                                    EXHIBIT A

                           SECOND AMENDED AND RESTATED
                         CERTIFICATE OF INCORPORATION OF
                             TAILWIND FINANCIAL INC.

     FIRST: The name of the corporation is Tailwind Financial Inc. (the
"CORPORATION").

     SECOND: The registered office of the Corporation is to be located at
2711 Centerville Road Suite 400, in the City of Wilmington, County of New
Castle, 19808. The name of its registered agent at that address is Corporation
Service Company.

     THIRD: Subject to the immediately succeeding sentence and Article Fifth,
the purpose of the Corporation shall be to engage in any lawful act or activity
for which corporations may be organized under the General Corporation Law of the
State of Delaware ("GCL"). In addition to the powers and privileges conferred
upon the Corporation by law and those incidental thereto, the Corporation shall
possess and may exercise all the powers and privileges which are necessary or
convenient to the conduct, promotion or attainment of the business or purposes
of the Corporation; provided, however, that in the event a Business Combination
(as defined below) is not consummated prior to the Initial Termination Date (as
defined below), then the purposes of the Corporation shall automatically, with
no action required by the board of directors (the "BOARD") or the stockholders,
on the Initial Termination Date be limited to effecting and implementing the
dissolution and liquidation of the Corporation and the taking of any other
actions expressly required to be taken herein on or after the Initial
Termination Date and the Corporation's powers shall thereupon be limited to
those set forth in Section 278 of the GCL and as otherwise may be necessary to
implement the limited purposes of the Corporation as provided herein. This
Article Third may not be amended without the affirmative vote of at least 95% of
the IPO Shares (as defined below) cast at a meeting of stockholders of the
Corporation.

     FOURTH: The total number of shares of all classes of capital stock which
the Corporation shall have authority to issue is 75,000,000 of which 70,000,000
shares shall be common stock of the par value of $.001 per share ("COMMON
STOCK") and 5,000,000 shares shall be preferred stock of the par value of $.01
per share ("PREFERRED STOCK").

          (A)  PREFERRED STOCK. The Board is expressly granted authority to
issue shares of the Preferred Stock, in one or more series, and to fix for each
such series such voting powers, full or limited, and such designations,
preferences and relative, participating, optional or other special rights and
such qualifications, limitations or restrictions thereof as shall be stated and
expressed in the resolution or resolutions adopted by the Board providing for
the issue of such series (a "PREFERRED STOCK DESIGNATION") and as may be
permitted by the GCL. The number of authorized shares of Preferred Stock may be
increased or decreased (but not below the number of shares thereof then
outstanding) by the affirmative vote of the holders of a majority of the voting
power of all of the then outstanding shares of the capital stock of the
Corporation entitled to vote generally in the election of directors, voting
together as a single class, without a separate vote of the holders of the
Preferred Stock, or any series thereof, unless a vote of any such holders is
required pursuant to any Preferred Stock Designation.

          (B)  COMMON STOCK. Except as otherwise required by law or as otherwise
provided in any Preferred Stock Designation, the holders of the Common Stock
shall exclusively possess all voting power and each share of Common Stock shall
have one vote.

     FIFTH: The Corporation's existence shall terminate on April 17, 2009
(the "Termination Date"). This provision may only be amended in connection
with, and become effective upon, the consummation of a Business Combination
(defined below). A proposal to so amend this section shall be submitted to
stockholders in connection with any proposed Business Combination pursuant to
Article Sixth (B) below.

     SIXTH: The following provisions (A) through (G) shall apply during the
period commencing upon the filing of this Second Amended and Restated
Certificate of Incorporation and shall terminate upon the consummation of

<Page>

any Business Combination (as defined below), and may not be amended during the
Target Business Acquisition Period (as defined below) without the affirmative
vote of at least 95% of the IPO Shares (as defined below) cast at a meeting of
stockholders of the Corporation. A "BUSINESS COMBINATION" shall mean the
acquisition by the Corporation, whether by merger, capital stock exchange,
exchangeable share transaction, asset or stock acquisition or other similar type
of transaction, of an operating business or businesses having collectively, a
fair market value (as calculated in accordance with the requirements set forth
below) of at least 80% of the Corporation's net assets at the time of the
acquisition, PROVIDED, however, that any acquisition of multiple operating
businesses shall occur contemporaneously with one another ("TARGET BUSINESS").
The "TARGET BUSINESS ACQUISITION PERIOD" shall mean the period from the
effectiveness of the registration statement filed in connection with the
Corporation's initial public offering of securities ("IPO") up to and including
the first to occur of (a) a Business Combination, (b) the Initial Termination
Date or (c) the Termination Date (as defined below). For purposes of this
Article, fair market value shall be determined by the Board based upon standards
generally accepted by the financial community, such as actual and potential
sales, earnings and cash flow, and book value. If the Board is not able to
independently determine that the Target Business has a sufficient fair market
value, or if a conflict of interest exists, the Corporation will obtain an
opinion from an unaffiliated, independent investment banking firm with respect
to the satisfaction of such criteria.

          (A)  Immediately after the IPO, the amount of the net offering
proceeds received by the Corporation in the IPO (including the proceeds of any
exercise of the underwriter's over-allotment option) specified in the
Corporation's registration statement on Form S-1 filed with the Securities and
Exchange Commission (the "REGISTRATION STATEMENT") at the time it goes effective
shall be deposited and thereafter held in a trust account established by the
Corporation (the "TRUST ACCOUNT"). Neither the Corporation nor any officer,
director or employee of the Corporation shall disburse any of the proceeds held
in the Trust Account until the earlier of (i) a Business Combination or (ii) the
liquidation of the Corporation as discussed in Paragraph (D) below, in each case
in accordance with the terms of the investment management trust agreement
governing the Trust Account; PROVIDED, HOWEVER, that prior to such date, the
Corporation shall be entitled to withdraw (x) up to $1,600,000 of interest
earned on the Trust Account (net of income taxes payable on this amount) to
fund a portion of the Corporation's working capital expenses, and (y) such
amounts from the Trust Account as would be required to pay taxes on the
interest earned on the Trust Account.

          (B)  Prior to the consummation of any Business Combination, the
Corporation shall submit such Business Combination to its stockholders for
approval regardless of whether the Business Combination is of a type which
normally would require such stockholder approval under the GCL. In the event
that a majority of the shares cast at the meeting to approve the Business
Combination are voted for the approval of such Business Combination, the
Corporation shall be authorized to consummate the Business Combination; provided
that the Corporation shall not consummate any Business Combination if the
holders of 20% or more of the IPO Shares (as defined below) exercise their
conversion rights described in Paragraph (C) below.

          (C)  In the event that a Business Combination is approved in
accordance with the above Paragraph (B) and is consummated by the Corporation,
any stockholder of the Corporation holding shares of Common Stock issued in the
IPO (the "IPO SHARES") who voted against the Business Combination may,
contemporaneous with such vote, demand that the Corporation convert his, her or
its IPO Shares into cash. If so demanded, the Corporation shall, promptly after
consummation of the Business Combination, convert such shares into cash at a per
share conversion price equal to (i) the amount held in the Trust Account (net of
taxes payable), including a pro rata portion of the underwriters' deferred
compensation (calculated as of two business days prior to the consummation of
the Business Combination), divided by (ii) the total number of IPO Shares.

          (D)  In the event that the Corporation does not execute a letter of
intent, an agreement in principle or a definitive agreement to complete a
Business Combination within 18 months after the consummation of the IPO (the
"INITIAL TERMINATION DATE"), the directors and officers of the Corporation shall
take all such action necessary to dissolve the Corporation and liquidate the
Trust Account to holders of IPO Shares as soon as reasonably practicable, and
after approval of the Corporation's stockholders and subject to the requirements
of the GCL, including the adoption of a resolution by the Board, prior to such
Initial Termination Date, pursuant to Section 275(a) of the GCL, in which the
Board finds the dissolution of the Corporation advisable and providing such
notices as are required by said Section 275(a) of the GCL as promptly thereafter
as possible. In the event that (i) the stockholders vote in favor of such
dissolution and the Corporation is so dissolved or (ii) the Corportion's
existence terminates on the Termination Date, the Corporation shall promptly
adopt and implement a plan of distribution

                                       3
<Page>

which provides that only the holders of IPO Shares shall be entitled to share
ratably in the Trust Fund plus any other net assets of the Corporation not used
for or reserved to pay obligations and claims or such other corporate expenses
relating to or arising during the Corporation's remaining existence, including
costs of dissolving and liquidating the Corporation. The Corporation shall pay
no liquidating distributions with respect to any shares of capital stock of the
Corporation other than IPO Shares.

          (E)  A holder of IPO Shares shall be entitled to receive funds from
the Trust Account only (i) in the event of a liquidation of the Trust Account to
holders of IPO Shares in connection with (a) the dissolution of the Corporation
or (b) the termination of the Corportion's existence on the Termination Date,
pursuant to the terms of the investment management trust agreement governing the
Trust Account or (ii) in the event he, she or it demands conversion of such IPO
Shares in accordance with Paragraph (B), above. In no other circumstances shall
a holder of IPO Shares have any right or interest of any kind in or to the Trust
Account. A holder of shares issued in a private placement concurrently with or
prior to the consummation of the IPO shall not have any right or interest of any
kind in or to the Trust Account.

          (F)  Unless and until the Corporation has consummated a Business
Combination as permitted under this Article Sixth, the Corporation may not
consummate any other business combination, whether by merger, capital stock
exchange, stock purchase, asset acquisition, exchangeable share transaction or
otherwise.

          (G)  The Board shall be divided into three classes: Class I, Class II
and Class III. The number of directors in each class shall be as nearly equal as
possible. At the first election of directors by the incorporator, the
incorporator shall elect a Class III director for a term expiring at the
Corporation's third annual meeting of stockholders. The Class III director shall
then appoint additional Class I, Class II and Class III directors, as necessary.
The directors in Class I shall be elected for a term expiring at the first
annual meeting of stockholders following the IPO, the directors in Class II
shall be elected for a term expiring at the second annual meeting of
stockholders following the IPO and the directors in Class III shall be elected
for a term expiring at the third annual meeting of stockholders following the
IPO. Commencing at the first annual meeting of stockholders, and at each annual
meeting thereafter, directors elected to succeed those directors whose terms
expire shall be elected for a term of office to expire at the third succeeding
annual meeting of stockholders after their election. Except as the GCL may
otherwise require, in the interim between annual meetings of stockholders or
special meetings of stockholders called for the election of directors and/or the
removal of one or more directors and the filling of any vacancy in that
connection, newly created directorships and any vacancies in the Board,
including unfilled vacancies resulting from the removal of directors for cause,
may be filled by the vote of a majority of the remaining directors then in
office, although less than a quorum (as defined in the Corporation's Bylaws), or
by the sole remaining director. All directors shall hold office until the
expiration of their respective terms of office and until their successors shall
have been elected and qualified. A director elected to fill a vacancy resulting
from the death, resignation or removal of a director shall serve for the
remainder of the full term of the director whose death, resignation or removal
shall have created such vacancy and until his or her successor shall have been
elected and qualified.

     SEVENTH: The following provisions are inserted for the management of the
business and for the conduct of the affairs of the Corporation, and for further
definition, limitation and regulation of the powers of the Corporation and of
its directors and stockholders:

          (A)  Election of directors need not be by ballot unless the by-laws of
the Corporation so provide.

          (B)  The Board shall have the power, without the assent or vote of the
stockholders, to make, alter, amend, change, add to or repeal the by-laws of the
Corporation as provided in the by-laws of the Corporation.

          (C)  The directors in their discretion may submit any contract or act
for approval or ratification at any annual meeting of stockholders or at any
special meeting of stockholders called for the purpose of considering any such
act or contract, and any contract or act that shall be approved or be ratified
by the vote of the holders of a majority of the stock of the Corporation which
is represented in person or by proxy at such meeting and entitled to vote
thereat (provided that a lawful quorum of stockholders be there represented in
person or by proxy)

                                       4
<Page>

shall be as valid and binding upon the Corporation and upon all the stockholders
as though it had been approved or ratified by every stockholder of the
Corporation, whether or not the contract or act would otherwise be open to legal
attack because of directors' interests, or for any other reason.

          (D)  In addition to the powers and authorities hereinbefore or by
statute expressly conferred upon them, the directors are hereby empowered to
exercise all such powers and do all such acts and things as may be exercised or
done by the Corporation; subject, nevertheless, to the provisions of the
statutes of Delaware, of this Second Amended and Restated Certificate of
Incorporation, and to any by-laws from time to time made by the stockholders;
provided, however, that no by-law so made shall invalidate any prior act of
the directors which would have been valid if such by-law had not been made.

     EIGHTH:

          (A)  A director of the Corporation shall not be personally liable to
the Corporation or its stockholders for monetary damages for breach of fiduciary
duty as a director, except for liability (i) for any breach of the director's
duty of loyalty to the Corporation or its stockholders, (ii) for acts or
omissions not in good faith or which involve intentional misconduct or a knowing
violation of law, (iii) under Section 174 of the GCL, or (iv) for any
transaction from which the director derived an improper personal benefit. If the
GCL is amended to authorize corporate action further eliminating or limiting the
personal liability of directors, then the liability of a director of the
Corporation shall be eliminated or limited to the fullest extent permitted by
the GCL, as so amended. Any repeal or modification of this Paragraph (A) by the
stockholders of the Corporation shall not adversely affect any right or
protection of a director of the Corporation with respect to events occurring
prior to the time of such repeal or modification.

          (B)  The Corporation, to the full extent permitted by Section 145 of
the GCL, as amended from time to time, shall indemnify all persons whom it may
indemnify pursuant thereto. Expenses (including attorneys' fees) incurred by an
officer or director in defending any civil, criminal, administrative, or
investigative action, suit or proceeding for which such officer or director may
be entitled to indemnification hereunder shall be paid by the Corporation in
advance of the final disposition of such action, suit or proceeding upon receipt
of an undertaking by or on behalf of such director or officer to repay such
amount if it shall ultimately be determined that he is not entitled to be
indemnified by the Corporation as authorized hereby.

     NINTH: Whenever a compromise or arrangement is proposed between this
Corporation and its creditors or any class of them and/or between this
Corporation and its stockholders or any class of them, any court of equitable
jurisdiction within the State of Delaware may, on the application in a summary
way of this Corporation or of any creditor or stockholder thereof or on the
application of any receiver or receivers appointed for this Corporation under
Section 291 of Title 8 of the GCL or on the application of trustees in
dissolution or of any receiver or receivers appointed for this Corporation under
Section 279 of Title 8 of the GCL order a meeting of the creditors or class of
creditors, and/or of the stockholders or class of stockholders of this
Corporation, as the case may be, to be summoned in such manner as the said court
directs. If a majority in number representing three fourths in value of the
creditors or class of creditors, and/or of the stockholders or class of
stockholders of this Corporation, as the case may be, agree to any compromise or
arrangement and to any reorganization of this Corporation as a consequence of
such compromise or arrangement, the said compromise or arrangement and the said
reorganization shall, if sanctioned by the court to which the said application
has been made, be binding on all the creditors or class of creditors, and/or on
all the stockholders or class of stockholders, of this Corporation, as the case
may be, and also on this Corporation.

                                       5
