Dear Ladies and Gentlemen :
In connection with the Registration Statement on Form F-4 (the
"Registration Statement") filed by BROKAT Aktiengesellschaft, a German
corporation (the "Company"), with the US Securities and Exchange Commission
pursuant to the Securities Act of 1933, as amended (the "Act"), and the rules
and regulations thereunder (the "Rules"), we have been requested to render our
opinion as to the matters hereinafter set forth. Capitalized terms used and not
otherwise defined herein shall have the meanings attributed thereto in the
Registration Statement.

RECHTSANWALTE
In this regard, we have reviewed copies of the Registration
Statement (including the exhibits and appendices thereto). We have also made
such other investigations of fact and law and have examined the originals, or
copies authenticated to our satisfaction, of such other documents, records,
certificates or other instruments as in our judgment are necessary or
appropriate to render the opinion expressed below.
The opinion set forth below is limited to the tax laws of
Germany, all as in effect on the date hereof. The statutory provisions,
regulations, and interpretations upon which our opinion is based are subject to
change, and such changes could apply retroactively. Any such change could affect
the continuing validity of the opinion set forth below. We assume no
responsibility to advise you of any subsequent changes in existing law or facts,
nor do we assume any responsibility to update this opinion with respect to any
matters expressly set forth herein, and no opinions are to be implied or may be
inferred beyond the matters expressly so stated.
Based upon and subject to the foregoing, we confirm that the
opinion of Gleiss, Lutz, Hootz, Hirsch set forth in the Registration Statement
under the heading "Material Tax Consequences-German Taxation" constitutes our
opinion with respect to such matters.
We hereby consent to the filing of this opinion as an exhibit
to the Registration Statement, or any amendment pursuant to Rule 462 under the
Act. In giving this consent, we do not hereby agree that we come within the
category of persons whose consent is required by the Act or the Rules.
Very truly yours,
/s/ Hansjorg Scheel
