                                     WARRANT


     THIS CERTIFIES THAT, for value received _________________________________
is the registered holder of a Warrant or Warrants expiring ________, 2011 [FOUR
YEARS FROM DATE OF PROSPECTUS] ("Warrant") to purchase one fully paid and
non-assessable share of common stock, par value US$.0001 per share ("Shares"),
of Inter-Atlantic Financial, Inc., a Delaware corporation (the "Corporation"),
for each Warrant evidenced by this Warrant Certificate. The Warrant entitles the
holder thereof to purchase from the Corporation, commencing on the later of (i)
its initial business combination with, through a merger, capital stock exchange,
asset acquisition, stock purchase or other similar business combination, one or
more operating businesses (as such business combination is more fully described
in the Company's Registration Statement, No. 333-140690, filed on Form S-1 with
the Securities and Exchange Commission, as amended, for the registration of the
Company's securities or (ii) ______________, 2008, such number of Shares of the
Corporation at the price of US$6.00 per share, upon surrender of this Warrant
Certificate and payment of the Warrant Price at the office or agency of the
Warrant Agent, American Stock Transfer & Trust Company (such payment to be made
by check made payable to the Warrant Agent), but only subject to the conditions
set forth herein and in the Warrant Agreement between the Corporation and
American Stock Transfer & Trust Company. In no event shall the registered holder
of this Warrant be entitled to receive a net-cash settlement, shares of Common
Stock or other consideration in lieu of physical settlement in shares of the
Corporation. The Warrant Agreement provides that upon the occurrence of certain
events the Warrant Price and the number of Warrant Shares purchasable hereunder,
set forth on the face hereof, may, subject to certain conditions, be adjusted.
The term Warrant Price as used in this Warrant Certificate refers to the price
per Share at which Shares may be purchased at the time the Warrant is exercised.


     This Warrant may expire on the date first above written if it is not
exercised prior to such date by the registered holder pursuant to the terms of
the Warrant Agreement or if it is not redeemed by the Corporation prior to such
date.

     No fraction of a Share will be issued upon any exercise of a Warrant. If
the holder of a Warrant would be entitled to receive a fraction of a Share upon
any exercise of a Warrant, the Corporation shall, upon such exercise, round up
to the nearest whole number the number of Shares to be issued to such holder.

     Upon any exercise of the Warrant for less than the total number of full
Shares provided for herein, there shall be issued to the registered holder
hereof or the registered holder's assignee a new Warrant Certificate covering
the number of Shares for which the Warrant has not been exercised.

     Warrant Certificates, when surrendered at the office or agency of the
Warrant Agent by the registered holder hereof in person or by attorney duly
authorized in writing, may be exchanged in the manner and subject to the
limitations provided in the Warrant Agreement, but without payment of any
service charge, for another Warrant Certificate or Warrant Certificates of like
tenor and evidencing in the aggregate a like number of Warrants.

     Upon due presentment for registration of transfer of the Warrant
Certificate at the office or agency of the Warrant Agent, a new Warrant
Certificate or Warrant Certificates of like tenor and evidencing in the
aggregate a like number of Warrants shall be issued to the transferee in
exchange for this Warrant Certificate, subject to the limitations provided in
the Warrant Agreement, without charge except for any applicable tax or other
governmental charge.

     The Corporation and the Warrant Agent may deem and treat the registered
holder as the absolute owner of this Warrant Certificate (notwithstanding any
notation of ownership or other writing hereon made by anyone), for the purpose
of any exercise hereof, of any distribution to the registered holder, and for
all other purposes, and neither the Corporation nor the Warrant Agent shall be
affected by any notice to the contrary.


     Neither this Warrant Certificate nor any of the Warrant(s) evidenced hereby
itself entitles the registered holder to any of the rights of a stockholder of
the Corporation.


     The Corporation reserves the right to call the Warrant at any time prior to
its exercise, with a notice of call in writing to the holders of record of the
Warrant, giving 30 days' notice of such call at any time after the Warrant
becomes exercisable if the last sale price of the Shares has been at least
US$11.50 per share on each of 20 trading days within any 30 trading day period
ending on the third business day prior to the date on which notice of such call
is given. The call price of the Warrants is to be US$.01 per Warrant. Any
Warrant either not exercised or tendered back to the Corporation by the end of
the date specified in the notice of call shall be canceled on the books of the
Corporation and have no further value except for the US$.01 call price.

     This Certificate is not valid unless countersigned by the Warrant Agent
and registered by the Registrar.
