WARRANT
      CLARIFICATION AGREEMENT




THIS
      WARRANT CLARIFICATION AGREEMENT (this “ Agreement ”),
      dated


October
      2 ,
      2006,
      is to the Warrant Agreement, dated as of December 17, 2004 (the “ Warrant
      Agreement ”),
      by
      and between MILLSTREAM II ACQUISITION CORPORATION, a Delaware corporation
      (“ Company ”),
      and
      CONTINENTAL STOCK TRANSFER & TRUST COMPANY, a New York corporation
      (“ Warrant
      Agent ”).





WHEREAS,
      Section 3.3.2 of the Warrant Agreement provides that Company shall not be
      obligated to deliver any securities pursuant to the exercise of a Warrant unless
      a registration statement under the Securities Act of 1933, as amended
      (“ Securities
      Act ”),
      with
      respect to the Common Stock is effective;





WHEREAS,
      in furtherance of the foregoing, the Company’s final prospectus, dated December
      17, 2004, indicated (i) that no Warrant would be exercisable unless at the
      time
      of exercise a prospectus relating to the Common Stock issuable upon exercise
      of
      the Warrant is current and the Common Stock has been registered under the
      Securities Act or qualified or deemed to be exempt under the securities laws
      of
      the state of residence of the holder of the Warrant and (ii) that the Warrant
      may be deprived of any value and the market for the Warrant may be limited
      if
      the prospectus relating to the Common Stock issuable upon the exercise of the
      Warrant is not current or if the Common Stock is not qualified or exempt from
      qualification in the jurisdictions in which the holder of the Warrant resides;
      and





WHEREAS,
      as a result of certain questions that have arisen regarding the accounting
      treatment applicable to the Warrants, the parties hereto deem it necessary
      and
      desirable to amend the Warrant Agreement to clarify that the registered holders
      do not have the right to receive a net cash settlement in the event the Company
      does not maintain a current prospectus relating to the Common Stock issuable
      upon exercise of the Warrants at the time such Warrants are
      exercisable.





NOW,
      THEREFORE, in consideration of the mutual agreements contained herein and other
      good and valuable consideration, the receipt and sufficiency of which are hereby
      acknowledged, and intending to be legally bound hereby, the parties hereto
      agree
      to amend the Warrant Agreement as set forth herein.





1.  Warrant
      Agreement .
      The
      Warrant Agreement is hereby amended by adding the following sentence as the
      penultimate sentence of Section 3.3.2 thereof:





“Furthermore,
      if the Company is unable to deliver any securities pursuant to the exercise
      of a
      Warrant as a result of the foregoing situations, the Company will have no
      obligation to pay such registered holder any cash or other consideration or
      otherwise “net cash settle” the Warrant.”





2.  Miscellaneous .





(a)  Defined
      Terms .
      Capitalized terms used but not defined herein shall have the respective meanings
      ascribed to such terms in the Warrant Agreement.












(b)  Governing
      Law .
      The
      validity, interpretation, and performance of this Agreement and of the Warrants
      shall be governed in all respects by the laws of the State of New York, without
      giving effect to conflicts of law principles that would result in the
      application of the substantive laws of another jurisdiction. The Company hereby
      agrees that any action, proceeding or claim against it arising out of or
      relating in any way to this Agreement shall be brought and enforced in the
      courts of the State of New York or the United States District Court for the
      Southern District of New York, and irrevocably submits to such jurisdiction,
      which jurisdiction shall be exclusive. The Company hereby waives any objection
      to such exclusive jurisdiction and that such courts represent an inconvenient
      forum. Any such process or summons to be served upon the Company may be served
      by transmitting a copy thereof by registered or certified mail, return receipt
      requested, postage prepaid, addressed to it at the address set forth in Section
      9.2 of the Warrant Agreement. Such mailing shall be deemed personal service
      and
      shall be legal and binding upon the Company in any action, proceeding or
      claim.





(c)  Binding
      Effect .
      This
      Agreement shall be binding upon and inure to the benefit of the parties hereto
      and to their respective heirs, legal representatives, successors and
      assigns.





(d)  Entire
      Agreement .
      This
      Agreement sets forth the entire agreement and understanding between the parties
      as to the subject matter thereof and merges and supersedes all prior
      discussions, agreements and understandings of any and every nature among them.
      Except as set forth in this Agreement, provisions of the Warrant Agreement
      which
      are not inconsistent with this Agreement shall remain in full force and effect.





(e)  Severability .
      This
      Agreement shall be deemed severable, and the invalidity or unenforceability
      of
      any term or provision hereof shall not affect the validity or enforceability
      of
      this Agreement or of any other term or provision hereof. Furthermore, in lieu
      of
      any such invalid or unenforceable term or provision, the parties hereto intend
      that there shall be added as part of this Agreement a provision as similar
      in
      terms to such invalid or unenforceable provision as may be possible and be
      valid
      and enforceable.





(f)  Execution .
      This
      Agreement may be executed in one or more counterparts, each of which shall
      be
      deemed to be an original, but all of which together shall constitute one and
      the
      same instrument. Each counterpart may be delivered by facsimile transmission,
      which transmission shall be deemed delivery of an originally executed
      document.
