I agree that, during my employment by the Company or any Affiliate (each as defined in the Plan) and for a period of twelve (12) consecutive months after my employment ceases for any reason, I shall not, directly or indirectly, (i) either alone or in association with others, (A) induce, counsel, advise, solicit or encourage, or attempt to induce, counsel, advise, solicit or encourage any employee to leave the employ of the Company, or any of its Affiliates, or accept employment with any other person or entity, (B) induce counsel, advise, solicit or encourage, or attempt to induce, counsel, advise, solicit or encourage any person who at the time of such inducement, counseling, advice, solicitation or encouragement had left the employ of the Company, or any of its Affiliates, within the previous six (6) months to accept employment with any person or entity besides the Company, or any of its Affiliates, or hire or engage such person as an independent contractor, or (C) solicit, interfere with, or endeavor to cause any customer, client, or business partner of the Company, or any of its Affiliates, to cease or reduce its relationship with the Company, or any of its Affiliates, or induce or attempt to induce any such customer, client, or business partner to breach any agreement that such customer, client, or business partner may have with the Company, or any of its Affiliates; and (ii) whether or not for compensation, and whether or not as an employee, be engaged in or have a financial interest in any business, competing with the business of the Company or of any Affiliate within any state, region or locality in which the Company or such Affiliate is doing business or marketing products at the time of the cessation of my employment, as the business of the Company or such Affiliates may then be constituted. With respect to this sub-section, however, it is understood and agreed that a business is not competing with the business of the Company or any Affiliate if (A) my duties with respect to such business relate solely to discrete business units that do not compete with the business of the Company or any Affiliate; or (B) the competitive activity is limited to geographical markets or products in which the Company or Affiliate was not engaged (whether by manufacture, distribution, sale, or development for manufacture, distribution, or sale) during the two (2) years immediately preceding my ceasing to be employed by the Company. Ownership of no more than .5% of the outstanding voting stock of a publicly traded corporation shall not constitute a violation of this provision. (2) Miscellaneous. (i) If any restriction in this Exhibit is found by a court of competent jurisdiction to be unenforceable because it extends for too long a period or covers too great a range of activities or in too broad a geographic area, it shall be interpreted to be effective to the extent it is enforceable. The invalidity or unenforceability of any provision shall not affect the validity or enforceability of any other provision of this Exhibit. (ii) I acknowledge the restrictions contained in this Exhibit are reasonable and necessary for the protection of the business and goodwill of the Company. I agree that any breach or threatened breach of this Exhibit will cause the Company substantial and irrevocable damage that is difficult to measure and that a remedy at law is not adequate. In the event of breach or threatened breach, I agree that the Company, in addition to other available remedies, shall have the right to seek specific performance and injunctive relief without posting a bond. (iii) This Exhibit supersedes all prior agreements, written or oral, between the Company and me relating to the subject matter of Section 1, including any provisions in the Plan; provided however, that this Exhibit is not intended, and shall not, supersede the provisions of any agreement between the Company and me relating to non-disclosure of proprietary information and assignment of inventions to the Company. In the event that I am a party to a non-disclosure and invention assignment agreement (an “Inventions Agreement”)

Nonsolicitation/Noncompete Acknowledgement Page 2 with the Company on the date I execute this Exhibit, the provisions of this Exhibit shall supersede only the specific portions of the Inventions Agreement that relate to non-competition and non-solicitation. The remaining provisions of the Inventions Agreement, including but not limited to any provisions relating to non- disclosure and assignment of inventions, shall remain in full force and effect. In the event that I execute this Exhibit and thereafter execute the Company’s form of non-disclosure and inventions assignment agreement (the “Company’s Form Agreement”), the Company and I hereby agree that, notwithstanding the order in which the agreements were executed, the non-competition and non-solicitation provisions of this Exhibit shall be deemed to supersede the non-competition and non-solicitation terms of the Company’s Form Agreement, but that all other terms of the Company’s Form Agreement to which I am a party shall remain in full force and effect. (iv) This Exhibit shall apply irrespective of the reason my employment ends. No delay or omission by the Company in exercising any right under this Exhibit will operate as a waiver of that or any other right. A waiver or consent given by the Company on any one occasion is effective only in that instance and will not be construed as a bar to or waiver of any right on any other occasion. (v) This Exhibit shall be binding upon and inure to the benefit of both parties and their respective successors and assigns, including any corporation or entity with which or into which the Company may be merged or that may succeed to all or substantially all of its assets or business. (vi) This Exhibit may not be modified, changed or discharged in whole or in part, except by an agreement in writing signed by the Company and me. This Exhibit shall be governed by and construed as a sealed instrument under and in accordance with the laws of the State of Delaware without regard to conflicts of law provisions.

EXHIBIT III Second Amended and Restated Senior Management Severance Plan Acknowledgement Form I acknowledge and agree that: 1. I am electing to continue to be a participant with the enhanced benefits in, and to be subject to the terms and conditions of, the Plan; 2. I will comply with the terms and conditions of Exhibit II hereto, including the non-compete and non- solicitation provisions; 3. I agree that any indemnification agreement, stock option agreement, shareholder agreement, confidentiality obligations, and inventions assignment agreements that I may have with the Company or its affiliates are not affected by this letter or by my participation in the Plan and remain in full force and effect; 4. I am and will remain an at-will employee, and my employer or I may terminate my employment at any time for any reason or for no reason; and 5. My compensation is governed by my employer’s general benefit plans, as they may be amended from time to time, unless the Company notifies me otherwise in writing. ______________________________________________ Joseph Papa Chief Executive Officer

Appendix C - Page 1 APPENDIX C EMPLOYEE NON-DISCLOSURE, NON-SOLICITATION AND ASSIGNMENT AGREEMENT

U.S. Version - November 2018 1 EMPLOYEE NON-DISCLOSURE, NON-SOLICITATION, AND ASSIGNMENT AGREEMENT This Employee Non-Disclosure, Non-Solicitation, and Assignment Agreement (“Agreement”) is made this day of , 20 by and between Emergent BioSolutions Inc. and any “Affiliate Entity” (defined below) and their successors and assigns (collectively, “Emergent”) and (hereinafter, the “Employee”) (singularly and collectively, the “Party” or “Parties”). 1. Consideration. Emergent desires to employ or continue the employment of Employee, and Employee desires to accept or continue employment with Emergent. In consideration of such employment and the provision of Proprietary Information described in Section 2 below, Employee agrees to the provisions of this Agreement. 2. Proprietary Information. Emergent may disclose, or may have disclosed, to Employee “Proprietary Information” (defined below) relating to the business of Emergent. Employee recognizes that Emergent is engaged in the business of research, development, manufacture, and commercialization of vaccines; therapeutics; contract manufacturing; contract research/development; and allied activities, and such businesses require the fullest security of “Proprietary Information” (defined below) for their successful operation. Employee shall use Employee’s best efforts and diligence, both during and after employment with Emergent and regardless of how, when, and why employment ends, to protect the confidential and proprietary nature of all Proprietary Information. Employee shall not use, directly or indirectly, in any form or by any means, any Proprietary Information, except as may be necessary for the good faith performance of Employee’s duties for Emergent, and shall not disclose any Proprietary Information to anyone other than employees of Emergent who need to know such information for purposes of their employment or as otherwise authorized by Emergent. Employee shall promptly deliver to Emergent at the termination of employment or at any other time at Emergent’s request, without retaining any copies in paper, electronic, or other form, all documents and other materials in Employee’s possession relating, directly or indirectly, to Proprietary Information. Employee agrees and understands that certain Proprietary Information may be highly sensitive and thus restricted by the U.S. government. Such restricted Proprietary Information may not be exported from the U.S. or communicated to any individual who is (i) not a U.S. citizen, (ii) not a U.S. permanent resident, or (iii) not a person who has been granted asylum or refugee status, unless an export license is first obtained from the U.S. Department of Commerce. To the extent Employee has access to such restricted Proprietary Information, Employee is responsible for becoming familiar and complying with Emergent policies and procedures related to Controlled Technology (as that term is defined in Title 15 CFR 734.2(b)(3)). Diversion of Controlled Technology contrary to U.S. law is strictly prohibited and may lead to civil or criminal sanctions. 3. Restrictive Covenants. No competition: During employment with Emergent, Employee shall not, directly or indirectly, either on Employee’s own account or for any person, firm, company, or other entity, whether or not for compensation, be engaged in or contribute to any business that

U.S. Version - November 2018 2 is engaged in any work or activities involving products, projects, initiatives, services, or other businesses competitive with or similar to those engaged in or offered by Emergent. No solicitation: During employment by Emergent and for a period of six months following any termination of Employee's employment for any reason (or any other different time period following the termination of employment established by written agreement between the Company and the Employee) (the “Restricted Period”), Employee shall not, directly or indirectly, either on Employee’s own account or for any other person, firm, company, or other entity: (a) solicit, interfere with, engage, hire or refer for hiring, employ, or endeavor to cause any employee, independent contractor, or vendor employed or engaged by Emergent to leave employment or terminate any contractual relationship or business relationship with Emergent, or induce or attempt to induce any such employee, independent contractor, or vendor to breach any employment agreement or contractual relationship that such employee, independent contractor, or vendor may have with Emergent; or (b) with the intent, purpose, or effect of interfering with Emergent’s business relationships, solicit, contact, or attempt to contact, contract with, or provide services to any “Customer” (defined below) or business partner of Emergent. Following the termination of Employee’s employment for any reason, Employee agrees to advise Emergent of Employee’s new employer, work location, and job responsibilities within ten days after accepting new employment, if that employer is engaged in any work or activity that involves a product, project, initiative, service or other business that is then competitive with or similar to a product, project, initiative, service, or business provided by Emergent. Employee further agrees to keep Emergent so advised of any change in employment during the Restricted Period in accordance with this Section. During the Restricted Period, Employee agrees that, upon the request of Emergent, Employee shall provide to his/her new employer a copy of this Agreement. 4. Intellectual Property Interests. Employee agrees promptly to disclose to Emergent (i) all ideas, inventions, discoveries, and technical developments, whether patentable or not, and (ii) all works of authorship, that Employee conceives or makes (alone or with others) during employment with Emergent, whether during working hours or not, and that (a) directly or indirectly relate in whole or in part to Emergent’s product lines, research and development activities, or field, technological, or industrial specialization; (b) directly or indirectly relate to matters within the scope of Employee’s duties or field of responsibility at Emergent; (c) are directly or indirectly based on Employee’s knowledge of the actual or anticipated business or interest of Emergent; (d) directly or indirectly relate to any project in which Employee is a participant in, whether at an Emergent location or not, that is either financed or directed by Emergent, or in which Employee uses any Emergent equipment, biological materials, or any other item of tangible or intangible Emergent property; or (e) are directly or indirectly aided by the use of time, materials, equipment, facilities or information of Emergent (collectively, “Employee Discoveries”). Employee Discoveries and Employee's interest in any patent, trade secret, copyright, data rights, or other intellectual property rights derivable from, resulting from, pertaining to, or relating to any of the Employee Discoveries are collectively referred to herein as “Work Product.” All Work Product shall be disclosed to Emergent within the time limits and in the format as provided by Emergent’s Corporate Policies and Global Business Operating Procedures. Reduction to practice after separation from employment shall not defeat Emergent’s rights in, or the Employee’s obligations with respect to, any Work Product. Employee shall promptly notify Emergent of the reduction to practice of any such Work Product during and after the term of this Agreement. Work Product belongs exclusively to Emergent and Employee hereby automatically assigns to Emergent, or its successor in interest, Employee's full right, title, and interest in

U.S. Version - November 2018 3 and to the Work Product as of its time of creation without any requirement of further consideration in all countries of the world. Without further compensation but at Emergent’s expense, Employee shall give all testimony, execute all documents necessary or otherwise required to perfect Emergent's right, title, and interest in and to the Work Product (including, but not limited to, executing declarations and/or assignments evidencing and/or confirming the assignment set forth in this Agreement), and, in general, do all lawful things requested by Emergent to enable Emergent to obtain, maintain, and enforce its rights in and to Work Product in the name of Emergent or its designee (as the case may be) in all countries of the world. If Emergent is unable because of Employee’s mental or physical incapacity or for any other reason to secure Employee’s signature to apply for or to pursue any application for any U.S. or foreign patents or copyright registrations covering Work Product, then Employee hereby irrevocably designates and appoints Emergent and its duly authorized officers and agents as its agent and attorney in fact in such matters. Accordingly, Emergent may in such a circumstance act for and on Employee’s behalf to execute and file any applications and do all other lawfully permitted acts to further the prosecution and issuance of patent or copyright registrations with the same legal force and effect as if executed by Employee. Any patent applications, patents, copyrighted works, and trademarks owned by Employee, as well as any patent applications, patents, copyrighted works, and trademarks invented or created by Employee and assigned to a former employer or other third party (collectively, “Prior Inventions”) are set forth on Exhibit A attached hereto and are excluded from the definition of Work Product. If no list is attached, Employee represents that there are no Prior Inventions. Emergent at its sole discretion, may, but is not obligated to, assign to Employee, any Work Product made by Employee that Emergent has no interest in exploiting. Any such assigned Work Product may be freely exploited by Employee as otherwise consistent with the terms of this Agreement. NOTICE TO EMPLOYEE: Consistent with applicable state law, and notwithstanding any other provision of this Agreement to the contrary, this Agreement does not obligate Employee to assign or offer to assign to Emergent any of Employee's rights in an invention for which no equipment, property, supplies, facilities, resources, or trade secret information of Emergent was used and that was developed entirely on Employee's own time, unless (a) the invention relates (i) directly to the business of Emergent, or (ii) to Emergent’s actual or demonstrably anticipated research or development; or (b) the invention results from any work performed by Employee for Emergent. 5. Personal Electronic Equipment. Employee shall comply with the provisions of the Company’s Acceptable Systems Use Policy, as it may be amended from time to time. Employee shall not transmit or maintain Proprietary Information in any non-Emergent sponsored or operated electronic communication system, including, but not limited to, personal e-mail (such as gmail, yahoo mail, etc.), text message (e.g. iMessage, WhatsApp, Facebook Messenger, etc.), and Twitter. Employee hereby acknowledges that all Proprietary Information that may be contained on personal electronic equipment including, but not limited to, laptop computers, personal data assistants, calendars, day-timers, cell phones, pagers, or other electronic devices, is the exclusive property of Emergent. In addition to Employee’s obligations under the Acceptable Systems Use Policy, Employee hereby agrees to make Employee's personal electronic equipment containing Proprietary Information immediately available to Emergent for review and inspection upon request and to allow Emergent to inspect and/or recover any Emergent information stored or otherwise maintained therein. If Employee possesses personal electronic equipment that is not located on Emergent premises,

U.S. Version - November 2018 4 Employee hereby agrees immediately to deliver such personal electronic equipment to Emergent upon its request. 6. Definitions. “Proprietary Information” means any confidential information of Emergent and any confidential information that is learned or acquired by Emergent from others, including others with whom Emergent has a business relationship. Proprietary Information includes, but is not limited to, Work Product (as defined herein), research data and plans; information relating to products (including plans, technical specifications, formulations, methods, and techniques); information relating to projects and initiatives (including plans, technical specifications, formulations, methods, and techniques); customer information, regardless of whether such customer information is subject to a non-disclosure or equivalent agreement; designs and drawings (including engineering, equipment and building designs and drawings); sales and/or marketing plans and strategy; pricing and costing plans; finance information; compensation, employee performance, and other personnel information; hardware configuration information; software; and other non-public information relating to the business of Emergent. Proprietary Information does not include information that is or has become publicly known and made generally available through no wrongful act of Employee or others who were not under confidentiality obligations to Emergent. “Affiliate Entity” means any direct, indirect, current, or future subsidiary of Emergent or any other entity controlled by, under common control with, or that controls Emergent BioSolutions Inc., including a parent. “Customer” means those customers, collaborators, clients, vendors, suppliers, persons, or entities (as well as their subsidiaries and/or affiliates) who have purchased goods or services from Emergent, or who have rendered services to or in conjunction with Emergent, or who have contacted Emergent or been contacted or solicited by Emergent for the purchase of goods or services, at any time within the 24 months preceding the date of termination of Employee’s employment. The terms “use” and “disclose” include, but are not limited to, copying, selling, licensing, distributing, transmitting, reverse engineering, decompiling, disassembling, or transferring. 7. Costs of Enforcement. In the event of any legal action stemming from an alleged breach of this Agreement, the prevailing party shall be entitled to recover all costs and expenses, including reasonable attorneys' fees, incurred in enforcing or attempting to enforce (if successful) any of the terms, covenants, or conditions of this Agreement, including costs incurred prior to commencement of any legal action (including, but not limited to, mutually agreed-upon arbitration) and all costs and expenses, including reasonable attorneys' fees, incurred in any appeal from any action brought to enforce any of said terms, covenants, or conditions. 8. Injunctive Relief. Employee expressly acknowledges that violations of Sections 2, 3, 4, or 5 will cause immediate, substantial, and irreparable harm to Emergent for which monetary damages alone would not be a sufficient remedy. In the event of a breach of this Agreement, Employee agrees that Emergent shall be entitled to an injunction in any court of competent jurisdiction restraining all further acts restricted by this Agreement without the need of a bond or a showing of active damages. This injunctive remedy is in addition to any other rights that Emergent may have in law or equity, including the right to mutually agreed-upon arbitration.

U.S. Version - November 2018 5 9. Reporting Possible Violations of Law. Nothing in this Agreement prohibits Employee from filing a charge with or reporting possible violations of law or regulation to any governmental agency or entity or of making any other disclosures that are protected under the whistleblower provisions of any law or regulation. Under the federal Defend Trade Secrets Act of 2016, Employee shall not be held criminally or civilly liable under any federal or state trade secret law for the disclosure of a trade secret that: (a) is made (i) in confidence to a federal, state, or local government official, either directly or indirectly, or to an attorney; and (ii) solely for the purpose of reporting or investigating a suspected violation of law; or (b) is made to Employee’s attorney in relation to a lawsuit for retaliation against Employee for reporting a suspected violation of law; or (c) is made in a complaint or other document filed in a lawsuit or other proceeding, if such filing is made under seal. 10. Governing Law, Venue, and Waiver of Jury Trial.

No Waiver/Severability. No waiver of any of the provisions of this Agreement shall be deemed or shall constitute a waiver of any other provision hereof, nor shall such a waiver constitute a continuing waiver. If any provision or provisions of this Agreement are determined to be unenforceable, the remaining provisions shall stand and be interpreted pursuant to the laws of the State of Maryland. The failure of any Party at any time or times to require performance of any provision hereof shall in no manner affect the right of such Party at a later time to enforce such provision or any other provision of this Agreement. 13. Counterparts/Form of Agreement. This Agreement may be signed in two identical copies, each of which shall be deemed an original copy, and a facsimile or other electronically-transmitted copy shall constitute a legally binding, enforceable document. 14.

This Agreement shall not be construed as an agreement by Emergent to employ Employee for any specific period of time and shall not change Employee’s status as an “at will” employee (meaning that such employment may be terminated by either party at any time, for any reason, with or without cause) or in any way modify a term of employment contained in any specific written employment agreement that may have been entered into between Employee and Emergent separate from this Agreement.
