                                EXPLANATORY NOTE

                   POST-EFFECTIVE AMENDMENT NO. 1 TO FORM S-8

     This Post-Effective  Amendment No. 1 to Registration Statement 333-45354 on
Form S-8 is being filed  pursuant to Rule 414 under the  Securities Act of 1933,
as  amended  (the  "Securities   Act"),  to  reflect  the  new  holding  company
organizational structure of Swift Energy Company (the "Registrant"), effected in
accordance  with  Article  5.03.H of the  Texas  Business  Corporation  Act (the
"TBCA") and the  Registrant's  status as the  successor  issuer to Swift  Energy
Company as it was constituted prior to the Merger (as defined below).

     The holding company  organizational  structure was effected  pursuant to an
Plan and Agreement  and Articles of Merger to Form Holding  Company (the "Merger
Agreement")  among  Swift  Energy  Company  as it was  constituted  prior to the
effectuation  of the new holding  company  structure  (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  provides  for the  merger of the  Predecessor  into  Operating,  with
Operating continuing as the surviving entity and as a wholly-owned subsidiary of
the Registrant (the "Merger").  The Merger was effective as of 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.  In connection with the Merger,  the Registrant's  name was changed to
"Swift Energy Company."

     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.

     In accordance with Rule 414, the Registrant, as the successor issuer to the
Predecessor,  hereby  expressly adopts  Registration  Statement No. 333-45354 on
Form S-8 as its own for all purposes under the Securities Act and the Securities
Exchange Act of 1934, as amended.  This Registration  Statement  pertains to the
Swift Energy Company's 1990 Stock  Compensation  Plan, 1990  Nonqualified  Stock
Option Plan and the Employee  Savings Plan,  Registration  fees were paid at the
time of filing the original Registration Statement.
