8.2.3.6. [***]. During the Term and with respect to each Product that has entered clinical Development, AstraZeneca hereby covenants not to initiate a Clinical Study with [***] against the same Target (including the primary receptor(s) and/or primary ligand(s) of such Target (as applicable) as included on the Reservation List) to which such Product is directed. In case AstraZeneca initiates a Clinical Study with a [***] against the same Target as a Product before such Product has entered clinical Development, then AstraZeneca shall notify Pieris in writing (“[***]

Notice”) and Pieris shall be entitled to terminate this Agreement with respect to such Product by notice in writing to AstraZeneca within [***] ([***]) [***] of the date of the [***] Notice with the consequences set out in Section 14.3.1.

8.2.3.7. Pieris Opt-In Right for Competing Products. No earlier than [***] ([***]) days prior to the expected First Commercial Sale of a Product (the “Existing Product”) in the United States but no later than the actual date of First Commercial Sale of such Product in the United States, AstraZeneca (including its Affiliates) will notify Pieris of any Competing Product (regardless of the stage of Development) with respect to the Existing Product and provide a non-confidential summary of any such related Competing Product(s) in its pipeline as such time (the “Program Notice”). If Pieris desires to evaluate such Competing Product, then Pieris will notify AstraZeneca within [***] ([***]) days of its receipt of the Program Notice (the “Evaluation Notice”). Promptly after AstraZeneca’s receipt of such Evaluation Notice, AstraZeneca will provide Pieris with a confidential data package relating to the related Competing Product(s) including all material pre-clinical, clinical, and Manufacturing data as well as the proposed Development plan and budget (such budget to include all Development Costs) up to [***] (as well as such other information that Pieris may reasonably request), which data package will be deemed to be Confidential Information of AstraZeneca under this Agreement (and Pieris shall be entitled to use such Confidential Information solely for the purpose of evaluating whether to include such Competing Product in the Agreement). AstraZeneca shall also respond to any of Pieris’ reasonable inquiries regarding such related Competing Products during the Evaluation Period. Within [***] days of its receipt of such confidential data package (the “Evaluation Period”), Pieris will notify AstraZeneca of its election to (i) include the Competing Product in the Agreement and share the Development Costs (including Development Costs incurred by AstraZeneca from [***] (1) with AstraZeneca on an [***] split basis (the “[***]”), (2) on a [***] percent ([***]%)-[***] percent ([***]%) basis, with Pieris contributing [***] percent ([***]%) of the Development Costs (the “[***] Split Option”), or (3) in the alternative, should the total budget of Development Costs up to [***] provided by AstraZeneca under this Section 8.2.3.7 exceed [***] Dollars ($[***]), then Pieris may elect to contribute [***] of the Development Costs associated with the Continued Development and Manufacture of the related Competing Product up to a cap of [***] Dollars ($[***]) (the “[***] Cap Option”) or (ii) decline to include the Competing Product(s) in the Agreement. If Pieris agrees in writing to include such Competing Product in the Agreement, then (a) the Competing Product will be included [***] and Pieris will elect the [***], [***] Split Option or [***] Cap Option; (b) such Competing Product will be deemed to be a Product hereunder; (c) the JDC will develop a Development Plan and budget for such Competing Product, for review and

approval by the JSC; and (d) the Parties will enter into an amendment or supplement to this Agreement to the extent necessary to specify such other changes, modifications and assignments as are reasonably necessary to effectuate the addition of such Competing Product to the collaboration consistent with this Section 8.2.3.7. If Pieris declines to include such Competing Product in the Agreement, then (i) from and after the date of such election, the non-compete obligations of AstraZeneca set forth in this Section 8.2 will no longer apply with respect to such Competing Product, and (ii) Pieris shall destroy the confidential data package of the Competing provided to it by AstraZeneca (provided, that Pieris shall be entitled to retain one (1) copy of such information for its record-keeping purposes). Furthermore, should AstraZeneca or its Affiliates acquire or in-license a [***] Competing Product (which was not in AstraZeneca’s pipeline at the time of the First Commercial Sale of the Existing Product) (A) within [***] ([***]) years of the First Commercial Sale of the Product if a [***] of the Competing Product has been Initiated at the time of in-licensing or acquisition, (B) within [***] ([***]) years of the First Commercial Sale of the Product if a [***] of the Competing Product has been Initiated at the time of in-licensing or acquisition, or (C) within [***] ([***]) years of the First Commercial Sale of the Product if a [***] the Competing Product at the time of in-licensing or acquisition, then AstraZeneca shall offer to Pieris to include such Competing Product in the Agreements under the same terms and evaluation timelines as set forth above in this Section 8.2.3.7. For avoidance of doubt, in each of the foregoing cases (clauses (A)-(C) above), the terms of such election shall be governed by the process set forth above with AstraZeneca providing the Program Notice within [***] days of the acquisition or in-license of such Competing Product.

8.2.3.8. If AstraZeneca is in material breach of this Section 8.2 with respect to a Product, then Pieris shall have the right to terminate this Agreement with respect to such Product with the consequences set out in Sections 14.3.1.

8.2.4. Effect of Acquisition. Notwithstanding Sections 8.2.1–8.2.3, each Party acknowledges that the other Party (the “Concerned Party”) may be acquired by or merge with a Third Party or acquire a Third Party during the Term of this Agreement (such transaction, an “Acquisition Transaction”, and such Third Party, the “Acquiror” or “Acquiree”). In such event, if the Acquiror or Acquiree (or a Third Party that is an Affiliate of such Acquiror or Acquiree prior to and following the date of such Acquisition Transaction) was Researching, Developing, Manufacturing or Commercializing one or more Competing Product(s) prior to the closing of such Acquisition Transaction (each an “Acquired Competing Product”), subject to the Concerned Party’s compliance with this Section 8.2.4, such Concerned Party shall be deemed not to be in breach of Sections 8.2.1–8.2.3:

CONFIDENTIAL TREATMENT REQUESTED

(b) Divest to a Third Party or discontinue the Acquired Competing Product within [***] ([***]) months after the closing date of the Acquisition Transaction; or

(c) contribute the Acquired Competing Product to the collaboration with Pieris at terms mutually acceptable to both Parties. For clarity, should Pieris and AstraZeneca not agree on such terms, then AstraZeneca has to elect either option (a) or (b) above.

8.2.4.2. If the Concerned Party is Pieris and Pieris has been acquired by a Third Party, then Pieris (or the Acquiror) shall make one of the following elections within [***] of the close of the Acquisition Transaction:

(a) Divest to a Third Party or discontinue the Acquired Competing Product within [***] ([***]) months after the closing date of the Acquisition Transaction;

(b) if the Product corresponding to the Acquired Competing Product has not reached [***] and (i) AstraZeneca requests Pieris to complete Development through that stage, then Pieris shall complete such Development and AstraZeneca shall take over further Development and Commercialization efforts for such Product alone under the terms and conditions of this Agreement (i.e., if Pieris would have had a CoDev Option or Co-Commercialization Option with respect to such Product, it shall no longer have such Options) or, (ii) otherwise, further development of the Product will be terminated and in the case of both (i) and (ii) the Pieris Acquiror or Acquiree shall be subject to no further restrictions with respect to the Acquired Competing Product and may Develop, Manufacture and Commercialize such Competing Product provided that Pieris and its Affiliates shall not use and shall not permit the Acquiror or Acquiree to use the Intellectual Property Rights granted to AstraZeneca under this Agreement or the Platform Agreement in relation to such activities;

(c) if the Product corresponding to the Acquired Competing Product has reached [***] and Pieris does not have or has not yet exercised a CoDev Option and Co-Commercialization Option for such Product, then no changes are required except that Pieris would lose any CoDev Option and Co-Commercialization Option for such Product (if any) and the Pieris Acquiror or Acquiree shall be subject to no further restrictions with respect to the Acquired Competing Product and may Develop, Manufacture and Commercialize such Acquired Competing Product provided that Pieris and its Affiliates shall not use and shall not permit the Acquiror or Acquiree to use the Intellectual Property Rights granted to AstraZeneca under this Agreement or the Platform Agreement in relation to such activities;

(d) if the Product corresponding to the Acquired Competing Product is one where Pieris has exercised a CoDev Option, then Pieris shall [***] shall apply with respect to future payments due; or

(e) contribute the Acquired Competing Product to the collaboration with AstraZeneca at terms mutually acceptable to both Parties. For clarity, should Pieris and AstraZeneca not agree on such terms then Pieris has to elect one of options 8.2.4.2(a), (b), (c) or (d).

8.2.4.3. If the Concerned Party is Pieris and Pieris has acquired the Third Party, then within [***] ([***]) [***] of the close of the Acquisition Transaction Pieris shall offer to contribute the Acquired Competing Product to the collaboration with AstraZeneca at terms mutually acceptable to the Parties. If the Parties are unable to agree on the terms of such transaction then Pieris shall elect one of Section 8.2.4.2(a), (b), (c) or (d) above.

8.2.4.4. The term “Divest” means, with respect to an Acquired Competing Product, the sale, exclusive (even with respect to the Concerned Party and its Affiliates) license, or other delegation, assignment or transfer by a Party or its Affiliates of all of their respective Development and Commercialization rights or obligations with respect to such compound or product to a Third Party without the retention or reservation of any commercialization interest or participation rights (other than solely an economic interest or the right to enforce customary terms and conditions contained in the relevant agreements effectuating such divestiture, including rights of access and review in connection therewith).

Investment Decision milestone payment shall be due in full (even if a Product does not meet the Candidate Drug criteria set forth in the applicable Development Plan) if AstraZeneca decides to select such Product for Candidate Drug Investment Decision.

9.4.2. Satisfaction of Technical Candidate Drug Criteria Without [***]. For each Collaboration Product, in the event that such Product meets the Technical Candidate Drug Criteria established in accordance with Section 3.2.5.2(c)(iii) and included in the Collaboration Product Development Plan but AstraZeneca nonetheless determines not to select such Product for [***], then the [***] milestone shall be due and payable to Pieris but shall be [***] Dollars ($[***]). AstraZeneca’s decision not to select such Product (i.e., either the Lead Candidate or any Back-Up Hit of such Product) meeting the Technical Candidate Drug Criteria for [***] within [***] ([***]) months after the Lead Candidate or any Back-Up Hit of such Product first met such Technical Candidate Drug Criteria, shall be deemed a termination of such Product by AstraZeneca for convenience under Section 14.2.3. If within such [***] ([***]) month period AstraZeneca does make a [***] with respect to the Product (i.e., either the Lead Candidate or any Back-Up Hit of such Product), AstraZeneca shall pay the applicable [***] milestone less [***] Dollars ($[***]) already paid pursuant to the first sentence of this Section 9.4.2. For avoidance of doubt, however, AstraZeneca must at all times continue to use Commercially Reasonable Efforts to Develop such Product. By way of example and for clarity, if AstraZeneca initially chooses not to make a [***] in order to generate more data regarding the Product and to reconsider, then the initial decision shall not be deemed a termination for convenience.

9.4.3. EU Milestones. The “MAA filing in the EU” milestone shall be deemed met with respect to each Product when AstraZeneca files an MAA with the EMA or when it files an MAA with any country of the European Union. The “First Commercial Sale in the EU” shall be deemed upon the First Commercial Sale of each Product in the European Union.

9.7. Additional Royalty Terms.

9.7.1. Royalty Term and Gross Margin Term. The Product Royalties and Gross Margin Payments due under Section 9.6 shall be paid on a Product-by-Product and country-by-country basis and shall be payable for the duration of the Royalty Term or as long as AstraZeneca or its Sublicensee is Commercializing the Product, as applicable. For avoidance of doubt, the Gross Margin Payments and Product Royalties due under Section 9.6 to Pieris where Pieris has exercised a CoDev Option shall be payable for as long as AstraZeneca or its Sublicensee is Commercializing the Product.

9.7.2. Reductions for Third Party Obligations. Subject to Section 9.7.3 below, in the event it would be reasonably necessary to obtain additional licenses to Patents of Third Parties that Cover the active pharmaceutical ingredient (“API”) of the Products, in order to Commercialize the API of any Product (but not, for example, the formulation or associated device, which shall solely be the responsibility of AstraZeneca) (“Additional Third Party Licenses”), AstraZeneca shall negotiate and obtain any such Additional Third Party Licenses but shall not be obligated to do so. AstraZeneca and Pieris shall [***] the costs under such Additional Third Party Licenses and Pieris’ [***] percent ([***]%) share of such costs shall be payable in the form of a reduction, on a country-by-country and Product-by-Product basis, of the Product Royalty that would otherwise be payable by AstraZeneca to Pieris. Pieris’ share of the total costs of such Additional Third Party License shall not reduce Pieris’ Royalty by more than [***] percent ([***]%) of the Product Royalty otherwise due to Pieris in any Calendar Quarter, provided that reductions to Royalty Payments under this Section 9.7.2 not exhausted in one Calendar Quarter may be carried forward to the next Calendar Quarter. For avoidance of doubt, nothing stated herein shall prevent Pieris from seeking licenses to any Intellectual Property Rights or Patent Rights from any Third Party as it deems necessary. Where Pieris is entitled to Gross Margin Payments rather than Product Royalties, Pieris’ [***] percent ([***]%) share of such costs shall be deducted from the Gross Margin Payments otherwise payable to Pieris. Pieris’ share of the total costs of such Additional Third Party License shall not reduce Pieris’ Gross Margin Payment by more than [***] percent ([***]%) of the Gross Margin Payment otherwise due to Pieris in any Calendar Quarter, provided that reductions to Gross Margin Payments under this Section 9.7.2 not exhausted in one Calendar Quarter may be carried forward to the next Calendar Quarter.

9.7.3. Payments to Third Parties in respect of Target IP and Platform IP. Notwithstanding Section 9.7.2 above, Pieris shall be responsible for all costs associated with any license from a Third Party where such license is reasonably necessary, because absent such license, the practice of the Pieris Platform IP and the Pieris Platform Technology in accordance with this Agreement and the Platform Agreement would, in and of itself and irrespective of the Target relevant to such activities or the use of the Anticalin generated through the practice of such IP and

CONFIDENTIAL TREATMENT REQUESTED

Confidential

Platform Technology, infringe a Patent owned or controlled by such Third Party. Notwithstanding Section 9.7.2 above, AstraZeneca shall be responsible for all costs associated with any license from a Third Party to a Patent that generically claims compositions of matter that are specific to the Target or methods of treatment involving the Target in the Field (excluding the [***] Grant-Back Field with respect to the Lead Product) where such license is reasonably necessary because absent such a license, AstraZeneca’s import, export, Manufacture, use, sale or offer for sale of an Anticalin directed to the applicable Designated Target (or the Lead Product Target, as applicable) would infringe such Third Party Patent. Neither AstraZeneca nor Pieris shall enter into any such license on behalf of the other without the other's prior written consent which consent shall not be unreasonably withheld, conditioned or delayed.

9.7.4. Reduction for Biosimilar Competition. If in any Calendar Quarter after entry of a Biosimilar(s) of a Product in a given country there has been a decline of the Net Sales of the applicable Product in such country of more than [***] percent ([***]%) of the Net Sales of such Product in such country achieved in the two consecutive Calendar Quarters immediately prior to such entry in such country, the Royalty Payment payable to Pieris for such Product in such country shall be reduced by [***] percent ([***]%) of the amount otherwise payable hereunder as and from such Calendar Quarter. Notwithstanding the foregoing, in the event of Biosimilar sales that are later enjoined by a court or otherwise halted (such as on the basis of Patent or Regulatory Exclusivity) and the price of the Product returns to the same level as was achieved immediately prior to entry of the Biosimilar, then royalties shall be restored to the level otherwise contemplated under this Agreement. For avoidance of doubt, there shall be no reduction of Gross Margin Payments in connection with this Section 9.7.4.

9.7.5. Royalty Minimum. Notwithstanding the foregoing but subject to Section 9.7.3, in no event will the Product Royalties due to Pieris in a Calendar Quarter be reduced by more than [***] percent ([***]%) of the amount that would otherwise be due hereunder.

9.8. Payment Terms.

9.8.1. Manner of Payment. All payments to be made by AstraZeneca hereunder will be made in Dollars by wire transfer to such bank account as Pieris may designate.

9.8.2. Reports and Royalty Payments. For as long as a Product Royalty or Gross Margin Payment is due to Pieris under this Agreement, AstraZeneca will furnish to Pieris a written report, within [***] ([***]) days after the end of each Calendar Quarter, showing in Dollars, the amount of Net Sales of Products and royalty due, or Gross Margin and Gross Margin Payment due for such Calendar Quarter, as applicable. Product Royalties and/or Gross Margin Payments consistent with the written report provided under this Section 9.8.2 for each Calendar Quarter

CONFIDENTIAL TREATMENT REQUESTED

Confidential

will be due within [***] ([***]) days after the end of each Calendar Quarter. The report will include, at a minimum, the following information for the applicable Calendar Quarter, each listed by Product and by country of sale: (a) the number of units of each Product on which Product Royalty or Gross Margin Payment are owed to Pieris hereunder sold by AstraZeneca or its Affiliates or Sublicensees; (b) the gross amount received for such sales; (c) Net Sales for the Calendar Quarter and Year; (d) the Fully Burdened Manufacturing Cost for such Product; (e) deductions provided for in the definition of Net Sales; and (f) the Product Royalties, Gross Margin Payment, and Sales Milestone Payments owed to Pieris listed by category, as applicable. All such reports will be treated as Confidential Information of AstraZeneca.

9.8.3. Records and Audits. AstraZeneca shall keep complete, true and accurate books and records in accordance with its Accounting Standards in relation to this Agreement, including in relation to Lead Product, AZ Dev Product and CoDev Product Development Costs and Net Sales, Fully Burdened Manufacturing Costs, Gross Margin Payments and Product Royalties. Pieris shall keep complete true and accurate books and records in accordance with Accounting Standards in relation to Lead Product and CoDev Product Development Costs. Each Party will keep such books and records for at least [***] ([***]) years following the Calendar Year to which they pertain. The other Party may, upon written request, cause an internationally-recognized independent accounting firm (the “Auditor”), which is reasonably acceptable to the audited Party, to inspect the relevant records of the audited Party and its Affiliates to verify the payments made or Costs incurred by the audited Party and the related reports, statements and books of accounts, as applicable. Before beginning its audit, the Auditor shall execute an undertaking acceptable to the audited Party by which the Auditor agrees to keep confidential all information reviewed during the audit. The Auditor shall have the right to disclose to the auditing Party only its conclusions regarding any payments owed under this Agreement. The audited Party and its Affiliates shall make their records available for inspection by the Auditor during regular business hours at such place or places where such records are customarily kept, upon receipt of reasonable advance notice from the auditing Party or the Auditor. The records shall be reviewed solely to verify the accuracy of the audited Party's payment or Cost sharing obligations and compliance with the financial terms of this Agreement. Such inspection right shall not be exercised more than once in any Calendar Year and not more frequently than once with respect to records covering any specific period of time. In addition, the auditing Party shall only be entitled to audit the books and records of the audited Party from the [***] ([***]) Calendar Years prior to the Calendar Year in which the audit request is made. The auditing Party agrees to hold in strict confidence all information received and all information learned in the course of any audit or inspection, except to the extent necessary to enforce its rights under this Agreement or to the extent required to comply with any law, regulation or judicial order. The Auditor shall provide its audit report and basis for any determination to the audited Party at the time such report is provided to the auditing Party before it is considered final. In the event that the final

CONFIDENTIAL TREATMENT REQUESTED

Confidential

result of the inspection reveals an undisputed underpayment or overpayment by either Party, the underpaid or overpaid amount shall be settled promptly. The auditing Party shall pay for such inspections, as well as its expenses associated with enforcing its rights with respect to any payments hereunder. In addition, if an underpayment of more than [***] percent ([***]%) of the total payments due hereunder for the applicable year is discovered, the fees and expenses charged by the Auditor shall be paid by the audited Party.

9.8.4. Currency Exchange. The amounts due to Pieris under this Agreement will be expressed in US Dollars. When conversion of payments from any foreign currency is required to be undertaken by AstraZeneca, the US Dollar equivalent shall be calculated using AstraZeneca’s, its Affiliates’ or Sublicensee’s standard conversion methodology consistent with relevant GAAP.

9.8.5. Taxes.

9.8.5.1. The royalties, milestones and other amounts payable by AstraZeneca to Pieris pursuant to this Agreement (“Payments”) shall not be reduced on account of taxes unless required by Applicable Laws. Pieris alone shall be responsible for paying any and all taxes (other than withholding taxes required by Applicable Law to be paid by AstraZeneca) levied on account of, or measured in whole or in part by reference to, any Payments it receives. AstraZeneca shall deduct or withhold from the Payments any taxes that it is required by Applicable Laws to deduct or withhold. If, however, Pieris is entitled under any applicable tax treaty to a reduction of rate of, or the elimination of, applicable withholding tax, it may deliver to AstraZeneca or the appropriate Governmental Authority (with the assistance of AstraZeneca to the extent that this is reasonably required and is expressly requested in writing) the prescribed forms necessary to reduce the applicable rate of withholding or to relieve AstraZeneca of its obligation to withhold tax, and AstraZeneca shall apply the reduced rate of withholding, or dispense with withholding, as the case may be, provided that AstraZeneca has received evidence, in a form reasonably satisfactory to AstraZeneca, of Pieris' delivery of all applicable forms at least fifteen (15) Business Days prior to the time that the Payments are due. If AstraZeneca withholds any taxes from the Payments while Pieris is entitled under any applicable tax treaty to a reduction of the rate of, or the elimination of, applicable withholding tax, AstraZeneca shall cooperate with Pieris with respect to any documentation required by the appropriate Governmental Authority or reasonably requested by Pieris to secure a reduction of the rate of, or the elimination of, the applicable taxes withheld.

9.8.5.2. Notwithstanding anything to the contrary contained in this Agreement, the following shall apply with respect to Indirect Taxes: All payments are stated exclusive of Indirect Taxes. If any Indirect Taxes are

CONFIDENTIAL TREATMENT REQUESTED

Confidential

chargeable in respect of any payments, AstraZeneca shall pay such Indirect Taxes at the applicable rate in respect of any such payments following the receipt, where applicable, of an Indirect Taxes invoice issued in the appropriate form by Pieris in respect of those payments, such Indirect Taxes to be payable on the due date of the payment of the payments to which such Indirect Taxes relate or at the time such Indirect Taxes are required to be collected by Pieris, in the case of payment of Indirect Taxes to Pieris. The Parties shall issue invoices for all goods and services supplied under this Agreement consistent with Indirect Tax requirements, and to the extent any invoice is not initially issued in an appropriate form, AstraZeneca shall promptly inform Pieris and shall cooperate with Pieris to provide such information or assistance as may be necessary to enable the issuance of such invoice consistent with Indirect Tax requirements.

9.8.6. Blocked Payments. In the event that, by reason of Applicable Law in any country, it becomes impossible or illegal for AstraZeneca to transfer, or have transferred on its behalf, payments owed to Pieris hereunder, AstraZeneca will promptly notify Pieris of the conditions preventing such transfer and such payments will be deposited in local currency in the relevant country to the credit of the Pieris in a recognized banking institution designated by the Pieris or, if none is designated by Pieris within a period [***] ([***]) days, in a recognized banking institution selected by the AstraZeneca, as the case may be, and identified in a written notice given to the other Party.

9.8.7. Interest Due. AstraZeneca will pay Pieris interest on any undisputed payments that are not paid on or before the date such payments are due under this Agreement at a rate of [***] percent ([***]%) above LIBOR per annum or the maximum applicable legal rate, if less, calculated on the total number of days such payment is delinquent.

AstraZeneca shall also notify Pieris in writing (which may be via email) promptly if AstraZeneca files any Patents within the AstraZeneca Background Improvement IP whose initially filed claims Cover a Product at the time of filing.

10.4.4.2. Dropped Key IP. In the event that AstraZeneca elects not to Prosecute and Maintain (or continue to Prosecute and Maintain, including filing a Patent claiming priority to a Patent prior to its issuance), any Patent within the Lead Product IP, Collaboration Product IP, or Grantback IP anywhere in the world, AstraZeneca will notify Pieris at least sixty (60) days before any such Patent would become abandoned, no longer available or otherwise forfeited, and Pieris will have the right (but not the obligation), at Pieris’ sole discretion to Prosecute and Maintain such Patent worldwide in the names of both AstraZeneca and Pieris at Pieris’ sole cost (which right will include the right to file additional Patents claiming priority to such Patent). With respect to any Patents within the Key IP other than Patents within the Lead Product IP, Collaboration Product IP, or Grantback IP, AstraZeneca shall offer Pieris the same notifications and rights set forth in the first sentence of this Section 10.4.4.1 to the extent that (i) such Patent Covers a therapeutic method of use of the applicable Product and that such Patent as filed contains at least one (1) claim specific to the use of Anticalin proteins (lipocalin muteins) in the Respiratory Field, or (ii) such Patent relates solely to one or more Product(s) and not to other AstraZeneca products.

10.4.5. Other Anticalin Patents Against a Target. At any time after the initial filing of a provisional or non-provisional Collaboration Product Patent with respect to a given Product, Pieris may file for Patent protection with respect to any Anticalin protein described in Section 2.4.

Product Patent. For clarity, Pieris shall own and fully control such Patents, AstraZeneca shall not have a license to such Patents, and such Patents shall not be considered Pieris IP, Arising IP, or Collaboration Product IP. Pieris shall provide written notice, together with the filing number, to AstraZeneca as soon as reasonably possible if it files any such Patent and Pieris shall also inform AstraZeneca in writing [***] ([***]) [***] before any such Patent is granted in the United States.

10.4.6. Patent Miscellaneous. Each Party hereby agrees: (a) to use commercially reasonable efforts to make its employees, agents and consultants reasonably available to the other Party (or to the other Party’s authorized attorneys, agents or representatives), to the extent reasonably necessary to enable such Party to undertake any Prosecution and Maintenance described herein; and (b) to reasonably cooperate in any such Prosecution and Maintenance by the other Party

10.4.7. German Act on Employee Inventions. Where applicable, Pieris will be responsible for remuneration of inventors who are Pieris employees in accordance with the German Act on Employee Inventions with respect to the Lead Product Patents, Collaboration Product Patents, Pieris Platform Patents, Pieris Platform Improvement Patents, Co-Invented Arising Patents, and Co-Invented AstraZeneca Background Improvement Patents.

10.5. CREATE Act. Neither party shall invoke the Cooperative Research and Technology Enhancement Act (“CREATE Act”) in connection with the Prosecution or Maintenance of any Pieris Platform IP, Pieris Platform Improvement IP, AstraZeneca Background IP or Key IP without the prior written consent of the other Party.

10.6. Defense.

10.6.1. 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 AstraZeneca, 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.

10.6.2. If a Third Party asserts that a Patent owned by or licensed to it are infringed by the development, manufacture, use, importation, offer for sale or sale of a Lead Product or Collaboration Product by AstraZeneca or its Affiliates (or by Pieris in the case of Co-Development or Co-Commercialization), or that its trade secrets were misappropriated in connection with such activity, then AstraZeneca 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

CONFIDENTIAL TREATMENT REQUESTED

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, AstraZeneca 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 AstraZeneca 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 Patents Controlled by Pieris, or have any impact on activities outside the Field.

10.6.3. If an action for infringement is commenced against Pieris, its licensees or its sublicensees related to Pieris’ conduct of the research program within the scope of the Lead Product Development Plan or a Collaboration Product Development 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 AstraZeneca 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 AstraZeneca and its Affiliates (including any Patents 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.

10.6.4. Notwithstanding Section 10.6.3, if the infringement action against Pieris is the result of its co-Development or co-Commercialization activities with respect to any Product, then it shall be treated as an action under Section 10.6.2 and AstraZeneca shall have the exclusive right and responsibility to resolve any such claim subject to the provisions of that Section.

10.7. Enforcement.

10.7.1. AstraZeneca shall have the full and unrestricted right, but not the obligation, to bring and control an appropriate suit or other action against any person or entity engaged in any infringement action or proceeding to the extent directly relating to Key IP and any Products in the Field, but excluding the [***] Grant-Back Field with respect to the Lead Product (“Infringement Action”), in its own name and entirely under its own direction and control. In the event that AstraZeneca does not wish to enforce such Patents against such a potential infringer, then AstraZeneca shall deliver prompt written notice thereof to Pieris. If AstraZeneca requests so, Pieris shall reasonably cooperate with AstraZeneca in the planning and execution of any such action to enforce such Patents (including the obligation to be named or joined as a party in a lawsuit, as applicable). Notwithstanding the foregoing, if AstraZeneca does not either initiate such an Infringement Action or grant adequate rights and licenses to such Third Party within one hundred twenty (120) days after AstraZeneca’s receipt of a notice of infringement (or sooner if any deadlines require

action prior to such one hundred and twenty (120) days) and the infringement relates to the launch or a threat to launch a Biosimilar version of a Product, then Pieris will have the second right, but not the obligation, to initiate such Infringement Action, but solely with respect to any Patent Right within the Pieris IP, Lead Product IP, Collaboration Product IP and Grantback IP. All monies recovered upon the final judgment or settlement of any such suit or action to enforce such Patents subtracting any costs that the Parties bore in connection with such suit or action, shall be treated as Net Sales to the extent such monies recovered are designated as lost profits, and shall otherwise be divided between the Parties with [***] percent ([***]%) paid by the enforcing Party to the non-enforcing Party and [***] percent ([***]%) retained by enforcing Party.

10.7.2. For avoidance of doubt, AstraZeneca shall not have the right to assert or enforce any other Patents owned or Controlled by Pieris under this Agreement, such as the Patent Rights within the Pieris Platform IP or Pieris Platform Improvement IP, against a Third Party under any circumstances and Pieris shall not be under any obligation to enforce such Patent Rights.

10.7.3. Notwithstanding Section 10.7.1, Pieris shall have the right, but not the obligation, to bring and control an appropriate suit or other action against any person or entity engaged in any infringement action or proceeding under the Pieris IP (including the Lead Product IP) and Arising IP to the extent directly relating to a Lead Product Patent and to the Lead Product in the [***] Grant-Back Field (“[***] Infringement Action”), in its own name and entirely under its own direction and control with the prior written consent of AstraZeneca. If AstraZeneca provides such consent, the Parties shall reasonably cooperate with in the planning and execution of any such action to enforce such Patents (including the obligation to be named or joined as a party in a lawsuit, as applicable). All monies recovered upon the final judgment or settlement of any such suit or action to enforce such Patents subtracting any costs that Pieris or AstraZeneca bore in connection with such suit shall be retained in their entirety by Pieris. Even in the event that Pieris does not wish to bring an action under this Section 10.7.3, AstraZeneca still shall not have the right to bring or control any [***] Infringement Action. For avoidance of doubt, nothing in this Section shall restrict Pieris from enforcing any other Patent or Intellectual Property Rights against any Third Party in the [***] Grant-Back Field (including any Patents filed by Pieris as described in Section 10.3).

10.8. Common Interest Disclosures. With regard to any information or opinions disclosed pursuant to this Agreement by one Party to each other regarding intellectual property and/or technology owned by Third Parties, the Parties agree that they have a common legal interest in determining whether, and to what extent, Third Party intellectual property rights may affect the conduct of the Development Plans and/or Lead Product and/or Collaboration Products, and have a further common legal interest in defending against any actual or prospective Third Party claims based on allegations of misuse or infringement of intellectual property rights relating to the conduct of the Development Plans and/or Lead Product and/or Collaboration Products. Accordingly, the Parties agree that all such information and materials obtained by Pieris and AstraZeneca 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. Neither Party shall have the authority to waive any privilege or immunity on behalf of the other Party without such other Party’s prior written consent, nor shall the waiver of privilege or immunity resulting from the conduct of one Party be deemed to apply against any other Party.

10.9. Patent Term Extensions. AstraZeneca shall use commercially reasonable efforts to obtain all available patent term extensions, adjustments or restorations, or supplementary protection certificates (“SPCs”, and together with patent term extensions, adjustments and restorations, “Patent Term Extensions”) for each Product with respect to the AstraZeneca Background IP and Key IP. Pieris shall execute such authorizations and other documents and take such other actions as may be reasonably requested by AstraZeneca to obtain such Patent Term Extensions. All filings for such Patent Term Extensions shall be made by AstraZeneca; provided, that in the event that AstraZeneca elects not to file for a Patent Term Extension, AstraZeneca shall (a) promptly inform Pieris of its intention not to file and (b) grant Pieris the right to file for such Patent Term Extension. Each Party shall execute such authorizations and other documents and take such other actions as may be reasonably requested by the other Party to obtain such extensions. Pieris shall not and shall procure that its Affiliates and licensees shall not apply for a Patent Term Extension for PRS-060 in the [***] Grant-Back Field without AstraZeneca's prior written consent. The Parties shall cooperate with each other in gaining patent term restorations, extensions and/or SPCs wherever applicable to such Patents. For avoidance of doubt, AstraZeneca shall not be permitted to apply for any Patent Term Extensions using the Pieris Platform IP without the prior written consent of Pieris.

13.3. Notice of Claim. All indemnification claims provided for in Section 13.1 and Section 13.2 will be made solely by such Party to this Agreement (the “Indemnified Party”). The Indemnified Party will give the indemnifying Party prompt written notice (an “Indemnification Claim Notice”) of any Losses or the discovery of any fact upon which the Indemnified Party intends to base a request for indemnification under Section 13.1 or Section 13.2, but in no event will the indemnifying Party be liable for any Losses to the extent such Losses result from any delay in providing such notice. Each Indemnification Claim Notice must contain a description of the claim and the nature and amount of such Loss (to the extent that the nature and amount of such Loss is known at such time). The Indemnified Party will furnish promptly to the indemnifying Party copies of all papers and official documents received in respect of any Losses and Third Party Claims.

13.4. Defense, Settlement, Cooperation and Expenses.

13.4.1. Control of Defense. At its option, the indemnifying Party may assume the defense of any Third Party Claim by giving written notice to the Indemnified Party within thirty (30) days after the indemnifying Party’s receipt of an Indemnification Claim Notice. The assumption of the defense of a Third Party Claim by the indemnifying Party will not be construed as an acknowledgment that the indemnifying Party is liable to indemnify the Indemnified Party in respect of the Third Party Claim, nor will it constitute a waiver by the indemnifying Party of any defenses it may assert against the Indemnified Party’s claim for indemnification. Upon assuming the defense of a Third Party Claim, the indemnifying Party may appoint as lead counsel in the defense of the Third Party Claim any legal counsel selected by the indemnifying Party. In the event the indemnifying Party assumes the defense of a Third Party Claim, the Indemnified Party will as soon as reasonably possible deliver to the indemnifying Party all original notices and documents (including court papers) received by the Indemnified Party in connection with the Third Party Claim. Should the indemnifying Party assume the defense of a Third Party Claim, except as provided in this Section 13.4.1, the Indemnified Party will be responsible for the legal costs or expenses subsequently incurred by such Indemnified Party in connection with the analysis, defense or settlement of the Third Party Claim.

13.4.2. Right to Participate in Defense. Without limiting Section 13.4.1, any Indemnified Party will be entitled to participate in, but not control, the defense of such Third Party Claim and to employ counsel of its choice for such purpose; provided, however, that such employment will be at the Indemnified Party’s own cost and expense unless (a) the employment thereof has been specifically authorized by the indemnifying Party in writing, (b) the indemnifying Party has failed to assume the defense and employ counsel in accordance with Section 13.4.1 (in which case the Indemnified Party will control the defense), or (c) the interests of the Indemnified Party and the indemnifying Party with respect to such Third Party Claim are sufficiently adverse to prohibit the representation by the same counsel of both Parties under Applicable Law, ethical rules or equitable principles in which case the

107

CONFIDENTIAL TREATMENT REQUESTED

indemnifying Party will be responsible for any such costs and expenses of counsel for the Indemnified Party.

13.4.3. Settlement. With respect to any Third Party Claims relating solely to the payment of money damages in connection with a Third Party Claim and that will not admit liability or violation of Applicable Law on the part of the Indemnified Party or result in the Indemnified Party’s becoming subject to injunctive or other relief or otherwise adversely affecting the business of the Indemnified Party in any manner (such as granting a license or admitting the invalidity of a Patent Controlled by an Indemnified Party), and as to which the indemnifying Party will have acknowledged in writing the obligation to indemnify the Indemnified Party hereunder, the indemnifying Party will have the sole right to consent to the entry of any judgment, enter into any settlement or otherwise dispose of such Loss, on such terms as the indemnifying Party, in its sole discretion, will deem appropriate. With respect to all other Losses in connection with Third Party Claims, where the indemnifying Party has assumed the defense of the Third Party Claim in accordance with Section 13.4.1, the indemnifying Party will have authority to consent to the entry of any judgment, enter into any settlement or otherwise dispose of such Loss provided it obtains the prior written consent of the Indemnified Party (which consent will not be unreasonably withheld). The indemnifying Party will not be liable for any settlement, consent to entry of judgment, or other disposition of a Loss by an Indemnified Party that is reached without the written consent of the indemnifying Party. Regardless of whether the indemnifying Party chooses to defend or prosecute any Third Party Claim, no Indemnified Party will admit any liability with respect to or settle, compromise or discharge, any Third Party Claim without the prior written consent of the indemnifying Party, such consent not to be unreasonably withheld.

13.4.4. Cooperation. Regardless of whether the indemnifying Party chooses to defend or prosecute any Third Party Claim, the Indemnified Party will, and will cause each other Indemnified Party to, cooperate in the defense or prosecution thereof and will furnish such records, information and testimony, provide such witnesses and attend such conferences, discovery proceedings, hearings, trials and appeals as may be reasonably requested in connection therewith. Such cooperation will include access during normal business hours afforded to indemnifying Party to, and reasonable retention by the Indemnified Party of, records and information that are reasonably relevant to such Third Party Claim, and making Indemnified Parties and other employees and agents available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder, and the indemnifying Party will reimburse the Indemnified Party for all its reasonable Out-of-Pocket Costs and expenses in connection therewith.

13.4.5. Costs and Expenses. Except as provided above in this Section 13.4, the costs and expenses, including attorneys’ fees and expenses, incurred by the Indemnified Party in connection with any claim will be reimbursed on a Calendar Quarter basis by the indemnifying Party, without prejudice to the indemnifying

Any such termination shall become effective at the end of such one hundred and eighty (180) day (or thirty (30) day with respect to payment breach) period if, prior to the expiration of the one hundred and eighty (180) day (or thirty (30) day, as applicable) period, the breaching Party has not cured any such breach or default. In the event that the breach is not susceptible to cure during such one hundred and eighty (180) day period, then, upon written notice to the non-breaching Party during the initial one hundred and eighty (180) day period, the breaching Party may have additional time, not to exceed another one hundred and eighty (180) days to cure such breach. If the allegedly breaching Party disputes the breach and provides written notice of that dispute to the other Party, the matter shall be addressed under the dispute resolution provisions in Section 15.1, and the notifying Party may not terminate this Agreement until it has been finally determined under Section 15.1.4, that the Agreement was materially breached as described above and the breaching Party does not cure the breach within sixty (60) days of the arbitration award under Section 15.1.4 below.

14.3. Effects of Termination.

14.3.1. Effects of Termination. In the event of any termination of this Agreement in its entirety or with respect to any given Product or given country other than termination (i) by AstraZeneca for Pieris’ material breach under Section 14.2.1, (ii) by AstraZeneca due to Pieris’ insolvency under Section 14.2.4, or (iii) under Section 14.2.2 (termination by mutual agreement), then the following shall apply:

14.3.1.1. At Pieris’ request, AstraZeneca will return to Pieris or destroy (and certify such destruction to Pieris), at Pieris’ option, all Pieris’ Confidential Information related to the terminated Product(s) and Pieris Know-How related to the terminated Product(s) (provided that AstraZeneca shall be entitled to retain one (1) copy for archival and compliance purposes, and as required by Applicable Law or regulatory requirement). At AstraZeneca’s request, subject to Section 14.3.1.6, Pieris will return to AstraZeneca or destroy (and certify such destruction to AstraZeneca), at AstraZeneca’s option, all other AstraZeneca Confidential Information related to the terminated Product(s) and all other AstraZeneca Know-How related to the terminated Product(s) (provided that Pieris shall be entitled to retain one (1) copy for archival and compliance purposes, and as required by Applicable Law or regulatory requirement).

14.3.1.2. Pieris shall have the right to acquire some or all of the available inventory of the terminated Product, as requested by Pieris, in the possession of AstraZeneca and its Affiliates as of the date of such termination, provided that, if Pieris so acquires any or all such inventory, Pieris shall reimburse AstraZeneca the cost incurred by AstraZeneca for such inventory and if Pieris does not purchase such inventory AstraZeneca shall be entitled to continue selling any such inventory for [***] ([***]) months following the effective date of termination.

14.3.1.3. All licenses and sublicenses granted by Pieris to AstraZeneca hereunder shall terminate, provided however that they will continue solely to enable AstraZeneca to (i) complete sales of Products for any purchase orders that were in place prior to the effective date of termination and (ii) sell off any existing inventory of Products pursuant to Section 14.3.1.2; thereafter, AstraZeneca will discontinue Commercialization of the applicable Product.

14.3.1.4. To the extent requested by Pieris, AstraZeneca shall enter into an agreement whereby AstraZeneca assigns its rights to the Lead Product Patents and Collaboration Product Patents (including all Patents therein) to Pieris and grants an exclusive (sub)license to Pieris, under AstraZeneca Contributed IP and Arising IP reasonably necessary to further Develop, Manufacture and Commercialize the terminated Products

115

Confidential

(including any Patent Rights or Intellectual Property Rights included in the AstraZeneca Contributed IP or Arising IP related to the device for such terminated Product) on reasonable commercial terms, including adequate indemnities to be agreed upon. For purposes of this Section 14.3.1, “reasonable commercial terms” means that (i) no upfront or milestone payments shall be due from Pieris to AstraZeneca for such terminated Product, and (ii) any royalties on Net Sales of any terminated Product shall not exceed (a) [***] percent ([***]%) if the effective date of termination for such Product is prior to [***] for such Product, (b) [***] percent ([***]%) if the effective date of termination for such Product is after [***] for such Product but is prior to the [***] for such Product or (c) [***] percent ([***]%) if the effective date of termination for such Product is after the [***] for such Product. Notwithstanding the forgoing, to the extent that the licenses provided under this Section 14.3.1.4 do not include any Intellectual Property rights Covering an inhalation device that is being used for inhaled delivery of the terminated Product, then the royalty rate ceilings set forth under this Section 14.3.1.4 shall be reduced by [***] percent ([***]%). In the event that AstraZeneca has in-licensed Patent Rights from a Third Party specifically pertaining to an inhalation device for use in connection with the terminated Product (“Device In-License”), then the royalty rate ceilings set forth under this Section 14.3.1.4 shall also be reduced by [***] percent ([***]%) and Pieris shall pay the royalties associated with such Device In-License to such Third Party. Pieris shall be responsible for paying any royalties, milestones or other sums which may be due to Third Parties in respect of any Intellectual Property Rights licensed by AstraZeneca to Pieris pursuant to this Section 14.3.1.4. Pieris shall take over responsibility for the Prosecution and Maintenance and shall have sole enforcement rights (with AstraZeneca providing any reasonably requested assistance) of any Patents in the Arising IP and AstraZeneca Background Improvement IP which solely and exclusively Cover the Products.

14.3.1.5. At the request of Pieris, AstraZeneca shall continue all [***] ([***]) [***] and all [***] (including AstraZeneca’s funding or co-funding of such [***]) through Completion of such [***] and completion of such [***].

14.3.1.6. AstraZeneca will, as promptly as practicable, and subject to Pieris’ reasonable assistance and to agreeing reasonable commercial terms pursuant to Section 14.3.1.4, to the extent legally permissible (including to the extent permitted under AstraZeneca’s obligations to Third Parties on the effective date of termination), (i) transfer and assign to Pieris or Pieris’ designee AstraZeneca’s right, title and interest in and to all material governmental or regulatory filings and approvals (including all Marketing Approvals and pricing approvals, and Regulatory Materials, in all cases, specifically and exclusively relating to the

116

Development, Manufacture or Commercialization of the terminated Products, and (ii) transfer to Pieris or Pieris’ designee copies of all material Data, Know-How, Clinical Study data and safety data in AstraZeneca’s possession and Control to the extent specifically related to and required for the research, Development, Manufacture or Commercialization of the terminated Products. In addition, AstraZeneca will appoint Pieris as AstraZeneca’s and/or AstraZeneca’s Affiliates’ agent for all terminated Product-related matters involving Regulatory Authorities until all Marketing Approvals, regulatory approvals and other regulatory filings hereunder have been assigned to Pieris or its designee. In the event of (x) failure to obtain assignment or (y) with respect to regulatory items that would otherwise fall within (i) and (ii) but for such materials not being specifically related to the terminated Products, but nonetheless which are reasonably necessary for the Development, Manufacture or Commercialization of the terminated Products above, in each of (x) and (y) AstraZeneca hereby consents and grants to Pieris the right to access and reference (without any further action required on the part of AstraZeneca, whose authorization to file this consent with any Regulatory Authority is hereby granted) any such item with respect to all terminated Products.

14.3.1.7. If AstraZeneca or its Affiliates are Manufacturing Finished Product with respect to terminated Products on the effective date of termination, at Pieris’ option (which must be exercised in writing to AstraZeneca within [***] ([***]) days of the effective date of termination), AstraZeneca or its Affiliates will use commercially reasonable efforts to supply such Finished Product (including any device if applicable, but solely in the form as such terminated Product was being manufactured by AstraZeneca as of the effective date of termination) to Pieris at AstraZeneca’s Fully Burdened Manufacturing Cost plus [***] percent ([***]%), until the earlier of (i) such time as Pieris has procured or developed its own source of such Finished Product supply, or (ii) t[***] ([***]) months following the effective date of termination. Should Pieris not be able to procure or develop its own source of Finished Product supply within [***] ([***]) months, then the Parties will discuss in good faith a potential extension of supply by AstraZeneca to avoid any supply interruption. The Parties will promptly negotiate a supply and related quality agreement to govern the specific terms and conditions of such supply.

14.3.1.8. If Pieris so requests within [***] ([***]) days of the effective date of termination, the Parties will cooperate, to the extent legally permissible (including to the extent permitted under AstraZeneca’s obligations to Third Parties on the effective date of termination), to assign to Pieris any Third Party agreements that are specific to and exclusively relating to the Development, Manufacture or Commercialization of the

117

terminated products to which AstraZeneca is a party, subject to any required consents of such Third Party.

14.3.1.9. Subject to agreeing to reasonable commercial terms pursuant to Section 14.3.1.4, the Parties will cooperate, to the extent legally permissible (including to the extent permitted under AstraZeneca’s obligations to Third Parties on the effective date of termination), to promptly transfer and assign or exclusively license (or, if applicable, will cause its Affiliates to assign) to Pieris all of AstraZeneca’s (and such Affiliates’) worldwide right, title and interest in and to any registered trademarks or registered internet domain names that are specific to and exclusively used for the terminated Products (it being understood that the foregoing will not include any trademarks or internet domain names that contain the corporate or business name(s) of AstraZeneca or any of its Affiliates or any other products of AstraZeneca or any of its Affiliates).

14.3.1.10. Subject to AstraZeneca’s agreement that it will not incorporate any Intellectual Property Rights, Data or Know-How Controlled by [***] that would be reasonably necessary for Pieris to continue the Development, Manufacture or Commercialization of any terminated Product, AstraZeneca shall not be required to grant a license under or otherwise transfer to Pieris under this Section 14.3.1 any Intellectual Property Rights, Data or Know-How Controlled by [***]. For clarity, AstraZeneca agrees not use any [***] for the Manufacture of any Product. AstraZeneca and its Affiliates (including MedImmune) hereby covenant not to sue (and not to assist Third Parties in suing) Pieris or its Affiliates or Sublicensees alleging infringement or misappropriation of any Intellectual Property Rights (including any claim for Patent infringement) with respect to any terminated Product as it is constituted at the date of termination for any Intellectual Property Rights including Patent Rights Controlled by AstraZeneca and its Affiliates (including MedImmune) at the date of termination or any Patents Controlled by AstraZeneca or its Affiliates after the date of termination to the extent such Patents incorporate Arising IP or AstraZeneca Contributed IP.

14.3.1.11. More generally, the Parties shall cooperate to ensure a smooth and orderly transition of the Product, including any Development, Manufacturing, or Commercialization activities ongoing at the time of termination to Pieris, pursuant to a termination agreement to be negotiated by the Parties within [***] ([***]) months following the termination notice. Such agreement shall be consistent with this Section 14.3.1.

14.3.1.12. For clarity where a Product is sold as part of a Combination Product, Pieris shall only have rights under this Section 14.3.1

with regard to the Product and Pieris shall not be granted any rights with regard to the other active ingredient.

14.3.2. Termination Due to Competing Product.

14.3.2.1. In the event that this Agreement is terminated (i) by Pieris for AstraZeneca’s material breach of the Non-Compete under Section 8.2.3 or (ii) by AstraZeneca for convenience (but not for Clinical Failure) under Section 14.2.3 where within [***] ([***]) [***] of the effective date of such termination, AstraZeneca Develops, Manufactures or Commercializes a Competing Product (excluding any Competing Product of any Acquiror of AstraZeneca) corresponding to the terminated Product (a) beyond [***], (b) beyond [***] in the event that the terminated product had achieved [***] Prior to the effective date of termination or (c) is no longer at [***] (as defined in Section 8.2.3.7) as compared to the [***] of the terminated Product on the effective date of termination, then the following shall apply in addition to the provisions of Section 14.3.1: AstraZeneca will pay the [***] with respect to such Product within [***] ([***]) days of (1) the effective date of the termination of the Agreement by Pieris with respect to the applicable Product as described in this Section 14.3.2.1(i) above, or (2) AstraZeneca’s initiation of [***] within [***] ([***]) [***] of termination of the corresponding Product by AstraZeneca for convenience as described in this Section 14.3.2.1(ii)(a)-(c) above. In the event that a terminated Product is terminated following [***] but before [***], the [***] shall be the [***] in the [***] for that terminated Product. By way of example, if the Lead Product is terminated under this Section 14.3.2.1 during a [***] and Pieris has not exercised the [***] (i.e., has exercised the [***] Split Option, [***] Cap Option, or has not exercised its CoDev Option), then AstraZeneca shall pay Pieris [***] Dollars ($[***]). In the event that a terminated Product is terminated following [***] but before [***] of such terminated Product, the [***] shall be the [***] in the [***] for that terminated Product. By way of example, if the Lead Product is terminated under this Section 14.3.2.1 after [***] and Pieris has not exercised the [***] (i.e., has exercised the [***] Split Option, [***] Cap Option, or has not exercised its CoDev Option) then AstraZeneca shall pay Pieris [***] Dollars ($[***]). Once any such [***] has been paid no further sums will be due under this Section.

14.3.2.2. For the avoidance of doubt, Section 14.3.2.1 shall not apply if AstraZeneca terminated a Product due to Clinical Failure.

14.3.3. For Material Breach or Insolvency. In the event that AstraZeneca terminates this Agreement as a result of Pieris’ material breach under Section

14.2.1, due to Pieris’ insolvency under Section 14.2.4, or as a result of Pieris's Patent challenge under Section 14.2.5.2, then the following terms shall apply:

At the Disclosing Party's request, the Receiving Party will return to the Disclosing Party or destroy (and certify such destruction to the Disclosing Party), at Disclosing Party’s option, all Disclosing Party’s Confidential Information related to the terminated Product(s) (provided that the Receiving Party shall be entitled to retain one (1) copy for archival and compliance purposes, and as required by Applicable Law or regulatory requirement).

14.3.3.2. All Development, Manufacture and Commercialization of such terminated Product by the Parties shall immediately cease;

14.3.3.3. The licenses granted by each Party to the other with respect to the terminated Product shall immediately terminate; and

Each Party agrees that the other Party, as licensee of such rights under this Agreement, shall retain and may fully exercise all of its rights and elections under the Bankruptcy Code. In the event of the commencement of a bankruptcy proceeding by or against a Party under the Bankruptcy Code (the “Insolvent Party”), the other Party shall be entitled to a complete duplicate of (or complete access to, as appropriate) any intellectual property and Know-How licensed to such Party under this Agreement and held by such first Party and its successors and assigns (and all embodiments of such intellectual property and Know-How), provided that, a Party shall not be required to provide any duplicate copies and embodiments of such intellectual property or Know-How to the other Party so long it has already provided such intellectual property and Know-How it is required to provide to under this Agreement, and, if not already in its possession, shall be promptly delivered to it (a) upon any such commencement of a bankruptcy proceeding upon its written request therefore, unless the Insolvent Party continues to perform all of its obligations under this Agreement, or (b) if not delivered or granted under (a) above, following the rejection of this Agreement by or on behalf of the Insolvent Party upon written request therefore by the other Party.

15.1.3. Request for Arbitration. If after negotiating in good faith, the Parties fail after good faith discussions undertaken within reasonable promptness, to reach an amicable agreement within ninety (90) days, then either Party may upon written notice to the other submit to binding arbitration pursuant to Section 15.1.4 below; provided that any dispute within the JSC’s decision-making authority shall be resolved in accordance with Section 3.2.5, rather than arbitration. No statements made by either Party during such discussions will be used by the other Party or

15.1.4. Arbitration.

15.1.4.1. Subject to Section 15.2, any dispute, claim or controversy arising from or related in any way to this Agreement or the interpretation, application, breach, termination or validity thereof, including any claim of inducement of this Agreement by fraud or otherwise, not resolved under the provisions of Section 15.1.1, will be resolved by final and binding arbitration conducted in accordance with the terms of this Section 15.1.4.1. The arbitration will be held in New York, New York, USA according to Rules of Arbitration of the ICC. The arbitration will be conducted by a panel of three (3) arbitrators with significant experience in the pharmaceutical industry, unless otherwise agreed by the Parties, appointed in accordance with applicable ICC rules. Any arbitration herewith will be conducted in the English language to the maximum extent possible. The arbitrators will render a written decision no later than [***] following the selection of the arbitrators, including a basis for any damages awarded and a statement of how the damages were calculated. Any award will be promptly paid in U.S. dollars free of any tax, deduction or offset. Each Party agrees to abide by the award rendered in any arbitration conducted pursuant to this Section 15.1.4. With respect to money damages, nothing contained herein will be construed to permit the arbitrator or any court or any other forum to award punitive or exemplary damages, except in the case of breach of Section 11.1. By entering into this agreement to arbitrate, the Parties expressly waive any claim for punitive or exemplary damages, except in the case of breach of Section 11.1. Each Party will pay its legal fees and costs related to the arbitration (including witness and expert fees). Judgment on the award so rendered will be final and may be entered in any court having jurisdiction thereof.

15.1.4.2. EACH PARTY HERETO WAIVES ITS RIGHT TO TRIAL OF ANY ISSUE BY JURY. EACH PARTY HERETO WAIVES ANY CLAIM FOR ATTORNEYS' FEES AND COSTS AND PREJUDGMENT INTEREST FROM THE OTHER.

15.1.5. Court Actions. Nothing contained in this Agreement will deny either Party the right to seek injunctive or other equitable relief from a court of competent jurisdiction in the context of a bona fide emergency or prospective irreparable harm, and such an action may be filed and maintained notwithstanding any ongoing dispute resolution discussions or arbitration proceeding. In addition, either Party may bring an action in any court of competent jurisdiction to resolve disputes pertaining to the validity, construction, scope, enforceability, infringement or other violations of patents or other proprietary or Intellectual Property Rights, and no such claim will be subject to arbitration pursuant to Section 15.1.4.

15.2. Governing Law, Jurisdiction, Equitable Relief, Losses, and Remedies.

15.2.1. This Agreement will be governed by and construed and enforced in accordance with the laws of the State of New York, USA, without reference to any rules of conflicts of laws. For clarification, any dispute relating to the scope, validity, enforceability or infringement of any Patents will be governed by and construed and enforced in accordance with the patent laws of the applicable jurisdiction.

15.2.2. Each Party acknowledges and agrees that the restrictions set forth in Section 8.2 of this Agreement are reasonable and necessary to protect the legitimate interests of the other Party and that the other Party would not have entered into this Agreement in the absence of such restrictions, and that any breach or threatened breach of any of these provisions will probably result in irreparable injury to the other Party for which there will be no adequate remedy at law. In the event of a breach or threatened breach of any such provision, each Party will be authorized and entitled to obtain from any court of competent jurisdiction equitable relief, whether preliminary or permanent, specific performance and an equitable accounting of all earnings, profits and other benefits arising from such breach, which rights will be cumulative and in addition to any other rights or remedies to which such Party may be entitled in law or equity. Each Party agrees to waive any requirement that the other Party (a) post a bond or other security as a condition for obtaining any such relief, and (b) show irreparable harm, balancing of harms, consideration of the public interest or inadequacy of monetary damages as a remedy. Nothing in this Section 15.2.2 is intended, or should be construed, to limit a Party's rights to equitable relief or any other remedy for a breach of any other provision of this Agreement. Except for (i) any amount awarded to be paid by one Party to the other by the panel of arbitrators in a final and binding arbitration proceeding adjudicated under Section 15.1.4.1, and (ii) any offset of undisputed but unpaid amounts under this Agreement, neither Party will have the right to set off any amount it is owed or believes it is owed against payments due or payable to the other Party under this Agreement.

15.2.3. Neither Party will be entitled to recover any Losses relating to any matter arising under one provision of this Agreement to the extent that such Party has already recovered Losses with respect to such matter pursuant to other provisions of this Agreement (including recoveries under Section 13) or the Platform Agreement.

15.3. Antitrust Filing.

15.3.1. Each Party agrees to prepare and make or cause to be prepared and made appropriate filings under the HSR Act and any other antitrust requirements relating to this Agreement and the transactions contemplated under this Agreement within [***] ([***]) Business Days after the Execution Date. Each of the Parties agrees to cooperate in the antitrust clearance process, including by furnishing to the other Party such necessary information and reasonable assistance as the other Party may request in connection with its preparation of any filing or submission that is

123

CONFIDENTIAL TREATMENT REQUESTED

Confidential

necessary under the HSR Act and other antitrust requirements, and to furnish promptly with the United States Federal Trade Commission (“FTC”), the Antitrust Division of the United States Department of Justice (“DOJ”) and any other antitrust authority, any information reasonably requested by them in connection with such filings. Each Party shall furnish copies (subject to reasonable redactions for privilege or confidentiality concerns) of, and shall otherwise keep the other Party apprised of the status of any communications with, and any inquiries or requests for additional information from, the FTC, DOJ and any other antitrust authority, and shall comply promptly with any such inquiry or request. Each Party shall give the other Party the opportunity to review in advance, and shall consider in good faith the other Party’s reasonable comments in connection with any proposed filing or communication with the FTC, DOJ or any other antitrust authority. Each Party shall consult with the other Party, to the extent practicable, in advance of participating in any substantive meeting or discussion with the FTC, the DOJ or any other antitrust authority with respect to any filings, investigation or inquiry and, to the extent permitted by such antitrust authority, give the other Party to the opportunity to attend and participate in such meeting or discussion. Neither Party shall withdraw its filing under the HSR Act or agree to delay the Effective Date without the prior written consent of the other Party. The Parties’ rights and obligations hereunder apply only in so far as they relate to the Agreement and to the transactions contemplated under the Agreement.

15.3.2. Each Party shall use commercially reasonable efforts to obtain the expiration or early termination of the HSR Act and any other clearance required under other antitrust requirements relating to the Agreement and the transactions contemplated under the Agreement. Commercially reasonable efforts as used in this Section 15.3.2 will not include proposing, negotiating, committing to and effecting, by consent decree, hold separate order, or otherwise, (a) the sale, divestiture, disposition, licensing or sublicensing of any of a Party’s or its Affiliates’ assets, properties or businesses, (b) behavioral limitations, conduct restrictions or commitments with respect to such assets, properties or business, or of any of the rights or obligations of a Party under this Agreement, or (c) defending through litigation any claim asserted in court by any party that would restrain, prevent or delay the Effective Date.

15.3.3. Other than the provisions of Section 14.1, Section 11, and Section 15 which shall apply as of the Execution Date, the rights and obligations of the Parties under this Agreement will not become effective until the waiting period under the HSR Act has been terminated or expired, or any other timeline required by another antitrust authority and there is no proceeding, order, injunction or judgment relating thereto, pending before any governmental authority in which it is sought to restrain or prohibit the transaction(s) contemplated hereby. Upon the occurrence of the Effective Date, all other provisions of this Agreement shall become effective automatically without the need for further action by the Parties.

15.3.4. AstraZeneca shall be responsible for the filing fee related to any initial filing required by the HSR Act. Thereafter, each Party shall be responsible for its fees and costs associated with the preparation and submission of any required notification and report form under the HSR Act (or to any other antitrust authority), and the provision of any supplemental information to the FTC, DOJ or other antitrust authority, including any legal fees incurred by such Party in connection with such Party’s obligations pursuant to this Section 15.3.

15.4. Assignments and Successors. Neither this Agreement nor any obligation of a Party hereunder may be assigned by either Party without the consent of the other, except that each Party may assign this Agreement and the rights, obligations and interests of such Party, in whole or in part, without the other Party’s consent, to any of its Affiliates for as long as such entity remains an Affiliate, to any purchaser of all or substantially all of its assets to which this Agreement or relevant part relates or to any successor corporation resulting from any merger, consolidation, share exchange or other similar transaction. In addition, Pieris may assign or transfer its rights to receive payments under this Agreement (but no liabilities), without AstraZeneca’s consent, to an Affiliate or to a Third Party in connection with a payment factoring transaction; provided, however, that Pieris will provide AstraZeneca advance notice of any such proposed payment factoring transaction giving AstraZeneca a reasonable opportunity to provides comments (which Pieris will consider in good faith). Upon Pieris’ request, AstraZeneca shall provide royalty reports described under Section 9.8 and direct payments described under Section 8.2.4.3 to such Third Party and such provision and direction shall satisfy any obligation to provide such a payment or report to Pieris. Any purported assignment or transfer made in contravention of this Section 15.3 will be null and void.

15.5. Acquiror IP. Notwithstanding anything to the contrary in this Agreement, in the event of a Change of Control involving either Party or its business after the Execution Date (the Third Party acquiring such Party or its business being the Acquiror), whether by merger, asset purchase or otherwise, as to any such Acquiror, the non-acquired Party shall not obtain rights, licenses, options or access to any Intellectual Property Rights or Know-How, product candidates or products that are held by the Acquiror or any Affiliate of the Acquiror that becomes an Affiliate of the acquired Party as a result of such acquisition (but excluding the acquired Party itself), that were not generated through any use or access to the Intellectual Property Rights or Know-How of the acquired Party, or that are not used by the acquired Party in connection with a Product under this Agreement.

15.6. Change of Control Involving Pieris.

15.6.1. Notice. Pieris will provide written notice (“COC Notice”) to AstraZeneca within [***] ([***]) [***] following the closing of a Change of Control involving Pieris, and such notice will identify the Third Party acquiring company (the “COC Acquiror”).

15.6.2. Effect on Pieris Co-Development and Co-Commercialization Options. In the event of a Change of Control with respect to Pieris there shall be no

125

CONFIDENTIAL TREATMENT REQUESTED

impact on Pieris’ Co-Development and Co-Commercialization options as set forth in this Agreement; provided that, if such Change of Control is with an entity that, in the Calendar Year prior to such Change of Control, had revenues during its most recently concluded fiscal year from the sale of biopharmaceutical products that are within the top [***] ([***]) highest in the world (a “Top [***] Pharma Company”), then (i) AstraZeneca shall be permitted, by written notice to Pieris, to immediately terminate any unexercised CoDev Option and Co-Commercialization Options and, effective upon [***] ([***]) months prior written notice, to terminate Pieris’ rights under any Co-Commercialization Options that were exercised by Pieris prior to the closing of such Change of Control and (ii) if Pieris has exercised a CoDev Option, from and after the closing of such Change of Control, the resultant CoDev Products shall be treated as if they were Products for which Pieris does not have or has not exercised a CoDev Option with respect to the information sharing only (i.e., such Product shall not be subject to decision-making through the joint committee structure and AstraZeneca shall be entitled to disband the JSC and JDC). A Top [***] Pharma Company COC Acquiror Co-Developing a Product under this Agreement would specifically be entitled to the information reporting and sharing set forth in Sections 4.8 and 5.4.2 (except that AstraZeneca shall not be required to provide: (a) information that is specific to the Product and does not have any impact on Anticalin proteins per se; or (b) copies of such correspondence required by that Section 5.4.2 or to allow Pieris or Pieris’ successor to review and comment on any proposed response to such correspondence), but not as set forth in Sections 5.4.1, 5.5 and 6.4. For clarity, the payment and other obligations of AstraZeneca with respect to such Co-Developed Product would not be altered. For avoidance of doubt, if the COC Acquiror is not a Top [***] Pharma Company, then there shall be no change to the rights granted to Pieris under this Agreement.

15.7. Force Majeure. No Party will be held responsible to the other Party nor be deemed to be in default under, or in breach of any provision of, this Agreement for failure or delay in performing any obligation of this Agreement when such failure or delay is due to force majeure, and without the fault or negligence of the Party so failing or delaying. For purposes of this Agreement, force majeure means a cause beyond the reasonable control of a Party, which may include acts of God; acts, regulations, or laws of any government; war; terrorism; civil commotion; fire, flood, earthquake, tornado, tsunami, explosion or storm; pandemic; epidemic and failure of public utilities or common carriers. In such event the Party so failing or delaying will immediately notify the other Party of such inability and of the period for which such inability is expected to continue. The Party giving such notice will be excused from such of its obligations under this Agreement as it is thereby disabled from performing for so long as it is so disabled for up to a maximum of [***] ([***]) [***], after which time the Parties will negotiate in good faith any modifications of the terms of this Agreement that may be necessary to arrive at an equitable solution, unless the Party giving such notice has set out a reasonable timeframe and plan to resolve the effects of such force majeure and executes such plan within such timeframe. To the extent possible, each Party will use reasonable efforts to minimize the duration of any force majeure.

15.8. Notices. Any notice or request required or permitted to be given under or in connection with this Agreement will be deemed to have been sufficiently given if in writing and personally delivered or sent by internationally recognized overnight express courier service (signature required), prepaid, to the Party for which such notice is intended, at the address set forth for such Party below:

15.12. Severability.

Exhibit 1.110: Fully Burdened Manufacturing Cost


A.	General Principles


1.	The costs of Finished Product supplied by a Party for Development supply requirements or commercial supply requirements shall be at Fully Burdened Manufacturing Cost, calculated as described in Section B of this Exhibit, plus, if applicable, the Cost of Finishing, as described in Section C of this Exhibit below.


2.	Fully Burdened Manufacturing Cost accumulates costs as they are incurred and may or may not utilize a standard cost system; provided that to the extent a standard cost system for the Product is used for internal purposes at a Party, Fully Burdened Manufacturing Costs shall accumulate utilizing such standard cost system.

Fully Burdened Manufacturing Cost shall be calculated using methodology that is in accordance with a Party’s Accounting Standards at the election of such Party and consistently applied by such Party throughout its operations, without any mark-up. A Party may utilize a standard Fully Burdened Manufacturing Cost when reporting its commercial supply cost or Development supply cost, but will true-up such standard to its actual Fully Burdened Manufacturing Cost using a methodology that is in accordance with such Party’s Accounting Standards consistently applied by such Party.

If the Product is Manufactured in a Party’s facility that is also used to manufacture other products not included within the scope of this Agreement (a “Shared Facility”), only the value of the specific resources used for or reasonably allocated to the Manufacture of Product shall be included in the calculation of Fully Burdened Manufacturing Costs. The cost of idle or underutilized capacity (but not designated reserved capacity in a Product Development Plan or a Commercialization Plan) in a Shared Facility shall not be included in the calculation of Fully Burdened Manufacturing Cost.

Any reasonable capital expenditures incurred by a Party in the ordinary course of capacity planning in providing capacity for the Manufacture of Finished Product (including Formulated Bulk Product contained therein) shall be the responsibility of such Party. Depreciation related to other capital expenditures, calculated using methodology that is in accordance with Accounting Standards and consistently applied by a Party throughout its operations, shall be included in Fully Burdened Manufacturing Costs, as applicable. To the extent material modifications to a Party’s or its Affiliates’ facilities, or construction of new facilities by a Party or any of its Affiliates, are needed to provide capacity for the Manufacture of Finished Product, the Parties will agree to the allocation of any capital expenditures with respect thereto between the Parties.


B.	Fully Burdened Manufacturing Cost


1.	“Fully Burdened Manufacturing Cost” includes the following costs of preparations for, and the Manufacture of, Finished Product (including Formulated Bulk Product contained therein) (which for the purposes of this Section B shall include unformulated, formulated and failed lots).

139

CONFIDENTIAL TREATMENT REQUESTED

Confidential


i.	Direct Costs incurred by a Party:


1.	Direct labor, based on the actual hours consumed by manufacturing and facility personnel for Finished Product charged at an average hourly wage rate that is designed to approximate actual cost for each employee’s position.


2.	Direct labor fringe benefits, including, compensation expense (other than wages included in direct labor cost in paragraph B.1(i)1), payroll taxes and benefits allocated based on a proportionate percentage of direct labor costs charged to the Finished Product to total actual plant-wide labor costs, plus Product specific travel.


3.	Materials and supplies for making Finished Product (including Formulated Bulk Product contained therein), based on actual costs including any applicable freight, taxes, duties, customs or import fees, less any discounts or free goods.


4.	Other costs directly associated with or actually consumed for Finished Product (including Formulated Bulk Product contained therein), including, facility costs, depreciation, waste removal, miscellaneous supplies, outside testing, consulting fees, occupancy costs, maintenance, rent, insurance and site service support.


ii.	Indirect Costs incurred by a Party:

Plant support services, which includes functions such as quality control, process sciences, quality assurance, regulatory and validation. All general costs for each plant support service department, which includes, labor, payroll taxes, fringe benefits, materials and supplies, outside testing, consulting fees, depreciation, maintenance and occupancy costs, shall be allocated to the cost of the Product based on the proportion of actual labor hours consumed by each plant support service department on the Finished Product to total actual labor hours consumed by each plant support service department on all of a Party’s products or its Affiliates’ or collaborators’ products.

Overhead costs required to support the Manufacture of the Finished Product (including the Formulated Bulk Product contained therein). These overhead costs are allocated either based on actual labor hours or manufacturing process area square footage, but are only costs directly related to the plant in which the Product is Manufactured. Overhead costs allocated based on actual labor hours consumed include, general materials and supplies, consulting costs, and other labor costs such as general plant maintenance, management, engineering, janitorial services and administration, information services, travel and training, and vacation, holiday, personal and sick time. Overhead costs allocated based on Manufacturing process area square footage consist primarily of general facility costs that include, facility services and supplies, utilities, rent, real estate taxes, depreciation, general and preventative maintenance, insurance and waste removal.


iii.	The cost of a Third Party contract manufacturer as invoiced to a Party without any mark-up, including any fees paid to such Third Party to reserve capacity for the Product;

140

CONFIDENTIAL TREATMENT REQUESTED

Confidential

provided that the Parties will share any capital expenditures paid to a Third Party contract manufacturer as Development Costs.

Notwithstanding the foregoing, (i) Fully Burdened Manufacturing Cost shall include costs incurred with respect to, or as a result of, spoilage, obsolescence, expiration, or loss or failed or destroyed batches of Product except to the extent attributable to a Party’s or any of its Affiliates’ gross negligence or willful misconduct and (ii) any reimbursement from a Party to the other Party for capital expenditures in such other Party’s plant under this Agreement shall not be included in the basis of assets used to calculate depreciation included in Fully Burdened Manufacturing Costs.

Cost of Finishing. Cost of finishing is the cost of filling, device Manufacture and assembly, packaging, labeling and testing Finished Product, including freight, insurance and quality control. If such filling, device Manufacture and assembly, packaging, labeling or testing is performed by or on behalf of a Party, it shall be billed by the Party at its actual cost without any profit for the Party or mark-up by the Party. If such filling, device Manufacture and assembly, packaging, labeling, or testing is performed by a Third Party, the finishing, filling, device Manufacture and assembly, packaging and testing costs will be billed by the Party that contracts with the Third Party responsible for such activities at its Out-of-Pocket Costs without any mark-up and will include any fees paid to such Third Party to reserve capacity for the Product to the extent not included in the Fully Burdened Manufacturing Cost.

PRESS RELEASE

Pieris Pharmaceuticals and AstraZeneca Collaborate to Develop and Commercialize Anticalin-Based Inhaled Treatments for Respiratory Diseases


•	Pieris to receive $57.5 million USD in upfront and near-term milestone payments


•	Pieris has the potential to receive development-dependent milestones and eventual commercial payments for all products not exceeding $2.1 billion as well as tiered royalties


•	For programs co-developed by Pieris, the Company will be entitled to receive increased royalties or a gross margin share on worldwide sales, dependent on the level of investment to which Pieris commits


•	Pieris will host a conference call on Wednesday, May 3^rd at 10am EDT to discuss the collaboration

Boston, MA, May 3, 2017 – Pieris today announced a strategic collaboration in respiratory diseases with AstraZeneca to develop novel inhaled drugs that leverage Pieris’ Anticalin^® platform, including its lead preclinical drug candidate, PRS-060.

Anticalin molecules are engineered proteins which can mimic antibodies by binding to sites either on other proteins or on small molecules. They are smaller than monoclonal antibodies, offering the potential of direct delivery to the lung.

Under the collaboration, Pieris will be responsible for advancing its preclinical lead candidate, PRS-060, into Phase 1 clinical trials in 2017. PRS-060 is an Anticalin against interleukin-4 receptor alpha (IL-4Ra) with potential in asthma. AstraZeneca will fund all clinical development and subsequent commercialization programs and Pieris has the option of co-development and co-commercialization in the US from Phase 2a onwards. In addition, the parties will collaborate to progress four additional novel Anticalins against undisclosed targets for respiratory diseases with Pieris having the option to co-develop and co-commercialize in the US two of these programs.

Mene Pangalos, Executive Vice President, Innovative Medicines and Early Development Biotech Unit and Business Development, said: “At AstraZeneca, discovering and developing innovative new medicines to treat respiratory diseases is a key strategic priority. Our alliance with Pieris adds an important new modality to our respiratory portfolio and builds on our scientific expertise in inhaled formulation technologies. Pieris shares our passion for ground-breaking science and we look forward to working together to develop new, life-changing treatment options for patients.”

Stephen Yoder, President and Chief Executive Officer of Pieris, said: “Our partnership with AstraZeneca accelerates the transformation of Pieris into a fully-integrated drug development and commercial organization, comprising two main pillars in immunology: respiratory diseases and immuno-oncology, each of which is now anchored by a major alliance. We recognize AstraZeneca’s unparalleled expertise in the development of inhaled drugs, which will maximize the potential of PRS-060 and other inhaled Anticalin molecules to become valuable assets for both companies.”

AstraZeneca will make an upfront and near term milestone payments to Pieris in the amount of $57.5 million - $45 million USD of upfront payments and $12.5 million USD for the initiation of the PRS-060 Phase 1 trial. Pieris has the potential to receive development-dependent milestones and eventual commercial payments for all products not exceeding $2.1 billion as well as tiered royalties on the sales of any potential products commercialized by AstraZeneca. For programs co-developed by Pieris, the Company stands to receive increased royalties or a gross margin share on worldwide sales equal, dependent on the level of investment to which Pieris commits.

Louis Matis, M.D., Senior Vice President and Chief Development Officer of Pieris, said: “AstraZeneca, a leading innovator in respiratory diseases with considerable expertise in the development of inhaled products, is the ideal partner to exploit the potential of our platform in respiratory diseases. Based on the limitations of many types of biologic molecules, direct delivery to the lungs via inhalation has been challenging to date for other classes of therapeutic proteins. Anticalin proteins have unique properties, not least of which is their size and stability, and show considerable promise for this route of delivery.”

The collaboration agreement is conditional upon the expiration or early termination of the applicable waiting period (and any extension thereof) under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended.

PRS-060, an Anticalin protein potently engaging IL-4Rα, is being developed for patients suffering from moderate to severe asthma, many of whom are not able to control their asthma well with currently available medications. In a large proportion of asthma patients, the Th2 pathway plays an important role. IL-4 and IL-13 are the main cytokines involved in Th2-mediated asthma. Both signal via IL-4Rα, making IL-4Rα a cornerstone intervention point. PRS-060 differentiates from antibody approaches through inhaled delivery directly into the lungs, potentially resulting in efficacy and safety benefits. The local delivery may allow for lower doses than systemically administered antibodies, potentially also resulting in a significant cost of goods advantage over those therapies. Pieris has demonstrated proof of concept in animals as well as feasibility for pulmonary delivery with PRS-060.

Conference Call

Pieris will host an investor conference call on Wednesday, May 3, 2017 at 10:00 AM (EDT) to discuss the collaboration. To access the call, participants may dial 1-877-407-8920 (US & Canada) or 1-412-902-1010 (International) at least 10 minutes prior to the start of the call.

Except for disclosures permitted pursuant to Sections 6.1 or 6.3, or under any other agreement with AstraZeneca, either Party wishing to make a publication or public presentation relating to any jointly carried out activity that contains the Confidential Information of the other Party or any results of Research and Development activities under this Agreement (the “Publishing Party”) will deliver to the other Party (the “Reviewing Party”) a copy of the proposed written publication or presentation at least [***] ([***]) days prior to submission for publication or presentation. The Reviewing Party will have the right (a) to propose modifications to the publication or presentation for patent reasons or trade secret reasons or to remove Confidential Information of the Reviewing Party or its Affiliates, and the Publishing Party will remove all Confidential Information of the other Party if requested by the reviewing Party and otherwise reflect such Party’s reasonable comments into consideration, or (b) to request a reasonable delay in publication or presentation in order to protect patentable information. If the Reviewing Party requests a delay, the Publishing Party will delay submission or presentation for a period of [***] ([***]) days (or such shorter period as may be mutually agreed by the Parties) to enable the Reviewing Party to file patent applications protecting such Party’s rights in such information. With respect to any proposed publications or disclosures by investigators or academic or non-profit collaborators, such materials will be subject to review under this Section 6.2 to the extent that Licensee or Pieris, as the case may be, has the right and ability (after using commercially reasonable efforts to obtain such right and ability) to do so. Notwithstanding the foregoing, neither Party will submit or publish any article or other publication to or with any scientific journal or other publisher that requires, as a condition of publication, that the submitting Party agree to make available to the publisher or Third Parties any Licensed Product or other materials which are the subject of the publication. Except as set out above Licensee shall control in its discretion all publications and public presentations relating to the Research, Development, Manufacture and Commercialization of the Licensed Products and Pieris shall not make any such publication or public presentation without the prior written consent of Licensee.

10.6 Force Majeure. No Party will be held liable or responsible to the other Party nor be deemed to be in default under, or in breach of any provision of, this Agreement for failure or delay in fulfilling or performing any obligation of this Agreement when such failure or delay is due to force majeure, and without the fault or negligence of the Party so failing or delaying. For purposes of this Agreement, “force majeure” is defined as causes beyond the control of the Party, including, without limitation, acts of God; laws of any government; war; civil commotion; destruction of production facilities or materials by fire, flood, earthquake, explosion or storm; labor disturbances; epidemic; and failure of public utilities or common carriers. In the event of force majeure, Pieris or Licensee, as the case may be, will immediately notify the other Party of such inability and of the period for which such inability is expected to continue. The Party giving such notice will thereupon be excused from such of its obligations under this Agreement as it is thereby disabled from performing for so long as such Party is so disabled, up to a maximum of [***] ([***]) [***], after which time the Party not affected by the force majeure may terminate this Agreement. To the extent possible, each Party will use reasonable efforts to minimize the duration of any force majeure.

This First Amendment to the to the License and Collaboration Agreement entered into on January 4, 2017 (the “First Amendment”) is effective as of June 16, 2017 (the “First Amendment Effective Date”) by and between Les Laboratoires Servier, a corporation incorporated under the laws of France having offices and principal place of business at 50 Rue Carnot, 92284 Suresnes Cedex, France and Institut de Recherches Internationales Servier, a company duly organized and existing under the laws of France having offices and principal place of business at 50 Rue Carnot, 92284 Suresnes Cedex, France (individually and collectively, “Servier”), and Pieris Pharmaceuticals, Inc., a Nevada corporation having offices and principal place of business at 255 State Street, 9th floor, Boston, MA 02109 and Pieris Pharmaceuticals GmbH, a company organized and existing under the laws of Germany having offices and principal place of business at Lise-Meitner-str. 30, 85354 Freising, Germany (individually and collectively, “Pieris”). Servier and Pieris are individually referred to herein as a “Party” and collectively, as the “Parties”. The License and Collaboration Agreement entered into on January 4, 2017 between Pieris and Servier is referred to herein as the “Agreement” and, unless otherwise defined herein, capitalized words in this First Amendment shall have the meaning attributed to them in the Agreement.

RECITALS

WHEREAS, Pieris and Servier have entered into the Agreement, under which the Parties are Researching and Developing the Products;

WHEREAS, the Parties wish to amend certain provisions of the Agreement related to payment obligations of the Parties in connection with terminated Products or Dropped Products;

NOW, THEREFORE, in consideration of the promises and mutual covenants herein below, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Parties agree as follows:


1.	LICENSED BUILDING BLOCK PAYMENT OBLIGATIONS IN THE CASE OF DROPPED OR TERMINATED PRODUCTS

1.1 Section 4.1.3 of the Agreement contemplates that each Party is responsible for contributing certain Building Blocks to each Product (Pieris’ Contribution and Servier’s Contribution) and that such responsibility, including any milestones or royalties due in the case of a Building Block licensed from a Third Party (“Licensed Building Block”), continues even in the event that Pieris or Servier ceases its Development or Commercialization (including Manufacture thereof for purposes of such Development or Commercialization, as applicable) of a Product to the extent permitted under Section 5.2 of the Agreement (Dropped Products) or in the event that the Agreement is terminated with respect to a Product under Section 12.2 of the Agreement (terminated Products).

CONFIDENTIAL TREATMENT REQUESTED

[***]

Confidential

1.2 Notwithstanding Section 4.1.3 of the Agreement, the Parties agree that, for each Licensed Building Block, a Dropping Party or a Party that has terminated the development of a Product as permitted by the Agreement (a “Stopping Party”) shall not be required to pay any development milestones or sales milestones due to the Third Party licensor in connection with the continued Development or Commercialization of Products including such Licensed Building Block by the other Party (the “Continuing Party”) after the Drop Date or the date of termination of the Agreement with respect to the applicable Product, even if a Stopping Party would otherwise have had such obligation pursuant to Section 4.1.3 of the Agreement. Instead, payment of such development milestones or sales milestones due to such Third Party shall become the obligation of the Continuing Party. For purposes of the foregoing, if Pieris is the Stopping Party and Servier is the Continuing Party with respect to the Lead Product, the development milestones and sales milestones to be paid by Servier to Enumeral shall not exceed the lower of: (i) the amount of development milestones or sales milestones due by Pieris at that time and (ii) 37.75 Million USD and 45 Million USD, respectively, in the aggregate.

1.3 Notwithstanding Section 4.1.3 of the Agreement, the Parties agree that, for each Licensed Building Block, a Stopping Party shall be required to pay royalties due to the Third Party licensor in connection with the Licensed Building Blocks only up to the amount of any royalty payments received from the Continuing Party Commercializing the Dropped Product or the terminated Product, even if a Stopping Party would otherwise have had the obligation to pay the full amount of such royalties pursuant to Section 4.1.3 of the Agreement. The Continuing Party Commercializing the Dropped Product or the terminated Product shall be responsible to pay the remaining royalties (if any) due to the Third Party licensor.


2.	MISCELLANEOUS

2.1 This First Amendment supersedes all proposals, negotiations, conversations and/or discussions between or among Parties relating to the subject matter of this First Amendment and all past dealing or industry custom.

2.2 This First Amendment shall be integrated in and form part of the Agreement effective as of the First Amendment Effective Date. Except for the foregoing, the Agreement is hereby ratified and confirmed in accordance with its original terms.

2.3 This First Amendment may be signed in counterparts, each and every one of which will be deemed an original, notwithstanding variations in format or file designation which may result from the electronic transmission, storage and printing of copies of this First Amendment from separate computers or printers. Facsimile (including electronic) signatures will be treated as original signatures.
