	 	Re:	Initial Public Offering 

 Gentlemen: 
 This letter is being delivered to you in accordance with the Underwriting Agreement (the “Underwriting Agreement”) entered into by
and between Capitol Acquisition Corp., a Delaware corporation (the “Company”), and Citigroup Global Markets Inc., as Representative (the “Representative”) of the several Underwriters named in Schedule
I thereto (the “Underwriters”), relating to an underwritten initial public offering (the “IPO”) of the Company’s units (the “Units”), each comprised of one share of the
Company’s common stock, par value $0.0001 per share (the “Common Stock”), and one warrant, each warrant exercisable for one share of Common Stock (each, a “Warrant”). Certain capitalized terms
used herein are defined in paragraph 15 hereof. 
 In order to induce the Company and the Underwriters to enter into the Underwriting
Agreement and to proceed with the IPO, and in recognition of the benefit that such IPO will confer upon the undersigned as a stockholder of the Company, and for other good and valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the undersigned hereby agrees with the Company as follows: 
 1. If the Company solicits approval of its stockholders of a
Business Combination, the undersigned will (i) vote all shares of Founders’ Common Stock beneficially owned by him, her or it in accordance with the majority of the votes cast by the holders of the IPO Shares and (ii) vote all other
shares of the Company’s Common Stock that may be beneficially acquired by him, her or it in the IPO, any private placement or in the aftermarket in favor of such Business Combination. 







 2. In the event that the Company fails to consummate a Business Combination within 24 months from the
effective date (“Effective Date”) of the registration statement relating to the IPO, the undersigned will, as promptly as possible, (i) cause the Trust Fund to be liquidated and distributed to the holders of IPO Shares and
(ii) cause the Company to liquidate as soon as reasonably practicable. The undersigned hereby waives any and all right, title, interest or claim of any kind in or to any distribution of the Trust Fund and any remaining net assets of the Company
as a result of such liquidation with respect to his shares of Founders’ Common Stock (“Claim”) and hereby 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 and will not seek recourse against the Trust Fund for any reason whatsoever. In the event of the liquidation of the Trust Fund, the undersigned agrees to indemnify and hold harmless the Company against any and all loss, liability, claims,
damage and expense whatsoever (including, but not limited to, any and all legal or other expenses reasonably incurred in investigating, preparing or defending against any litigation, whether pending or threatened, or any claim whatsoever) which the
Company may become subject as a result of any claim by any vendor or other person who is owed money by the Company for services rendered or products sold or contracted for, or by any target business, but only to the extent necessary to ensure that
such loss, liability, claim, damage or expense does not reduce the amount of funds in the Trust Fund; provided that such indemnity shall not apply (i) if such vendor or prospective target business does not execute a valid and enforceable
agreement waiving any claims against the Trust Fund, or (ii) as to any claims under the Company’s obligation to indemnify the Underwriters against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the
“Securities Act”). The undersigned acknowledges and agrees that there will be no distribution from the Trust Fund with respect to any warrants, all rights of which will terminate on the Company’s liquidation. 
 3. In order to minimize potential conflicts of interest which may arise from multiple corporate affiliations, the undersigned has agreed, until the
earliest of the consummation by the Company of a Business Combination, the liquidation of the Company or such time as the undersigned ceases to be an officer, to present to the Company for its consideration, prior to presentation to any other
entity, any business opportunity in excess of approximately $190 million which may reasonably be required to be presented to the Company under Delaware law, subject to any pre-existing fiduciary or contractual obligations the undersigned may have.
Decisions by the Company to release the undersigned to pursue any specific business opportunity will be made solely by a majority of the Company’s disinterested directors. 
 4. The undersigned acknowledges and agrees that prior to entering into (i) a Business Combination with a target business that is, or has been within
the past five years, affiliated with any of the Insiders or special advisors of the Company or their affiliates, including an entity that is either a portfolio company, or has otherwise received a material financial investment from, any private
equity fund or investment company (or an affiliate thereof) that is affiliated with such individuals; or (ii) a Business Combination 

  

 2 








 
where the Company acquires less than 100% of a target business and any of the Insiders or special advisors of the Company or their affiliates acquire the
remaining portion of such target business; such transaction must be approved by a majority of the Company’s disinterested independent directors and the Company must obtain an opinion from an independent investment banking firm that such
Business Combination is fair to the Company’s unaffiliated stockholders from a financial point of view. 
 5. Neither the undersigned,
any member of the family of the undersigned, nor any affiliate of the undersigned will be entitled to receive and will not accept any compensation or other cash payment for services rendered to the Company prior to or in connection with the
consummation of the Business Combination; provided that the Company shall be allowed to repay a non-interest bearing loan in an aggregate amount of $95,000 made to the Company by the undersigned to cover the IPO expenses. The undersigned and any
affiliate of the undersigned shall also be entitled to reimbursement from the Company for their out-of-pocket expenses incurred in connection with identifying, investigating and consummating a Business Combination. 
 6. Neither the undersigned, any member of the family of the undersigned, nor any affiliate of the undersigned will be entitled to receive or accept a
finder’s fee or any other compensation in the event the undersigned, any member of the family of the undersigned or any affiliate of the undersigned originates a Business Combination. 
 7. The undersigned will escrow all of his shares of Founders’ Common Stock until one year after the consummation by the Company of a Business
Combination subject to the terms of a Stock Escrow Agreement which the Company will enter into with the undersigned and an escrow agent acceptable to the Company. 
 8. The undersigned agrees that until the Company consummates a Business Combination, the undersigned’s Sponsors’ Warrants will be subject to the transfer restrictions described in the Subscription Agreement
relating to the undersigned’s Sponsors’ Warrants. 
 9. The undersigned agrees to be the Chief Executive Officer, Secretary and
Director of the Company until the earlier of the consummation by the Company of a Business Combination or the liquidation of the Company. The undersigned’s biographical information furnished to the Company and Citigroup and attached hereto as
