Dear Sirs,

We act as solicitors in Ireland for the Issuer, the Parent and the Guarantor
(each a "Company" and together, the "COMPANIES") with respect to the issue by
the Issuer of the Euro PIK Notes and the Dollar PIK Notes (collectively, the
"PIK Notes"), the issue by the Parent of the Warrants, the issue by the Issuer
and the Parent of the Euro Units and the Dollar Units representing the PIK Notes
and the Warrants (COLLECTIVELY, the "UNITS") and the issue by the Issuer of the

and 2nd October 2002 in respect of the Units (the "UNITS CLOSING DATE", and
together with the Notes Closing Date, the "CLOSING DATES") and their exchange
into PIK Notes and Notes registered with the Securities and Exchange Commission
(the

<Page>

"SEC"). The ordinary shares that are issued upon the exercise of the Warrants in
accordance with the terms of the Warrant Agreement (as defined below) are
hereinafter referred to as the "WARRANT SHARES". The issue of the Units, the PIK
Notes, the Warrants and Exchange Notes is hereinafter referred to as the
"Transaction" and we are giving this opinion solely in connection with the entry
into and performance of the Documents (as defined in paragraph 1D below) by the
Companies. We give this opinion on the basis and subject to the comments,
assumptions and qualifications set out below. Capitalised terms used in this
opinion shall have the same meaning as is ascribed to such terms in the
Documents, unless otherwise defined herein.

1.       BASIS OF OPINION

         1A.      This opinion is furnished to you in connection with the filing
                  of the Registration Statement (as defined below) and is not to
                  be used, circulated quoted or otherwise relied upon for any
                  other purpose. We also hereby consent to the filing of this
                  opinion as an exhibit to the Registration Statement.

         1B.      This opinion is confined to and given in all respects with
                  respect to the laws of Ireland (meaning Ireland exclusive of
                  Northern Ireland) in force as at the date hereof as currently
                  applied by the Irish courts (excluding any foreign law to
                  which reference may be made under the rules of Irish private
                  international law). No opinion is expressed or implied as to
                  any Irish taxation matters or their effect on the Documents or
                  the transactions contemplated thereby. No opinion is expressed
                  or implied as to the laws of or the effect on the Documents or
                  the transactions contemplated thereby of, any other
                  jurisdiction. We have assumed without investigation that
                  insofar as the laws of any jurisdiction other than Ireland are
                  relevant, such laws do not prohibit and are not inconsistent
                  with any of the obligations or rights expressed in the
                  Documents or the transactions contemplated thereby. We have
                  made no investigations of and we express no opinion as to the
                  laws of any other jurisdiction or the effect thereof. In
                  particular, we express no opinion on European Community law as
                  it affects any jurisdiction other than Ireland or any matter
                  of fact.

         1C.      This opinion is also strictly confined to the matters stated
                  herein and is not to be read as extending, by implication or
                  otherwise, to any other matter. We express no opinion and make
                  no representation or warranty as to any matter of fact or in
                  respect of any documents or arrangements which may exist in
                  relation to the Documents

         1D.      For the purpose of giving this opinion, we have reviewed the
                  following documents:

                           (i) Copies of the certificate of incorporation,
                           certificate(s) of incorporation on change of name (if
                           any) and the memorandum and articles of association
                           of each Company;

                           (ii) copy of the certificate of a public company
                           entitled to do business of the Issuer;

                           (iii) copies of written resolutions of each director
                           of the board of directors of each Company (each, a
                           "Board Resolution");

                           (iv) officers and secretary's certificates of
                           appropriate officers of each Company confirming
                           certain factual circumstances regarding the Companies
                           and the Transacted Documents;


                                       2
<Page>

                           (v) a copy of a Form F4 Registration Statement
                           prepared by the Companies in connection with the
                           PIK Notes and the Notes (the "Registration
                           Statement");

                           (vi) The Indentures relating to the Notes and the PIK
                           Notes;

                           (vii) the PIK Notes and the Notes; and

                           (viii) the Registration Rights Agreements pursuant to
                           which the PIK Notes and the Notes will be registered
                           with the SEC.

         References in this opinion to the "Transaction Documents" means the
         documents listed from (vi) to (viii) above.

         1E.      For the purpose of giving this opinion, we have caused to be
                  made the following legal searches:

                  (1)      28th March, 2003 on the files of the Companies
                           maintained by the Registrar of Companies in Dublin,
                           Ireland for the appointment of any receiver, examiner
                           or liquidator;

                  (2)      on 28th March, 2003, in the Judgments Office of the
                           High Court in Dublin, Ireland for unsatisfied
                           judgments, orders or decrees in relation to the
                           Companies; and

                  (3)      on 28th March, 2003 in the Central Office of the High
                           Court in Dublin, Ireland for any proceedings or
                           petitions filed in the last two years against the
                           Companies.

         1F.      We have not conducted, nor have we been requested to conduct
                  any due diligence on any of the Companies for the purpose of
                  the Transaction nor have we conducted any verification of the
                  Registration Statement. Accordingly we do not, nor have we
                  been requested to, express any opinion on the adequacy of the
                  disclosure set out in the Registration Statement.

         1G.      This opinion is to be construed in accordance with the laws of
                  Ireland as at the date hereof.

2.       OPINION

         On the basis of and subject to the assumptions and qualification set
         out below and any matters not disclosed to us, we are of the opinion
         that:


         2A.      The Issuer is a public limited company, the Guarantor is a
                  public unlimited company, the Parent is a private limited
                  company, each duly incorporated and validly existing under the
                  laws of Ireland.

         2B.      Each Company has the power under its memorandum and articles
                  of association referred to above to enter into the Transaction
                  Documents (including the Notes and the guarantee therein) and
                  to perform its obligations thereunder and had, on the


                                       3
<Page>

                  Closing Dates, taken all necessary corporate and other action
                  to authorise the execution, delivery and performance of the
                  Transaction Documents (including the Notes and the guarantee
                  therein) and each Transaction Document (including the Notes
                  and the guarantee therein) has been duly executed and
                  delivered by each Company party thereto.

3.       ASSUMPTIONS

         For the purpose of giving this opinion, we have made the following
         assumptions (without any responsibility on our part if any assumption
         proves to be untrue or incorrect) which we have taken no steps to
         verify independently.

         3A.      All documents submitted to us as originals are authentic,
                  accurate and complete as at the date hereof and were
                  authentic, accurate and complete on the Closing Date and all
                  documents supplied to us as photocopies or facsimile
                  transmitted copies or other copies conform to the originals
                  and such originals are authentic, accurate and complete (and
                  were authentic, accurate and complete on the Closing Dates)
                  and the originals were executed in the manner appearing on the
                  copies and that all copies and all documents on which we have
                  relied remain accurate and complete at the date of this
                  opinion letter. Without limitation to the foregoing, we have
                  assumed that the statements set out in the secretary's and
                  officer's certificates referred to above were accurate and
                  complete on the Closing Dates and continue to be accurate and
                  complete on the date hereof.

         3B.      The genuineness, completeness and authenticity of all
                  signatures on all original and copy documents which we have
                  examined.

         3C.      The documents listed in paragraph 1D of this opinion letter
                  contain all relevant information which is material for the
                  purposes of our opinion and there is no other agreement,
                  instrument, undertaking, obligation, representation or
                  warranty (oral or written) and no other arrangement (whether
                  legally binding or not) made by or between all or any of the
                  parties to the Documents or any other matter which renders
                  such information inaccurate, incomplete or misleading or which
                  affects the conclusions stated in this opinion letter and that
                  the execution, delivery, issue and performance of the
                  Documents, the Notes, the PIK Notes and the Warrants will not
                  result in any breach of any instrument, agreement or
                  obligation to which any Company is a party or to which it is
                  subject as the case may be.

         3D.      All documents, forms and notices which should have been
                  delivered to the Companies Registration Office (the
                  "Registries") on behalf of or relating to the Companies have
                  been so delivered and the file of records maintained at the
                  Registries concerning the Companies, and reproduced for public
                  inspection, were complete, accurate and up-to-date at the time
                  of the searches referred to in paragraph 1E above.

4.       QUALIFICATION

         4A.      We have not conducted any other searches whatsoever in
                  relation to the Companies nor have we carried out any due
                  diligence or made any further enquiries (either of you or of
                  the Companies) and accordingly, this opinion is given on the
                  assumption that such searches, due diligence or enquiries (if
                  made) would not reveal any circumstances which would require
                  amendment of this opinion. Furthermore, one cannot rely
                  entirely on the accuracy and completeness of the information
                  disclosed in the searches referred to in paragraph 1E above.
                  This is because such searches do not


                                       4
<Page>

                  necessarily contain completely up-to-date information and do
                  not necessarily reveal, inter alia, whether or not a
                  resolution has been passed or petition presented or any other
                  action taken for the winding up of, or the appointment of a
                  receiver or examiner of or to, the Companies. However, we draw
                  your attention to the fact that the directors' certificates
                  reviewed by us have confirmed that no such events have
                  occurred.

Yours faithfully,


/s/ Arthur Cox
