RISK FACTORS

Investing in the New Notes involves risk. In addition to the other information included or incorporated by reference in this prospectus, including the matters addressed under “Cautionary Statement Regarding Forward-Looking Statements,” you should carefully consider the risks and uncertainties described below, as well as the risks discussed in our public filings with the SEC (including under the heading “Risk Factors” in the Quarterly Report on Form 10-Q), before deciding to participate in the Exchange Offer and to invest in the New Notes. The risks and uncertainties described below and incorporated by reference into this prospectus are not the only ones related to our business, the Exchange Offer or the New Notes. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also materially and adversely affect our business operations, results of operations, financial condition, liquidity or prospects. The trading price of the New Notes could decline due to the materialization of any of these risks, and you may lose all or part of your original investment in the New Notes.

Risks Relating to Our Indebtedness and the New Notes

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 senior secured notes due 2023 (the “Secured Notes”) and $3,350.0 million in the Old Notes. We also entered into new senior credit facilities on April 29, 2016 (the “Credit Facilities”) under which we had $8.1billion aggregate principal amount outstanding as of September 30, 2016. As of September 30, 2016, we had $13.4 billion aggregate principal amount of total indebtedness and we had $1.0 billion of additional borrowing availability under our revolving credit facility. The proceeds from the notes issuance 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 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.

10

Table of Contents

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

As of September 30, 2016, we had $13.4 billion aggregate principal amount of total indebtedness and we had $1.0 billion of additional borrowing availability under our revolving credit facility. 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.

The agreements that govern our indebtedness 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:

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 or repay the

11

Table of Contents

Secured Notes and the New 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 or the Secured Notes and the New 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 the Secured Notes, 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 the Secured Notes and the New Notes, we, including our subsidiaries, have the ability to incur significant additional indebtedness. As of September 30, 2016, we had:

Although the terms of the Credit Facilities and the indentures governing the Secured Notes and the New 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. If we incur significant additional indebtedness, the related risks that we face could increase.

The New Notes will be our senior unsecured obligations, and the related guarantees will be unsecured obligations of the guarantors. As such, the New 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 the Secured Notes.

Our obligations under the New Notes and the guarantors’ obligations under the guarantees will not be secured. The New Notes will be effectively subordinated to our and our guarantors’ existing and any future secured indebtedness, including the Credit Facilities and the Secured Notes, 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 30, 2016, we and our guarantors had approximately $10.0 billion aggregate principal amount of secured indebtedness outstanding and $1.0 billion available under the Revolving Facility. If we are involved in any dissolution, liquidation or reorganization, or if we default under the indenture governing the New Notes, holders of our secured debt would be paid before holders of the New Notes receive any amounts due under the New Notes to the extent of the value of the collateral securing such indebtedness. In that event, holders of the New Notes may not be able to recover any or all of the principal or interest due under the New Notes.

12

Table of Contents

In the event that we are declared bankrupt, become insolvent or are liquidated or reorganized or if we default under the Credit Facilities or the Secured Notes, the lenders could foreclose on the pledged assets to the exclusion of holders of the New Notes, even if an event of default exists under the indenture governing the New Notes at such time. Furthermore, if the lenders foreclose upon and sell the pledged equity interests in any guarantor of the New Notes, then that guarantor will be released from its guarantee of the New Notes automatically and immediately upon such sale. In any such event, because the New 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 New Notes will be structurally subordinated to all indebtedness of our existing subsidiaries that are not guarantors of the New Notes and our future subsidiaries that do not become guarantors of the New Notes.

The New 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 New 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 New Notes. As of September 30, 2016, our non-guarantor subsidiaries had $3.0 billion of aggregate total liabilities (excluding intercompany transactions), all of which would have been structurally senior to the New Notes and the related guarantees.

In addition, the indenture governing the New 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, which will cause those guarantors to be released from their guarantees of the New Notes.

So long as any obligations under our Credit Facilities remain outstanding, any guarantee of the New Notes may be released without action by, or consent of, any holder of New Notes or the trustee under the indenture governing the New 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. Any of our subsidiaries that are released as guarantors of the Credit Facilities will automatically be released as guarantors of the New Notes. You will not have a claim as a creditor against any subsidiary that is no longer a guarantor of the New 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 New Notes.

Under certain circumstances a court could cancel the New Notes or the related guarantees under fraudulent conveyance laws. If that occurs, you may not receive any payments on the New Notes.

Federal and state fraudulent transfer and conveyance statutes may apply to the issuance of the New 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 New Notes or guarantees could be voided as a fraudulent transfer or conveyance if we or any of the guarantors, as applicable: (1) issued the New 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 New Notes or incurring the guarantees and, in the case of (2) only, one of the following is also true at the time thereof:

13

Table of Contents

If a court were to find that the issuance of the New Notes or the incurrence of the guarantees was a fraudulent transfer or conveyance, the court could void the payment obligations under the New Notes or such guarantee or subordinate the New Notes or such guarantee to presently existing and future indebtedness of ours or of the related guarantor, or require the holders of the New 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 New Notes. Further, the voidance of the New 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 New 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:

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 New Notes.

The indenture governing the New 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.

Table of Contents

Repayment of our indebtedness, including the New 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 New 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 New Notes, our subsidiaries do not have any obligation to pay amounts due on the New 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 New 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 New 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 New Notes.

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

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

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 New Notes. The market for the New 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 New Notes.

Upon the occurrence of a “change of control,” as defined in the indenture governing the New Notes, we must offer to buy back the New 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 New Notes would be a default under the indenture governing the New Notes. See “Description of the Notes—Change of Control”.

Furthermore, certain change of control 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

15

Table of Contents

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 New Notes. We cannot assure you that we will have available funds sufficient to repurchase the New 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 New 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 New Notes includes a phrase relating to the sale, assignment, conveyance, transfer or other disposition of “all or substantially all” of our and our subsidiaries’ 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 New Notes may require us to make an offer to repurchase the New 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 New Notes, or the trading market for the New Notes, to the extent a trading market for the New 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 New Notes.

If the Notes become rated investment grade at any time by two of S&P, Moody’s or Fitch, certain covenants included in the indenture will be suspended, and the holders of the New Notes will lose the protection of these covenants.

The indenture for the New Notes includes certain covenants that will be suspended and cease to have any effect from and after the first date when the New Notes are rated investment grade by two of S&P, Moody’s or Fitch. See “Description of the Notes—Certain Covenants—Suspension of Covenants.” These covenants restrict, among other things, our ability to pay dividends, incur additional debt and to enter into certain types of transactions. Because we would not be subject to these restrictions at any time that the New Notes are rated investment grade, we would be able to make dividends and distributions and incur substantial additional debt without satisfying the terms of the suspended covenants. If after these covenants are suspended, two of S&P, Moody’s or Fitch were to downgrade their ratings of the New Notes to a non-investment grade level, the covenants would be reinstated and the holders of the New Notes would again have the protection of these covenants. However, any indebtedness incurred or other transactions entered into during such time as the New Notes were rated investment grade would be permitted.

Risks Relating to the Exchange Offer

The consummation of the Exchange Offer may not occur.

We are not obligated to complete the Exchange Offer under certain circumstances. See “Description of the Exchange Offer—Conditions to the Exchange Offer.” Even if the Exchange Offer is completed, it may not be completed on the schedule described in this prospectus. Accordingly, holders participating in the Exchange Offer may have to wait longer than expected to receive their New Notes, during which time those holders of the Old Notes will not be able to effect transfers of their Old Notes tendered in the Exchange Offer.

16

Table of Contents

You may be required to deliver prospectuses and comply with other requirements in connection with any resale of the New Notes.

If you tender your Old Notes for the purpose of participating in a distribution of the New Notes, you will be required to comply with the registration and prospectus delivery requirements of the Securities Act in connection with any resale of the New Notes. In addition, if you are a broker-dealer that receives the New Notes for your own account in exchange for the Old Notes that you acquired as a result of market-making activities or any other trading activities, you will be required to acknowledge that you will deliver a prospectus in connection with any resale of such New Notes.

Late deliveries of Old Notes or any other failure to comply with the Exchange Offer procedures could prevent a holder from exchanging its Old Notes.

Holders are responsible for complying with all procedures related to the Exchange Offer. The issuance of New Notes in exchange for Old Notes will only occur upon proper completion of the procedures described in this prospectus under “The Exchange Offer.” Therefore, holders of Old Notes that wish to exchange them for New Notes should allow sufficient time for timely completion of the exchange procedure. Neither we nor the exchange agent are obligated to extend the Exchange Offer or notify you of any failure to follow the proper procedure.

Failure to tender the Old Notes in the Exchange Offer may affect their marketability and will substantially limit, and may effectively eliminate, opportunities to sell your Old Notes in the future.

If the Old Notes are tendered and accepted in the Exchange Offer, the trading market, if any, for the untendered and tendered but unaccepted Old Notes will be adversely affected. Your failure to participate in the Exchange Offer will substantially limit, and may effectively eliminate, opportunities to sell your Old Notes in the future.

We issued the Old Notes in a private placement exempt from the registration requirements of the Securities Act. Accordingly, you may not offer, sell or otherwise transfer your Old Notes except in compliance with the registration requirements of the Securities Act and any other applicable securities laws, or pursuant to an exemption from the securities laws, or in a transaction not subject to the securities laws. If you do not exchange your Old Notes for the New Notes in the Exchange Offer, your Old Notes will continue to be subject to these transfer restrictions after the completion of the Exchange Offer. In addition, after the completion of the Exchange Offer, you will no longer be able to obligate us to register the Old Notes under the Securities Act.

DESCRIPTION OF THE EXCHANGE OFFER

Purpose of the Exchange Offer

On April 13, 2016, we issued $3,350.0 million aggregate principal amount of the Old Notes. In connection with that issuance, we entered into the Registration Rights Agreement on April 13, 2016. Pursuant to the Registration Rights Agreement, Western Digital and the guarantors agreed that they will, at their expense, for the benefit of the holders of the Old Notes use commercially reasonable efforts to:

Upon the effectiveness of the registration statement of which this prospectus is a part, we will offer the New Notes in exchange for the Old Notes. We filed a copy of the Registration Rights Agreement as an exhibit incorporated by reference into the registration statement.

Resale of the New Notes

We are making the Exchange Offer in reliance on the position of the staff of the SEC as set forth in interpretive letters addressed to other parties in other transactions. For further information on the SEC’s position, see Exxon Capital Holdings Corporation, available May 13, 1988, Morgan Stanley & Co. Incorporated, available June 5, 1991 and Shearman & Sterling, available July 2, 1993, and other interpretive letters to similar effect. We have not sought our own interpretive letter, however, and we cannot assure you that the staff would make a similar determination with respect to the Exchange Offer as it has in interpretive letters to other parties. Based on these interpretations by the staff, we believe that the New Notes issued under the Exchange Offer may be offered for resale, resold or otherwise transferred by you, without further compliance with the registration and prospectus delivery provisions of the Securities Act, so long as you:

By tendering the Old Notes in exchange for the New Notes, you will be required to represent to us that each of the above statements applies to you. If you are participating in or intend to participate in, a distribution of the New Notes, or have any arrangement or understanding with any person to participate in a distribution of the New Notes to be acquired in this Exchange Offer, you may be deemed to have received restricted securities and may not rely on the applicable interpretations of the staff of the SEC. If you are so deemed, you will have to comply with the registration and prospectus delivery requirements of the Securities Act in connection with any secondary resale transaction.

Each broker-dealer that receives the New Notes for its own account in exchange for the Old Notes, where the Old Notes were acquired by the broker-dealer as a result of market-making activities or other trading activities, must acknowledge that it will deliver a prospectus in connection with any resale of the New Notes. The letter of transmittal states that by so acknowledging and by delivering a prospectus, a broker-dealer will not be

20

Table of Contents

deemed to admit that it is an “underwriter” within the meaning of the Securities Act. A broker-dealer may use this prospectus, as it may be amended or supplemented from time to time, in connection with resales of the New Notes received in exchange for the Old Notes which the broker-dealer acquired as a result of market-making or other trading activities. See “Plan of Distribution.”

The Exchange Offer is not being made to, nor will we accept tenders for exchange from, holders of the Old Notes in any jurisdiction in which the Exchange Offer or the acceptance of it would not be in compliance with the securities or blue sky laws of such jurisdiction.

Terms of the Exchange Offer

Upon the terms and subject to the conditions set forth in this prospectus and the letter of transmittal, we will accept any and all Old Notes validly tendered and not validly withdrawn prior to the Expiration Date.

We will not pay any accrued and unpaid interest on the Old Notes that we acquire in the Exchange Offer. Instead, interest on the New Notes will accrue from the later of (i) the last interest payment date on which interest was paid on the Old Note surrendered in exchange for the New Note or (ii) if the Old Note is surrendered for exchange on a date in a period that includes the record date for an interest payment date to occur on or after the date of such exchange and as to which interest will be paid, the date of such interest payment date.

Tendering holders of the Old Notes must tender the Old Notes in minimum denominations of $2,000, and integral multiples of $1,000 in excess thereof. The New Notes will be issued in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof.

The terms of the New Notes are identical in all material respects to the terms of the Old Notes, except that:

The New Notes will evidence the same debt as the Old Notes. The New Notes will be issued under the same indenture and will be entitled to the same benefits under the indenture as the Old Notes being exchanged. As of the date of this prospectus, $3,350.0 million aggregate principal amount of the Old Notes are outstanding. The Old Notes accepted for exchange will be retired and cancelled and not reissued.

Except as described under “Form, Book-Entry Procedures and Transfer,” we will issue the New Notes in the form of one or more global notes registered in the name of DTC or its nominee, and each beneficial owner’s interest in it will be transferable in book-entry form through DTC.

We will conduct the Exchange Offer in accordance with the applicable requirements of the Securities Act and the Exchange Act, and the rules and regulations of the SEC thereunder.

We will be considered to have accepted validly tendered Old Notes if and when we have given oral or written notice to that effect to the exchange agent. The exchange agent will act as agent for the tendering holders for the purposes of receiving the New Notes from us.

If we do not accept any tendered Old Notes for exchange because of an invalid tender, the occurrence of the other events described in this prospectus or otherwise, we will return these Old Notes, without expense, to the tendering holder as soon as practicable after the Expiration Date of the Exchange Offer.

21

Table of Contents

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

If we successfully complete the Exchange Offer, any Old Notes which holders do not tender or which we do not accept in the Exchange Offer will remain outstanding and continue to accrue interest. The holders of the Old Notes after the Exchange Offer in general will not have further rights under the Registration Rights Agreement, including registration rights and any rights to additional interest. Holders wishing to transfer the Old Notes would have to rely on exemptions from the registration requirements of the Securities Act.

Expiration Date; Extensions; Amendments; Termination

For purposes of the Exchange Offer, the term “Expiration Date” means 5:00 p.m., New York City time, on February 6, 2017, subject to our right to extend that time and date in our sole discretion, in which case the Expiration Date means the latest time and date to which the Exchange Offer is extended.

We reserve the right, in our sole discretion, by giving oral or written notice to the exchange agent, to:

If the Exchange Offer is amended in a manner that we determine constitutes a material change, we will extend the Exchange Offer for a period of two to ten business days, depending upon the significance of the amendment and the manner of disclosure to the holders, if the Exchange Offer would otherwise have expired during that two to ten business day period.

We will notify holders of the Old Notes of any extension, amendment or termination of the Exchange Offer by press release or other public announcement. We will announce any extension of the Expiration Date no later than 9:00 a.m., New York City time, on the first business day after the previously scheduled Expiration Date. We have no other obligation to publish, advertise or otherwise communicate any information about any extension, amendment or termination.

Settlement Date

We will deliver the New Notes on the settlement date, which will be as soon as practicable after the Expiration Date of the Exchange Offer. We will not be obligated to deliver the New Notes unless the Exchange Offer is consummated.

Conditions to the Exchange Offer

Notwithstanding any other provision of the Exchange Offer, we will not be required to accept for exchange, or to issue the New Notes in exchange for, any Old Notes and may terminate or amend the Exchange Offer if at any time before the expiration of the Exchange Offer, we determine (i) that the Exchange Offer violates applicable law, any applicable interpretation of the staff of the SEC or any order of any governmental agency or court of competent jurisdiction; (ii) an action or proceeding shall have been instituted or threatened in any court or by any governmental agency which might materially impair our ability to proceed with the Exchange Offer or a material adverse development shall have occurred in any existing action or proceeding with respect to us; or (iii) all governmental approvals that we deem necessary for the consummation of the Exchange Offer have not been obtained.

22

Table of Contents

Other than the federal securities laws, there are no federal or state regulatory requirements that we must comply with and there are no approvals that we must obtain in connection with the Exchange Offer.

The foregoing conditions are for our sole benefit and may be asserted by us regardless of the circumstances giving rise to any such condition or may be waived by us in whole or in part at any time and from time to time. The failure by us at any time to exercise any of the foregoing rights shall not be deemed a waiver of any of those rights and each of those rights shall be deemed an ongoing right which may be asserted at any time and from time to time. Any determination made by us concerning an event, development or circumstance described or referred to above will be conclusive and binding.

If any of the foregoing conditions are not satisfied, we may, at any time on or prior to the Expiration Date:

In addition, we will not accept for exchange any Old Notes tendered, and no New Notes will be issued in exchange for those Old Notes, if at such time any stop order shall be threatened or in effect with respect to the registration statement of which this prospectus constitutes a part or with respect to the qualification of the indenture governing the New Notes under the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”).

Effect of Tender

Any tender by a holder, and our subsequent acceptance of that tender, of the Old Notes will constitute a binding agreement between that holder and us upon the terms and subject to the conditions of the Exchange Offer described in this prospectus and in the letter of transmittal. The acceptance of the Exchange Offer by a tendering holder of the Old Notes will constitute the agreement by that holder to deliver good and marketable title to the tendered Old Notes, free and clear of any and all liens, restrictions, charges, pledges, security interests, encumbrances or rights of any kind of third parties.

Letter of Transmittal; Representations, Warranties and Covenants of Holders of Old Notes

Upon agreement to the terms of the letter of transmittal pursuant to an agent’s message, a holder, or the beneficial holder of the Old Notes on behalf of which the holder has tendered, will, subject to that holder’s ability to withdraw its tender, and subject to the terms and conditions of the Exchange Offer generally, thereby:

23

Table of Contents

In addition, by tendering the Old Notes in the Exchange Offer, each holder of the Old Notes will represent, warrant and agree that:

The representations, warranties and agreements of a holder tendering the Old Notes will be deemed to be repeated and reconfirmed on and as of the Expiration Date and the settlement date. For purposes of this prospectus, the “beneficial owner” of any Old Notes means any holder that exercises investment discretion with respect to those Old Notes.

Absence of Dissenters’ Rights

Holders of the Old Notes do not have any appraisal or dissenters’ rights in connection with the Exchange Offer.

Acceptance of Old Notes for Exchange and Delivery of New Notes

On the settlement date, the New Notes to be issued in exchange for the Old Notes in the Exchange Offer, if consummated, will be delivered in book-entry form.

We will be deemed to accept validly tendered Old Notes that have not been validly withdrawn as provided in this prospectus when, and if, we give oral or written notice of acceptance to the exchange agent. Subject to the terms and conditions of the Exchange Offer, delivery of the New Notes will be made by the exchange agent on the settlement date following receipt of that notice. The exchange agent will act as agent for tendering holders of the Old Notes for the purpose of receiving the Old Notes and transmitting the New Notes as of the settlement date. If any tendered Old Notes are not accepted for any reason described in the terms and conditions of the Exchange Offer, such unaccepted Old Notes will be returned without expense to the tendering holders as promptly as practicable after the expiration or termination of the Exchange Offer.

Procedures for Tendering

To participate in the Exchange Offer, you must properly tender your Old Notes to the exchange agent as described below. We will only issue the New Notes in exchange for the Old Notes that you timely and properly tender. Therefore, you should allow sufficient time to ensure timely delivery of the Old Notes, and you should follow carefully the instructions on how to tender your Old Notes. It is your responsibility to properly tender your Old Notes. We have the right to waive any defects. However, we are not required to waive defects, and none of us, the exchange agent, the trustee or any other person is required to notify you of defects in your tender.

If you have any questions or need help in exchanging your Old Notes, please contact the exchange agent at the address or telephone numbers set forth below.

All of the Old Notes were issued in book-entry form, and all of the Old Notes are currently represented by global certificates registered in the name of Cede & Co., the nominee of DTC. We have confirmed with DTC that the Old Notes may be tendered using DTC’s automatic tender offer program (“ATOP”). The exchange agent will establish an account with DTC for purposes of the Exchange Offer promptly after the commencement of the Exchange Offer, and DTC participants may electronically transmit their acceptance of the Exchange Offer by causing DTC to transfer their Old Notes to the exchange agent using the ATOP procedures. In connection with the transfer, DTC will send an “agent’s message” to the exchange agent. The agent’s message will state that DTC has received instructions from the participant to tender the Old Notes and that the participant agrees to be bound by the terms of the letter of transmittal.

By using the ATOP procedures to exchange the Old Notes, you will not be required to deliver a letter of transmittal to the exchange agent. However, you will be bound by its terms just as if you had signed it.

Determinations Under the Exchange Offer. We will determine in our sole discretion all questions as to the validity, form, eligibility, time of receipt, acceptance of tendered Old Notes and withdrawal of tendered Old Notes. Our determination will be final and binding. We reserve the absolute right to reject any Old Notes not properly tendered or any Old Notes our acceptance of which would, in the opinion of our counsel, be unlawful. We also reserve the right to waive any defect, irregularities or conditions of tender as to particular Old Notes. Our interpretation of the terms and conditions of the Exchange Offer, including the instructions in the letter of transmittal, will be final and binding on all parties. Unless waived, all defects or irregularities in connection with tenders of the Old Notes must be cured within such time as we shall determine. Although we intend to notify

25

Table of Contents

holders of defects or irregularities with respect to tenders of the Old Notes, none of us, the exchange agent, the trustee or any other person will incur any liability for failure to give such notification. Tenders of the Old Notes will not be deemed made until such defects or irregularities have been cured or waived. Any Old Notes received by the exchange agent that are not properly tendered and as to which the defects or irregularities have not been cured or waived will be returned to the tendering holder as soon as practicable after the Expiration Date of the exchange.

When We Will Issue the New Notes. In all cases, we will issue the New Notes for the Old Notes that we have accepted for exchange under the Exchange Offer only after the exchange agent receives, prior to the Expiration Date:

Return of the Old Notes Not Accepted or Exchanged. If we do not accept any tendered Old Notes for exchange or if the Old Notes are submitted for a greater principal amount than the holder desires to exchange, the unaccepted or non-exchanged Old Notes will be returned without expense to their tendering holder. Such non-exchanged Old Notes will be credited to an account maintained with DTC. These actions will occur as promptly as practicable after the expiration or termination of the Exchange Offer.

Participating Broker-Dealers. Each broker-dealer that receives the New Notes for its own account in exchange for the Old Notes, where those Old Notes were acquired by such broker-dealer as a result of market-making activities or other trading activities, must acknowledge that it will deliver a prospectus in connection with any resale of those New Notes. See “Plan of Distribution.”

Withdrawal of Tenders

Tenders of the Old Notes may be withdrawn at any time prior to the Expiration Date.

For a withdrawal to be effective, you must comply with the appropriate ATOP procedures. Any notice of withdrawal must specify the name and number of the account at DTC to be credited with withdrawn Old Notes and otherwise comply with the ATOP procedures.

We will determine all questions as to the validity, form, eligibility and time of receipt of a notice of withdrawal. Our determination shall be final and binding on all parties. We will deem any Old Notes so withdrawn not to have been validly tendered for exchange for purposes of the Exchange Offer.

Any Old Notes that have been tendered for exchange but that are not exchanged for any reason will be credited to an account maintained with DTC for the Old Notes. This return or crediting will take place as soon as practicable after withdrawal, rejection of tender, expiration or termination of the Exchange Offer. You may retender properly withdrawn Old Notes by following the procedures described under “—Procedures for Tendering” above at any time on or prior to the Expiration Date of the Exchange Offer.

We may make any announcement required pursuant to the terms of this prospectus or required by the Exchange Act or the rules promulgated thereunder through a reasonable press release or other public announcement in our sole discretion; provided, that, if any such announcement is made by issuing a press release to Business Wire, PR Newswire or Dow Jones News Service, such announcement shall be reasonable and sufficient.

Other Fees and Expenses

We will bear the expenses of soliciting tenders of the Old Notes. The principal solicitation is being made by mail. Additional solicitations may, however, be made by e-mail, facsimile transmission, telephone or in person by the exchange agent as well as our officers and other employees and those of our affiliates.

However, we will pay the exchange agent reasonable and customary fees for its services and will reimburse it for its reasonable out-of-pocket expenses.

Tendering holders of the Old Notes will not be required to pay any fee or commission to the exchange agent. If, however, a tendering holder handles the transaction through its commercial bank, broker, dealer, trust company or other institution, that holder may be required to pay brokerage fees or commissions.

Accounting Treatment

The New Notes will be recorded at the same carrying value as the Old Notes as reflected in our accounting records on the settlement date for the Exchange Offer. Accordingly, we will not recognize any gain or loss for accounting purposes upon the consummation of the Exchange Offer.

27

Table of Contents

name of, or request that the Old Notes not tendered or not accepted in the Exchange Offer be returned to, a person other than the registered tendering holder will be responsible for the payment of any applicable transfer tax on those Old Notes.

Consequences of Failure to Exchange

Holders of the Old Notes who do not exchange their Old Notes for the New Notes under this Exchange Offer will remain subject to the restrictions on transfer applicable in the Old Notes as set forth in the legend printed on the Old Notes as a consequence of the issuance of the Old Notes pursuant to exemptions from, or in transactions not subject to, the registration requirements of the Securities Act and applicable state securities laws.

Any Old Notes not tendered by their holders in exchange for the New Notes in this Exchange Offer will not retain any rights under the Registration Rights Agreement (except in certain limited circumstances) or any rights to additional interest. See “—Resale Registration Statement; Additional Interest.”

In general, you may not offer or sell the Old Notes unless they are registered under the Securities Act, or if the offer or sale is exempt from the registration requirements of the Securities Act and applicable state securities laws. We do not intend to register resales of the Old Notes under the Securities Act. Based on interpretations of the SEC staff, the New Notes issued pursuant to this Exchange Offer may be offered for resale, resold or otherwise transferred by their holders (other than any such holder that is our “affiliate” within the meaning of Rule 405 under the Securities Act) without compliance with the registration and prospectus delivery provisions of the Securities Act, provided that the holders acquired the New Notes in the ordinary course of business and the holders are not engaged in, have no arrangement with any person to participate in, and do not intend to engage in, any public distribution of the New Notes to be acquired in this Exchange Offer. Any holder who tenders in this Exchange Offer and is engaged in, has an arrangement with any person to participate in, or intends to engage in, any public distribution of the New Notes (i) may not rely on the applicable interpretations of the SEC and (ii) must comply with the registration and prospectus delivery requirements of the Securities Act in connection with a secondary resale transaction.

Resale Registration Statement; Additional Interest

Under the Registration Rights Agreement, in the event that:

then, we shall use our commercially reasonable efforts to cause to be filed as soon as practicable after such determination, date or Shelf Request, as the case may be, a shelf registration statement on an appropriate form under Rule 415 of the Securities Act, which may be an amendment to the Exchange Offer Registration Statement (in either event, the “Shelf Registration Statement”), providing for the sale of all the Old Notes by the holders thereof and to have such Shelf Registration Statement become effective.

We will use our commercially reasonable efforts to keep such Shelf Registration Statement continuously effective, supplemented and amended to the extent necessary to ensure that it is available for resales of the New Notes by the holders, until the earlier to occur of (i) one year following the date when the Shelf Registration Statement has been declared effective by the SEC (the “Shelf Effectiveness Period”) and (ii) all the Old Notes covered by such Shelf Registration Statement having been sold pursuant to such Shelf Registration Statement.

28

Table of Contents

The Registration Rights Agreement further provides that in the event that (i) we have not completed the Exchange Offer on or prior to the 365th day after April 13, 2016, (ii) the Shelf Registration Statement, if required, has not been declared effective by the SEC on or prior to the 365th day after April 13, 2016, (iii) the Shelf Registration Statement, if required, has become effective and thereafter ceases to be effective or the prospectus therein ceases to be usable at any time during the Shelf Effectiveness Period, and such failure to remain effective or usable exists for more than 45 days (whether or not consecutive) in any 12-month period or (iv) the Shelf Registration Statement, if required, has become effective and thereafter, on more than two occasions in any 12-month period during the Shelf Effectiveness Period, ceases to be effective or the prospectus contained therein ceases to be usable (each such event, a “Registration Default”), then the interest rate borne by the Old Notes will be increased by (a) 0.25% per annum for the first 90-day period beginning on the day immediately following such Registration Default and (b) an additional 0.25% per annum with respect to each subsequent 90-day period, up to a maximum increase of 1.00% per annum.

Participation in this Exchange Offer is voluntary, and you should carefully consider whether to participate. You are urged to consult your financial and tax advisors in making your own decision as to what action to take.

DESCRIPTION OF THE NOTES

Certain terms used in this description are defined under the subheading “—Certain Definitions.” In this description, (i) the terms “Issuer”, “we,” “our” and “us” each refer to Western Digital Corporation and not to any of its consolidated subsidiaries and (ii) the term “Notes” refers to the New Notes and the Old Notes, together.

On April 13, 2016, the Issuer issued $3,350,000,000 aggregate principal amount of the Old Notes under an indenture dated as of April 13, 2016 (the “Indenture”) among the Issuer, the Guarantors and U.S. Bank National Association, as trustee (the “Trustee”). The Old Notes were issued in a private transaction that was not subject to the registration requirements of the Securities Act.

The Issuer will issue up to $3,350,000,000 aggregate principal amount of the New Notes under the Indenture in exchange for the Old Notes. The terms of the New Notes are substantially identical to the terms of the Old Notes, except that the New Notes will be registered under the Securities Act, and the transfer restrictions and registration rights and related additional interest provisions applicable to the Old Notes will not apply to the New Notes.

The following description is only a summary of the material provisions of the Notes and the Indenture, does not purport to be complete and is qualified in its entirety by reference to the provisions of the Indenture and the Notes, including the definitions therein of certain terms used below and those made part thereof by reference to the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”). We urge you to read the Indenture in its entirety 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 “Incorporation of Certain Information by Reference.”

Brief Description of the Notes

The Notes will be senior obligations of the Issuer. The Notes will be guaranteed by each of the Issuer’s wholly-owned domestic Restricted Subsidiaries that is required to provide a guarantee under the Credit Agreement (collectively, the “Guarantors”). The Notes and the guarantees:

Principal, Maturity and Interest

The Issuer will issue the Notes initially with an aggregate principal amount of $3,350 million. The Issuer will issue the Notes in minimum denominations of $2,000 and any integral multiple of $1,000 in excess thereof. The Notes will mature on April 1, 2024. Subject to our compliance with the covenant described under the subheading “—Certain Covenants—Limitation on Indebtedness,” we are permitted to issue more Notes from time to time (the “Additional Notes”). The Notes and the Additional Notes, if any, will be treated as a single class

30

Table of Contents

for all purposes of the Indenture, including waivers, amendments, redemptions and offers to purchase; provided, however, that in the event that any Additional Notes are not fungible with the Notes for U.S. federal income tax purposes, such nonfungible Additional Notes will be issued with a separate CUSIP or ISIN number so that they are distinguishable from the Notes. Unless the context otherwise requires, for all purposes of the Indenture and this “Description of the Notes,” references to the Notes include any Additional Notes actually issued.

Interest on the New Notes will accrue at the rate of 10.500% per annum and will be payable semiannually in arrears on April 1 and October 1, commencing on April 1, 2017. The Issuer will make each interest payment to the Holders of record on the immediately preceding March 15 and September 15. If a payment date is on a Legal Holiday, payment will be made on the next succeeding Business Day and no interest shall accrue for the intervening period.

Interest on the New Notes will accrue from the later of (i) the last interest payment date on which interest was paid on the Old Note surrendered in exchange for the New Note or (ii) if the Old Note is surrendered for exchange on a date in a period that includes the record date for an interest payment date to occur on or after the date of such exchange and as to which interest will be paid, the date of such interest payment date. 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 prior to April 1, 2019.

On and after April 1, 2019, we will be entitled at our option on one or more occasions to redeem all or a portion of the Notes upon not less than 30 nor more than 60 days’ notice, at the redemption prices (expressed in percentages of principal amount on the redemption date), plus accrued and unpaid interest to, but excluding, the redemption date (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date), if redeemed during the 12-month period commencing on April 1 of the years set forth below:

In addition, any time prior to April 1, 2019, we will be entitled at our option on one or more occasions to redeem the Notes (which includes Additional Notes, if any) in an aggregate principal amount not to exceed 35% of the aggregate principal amount of the Notes and the Additional Notes (at a redemption price (expressed as a percentage of principal amount) of 110.500%, plus accrued and unpaid interest to, but excluding, the redemption date (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date), with the net cash proceeds from one or more Qualified Equity Offerings; provided, however, that

Prior to April 1, 2019, 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 to be redeemed plus the Applicable Premium as of, and accrued and unpaid interest to, but excluding, the redemption date (subject to the right of

31

Table of Contents

Holders of record on the relevant record date to receive interest due on the relevant interest payment date). Notice of such redemption must be mailed by first class mail to each Holder’s registered address (or sent electronically in accordance with the applicable procedures of the depositary in the case of global Notes), not less than 30 nor more than 60 days prior to the redemption date.

Selection and notice of redemption

If we are redeeming less than all of the Notes at any time, the Trustee will select Notes on a pro rata basis to the extent practicable or in such manner as it shall deem fair and appropriate, unless another method is required by law or applicable exchange or depositary requirements.

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 at least 30 but not more than 60 days before the redemption date to each Holder of Notes to be redeemed at its registered address (or sent electronically in accordance with the applicable procedures of the depositary in the case of global Notes), except that redemption notices may be sent more than 60 days prior to the redemption date if the notice is issued in connection with a defeasance of Notes or a satisfaction and discharge of the Indenture. Any inadvertent defect in the notice of redemption, including an inadvertent failure to give notice, to any Holder selected for redemption will not impair or affect the validity of the redemption of any other Note redeemed in accordance with provisions of the Indenture.

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. We will issue a new Note in a principal amount equal to the unredeemed portion of the original Note in the name of the Holder upon cancellation of the original Note; provided that new Notes will only be issued in minimum denominations of $2,000 and integral multiples of $1,000 in excess of $2,000. Notes called for redemption become due on the date fixed for redemption. Notes held in certificated form must be surrendered to the paying agent in order to collect the redemption price. Unless the Issuer defaults in the payment of the redemption price, on and after the redemption date, interest ceases to accrue on Notes or portions of them called for redemption.

Notice of any redemption, whether in connection with a Qualified Equity Offering or otherwise, may, at the Issuer’s discretion, be subject to one or more conditions precedent, including, but not limited to, the completion of a Qualified Equity Offering or other financing or of a transaction resulting in a Change of Control. In the event that the relevant conditions precedent are not satisfied as of the date specified for redemption in any such notice (or amendment thereto), the Issuer may, in its discretion, rescind such notice or amend it to specify another redemption date.

Mandatory redemption; offers to purchase; open market purchases

We are not required to make any mandatory redemption or sinking fund payments with respect to the Notes. However, under certain circumstances, we may be required to offer to purchase Notes as described under “—Change of Control” and “—Certain Covenants—Limitation on Sales of Assets and Subsidiary Stock.” We may at any time and from time to time purchase Notes in the open market or otherwise.

Subsidiary Guarantees

The Notes will be guaranteed by the Guarantors. Each of the Guarantors will jointly and severally guarantee, on a senior unsecured basis, obligations under the Notes. The obligations of each Guarantor under its Subsidiary Guarantee are designed to be limited as necessary to prevent that Subsidiary Guarantee from constituting a fraudulent conveyance under applicable law, and, therefore, such Subsidiary Guarantee is specifically limited to an amount that such Guarantor could guarantee without such Subsidiary Guarantee constituting a fraudulent conveyance. This limitation, however, may not be effective to prevent such Subsidiary Guarantee from constituting a fraudulent conveyance. If a Subsidiary Guarantee was rendered voidable, it could

32

Table of Contents

be subordinated by a court to all other indebtedness (including guarantees and other contingent liabilities) of the applicable Guarantor, and, depending on the amount of such indebtedness, a Guarantor’s liability on its Subsidiary Guarantee could be reduced to zero. See “Risk Factors—Risks Relating to Our Indebtedness and the New Notes—Under certain circumstances a court could cancel the New Notes or the related guarantees under fraudulent conveyance laws. If that occurs, you may not receive any payments on the New Notes.”

Each Guarantor that makes a payment under its Subsidiary 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 Subsidiary Guarantee of a Guarantor will be released upon:

Ranking

The Notes will be the senior obligations of the Issuer. The Notes will be guaranteed jointly and severally by each of the Guarantors on a senior unsecured basis. The indebtedness evidenced by the Notes and the Subsidiary Guarantees will rank pari passu in right of payment to all other Senior Indebtedness of the Issuer and the Guarantors, as the case may be, but will be effectively junior to all secured Indebtedness, including our obligations under the Secured Notes and the Credit Agreement, to the extent of the value of the assets securing such Indebtedness.

Subject to the limits described under “—Certain Covenants—Limitation on Indebtedness” and “—Certain Covenants—Limitation on Liens,” the Issuer and its Restricted Subsidiaries may Incur additional secured Indebtedness.

Virtually all of the Senior Indebtedness of the Guarantors consists of their respective guaranties of Senior Indebtedness of the Issuer under the Credit Agreement and with respect to the Secured Notes and the Notes.

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 “—Subsidiary Guarantees,” Subsidiary 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.

Although the Indenture limits the incurrence of Indebtedness and preferred stock by our Restricted Subsidiaries that are not Guarantors, such limitation is subject to a number of significant qualifications. Moreover, the Indenture does not impose any limitation on the incurrence by such Subsidiaries of liabilities that are not considered Indebtedness under the Indenture. See “—Certain Covenants—Limitation on Indebtedness.”

Change of Control

Upon the occurrence of a Change of Control, each Holder shall have the right to require that the Issuer repurchase such Holder’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 the date of purchase (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date).

Within 30 days following any Change of Control, unless we have previously or concurrently mailed a redemption notice with respect to all outstanding Notes as described under “—Optional Redemption,” we will send electronically or mail a notice by first-class mail to each Holder 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 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 such Notes validly tendered and not withdrawn under such Change of Control Offer.

34

Table of Contents

A Change of Control Offer may be made in advance of a Change of Control, conditional upon such Change of Control, if a definitive agreement is in place for the Change of Control at the time of making of the Change of Control Offer. In the event that the Change of Control has not occurred as of the purchase date for the Change of Control Offer specified in the notice therefor (or amendment thereto), the Issuer (or third party offeror) may, in its discretion, rescind such notice or amend it to specify another purchase date.

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 repurchase of Notes as a result of a Change of Control. 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 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. The Change of Control purchase feature is a result of negotiations between the Issuer and the initial purchasers. 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 Indebtedness are contained in the covenants described under “—Certain Covenants—Limitation on Indebtedness” and “—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 covenants, however, the Indenture will not contain any covenants or provisions that may afford Holders protection in the event of a highly leveraged transaction. In addition, Holders may not be entitled to require the Issuer to repurchase their Notes in certain circumstances involving a significant change in the composition of the Issuer’s board of directors, including in connection with a proxy contest, where the Issuer’s board of directors does not endorse a dissident slate of directors but approves them for purposes of the Indenture.

The Credit Agreement may prohibit or limit, and future credit agreements or other agreements to which the Issuer becomes a party may prohibit or limit, the Issuer from purchasing any Notes as a result of a Change of Control. In the event a Change of Control occurs at a time when the Issuer is prohibited from purchasing the Notes, the Issuer could seek the consent of its lenders or investors to permit the purchase of the Notes or could attempt to refinance the borrowings or securities that contain such prohibition. If the Issuer does not obtain such consent or repay such borrowings or securities, the Issuer will remain prohibited from purchasing the Notes. In such case, the Issuer’s failure to purchase tendered Notes after any applicable notice and lapse of time would constitute an Event of Default under the Indenture.

The occurrence of events that would constitute a Change of Control would constitute a default under the Credit Agreement. The indenture governing the Secured Notes may require us to repurchase the Secured Notes at the option of the holders of the Secured Notes upon a Change of Control. Future Indebtedness of the Issuer may also contain prohibitions on certain events that would constitute a Change of Control or require such Indebtedness to be repurchased upon a Change of Control. If the Issuer experiences a change of control that triggers a default under the Credit Agreement, we could seek a waiver of such default or seek to refinance the Credit Agreement. In the event we do not obtain such a waiver or refinance the Credit Agreement, such default could result in amounts outstanding under the Credit Agreement being declared due and payable. Moreover, the exercise by the Holders of their right to require us to repurchase the Notes could cause a default under such senior 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 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 repurchases.

Table of Contents

The definition of “Change of Control” includes a disposition of all or substantially all of the assets of the Issuer to any Person. 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 assets of the Issuer. As a result, it may be unclear as to whether a Change of Control has occurred and whether a Holder may require the Issuer to make an offer to repurchase the Notes as described above.

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

Certain Covenants

The Indenture contains covenants including, among others, those summarized below. During any period of time that:

the Issuer and its Restricted Subsidiaries will not be subject to the provisions of the Indenture summarized below under:

(collectively, the “Suspended Covenants”). In the event that the Issuer and the Restricted Subsidiaries are not subject to the Suspended Covenants for any period of time as a result of the preceding sentence and, subsequently, two of the Ratings Agencies rate the Notes below the required Investment Grade Ratings or a Default or Event of Default occurs and is continuing (the date of such ratings withdrawal or downgrade or the occurrence of such Default or Event of Default, the “Reversion Date”), then the Issuer and the Restricted Subsidiaries will thereafter again be subject to the Suspended Covenants for all periods after that withdrawal, downgrade, Default or Event of Default; provided that there will not be deemed to have occurred a Default or Event of Default with respect to any covenant during the time (the “Suspension Period”) that the Issuer and the Restricted Subsidiaries were not subject to the Suspended Covenants (or after that time based solely on events that occurred during that time). Calculations made after the Reversion Date of the amount available to be made as Restricted Payments under “—Limitations on Restricted Payments” will be made as though the covenant described under “—Limitation on Restricted Payments” had been in effect since the Escrow Release Date and prior to, but not during, the Suspension Period; provided that any dividend or distribution declared during the three-month period prior to any Reversion Date will be treated as though the covenant had been in effect on such date. Accordingly, other than as set forth in the immediately preceding proviso, Restricted Payments made during the Suspension Period will not reduce the amount available to be made as Restricted Payments under the first paragraph of “—Limitation on Restricted Payments.” The Issuer will give the Trustee written notice of any such suspension of covenants and in any event not later than five Business Days after such suspension has occurred. In

36

Table of Contents

the absence of such notice, the Trustee shall assume that the Suspended Covenants are in full force and effect. The Trustee has no duty to monitor the rating of the Notes or to notify Holders of the occurrence of any Suspension Period or Reversion Date.

Solely for the purpose of determining the amount of Permitted Liens under the “—Limitation on Liens” covenant during any Suspension Period and without limiting the Issuer’s or any Restricted Subsidiary’s ability to Incur Indebtedness during any Suspension Period, to the extent that calculations in the “—Limitation on Liens” covenant refer to the “—Limitation on Indebtedness” covenant, such calculations will be made as though the “—Limitation on Indebtedness” covenant remains in effect during the Suspension Period. On the Reversion Date, all Indebtedness Incurred during the Suspension Period will be classified to have been Incurred pursuant to clause (a) or one of the subclauses set forth in clause (b) of the covenant described under “—Limitation on Indebtedness” (to the extent such Indebtedness would be permitted to be Incurred thereunder as of the Reversion Date and after giving effect to the Indebtedness Incurred prior to the Suspension Period and outstanding on the Reversion Date). To the extent such Indebtedness would not be permitted to be Incurred pursuant to clause (a) or one of the subclauses set forth in clause (b) of the covenant described under “—Limitation on Indebtedness,” such Indebtedness will be deemed to have been outstanding on the Escrow Release Date, so that it is classified as permitted under subclause (b)(4) of the covenant described under “—Limitation on Indebtedness.” For purposes of determining compliance with the covenant described under “—Limitation on Sales of Assets and Subsidiary Stock,” on the Reversion Date, the Net Available Cash from all Asset Dispositions not applied in accordance with the covenant will be deemed to reset at zero. No Subsidiaries may be designated as Unrestricted Subsidiaries during any Suspension Period. The Issuer will give the Trustee written notice of any occurrence of a Reversion Date not later than five Business Days after such Reversion Date. After any such notice of the occurrence of a Reversion Date, the Trustee shall assume that the Suspended Covenants apply and are in full force and effect.

The Indenture contains covenants including, among others, the following:

Limitation on Indebtedness

(a) The Issuer will not, and will not permit any Restricted Subsidiary to, Incur, directly or indirectly, any Indebtedness; provided, however, that the Issuer and the Restricted Subsidiaries will be entitled to Incur Indebtedness if, on the date of such Incurrence and after giving effect thereto on a pro forma basis, the Consolidated Coverage Ratio would have been at least 2.00 to 1.00 (any such Indebtedness Incurred pursuant to this clause (a) being herein referred to as “Coverage Indebtedness”); provided further that the amount of Indebtedness that may be Incurred by non-Guarantor Subsidiaries under this paragraph (after giving pro forma effect to such Incurrence, including a pro forma application of the net proceeds therefrom), together with the aggregate principal amount of Indebtedness Incurred by non-Guarantor Subsidiaries pursuant to clause (5)(b) of paragraph (b) below, shall not exceed the greater of (a) $400 million and (b) 1.25% of Total Assets at any one time outstanding.

(b) Clause (a) of this covenant will not prohibit the Incurrence of the following Indebtedness (any such Indebtedness Incurred pursuant to this clause (b) being herein referred to as “Permitted Indebtedness”):

37

Table of Contents

provided, that, in the case of clause (a) and (b) on the date of any such acquisition and after giving pro forma effect thereto, either (x) the Issuer would have been entitled to Incur at least $1.00 of Coverage Indebtedness pursuant to paragraph (a) of this covenant or (y) the Consolidated

38

Coverage Ratio would have been greater than the Consolidated Coverage Ratio immediately prior to such transaction; provided further that the amount of Indebtedness that may be Incurred by non-Guarantor Subsidiaries under clause (5)(b) above (after giving pro forma effect to such Incurrence, including a pro forma application of the net proceeds therefrom), together with the aggregate principal amount of Indebtedness Incurred by non-Guarantor Subsidiaries pursuant to paragraph (a) above, shall not exceed the greater of (a) $400 million and (b) 1.25% of Total Assets at any one time outstanding;

Table of Contents

(d) For purposes of determining compliance with any U.S. dollar restriction on the Incurrence of Indebtedness where the Indebtedness Incurred is denominated in a different currency, the amount of such Indebtedness will be the U.S. Dollar Equivalent determined on the date of the Incurrence of such Indebtedness; provided, however, that if any such Indebtedness denominated in a different currency is subject to a Currency Agreement with respect to U.S. dollars covering all principal, premium, if any, and interest payable on such Indebtedness, the amount of such Indebtedness expressed in U.S. dollars will be as provided in such Currency Agreement. The principal amount of any Refinancing Indebtedness Incurred in the same currency as the Indebtedness being Refinanced will be the U.S. Dollar Equivalent, as appropriate, of the Indebtedness Refinanced, except to the extent that (1) such U.S. Dollar Equivalent was determined based on a Currency Agreement, in which case the Refinancing Indebtedness will be determined in accordance with the preceding sentence, and (2) the principal amount of the Refinancing Indebtedness exceeds the principal amount of the Indebtedness being Refinanced, in which case the U.S. Dollar Equivalent of such excess, as appropriate, will be determined on the date such Refinancing Indebtedness is Incurred; provided that the relevant U.S. Dollar Equivalent will not be deemed to be exceeded so long as the principal amount (or, if applicable, the liquidation preference, face amount, or the like) of any such new Indebtedness does not exceed the sum of the principal amount (or, if applicable, the liquidation preference, face amount, or the like) of the Indebtedness being Refinanced and the related Financing Fees.

(e) Notwithstanding any other provision of this covenant, the maximum amount of Indebtedness that the Issuer and its Restricted Subsidiaries may Incur pursuant to this covenant shall not be deemed to be exceeded, with respect to any outstanding Indebtedness, solely as a result of fluctuations in the exchange rate of currencies.

Table of Contents

The principal amount (or, if applicable, the liquidation preference, face amount, or the like) of any Indebtedness Incurred to refinance other Indebtedness, if Incurred in a different currency from the Indebtedness being refinanced, will be calculated based on the currency exchange rate applicable to the currencies in which the respective Indebtedness is denominated that is in effect on the date of the refinancing.

(f) In the case of any Refinancing of any Indebtedness Incurred under clause (b)(1), (5), (11), (14), (16), (17) or (27) above with new Indebtedness Incurred under such clause, the amount (or, if applicable, the liquidation preference, face amount, or the like) of new Indebtedness Incurred under such clause shall not be deemed to be exceeded so long as the principal amount of such new Indebtedness does not exceed the principal amount (or, if applicable, the liquidation preference, face amount, or the like) of the Indebtedness being Refinanced plus related Financing Fees.

(g) In the case of any Refinancing of any Indebtedness Incurred under clause (b)(5), (11), (14), (16) or (27) above measured by reference to a percentage of Total Assets with new Indebtedness Incurred under such clause, and the Incurrence of the relevant Indebtedness would cause the percentage of Total Assets restriction to be exceeded if calculated based on the percentage of Total Assets on the date of such Refinancing, such percentage of Total Assets restriction shall not be deemed to be exceeded so long as the principal amount of such new Indebtedness does not exceed the principal amount of the Indebtedness being Refinanced plus related Financing Fees.

(h) Notwithstanding the foregoing, the Issuer will not permit Indebtedness (other than subordinated intercompany Indebtedness) to be incurred by Western Digital International other than up to $500 million of secured or unsecured Indebtedness; provided that within ninety (90) days of the incurrence of such Indebtedness, the Issuer shall use 75% of the proceeds thereof to repay Credit Facility Indebtedness.

Limitation on Restricted Payments

(a) The Issuer will not, and will not permit any Restricted Subsidiary, directly or indirectly, to make a Restricted Payment if at the time the Issuer or such Restricted Subsidiary makes such Restricted Payment:

For purposes of determining compliance with this covenant, in the event that a Restricted Payment or Investment (or a portion thereof) meets the criteria of one or more of clauses (1) through (18) above or the definition of “Permitted Investments”, the Issuer, in its sole discretion, will classify and may later reclassify (based on circumstances existing on the date of such reclassification) such Restricted Payment or Investment (or portion thereof) between one or more of such clauses (1) through (18) and/or such clauses of the definition of “Permitted Investments” in a manner that complies with this covenant.

Limitation on Restrictions on Distributions from Restricted Subsidiaries

The Issuer will not, and will not permit any Restricted Subsidiary to, create or otherwise cause or permit to exist or become effective any consensual encumbrance or restriction on the ability of any Restricted Subsidiary to (a) pay dividends or make any other distributions on its Capital Stock to the Issuer or a Restricted Subsidiary or pay any Indebtedness owed to the Issuer or any Restricted Subsidiary, (b) make any loans or advances to the Issuer or any Restricted Subsidiary or (c) transfer any of its property or assets to the Issuer or any Restricted Subsidiary, except:

Limitation on Sales of Assets and Subsidiary Stock

The Issuer will not, and will not permit any Restricted Subsidiary to, directly or indirectly, consummate any Asset Disposition unless:

Within 365 days after the receipt of any Net Available Cash from such Asset Disposition, the Issuer or the applicable Restricted Subsidiary, as the case may be, shall apply such Net Available Cash:

49

Table of Contents

in the case of clauses (i), (ii), (iii) and (iv) other than Indebtedness owed to the Issuer or an Affiliate of the Issuer; provided that, a binding commitment to apply any Net Available Cash for purposes specified in clause (v) or (vi) above entered into in good faith by the Issuer or a Restricted Subsidiary prior to the expiration of the relevant 365-day period will extend such period by an additional 180 days to the extent of the Net Available Cash covered thereby.

Notwithstanding the foregoing provisions of this covenant, the Issuer and the Restricted Subsidiaries will not be required to apply any Net Available Cash in accordance with this covenant except to the extent that the aggregate Net Available Cash from all Asset Dispositions which is not applied in accordance with this covenant exceeds $50 million. Pending application of Net Available Cash pursuant to this covenant, such Net Available Cash may be utilized for general corporate purposes, including repayment of revolving credit borrowings.

Any Net Available Cash that is not applied or invested as provided in the preceding paragraphs will constitute “Excess Proceeds.” When the aggregate amount of Excess Proceeds exceeds $50 million, the Issuer will make an offer (an “Asset Disposition Offer”) to all Holders (with a copy to the Trustee) and, at the Issuer’s election, to holders of other Senior Indebtedness to purchase or redeem the maximum principal amount of Notes and such other Senior Indebtedness that may be purchased out of the amount of such Excess Proceeds. The offer price in any Asset Disposition Offer will be equal to 100% of the principal amount of the Notes and/or any such Senior Indebtedness plus accrued and unpaid interest to the date of purchase, and will be payable in cash in accordance with the procedures (including prorating in the event of oversubscription) set forth in the Indenture or the agreements governing the other Senior Indebtedness. If the aggregate purchase price of Indebtedness tendered exceeds the amount of Excess Proceeds, the Trustee will select the Notes and the trustee or agent for the other Senior Indebtedness shall select such other Senior Indebtedness to be purchased on a pro rata basis but in round denominations, which, in the case of the Notes, will be denominations of $2,000 principal amount or integral multiples of $1,000 in excess thereof. Upon completion of each Asset Disposition Offer, the amount of Excess Proceeds will be reset at zero and, so long as all such Notes validly tendered and not withdrawn pursuant to such offer are purchased by the Issuer in compliance with this covenant, any excess of the offer amount over the amount applied to purchase such Notes (and such other Senior Indebtedness) pursuant to such offer may be applied by the Issuer for any purpose not prohibited by the Indenture. The Issuer 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 repurchase of the Notes pursuant to this covenant. To the extent that the provisions of any securities laws or regulations conflict with provisions of this covenant, the Issuer will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this covenant by virtue of its compliance with such securities laws or regulations. The Issuer may satisfy its obligations under this covenant with respect to any Net Available Cash by making an Asset Disposition Offer with respect to such Net Available Cash prior to the expiration of the relevant 365 days (or extended period

50

provided above) or with respect to Excess Proceeds of $50 million or less, including by making an offer to purchase Notes pursuant to clause (iii) of the second paragraph of this covenant.

For the purposes of this covenant, the following are deemed to be cash or Temporary Cash Investments:

Limitation on Affiliate Transactions

(a) The Issuer will not, and will not permit any Restricted Subsidiary to, enter into any transaction (including the purchase, sale, lease or exchange of any property, employee compensation arrangements or the rendering of any service) with, or for the benefit of, any Affiliate of the Issuer (an “Affiliate Transaction”) involving aggregate payments or consideration in excess of $35 million unless:

(b) The provisions of the preceding paragraph (a) will not prohibit:

Limitation on Liens

The Issuer will not, and will not permit any Restricted Subsidiary to, directly or indirectly, Incur or permit to exist any Lien (the “Initial Lien”) of any nature whatsoever on any of its properties (including Capital Stock of a Restricted Subsidiary), whether owned at the Issue Date or thereafter acquired, securing any Indebtedness, other than Permitted Liens, without effectively providing that the Notes or the relevant Guarantee of the Notes, as the case may be, shall be secured equally and ratably with (or prior to) the obligations so secured for so long as such obligations are so secured. For the avoidance of doubt, for the purposes of determining whether any Initial Lien is a Permitted Lien following a Suspension Period, any Incurrence of Liens securing Indebtedness shall be tested as though the covenant described under “—Limitation on Indebtedness” was in effect at such time.

Any such Lien thereby created in favor of the Notes or any Subsidiary Guarantee will be automatically and unconditionally released and discharged upon (i) the release and discharge of each Initial Lien to which it relates, (ii) in the case of such Lien in favor of any such Subsidiary Guarantee, upon the termination and discharge of such Subsidiary Guarantee in accordance with the terms of the Indenture or (iii) any sale, exchange or transfer to any Person not an Affiliate of the Issuer of the property or assets secured by such Initial Lien.

The expansion of Liens by virtue of the accrual of interest, the accretion or amortization of original issue discount (excluding accretion or amortization that is expressly provided for in the agreement providing for the applicable Indebtedness that is a zero coupon or other discount instrument) and increases in the amount of Indebtedness outstanding solely as a result of fluctuations in the exchange rate of currencies or increases in the value of the property securing the applicable Indebtedness will not be deemed to be an Incurrence of Liens for purposes of this covenant.

For purposes of determining compliance with this covenant, (A) a Lien securing an item of Indebtedness need not be permitted solely by reference to one category of Permitted Liens (or any portion thereof) described in the definition of “Permitted Liens” or pursuant to the first paragraph of this covenant but may be permitted in part under any combination thereof and (B) in the event that a Lien securing an item of Indebtedness (or any portion thereof) meets the criteria of one or more of the categories of Permitted Liens (or any portion thereof) described in the definition of “Permitted Liens” or pursuant to the first paragraph of this covenant, the Issuer may, in its sole discretion, classify or reclassify, or later divide, classify or reclassify (as if Incurred at such later time), such Lien securing such item of Indebtedness (or any portion thereof) in any manner that complies with this covenant and will be entitled to only include the amount and type of such Lien or such item of Indebtedness secured by such Lien (or any portion thereof) in one of the categories of Permitted Liens (or any portion thereof) described in the definition of “Permitted Liens” or pursuant to the first paragraph of this covenant and, in such event, such Lien securing such item of Indebtedness (or any portion thereof) will be treated as being Incurred or existing pursuant to only such clause or clauses (or any portion thereof) or pursuant to the first paragraph hereof.

Merger and Consolidation

(a) The Issuer will not consolidate with or merge with or into, or convey, transfer or lease, in one transaction or a series of transactions, directly or indirectly, all or substantially all its assets as determined on a consolidated basis to, any Person, unless:

provided, however, that (A) the foregoing will not be applicable to a Restricted Subsidiary consolidating with, merging into or transferring all or part of its properties and assets to the Issuer or one or more Guarantors and (B) clause (3) above will not be applicable to the Issuer merging with an Affiliate of the Issuer solely for the purpose and with the sole effect of reincorporating the Issuer in another jurisdiction.

For purposes of this covenant, the sale, lease, conveyance, assignment, transfer or other disposition of all or substantially all of the properties and assets of one or more Subsidiaries of the Issuer, which properties and assets, if held by the Issuer instead of such Subsidiaries, would constitute all or substantially all of the properties and assets of the Issuer on a consolidated basis, shall be deemed to be the transfer of all or substantially all of the properties and assets of the Issuer, subject to the proviso in the previous sentence.

The Successor Company will be the successor to the Issuer and shall succeed to, and be substituted for, and may exercise every right and power of, the Issuer under the Indenture, and the predecessor Issuer, except in the case of a lease, shall be released from all of its obligations under the Indenture and the Notes.

For all purposes of the Indenture, Subsidiaries of any Successor Company will, upon any transaction subject to this covenant, become Restricted Subsidiaries or Unrestricted Subsidiaries as provided pursuant to the Indenture, and all Indebtedness and Liens of the Successor Company and its Subsidiaries that were not Indebtedness or Liens on property or assets, as the case may be, of the Issuer and its Subsidiaries immediately prior to such transaction shall be deemed to have been Incurred upon such transaction.

(b) The Issuer will not permit any Guarantor to consolidate with or merge with or into, or convey, transfer or lease, in one transaction or a series of transactions, all or substantially all of its assets to any Person unless:

54

Table of Contents

provided, however, that this covenant will not be applicable to a Restricted Subsidiary consolidating with, merging into or transferring all or part of its properties and assets to the Issuer or a Guarantor; provided further that a Guarantor’s Subsidiary Guarantee will be released concurrently with such transactions under “—Subsidiary Guarantees.” Subject to certain limitations described in the Indenture, the successor Person (if other than such Guarantor) will succeed to, and be substituted for, such Guarantor under the Indenture and such Guarantor’s Guarantee.

Notwithstanding the foregoing, any Guarantor may:

Future Subsidiary Guarantors

The Issuer will not cause or permit (a) any of its Wholly-Owned Subsidiaries to Guarantee any Credit Facility Indebtedness or capital markets debt securities of the Issuer or any Guarantor or (b) any of its Restricted Subsidiaries (other than a Foreign Subsidiary or a CFC Holdco) to Incur (other than any Guarantee) Credit Facility Indebtedness or capital markets debt securities (for the avoidance of doubt, other than the Convertible Notes), in each case, unless such Subsidiary is a Guarantor or within 30 days thereof executes and delivers to the Trustee a Guarantee Agreement pursuant to which such Restricted Subsidiary will Guarantee payment of the Notes on the same terms and conditions as those set forth in the Indenture and applicable to the other Guarantors and delivers to the Trustee an Opinion of Counsel (which may contain customary exceptions) that such Guarantee Agreement has been duly authorized, executed and delivered by such Restricted Subsidiary and constitutes a legal, valid, binding and enforceable obligation of such Restricted Subsidiary.

The Issuer may elect, in its sole discretion, to cause any Restricted Subsidiary that is not otherwise required to be a Guarantor to become a Guarantor, in which case such Restricted Subsidiary shall not be required to comply with the 30-day period described in the paragraph above.

SEC Reports

Whether or not required by the rules and regulations of the SEC, so long as any Notes are outstanding, the Issuer will furnish to the Trustee and, upon written request, the Holders, within the time periods specified in the SEC’s rules and regulations for non-accelerated filers:

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 and any Holder, it being understood that the Trustee shall not be responsible for determining whether such filings have been made.

If, notwithstanding the foregoing, the SEC will not accept such filings for any reason, the Issuer will post the reports specified in the preceding sentence on its website within the time periods that would apply if the Issuer were required to file those reports with the SEC as a “non-accelerated filer.”

Notwithstanding anything to the contrary, this covenant does not require the Issuer to comply with Rule 3-10 or Rule 3-16 of Regulation S-X (or any successor provision), or to provide separate financial statements of any Guarantor; provided that the Issuer will continue to provide qualitative information on non-Guarantor Subsidiaries substantially consistent with the information provided in the Offering Memorandum in the reports required to be delivered pursuant to clause (1) above. At any time that any of the Issuer’s Subsidiaries are Unrestricted Subsidiaries and the EBITDA of such Unrestricted Subsidiaries (determined in a manner consistent with the definition of EBITDA in the Indenture) account collectively for more than 1.0% of the Issuer’s corresponding consolidated amount, then the quarterly and annual financial information required by the preceding paragraph will include a reasonably detailed quantitative presentation, either on the face of the financial statements or in the footnotes thereto, and in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” or elsewhere in reports provided by the Issuer pursuant to this covenant of the financial condition and results of operations of the Issuer and its Restricted Subsidiaries separate from the financial condition and results of operations of the Unrestricted Subsidiaries of the Issuer.

In addition, at any time when the Issuer is not subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act, the Issuer will furnish to the Holders and to prospective investors, upon the requests of such Holders, any information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act so long as such Notes held by Persons other than Affiliates of the Issuer are not freely transferable under Rule 144A under the Securities Act.

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 Officers’ Certificates).

Intercompany Transactions

Notwithstanding anything to the contrary, the Intercompany Transactions and any transactions that are related to the Intercompany Transactions, including, but not limited to, the restructuring of certain Subsidiaries of the Issuer and subsequent steps to consolidate duplicative Subsidiaries in various countries, eliminate dormant or unnecessary entities, and rationalize and integrate the supply chains, operations, and workforces, are expressly permitted hereunder.

Defaults

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

However, a default under clause (3) or (4) 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 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 with respect to the Notes, the Trustee by written notice to the Issuer, or the Holders of at least 30% in principal amount of the outstanding Notes by written notice to the Issuer and the Trustee, may declare the principal of and accrued but unpaid interest on all such Notes to be due and payable. Upon such a declaration, such principal and interest shall be due and payable immediately. If an Event of Default under clause (6) with respect to the Issuer, any domestic Significant Subsidiary or Western Digital International Ltd. occurs and is continuing, the principal of and interest on all such 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. 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 involving the Notes.

57

Table of Contents

In case an Event of Default occurs and is continuing with respect to the Indenture, 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 unless such Holders have offered to the Trustee indemnity or security satisfactory to the Trustee against any loss, liability or expense. Except to enforce the right to receive payment of principal, premium (if any) or interest not paid when due, no Holder 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 or that would involve the Trustee in personal liability.

If a Default occurs, is continuing and is actually known to a Trust Officer, the Trustee must send electronically or mail to each Holder 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 or interest on any Notes, the Trustee may withhold notice if and so long as the Trustee determines in good faith that withholding notice is not opposed to the interest of the Holders. 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 of the Notes (including consents obtained in connection with a tender offer or exchange for such 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:

58

Table of Contents

Notwithstanding the preceding, without the consent of any Holder, the Issuer, the Guarantors and Trustee may amend the Indenture:

The consent of the Holders 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.

59

Table of Contents

Satisfaction and Discharge

When (1) we deliver to the Trustee all outstanding Notes (except lost, stolen or destroyed Notes which have been replaced or paid and Notes for whose payment money has theretofore been deposited in trust) for cancellation or (2) all outstanding Notes (i) have become due and payable, whether at maturity or on a redemption date as a result of the mailing of notice of redemption or (ii) will become due and payable within one year or are called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense of, the Issuer, and, in the case of clause (2), we irrevocably deposit with the Trustee funds sufficient to pay at maturity or upon redemption all outstanding Notes, including interest thereon to maturity or such redemption date (and any intervening interest payment between the date of deposit and such maturity or redemption date), and if in either case we pay all other sums payable under the Indenture by us, then the Indenture shall, subject to certain exceptions, cease to be of further effect.

For any redemption referred to above that requires the payment of the Applicable Premium, the amount deposited shall be sufficient for purpose of the Indenture to the extent that an amount is deposited with the Trustee equal to the Applicable Premium calculated as of the date of the notice of redemption, with any deficit on the date of redemption (any such amount, the “Applicable Premium Deficit”) only required to be deposited with the Trustee on or prior to the date of redemption. Any Applicable Premium Deficit shall be set forth in an Officers’ Certificate delivered to the Trustee simultaneously with the deposit of such Applicable Premium Deficit that confirms that such Applicable Premium Deficit shall be applied toward such redemption.

Defeasance

At any time, we may terminate all our obligations under the Notes, the Subsidiary Guarantees and the Indenture (“legal defeasance”), except for certain obligations, including those respecting the defeasance trust (as defined below) and obligations to register the transfer or exchange of the Notes, to replace mutilated, destroyed, lost or stolen Notes and to maintain a registrar and paying agent in respect of the Notes.

In addition, at any time we may terminate our obligations under “—Change of Control” and under the covenants described under “—Certain Covenants” (other than clauses (1) and (4) of the first paragraph of the covenant described under “—Merger and Consolidation”), the operation of the cross acceleration provision, the bankruptcy provisions with respect to Significant Subsidiaries, the judgment default provision and the Subsidiary Guarantee provision described under “—Defaults” above (“covenant defeasance”).

We may exercise our legal defeasance option notwithstanding our prior exercise of our covenant defeasance option. If we exercise our legal defeasance option with respect to the Notes, payment of the Notes may not be accelerated because of an Event of Default with respect thereto. If we exercise our covenant defeasance option with respect to the Notes, payment of the Notes may not be accelerated because of an Event of Default specified in clause (3), (4), (5), (6) (with respect only to Significant Subsidiaries), (7) or (8) under “—Defaults” above or because of the failure of the Issuer to comply with clause (2) or (3) of the first paragraph under “—Certain Covenants—Merger and Consolidation” above. If we exercise our legal defeasance option or our covenant defeasance option with respect to the Notes, each Guarantor will be released from all of its obligations with respect to its Subsidiary Guarantee in respect of the Notes.

In order to exercise either of our defeasance options, we must irrevocably deposit in trust (the “defeasance trust”) with the Trustee money or U.S. Government Obligations for the payment of principal and interest on the Notes to redemption or maturity, as the case may be, and must comply with certain other conditions, including delivery to the Trustee of an Opinion of Counsel to the effect that Holders will not recognize income, gain or loss for Federal income tax purposes as a result of such deposit and defeasance and will be subject to Federal income tax on the same amounts and in the same manner and at the same times as would have been the case if such deposit and defeasance had not occurred (and, in the case of legal defeasance only, such Opinion of Counsel

60

Table of Contents

must be based on a ruling of the Internal Revenue Service or other change in applicable Federal income tax law since the issuance of the Notes). For any redemption referred to above that requires the payment of the Applicable Premium, the second paragraph under “—Satisfaction and Discharge” shall apply.

Notwithstanding the foregoing, an Opinion of Counsel required by the immediately preceding paragraph with respect to legal defeasance need not be delivered if all of the Notes not theretofore delivered to the Trustee for cancellation (x) have become due and payable or (y) will become due and payable within one year or are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Issuer.

Concerning the Trustee

U.S. Bank National Association is to be the Trustee under the Indenture. We have appointed U.S. Bank National Association as registrar and paying agent with regard to the Notes.

The Indenture contains certain limitations on the rights of the Trustee, should it become a creditor of the Issuer, 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; provided, however, if it acquires any conflicting interest it must either eliminate such conflict within 90 days, apply to the SEC for permission to continue or resign.

The Holders of a majority in principal amount of the outstanding Notes will have the right to direct the time, method and place of conducting any proceeding for exercising any remedy available to the Trustee, subject to certain exceptions, with respect to the Notes. If an Event of Default occurs (and is not cured), the Trustee will be required, in the exercise of its power vested under the Indenture, to use the degree of care of a prudent man in the conduct of his own affairs. Subject to such provisions, the Trustee will be under no obligation to exercise any of its rights or powers under the Indenture at the request of any Holder, unless such Holder shall have offered to the Trustee security and indemnity satisfactory to the Trustee against any loss, liability or expense and then only to the extent required by the terms of the Indenture.

No provision of the Indenture will require the Trustee to expend its own funds or otherwise incur financial liability in the performance of its duties thereunder or in the exercise of its rights or powers thereunder if the Trustee has reasonable grounds to believe that repayment of such funds or adequate indemnity against such risk is not reasonably assured to it.

No Personal Liability of Directors, Officers, Employees and Stockholders

No director, officer, employee, incorporator or stockholder of the Issuer or any Guarantor will have any liability for any obligations of the Issuer or any Guarantor under the Notes, any Subsidiary Guarantee, 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. Such waiver and release may not be effective to waive liabilities under the U.S. federal securities laws, and it is the view of the SEC that such a waiver is against public policy.

Governing Law

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

Persons who are not participants may beneficially own securities held by or on behalf of DTC only through participants or indirect participants. DTC has no knowledge of the identity of beneficial owners of securities held by or on behalf of DTC. DTC’s records reflect only the identity of participants to whose accounts securities are credited. The ownership interests and transfer of ownership interests of each beneficial owner of each security held by or on behalf of DTC are recorded on the records of the participants and indirect participants.

DTC has also advised us that, pursuant to procedures established by DTC, ownership of interests in the global notes will be shown on, and the transfer of ownership of such interest will be effected only through, records maintained by DTC (with respect to the participants) or by the participants and the indirect participants (with respect to other owners of beneficial interests in the global notes).

Table of Contents

Investors in the global notes may hold their interests therein directly through DTC if they are participants in such system or indirectly through organizations that are participants or indirect participants in such system. All interests in the global notes will be subject to the procedures and requirements of DTC. The laws of some states require that certain persons take physical delivery of certificates evidencing securities they own. Consequently, the ability to transfer beneficial interests in the global notes to such persons will be limited to that extent. Because DTC can act only on behalf of participants, which in turn act on behalf of indirect participants, the ability of beneficial owners of interests in the global notes to pledge such interests to persons or entities that do not participate in the DTC system, or otherwise take actions in respect of such interests, may be affected by the lack of a physical certificate evidencing such interests.

Except as described below, owners of interests in the global notes will not have New Notes registered in their names, will not receive physical delivery of the New Notes in certificated form and will not be considered the registered owners or holders thereof under the indenture for any purpose.

Payments in respect of the principal of and premium, if any, and interest on the global notes registered in the name of DTC or its nominee will be payable by the Trustee (or the paying agents if other than the Trustee) to DTC in its capacity as the registered holder under the indenture. We and the Trustee will treat the persons in whose names the New Notes, including the global notes, are registered as the owners thereof for the purpose of receiving such payments and for any and all other purposes whatsoever. Consequently, none of us, the Trustee or any agent of ours or the Trustee has or will have any responsibility or liability for:

DTC has advised us that its current practice, upon receipt of any payment in respect of securities such as the New Notes (including principal and interest), is to credit the accounts of the relevant participants with the payment on the payment date in amounts proportionate to their respective holdings in the principal amount of the relevant security as shown on the records of DTC, unless DTC has reason to believe it will not receive payment on such payment date. Payments by the participants and the indirect participants to the beneficial owners of New Notes will be governed by standing instructions and customary practices and will be the responsibility of the participants or the indirect participants and will not be the responsibility of DTC, the Trustee or us. Neither we nor the Trustee will be liable for any delay by DTC or any of its participants in identifying the beneficial owners of the New Notes, and we and the Trustee may conclusively rely on and will be protected in relying on instructions from DTC or its nominee for all purposes.

Interests in the global notes are expected to be eligible to trade in DTC’s Same-Day Funds Settlement System and secondary market trading activity in such interests will therefore settle in immediately available funds, subject in all cases to the rules and procedures of DTC and its participants.

DTC has advised us that it will take any action permitted to be taken by a holder of New Notes only at the direction of one or more participants to whose account with DTC interests in the global notes are credited and only in respect of such portion of the aggregate principal amount of the New Notes as to which such participant or participants has or have given such direction.

Although DTC has agreed to the foregoing procedures to facilitate transfers of interests in the global notes among participants in DTC, it is under no obligation to perform or to continue to perform such procedures, and the procedures may be discontinued at any time. Neither we nor the Trustee will have any responsibility for the performance by DTC or its participants or indirect participants of their respective obligations under the rules and procedures governing their operations.

Exchange of Book-Entry Notes for Certificated Notes

If (i) DTC is at any time unwilling or unable to continue as depositary and a successor depositary is not appointed by us within 90 days, (ii) DTC has ceased to be a clearing agency registered under the Exchange Act and a successor depositary is not appointed by us within 90 days, (iii) we, at our option, notify the Trustee in writing that we elect to cause the issuance of the New Notes in the form of certificated notes, or (iv) an Event of Default has occurred and is continuing, upon request by the holders of the New Notes, we will issue New Notes in certificated form in exchange for global securities. The indenture permits us to determine at any time and in our sole discretion that notes shall no longer be represented by global securities. DTC has advised us that, under its current practices, it would notify its participants of our request, but will only withdraw beneficial interests from the global security at the request of each DTC participant. We would issue definitive certificates in exchange for any beneficial interests withdrawn.

CERTAIN U.S. FEDERAL INCOME TAX CONSIDERATIONS

The following is a summary of certain U.S. federal income tax considerations of the Exchange Offer and the ownership and disposition of the New Notes issued pursuant to the Exchange Offer. 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, or U.S. Holders that have a functional currency other than the U.S. dollar. This summary addresses only holders that purchased the Old Notes upon their original issue from the initial purchaser at the issue price 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. Holders should consult their tax advisors as to the particular tax consequences of participating in the Exchange Offer and holding and disposing of the New Notes. As used in this prospectus, 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.

U.S. Holders

The following is a summary of certain U.S. federal income tax considerations relevant to a beneficial owner of the Notes that is a U.S. Holder participating in the Exchange Offer. 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 considerations (including the potential application of the branch profits tax) applicable to participating in the Exchange Offer and owning and disposing of the Notes.

Participating in the Exchange Offer

Neither the registration of the Exchange Offer pursuant to our obligations under the Registration Rights Agreement nor your receipt of the New Notes in exchange for the Old Notes will constitute a taxable event for U.S. federal income tax purposes. U.S. Holders will retain the tax basis in the New Notes that the U.S. Holder had in the Old Notes, and the U.S. Holder’s holding period for the New Notes will include the U.S. Holder’s holding period for the Old Notes before such Old Notes were registered.

Payments of Stated Interest on the New Notes

Stated interest on a New 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.

Sale, Redemption, Retirement or Other Taxable Disposition of the New Notes

U.S. Holders must recognize taxable gain or loss on the sale, redemption, retirement or other taxable disposition of a New Note. The amount of such gain or loss will generally equal the difference between the amount received for the New Note (less any amounts attributable to accrued but unpaid stated interest, which will be taxable as such) and the adjusted tax basis of the New Note. A U.S. Holder’s adjusted basis in a New Note generally will be the amount the U.S. Holder paid for the Old Note that was exchanged for such New Note. Any

95

Table of Contents

such gain or loss will generally constitute capital gain or loss and will be long-term capital gain or loss if such New Note was held for more than one year (including the U.S. Holder’s holding period for the Old Note). 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

The following is a summary of certain U.S. federal income tax considerations to a beneficial owner of the Notes participating in the Exchange Offer that is not a U.S. Holder (a “Non-U.S. Holder”).

Participating in the Exchange Offer

Neither the registration of the Exchange Offer pursuant to our obligations under the Registration Rights Agreement nor your receipt of the New Notes in exchange for the Old Notes will constitute a taxable event for U.S. federal income tax purposes. Non-U.S. Holders will recognize income in respect of the New Notes at the same time and in the same amounts as the Non-U.S. Holder would have recognized such income in respect of the Old Notes had the Exchange Offer not occurred.

Payments of Stated Interest on the New Notes

If you are a Non-U.S. Holder, you will not be subject to U.S. federal withholding tax on payments of interest on the New 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 the applicable Internal Revenue Service (“IRS”) Form W-8, 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 will generally 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 unless, in the case of gain realized by an individual Non-U.S. Holder, the Non-U.S. Holder is present in the United States for 183 days or more in the taxable year of the disposition and certain other conditions are met, in which case such gain (net of certain U.S. source losses) will be taxed at a rate of 30% unless an applicable income tax treaty provides otherwise.

FATCA

Notwithstanding the foregoing, under the U.S. tax rules known as the Foreign Account Tax Compliance Act (“FATCA”), a Holder will generally be subject to 30% U.S. withholding tax on payments made on (and, after December 31, 2018, gross proceeds from the sale or other taxable disposition of) the Notes if the Holder (i) is, or holds its Notes through, a foreign financial institution that has not entered 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 that has been designated as a “nonparticipating foreign financial institution” if it is subject to an intergovernmental agreement between the United States and a foreign country, or (ii) is, or holds its Notes through, a foreign entity that is not a financial institution and that fails to provide 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. The future adoption of, or implementation of, an intergovernmental agreement between the United States and an applicable foreign country, or future U.S. Treasury regulations, may modify these requirements. You should consult your own tax advisor on how these rules may apply to your investment in the Notes.

96

Table of Contents

Information Reporting and Backup Withholding

Payments of interest on and the proceeds from the sale, redemption, retirement or other taxable disposition of the New Notes generally will be subject to information reporting unless the recipient is a corporation or comes within certain other exempt categories and demonstrates this fact. A U.S. Holder that is not exempt from information reporting may be subject to backup withholding unless such U.S. Holder provides a correct taxpayer identification number, certifies as to no loss of exemption from backup withholding and otherwise complies with applicable requirements of the backup withholding rules. Backup withholding generally will not apply to payments made to a Non-U.S. Holder if the holder provides an applicable IRS Form W-8 or otherwise establishes its non-U.S. status. Copies of information returns reporting payments to a Non-U.S. Holder may be made available to the tax authorities in the country in which the Non-U.S. Holder resides under the provisions of an applicable income tax treaty.

Backup withholding is not an additional tax. The amount of any backup withholding will be allowed as a credit against your U.S. federal income tax liability and may entitle you to a refund, provided that the required information is timely furnished to the IRS.

PLAN OF DISTRIBUTION

Each broker-dealer that receives the New Notes for its own account pursuant to the Exchange Offer must acknowledge that it will deliver a prospectus in connection with any resale of such New Notes. This prospectus, as it may be amended or supplemented from time to time, may be used by a broker-dealer in connection with resales of the New Notes received in exchange for the Old Notes, where such Old Notes were acquired as a result of market-making activities or other trading activities. For a period ending on the earlier of (i) 120 days from the date on which the Exchange Offer Registration Statement is declared effective and (ii) the date on which no broker-dealer is required to deliver a prospectus in connection with market-making or other trading activities, we will make this prospectus, as amended or supplemented, available to any broker-dealer for use in connection with any such resale.

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

We have agreed to pay all expenses incident to the Exchange Offer (including the expenses of one counsel for the holders of the Notes) other than commissions or concessions of any brokers or dealers and will indemnify the holders of the Notes (including any broker-dealers) against certain liabilities, including liabilities under the Securities Act.

USE OF PROCEEDS

We will not receive any proceeds from the issuance of the New Notes in the Exchange Offer. In consideration for issuing the New Notes, we will receive the Old Notes in like principal amount. The Old Notes surrendered in exchange for the New Notes will be retired and cancelled.

Certain legal matters with respect to the validity of the New Notes and the related guarantees will be passed upon for us by Cleary Gottlieb Steen & Hamilton LLP, New York, New York.

This Letter of Transmittal is to be used by holders of the Old Notes. Tender of the Old Notes is to be made using the Automated Tender Offer Program (“ATOP”) of The Depository Trust Company (“DTC”) pursuant to the procedures set forth in the Prospectus under the caption “Description of the Exchange Offer—Procedures for Tendering.” DTC participants that are accepting the Exchange Offer must transmit their acceptance to DTC, which will verify the acceptance and execute a book-entry delivery to the Exchange Agent’s DTC account. DTC will then send a computer-generated message known as an “agent’s message” to the Exchange Agent for its acceptance. For you to validly tender your Old Notes in the Exchange Offer, the Exchange Agent must receive, prior to the Expiration Date, an agent’s message under the ATOP procedures that confirms that:

By using the ATOP procedures to tender the Old Notes, you will not be required to deliver this Letter of Transmittal to the Exchange Agent. However, you will be bound by its terms, and you will be deemed to have made the acknowledgments and the representations and warranties it contains, just as if you had signed it.

The New Notes will be issued in full exchange for the Old Notes in the Exchange Offer, if consummated, on the Settlement Date and will be delivered in book-entry form.

Please read the accompanying instructions carefully.

Ladies and Gentlemen:

Upon the terms and subject to the conditions of the Exchange Offer, the undersigned hereby tenders to the Issuer the aggregate principal amount of Old Notes credited by the undersigned to the Exchange Agent’s account at DTC using ATOP.

The undersigned understands that validly tendered Old Notes (or defectively tendered Old Notes with respect to which the Issuer has waived such defect or caused such defect to be waived) will be deemed to have been accepted by the Issuer if, as and when the Issuer gives oral or written notice thereof to the Exchange Agent. The undersigned understands that, subject to the terms and conditions, the Old Notes properly tendered and accepted (and not validly withdrawn) in accordance with the terms and conditions will be exchanged for the New Notes. The undersigned understands that, under certain circumstances, the Issuer may not be required to accept any of the Old Notes tendered (including any such Old Notes tendered after the Expiration Date). If any Old Notes are not accepted for exchange for any reason (or if the Old Notes are validly withdrawn), such Old Notes will be returned, without expense, to the undersigned’s account at DTC or such other account as designated herein, pursuant to the book-entry transfer procedures described in the Prospectus, as promptly as practicable after the expiration or termination of the Exchange Offer.

By tendering the Old Notes in the Exchange Offer, the undersigned acknowledges that the Exchange Offer is being made based upon the Issuer’s understanding of an interpretation by the staff of the Securities and Exchange Commission (the “SEC”) as set forth in no-action letters issued to other parties, including Exxon Capital Holdings Corporation, SEC No-Action Letter (available May 13, 1988), Morgan Stanley & Co. Incorporated, SEC No-Action Letter (available June 5, 1991) and Shearman & Sterling, SEC No-Action Letter (available July 2, 1993), that the New Notes issued in exchange for the Old Notes pursuant to the Exchange Offer may be offered for resale, resold and otherwise transferred by each holder thereof (other than a broker-dealer who acquires such New Notes directly from the Issuer for resale pursuant to Rule 144A under the Securities Act or any other available exemption under the Securities Act or any such holder that is an “affiliate” of the Issuer within the meaning of Rule 405 under the Securities Act), without compliance with the registration and prospectus delivery provisions of the Securities Act, provided that such New Notes are acquired in the ordinary course of such holder’s business and such holder is not engaged in, and does not intend to engage in, a distribution of such New Notes and has no arrangement with any person to participate in the distribution of such New Notes. If the undersigned is not a broker-dealer, the undersigned represents that it acquires the New Notes in the ordinary course of its business, it is not engaged in, and does not intend to engage in, a distribution of the New Notes and it has no arrangements or understandings with any person to participate in a distribution of the New Notes. If the undersigned is a broker-dealer that will receive the New Notes for its own account in exchange for the Old Notes, it represents that the Old Notes to be exchanged for the New Notes were acquired by it as a result of market-making activities or other trading activities and acknowledges that it will deliver a prospectus in connection with any resale of such New Notes; however, by so acknowledging and by delivering a prospectus, the undersigned will not be deemed to admit that it is an “underwriter” within the meaning of the Securities Act.

Upon agreement to the terms of this Letter of Transmittal pursuant to an agent’s message, the undersigned, or the beneficial holder of the Old Notes on behalf of which the undersigned has tendered, will, subject to that holder’s ability to withdraw its tender, and subject to the terms and conditions of the Exchange Offer generally, hereby:

The representations, warranties and agreements of a holder tendering the Old Notes shall be deemed to be repeated and reconfirmed on and as of the Expiration Date and the Settlement Date. For purposes of this Letter of Transmittal, the “beneficial owner” of any Old Notes means any holder that exercises investment discretion with respect to such Old Notes.

The undersigned understands that tenders may not be withdrawn at any time after the Expiration Date, except as set forth in the Prospectus, unless the Exchange Offer is amended with changes to the terms and conditions that are, in the reasonable judgment of the Issuer, materially adverse to the tendering holders, in which case tenders may be withdrawn under the conditions described in the extension.

If the Exchange Offer is amended in a manner determined by the Issuer to constitute a material change, the Issuer will extend the Exchange Offer for a period of two to ten business days, depending on the significance of the amendment and the manner of disclosure to such holders, if the Exchange Offer would otherwise have expired during such two to ten business day period.

All authority conferred or agreed to be conferred in this Letter of Transmittal and every obligation of the undersigned hereunder shall be binding upon the undersigned’s successors, assigns, heirs, executors, administrators, trustees in bankruptcy and legal representatives of the undersigned and shall not be affected by, and shall survive, the death or incapacity of the undersigned.

Although the Issuer intends to notify holders of defects or irregularities with respect to tenders of the Old Notes, none of the Issuer, the Exchange Agent, the Trustee and any other person will incur any liability for failure to give such notification. Tenders of the Old Notes will not be deemed made until such defects or irregularities have been cured or waived.
