Important Notices:

This announcement is neither an offer to purchase nor a request to submit
an offer to sell shares in Biofrontera AG. The detailed terms of the
Amended Acquisition Offer as well as further information regarding the
Amended Acquisition Offer, are set out in the Offer Document which has been
approved by the German Federal Financial Supervisory Authority
(Bundesanstalt für Finanzdienstleistungsaufsicht - BaFin) and in the Offer
Amendment. The Acquisition Offer and the Offer Document must be read and
interpreted in conjunction with the Offer Amendment.

Investors and holders of Biofrontera-Shares or American Depositary Shares
('ADS') in Biofrontera AG ('Biofrontera-ADS') are strongly advised to read
the Offer Document and the Offer Amendment, as well as all other documents
relating to the Amended Acquisition Offer, as they contain important
information. The Amended Acquisition Offer is only for Biofrontera-Shares
and holders of Biofrontera-ADS cannot directly tender their Biofrontera-ADS
for sale in connection with the Amended Acquisition Offer. Holders of
Biofrontera-ADS who wish to accept the Amended Acquisition Offer with
regard to the Biofrontera-Shares underlying their Biofrontera-ADS are
entitled to do so but must first timely convert their Biofrontera-ADS to
Biofrontera-Shares, which can then be tendered for sale within the
framework of, in accordance with, and subject to, the terms of the Amended
Acquisition Offer set out in the Offer Document and the Offer Amendment.

Investors and holders of Biofrontera-Shares or Biofrontera-ADS may also
view a non-binding English translation of the documents, notices and
announcements pertaining to the Amended Acquisition Offer on the website of
the U.S. Securities and Exchange Commission ('SEC') (http://www.sec.gov)
free of charge as soon as they have been furnished to the SEC under cover
of Form CB and have become available on the website. Neither the SEC nor
any securities commission of any state in the U.S. has (a) approved or
disapproved of the Amended Acquisition Offer, (b) passed upon the merits or
fairness of the Amended Offer, or (c) passed upon the adequacy or accuracy
of the disclosure in this announcement. Any representation to the contrary
is a criminal offense in the U.S.

The Amended Acquisition Offer set out in the Offer Document and the Offer
Amendment refers to shares of a German company and is made exclusively in
accordance with the laws of the Federal Republic of Germany and certain
applicable provisions of the securities laws and regulations of the United
States of America and the respective applicable exemptions, in particular
the so-called 'Tier I Exemption'. As a result of the Tier I Exemption, the
Amended Acquisition Offer is generally subject to the disclosure and other
requirements and procedures of the Federal Republic of Germany that differ
from those of the United States. Any contract that is concluded on the
basis of the Amended Acquisition Offer will be governed solely by the laws
of the Federal Republic of Germany and is to be construed in accordance
with these laws.

With the exception of the permission to publish the Offer Document in
Germany and pursuant to German law, no other registrations, approvals or
authorizations of the Offer Document, the Offer Amendment or the Amended
Acquisition Offer have been or will be applied for or arranged with
securities regulators of other legal systems.
