Ladies and Gentlemen:

The undersigned officer and/or director of K Road Acquisition Corporation (the “Company”), in consideration of Credit Suisse Securities (USA) LLC (“Credit Suisse” or the “Underwriter”) entering into an agreement to underwrite an initial public offering (the “IPO”) of 30,000,000 Units (34,500,000 if the over-allotment option is exercised in full), each unit comprised of one share of the Company’s Common Stock (the “Common Stock”) and one warrant exercisable for one share of the Company’s Common Stock (“Warrant”) and embarking on, undertaking and continuing to participate in the IPO process, hereby agrees as follows (certain capitalized terms used herein are defined in paragraph 11 hereof):

1. If the Company solicits approval of its stockholders of an Extended Period or a Business Combination, the undersigned will: (i) vote any shares of Common Stock acquired in or following the IPO in favor of the Extended Period and the Business Combination and (ii) vote any shares of Common Stock acquired in or following the IPO in favor of an amendment to the Company’s amended and restated certificate of incorporation (the “Amended and Restated Certificate of Incorporation”)  to provide for perpetual existence of the Company in the event the Business Combination is approved.

2. (a) In the event that the Company fails to consummate a Business Combination within 24 months from the effective date (the “Effective Date”) of the registration statement relating to the IPO, or 30 months from the Effective Date in the event the Extended Period is approved by the Company’s stockholders (the later date being the “Termination Date”), the undersigned shall, in accordance with all applicable requirements of the Delaware General Corporation Law, take all action reasonably within his power to liquidate the Company and distribute all funds held in the Trust Account to the Public Stockholders as soon as reasonably practicable following the Termination Date in the manner and subject to the Trust Agreement. In addition, from and after the Termination Date, the undersigned will, in accordance with the Company’s Amended and Restated Certificate of Incorporation, take all action reasonably within his power to limit the Company’s activities to winding up its affairs and to dissolving the Company and liquidating the Trust Account.

(b) Except with respect to any of the IPO Shares acquired by the undersigned in connection with or following the IPO, the undersigned hereby irrevocably: (i) waives any and all right, title, interest, cause of action or claim of any kind (a “Claim”) in or to all funds in the Trust Account and any remaining net assets of the Company upon liquidation of the Trust Account and dissolution of the Company; (ii) waives any Claim the undersigned may have in the future as a result of, or arising out of, any contracts or agreements with the Company, which Claim would reduce, encumber or otherwise adversely affect the amounts held in the Trust Account; and (iii) agrees that the undersigned will not seek recourse (legal, equitable or otherwise) against the Trust Account for any reason whatsoever.  The

4. The undersigned will take all action reasonably within his power to ensure that neither the undersigned nor any Affiliate will be entitled to receive and will not accept any compensation for services rendered to the Company prior to or in connection with the consummation of the Business Combination; provided that the undersigned shall be entitled to reimbursement from the Company for his out-of-pocket expenses incurred in connection with seeking and consummating a Business Combination.
