Ladies and Gentlemen:

     In  connection  with the filing of the  Registration  Statement on Form S-4
(the  "Registration  Statement"),  you have asked us to address the  anticipated
material U.S. federal income tax consequences of the exchange of Euro 90,000,000
8 7/8%  Senior  Secured  Notes due 2009  issued on  November  26, 2004 (the "Old
Notes") for new notes (the "New Notes")  that are  identical to the Old Notes in
all material  respects except that they (i) are registered  under the Securities
Act of 1933, as amended (the  "Securities  Act"),  (ii) will not contain certain
transfer  restrictions and  registration  rights of the Old Notes and (iii) will
not contain provisions relating to the payment of additional interest to holders
of the Old Notes  under  circumstances  relating  to the  timing of an  exchange
offer.  More  particularly,   you  have  requested  our  opinion  regarding  the
anticipated  material U.S.  federal  income tax  consequences  under the heading
"Certain  Tax  Considerations  -  United  States  Tax   Considerations"  in  the
Registration Statement filed on the date hereof with the Securities and Exchange
Commission  (the  "Commission")  under  the  Securities  Act.  This  opinion  is
delivered in accordance  with the  requirements  of Item 601(b)(8) of Regulation
S-K under the Securities Act.

     In rendering our opinion,  we have reviewed the Registration  Statement and
such other  materials as we have deemed  necessary or appropriate as a basis for
our opinion.  In addition,  we have considered the applicable  provisions of the
Internal  Revenue Code of 1986,  as amended (the "Code"),  Treasury  regulations
promulgated  thereunder by the U. S. Department of Treasury (the "Regulations"),
pertinent  judicial  authorities,  rulings of the Internal  Revenue Service (the
"IRS") and such other authorities as we have considered  relevant,  in each case
as in effect on the date hereof. It should be noted that such Code, Regulations,
judicial  decisions,  administrative  interpretations  and other authorities are
subject  to change at any time,  perhaps  with  retroactive  effect.  A material
change in any of the  materials or  authorities  upon which our opinion is based
could affect our conclusions stated herein.



     Based  upon the  foregoing  and  subject  to the  qualifications  set forth
herein,  we are of the opinion that under current U.S.  federal  income tax law,
although  the  discussion  set  forth in the  Registration  Statement  under the
heading "Material Tax  Considerations - United States Tax  Considerations"  does
not purport to summarize all possible U.S.  federal income tax  consequences  of
the exchange of Old Notes for New Notes,  the material U.S.  federal  income tax
consequences  that are generally  applicable to a U.S.  Person who exchanges Old
Notes for New Notes in the exchange  offer are set forth  therein.  Accordingly,
the  discussion  set  forth in the  Registration  Statement  under  the  heading
"Material Tax Considerations - United States Tax Considerations" is our opinion.



     This  opinion  is being  furnished  in  connection  with  the  Registration
Statement.  This opinion is expressed as of the date hereof, and we disclaim any
undertaking  to advise  you of any  subsequent  changes  of the facts  stated or
assumed herein or any subsequent  changes in applicable law. This opinion is for
your benefit and is not to be used, circulated,  quoted or otherwise referred to
for any purpose,  except that you may refer to this opinion in the  Registration
Statement.  Investors should consult their tax advisors as to the particular tax
consequences  to them of  exchanging  Old Notes  for New  Notes  and  acquiring,
holding  or  otherwise  disposing  of New  Notes,  including  the effect and the
applicability  of state,  local or foreign tax laws. Any variation or difference
in any fact from those set forth or assumed either herein or in the Registration
Statement may affect the conclusions stated herein. In addition, there can be no
assurance that the IRS will not assert contrary positions.

     In accordance  with the  requirements  of Item 601(b)(23) of Regulation S-K
under the Securities  Act, we hereby consent to the filing of this opinion as an
Exhibit to the Registration  Statement.  In giving this consent, we do not admit
that we come within the  category  of persons  whose  consent is required  under
Section 7 of the Securities  Act or the rules and  regulations of the Commission
thereunder.

                                                     Very truly yours,

                                                     LOCKE LIDDELL & SAPP LLP
