The information set forth in Item 4 hereof is hereby incorporated by reference into this Item 3, as applicable.

Item 4.                  Purpose of Transaction.

On August 15, 2012, Noble purchased 314,399 shares of common stock of JWC Acquisition Corp. (“JWCAC”) in the open market for an aggregate purchase price of $3,143,990.00, which shares were exchanged for shares of Common Stock in connection with the Business Combination (as defined below).

On August 21, 2012, pursuant to the terms of that certain Contribution and Merger Agreement, dated as of June 27, 2012, by and among JWCAC, The Tile Shop, LLC (“TSLLC”), the members of TSLLC, Nabron, the Issuer, Tile Shop Merger Sub, Inc., and Peter J. Jacullo III, in his capacity as Sellers’ Representative (the “Contribution and Merger Agreement”), Nabron contributed its membership interests in ILTS, LLC to the Issuer in exchange for 17,445,432 shares of Common Stock (the “Closing Shares”), a cash payment of $37,732,065.41, and a promissory note in the principal amount of $37,479,695.58 (the “Promissory Note”). The purpose of the transactions contemplated by the Contribution and Merger Agreement was to combine JWCAC and TSLLC as subsidiaries of the Issuer (the “Business Combination”).

Nabron has entered into a lock-up agreement pursuant to which it will not sell any of the Closing Shares until the earlier of (i) one year after the closing date of the Business Combination, (ii) the date on which the last sales price of the Common Stock equals or exceeds $12.00 per share for any 20 trading days within any 30 trading day period commencing at least 150 days after the closing date of the Business Combination and (iii) the date on which the Issuer consummates a liquidation, merger, stock exchange or similar transaction that results in all of the stockholders of the Issuer having the right to exchange their shares of Common Stock for cash, securities or other property. These transfer restrictions do not apply to certain permitted transfers, including transfers to family members, entities established for estate planning purposes, controlled corporations and other entities.

In the event that the Promissory Note and other similar promissory notes of like tenor and term issued in connection with the Business Combination (collectively, the “Notes”) are not repaid by the Issuer in full by the third anniversary of the consummation of the Business Combination, up to an aggregate of $20,000,000 of the then outstanding principal amount of the Notes will be convertible into shares of Common Stock at a conversion price of $10.00 per share.

Pursuant to the terms of that certain Registration Rights Agreement, dated as of June 27, 2012, by and among certain former direct and indirect holders of membership interest in TSLLC (the “Sellers”), the members of JWC Acquisition LLC (the “Sponsor”), and the Issuer (the “Registration Rights Agreement”), the Sellers and the members of the Sponsor hold registration rights with respect to the shares of Common Stock issued or distributed to such parties in connection with the Business Combination. The holders of a majority in interest of the Common Stock held by the Sellers will be entitled to require the Issuer, on up to four occasions, to register under the Securities Act of 1933, as amended (the “Securities Act”) the shares of Common Stock that they received in the Business Combination or may receive upon conversion of the Notes. Demand registration may be made pursuant to the Registration Rights Agreement so long as the estimated market value of the shares of Common Stock to be registered is at least $10,000,000. The holders of a majority in interest of the Common Stock held by the Sellers may elect to exercise these registration rights at any time after the earlier of (i) one year after the closing date of the Business Combination, (ii) the date on which the last sales price of the Common Stock equals or exceeds $12.00 per share for any 20 trading days within any 30 trading day period commencing at least 150 days after the closing date of the Business Combination and (iii) the date on which the Issuer consummates a liquidation, merger, stock exchange or similar transaction that results in all of the stockholders of the Issuer having the right to exchange their shares of Common Stock for cash, securities or other property. In addition, the Sellers and the members of the Sponsor have certain ‘‘piggyback’’ registration rights on registration statements filed by the Issuer following the Business Combination.

On August 21, 2012, in connection with the Business Combination, and pursuant to the terms of that certain Warrant Purchase Agreement, dated as of June 27, 2012, by and among JWC Warrant Holdings, LLC and the other parties thereto (the “Warrant Letter Agreement”), Noble, as assignee of Nabron, purchased warrants to purchase up to 2,390,342 shares of JWCAC common stock for an aggregate purchase price of $1,829,767.51, which became exercisable for an equal number of shares of Common Stock upon the consummation of the Business Combination (the “Warrants”). Pursuant to the terms of that certain Warrant Agreement, dated as of November 17, 2010, by and between JWCAC and Continental Stock Transfer & Trust Company, as warrant agent (the “Warrant Agreement”), the Warrants have an exercise price per underlying share of Common Stock of $11.50 and become exercisable on September 20, 2012.

Subject to applicable legal requirements, one or more of the Reporting Persons may purchase additional securities of the Issuer from time to time in open market or private transactions, depending on their evaluation of the Issuer’s business, prospects and financial condition, the market for the Issuer’s securities, other developments concerning the Issuer, the reaction of the Issuer to the Reporting Persons’ ownership of the Issuer’s securities, other opportunities available to the Reporting Persons, and general economic, money market, and stock market conditions. In addition, depending upon the factors referred to above, the Reporting Persons may dispose of all or a portion of their securities of the Issuer at any time. Each of the Reporting Persons reserves the right to increase or decrease its holdings on such terms and at such times as each may decide. Other than as described above in this Item 4, none of the Reporting Persons have any plan or proposal relating to or that would result in: (a) the acquisition by any person of additional securities of the Issuer or the disposition of securities of the Issuer; (b) an extraordinary corporate transaction, such as a merger, reorganization or liquidation, involving the Issuer or any of its subsidiaries; (c) a sale or transfer of a material amount of assets of the Issuer or any of its subsidiaries; (d) any change in the present board of directors or management of the Issuer, including any plans or proposals to change the number or terms of directors or to fill any existing vacancies on the board of directors of the Issuer; (e) any material change in the present capitalization or dividend policy of the Issuer; (f) any other material change in the Issuer’s business or corporate structure; (g) any changes in the Issuer’s charter, by-laws or instruments corresponding thereto or other actions which may impede the acquisition of control of the Issuer by any person; (h) a class of securities of the Issuer being delisted from a national securities exchange or ceasing to be authorized to be quoted in an inter-dealer quotation system of a registered national securities association; (i) a class of equity securities of the Issuer becoming eligible for termination of registration pursuant to Section 12(g)(4) of the Act; or (j) any action similar to those enumerated above.
