Research and License Agreement with Technische Universität München (“TUM”)

On July 4, 2003, the Company entered into a research and licensing agreement with TUM, which was subsequently renewed and, on July 26, 2007, superseded and replaced. The agreement established a joint research effort led by Prof. Arne Skerra, Chair of Biological Chemistry of TUM, to optimize Anticalin technologies for use in therapeutic, prophylactic and diagnostic applications and as research reagents, and to gain fundamental insights in lipocalin scaffolds. Prof. Dr. Skerra was a member of the Company´s supervisory board when the parties entered into such agreement and during the period covered by the consolidated financial statements in this report. The Company provided certain funding for TUM research efforts performed under the agreement.

As a result of research efforts to date under the agreement, the Company holds a worldwide exclusive license under its license agreement with TUM to multiple patents and patent applications, including an exclusive license to an issued U.S. patent, which patent will expire in 2027 (subject to a possible term adjustment period). The Company also holds an exclusive license to an issued U.S. patent No. 8,420,051, which patent is expected to expire in 2029. The Company bears the costs of filing, prosecution and maintenance of patents assigned or licensed to the Company under the agreement.

As consideration for the assigned patents and licenses above, the Company is required to pay certain development milestones to TUM. The Company also is obliged to pay low-single-digit royalties, including annual minimum royalties, on sales of such products incorporating patented technologies. If the Company grants licenses or sublicenses to those patents to third parties, the Company will be obliged to pay a percentage of the resulting revenue to TUM. The Company’s payment obligations are reduced by the Company’s proportionate contribution to a joint invention. Payment obligations terminate on expiration or annulment of the last patent covered by the agreement. The Company can terminate the licenses to any or all licensed patents upon specified advance notice to TUM. TUM may terminate the license provisions of the agreement only for cause. Termination of the agreement does not terminate the rights in patents assigned to the Company.

Effective as of the fourth quarter of 2015, the Company no longer deems TUM a related party due to Prof. Dr. Skerra no longer having a supervisory board position in Pieris GmbH or other direct relationship with the Company since its initial public offering in December 2014. Therefore no expenses to TUM as a related party were incurred during the three months ended March 31, 2016. The Company incurred expenses related to TUM as a related party of approximately $14,000 for the three months ended March 31, 2015.

Consulting Contract between Prof. Dr. Arne Skerra and Pieris AG

In 2001, the Company entered into a Consulting Agreement with Prof. Dr. Arne Skerra, pursuant to which Prof. Dr. Arne Skerra provides advice regarding the use of new proteins, in particular Anticalin proteins and antibodies, for the purpose of research and development. As of the fourth quarter of 2015, Pieris no longer deems Prof. Dr. Skerra a related party due to Prof. Dr. Skerra no longer having a supervisory board position in Pieris GmbH or other direct relationship with the Company after its initial public offering in December 2014. The Company incurred and paid to Prof. Dr. Skerra consulting fees of approximately $6,000 for the three months ended March 31, 2015.
