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 400,000,000 6 1/2%
Senior  Secured Notes due 2013 (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 "Material 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
