this Agreement with an attorney of his, her or its own choosing.


 


3.5. Absence
of Litigation. As of the date hereof, there is no action, suit, investigation, complaint or other proceeding pending against

(b) Each
Stockholder agrees that any shares of the Company and any other shares of capital stock or other equity of the Company that such
Stockholder purchases or otherwise acquires or with respect to which such Stockholder otherwise acquires voting power shall be
subject to the terms and conditions of this Agreement to the same extent as if they constituted the Stockholder Shares as of the
date of this Agreement, and such Stockholder shall promptly notify the Company of the existence of any such after acquired Stockholder
Shares. In the event of any stock split, stock dividend, merger, reorganization, recapitalization, reclassification, combination,
exchange of shares or the like of the capital stock of the Company affecting the Shares, the terms of this Agreement shall apply
to the resulting securities.


 


(c) “Transfer”
means (i) any direct or indirect sale, tender pursuant to a tender or exchange offer, assignment, encumbrance, disposition, pledge,
hypothecation, gift or other transfer (by operation of law or otherwise), either voluntary or involuntary, of any capital stock
or any interest (including any beneficial ownership interest) in any capital stock (including the right or power to vote any capital
stock) or (ii) in respect of any capital stock or interest (including any beneficial ownership interest) in any capital stock,
to directly or indirectly enter into any swap, derivative or other agreement, transaction or series of transactions, in each case
referred to in this clause (ii) that has an exercise or conversion privilege or a settlement or payment mechanism determined with
reference to, or derived from the value of, such capital stock, and that hedges or transfers, in whole or in part, directly or
indirectly, the economic consequences of such capital stock or interest (including any beneficial ownership interest) in capital
stock, whether any such transaction, swap, derivative or series of transactions is to be settled by delivery of securities, in
cash or otherwise. A “Transfer” shall not include the transfer of (A) Stockholder Shares by a Stockholder to a controlled
Affiliate of such Stockholder (each such transferee a “Permitted Transferee” and each such transfer, a “Permitted
Transfer”), or (B) Stockholder Shares by a Stockholder after receipt of the Company Stockholder Approval. As a condition
to any Permitted Transfer, the applicable Permitted Transferee shall be required to become a party to this Agreement by signing
a joinder agreement hereto in form and substance reasonably satisfactory to Parent (each a “Joinder”). References
to “the parties hereto” and similar references shall be deemed to include any later party signing a Joinder. For the
avoidance of doubt, nothing in this Agreement shall restrict any direct or indirect Transfers of any equity interests in such Stockholder.


 


(d) Each
Stockholder hereby agrees not to, and not to permit any entity under such Stockholder’s control to, deposit any of such Stockholder’s
Stockholder Shares in a voting trust, enter into a voting trust or subject any of the Stockholder Shares owned beneficially or
of record by such Stockholder to any arrangement with respect to the voting of such Stockholder Shares other than agreements entered
into with the Investor.


 


(e) Any
Transfer or attempted Transfer of any Stockholder Shares in violation of this Section 4 shall, to the fullest extent permitted
by applicable Law, be null and void ab initio. If any involuntary Transfer of any of Stockholder’s Stockholder Shares shall occur,
the transferee (which term, as used herein, shall include any and all transferees and subsequent transferees of the initial transferee)
shall take and hold such Stockholder Shares subject to all of the restrictions, liabilities and rights under this Agreement, which
shall continue in full force and effect until valid termination of this Agreement.

of record, by such Stockholder on the day before the date of such public disclosure.


 


(d) “Profit”

Consideration.


 


(e) “Profit
Share Recipient” means each of the Investor and the Sellers’ Representative.

as of the date of consummation of such Superior Proposal. The fair market value of any non-cash consideration consisting of:

(ii) non-cash
consideration which is other than securities of the type specified in subclause (i) above shall be equal to the amount a reasonable,
willing buyer would pay a reasonable, willing seller, taking into account the nature and terms of such property as separately agreed
to in good faith by the Investor or the Sellers’ Representative, as applicable, and each Stockholder. In the event a Profit
Sharing Recipient and a Stockholder fail to agree within fifteen (15) Business Days as to the fair market value of such non-cash
consideration, then such Profit Sharing Recipient and such Stockholder shall submit a proposal for determination, which determination
shall be binding on all parties to the dispute, to a nationally recognized independent investment banking firm mutually agreed
upon by the parties within ten (10) Business Days of the event requiring selection of such banking firm, and such bank shall be
requested to select, within fifteen (15) Business Days following receipt of the last proposal, the proposal which is closest in
value to the bank’s determination of fair market value and the value referred to in the selected proposal shall be the fair
market value of such non-cash consideration binding on such Profit Sharing Recipient and such Stockholder; provided, however,
that if the parties are unable to agree within five (5) Business Days after the date of the event requiring such selection as to
the investment banking firm, then such Profit Sharing Recipient and such Stockholder shall each select one firm, and those firms
shall select a third investment banking firm, which third firm shall make such determination, which determination shall be binding
on all parties to this Agreement. The fees and expenses of the investment banking firm shall be borne by the party whose proposal
is not selected by the relevant bank for the purpose of determining fair market value. Save for the foregoing, each party to the
dispute shall be solely responsible for all fees, expenses, costs and charges incurred by or on behalf of it in connection with
such determination.


 


5.4. In
the event that the Company shall declare and pay a stock or extraordinary dividend or other distribution, or effect a stock split,
reverse stock split, reclassification, reorganization, recapitalization, combination or other like change with respect to Stockholder
Shares, the calculations set forth in this Section 5 shall be adjusted to reflect fully such dividend, distribution, stock
split, reclassification, reorganization, recapitalization, combination or other like change and the value of any such dividend,
distribution, stock split, reclassification, reorganization, recapitalization, combination or other like change (including any
residual interest in the Company whether represented by the Stockholder Shares or other securities of the Company) shall be considered
in determining the Profit as provided in this Section 5.


 


5.5. Any
payment to the Profit Sharing Recipients hereunder shall be made in the same form as the consideration received by the applicable
Stockholder from the Superior Proposal (and, if the consideration so received was in more than one form, then in the same proportion
as the forms of consideration so received); provided, however, that each Stockholder shall pay in cash any amount
of Profit attributed to Stockholder’s residual or remaining interest, if any, in the Company. Any payment to be made hereunder
(i) in cash, shall be paid by wire transfer of immediately available funds to an account specified in writing by the applicable
Profit Sharing Recipient, and (ii) in the form of securities or other property, shall be paid through delivery of the securities
or other property received, suitably endorsed for transfer, and free and clear of any and all Liens (other than those imposed by,
through or under the Superior Proposal or as required by law, as the case may be).


 


5.6. Each
Stockholder agrees that, in connection with any Superior Proposal, the price per share of Common Stock received by, and the form
of consideration or, if applicable, the right to make an election as to the form of consideration received by, such Stockholder
in such Superior Proposal shall be identical to the price per share of Common Stock received by, and the form of consideration
or, if applicable, the right to make an election as to the form of consideration received by, the other holders of Common Stock
in connection with such Superior Proposal.


 






    -9-


     


    

 


5.7. Notwithstanding
anything else contained herein, in the case of any Superior Proposal that is not treated as a fully taxable transaction for U.S.
federal income tax purposes where all equity interests in the Company held by Capitol Acquisition Founder IV, LLC (“Capitol
Founder”) or Capitol Acquisition Management IV, LLC (“Capitol Management”) are converted to cash,
the amount of cash or other property required to be delivered by Capitol Founder or Capitol Management, as applicable, to a Profit
Share Recipient pursuant to this Section 5 shall be reduced by the amount of Tax (if any) that would be payable by Capitol
Founder or Capitol Management, as applicable, in connection with its receipt and payment to such Profit Share Recipient of an amount
of cash and other property equal to the portion of its Profit payable to such Profit Share Recipient, taking into account any contemporaneous
tax savings (including reduced gain in connection with the Superior Proposal) resulting from payment over to such Profit Share
Recipient, assuming for this purpose that Capitol Founder or Capitol Management, as applicable, is subject to the highest combined
U.S. federal, state and local income tax rates applicable to an individual tax resident in New York, NY with respect to the type
of income in question; provided that such Stockholder shall provide such Profit Share Recipient with a reasonable explanation and
calculation of the Tax amount.

This Agreement may be executed in two or more counterparts, all of which shall be considered one and the same agreement and shall

having signed a counterpart, it being understood that all parties need not sign the same counterpart. The exchange of copies of
this Agreement and of signature pages by facsimile or in .pdf format by e-mail shall constitute effective execution and delivery

6.3. Entire
Agreement; No Third Party Beneficiaries. This Agreement, including the documents and the instruments referred to herein (a) constitutes
the entire agreement, and supersedes all prior agreements and understandings, both written and oral, among the parties hereto with
respect to the subject matter hereof and no party hereto is relying on any other oral or written representation, agreement or understanding
and no party makes any express or implied representation or warranty in connection with the transactions contemplated by this Agreement
other than as set forth in this Agreement, and (b) is not intended to confer upon any Person other than the parties hereto any
rights or remedies; provided, however, that Sellers’ Representative is an express third party beneficiary of this Agreement
and shall be entitled to specific performance of Stockholders’ obligations hereunder in accordance with Section 6.


 


6.4. Governing
Law; Consent to Jurisdiction. This Agreement and any claim, controversy or dispute arising out of or relating to this Agreement
and the transactions contemplated hereby, and/or the interpretation and enforcement of the rights and duties of the parties hereunder,
shall be governed by and construed in accordance with the Laws of the State of Delaware without giving effect to any choice or
conflict of laws provision or rule that would result in the application of the Laws of any other jurisdiction. Each of the parties
irrevocably submits to the exclusive jurisdiction of the state courts of the Delaware Court of Chancery or, if the Delaware Court
of Chancery declines to accept jurisdiction over a particular matter, any federal court located in the State of Delaware (and,
in each case, any applicable appellate courts therefrom) for purposes of any Proceeding directly or indirectly arising out of or
related in any way to this Agreement or the transactions contemplated hereby, and the interpretation and enforcement of the rights
and duties of the parties under this Agreement (and agrees not to commence or support any Person in any such Proceeding relating
thereto except in such courts). Each of the parties further irrevocably waives any objection which such party may now or hereafter
have to the laying of the venue of any such Proceeding in such courts and shall not plead or claim in any such court that any such
Proceeding brought in such court has been brought in an inconvenient forum. Service of process with respect thereto may be made
upon any party by mailing a copy thereof by registered mail to such party at its address as provided in Section 6.1. EACH
OF THE PARTIES HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT THAT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF
ANY ACTION DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATED IN ANY WAY TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY
OR THE INTERPRETATION AND ENFORCEMENT OF THE RIGHTS AND DUTIES OF THE PARTIES UNDER THIS AGREEMENT. NOTWITHSTANDING ANYTHING HEREIN
TO THE CONTRARY.

6.5. Amendments
and Supplements. This Agreement may be amended or supplemented at any time by additional written agreements signed by the Investor
and any one or more Stockholder(s), which written agreement(s) shall be effective against each of the parties that has signed such
written agreement(s), as may be determined by such parties to be necessary, desirable or expedient to further the purpose of this
Agreement or to clarify the intention of the parties.


 


6.6. Failure
or Delay Not Waiver; Remedies Cumulative. No provision of this Agreement may be waived except by a written instrument signed
by the party against whom such waiver is to be effective. Any agreement on the part of a party to any such waiver shall be valid
only if set forth in a written instrument executed and delivered by a duly authorized officer on behalf of such party. No failure
or delay on the party of any party in the exercise of any right hereunder shall impair such right or be construed to be a waiver
of or acquiescence in, any breach of any representation, warranty or agreement herein, nor shall any single or partial exercise
of any such right preclude any other or further exercise thereof or of any other right. All rights and remedies existing under
this Agreement are cumulative to, and not exclusive of any rights or remedies otherwise available.


 


6.7. Assignment.
Neither this Agreement nor any of the rights, interests or obligations under this Agreement shall be assigned, in whole or in part,
by operation of Law or otherwise without the prior written consent of the Investor (in the case of an assignment by any Stockholder)
or each Stockholder (in the case of any assignment by the Investor). Any purported assignment in violation of the preceding sentence
shall be null and void ab initio. Subject to the preceding two sentences, this Agreement will be binding upon, inure to
the benefit of, and be enforceable by, the parties and their respective successors and permitted assigns.


 


6.8. Headings.
The headings and table of contents contained in this Agreement are for reference purposes only and shall not affect in any way
the meaning or interpretation of this Agreement.


 


6.9. Severability.
If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any rule of Law or public
policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect, insofar as the
foregoing can be accomplished without materially affecting the economic benefits anticipated by the parties to this Agreement.
Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto
shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible
to the fullest extent permitted by applicable Law in an acceptable manner to the end that the transactions contemplated hereby
are fulfilled to the greatest extent possible.

6.10. Specific
Performance.


 


(a) The
parties agree that irreparable damage would occur and that the parties would not have any adequate remedy at Law in the event that
any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached.
It is accordingly agreed that the parties shall, prior to termination in accordance with Section 6.15, be entitled
to an injunction or injunctions, or any other appropriate form of equitable relief, without proving actual damages, to prevent
breaches of this Agreement and to seek to enforce specifically the terms and provisions of this Agreement, this being in addition
to any other remedy to which they are entitled at law or in equity. Each of the parties hereto (i) agrees that it shall not oppose
the granting of any such relief and will not raise any objections to the availability of the equitable remedy of specific performance
to prevent or restrain breaches or threatened breaches of, or to enforce compliance with, the covenants and obligations of such
Stockholder under this Agreement and (ii) hereby irrevocably waives any requirement for the security or posting of any bond in
connection with any such relief (it is understood that clause (i) of this sentence is not intended to, and shall not, preclude
any party hereto from litigating on the merits the substantive claim to which such remedy relates).


 


(b)
The parties hereto further agree that (i) by seeking the remedies provided for in this Section 6.10, no party shall in any
respect waive it rights to seek any other form of relief that may be available to it under this Agreement (including damages) in
the event that this Agreement has been terminated or in the event that the remedies provided for in this Section 6.10 are
not available or otherwise are not granted, and (ii) nothing set forth in this Agreement shall require a party to institute any
Proceeding (or limit a party’s right to institute Proceedings for) for specific performance under this Section 6.10
prior to pursuing any other form of relief referred to in the preceding clause (i).


 


6.11. WAIVER
OF JURY TRIAL. EACH STOCKHOLDER AND THE INVESTOR ACKNOWLEDGE AND AGREE THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS AGREEMENT
IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE EACH SUCH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES
ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER BASED ON CONTRACT, TORT
OR OTHERWISE) DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT AND ANY OF THE DOCUMENTS AND INSTRUMENTS REFERRED
TO HEREIN OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY, OR THE ACTIONS OF A STOCKHOLDER OR THE INVESTOR IN THE NEGOTIATION,
ADMINISTRATION, PERFORMANCE AND ENFORCEMENT OF THIS AGREEMENT. EACH STOCKHOLDER AND THE INVESTOR CERTIFY AND ACKNOWLEDGE THAT (a)
NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT,
IN THE EVENT OF ANY ACTION, LITIGATION OR PROCEEDING, SEEK TO ENFORCE THE FOREGOING WAIVER, (b) IT UNDERSTANDS AND HAS CONSIDERED
THE IMPLICATIONS OF THIS WAIVER, (c) IT MAKES THIS WAIVER VOLUNTARILY AND (d) IT HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT
BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 6.11.

6.12. Costs
and Expenses. Each party to this Agreement will pay his, her or its own costs and expenses (including legal, accounting and
other fees) relating to the negotiation, execution, delivery and performance of this Agreement.


 


6.13. No
Joint Venture. Nothing contained in this Agreement shall be deemed or construed as creating a joint venture or partnership
between any of the parties hereto. Except as otherwise provide in Section 2, no party is by virtue of this Agreement authorized
as an agent, employee or legal representative of any other party. Without in any way limiting the rights or obligations of any
party hereto under this Agreement, prior to the consummation of the Closing and the Acquisition Closing (i) no party shall have
the power by virtue of this Agreement to control the activities and operations of any other, and (ii) except as otherwise provided
in Section 2, no party shall have any power or authority by virtue of this Agreement to bind or commit any other party.
No party shall hold itself out as having any authority or relationship in contravention of this Section 6.13.


 


6.14. Public
Announcements. Except as required by Law or by the requirements of any stock exchange on which the securities of any Stockholder
or any of its Affiliates are listed, no Stockholder will make, or cause to be made, any press release or public announcement in
respect of this Agreement or otherwise communicate with any news media with respect to the foregoing without the Investor’s
prior written consent. Each Stockholder consents to and authorizes the publication and disclosure by the Company of such Stockholder’s
identity and holding of the Stockholder Shares, and the terms of this Agreement (including, for avoidance of doubt, the disclosure
of this Agreement), in any press release, the Proxy Statement, and any other disclosure document required in connection with the
Investment, the Investment Agreement, or any transactions contemplated hereby or thereby.


 


6.15. Termination.
This Agreement shall terminate on the earliest to occur of (a) the mutual agreement of each of the parties hereto and the Sellers’
Representative, (b) the consummation of the Closing and the Acquisition Closing and (c) the termination of the Investment
Agreement in accordance with its terms; provided that (i) if the Investment Agreement is terminated under circumstances
where the Investor is or may be entitled to receive the Termination Fee pursuant to Section 7.2(b) of the Investment Agreement,
then (A) Section 5 shall survive any termination of this Agreement and (B) Section 4 shall survive so long as Section
5 survives, (ii) nothing herein shall relieve or release any party hereto from any obligations or liabilities for any willful
or intentional breach of this Agreement prior to its termination and (iii) this Section 6 shall survive any termination
of this Agreement.


 


6.16. Mutual
Drafting; Interpretation. The provisions of Sections 1.2 and 7.4(i) of the Investment Agreement shall apply mutatis mutandis
to this Agreement.


 


6.17. Capacity
as Stockholder. Each Stockholder signs this Agreement solely in such Stockholder’s capacity as a stockholder of the Company,
and not in such Stockholder’s or any of its Affiliates’ capacity as a director (including “director by deputization”),
officer or employee of the Company, if applicable. Nothing herein shall be construed to limit or affect any actions or inactions
by any representative of Stockholder serving as a director of the Company or any Subsidiary of the Company, acting in such person’s
capacity as a director of the Company or any Subsidiary of the Company, including taking any action with respect to any Acquisition
Proposal as a member of such Board (it being understood and agreed that the Investment Agreement contains provisions that govern
the actions or inactions by the directors of the Company with respect to the Investment and the other Contemplated Transactions).
