Subject to the foregoing limitation, the Reporting Entities (other than the Reporting Individuals and VVB) currently intend to acquire additional voting securities of the Issuer, or instruments convertible into voting securities of the Issuer to the extent possible at reasonable prices in order to maintain their current ownership positions. Any such acquisitions may be effected through open market purchases, block trades, privately-negotiated transactions, subscriptions made pursuant to rights offerings by the Issuer, or otherwise (including the exercise of any options or other securities exercisable for, or convertible into, any such securities of the Issuer).

The Reporting Persons (other than the Reporting Individuals and VVB) may also dispose of voting securities of the Issuer from time to time.

On July 6, 2021, the Issuer announced that its US-subsidiary Biofrontera Inc. intends to raise capital by means of an initial public offering and a stock exchange listing in the United States (“IPO”).

On September 19, 2021, the Pool Members requested to call a general shareholders meeting of the Issuer with regard to the intended IPO of Biofrontera Inc. and proposed to elect a special auditor concerning the circumstances of the IPO. On October 5, 2021, the Pool Members applied for authorization by the local court of Cologne to call a general shareholders meeting of the Issuer and also to authorize the Pool Members to publish and therewith put such proposals to the agenda of the next shareholders meeting of the Issuer.

On October 13, 2021, the Pool Members applied for calling a general meeting and an amendment to the agenda of the next shareholders meeting of the Issuer and proposed to vote against the IPO of Biofrontera Inc. and to elect a special auditor regarding the circumstances of the intended IPO. Such application is now pending with the local court of Cologne.

On November 2, 2021, the Issuer announced that at the closing of the IPO, Biofrontera Inc. placed 3,600,000 Units consisting of (i) one share of Biofrontera Inc. common stock and (ii) one warrant entitling the holder to purchase one additional share of Biofrontera Inc. common stock at an exercise price of $5.00. The underwriters exercised in full their option to purchase up to an additional 540,000 warrants to cover over-allotments. Each warrant has expires five years after the date of issuance. The gross proceeds to Biofrontera Inc. from the offering, before deducting the underwriting discounts and commissions and offering expenses, amount to approximately $18,000,000.

On November 19, 2021, the Issuer announced the results of the mediation proceedings with Mr. Wilhelm K. T. Zours and DB. In the course of the mediation process, an agreement (the “Settlement Agreement”) was entered among each of the Reporting Entities, Maruho Deutschland GmbH (“Maruho”), Mr. Zours and the Issuer. Pursuant to the Settlement Agreement, (i) the Reporting Entities and Maruho agreed to vote in favor of the election of the following candidates in the upcoming Annual General Meeting: Dr. Heikki Lanckriet; Dr. Helge Lubenow; Mrs. Prof. Franca Ruhwedel; Mr Karlheinz Schmelig; Dr. Jörgen Tielmann; and Mr Wilhelm K. T. Zours, and (ii) the Issuer, DB, DU and ABC agreed to withdraw outstanding lawsuits. Mr. Zours has declared his willingness to stand for election as Chairman of the Supervisory Board. The Settlement Agreement also provides that the authorized capital resolved by the Annual General Meeting of the Issuer on May 24, 2017 under agenda item 6, which is the subject of a pending action for rescission, and which would in any case be limited until May 23, 2022, is not to be used even after the withdrawal of the action.. The Settlement Agreement does not include a review regarding the background of the IPO of Biofrontera Inc. The terms of the Settlement Agreement are subject to the condition precedent that the aforementioned candidates are elected to the Supervisory Board of the Issuer by no later than December 31, 2021.

In order to ensure that the Issuer will be able to raise further capital in the future, on November 26, 2021 DB submitted with the Issuer an amendment to the agenda of the annual general meeting to be held on December 14, 2021 with the proposals to adopt authorized capital and contingent capital. DB proposed a maximum authorized capital of 50% of the current share capital as well as a maximum contingent capital of 50% of the current share capital, both valid for five years.

On November 26, 2021, the Pool Members withdrew the proposal to elect a special auditor regarding the circumstances of the intended IPO.
