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.

11.3 Method of Payment

Royalties on Net Sales and all other amounts payable by Roche hereunder shall be paid by Roche in Swiss francs (the “Payment Currency”) to account(s) designated by Pieris, except Research Costs according to Section 10.2 which shall be paid to such account(s) in Euros.

11.4 Currency Conversion

When calculating the Sales of any royalty-bearing Product that occur in currencies other than the Payment Currency, Roche shall convert the amount of such sales into the Payment Currency using Roche’s then-current internal foreign currency translation actually used on a consistent basis in preparing its audited financial statements (at the Effective Date, YTD average rate as reported by Reuters).

11.5 Reporting

With each payment Roche shall provide Pieris in writing for the relevant Calendar Quarter on a Product-by-Product and [***] (i.e. [***]) basis the following information:

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.

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.

CONFIDENTIAL TREATMENT REQUESTED

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.

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.”
