Western Digital Corporation

$2,300,000,000 4.750% Senior Notes due 2026

Issue Price 100%

Interest payable February 15 and August 15, beginning on August 15, 2018.

We are offering $2,300,000,000 aggregate principal amount of 4.750% Senior Notes due 2026 (the “notes”). The notes will mature on February 15, 2026. Interest will accrue on the notes from February 13, 2018 and the first interest payment date will be August 15, 2018. We intend to use the net proceeds of the offering, together with available cash on hand, to fund the purchase of all of our currently outstanding 10.500% senior unsecured notes due 2024 (the “2024 Unsecured Notes)” in the 2024 Tender Offer (as defined herein) and, if the 2024 Tender Offer is not consummated or if we purchase less than all of the outstanding 2024 Unsecured Notes in the 2024 Tender Offer, to fund the redemption of any 2024 Unsecured Notes that remain outstanding, in each case, including all accrued interest, related premiums, fees and expenses, although we have no legal obligation to do so and the selection of any particular redemption date is in our discretion. See “Use of Proceeds.”

The notes will be redeemable at our option, in whole or in part, at any time and from time to time at the applicable redemption prices specified under “Description of Notes—Optional Redemption” plus accrued and unpaid interest, if any, to, but excluding, the redemption date.

If we experience certain change of control triggering events, we may be required to offer to purchase the notes at 101% of their aggregate principal amount plus accrued and unpaid interest, if any, to the date of purchase.

Initially, the notes will be guaranteed, jointly and severally, on a senior basis by certain of our subsidiaries that are guarantors under our senior credit facilities. Under certain circumstances, subsidiary guarantors may be released from their guarantees without the consent of the holders of the notes.

The notes and the related guarantees will be our senior obligations, will rank equally in right of payment with all of our present and future senior indebtedness and will rank senior in right of payment to all of our present and future subordinated indebtedness. The notes and related guarantees will be effectively subordinated to all of our present and future secured indebtedness (to the extent of the value of the assets securing such indebtedness), including any obligations under our 7.375% senior secured notes due 2023 (the “2023 Secured Notes”) that remain outstanding after giving effect to the Refinancing Transactions (as defined herein) and the Credit Facilities (as defined herein). The notes will be structurally subordinated to all present and future indebtedness and all other liabilities of our subsidiaries that do not guarantee the notes.

We have not applied, and do not intend to apply, for the listing of the notes on any exchange or automated dealer quotation system. Currently, there is no public market for the notes.

Investing in the notes involves risks. See “Risk Factors” beginning on page 16 of this prospectus.

We expect to deliver the notes to purchasers on or about February 13, 2018, only in book-entry form through the facilities of The Depository Trust Company.

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or determined if this prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

Certain statements in this prospectus and the documents incorporated herein by reference contain “forward-looking” statements within the meaning of the federal securities laws. Any statements that do not relate to historical or current facts or matters are forward-looking statements. You can identify some of the forward-looking statements by the use of forward-looking words, such as “may,” “will,” “could,” “would,” “project,” “believe,” “anticipate,” “expect,” “estimate,” “continue,” “potential,” “plan,” “forecast,” and the like, or the use of future tense. Statements concerning current conditions may also be forward-looking if they imply a continuation of current conditions. Examples of forward-looking statements include, but are not limited to, statements concerning:

Forward-looking statements are subject to risks and uncertainties that could cause actual results to differ materially from those expressed in the forward-looking statements. You are urged to carefully review the

14

disclosures we make concerning risks and other factors that may affect our business and operating results, including those described below under the heading “Risk Factors” as well as those made in documents incorporated by reference in this prospectus, including those set forth in our Quarterly Report on Form 10-Q for the quarter ended September 29, 2017, as such risk factors may be amended, supplemented or superseded from time to time by other reports we file with the Securities and Exchange Commission (“SEC”) in the future, including subsequent Annual Reports on Form 10-K and Quarterly Reports on Form 10-Q. We caution you that any forward-looking statements made in this prospectus and the documents incorporated herein by reference are not guarantees of future performance, events or results, and you should not place undue reliance on these forward-looking statements, which speak only as of their respective dates. We do not intend, and undertake no obligation, to publish revised forward-looking statements to reflect future events or circumstances or to reflect the occurrence of unanticipated events.

NON-GAAP FINANCIAL MEASURES

In addition to financial information presented in accordance with generally accepted accounting principles in the United States (“GAAP”), we use certain “non-GAAP financial measures” to evaluate the operating and financial performance of our business, identify trends affecting our business, develop projections and make strategic business decisions. Generally, a non-GAAP financial measure is a numerical measure of a company’s operating performance, financial position or cash flow that includes or excludes amounts that are included or excluded from the most directly comparable measure calculated and presented in accordance with GAAP.

Our non-GAAP financial measures may not provide information that is directly comparable to similarly titled measures provided by other companies in their industry, as other companies in their industry may calculate non-GAAP financial results differently, limiting the usefulness of those measures for comparative purposes. In addition, there are limitations in using non-GAAP financial measures as analytical tools because they are not prepared in accordance with GAAP, may be different from non-GAAP financial measures used by other companies and exclude expenses and other items that may have a material impact on reported financial results. The presentation of non-GAAP financial information is not meant to be considered in isolation or as a substitute for the directly comparable financial measures prepared in accordance with GAAP. We urge you to review the reconciliations of the non-GAAP financial measures to the comparable GAAP financial measures included herein, and not to rely on any single financial measure to evaluate our business.

EBITDA represents net income plus interest and other expense, net; income tax expense (benefit); and depreciation and amortization. Adjusted EBITDA represents EBITDA plus aggregate contractual adjustments provided for in our debt instruments. Adjusted net debt represents total debt minus cash and cash equivalents and short-term investments. We include information concerning EBITDA, Adjusted EBITDA and Adjusted net debt because we believe they are useful measures to evaluate our operating performance and financial position. As measures of our operating performance, we believe EBITDA, Adjusted EBITDA and Adjusted net debt provide a measure of operating results unaffected by differences in capital structures, capital investment cycles and ages of related assets among otherwise comparable companies. EBITDA and Adjusted EBITDA do not represent net income or operating income, and Adjusted net debt does not represent total debt, as defined by GAAP and they should not be considered in isolation or as alternatives to those measures in evaluating operating performance. See “Prospectus Summary—Historical Consolidated Financial Data” for a reconciliation of EBITDA, Adjusted EBITDA and Adjusted net debt to the directly comparable GAAP measures.

RISK FACTORS

An investment in the notes involves risks. Before making an investment decision, you should carefully consider, among other factors, the risks described below that are specific to the notes, and those that could affect us and our business described in our Quarterly Report on Form 10-Q for the quarter ended September 29, 2017, which is incorporated by reference in this prospectus, as well as the other information we include or incorporate by reference in this prospectus. See “Where You Can Find More Information and Incorporation of Certain Documents by Reference.”

The incurrence of substantial indebtedness in connection with the financing of the Merger may have an adverse impact on our liquidity, limit our flexibility in responding to other business opportunities and increase our vulnerability to adverse economic and industry conditions.

In connection with the Merger, we substantially increased our indebtedness, which could adversely affect our ability to fulfill our obligations and have a negative impact on our financing options and liquidity position. On April 13, 2016, we issued $1,875.0 million in aggregate principal amount of the 2023 Secured Notes and $3,350.0 million in aggregate principal amount of the 2024 Unsecured Notes. We also entered into new senior credit facilities on April 29, 2016 (the “Credit Facilities”) under which we had $8.1 billion aggregate principal amount outstanding as of September 29, 2017. As of September 29, 2017, we had $13.3 billion aggregate principal amount of total indebtedness, or $11.3 billion aggregate principal amount on an as adjusted basis as described under “Capitalization.” We had $1.0 billion of additional borrowing availability under our Revolving Credit Facility, which includes a $200.0 million sublimit for letters of credit, as of September 29, 2017, and, on an as adjusted basis after giving effect to the RCF Increase, additional borrowing availability under the Revolving Credit Facility would have been $1.5 billion. The proceeds from the issuance of the 2023 Secured Notes, 2024 Unsecured Notes and new credit facilities were used to pay part of the purchase price for the Merger, refinance existing indebtedness of Western Digital and SanDisk and pay related transaction-related fees and expenses.

Our high debt balances could have significant consequences, which include, but are not limited to, the following:

In addition, our credit ratings impact the cost and availability of future borrowings and, accordingly, our cost of capital. Our ratings reflect the opinions of the ratings agencies of our financial strength, operating

16

performance and ability to meet our debt obligations. There can be no assurance that we will achieve a particular rating or maintain a particular rating in the future.

Because of high debt balances, we may not be able to service our debt obligations in accordance with their terms.

As of September 29, 2017, we had $13.3 billion aggregate principal amount of total indebtedness, or $11.3 billion aggregate principal amount on an as adjusted basis as described under “Capitalization.” We had $1.0 billion of additional borrowing availability under the Revolving Credit Facility as of September 29, 2017 and, on an as adjusted basis after giving effect to the RCF Increase, additional borrowing availability under the Revolving Credit Facility would have been $1.5 billion. Our ability to meet our expense and debt service obligations contained in our debt agreements will depend on our available cash and our future performance, which will be affected by financial, business, economic and other factors, including potential changes in laws or regulations, industry conditions, industry supply and demand balance, customer preferences, the success of our products and pressure from competitors. If we are unable to meet our debt service obligations or should we fail to comply with our financial and other restrictive covenants contained in the agreements governing our indebtedness, we may be required to refinance all or part of our debt, sell important strategic assets at unfavorable prices, incur additional indebtedness or issue common stock or other equity securities. We may not be able to, at any given time, refinance our debt, sell assets, incur additional indebtedness or issue equity securities on terms acceptable to us, in amounts sufficient to meet our needs or at all. Our inability to service our debt obligations or refinance our debt could have a material adverse effect on our business, operating results and financial condition. In addition, our debt obligations may limit our ability to make required investments in capacity, technology or other areas of our business, which could have a material adverse effect on our business, operating results and financial condition. Further, if we are unable to repay, refinance or restructure our secured indebtedness, the holder of such debt could proceed against the collateral securing that indebtedness.

The terms of the agreements governing our indebtedness may restrict our current and future operations, particularly our ability to respond to changes or to pursue our business strategies, and could adversely affect our capital resources, financial condition and liquidity.

Although the restrictive covenants in the notes offered hereby will be more limited and we are seeking a concurrent amendment to the Credit Facilities to increase covenant flexibility upon meeting certain conditions, the agreements that govern our existing indebtedness (unless we meet certain conditions that would limit the scope of the restrictive covenants in the Credit Facilities) contain a number of restrictive covenants that impose significant operating and financial restrictions on us and may limit our ability to engage in acts that may be in our long-term best interests, including, among other things, restrictions on our ability to:

17

Due to these restrictions, we may be unable to raise additional debt or equity financing to operate our business during general economic or business downturns, and we may be unable to compete effectively or take advantage of new opportunities to grow our business. In addition, our credit facilities require us to comply with certain financial maintenance covenants. Our ability to satisfy these financial maintenance covenants can be affected by events beyond our control, and we cannot assure you that we will meet them. The indebtedness and these restrictive covenants may have the effect, among other things, of limiting our flexibility in the conduct of our business and making us more vulnerable to economic downturns and adverse competitive and industry conditions.

A breach of the covenants under these agreements could result in an event of default under the applicable indebtedness, which, if not cured or waived, could result in us having to repay our borrowings (including under the Credit Facilities) or repay any 2023 Secured Notes that remain outstanding and the notes before their due dates. Such default may allow the debt holders to accelerate the related debt and may result in the acceleration of any other debt, leases, or other obligations to which a cross-acceleration or cross-default provision applies. If we are forced to refinance these borrowings, any 2023 Secured Notes that remain outstanding or the notes on less favorable terms or if we were to experience difficulty in refinancing the debt prior to maturity, our results of operations and financial condition could be materially affected. In addition, an event of default under our credit facilities may permit the lenders under our credit facilities to terminate all commitments to extend further credit under such credit facilities. If we are unable to repay the amounts due and payable under our credit facilities and any 2023 Secured Notes that remain outstanding, those lenders may be able to proceed against the collateral granted to them to secure that indebtedness. In the event our lenders or holders of notes accelerate the repayment of such borrowings, we cannot assure you that we will have sufficient assets to repay such indebtedness. Any of the foregoing would have a material adverse effect on our business, results of operations and financial condition.

We, including our subsidiaries, have the ability to incur substantially more indebtedness, including senior secured indebtedness, which could further increase the risks associated with our leverage.

Subject to the restrictions in the Credit Facilities and the indentures governing any 2023 Secured Notes that remain outstanding and the notes, we, including our subsidiaries, have the ability to incur significant additional indebtedness. As of September 29, 2017, after giving effect to this offering and the use of proceeds, together with available cash on hand, to repurchase or redeem the 2024 Unsecured Notes we had:

Although the terms of the Credit Facilities and the indenture governing the 2023 Secured Notes include restrictions on the incurrence of additional indebtedness, these restrictions are subject to a number of important exceptions, and indebtedness incurred in compliance with these restrictions could be substantial. The terms of the indenture governing the notes generally will not restrict us from incurring additional indebtedness, although it will place some limitations on our ability and the ability of our subsidiaries to create liens securing indebtedness. If we incur significant additional indebtedness, the related risks that we face could increase.

18

The notes will be our senior unsecured obligations, and the related guarantees will be unsecured obligations of the guarantors. As such, the notes and the related guarantees will be effectively subordinated to any of our or our guarantors’ secured debt, including our existing and any future debt under the Credit Facilities and any 2023 Secured Notes that remain outstanding.

Our obligations under the notes and the guarantors’ obligations under the guarantees will not be secured. The notes will be effectively subordinated to our and our guarantors’ existing and any future secured indebtedness, including the Credit Facilities and any 2023 Secured Notes that remain outstanding, to the extent of the value of the assets securing such indebtedness, which assets include substantially all of our assets and the assets of our subsidiary guarantors.

As of September 29, 2017, we and our guarantors had approximately $9.9 billion aggregate principal amount of secured indebtedness outstanding and on an as adjusted basis after giving effect to the settlement of the Euro TLB Prepayment on November 17, 2017, we had approximately $8.9 billion aggregate principal amount of secured debt outstanding. We had $1.0 billion of additional borrowing availability under the Revolving Credit Facility as of September 29, 2017 and, on an as adjusted basis after giving effect to the RCF Increase, additional borrowing availability under the Revolving Credit Facility would have been $1.5 billion. If we are involved in any dissolution, liquidation or reorganization, or if we default under the indenture governing the notes, holders of our secured debt would be paid before holders of the notes receive any amounts due under the notes to the extent of the value of the collateral securing such indebtedness. In that event, holders of the notes may not be able to recover any or all of the principal or interest due under the notes.

In the event that we are declared bankrupt, become insolvent or are liquidated or reorganized or if we default under the Credit Facilities or any 2023 Secured Notes that remain outstanding, the lenders or the holders of any 2023 Secured Notes that remain outstanding could foreclose on the pledged assets to the exclusion of holders of the notes, even if an event of default exists under the indenture governing the notes at such time. Furthermore, if the lenders or the holders of any 2023 Secured Notes that remain outstanding foreclose upon and sell the pledged equity interests in any guarantor of the notes, then that guarantor will be released from its guarantee of the notes automatically and immediately upon such sale. In any such event, because the notes will not be secured by any of our assets or the equity interests in the guarantors, it is possible that there would be no assets remaining from which your claims could be satisfied or, if any assets remained, they might be insufficient to satisfy your claims in full.

The notes will be structurally subordinated to all indebtedness of our existing subsidiaries that are not guarantors of the notes and our future subsidiaries that do not become guarantors of the notes.

The notes will not be guaranteed by any of our existing or future non-U.S. subsidiaries, any of our less than 100% owned U.S. subsidiaries or any other U.S. subsidiaries that do not guarantee the Credit Facilities. Accordingly, claims of holders of the notes will be structurally subordinated to the claims of creditors of these non-guarantor subsidiaries, including trade creditors. All obligations of our non-guarantor subsidiaries will have to be satisfied before any of the assets of such subsidiaries would be available for distribution, upon a liquidation or otherwise, to us or a guarantor of the notes. As of September 29, 2017, our non-guarantor subsidiaries had $3.4 billion of aggregate total balance sheet liabilities (excluding intercompany transactions), including $30 million of long-term debt, all of which would have been structurally senior to the notes and the related guarantees.

In addition, the indenture governing the notes will, subject to some limitations, permit these non-guarantor subsidiaries to incur additional indebtedness and will not include any limitation on the amount of other liabilities, such as trade payables, that may be incurred by these subsidiaries.

The lenders under the Credit Facilities will have the discretion to release guarantors under these facilities in a variety of circumstances and under certain circumstances may be automatically released, which will cause those guarantors to be released from their guarantees of the notes.

So long as any obligations under our Credit Facilities remain outstanding, any guarantee of the notes may be released without action by, or consent of, any holder of notes or the trustee under the indenture governing

19

the notes if, at the discretion of lenders under the Credit Facilities, the related guarantor is no longer a guarantor of obligations under the Credit Facilities. The lenders under the Credit Facilities will have the discretion to release the guarantees under these facilities in a variety of circumstances. In addition, in connection with the TLA increase or thereafter, we may have the flexibility to automatically release all of the collateral and guarantees securing the Credit Facilities upon the prepayment or other termination of the outstanding term B loans under the Credit Facilities as well as other secured or subsidiary debt in excess of certain thresholds, subject to certain other conditions to be agreed. Any of our subsidiaries that are released as guarantors of the Credit Facilities will automatically be released as guarantors of the notes. You will not have a claim as a creditor against any subsidiary that is no longer a guarantor of the notes, and the indebtedness and other liabilities, including trade payables, whether secured or unsecured, of those subsidiaries will effectively be senior to your claims as a holder of the notes.

Under certain circumstances a court could cancel the notes or the related guarantees under fraudulent conveyance laws. 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 incurrence of the guarantees. Under federal bankruptcy law and comparable provisions of state fraudulent transfer or conveyance laws, which may vary from state to state, the notes or guarantees could be voided as a fraudulent transfer or conveyance if we or any of the guarantors, as applicable: (1) issued the notes or incurred the guarantees with the intent of hindering, delaying or defrauding creditors or (2) 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 (2) only, one of the following is also true at the time thereof:

If a court were to find that the issuance of the notes or the incurrence of the guarantees was a fraudulent transfer or conveyance, the court could void the payment obligations under the notes or such guarantee or subordinate the notes or such guarantee to presently existing and future indebtedness of ours or of the related guarantor, or require the holders of the notes to repay any amounts received with respect to such guarantee. In the event of a finding that a fraudulent transfer or conveyance occurred, you may not receive any repayment on the notes. Further, the voidance 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 such debt.

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 an antecedent debt is secured or satisfied. A debtor will generally not be considered to have received value in connection with a debt offering if the debtor uses the proceeds of that offering to make a dividend payment or otherwise retire or redeem equity securities issued by the debtor. We cannot be certain as to the standards a court would use to determine whether or not we or the guarantors were solvent at the relevant time or, regardless of the standard that a court uses, that the issuance of the notes and the guarantees would not be subordinated to our or any of our guarantors’ other debt.

Generally, an entity would be considered insolvent if, at the time it incurred debt:

20

If the guarantees were legally challenged, any guarantee could also be subject to the claim that, since the guarantee was incurred for our benefit, and only indirectly for the benefit of the guarantor, the obligations of the applicable guarantor were incurred for less than fair consideration. A court could thus void the obligations under the guarantees, subordinate them to the applicable guarantor’s other debt or take other action detrimental to the holders of the notes.

The indenture governing the notes includes a “savings clause” intended to limit each guarantor’s liability under its guarantee to the maximum amount that it could incur without causing the guarantee to be a fraudulent transfer under applicable law. There can be no assurance that this provision will be upheld as intended. In a 2009 case, the U.S. Bankruptcy Court in the Southern District of Florida found this kind of provision in that case to be ineffective, and held the guarantees to be fraudulent transfers and voided them in their entirety. The United States Court of Appeals for the Eleventh Circuit subsequently affirmed the liability findings of the bankruptcy court without ruling directly on the enforceability of savings clauses generally. If the decision of the bankruptcy court were followed by other courts, the risk that the guarantees would be deemed fraudulent conveyances would be significantly increased.

Repayment of our indebtedness, including the notes, is dependent on cash flow generated by our subsidiaries.

Our subsidiaries own a substantial portion of our assets and conduct a substantial portion of our operations. Accordingly, repayment of our indebtedness, including the notes, is dependent, to a significant extent, on the generation of cash flow by our subsidiaries and their ability to make such cash available to us, by dividend, debt repayment or otherwise. Unless they are guarantors of the notes, our subsidiaries do not have any obligation to pay amounts due on the notes or to make funds available for that purpose. Certain of our subsidiaries may not be able to, or may not be permitted to, make distributions to enable us to make payments in respect of our indebtedness, including the notes. Each subsidiary is a distinct legal entity and, under certain circumstances, legal and contractual restrictions may limit our ability to obtain cash from our subsidiaries. While the indenture governing the notes limits the ability of our restricted subsidiaries to incur consensual restrictions on their ability to pay dividends or make other intercompany payments to us, these limitations are subject to certain qualifications and exceptions. In the event that we do not receive distributions from our subsidiaries, we may be unable to make required principal and interest payments on our indebtedness, including the notes.

There is no established trading market for the notes, and you may not be able to sell the notes readily or at all or at or above the price that you paid.

The notes are a new issue of securities and there is no established trading market for them. We do not intend to apply for the notes to be listed on any securities exchange or to arrange for quotation on any automated dealer quotation system. The underwriters have advised us that they intend to make a market in the notes, but they are not obligated to do so and may discontinue any market making in the notes at any time, in their sole discretion. You may not be able to sell the notes at a particular time or at favorable prices. As a result, we cannot assure you as to the liquidity of any trading market for the notes. Accordingly, you may be required to bear the financial risk of your investment in the notes indefinitely. If a trading market were to develop, future trading prices of the notes may be volatile and will depend on many factors, including:

21

In addition, the market for non-investment grade debt historically has been subject to disruptions that have caused substantial volatility in the prices of securities similar to the notes. The market for the notes, if any, may be subject to similar disruptions that could adversely affect their value.

We may not have the ability to raise the funds necessary to finance the change of control offer required by the indenture governing the notes.

Upon the occurrence of a “Change of Control Triggering Event,” as defined in the indenture governing the notes, we must offer to buy back the notes at a price equal to 101% of the principal amount, together with any accrued and unpaid interest, if any, to the date of the repurchase. Our failure to purchase, or give notice of purchase of, the notes would be a default under the indenture governing the notes. See “Description of the Notes—Change of Control Triggering Event”.

Furthermore, certain change of control triggering events would also constitute an event of default under the Credit Facilities. Upon the occurrence of a change of control, the lenders under the Credit Facilities may have the right, among other things, to terminate their lending commitments or to cause all outstanding debt obligations under the Credit Facilities to become due and payable and proceed against the assets securing such debt, any of which actions would prevent us from borrowing under the Credit Facilities to finance a repurchase of the notes. We cannot assure you that we will have available funds sufficient to repurchase the notes and satisfy other payment obligations that could be triggered upon the change of control. If we do not have sufficient financial resources to effect a change of control offer, we would be required to seek additional financing from outside sources to repurchase the notes. We cannot assure you that financing would be available to us on satisfactory terms, or at all.

The definition of change of control in the indenture governing the notes includes a phrase relating to the conveyance, transfer or lease of “all or substantially all” of our and our subsidiaries’ properties and assets, 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, in certain circumstances there may be a degree of uncertainty as to whether a particular transaction would involve a disposition of “all or substantially all” of the property or assets of a person. As a result, it may be unclear as to whether a change of control has occurred and whether a holder of notes may require us to make an offer to repurchase the notes as described above.

The trading prices for the notes will be directly affected by many factors, including our credit rating.

Credit rating agencies continually revise their ratings for companies they follow, including us. Any ratings downgrade could adversely affect the trading price of the notes, or the trading market for the notes, to the extent a trading market for the notes develops. The condition of the financial and credit markets and prevailing interest rates have fluctuated in the past and are likely to fluctuate in the future and any fluctuation may impact the trading prices of the notes.

The indenture governing the notes will contain negative covenants that may have a limited effect.

The indenture that will govern the notes will contain limited covenants that restrict our ability and the ability of our restricted subsidiaries to incur liens on our assets and enter into certain mergers with or into, or sell substantially all of our assets to, another person. These limited covenants contain exceptions that will allow us and our subsidiaries to incur liens with respect to material assets. See “Description of Notes—Certain Covenants.” In light of these exceptions, holders of the notes may be effectively subordinated to new lenders to the extent of the value of the collateral pledged to secure obligations owed to such lenders.

22

Changes in our credit rating may adversely affect your investment in the notes.

Our credit rating, any rating that may be assigned to the notes, and the credit ratings assigned to our outstanding debt, reflect the rating agencies’ assessments of our ability to make payments on our debt when due. Actual or anticipated changes or downgrades in our credit ratings or those of the notes if issued, including any announcement that our ratings are under further review for a downgrade, with respect to the issuance of the notes or our other outstanding debt could increase our corporate borrowing costs and affect the market value of your notes. Also, our credit ratings may not reflect the potential impact of risks related to structure, market or other factors related to the value of the notes.

A rating is not a recommendation to buy, sell or hold the notes, and there is no assurance that any rating will apply for any given period of time or that a rating may not be adjusted or withdrawn. We cannot be sure that rating agencies will rate the notes or maintain their ratings once issued. Neither we nor any underwriter undertakes any obligation to obtain a rating, maintain the ratings once issued or to advise holders of the notes of any change in rating.

We rely substantially on our business ventures with Toshiba’s wholly owned subsidiary, Toshiba Memory Corporation (“TMC”), for the supply of NAND-flash memory and the development of NAND-flash technology, which subjects us to risks and uncertainties that could harm our business, financial condition and operating results.

We are dependent on our ventures with Toshiba’s wholly owned subsidiary, TMC, to develop and manufacture NAND-flash memory products for our NAND-flash memory supply, and therefore our business, financial condition and operating results, and our ability to realize the anticipated benefits from the Merger, is dependent on the continued success of Flash Ventures.

The majority of our NAND-flash memory is supplied by Flash Ventures, which limits our ability to respond to market demand and supply changes. A failure to accurately forecast demand could cause us to over-invest or under-invest in technology transitions or the expansion of captive memory capacity in Flash Ventures. Over-investment could result in excess supply, which could cause significant decreases in our product prices, significant excess, obsolete or lower of cost or net realizable value inventory write-downs or under-utilization charges, and the potential impairment of our investments in Flash Ventures. On the other hand, if we or TMC under-invest in captive memory capacity or technology transitions, if we grow capacity more slowly than the rest of the industry, if our technology transitions do not occur on the timeline that we expect, if we encounter unanticipated difficulties in implementing these transitions, or if we implement technology transitions more slowly than our competitors, we may not have enough captive supply of the right type of memory or at all to meet demand on a timely and cost effective basis and we may lose opportunities for revenue, gross margin and share as a result. If our NAND memory supply is limited, we may make strategic decisions with respect to the allocation of our supply among our products and customers, and these strategic allocation decisions may result in less favorable gross margin in the short term or damage certain customer relationships. Growth of our NAND-flash memory bit supply at a slower rate than the overall industry for an extended period of time would result in lowering our share which could limit our future opportunities and harm our financial results. We are also contractually obligated to pay for 50% of the fixed costs of Flash Ventures regardless of whether we purchase any wafers from Flash Ventures. Furthermore, purchase orders placed with Flash Ventures and under the foundry arrangements with TMC for up to three months are binding and cannot be canceled. Therefore, once our purchase decisions have been made, our production costs for flash memory are fixed, and we may be unable to reduce costs to match any subsequent declines in pricing or demand, which would harm our gross margin. Our limited ability to react to fluctuations in flash memory supply and demand makes our financial results particularly susceptible to variations from our forecasts and expectations.

In addition, we partner with TMC on the development of NAND-flash technology, including the next technology transitions of NAND-flash, as well as other non-volatile memory technology in support of Flash Ventures.

23

These ventures are subject to various risks that could harm the value of our investments, our revenue and costs, our future rate of spending, our technology plans and our future growth opportunities. Under the terms of our venture agreements with TMC, which govern the operations of Flash Ventures, we have limited power to unilaterally direct most of the activities that most significantly impact Flash Ventures’ performance and we have limits to our ability to source or fabricate NAND-flash products outside of the Flash Ventures. The integration of SanDisk into our organization could complicate the process of reaching agreement with TMC in a timely and favorable manner. We may not always agree with TMC on our joint research and development roadmap or expansions or conversions of production capacity. In addition, Toshiba’s financial position or TMC’s shift in strategic priorities could adversely impact our business.

In March 2017, Toshiba announced significant losses related to its U.S. nuclear business and, in connection with its fiscal year 2016 financial statements, Toshiba advised that there were material events and conditions that raise substantial doubt about its ability to continue as a going concern. Subsequently, in September 2017, Toshiba announced it had entered into a definitive agreement to sell TMC, including its interests in Flash Ventures, to a consortium led by SK Hynix Inc. and Bain Capital (the “Bain Consortium”) that includes other competitors, as well as key customers. In December 2017, in connection with a global settlement agreement with Toshiba and TMC, we consented to the transfer of Toshiba’s interests in Flash Ventures to TMC and the sale of TMC to the Bain Consortium. If the Bain Consortium or another third party acquires any of Toshiba’s interests in Flash Ventures, it could lead to delays in decision-making, disputes, or changes in strategic direction that could adversely impact Flash Ventures and/or adversely affect our business prospects, results of operations and financial condition. The purchaser might not have the same interest that we do in protecting and growing Flash Ventures’ business and might have conflicts of interest between itself and Flash Ventures or us. To the extent Toshiba retains its interests in TMC, a failure by Toshiba to stabilize its financial condition could cause TMC to become unable to, or otherwise fail to, timely fund investments in Flash Ventures or our joint development efforts or fulfill its payment obligations to suppliers, which could harm Flash Ventures’ operations, our joint technology roadmap and supplier relationships. Reduced investment in manufacturing capacity or research and development, or other misalignment between us and Toshiba, TMC or a third party acquirer of TMC on strategic direction, could impact Flash Ventures’ ability to stay at the forefront of technological advancement and/or our investment in Flash Ventures. Flash Ventures’ competitiveness and/or our investment in Flash Ventures could also be harmed by a mishandling or misuse of IP or other competitively sensitive confidential information regarding Flash Ventures, such as its technology roadmap, business or investment plans, by a third party that might gain access to such information.

Flash Ventures requires significant investments by both TMC and us for technology transitions, including the transition to 3D NAND, and capacity expansions. Lease financings guaranteed by or on behalf of both TMC and us are not currently available to Flash Ventures on favorable terms and we are pursuing alternative forms of financing to fund our share of investments, which might not continue to be accessible. To the extent that lease financings for Flash Ventures are not available on favorable terms or at all, more cash would be required to fund investments. If TMC does not or we do not provide sufficient resources, or have adequate access to credit, to timely fund investments in Flash Ventures, our investments could be delayed or reduced.

As announced by Toshiba, TMC plans to construct a new wafer fabrication facility in Iwate, Japan, to provide additional cleanroom space for the manufacture of 3D NAND, with site preparation scheduled to begin in February 2018. Although we intend to enter into agreements with TMC in due course to participate in the new Iwate facility, there is no certainty as to when, and on what terms, we will do so. If we are unable to extend our partnership with TMC to the Iwate facility on favorable terms, our future supply of captive NAND-flash memory could be adversely impacted, which could adversely affect our long-term business and financial results.

We are monitoring and evaluating other potential impacts of Toshiba’s planned sale of TMC and financial condition on Flash Ventures and, in turn, on our own memory business and financial condition. These factors could adversely affect the value of our investments in Flash Ventures and our business prospects, results of operations and financial condition.

24

If we are unable to successfully integrate the systems and operations of HGST, our business and financial condition may be adversely affected.

In connection with obtaining the regulatory approvals required to complete the acquisition of HGST, we agreed to certain conditions required by MOFCOM, including adopting measures to keep HGST as an independent competitor until MOFCOM agreed otherwise. In October 2015, MOFCOM announced that it had made a decision allowing us to integrate substantial portions of our HGST and WD subsidiaries, provided that we were obligated to continue offering both HGST and WD product brands and maintaining separate sales teams to separately offer products under the WD and HGST brands for two years from the date of the decision. As of December 29, 2017, the integration of the substantial portions of our HGST and WD subsidiaries that we were permitted to integrate as a result of MOFCOM’s 2015 decision (including corporate functions, research and development, recording heads and magnetic media operations, engineering and manufacturing), were largely completed. However, certain financial and operational systems have not yet been integrated. The MOFCOM restrictions related to our HGST and WD product brands and sales teams expired in October 2017, which enabled us to begin integrating our sales teams and brands. While we combine our HGST and WD product brands and sales teams and integrate certain financial and operating systems, we will continue to incur additional costs. These additional costs, along with any delay in the integration process or higher than expected integration costs or other integration issues, could adversely affect our business and financial condition.

Changes in tax laws could increase our worldwide tax rate and materially affect our financial position and results of operations.

On December 22, 2017, the President of the United States of America signed the Tax Cuts and Jobs Act (the “2017 Act”), which includes a broad range of tax reform proposals affecting businesses, including a reduction in the U.S. federal corporate tax rate from 35% to 21%, a one-time mandatory deemed repatriation tax on earnings of certain foreign subsidiaries that were previously tax deferred, and a new minimum tax on certain foreign earnings. The 2017 Act significantly impacts our effective tax rate for fiscal year 2018 as a result of the deemed repatriation tax, and may impact several other elements of our operating model. In future years, certain additional provisions of the 2017 Act, such as a minimum tax on foreign earnings, will also apply to the Company and, as a result, the Company generally expects its effective tax rate to increase from the rate expected for fiscal year 2018 (excluding the mandatory deemed repatriation tax and the re-measurement of deferred taxes). Taxes due over a period of time as a result of the new tax law could be accelerated upon certain triggering events, including failure to pay such taxes when due. The new law makes broad and complex changes to the US tax code and we expect to see future regulatory, administrative or legislative guidance. We are analyzing the 2017 Act to determine the full impact of the new tax law, and to the extent any future guidance differs from our preliminary interpretation of the law, it could have a material effect on our financial position and results of operations.

In addition, many countries in the European Union and around the globe have adopted and/or proposed changes to current tax laws. Further, organizations such as the Organization for Economic Cooperation and Development, have published action plans that, if adopted by countries where we do business, could increase our tax obligations in these countries. Due to the large scale of our U.S. and international business activities, many of these enacted and proposed changes to the taxation of our activities could increase our worldwide effective tax rate and harm our financial position and results of operations.

USE OF PROCEEDS

We estimate that we will receive net proceeds of approximately $2.28 billion from the offering, after deducting the underwriters’ discounts and commissions and estimated offering expenses payable by us. We intend to use the net proceeds from this offering, together with cash on hand, to fund the purchase of the 2024 Unsecured Notes in the 2024 Tender Offer, and, if the 2024 Tender Offer is not consummated, or if we purchase less than all of the outstanding 2024 Unsecured Notes in the 2024 Tender Offer, to fund the redemption of any 2024 Unsecured Notes that remain outstanding, in each case, including all accrued interest, related premiums, fees and expenses. As of September 29, 2017, the outstanding aggregate principal amount of the 2024 Unsecured Notes was $3,350.0 million, and the 2024 Unsecured Notes mature on April 1, 2024.

Certain of the underwriters and/or their respective affiliates are holders of the 2024 Unsecured Notes and, as a result, will receive a pro rata portion of such net proceeds from this offering used in connection with such repurchase or redemption of the 2024 Unsecured Notes. In addition, Merrill Lynch, Pierce, Fenner & Smith Incorporated and J.P. Morgan Securities LLC are each acting as Dealer-Managers in connection with the 2024 Tender Offer and, as a result, will be receiving customary fees for such roles. See “Underwriting.”

DESCRIPTION OF NOTES

Western Digital Corporation (“Western Digital”) will issue its 4.750% Senior Notes due 2026 (the “Notes”) (the “Notes”) under an indenture to be dated the Issue Date (the “Indenture”) by and among Western Digital, the Guarantors party thereto and U.S. Bank National Association, as trustee (the “Trustee”). The Indenture will be subject to, and governed by, the Trust Indenture Act of 1939, as amended.

Certain terms used in this description are defined under the subheading “—Certain Definitions.” In this description, the words “we,” “us,” “our” and “Issuer” refer to Western Digital and not to any of its subsidiaries.

The following description is only a summary of the material provisions of the Notes and the Indenture. We urge you to read the Indenture because it, not this description, defines your rights as holders of the Notes. You may request copies of the Indenture at our address set forth under the heading “Where You Can Find More Information.”

The registered holder will be treated as the owner of a Note for all purposes. Only registered holders will have rights under the Indenture.

Brief Description of the Notes

The Notes will be:

Principal, Maturity and Interest

We will initially issue up to $2,300 million aggregate principal amount of the Notes in minimum denominations of $2,000 and any greater integral multiple of $1,000. The Notes will mature on February 15, 2026. We are permitted to issue more Notes under the Indenture in an unlimited aggregate principal amount (the “Additional Notes”); provided that any such Additional Notes that are not issued either in a “qualified reopening” for U.S. federal income tax purposes, with no more than a de minimis amount of original issue discount or otherwise as part of the same “issue” for U.S. federal income tax purposes will have one or more separate CUSIP numbers. The Notes and the Additional Notes, if any, will be treated as a single class for all purposes of the Indenture, including waivers, amendments, redemptions and offers to purchase. Unless the context otherwise requires, for all purposes of the Indenture and this “Description of Notes,” references to the Notes include any Additional Notes actually issued.

Interest on the Notes will accrue at the rate of 4.750% per annum and will be payable semiannually in arrears on February 15 and August 15 commencing on August 15, 2018. We will make each interest payment to the holders of record of the Notes on the immediately preceding February 1 and August 1.

30

Interest on the Notes will accrue from the date of original issuance or, if interest has already been paid, from the date it was most recently paid. Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months.

Optional Redemption

Except as set forth below, we will not be entitled to redeem the Notes at our option.

Notice of any redemption of the Notes in connection with a transaction or an event (including a Change of Control Triggering Event) may, at the Issuer’s discretion, be given prior to the completion or the occurrence thereof and any such redemption or notice may, at the Issuer’s discretion, be subject to one or more conditions precedent, including, but not limited to, completion or occurrence of the related transaction or event. In addition, if such redemption is subject to one or more conditions precedent, such notice shall describe each such condition and, if applicable, shall state that in the Issuer’s discretion, the redemption date may be delayed until such time (including, subject to the applicable procedures of DTC, more than 60 days after the date the notice of redemption was mailed or delivered, including by electronic transmission) as any or all such conditions shall be satisfied (or waived by the Issuer in its sole discretion), or such redemption may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied by the redemption date, or by the redemption date as so delayed. The Issuer will provide prompt written notice to the Trustee and the holders of the Notes prior to the close of business two Business Days prior to the redemption date rescinding such redemption and notice of redemption shall be rescinded and of no force or effect. Upon the Company’s written request given at least five (5) Business Days prior to the date such notice shall be sent (unless the Trustee consents to a shorter period), the Trustee shall (on at the date specified in such written request or promptly after such time) forward such notice to the holders in the Company’s name and at the Company’s expense in the same manner in which the notice of redemption was given.

Prior to November 15, 2025, we will be entitled, at our option, to redeem all or a portion of the Notes at a redemption price equal to 100% of the principal amount of the Notes plus the Notes Applicable Premium as of, and accrued and unpaid interest, if any, to, but excluding, the redemption date. In addition, on or after November 15, 2025, we may redeem the Notes in whole or in part at a redemption price equal to 100% of the principal amount thereof, plus accrued and unpaid interest to, but excluding, the redemption date. Notice of any such redemption must be mailed by first-class mail to each holder’s registered address (or delivered by electronic transmission in accordance with the applicable procedures of DTC), not less than 30 nor more than 60 days prior to the redemption date. Calculation of the redemption price will be made by us or on our behalf by such person as we shall designate; provided that such calculation or the correctness thereof shall not be a duty or obligation of the Trustee.

If the optional redemption date is on or after an interest record date but on or prior to the related interest payment date, then any accrued and unpaid interest in respect of Notes subject to redemption will be paid on the redemption date to the Person in whose name the Note is registered at the close of business, on such record date, and no additional interest will be payable to holders whose Notes will be subject to redemption by the Issuer.

“Applicable Premium” means with respect to a Note at any redemption date, as provided by the Issuer, the excess of (1) the present value at such redemption date of the Remaining Scheduled Payments on such Note (but excluding accrued and unpaid interest, if any, to, but excluding, the redemption date), computed using a discount rate equal to the Adjusted Treasury Rate, over (2) the principal amount of such Note on such redemption date.

“Adjusted Treasury Rate” means, with respect to any redemption date, (1) the average of the yields in each statistical release for the immediately preceding week designated “H.15” or any successor publication which is published by the Board of Governors of the Federal Reserve System and which establishes yields on actively traded United States Treasury securities adjusted to constant maturity under “U.S. government securities—Treasury constant maturities—nominal,” for the maturity corresponding to the Comparable Treasury Issue (if no maturity is within three months before or after the remaining term of the Notes to be redeemed,

31

yields for the two published maturities most closely corresponding to the Comparable Treasury Issue will be determined and the Adjusted Treasury Rate will be interpolated or extrapolated from such yields on a straight line basis, rounding to the nearest month) or (2) if such release (or any successor release) is not published during the week preceding the calculation date or does not contain such yields, the rate per year equal to the semi-annual equivalent yield-to-maturity of the Comparable Treasury Issue, calculated using a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such redemption date, in each case calculated on the third Business Day immediately preceding the date that the applicable redemption notice is first mailed or sent, in each case, plus 50 basis points.

“Comparable Treasury Issue” means the United States Treasury security selected by the Quotation Agent as having a maturity comparable to the remaining term of the Notes from the redemption date to November 15, 2025, that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of a maturity most nearly equal to November 15, 2025.

“Comparable Treasury Price” means, with respect to any redemption date, if clause (2) of the Adjusted Treasury Rate definition is applicable, the average of four, or such lesser number as is obtained by the Issuer, Reference Treasury Dealer Quotations for such redemption date.

“Quotation Agent” means the Reference Treasury Dealer selected by the Issuer.

“Reference Treasury Dealer” means either J.P. Morgan Securities, LLC and its successors and assigns or Merrill Lynch, Pierce, Fenner & Smith Incorporated and its successors and assigns.

“Reference Treasury Dealer Quotations” means with respect to each Reference Treasury Dealer and any redemption date, the average, as determined by the Issuer, of the bid and asked prices for the Comparable Treasury Issue, expressed in each case as a percentage of its principal amount, quoted in writing to the Issuer by such Reference Treasury Dealer at 5:00 p.m., New York City time, on the second Business Day immediately preceding the date that the applicable redemption notice is first mailed or sent.

“Remaining Scheduled Payments” means the remaining payments of principal of and interest on the Notes that would be due after the redemption date but for such redemption if the Notes matured on November 15, 2025. If the redemption date is not an interest payment date, the amount of the next succeeding scheduled interest payment on the Notes will be reduced by the amount of interest accrued thereon to the redemption date.

Selection and Notice of Redemption

If we are redeeming fewer than all the Notes at any time, the Trustee will select Notes on a pro rata basis, by lot or by such other method as the Trustee in its sole discretion shall deem to be fair and appropriate unless otherwise required by law or applicable stock exchange or depositary requirements, including the applicable procedures of DTC.

We will redeem Notes of $2,000 or less in whole and not in part. We will cause notices of redemption to be mailed by first-class mail (or delivered by electronic transmission in accordance with the applicable procedures of DTC) not less than 30 nor more than 60 days prior to the redemption date to each holder of Notes to be redeemed at its registered address with a copy to the Trustee.

If any Note is to be redeemed in part only, the notice of redemption that relates to that Note will state the portion of the principal amount thereof to be redeemed. Upon surrender of a Note that is redeemed or purchased in part, we will issue a new Note in a principal amount equal to the unredeemed portion of the original Note surrendered in the name of the holder thereof. Notes called for redemption become due on the date fixed for redemption. On and after the redemption date, interest ceases to accrue on Notes or portions of them called for redemption.

32

No Sinking Fund; Open Market Purchases

We are not required to make any sinking fund payments with respect to the Notes. However, under certain circumstances, we may be required to offer to purchase, Notes as described under the captions “—Change of Control Triggering Event.” We may at any time and from time to time purchase Notes in the open market, through privately negotiated transactions, exchange offers or otherwise.

Guarantees

As of the Issue Date, each Subsidiary of the Issuer that is a guarantor or obligor under the Credit Agreement will guarantee the Notes.

Each Guarantor will jointly and severally guarantee, on a senior unsecured basis, our obligations under the Notes. The obligations of each Guarantor under its Guarantee are designed to be limited as necessary to prevent such Guarantee from constituting a fraudulent conveyance under applicable law and, therefore, will be expressly limited to the maximum amount that such Guarantor could guarantee without such Guarantee constituting a fraudulent conveyance. This limitation, however, may not be effective to prevent such Guarantee from constituting a fraudulent conveyance. In addition, if a Guarantee were rendered voidable, it could be subordinated by a court to all other indebtedness (including guaranties and other contingent liabilities) of the applicable Guarantor, and, depending on the amount of such indebtedness, a Guarantor’s liability on its Guarantee could be reduced to zero. See “Risk Factors—Under certain circumstances a court could cancel the notes or the related guarantees under fraudulent conveyance laws. If that occurs, you may not receive any payments on the notes.”

Each Guarantor that makes a payment under its Guarantee will be entitled upon payment in full of all guaranteed obligations under the Indenture to a contribution from each other Guarantor in an amount equal to such other Guarantor’s pro rata portion of such payment based on the respective net assets of all the Guarantors at the time of such payment determined in accordance with GAAP.

The Guarantee of a Guarantor will be automatically released upon:

33

Ranking

The indebtedness evidenced by the Notes and the Guarantees will be senior unsecured obligations and will rank equally in right of payment with all other unsecured unsubordinated indebtedness of the Issuer or the applicable Guarantor, as the case may be, but will be effectively junior to all secured indebtedness, including the obligations of the Issuer and the Guarantors under the Credit Agreement and the 2023 Secured Notes, to the extent of the value of the assets securing such indebtedness.

As of September 29, 2017, on an as adjusted basis as described under “Capitalization”:

The Indenture contains no limitations on the amount of additional indebtedness that the Issuer and the Guarantors may incur and therefore the amount of such indebtedness could be substantial and, subject to the limitations set forth in the covenant described under “—Certain Covenants—Limitation on Liens,” such indebtedness may be secured indebtedness. The Indenture also does not limit the incurrence of unsecured indebtedness by our Subsidiaries that are Guarantors. The Indenture does limit the incurrence of unsecured indebtedness by our Subsidiaries that are not Guarantors as set forth in the covenant described under “—Certain Covenants—Limitation on Non-Guarantor Subsidiary Debt.” Moreover, the Indenture does not impose any limitation on the incurrence by us or such Subsidiaries of liabilities that are not considered indebtedness under the Indenture.

A substantial portion of our operations are conducted through our Subsidiaries. Most of our Subsidiaries are not guaranteeing the Notes, and, as described above under “—Guarantees,” Guarantees may be released under certain circumstances. In addition, our future Subsidiaries may not be required to guarantee the Notes. Claims of creditors of such non-Guarantor Subsidiaries, including trade creditors and creditors holding indebtedness or guarantees issued by such non-Guarantor Subsidiaries, and claims of preferred stockholders of such non-Guarantor Subsidiaries generally will have priority with respect to the assets and earnings of such non-Guarantor Subsidiaries over the claims of our creditors, including the holders. Accordingly, the Notes will be structurally subordinated to creditors (including trade creditors) and preferred stockholders, if any, of such non-Guarantor Subsidiaries.

As of September 29, 2017, the Issuer’s Subsidiaries that will not guarantee the Notes would have had approximately $3.4 billion of aggregate total liabilities (excluding intercompany transactions). In addition, for the twelve months ended September 29, 2017, these non-Guarantor Subsidiaries would have accounted for approximately 39% of our net sales and approximately 63% of our total operating income, and as of September 29, 2017, these non-Guarantor Subsidiaries would have accounted for approximately 83% of our total consolidated assets (excluding intercompany transactions).

Change of Control Triggering Event

Within 30 days following the occurrence of a Change of Control Triggering Event, unless we have exercised our option to redeem all the Notes as described under “—Optional Redemption,” each noteholder shall have the right to require that the Issuer make an offer to purchase such noteholder’s Notes at a purchase price in cash equal to 101% of the principal amount thereof on the date of purchase plus accrued and unpaid interest, if any, to but excluding the date of purchase.

34

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

Within 30 days following the occurrence of a Change of Control Triggering Event, unless we have exercised our option to redeem all the Notes as described under “—Optional Redemption,” we will mail (or deliver by electronic transmission in accordance with the applicable procedures of DTC) a notice to each noteholder with a copy to the Trustee (the “Change of Control Offer”) stating:

We will not be required to make a Change of Control Offer following a Change of Control Triggering Event if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in the Indenture applicable to a Change of Control Offer made by us and purchases all Notes validly tendered and not withdrawn under such Change of Control Offer or if the Issuer has exercised its option to redeem all the Notes pursuant to the provisions described under “—Optional Redemption.”

We will comply, to the extent applicable, with the requirements of Section 14(e) of the Exchange Act and any other securities laws or regulations in connection with the purchase of Notes as a result of a Change of Control Triggering Event. To the extent that the provisions of any securities laws or regulations conflict with the provisions of the covenant described hereunder, we will comply with the applicable securities laws and regulations and shall not be deemed to have breached our obligations under the covenant described hereunder by virtue of our compliance with such securities laws or regulations.

The Change of Control Triggering Event purchase feature of the Notes may in certain circumstances make more difficult or discourage a sale or takeover of the Issuer and, thus, the removal of incumbent management. We have no present intention to engage in a transaction involving a Change of Control, although it is possible that we could decide to do so in the future. Subject to the limitations discussed below, we could, in the future, enter into certain transactions, including acquisitions, refinancings or other recapitalizations, that would not constitute a Change of Control under the Indenture, but that could increase the amount of indebtedness outstanding at such time or otherwise affect our capital structure or credit ratings. Restrictions on our ability to incur additional secured indebtedness are contained in the covenant described under “—Certain Covenants—Limitation on Liens.” Such restrictions can only be waived with the consent of the holders of a majority in principal amount of the Notes then outstanding. Except for the limitations contained in such covenant, however, the Indenture will not contain any covenants or provisions that may afford holders of the Notes protection in the event of a highly leveraged transaction.

Holders may not be entitled to require us to purchase their Notes in certain circumstances involving a significant change in the composition of the Board of Directors, including in connection with a proxy contest.

The Credit Agreement provides that the occurrence of certain change of control events with respect to the Issuer would constitute a default thereunder. Future indebtedness that we may incur may contain prohibitions

35

on the occurrence of certain events that would constitute a Change of Control or require the purchase of such indebtedness upon a Change of Control. Moreover, the exercise by the holders of their right to require us to purchase the Notes could cause a default under such indebtedness, even if the Change of Control itself does not, due to the financial effect of such purchase on us. Finally, our ability to pay cash to the holders of Notes following the occurrence of a Change of Control may be limited by our then existing financial resources. There can be no assurance that sufficient funds will be available when necessary to make any required purchases. See “Risk Factors—We may not have the ability to raise the funds necessary to finance the change of control offer required by the indenture governing the notes.”

Notwithstanding anything to the contrary herein, a Change of Control Offer may be made in advance of a Change of Control Triggering Event, conditional upon such Change of Control Triggering Event, if a definitive agreement is in place for the Change of Control at the time of making of such Change of Control Offer. In such case, the notice shall state that, in the Issuer’s (or such third party offeror’s) discretion, the Change of Control purchase date may be delayed until such time as the Change of Control Triggering Event shall have occurred, or such repurchase may not occur and such notice may be rescinded in the event that the Change of Control Triggering Event shall not have occurred by the Change of Control purchase date, or by the Change of Control purchase date as so delayed.

The phrase “all or substantially all,” as used with respect to the assets of the Issuer in the definition of “Change of Control,” is subject to interpretation under applicable state law, and its applicability in a given instance would depend upon the facts and circumstances. As a result, there may be a degree of uncertainty in ascertaining whether a sale or transfer of “all or substantially all” the assets of the Issuer has occurred in a particular instance, in which case a holder’s ability to obtain the benefit of these provisions could be unclear.

The provisions under the Indenture relative to our obligation to make an offer to purchase the Notes as a result of a Change of Control Triggering Event may be waived or modified with the written consent of the holders of a majority in principal amount of the Notes.

For purposes of this discussion of a repurchase of the Notes following a Change of Control Triggering Event:

A “Change of Control” means the occurrence of any of the following:

Notwithstanding the foregoing:

36

Certain Covenants

Consolidation, Merger, Sale or Conveyance

The Indenture will provide that:

(a)        the Issuer may not (i) consolidate with or merge into any other entity or (ii) convey, transfer or lease all or substantially all of the properties and assets of the Issuer and its subsidiaries taken as a whole, unless:

In case of any such consolidation, merger, conveyance or transfer (but not lease), the successor entity will succeed to and be substituted for the Issuer as obligor on the Notes, with the same effect as if it had been named in the Indenture as the Issuer.

37

Notwithstanding clauses (a) and (b) above, (x) clauses (a)(2)-(3) and (b)(2)-(3) of this “—Consolidation, Merger, Sale or Conveyance” covenant will not apply to a merger, transfer or conveyance or other disposition of assets between or among the Issuer and the Guarantors and (y) this “—Consolidation, Merger, Sale or Conveyance” covenant will not apply to any Subsidiary consolidating with, merging into or transferring all or part of its properties and assets to the Issuer and/or one or more Guarantors.

In addition, notwithstanding the foregoing, any Guarantor may (x) merge with an Affiliate of the Issuer solely for the purpose of reincorporating the Guarantor in the United States, any state thereof, the District of Columbia or any territory thereof or (y) convert into a corporation, partnership, limited partnership, limited liability company or trust organized or existing under the laws of the jurisdiction of organization of such Guarantor.

Limitation on Liens

The Issuer will not, and will not permit any of its Subsidiaries to, create, incur, issue, assume or guarantee any Debt secured by a Lien upon (a) any Property of the Issuer or such Subsidiary, or (b) any shares of Capital Stock or other securities issued by any Subsidiary of the Issuer and owned by the Issuer or any Subsidiary of the Issuer, whether owned on the Issue Date or thereafter acquired, without effectively providing concurrently that the Notes then outstanding under the Indenture are secured equally and ratably with or, at the option of the Issuer, prior to such Debt so long as such Debt shall be so secured.

The foregoing restriction shall not apply to, and there shall be excluded from Debt (or any guarantee thereof) in any computation under such restriction, Debt (or any guarantee thereof) secured by:

Notwithstanding the restrictions described above, the Issuer and any Subsidiaries of the Issuer may create, incur, issue, assume or guarantee Debt secured by Liens without equally and ratably securing the Notes then outstanding if, at the time of such creation, incurrence, issuance, assumption or guarantee, after giving effect thereto and to the retirement of any Debt which is concurrently being retired, the aggregate amount of all such Debt secured by Liens which would otherwise be subject to such restrictions (excluding, for the purposes of determining such amount, any Debt (or any guarantee thereof) secured by Liens permitted as described in clauses (1)-(11) of the immediately preceding paragraph) plus the aggregate amount of Non-Guarantor Subsidiary Debt outstanding at such time (excluding, for the purposes of determining such amount, any Non-Guarantor Subsidiary Debt (or any guarantee thereof) permitted as described in clauses (1)-(6) of the second paragraph under “— Limitation on Non-Guarantor Subsidiary Debt” plus all Attributable Debt of the Issuer and the Subsidiaries of the Issuer in respect of Sale/ Leaseback Transactions with respect to Properties (with the exception of such transactions that are permitted under, in each case without duplication, clauses (1)-(4) of the first sentence of the first paragraph under “—Limitation on Sale/Leaseback Transactions” below) would not exceed the greater of (x) $1,500 million and (y) the amount that would cause the Consolidated Priority Debt Ratio to exceed 2.50 to 1.00. The Issuer or any of its Subsidiaries also may, without equally and ratably securing the Notes, extend, renew, substitute, replace, refinance or refund any Debt secured by Liens permitted pursuant to the preceding sentence; provided that any Debt incurred to so extend, renew, substitute, replace, refinance or refund shall be incurred within 270 days of the maturity, retirement or other repayment or prepayment (including any such repayment pursuant to amortization obligations) of the Debt secured by Liens being extended, renewed, substituted, replaced, refinanced or refunded and the outstanding amount of Debt incurred to so extend, renew, substitute, replace, refinance or refund shall not exceed the outstanding amount of the Debt secured by Liens being extended, renewed, substituted, replaced, refinanced or refunded plus any premiums or fees (including tender premiums) or other reasonable amounts payable, plus the amount of fees, expenses and other costs incurred, in connection with any such extension, renewal, substitution, replacement, refinancing or refunding.

For purposes of the foregoing covenant, in the event that any Lien meets the criteria of more than one of the types of Liens described above, the Issuer, in its sole discretion, will classify, and may reclassify, such Liens and only be required to include the amount and type of such Liens in one of the numbered paragraphs above or the immediately preceding paragraph, and Liens may be divided and classified and reclassified into more than one of the types of Liens described above. In addition, for purposes of calculating compliance with the foregoing covenant, in no event will the amount of any Debt or Liens securing any Debt be required to be included more than once despite the fact more than one Person is or becomes liable with respect to such Debt and despite the fact such Debt is secured by the assets of more than one Person (for example, and for avoidance of doubt, in the case where there are Liens on assets of one or more of the Issuer and its Restricted Subsidiaries securing any Debt, the amount of such Debt secured shall only be included once for purposes of such calculations).

For the avoidance of doubt, the loans and commitments outstanding under the Credit Agreement and the principal amount of 2023 Secured Notes outstanding on the Issue Date shall be secured pursuant to clause (9) above and may not be reclassified.

Limitation on Non-Guarantor Subsidiary Debt

The Issuer will not permit any of its Subsidiaries that is not a Guarantor (each such Subsidiary, a “Non-Guarantor Subsidiary”) to create, assume, incur, guarantee or otherwise become liable for any Debt (any

40

such Debt or guarantee, “Non-Guarantor Subsidiary Debt”), without causing such Non-Guarantor Subsidiary (other than any Excluded Subsidiary) to guarantee the payment of the principal of, premium, if any, and interest on the Notes on an unsecured unsubordinated basis until such time as such Debt or guarantee, as the case may be, is no longer outstanding or in effect.

The foregoing restriction shall not apply to, and there shall be excluded from Non-Guarantor Subsidiary Debt in any computation under such restriction, Non-Guarantor Subsidiary Debt constituting:

(1)        Non-Guarantor Subsidiary Debt of a Person existing at the time such Person is merged into or consolidated with or otherwise acquired by the Issuer or any Subsidiary of the Issuer or otherwise becomes a Subsidiary of the Issuer (or arising thereafter pursuant to contractual commitments entered into prior to such Person becoming a Subsidiary) or at the time of a sale, lease or other disposition of the properties and assets of such Person (or a division thereof) as an entirety or substantially as an entirety to a Subsidiary of the Issuer (or arising thereafter pursuant to contractual commitments entered into prior to such Person becoming a Subsidiary) and is assumed by such Subsidiary, other than any increase in the amount of such Non-Guarantor Subsidiary Debt (including any increase in the amount of such Non-Guarantor Subsidiary Debt arising pursuant to contractual commitments entered into prior to such acquisition) incurred in contemplation thereof; provided that any such Non-Guarantor Subsidiary Debt is not guaranteed by any other Subsidiary of the Issuer (other than any Guarantee existing at the time of such merger, consolidation or sale, lease or other disposition of properties and assets and that was not issued in contemplation thereof);

(2)        Non-Guarantor Subsidiary Debt owed to the Issuer or any Subsidiary or under guarantees of any such Non-Guarantor Subsidiary Debt;

(3)        Non-Guarantor Subsidiary Debt with respect to a Permitted Receivables Financing;

(4)        Non-Guarantor Subsidiary Debt permitted to be secured by Liens permitted by clauses (5) and (11) of the second paragraph under the heading “—Limitation on Liens” (whether or not such Non-Guarantor Subsidiary Debt is in fact secured by such Liens) and any Guarantees thereof;

(5)        (x) Non-Guarantor Subsidiary Debt in an aggregate amount not to exceed $1,500 million and (y) any extension, renewal, replacement or refunding of any Guarantor Subsidiary Debt (or any guarantee thereof) referred to in the foregoing clause (x); provided that any such Non-Guarantor Subsidiary Debt incurred to so extend, renew, substitute, replace, refinance or refund shall be incurred within 270 days of the maturity, retirement or other repayment or prepayment (including any such repayment pursuant to amortization obligations with respect to such Non-Guarantor Subsidiary Debt) of the Non-Guarantor Subsidiary Debt referred to in the foregoing clause (x) and the outstanding amount of the Non-Guarantor Subsidiary Debt incurred to so extend, renew, substitute, replace, refinance or refund shall not exceed the outstanding amount of Non-Guarantor Subsidiary Debt being extended, renewed, substituted, replaced, refinanced or refunded plus any premiums or fees (including tender premiums) or other reasonable amounts payable, plus the amount of fees, expenses and other costs incurred, in connection with any such extension, renewal, substitution, replacement, refinancing or refunding; or

(6)        Non-Guarantor Subsidiary Debt outstanding on the Issue Date and any extension, renewal, substitution, replacement, refinancing or refunding of any Non-Guarantor Subsidiary Debt existing on the Issue Date or referred to in clauses (1), (2), (3) or (4); provided that any Non-Guarantor Subsidiary Debt incurred to so extend, renew, substitute, replace, refinance or refund shall be incurred within 270 days of the maturity, retirement or other repayment or prepayment (including any such repayment pursuant to amortization obligations with respect to such Non-Guarantor Subsidiary Debt) of the Non-Guarantor Subsidiary Debt referred to in this clause or clauses (1), (2), (3) or (4) above and the outstanding amount of the Non-Guarantor Subsidiary Debt incurred to so extend, renew, substitute, replace, refinance or refund shall not exceed the outstanding amount of Non-Guarantor Subsidiary Debt being extended, renewed, substituted, replaced, refinanced or refunded plus any

41

premiums or fees (including tender premiums) or other reasonable amounts payable, plus the amount of fees, expenses and other costs incurred, in connection with any such extension, renewal, substitution, replacement, refinancing or refunding.

Notwithstanding the restrictions described above, any Non-Guarantor Subsidiary of the Issuer may create, assume, incur, guarantee or otherwise become liable for Non-Guarantor Subsidiary Debt that would otherwise be subject to the restrictions set forth in the first paragraph of this covenant, without guaranteeing the notes, if after giving effect thereto, the aggregate amount of Non-Guarantor Subsidiary Debt outstanding at such time (excluding, for purposes of determining such amount, any Non-Guarantor Subsidiary Debt (or any guarantee thereof) permitted as described in clauses (1)-(6) of the preceding paragraph) plus the aggregate principal amount of Debt secured by Liens on Properties then outstanding (excluding, for purposes of determining such amount, any such Debt secured by Liens described in clauses (1)-(11) of the second paragraph under the heading “—Limitation on Liens”) that are not equally and ratably secured with the outstanding Notes (or secured on a basis junior to the outstanding Notes) plus all Attributable Debt of the Issuer and the Subsidiaries of the Issuer in respect of Sale/ Leaseback Transactions with respect to Properties (with the exception of such transactions that are permitted under clauses (1)-(4) of the first sentence of the first paragraph under “—Limitation on Sale/Leaseback Transactions” below), in each case without duplication, would not exceed the greater of (x) $1,500 million and (y) the amount that would cause the Consolidated Priority Debt Ratio to exceed 2.50 to 1.00. Any Domestic Subsidiary also may, without guaranteeing the payment of the principal of, premium, if any, and interest on the Notes, extend, renew, substitute, replace, refinance or refund any Non-Guarantor Subsidiary Debt permitted pursuant to the preceding sentence; provided that any Non-Guarantor Subsidiary Debt incurred to so extend, renew, substitute, replace, refinance or refund shall be incurred within 270 days of the maturity, retirement or other repayment or prepayment (including any such repayment pursuant to amortization obligations with respect to such Non-Guarantor Subsidiary Debt) of the Non-Guarantor Subsidiary Debt being extended, renewed, substituted, replaced, refinanced or refunded and the outstanding amount of the Non-Guarantor Subsidiary Debt incurred to so extend, renew, substitute, replace, refinance or refund shall not exceed the outstanding amount of Non-Guarantor Subsidiary Debt being extended, renewed, substituted, replaced, refinanced or refunded plus any premiums or fees (including tender premiums) or other reasonable amounts payable, plus the amount of fees, expenses and other costs incurred, in connection with any such extension, renewal, substitution, replacement, refinancing or refunding.

For purposes of the foregoing covenant, in the event that any Non-Guarantor Subsidiary Debt meets the criteria of more than one of the types of Non-Guarantor Subsidiary Debt described above, the Issuer, in its sole discretion, will classify, and may reclassify, such Non-Guarantor Subsidiary Debt and only be required to include the amount and type of such Non-Guarantor Subsidiary Debt in one of the numbered paragraphs above or the immediately preceding paragraph, and Non-Guarantor Subsidiary Debt may be divided and classified and reclassified into more than one of the types of Non-Guarantor Subsidiary Debt described above. In addition, for purposes of calculating compliance with the foregoing covenant, in no event will the amount of any Non-Guarantor Subsidiary Debt be required to be included more than once despite the fact more than one Person is or becomes liable with respect to any related Debt (for example, and for avoidance of doubt, in the case where more than one Domestic Subsidiary incurs Non-Guarantor Subsidiary Debt or otherwise becomes liable for such Non-Guarantor Subsidiary Debt, the amount of such Non-Guarantor Subsidiary Debt shall only be included once for purposes of such calculations).

In addition, the restrictions described above shall not restrict any guarantees by the Issuer or its Subsidiaries of operating leases of joint ventures.

Limitation on Sale/Leaseback Transactions

The Issuer will not, and will not permit any Subsidiary of the Issuer to, enter into any Sale/ Leaseback Transaction with respect to any Property unless:

42

(b) the aggregate amount of Non-Guarantor Subsidiary Debt outstanding at such time (excluding, for the purposes of determining such amount, any Non-Guarantor Subsidiary Debt (or any guarantee thereof) permitted as described in clauses (1)-(6) of the second paragraph under “— Limitation on Non-Guarantor Subsidiary Debt”), plus

(c) the aggregate principal amount of Debt secured by Liens on Properties then outstanding (excluding, for the purposes of determining such amount, any such Debt secured by Liens described in clauses (1)-(11) of the second paragraph under the heading “—Limitation on Liens”) that are not equally and ratably secured with the outstanding Notes (or secured on a basis junior to the outstanding Notes), in each case without duplication, would not exceed the greater of (x) $1,500 million and (y) the amount that would cause the Consolidated Priority Debt Ratio to exceed 2.50 to 1.00.

SEC Reports

As long as the Notes are outstanding, the Issuer shall file with the Trustee, within 15 days after the Issuer has filed the same with the SEC, copies of the annual reports and of the information, documents and reports (or copies of such portions of any of the foregoing as the SEC may prescribe) that the Issuer may be required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act (other than confidential filings, documents subject to confidential treatment and correspondence with the SEC); provided that the electronic filing of the foregoing reports by the Issuer on the SEC’s EDGAR system (or any successor system) shall be deemed to satisfy the Issuer’s delivery obligations to the Trustee, it being understood that the Trustee shall not be responsible for determining whether such filings have been made. The Issuer shall also comply with the other provisions of TIA § 314(a), to the extent applicable.

Delivery of any reports, information and documents to the Trustee will be for informational purposes only and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Issuer’s compliance with any of its covenants hereunder (as to which the Trustee will be entitled to rely exclusively on Officer’s Certificates).

43

Defaults

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

However, a default under clauses (4), (5) and (8) will not constitute an Event of Default until the Trustee or the holders of 30% in principal amount of the outstanding Notes notify the Issuer (with a copy to the Trustee if given by the holders) of the default and the Issuer does not cure such default within the time specified after receipt of such notice. Any default for the failure to deliver any report within the time periods prescribed in the covenant described under “—Certain Covenants—SEC Reports” or to deliver any notice or certificate pursuant to any other provision of the Indenture shall be deemed to be cured upon the subsequent delivery of any such report, notice or certificate, even though such delivery is not within the prescribed period specified.

If an Event of Default occurs and is continuing, the Trustee or the holders of at least 30% in principal amount of the outstanding Notes may declare the principal of and accrued but unpaid interest, if any, and premium, if any, on all the Notes to be due and payable. Upon such declaration, such principal, interest and premium, if any, shall be due and payable immediately. If an Event of Default relating to certain events of bankruptcy, insolvency or reorganization of the Issuer occurs and is continuing, the principal of and interest (and premium, if any) on all the Notes will ipso facto become and be immediately due and payable without any declaration or other act on the part of the Trustee or any holders of the Notes. Under certain circumstances, the holders of a majority in principal amount of the outstanding Notes may rescind any such acceleration with respect to the Notes and its consequences.

In case an Event of Default occurs and is continuing, the Trustee will be under no obligation to exercise any of the rights or powers under the Indenture at the request or direction of any of the holders of the Notes

44

unless such holders have offered to the Trustee indemnity or security satisfactory to the Trustee against any loss, liability or expense and then only to the extent required by the terms of the Indenture. Except to enforce the right to receive payment of principal, premium (if any) or interest when due, no holder of a Note may pursue any remedy with respect to the Indenture or the Notes unless:

Subject to certain restrictions, the holders of a majority in principal amount of the outstanding Notes are given the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or of exercising any trust or power conferred on the Trustee. The Trustee, however, may refuse to follow any direction that conflicts with law or the Indenture or that the Trustee determines is unduly prejudicial to the rights of any other holder of a Note (it being understood that the Trustee does not have an affirmative duty to ascertain whether or not any such directions are unduly prejudicial to such holders) or that would involve the Trustee in personal liability.

If a Default occurs, is continuing and is actually known to the Trustee, the Trustee must mail (or deliver by electronic transmission in accordance with the applicable procedures of DTC) to each holder of the Notes notice of the Default within 90 days after being notified by the Issuer. Except in the case of a Default in the payment of principal of, interest or premium on any Note, the Trustee may withhold notice if it determines that withholding notice is not opposed to the interest of the holders of the Notes. In addition, we are required to deliver to the Trustee, within 120 days after the end of each fiscal year, a certificate indicating whether the signers thereof know of any Default that occurred during the previous year. We are required to deliver to the Trustee, within 30 days after the Issuer obtains knowledge of the occurrence thereof, written notice of any event which would constitute certain Defaults, their status and what action we are taking or propose to take in respect thereof.

Amendments and Waivers

Subject to certain exceptions, the Indenture may be amended with the consent of the holders of a majority in principal amount of the Notes then outstanding affected by such amendment (including consents obtained in connection with a tender offer or exchange for the Notes) and any past default or compliance with any provisions may also be waived with the consent of the holders of a majority in principal amount of the Notes then outstanding. However, without the consent of each holder of an outstanding Note affected thereby, an amendment or waiver may not, among other things:

45

Notwithstanding the preceding, without the consent of any holder of the Notes, the Issuer, the Guarantors and Trustee may amend or supplement the Indenture:

The consent of the holders of the Notes is not necessary under the Indenture to approve the particular form of any proposed amendment. It is sufficient if such consent approves the substance of the proposed amendment.

Transfer

The Notes will be issued in registered form and will be transferable only upon the surrender of the Notes being transferred for registration of transfer. We may require payment of a sum sufficient to cover any tax, assessment or other governmental charge payable in connection with certain transfers and exchanges.

46

Defeasance

The Issuer may, at its option and at any time, elect to have all of its obligations and the obligations of the Guarantors with respect to the Notes discharged with respect to the Indenture and the outstanding Notes and the Guarantees thereof issued under the Indenture (“legal defeasance”) except for:

If the Issuer exercises the legal defeasance option, the Guarantees in effect at such time will be automatically released.

The Issuer at any time may be released from its obligations described under “—Change of Control Triggering Event” and under the covenants described under “—Certain Covenants” (other than “—Consolidation, Merger, Sale or Conveyance”) (“covenant defeasance”).

If the Issuer exercises the covenant defeasance option, the Guarantees in effect at such time will be automatically released.

The Issuer may exercise its legal defeasance option notwithstanding its prior exercise of its covenant defeasance option. If the Issuer exercises its legal defeasance option, payment of the Notes may not be accelerated because of an Event of Default. If the Issuer exercises its covenant defeasance option, an Event of Default specified in clause (3), clause (4), clause (5), clause (7) (other than with respect to the Issuer), clause (8) or clause (9) under “—Defaults” above, in each case, shall not constitute an Event of Default.

In order to exercise either legal defeasance or covenant defeasance under the Indenture:

47

Satisfaction and Discharge

The Indenture will be discharged, and will cease to be of further effect as to all Notes, when either:

(b) no Default or Event of Default has occurred and is continuing on the date of such deposit or will occur as a result of such deposit (other than a Default or an Event of Default resulting from the borrowing of funds to be applied to make such deposit and any similar and simultaneous deposit relating to other indebtedness and, in each case, the granting of Liens in connection therewith);

(c) the Issuer or any Guarantor has paid or caused to be paid all sums payable by the Issuer under the Indenture; and

(d) the Issuer has delivered irrevocable instructions to the Trustee to apply the deposited money toward the payment of the Notes at maturity or the redemption date, as the case may be.

In addition, the Issuer shall deliver to the Trustee an Officer’s Certificate and an Opinion of Counsel (which Opinion of Counsel may be subject to customary assumptions and exclusions) each stating that all conditions precedent to satisfaction and discharge have been satisfied.

Concerning the Trustee

U.S. Bank National Association is the Trustee under the Indenture and has been appointed by the Issuer as registrar and paying agent and DTC custodian with regard to the Notes. The Issuer may from time to time

48

conduct other banking transactions, including lending transactions, or maintaining deposit accounts with U.S. Bank National Association in the ordinary course of business.

If the Trustee becomes a creditor of the Issuer or any Guarantor, the Indenture limits the right of the Trustee to obtain payment of claims in certain cases, or to realize on certain property received in respect of any such 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 Indenture has been qualified under the Trust Indenture Act) or resign.

No Personal Liability of Directors, Officers, Employees and Stockholders

No past, present or future director, officer, employee, incorporator, member, partner or stockholder of the Issuer or any Guarantor, as such, shall have any liability for any obligations of the Issuer or any Guarantor (other than the Issuer in respect of the Notes and each Guarantor in respect of its Guarantee) under the Notes, the Guarantees or the Indenture 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 waiver may not be effective to waive liabilities under the federal securities laws.

Governing Law; Jury Trial Waiver

The Indenture, the Notes and the Guarantees will be governed by, and construed in accordance with, the laws of the State of New York. The Indenture will provide that any legal suit, action or proceeding arising out of or based upon the Indenture or the transactions contemplated thereby may be instituted in the federal courts of the United States of America located in the City of New York or the courts of the State of New York in each case located in the City of New York, and each party to the Indenture will submit to the non-exclusive jurisdiction of such courts in any such suit, action or proceeding. The Indenture will provide that the Issuer, the Guarantors and the Trustee, and each holder of a Note by its acceptance thereof, irrevocably waives, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to the Indenture, the Notes, the Guarantees, or any transaction contemplated thereby.

U.S. FEDERAL INCOME TAX CONSIDERATIONS

The following is a summary of material U.S. federal income tax considerations of the purchase, ownership and disposition of the notes. The summary is based on laws, regulations, rulings and decisions now in effect, all of which are subject to change (possibly with retroactive effect). The discussion does not deal with special classes of investors, such as dealers in securities or currencies, traders in securities electing to mark to market, banks, financial institutions, insurance companies, tax-exempt entities, entities classified as partnerships and the partners therein, persons holding notes as a position in a “straddle” or conversion transaction, or as part of a “synthetic security” or other integrated financial transaction, U.S. Holders (as defined herein) who hold the notes through non-U.S. brokers or other non-U.S. intermediaries, persons subject to the alternative minimum tax, U.S. expatriates, nonresident alien individuals present in the United States for more than 182 days in a taxable year, or U.S. Holders that have a functional currency other than the U.S. dollar. This summary addresses only holders that purchase the notes upon their original issue from the initial purchaser at the issue price (the first price at which a substantial amount of the notes is sold for money to the public, not including bond houses, brokers or similar persons or organizations acting in the capacity of underwriters, placement agents or wholesalers) and that hold the notes as “capital assets” within the meaning of Section 1221 of the Internal Revenue Code of 1986, as amended (the “Code”). This summary does not address any U.S. taxes other than U.S. federal income taxes (such as estate or gift taxes), the tax on net investment income, or any state, local or foreign tax laws. Prospective investors should consult their tax advisors as to the particular tax consequences to them of purchasing, holding and disposing of the notes. As used in this offering memorandum, the term U.S. Holder means a beneficial owner of notes (a “Holder”) that is, for U.S. federal income tax purposes, an individual who is a citizen or resident of the United States, a corporation created or organized under the laws of the United States, any state thereof or the District of Columbia, or any other person that is subject to U.S. federal income tax on a net income basis in respect of the notes. A non-U.S. person whose income in respect of the Notes is effectively connected with its conduct of a trade or business in the United States is a U.S. Holder. Such persons should consult their own tax advisors regarding the U.S. federal income tax consequences (including the potential application of the branch profits tax) of the purchase, ownership and disposition of the notes. A “Non-U.S. Holder” is a beneficial owner of a note that is, for U.S. federal income tax purposes, an individual, corporation, estate, or trust that is not a U.S. Holder.

Under recently enacted legislation, U.S. Holders that use an accrual method of accounting for tax purposes generally will be required to include certain amounts in income no later than the time such amounts are reflected on certain financial statements. The application of this rule thus may require the accrual of income earlier than would be the case under the general tax rules described below, although the precise application of this rule is unclear at this time. This rule is effective for tax years beginning after December 31, 2017 or, for debt instruments issued with original issue discount, for tax years beginning after December 31, 2018. U.S. Holders that use an accrual method of accounting should consult with their tax advisors regarding the potential applicability of this legislation to their particular situation.

U.S. Holders

Payments of Stated Interest

Stated interest on a note will generally be taxable to a U.S. Holder as ordinary income at the time it is paid or accrued in accordance with the U.S. Holder’s regular method of accounting for U.S. federal income tax purposes. It is expected that the notes will not be issued with more than a de minimis amount of original issue discount (“OID”). If, contrary to expectations, the stated principal amount of the notes exceeds their issue price by more than a statutorily defined de minimis amount, the notes will be treated as issued with OID in an amount equal to such excess, and a U.S. Holder generally will be required to include OID in gross income, as ordinary income, as it accrues under a “constant-yield method” before the receipt of cash attributable to such OID, regardless of the U.S. Holder’s regular method of accounting for U.S. federal income tax purposes. The remainder of this discussion assumes that the notes will not be treated as issued with more than a de minimis amount of OID.

Sale, Exchange, Redemption, Retirement or Other Taxable Disposition

Upon the sale, exchange, redemption or retirement of a note, a U.S. Holder generally will recognize gain or loss equal to the difference between the amount received for the note (less any accrued interest, which will be

64

taxable as such) and the U.S. Holders’ adjusted tax basis in the note. A U.S. Holder’s adjusted basis in a note generally will be the U.S. Holder’s cost therefor. Any such gain or loss will generally constitute capital gain or loss and will be long-term capital gain or loss if such note was held for more than one year. Long-term capital gains of non-corporate holders are generally eligible for reduced rates of taxation, and the deductibility of capital losses is subject to certain limitations.

Non-U.S. Holders

If you are a Non-U.S. Holder, except as otherwise indicated below under “FATCA” or “Information Reporting and Backup Withholding,” under the portfolio interest exemption you will not be subject to U.S. federal withholding tax on payments of interest on the notes, provided that you (a) do not actually or constructively own 10% or more of the combined voting power of all classes of our stock that are entitled to vote, (b) are not a controlled foreign corporation related to us through actual or constructive equity ownership, and (c) have provided an applicable IRS Form W-8 to the applicable withholding agent, properly completed and signed under penalties of perjury, establishing your status as a Non-U.S. Holder. If any of the foregoing requirements is not met, payments of interest on a note generally will be subject to U.S. federal withholding tax at a 30% rate (or lower applicable treaty rate). Furthermore, except as otherwise indicated below under “FATCA” or “Information Reporting and Backup Withholding,” you generally will not be subject to U.S. federal income tax or withholding tax on gain realized on the sale, redemption, retirement or other taxable disposition of the notes.

FATCA

Under the U.S. tax rules known as the Foreign Account Tax Compliance Act (“FATCA”), a holder of notes will generally be subject to 30% U.S. withholding tax on interest payments on the notes (and, starting on January 1, 2019, principal payments on the notes and gross proceeds from the sale or other taxable disposition of the notes) if the holder is not FATCA compliant, or holds its notes through a foreign financial institution that is not FATCA compliant. In order to be treated as FATCA compliant, a holder must provide to the applicable withholding agent certain documentation (usually an IRS Form W-8BEN or W-8BEN-E) containing information about its identity, its FATCA status, and if required, its direct and indirect U.S. owners. For a foreign financial institution to be FATCA compliant, it generally must enter into an agreement with the U.S. government to report, on an annual basis, certain information regarding accounts with or interests in the institution held by certain United States persons and by certain non-U.S. entities that are wholly or partially owned by United States persons, or must satisfy similar requirements under an intergovernmental agreement between the United States and another country (an “IGA”). These requirements may be modified by the adoption or implementation of a particular IGA or by future U.S. Treasury Regulations. If any taxes are required to be deducted or withheld from any payments in respect of the notes as a result of a beneficial owner or intermediary’s failure to comply with the foregoing rules, no additional amounts will be paid on the notes as a result of the deduction or withholding of such tax.

Documentation that holders provide in order to be treated as FATCA compliant may be reported to the IRS and other tax authorities, including information about a holder’s identity, its FATCA status, and if applicable, its direct and indirect U.S. owners. You should consult your own tax advisers about how information reporting and the possible imposition of withholding tax under FATCA may apply to your investment in the notes.

Information Reporting and Backup Withholding

Information returns will be filed with the IRS in connection with payments on the notes made to, and the proceeds of dispositions of notes effected by, certain U.S. Holders. In addition, certain U.S. Holders may be subject to backup withholding in respect of such amounts if they do not provide their taxpayer identification numbers to the person from whom they receive payments. Non-U.S. Holders may be required to comply with applicable certification procedures to establish that they are not U.S. Holders in order to avoid the application of such information reporting requirements and backup withholding. The amount of any backup withholding from a payment to a U.S. Holder or a Non-U.S. Holder will be allowed as a credit against the holder’s U.S. federal income tax liability and may entitle the holder to a refund, provided that the required information is timely furnished to the IRS.

UNDERWRITING

Merrill Lynch, Pierce, Fenner & Smith Incorporated and J.P. Morgan Securities LLC are acting as representatives (together, the “Representatives”) of each of the underwriters named below. Subject to the terms and conditions set forth in an underwriting agreement among us and the underwriters, we have agreed to sell to the underwriters, and each of the underwriters has agreed, severally and not jointly, to purchase from us, the principal amount of notes set forth opposite its name below.

Subject to the terms and conditions set forth in the underwriting agreement, the underwriters have agreed, severally and not jointly, to purchase all of the notes sold under the underwriting agreement, if any of these notes are purchased. If an underwriter defaults, the underwriting agreement provides that the purchase commitments of the nondefaulting underwriters may be increased or the underwriting agreement may be terminated. The underwriters may offer and sell notes through certain of their affiliates.

We have agreed to indemnify the underwriters against certain liabilities, including liabilities under the Securities Act of 1933, as amended (“Securities Act”), or to contribute to payments the underwriters may be required to make in respect of those liabilities.

The underwriters are offering the notes, subject to prior sale, when, as and if issued to and accepted by them, subject to approval of legal matters by their counsel, including the validity of the notes, and other conditions contained in the underwriting agreement, such as the receipt by the underwriters of officer’s certificates and legal opinions. The underwriters reserve the right to withdraw, cancel or modify offers to the public and to reject orders in whole or in part.

We expect that the delivery of the notes will be made against payment therefor on or about February 13, 2018, which will be the tenth business day following the date of pricing of the notes (such settlement cycle being herein referred to as “T+10”). Under Rule 15c6-1 of the Securities Exchange Act of 1934, as amended, trades in the secondary market are required to settle in two business days, unless the parties to any such trade expressly agree otherwise. Accordingly, underwriters who wish to trade notes more than two business days prior to February 13, 2018 will be required, by virtue of the fact that the notes initially settle in T+10, to specify an alternate settlement arrangement at the time of any such trade to prevent a failed settlement. Underwriters of the notes who wish to trade the notes during such period should consult their advisors.

66

Commissions and Discounts

The Representatives have advised us that the underwriters propose initially to offer the notes to the public at the public offering price set forth on the cover page of this prospectus. After the initial offering, the public offering price or any other term of the offering may be changed. The underwriters may offer and sell notes through certain of their respective affiliates.

The following table shows the underwriting discounts and commissions to be paid by us to the underwriters in connection with this offering (expressed as a percentage of the principal amount of the notes).

The expenses of the offering, not including the underwriting discount, are estimated at $5,500,000 and are payable by us.

New Issues of Notes

The notes are new issues of securities with no established trading markets. We do not intend to apply for listing of the notes on any national securities exchange or for inclusion of the notes on any automated dealer quotation system. We have been advised by the underwriters that they presently intend to make a market in the notes after completion of the offering. However, they are under no obligation to do so and may discontinue any market-making activities at any time without any notice. We cannot assure the liquidity of the trading markets for the notes or that active public markets for the notes will develop. If active public trading markets for the notes do not develop, the market prices and liquidity of the notes may be adversely affected. If the notes are traded, they may trade at a discount from their initial offering price, depending on prevailing interest rates, the market for similar securities, our operating performance and financial condition, general economic conditions and other factors.

No Sales of Similar Securities

In the underwriting agreement, we have agreed that we will not offer or sell any of our debt securities (other than the notes offered pursuant to this prospectus) for a period of 60 days after the date of this prospectus without the prior consent of Merrill Lynch, Pierce, Fenner & Smith Incorporated and J.P. Morgan Securities LLC.

Short Positions

In connection with the offering of the notes, the underwriters may engage in overallotment, stabilizing transactions and syndicate covering transactions. Overallotment involves sales in excess of the offering size, which creates a short position for the underwriters. Stabilizing transactions involve bids to purchase the notes in the open market for the purpose of pegging, fixing or maintaining the price of the notes. Syndicate covering transactions involve purchases of the notes in the open market after the distribution has been completed in order to cover short positions. Stabilizing transactions and syndicate covering transactions may cause the price of the notes to be higher than it would otherwise be in the absence of those transactions. If the underwriters engage in stabilizing or syndicate covering transactions, they may discontinue them at any time.

Other Relationships

The underwriters and their respective affiliates are full service financial institutions engaged in various activities, which may include securities trading, commercial and investment banking, financial advisory,

67

investment management, investment research, principal investment, hedging, financing and brokerage activities. Some of the underwriters and their affiliates have engaged in, and may in the future engage in, investment banking and other commercial dealings in the ordinary course of business with us or our affiliates. They have received, or may in the future receive, customary fees and commissions for these transactions. JPMorgan Chase Bank, N.A., an affiliate of J.P. Morgan Securities LLC, one of the Representatives of this offering, serves as the administrative agent and collateral agent, and certain of the underwriters and/or their respective affiliates serve as a lead arrangers, joint bookrunners, co-syndication agents and/or lenders, in each case, under our senior credit facilities and have received, and may in the future receive, customary fees for such roles. In addition, the net proceeds of this offering are being used to redeem a portion of our 2024 Unsecured Notes. Certain of the underwriters and/or their respective affiliates are holders of the 2024 Unsecured Notes and, as a result, will receive a pro rata portion of such net proceeds from this offering used in connection with such redemption of the 2024 Unsecured Notes. On November 29, 2017, we increased the size of the Revolving Credit Facility, for which certain of the underwriters and/or certain of their respective affiliates provided a portion of the commitment for such increase. In addition, certain of the underwriters are also serving as initial purchasers under the concurrent Convertible Notes Offering. As a result of both of these roles, such underwriters and/or such affiliates have received, or may in the future, receive customary fees and commissions for such transactions. Merrill Lynch, Pierce, Fenner & Smith Incorporated and J.P. Morgan Securities LLC are also each acting as dealer-managers in connection with the 2024 Tender Offer and as a result, will be receiving customary fees for such role. In addition, concurrently with this offering, we expect to repurchase shares of our common stock in privately negotiated transactions effected with or through J.P. Morgan Securities LLC, one of the Representatives of this offering, and, as a result, J.P. Morgan Securities LLC may receive customary fees for such role.

In addition, in the ordinary course of their business activities, the underwriters and their affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers. Such investments and securities activities may involve securities and/or instruments of ours or our affiliates. The underwriters and their affiliates may also make investment recommendations and/or publish or express independent research views in respect of such securities or financial instruments and may hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

If any of the underwriters or their affiliates has a lending relationship with us, certain of those underwriters or their affiliates routinely hedge, and certain other of those underwriters or their affiliates may hedge, their credit exposure to us consistent with their customary risk management policies. Typically, these underwriters and their affiliates would hedge such exposure by entering into transactions which consist of either the purchase of credit default swaps or the creation of short positions in our securities, including potentially the notes offered hereby. Any such credit default swaps or short positions could adversely affect future trading prices of the notes offered hereby.
