As previously disclosed in the Current Report on Form 8-K filed on December 1, 2014 with the Securities and Exchange Commission (the “SEC”), on December 1, 2014, Cambridge Capital Acquisition Corporation (“Cambridge”) entered into a Business Combination Agreement (the “Merger Agreement”) with Cambridge Holdco, Inc. (“Holdco”), Cambridge Merger Sub, Inc. (“Merger Sub”), Parakou Tankers, Inc. (“Parakou”) and Mr. Por Liu. Pursuant to the Merger Agreement, subject to the satisfaction or waiver of certain conditions, (i) Cambridge will be merged with and into Holdco, with Holdco surviving the Merger (the “Cambridge Merger”) and (ii) Merger Sub will be merged with and into Parakou, with Parakou surviving the Merger and becoming the wholly-owned subsidiary of Holdco (the “Parakou Merger” and, together with the Cambridge Merger, the “Mergers”).

On April 21, 2015, Cambridge entered into Amendment No. 1 to the Merger Agreement (the “Amendment”), with Holdco, Merger Sub, Parakou and Mr. Por Liu. The amendments to the Merger Agreement contained in the Amendment include the following:

Additionally, on April 21, 2015, Holdco entered into Amendment No. 1 to the Shareholders Agreement (the “Shareholders Agreement Amendment”) with Mr. Por Liu and Mr. Benjamin Gordon, pursuant to which (i) Mr. Por Liu will have the right to designate for nomination to the Holdco board: (A) up to three individuals if Mr. Por Liu owns 20% or more of the issued and outstanding Holdco Common Shares, (B) up to two individuals if Mr. Por Liu owns less than 20% but 15% or more of the issued and outstanding Holdco Common Shares and (C) one individual if Mr. Por Liu owns less than 15% but 10% or more of the issued and outstanding Holdco Common Shares; and (ii) at the first meeting of shareholders of Holdco after the consummation of the mergers at which directors are elected to the board, if there is a vacancy on the board or the board determines not to recommend for election to the board a director who has been on its board, Mr. Benjamin Gordon will have the right to designate one individual for nomination to the Holdco board.

The above summary of the amendments is qualified in its entirety by reference to the full text of the Amendment and the Shareholders Agreement Amendment, which are attached hereto as Exhibits 10.1 and 10.2, respectively, and are incorporated herein by reference. You are urged to read the entire Merger Agreement (as filed with Cambridge’s definitive Proxy Statement/Prospectus), the Amendment, the Shareholders Agreement Amendment and the other exhibits attached hereto.

On April 22, 2015, the Company issued a press release announcing (i) its entry into the Amendment and (ii) that it intends to convene and then adjourn, without conducting any business, its special meeting of stockholders until Friday, April 24, 2015 at 4:00 p.m. Eastern Time, in order to give its stockholders additional time to consider the supplemental proxy materials and to vote on the proposals to be considered at the special meeting. The special meeting will still be held at the offices of DLA Piper LLP (US), 200 South Biscayne Boulevard, Suite 2500, Miami, Florida 33131-5341.

These forward-looking statements and factors that may cause such differences include, without limitation, the satisfaction of the closing conditions to the Business Combination; approval of the Business Combination by the Company’s stockholders; Cambridge’s and Parakou’s expectations with respect to future performance, growth and anticipated acquisitions; the anticipated financial impact of the Business Combination; ability to recognize the anticipated benefits of the Business Combination; costs related to the Business Combination; volatility in charter rates and profitability; demand for shipping of refined petroleum products; global economic conditions; changes in fuel prices; geopolitical events and regulatory changes; damages to vessels; acts of piracy, political instability, terrorist or other attacks, war or international hostilities; loss of key personnel; delays in deliveries of any newbuild product tankers; difficulty managing planned growth properly; seasonal and exchange rate fluctuations; access to additional financing; changes in tax laws; weather and natural disasters; changing interpretations of generally accepted accounting principles; inquiries and investigations and related litigation; continued compliance with government regulations; and other risks and uncertainties indicated from time to time in filings with the Securities and Exchange Commission (“SEC”) by the Company or Holdco. Readers are cautioned not to place undue reliance upon any forward-looking statements, which speak only as of the date made.

Additional Information and Where to Find It

The proposed Business Combination will be submitted to the stockholders of the Company for their consideration. In connection with the proposed Business Combination, Holdco has filed with the SEC the Registration Statement, which includes a proxy statement/prospectus for the stockholders of the Company. The Company and Holdco urge investors, stockholders and other interested persons to read the proxy statement/prospectus, as well as other documents filed with the SEC, because these documents contain important information. Such persons can also read the Company’s final prospectus, dated December 17, 2013, and the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2014, for a description of the

security holdings of the Company’s officers and directors and of EarlyBirdCapital, Inc. (“EBC”) and their respective interests as security holders in the successful consummation of the transactions described herein. The Company’s definitive proxy statement, as included in Holdco’s Registration Statement, has been mailed to stockholders of the Company.

Participants in Solicitation

EBC, the managing underwriter of the Company’s initial public offering consummated in December 2013, is acting as the Company’s investment banker in the Business Combination, for which it will receive a fee. Additionally, Cowen and Company, LLC (“Cowen”) is also assisting the Company in connection with the Business Combination, for which it will receive a fee.
