PRELIMINARY PROSPECTUS SUPPLEMENT

(To prospectus dated October 16, 2017)

CDW LLC and CDW Finance Corporation

$630,000,000

        % SENIOR NOTES DUE 2029

Interest payable                  and                 

We are offering $630,000,000 aggregate principal amount of             % senior notes due 2029 (the “notes”). The notes will mature on                 , 2029. Interest will accrue from                  , 2020, and the first interest payment date will be                 , 2021.

We may redeem the notes at any time, in whole or in part, prior to                 , 2023 at a price equal to 100% of the principal amount thereof plus accrued and unpaid interest, if any, to the redemption date and a “make-whole premium.” Thereafter, we may redeem all or part of the notes at the redemption prices set forth herein. In addition, at any time prior to                 , 2023, we may also redeem up to 40% of the aggregate principal amount of the notes with the net cash proceeds from certain equity offerings. If we experience specific kinds of changes of control, we must offer to purchase the notes.

The notes will be unsecured senior obligations of CDW LLC and CDW Finance Corporation (“CDW Finance”), will rank equal in right of payment with all of their existing and future senior indebtedness, but will be effectively subordinated to their existing and future secured indebtedness to the extent of the value of the collateral securing such indebtedness, and will be senior in right of payment to any of their future subordinated indebtedness. The notes will be guaranteed on an unsecured senior basis by CDW Corporation, the direct parent of CDW LLC and CDW Finance, and all of the direct and indirect domestic subsidiaries of CDW LLC that are guarantors under our senior secured term loan facility (the “Term Loan Facility”). The notes will be structurally subordinated to all of the liabilities and preferred stock of each of the subsidiaries of CDW LLC that do not guarantee the notes.

Investing in the notes involves risks. You should refer to “Risk factors” beginning on page S-7 of this prospectus supplement and the periodic reports and other information that we file with the Securities and Exchange Commission (the “SEC”) incorporated by reference in this prospectus supplement and carefully consider that information before deciding to purchase any notes.

Neither the SEC nor any state securities commission has approved or disapproved of these securities or passed upon the accuracy or adequacy of this prospectus supplement or the accompanying prospectus. Any representation to the contrary is a criminal offense.

We expect that delivery of the notes will be made to investors in book-entry form through The Depository Trust Company on or about                 , 2020.

RISK FACTORS

You should carefully consider the following risk factors and the risk factors included under the heading “Risk Factors” in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019, which is incorporated by reference in this prospectus supplement, and evaluate all of the information included and incorporated by reference in this prospectus supplement and the accompanying prospectus, including the filings we make with the SEC, before you decide to purchase any notes. Our business, financial condition, liquidity or results of operations could be materially adversely affected by any of these risks. If any of these risks are realized, the trading price of the notes would likely decline and we may not be able to make payments of interest and principal on the notes, and you may lose all or part of your original investment.

Risks Related to COVID-19

The outbreak of the novel coronavirus (COVID-19) pandemic could adversely impact our business, results of operations, cash flows, financial condition and liquidity.

The global spread of COVID-19 continues to create significant macroeconomic uncertainty, volatility and disruption. Many governments and health authorities have implemented recommendations or mandates intended to stop or slow the further spread of the disease, such as shelter-in-place orders, resulting in the temporary closure of schools and non-essential businesses, or social distancing measures, resulting in modified operations of various businesses including ours, and these measures may remain in place for a significant period of time. While some of these restrictions have been lifted or eased in certain jurisdictions, the resurgence of COVID-19 in other jurisdictions has slowed, and in some cases reversed the reopening process. We could experience disruptions, including as a result of resurgences of COVID-19, that prevent us from meeting the demands of our customers, such as product constraints from our vendor partners and wholesale distributors and other disruptions to our supply chain, disruptions in or restrictions on the ability of our coworkers to work effectively, temporary closures of our distribution facilities and disruptions of commercial delivery services. The impact of COVID-19 and measures implemented to slow the spread have and continue to also cause delay in, or limit the ability of, our customers to make timely payments to us and could increase our costs. In addition, the pandemic has resulted in a widespread health crisis that is adversely affecting the economies and financial markets of many countries, including the US, the UK and Canada. During the COVID-19 pandemic and even after it has subsided, we may experience adverse impacts to our business as a result of the pandemic’s global economic impact, including any recession, economic downturn or volatility, government spending cuts, tightening of credit markets or increased unemployment that has occurred or may occur in the future, which could cause our customers and potential customers to postpone or reduce spending on technology products or services or put downward pressure on prices.

Individually and collectively, the consequences of the COVID-19 pandemic could adversely impact our business, results of operations, cash flows, financial condition and liquidity. Net sales during the second quarter of 2020 decreased as compared to the second quarter of 2019 across all major hardware categories due to the impact of the COVID-19 pandemic on customer demand, in particular with respect to our Corporate and Small Business customers as their purchases tend to reflect confidence in their business prospects, which are driven by their discrete perceptions of business and economic conditions. The extent to which the COVID-19 pandemic impacts our business, results of operations, cash flows, financial condition and liquidity will depend on future developments, which are highly uncertain and cannot be predicted, including, but not limited to, the duration, the severity and further spread of the outbreak, future resurgences and reimplementation of closures, actions taken to contain the virus or treat its impact, and how quickly and to what extent normal economic and operating conditions can resume. To the extent the COVID-19 pandemic adversely affects our business, results of operations, cash flows, financial condition and liquidity, it may also have the effect of heightening many of the other risks described in the “Risk Factors” section of our Annual Report on Form 10-K for the fiscal year ended December 31, 2019, such as those relating to spending on technology products and services by our public sector customers, our level of indebtedness, our need to generate sufficient cash to service our indebtedness, restrictive

S-7

covenants contained in the agreements that govern our indebtedness limiting our ability to incur additional debt, pay dividends or repurchase capital stock, fluctuations in our operating results and volatility of our common stock price.

Risks Related to the Notes

We have a substantial amount of indebtedness, which could have important consequences to our business and prevent us from fulfilling our obligations under the notes.

We have a substantial amount of indebtedness. As of June 30, 2020, after giving effect to this offering, we would have had $3.9 billion of total long-term debt outstanding, as defined by GAAP, and $479.1 million of obligations outstanding under our inventory financing agreements, and the ability to borrow approximately $1.0 billion under our ABL Facility and an additional £50.0 million under our CDW UK revolving credit and term loan facility (the “CDW UK Credit Facility”). Our substantial indebtedness could have important consequences to the holders of the notes, including the following:

We will be required to generate sufficient cash to service our indebtedness, including the notes, and, if not successful, we may be forced to take other actions to satisfy our obligations under our indebtedness.

Our ability to make scheduled payments on or to refinance our debt obligations depends on our financial and operating performance, which is subject to prevailing economic and competitive conditions and to certain financial, business and other factors beyond our control. Our outstanding long-term debt will impose significant cash interest payment obligations on us and, accordingly, we will have to generate significant cash flow from operating activities to fund our debt service obligations. We cannot assure you that we will maintain a level of cash flows from operating activities sufficient to permit us to pay the principal, premium, if any, and interest on our indebtedness.

If our cash flows and capital resources are insufficient to fund our debt service obligations, we may be forced to reduce or delay capital expenditures, sell assets or operations, seek additional debt or equity capital, restructure or refinance our indebtedness, including the notes, or revise or delay our strategic plan. We cannot assure you that we would be able to take any of these actions, that these actions would be successful and permit

S-8

us to meet our scheduled debt service obligations or satisfy our capital requirements, or that these actions would be permitted under the terms of our existing or future debt agreements, including our Senior Credit Facilities, our existing indentures and the indenture that will govern the notes offered hereby. In the absence of such operating results and resources, we could face substantial liquidity problems and might be required to dispose of material assets or operations to meet our debt service and other obligations. Our Senior Credit Facilities restrict our ability to dispose of assets and use the proceeds from the disposition. We may not be able to consummate those dispositions or to obtain the proceeds which we could realize from them and these proceeds may not be adequate to meet any debt service obligations then due.

If we cannot make scheduled payments on our debt, we will be in default and, as a result:

Despite our indebtedness levels, we and our subsidiaries may be able to incur substantially more debt, including secured debt. This could further increase the risks associated with our leverage.

We and our subsidiaries may be able to incur substantial additional indebtedness in the future. The terms of our Senior Credit Facilities and our existing indentures do not, and the indenture that will govern the notes offered hereby will not, fully prohibit us or our subsidiaries from doing so. To the extent that we incur additional indebtedness or such other obligations, the risks associated with our substantial indebtedness described above, including our possible inability to service our debt, will increase. As of June 30, 2020, before and after giving effect to this offering, we would have had approximately $1.0 billion available for additional borrowing under our ABL Facility after taking into account borrowing base limitations (net of $50.0 million of outstanding borrowings and $432.5 million of reserves related to our floorplan sub-facility) and an additional £50 million available under our CDW UK Credit Facility.

Restrictive covenants under our Senior Credit Facilities and, to a lesser degree, our existing indentures may adversely affect our operations and liquidity.

Our Senior Credit Facilities and, to a lesser degree, our existing indentures contain, and any future indebtedness of ours may contain, various covenants that limit our ability to, among other things:

S-9

As a result of these covenants, we are limited in the manner in which we conduct our business and we may be unable to engage in favorable business activities or finance future operations or capital needs. A breach of any of these covenants or any of the other restrictive covenants would result in a default under our Senior Credit Facilities. Upon the occurrence of an event of default under our Senior Credit Facilities, the lenders:

The acceleration of amounts outstanding under our Senior Credit Facilities would trigger an event of default under our existing indentures.

If we were unable to repay those amounts, the lenders under our Senior Credit Facilities could proceed against the collateral granted to them to secure our borrowings thereunder. We have pledged a significant portion of our assets as collateral under our Senior Credit Facilities. If the lenders under our Senior Credit Facilities accelerate the repayment of borrowings, we cannot assure you that we will have sufficient assets to repay our Senior Credit Facilities and our other indebtedness, including the notes, or the ability to borrow sufficient funds to refinance such indebtedness. Even if we were able to obtain new financing, it may not be on commercially reasonable terms, or terms that are acceptable to us.

In addition, under our ABL Facility we are permitted to borrow an aggregate amount of up to $1.5 billion. However, our ability to borrow under our ABL Facility is limited by a borrowing base and a liquidity condition. The borrowing base at any time equals the sum of up to 85% of our and our subsidiary guarantors’ eligible accounts receivable (net of accounts reserves) (up to 30% of such eligible accounts receivable which can consist of federal government accounts receivable) plus the lesser of (i) 75% of our and our subsidiary guarantors’ eligible inventory (valued at cost and net of inventory reserves) and (ii) the product of 85% multiplied by the net orderly liquidation value percentage multiplied by eligible inventory (valued at cost and net of inventory reserves), less reserves (other than accounts reserves and inventory reserves). Our borrowing base in effect as of June 30, 2020 was $2.2 billion, and therefore did not restrict our ability to borrow under the ABL Facility as of that date.

Our ability to borrow under our ABL Facility is also limited by a minimum liquidity condition, which provides that, if excess cash availability is less than the lesser of (i) $125.0 million and (ii) the greater of (A) ten percent (10%) of the borrowing base and (B) $100.0 million, the lenders are not required to lend any additional amounts under the ABL Facility unless the consolidated fixed charge coverage ratio (as defined in the credit agreement evidencing our ABL Facility) is at least 1.00 to 1.00. Moreover, our ABL Facility provides discretion to the agent bank acting on behalf of the lenders to impose additional availability reserves, which could materially impair the amount of borrowings that would otherwise be available to us. We cannot assure you that the agent bank will not impose such reserves or, were it to do so, that the resulting impact of this action would not materially and adversely impair our liquidity.

The notes will be unsecured and will be effectively subordinated to our and the guarantors’ secured debt.

The Issuers’ obligations under the notes and the guarantors’ obligations under the guarantees of the notes will not be secured by any of our or our subsidiaries’ assets. Borrowings under our Senior Credit Facilities are secured by a security interest in substantially all of our assets and the assets of the guarantors. In addition, the indenture that will govern the notes will permit us and our subsidiaries to incur additional secured debt. As a result, the notes and the guarantees will be effectively subordinated to all of the Issuers’ and the guarantors’ secured debt and other obligations to the extent of the value of the assets securing such obligations. As of June 30, 2020, before and after giving effect to this offering, we would have had $1.5 billion of secured debt

S-10

outstanding (excluding $1.6 million of unamortized discount), and approximately $1.0 billion of availability under our ABL Facility after taking into account borrowing base limitations (net of $50.0 million of outstanding borrowings and $432.5 million of reserves related to our floorplan sub-facility). If the Issuers and the guarantors were to become insolvent or otherwise fail to make payments on the notes, holders of the Issuers’ and the guarantors’ secured obligations would be paid first and would receive payments from the assets securing such obligations before the holders of the notes would receive any payments. You may therefore not be fully repaid in the event we become insolvent or otherwise fail to make payments on the notes.

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

Certain of our borrowings, primarily borrowings under our Senior Credit Facilities, are at variable rates of interest and expose us to interest rate risk. As of June 30, 2020, we had $1.5 billion of variable rate debt outstanding. If interest rates increase, our debt service obligations on the variable rate indebtedness would increase even though the amount borrowed remained the same, and our net income would decrease. Although we have entered into interest rate cap agreements on our Term Loan Facility to reduce interest rate volatility, we cannot assure you we will be able to enter into interest rate cap agreements in the future on acceptable terms or that such caps or the caps we have in place now will be effective.

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

Holders of the notes do not have any claim as a creditor against any of our existing subsidiaries that are not guarantors of the notes or against any of our future subsidiaries that do not become guarantors of the notes. Indebtedness and other liabilities, including trade payables of those subsidiaries will be structurally senior to claims of holders of the notes against those subsidiaries. As of June 30, 2020, our non-guarantor subsidiaries had approximately $735.1 million of total liabilities, all of which would have been structurally senior to the notes.

The notes are not guaranteed by our foreign subsidiary and will not be guaranteed by any future foreign subsidiaries. Our non-guarantor subsidiaries are separate and distinct legal entities and have no obligation, contingent or otherwise, to pay any amounts due under the notes, or to make any funds available therefor, whether by dividends, loans, distributions or other payments. In the event of a bankruptcy, liquidation, reorganization or other winding up of any of these non-guarantor subsidiaries or any future subsidiary that is not a guarantor of the notes, these non-guarantor subsidiaries will pay the holders of their debts, holders of preferred equity interests and their trade creditors before they will be able to distribute any of their assets to us (except to the extent we have a claim as a creditor of such non-guarantor subsidiary). Any right that we or the subsidiary guarantors have to receive any assets of any non-guarantor subsidiaries upon the bankruptcy, liquidation, reorganization or other winding up of those subsidiaries, and the consequent rights of holders of notes to realize proceeds from the sale of any of those subsidiaries’ assets, will be effectively subordinated to the claims of those subsidiaries’ creditors, including trade creditors and holders of preferred equity interests of those subsidiaries.

As of and for the six months ended June 30, 2020, our non-guarantor subsidiaries represented approximately 15% of our total assets, 10% of our total liabilities, including trade payables, 12% of our net sales and 8% of our net income, respectively, in each case after intercompany eliminations.

In addition, the indenture that will govern the notes offered hereby, subject to some limitations, permits these subsidiaries to incur additional indebtedness and does not contain any limitation on the amount of certain other liabilities, such as trade payables, that may be incurred by these subsidiaries.

S-11

Our ability to service our debt and meet our cash requirements depends on many factors, some of which are beyond our control.

Our ability to satisfy our obligations and meet our cash requirements for the foreseeable future will depend on our future operating performance and financial results, which will be subject, in part, to factors beyond our control, including interest rates and general economic, financial and business conditions. If we are unable to generate sufficient cash flow to service our debt, we may be required to:

If we are required to take any of these actions, it could have a material adverse effect on our business, financial condition and results of operations. In addition, we cannot assure you that we would be able to take any of these actions, that these actions would enable us to continue to satisfy our capital requirements or that these actions would be permitted under the terms of our various debt instruments, including our Senior Credit Facilities, our existing indentures and the indenture that will govern the notes offered hereby. In addition, our Senior Credit Facilities restrict our ability to sell assets and to use the proceeds from the sales. We may not be able to sell assets quickly enough or for sufficient amounts to enable us to meet our obligations, including our obligations on the notes. Therefore, it may be difficult for us to make required payments on the notes in the event of an acceleration of the maturity of the notes.

Our ability to make payments on the notes depends on our ability to receive dividends and other distributions from our subsidiaries.

Our principal assets are the equity interests that we hold in our operating subsidiaries. As a result, we are dependent on dividends and other distributions from our subsidiaries to generate the funds necessary to meet our financial obligations, including the payment of principal and interest on our outstanding debt. Our subsidiaries may not generate sufficient cash from operations to enable us to make principal and interest payments on our indebtedness, including the notes. In addition, any payment of dividends, distributions, loans or advances to us by our subsidiaries could be subject to restrictions on dividends or, in the case of foreign subsidiaries, restrictions on repatriation of earnings under applicable local law and monetary transfer restrictions in the jurisdictions in which our subsidiaries operate. In addition, payments to us by our subsidiaries will be contingent upon our subsidiaries’ earnings. Our subsidiaries are permitted under the terms of our indebtedness to incur additional indebtedness that may restrict payments from those subsidiaries to us. We cannot assure you that agreements governing current and future indebtedness of our subsidiaries will permit those subsidiaries to provide us with sufficient cash to fund payments on the notes when due.

Our subsidiaries are legally distinct from us and, except for our existing and future subsidiaries that will be guarantors of the notes, have no obligation, contingent or otherwise, to pay amounts due on our debt or to make funds available to us for such payment.

If we default on our obligations to pay our indebtedness, we may not be able to make payments on the notes.

Any default under the agreements governing our indebtedness, including a default under our Senior Credit Facilities that is not waived by the required lenders, and the remedies sought by the holders of such indebtedness, could make us unable to pay principal, premium, if any, and interest on the notes and substantially decrease the value of the notes. If we are unable to generate sufficient cash flow and are otherwise unable to obtain funds

S-12

necessary to meet required payments of principal, premium, if any, and interest on our indebtedness, or if we otherwise fail to comply with the various covenants, including financial and operating covenants, in the instruments governing our indebtedness (including covenants in our Senior Credit Facilities and, to a lesser degree, the indentures governing our 2024 Senior Notes, our 4.125% 2025 Senior Notes, our 2028 Senior Notes and the indenture that will govern the notes offered hereby), we could be in default under the terms of the agreements governing such indebtedness, including our Senior Credit Facilities, our existing indentures and the indenture that will govern the notes offered hereby. In the event of such default, the holders of such indebtedness could elect to declare all the funds borrowed thereunder to be due and payable, together with accrued and unpaid interest, the lenders under our Senior Credit Facilities could elect to terminate their commitments thereunder and cease making further loans and lenders under our Senior Credit Facilities could institute foreclosure proceedings against our assets and we could be forced into bankruptcy or liquidation. If our operating performance declines, we may in the future need to obtain waivers from the required lenders under our Senior Credit Facilities to avoid being in default. If we breach our covenants under our Senior Credit Facilities and seek a waiver, we may not be able to obtain a waiver from the required lenders. If this occurs, we would be in default under our Senior Credit Facilities, the lenders could exercise their rights, as described above, and we could be forced into bankruptcy or liquidation. See “Description of Notes” in this prospectus supplement.

We may be unable to purchase the notes upon a change of control which would result in a default under the indenture that will govern the notes offered hereby and would adversely affect our business.

Upon a change of control, as defined in the indenture that will govern the notes, we are required to offer to purchase all of the notes then outstanding for cash at 101% of the principal amount thereof, together with accrued and unpaid interest and additional interest, if any. If a change of control occurs under the indenture that will govern the notes, we may not have sufficient funds to pay the change of control purchase price, and we may be required to secure third party financing to do so. We may not be able to obtain this financing on commercially reasonable terms, or on terms acceptable to us, or at all. We are subject to similar repurchase obligations under the indentures governing our other outstanding notes, which may additionally increase our risk of not having sufficient funds to pay for all tendered notes. Further, we may be contractually restricted under the terms of our Senior Credit Facilities from repurchasing all of the notes tendered by holders of the notes upon a change of control. Accordingly, we may not be able to satisfy our obligations to purchase the notes unless we are able to refinance or obtain waivers under our Senior Credit Facilities. Our failure to repurchase the notes upon a change of control would cause a default under the indenture that will govern the notes offered hereby and a cross-default under the Senior Credit Facilities and our other indentures. Our Senior Credit Facilities also provide that a change of control, as defined in such agreement, will be a default that permits lenders to accelerate the maturity of borrowings thereunder and, if such debt is not paid, to enforce security interests in the collateral securing such debt, thereby limiting our ability to raise cash to purchase the notes.

The change of control provisions in the indenture that will govern the notes offered hereby may not protect holders of the notes in the event we consummate a highly leveraged transaction, reorganization, restructuring, merger or other similar transaction, unless such transaction constitutes a change of control under the indenture that will govern the notes offered hereby. Such a transaction may not involve a change in voting power or beneficial ownership or, even if it does, may not involve a change in the magnitude required under the definition of change of control in the indenture that will govern the notes offered hereby to trigger our obligation to repurchase the notes. Except as otherwise described above, the indenture that will govern the notes offered hereby does not contain provisions that permit the holders of the notes to require us to repurchase or redeem the notes in the event of a takeover, recapitalization or similar transaction. If an event occurs that does not constitute a “Change of Control” as defined in the indenture that will govern the notes offered hereby, we will not be required to make an offer to repurchase the notes and holders may be required to continue to hold notes despite the event.

See “Description of Notes—Repurchase at the Option of Holders” in this prospectus supplement.

S-13

Federal and state statutes allow courts, under specific circumstances, to void notes and adversely affect the validity and enforceability of the guarantees and require noteholders to return payments received.

The issuance of, and payments made under, the notes and the guarantees may be subject to review under federal and state fraudulent transfer and conveyance statutes. While the relevant laws may vary from state to state, generally under such laws the incurrence of an obligation (such as under the notes or guarantees) or the making of a payment or other transfer will be a fraudulent conveyance if (1) we or any of our guarantors, as applicable, incurred such obligation or made such payment with the intent of hindering, delaying or defrauding creditors or (2) we or any of our guarantors, as applicable, received less than reasonably equivalent value or fair consideration in return for incurring such obligation or making such payment and, in the case of (2) only, one of the following is also true:

If a court were to find that the issuance of the notes or guarantees, or a payment made under the notes or guarantees, was a fraudulent conveyance, the court could void the payment obligations under the notes or such guarantees or subordinate the notes or such guarantees to presently existing and future indebtedness of ours or any such guarantor, and require the holders of the notes to repay particular amounts or any amounts received with respect to the notes or such guarantees. In the event of a finding that a fraudulent conveyance occurred, you may not receive any repayment on the notes. Further, the voiding of the notes or the guarantees could result in an event of default with respect to our other debt and that of our guarantors that could result in acceleration of such debt.

The measures of insolvency for purposes of these fraudulent transfer laws will vary depending upon the law applied in any proceeding to determine whether a fraudulent transfer has occurred. In general, however, a court would consider an issuer or a guarantor insolvent if:

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 notes and the guarantees would not be subordinated to our or any guarantor’s other 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 reasonably equivalent value or fair consideration. A court could thus void the obligations under the guarantees, subordinate them to the applicable guarantor’s other debt or take other action detrimental to the holders of the notes.

Each guarantee contains a provision intended to limit the guarantor’s liability to the maximum amount that it could incur without causing the incurrence of obligations under its guarantee to be a fraudulent transfer. This provision may not be effective to protect the guarantees from being voided under fraudulent transfer law, or may

S-14

reduce or eliminate the guarantor’s obligation to an amount that effectively makes the guarantee worthless. Although subsequently overturned on other grounds, a recent Florida bankruptcy court decision found that this kind of provision was ineffective to protect the guarantees.

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 or discontinue rating companies, including us. Any ratings downgrade or decisions by a credit rating agency to discontinue rating us could adversely affect the trading price of the notes, or the trading market for the notes, to the extent a trading market for the notes develops. The condition of the financial and credit markets and prevailing interest rates have fluctuated in the past and are likely to fluctuate in the future and any fluctuation may impact the trading price of the notes.

We cannot assure you that an active trading market will develop for the notes.

Prior to this offering, there has been no trading market for the notes, and we do not intend to apply to list the notes on any securities exchange or to arrange for quotation on any automated dealer quotation system. We have been informed by the underwriters that they intend to make a market in the notes after this offering is completed. However, the underwriters may cease their market-making at any time without notice. In addition, the liquidity of the trading market in the notes, and the market price quoted for the notes, may be adversely affected by changes in the overall market for this type of security and by changes in our financial performance or prospects or in the prospects for companies in our industry generally. As a result, we cannot assure you that an active trading market will develop for the notes. If an active trading market does not develop or is not maintained, the market price and liquidity of the notes may be adversely affected. In that case you may not be able to sell your notes at a particular time or you may not be able to sell your notes at a favorable price.

We will use the proceeds from the sale of the notes, together with cash on hand, (a) to fund the redemption of $600.0 million aggregate principal amount of our outstanding 2025 Senior Notes, representing all of the 2025 Senior Notes currently outstanding, at a redemption price of 103.750% of the principal amount redeemed plus accrued and unpaid interest to the date of redemption, and (b) to pay fees and expenses related to the redemption and this offering. Certain of the underwriters and/or their respective affiliates own a portion of the 2025 Senior Notes for their own account and will therefore receive a portion of the net proceeds from this offering used to redeem the 2025 Senior Notes.

Our 2025 Senior Notes bear interest at 5.0% per annum and mature on September 1, 2025.

DESCRIPTION OF NOTES

CDW LLC (“CDW”) and CDW Finance Corporation (“FinanceCo,” and together with CDW, the “Issuers”) will issue $630 million of             % senior notes due 2029 (the “Notes”) under the indenture dated on December 1, 2014 (the “Base Indenture”) among CDW LLC, CDW Finance Corporation, the Guarantors and U.S. Bank National Association, as trustee (the “Trustee”), as supplemented by the supplemental indenture to be dated on or about August         , 2020 (the “Supplemental Indenture,” and together with the Base Indenture, the “Indenture”) among CDW LLC, CDW Finance Corporation, the Guarantors and the Trustee. The terms of the Notes include those stated in the Indenture and those expressly made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”).

In this description, the term “Issuers” refers only to CDW LLC and CDW Finance Corporation and not to any of their Subsidiaries, the term “CDW” refers only to CDW LLC and not to any of its Subsidiaries. CDW Finance Corporation was formed on August 6, 2010 for the sole purpose of acting as a co-Issuer of debt securities and does not have any material assets. For a description of restrictions on CDW Finance Corporation’s activities, see “—Certain Covenants—Restrictions on Activities of CDW Finance Corporation.”

The following description is a summary of the material provisions of the Indenture, the Notes and the Guarantees. The following description does not restate these documents in their entirety. You are encouraged to read these documents because they, and not this description, define your rights as Holders of the Notes.

Certain defined terms used in this description but not defined below under “—Certain Definitions” have the meanings assigned to them in the Indenture.

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

Brief Description of the Notes and the Guarantees

The Notes and the Guarantees thereof:

S-18

Substantially all of the operations of CDW are conducted through its Subsidiaries, but not all of CDW’s Subsidiaries will Guarantee the Notes. Unless a Subsidiary is a Guarantor, claims of creditors of such Subsidiary, including trade creditors, and claims of preferred stockholders (if any) of such Subsidiary generally will have priority with respect to the assets and earnings of such Subsidiary over the claims of creditors of CDW, including Holders of the Notes. The Notes, therefore, will be structurally subordinated to creditors (including trade creditors) and preferred stockholders (if any) of Subsidiaries of CDW that are not Guarantors. For the six months ended June 30, 2020, the non-guarantor Subsidiaries generated approximately 12% and 8% of CDW’s net sales and net income, respectively. In addition, as of June 30, 2020, the non-guarantor Subsidiaries held approximately 15% of CDW’s consolidated total assets and had approximately $735.1 million of total liabilities, all of which would have been structurally senior to the Notes. See “Risk Factors—Risks Related to the Notes—The notes are structurally subordinated to all indebtedness of our existing or future subsidiaries that do not become guarantors of the notes.”

The Indebtedness evidenced by the Notes is unsecured Senior Indebtedness of the Issuers and the Guarantors, and as such, will be effectively subordinated to any Secured Indebtedness or other secured obligations of the Issuers and the Guarantors to the extent of the value of the assets securing such Secured Indebtedness. As of June 30, 2020, before and after giving effect to this offering, CDW and its Subsidiaries would have had $1.5 billion of Secured Indebtedness outstanding (excluding $1.6 million of unamortized discount), and approximately $1.0 billion of availability under our ABL Facility after taking into account borrowing base limitations (net of $50.0 million of outstanding borrowings and $432.5 million of reserves related to our floorplan sub-facility). See “Risk Factors—Risks Related to the Notes—The notes will be unsecured and will be effectively subordinated to our and our guarantors’ secured debt.”

Principal, Maturity and Interest

The Issuers will issue $630 million in aggregate principal amount of Notes in this offering. The Issuers may issue additional Notes under the Indenture from time to time after this offering. The Notes and any additional Notes contemporaneously or subsequently issued under the Indenture will be treated as a single class for all purposes under the Indenture, including, without limitation, waivers, amendments, redemptions and offers to purchase. It is possible, however, that the Notes and any other additional Notes will not be treated as part of the same issue for U.S. federal income tax purposes. The Issuers will issue the Notes in denominations of $2,000 and integral multiples of $1,000 in excess of $2,000. The Notes will mature on                     , 2029.

Interest on the Notes will accrue at the rate of             % per annum and will be payable semi-annually in arrears on              and             , commencing on             , 2021. The Issuers will make each interest payment to the Holders of record on the immediately preceding             and             .

Interest is computed on the basis of a 360-day year comprised of twelve 30-day months. Interest accrues from the date it was most recently paid.

Paying Agent and Registrar for the Notes

CDW will maintain one or more paying agents (each, a “paying agent”) for the Notes within the City and State of New York.

CDW will also maintain one or more registrars (each, a “registrar”) and a transfer agent. The Trustee will serve as initial registrar and transfer agent at its corporate trust office. The registrar and the transfer agent will maintain a register reflecting ownership of Notes outstanding from time to time and will make payments on and facilitate transfer of Notes on behalf of CDW at the office or agency of the registrar within the City and State of New York.

CDW may change the paying agents, the registrars or the transfer agents without prior notice to the Holders. CDW or any Restricted Subsidiary may act as a paying agent or registrar.

S-19

Transfer and Exchange

A Holder may transfer or exchange Notes in accordance with the Indenture. The registrar and the Trustee may require a Holder to furnish appropriate endorsements and transfer documents in connection with a transfer of Notes. Holders will be required to pay all taxes due on transfer. CDW is not required to transfer or exchange any Note selected for redemption. Also, CDW is not required to transfer or exchange any Note for a period of 15 days before a selection of Notes to be redeemed.

Guarantees

The Guarantors will jointly and severally fully and unconditionally guarantee, on a senior unsecured basis, the performance and full and punctual payment when due, whether at maturity, by acceleration or otherwise, of all obligations of the Issuers under the Notes, whether for payment of principal of, premium, if any, or interest in respect of the Notes, expenses, indemnification or otherwise, on the terms set forth in the Indenture.

Parent and the Restricted Subsidiaries which guarantee the Senior Secured Term Loan will initially guarantee the Notes. Each of the Guarantees of the Notes will be a general unsecured senior obligation of each Guarantor.

The obligations of each Guarantor (other than a company that is a direct or indirect parent of CDW) under its Guarantee will be limited as necessary to prevent the Guarantee from constituting a fraudulent conveyance under applicable law.

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

If a Guarantee were rendered voidable, it could be subordinated by a court to all other indebtedness (including guarantees and other contingent liabilities) of the Guarantor, and, depending on the amount of such indebtedness, a Guarantor’s liability on its Guarantee could be reduced to zero. See “Risk Factors—Risks Related to the Notes—Federal and state statutes allow courts, under specific circumstances, to void notes and adversely affect the validity and enforceability of the guarantees and require noteholders to return payments received.”

Each Guarantor may consolidate with or merge into or sell its assets to CDW or another Guarantor without limitation, or with, into or to any other Persons upon the terms and conditions set forth in the Indenture. See “—Certain Covenants—Merger, Consolidation or Sale of Assets.” The Guarantee of a Guarantor will be automatically released and discharged in the event that:

S-20

Optional Redemption

At any time prior to                     , 2023, the Issuers may on any one or more occasions redeem up to 40% of the aggregate principal amount of Notes issued under the Indenture at a redemption price of             % of the principal amount, plus accrued and unpaid interest, if any, to the redemption date, with the net cash proceeds of one or more Equity Offerings; provided that:

At any time prior to                     , 2023, the Issuers may redeem all or a part of the Notes, upon not less than 30 nor more than 60 days’ prior notice mailed by first-class mail, or delivered electronically if held by DTC, to each Holder’s registered address, at a redemption price equal to 100% of the principal amount of Notes redeemed plus the Applicable Premium as of the date of redemption, and accrued and unpaid interest, if any, to the date of redemption, subject to the rights of Holders of Notes on any relevant record date to receive interest due on the relevant interest payment date.

Except pursuant to the preceding paragraph, the Notes will not be redeemable prior to                     , 2023.

On or after                     , 2023, the Issuers may redeem all or part of the Notes upon not less than 30 nor more than 60 days’ notice mailed by first-class mail, or delivered electronically if held by DTC, to each Holder’s registered address, at the redemption prices (expressed as percentages of principal amount) set forth below plus accrued and unpaid interest, if any, to the date of redemption, subject to the rights of Holders of Notes on any relevant record date to receive interest due on the relevant interest payment date, if redeemed during the twelve-month period beginning on                  of the years indicated below.

In addition, the Issuers may acquire Notes by means other than a redemption, whether by tender offer, open market purchases, negotiated transactions or otherwise, in accordance with applicable securities laws, so long as such acquisition does not otherwise violate the terms of the Indenture.

S-21

Notice of any redemption of the Notes in connection with a corporate transaction (including an Equity Offering, an incurrence of Indebtedness or a Change of Control) may, at the Issuers’ discretion, be given prior to the completion thereof and any such redemption or notice may, at the Issuers’ discretion, be subject to one or more conditions precedent, including, but not limited to, completion of the related transaction. If such redemption or purchase is so subject to satisfaction of one or more conditions precedent, such notice shall describe each such condition, and if applicable, shall state that, in the Issuers’ discretion, the redemption date may be delayed until such time as any or all such conditions shall be satisfied, or such redemption or purchase may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied by the redemption date, or by the redemption date as so delayed. In addition, the Issuers may provide in such notice that payment of the redemption price and performance of the Issuers’ obligations with respect to such redemption may be performed by another Person.

Notwithstanding the foregoing, in connection with any tender offer for the Notes, including a Change of Control Offer, if Holders of not less than 90% in aggregate principal amount of the outstanding Notes validly tender and do not withdraw such Notes in such tender offer and the Issuers, or any third party making such a tender offer in lieu of the Issuers, purchase all of the Notes validly tendered and not withdrawn by such Holders, the Issuers or such third party will have the right upon not less than 10 nor more than 60 days’ prior notice, given not more than 30 days following such purchase date, to redeem all Notes that remain outstanding following such purchase at a redemption price equal to the price offered to each other Holder (excluding any early tender or incentive fee) in such tender offer plus, to the extent not included in the tender offer payment, accrued and unpaid interest, if any, thereon, to, but excluding, the date of such redemption.

Mandatory Redemption

The Issuers are not required to make mandatory redemption or sinking fund payments with respect to the Notes. However, under certain circumstances, the Issuers may be required to offer to purchase Notes as described under “—Repurchase at the Option of Holders—Change of Control.” The Issuers may at any time and from time to time purchase Notes in the open market or otherwise as permitted by the Indenture.

Repurchase at the Option of Holders

Change of Control

If a Change of Control occurs, unless CDW at such time has given notice of redemption under “—Optional Redemption” with respect to all outstanding Notes, each Holder of Notes will have the right to require CDW to repurchase all or any part (equal to $2,000 or integral multiples of $1,000 in excess thereof) of that Holder’s Notes pursuant to an offer on the terms set forth in the Indenture (a “Change of Control Offer”). In the Change of Control Offer, CDW will offer a payment (a “Change of Control Payment”) in cash equal to 101% of the aggregate principal amount of the Notes repurchased plus accrued and unpaid interest, if any, on the Notes repurchased, to the date of purchase. Within 30 days following any Change of Control, unless CDW at such time has given notice of redemption under “—Optional Redemption” with respect to all outstanding Notes, or, at CDW’s option and as set forth below, in advance of a Change of Control, CDW will mail or electronically deliver a notice to each Holder, with a copy to the Trustee, describing the transaction or transactions that constitute the Change of Control and offering to repurchase Notes on the date of such Change of Control Payment specified in the notice, which date will be no earlier than 30 days and no later than 60 days from the date such notice is mailed or electronically delivered (the “Change of Control Payment Date”), pursuant to the procedures required by the Indenture and described in such notice. CDW will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control provisions of the Indenture, CDW will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the Change of Control provisions of the Indenture by virtue of such conflict.

S-22

On the Change of Control Payment Date, CDW will, to the extent lawful:

The paying agent will promptly mail or deliver by electronic means (in the case of global notes) to each Holder of Notes properly tendered the Change of Control Payment for such Notes, and the Trustee will promptly authenticate and mail (or cause to be transferred by book entry) to each Holder a new Note equal in principal amount to any unpurchased portion of the Notes surrendered, if any; provided that each new Note will be in a minimum principal amount of $2,000 or integral multiples of $1,000 in excess thereof. CDW will publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date.

CDW will not be required to make a Change of Control Offer upon a Change of Control if (i) 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 CDW and purchases all Notes properly tendered and not withdrawn under the Change of Control Offer or (ii) a notice of redemption has been given pursuant to the Indenture as described under “—Optional Redemption” unless and until there is a default in the payment of the applicable redemption price. A Change of Control Offer may be made in advance of a Change of Control and may be conditional upon the occurrence of a Change of Control, if a definitive agreement is in place for the Change of Control at the time the Change of Control Offer is made.

Each of the ABL Facility and the Senior Secured Term Loan contains certain prohibitions on CDW and its Subsidiaries purchasing Notes, and also provides that the occurrence of certain change of control events with respect to Parent or CDW would constitute a default thereunder. Prior to complying with any of the provisions of this “Change of Control” covenant under the Indenture governing the Notes, but in any event within 90 days following a Change of Control, to the extent required to permit CDW to comply with this covenant, CDW will need to either repay all outstanding Indebtedness under the ABL Facility and the Senior Secured Term Loan or other Indebtedness ranking pari passu with the Notes or obtain the requisite consents, if any, under all agreements governing such outstanding Indebtedness. If CDW does not repay such Indebtedness or obtain such consents, CDW will remain prohibited from purchasing Notes in a Change of Control, which after appropriate notice and lapse of time would result in an Event of Default under the Indenture, which would in turn constitute a default under the ABL Facility and the Senior Secured Term Loan.

Future Indebtedness that CDW or its Subsidiaries may incur may contain prohibitions on the occurrence of certain events that would constitute a Change of Control or require the repurchase of such indebtedness upon a Change of Control. Moreover, the exercise by the Holders of their right to require CDW to repurchase their Notes could cause a default under such Indebtedness, even if the Change of Control itself does not, due to the financial effect of such repurchase on CDW or its Subsidiaries. Finally, CDW’s ability to pay cash to the Holders of Notes following the occurrence of a Change of Control may be limited by its then existing financial resources. There can be no assurance that sufficient funds will be available when necessary to make any required repurchases. See “Risk Factors—Risks Related to the Notes—We may be unable to purchase the notes upon a change of control which would result in a default under the indenture that will govern the notes offered hereby and would adversely affect our business.”

The provisions described above that require CDW to make a Change of Control Offer following a Change of Control will be applicable whether or not any other provisions of the Indenture are applicable. Except as

S-23

described above with respect to a Change of Control, the Indenture does not contain provisions that permit the Holders of the Notes to require that CDW repurchase or redeem the Notes in the event of a takeover, recapitalization or similar transaction.

The Change of Control purchase feature of the Notes may in certain circumstances make more difficult or discourage a sale or takeover of CDW or its Subsidiaries and, thus, the removal of incumbent management. CDW has no present intention to engage in a transaction involving a Change of Control, although it is possible that CDW could decide to do so in the future. Subject to the limitations discussed below, CDW or its Subsidiaries 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 the capital structure of CDW or its credit ratings. The Indenture does not contain any covenants or provisions that may afford Holders of the Notes protection in the event of a highly leveraged transaction.

The definition of “Change of Control” includes a phrase relating to the direct or indirect sale, lease, transfer, conveyance or other disposition of “all or substantially all” of the properties or assets of CDW and its Subsidiaries taken as a whole. Although there is a limited body of case law interpreting the phrase “substantially all,” there is no precise established definition of the phrase under applicable law. Accordingly, the ability of a Holder of Notes to require CDW to repurchase its Notes as a result of a sale, lease, transfer, conveyance or other disposition of less than all of the assets of CDW and its Subsidiaries taken as a whole to another Person or group may be uncertain. In addition, the Chancery Court of Delaware has raised the possibility that a “Change of Control” as a result of a failure to have “continuing directors” comprising a majority of a Board of Directors may be unenforceable on public policy grounds.

Selection and Notice

If less than all of the Notes are to be redeemed at any time, the Trustee will select Notes for redemption on a pro rata basis to the extent practicable or by lot, in any case subject to the procedures of The Depository Trust Company.

No Notes of $2,000 or less can be redeemed in part. Except as otherwise provided herein, in the case of global notes, notices of redemption will be delivered electronically at least 30 but not more than 60 days before the redemption date to each Holder of Notes, except that redemption notices may be delivered more than 60 days prior to a redemption date if the notice is issued in connection with a defeasance of the Notes or a satisfaction and discharge 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 of that Note that is to be redeemed. A new Note in principal amount equal to the unredeemed portion of the original Note will be issued in the name of the Holder of that Note upon cancellation of the original Note. Subject to the terms of the applicable redemption notice (including any conditions contained therein), Notes called for redemption become due on the date fixed for redemption. On and after the redemption date, interest ceases to accrue on Notes or portions of them called for redemption.

Certain Covenants

Set forth below are summaries of certain covenants that are contained in the Indenture, which bind CDW and its Restricted Subsidiaries.

Incurrence of Non-guarantor Indebtedness and Issuance of Non-guarantor Preferred Stock

CDW shall not permit any of its Restricted Subsidiaries that are not Guarantors to, directly or indirectly, create, incur, issue, assume, guarantee or otherwise become directly or indirectly liable, contingently or

S-24

otherwise, with respect to (collectively “incur”) any Non-Guarantor Indebtedness (including Acquired Debt) and shall not permit any of its Restricted Subsidiaries that are not Guarantors to issue any shares of Preferred Stock (“Non-Guarantor Preferred Stock”); provided, however, that any Restricted Subsidiary that is not a Guarantor may incur Non-Guarantor Indebtedness (including Acquired Debt) and issue Non-Guarantor Preferred Stock if after giving pro forma effect thereto (including the application of proceeds therefrom), either (x) the Consolidated Non-Guarantor Debt Ratio would be no greater than 3.00 to 1.00 or (y) the aggregate principal amount of Non-Guarantor Indebtedness and Non-Guarantor Preferred Stock would be no greater than $2,000.0 million.

The foregoing restriction shall not apply to the following items:

S-25

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 of the Indebtedness being 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 will be determined on the date such refinancing Indebtedness is incurred. The maximum amount of Indebtedness that the Restricted Subsidiaries may incur pursuant to this covenant shall not

S-26

be deemed to be exceeded, with respect to any outstanding Indebtedness, solely as a result of fluctuations in the exchange rate of currencies.

Liens

CDW will not, and will not permit any of the Restricted Subsidiaries to, directly or indirectly, create, incur, assume or suffer to exist any Lien (except Permitted Liens) on any Principal Property of CDW or such Restricted Subsidiary securing Indebtedness unless the Notes are equally and ratably secured with (or on a senior basis to, in the case of obligations subordinated in right of payment to the Notes) the obligations so secured until such time as such obligations are no longer secured by a Lien. The preceding sentence will not require CDW or any Restricted Subsidiary to secure the Notes if the Lien consists of a Permitted Lien. Any Lien created for the benefit of the Holders of the Notes pursuant to the preceding paragraph shall provide by its terms that such Lien shall be automatically and unconditionally released and discharged upon the release and discharge of the initial Lien that gave rise to the obligation to so secure the Notes.

Sale and Lease-back Transactions

CDW will not and will not permit any Restricted Subsidiary to, enter into any Sale and Lease-Back Transaction with respect to any Principal Property with another Person (other than with CDW or Restricted Subsidiaries) unless either:

Merger, Consolidation or Sale of Assets

CDW may not, directly or indirectly: (1) consolidate or merge with or into another Person (whether or not CDW is the surviving corporation); or (2) sell, assign, transfer, convey, lease or otherwise dispose of all or substantially all of the properties or assets of CDW and its Restricted Subsidiaries, taken as a whole, in one or more related transactions, to another Person; unless:

Notwithstanding the foregoing, (i) clauses (3) and (4) above will not be applicable to: (a) any Restricted Subsidiary consolidating with, merging into or selling, assigning, transferring, conveying, leasing or otherwise

S-27

disposing of all or part of its properties and assets to CDW or to another Guarantor; and (b) CDW merging with an Affiliate solely for the purpose of reincorporating CDW, as the case may be, in another jurisdiction; and (ii) any Foreign Subsidiary may consolidate with or merge into or transfer all or part of its properties and assets to any other Foreign Subsidiary; provided that if the Foreign Subsidiary so consolidating, merging or transferring all or part of its properties and assets is a Foreign Subsidiary that is a Guarantor, such Foreign Subsidiary shall, substantially simultaneously with such merger, transfer or disposition, terminate its Guarantee and otherwise be in compliance with the terms of the Indenture.

The predecessor company will be released from its obligations under the Indenture and the Notes and the Successor Company will succeed to, and be substituted for, and may exercise every right and power of, CDW under the Indenture and the Notes, but, in the case of a lease of all or substantially all its assets, the predecessor company will not be released from the obligation to pay the principal of and interest on the Notes.

Subject to certain limitations described in the Indenture governing release of a Guarantee upon the sale, disposition or transfer of a Guarantor, each Guarantor (other than Parent) will not, and CDW will not permit such Guarantor to, (1) consolidate or merge with or into another Person (whether or not such Guarantor is the surviving Person); or (2) sell, assign, transfer, convey, lease or otherwise dispose of all or substantially all of its properties or assets; unless:

In case of any such consolidation, merger, sale or conveyance and upon the assumption by the successor Person, by supplemental indenture, executed and delivered, together with an Opinion of Counsel and an Officers’ Certificate to the effect that such consolidation, merger, sale or conveyance was made in accordance with the provisions of the Indenture and all conditions precedent thereto have been complied with, to the Trustee and satisfactory in form to the Trustee, of the Guarantee and the due and punctual performance of all of the covenants and conditions of the Indenture to be performed by the Guarantor, such successor Person shall succeed to and be substituted for the Guarantor with the same effect as if it had been named herein as a Guarantor. All the Guarantees so issued shall in all respects have the same legal rank and benefit under this Indenture as the Guarantees theretofore and thereafter issued in accordance with the terms of this Indenture as though all such Guarantees had been issued at the date of the execution hereof.

Notwithstanding the foregoing, any Guarantor may (A) consolidate with, merge into or sell, assign, transfer, convey, lease or otherwise dispose of all or part of its properties and assets to CDW or to another Guarantor or (B) dissolve, liquidate or windup its affairs if at that time it does not hold any material assets.

The Indenture provides that Parent will not (1) consolidate or merge with or into another Person (whether or not Parent is the surviving corporation); or (2) sell, assign, transfer, convey, lease or otherwise dispose of all or substantially all of its properties or assets; unless:

S-28

In case of any such consolidation, merger, sale or conveyance and upon the assumption by the successor Person, by supplemental indenture, executed and delivered, together with an Opinion of Counsel and an Officers’ Certificate to the effect that such consolidation, merger, sale or conveyance was made in accordance with the provisions of the Indenture and all conditions precedent thereto have been complied with, to the Trustee and satisfactory in form to the Trustee, of Parent and the due and punctual performance of all of the covenants and conditions of the Indenture to be performed by Parent, such successor Person shall succeed to and be substituted for Parent with the same effect as if it had been named herein as a Parent. All the Guarantees so issued shall in all respects have the same legal rank and benefit under the Indenture as the Guarantees theretofore and thereafter issued in accordance with the terms of the Indenture as though all such Guarantees had been issued at the date of the execution hereof.

Notwithstanding the foregoing, Parent may consolidate with, merge into or sell, assign, transfer, convey, lease or otherwise dispose of all or part of its properties and assets to CDW or to another Guarantor.

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 Restricted Subsidiaries of CDW, which properties and assets, if held by CDW instead of such Restricted Subsidiaries, would constitute all or substantially all of the properties and assets of CDW on a consolidated basis, shall be deemed to be the sale, lease, conveyance, assignment, transfer or other disposition of all or substantially all of the properties and assets of CDW.

Although there is a limited body of case law interpreting the phrase “substantially all,” there is no precise established definition of the phrase under applicable law. Accordingly, in certain circumstances there may be a degree of uncertainty as to whether a particular transaction would involve “all or substantially all” of the property or assets of a Person.

Additional Guarantees

CDW shall cause (i) each of its Domestic Subsidiaries (other than any Unrestricted Subsidiary) that incurs any Indebtedness in excess of $50.0 million (other than Indebtedness permitted to be incurred pursuant to the second paragraph of the covenant described under “—Incurrence of Non-Guarantor Indebtedness and Issuance of Non-Guarantor Preferred Stock”) and (ii) each Restricted Subsidiary that guarantees any Indebtedness of CDW or any of the Guarantors, in each case, within ten Business Days of such incurrence of any such Indebtedness or guarantee of such Indebtedness, to execute and deliver to the Trustee a Guarantee (including a supplemental indenture to the Indenture providing for such guarantee), together with an Opinion of Counsel, pursuant to which such Restricted Subsidiary will unconditionally Guarantee, on a joint and several basis, the full and prompt payment of the principal of, premium, if any and interest on the Notes and all other obligations under the Indenture on the same terms and conditions as those set forth in the Indenture.

Each Guarantee will be limited to an amount not to exceed the maximum amount that can be guaranteed by that Restricted Subsidiary without rendering the Guarantee, as it relates to such Restricted Subsidiary, voidable under applicable law relating to fraudulent conveyance or fraudulent transfer or similar laws affecting the rights of creditors generally.

S-29

Each Guarantee shall automatically be released in accordance with the provisions of the Indenture described under “—Guarantees.”

Restrictions on Activities of CDW Finance Corporation

CDW Finance Corporation may not acquire or hold any material assets, voluntarily take any action to become liable for any material obligations or engage in any business activities or operations; provided that CDW Finance Corporation may be a co-obligor with respect to Indebtedness (including, for the avoidance of doubt, the Notes) if CDW is a primary obligor on such Indebtedness, the net proceeds of such Indebtedness are received by CDW or one or more of the Restricted Subsidiaries and such Indebtedness is otherwise permitted to be incurred under the Indenture.

Whether or not required by the Commission, so long as any Notes are outstanding, if not filed electronically with the Commission through the Commission’s Electronic Data Gathering, Analysis, and Retrieval System (or any successor system), CDW will furnish to the Trustee and the Holders, without cost to the Trustee, within the time periods specified in the Commission’s rules and regulations for a filer that is a “non-accelerated filer”:

To the extent any such information is not so filed or furnished, as applicable, within the time periods specified above and such information is subsequently filed or furnished, as applicable, CDW will be deemed to have satisfied its obligations with respect thereto at such time and any Default or Event of Default with respect thereto shall be deemed to have been cured; provided that such cure shall not otherwise affect the rights of the Holders under “—Events of Default and Remedies” if Holders of at least 25% in principal amount of the then total outstanding Notes have declared the principal, premium, if any, interest and any other monetary obligations on all the then-outstanding Notes to be due and payable immediately and such declaration shall not have been rescinded or cancelled prior to such cure.

In addition, if at any time any direct or indirect parent company (other than Parent) becomes a Guarantor (there being no obligation of any such parent company to do so), holds no material assets other than cash, Cash Equivalents and the Capital Stock of CDW or any other direct or indirect parent of CDW (and performs the related incidental activities associated with such ownership) and complies with the requirements of Rule 3-10 of Regulation S-X promulgated by the Commission (or any successor provision, including, for the avoidance of doubt, Rules 13-01 and 13-02 of Regulation S-X promulgated by the Commission), the reports, information and other documents required to be filed and furnished to Holders of the Notes pursuant to this covenant may, at the option of CDW, be filed by and be those of such parent company rather than CDW; provided that the same are accompanied by consolidating information as required by Rule 3-10 of Regulation S-X (or any successor provision, including, for the avoidance of doubt, Rules 13-01 and 13-02 of Regulation S-X promulgated by the Commission) that explains in reasonable detail the differences between the information relating to Parent and such other parent, on the one hand, and the information relating to CDW and its Restricted Subsidiaries on a standalone basis, on the other hand. For the avoidance of doubt, if Parent has made available through the Commission’s Electronic Data Gathering, Analysis, and Retrieval System (or any successor system) the reports, information and other documents required to be filed and furnished to Holders of Notes pursuant to this covenant, CDW shall be deemed to be in compliance with the provisions of this covenant.

S-30

Delivery of the information, documents and other reports described above to the Trustee is for informational purposes only, and the Trustee’s receipt of such shall not constitute constructive or actual notice of any information contained therein or determinable from information contained therein, including the Issuers’ compliance with any of their covenants under the Indenture (as to which the Trustee is entitled to conclusively rely on an Officers’ Certificate). The Trustee shall have no obligation to determine whether or not such information, documents or reports have been filed with the Commission.

Events of Default and Remedies

The following are each an “Event of Default” under the Indenture:

If an Event of Default (other than an Event of Default specified in clause (5) above with respect to the Issuers) shall occur and be continuing, the Trustee acting at the written direction of the Holders of at least 25% in

S-31

aggregate principal amount of the outstanding Notes under the Indenture may declare the principal of the Notes and any accrued interest on the Notes to be due and payable by notice in writing to the Issuers and the Trustee specifying the respective Event of Default and that it is a “notice of acceleration,” and the same shall become immediately due and payable.

Upon such declaration of acceleration, the aggregate principal amount of, and accrued and unpaid interest, if any, on all of the outstanding Notes shall ipso facto become and be immediately due and payable in cash without any declaration or other act on the part of the Trustee or any Holder of the Notes. After such acceleration, but before a judgment or decree based on acceleration, the Holders of a majority in aggregate principal amount of such outstanding Notes may, under certain circumstances, rescind and annul such acceleration if all Events of Default, other than the nonpayment of accelerated principal of or interest on such Notes, have been cured or waived as provided in the Indenture.

The Holders of a majority in principal amount of the outstanding Notes may rescind and cancel such declaration and its consequences:

No such rescission shall affect any subsequent Default or impair any right consequent thereto.

The Holders of a majority in principal amount of the Notes issued and then outstanding under the Indenture may waive any existing Default or Event of Default under the Indenture, and its consequences, except a default in the payment of the principal of or interest on such Notes.

In the event of any Event of Default specified in clause (4) of the first paragraph of this section, such Event of Default and all consequences thereof (excluding, however, any resulting payment default) will be annulled, waived and rescinded, automatically and without any action by the Trustee or the Holders of the Notes, if within 30 days after such Event of Default arose the Issuers deliver an Officers’ Certificate to the Trustee stating that (x) the Indebtedness or guarantee that is the basis for such Event of Default has been discharged, (y) the Holders thereof have rescinded or waived the acceleration, notice or action (as the case may be) giving rise to such Event of Default or (z) the default that is the basis for such Event of Default has been cured, it being understood that in no event shall an acceleration of the principal amount of the Notes as described above be annulled, waived or rescinded upon the happening of any such events.

Holders of the Notes may not enforce the Indenture or such Notes except as provided in such Indenture and under the Trust Indenture Act of 1939, as amended. Subject to the provisions of the Indenture relating to the duties of the Trustee, the Trustee is under no obligation to exercise any of its rights or powers under the Indenture at the request, order or direction of any of the Holders of the Notes, unless such Holders have offered to the Trustee reasonable indemnity satisfactory to the Trustee. Subject to all provisions of the Indenture and applicable law, the Holders of a majority in aggregate principal amount of the then-outstanding Notes issued under the Indenture have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee.

S-32

The Issuers are required to deliver to the Trustee annually a statement regarding compliance with the Indenture. Upon becoming aware of any Default or Event of Default, the Issuers are required to promptly deliver to the Trustee a statement specifying such Default or Event of Default (unless such Default or Event of Default has been cured prior to such time).

No Personal Liability of Directors, Officers, Employees and Stockholders

No director, officer, employee, incorporator, stockholder, unitholder or member of the Issuers, any of their Subsidiaries or any of their direct or indirect parent companies, including Parent, as such, has any liability for any obligations of the Issuers or any Guarantor under the Notes, the Indenture, the Guarantees, or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of Notes by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes. The waiver may not be effective to waive liabilities under the federal securities laws, and it is the view of the Commission that such waiver is against public policy.

Governing Law

Each of the Indenture, the Notes and the Guarantees is governed by, and construed in accordance with, the laws of the State of New York.

Legal Defeasance and Covenant Defeasance

The Issuers may, concurrently and only concurrently, at their option and at any time, elect to have all of their obligations and the obligations of the applicable Guarantors discharged with respect to any outstanding Notes issued under the Indenture (“Legal Defeasance”) except for:

In addition, the Issuers may, at their option and at any time, elect to have their obligations and the obligations of the Guarantors released with respect to certain covenants that are described in the Indenture (“Covenant Defeasance”) and thereafter any omission to comply with those covenants will not constitute a Default or Event of Default with respect to the Notes issued thereunder. In the event that a Covenant Defeasance occurs, certain events (not including nonpayment, bankruptcy, receivership, rehabilitation and insolvency events of the Issuers but including such events with respect to any Significant Subsidiary) described under “—Events of Default and Remedies” will no longer constitute an Event of Default with respect to the Notes issued under the Indenture.

In order to exercise either Legal Defeasance or Covenant Defeasance under an Indenture:

S-33

Amendment, Supplement and Waiver

Except as provided in the next two succeeding paragraphs, the Indenture and the Notes may be amended or supplemented with the consent of the applicable Required Holders (including, without limitation, consents obtained in connection with a purchase of, or tender offer for, such Notes), and any existing default or compliance with any provision of the Indenture and the Notes may be waived (except a default in respect of the payment of principal or interest on such Notes) with the consent of the applicable Required Holders (including, with respect to the Holders of Notes, without limitation, consents obtained in connection with a purchase of, or tender offer for, such Notes).

Without the consent of each affected Holder of Notes, an amendment or waiver of the Indenture may not:

S-34

Notwithstanding the preceding, without the consent of any Holder of the Notes, CDW, the Guarantors and the Trustee may amend or supplement the Indenture, any Guarantee and the Notes issued thereunder:

S-35

Satisfaction and Discharge

The Indenture shall be discharged and will cease to be of further effect as to the Notes issued thereunder, when:

In addition, the Issuers must deliver an Officers’ Certificate and an Opinion of Counsel to the Trustee stating that all conditions precedent to satisfaction and discharge with respect to the Indenture have been satisfied.

Concerning the Trustee

If the Trustee becomes a creditor of CDW, the Indenture limits its right to obtain payment of claims in certain cases, or to realize on certain property received in respect of any such claim as security or otherwise. The Trustee will be permitted to engage in other transactions; however, if it acquires any conflicting interest, it must eliminate such conflict within 90 days or resign.

The Holders of a majority in principal amount of the then-outstanding Notes issued under the Indenture will have the right to direct the time, method and place of conducting any proceeding for exercising any remedy

S-36

available to the Trustee under the Indenture, subject to certain exceptions. The Indenture provides that in case an Event of Default occurs and is continuing, the Trustee will be required, in the exercise of its power, to use the degree of care of a prudent person in the conduct of such person’s 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 of Notes issued thereunder, unless such Holder has offered to the Trustee security and indemnity satisfactory to the Trustee against any loss, liability or expense.

In the event that CDW or any Restricted Subsidiary incurs, assumes, guarantees or repays any Indebtedness or issues or redeems Disqualified Stock or Preferred Stock, in each case subsequent to the commencement of the period for which the Consolidated Non-Guarantor Debt Ratio is being calculated but prior to the event for which the calculation of the Consolidated Non-Guarantor Debt Ratio is made (the “Calculation Date”), then the Consolidated Non-Guarantor Debt Ratio shall be calculated giving pro forma effect to such incurrence, assumption, guarantee or repayment of Indebtedness, or such issuance or redemption of Disqualified Stock or Preferred Stock, as if the same had occurred at the beginning of the applicable four-quarter period and as if CDW or Restricted Subsidiary had not earned the interest income actually earned during such period in respect of such cash used to repay, repurchase, defease or otherwise discharge such Indebtedness.

If Investments, acquisitions, dispositions, mergers or consolidations have been made by CDW or any Restricted Subsidiary during the four-quarter reference period or subsequent to such reference period and on or

S-42

prior to or simultaneously with the Calculation Date, then the Consolidated Non-Guarantor Debt Ratio shall be calculated on a pro forma basis assuming that all such Investments, acquisitions, dispositions, mergers or consolidations (and the change in any associated Fixed Charges and the change in EBITDA resulting therefrom) had occurred on the first day of the four-quarter reference period.

If since the beginning of such period any Person (that subsequently became a Restricted Subsidiary or was merged with or into CDW or any Restricted Subsidiary since the beginning of such period) shall have made any Investment, acquisition, disposition, merger or consolidation that would have required adjustment pursuant to this definition, then the Consolidated Non-Guarantor Debt Ratio shall be calculated giving pro forma effect thereto for such period as if such Investment, acquisition, disposition, merger or consolidation had occurred at the beginning of the applicable four-quarter period.

For purposes of this definition, whenever pro forma effect is to be given to an Investment, acquisition, disposition, merger or consolidation and the amount of income or earnings relating thereto, the pro forma calculations shall be determined in good faith by a responsible financial or accounting Officer of CDW and shall comply with the requirements of Rule 11-02 of Regulation S-X promulgated by the Commission, except that such pro forma calculations may include operating expense reductions for such period resulting from the transaction which is being given pro forma effect that (A) have been realized or (B) for which the steps necessary for realization have been taken (or are taken concurrently with such transaction) or (C) for which the steps necessary for realization are reasonably expected to be taken within the 18 month period following such transaction and, in each case, including, but not limited to, (a) reduction in personnel expenses, (b) reduction of costs related to administrative functions, (c) reduction of costs related to leased or owned properties and (d) reductions from the consolidation of operations and streamlining of corporate overhead; provided that in each case such adjustments are set forth in an Officers’ Certificate signed by CDW’s chief financial officer and another Officer which states (i) the amount of such adjustment or adjustments, (ii) in the case of item (B) or (C) above, that such adjustment or adjustments are based on the reasonable good faith beliefs of the Officers executing such Officers’ Certificate at the time of such execution and (iii) that any related incurrence of Indebtedness is permitted pursuant to the Indenture. If any Indebtedness bears a floating rate of interest and is being given pro forma effect, the interest on such Indebtedness shall be calculated as if the rate in effect on the Calculation Date had been the applicable rate for the entire period (taking into account any Hedging Obligations applicable to such Indebtedness if the related hedge has a remaining term in excess of twelve months).

Interest on a Capitalized Lease Obligation shall be deemed to accrue at the interest rate reasonably determined by a responsible financial or accounting officer of CDW to be the rate of interest implicit in such Capitalized Lease Obligation in accordance with GAAP. For purposes of making the computation referred to above, interest on any Indebtedness under a revolving credit facility computed on a pro forma basis shall be computed based upon the average daily balance of such Indebtedness during the applicable period. Interest on Indebtedness that may optionally be determined at an interest rate based upon a factor of a prime or similar rate, a Eurocurrency interbank offered rate, or other rate, shall be deemed to have been based upon the rate actually chosen, or, if none, then based upon such optional rate chosen as CDW may designate.

“Consolidated Secured Debt Ratio” means, as of any date of determination, the ratio of (a) consolidated total Indebtedness of CDW and its Restricted Subsidiaries on the date of determination that constitutes Secured Indebtedness (other than any Secured Indebtedness that constitutes Non-Guarantor Indebtedness) to (b) the aggregate amount of EBITDA for the then most recent four full fiscal quarters for which internal financial statements of CDW and its Restricted Subsidiaries are available, in each case with such pro forma adjustments as are appropriate and consistent with the pro forma adjustment provisions set forth in the definition of Consolidated Non-Guarantor Debt Ratio.

“Contingent Obligations” means, with respect to any Person, any obligation of such Person guaranteeing or having the economic effect of guaranteeing any leases, dividends or other obligations that do not constitute Indebtedness (“primary obligations”) of any other Person (the “primary obligor”) in any manner, whether

BOOK-ENTRY, DELIVERY AND FORM

The notes will be issued in the form of one or more fully registered global notes which will be deposited with, or on behalf of, DTC and registered in the name of the Cede & Co., DTC’s nominee. Beneficial interests in the global notes will be represented through book-entry accounts of financial institutions acting on behalf of beneficial owners as direct and indirect participants in DTC. Investors may elect to hold interests in the global notes through DTC, Clearstream Banking, société anonyme, Luxembourg (“Clearstream”), or Euroclear Bank S.A./N.V., as operator of the Euroclear System (“Euroclear”) if they are participants of such systems, or indirectly through organizations which are participants in such systems. Clearstream and Euroclear will hold interests on behalf of their participants through customers’ securities accounts in Clearstream’s and Euroclear’s names on the books of their respective depositaries. Clearstream’s and Euroclear’s depositaries will hold interests in customers’ securities accounts in the depositaries’ names on the books of DTC. Except as set forth below, the global notes may be transferred, in whole and not in part, only to another nominee of DTC or to a successor of DTC or its nominee.

DTC has advised us that it is (1) a limited purpose trust company organized under the laws of the State of New York, (2) a “banking organization” within the meaning of the New York Banking Law, (3) a member of the Federal Reserve System, (4) a “clearing corporation” within the meaning of the Uniform Commercial Code, as amended and (5) a “clearing agency” registered pursuant to Section 17A of the Exchange Act. DTC was created to hold securities for its participants and facilitates the clearance and settlement of securities transactions between participants through electronic book-entry changes to the accounts of its participants, thereby eliminating the need for physical transfer and delivery of certificates. DTC’s participants include securities brokers and dealers, including the underwriters, banks and trust companies, clearing corporations and certain other organizations. Indirect access to DTC’s system is also available to other entities such as banks, brokers, dealers and trust companies, referred to as “indirect participants,” that clear through or maintain a custodial relationship with a participant, either directly or indirectly. Investors who are not participants may beneficially own securities held by or on behalf of DTC only through participants or indirect participants.

According to DTC, the foregoing information with respect to DTC has been provided to the financial community for informational purposes only and is not intended to serve as a representation, warranty or contract modification of any kind. We make no representation as to the accuracy or completeness of such information.

Clearstream has advised that it is incorporated under the laws of the Grand Duchy of Luxembourg as a professional depositary. Clearstream holds securities for its participating organizations (“Clearstream participants”). Clearstream facilitates the clearance and settlement of securities transactions between Clearstream participants through electronic book-entry changes in accounts of Clearstream participants, eliminating the need for physical movement of certificates. Clearstream provides to Clearstream participants, among other things, services for safekeeping, administration, clearance and settlement of internationally traded securities and securities lending and borrowing. Clearstream interfaces with domestic markets in several countries. As a professional depositary, Clearstream is subject to regulation by the Luxembourg Commission for the Supervision of the Financial Sector (CSSF). Clearstream participants are recognized financial institutions around the world, including underwriters, securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations. Indirect access to Clearstream is also available to others, such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a Clearstream participant, either directly or indirectly.

Distributions, to the extent received by the U.S. Depositary for Clearstream, with respect to the notes held beneficially through Clearstream will be credited to cash accounts of Clearstream participants in accordance with its rules and procedures.

Euroclear has advised that it was created in 1968 to hold securities for its participants (“Euroclear participants”) and to clear and settle transactions between Euroclear participants through simultaneous electronic

S-58

book-entry delivery against payment, eliminating the need for physical movement of certificates and eliminating any risk from lack of simultaneous transfers of securities and cash. Euroclear provides various other services, including securities lending and borrowing and interfaces with domestic markets in several countries. Euroclear is operated by Euroclear Bank S.A./N.V. (the “Euroclear Operator”), under contract with Euroclear Clearance Systems S.C., a Belgian cooperative corporation (the “Cooperative”). All operations are conducted by the Euroclear Operator, and all Euroclear securities clearance accounts and Euroclear cash accounts are accounts with the Euroclear Operator not the Cooperative. The Cooperative establishes policy for Euroclear on behalf of Euroclear participants. Euroclear participants include banks (including central banks), securities brokers and dealers and other professional financial intermediaries and may include the underwriters. Indirect access to Euroclear is also available to other firms that clear through or maintain a custodial relationship with a Euroclear participant, either directly or indirectly.

The Euroclear Operator has advised us that it is licensed by the Belgian Banking and Finance Commission to carry out banking activities on a global basis. As a Belgian bank, it is regulated and examined by the Belgian Banking Commission.

Securities clearance accounts and cash accounts with the Euroclear Operator are governed by the Terms and Conditions Governing Use of Euroclear and the related Operating Procedures of the Euroclear System, and applicable Belgian law (collectively, the “Terms and Conditions”). The Terms and Conditions govern transfers of securities and cash within Euroclear, withdrawals of securities and cash from Euroclear, and receipts of payments with respect to securities in Euroclear. All securities in Euroclear are held on a fungible basis without attribution of specific certificates to specific securities clearance accounts. The Euroclear Operator acts under the Terms and Conditions only on behalf of Euroclear participants, and has no record of or relationship with persons holding through Euroclear participants.

Distributions, to the extent received by the U.S. Depositary for Euroclear, with respect to notes held beneficially through Euroclear will be credited to the cash accounts of Euroclear participants in accordance with the Terms and Conditions.

If (1) we notify the trustee in writing that DTC, Euroclear or Clearstream is no longer willing or able to act as a depositary or clearing system for the notes or DTC ceases to be registered as a clearing agency under the Exchange Act, and a successor depositary or clearing system is not appointed within 90 days of this notice or cessation, (2) we, at our option, notify the trustee in writing that we elect to cause the issuance of the notes in definitive form under the indenture or (3) upon the occurrence and continuation of an event of default under the indenture with respect to the notes, then, upon surrender by DTC of the global notes, certificated notes will be issued to each person that DTC identifies as the beneficial owner of the notes represented by the global notes. Upon any such issuance, the trustee is required to register the certificated notes in the name of the person or persons or the nominee of any of these persons and cause the same to be delivered to these persons. Neither we nor the trustee shall be liable for any delay by DTC or any participant or indirect participant in identifying the beneficial owners of the related notes and each such person may conclusively rely on, and shall be protected in relying on, instructions from DTC for all purposes, including with respect to the registration and delivery, and the respective principal amounts, of the notes to be issued.

Title to book-entry interests in the global notes will pass by book-entry registration of the transfer within the records of DTC, Clearstream or Euroclear in accordance with their respective procedures. Book-entry interests in the global notes may be transferred within DTC in accordance with procedures established for this purpose by DTC. Book-entry interests in the notes may be transferred within Euroclear and within Clearstream and between Euroclear and Clearstream in accordance with procedures established for these purposes by Euroclear and Clearstream. Transfers of book-entry interests in the notes between Euroclear and Clearstream and DTC may be effected in accordance with procedures established for this purpose by Euroclear, Clearstream and DTC.

S-59

Global Clearance and Settlement Procedures

Subject to compliance with the transfer restrictions applicable to the notes, cross-market transfers between the participants in DTC, on the one hand, and Euroclear or Clearstream participants, on the other hand, will be effected through DTC in accordance with DTC’s rules on behalf of Euroclear or Clearstream, as the case may be, by its respective depositary; however, such cross-market transactions will require delivery of instructions to Euroclear or Clearstream, as the case may be, by the counterparty in the system in accordance with the rules and procedures and within the established deadlines (Brussels time) of the system. Euroclear or Clearstream, as the case may be, will, if the transaction meets its settlement requirements, deliver instructions to its respective depositary to take action to effect final settlement on its behalf by delivering or receiving interests in the relevant global notes in DTC, and making or receiving payment in accordance with normal procedures for same-day funds settlement applicable to DTC. Euroclear participants and Clearstream participants may not deliver instructions directly to the depositaries for Euroclear or Clearstream.

Because of time-zone differences, credits of notes received in Clearstream or Euroclear as a result of a transaction with a DTC participant will be made during subsequent notes settlement processing and dated the business day following the DTC settlement date. Credits or any transactions of the type described above settled during subsequent notes settlement processing will be reported to the relevant Euroclear or Clearstream participants on the business day that the processing occurs. Cash received in Clearstream or Euroclear as a result of sales of the notes by or through a Clearstream participant or a Euroclear participant to a DTC participant will be received with value on the DTC settlement date but will be available in the relevant Clearstream or Euroclear cash account only as of the business day following settlement in DTC.

Although DTC, Clearstream and Euroclear have agreed to the foregoing procedures in order to facilitate transfers of the notes among participants of DTC, Clearstream and Euroclear, they are under no obligation to perform or continue to perform these procedures. The foregoing procedures may be changed or discontinued at any time. Neither we nor the trustee will have any responsibility for the performance by DTC, Euroclear or Clearstream or their respective participants or indirect participants of their respective obligations under the rules and procedures governing their operations.

CERTAIN U.S. FEDERAL INCOME TAX CONSIDERATIONS

The following is a general discussion of certain U.S. federal income tax considerations relating to the purchase, ownership and disposition of the notes. This discussion is based on current provisions of the Internal Revenue Code of 1986, as amended (the “Code”), Treasury regulations promulgated thereunder, and administrative and judicial interpretations thereof, all as in effect or in existence on the date hereof, and all of which are subject to change or different interpretation, possibly with retroactive effect. No rulings have been sought or are expected to be sought from the Internal Revenue Service (the “IRS”) with respect to any of the tax consequences discussed below, and no assurance can be given that the IRS will not successfully assert contrary positions.

This discussion only addresses U.S. federal income tax considerations for beneficial owners of the notes who hold the notes as “capital assets,” within the meaning of the Code and who purchase them in this offering at the “issue price” (i.e. the first price at which a substantial amount of notes is sold for cash (excluding sales to underwriters or persons acting in a similar capacity).

This discussion is for general information only and does not address all of the U.S. federal income tax considerations that may be relevant to specific beneficial owners of the notes in light of their particular circumstances (such as beneficial owners that are treated as being related to us for U.S. federal income tax purposes) or to beneficial owners of the notes that are subject to special treatment under U.S. federal income tax laws (such as banks or other financial institutions, insurance companies, partnerships or S corporations for U.S. federal income tax purposes (or investors in such entities), tax-exempt entities, retirement plans, dealers in securities or currencies, brokers, traders in securities that have elected the mark-to-market method of accounting for their securities, holders that have made an election to include in gross income all interest on a note under the constant yield method, real estate investment trusts, regulated investment companies, persons who hold their notes as part of a straddle, hedge, conversion transaction or other integrated investment, U.S. holders (as defined below) whose functional currency is not the U.S. dollar, persons subject to special tax accounting rules as a result of any item of gross income with respect to the notes being taken into account in an applicable financial statement (as defined in section 451 of the Code), controlled foreign corporations, passive foreign investment companies, U.S. holders that hold notes through non-U.S. brokers or other non-U.S. intermediaries, or U.S. expatriates). This discussion does not address alternative minimum taxes, the base erosion and anti-abuse tax, U.S. state or local tax considerations, U.S. federal tax laws other than income tax laws (such as the Medicare tax on certain investment income or estate and gift tax laws), or non-U.S. tax considerations. Further this discussion does not address any consequences that may result pursuant to Treasury regulations promulgated under section 385 of the Code with respect to any holder that is considered related to the Issuers for the purposes of such regulations.

If an entity or arrangement treated as a partnership for U.S. federal income tax purposes holds the notes, the tax treatment of such partnership and each partner will depend upon the status and the activities of the partnership and the partner. If you are a partnership or a partner in a partnership considering an investment in the notes, we urge you to consult your tax advisors.

WE URGE PROSPECTIVE BENEFICIAL OWNERS TO CONSULT THEIR TAX ADVISORS FOR ANALYSIS OF THE PARTICULAR TAX CONSIDERATIONS APPLICABLE TO THEM AS A RESULT OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF THE NOTES, INCLUDING THE APPLICABILITY OF ANY U.S. FEDERAL, STATE, AND LOCAL TAX LAWS OR NON-U.S. TAX LAWS, ANY CHANGES IN APPLICABLE TAX LAWS, AND ANY PENDING OR PROPOSED LEGISLATION OR REGULATIONS.

S-61

Effect of Certain Additional Payments

In certain circumstances, including certain changes of control, we are required to make payments on the notes in addition to stated principal and interest or to make payments in advance of their scheduled times. See “Description of Notes—Repurchase at the Option of Holders—Change of Control.” Such contingencies may cause the notes to be treated as contingent payment debt instruments, in which case the timing and amount of income inclusions and the character of income recognized may be different from the consequences discussed herein. The Treasury regulations regarding debt instruments that provide for one or more contingent payments state that, for purposes of determining whether a debt instrument is a contingent payment debt instrument, remote or incidental contingencies (and certain other contingencies) are ignored. We believe that the foregoing contingencies, in the aggregate, are remote or incidental (or that certain other exceptions apply), and, accordingly, we intend to take the position that the notes are not contingent payment debt instruments. Our determination will be binding on all holders, except a holder that discloses its differing position in a statement attached to its timely filed U.S. federal income tax return for the taxable year during which a note was acquired. Our determination is not, however, binding on the IRS, and if the IRS were to challenge such determination, a holder might be required to accrue ordinary income on the notes at a rate in excess of the stated interest rate, and to treat as ordinary income, rather than capital gain, any income recognized on the taxable disposition of a note. In the event a contingency actually occurs, it may affect the amount and timing (and possibly character) of the income that a holder will recognize. The discussion below assumes that our determination that these contingencies are remote or incidental is correct and assumes that the notes will not be treated as contingent payment debt instruments.

Certain U.S. Federal Income Tax Considerations for U.S. Holders

For purposes of this discussion, “U.S. holder” means a beneficial owner of a note that is, for U.S. federal income tax purposes:

Taxation of Stated Interest

Generally, payments of stated interest on the notes will be taxable as ordinary income as received or accrued in accordance with the U.S. holder’s regular method of accounting for U.S. federal income tax purposes.

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

Upon the sale, exchange, retirement, redemption or other taxable disposition of a note, a U.S. holder generally will recognize gain or loss equal to the difference, if any, between (A) the amount of cash and the fair market value of all other property received on the disposition (other than any such amount attributable to accrued and unpaid stated interest, which will be taxed as ordinary income to the extent not previously so taxed) and (B) the U.S. holder’s “adjusted tax basis” in the note. A U.S. holder’s adjusted tax basis in a note generally will equal the amount paid for the note determined at the time of purchase.

Any gain or loss that a U.S. holder recognizes upon the sale, exchange, retirement, redemption or other taxable disposition of a note generally will be capital gain or loss and will be long-term capital gain or loss if, at

S-62

the time of the disposition, the U.S. holder’s holding period for the note is more than one year. Long-term capital gains recognized by an individual or other non-corporate U.S. holder generally are subject to a reduced rate of U.S. federal income tax. Capital losses are subject to limits on deductibility.

Information Reporting and Backup Withholding

Information reporting will apply to stated interest paid on, and the proceeds of the sale, exchange, retirement, redemption or other taxable disposition of, a note held by a U.S. holder unless such holder establishes an exemption from information reporting. Backup withholding may also apply (currently, at a rate of 24%) unless such holder establishes an exemption by providing the appropriate intermediary with a taxpayer identification number, certified under penalties of perjury, as well as certain other information (generally, on IRS Form W-9) or otherwise establishes an exemption. Any amount withheld under the backup withholding rules is allowable as a credit against a U.S. holder’s U.S. federal income tax liability, if any, and a refund may be obtained if the amounts withheld exceed such holder’s actual U.S. federal income tax liability and such holder timely provides the required information or appropriate claim form to the IRS.

Certain U.S. Federal Income Tax Considerations for Non-U.S. Holders

For purposes of this discussion, “non-U.S. holder” means a beneficial owner of a note that is, for U.S. federal income tax purposes, an individual, corporation, estate or trust that is not a U.S. holder.

For purposes of the following discussion, interest on the notes, and gain on the sale, exchange, retirement, redemption or other taxable disposition of the notes, will be considered “U.S. trade or business income” of a non-U.S. holder if such income or gain is effectively connected with the conduct of a trade or business in the United States by such non-U.S. holder.

Taxation of Interest

Subject to the discussion below concerning backup withholding and FATCA legislation, a non-U.S. holder will not be subject to U.S. federal income or withholding tax in respect of interest paid on the notes if the interest qualifies for the “portfolio interest exemption.” This will be the case if each of the following requirements is satisfied:

The certification requirement generally will be satisfied if the non-U.S. holder provides the withholding agent with a statement on IRS Form W-8BEN or IRS Form W-8BEN-E (or suitable substitute form), together with all appropriate attachments, signed under penalties of perjury, identifying the non-U.S. holder and stating, among other things, that the non-U.S. holder is not a United States person. Prospective non-U.S. holders should consult their tax advisors regarding alternative methods for satisfying the certification requirement.

If the requirements of the portfolio interest exemption are not satisfied with respect to a non-U.S. holder, a 30% U.S. federal income withholding tax will apply to interest paid on the notes to such non-U.S. holder, unless another exemption is applicable. For example, an applicable income tax treaty may reduce or eliminate such tax,

S-63

in which event a non-U.S. holder claiming the benefit of such treaty must provide the withholding agent with a properly executed IRS Form W-8BEN or IRS Form W-8BEN-E (or suitable substitute form). Alternatively, an exemption applies if the interest is U.S. trade or business income of the non-U.S. holder and the non-U.S. holder provides the withholding agent with a properly executed IRS Form W-8ECI (or suitable substitute form). If the interest is U.S. trade or business income of a non-U.S. holder, such non-U.S. holder generally will be subject to U.S. federal income tax with respect to all interest on the notes in the same manner as U.S. holders, as described above, unless an applicable income tax treaty provides otherwise. Additionally, non-U.S. holders that are corporations generally will be subject to a branch profits tax with respect to any earnings and profits attributable to such U.S. trade or business (subject to adjustments) at a rate of 30% (or at a reduced rate under an applicable income tax treaty).

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

Subject to the discussion below concerning backup withholding and FATCA legislation, generally, a non-U.S. holder will not be subject to U.S. federal income tax on any gain recognized on the sale, exchange, retirement, redemption or other taxable disposition of a note, unless (i) such non-U.S. holder is an individual who is present in the United States for 183 days or more in the taxable year of the sale, exchange, retirement, redemption or other taxable disposition and certain other conditions are met or (in which case such gain will be subject to U.S. federal income tax at a rate of 30% (or lower applicable treaty rate)) or (ii) the gain is U.S. trade or business income of the non-U.S. holder. If the gain is U.S. trade or business income of the non-U.S. holder, the non-U.S. holder generally will be subject to U.S. federal income tax with respect to such gain in the same manner as U.S. holders, as described above, unless an applicable income tax treaty provides otherwise. Additionally, non-U.S. holders that are corporations generally will be subject to a branch profits tax with respect to any earnings and profits attributable to such U.S. trade or business (subject to adjustments) at a rate of 30% (or at a reduced rate under an applicable income tax treaty).

To the extent the proceeds from the sale, exchange, retirement, redemption or other taxable disposition of a note represent accrued and unpaid interest, the non-U.S. holder generally will be subject to U.S. federal income tax with respect to such accrued and unpaid interest in the same manner as described above under “Taxation of Interest.”

Information Reporting and Backup Withholding

Amounts of interest paid to a non-U.S. holder on a note, and amounts withheld from such payments, if any, generally will be required to be reported to the IRS and to such holder.

U.S. backup withholding (currently at a rate of 24%) generally will not apply to payments of interest on a note to a non-U.S. holder if the statement described above under “Taxation of Interest” is duly provided by such holder or such holder otherwise establishes an exemption.

Payments to a non-U.S. holder of the proceeds of a sale, exchange, retirement, redemption or other taxable disposition of a note effected by the U.S. office of a U.S. or foreign broker will be subject to information reporting requirements and backup withholding unless such holder properly certifies under penalties of perjury as to such holder’s non-U.S. status and certain other conditions are met or such holder otherwise establishes an exemption. Backup withholding generally will not apply to any payment to a non-U.S. holder of the proceeds of the disposition of a note effected outside the United States by a non-U.S. office of a broker. However, unless such a broker has documentary evidence in its records as to such non-U.S. holder’s non-U.S. status and certain other conditions are met, or such holder otherwise establishes an exemption, information reporting will apply to a payment of the proceeds of the disposition of a note effected outside the United States by such a broker if the broker:

S-64

Any amount withheld under the backup withholding rules is allowable as a credit against a non-U.S. holder’s U.S. federal income tax liability, if any, and a refund may be obtained if amounts withheld exceed such holder’s actual U.S. federal income tax liability and if the proper information is timely provided to the IRS.

Legislation Affecting Taxation of Notes Held by or Through Foreign Entities

Sections 1471 through 1474 of the Code (the “FATCA legislation”) generally impose a U.S. federal withholding tax of 30% on interest income paid on a debt obligation to (i) a foreign financial institution (as the beneficial owner or as an intermediary for the beneficial owner), unless such institution enters into an agreement with the U.S. government to collect and provide to the U.S. tax authorities substantial information regarding U.S. account holders of such institution (which would include certain equity and debt holders of such institution, as well as certain account holders that are foreign entities with U.S. owners), and (ii) a foreign entity that is not a financial institution (as the beneficial owner or as an intermediary for the beneficial owner), unless such entity provides the withholding agent with a certification identifying the substantial U.S. owners of the entity, which generally includes any U.S. person who directly or indirectly owns more than 10% of the entity. The FATCA legislation initially imposed a withholding tax on gross proceeds from a sale, exchange, retirement, redemption or other taxable disposition of the notes. However, proposed Treasury Regulations, which state that taxpayers may rely on the proposed regulations until final regulations are issued, provide that this withholding tax shall not apply to gross proceeds from a sale or other taxable disposition of the Notes. An intergovernmental agreement between the U.S. and the applicable foreign country, or future Treasury regulations or other guidance, may modify these requirements. Investors are strongly encouraged to consult with their own tax advisors regarding the implications of this FATCA legislation on their investment in our notes.

UNDERWRITING

Morgan Stanley & Co. LLC is acting as representative of each of the underwriters named below. Subject to the terms and conditions in the underwriting agreement dated the date of this prospectus supplement between us and the underwriters, we have agreed to sell, and the underwriters named below have severally and not jointly agreed to purchase, the following respective principal amounts of the notes.

Subject to the terms and conditions set forth in the underwriting agreement, the underwriters have agreed, severally and not jointly, to purchase all of the notes sold under the underwriting agreement if any of the notes are purchased. The underwriting agreement provides that if an underwriter defaults with respect to the notes the purchase commitments of non-defaulting underwriters may be increased or the offering of the notes may be terminated.

The underwriters initially propose to offer the notes for resale at the issue price that appears on the cover of this prospectus supplement. Any notes sold by the underwriters to securities dealers may be sold at a discount from the initial public offering price and any such securities dealers may resell any notes purchased from the underwriters to certain other brokers or dealers at a discount from the initial public offering price. After the initial offering, the underwriters may change the offering price and any other selling terms. The underwriters may offer and sell notes through certain of their affiliates.

We have agreed that we will not offer, sell, contract to sell, pledge or otherwise dispose of, directly or indirectly, or file with the SEC a registration statement under the Securities Act of 1933 (the “Securities Act”) relating to, any additional debt securities, or publicly disclose the intention to make any such offer, sale, pledge, disposition or filing, without the prior written consent of Morgan Stanley & Co. LLC until 60 days following the settlement date for the notes.

We will pay our out-of-pocket expenses related to the offering, which we estimate will be approximately $1.5 million.                

We have agreed to indemnify the several underwriters against liabilities under the Securities Act, or contribute to payments which the underwriters may be required to make in that respect.

The notes are a new issue of securities with no established trading market. One or more of the underwriters intend to make a secondary market for the notes. However, they are not obligated to do so and may discontinue making a secondary market for the notes at any time without notice. No assurance can be given as to how liquid the trading market for the notes will be.

S-66

In connection with the offering, the underwriters may engage in stabilizing transactions, over-allotment transactions and syndicate covering transactions in accordance with Regulation M under the Exchange Act.

These stabilizing transactions and syndicate covering transactions may have the effect of raising or maintaining the market price of the notes or preventing or retarding a decline in the market price of the notes. As a result the price of the notes may be higher than the price that might otherwise exist in the open market. These transactions, if commenced, may be discontinued at any time.

Conflicts of Interest; Other Relationships

The underwriters and their respective affiliates are full service financial institutions engaged in various activities, which may include securities trading, commercial and investment banking, financial advisory, investment management, investment research, principal investment, hedging, financing and brokerage activities. Certain of the underwriters and their respective affiliates have, from time to time, performed, and may in the future perform, various financial advisory and investment banking services for us, for which they may receive customary fees and expenses. In particular, certain of the underwriters and/or their respective affiliates are parties to and lenders under our ABL Facility and Term Loan Facility. Each of our ABL Facility and Term Loan Facility was negotiated on an arm’s length basis and contains customary terms pursuant to which the lenders receive customary fees. In addition, U.S. Bancorp Investments, Inc., one of the underwriters, is an affiliate of the trustee.

In the ordinary course of their various business activities, certain of the underwriters and their respective affiliates have made or held, and may in the future make or hold, a broad array of investments including serving as counterparties to certain derivative and hedging arrangements, and may have actively traded, and, in the future may actively trade, debt and equity securities (or related derivative securities), and financial instruments (including bank loans) for their own account and for the accounts of their customers. Such investment and securities activities may have involved, and in the future may involve, securities and instruments of our company. If any of the underwriters or their affiliates has a lending relationship with us, certain of those underwriters or their affiliates routinely hedge, and certain other of those underwriters or their affiliates may hedge, their credit exposure to us consistent with their customary risk management policies. Typically, these underwriters and their affiliates would hedge such exposure by entering into transactions which consist of either the purchase of credit default swaps or the creation of short positions in our securities, including potentially the notes offered hereby. Any such credit default swaps or short positions could adversely affect future trading prices of the notes offered hereby. The underwriters and their affiliates may also make investment recommendations and/or publish or express independent research views in respect of such securities or financial instruments and may hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments. Certain of the underwriters and/or their respective affiliates own a portion of the 2025 Senior Notes for their own account and will therefore receive a portion of the net proceeds from this offering used to redeem the 2025 Senior Notes.

Canada

The notes may be sold only to purchasers purchasing, or deemed to be purchasing, as principal that are accredited investors, as defined in National Instrument 45-106 Prospectus Exemptions or subsection 73.3(1) of the Securities Act (Ontario), and are permitted clients, as defined in National Instrument 31-103 Registration

S-67

Requirements, Exemptions and Ongoing Registrant Obligations. Any resale of the notes must be made in accordance with an exemption from, or in a transaction not subject to, the prospectus requirements of applicable securities laws.

The purchaser should refer to any applicable provisions of the securities legislation of the purchaser’s province or territory for particulars of these rights or consult with a legal advisor.

Pursuant to section 3A.3 of National Instrument 33-105 Underwriting Conflicts (NI 33-105), the underwriters are not required to comply with the disclosure requirements of NI 33-105 regarding underwriter conflicts of interest in connection with this offering.

No key information document required by Regulation (EU) No 1286/2014, as amended (the “PRIIPs Regulation”) for offering or selling the notes or otherwise making them available to retail investors in the EEA or in the United Kingdom has been prepared. Offering or selling the notes or otherwise making them available to any retail investor in the EEA or the United Kingdom may be unlawful under the PRIIPs Regulation. This offering memorandum has been prepared on the basis that any offer of notes in any Member State of the EEA or the United Kingdom will be made pursuant to an exemption under the Prospectus Regulation from the requirement to publish a prospectus for offers of notes.

You should carefully consider and evaluate all of the information included and incorporated by reference in this prospectus, including the risk factors incorporated by reference from our most recent Annual Report on Form 10-K. Our business, financial condition, liquidity or results of operations could be materially adversely affected by any of these risks.

USE OF PROCEEDS

Unless otherwise indicated in the applicable prospectus supplement, we will use the net proceeds from the sale of the securities for general corporate purposes, which may include capital expenditures, working capital, acquisitions, investments and the repayment of indebtedness.

RATIO OF EARNINGS TO FIXED CHARGES

The following table sets forth our historical ratios of earnings to fixed charges for the periods indicated. This information should be read in conjunction with the consolidated financial statements and the accompanying notes incorporated by reference in this prospectus.

For purposes of calculating the ratio of earnings to fixed charges, earnings consist of earnings before income taxes minus income from equity investments plus fixed charges. Fixed charges consist of interest expense and the portion of rental expense we believe is representative of the interest component of rental expense. This summary is qualified by the more detailed information appearing in the computation table found in Exhibit 12.1 to the registration statement of which this prospectus is a part.

Because we have not issued any preferred stock to date, the ratios of earnings to fixed charges and preferred stock dividend requirements are identical to the ratios shown above.

DESCRIPTION OF CAPITAL STOCK

The following summary of certain provisions of our capital stock does not purport to be complete and is subject to our amended and restated certificate of incorporation, our amended and restated bylaws and provisions of applicable law. Copies of our amended and restated certificate of incorporation and amended and restated bylaws are incorporated by reference into the registration statement, of which this prospectus is a part.

Authorized Capitalization

As of the date of this prospectus, our authorized capital stock consists of 1,000,000,000 shares of common stock, par value $0.01 per share, and 100,000,000 shares of undesignated preferred stock, par value $0.01 per share. As of September 30, 2017, we have 152,942,551 shares of common stock and no shares of preferred stock outstanding. The number of shares of our common stock authorized will be unaffected by the offerings under this prospectus.

Common Stock Voting Rights

Each holder of our common stock is entitled to one vote per share on each matter submitted to a vote of stockholders. Our amended and restated bylaws provide that the presence, in person or by proxy, of holders of shares representing a majority of the outstanding shares of capital stock entitled to vote at a stockholders’ meeting shall constitute a quorum. When a quorum is present, the affirmative vote of a majority of the votes cast is required to take action, unless otherwise specified by law or our amended and restated certificate of incorporation. There are no cumulative voting rights.

Common Stock Dividend Rights

Each holder of shares of our capital stock is entitled to receive such dividends and other distributions in cash, stock or property as may be declared by our board of directors from time to time out of our assets or funds legally available for dividends or other distributions. These rights are subject to the preferential rights of any other class or series of our preferred stock that we may designate and issue in the future.

The General Corporation Law of the State of Delaware (the “DGCL”) permits a corporation to declare and pay dividends out of “surplus” or, if there is no “surplus,” out of its net profits for the fiscal year in which the dividend is declared and/or the preceding fiscal year. “Surplus” is defined as the excess of the net assets of the corporation over the amount determined to be the capital of the corporation by the board of directors. The capital of the corporation is typically calculated to be (and cannot be less than) the aggregate par value of all issued shares of capital stock. Net assets equals the fair value of the total assets minus total liabilities. The DGCL also provides that dividends may not be paid out of net profits if, after the payment of the dividend, remaining capital would be less than the capital represented by the outstanding stock of all classes having a preference upon the distribution of assets.

Declaration and payment of any dividend will be subject to the discretion of our board of directors. The time and amount of dividends will be dependent upon our results of operations, financial condition, business prospects, capital requirements, contractual restrictions, any potential indebtedness we may incur, the provisions of Delaware law affecting the payment of distributions to stockholders, tax considerations and other factors that our board of directors deems relevant. In addition, our ability to pay dividends on our common stock will be limited by restrictions on our ability to pay dividends or make distributions to our stockholders and on the ability of our subsidiaries to pay dividends or make distributions to us, in each case, under the terms of our current and any future agreements governing our indebtedness.

Since the fourth quarter of 2013, we have paid a quarterly cash dividend on our common stock and we currently expect to continue to pay a cash dividend on our common stock. However, any determination to pay dividends in the future will be at the discretion of our board of directors.

3

Other Rights

Each holder of common stock is subject to, and may be adversely affected by, the rights of the holders of any series of preferred stock that we may designate and issue in the future. Holders of common stock will have no preemptive, conversion or other rights to subscribe for additional shares.

Liquidation Rights

In the event of any voluntary or involuntary liquidation, dissolution or winding up of our affairs, holders of our common stock would be entitled to share ratably in our assets that are legally available for distribution to stockholders after payment of our debts and other liabilities. If we have any preferred stock outstanding at such time, holders of the preferred stock may be entitled to distribution and/or liquidation preferences. In either such case, we must pay the applicable distribution to the holders of our preferred stock before we may pay distributions to the holders of our common stock.

Preferred Stock

Our board of directors has the authority to issue shares of preferred stock from time to time on terms it may determine, to divide shares of preferred stock into one or more series and to fix the designations, preferences, privileges and restrictions of preferred stock, including dividend rights, conversion rights, voting rights, terms of redemption, liquidation preference, sinking fund terms and the number of shares constituting any series or the designation of any series to the fullest extent permitted by the DGCL. The issuance of our preferred stock could have the effect of decreasing the trading price of our common stock, restricting dividends on our capital stock, diluting the voting power of our common stock, impairing the liquidation rights of our capital stock, or delaying or preventing a change in control of our company. At present, we have no plans to issue preferred stock.

Anti-Takeover Effects of Our Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws

Our amended and restated certificate of incorporation and our amended and restated bylaws contain provisions that may delay, defer or discourage another party from acquiring control of us. We expect that these provisions, which are summarized below, will discourage coercive takeover practices or inadequate takeover bids. These provisions are also designed to encourage persons seeking to acquire control of us to first negotiate with our board of directors, which we believe may result in an improvement of the terms of any such acquisition in favor of our stockholders. However, they also give the board of directors the power to discourage acquisitions that some stockholders may favor.

Undesignated Preferred Stock

The ability to authorize undesignated preferred stock will make it possible for our board of directors to issue preferred stock with super voting, special approval, dividend or other rights or preferences on a discriminatory basis that could impede the success of any attempt to acquire us. These and other provisions may have the effect of deferring, delaying or discouraging hostile takeovers, or changes in control or management of our company.

Classified Board of Directors

Our amended and restated certificate of incorporation provides that our board of directors will be divided into three classes, with each class serving three-year staggered terms. In addition, directors serving on our classified board of directors may only be removed from the board of directors with cause and by an affirmative vote of two-thirds of our common stock. These provisions may have the effect of deferring, delaying or discouraging hostile takeovers, or changes in control or management of our company.

4

Stockholder Action by Written Consent

Our amended and restated certificate of incorporation provides that any action required or permitted to be taken by our stockholders may be effected only at a duly called annual or special meeting of the stockholders and cannot be taken by written consent in lieu of a meeting.

Special Meeting of Stockholders and Advance Notice Requirements for Stockholder Proposals

Our amended and restated certificate of incorporation and amended and restated bylaws provide that, except as otherwise required by law, special meetings of the stockholders can only be called by or at the direction of our board of directors pursuant to a written resolution adopted by the affirmative vote of the majority of the total number of directors that we would have if there were no vacancies.

In addition, our amended and restated bylaws require advance notice procedures for stockholder proposals to be brought before an annual meeting of the stockholders, including the nomination of directors. Stockholders at an annual meeting may only consider the proposals specified in the notice of meeting or brought before the meeting by or at the direction of the board of directors, or by a stockholder of record on the record date for the meeting, who is entitled to vote at the meeting and who has delivered a timely written notice, in proper form to our secretary, of the stockholder’s intention to bring such business before the meeting.

These provisions could have the effect of delaying until the next stockholder meeting any stockholder actions, even if they are favored by the holders of a majority of our outstanding voting securities.

Amendment to Certificate of Incorporation and Bylaws

The DGCL provides generally that the affirmative vote of a majority of the outstanding stock entitled to vote on amendments to a corporation’s certificate of incorporation or bylaws is required to approve such amendment, unless a corporation’s certificate of incorporation or bylaws, as the case may be, requires a greater percentage. Our amended and restated bylaws may be amended or repealed by a majority vote of our board of directors or, in addition to any other vote otherwise required by law, the affirmative vote of at least a majority of the voting power of our outstanding shares of common stock. Our amended and restated certificate of incorporation provides that the affirmative vote of at least two-thirds of the voting power of the outstanding shares of capital stock entitled to vote on the adoption, alteration, amendment or repeal of our amended and restated certificate of incorporation, voting as a single class, is required to amend or repeal or to adopt any provision inconsistent with the “Stockholder Action by Written Consent,” “Special Meetings of Stockholders and Advance Notice Requirements for Stockholder Proposals,” “Amendments to Certificate of Incorporation and Bylaws” and “Business Combinations with Interested Stockholders” provisions contained in our amended and restated certificate of incorporation. These provisions may have the effect of deferring, delaying or discouraging the removal of any anti-takeover defenses provided for in our amended and restated certificate of incorporation and our amended and restated bylaws. Our amended and restated certificate of incorporation also provides that the provision of our amended and restated certificate of incorporation that deals with corporate opportunity may only be amended, altered or repealed by a vote of 80% of the voting power of our then-outstanding capital stock entitled to vote generally in the election of directors, voting as a single class.

Business Combinations with Interested Stockholders

We elect in our amended and restated certificate of incorporation not to be subject to Section 203 of the DGCL, an anti-takeover law. In general, Section 203 prohibits a publicly held Delaware corporation from engaging in a business combination, such as a merger, with a person or group owning 15% or more of the corporation’s voting stock for a period of three years following the date the person became an interested stockholder, unless (with certain exceptions) the business combination or the transaction in which the person became an interested stockholder is approved in a prescribed manner. Accordingly, we will not be subject to any anti-takeover effects of Section 203. However, our amended and restated certificate of incorporation contains provisions that have substantially the same effect as Section 203.

5

Corporate Opportunity

Our amended and restated certificate of incorporation provides that we renounce any interest or expectancy in, or in being offered an opportunity to participate in, any business opportunity that may from time to time be presented to our former sponsors or any of their officers, directors, agents, stockholders, members, partners, affiliates and subsidiaries (other than us and our subsidiaries) and that may be a business opportunity for our former sponsors, even if the opportunity is one that we might reasonably have pursued or had the ability or desire to pursue if granted the opportunity to do so. No such person will be liable to us for breach of any fiduciary or other duty, as a director or officer or otherwise, by reason of the fact that such person, acting in good faith, pursues or acquires any such business opportunity, directs any such business opportunity to another person or fails to present any such business opportunity, or information regarding any such business opportunity, to us unless, in the case of any such person who is our director or officer, any such business opportunity is expressly offered to such director or officer solely in his or her capacity as our director or officer. Neither our former sponsors nor any of their representatives has any duty to refrain from engaging directly or indirectly in the same or similar business activities or lines of business as us or any of our subsidiaries.

Exclusive Jurisdiction of Certain Actions

Our amended and restated certificate of incorporation requires, to the fullest extent permitted by law, that derivative actions brought in our name, actions against directors, officers and employees for breach of fiduciary duty and other similar actions may be brought only in the Court of Chancery in the State of Delaware. Although we believe this provision benefits us by providing increased consistency in the application of Delaware law in the types of lawsuits to which it applies, the provision may have the effect of discouraging lawsuits against our directors and officers. The enforceability of similar exclusive jurisdiction provisions in other companies’ certificates of incorporation has been challenged in legal proceedings, and it is possible that, in connection with any action, a court could find the exclusive jurisdiction provision contained in our amended and restated certificate of incorporation to be inapplicable or unenforceable in such action.

Transfer Agent and Registrar

The transfer agent and registrar for our common stock is Computershare Trust Company, N.A. Its address is 250 Royall Street, Canton, Massachusetts 02021.

Listing

Our shares of common stock are listed on the Nasdaq Global Select Market under the trading symbol “CDW.”

DESCRIPTION OF DEPOSITARY SHARES

The following description of the depositary shares and the terms of the deposit agreement is a summary. It summarizes only those aspects of the depositary shares and those portions of the deposit agreement that we believe will be most important to your decision to invest in our depositary shares. There may be other provisions in the deposit agreement that are also important to you. You should read the deposit agreement for a full description of the terms of the depositary shares. The form of the deposit agreement will be filed or incorporated by reference as an exhibit to the registration statement of which this prospectus is a part.

The particular terms of the depositary shares offered by any prospectus supplement and the extent to which the general provisions described below may apply to such depositary shares will be outlined in the applicable prospectus supplement.

General

We may elect to offer fractional interests in preferred shares, rather than offer whole preferred shares. If we choose to do this, we will provide for the issuance by a depositary to the public of receipts for depositary shares. Each depositary share will represent fractional interests of a particular series of preferred shares.

The shares of any series of preferred shares underlying the depositary shares will be deposited under a separate deposit agreement between us and a bank or trust company, which we will select. The bank or trust company must have its principal office in the United States and a combined capital and surplus of at least $50,000,000. The prospectus supplement relating to a series of depositary shares will state the name and address of the depositary. Unless otherwise provided by the deposit agreement, each owner of depositary shares will be entitled, in proportion to the applicable fractional interests in preferred shares underlying the depositary shares, to all the rights and preferences of the preferred stock underlying the depositary shares including dividend, voting, redemption, conversion and liquidation rights.

The depositary shares will be evidenced by depositary receipts issued under the deposit agreement. Depositary receipts will be distributed to those persons purchasing the fractional interests in shares of the related series of preferred shares in accordance with the terms of the offering described in the related prospectus supplement.

Dividends and Other Distributions

The depositary will distribute all cash dividends or other cash distributions received in respect of preferred shares to the record holders of depositary shares relating to the preferred shares in proportion to the numbers of the depositary shares owned by the holders on the relevant record date. The depositary will distribute only an amount, however, that can be distributed without attributing to any holder of depositary shares a fraction of one cent, and any balance not so distributed will be added to and treated as part of the next sum received by the depositary for distribution to record holders of depositary shares.

If there is a non-cash distribution, the depositary will distribute property received by it to the record holders of depositary shares entitled to it, unless the depositary determines that it is not feasible to make the distribution. If this happens, the depositary may, with our approval, sell the property and distribute the net sale proceeds to the holders. The deposit agreement will also contain provisions relating to the manner in which any subscription or similar rights that we offer to holders of the preferred stock will be made available to the holders of depositary shares.

Redemption of Depositary Shares

If a series of the preferred shares underlying the depositary shares is redeemed in whole or in part, the depositary shares will be redeemed from the redemption proceeds received by the depositary. The depositary will mail notice of redemption not less than 30, and not more than 60, days before the date fixed for redemption to the

7

record holders of the depositary shares to be redeemed at their addresses appearing in the depositary’s books. The redemption price for each depositary share will be equal to the applicable fraction of the redemption price for each share payable with respect to the series of the preferred shares. Whenever we redeem preferred shares held by the depositary, the depositary will redeem on the same redemption date the number of depositary shares relating to the preferred shares so redeemed. If less than all of the depositary shares are to be redeemed, the depositary shares to be redeemed will be selected by lot or proportionally as may be determined by the depositary.

After the date fixed for redemption, the depositary shares called for redemption will no longer be considered outstanding and all rights of the holders of the depositary shares will cease, except the right to receive the cash, securities or other property payable upon the redemption and any cash, securities or other property to which the holders of the redeemed depositary shares were entitled upon surrender to the depositary of the depositary receipts evidencing the depositary shares.

The amount distributed in any of the foregoing cases will be reduced by any amount required to be withheld by us or the depositary on account of any taxes.

Voting the Preferred Shares

Upon receipt of notice of any meeting at which the holders of the preferred shares are entitled to vote, the depositary will mail the information contained in the notice of meeting to the record holders of the depositary shares relating to the preferred shares. Each record holder of depositary shares on the record date, which will be the same date as the record date for the preferred shares, will be entitled to instruct the depositary how to exercise the voting rights pertaining to the number of preferred shares underlying the holder’s depositary shares. The depositary will endeavor, to the extent practicable, to vote the number of preferred shares underlying the depositary shares in accordance with these instructions, and we will agree to take all action which the depositary may consider necessary in order to enable the depositary to vote the shares. The depositary will abstain from voting preferred shares to the extent it does not receive specific instructions from the holders of depositary shares representing such preferred shares.

Amendment and Termination of Depositary Agreement

We may enter into an agreement with the depositary at any time to amend the form of depositary receipt evidencing the depositary shares and any provision of the deposit agreement. However, the holders of a majority of the depositary shares must approve any amendment which materially and adversely alters the rights of the existing holders of depositary shares. We or the depositary may terminate the deposit agreement only if (a) all outstanding depositary shares issued under the agreement have been redeemed or (b) a final distribution in connection with any liquidation, dissolution or winding up has been made to the holders of the depositary shares.

Charges of Depositary

We will pay all transfer and other taxes and governmental charges arising solely from the existence of the depositary arrangements. We will also pay charges of the depositary in connection with the initial deposit of the preferred shares and any redemption of the preferred shares. Holders of depositary shares will pay transfer and other taxes and governmental charges and such other charges as are expressly provided in the deposit agreement to be for their accounts.

Resignation and Removal of Depositary

The depositary may resign at any time by delivering to us notice of its election to resign, and we may at any time remove the depositary. Any resignation or removal will take effect when a successor depositary has been appointed and has accepted the appointment. Appointment must occur within 60 days after delivery of the notice of resignation or removal. The successor depositary must be a bank or trust company having its principal office in the United States and having a combined capital and surplus of at least $50,000,000.

8

Miscellaneous

The depositary will forward to the holders of depositary shares all reports and communications that we deliver to the depositary and that we are required to furnish to the holders of the preferred shares. Neither the depositary nor we will be liable if it is prevented or delayed by law or any circumstance beyond its control in performing its obligations under the deposit agreement. The obligations of us and the depositary under the deposit agreement will be limited to performance in good faith of their duties under the agreement and they will not be obligated to prosecute or defend any legal proceeding in respect of any depositary shares or preferred shares unless the holders provide them with satisfactory indemnity. They may rely upon written advice of counsel or accountants, or information provided by persons presenting preferred stock for deposit, holders of depositary shares or other persons believed to be competent and on documents they believe to be genuine.

9

DESCRIPTION OF WARRANTS

The following description of the warrants and terms of the warrant agreement is a summary. It summarizes only those aspects of the warrants and those portions of the warrant agreement which we believe will be most important to your decision to invest in our warrants. There may be other provisions in the warrant agreement and the warrant certificate relating to the warrants which are also important to you. You should read these documents for a full description of the terms of the warrants. The forms of the warrant agreement and the warrant certificate will be filed or incorporated by reference as exhibits to the registration statement of which this prospectus is a part.

General

We may issue warrants to purchase debt or equity securities. We may issue warrants independently or together with any offered securities. The warrants may be attached to or separate from those offered securities. We will issue the warrants under warrant agreements to be entered into between us and a bank or trust company, as warrant agent, all as described in the applicable prospectus supplement. The warrant agent will act solely as our agent in connection with the warrants and will not assume any obligation or relationship of agency or trust for or with any holders or beneficial owners of warrants.

The prospectus supplement relating to any warrants that we may offer will contain the specific terms of the warrants. These terms may include, but are not limited to, the following:

10

Exercise of Warrants

Each warrant will entitle the holder of warrants to purchase for cash the amount of debt or equity securities, at the exercise price stated or determinable in the prospectus supplement for the warrants. Warrants may be exercised at any time up to the close of business on the expiration date shown in the prospectus supplement relating to the warrants, unless otherwise specified in the applicable prospectus supplement. After the close of business on the expiration date, unexercised warrants will become void. Warrants may be exercised as described in the prospectus supplement relating to the warrants. When the warrant holder makes the payment and properly completes and signs the warrant certificate at the corporate trust office of the warrant agent or any other office indicated in the prospectus supplement, we will, as soon as possible, forward the debt or equity securities that the warrant holder has purchased. If the warrant holder exercises the warrant for less than all of the warrants represented by the warrant certificate, we will issue a new warrant certificate for the remaining warrants.

11

DESCRIPTION OF SUBSCRIPTION RIGHTS

This section describes the general terms of the subscription rights to purchase common stock or other securities that we may offer to stockholders using this prospectus. The following description is only a summary and does not purport to be complete. You must look at the applicable forms of subscription agent agreement and subscription certificate for a full understanding of all terms of any series of subscription rights. The forms of the subscription agent agreement and the subscription certificate will be filed or incorporated by reference as exhibits to the registration statement of which this prospectus is a part.

General

Subscription rights may be issued independently or together with any other security and may or may not be transferable. As part of the rights offering, we may enter into a standby underwriting or other arrangement under which the underwriters or any other person would purchase any securities that are not purchased in such rights offering. If we issue subscription rights, they may be governed by a separate subscription agent agreement that we will sign with a bank or trust company, as rights agent, that will be named in the applicable prospectus supplement. The rights agent will act solely as our agent and will not assume any obligation to any holders of rights certificates or beneficial owners of rights.

In general, a right entitles the holder to purchase for cash a specific number of shares of common stock or other securities at a specified exercise price. The rights are normally issued to stockholders as of a specific record date, may be exercised only for a limited period of time and become void following the expiration of such period. If we determine to issue subscription rights, we will accompany this prospectus with a prospectus supplement that will describe, among other things:

12

If fewer than all of the rights issued in any rights offering are exercised, we may offer any unsubscribed securities directly to persons other than stockholders, to or through agents, underwriters or dealers or through a combination of such methods, including pursuant to standby arrangements, as described in the applicable prospectus supplement.

13

DESCRIPTION OF DEBT SECURITIES AND GUARANTEES

The following description discusses the general terms and provisions of the debt securities that we may offer under this prospectus. The debt securities may be issued as senior debt securities or subordinated debt securities. The indebtedness represented by the senior debt securities will rank equally with all of our other unsecured and unsubordinated debt. The senior debt securities will, however, be subordinated in right of payment to all of our secured indebtedness to the extent of the value of the assets securing that indebtedness. The indebtedness represented by the subordinated debt securities will rank junior and be subordinate in right of payment to the prior payment in full of our senior debt, to the extent and in the manner set forth in the applicable prospectus supplement for the securities.

Unless otherwise specified in the applicable prospectus supplement, the senior debt securities and the subordinated debt securities will be issued by CDW LLC and CDW Finance Corporation and will be guaranteed by CDW Corporation and/or one or more of our U.S. subsidiaries. The senior debt securities and the subordinated debt securities will be issued under indenture(s) between us and one or more United States banking institutions. Unless otherwise specified in the applicable prospectus supplement, the trustee under the indentures will be U.S. Bank National Association.

The form of the indenture is filed as an exhibit to the registration statement of which this prospectus is a part. The indenture is subject to and governed by the Trust Indenture Act of 1939, as amended, or the Trust Indenture Act, and may be supplemented or amended from time to time following its execution. The form of the indenture gives us broad authority to set the particular terms of each series of debt securities, including the right to modify certain of the terms contained in the indenture. The particular terms of a series of debt securities and the extent, if any, to which the particular terms of the issue modify the terms of the form of indenture will be described in the prospectus supplement relating to such series of debt securities.

CDW LLC and CDW Finance Corporation may also issue additional senior debt securities under the indenture governing their 5.0% Senior Notes due 2023 (the “2023 Senior Notes”), the indenture governing their 5.5% Senior Notes due 2024 (the “2024 Senior Notes”) or the indenture governing their 5.0% Senior Notes due 2025 (the “2025 Senior Notes’), which will have terms substantially identical in all material respects to the 2023 Senior Notes, 2024 Senior Notes or the 2025 Senior Notes, respectively, and which will be guaranteed by CDW Corporation and our domestic subsidiaries that are guarantors under our senior secured term loan facility. The 2023 Senior Notes and any additional notes issued under the indenture governing the 2023 Senior Notes will be treated as a single class for all purposes under the indenture governing the 2023 Senior Notes. The 2024 Senior Notes and any additional notes issued under the indenture governing the 2024 Senior Notes will be treated as a single class for all purposes under the indenture governing the 2024 Senior Notes. The 2025 Senior Notes and any additional notes issued under the indenture governing the 2025 Senior Notes will be treated as a single class for all purposes under the indenture governing the 2025 Senior Notes. The indentures governing the 2023 Senior Notes, 2024 Senior Notes and the 2025 Senior Notes are filed as exhibits to the registration statement of which this prospectus is a part.

The following summary describes selected provisions of the form of indenture. This summary does not describe every aspect of the debt securities or the indenture and is subject to, and qualified in its entirety by reference to, all the provisions of the indenture, including the terms defined in the indenture. We urge you to read the indenture in its entirety. This summary is also subject to, and qualified in its entirety by reference to, the description of the particular debt securities in the applicable prospectus supplement.

General

The indenture provides that we will be able to issue an unlimited aggregate principal amount of debt securities under the indentures, in one or more series, and in any currency or currency units. We are not required to issue all debt securities of one series at the same time and, unless otherwise provided, we may reopen a series, without the consent of the holders of the debt securities of that series, for issuances of additional debt securities of that series.

14

Prior to the issuance of each series of debt securities, the terms of the particular securities will be specified in a supplemental indenture or a resolution of our board of directors or in one or more officers’ certificates pursuant to a board resolution. We will describe in the applicable prospectus supplement the terms of the debt securities being offered, including:

The general provisions of the indentures do not contain any provisions that would limit our ability or the ability of our subsidiaries to incur indebtedness or that would afford holders of our debt securities protection in the event of a highly leveraged or similar transaction involving us or any of our subsidiaries. Please refer to the applicable prospectus supplement for information with respect to any deletions from, modifications of or additions to, the events of default described below that are applicable to the offered debt securities or any covenants or other provisions providing event risk or similar protection.

Payment

Unless we state otherwise in the applicable prospectus supplement, we will pay interest on a debt security on each interest payment date to the person in whose name the debt security is registered as of the close of business on the regular record date relating to the interest payment date.

15

Unless we state otherwise in the applicable prospectus supplement, we will pay principal of and any premium on the debt securities at stated maturity, upon redemption or otherwise, upon presentation of the debt securities at the office of the trustee, as our paying agent, or at other designated places. Any other paying agent initially designated for the debt securities of a particular series will be identified in the applicable prospectus supplement.

Forms, Transfers and Exchanges

The debt securities of each series will be issued only in fully registered form, without interest coupons. Unless we state otherwise in the applicable prospectus supplement, the debt securities will be issued in denominations of $2,000 each and integral multiples of $1,000 in excess of $2,000.

Subject to the terms of the indenture and the limitations applicable to global securities, you may exchange or transfer debt securities at the corporate trust office of the trustee or at any other office or agency maintained by us for that purpose, without the payment of any service charge, except for any tax or governmental charge.

Global Securities

The debt securities of any series may be issued, in whole or in part, by one or more global certificates that will be deposited with the depositary identified in the applicable prospectus supplement.

No global security may be exchanged in whole or in part for the debt securities registered in the name of any person other than the depositary for that global security or any nominee of that depositary except in the following circumstances or as otherwise provided in the applicable prospectus supplement. The depositary may discontinue providing its services as depositary with respect to the securities at any time by giving reasonable notice to us. Under such circumstances, in the event that a successor depositary is not obtained, certificates are required to be printed and delivered. In addition, we may decide to discontinue use of the system of book-entry-only transfers through a depositary. In that event, certificates will be printed and delivered to the depositary.

Unless otherwise stated in any prospectus supplement, The Depository Trust Company (“DTC”) will act as depositary. Beneficial interests in global certificates will be shown on, and transfers of global certificates will be effected only through records maintained by DTC and its participants.

Events of Default

Unless otherwise specified in the applicable prospectus supplement, an event of default occurs with respect to debt securities of any series if:

16

If an event of default (other than an event of default with respect to certain events of bankruptcy affecting us) shall occur and be continuing, the trustee acting at the written direction of the holders of at least 25% in aggregate principal amount of the then total outstanding debt securities of an affected series may declare the principal of the debt securities and any accrued interest on the debt securities to be due and payable by notice in writing to us and the trustee specifying the respective event of default and that it is a “notice of acceleration,” and the same shall become immediately due and payable.

Upon such declaration of acceleration, the aggregate principal amount of, and accrued and unpaid interest, if any, on all of the outstanding debt securities shall ipso facto become and be immediately due and payable in cash without any declaration or other act on the part of the trustee or any holder of the debt securities. After such acceleration, but before a judgment or decree based on acceleration, the holders of a majority in aggregate principal amount of such outstanding debt securities may, under certain circumstances, rescind and annul such acceleration if all events of default, other than the nonpayment of accelerated principal of or interest on such debt securities, have been cured or waived as provided in the indenture.

The holders of a majority in principal amount of the debt securities then outstanding may rescind and cancel such declaration and its consequences:

No such rescission shall affect any subsequent default or impair any right consequent thereto.

The holders of a majority in principal amount of the debt securities of the affected series issued and then outstanding under the indenture may waive any existing default or event of default under the indenture, and its consequences, except a default in the payment of the principal of or interest on such debt securities.

Holders of the debt securities may not enforce the indenture or such debt securities except as provided in such indenture and under the Trust Indenture Act. Subject to the provisions of the indenture relating to the duties of the trustee, the trustee is under no obligation to exercise any of its rights or powers under the indenture at the request, order or direction of any of the holders of the debt securities, unless such holders have offered to the trustee reasonable indemnity satisfactory to the trustee. Subject to all provisions of the indenture and applicable law, the holders of a majority in aggregate principal amount of the then outstanding debt securities of a series issued under the Indenture have the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee or exercising any trust or power conferred on the trustee.

We are required to deliver to the trustee annually a statement regarding compliance with the indenture. Upon becoming aware of any default or event of default, we are required to promptly deliver to the trustee a statement specifying such default or event of default (unless such default or event of default has been cured prior to such time).

17

Merger or Consolidation

The indenture provides that we may not consolidate or merge with or into another person, whether or not we are the surviving entity, and that we may not sell, assign, transfer, convey, lease or otherwise dispose of all or substantially all of our properties and assets, unless:

Modification or Waiver

Without the consent of any holder, we and the trustee may modify the indenture for any of the following purposes:

18

We and the trustee may, with some exceptions, amend or modify either indenture with the consent of the holders of at least a majority in aggregate principal amount of the outstanding debt securities of all series affected by the amendment or modification. However, no amendment or modification may, without the consent of the holder of each outstanding debt security affected thereby:

Legal Defeasance and Covenant Defeasance

The indenture provides that we may, at our option and at any time, elect to have all of our obligations and the obligations of the applicable guarantors discharged with respect to any outstanding debt securities issued under the indenture, subject to the terms and conditions as specified in the applicable prospectus supplement, except for:

In addition, we may, at our option and at any time, elect to have our obligations and the obligations of the guarantors released with respect to certain covenants that are described in the indenture and thereafter any omission to comply with those covenants will not constitute a default or event of default with respect to the debt securities issued thereunder. In the event that a covenant defeasance occurs, certain events (not including

19

nonpayment, bankruptcy, receivership, rehabilitation and insolvency events of ours) described under “—Events of Default” will no longer constitute an event of defaults with respect the debt securities issued under the indenture.

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

Senior Debt Securities

The senior debt securities will be unsecured senior obligations and will rank equally with all other senior unsecured and unsubordinated debt. The senior debt securities will, however, be subordinated in right of payment to all of our secured indebtedness to the extent of the value of the assets securing that indebtedness. Except as

20

provided in the senior indenture or specified in any authorizing resolution or supplemental indenture relating to a series of senior debt securities to be issued, no senior indenture will limit the amount of additional indebtedness that may rank equally with the senior debt securities or the amount of indebtedness, secured or otherwise, that may be incurred or preferred shares that may be issued by any of our subsidiaries.

Subordinated Debt

Subordinated debt securities will be subordinate and junior in right of payment, to the extent and in the manner set forth in the indenture, to all of our “senior indebtedness.” The indenture defines “senior indebtedness” as all obligations or indebtedness of, or guaranteed or assumed by, us for borrowed money whether or not represented by bonds, notes, debentures or other similar instruments, and amendments, renewals, extensions, modifications and refundings of any such indebtedness or obligation, in each case, whether outstanding on the date hereof or the date the debt securities are issued or created, incurred, or thereafter guaranteed or assumed. “Senior indebtedness” does not include any subordinated debt securities or any other obligations specifically designated as being subordinate in right of payment to senior indebtedness.

In general, the holders of all senior indebtedness are first entitled to receive payment of the full amount unpaid on senior indebtedness before the holders of any of the subordinated debt securities are entitled to receive a payment on account of the principal or interest on the indebtedness evidenced by the subordinated debt securities in certain events. Because the subordinated debt securities will be our unsecured obligations, our secured debt and other secured obligations will also be effectively senior to the subordinated debt securities to the extent of the value of the assets securing such debt or other obligations.

Corporate Existence

Subject to the terms of the indenture, we will do or cause to be done all things necessary to preserve and keep in full force and effect our corporate (and in the case of CDW LLC, limited liability company) existence, charter and statutory rights and franchises; provided, however, that we will not be required to preserve any right or franchise if we determine that the preservation thereof is no longer desirable in the conduct of our business.

Governing Law

The indentures and our debt securities will be governed by, and construed in accordance with, the law of the State of New York.

Guarantees

If the applicable prospectus supplement relating to a series of debt securities provides that those debt securities will have the benefit of a guarantee by CDW Corporation and/or any of its then existing or future domestic subsidiaries, then the debt securities will be fully and unconditionally guaranteed by such guarantors. Unless otherwise specified in the applicable prospectus supplement, we expect that the debt securities will be guaranteed by the guarantors under our existing indentures and our existing senior credit facilities. The guarantees will be general obligations of each guarantor. The guarantees will be joint and several obligations of the guarantors. If a series of debt securities is so guaranteed, the indenture or a supplemental indenture to the base indenture will be executed by each guarantor. The obligations of each guarantor under its guarantee will be limited as necessary to prevent that guarantee from constituting a fraudulent conveyance under applicable law. The terms of any guarantee and the conditions upon which any guarantor may be released from its obligations under that guarantee will be set forth in the applicable prospectus supplement.

21

DESCRIPTION OF SHARE PURCHASE CONTRACTS AND SHARE PURCHASE UNITS

We may issue share purchase contracts, including contracts obligating holders to purchase from us, and us to sell to the holders, a specified number of shares of common stock at a future date or dates. The price per share of common stock and the number of shares of common stock may be fixed at the time the share purchase contracts are issued or may be determined by reference to a specific formula stated in the share purchase contracts.

The share purchase contracts may be issued separately or as part of units that we call “share purchase units.” Share purchase units consist of a share purchase contract and either our debt securities or debt obligations of third parties, including United States treasury securities, securing the holders’ obligations to purchase the common stock under the share purchase contracts.

The share purchase contracts may require us to make periodic payments to the holders of the share purchase units or vice versa, and these payments may be unsecured or refunded on some basis. The share purchase contracts may require holders to secure their obligations in a specified manner.

The applicable prospectus supplement will describe the terms of the share purchase contracts or share purchase units. The description in the prospectus supplement will only be a summary, and you should read the share purchase contracts, and, if applicable, collateral or depositary arrangements, relating to the share purchase contracts or share purchase units. Material United States federal income tax considerations applicable to the share purchase units and the share purchase contracts will also be discussed in the applicable prospectus supplement.

Each share purchase contract or share purchase unit and any related agreement will be governed by, and construed in accordance with, the laws of the State of New York.

22

SELLING STOCKHOLDERS

Selling stockholders are persons or entities that, directly or indirectly, have acquired or will from time to time acquire from us, shares of common stock in various private transactions. Such selling stockholders may be parties to registration rights agreements with us, or we otherwise may have agreed or will agree to register their securities for resale. The initial purchasers of our securities, as well as their transferees, pledges, donees or successors, all of whom we refer to as “selling stockholders,” may from time to time offer and sell the securities pursuant to this prospectus and any applicable prospectus supplement.

The applicable prospectus supplement will set forth the name of each of the selling stockholders and the number of shares of our common stock beneficially owned by such selling stockholders that are covered by such prospectus supplement. The applicable prospectus supplement will also disclose whether any of the selling stockholders has held any position or office with, has been employed by or otherwise has had a material relationship with us during the three years prior to the date of the prospectus supplement.

PLAN OF DISTRIBUTION

We may offer and sell the securities described in this prospectus, and certain stockholders may sell common stock, in one or more of the following ways from time to time in one or more transactions:

The prospectus supplement with respect to each series of securities will state the terms of the offering of the securities, including:

If we or any selling stockholders use underwriters or dealers in the sale, the securities will be acquired by the underwriters or dealers for their own account and may be resold from time to time in one or more transactions, including:

23

Any initial public offering price and any discounts or concessions allowed or reallowed or paid to dealers may be changed from time to time.

If underwriters are used in the sale of any securities, the securities may be offered either to the public through underwriting syndicates represented by managing underwriters, or directly by underwriters. Generally, the underwriters’ obligations to purchase the securities will be subject to certain conditions precedent. The underwriters will be obligated to purchase all of the securities if they purchase any of the securities.

We may enter into derivative transactions with third parties, or sell securities not covered by this prospectus to third parties in privately negotiated transactions. If the applicable prospectus supplement indicates, in connection with those derivatives, the third parties may sell securities covered by this prospectus and the applicable prospectus supplement, including short sale transactions. If so, the third party may use securities pledged by us or borrowed from us or others to settle those sales or to close out any related open borrowings of stock, and may use securities received from us in settlement of those derivatives to close out any related open borrowings of stock. The third party in such sale transactions will be an underwriter and will be identified in the applicable prospectus supplement or a post-effective amendment to this registration statement.

If indicated in an applicable prospectus supplement, we and any selling stockholders may sell the securities through agents from time to time. The applicable prospectus supplement will name any agent involved in the offer or sale of the securities and any commissions paid to them. Generally, any agent will be acting on a best efforts basis for the period of its appointment. We and any selling stockholders may authorize underwriters, dealers or agents to solicit offers by certain purchasers to purchase the securities from us and any selling stockholders at the public offering price set forth in the applicable prospectus supplement pursuant to delayed delivery contracts providing for payment and delivery on a specified date in the future. The delayed delivery contracts will be subject only to those conditions set forth in the applicable prospectus supplement, and the applicable prospectus supplement will set forth any commissions paid for solicitation of these delayed delivery contracts.

Offered securities may also be offered and sold, if so indicated in the applicable prospectus supplement, in connection with a remarketing upon their purchase, in accordance with a redemption or repayment pursuant to their terms, or otherwise, by one or more remarketing firms, acting as principals for their own accounts or as agents for us or any selling stockholders. Any remarketing firm will be identified and the terms of its agreements, if any, with us or any selling stockholders and its compensation will be described in the applicable prospectus supplement.

Agents, underwriters and other third parties described above may be entitled to indemnification by us or any selling stockholders against certain civil liabilities under the Securities Act, or to contribution with respect to payments which the agents or underwriters may be required to make in respect thereof. Agents, underwriters and such other third parties may be customers of, engage in transactions with, or perform services for us in the ordinary course of business.

Each series of securities will be a new issue of securities and may not have an established trading market, other than our common stock, which is listed on the Nasdaq Global Select Market. The securities other than the common stock may or may not be listed on a national securities exchange and no assurance can be given that there will be a secondary market for any such securities or liquidity in the secondary market if one develops. Any underwriters to whom securities are sold by us or any selling stockholders for public offering and sale may make a market in the securities, but such underwriters will not be obligated to do so and may discontinue any market making at any time without notice.

Fees and Commissions

In compliance with the guidelines of the Financial Industry Regulatory Authority (“FINRA”), the aggregate maximum discount, commission or agency fees or other items constituting underwriting compensation to be

24

received by any FINRA member or independent broker-dealer will not exceed 8% of any offering pursuant to this prospectus and any applicable prospectus supplement or pricing supplement, as the case may be; however, it is anticipated that the maximum commission or discount to be received in any particular offering of securities will be significantly less than this amount.

LEGAL MATTERS

Certain legal matters with regard to the validity of the securities will be passed upon for us by Kirkland & Ellis LLP, Chicago, Illinois. Certain matters under Wisconsin law will be passed upon by Foley & Lardner LLP. Any underwriters or agents will be advised about other issues relating to any offering by counsel named in the applicable prospectus supplement.
