                 5:00 P.M. NEW YORK CITY TIME, __________, 2008

                      MILLSTREAM II ACQUISITION CORPORATION
                                                                           CUSIP
                                     WARRANT

THIS CERTIFIES THAT, for value received


is the registered holder of a Warrant or Warrants expiring ________, 2008 (the
"Warrant") to purchase one fully paid and non-assessable share of Common Stock,
par value $.0001 per share ("Shares"), of Millstream II Acquisition Corporation,
a Delaware corporation (the "Company"), for each Warrant evidenced by this
Warrant Certificate. The Warrant entitles the holder thereof to purchase from
the Company, commencing on the later of (i) ______________, 2005 or (ii) the
earlier of the Company's completion of a merger, capital stock exchange, asset
acquisition or other similar business combination or the distribution of funds
held by that certain trust account for the benefit of the Company's public
stockholders, such number of Shares of the Company at the price of $5.00 per
share, upon surrender of this Warrant Certificate and payment of the Warrant
Price at the office or agency of the Warrant Agent, Continental 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 Company and Continental Stock Transfer & Trust Company.
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.
     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 Company 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 his 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 Company 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 Company nor the Warrant Agent shall be affected by any
notice to the contrary.
     This Warrant does not entitle the registered holder to any of the rights of
a stockholder of the Company.
     The Company reserves the right to call the Warrant, with the prior consent
of EarlyBirdCapital, Inc., 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 $8.50 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 $.01 per Warrant. Any Warrant either not exercised or tendered back to the
Company by the end of the date specified in the notice of call shall be canceled
on the books of the Company and have no further value except for the $.01 call
price.
