Dear Sirs,

                             STMicroelectronics N.V.
                                SEC Registration
                           of 30,892,500 common shares
                 in the share capital of STMicroelectronics N.V.

1      Introduction

       I have acted on behalf of De Brauw Blackstone Westbroek N.V. as Dutch
       legal adviser (advocaat) to STMicroelectronics N.V., with corporate seat
       in Amsterdam, (the "Company") in connection with the registration (the
       "Registration") by the Company with the United States Securities and
       Exchange Commission (the "SEC") of 30,892,500 common shares, each having
       a nominal value of EUR 1.04, in the Company's share capital, to be newly
       issued by the Company upon the exercise of rights to subscribe for shares
       in the Company's share capital (the "Options") granted under the Plans
       (as defined below) (the "Shares"). I have taken instructions solely from
       yourselves.

2      Dutch Law

       This opinion is limited to Dutch law as applied by the Dutch courts and
       published and in effect on the date of this opinion. It is given on the
       basis that all matters relating to it will be governed by, and that it
       (including all terms used in it) will be construed in accordance with,
       Dutch law.

3      Scope of Inquiry; definitions

       For the purpose of this opinion, I have examined the following documents:



3.1    A photocopy of a notarial copy of the Company's deed of incorporation, a
       photocopy of a notarial copy of the deed of the Company's transformation
       from a private company with limited liability into a limited liability
       company and the Company's articles of association as most recently
       amended on 13 June 2002 according to the trade register extract referred
       to in paragraph 3.2, all as filed with the chamber of commerce and
       industry for Amsterdam (the "Chamber of Commerce").

       Supervisory Board Members and Professionals of the Supervisory Board
       stated to have become effective as of 24 April 2002 (the "2002 Plan" and,
       together with the 2001 Plan, the "Plans" and each a "Plan").

3.4    Photocopies of the minutes of the Company's general meetings of
       shareholders held on 31 May 1999, 25 April 2001 and 27 March 2002,
       respectively, including resolutions to designate the Company's
       supervisory board (raad van commissarissen) as the corporate body
       authorised to resolve to grant rights to subscribe for shares in the
       Company's share capital up to the authorised share capital and to exclude
       all pre-emption rights (voorkeursrechten) in respect thereof (the
       "Delegations").

3.5    A photocopy, received by me on 19 May 2003, of an extract from the
       minutes (extrait du proces verbal) of the meeting of the Company's
       supervisory board held on 12 March 2001 including resolutions relating to
       the 2001 Plan.

3.6    Photocopies, received by me on 19 May 2003, of written resolutions of the
       Company's compensation committee and of the Company's supervisory board,
       respectively, each dated 14 March 2003, and each in respect of a grant of
       Options under the 2001 Plan (hereinafter collectively: the "2001 Plan

       a stock option agreement for the 2002 Plan.



3.11   A print of an e-mailed copy, received by me on 26 September 2003, of a
       draft of a registration statement on Form S-8 relating to the
       Registration (excluding the documents incorporated in the registration
       statement by reference and any annexes to it) (the "Registration
       Statement").

       In addition, I have obtained the following confirmations given by
       telephone on the date of this opinion:

3.12   Confirmation from the Chamber of Commerce that the trade register extract
       referred to in this paragraph 3 is up to date in all material respects.

3.13   Confirmation from the office of the bankruptcy division
       (faillissementsgriffie) of the Amsterdam district court that the Company
       is not registered as having been declared bankrupt or granted suspension
       of payments.

       My examination has been limited to the text of the documents and I have
       not investigated the meaning and effect of any document governed by a law
       other than Dutch law under that other law.

4      Assumptions


       For the purpose of this opinion, I have made the following assumptions:

4.1    All copies of documents conform to the originals and all originals are
       genuine and complete.

4.2    Each signature is the genuine signature of the individual concerned.

4.3    The minutes and extracts from minutes referred to in paragraph 3 are a
       true record of the proceedings described in them in duly convened,
       constituted and quorate meetings and the resolutions set out in those
       minutes and any other resolutions referred to in paragraph 3, (i) were
       validly passed and remain in full force and effect without modification,
       and (ii) comply with the requirements of reasonableness and fairness
       (redelijkheid en billijkheid) under Dutch law. Any confirmation referred
       to in paragraph 3 is true.

4.4    The Registration Statement has been or will have been filed with the SEC
       in the form referred to in paragraph 3.

4.5    The Plans have been adopted in the forms referred to in paragraph 3.

4.6    The Company's supervisory board will have adopted one or more further
       resolutions for the grant of options under the 2001 Plan similar, in all
       material respects, to the 2001 Plan Option Grant Resolutions (the
       "Further 2001 Plan Option Grant Resolutions") and/or one or more further
       resolutions for the grant of options under the 2002 Plan similar, in all
       material respects, to the 2002 Plan Option Grant Resolutions (the
       "Further 2002 Plan Option Grant Resolutions" and together with the
       Further 2001 Plan Option Grant



       Resolutions, the "Further Option Grant Resolutions"). The Further Option
       Grant Resolutions (i) will have been validly passed or adopted and will
       remain in full force and effect without modification, and (ii) will
       comply with the requirements of reasonableness and fairness (redelijkheid
       en billijkheid) under Dutch law.

4.7    The Options granted under the 2001 Plan have been granted exclusively to
       employees of the Company and its group companies (within the meaning of
       Section 2:24b Civil Code (Burgerlijk Wetboek).

4.8    The 2002 Plan Option Grant Resolutions and the Further 2002 Plan Option
       Grant Resolutions can be deemed to contain an exclusion of all
       pre-emption rights in respect of the Options granted thereby.

4.9    By means of the 2001 Plan Option Grant Resolutions, the 2002 Plan Option
       Grant Resolutions and the Further Option Grant Resolutions the Company
       will have granted Options for an aggregate of 30,892,500 Shares.

4.10   The Options granted and accepted under the 2001 Plan (the "2001 Options")
       have been or will have been granted and accepted in accordance with the
       provisions of the 2001 Plan. The Options granted and accepted under the
       2002 Plan (the "2002 Options") have been or will have been granted and
       accepted in accordance with the provisions of the 2002 Plan.

4.11   All Shares issued and to be issued pursuant to the exercise of Options
       are newly issued Shares.

4.12   At the time of issue both the Company's authorised share capital
       (maatschappelijk kapitaal) and the relevant Delegation are sufficient to
       allow for the issue of the Shares.

4.13   The Shares will have been (i) issued in the form and manner prescribed by
       the Company's articles of association at the time of issue and (ii)
       validly accepted by the Option holders exercising their Options.

4.14   The nominal amount of the Shares and any agreed share premium will have
       been validly paid.

4.15   The Options will have been granted by the Company and accepted and
       exercised by the Option grantees, and the Shares will have been issued by
       the Company and accepted by the exercising holders of Options, in
       accordance with all applicable laws (including, for the avoidance of
       doubt, Dutch law and including, without limitation, that the Options are
       offered within a closed circle (besloten kring) to the Company's or its
       group companies' (within the meaning of Section 2:24b Civil Code
       (Burgerlijk Wetboek)) employees or to non-residents of the Netherlands in
       compliance with the requirements of section 3 of the Exemption Regulation
       under the 1995 Act on the supervision of the securities trade
       (Vrijstellingsregeling Wet toezicht effectenverkeer 1995) and that
       insider trading (voorwetenschap) rules under the 1995 Act on the
       supervision of the securities trade (Wet toezicht effectenverkeer 1995)
       are complied with).



5      Opinion

       Based on the documents and confirmations referred to and the assumptions
       in paragraphs 3 and 4 and subject to the qualifications in paragraph 6
       and to any matters not disclosed to me, I am of the following opinion:

       The Shares will have been duly authorised and, when issued, will have
       been validly issued in accordance with Dutch law and fully paid. The
       holders of the Shares will not be liable for the Company's obligations,
       except in the case of abuse of the Company's legal personality and other
       exceptional circumstances.

6      Qualifications

       This opinion is subject to the following qualifications:

6.1    This opinion is subject to any limitations arising from bankruptcy,
       insolvency, liquidation, moratorium, reorganisation and other laws of
       general application relating to or affecting the rights of creditors.

6.2    The trade register extract referred to in paragraph 3 does not provide
       conclusive evidence that the facts set out in it are correct. However,
       under the 1996 Trade Register Act (Handelsregisterwet 1996), subject to
       limited exceptions, a company cannot invoke the incorrectness or
       incompleteness of its trade register registration against third parties
       who were unaware of it.

6.3    The confirmation from the office of the bankruptcy division referred to
       in paragraph 3 does not provide conclusive evidence that the Company has
       not been declared bankrupt or granted suspension of payments.


7      Reliance

       This opinion is solely for the purpose of the Registration. It is not to
       be transmitted to anyone nor is it to be relied upon for any other
       purpose or quoted or referred to in any public document or filed with
       anyone without my written consent except that it may be filed with the
       SEC as an exhibit to the Registration Statement (but I do not admit that
       I am a person whose consent for that filing is required under Section 7
       of the United States Securities Act of 1933, as amended).

Yours faithfully,

J.J.J. Schutte
