Underwriting Agreement (the "UNDERWRITING AGREEMENT") entered into by and
between Tailwind Financial Inc., a Delaware corporation (the "COMPANY"), and
Deutsche Bank Securities Inc. (the "UNDERWRITER"), relating to an underwritten
initial public offering (the "IPO") of the Company's units (the "UNITS"), each
Unit comprised of one share of the Company's common stock, par value $0.001 per
share (the "COMMON STOCK"), and one warrant, which is exercisable for one share
of Common Stock. Certain capitalized terms used herein are defined in paragraph
11 hereof.

        In order to induce the Company and the Underwriter to enter into the
Underwriting Agreement and to proceed with the IPO, and in recognition 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 and the Underwriter as follows:

1.      If the Company solicits approval of its stockholders of a Business
Combination, the undersigned will vote all Insider Shares owned by him in
accordance with the majority of the votes cast by the holders of the IPO Shares.

2.      In the event that the Company fails to consummate a Business Combination
within eighteen (18) months from the effective date (the "EFFECTIVE DATE") of

undersigned will take all reasonable actions within the undersigned's power to
(i) cause the Trust Account to be liquidated and distributed to the holders of
IPO Shares in accordance with that Investment Management Trust Agreement to be
entered into by and among the Company, Deutsche Bank Securities Inc. and
American Stock Transfer & Trust Company, as Trustee; 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 (x) any
distribution of the Trust Account with respect to the undersigned's Insider
Shares
