UNDERWRITING (CONFLICT OF INTEREST)

The selling stockholders identified in this prospectus supplement are offering the shares of common stock described in this prospectus supplement and the accompanying prospectus through a number of underwriters. J.P. Morgan Securities, LLC, Evercore Group L.L.C. and Citigroup Global Markets Inc. are acting as representatives of the underwriters. We, Ziff Davis and the selling stockholders have entered into an underwriting agreement with the underwriters.

Subject to the terms and conditions of the underwriting agreement, the selling stockholders have agreed to sell to the underwriters for cash, and each underwriter has severally agreed to purchase, at the public offering price less the underwriting discounts and commissions set forth on the cover page of this prospectus supplement, the number of shares of common stock listed next to its name in the following table:

The underwriting agreement provides that if an underwriter defaults, the non-defaulting underwriters may in their discretion arrange for the representatives or other parties to purchase such shares on the terms contained in the underwriting agreement. If the non-defaulting underwriters do not arrange for the purchase of such shares with thirty-six hours of the default, we and the selling stockholders will have an additional thirty-six hours to arrange for another party or parties satisfactory to the non-defaulting underwriters to purchase such shares. The underwriters are committed to purchase all of the shares of common stock offered by the selling stockholders if, after giving effect to any such arrangements for the purchase of the shares of a defaulting underwriter by the non-defaulting underwriters, the aggregate number of such shares which remains unpurchased does not exceed one-eleventh of the aggregate number of all the shares to be purchased.

The underwriters propose to offer the common stock directly to the public initially at the public offering price set forth on the cover page of this prospectus supplement and to certain dealers at that price less a concession not in excess of $0.369 per share. After the initial offering of the shares to the public, if all of the shares of common stock are not sold at the initial public offering price, the underwriters may change the offering price and other selling terms. Sales of shares made outside of the United States may be made by affiliates of the underwriters.

The underwriters have an option to buy up to 300,000 additional shares of common stock from the selling securityholders. The underwriters have 30 days from the date of this prospectus to exercise this option to purchase additional shares. If any shares are purchased with this option to purchase additional shares, the underwriters will purchase shares in approximately the same proportion as shown in the table above. If any additional shares of common stock are purchased, the underwriters will offer the additional shares on the same terms as those on which the shares are being offered.

The underwriting discounts and commissions are equal to the public offering price per share of common stock less the amount paid by the underwriters to the selling stockholders per share of common stock. The underwriting discounts and commissions are $1.845 per share. The following table shows the per share and total underwriting discounts and commissions to be paid to the underwriters assuming both no exercise and full exercise of the underwriters’ option to purchase additional shares.

The pricing with respect to the debt-for-equity exchange will (i) be negotiated at arm’s length, (ii) involve a fixed dollar amount and (iii) not contain any variable component. See “—The Debt-for-Equity Exchange.”

We will bear certain of the costs associated with this offering in accordance with the stockholder and registration rights agreement between us and Ziff Davis and the underwriting agreement. We estimate that our total expenses of this offering, including registration, filing and listing fees, printing fees and legal and accounting expenses will be approximately $482,909. The selling stockholders will bear the underwriting discounts and commissions and transfer taxes relating to this offering. We have agreed to reimburse the underwriters for the FINRA-related fees and expenses of the underwriters’ legal counsel in an amount up to $50,000.00.

This prospectus supplement and accompanying prospectus in electronic format may be made available on the web sites maintained by one or more underwriters, or selling group members, if any, participating in the offering. The underwriters may agree to allocate a number of shares to underwriters and selling group members for sale to their online brokerage account holders. Internet distributions will be allocated by the representatives to underwriters and selling group members that may make Internet distributions on the same basis as other allocations.

We have agreed that we will not (1) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, or submit to, or file with, the SEC a registration statement under the Securities Act of 1933 (the “Securities Act”) relating to, any shares of shares of common stock or any securities convertible into or exercisable or exchangeable for shares of common stock, or publicly disclose the intention to undertake any of the foregoing, or (2) enter into any swap or other agreement that transfers, in whole or in part, any of the economic consequences of ownership of the Stock or any such other securities, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of shares of common stock or such other securities, in cash or otherwise, in each case without the prior written consent of the representatives of the underwriters for a period of 60 days after the date of this prospectus supplement, other than the shares of common stock offered hereby.

The restrictions described above do not apply to (i) the issuance of shares of common stock or securities convertible into or exercisable for shares of common stock pursuant to the conversion or exchange of convertible or exchangeable securities or the exercise of warrants or options (including net exercise) or the settlement of restricted stock units (“RSUs”) (including net settlement), in each case outstanding on the date of the underwriting agreement and described herein; (ii) grants of stock options, stock awards, restricted stock, RSUs, or other equity awards and the issuance of shares of common stock or securities convertible into or exercisable or exchangeable for shares of Stock (whether upon the exercise of stock options or otherwise) to the Company’s employees, officers, directors, advisors, or consultants pursuant to the terms of an equity compensation plan in effect as of the settlement date of this offering and described herein, provided that such recipients enter into a lock-up agreement with the underwriters; (iii) the filing of any registration statement on Form S-8 relating to securities granted or to be granted pursuant to any plan in effect on the date of the underwriting agreement and described herein or any assumed benefit plan pursuant to an acquisition or similar strategic transaction; or (iv) the issuance of up to 5% of the outstanding shares of common stock or any securities convertible into or exercisable or exchangeable for shares of common stock issued in connection with future business combinations, acquisitions, joint ventures, commercial relationships or other strategic transactions, provided that such recipients

Morgan Securities LLC on behalf of the underwriters, in each case, subject to certain conditions.

We and Ziff Davis have agreed to indemnify the underwriters against certain liabilities and have agreed to provide contribution with respect to certain payments the underwriters may be required to make in respect thereof, including liabilities under the Securities Act.

Our common stock is listed on Nasdaq under the symbol “CCSI.”

In connection with this offering, the underwriters may engage in stabilizing transactions, which involves making bids for, purchasing and selling shares of common stock in the open market for the purpose of preventing or retarding a decline in the market price of the common stock while this offering is in progress. These stabilizing transactions may include making short sales of the common stock, which involves the sale by the underwriters of a greater number of shares of common stock than they are required to purchase in this offering, and purchasing shares of common stock on the open market to cover positions created by short sales. Short sales may be “covered” shorts, which are short positions in an amount not greater than the underwriters’ option to purchase additional shares referred to above, or may be “naked” shorts, which are short positions in excess of that amount. The underwriters may close out any covered short position either by exercising their option to purchase additional shares, in whole or in part, or by purchasing shares in the open market. In making this determination, the underwriters will consider, among other things, the price of shares available for purchase in the open market compared to the price at which the underwriters may purchase shares through the option to purchase additional shares. A naked short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of the common stock in the open market that could adversely affect investors who purchase in this offering. To the extent that the underwriters create a naked short position, they will purchase shares in the open market to cover the position.

The underwriters have advised us that, pursuant to Regulation M of the Securities Act, they may also engage in other activities that stabilize, maintain or otherwise affect the price of the common stock, including the imposition of penalty bids. This means that if the representatives of the underwriters purchase common stock in the open market in stabilizing transactions or to cover short sales, the representatives can require the underwriters that sold those shares as part of this offering to repay the underwriting discount received by them.

These activities may have the effect of raising or maintaining the market price of the common stock or preventing or retarding a decline in the market price of the common stock, and, as a result, the price of the common stock may be higher than the price that otherwise might exist in the open market. If the underwriters commence these activities, they may discontinue them at any time. The underwriters may carry out these transactions on the Nasdaq, in the over-the-counter market or otherwise.

The offering of the shares by the underwriters is subject to receipt and acceptance and subject to the underwriters’ right to reject any order in whole or in part.

Conflicts of Interest and Relationships

Because each of the debt-for-equity exchange parties will receive 5% or more of the net proceeds of this offering as the selling stockholder, each of the debt-for-equity exchange parties is deemed to have a “conflict of interest” within the meaning of FINRA Rule 5121. Accordingly, this offering will be conducted in compliance with the

S-14

requirements of Rule 5121. The appointment of a “qualified independent underwriter” is not required in connection with this offering as a “bona fide public market,” as defined in Rule 5121, exists for our common stock. In accordance with Rule 5121, neither J.P. Morgan nor Citigroup will confirm any sales to any account over which it exercises discretionary authority without the specific written approval of the transaction from the account holder. See “Use of Proceeds.”

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 affiliates have provided in the past to us, Ziff Davis and our and their respective affiliates, and may provide from time to time in the future, certain commercial banking, financial advisory, investment banking and other services for us, Ziff Davis and such affiliates in the ordinary course of their business, for which they have received and may continue to receive customary fees and commissions. In addition, from time to time and in the ordinary course of their various business activities, the underwriters and their respective affiliates may effect transactions for their own account or the account of customers, and hold on behalf of themselves or their customers, long or short positions in our and/or Ziff Davis’s debt or equity securities or loans (or related derivate securities), and may do so in the future.

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.

The Debt-for-Equity Exchange

Ziff Davis and the debt-for-equity exchange parties expect to enter into a debt-for-equity exchange agreement following the date of this prospectus supplement. Under the debt-for-equity exchange agreement, Ziff Davis expects to exchange the shares of common stock to be sold in this offering for certain existing indebtedness of Ziff Davis held by the debt-for-equity exchange parties. The debt-for-equity exchange parties will then sell such shares of our common stock to the underwriters for cash and the underwriters, including J.P. Morgan and Citigroup, will sell the shares of our common stock in this offering to the public.

The indebtedness of Ziff Davis that is held by the debt-for-equity exchange parties and available for the debt-for-equity exchange consists of certain term loans of Ziff Davis in the aggregate principal amount of $         million. The amount of indebtedness of Ziff Davis held by the debt-for-equity exchange parties is expected to be sufficient to acquire from Ziff Davis all of the shares of common stock to be sold in this offering. The pricing with respect to the debt-for-equity exchange will (i) be negotiated at arm’s length, (ii) involve a fixed dollar amount and (iii) not contain any variable component. Each debt-for-equity exchange party will acquire and sell the shares as principal for its own account, rather than on Ziff Davis’s behalf. Under the debt-for-equity exchange agreement described above, each debt-for-equity exchange party will become the owner of our shares of common stock that such debt-for-equity exchange party acquires in the debt-for-equity exchange prior to the settlement date of this offering and the Ziff Davis indebtedness exchanged in such debt-for-equity exchange will be retired. The debt-for-equity exchange parties, and neither we nor Ziff Davis, will receive the net proceeds from the sale of the shares in this offering. We do not guarantee or have any other obligations in respect of the Ziff Davis indebtedness.

Under U.S. federal securities laws, the debt-for-equity exchange parties will be deemed to be underwriters with respect to any shares of common stock that they acquire in the debt-for-equity exchange and sells in this offering. Ziff Davis may be deemed to be a selling stockholder solely for U.S. federal securities law purposes with respect to any shares of common stock that the debt-for-equity exchange parties acquires from Ziff Davis in the debt-for-equity exchange and sells in this offering.
