Item 1.01 Entry into a Material Definitive Agreement

On October 15, 2010, Clean Diesel Technologies, Inc. (“Clean Diesel,” “we,” “our,” or “us”), CDTI Merger Sub, Inc., a California corporation and our wholly-owned subsidiary, and Catalytic Solutions, Inc., a California corporation (“CSI”), consummated a business combination pursuant to the terms of the Agreement and Plan of Merger dated May 13, 2010, as amended by letter agreements dated September 1, 2010 and September 14, 2010 (the “Merger Agreement”). Pursuant to the Merger Agreement, CDTI Merger Sub, Inc. merged with and into CSI, and CSI became our wholly-owned subsidiary. We refer to this business combination as the “Merger.” Immediately prior to the Merger, and as contemplated by the Merger Agreement, a one-for-six reverse stock split took effect.

On October 15, 2010, Clean Diesel issued a press release announcing the completion of the Merger and the reverse stock split ratio, among other items. A copy of the press release is attached hereto as Exhibit 99.1.

On October 15, 2010, CSI entered into a Registration Rights Agreement (the “Registration Rights Agreement”) with the investors in its secured convertible notes, which notes are described in more detail in our Registration Statement on Form S-4/A filed with the Securities and Exchange Commission (the “SEC”) on September 23, 2010 (the “Registration Statement”). Subsequent to the Merger, on October 15, 2010, we and CSI entered into an Assignment and Assumption Agreement whereby we agreed to assume CSI’s obligations under the Registration Rights Agreement. The Registration Rights Agreement provides for certain registration rights with respect to the shares of Clean Diesel common stock issued to the holders of such notes in the Merger (which notes converted into shares of CSI’s Class B common stock of CSI immediately prior to the Merger). Pursuant to the Registration Rights Agreement, we agreed to file a registration statement to register the shares of Clean Diesel common stock issued in the Merger to such holders for resale at the request of such holders. In addition, we also granted such holders “piggyback” registration rights. We will pay substantially all of the costs and expenses related to the filing of the registration statements and any underwritten public offering required pursuant to the Registration Rights Agreement.

In addition, on October 15, 2010, prior to the completion of the Merger, pursuant to binding commitment letters from investors in our Regulation S private placement described in our Current Report on Form 8-K filed with the SEC on May 18, 2010 and in the Registration Statement, we sold units consisting of 109,020 shares of our common stock on a post-split basis (654,118 on a pre-split basis) and warrants to purchase 166,666 shares of our common stock on a post-split basis (1,000,000 on a pre-split basis) for approximately $1,000,000 in cash before commissions and expenses. The warrants issued in our Regulation S private placement have an exercise price of $7.92 on a post-split basis ($1.32 on a pre-split basis) and expire on the earlier of (i) October 15, 2013 (the third anniversary of the effective time of the Merger) and (ii) the date that is 30 days after we give notice to the warrant holder that the market value of one share of our common stock has exceeded 130% of the exercise price of the warrant for 10 consecutive days.

Copies of both the Assignment and Assumption Agreement and Registration Rights Agreement are filed as Exhibits to this Current Report on Form 8-K and the foregoing descriptions are qualified in their entirety by the full text of such agreements, which are incorporated by reference herein.

Item 2.01 Completion of Acquisition or Disposition of Assets
 

On October 15, 2010, Clean Diesel’s wholly-owned subsidiary, CDTI Merger Sub, Inc., merged with and into CSI, with CSI continuing as the surviving corporation and as a wholly-owned subsidiary of Clean Diesel.

Pursuant to the terms of the Merger Agreement, each outstanding share of (i) CSI Class A Common Stock was converted into and became exchangeable for 0.007888 fully paid and non-assessable shares of Clean Diesel common stock on a post-split basis (0.04732553 on a pre-split basis) with any fractional shares to be paid in cash and warrants to acquire 0.006454 fully paid and non-assessable shares of Clean Diesel common stock for $7.92 per share on a post-split basis (0.03872267 shares for $1.32 per share on a pre-split basis); and (ii) CSI Class B Common Stock was converted into and became exchangeable for 0.010039 fully paid and non-assessable shares of Clean Diesel common stock on a post-split basis (0.06023308 on a pre-split basis) with any fractional shares to be paid in cash. In connection with the Merger and as contemplated by the Merger Agreement, we also issued 166,666

shares of common stock on a post-split basis (1,000,000 shares on a pre-split basis) and warrants to purchase an additional 166,666 shares of common stock on a post-split basis (1,000,000 shares on a pre-split basis) to Allen & Company LLC, CSI’s financial advisor. The warrants issued in the Merger expire on the earlier of (x) October 15, 2013 (the third anniversary of the effective time of the Merger) and (y) the date that is 30 days after we give notice to the warrant holder that the market value of one share of our common stock has exceeded 130% of the exercise price of the warrant for 10 consecutive days.

As provided in the Merger Agreement, Clean Diesel is issuing (or reserving for issuance pursuant to “in-the-money” warrants) approximately 2,287,943 shares of Clean Diesel common stock on a post-split basis (13,727,658 on a pre-split basis) and warrants to purchase an additional 666,666 shares of Clean Diesel common stock (4,000,000 on a pre-split basis) in connection with the Merger. Based on the closing price of $0.82 per share of Clean Diesel common stock on The NASDAQ Capital Market (“NASDAQ”) on October 15, 2010, the last trading day before the effectiveness of the reverse stock split and the closing of the Merger, the aggregate value of the Clean Diesel common stock issued in connection with the Merger was approximately $11,256,680.

Following the closing of the Merger, CSI became a wholly-owned subsidiary of Clean Diesel and the shares of CSI common stock, which previously traded under the ticker symbols “CTS” and “CTSU” on the AIM market of the London Stock Exchange (the “AIM”), ceased trading on, and were delisted from, the AIM.

Following the consummation of the Merger, the holders of CSI securities (including the holders of its secured convertible notes) and CSI’s financial advisor collectively hold approximately 60% of our outstanding common stock and Clean Diesel stockholders (including investors in its Regulation S offering discussed herein) hold the remaining 40% of our outstanding common stock. For legal purposes, Clean Diesel acquired CSI, although the combination will be accounted for as a reverse merger with CSI deemed to be the “acquiror” for accounting and financial reporting purposes.

The description of the Merger contained in this Item 2.01 does not purport to be complete and is qualified in its entirety by reference to the Merger Agreement as amended by the two letter agreements, which Merger Agreement (as amended) was included as Annex A to the joint proxy statement/information statement and prospectus included in the Registration Statement, and which letter agreements were filed as Exhibits 2.2 and 2.3 to the Registration Statement, all of which are incorporated by reference herein.

On October 15, 2010, we issued a press release announcing the completion of the Merger, among other items. A copy of that press release is included as Exhibit 99.1 hereto.

Item 3.02 Unregistered Sales of Equity Securities

We did not register on the Registration Statement all of the shares and warrants issued on October 15, 2010 in connection with the Merger. Only an aggregate 560,112 shares of common stock on a post-split basis (or 3,360,676 shares on a pre-split basis) and warrants to acquire 458,295 shares of common stock on a post-split basis (or 2,749,770 shares on a pre-split basis) were registered on the Registration Statement. Accordingly, the following securities issued on October 15, 2010 in connection with the Merger have not been registered under the Securities Act of 1933, as amended (the “Act”), or state securities laws, and may not be offered or sold in the United States absent registration with the SEC or an applicable exemption from the registration requirements: (a) an aggregate 1,510,189 shares of our common stock on a post-split basis (9,061,160 on a pre-split basis) to the holders of CSI’s Class B common stock, (b) 166,666 shares of common stock on a post-split basis (1,000,000 shares on a pre-split basis) and warrants to purchase 166,666 shares of common stock on a post-split basis (1,000,000 shares on a pre-split basis) to Allen & Company LLC, CSI’s financial advisor, and (c) an aggregate 50,969 shares of common stock on a post-split basis (305,822 shares of common stock on a pre-split basis) and warrants to acquire 41,705 shares of common stock on a post-split basis (or 250,230 shares on a pre-split basis) to CSI’s former non-employee directors. All of these shares of Clean Diesel common stock and warrants to purchase Clean Diesel common stock were issued in reliance upon the exemption from the registration requirements of the Act pursuant to Section 4(2) of the Act and/or Rule 506 of Regulation D promulgated thereunder. CSI has agreed to use commercially reasonable efforts to register for resale under the Act the shares of Clean Diesel common stock issued or issuable upon exercise of warrants issued to Allen & Company. In addition to the securities issued as part of the Merger consideration, Clean Diesel issued 32,414 shares of common stock on a post-split basis (194,486 shares on a pre-split basis) and warrants to acquire 14,863 shares of common stock on a post-split basis (89,180 shares on a pre-split basis) to Clean Diesel’s financial advisor Innovator Capital as payment for fees.

As described under Item 1.01, we assumed CSI’s obligations under the Registration Rights Agreement. The Registration Rights Agreement provides for certain demand and “piggyback” registration rights, and requires us to register all the shares of Clean Diesel common stock issued in the Merger to the former holders of CSI’s Class B common stock (which was issued upon conversion of CSI’s secured convertible notes immediately prior to the Merger).

In addition to the unregistered shares of Clean Diesel common stock and warrants to purchase Clean Diesel common stock issued in the Merger, on October 15, 2010, we also completed our Regulation S private placement described in Item 1.01 above, and sold units consisting of 109,020 shares of our common stock on a post-split basis (654,118 on a pre-split basis) and warrants to purchase up to 166,666 shares of our common stock on a post-split basis (1,000,000 on a pre-split basis). All of these shares of Clean Diesel common stock and warrants to purchase Clean Diesel common stock were issued in reliance upon the exemption from the registration requirements of the Act pursuant to Regulation S promulgated thereunder.

Neither this Current Report on Form 8-K nor the exhibits attached hereto is an offer to sell or the solicitation of an offer to buy shares of our common stock or any other security.

The disclosure in Item 1.01 of this Current Report on Form 8-K is incorporated by reference into this Item.

Item 3.03 Material Modification to Rights of Security Holders.

As contemplated by the Merger Agreement and described in the Registration Statement, at the annual meeting held on October 12, 2010, Clean Diesel’s stockholders approved a reverse stock split with the ratio to be determined by the Board of Directors. Following approval by the Clean Diesel stockholders, the Board of Directors authorized a one-for-six reverse stock split, which took effect on October 15, 2010, with respect to all shares of Clean Diesel common stock outstanding as of October 15, 2010.

The foregoing description of the amendment to Clean Diesel’s Restated Certificate of Incorporation contained in this Item 3.03 does not purport to be complete and is qualified in its entirety by reference to the Certificate of Amendment, which is filed as Exhibit 3.1 hereto and is incorporated herein by reference.

On October 15, 2010, Clean Diesel issued a press release announcing the ratio of the reverse stock split, among other items. A copy of the press release is attached hereto as Exhibit 99.1.

Item 5.01 Changes in Control of Registrant
 

Reference is made to the disclosure set forth under Item 2.01 of this Current Report on Form 8-K, which disclosure is incorporated herein by reference.

For legal purposes, Clean Diesel acquired CSI, although the combination will be accounted for as a reverse merger with CSI deemed to be the “acquiror” for accounting and financial reporting purposes.
