1.3 Tax Consequences. For U.S. federal income Tax purposes, the Transaction is intended to constitute a transaction described in Section 351(a) of the Code, and the parties will report the Transaction as such for U.S. federal income Tax purposes. None of the parties will knowingly take any action, or fail to take any action, which action or failure to act would cause the Transaction to fail to qualify as a transaction described in Section 351(a) of the Code.

1.4 Waiver of Rights by Holders. At the Effective Time, each Holder hereby waives and relinquishes the following rights with regard to his respective shareholding in the Company as partial consideration for the receipt of Parent Common Stock:

Pieris/Marika Acquisition Agreement

(b) any and all options and/or rights to acquire shares in the Company resulting from convertible loan, convertible bonds, option rights or option bonds, in any case the totality of rights to acquire or subscribe for shares in the Company (the “Options”); and

(c) any and all rights such Holder may have under the CSA 2014, including, but not limited to, rights of first refusal.

1.5 Company Consent, Approval and Waiver. The Company hereby approves and accepts the contributions, assignments, delegations, transfers and waivers as set forth in Sections 1.1 and 1.4 above, including with respect to the Existing Shares, the Subscription Rights and all rights under the CSA 2014. Sec. 23 of the CSA 2012 referred to deferred payments to the Company’s capital reserves pursuant to Sec. 272 Para. 2 no. 4 German Commercial Code (Handelsgesetzbuch) resulting from the seed finance round in 2001, which are owed by the following Holders: Steffen Schlehuber, Claus Schalper, Dr. Karsten Schürle, MAPO Beteiligungsgesellschaft mbH and are subject to dilution and reduction. The Company and the Holders determined the value of such deferred payments to the Company’s capital reserves to remain EUR 0.00 in total under the IA 2014, and therefore did not make any reference hereto in the CSA 2014. As a matter of precaution the Company waives, with effect as of the Effective Time, all deferred payment claims against the aforementioned Holders, who accept such waiver.

1.6 Parent’s Acceptance of the Existing Shares. Parent hereby accepts the contribution, transfer, assignment and delivery of the Existing Shares under Section 1.1(a). The Company hereby accepts the waiver of rights under the CSA 2014 as set forth under Section 1.4 above. The right to receive undistributed profits with regard to Existing Shares as well as any Subscription Rights shall belong exclusively to Parent.

1.7 Further Action. If, at any time after the Effective Time, any further action is determined by Parent and the Company to be necessary or desirable to carry out the purposes of this Agreement or to vest the Company with full right, title and possession of and to all rights and property of the Company, the officers and directors of the Company and Parent shall be, to the extent permitted by law, fully authorized (in the name of the Company and otherwise) to take such action. If, at any time after the Effective Time, any further action is determined by Parent and the Company to be necessary or desirable to carry out the purposes of this Agreement or to vest Parent with full right, title and possession of the Existing Shares, the officers and directors of the Company and Parent shall be, to the extent permitted by law, fully authorized (in the name of Parent and otherwise) to take such action. Following the Effective Time, the Holders agree to take all reasonable action requested by Parent or the Company in order to approve any of the actions described herein on behalf of the Company or to vest Parent with full right, title and possession of the Existing Shares.

1.8 Registration Rights. The Holders acknowledge that the Company intends for Parent to enter into a private offering of its equity securities immediately following the Effective Time in one or more closings (the “Private Offering”) pursuant to which the investors in such Private Offering will enter into a registration rights agreement with Parent in the form attached hereto as Appendix I (the “Registration Rights Agreement”). Not later than the consummation of the Private Offering, Parent and the Holders shall enter into the Registration Rights Agreement, pursuant to which Parent shall provide certain registration rights to the

Pieris/Marika Acquisition Agreement

Holders (in addition to the investors in the Private Offering) with respect to the shares of Parent Common Stock received by them pursuant to this Agreement. In the event that, for any reason, the Private Offering is not consummated within thirty (30) days following the Effective Time, Parent and the Holders shall execute and deliver the Registration Rights Agreement as modified to remove any reference to such Private Offering.

The Split-Off Subsidiary does not intend to incur debts beyond its ability to pay such debts as they mature (taking into account the timing and amounts of cash to be payable on or in respect of its debt).

SECTION 5 LEGAL CONSEQUENCES.

5.1 The parties of this Agreement agree that the rights and remedies which the parties may have with respect to the breach of a representation, warranty, covenant or agreement or with respect to an indemnity contained in this Agreement are limited to the rights and remedies explicitly contained herein.

5.2 If one or more of the representations and warranties made by one of the Holders in this Agreement proves to be completely or partially inaccurate or incomplete then Parent shall be entitled to demand that the respective Holder puts Parent or the Company into the same situation it would have been had such representation or warranty been accurate and complete or had such obligation been complied with (Naturalrestitution) within a period of two months following receipt of a written demand. If the respective Holder fails to establish the said situation within such time period following such demand, or if the establishment of such situation is not possible, or is unacceptable to Parent or the respective Holder, Parent shall be entitled to demand payment of its (or the Company’s) damages based on or arising out of such inaccuracy or failure (kleiner Schadensersatz) (collectively, the “Damages”).

5.3 Parent shall, to the extent it has been positively aware of the situation, advise the Holders without undue delay (unverzüglich) in writing concerning the inaccuracy of a representation or warranty or the failure of Holders to comply with their obligations, the underlying facts and the expected amount of the Damages (hereinafter referred to as “Parent’s Claim”). Parent shall provide the Holders with the information forming the basis of the respective Parent’s Claim.

Pieris/Marika Acquisition Agreement

18

5.4 The parties agree that the provisions contained in this Agreement conclusively settle the Holders’ liability to Parent following the Closing and the legal consequences of any breach of this Agreement, in particular regarding the inaccuracy of the representations or warranties made by and the failure by the Holders to perform their obligations under this Agreement and that in the event of a breach of such representations or warranties and obligations or other legal, contractual or quasi-contractual obligations of the Holders, Parent shall not be entitled to any other claims under or in connection with this Agreement following the Closing. Insofar as legally permissible, i.e. not in cases of willful misconduct (Vorsatz) or fraudulent intent (Arglist) on the part of Holders, Parent hereby waives the right following the Closing to raise any other contractual, quasi-contractual legal or other rights or claims – irrespective of the legal grounds thereof – and, in particular the right to rescind, claims to large damage compensation (großer Schadenersatz) and to assert claims to reverse transactions, rights of avoidance, claims for supplementary performance as well as claims for the positive violation of a contractual duty and frustration of contract. The Holders hereby accept such waiver.

5.5 The parties further agree that the representations and warranties do not under any circumstances constitute a “representation and warranty concerning the quality of the object” within the meaning of Section 443 of the German Civil Code (BGB). The parties consequently expressly waive the application of Sections 442 and 444 of the German Civil Code (BGB) following the Closing; Parent further expressly waives any rights pursuant to Sections 437 through 441 of the German Civil Code (BGB) following the Closing. Section 377 of the German Commercial Code (HGB) shall not apply following the Closing. Should it turn out that the aforementioned provisions concerning the limitation of the Holders’ liability are completely or partially ineffective, Parent waives any right to bring claims following the Closing against the Holders, going beyond the limitations on liability in this Section 5 and the other limitations on liability contained in this Agreement, which the parties hereto intended to stipulate in the aforementioned provisions. The Holders hereby accept such waivers.

5.6 Following the Closing, Parent shall only be entitled to bring claims against a Holder hereunder if and to the extent that an individual claim exceeds the amount of EUR 25,000.00 (in words: twenty-five thousand euros) and, in addition, all claims in total exceed the amount of EUR 1,000,000.00 (in words: one million euros); thereafter, the claims are payable in full (exemption amount; Freigrenze). The total amount of claims by Parent against a Holder hereunder following the Closing shall not exceed fifty percent of the pre money valuation of the respective shares of the Company with regard to each contributing Holder hereunder.

5.7 The limitations of liability pursuant to Section 5.6 shall not apply to willful or fraudulent acts of the Holders. In this case, the claims of Parent under this Agreement following the Closing shall be limited to the consideration received by the Holders hereunder.

5.8 The Holders’ liability pursuant to this Agreement following the Closing shall be excluded if and to the extent that one of the following situations exists:

(a) The fact or Damages themselves forming the basis of the inaccuracy and/or incompleteness of the representations and warranties has been disclosed to Parent in this Agreement and/or its schedules and exhibits.

Pieris/Marika Acquisition Agreement

19

(b) The Damages have been completely or partially taken into account in one, several or all of the Company’s financial statements as a result of liability reserves or accruals.

(c) The Damages are offset in full or in part within Parent and/or the Company pursuant to the principles of benefit-sharing (Grundsätze des Vorteilsausgleichs).

(d) The Damages stem from the fact that as far as is currently known an existing law or other existing legal provision is being amended, or a new law or another new legal provision is coming into force, or from the fact that an official order is being issued.

(e) The Parent’s Claim has been satisfied through any insurance.

(f) Contributory negligence pursuant to the legal principle contained in Section 254 of the German Civil Code (BGB) regarding the creation of the Parent’s Claim has to be attributed to Parent.

5.9 Should one or more of the representations or warranties made by Parent under this Agreement turn out to be incorrect and/or incomplete, the provisions of this Section 5 shall apply mutatis mutandis.

5.10 Any claim by Parent with respect to the title or ownership of, and/or lack of encumbrances on, the Existing Shares represented by the Holders under Section 3.1 (a) shall survive indefinitely. All other representation and warranty claims shall expire, in deviation from the statutory provisions, two (2) years after the Closing Date, if and to the extent any provision in this Agreement does not provide otherwise.
