                                EXPLANATORY NOTE

                   POST EFFECTIVE AMENDMENT NO. 2 TO FORM S-3

     Swift  Energy  Company,  a Texas  corporation,  formerly  New Swift  Energy
Company (the  "Registrant"),  was organized to enable its predecessor,  formerly
Swift Energy Company,  a Texas corporation  ("Predecessor"),  to adopt a holding
company organizational  structure in accordance with Article 5.03.H of the Texas
Business  Corporation  Act (the  "TBCA").  In  accordance  with  Rule  414,  the
Registrant,  as the successor  issuer to the  Predecessor in the holding company
reorganization  described  below, is filing this Amendment No. 2 to Registration
Statement  No.  333-112041  in  order to  hereby  expressly  adopt  Registration
Statement  No.  333-112041  on Form S-3 as its own for all  purposes  under  the
Securities Act and the Securities Exchange Act of 1934, as amended. Registration
fees were paid at the time of filing the original Registration Statement.

     The purposes for creating  the holding  company  structure  are to create a
classical  holding  company,   separate  Swift  Energy  Company's  domestic  and
international  operations to more closely reflect its management structure,  and
provide for a more equitable allocation of state taxes.

     The holding  company  organizational  structure was effected  pursuant to a
Plan and  Agreement  and Articles of Merger (the "Merger  Agreement")  among the
Predecessor,  the Registrant,  and Swift Energy Operating,  LLC, a Texas limited
liability company and a wholly owned subsidiary of the Registrant ("Operating").
The Merger Agreement  provided for the merger of the Predecessor into Operating,
with Operating  continuing as the surviving entity and a wholly owned subsidiary
of the  Registrant  (the  "Merger").  The Merger became  effective at 9:00 a.m.,
local time in Austin,  Texas on December  28,  2005.  Prior to the  Merger,  the
Registrant was a direct,  wholly owned  subsidiary of the Predecessor  organized
for the purpose of implementing  the holding company  organizational  structure.
Pursuant to Article 5.03.H of the TBCA,  shareholder  approval of the Merger was
not  required.  The  reorganization  was  structured  so that it is  tax-free to
Swift's shareholders.

     By virtue of the Merger, all of the Predecessor's outstanding capital stock
was converted, on a share for share basis, into capital stock of the Registrant.
As a  result,  each  shareholder  of the  Predecessor  became  the  owner  of an
identical  number of shares of capital  stock of the  Registrant.  Additionally,
each  treasury  share of the  Predecessor  was  automatically  converted  into a
treasury share of the  Registrant.  Also,  each  outstanding  option to purchase
shares of the  Predecessor's  common stock was  automatically  converted into an
option to purchase,  upon the same terms and conditions,  an identical number of
shares of the Registrant's common stock.  Finally, each preferred share purchase
right  under  the  Predecessor's  Amended  and  Restated  Rights  Agreement  was
automatically  converted,  upon the same terms and conditions,  into a preferred
share purchase right for each outstanding share of the Registrant's common stock
held by such holder.

     Under the TBCA,  the  conversion of shares of stock in the Merger  occurred
without  an  exchange  of  certificates.   Accordingly,   certificates  formerly
representing  shares  of  outstanding  stock of the  Predecessor  are  deemed to
represent the same number of shares of stock of the Registrant. The Registrant's
CUSIP  number  will  remain the same and the common  stock will  continue  to be
listed  on  the  New  York  Stock   Exchange  under  the  symbol  "SFY"  without
interruption  and the  Registrant  will  use the same  name as the  Predecessor,
"Swift Energy Company."

     In the Merger,  each  shareholder  received  securities  of the same class,
evidencing the same proportional interests in the Registrant and having the same
designations,  rights, powers and preferences,  and qualifications,  limitations
and  restrictions,  as  those  that  the  shareholder  held in the  Predecessor.



                                      -2-


Pursuant  to Article  5.03.H of the TBCA,  the  articles of  incorporation,  the
certificate of designation and the bylaws of the Registrant  contain  provisions
substantially  identical to those of the Predecessor  prior to the Merger.  Also
pursuant  to  Article  5.03.H of the  TBCA,  the  regulations  and  articles  of
organization of Operating  contain a provision that any act or transaction by or
involving  Operating,  other  than  the  election  or  removal  of  managers  of
Operating,  that  requires  for  its  adoption  under  Operating's  articles  of
organization or regulations  the approval of the members of Operating,  or would
require the  approval of the  shareholders  of  Operating  if  Operating  were a
corporation  subject to the Texas Business  Corporation  Act, shall in addition,
require approval of the shareholders of the Registrant and as further  specified
in the  organizational  documents of Operating.  The authorized capital stock of
the Registrant, the designations, rights, powers and preferences of such capital
stock and the  qualifications,  limitations  and  restrictions  thereof are also
substantially  identical to those of the Predecessor's capital stock immediately
prior to the Merger.  The directors and executive officers of the Registrant are
the same individuals who were directors and executive officers, respectively, of
the Predecessor immediately prior to the Merger.
