Item 4. Purpose of Transaction.

On February 18, 2015, the Issuer and Traxis Group B.V. (“Seller”) entered into a Subscription Agreement (“Subscription Agreement”) with CSB, CCP, CCP2 and the Separate Account (collectively, the “Coliseum Entities”) CCP, CCP2 and the Separate Account have 67.5%, 12.4% and 20.1% membership interests, respectively, in CSB. Pursuant to the Subscription Agreement, CCP, CCP2 and the Separate Account purchased 2,500,000 Common Shares at a purchase price of $10 per share and CSB purchased 100,000 Series A Shares at a purchase price of $100 per share in connection with the Issuer’s acquisition of School Bus Holdings, Inc. from Seller (the “Business Combination”), which closed on February 24, 2015.

Pursuant to the terms of the Subscription Agreement, Gray became a member of the board of directors of the Issuer effective as of the closing of the Business Combination on February 24, 2015. Gray is a Class II director, and his term will expire at the 2016 annual meeting of stockholders.

The foregoing summary of certain provisions of the Subscription Agreement is qualified in its entirety to the Subscription Agreement, a copy of which is filed as Exhibit 2 to this Schedule 13D and incorporated herein by reference.

In connection with the Subscription Agreement, Coliseum entered into a letter agreement with Seller (“Director Removal Letter Agreement”), which provides that Seller will not, and will cause its affiliates to not, vote or provide consent, directly or indirectly, to remove Gray from the Issuer’s board of directors without cause at any time from and after the closing of the Business Combination through the 2016 annual meeting of stockholders. Prior to any sale, transfer or other disposition of any shares of the Common Shares by Seller to an affiliate, such affiliate will agree to be bound by the restrictions of such Director Removal Letter Agreement. The foregoing summary of the Director Removal Letter is qualified in its entirety to the Director Removal Letter, a copy of which is filed as Exhibit 3 to this Schedule 13D and incorporated herein by reference.

On February 24, 2015, the Issuer entered into a registration rights agreement (the “Registration Rights Agreement”) with the Coliseum Entities and certain other investors, pursuant to which the Issuer has agreed to provide the Coliseum Entities with certain “piggyback” registration rights under the Securities Act of 1933, as amended, with respect to their Common Shares, Series A Shares and Common Shares obtainable upon conversion of the Series A Shares. The foregoing summary of certain provisions of the Registration Rights Agreement is qualified in its entirety to the Registration Rights Agreement, a copy of which is filed as Exhibit 4 to this Schedule 13D and incorporated herein by reference.

The Filers acquired the Common Shares and Series A Shares for investment purposes, and such purposes were made in the Filers’ ordinary course of business. In pursuing such investment purposes, the Filers may further purchase, hold, vote, trade, dispose or otherwise deal in the Common Shares or the Series A Shares at times, and in such manner (including pursuant to hedging transactions), as they deem advisable to benefit from changes in market prices of the Common Shares or the Series A Shares, changes in the Issuer’s operations, business strategy or prospects, or from a sale or merger of the Issuer. To evaluate such alternatives, the Filers routinely will monitor the Issuer’s operations, prospects, business development, management, competitive and strategic matters, capital structure, and prevailing market conditions, as well as alternative investment opportunities, liquidity requirements of the Filers and other investment considerations. Consistent with their investment research methods and evaluation criteria, the Filers may discuss such matters with management or directors of the Issuer, other shareholders, industry analysts, existing or potential strategic partners or competitors, investment and financing professionals, sources of credit and other investors. Such factors and discussions may materially affect, and result in, the Filers’ modifying their ownership of the Common Shares and the Series A Shares, exchanging information with the Issuer pursuant to appropriate confidentiality or similar agreements, proposing changes in the Issuer’s operations, governance or capitalization, or in proposing one or more of the other actions described in paragraphs (a) through (j) of Item 4 of Schedule 13D. The Filers reserve the right to formulate other plans and/or make other proposals and take such actions with respect to their investment in the Issuer, including any or all of the actions set forth in paragraphs (a) through (j) of Item 4 of Schedule 13D, or acquire additional Common Shares or Series A Shares or dispose of all Common Shares or Series A Shares beneficially owned by them, in public market or privately negotiated transactions.
