issuer to offer to repurchase all outstanding Notes at 101% of their principal amount, plus accrued and unpaid interest to the purchase date. Additionally, under the Senior Credit Facility and the Sumitomo Term Facility, a change of control (as defined therein) triggers a special prepayment right that permits the lenders to require a prepayment of borrowings under the relevant credit agreements and to terminate the commitments to lend thereunder. The source of funds for any purchase of the Notes and repayment of borrowings under the Senior Credit Facility or the Sumitomo Term Facility would be our available cash or cash generated from our subsidiaries’ operations or other sources, including borrowings, sales of assets or sales of equity. The Issuer may not be able to repurchase the Notes upon a change of control because the Issuer may not have sufficient financial resources to purchase all of the Notes that are tendered upon a change of control and repay our other indebtedness that will become due. If the Issuer fails to repurchase the Notes in that circumstance, the Issuer will be in default under the indentures that govern the Notes. The Issuer may require additional financing from third parties to fund any such purchases, and the Issuer may be unable to obtain financing on satisfactory terms or at all. Further, the Issuer’s ability to repurchase the Notes may be limited by law. In order to avoid the obligations to repurchase the Notes and special prepayment rights and potential breaches of the credit agreements governing the Senior Credit Facility and the Sumitomo Term Facility, we may have to avoid certain change of control transactions that would otherwise be beneficial to us.

In addition, certain important corporate events, such as leveraged recapitalizations, may not, under the indentures that govern the Notes, constitute a “change of control” that would require the Issuer to repurchase the Notes, even though those corporate events could increase the level of our indebtedness or otherwise adversely affect our capital structure, credit ratings or the value of the Notes. See “Description of Notes—Change of control.”

The exercise by the holders of notes of their right to require the Issuer to repurchase the Notes pursuant to a change of control offer could cause a default under the agreements governing our other indebtedness (including the indentures governing Olin’s existing notes), including future agreements, even if the change of control itself does not, due to the financial effect of such repurchases on us. In the event a change of control offer is required to be made at a time when the Issuer is prohibited from purchasing notes, we could attempt to refinance the borrowings that contain such prohibitions. If we do not obtain a consent or repay those borrowings, the Issuer will remain prohibited from purchasing notes. In that case, the Issuer’s failure to purchase tendered notes would constitute an event of default under the indentures that govern the Notes which could, in turn, constitute a default under our other indebtedness. Finally, the Issuer’s ability to pay cash to the holders of notes upon a repurchase may be limited by its then existing financial resources.

Holders of the Notes may not be able to determine when a change of control giving rise to their right to have the Notes repurchased has occurred following a sale of “substantially all” of our assets.

One of the circumstances under which a change of control may occur is upon the sale or disposition of “all or substantially all” of our assets. There is no precise established definition of the phrase “substantially all” under applicable law and the interpretation of that phrase will likely depend upon particular facts and circumstances. Accordingly, the ability of a holder of notes to require the Issuer to repurchase the Notes as a result of a sale of less than all our assets to another person may be uncertain.

Federal and state fraudulent transfer laws may permit a court to void the Notes and/or the guarantees, and if that occurs, you may not receive any payments on the Notes.

Federal and state fraudulent transfer and conveyance statutes may apply to the issuance of the Notes and the related guarantee. Under federal bankruptcy law and comparable provisions of state fraudulent transfer or conveyance laws, which may vary from state to state, the Notes or the guarantees thereof could be voided as a fraudulent transfer or conveyance if the Issuer or Olin, as applicable, (a) issued the Notes or the related guarantee, as applicable, with the intent of hindering, delaying or defrauding creditors or (b) received less than reasonably equivalent value or fair consideration in return for either issuing the Notes or incurring the guarantees and, in the case of (b) only, one of the following is also true at the time thereof:

As a general matter, value is given for a transfer or an obligation if, in exchange for the transfer or obligation, property is transferred or a valid antecedent debt is secured or satisfied. A court would likely find that the Parent Guarantor did not receive reasonably equivalent value or fair consideration for its guarantees to the extent Olin did not obtain a reasonably equivalent benefit directly or indirectly from the issuance of the Notes.

We cannot be certain as to the standards a court would use to determine whether or not the Issuer or Olin were insolvent at the relevant time or, regardless of the standard that a court uses, whether the Notes or the guarantees would be subordinated to the Issuer’s or Olin’s other debt. In general, however, a court would deem an entity insolvent if:

If a court were to find that the issuance of the Notes or the guarantees was a fraudulent transfer or conveyance, the court could void the payment obligations under the Notes or the guarantees, could subordinate the Notes or the guarantees to presently existing and future indebtedness of the Issuer or Olin or could require the holders of the Notes to repay any amounts received with respect to the guarantees. In the event of a finding that a fraudulent transfer or conveyance occurred, you may not receive any repayment on the Notes. Further, the avoidance of the Notes could result in an event of default with respect to our and our subsidiaries’ other debt that could result in acceleration of that debt.

Finally, as a court of equity, a bankruptcy court may subordinate the claims in respect of the Notes to other claims against the Issuer under the principle of equitable subordination if the court determines that (1) the holder of notes engaged in some type of inequitable conduct, (2) the inequitable conduct resulted in injury to our other creditors or conferred an unfair advantage upon the holders of notes and (3) equitable subordination is not inconsistent with the provisions of the bankruptcy code.

A lowering or withdrawal of the ratings assigned to our debt securities by rating agencies may increase our future borrowing costs and reduce our access to capital.

Any rating assigned to our debt could be lowered or withdrawn entirely by a rating agency if, in that rating agency’s judgment, future circumstances relating to the basis of the rating, such as adverse changes, so warrant. Consequently, real or anticipated changes in our credit ratings will generally affect the market value of the Notes. Credit ratings are not recommendations to purchase, hold or sell the Notes. Additionally, credit ratings may not reflect the potential effect of risks relating to the structure or marketing of the Notes.

Any future lowering of our ratings likely would make it more difficult or more expensive for us to obtain additional debt financing. If any credit rating assigned to the Notes is lowered or withdrawn for any reason, you may not be able to resell your notes without a substantial discount.

An active trading market may not develop for the Exchange Notes and you may be unable to sell the Exchange Notes at a price you deem sufficient or at all.

Each series of Exchange Notes is a new issue of securities for which there is currently no public trading market. We do not intend to list either series of the Exchange Notes on any securities exchange or to arrange for either series of Exchange Notes to be quoted on any automated interdealer quotation system. Accordingly, we cannot assure you that any trading market for the Exchange Notes will develop upon completion of the exchange offers or, if such a market does develop, that such market will be maintained or as to the liquidity of any market. If an active market does not develop or is not maintained, the market price and the liquidity of the Exchange Notes may be adversely affected. In addition, the liquidity of the trading market for the Exchange Notes, if it develops, and the market price quoted for the Exchange Notes, may be adversely affected by changes in prevailing interest rates and market conditions generally, as well as changes in our performance and negative changes in the ratings assigned to us or our debt securities.

If you fail to exchange your Original Notes, they will continue to be restricted securities and may become less liquid.

Original Notes that you do not tender or we do not accept will, following the exchange offers, continue to be restricted securities, and may not be offered or sold except pursuant to an exemption from, or in a transaction not subject to, the registration requirements of the Securities Act and applicable state securities laws. We will issue Exchange Notes in exchange for the Original Notes pursuant to the exchange offers only following the satisfaction of the procedures and conditions set forth in “The Exchange Offers—Procedures for Tendering.”

These procedures and conditions include timely receipt by the exchange agent of such Original Notes (or a confirmation of book-entry transfer) and of a properly completed and duly executed letter of transmittal (or an agent’s message from DTC, or compliance with the applicable procedures established by Euroclear or Clearstream).

Because we anticipate that most holders of Original Notes will elect to exchange their Original Notes, we expect that the liquidity of the market for any Original Notes remaining after the completion of the exchange offers will be substantially limited. Any Original Notes tendered and exchanged in the exchange offers will reduce the aggregate principal amount of the Original Notes outstanding. Following the exchange offers, if you do not tender your Original Notes, you generally will not have any further registration rights, and your Original Notes will continue to be subject to certain transfer restrictions. Accordingly, the liquidity of the market for the Original Notes could be adversely affected.

If you are a broker-dealer, your ability to transfer the Exchange Notes may be restricted.

A broker-dealer that acquired the Original Notes for its own account as a result of market-making activities or other trading activities must comply with the prospectus delivery requirements of the Securities Act in connection with any resale of the Exchange Notes. Our obligation to make this prospectus available to broker-dealers is limited. Consequently, we cannot guarantee that a proper prospectus will be available to broker-dealers wishing to resell their Exchange Notes.

The exchange offers are intended to satisfy our obligations under the Registration Rights Agreement entered into in connection with the issuance of the Original Notes. We will not receive any proceeds from the issuance of Exchange Notes in connection with the exchange offers. In consideration for issuing the Exchange Notes, we will receive the Original Notes from you in like principal amount. The Original Notes surrendered in exchange for the Exchange Notes will be retired and canceled and cannot be reissued. Accordingly, issuance of the Exchange Notes will not result in any change in our indebtedness other than to the extent that we incur any indebtedness in connection with the payment of expenses to be incurred in connection with the exchange offers, including the fees and expenses of the exchange agent and accounting and legal fees.

The following table sets forth information regarding the ratio of earnings to fixed charges for Olin and its consolidated subsidiaries (including the Issuer and its consolidated subsidiaries for the year ended December 31, 2015 and the three months ended March 31, 2016), for each of the periods shown.

In connection with the issuance and sale of the Original Notes, we entered into the Registration Rights Agreement with the initial purchasers, pursuant to which we agreed to (i) cause to be filed, and to use our reasonable best efforts to have declared effective, an exchange offer registration statement and (ii) consummate the exchange offers. The exchange offers are being made pursuant to the Registration Rights Agreement to satisfy our obligations thereunder.

We are making the exchange offers in reliance on the position of the SEC as described in previous no-action letters issued to third parties, including in Exxon Capital Holdings Corporation (April 13, 1988), Morgan Stanley & Co., Inc. (June 5, 1991), Shearman & Sterling (July 2, 1993) and similar no-action letters. However, we have not sought our own no-action letter. Based upon these interpretations by the SEC, we believe that a holder who exchanges Original Notes for Exchange Notes in the exchange offers generally may offer the Exchange Notes for resale, sell the Exchange Notes and otherwise transfer the Exchange Notes without further registration under the Securities Act and without delivery of a prospectus that satisfies the requirements of Section 10 of the Securities Act. The preceding sentence does not apply, however, to a holder who is our “affiliate” within the meaning of Rule 405 of the Securities Act. We also believe that a holder may offer, sell or transfer the Exchange Notes only if the holder acknowledges that the holder is acquiring the Exchange Notes in the ordinary course of its business and is not participating, does not intend to participate and has no arrangement or understanding with any person to participate in a distribution of the Exchange Notes. We have not entered into any arrangement or understanding with any person who will receive Exchange Notes in the exchange offers to distribute such Exchange Notes following completion of the exchange offers, and, to the best of our information and belief, we are not aware of any person that will participate in the exchange offers with a view to distribute the Exchange Notes. A holder who exchanges Original Notes for Exchange Notes in the exchange offers for the purpose of distributing such Exchange Notes cannot rely on the interpretations of the staff of the SEC in the aforementioned no-action letters, must comply with the registration and prospectus delivery requirements of the Securities Act in connection with any secondary resale of the Exchange Notes and must be identified as an underwriter in the prospectus.

Each broker-dealer that receives Exchange Notes for its own account in exchange for Original Notes, where such Original Notes were acquired by such broker-dealer as a result of market-making activities or other trading activities, must acknowledge that it will deliver a prospectus in connection with any resale of such Exchange Notes. This prospectus, as it may be amended or supplemented from time to time, may be used by a broker-dealer in connection with resales of Exchange Notes received in exchange for Original Notes where such Original Notes were acquired by such broker-dealer as a result of market-making activities or other trading activities. The letter of transmittal states that by acknowledging that it will deliver and by delivering a prospectus, a broker-dealer will not be considered to admit that it is an “underwriter” within the meaning of the Securities Act. We have agreed pursuant to the Registration Rights Agreement that, starting on the expiration date and ending 180 days after the expiration date, we will make this prospectus available to any broker-dealer for use in connection with any such resale. See “Plan of Distribution.”

Except as described above, this prospectus may not be used for an offer to resell, resale or other transfer of Exchange Notes.

then we will use our reasonable best efforts to file with the SEC and to have become effective a shelf registration statement relating to resales of the Original Notes and to keep such shelf registration statement effective until the date that the Original Notes cease to be “registrable securities” (as defined in the Registration Rights Agreement), or such shorter period that will terminate when all such Original Notes covered by the shelf registration statement have been sold pursuant to such shelf registration statement.

We will, in the event of such a shelf registration, provide to each participating holder of Original Notes copies of a prospectus, notify each participating holder of Original Notes when the shelf registration statement has become effective and take certain other actions to permit resales of the Original Notes. A holder of Original Notes covered by the shelf registration statement that sells Original Notes under the shelf registration statement generally will be required to make certain representations to us (as described in the Registration Rights Agreement), to be named as a selling security holder in the related prospectus and to deliver a prospectus to purchasers, will be subject to certain of the civil liability provisions under the Securities Act in connection with those sales and will be bound by the provisions of the Registration Rights Agreement that are applicable to such a holder of Original Notes (including certain indemnification obligations). Holders of such Notes will also be required to suspend their use of the prospectus included in the shelf registration statement under specified circumstances upon receipt of notice from us. Under applicable interpretations of the staff of the SEC, our affiliates will not be permitted to exchange their Original Notes for registered notes in the exchange offers.

then additional interest shall accrue on the principal amount of the Original Notes that are “registrable securities” at a rate of 0.25% per annum (which rate will be increased by an additional 0.25% per annum for each subsequent 90-day period that such additional interest continues to accrue, provided that the rate at which such additional interest accrues may in no event exceed 1.00% per annum) commencing on (a) October 6, 2016 or the 91st day following the request to file a shelf registration statement, as applicable, in the case of clause (i) above, or (b) the Trigger Date, in the case of clause (ii) above, until the exchange offers are completed or the shelf registration statement is declared effective or the prospectus again becomes usable, as applicable, or such Notes cease to be “registrable securities.”

This summary of certain provisions of the Registration Rights Agreement does not purport to be complete and is subject to, and is qualified in its entirety by, the complete provisions of the Registration Rights Agreement, which is incorporated by reference in this prospectus.

We are offering to exchange (i) the unregistered Original 2023 Notes for an equivalent amount of the Exchange 2023 Notes, which are registered under the Securities Act, and (ii) the unregistered Original 2025

Notes for an equivalent amount of the Exchange 2025 Notes, which are registered under the Securities Act. As of the date of this prospectus, $720,000,000 aggregate principal amount of Original 2023 Notes and $500,000,000 aggregate principal amount of Original 2025 Notes are outstanding.

Upon the terms and subject to the conditions of the exchange offers set forth in this prospectus and the accompanying letter of transmittal, we will accept any and all Original Notes validly tendered and not properly withdrawn prior to 11:59 p.m., New York City time, on the expiration date. Promptly after the expiration date (unless extended as described in this prospectus), we will deliver, or cause to be delivered to the trustee for cancellation, all “registrable securities” or portions thereof so accepted for exchange. We will issue, and cause the trustee to promptly authenticate and deliver to each holder who validly tendered Original Notes in the exchange offers, Exchange Notes for a like principal amount of outstanding Original Notes of the same series tendered and accepted in connection with the exchange offers. The Exchange Notes issued in connection with the exchange offers will be delivered promptly after the expiration date. Holders may tender some or all of their Original Notes in connection with the exchange offers, but only in minimum denominations of $2,000 in principal or integral multiples of $1,000 in excess thereof.

The terms of the Exchange Notes are substantially identical to the terms of the corresponding series of the Original Notes, except that the Exchange Notes are registered under the Securities Act, and the transfer restrictions, registration rights and payment of additional interest in case of non-registration applicable to the Original Notes do not apply to the Exchange Notes. The Exchange Notes of a given series will evidence the same debt as the Original Notes of such series and will be issued under the same indenture and be entitled to the same benefits under the indenture as the Original Notes being exchanged.

Except as described under “Description of Notes—Form,” Exchange Notes will be issued in the form of one or more global notes (the “Global Notes”) registered in the name of DTC or its nominee and each beneficial owner’s interest therein will be transferable in book-entry form through DTC. See “Description of Notes—Form.”

Holders of Original Notes do not have any appraisal or dissenters’ rights in connection with the exchange offers. We intend to conduct the exchange offers in accordance with the applicable requirements of Regulation 14E under the Exchange Act. Original Notes that are not tendered for exchange or are tendered but not accepted in connection with the exchange offers will remain outstanding, continue to accrue interest and be entitled to the benefits of the indenture under which they were issued, but certain registration and other rights under the Registration Rights Agreement will terminate and holders of the Original Notes will generally not be entitled to any registration rights under the Registration Rights Agreement. See “—Consequences of Failure to Properly Tender Original Notes in the Exchange Offers.”

We shall be considered to have accepted validly tendered Original Notes if and when we have given oral notice (to be followed by prompt written notice) or written notice to the exchange agent. The exchange agent will act as agent for the purposes of receiving the Exchange Notes from us.

If any tendered Original Notes are not accepted for exchange because of an invalid tender, the occurrence of certain other events described in this prospectus or otherwise, we will return the Original Notes, without expense, to the tendering holder promptly after the expiration date for the exchange offers.

Holders who tender Original Notes will not be required to pay brokerage commissions or fees or, subject to the instructions in the letter of transmittal, transfer taxes on exchange of Original Notes in connection with the exchange offers. We will pay all charges and expenses, other than certain applicable taxes described below, in connection with the exchange offers. See “—Fees and Expenses.”

As used in this prospectus, “expiration date” means 11:59 p.m., New York City time, on , 2016, unless we extend the expiration date for any exchange offer. In any event, the exchange offers will remain open

for at least 20 business days. We may extend the expiration date for any exchange offer in our sole discretion. If we so extend the expiration date for any exchange offer, the term “expiration date” for such exchange offer shall mean the latest date and time to which we extend such exchange offer.

We will give written notice of any delay, extension or termination to the exchange agent. In addition, we will give, as promptly as practicable, written notice regarding any delay in acceptance, extension or termination of any exchange offer to the registered holders of Original Notes. If we amend the terms of any exchange offer in a manner that we determine to constitute a material change (including if we so waive a material condition), we will promptly disclose the amendment in a manner reasonably calculated to inform the holders of Original Notes of the applicable series of the amendment, and extend such exchange offer if and as required by law.

If we determine to delay, extend, amend or terminate any exchange offer, we will timely issue a press release or other public announcement announcing such determination.

If we delay accepting any Original Notes or terminate any exchange offer, we promptly will return any Original Notes deposited pursuant to such exchange offer as required by Rule 14e-1(c) of the Exchange Act.

Interest on the Exchange 2023 Notes will be payable at 9.75% per annum. Interest on the Exchange 2025 Notes will be payable at 10.00% per annum. Interest on the Exchange Notes will be payable semi-annually in cash in arrears on April 15 and October 15 of each year. Interest on each series of Exchange Note will accrue from the last interest payment date on which interest was paid on the Original Note surrendered in exchange therefor. Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months.

Notwithstanding any other term of the exchange offers, we will not be required to accept for exchange, or to exchange any Exchange Notes for, any Original Notes and may terminate any or all of the exchange offers as provided in this prospectus before the acceptance of the Original Notes, if prior to the expiration date:

The conditions listed above are for our sole benefit and may be asserted by us regardless of the circumstances giving rise to any of these conditions. We may waive these conditions in whole or in part at any time and from time to time prior to the expiration of the exchange offers. The failure by us at any time to exercise any of the above rights shall not constitute a waiver of such right, and such right shall be considered an ongoing

right which we may assert at any time and from time to time prior to the expiration of the exchange offers. We are required to use our reasonable best efforts to obtain the withdrawal of any order suspending the effectiveness of the exchange offer registration statement.

If we determine that any of the events listed above has occurred, we may, subject to applicable law:

The tender by a holder of Original Notes, as set forth below, and our acceptance of the Original Notes will constitute a binding agreement between us and the holder in accordance with the terms and subject to the conditions set forth in this prospectus and in the accompanying letter of transmittal.

Unless the tender is being made in book-entry form, to tender in the exchange offers, a holder must:

Any financial institution that is a participant in DTC’s system, including Euroclear and Clearstream, may make book-entry delivery of the Original Notes by causing DTC to transfer the Original Notes into the exchange agent’s DTC account in accordance with DTC’s electronic Automated Tender Offer Program procedures for such transfer. The confirmation of such book-entry transfer will include an agent’s message stating that DTC has received an express acknowledgment from the participant in DTC tendering the Original Notes that the participant has received and agrees to be bound by the terms of the letter of transmittal and that we may enforce the terms of the letter of transmittal against such participant. A tender of Original Notes through a book-entry transfer into the exchange agent’s account will only be effective if an agent’s message or the letter of transmittal with any required signature guarantees and any other required documents are transmitted to and received or confirmed by the exchange agent at the address set forth below under the caption “—Exchange Agent,’’ prior to 11:59 p.m., New York City time, on the expiration date. Delivery of documents to DTC, Euroclear or Clearstream in accordance with their respective procedures does not constitute delivery to the exchange agent.

If you hold your position through Euroclear or Clearstream, the Original Notes so held must be tendered in compliance with the procedures established by Euroclear or Clearstream. You are encouraged to contact Euroclear or Clearstream directly to ascertain their procedure for tendering Original Notes. Neither we nor the trustee will have any responsibility for the performance by DTC, Euroclear or Clearstream or their participants or indirect participants of their obligations under the rules and procedures governing their operations.

The method of delivery of Original Notes and the letter of transmittal and all other required documents to the exchange agent is at the election and risk of the holders. Instead of delivery by mail, we recommend that holders use an overnight or hand delivery service. In all cases, holders should allow sufficient time to assure delivery to the exchange agent before the expiration date. No letter of transmittal or Original Notes should be sent to us. Holders may request their respective brokers, dealers, commercial banks, trust companies or nominees to effect the tenders for such holders.

Any beneficial owner whose Original Notes are registered in the name of a broker, dealer, commercial bank, trust company or other nominee and who wishes to tender should contact the registered holder promptly and instruct such registered holder to tender on behalf of the beneficial owner. If the beneficial owner wishes to tender on its own behalf, the beneficial owner must, prior to completing and executing the letter of transmittal and delivery of such owner’s Original Notes, either make appropriate arrangements to register ownership of the Original Notes in the owner’s name or obtain a properly completed bond power from the registered holder. The transfer of registered ownership may take considerable time.

Signature on a letter of transmittal or a notice of withdrawal, as the case may be, must be guaranteed by an eligible institution (as defined below) unless the Original Notes are being or were tendered:

In the event that signatures on a letter of transmittal or a notice of withdrawal, as the case may be, are required to be guaranteed, such guarantee must be by a financial institution (including most banks, savings and loan associations and brokerage houses) that is a participant in the Securities Transfer Agents Medallion Program, the New York Stock Exchange Medallion Signature Program or the Stock Exchanges Medallion Program (each such entity, an “eligible institution”).

If the letter of transmittal is signed by a person other than the registered holder(s) of any Original Notes, the certificate(s) representing such Original Notes must be endorsed by such registered holder(s) or accompanied by separate written instruments of transfer or endorsed in blank by such registered holder(s) in form satisfactory to us and duly executed by the registered holder, in either case signed exactly as such registered holder’s or holders’ name(s) appear(s) on the Original Notes.

If the letter of transmittal or any certificates of Original Notes or separate written instruments of transfer or exchange are signed or endorsed by trustees, executors, administrators, guardians, attorneys-in-fact, officers of corporations or other persons acting in a fiduciary or representative capacity, such persons should so indicate when signing and, unless waived by us, evidence satisfactory to us of their authority to so act must be submitted with the letter of transmittal.

We will determine all questions as to the validity, form, eligibility (including time of receipt) and acceptance and withdrawal of tendered Original Notes in our sole discretion, and our determination shall be final and binding on all parties. We reserve the absolute right to reject any and all Original Notes not properly tendered or any Original Notes whose acceptance by us would, in the opinion of our counsel, be unlawful. We also reserve the right to waive any defects, irregularities or conditions of tender as to any particular Original Notes either before or after the expiration date. Our interpretation of the terms and conditions of the exchange offers (including the instructions in the letter of transmittal) will be final and binding on all parties. Unless waived, any defects or irregularities in connection with tenders of Original Notes must be cured within a time period we will determine. Although we intend to request the exchange agent to notify holders of defects or irregularities relating to tenders of Original Notes, neither we, the exchange agent nor any other person will have any duty or incur any liability for failure to give such notification. Tenders of Original Notes will not be considered to have been made until such defects or irregularities have been cured or waived. Any Original Notes

received by the exchange agent that are not properly tendered and as to which the defects or irregularities have not been cured or waived will be returned by the exchange agent to the tendering holders, unless otherwise provided in the letter of transmittal, promptly following the expiration date.

In addition, we reserve the right, as set forth above under the caption “—Conditions to the Exchange Offers,” to terminate any or all of the exchange offers. By tendering, each holder represents and acknowledges:

Except as otherwise provided herein, tenders of Original Notes may be withdrawn at any time prior to 11:59 p.m., New York City time, on the expiration date.

To withdraw a tender of Original Notes in connection with the exchange offers, a written notice of withdrawal must be received by the exchange agent at its address set forth herein prior to 11:59 p.m., New York City time, on the expiration date. Any such notice of withdrawal must:

If Original Notes have been tendered pursuant to the procedure for book-entry transfer, any notice of withdrawal must specify the name and number of the account at DTC to be credited with the withdrawn Original Notes or otherwise comply with DTC’s procedures or the procedures of Euroclear or Clearstream, as applicable.

We will determine in our sole discretion all questions as to the validity, form and eligibility (including time of receipt) of such withdrawal notices, and our determination shall be final and binding on all parties. Any Original Notes so withdrawn will be considered not to have been validly tendered for purposes of the exchange offers, and no Exchange Notes will be issued for properly withdrawn Original Notes unless the Original Notes so withdrawn are validly re-tendered. Any Original Notes which have been tendered but which are not accepted for exchange or which are withdrawn will be returned to the holder without cost to such holder promptly after withdrawal, rejection of tender or termination of the exchange offers. Properly withdrawn Original Notes may be re-tendered by following one of the procedures described above under “—Procedures for Tendering” at any time prior to the expiration date.

We have appointed U.S. Bank National Association as exchange agent in connection with the exchange offers. Questions and requests for assistance, as well as requests for additional copies of this prospectus or of the letter of transmittal, should be directed to the exchange agent at its offices at 60 Livingston Avenue, St. Paul, Minnesota 55107, Attention: Specialized Finance. The exchange agent’s telephone number is (800) 934-6802 and its facsimile number is (651) 466-7372, Attention: Specialized Finance.

DELIVERY OF THE LETTER OF TRANSMITTAL TO AN ADDRESS OTHER THAN AS SET FORTH ABOVE OR TRANSMISSION OF SUCH LETTER OF TRANSMITTAL VIA FACSIMILE OTHER THAN AS SET FORTH ABOVE DOES NOT CONSTITUTE A VALID DELIVERY OF THE LETTER OF TRANSMITTAL.

We have not retained any dealer manager in connection with the exchange offers and we will not make any payment to brokers, dealers or others soliciting acceptances of the exchange offers. We will pay certain other expenses to be incurred in connection with the exchange offers, including the fees and expenses of the exchange agent and certain accountant and legal fees.

Holders who tender their Original Notes for exchange will not be obligated to pay any transfer taxes. If, however, Exchange Notes are to be delivered to, or issued in the name of, any person other than the registered holder of the Original Notes tendered, tendered Original Notes are registered in the name of any person other than the person signing the letter of transmittal, or a transfer tax is imposed for any reason other than the exchange of Original Notes in connection with the exchange offers, then the tendering holder must pay the amount of any transfer taxes due, whether imposed on the registered holder or any other persons. If the tendering holder does not submit satisfactory evidence of payment of these taxes or exemption therefrom with the letter of transmittal, the amount of these transfer taxes will be billed directly to the tendering holder.

The Exchange Notes will be recorded at the same carrying value as the Original Notes as reflected in our accounting records on the date of the exchange. Accordingly, we will not recognize any gain or loss for accounting purposes upon the completion of the exchange offers. The expenses of the exchange offers that we pay will increase our deferred financing costs in accordance with GAAP.

Consequences of Failure to Properly Tender Original Notes in the Exchange Offers

Issuance of the Exchange Notes in exchange for the Original Notes under the exchange offers will be made only after timely receipt by the exchange agent of a properly completed and duly executed letter of transmittal (or an agent’s message from DTC or similar notification pursuant to the procedures of Euroclear or Clearstream) and the certificate(s) representing such Original Notes (or confirmation of book-entry transfer), and all other required

documents. Therefore, holders of the Original Notes desiring to tender such Original Notes in exchange for Exchange Notes should allow sufficient time to ensure timely delivery of such documents. We are under no duty to give notification of defects or irregularities of tenders of Original Notes for exchange or waive any such defects or irregularities. Original Notes that are not tendered or that are tendered but not accepted by us will, following completion of the exchange offers, continue to be subject to the existing restrictions upon transfer thereof under the Securities Act, and, upon completion of the exchange offers, certain registration rights under the Registration Rights Agreement will terminate.

In the event the exchange offers are completed, we generally will not be required to register the remaining Original Notes, subject to limited exceptions. Original Notes that remain outstanding will continue to be subject to the following restrictions on transfer:

We do not currently anticipate that we will register the remaining Original Notes under the Securities Act. To the extent that Original Notes are tendered and accepted in connection with the exchange offers, any trading market for remaining Original Notes could be adversely affected. See “Risk Factors—Risks Related to the Notes and the Exchange Offers—If you fail to exchange your Original Notes, they will continue to be restricted securities and may become less liquid.”

Neither Olin’s nor Blue Cube’s board of directors makes any recommendation to holders of Original Notes as to whether to tender or refrain from tendering all or any portion of their Original Notes pursuant to the exchange offers. Moreover, no one has been authorized to make any such recommendation. Holders of Original Notes must make their own decision whether to tender pursuant to the exchange offers and, if so, the aggregate amount of Original Notes to tender, after reading this prospectus and the letter of transmittal and consulting with their advisors, if any, based on their own financial position and requirements.

The definitions of certain capitalized terms as such terms are used in this section are set forth below under “—Certain definitions.” When used in this section, (i) the term “Issuer” refers to Blue Cube Spinco Inc., a Delaware corporation, and not to any of its Subsidiaries and (ii) the term “Parent” refers to Olin Corporation, a Virginia corporation, and not to any of its Subsidiaries.

The Exchange 2023 Notes will be issued under an indenture dated October 5, 2015, among the Issuer and U.S. Bank National Association, as trustee (the “Trustee”), as supplemented by a first supplemental indenture among the Parent, the Issuer and the Trustee (the “2023 Indenture”). The Exchange 2025 Notes will be issued under an indenture dated October 5, 2015, among the Issuer and the Trustee, as supplemented by a first supplemental indenture among the Parent, the Issuer and the Trustee (the “2025 Indenture”).

The 2023 Indenture and the 2025 Indenture are collectively referred to herein as the “Indentures.” Unless otherwise expressly stated or the context otherwise requires, the Original Notes and the Exchange Notes are referred to in this “Description of Notes” together as the “Notes.” We refer to the Original 2023 Notes and the Exchange 2023 Notes together as the “2023 Notes” and the Original 2025 Notes and the Exchange 2025 Notes together as the “2025 Notes”. The terms of each series of the Notes include those expressly set forth in the Indentures and those made part of the Indentures by reference to the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”). The Original Notes were issued in a private debt offering pursuant to exemptions from the registration requirements of the Securities Act and are subject to certain transfer restrictions. See “Transfer restrictions.”

This “Description of Notes” section is intended to be an overview of the material provisions of each series of Notes, the guarantees and the Indentures. Since this “Description of Notes” section is only a summary, you should refer to the Indentures for a complete description of the obligations of the Issuer, the Parent and your rights. You may request copies of the Notes and the Indentures at the address set forth under the heading “Where You Can Find More Information; Incorporation By Reference.”

The initial offering of the Original 2023 Notes was for an aggregate principal amount of $720,000,000 and the initial offering of the Original 2025 Notes was for an aggregate principal amount of $500,000,000. The Issuer may issue an unlimited principal amount of additional notes of each series having identical terms and conditions as the Notes of such series, other than the date of issuance and, under certain circumstances, the first interest payment date and the date from which interest thereon will begin to accrue (any such additional notes with respect to a series of Notes, the “Additional Notes” of such series); provided that if any Additional Notes of a series are not fungible with the Notes of such series issued in this offering for U.S. federal income tax purposes, such Additional Notes will have a separate CUSIP number and ISIN from the Notes of such series issued in this offering, as applicable. The Issuer is only permitted to issue such Additional Notes in compliance with the covenant described under the subheading “—Certain covenants—Limitation on debt.” Any Additional Notes of a series will be part of the same issue as the Notes of such series and will vote on all matters with the Holders of the Notes of such series. The Notes of a series (and any Additional Notes of such series) will constitute a series of debt securities under the Indenture for such series.

Interest on the 2023 Notes is payable at 9.75% per annum. Interest on the 2025 Notes is payable at 10.00% per annum. Interest on the Notes is payable semi-annually in cash in arrears on April 15 and October 15. The Issuer will make each interest payment to the Holders of record as of the close of business on the immediately preceding April 1 and October 1. Interest on the Exchange Notes will accrue from the most recent date to which interest has been paid on the corresponding series of Original Notes or, if no interest has been paid on such Original Notes, from and including October 1, 2015. Interest is computed on the basis of a 360-day year comprised of twelve 30-day months.

Principal of and premium, if any, and interest on the Notes will be payable, and the Notes will be exchangeable and transferable, at the office or agency of the Issuer maintained for such purposes, which, initially, will be the corporate trust office designated in each Indenture. If a Holder has given wire instructions to the Issuer or the paying agent, the paying agent will distribute the payments received of principal, and, if applicable, of interest and premium, if any, on that Holder’s Notes in accordance with those instructions; provided, however, that payment of interest may be made at the option of the Issuer by check mailed to the Person entitled thereto as shown on the security register, subject to the customary procedures of any depository for the Notes.

The Exchange Notes will be issued only in fully registered form without coupons, in denominations of $2,000 and any integral multiple of $1,000 in excess thereof. No service charge will be made for any registration of transfer, exchange or redemption of Notes, except in certain circumstances for any tax or other governmental charge that may be imposed in connection therewith.

The Notes are general unsecured senior obligations of the Issuer. As a result, the Notes:

The Notes are guaranteed on a full and unconditional senior unsecured basis by the Parent. As a result, each Guarantee:

As of March 31, 2016, the Parent and its subsidiaries had approximately $3,833.0 million of total indebtedness (including the Notes). In addition, as of March 31, 2016, the Parent and its subsidiaries had revolving commitments available to be borrowed under the Credit Agreement of $484.9 million (after giving effect to $15.1 million of outstanding letters of credit under the Credit Agreement).

None of the Parent’s Subsidiaries guarantee the Notes as of the date hereof. In the event of a bankruptcy, liquidation or reorganization of any of the Parent’s Subsidiaries (other than the Issuer), these Subsidiaries must pay the holders of their debts and their trade creditors in full before they will be permitted to distribute any of their assets to the Issuer or the Parent.

conducted most of its business at Olin Corporation and not through its subsidiaries. However, the Pioneer business, acquired in 2007, is operated through subsidiaries and the SunBelt business is also operated through subsidiaries. In 2011, Olin acquired the remaining 50% interest in the SunBelt joint venture, which is a chlor-alkali plant located within Olin’s McIntosh, Alabama facility. In 2007, Olin acquired Pioneer, a manufacturer of chlorine, caustic soda, bleach and hydrochloric acid. Pioneer consists of three chlor-alkali plants and two bleach manufacturing facilities in North America. The Parent’s subsidiaries (other than the Issuer) are separate legal entities that have no obligation to pay any amounts due under the Notes or the guarantees or to make any funds available therefor, whether by dividend, loan or other payment. As a consequence, the Issuer’s obligations under the Notes will be structurally subordinated to existing and future indebtedness and other liabilities of subsidiaries of the Issuer and the obligations of the Parent under the guarantees are structurally subordinated to existing and future indebtedness and other liabilities of the Parent’s other subsidiaries. In addition, the right of the Issuer and the Parent to participate in any distribution of assets of any of their respective subsidiaries upon their liquidation or reorganization or otherwise, and the ability of holders of the Notes to benefit indirectly from that kind of distribution, is subject to the prior claims of creditors of that subsidiary, except to the extent the Issuer or the Parent is recognized as a creditor of that subsidiary. All obligations of the subsidiaries of the Parent and the Issuer will have to be satisfied before any of the assets of such subsidiaries would be available for distribution, upon a liquidation or otherwise.

The Parent’s Subsidiaries (other than the Issuer) represented approximately 62% of our net sales for the year ended December 31, 2015, and represented approximately 78% of our net sales for the three months ended March 31, 2016, respectively. As of March 31, 2016, the Parent’s Subsidiaries (other than the Issuer) represented approximately 37% of our total assets and had 31% of total liabilities, including debt and trade payables but excluding intercompany liabilities.

As of the date hereof, all of the Parent’s Subsidiaries are “Restricted Subsidiaries.” However, under the circumstances described below under the definition of “Unrestricted Subsidiary,” any of the Parent’s Subsidiaries may be designated as “Unrestricted Subsidiaries.” Unrestricted Subsidiaries are not subject to the restrictive covenants in the Indentures.

There are no mandatory sinking fund payment obligations with respect to the Notes.

On and after October 15, 2020, the Issuer may, on any one or more occasions, redeem the Notes of any series, in whole or in part, upon not less than 30 nor more than 60 days’ notice mailed or otherwise delivered to each Holder of the Notes of such series in accordance with the applicable procedures of DTC, at the redemption prices (expressed as a percentage of principal amount of the Notes of such series to be redeemed) set forth below, plus accrued and unpaid interest on the Notes of such series, if any, to the applicable date of redemption, if redeemed during the 12-month period beginning on October 15 of each of the years indicated below:

Unless the Issuer defaults in payment of the redemption price, on and after the redemption date, interest will cease to accrue on the Notes or portions of the Notes called for redemption and those Notes will cease to be outstanding.

If an optional redemption date is on or after an interest payment record date and on or before the related interest payment date, the accrued and unpaid interest on the Notes being redeemed, if any, will be paid to the Person in whose name such Note is registered at the close of business, on such record date, and no additional interest will be payable to the Holder of such Note on the redemption date.

In the case of any partial redemption, selection of the Notes of a series for redemption will be made by the Trustee in compliance with the requirements of the principal national securities exchange, if any, on which the Notes of such series are listed or, if such Notes are not listed, then on a pro rata basis, by lot in accordance with the applicable procedures of DTC or by such other method as the Trustee in its sole discretion deems to be fair and appropriate, although no Note of $2,000 in principal amount or less will be redeemed in part. If any Note is to be redeemed in part only, the notice of redemption relating to such Note will state the portion of the principal amount thereof to be redeemed. A new Note in principal amount equal to the unredeemed portion thereof will be issued in the name of the Holder thereof upon cancellation of the original Note.

Any redemption notice may, at the Issuer’s discretion, be subject to one or more conditions precedent, including completion of any transaction.

The Issuer may at any time, and from time to time, acquire Notes by means other than a redemption, whether by tender offer, open market purchases, negotiated transactions or otherwise, in accordance with applicable securities laws.

If a Change of Control occurs, unless the Issuer has exercised its right to redeem the Notes of a series as described above under “—Optional redemption,” the Issuer will make an offer to each Holder of a series to repurchase all or any part (in multiples of $1,000 principal amount) of that Holder’s Notes at a repurchase price in cash equal to 101% of the aggregate principal amount of Notes repurchased plus any accrued and unpaid interest on the Notes repurchased to the date of purchase.

Within 30 days following any Change of Control, unless the Issuer has exercised its right to redeem the Notes of a series as described above under “—Optional redemption,” or, at the Issuer’s option, prior to any Change of Control, but after the public announcement of the Change of Control, the Issuer will mail a notice to each Holder of a series describing the transaction or transactions that constitute or may constitute the Change of Control and offering to repurchase Notes of such series on the payment date specified in the notice, which date will be no earlier than 30 days and no later than 60 days from the date such notice is mailed. The notice shall, if mailed prior to the date of consummation of the Change of Control, state that the offer to purchase is conditioned on the Change of Control occurring on or prior to the payment date specified in the notice.

repurchase of any Notes as a result of a Change of Control. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control provisions of the Notes, the Issuer will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the Change of Control provisions of the Notes by virtue of such conflict.

On the Change of Control payment date with respect to a series of Notes, the Issuer will, to the extent lawful:

(1) accept for payment all Notes or portions of Notes (in integral multiples of $1,000) of such series properly tendered pursuant to the Issuer’s offer; provided that if, following repurchase of a portion of a Note, the remaining principal amount of such Note outstanding immediately after such repurchase would be less than $2,000, then the portion of such Note so repurchased shall be reduced so that the remaining principal amount of such Note outstanding immediately after such repurchase is $2,000;

(2) deposit with the paying agent an amount equal to the aggregate purchase price in respect of all Notes or portions of Notes of such series properly tendered; and

(3) deliver or cause to be delivered to the Trustee the Notes of such series properly accepted, together with an Officers’ Certificate stating the aggregate principal amount of Notes of such series being purchased by the Issuer.

The paying agent will promptly mail (or otherwise deliver in accordance with the applicable procedures of DTC) to each Holder of Notes of such series properly tendered the purchase price for such Notes, and the Trustee will promptly authenticate and mail (or otherwise deliver in accordance with the applicable procedures of DTC) (or cause to be transferred by book-entry) to each Holder a new Note of such series equal in principal amount to any unpurchased portion of any Notes surrendered; provided that each new Note will be in a principal amount of $2,000 or an integral multiple of $1,000.

If the Change of Control payment date with respect to a series of Notes is on or after an interest payment record date and on or before the related interest payment date, any accrued and unpaid interest to the Change of Control payment date will be paid on the Change of Control payment date to the Person in whose name such Note is registered at the close of business on such record date.

The Issuer will not be required to make an offer to repurchase the Notes of any series upon a Change of Control if a third party makes an offer in the manner, at the times and otherwise in compliance with the requirements for an offer made by the Issuer and such third party purchases all Notes of such series properly tendered and not withdrawn under its offer.

The definition of Change of Control includes a phrase relating to the direct or indirect sale, lease, transfer, conveyance or other disposition of “all or substantially all” of the property and assets of the Parent and its Subsidiaries, taken as a whole. Although there is a limited body of case law interpreting the phrase “substantially all,” there is no precise established definition of the phrase under applicable law. Accordingly, the ability of a Holder to require the Issuer to repurchase Notes as a result of a sale, lease, transfer, conveyance or other disposition of less than all of the properties and assets of the Parent and its Subsidiaries, taken as a whole, to another person (as that term is used in Section 13(d)(3) of the Exchange Act) may be uncertain.

The Issuer’s ability to pay cash to the Holders upon a Change of Control may be limited by the Issuer’s and the Parent’s then existing financial resources. Further, future agreements of the Issuer and the Parent may contain prohibitions of certain events, including events that would constitute a Change of Control. If the exercise by the Holders of their right to require the Issuer to repurchase the Notes upon a Change of Control occurred at the same time as a change of control event under one or more of the Issuer’s or the Parent’s other debt agreements, the Issuer’s ability to pay cash to the Holders upon a repurchase may be further limited by the Issuer’s and the Parent’s then existing financial resources. See “Risk Factors—Risks Related to the Notes and the Exchange Offers—We may not be able to repurchase the notes upon a change of control.”

Even if sufficient funds were otherwise available, the terms of future indebtedness may prohibit the Issuer’s and the Parent’s prepayment or repurchase of the Notes before their scheduled maturity. Consequently, if the Issuer or the Parent is not able to prepay obligations under any such other indebtedness or obtain requisite consents, the Issuer and the Parent will be unable to fulfill its repurchase obligations, resulting in a default under the applicable Indenture. A default under the Indentures may result in a cross-default under the Credit Agreement or other indebtedness. Holders may not be entitled to require the Issuer to purchase their Notes in certain circumstances involving a significant change in the composition of the Board of Directors of the Parent, including in connection with a proxy contest where the Board of Directors of the Parent approves them as Continuing Directors, even if the Board of Directors of the Parent initially opposed the directors.

The provisions of the Indentures will not afford Holders protection in the event of a highly leveraged transaction, reorganization, restructuring, merger or similar transaction affecting the Parent or the Issuer that may adversely affect Holders, if such transaction is not the type of transaction included within the definition of Change of Control. A transaction involving the management of the Parent or its affiliates, or a transaction involving a recapitalization of the Parent or the Issuer, will result in a Change of Control only if it is the type of transaction specified in such definition. Certain provisions under the Indentures relative to the Issuer’s obligation to make an offer to repurchase the Notes of a series as a result of a Change of Control may be amended or modified with the written consent of the Holders of a majority in aggregate principal amount of outstanding Notes of such series. See “—Amendment, supplement and waiver.”

In addition, an offer to repurchase may be made in advance of a Change of Control, conditional upon such Change of Control, if a definitive agreement is in place for a Change of Control at the time of launching the offer to repurchase.

Set forth below are summaries of certain covenants that are contained in the Indenture for each series of Notes.

The Parent will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, make any Restricted Payment unless, at the time of and after giving effect to the proposed Restricted Payment:

(a) no Default shall have occurred and be continuing or will occur as a consequence thereof;

(b) after giving effect to such Restricted Payment on a pro forma basis, the Parent would be permitted to incur at least $1.00 of Coverage Debt under the “Limitation on debt” covenant; and

(c) after giving effect to such Restricted Payment on a pro forma basis, the aggregate amount of all Restricted Payments made after the Issue Date (excluding (x) Restricted Payments permitted by clauses (ii) through (viii) of the next succeeding paragraph and (y) Restricted Payments permitted by clause (ix) of the next succeeding paragraph to the extent that the amount available for Restricted Payments under this clause (c) would be reduced to less than zero as a result of payments made under such clause (ix)), shall not exceed the sum (without duplication) of

(1) 50% of the Consolidated Net Income (or, if Consolidated Net Income shall be a deficit, minus 100% of such deficit) of the Parent accrued on a cumulative basis during the period (taken as one accounting period) from the beginning of the fiscal quarter during which the Issue Date occurs and ending on the last day of the fiscal quarter immediately preceding the date of such proposed Restricted Payment, plus

(2) 100% of the aggregate net proceeds (including the fair market value of property other than cash as determined by the Parent in good faith) received by the Parent subsequent to the initial issuance of the Notes either (i) as a contribution to its common equity capital or (ii) from the issuance and sale (other than to a Subsidiary) of its Qualified Capital Interests, including Qualified Capital Interests issued upon the conversion of Debt, Redeemable Capital Interests or preferred stock of the Parent, and from the

(3) to the extent that any Investment (other than Permitted Investments or Investments in Unrestricted Subsidiaries) that was made on or after the Issue Date is sold for cash or otherwise disposed of, liquidated, redeemed, repurchased or repaid for cash or other assets, or to the extent that the Parent otherwise realizes any proceeds on the sale of such Investment or proceeds representing the return of capital on such Investment, the lesser of (i) the initial amount of such Investment, or (ii) to the extent not otherwise included in the calculation of Consolidated Net Income of the Parent for such period, the net cash return of capital or net fair market value of return of capital as determined by the Parent in good faith with respect to such Investment, less the cost of any such disposition or liquidation, plus

(4) to the extent that any Unrestricted Subsidiary of the Parent designated as such on or after the Issue Date is redesignated as a Restricted Subsidiary, the lesser of (i) the fair market value of the Parent’s Investment in such Subsidiary as of the date of such redesignation as determined by the Parent in good faith or (ii) such fair market value as of the date on which such Subsidiary was originally designated as an Unrestricted Subsidiary, plus

Notwithstanding whether the foregoing provisions would prohibit the Parent and its Restricted Subsidiaries from making a Restricted Payment, the Parent and its Restricted Subsidiaries may make the following Restricted Payments:

(i) the payment of any dividend on Capital Stock in the Parent or a Restricted Subsidiary within 60 days after declaration thereof if at the declaration date such payment was permitted by the provisions of this covenant;

(ii) the purchase, repurchase, redemption, defeasance or other acquisition or retirement of any Qualified Capital Interests of the Parent by conversion into, or by or in exchange for, Qualified Capital Interests, or out of net cash proceeds of the substantially concurrent sale (other than to a Restricted Subsidiary of the Parent) of other Qualified Capital Interests of the Parent;

(iii) the redemption, defeasance, repurchase or acquisition or retirement for value of any Debt of the Parent or a Subsidiary Guarantor that is subordinate in right of payment to the Notes or the applicable Guarantee out of the net cash proceeds of a substantially concurrent issue and sale (other than to a Subsidiary of the Parent) of (x) new subordinated Debt of the Parent or such Subsidiary Guarantor, as the case may be, incurred in accordance with the applicable Indenture or (y) of Qualified Capital Interests of the Parent;

(iv) the purchase, redemption, retirement or other acquisition for value of Capital Stock of the Parent held by employees or former employees of the Parent or any Restricted Subsidiary (or their estates or beneficiaries under their estates) upon death, disability, retirement or termination of employment or alteration of employment status or pursuant to the terms of any agreement under which such Capital Stock was issued; provided, however, that the aggregate cash consideration paid for such purchase, redemption, retirement or other acquisition of such Capital Stock does not exceed $5.0 million in any calendar year; provided further, however, that any unused amounts in any calendar year may be carried forward to one or more future periods subject to a maximum aggregate amount of repurchases made pursuant to this clause (iv) not to exceed $10.0 million in any calendar year; provided, however, that such amount in any calendar year may be increased by an amount not to exceed (A) the cash proceeds received by the Parent or any of its Restricted Subsidiaries from the sale of Qualified Capital Interests of the Parent to employees of the Parent and its Restricted Subsidiaries that occurs after the Issue Date; provided, however, that the amount of such cash proceeds utilized for any such repurchase, retirement, other acquisition or dividend will not increase the amount available for Restricted Payments under clause (c) of the first paragraph of this covenant; plus (B) the cash proceeds of key man life insurance policies received by the Parent and its Restricted

Subsidiaries after the Issue Date (provided, however, that the Parent may elect to apply all or any portion of the aggregate increase contemplated by the proviso of this clause (iv) in any calendar year);

(v) repurchase of Capital Stock deemed to occur upon the exercise of stock options, warrants or other convertible or exchangeable securities;

(vi) cash payment, in lieu of issuance of fractional shares in connection with the exercise of warrants, options or other securities convertible into or exchangeable for the Capital Stock of the Parent or a Restricted Subsidiary;

(vii) the declaration and payment of dividends to holders of any class or series of Redeemable Capital Interests of the Parent or any Restricted Subsidiary issued or incurred in compliance with the covenant described below under “—Limitation on debt”;

(viii) upon the occurrence of a Change of Control or an Asset Sale, the defeasance, redemption, repurchase or other acquisition of any subordinated Debt pursuant to provisions substantially similar to those described under “—Change of control” and “—Limitation on asset sales” at a purchase price not greater than 101% of the principal amount thereof (in the case of a Change of Control) or at a percentage of the principal amount thereof not higher than the principal amount applicable to the Notes (in the case of an Asset Sale), plus any accrued and unpaid interest thereon; provided, however, that prior to or contemporaneously with such defeasance, redemption, repurchase or other acquisition, the Issuer has made an Offer to Purchase with respect to the applicable Notes and has repurchased all Notes validly tendered for payment and not withdrawn in connection therewith;

(ix) to the extent no Default in any payment in respect of principal or interest under the Notes or Event of Default has occurred and is continuing or will occur as a consequence thereof, the payment of regular cash quarterly dividends on the Parent’s common stock; provided, however, that in no event shall the amount of dividends paid in any calendar year under this clause (ix) exceed $200.0 million;

(xi) to the extent no Default in any payment in respect of principal or interest under the Notes or an Event of Default has occurred and is continuing or will occur as a consequence thereof, other Restricted Payments not in excess of $50.0 million in the aggregate;

(xii) to the extent no Default in any payment in respect of principal or interest under the Notes or an Event of Default has occurred and is continuing or will occur as a consequence thereof, any Restricted Payment so long as on the date of such Restricted Payment, after giving pro forma effect thereto and to any related transactions as if the same had occurred at the beginning of the Parent’s most recent four consecutive fiscal quarters for which internal financial statements of the Parent are available, the Consolidated Debt Ratio would not exceed 2.50 to 1.00; and

If any Person in which an Investment is made, which Investment constitutes a Restricted Payment when made, thereafter becomes a Restricted Subsidiary in accordance with the applicable Indenture, all such Investments previously made in such Person shall no longer be counted as Restricted Payments for purposes of calculating the aggregate amount of Restricted Payments pursuant to clause (c) of the first paragraph under this “Limitation on restricted payments” covenant, in each case to the extent such Investments would otherwise be so counted.

For purposes of this covenant, if a particular Restricted Payment involves a non-cash payment, including a distribution of assets, then such Restricted Payment shall be deemed to be an amount equal to the cash portion of such Restricted Payment, if any, plus an amount equal to the fair market value of the non-cash portion of such Restricted Payment as determined by the Parent in good faith.

The Parent will not, and will not permit any of its Restricted Subsidiaries to, incur any Debt (including Acquired Debt); provided, however, that the Parent, the Issuer and any Restricted Subsidiary may incur Debt (including Acquired Debt) if, immediately after giving effect to the incurrence of such Debt and the receipt and application of the proceeds therefrom, (a) the Consolidated Fixed Charge Coverage Ratio of the Parent and its Restricted Subsidiaries would be greater than 2.00 to 1.00 and (b) no Default shall have occurred and be continuing at the time or as a consequence of the incurrence of such Debt (any Debt incurred pursuant to this provision being herein referred to as “Coverage Debt”); provided, however, that the amount of Debt (other than Acquired Debt) that may be incurred or issued pursuant to the foregoing by Non-Guarantor Subsidiaries shall not exceed $100.0 million at any one time outstanding.

Notwithstanding the first paragraph above, the Parent and its Restricted Subsidiaries may incur Permitted Debt.

For purposes of determining any particular amount of Debt under this “Limitation on debt” covenant, (x) Debt outstanding under the Credit Agreement and the Sumitomo Credit Agreement on the Issue Date shall at all times be treated as incurred pursuant to clause (i) of the definition of “Permitted Debt” and shall not be permitted to be reclassified and (y) guarantees or obligations with respect to letters of credit supporting Debt otherwise included in the determination of such particular amount shall not be included. Except as provided above, for purposes of determining compliance with this “Limitation on debt” covenant, in the event that an item of Debt meets the criteria of more than one of the types of Debt described above, including any Coverage Debt and any category of Permitted Debt, the Parent, in its sole discretion, shall classify, and from time to time may reclassify, all or any portion of such item of Debt. For purposes of determining compliance of any non-U.S. dollar-denominated Debt with this covenant, the amount outstanding under U.S. dollar-equivalent principal amount of Debt denominated in a foreign currency shall at all times be calculated based on the relevant currency exchange rate in effect on the date such Debt was incurred, in the case of any term Debt, or first committed, in the cases of any revolving credit Debt; provided, however, that if such Debt is incurred to Refinance other Debt denominated in the same or different currency, and such Refinancing would cause the applicable U.S. dollar-denominated restriction to be exceeded if calculated at the relevant currency exchange rate in effect on the date of such Refinancing, such U.S. dollar-denominated restriction shall be deemed not to have been exceeded so long as the principal amount of such Refinancing Debt does not exceed the principal amount of such indebtedness being Refinanced.

The accrual of interest, the accretion or amortization of original issue discount and the payment of interest on Debt in the form of additional Debt or payment of dividends on Capital Stock in the forms of additional shares of Capital Stock with the same terms will not be deemed to be an incurrence of Debt or issuance of Capital Stock for purposes of this covenant.

(a) The Parent will not, nor will the Parent permit any Restricted Subsidiary to, issue, assume or guarantee any Debt secured by a Lien upon any Principal Property or upon any shares of stock of any Restricted Subsidiary without effectively providing that the Notes of such series and the applicable Guarantee, together with, if the Parent so determines, any other indebtedness or obligation then existing or thereafter created, ranking equally in right of payment with such Notes or the applicable Guarantee, shall be secured equally and ratably with, or, at the Parent’s option, prior to, such Debt so long as such Debt shall be so secured, except that this restriction will not apply to:

(2) Liens affecting property of a Person existing at the time it becomes a Restricted Subsidiary or at the time it is merged into or consolidated with the Parent or a Restricted Subsidiary;

(4) Liens on property to secure all or part of the cost of repairing, altering, constructing, improving, exploring, drilling or developing such property, or to secure Debt incurred to provide funds for such purpose;

(6) Liens on current assets or other personal property, other than shares of stock of Subsidiaries, to secure loans maturing not more than one year from the date of the creation thereof or to secure any renewal thereof for not more than one year at any one time;

(7) Liens which secure indebtedness owing by a Restricted Subsidiary to the Parent or another Restricted Subsidiary of the Parent;

(8) Liens on property of any Restricted Subsidiary principally engaged in a financing or leasing business; and

(9) any extension, renewal or replacement, or successive extensions, renewals or replacements, in whole or in part, of any Lien referred to in the foregoing or of any Debt secured thereby; provided that the principal amount of Debt secured thereby shall not, with respect to Liens referred to in clauses (1) through (4) above, exceed the principal amount of Debt so secured at the time of such extension, renewal or replacement, and that such extension, renewal or replacement Lien shall be limited to all or part of substantially the same property which secured the Lien extended, renewed or replaced, plus improvements on such property.

(b) Notwithstanding the above provisions, the Parent and any one or more of its Restricted Subsidiaries may, without securing the Notes of such series and the applicable Guarantee, issue, assume or guarantee Debt secured by Liens which would not be permitted by the immediately preceding paragraph in an aggregate amount which, together with:

(1) the aggregate principal amount of all of the Parent’s other Debt and Debt of its Restricted Subsidiaries secured by a Lien upon any Principal Property or upon any shares of stock of any Restricted Subsidiary that would not be permitted to be secured by Liens under the immediately preceding paragraph; and

(2) the Attributable Debt in respect of Sale and Lease-Back Transactions existing at such time (other than Sale and Lease-Back Transactions in which the property involved would have been permitted to be secured under the immediately preceding paragraph or the proceeds of which have been applied in accordance with clause (a)(2) of the covenant described below under “—Limitation on sale and lease-back transactions” to the retirement of long-term indebtedness);

(c) For purposes of this covenant and the covenant described below under “—Limitation on sale and lease-back transactions,” the sale or other transfer of any interest in property of the character commonly referred to as a “production payment,” is not considered Debt secured by a Lien.

(a) The Parent will not, nor will the Parent permit any Restricted Subsidiary to, enter into any arrangement with any Person providing for the leasing by the Parent or any Restricted Subsidiary of any Principal Property, except for (x) temporary leases for terms of not more than three years, (y) leasing arrangements between the Parent and a Subsidiary or (z) leasing arrangements between Subsidiaries, title to which property has been or is to be sold or

transferred by the Parent or such Restricted Subsidiary to such Person (such transaction, a “Sale and Lease-Back Transaction”), unless the proceeds of any such sale are at least equal to the fair value, as determined by the Board of Directors of the Parent, of such property and either:

(1) the Parent or such Restricted Subsidiary would be permitted under paragraph (a) of the covenant described under “—Limitation on liens” to secure Debt by a Lien on the Principal Property to be leased in an amount at least equal to the Attributable Debt in respect of such Sale and Lease-Back Transaction without equally and ratably securing the Notes of such series pursuant to the terms of the covenant described under “—Limitation on liens”; or

(2) the Parent applies an amount equal to the fair value of the property so leased to the retirement, within 90 days of the effective date of any such Sale and Lease-Back Transaction, of the Issuer’s or the Parent’s long-term indebtedness which ranks senior or equal to the Notes of such series or the related Guarantee (other than indebtedness held by the Parent or any of its Subsidiaries).

Sale and Lease-Back Transactions do not include arrangements with governmental bodies entered into for the purpose of financing the purchase price or the cost of constructing or improving the property subject thereto.

(b) Notwithstanding the provisions of the preceding paragraph (a), the Parent or any of its Restricted Subsidiaries may enter into any Sale and Lease-Back Transaction which would not be permitted under the preceding paragraph (a) if the amount of the Attributable Debt in respect of such Sale and Lease-Back Transaction, together with:

(1) all of the Parent’s Debt and Debt of its Restricted Subsidiaries secured by a Lien on Principal Property or shares of stock of any Restricted Subsidiary and not permitted under paragraph (a) of the covenant described under “—Limitations on liens;” and

(2) all other Attributable Debt in respect of Sale and Lease-Back Transactions existing at such time (other than Sale and Lease-Back Transactions in which the property involved would have been permitted to have a Lien in accordance with clause (a) of the covenant described above under “—Limitations on liens,” or the proceeds of which have been applied in accordance with clause (2) of the preceding paragraph (a) to the retirement of long-term indebtedness) does not at the time exceed 10% of Consolidated Net Tangible Assets.

The Parent will not, and will not permit any of its Restricted Subsidiaries to, consummate an Asset Sale unless:

(1) the Parent (or the Restricted Subsidiary, as the case may be) receives consideration at the time of the Asset Sale at least equal to the fair market value of the assets or Capital Stock issued or sold or otherwise disposed of as determined by the Parent in good faith; and

(2) except in the case of a Permitted Asset Swap, at least 75% of the consideration received in the Asset Sale by the Parent or such Restricted Subsidiary is in the form of cash or Eligible Cash Equivalents. For purposes of this provision, each of the following will be deemed to be cash:

(a) any liabilities, as shown on the most recent consolidated balance sheet of the Parent or any Restricted Subsidiary (other than contingent liabilities and liabilities that are by their terms subordinated to the Notes or any Guarantee) that are assumed by the transferee of any such assets pursuant to a customary assignment and assumption agreement that releases the Parent or such Restricted Subsidiary from further liability;

(b) any securities, notes or other obligations received by the Parent or any such Restricted Subsidiary from such transferee that are converted by the Parent or such Restricted Subsidiary into cash within 180 days of their receipt to the extent of the cash received in that conversion; and

(c) any Designated Non-cash Consideration received by the Parent or such Restricted Subsidiary in such Asset Sale having an aggregate fair market value as determined by the Parent in good faith, taken

together with all other Designated Non-cash Consideration received pursuant to this clause (c) that is at that time outstanding, not to exceed $50.0 million at the time of the receipt of such Designated Non-cash Consideration, with the fair market value of each item of Designated Non-cash Consideration being measured at the time received and without giving effect to subsequent changes in value.

Within 360 days after the receipt of any Net Cash Proceeds from an Asset Sale, the Parent (or the applicable Restricted Subsidiary, as the case may be) may apply such Net Cash Proceeds at its option:

(i) to permanently repay (a) Debt under the Credit Agreement and, if the obligation repaid is revolving credit Debt, to correspondingly reduce commitments with respect thereto and/or (b) other unsecured Debt ranking pari passu in right of payment with the Notes of a series or the Parent’s Guarantee of such Notes (provided that if the Parent shall so reduce obligations under such other unsecured Debt, other than the Notes of such series, the Parent will (x) equally and ratably reduce obligations under the Notes of such series under any applicable optional redemption provisions or by open market purchases or (y) make an offer (in accordance with the procedures set forth below for an Asset Sale Offer) to all holders of such series to purchase at a purchase price equal to 100% of the principal amount thereof, plus accrued and unpaid interest and additional interest, if any, the pro rata principal amount of Notes of such series);

(ii) to acquire all or substantially all of the assets of, or any Capital Stock of, another Permitted Business, if, after giving effect to any such acquisition of Capital Stock, the Permitted Business is or becomes a Restricted Subsidiary of the Parent;

(iii) to make a capital expenditure in or that is used or useful in a Permitted Business or to make expenditures for maintenance, repair or improvement of existing properties and assets;

(iv) to acquire other assets (other than inventory) that are used or useful in a Permitted Business;

(v) to repay or repurchase Debt secured by the assets of the Parent or any Restricted Subsidiaries; or

Any Net Cash Proceeds from Asset Sales that are not applied, invested or subject to an offer to repurchase as provided in the preceding paragraph of this covenant will constitute “Excess Proceeds.” When the aggregate amount of Excess Proceeds with respect to a series of Notes exceeds $50.0 million, the Issuer will, within 30 days, make an Offer to Purchase to all Holders of such Notes (an “Asset Sale Offer”), and to all holders of other Debt containing provisions similar to those set forth in the applicable Indenture with respect to assets sales, to purchase the maximum aggregate principal amount of such Notes and such other Debt that may be purchased out of the Excess Proceeds. The offer price for the Notes of such series in any Offer to Purchase will be equal to 100% of the principal amount plus accrued and unpaid interest to the date of purchase, and will be payable in cash. If any Excess Proceeds remain after consummation of an Offer to Purchase in respect of such Notes, the Issuer may use those funds for any purpose not otherwise prohibited by the applicable Indenture and they will no longer constitute Excess Proceeds. If the aggregate principal amount of Notes of such series and other Debt tendered into such Offer to Purchase exceeds the amount of Excess Proceeds, the Excess Proceeds will be allocated between such Notes and such other Debt based on the principal amount (or accreted value, if applicable) of such Notes and such other Debt tendered and the Trustee will select the Notes of such series to be purchased on a pro rata basis among all such Notes tendered (subject to DTC procedures). Upon completion of each Offer to Purchase, the amount of Excess Proceeds will be reset at zero.

The Issuer will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of any Notes as a result of an Asset Sale Offer. To the extent that the provisions of any securities laws or regulations conflict with the Asset Sale Offer provisions of the Notes, the Issuer will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the Asset Sale Offer provisions of the Notes by virtue of such conflict.

After the Issue Date, the Parent will cause each Restricted Subsidiary of the Parent (other than the Issuer) that guarantees (i) the Credit Agreement or (ii) any Material Capital Markets Debt issued by the Parent, the Issuer or any Subsidiary Guarantor to, within 45 days of the incurrence of such guarantee, execute and deliver to the Trustee a supplemental indenture to the applicable Indenture pursuant to which such Restricted Subsidiary will guarantee payment of the applicable series of Notes on the same terms and conditions as those set forth in the applicable Indenture.

(a) upon the sale or other disposition (including by way of a consolidation or merger) of such Subsidiary Guarantor;

(b) upon the sale or disposition of all or substantially all assets of such Subsidiary Guarantor;

(c) at such time as such Subsidiary Guarantor no longer guarantees any (i) Credit Agreement or (ii) Material Capital Markets Debt of the Parent;

(d) upon defeasance of the Notes, as provided under “—Satisfaction and discharge of the indentures; defeasance;”

(e) at such time as such Subsidiary Guarantor is no longer a Restricted Subsidiary; or

in the case of clause (a) or (b), other than to the Parent or a Restricted Subsidiary of the Parent and as permitted by the Indentures.

Whether or not required by the SEC, so long as any Notes are outstanding, the Parent will furnish to the Holders, or file electronically with the SEC through the SEC’s Electronic Data Gathering, Analysis and Retrieval System (or any successor system), within the time periods specified in the SEC’s rules and regulations:

(1) all quarterly and annual financial information that would be required to be contained in a filing by the Parent with the SEC on Forms 10-Q and 10-K if the Parent were required to file such Forms, including a “Management’s discussion and analysis of financial condition and results of operations” and, with respect to the annual information only, a report on the annual financial statements by the Parent’s certified independent accountants; and

(2) all current reports that would be required to be filed by the Parent with the SEC on Form 8-K if the Parent were required to file such reports.

In addition, whether or not required by the SEC, the Parent will file a copy of all of the information and reports referred to in clauses (1) and (2) above with the SEC for public availability within the time periods specified in the SEC’s rules and regulations (unless the SEC will not accept such a filing) and make such information available to prospective investors. In addition, the Parent has agreed that, for so long as any Notes remain outstanding, it will furnish to the Holders of such Notes and to prospective investors, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act.

The Indenture with respect to each series of Notes provides that the Issuer will not merge or consolidate with any other Person or sell or convey all or substantially all of its assets to any Person, unless:

(1) the successor Person (if other than the Issuer) (the “Successor Issuer”) shall be a corporation organized under the laws of the United States or any state thereof and shall expressly assume (a) the due and punctual

payment of the principal of and premium, if any, and interest on all the Notes of such series, according to their tenor, and the due and punctual performance and observance of all of the covenants and conditions under the applicable Indenture to be performed or observed by the Issuer, by supplemental indenture satisfactory in form to the Trustee, executed and delivered to the Trustee by such Person and (b) all obligations of the Issuer under the Registration Rights Agreement, by a written instrument satisfactory in form to the parties thereto, executed and delivered to such parties by such Person;

(2) the Successor Issuer shall not, immediately after such merger or consolidation, or such sale or conveyance, be in default in the performance of any such covenant or condition;

(3) the Parent and each Subsidiary Guarantor (unless the Parent or such Subsidiary Guarantor is the other party to the transactions described above, in which case the preceding clause (1) shall apply) shall have by supplemental indenture confirmed that the applicable Guarantee shall apply to such Successor Issuer’s obligations under the applicable Indenture and the Notes of such series and shall have by written agreement confirmed that its obligations under the Registration Rights Agreement shall continue to be in effect; and

(4) the Issuer shall have provided the Trustee with an Opinion of Counsel and Officers’ Certificate confirming compliance with the applicable Indenture.

Subject to certain limitations, the Successor Issuer will succeed to, and be substituted for, the Issuer under the applicable Indenture, the Notes of such series and the Registration Rights Agreement.

The Indenture with respect to each series of Notes provides that the Parent will not merge or consolidate with any other Person or sell or convey all or substantially all of its assets to any Person, unless:

(1) the successor Person (if other than the Parent) (the “Successor Guarantor”) shall be a corporation organized under the laws of the United States or any state thereof and shall expressly assume by supplemental indenture satisfactory in form to the Trustee, executed and delivered to the Trustee by such Person all the obligations of the Parent under the applicable Guarantee, such Indenture and the Registration Rights Agreement;

(2) the Successor Guarantor shall not, immediately after such merger or consolidation, or such sale or conveyance, be in default in the performance of any such covenant or condition; and

(3) the Successor Guarantor shall have provided the Trustee with an Opinion of Counsel and Officers’ Certificate confirming compliance with such Indenture.

The Indenture with respect to each series of Notes provides that the Parent will not permit any Subsidiary Guarantor to merge or consolidate with any other Person or sell or convey all or substantially all of its assets to any Person, unless:

(1) (A) the successor Person (if other than the Parent, the Issuer or such Subsidiary Guarantor) (the “Successor Subsidiary Guarantor”) shall expressly assume by supplemental indenture satisfactory in form to the Trustee, executed and delivered to the Trustee by such Person all the obligations of such Subsidiary Guarantor under the applicable Guarantee and such Indenture;

(B) the Successor Subsidiary Guarantor shall not, immediately after such merger or consolidation, or such sale or conveyance, be in default in the performance of any such covenant or condition; and

(C) the Successor Subsidiary Guarantor shall have provided the Trustee with an Opinion of Counsel and Officers’ Certificate confirming compliance with such Indenture; or

(2) the merger, consolidation, sale or conveyance complies with the covenant described under “—Limitation on asset sales.”

Notwithstanding the foregoing, this covenant shall not apply to any transactions contemplated by the Separation Agreement or by the Merger Agreement.

Although there is a limited body of case law interpreting the phrase “substantially all,” 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 “all or substantially all” of the property or assets of a Person.

Upon any merger, consolidation or sale or conveyance of all or substantially all of the assets of the Parent, any Subsidiary Guarantor or the Issuer, as the case may be, in accordance with this covenant, the Parent, such Subsidiary Guarantor or the Issuer, as the case may be, will be released from its obligations under the Indentures, the Notes, the Guarantees and the Registration Rights Agreement, as applicable, and the Successor Issuer, the Successor Guarantor or the Successor Subsidiary Guarantor, as the case may be, will succeed to, and be substituted for, and may exercise every right and power of, the Parent, such Subsidiary Guarantor or the Issuer, as the case may be, under the Indentures, the Notes, the Registration Rights Agreement and the Guarantees, as applicable.

Following the first day (such date, the “Termination Date”) (a) the Notes of a series have a rating of Investment Grade from both S&P and Moody’s and (b) no Default has occurred and is continuing under the applicable Indenture, the Parent and its Restricted Subsidiaries will no longer be subject to the provisions of the applicable Indenture summarized under the headings above:

In the event that the applicable Notes’ credit rating is downgraded from Investment Grade by any Rating Agency, such covenants will not thereafter be reinstated. Promptly following the Termination Date, the Issuer will provide an Officers’ Certificate to the Trustee regarding such occurrence. The Trustee shall have no obligation to independently determine or verify if a Termination Date has occurred or notify the Holders of the Termination Date. The Trustee may provide a copy of such Officers’ Certificate to any Holder upon request. There can be no assurance that the Notes will ever achieve an Investment Grade rating.

Each of the following is an “Event of Default” with respect to a series of Notes:

(1) default in the payment in respect of the principal of, or premium, if any, on, any Note of such series when due and payable (whether at Stated Maturity or upon repurchase, acceleration, optional redemption or otherwise);

(2) default in the payment of any interest or Additional Interest (as required by the Registration Rights Agreement) upon any Note of such series when it becomes due and payable, and continuance of such default for a period of 30 days;

(3) default in the performance, or breach, of any covenant or agreement of the Parent or any Restricted Subsidiary in the applicable Indenture (other than a covenant or agreement a default in which performance or which breach is specifically dealt with in clauses (1) or (2) above), and continuance of such default or breach for a period of 60 days after written notice thereof has been given to the Issuer by the Trustee or to the Issuer and the Trustee by the Holders of at least 25% in aggregate principal amount of the outstanding Notes of such series (provided that, and without limiting the foregoing in this clause (3), in the case of a default or breach of any covenant or agreement described under “—Certain covenants—Provision of financial information,” no Event of Default shall occur (and any such default or breach shall be deemed to

not have occurred for all purposes under the applicable Indenture) with respect to any failure to furnish or file any information or report required thereunder if the Parent files or furnishes such information or report within 120 days after the Parent was required (or would have been required) to file the same pursuant to the SEC’s rules and regulations);

(4) the applicable Guarantee ceases to be in full force and effect (except as contemplated by the terms of the applicable Indenture) or is declared null and void in a judicial proceeding or the Parent or a Subsidiary Guarantor, as applicable, denies in writing or disaffirms in writing its obligations under the applicable Indenture or Guarantee, other than by reason of the termination of such Indenture or the release of such Guarantee in accordance with the terms of such Indenture; or

(5) certain events of bankruptcy, insolvency or reorganization affecting the Parent, the Issuer or any Significant Subsidiary.

A Default or Event of Default with respect to a series of Notes will not necessarily constitute a Default or Event of Default with respect to the other series of Notes.

If an Event of Default for any series of Notes (other than an Event of Default specified in clause (5) above with respect to the Parent or the Issuer) occurs and is continuing, then and in every such case the Trustee or the Holders of not less than 25% in aggregate principal amount of the outstanding Notes of the affected series may declare the principal of, premium, if any, and accrued and unpaid interest on the Notes of such series to be due and payable immediately by a notice in writing to the Issuer (and to the Trustee if given by such Holders); provided, however, that after such acceleration, but before a judgment or decree based on acceleration, the Holders of a majority in aggregate principal amount of the outstanding Notes of such series may rescind and annul such acceleration if all Events of Default, other than the nonpayment of accelerated principal of, premium, if any, or accrued and unpaid interest on the Notes of such series, have been cured or waived as provided in the applicable Indenture.

If an Event of Default for any series of Notes specified in clause (5) above occurs with respect to the Parent or the Issuer, the principal of, premium, if any, and accrued and unpaid interest on the Notes of such series then outstanding shall ipso facto become immediately due and payable without any declaration or other act on the part of the Trustee or any Holder of such Notes. For further information as to waiver of defaults, see “—Amendment, supplement and waiver.” The Trustee may withhold from Holders of a series notice of any Default (except any Default in the payment of principal of, premium, if any, or interest on the Notes of such series) if the Trustee determines that withholding notice is in the interests of such Holders to do so.

No Holder will have any right to institute any proceeding with respect to either Indenture or for any remedy thereunder, unless such Holder shall have previously given to the Trustee written notice of a continuing Event of Default with respect to a series of Notes and unless also the Holders of at least 25% in aggregate principal amount of the outstanding Notes of such series shall have made written request to the Trustee, and provided security and indemnity satisfactory to the Trustee, to institute such proceeding as Trustee, and the Trustee shall not have received from the Holders of a majority in aggregate principal amount of the outstanding Notes of such series a direction inconsistent with such request and shall have failed to institute such proceeding within 60 days. Such limitations do not apply, however, to a suit instituted by a Holder directly (as opposed to through the Trustee) for enforcement of payment of the principal of (and premium, if any) or interest on such Note on or after the respective due dates expressed in such Note.

The Issuer is required to furnish to the Trustee annually a statement as to the performance of certain obligations under the Indentures and as to any default in such performance. The Issuer also is required to notify the Trustee if it becomes aware of the occurrence of any Default and the steps to cure such Default.

Without the consent of any Holders, the Parent, the Issuer and the Trustee, at any time and from time to time, may amend or supplement either Indenture for any of the following purposes:

(1) to evidence the succession of another Person to the Parent, the Issuer or a Subsidiary Guarantor and the assumption by any such successor of the covenants of the Parent, the Issuer or such Subsidiary Guarantor, as applicable, under such Indenture, the related Notes and the Guarantees thereof;

(2) to add to the covenants of the Parent, the Issuer and the Subsidiary Guarantors for the benefit of the applicable Holders, or to surrender any right or power herein conferred upon the Parent, the Issuer and the Subsidiary Guarantors;

(4) to provide for uncertificated Notes of the relevant series in addition to or in place of the certificated Notes;

(5) to evidence and provide for the acceptance of appointment under such Indenture by a successor Trustee;

(6) to provide for or confirm the issuance of Additional Notes of a series in accordance with the terms of such Indenture;

(7) to add a Subsidiary Guarantor in accordance with such Indenture or release (a) the Parent in accordance with the “Consolidation, merger, conveyance, transfer or lease” provisions of such Indenture or (b) a Subsidiary Guarantor from its Guarantee when permitted by the terms of such Indenture;

(9) to make any other provisions with respect to matters or questions arising under such Indenture; provided, however, that such actions pursuant to this clause (9) shall not adversely affect the interests of the Holders of the relevant series in any material respect, as determined in good faith by the Board of Directors of the Parent;

(10) to provide for the issuance of a series of Exchange Notes, which shall be treated, together with any outstanding Notes of such series, as a single class of securities;

(11) to conform the text of such Indenture or the related Notes to any provision of the “Description of notes” section of the offering memorandum dated September 25, 2015 related to the offer and sale of the Original Notes to the extent that the Trustee has received an Officers’ Certificate stating that such text constitutes an unintended conflict with the description of the corresponding provision in such “Description of notes;” or

(12) to effect or maintain the qualification of such Indenture under the Trust Indenture Act.

With the consent of the Holders of not less than a majority in aggregate principal amount of the outstanding Notes of each series that would be affected by such amendment or supplement, the Parent, the Issuer and the Trustee may amend or supplement the applicable Indenture for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of such Indenture applicable to the Notes of such series or the related Guarantee, or of the Notes of such series or the related Guarantee, or of modifying in any manner the rights of the Holders of such series under such Indenture, including the definitions therein; provided, however, that no such amendment or supplement shall, without the consent of the Holder of each outstanding Note affected thereby:

(1) change the Stated Maturity of any Note or of any installment of interest on any Note, or reduce the amount payable in respect of the principal thereof or the rate of interest thereon or any premium payable thereon, or reduce the amount that would be due and payable on acceleration of the maturity thereof, or change the place of payment where, or the coin or currency in which, any Note or any premium or interest thereon is payable, or impair the right to institute suit for the enforcement of any such payment on or after the Stated Maturity thereof, or change the date on which any Notes may be subject to redemption or reduce the redemption price therefor;

(2) reduce the percentage in aggregate principal amount of the outstanding Notes of a series, the consent of whose Holders is required for any such amendment or supplement, or the consent of whose Holders is required for any waiver (of compliance with certain provisions of the applicable Indenture or certain defaults thereunder and their consequences) provided for in the applicable Indenture;

(3) modify the obligations of the Issuer to make offers to purchase upon a Change of Control if such modification was done after the occurrence of the related Change of Control;

(4) modify or change any provision of such Indenture affecting the ranking of the applicable Notes in a manner adverse to the applicable Holders; or

(5) modify any of the provisions of this paragraph or provisions relating to waiver of defaults or certain covenants, except to increase any such percentage required for such actions or to provide that certain other provisions of such Indenture cannot be modified or waived without the consent of the Holder of each outstanding Note issued thereunder that is affected thereby.

The Holders of not less than a majority in aggregate principal amount of the outstanding Notes of a series may on behalf of the Holders of all the Notes of such series waive any past default under the applicable Indenture and its consequences, except a default:

(1) in any payment in respect of the principal of (or premium, if any) or interest on any Notes of such series (including any Note which is required to have been purchased pursuant to a Change of Control which has been made by the Issuer); or

(2) in respect of a covenant or provision hereof which under such Indenture cannot be modified or amended without the consent of the Holder of each outstanding Note issued thereunder that is affected.

The consent of the Holders is not necessary under the Indentures to approve the particular form of any proposed amendment, supplement or waiver. It is sufficient if such consent approves the substance of the proposed amendment or supplement. A consent to any amendment, supplement or waiver under the Indentures by any Holder given in connection with a tender of such Holder’s Notes will not be rendered invalid by such tender.

An amendment, supplement or waiver of a provision applicable to one series of Notes will not affect the rights of holders of the other series of Notes.

The Issuer, the Parent and the Subsidiary Guarantors may terminate their respective obligations under the applicable Indenture with respect to the series of Notes issued thereunder when either:

(1) all Notes of such series theretofore authenticated and delivered have been delivered to the Trustee for cancellation; or

(b) the Issuer, the Parent or the applicable Subsidiary Guarantor has paid or caused to be paid all other sums then due and payable under such Indenture by the Issuer with respect to the Notes of such series;

(c) the deposit will not result in a breach or violation of, or constitute a default under, any instrument (other than such Indenture) to which the Issuer, the Parent or any Subsidiary Guarantor is a party or by which the Issuer, the Parent or the applicable Subsidiary Guarantor is bound;

(d) the Issuer has delivered irrevocable instructions to the Trustee under the applicable Indenture to apply the deposited money toward the payment of the Notes of such series at maturity or on the redemption date, as the case may be; and

(e) the Issuer has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel each stating that all conditions precedent under such Indenture relating to the Discharge have been complied with.

The Issuer may elect, at its option, to have the obligations of the Issuer, the Parent and the Subsidiary Guarantors discharged with respect to the outstanding Notes of any series (“defeasance”). Such defeasance means that the Issuer will be deemed to have paid and discharged the entire indebtedness represented by the outstanding Notes of such series, except for:

(1) the rights of Holders of such Notes to receive payments in respect of the principal of and premium, if any, and interest on such Notes when payments are due;

(2) the Issuer’s obligations with respect to such Notes concerning issuing temporary Notes, registration of Notes, mutilated, destroyed, lost or stolen Notes and the maintenance of an office or agency for payment and money for security payments held in trust;

In addition, the Issuer may elect, at its option, to have the obligations of the Issuer, the Parent and the Subsidiary Guarantors released with respect to certain covenants applicable to a series of Notes, including, without limitation, the Issuer’s obligation to make offers to purchase in connection with any Change of Control, in the applicable Indenture (“covenant defeasance”) and any omission to comply with such obligations shall not constitute a Default or an Event of Default with respect to such Notes. In the event covenant defeasance occurs, clauses (3), (4) and (5) (solely with respect to the Parent or any Significant Subsidiary) described under “Events of default” will no longer constitute an Event of Default with respect to the Notes of such series.

In order to exercise either defeasance or covenant defeasance with respect to outstanding Notes of any series:

(1) the Issuer must irrevocably have deposited or caused to be deposited with the Trustee as trust funds in trust for the purpose of making the following payments, specifically pledged as security for, and dedicated solely to the benefit of the Holders of such Notes: (A) money in an amount, (B) U.S. government obligations, which through the scheduled payment of principal and interest in respect thereof in accordance with their terms will provide, not later than the due date of any payment, money in an amount or (C) a combination thereof, in each case sufficient without reinvestment, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, to pay and discharge, and which shall be applied by the Trustee to pay and discharge, the entire indebtedness in respect of the principal of and premium, if any, and interest on such Notes on the Stated Maturity thereof or (if the Issuer has made irrevocable arrangements satisfactory to the Trustee for the giving of notice of redemption in the name and at the expense of the Issuer) the redemption date thereof, as the case may be, in accordance with the terms of the applicable Indenture and such Notes;

(2) in the case of defeasance, the Issuer shall have delivered to the Trustee an Opinion of Counsel stating that (A) the Issuer has received from, or there has been published by, the Internal Revenue Service a ruling or (B) since the date of the applicable Indenture, there has been a change in the applicable United States federal income tax law, in either case (A) or (B) to the effect that, and based thereon such opinion shall confirm that, the Holders of such Notes will not recognize gain or loss for United States federal income tax purposes as a result of the deposit, defeasance and discharge to be effected with respect to such Notes and will be subject to United States federal income tax on the same amount, in the same manner and at the same times as would be the case if such deposit, defeasance and discharge were not to occur;

(3) in the case of covenant defeasance, the Issuer shall have delivered to the Trustee an Opinion of Counsel to the effect that the Holders of such outstanding Notes will not recognize gain or loss for United States federal income tax purposes as a result of the deposit and covenant defeasance to be effected with respect to such Notes and will be subject to federal income tax on the same amount, in the same manner and at the same times as would be the case if such deposit and covenant defeasance were not to occur;

(4) no Default with respect to the outstanding Notes of such series shall have occurred and be continuing at the time of such deposit after giving effect thereto (other than a Default resulting from the borrowing of funds to be applied to such deposit and the grant of any Lien to secure such borrowing);

(5) such defeasance or covenant defeasance shall not result in a breach or violation of, or constitute a default under, any material agreement or material instrument (other than the applicable Indenture) to which the Parent, the Issuer or any Subsidiary Guarantor is a party or by which the Parent, the Issuer or any Subsidiary Guarantor is bound; and

(6) the Issuer shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent with respect to such defeasance or covenant defeasance have been complied with.

Notwithstanding the foregoing, the Opinion of Counsel required by clause (2) or (3) above with respect to a defeasance or covenant defeasance need not to be delivered if all Notes of such series not theretofore delivered to the Trustee for cancellation (x) have become due and payable or (y) will become due and payable at Stated Maturity within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Issuer.

U.S. Bank National Association is the Trustee under the Indentures and has been appointed by the Issuer as registrar and paying agent with regard to the Notes.

If the Trustee becomes a creditor of the Issuer or the Parent, each 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 claim as security or otherwise. The Trustee will be permitted to engage in other transactions; however, if it acquires any conflicting interest it must eliminate such conflict within 90 days, apply to the SEC for permission to continue as Trustee (if the applicable Indenture has been qualified under the Trust Indenture Act) or resign.

The Holders of a majority in principal amount of the outstanding Notes of a series will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee with respect to the Notes of such series or exercising any trust or power conferred on the Trustee with respect to such Notes, subject to certain exceptions. Except during the continuance of an Event of Default, the Trustee will perform only such duties as are specifically set forth in the applicable Indenture. During the continuance of an Event of Default that has not been cured or waived, the Trustee will exercise such of the rights and powers vested in it by the applicable Indenture, and use the same degree of care and skill in their exercise, as a prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs. Subject to such provisions, the Trustee shall be under no obligation to exercise any of the rights or powers vested in it by the applicable Indenture with respect to the Notes of a series at the request or direction of any of the holders of the Notes of a series pursuant to the applicable Indenture, unless such holders shall have provided to the Trustee security or indemnity satisfactory to the Trustee against the costs, expenses and liabilities which might be incurred by it in compliance with such request or direction.

Notwithstanding any other provision of the Indentures or any Note, where the Indentures or any Note provide for notice of any event (including any notice of redemption) to any Holder of an interest in a global Note (whether

by mail or otherwise), such notice shall be sufficiently given if given to DTC or any other applicable depositary for such Note (or its designee) in accordance with the applicable procedures of DTC or such depositary.

No past, present or future director, officer, employee, incorporator, member, partner or stockholder of the Issuer or the Parent, as such, shall have any liability for any obligations of the Issuer or the Parent (other than the Issuer in respect of the Notes and the Parent and the Subsidiary Guarantors in respect of the Guarantees) under the Notes, the Guarantees or the Indentures or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes.

The Indentures, the Notes and the Guarantees are governed by, and will be construed in accordance with, the laws of the State of New York.

“Consolidated EBITDA” means, for any period, Consolidated Net Income for such period (adjusted to exclude all extraordinary or unusual items and any gains or losses on sales of assets outside the ordinary course of business) plus, without duplication and (except with respect to synergies included in Consolidated Cost Savings) to the extent deducted in calculating such Consolidated Net Income for such period, the sum of (a) income tax expense, (b) interest expense, amortization or writeoff of debt discount with respect to Debt, (c) depreciation and amortization expense, (d) amortization of intangibles (including, but not limited to, goodwill) and organization costs, (e) Consolidated Cost Savings; provided that with respect to any period, the aggregate amount added back in the calculation of Consolidated EBITDA for such period pursuant to this clause (e) and clause (f) below shall not exceed 20% of Consolidated EBITDA (in each case calculated prior to giving effect to any add-backs pursuant to this clause (e) and clause (f) below), (f) costs and expenses incurred in connection with the implementation of Initiatives; provided that with respect to any period, the aggregate amount added back in the calculation of Consolidated EBITDA for such period pursuant to this clause (f) and clause (e) above shall not exceed 20% of Consolidated EBITDA (in each case calculated prior to giving effect to any add-backs pursuant to this clause (f) and clause (e) above), (g) the sum (without duplication) of all non-recurring fees, costs and expenses incurred by the Parent and its Restricted Subsidiaries, whether before, on or within six months after the Merger Closing Date, in connection with the Transactions during such period; provided that the aggregate amount added back in the calculation of Consolidated EBITDA pursuant to this clause (g) shall not exceed $100,000,000, (h) all payments triggered in respect of the Parent’s non-qualified deferred compensation and post-retirement benefit plans in connection with the Transactions during such period, (i) any other non-cash charges and (j) adjustments and add-backs of the nature set forth in the offering memorandum dated September 25, 2015 related to the offer and sale of the Original Notes, minus, (x) any cash payments made during such period in respect of items described in clause (i) above subsequent to the fiscal quarter in which the relevant non-cash charge was reflected as a charge in the statement of Consolidated Net Income and (y) to the extent included in calculating such Consolidated Net Income for such period, any non-cash income (other than amounts accrued in the ordinary course of business under accrual-based revenue recognition procedures in accordance with GAAP).

“Consolidated Fixed Charge Coverage Ratio” means, with respect to any Person, the ratio of Consolidated EBITDA of such Person during the four full fiscal quarters for which financial statements are available (the “Four Quarter Period”) ending prior to the date of the transaction giving rise to the need to calculate the Consolidated Fixed Charge Coverage Ratio (the “Transaction Date”) to Consolidated Fixed Charges of such

(ii) any Asset Sales or Asset Acquisitions (including, without limitation, any Asset Acquisition giving rise to the need to make such calculation as a result of such Person or one of its Restricted Subsidiaries (including any Person who becomes a Restricted Subsidiary as a result of the Asset Acquisition) incurring, assuming or otherwise being liable for Acquired Debt and also including any Consolidated EBITDA attributable to the assets which are the subject of the Asset Acquisition) occurring during the Four Quarter Period or at any time subsequent to the last day of the Four Quarter Period and on or prior to the Transaction Date, as if such Asset Sale or Asset Acquisition (including the incurrence, assumption or liability for any such Acquired Debt) occurred on the first day of the Four Quarter Period.

Furthermore, in calculating “Consolidated Fixed Charges” for purposes of determining the denominator (but not the numerator) of this “Consolidated Fixed Charge Coverage Ratio”:

(i) interest on outstanding Debt determined on a fluctuating basis as of the Transaction Date and which will continue to be so determined thereafter shall be deemed to have accrued at a fixed rate per annum equal to the rate of interest on such Debt in effect on the Transaction Date;

(ii) if interest on any Debt actually incurred on the Transaction Date may optionally be determined at an interest rate based upon a factor of a prime or similar rate, a eurocurrency interbank offered rate, or other rates, then the interest rate in effect on the Transaction Date will be deemed to have been in effect during the Four Quarter Period; and

(iii) notwithstanding clause (i) or (ii) above, interest on Debt determined on a fluctuating basis, to the extent such interest is covered by agreements relating to Hedging Obligations, shall be deemed to accrue at the rate per annum resulting after giving effect to the operation of such agreements.

“Consolidated Fixed Charges” means, with respect to any Person for any period, the sum of, without duplication, the amounts for such period of:

(ii) the product of (a) all dividends and other distributions accrued during such period in respect of Redeemable Capital Interests and preferred stock of such Person and its Restricted Subsidiaries (other than dividends paid in Qualified Capital Interests), times (b) a fraction, the numerator of which is one and the denominator of which is one minus the then current combined federal, state and local statutory tax rate of such Person, expressed as a decimal.

“Consolidated Interest Expense” means, with respect to any Person for any period, without duplication, the sum of:

(i) the total interest expense of such Person and its Restricted Subsidiaries for such period as determined on a consolidated basis in accordance with GAAP, including, without limitation:

(d) all commissions, discounts and other fees and charges owed with respect to financing activities or similar activities; and

(a) any Unrestricted Subsidiary must be an entity of which the Capital Stock entitled to cast at least a majority of the votes that may be cast by all Capital Stock having ordinary voting power for the election of directors or other governing body are owned, directly or indirectly, by the Parent,

(b) such designation complies with the covenants described under “Certain covenants—Limitation on restricted payments” and

has not at the time of designation, and does not thereafter, create, incur, issue, assume, guarantee or otherwise become directly or indirectly liable with respect to any Debt pursuant to which the lender has recourse to any of the assets of the Parent or any Restricted Subsidiary.

The Board of Directors of the Parent may designate any Unrestricted Subsidiary to be a Restricted Subsidiary; provided that immediately after giving effect to such designation no Default or Event of Default shall have occurred and be continuing and either:

(1) the Parent could incur at least $1.00 of additional Debt pursuant to the Consolidated Fixed Charge Coverage Ratio test described under “Certain covenants—Limitation on debt” or

(2) the Consolidated Fixed Charge Coverage Ratio for the Parent and the Restricted Subsidiaries on a consolidated basis would be greater than or equal to such ratio for the Parent and the Restricted Subsidiaries on a consolidated basis immediately prior to such designation, in each case on a pro forma basis taking into account such designation.

Any such designation by the Board of Directors of the Parent shall be notified by the Issuer to the Trustee by promptly filing with the Trustee a copy of a resolution of the board of directors of the Issuer giving effect to such designation and an Officers’ Certificate certifying that such designation complied with the foregoing provisions.

“Voting Stock” of a Person means all classes of Capital Stock of such Person then outstanding and normally entitled (without regard to the occurrence of any contingency) to vote in the election of directors (or Persons performing similar functions).

The Exchange Notes will be issued in the form of one or more registered notes in global form, without interest coupons (the “global notes”).

Upon issuance, each of the global notes will be deposited with the trustee as custodian for DTC and registered in the name of Cede & Co., as nominee of DTC.

Ownership of beneficial interests in each global note will be limited to persons who have accounts with DTC (“DTC participants”) or persons who hold interests through DTC participants. We expect that under procedures established by DTC:

Beneficial interests in the global notes may not be exchanged for notes in physical, certificated form except in the limited circumstances described below.

All interests in the global notes will be subject to the operations and procedures of DTC, Euroclear and Clearstream. We provide the following summaries of those operations and procedures solely for the convenience of investors. The operations and procedures of each settlement system are controlled by that settlement system and may be changed at any time. Neither we nor the initial purchasers are responsible for those operations or procedures.

DTC was created to hold securities for its participants and to facilitate the clearance and settlement of securities transactions between its participants through electronic book-entry changes to the accounts of its participants. DTC’s participants include securities brokers and dealers, including the initial purchasers; banks and trust companies; clearing corporations and other organizations. Indirect access to DTC’s system is also available to others such as banks, brokers, dealers and trust companies; these indirect participants clear through or maintain a custodial relationship with a DTC participant, either directly or indirectly. Investors who are not DTC participants may beneficially own securities held by or on behalf of DTC only through DTC participants or indirect participants in DTC.

So long as DTC’s nominee is the registered owner of a global note, that nominee will be considered the sole owner or holder of the notes represented by that global note for all purposes under the indentures. Except as provided below, owners of beneficial interests in a global note:

As a result, each investor who owns a beneficial interest in a global note must rely on the procedures of DTC to exercise any rights of a holder of notes under the indentures (and, if the investor is not a participant or an indirect participant in DTC, on the procedures of the DTC participant through which the investor owns its interest).

Payments of principal, premium (if any) and interest with respect to the notes represented by a global note will be made by the trustee to DTC’s nominee as the registered holder of the global note. Neither we nor the trustee will have any responsibility or liability for the payment of amounts to owners of beneficial interests in a global note, for any aspect of the records relating to or payments made on account of those interests by DTC, or for maintaining, supervising or reviewing any records of DTC relating to those interests.

Payments by participants and indirect participants in DTC to the owners of beneficial interests in a global note will be governed by standing instructions and customary industry practice and will be the responsibility of those participants or indirect participants and DTC.

Transfers between participants in DTC will be effected under DTC’s procedures and will be settled in same-day funds. Transfers between participants in Euroclear or Clearstream will be effected in the ordinary way under the rules and operating procedures of those systems.

Cross-market transfers between DTC participants, on the one hand, and Euroclear or Clearstream participants, on the other hand, will be effected within DTC through the DTC participants that are acting as depositaries for Euroclear and Clearstream. To deliver or receive an interest in a global note held in a Euroclear or Clearstream account, an investor must send transfer instructions to Euroclear or Clearstream, as the case may be, under the rules and procedures of that system and within the established deadlines of that system. If the transaction meets its settlement requirements, Euroclear or Clearstream, as the case may be, will send instructions to its DTC depositary to take action to effect final settlement by delivering or receiving interests in the relevant global notes in DTC, and making or receiving payment under normal procedures for same-day funds settlement applicable to DTC. Euroclear and Clearstream participants may not deliver instructions directly to the DTC depositaries that are acting for Euroclear or Clearstream.

Because of time zone differences, the securities account of a Euroclear or Clearstream participant that purchases an interest in a global note from a DTC participant will be credited on the business day for Euroclear or Clearstream immediately following the DTC settlement date. Cash received in Euroclear or Clearstream from the sale of an interest in a global note to a DTC participant will be received with value on the DTC settlement date but will be available in the relevant Euroclear or Clearstream cash account as of the business day for Euroclear or Clearstream following the DTC settlement date.

DTC, Euroclear and Clearstream have agreed to the above procedures to facilitate transfers of interests in the global notes among participants in those settlement systems. However, the settlement systems are not obligated to perform these procedures and may discontinue or change these procedures at any time. Neither we nor the trustee will have any responsibility for the performance by DTC, Euroclear or Clearstream or their participants or indirect participants of their obligations under the rules and procedures governing their operations.

Notes in physical, certificated form will be issued and delivered to each person that DTC identifies as a beneficial owner of the related notes only if:

The exchange of Original Notes for Exchange Notes in the exchange offers described herein will not constitute a significant modification of the terms of the Notes under applicable tax rules and thus will not constitute a taxable exchange for the beneficial owners of the Notes for United States federal income tax purposes. Consequently, a beneficial owner of Notes will not recognize gain or loss on the exchange of Original Notes for Exchange Notes pursuant to the exchange offers, the holding period of the Exchange Notes will include the holding period of the Original Notes surrendered in exchange therefor and the beneficial owner’s adjusted tax basis in the Exchange Notes will be the same as its adjusted tax basis in the Original Notes surrendered in exchange therefor immediately before the exchange. The exchange of Original Notes for Exchange Notes pursuant to the exchange offers will not otherwise affect the United States federal income tax consequences of holding and disposing of Notes. Beneficial owners of Notes should consult their own tax advisors regarding the United States federal income tax consequences of holding and disposing of Notes.

The following is a summary of certain considerations associated with the purchase, holding and disposition of the Notes by employee benefit plans that are subject to Title I of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”), plans, individual retirement accounts and other arrangements that are subject to Section 4975 of the Internal Revenue Code of 1986, as amended (the “Code”) or provisions under any federal, state, local, non-U.S. or other laws or regulations that are similar to such provisions of ERISA or the Code (collectively, “Similar Laws”), and entities whose underlying assets are considered to include “plan assets” of any such plan, account or arrangement (each, a “Plan”).

ERISA and the Code impose certain duties on persons who are fiduciaries of a Plan subject to Title I of ERISA or Section 4975 of the Code (an “ERISA Plan”) and prohibit certain transactions involving the assets of an ERISA Plan and its fiduciaries or other interested parties. Under ERISA and the Code, any person who exercises any discretionary authority or control over the administration of an ERISA Plan or the management or disposition of the assets of an ERISA Plan, or who renders investment advice for a fee or other compensation to an ERISA Plan, is generally considered to be a fiduciary of the ERISA Plan.

In considering an investment in the Notes of a portion of the assets of any Plan, a fiduciary should determine whether the investment is in accordance with the documents and instruments governing the Plan and the applicable provisions of ERISA, the Code or any Similar Law relating to a fiduciary’s duties to the Plan including, without limitation, the prudence, diversification, delegation of control and prohibited transaction provisions of ERISA, the Code and any other applicable Similar Laws.

Section 406 of ERISA and Section 4975 of the Code prohibit ERISA Plans from engaging in specified transactions involving plan assets with persons or entities who are “parties in interest,” within the meaning of ERISA, or “disqualified persons,” within the meaning of Section 4975 of the Code, unless an exemption is available. A party in interest or disqualified person who engages in a non-exempt prohibited transaction may be subject to excise taxes and other penalties and liabilities under ERISA and the Code. In addition, the fiduciary of the ERISA Plan that engages in such a non-exempt prohibited transaction may be subject to penalties and liabilities under ERISA and the Code. The acquisition and/or holding of Notes (including in connection with the exchange of Original Notes for Exchange Notes) by an ERISA Plan with respect to which the Issuer, the initial purchasers, participants in the exchange offers or Olin are considered a party in interest or a disqualified person may constitute or result in a direct or indirect prohibited transaction under Section 406 of ERISA and/or Section 4975 of the Code, unless the investment is acquired and is held in accordance with an applicable statutory, class or individual prohibited transaction exemption.

In this regard, the U.S. Department of Labor has issued prohibited transaction class exemptions, or “PTCEs,” that may provide exemptive relief for direct or indirect prohibited transactions resulting from the purchase, holding or disposition of the Original Notes or Exchange Notes and, the exchange of the Original Notes for Exchange Notes. These class exemptions include, without limitation, PTCE 84-14 respecting transactions determined by independent qualified professional asset managers, PTCE 90-1 respecting insurance company pooled separate accounts, PTCE 91-38 respecting bank collective investment funds, PTCE 95-60 respecting life insurance company general accounts, and PTCE 96-23 respecting transactions determined by in-house asset managers. In addition, Section 408(b)(17) of ERISA and Section 4975(d)(20) of the Code provide relief from the prohibited transaction provisions of ERISA and Section 4975 of the Code for certain transactions, provided that neither the Issuer nor any of its affiliates (directly or indirectly) have or exercise any discretionary authority or control or render any investment advice with respect to the assets of any ERISA Plan involved in the transaction and provided further that the ERISA Plan pays no more than adequate consideration in connection with the transaction. There can be no assurance that all of the conditions of any such exemptions will be satisfied.

Because of the foregoing, the Original Notes and Exchange Notes should not be purchased or held by any person investing “plan assets” of any Plan, unless such purchase and holding (and the exchange of the Original Notes for Exchange Notes) will not constitute a non-exempt prohibited transaction under ERISA and the Code or similar violation of any applicable Similar Laws.

Accordingly, by acceptance of an Exchange Note each purchaser and subsequent transferee will be deemed to have represented and warranted that either (i) no portion of the assets used by such purchaser or transferee to acquire or hold the Original Notes or the Exchange Notes constitutes assets of any Plan or (ii) the purchase and holding of the Notes and the exchange of the Original Notes for Exchange Notes by such purchaser or transferee will not constitute a non-exempt prohibited transaction under Section 406 of ERISA or Section 4975 of the Code or similar violation under any applicable Similar Laws.

The foregoing discussion is general in nature and is not intended to be all-inclusive. Due to the complexity of these rules and the penalties that may be imposed upon persons involved in non-exempt prohibited transactions, it is particularly important that fiduciaries, or other persons considering purchasing the Notes (and/or holding the Notes or exchanging Original Notes for Exchange Notes) on behalf of, or with the assets of, any Plan, consult with their counsel regarding the potential applicability of ERISA, Section 4975 of the Code and any Similar Laws to such investment and whether an exemption would be applicable to the purchase and holding of the Original Notes or the Exchange Notes (including in connection with the exchange of Original Notes for Exchange Notes).

Purchasers of the Original Notes or Exchange Notes have the exclusive responsibility for ensuring that their purchase and holding of the Original Notes or Exchange Notes (including in connection with the exchange of Original Notes for Exchange Notes) complies with the fiduciary responsibility rules of ERISA and does not violate the prohibited transaction rules of ERISA, the Code or applicable Similar Laws.

Each broker-dealer that receives Exchange Notes for its own account pursuant to an exchange offer must acknowledge that it will deliver a prospectus in connection with any resale of such Exchange Notes. This prospectus, as it may be amended or supplemented from time to time, may be used by a broker-dealer in connection with resales of Exchange Notes received in exchange for Original Notes where such Original Notes were acquired by it as a result of market-making activities or other trading activities. We have agreed that, starting on the expiration date and ending at the close of business on the date that is 180 days after the expiration date, we will make this prospectus, as amended or supplemented, available to any broker-dealer for use in connection with any such resale.

We will not receive any proceeds from any sale of Exchange Notes by broker-dealers. Exchange Notes received by broker-dealers for their own account pursuant to the exchange offers may be sold from time to time in one or more transactions in the over-the-counter market, in negotiated transactions, through the writing of options on the Exchange Notes or a combination of such methods of resale, at market prices prevailing at the time of resale, at prices related to such prevailing market prices or at negotiated prices. Any such resale may be made directly to purchasers or to or through brokers or dealers who may receive compensation in the form of commissions or concessions from any such broker-dealer and/or the purchasers of any such Exchange Notes. Any broker-dealer that resells Exchange Notes that were received by it for its own account pursuant to an exchange offer and any broker or dealer that participates in a distribution of such Exchange Notes may be deemed to be an “underwriter” within the meaning of the Securities Act, and any profit of any such resale of Exchange Notes and any commissions or concessions received by any such persons may be deemed to be underwriting compensation under the Securities Act. The letter of transmittal states that by acknowledging that it will deliver and by delivering a prospectus, a broker-dealer will not be deemed to admit that it is an “underwriter” within the meaning of the Securities Act.

For a period of 180 days after the expiration date, we will promptly send additional copies of this prospectus and any amendment or supplement to this prospectus to any broker-dealer that requests such documents. We have agreed to pay all expenses incident to the performance of our obligations under the Registration Rights Agreement related to the exchange offers other than fees and expenses of counsel for holders, commissions and transfer taxes, and we have agreed to indemnify the holders of the Notes (including any broker-dealers) against certain liabilities, including certain liabilities under the Securities Act.

The validity of the Exchange Notes and guarantees offered hereby and certain other legal matters will be passed upon for us by Cravath, Swaine & Moore LLP, New York, New York (with respect to New York law) and Hunton & Williams LLP, Richmond, Virginia (with respect to Virginia law).

Olin is incorporated in Virginia. Under Virginia law, to the extent provided in its articles of incorporation or its shareholder approved bylaws, a corporation may eliminate a director’s or an officer’s personal liability for monetary damages in any proceeding brought by or in the right of a corporation or brought by or on behalf of shareholders, except for liability resulting from such director’s or officer’s willful misconduct or a knowing violation of criminal law or of any federal or state securities law.

Olin’s Bylaws (the “Olin Bylaws”) provide that the directors and officers shall not be liable for monetary damages to Olin or its shareholders with respect to any transaction, occurrence or course of conduct, except for liability resulting from such director’s or officer’s willful misconduct or a knowing violation of the criminal law or any federal or state securities law.

Under Virginia law, a corporation may indemnify any person made a party to a proceeding because he or she is or was a director or officer against liability incurred in the proceeding if he or she acted in good faith and in a manner he or she believed to be in the best interests of the corporation (or not opposed to such interests if he or she is acting outside his or her official capacity with the corporation), and in the case of any criminal proceeding, he or she had no reasonable cause to believe his or her conduct was unlawful. Virginia law also provides that a corporation has the power to make any further indemnity, including indemnity with respect to a proceeding by or in the right of the corporation, and may make additional provisions for advances and reimbursement of expenses, if authorized by its articles of incorporation or shareholder approved bylaws or resolution, except indemnity against willful misconduct or a knowing violation of criminal law.

The Olin Bylaws provide that Olin shall indemnify any director, officer or employee of Olin, or any person who, at the request of Olin, serves or has served in any such capacity with another corporation, partnership, joint venture, trust, employee benefit plan, or other enterprise, in each case against any and all liability and reasonable expense that may be incurred by him or her in connection with or resulting from any claim, action or proceeding (whether brought in the right of Olin or any such other corporation, entity, plan or otherwise), civil or criminal, in which he or she may become involved, as a party or otherwise, by reason of his or her being or having been a director, officer or employee of Olin, or such other corporation, entity or plan while serving at the request of Olin, whether or not he or she continues to be such at the time such liability or expense shall have been incurred, unless such person engaged in willful misconduct or a knowing violation of the criminal law.

Virginia law provides that any indemnification for a director or officer, unless ordered by a court, is subject to a determination that the director or officer has met the relevant standard of conduct. The determination will be made:

The Olin Bylaws provide that any indemnification of a director, officer or employee shall be made unless: the board of directors, acting by a majority vote of those directors who were directors at the time of the

occurrence giving rise to the claim for indemnification and who are not at the time parties to such claim (provided that there are at least five such directors), finds that the person seeking indemnification has not met the standards of conduct set forth in the Olin Bylaws; or if there are not five such directors, Olin’s principal Virginia legal counsel, as last designated by the Olin Board before the occurrence of the event giving rise to the claim for indemnification, or in the event such Virginia legal counsel is unwilling to serve, then Virginia legal counsel mutually acceptable to Olin and the person seeking indemnification, delivers to Olin its written legal advice that, in such counsel’s opinion, the person seeking indemnification has not met the standards of conduct set forth in the Olin Bylaws.

Under Virginia law, a corporation may advance expenses before the final disposition of a proceeding if:

Under Virginia law, unless limited by a corporation’s articles of incorporation, to the extent that a director or officer has been successful on the merits or otherwise in defense of the proceeding, the director or officer must be indemnified against reasonable expenses incurred by him or her in connection with that proceeding.

Under the Olin Bylaws, Olin is required to advance expenses incurred by a director, officer or employee prior to the final disposition of the proceeding if the director, officer or employee furnishes to Olin an undertaking to repay the amount of the expenses advanced in the event it is ultimately determined that he or she is not entitled to indemnification under the Olin Bylaws. The Olin Bylaws do not require that the director, officer or employee furnish any security for such undertaking and provide that such undertaking shall be accepted without reference to the director’s, officer’s or employee’s ability to make repayment. Olin may refrain from, or suspend, payment of expenses if the Olin Board or Virginia legal counsel determines that the director, officer or employee has not met the standards of conduct set forth in the Olin Bylaws.

Virginia law permits a corporation to purchase and maintain insurance on behalf of any director or officer against any liability asserted against, and incurred in his or her capacity as, a director or officer, whether or not the corporation would have the power to indemnify the director or officer against this liability under Virginia law. Olin carries insurance on behalf of its directors and officers.

Blue Cube is incorporated in Delaware. Section 145 of the Delaware General Corporation Law permits a corporation to indemnify its directors and officers against expenses (including attorney’s fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by them in connection with any action, suit or proceeding brought by third parties, if such directors or officers acted in good faith and in a manner they 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 their conduct was unlawful. In a derivative action, i.e., one by or in the right of the corporation, indemnification may be made only for expenses actually and reasonably incurred by directors and officers in connection with the defense or settlement of an action or suit, and only with respect to a matter as to which they shall have acted in good faith and in a manner they reasonably believed to be in or not opposed to the best interests of the corporation, except that no indemnification shall be made if such person shall have been adjudged liable for negligence or misconduct in the performance of his respective duties to the corporation, although the court in which the action or suit was brought may determine upon application that the defendant officers or directors are fairly and reasonably entitled to indemnity for such expenses despite such adjudication of liability.

Section 102(b)(7) of the Delaware General Corporation Law provides that a corporation may eliminate or limit the personal liability of a director to the corporation or its shareholders for monetary damages for breach of

fiduciary duty as a director, provided that such provisions shall not eliminate or limit the liability of a director (1) for any breach of the director’s duty of loyalty to the corporation or its shareholders, (2) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (3) under section 174 of the Delaware General Corporation Law or (4) for any transaction from which the director derived an improper personal benefit. No such provision shall eliminate or limit the liability of a director for any act or omission occurring before the date when such provision becomes effective. The limitations described above do not affect the ability of Blue Cube or its shareholders to seek non-monetary based remedies, such as an injunction or rescission, against a director for breach of his fiduciary duty nor would such limitations limit liability under the federal securities laws.

The Bylaws of Blue Cube require indemnification of directors and officers to the full extent permitted by the Delaware General Corporation Law, as the same may be amended or modified from time to time.

(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, as amended (the “Securities Act”); (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 Securities and Exchange Commission (the “SEC”) 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); and (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.

(2) That, for the purpose of determining any liability under the Securities Act, 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 purposes of determining any liability under the Securities Act, each filing of each of the registrant’s respective annual reports pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934, as amended (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934, as amended) that is incorporated by reference in this 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.

(5) If either registrant is subject to Rule 430C, each prospectus filed pursuant to Rule 424(b) as part of a registration statement relating to an offering, other than registration statements relying on Rule 430B or

(6) That for the purpose of determining liability of the registrants under the Securities Act to any purchaser in the initial distribution of the securities, in a primary offering of securities of the undersigned registrants 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 registrants will be sellers 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 registrants 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 registrants or used or referred to by the undersigned registrants; (iii) The portion of any other free writing prospectus relating the offering containing material information about the undersigned registrants or their securities provided by or on behalf of the undersigned registrants; and (iv) Any other communication that is an offer in the offering made by the undersigned registrants to the purchaser.

This includes information contained in documents filed subsequent to the effective date of the registration statement through the date of responding to the request.

(8) To supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in this registration statement when it became effective.

(9) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of either of the registrants pursuant to the foregoing provisions, or otherwise, the registrants have been advised that in the opinion of the SEC 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 registrants of expenses incurred or paid by a director, officer or controlling person of either of the registrants 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, such registrant will, unless in the opinion of such registrant’s 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 Securities Act of 1933 and will be governed by the final adjudication of such issue.

Pursuant to the requirements of the Securities Act of 1933, the registrant has duly caused this registration statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Clayton, in the state of Missouri on July 29, 2016.
