Telvent GIT, S.A.
Valgrande, 6
28108 Alcobendas, Madrid
Spain

Ladies and Gentlemen:

         We are familiar with the proceedings taken and proposed to be taken by
Telvent GIT, S.A., a sociedad anonima organized under the laws of the Kingdom of
Spain (the "Company"), in connection with the registration under the Securities
Act of 1933, as amended (the "Act"), of 10,005,000 Ordinary Shares (the
"Shares"). As your counsel, we have collaborated in the preparation of the
Registration Statement on Form F-1 (the "Registration Statement") to be filed by
you with the Securities and Exchange Commission as of the date hereof to effect
the registration pursuant to the Act of the Shares.

         Attorneys involved in the preparation of this opinion are admitted to
practice law only in the Kingdom of Spain and we express no opinion herein
concerning any law other than the federal laws of the Kingdom of Spain.

         In connection therewith, we prepared the discussion set forth under the
caption "Taxation - Spanish Taxation" in the Prospectus forming a part of the
Registration Statement. We hereby confirm that the discussion under the caption
"Taxation - Spanish Taxation", insofar as such discussion represents legal
conclusions or statements of Spanish tax law, unless otherwise noted and subject
to the limitations and qualifications therein, constitutes our opinion as to the
material Spanish tax consequences of the acquisition, ownership and disposition
of the Shares by a "nonresident holder" (as such term is defined in the
Prospectus).

         The opinions set forth herein are rendered as of the date hereof, and
we assume no obligation to update such opinions to reflect any facts or
circumstances which hereafter may come to our attention or any changes of law
which hereafter may occur. We consent to the reference to our Firm wherever
appearing in the Registration Statement and to the inclusion of this opinion as
an exhibit to the Registration Statement. In giving such consent, we do not
admit hereby that we come within the category of persons whose consent is
required under Section 7 of the Act or the rules and regulations promulgated
thereunder.

                                         Sincerely,



                                         /s/ Squire, Sanders & Dempsey L.L.P.
                                         ------------------------------------
                                         Squire, Sanders & Dempsey L.L.P.
