Opportunity to Investigate. Prior to the execution of this Agreement, AZ and its advisors have had the opportunity to ask questions of, and receive answers from, representatives of the Company concerning the terms and conditions of the transactions contemplated hereby, and the finances, operations, business and prospects of the Company. AZ and its advisors have also had the opportunity to obtain additional information that AZ believed to be necessary to verify the accuracy of information furnished about the Company. Accordingly, AZ has independently evaluated the risks of purchasing the Shares, and AZ is satisfied that it has received information with respect to all matters that it considers material to its decision to make this investment and has based the decision to acquire the Shares solely on such information. Acquisition for Investment. AZ (i) is acquiring the Shares for its own account for the purpose of investment and not with a view to or for sale in connection with any distribution thereof, and AZ has no present intention to effect, or any present or contemplated plan, agreement, undertaking, arrangement, obligation, indebtedness, or commitment providing for, any distribution of Shares, (ii) is an “accredited investor” as defined in Rule 501(a) under the Securities Act, (iii) has carefully reviewed the representations of the Company contained in this Agreement and has made inquiry concerning the Company, its business and its personnel, and (iv) has sufficient knowledge and experience in finance and business that it is capable of evaluating the risks and merits of its investment in the Company and is able financially to bear the risks thereof. However, by making the representations herein, AZ does not agree to hold any of the Shares for any minimum period of time and reserves the right, subject to the provisions of this Agreement, at all time to sell or otherwise dispose of all or any part of the Shares pursuant to an effective registration statement under the Securities Act or under an exemption from such


 
Execution Version registration and in compliance with applicable federal and state securities laws.. Exempt Offering. AZ acknowledges that the Shares have not been registered under the Securities Act and are being offered and sold pursuant to an exemption from registration contained in the Securities Act based in part upon the representations of AZ contained in this Agreement. 3. RESTRICTIONS ON TRANSFER Restrictions on Transfer. The Shares shall not be sold or transferred unless the transfer (i) complies with Rule 144, or an exemption from registration under the Securities Act, (ii) is pursuant to a registration statement under the Securities Act covering the resale of such Shares or (iii) is to the Company. Legend. Each certificate or book-entry statement representing the Shares shall bear a legend substantially in the following form: “THE SHARES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR ANY STATE SECURITIES LAW AND THEY MAY NOT BE OFFERED, SOLD, TRANSFERRED, HYPOTHECATED OR OTHERWISE ASSIGNED BY ANY PERSON, INCLUDING A PLEDGEE, UNLESS (1) EITHER (a) SUCH SHARES FIRST SHALL HAVE BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR (b) THE TRANSFER COMPLIES WITH RULE 144 OR AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND, IF REQUESTED BY THE COMPANY, THE COMPANY SHALL HAVE RECEIVED AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE COMPANY THAT AN EXEMPTION FROM REGISTRATION UNDER SUCH ACT IS THEN AVAILABLE, AND (2) THERE SHALL HAVE BEEN COMPLIANCE WITH ALL APPLICABLE STATE SECURITIES LAWS.”


 
Execution Version Legend Removal. The Shares shall not be required to bear the legend set forth in Section 3.2 (i) after the registration of such Shares for resale under the Securities Act, (ii) following any sale of such Shares pursuant to Rule 144 or (iii) if such Shares are eligible for sale under Rule 144 without the need to satisfy the current public information requirement under Rule 144 and without volume or manner-of-sale restrictions. Pieris agrees that following such time as the legend is no longer required under this Section 3.3, no later than two (2) Business Days following the delivery by AZ of (i) an instrument, whether certificated or uncertificated, representing the Shares issued with a restrictive legend, (ii) a written request addressed to Pieris that such restrictive legend be removed, and (iii) customary broker and representation letters in form and substance reasonably satisfactory to Pieris, Pieris will deliver or cause to be delivered to AZ an instrument, certificated or uncertificated as directed by AZ, representing such Shares that is free from such restrictive legend. In connection therewith, Pieris shall cause its counsel to issue a legal opinion to Pieris’s transfer agent promptly if required by Pieris’s transfer agent to affect the removal of the legend from the Shares. Each party will be responsible for its fees incurred in connection with such request and removal. For the avoidance of doubt, Pieris will be responsible for fees incurred in connection with any opinion delivered by its counsel pursuant to this Section 3.3. Rule 144 Reporting. With a view to making available to AZ the benefits of certain rules and regulations of the Commission which may permit the sale of the Shares to the public without registration, the Company agrees to use its commercially reasonable efforts to make and keep current public information with respect to the Company available, as those terms are understood and defined in Rule 144, at all times during the period commencing on the Execution Date and ending on the one-year anniversary of the Closing. 4. COVENANTS OF THE COMPANY. Listing of Securities. In the time and manner required by Nasdaq, the Company shall prepare and file with Nasdaq a Listing of Additional Shares form covering all of the Shares and shall use its commercially reasonable efforts to take all steps necessary to obtain confirmation from Nasdaq that it has completed its review of such form with no objection to the transactions contemplated hereby. Furnishing of Information. Until the date that AZ no longer holds any Registrable Securities, the Company shall use its commercially reasonable efforts to timely file (or obtain extensions in respect thereof and file within the applicable grace period) all reports required to be filed by the Company after the date hereof pursuant to the Exchange Act. During such period, if the Company is not required to file reports pursuant to the Exchange Act, it will prepare and furnish to AZ and make publicly available in accordance with Rule 144(c) such information as is required for AZ to sell the Registrable Securities under Rule 144. 5. REGISTRATION RIGHTS. Registration. Pieris shall prepare and, as soon as practicable but in no event later than sixty (60) calendar days following the Closing (the “Filing Deadline”), file with the Commission a Registration Statement on Form S-3


 
Execution Version covering the resale of the Registrable Securities (the “Registration Statement”). In the event that Form S-3 is not available for the registration of the resale of Registrable Securities hereunder, Pieris shall (i) register the resale of the Registrable Securities on another appropriate form reasonably acceptable to AZ and (ii) undertake to register the Registrable Securities on Form S-3 promptly after such form is available; provided that Pieris shall use its commercially reasonable efforts to maintain the continuous effectiveness of the Registration Statement then in effect until such time as a Registration Statement on Form S-3 covering the Registrable Securities has been declared effective by the Commission. Pieris shall use its commercially reasonable efforts to have the Registration Statement declared effective by the Commission as soon as practicable, but in no event later than the thirtieth (30th) calendar day following the Filing Deadline (or, in the event the Commission reviews and has comments to the Registration Statement, the sixtieth (60th) calendar day following the Filing Deadline) (the “Registration Statement Effective Date”). By 5:30 p.m. (Eastern time) on the second (2nd) Business Day following the Registration Statement Effective Date, the Company shall file with the Commission, in accordance with Rule 424 under the Securities Act, the final prospectus to be used in connection with sales pursuant to such Registration Statement. Notwithstanding the foregoing, Pieris may delay the filing or effectiveness of the registration of Registrable Securities pursuant to this Section 5.1 or suspend the use of the Registration Statement (and AZ hereby agrees not to offer or sell any Registrable Securities pursuant to such Registration Statement) for a period of not more than ninety (90) calendar days if (i) Pieris reasonably believes that there is or may be in existence material nonpublic information or events involving Pieris, the failure of which to be disclosed in the prospectus included in the Registration Statement could result in a Violation, or (ii) the consummation of any business combination by Pieris has occurred or is probable and which business combination would require the filing of financial statements pursuant to Rule 3-05 or Article 11 of Regulation S-X promulgated by the Commission or any similar successor rule. If Pieris exercises its right to delay the filing or effectiveness or suspend the use of the Registration Statement hereunder, the applicable time period during which the Registration Statement is to remain effective will be extended by a period of time equal to the duration of the suspension period. If so directed by Pieris, AZ will (i) not offer to sell any Registrable Securities pursuant to the Registration Statement during the period in which the delay or suspension is in effect after receiving notice of such delay or suspension; and (ii) use its commercially reasonable efforts to deliver to Pieris (at Pieris’s expense) all copies, other than permanent file copies then in AZ’s possession, of the prospectus relating to such Registrable Securities current at the time of receipt of such notice. Pieris will use its commercially reasonable efforts to maintain the continuous effectiveness of the Registration Statement (or another shelf registration statement that includes the Registrable Securities) until the date on which all of the Registrable Securities included in such registration statement have actually been sold. Pieris shall (i) prepare and file with the Commission such


 
Execution Version amendments (including post-effective amendments) and supplements to the Registration Statement and the Rule 424 prospectus used in connection with such Registration Statement as may be necessary to keep such Registration Statement effective as to the Registrable Securities during the Registration Period, and (ii) during such period, comply with the provisions of the Securities Act with respect to the disposition of all Registrable Securities covered by such Registration Statement until such time as all of such Registrable Securities shall have been disposed of in accordance with the intended methods of disposition by AZ as set forth in such Registration Statement. Pieris shall ensure that the Registration Statement (including any amendments or supplements thereto and prospectuses contained therein) shall not contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in the light of the circumstances in which they were made, not misleading. In no event shall AZ be identified as a statutory underwriter in the Registration Statement unless requested by the Commission; provided that if the Commission requests that AZ be identified as a statutory underwriter in the Registration Statement, AZ will have an opportunity to withdraw the Registrable Securities from the Registration Statement. Registration Expenses. Pieris will pay all Registration Expenses incurred in connection with the registration of Registrable Securities pursuant to this Section 5. All Selling Expenses relating to the distribution of the Registrable Securities applicable to Registrable Securities sold by AZ incurred in connection with the registration pursuant to this Section 5 will be borne by AZ. Notification of Certain Events. At its expense Pieris shall advise AZ within two (2) calendar days: (i) when the Registration Statement or any post-effective amendment thereto has become effective; (ii) of any request by the Commission for amendments or supplements to the Registration Statement or the prospectus included therein or for additional information; (iii) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or the initiation of any proceedings for such purpose; (iv) of the receipt by Pieris of any notification with respect to the suspension of the qualification of the Shares included therein for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; and (v) subject to the provisions in this Agreement, of the occurrence of any event that requires the making of any changes in the Registration Statement or prospectus included therein so that, as of such date, the statements therein are not misleading and do not omit to state a material fact required to be stated therein or necessary to make the statements therein (in the case of the prospectus, in the light of the circumstances under which they were made) not misleading. Upon receipt of any notice from Pieris of the happening of any of the foregoing, AZ will immediately discontinue offers and sales of the Registrable Securities under the Registration Statement (excluding, for the avoidance of doubt, sales conducted pursuant to Rule 144) until AZ receives copies of a supplemental or amended prospectus (which Pieris agrees to promptly prepare) that corrects the misstatement(s) or omission(s) referred to above and receives notice that any post-effective amendment has become effective or unless otherwise notified by Pieris that it may resume such offers and sales. Pieris shall use its commercially reasonable efforts to obtain the withdrawal of any order suspending the effectiveness of the Registration Statement as soon as reasonably


 
Execution Version practicable. Upon the occurrence of any event contemplated in clauses (i) through (v) above, except for such times as Pieris is permitted hereunder to suspend, and has suspended, the use of the prospectus forming part of the Registration Statement, Pieris shall use its commercially reasonable efforts to as soon as reasonably practicable prepare a post-effective amendment to such Registration Statement or a supplement to the related prospectus, or file any other required document so that, as thereafter delivered to AZ, such prospectus will not include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading. Certain Conditions. It will be a condition of AZ’s rights hereunder to have Registrable Securities owned by it registered that: (i) AZ will cooperate with Pieris by supplying information and executing documents relating to Pieris or the securities of Pieris owned by AZ that are reasonably necessary to effectuate the registration of the Registrable Securities; and (ii) AZ will enter into such undertakings and take such other actions relating to the conduct of the proposed offering that Pieris may reasonably request as being necessary to ensure compliance with federal and state securities laws and the securities laws of any applicable jurisdiction and the rules or other requirements of the applicable exchange. In the event of any registration under the Securities Act of any Registrable Securities pursuant to this Section 5, Pieris will indemnify and hold harmless AZ, each of its directors, officers, employees, Affiliates and equity holders against such losses, claims, damages or liabilities (including reimbursement for reasonable and documented legal and other expenses) to which AZ or any such director, officer, employee, Affiliate or equity holder may become subject under the Securities Act, the Exchange Act or other federal or state law, insofar as such losses, claims, damages or liabilities arise out of or are based upon a Violation; provided, however, that the indemnity agreement contained in this Section 5.4 will not apply to amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected without Pieris’s consent, which consent will not be unreasonably withheld, conditioned or delayed, nor will Pieris be liable in any such case for any such loss, claim, damage, liability or action to the extent that it arises out of or is based upon a Violation that occurs in reliance upon and in conformity with written information furnished to Pieris expressly for use in connection with such registration by any of such indemnified parties; and provided, further that AZ will indemnify and hold harmless Pieris, each of its directors, its officers, and each person, if any, who controls Pieris within the meaning of the Securities Act, against such losses, claims, damages or liabilities (including reimbursement for reasonable and documented legal and other expenses) to which Pieris or any such director, officer or controlling person may become subject under the Securities Act, the Exchange Act or other federal or state law, insofar as such losses, claims, damages or liabilities arise out of or are based upon a Violation, in each case, to the extent (and only to the extent) that such Violation occurs in reliance upon and in conformity with written information furnished to Pieris expressly for use in connection with such registration by any of such indemnifying parties, provided, however, that the indemnity agreement contained in this Section 5.4 will not apply to amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected without AZ’s consent, which consent will not be unreasonably withheld, conditioned or delayed; provided, further, that in no event shall the obligations of AZ in this Section 5.4 exceed the net proceeds received by it from the sale of its Registrable Securities related to the matter in which losses or damages are sought.

[Signature Page to Pieris and AZ Subscription Agreement] IN WITNESS WHEREOF, the undersigned have caused this Agreement to be executed as of the day and year first above written. PIERIS PHARMACEUTICALS, INC. ASTRAZENECA AB By: __________________________ By: __________________________ Name: Stephen Yoder Name: Ulrika Lilja Title: President and CEO Title: Authorised Signatory


 
Exhibit A-1 Legal Opinion


 
Re: Pieris Pharmaceuticals, Inc. Ladies and Gentlemen: This letter is being furnished to you pursuant to Section 1.3.1 of the Subscription Agreement, dated March 29, 2021 (the “Subscription Agreement”), by and between Pieris Pharmaceuticals, Inc., a Nevada corporation (the “Company”), and AstraZeneca AB (“AZ”). Capitalized terms used herein and not defined herein shall have the respective meanings ascribed thereto in the Subscription Agreement. We have acted as counsel to the Company in connection with the Subscription Agreement and the transactions contemplated thereby, including the issuance of the Shares. In connection with the rendering of the opinions set forth below, we have reviewed copies of executed originals or counterparts of the following documents: • the Subscription Agreement; • the resolutions of the Board of Directors of the Company approving and authorizing the Subscription Agreement and the transactions contemplated thereby; • the Company’s Amended and Restated Articles of Incorporation, as amended; and • the Company’s Amended and Restated Bylaws. Insofar as the opinions in this letter relate to factual matters, information with respect to which is in the possession of the Company, we have relied, in the absence of our actual knowledge to the contrary, upon certificates, statements and representations of officers and other representatives of the Company, representations made in or pursuant to the Subscription Agreement, as well as certificates contemporaneously delivered by the Company to us. In our examination of the documents referred to above, we have assumed, with your permission and without independently verifying such assumptions: (i) the genuineness of all signatures on all documents and instruments examined by us; (ii) the authenticity of all documents submitted to us as originals; and (iii) the conformity to the originals of all documents submitted to us as certified, photostatic or conformed copies, including documents transmitted electronically, and the authenticity of the originals of such documents. We have further assumed, also with your permission and without independent inquiry or investigation, that AZ has all requisite power and authority, has taken all necessary action (corporate or otherwise), and has received all necessary consents and approvals, to authorize, execute and deliver the Subscription Agreement, and to effect the transactions contemplated thereby, that the Subscription Agreement has been duly authorized and validly executed and delivered by AZ, that, with respect to AZ, the Subscription Agreement constitutes legal, valid and binding obligations, and that the representations and warranties made by AZ in the Subscription Agreement and pursuant thereto are true and correct. Any reference to “our knowledge,” “matters known to us,” or words of similar import shall, except as otherwise specifically described herein, mean the conscious awareness of the existence or absence of any facts or other information by any lawyer in this firm who has participated directly in our representation of the Company in connection with the transactions contemplated by the Subscription Agreement. Other than as set forth herein, we have not undertaken, for purposes of this opinion letter, any independent investigation to determine the existence or absence of such


 
facts, and no inference as to our knowledge of the existence or absence of such facts should be drawn from the fact of our representation of the Company. Moreover, we have not searched any computerized or electronic databases or the dockets of any court, regulatory body, or governmental agency or other filing offices in any jurisdiction. Our opinions below are limited to the federal law of the United States of America, the laws of the Commonwealth of Massachusetts and the General Corporation Law of the State of Delaware and we express no opinion with respect to the laws of any other jurisdiction. The opinions expressed herein are based upon currently existing statutes, rules, regulations and judicial decisions and, except as otherwise noted, are rendered as of the date hereof. We disclaim any obligation to advise you of any change in the foregoing sources of law, subsequent developments in the law, or changes in facts or circumstances which might affect any matters or opinions set forth herein. We are opining only as to the matters expressly set forth herein, and no opinion should be inferred as to other matters. We express no opinion with respect to any questions of choice of law, choice of venue or conflicts of laws. Our opinions expressed in paragraph 1 below as to the good standing and foreign qualification of the Company are based solely upon good standing or similar certificates issued by the appropriate authorities in the Commonwealth of Massachusetts, and our opinions with respect to such matters are rendered as of the date of such good standing or similar certificates and limited accordingly. For purposes of our opinion set forth in paragraph 2 below, we express no opinion as to the enforceability of any provision of the Subscription Agreement that: (a) requires the Company to make payment upon breach or otherwise provides for liquidated damages, monetary penalties or other economic remedies to the extent such provisions are deemed to constitute a penalty, (b) provides rights of indemnity or contribution with respect to a liability where such indemnification or contribution is contrary to public policy and invalid under law or court decisions, or (c) relates to whether the laws of any particular jurisdiction apply or the submission to jurisdiction or waiver of jury trial provisions. For purposes of our opinion set forth in paragraph 5, we have assumed that (a) neither the Company nor any person acting on behalf of the Company has offered or sold the Shares or other securities of the Company that could be “integrated” with the sale of the Shares by any form of general solicitation or general advertising within the meaning of Regulation D promulgated under the Securities Act and (b) there will be no offerings or sales of securities of the Company after the date hereof in a transaction that can be so “integrated.” Based upon the foregoing assumptions, limitations and qualifications, we are of the opinion that: 1. The Company is qualified to do business as a foreign corporation and is in good standing in the Commonwealth of Massachusetts. 2. The Subscription Agreement has been duly authorized, executed and delivered by the Company and constitutes a valid and binding agreement of the Company enforceable against the Company in accordance with its terms. 3.
