Roche shall calculate royalty payments set forth in Section 10.6 quarterly as of March 31, June 30, September 30 and December 31 (each being the last day of a reporting period). Roche shall pay such payments quarterly within [***] after the end of each reporting period in which Net Sales occur.

11.2 Late Payment

Any payment under this Agreement that is not paid on or before the date such payment is due shall bear interest, to the extent permitted by Applicable Law, at [***] above the average one-month Euro Interbank Offered Rate (EURIBOR), as reported by Reuters from time to time, calculated on the number of days such payment is overdue.

12. Taxes

Pieris shall pay all sales, turnover, income, revenue, value added, and other taxes levied on account of any payments accruing or made to Pieris under this Agreement. Roche agrees to reasonably assist Pieris in claiming exemption from such taxes and in minimizing the amount required to be so paid.

If provision is made in law or regulation of any country for withholding of taxes of any type, levies or other charges with respect to any royalty or other amounts payable under this Agreement to Pieris, then Roche shall promptly pay such tax, levy or charge for and on behalf of Pieris to the proper governmental authority, and shall promptly furnish Pieris with receipt of payment. Roche shall be entitled to deduct any such tax, levy or charge actually paid from royalty or other payment due to Pieris or be promptly reimbursed by Pieris if no further payments are due to Pieris. Each Party agrees to reasonably assist the other Party in claiming exemption from such deductions or withholdings under double taxation or similar agreement or treaty from time to time in force and in minimizing the amount required to be so withheld or deducted.

13. Auditing

13.1 Pieris’ Right to Audit

Roche shall keep, and shall require its Affiliates and Sublicensees to keep, full, true and accurate books of account containing all particulars that may be necessary for the purpose of calculating all royalties payable under this Agreement. Such books of accounts shall be kept at their principal place of business. At the expense of Pieris, Pieris shall have the right to engage an independent public accountant reasonably acceptable to Roche to perform, on behalf of Pieris an audit of such books and records of Roche and its Affiliates, its licensees and Sublicensees, that are deemed necessary by Roche’s independent public accountant to report on Net Sales of Product for the period or periods requested by Pieris, and the correctness of any financial report or payments made under this Agreement.

13.2 Audit Reports

The auditors shall only state factual findings in the audit reports and shall not interpret the agreement. The auditors shall share all draft audit reports with Roche before the draft report is shared with Pieris and before the final document is issued. The final audit report shall be shared with Roche at the same time it is shared with Pieris.

13.3 Over- or Underpayment

If the audit reveals an overpayment, Pieris shall reimburse Roche for the amount of the overpayment within [***].

Roche shall pay for the audit costs if the underpayment of Roche exceeds [***] of the aggregate amount of royalty payments owed with regard to the royalty statements subject to the audit. Section 11.2 shall apply to this Section 13.3.

13.4 Duration of Audit Rights

The failure of Pieris to request verification of any royalty calculation within the period during which corresponding records must be maintained under this Article 13 will be deemed to be acceptance of the royalty payments and reports.

When Handling its Patent Rights on Inventions made under this Agreement, Pieris shall, at its own expense, (i) consult with Roche as to the Handling of such Patent Rights, and (ii) furnish to Roche copies of all documents relevant to any such Handling. Pieris shall furnish such documents and consult with Roche in sufficient time before any action by Pieris is due to allow Roche to provide comments thereon, which comments Pieris must consider. At Pieris’ expense and reasonable request, Roche shall cooperate, in all reasonable ways with the Handling of all of Pieris’ Patent Rights relating to Inventions.

14.7 Defense

If the manufacture, use, importation, offer for sale or sale of any Product pursuant to this Agreement results in any claim, suit or proceeding alleging patent infringement or trade secret misappropriation against Pieris or a member of the Roche Group, then such Party shall promptly notify the other Party hereto. The Parties shall cooperate with each other in connection with any such claim, suit or proceeding and shall keep each other reasonably informed of all material developments in connection with any such claim, suit or proceeding.

If a Third Party asserts that Patent Rights owned by or licensed to it are infringed by the development, manufacture, use, importation, offer for sale or sale of Products by a member of the Roche Group, or that its trade secrets were misappropriated in connection with such activity, then Roche shall have the exclusive right and responsibility to resolve any such claim, whether by obtaining a license from such Third Party, by defending against such Third Party’s claims or otherwise, and shall be solely responsible for the defense of any such action, any and all costs incurred in connection with such action (including, without limitation, attorneys’ and expert fees) and all liabilities incurred in connection therewith. Notwithstanding the above, Roche shall not enter into any settlement of any such claim without the prior written consent of Pieris if such settlement would require Pieris to be subject to an injunction or to make any monetary payment to Roche or any Third Party, or admit any wrongful conduct by Pieris or its Affiliates, or would limit or restrict the claims of or admit any invalidity and/or unenforceability of any of the Patent Rights Controlled by Pieris, or have any impact on activities outside the Field.

If an action for infringement is commenced against Pieris, its licensees or its sublicensees related to Pieris’s conduct of the research program within the scope of the Research Plan or the discovery of a Product, then Pieris shall have the right (but not the obligation) to defend such action at its own expense, and Roche shall assist and cooperate with Pieris, at Pieris’ expense, to the extent necessary in the defense of such suit. Pieris shall have the right to settle the suit or consent to an adverse judgment thereto, in its sole discretion, so long as such settlement or adverse judgment does not adversely affect the rights of Roche and its Affiliates (including any patent rights Controlled by any of them). Pieris shall assume full responsibility for the payment of any award for damages, or any amount due pursuant to any settlement entered into by it with such Third Party.

If Pieris fails to commence a suit to enforce the applicable Pieris IP and to Patents relating to [***] or to settle or otherwise secure the abatement of such action or proceeding within a reasonable period, then Roche shall have the right, but not the obligation, to commence a suit or take action to enforce such Patent Rights against such infringement action or proceeding in the Field in the Territory at its own cost and expense, and only to the extent such action or proceeding is related to the Product(s).

Accordingly, the Parties agree that all such information and materials obtained by Pieris and Roche from each other will be used solely for purposes of the Parties’ common legal interests with respect to the conduct of the Agreement. All information and materials will be treated as protected by the attorney-client privilege, the work product privilege, and any other privilege or immunity that may otherwise be applicable. By sharing any such information and materials, neither Party intends to waive or limit any privilege or immunity that may apply to the shared information and materials.

PRESS RELEASE

Pieris Pharmaceuticals Announces

First Cancer Immunotherapy Collaboration

Agreement with Roche Leverages Proprietary Anticalin^® Technology Platform

Boston, MA, December 8, 2015 – Pieris Pharmaceuticals, Inc. (NASDAQ: PIRS), a biotechnology company advancing novel bio therapeutics through its proprietary Anticalin^® technology platform, today announced a research collaboration and license agreement with Roche in cancer immunotherapy (CIT). Under the terms of the agreement, Pieris will discover, characterize and optimize Anticalin^®-based drug candidates against an undisclosed target. Roche and Pieris will evaluate different drug formats against this target and advance them through preclinical development, with Roche being responsible for IND-enabling activities, clinical development and worldwide marketing of any resulting products. Pieris will receive an upfront payment of CHF 6.5 million (~$6.4 million USD) and committed research funding, and may receive development and regulatory-based milestone payments, sales-based milestone payments as well as mid single-digit to low double-digit royalties on any future product sales. If all milestones and other conditions are met, the total payments to Pieris could surpass CHF 415 million (~$409.3 million USD), excluding royalties.

“Our partnership with Roche is a significant step forward for Pieris,” commented Stephen Yoder, President and CEO of Pieris. “The decision by the leader in the development and commercialization of cancer biologics to collaborate with Pieris underscores the unique potential of Anticalin-based proteins as a differentiated class of immuno-oncology drugs. As we initiate this collaboration, we will continue to vigorously advance our fully proprietary programs, including our lead CD137-HER2 bispecific.”

With its immuno-oncology PRS-300 Series, which remains proprietary to the Company, Pieris is developing bispecific Anticalin-based protein therapeutics against a variety of tumor and immunomodulatory targets. These compounds, including its lead program PRS-343 (CD137/HER2 bispecific), aim to activate the immune system in the tumor microenvironment, with the goal of increasing efficacy as well as improving safety compared to existing approaches. This collaboration represents Pieris’ first partnered immuno-oncology program and leverages Pieris’ capability to address a target in multiple ways through Anticalin-based drug candidates in different formats.
