       Bank of New York.

In this capacity, we have examined a copy of the Registration Statement.

Terms and expressions defined or referred to in the Registration Statement,
which are not otherwise defined herein, shall have the same meaning herein.

We have also examined originals or copies of the following corporate documents:

(i)    a copy of the Articles of Incorporation of Orvet Finance I dated July 9,
       2001 which according a search carried out at Luxembourg Registers open to
       the public have remained unchanged at the date hereof (the "Articles of
       Incorporation");

(ii)   an extract from the Luxembourg Commercial and Companies Register
       concerning Orvet Finance I dated September 3, 2001;

(iii)  a Power of Attorney dated December 10, 2003, issued for and on behalf of
       Orvet Finance I in favor of Steven Melkman, Th. J. Andriessen and William
       A. Fletcher and each of them (the "Powers of Attorney").

In our examination of the documents referred to above and in expressing our
opinion, we have assumed without independent verification of any kind:

- -      the genuineness of all signatures on all documents we have reviewed;

- -      the authenticity of all such documents submitted to us as originals;

- -      the conformity with the originals of all documents submitted to us as
       copies;

- -      that the Resolutions and the Powers of Attorney have not been revoked or
       amended in any way; and

                                                                     Page 2 of 5



- -      the entering into the Orvet Finance Indenture may require certain
       Luxembourg regulatory clearances, such as the change of status of Orvet
       Finance I into a licensed credit institution.

In rendering the following opinion, we are opining on the matters hereinafter
referred to, only insofar as they are governed by the laws of Luxembourg as
currently in effect and applied by the courts of Luxembourg. We have made no
investigation of and express no opinion in relation to the laws of any
jurisdiction other than Luxembourg law.

Based on and subject to the foregoing, we are of the opinion that:

1      Orvet Finance I is a limited liability company (societe anonyme) duly
       organized and existing under the laws of Luxembourg and has all requisite
       corporate power and authority to own its properties and to conduct its
       business as described in the Registration Statement and as set forth in
       its Articles of Incorporation.

2      When an Orvet Finance Indenture has been duly authorized executed and
       delivered by the parties thereto in accordance with the form thereof that
       we have reviewed, and when the specific terms of a particular series of
       Orvet Finance I Debt Securities have been duly authorized and established
       in accordance with the relevant Orvet Finance Indenture and any
       applicable underwriting or other agreement, such Orvet Finance Debt
       Securities will constitute valid and binding obligations of Orvet Finance
       I, enforceable against Orvet Finance I in accordance with its terms;
       provided that the specific terms of the relevant series of Orvet Finance
       Debt Securities do not violate mandatory provisions of Luxembourg law.

3      A competent Luxembourg court would recognise the non-exclusive
       irrevocable submission by Orvet Finance I to the jurisdiction of any of
       federal or state courts sitting in the State of New York regarding any
       matter arising out of or in relation to the obligations of Orvet Finance
       I under Orvet Finance Indentures and such submission would be binding
       upon Orvet Finance I.

4      The United States and Luxembourg do not currently have a treaty providing
       for reciprocal recognition and enforcement of judgments in civil and
       commercial matters. Therefore, a final judgment for the payment of money
       rendered by any federal or state court in the United States based on
       civil liability, whether or not predicated solely upon the federal
       securities laws of the United States, would not be directly enforceable
       in Luxembourg, but would so upon fulfilment of applicable recognition
       (exequatur) proceedings.

Our opinion is subject to the following qualifications:

(i)    the binding effect and validity of any obligations of or against Orvet
       Finance I is subject to all limitations by reason of bankruptcy,
       insolvency, moratorium, controlled management, general settlement with
       creditors, liquidation, reorganisation and other laws of general
       application relating to or affecting the rights of creditors;

(ii)   the enforcement of any obligations of or against Orvet Finance I will be
       subject to general statutory principles of Luxembourg law and no opinion
       is given herein as to the availability in a Luxembourg Court of any
       specific performance remedy, other than monetary damages, for the
       enforcement of any obligation related to Orvet Finance Indentures and
       this opinion should not be taken to imply that a Luxembourg Court would
       necessarily grant any remedy; in particular, orders for specific
       performance and injunctions will not be available;

(iii)  claims may become barred under the statutes of limitation or may be or
       become subject to defences of set-off or counterclaim;

                                                                     Page 3 of 5



(iv)   where obligations are to be performed in a jurisdiction outside
       Luxembourg they may not be enforceable in Luxembourg to the extent that
       performance would be illegal under the laws of that other jurisdiction;

(v)    any obligation to pay a sum of money in a currency other than the euro
       will be enforceable in Luxembourg in terms of euro only. Monetary
       judgments may be expressed in a foreign currency or its euro equivalent
       at the time of judgment or payment;

(vi)   obligations to make payments that may be regarded as penalties might not
       be enforceable;

(vii)  a Luxembourg court will not necessarily award costs and disbursements in
       litigation in accordance with contractual provisions in this regard;

(viii) a certificate, determination, calculation or designation of any party to
       the foregoing instruments as to any matter provided therein might be held
       by a Luxembourg court not to be conclusive, final and binding if, for
       example, it could be shown to have an unreasonable or arbitrary basis or
       in the event of manifest error;

(ix)   the admissibility as evidence of the documents before a Luxembourg Court
       or Public Authority ("autorite constituee") to which the documents are
       produced may require that the documents come with a complete or partial
       translation into French or German and registration of the documents might
       be ordered and a registration fee become payable if a document were to be
       adduced as evidence before a Luxembourg Court or exhibited before another
       official authority ("autorite constituee") in Luxembourg;

(x)    as regards jurisdiction, a Luxembourg Court may stay proceedings if
       concurrent proceedings between the same parties and on the same grounds
       have been brought previously before another Court; and

(xi)   we make no comment with regard to any representations, which may be made
       by the Orvet Finance I in the Registration Statement.

This opinion speaks as of its date and is confined to and is solely given on the
basis of the laws of Luxembourg as applied by the Luxembourg Courts and as
presently in force. We undertake no responsibility to notify any addressee of
this opinion of any change in the laws of Luxembourg or their construction or
application after the date of this opinion.

In this opinion, Luxembourg legal concepts are expressed in English terms and
not in their original French terms. The concepts concerned may not be identical
to the concepts described by the same English terms as they exist under the laws
of other jurisdictions. This opinion may, therefore, only be relied upon under
the express condition that it is given under Luxembourg law and case law and
that any issues of interpretation arising thereunder will be governed by
Luxembourg law and be brought before a Luxembourg Court.

We express no opinion as to any laws other than the laws of Luxembourg and we
have assumed that there is nothing in any other law that affects our opinion. In
particular, we have made no independent investigation of the New York law as the
basis for the opinion stated herein and do not express or imply any opinion on
such law.

We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement. By giving our consent, we do not admit that we are in
the category of persons whose consent is required under Section 7 of the Act or
the rules and regulations promulgated thereunder.

                                                                     Page 4 of 5



This opinion is being delivered to you solely for your information in connection
with the above matter. This letter addresses matters only as of the date hereof,
may not be relied upon in any manner by any other person and is not to be used,
circulated, quoted or otherwise referred to for any other purpose without our
express written permission.

Sincerely,
