The
undersigned  officer and

underwriters in connection with the initial public offering of the securities
of the Company (“IPO”), hereby agrees as follows:


 


1.             Agreements of
Stockholders


 


(a)           The undersigned hereby waives any
right to receive distributions (other than with respect to Common Stock or any
shares of Common Stock underlying units the undersigned may purchase in
connection with the IPO or in the after market) upon the liquidation of the
Trust Fund (as defined in the Certificate of Incorporation of the Company (as
amended, the “Certificate”; capitalized terms used herein but not
defined herein have the meaning set forth in the Certificate)), or as part of
any plan of dissolution and distribution required in the event the Company does
not consummate a Business Combination by the Termination Date.


 


(b)           The undersigned hereby waives any
right set forth in the Certificate to demand conversion of the undersigned’s
shares of Common Stock into cash (other than with respect to Common Stock or
any shares of Common Stock underlying units the


 

















 


undersigned may purchase in connection with
the IPO or in the after market) in the event a Business Combination is approved
by the Company’s stockholders.


 


(c)           In connection with the stockholder
vote required to approve a Business Combination, the undersigned shall vote any
shares of Common Stock then owned by the undersigned in accordance with the
majority of the shares of Common Stock voted by the Company’s public
stockholders.  In connection with the
stockholder vote for the Company’s plan of dissolution and distribution, if
any, required as a result of the Company’s failure to consummate a Business
Combination by the Termination Date, the undersigned shall vote any shares of
Common Stock then owned by the undersigned in favor of such dissolution and
distribution.


 


(d)           The undersigned and any affiliate of
the undersigned will not be entitled to receive from the Company, and will not
accept from the Company, any compensation (including finder’s or consulting
fees) for services rendered to the Company prior to or in connection with the
consummation of a Business Combination (except as described in the registration
statement filed with and declared effective by the Securities and Exchange
Commission in connection with the IPO (the “Registration Statement”).


 


(e)           The undersigned will escrow the shares
of Common Stock owned by the undersigned immediately prior to the IPO pursuant
to a stock escrow agreement until the earliest of (i) one year from the
completion of a Business Combination, (ii) the Company’s liquidation and
(iii) the consummation of a business combination which results in all of
the Company’s stockholders having the right to exchange their shares of Common
Stock for cash, securities or other property subsequent to the Company’s
consummating a Business Combination.


 


2.             Agreements of
Directors and Officers


 


(a)           In the event that the Company does
not consummate a Business Combination by the Termination Date, in the event the
undersigned is a director of the Company, the undersigned, in his capacity as a
Director of the Company, (i) acknowledges the requirement set forth in the
Certificate that the Board of Directors of the Company shall adopt, within 15
days after the Termination Date, a resolution finding the dissolution of the
Company advisable and provide notices to the Company’s stockholders as required
by § 275(a) of the Delaware General Corporate Law as soon as reasonably
practicable thereafter and (ii) will take all reasonable actions within
the undersigned’s power to effect such dissolution of the Company under the
circumstances contemplated by the Certificate provided that at the time of such
liquidation and dissolution the undersigned is a director.


 


(b)           In order to minimize potential
conflicts of interest which may arise from multiple affiliations, in the event
the undersigned is an officer of the Company, the undersigned, in his capacity
as an officer of the Company, agrees to present to the Company for its
consideration, prior to presentation to any other person or entity, any
suitable opportunity to acquire an operating business, until the earlier of the
consummation by the Company of a Business Combination, the liquidation of the
Company or until such time as the undersigned is

not an officer of the Company, subject to any
pre-existing fiduciary and contractual obligations the undersigned might have.


 


(c)           The undersigned’s biographical
information set forth in the Registration Statement is true and accurate in all
respects, does not omit any material information with respect to the
undersigned’s background and contains all of the information required to be
disclosed pursuant to Item 401 of Regulation S-K, promulgated under the
Securities Act of 1933.  The undersigned’s
Director’s and Officer’s Questionnaire furnished to the Company in connection
with the Registration Statement is true and accurate in all respects.  The undersigned represents and warrants that,
except as disclosed in the undersigned’s Director’s and Officer’s
Questionnaire:


 


i.              the undersigned is
not subject to or a respondent in any legal action for, any injunction,
cease-and-desist order or order or stipulation to desist or refrain from any
act or practice relating to the offering of securities in any jurisdiction;


 


ii.             the undersigned
has never been convicted of or pleaded guilty to any crime (i) involving
any fraud or (ii) relating to any financial transaction or handling of
funds of another person, or (iii) pertaining to any dealings in any
securities, and is not currently a defendant in any such criminal proceeding;
and


 


iii.            the undersigned
has never been suspended or expelled from membership in any securities or
commodities exchange or association or had a securities or commodities license
or registration denied, suspended or revoked.


 


(d)           The undersigned has full right and
power, without violating any agreement by which he is bound, to enter into this
letter agreement and to serve as the Executive Vice President, General Counsel
and Corporate Secretary.


 


3.             Reimbursement of
Vendor Obligations


 


If the Trust Fund is liquidated before
completion of a Business Combination, the undersigned agrees to reimburse the
Company for the Company’s Vendor Obligations. 
For purposes of this paragraph, “Vendor Obligations” shall mean
the debts of the Company to vendors from whom the Company does not obtain a
valid and enforceable waiver of such vendor’s rights against or claims to the
Trust Fund for services rendered or products sold to the Company in excess of
the net proceeds of the IPO not held in the Trust Fund at the time of its
liquidation, to the extent that such debts or obligations (i) actually
reduce the amount of funds in the Trust Fund that are distributable to the
Company’s stockholders and (ii) are not reimbursed by any insurance
procured by the Company to cover such claims made against the Trust Fund.  For the avoidance of doubt, Vendor
Obligations do not include (x) any debts or obligations to vendors that do
not represent service fees (and related disbursements) or product purchase
prices, (y) any debts or obligations to prospective target businesses if a
Business Combination is not consummated with such prospective target businesses
or (z) any debts or obligations owed to any entity other than a vendor.

4.             Miscellaneous


 


(a)           The undersigned has full right and
power, without violating any agreement by which the undersigned is bound, to
enter into this letter agreement.


 


(b)           This letter agreement shall be
governed by and construed and enforced in accordance with the laws of the State
of New York, without giving effect to conflicts of law principles that would
result in the application of the substantive laws of another jurisdiction.  The undersigned hereby (i) agrees that
any action, proceeding or claim against him arising out of or relating in any
way to this letter agreement (a “Proceeding”) shall be brought and
enforced in the courts of the State of New York of the United States of America
for the Southern District of New York, and irrevocably submits to such jurisdiction,
which jurisdiction shall be exclusive, and (ii) waives any objection to
such exclusive jurisdiction and that such courts represent an inconvenient
forum.  If for any reason such agent is
unable to act as such, the undersigned will promptly notify the Company and the
Underwriters and appoint a substitute agent acceptable to the Underwriters
within 30 days and nothing in this letter will affect the right of either party
to serve process in any other manner permitted by law.
