March 9, 2004                                                Warrant to Purchase
                                                          Shares of Common Stock

                       MILLSTREAM ACQUISITION CORPORATION
                             STOCK PURCHASE WARRANT

         THIS CERTIFIES THAT, for value received,  __________, or his registered
assigns,  is entitled to purchase from  Millstream  Acquisition  Corporation,  a
Delaware  corporation (the  "Company"),  at any time or from time to time during
the period  specified in Section 1 hereof,  _____________  (________) fully paid
and  nonassessable  shares of the  Company's  Stock,  no par value (the  "Common
Stock"), at an exercise price of Eight Dollars and Fifty Cents ($8.50) per share
(the  "Exercise  Price"),  subject to  adjustment as provided  herein.  The term
"Warrant  Shares,"  as  used  herein,  refers  to the  shares  of  Common  Stock
purchasable hereunder.

         This  Warrant  is  subject  to the  following  terms,  provisions,  and
conditions:

         1. Period of Exercise.  This Warrant is exercisable at any time or from
time to time  beginning on the date on which the Effective Time of the merger of
N  Merger,   LLC,  the  Company's   wholly-owned   subsidiary,   with  and  into
NationsHealth Holdings, L.L.C. occurs (the "Effective Date"), as defined in that
certain  Agreement  and Plan of  Merger  dated as of March 9,  2004,  among  the
Company,  N  Merger,  LLC  and  NationsHealth  Holdings,   L.L.C.  (the  "Merger
Agreement"),  and  ending  at 5:00  p.m.,  New  York  City  time on the  seventh
anniversary of the Effective Date (the "Exercise Period"). In the event that the
Merger  Agreement is terminated in  accordance  with Article VIII thereof,  then
this Warrant shall automatically terminate and be deemed null and void.

         2. Manner of Exercise; Issuance of Certificates; Payment for Shares.

            (a) Subject to the provisions hereof,  this Warrant may be exercised
by the holder  hereof,  in whole or in part,  by the  surrender of this Warrant,
together with a completed  exercise  agreement in the form attached  hereto (the
"Exercise  Agreement"),  to the  Company  during  normal  business  hours on any
business day during the Exercise  Period at the  Company's  principal  executive
offices (or such other  office or agency of the Company as it may  designate  by
notice to the  holder  hereof),  and upon  payment to the  Company  in cash,  by
certified  or  official  bank check or by wire  transfer  for the account of the
Company of the Exercise Price for the Warrant  Shares  specified in the Exercise
Agreement.  The Warrant Shares so purchased  shall be deemed to be issued to the
holder hereof or such holder's designee,  as the record owner of such shares, as
of the close of  business  on the date on which  this  Warrant  shall  have been
surrendered,  the completed  Exercise  Agreement  shall have been  delivered and



<PAGE>

payment  shall  have  been  made for such  shares  (or an  election  to effect a
cashless  exercise  pursuant to Section  2(b) has been made) as set forth above.
Certificates  for the Warrant  Shares so purchased,  representing  the aggregate
number of shares specified in the Exercise Agreement,  shall be delivered to the
holder  hereof within three (3) business days after this Warrant shall have been
so exercised.  The  certificates so delivered shall be in such  denominations as
may be requested  by the holder  hereof and shall be  registered  in the name of
such holder or such other name as shall be  designated  by such holder.  If this
Warrant shall have been  exercised only in part,  then,  unless this Warrant has
expired,  the Company  shall,  at its  expense,  at the time of delivery of such
certificates,  deliver to the holder a new  Warrant  representing  the number of
shares with respect to which this Warrant shall not then have been exercised.

     (b) Net Issue  Exercise.  In lieu of  exercising  any  Warrant  pursuant to
Section  2(a),  the  registered  holder  thereof may elect to receive  shares of
Common Stock (the "Net Issue  Right") by surrender of the Warrant to the Company
with the Exercise  Agreement duly  executed,  electing to exercise its Net Issue
Right pursuant to this Section 2(b).  Upon election of the Net Issue Right,  the
registered  holder  shall be entitled  to that number of shares of Common  Stock
(without  payment  by the  holder  of any  Exercise  Price)  computed  using the
following formula:

                           X = Y(W-Z)
                               ------
                                 W

                  Where:

                    X    = the number of shares of Common  Stock to be issued to
                         the registered holder;
                    Y    = the  number of shares  of  Common  Stock  purchasable
                         under the Warrant (at the date of such calculation);
                    W    = the  fair  market  value of one  share of the  Common
                         Stock (at the date of such calculation);
                    Z    = the  Exercise  Price (as  adjusted  according  to the
                         terms set forth herein).

As used in this Section  2(b),  "fair market value" of one share of Common Stock
shall mean the  average  closing  price,  for the ten trading  days  immediately
preceding the date the Exercise Agreement is submitted to the Company, per share
of Common Stock as reported on the Nasdaq Stock Market (the  "NASDAQ"),  the New
York Stock Exchange (the "NYSE"),  the American Stock Exchange (the "AMEX"), any
other stock exchange or the over-the-counter market, as applicable,  as reported
in The Wall  Street  Journal  (Northeast  edition),  or,  if not  then  reported
thereby,  any other  authoritative  source. If the Common Stock is not traded on
the NASDAQ, the NYSE, the AMEX, any other stock exchange or the over-the-counter
market,  then in lieu of the average  closing  price,  fair market  value of the
Common  Stock per share shall be the price per share that is  determined  by the
Board of  Directors of the Company  acting  reasonably  and in good faith.  Upon
exercise of its Net Issue Right pursuant to this Section 2(b) and the receipt by
the registered  holder of the applicable shares of Common Stock, the obligations
of the  Company to  deliver  shares of Common  Stock  shall be  terminated  with
respect to the number of shares of Common Stock for which the registered  holder
shall have exercised its Net Issue Right.

                                      -2-
<PAGE>

         3. Certain Agreements of the Company.  The Company hereby covenants and
agrees as follows:

            (a) Shares to be Fully Paid. All Warrant Shares will,  upon issuance
in accordance with the terms of this Warrant, be validly issued, fully paid, and
nonassessable  and free from all taxes,  liens,  and charges with respect to the
issue thereof.

            (b) Reservation of Shares.  During the Exercise Period,  the Company
shall at all times have  authorized,  and  reserved  for the purpose of issuance
upon exercise of this Warrant,  a sufficient number of shares of Common Stock to
provide for the exercise in full of this Warrant.

            (c) Certain Actions  Prohibited.  The Company will not, by amendment
of its charter or through any reorganization, transfer of assets, consolidation,
merger, dissolution, issue or sale of securities, or any other voluntary action,
avoid or seek to avoid the  observance or  performance of any of the terms to be
observed  or  performed  by it  hereunder,  but will at all times in good  faith
assist in the  carrying  out of all the  provisions  of this  Warrant and in the
taking of all such action as may  reasonably  be requested by the holder of this
Warrant in order to protect the exercise privilege of the holder of this Warrant
against dilution or other  impairment,  consistent with the tenor and purpose of
this Warrant.  Without limiting the generality of the foregoing, the Company (i)
will not increase the par value of any shares of Common Stock  issuable upon the
exercise of this Warrant above the Exercise Price then in effect,  and (ii) will
take all such  actions  as may be  necessary  or  appropriate  in order that the
Company may validly and  legally  issue fully paid and  nonassessable  shares of
Common Stock upon the exercise of this Warrant.

            (d)  Successors  and Assigns.  This Warrant will be binding upon any
entity succeeding to the Company by merger, consolidation, or acquisition of all
or substantially all the Company's assets.

         4. Adjustments.

            (a) Stock  Dividends  -  Split-Ups.  If after the date  hereof,  and
subject to the  provisions  of Section  4(f)  below,  the number of  outstanding
shares of Common  Stock is increased  by a stock  dividend  payable in shares of
Common  Stock,  or by a split-up  of shares of Common  Stock,  or other  similar
event,  then, on the effective date of such stock dividend,  split-up or similar
event, the number of shares of Common Stock issuable on exercise of each Warrant
shall be increased in proportion to such increase in outstanding shares.

            (b) Aggregation of Shares. If after the date hereof,  and subject to
the provisions of Section 4(f), the number of outstanding shares of Common Stock
is  decreased  by  a   consolidation,   combination,   reverse  stock  split  or
reclassification  of shares of Common Stock or other similar event, then, on the
effective  date  of  such  consolidation,   combination,  reverse  stock  split,
reclassification or similar event, the number of shares of Common Stock issuable
on exercise of each Warrant shall be decreased in proportion to such decrease in
outstanding shares.

            (c) Adjustments in Exercise Price.  Whenever the number of shares of
Common Stock  purchasable  upon the  exercise of the  Warrants is  adjusted,  as
provided in Section 4(a) or 4(b) above, the Exercise Price shall be adjusted (to
the nearest cent) by multiplying such Exercise Price  immediately  prior to such
adjustment  by a  fraction  (x) the  numerator  of which  shall be the number of





                                      -3-
<PAGE>

shares of Common Stock purchasable upon the exercise of the Warrants immediately
prior to such  adjustment,  and (y) the denominator of which shall be the number
of shares of Common Stock so purchasable immediately thereafter.

            (d) Replacement of Securities upon  Reorganization,  etc. In case of
any reclassification or reorganization of the outstanding shares of Common Stock
(other  than a change  covered by  Section  4(a) or 4(b)  hereof or that  solely
affects  the par value of such  shares of Common  Stock),  or in the case of any
merger or consolidation of the Company with or into another  corporation  (other
than  a  consolidation  or  merger  in  which  the  Company  is  the  continuing
corporation and that does not result in any  reclassification  or reorganization
of the  outstanding  shares  of  Common  Stock),  or in the  case of any sale or
conveyance to another corporation or entity of the property of the Company as an
entirety or substantially as an entirety in connection with which the Company is
dissolved,  the Warrant holders shall  thereafter have the right to purchase and
receive,  upon the  basis and upon the terms  and  conditions  specified  in the
Warrants  and in lieu of the shares of Common  Stock of the Company  immediately
theretofore   purchasable  and  receivable  upon  the  exercise  of  the  rights
represented  thereby, the kind and amount of shares of stock or other securities
or   property   (including   cash)   receivable   upon  such   reclassification,
reorganization,  merger or  consolidation,  or upon a dissolution  following any
such sale or  transfer,  by a Warrant  holder of the  number of shares of Common
Stock of the Company obtainable upon exercise of the Warrants  immediately prior
to such event; and if any reclassification also results in a change in shares of
Common Stock covered by Section 4(a) or 4(b), then such adjustment shall be made
pursuant to Sections 4(a),  4(b),  4(c) and this Section 4(d). The provisions of
this  Section  4(d)  shall  similarly  apply  to  successive  reclassifications,
reorganizations, mergers or consolidations, sales or other transfers.

            (e)  Notices of Changes in  Warrant.  Upon every  adjustment  of the
Exercise  Price or the number of shares  issuable on exercise of a Warrant,  the
Company shall give written  notice thereof to the Warrant  holder,  which notice
shall state the Exercise Price  resulting from such  adjustment and the increase
or decrease,  if any, in the number of shares purchasable at such price upon the
exercise  of a  Warrant,  setting  forth in  reasonable  detail  the  method  of
calculation  and the facts  upon  which  such  calculation  is  based.  Upon the
occurrence of any event specified in Sections 4(a), 4(b), 4(c) or 4(d), then, in
any such event,  the Company shall give written  notice to the Warrant holder of
the record date or the effective date of the event. Failure to give such notice,
or any defect therein, shall not affect the legality or validity of such event.

            (f) No Fractional Shares. Notwithstanding any provision contained in
this Agreement to the contrary,  the Company shall not issue  fractional  shares
upon exercise of Warrants. If, by reason of any adjustment made pursuant to this
Section 4, the holder of any Warrant  would be  entitled,  upon the  exercise of
such Warrant,  to receive a fractional  interest in a share,  the Company shall,
upon such  exercise,  round up to the nearest  whole  number,  the number of the
shares of Common Stock to be issued to the Warrant holder.

            (g) Form of Warrant. The form of Warrant need not be changed because
of any  adjustment  pursuant to this Section 4, and  Warrants  issued after such
adjustment may state the same Exercise Price and the same number of shares as is
stated in the Warrants initially issued pursuant to this Agreement. However, the
Company  may at any time in its sole  discretion  make any change in the form of
Warrant  that the  Company  may deem  appropriate  and that does not  affect the
substance thereof,  and any Warrant thereafter issued or countersigned,  whether





                                      -4-
<PAGE>

in exchange or substitution for an outstanding  Warrant or otherwise,  may be in
the form as so changed.

         5. Issue Tax. The issuance of certificates  for Warrant Shares upon the
exercise  of this  Warrant  shall be made  without  charge to the holder of this
Warrant or such shares for any issuance tax or other costs in respect thereof.

         6. No Rights or Liabilities  as a  Shareholder.  This Warrant shall not
entitle the holder  hereof to any voting rights or other rights as a shareholder
of the  Company.  No provision of this  Warrant,  in the absence of  affirmative
action by the holder hereof to purchase Warrant Shares,  and no mere enumeration
herein of the rights or privileges of the holder hereof,  shall give rise to any
liability  of such  holder for the  Exercise  Price or as a  shareholder  of the
Company,  whether  such  liability is asserted by the Company or by creditors of
the Company.

         7. Transfer, Exchange, and Replacement of Warrant.

            (a) Restriction on Transfer.  This Warrant and the rights granted to
the holder hereof are transferable,  in whole or in part, upon surrender of this
Warrant,  together  with a properly  executed  assignment  in the form  attached
hereto,  at the office or agency of the  Company  referred  to in  Section  7(e)
below;  provided,  however,  that any transfer or assignment shall be subject to
the conditions set forth in Section 7(f).

            (b) Warrant Exchangeable for Different  Denominations.  This Warrant
is exchangeable, upon the surrender hereof by the holder hereof at the office or
agency of the Company  referred to in Section  7(e) below,  for new  Warrants of
like tenor  representing  in the  aggregate  the right to purchase the number of
shares  of  Common  Stock  which may be  purchased  hereunder,  each of such new
Warrants to  represent  the right to purchase  such number of shares as shall be
designated by the holder hereof at the time of such surrender.

            (c)  Replacement  of Warrant.  Upon receipt of evidence of the loss,
theft,  destruction,  or mutilation of this Warrant and, in the case of any such
loss, theft, or destruction,  upon delivery of an indemnity agreement reasonably
satisfactory  in form and  amount  to the  Company,  or, in the case of any such
mutilation, upon surrender and cancellation of this Warrant, the Company, at its
expense, will execute and deliver, in lieu thereof, a new Warrant of like tenor.

            (d)  Cancellation;  Payment of Expenses.  Upon the surrender of this
Warrant in connection with any transfer, exchange, or replacement as provided in
this Section 7, this  Warrant  shall be promptly  canceled by the  Company.  The
Company shall pay all taxes (other than securities transfer taxes) and all other
expenses  (other  than  legal  expenses,  if  any,  incurred  by the  holder  or
transferees) and charges payable in connection with the preparation,  execution,
and delivery of Warrants pursuant to this Section 7.

            (e) Register. The Company shall maintain, at its principal executive
offices (or such other  office or agency of the Company as it may  designate  by
notice to the holder hereof), a register for this Warrant,  in which the Company
shall  record the name and address of the person in whose name this  Warrant has
been issued,  as well as the name and address of each  transferee and each prior
owner of this Warrant.

<PAGE>

            (f) Exercise or Transfer  Without  Registration.  If, at the time of
the surrender of this Warrant in  connection  with any  exercise,  transfer,  or
exchange of this  Warrant,  this Warrant (or, in the case of any  exercise,  the
Warrant Shares issuable hereunder), shall not be registered under the Securities
Act and under  applicable  state  securities  or blue sky laws,  the Company may
require, as a condition of allowing such exercise,  transfer, or exchange,  that
the holder or  transferee of this  Warrant,  as the case may be,  furnish to the
Company a written opinion of counsel to the effect that such exercise, transfer,
or exchange may be made without  registration under the Securities Act and under
applicable state securities or blue sky laws;  provided  however,  that no legal
opinion  shall be required in  connection  with a transfer  pursuant to Rule 144
under the Securities Act.

         8. Notices.  Any notice which is required or provided to be given under
this Warrant  shall be deemed to have been  sufficiently  given and received for
all  purposes  when  delivered by hand,  telecopy  (if a copy of such  confirmed
telecopy  transmission shall be contemporaneously  sent by first class mail), or
