			Re:Separation Agreement
		

		
			 
		

		
			Dear Barry:
		

		
			 
		

		
			This letter agreement (the “Agreement”) sets forth the terms of the separation package that MobileIron, Inc. (the “Company”) is offering to you in connection with the termination of your employment.  
		

			
	
			
				 1.
			Separation Date.   Your last day of service as President, Chief Executive Officer, and Director with the Company is October 16, 2017 (the "End of Service Date"), and your employment termination date will be October 31, 2017 (the "Separation Date"). As of the End of Service Date, you will cease to be an officer of the Company and its affiliates, you hereby resign from your official titled positions (including but not limited to President, Chief Executive Officer and Director) and you will cease to be a "Section 16 officer" (as determined for purposes of the Securities and Exchange Act of 1934, as amended).  On the Separation Date, you will experience a "separation from service" (as such term is defined under Treasury Regulation Section 1.409A-1(h), without regard to any alternate definitions thereunder, a "Separation from Service").  Between the End of Service Date and the Separation Date, you will remain as an employee of the Company and shall, upon reasonable request, provide transition assistance to the new CEO.

			
	
			
				 2.
			Accrued Salary and Paid Time Off.  On the Separation Date, the Company will pay you all accrued salary, and all accrued and unused vacation earned through the Separation Date, subject to standard payroll deductions and withholdings.  You are entitled to receive these payments regardless of whether or not you sign this Agreement. 

			
	
			
				 3.
			Severance Benefits.  Provided you sign this Agreement, allow it to become effective within the time period set forth below, and otherwise observe your obligations set forth in this Agreement and in your Executive Employment Agreement with the Company, effective as of January 6, 2016 (the “Employment Agreement”), the Company will provide you with the Severance Benefits as set forth in the Employment Agreement, in full satisfaction of its obligations to you under such agreement.  You and the Company agree that the pro rata Annual Bonus amount due under the Employment Agreement is $405,513 and that it will be paid on or before March 15, 2018 when other executive bonuses are paid.

			
	
			
				 4.
			Health Insurance; Other Benefits.  

			
	
			
				 (a)
			COBRA.  To the extent permitted by the federal COBRA law or applicable state insurance laws (collectively, “COBRA”), and by the Company’s current group health insurance policies, you will be eligible to continue your group health insurance benefits at your own expense and later to convert to an individual policy if you wish.  You will be provided with a separate notice regarding your health insurance continuation rights under COBRA within the time period required by law.  

		
			

		 

 

		

			
	
			
				 (b)
			Other Benefits.  Your eligibility to continue as a participant in all other Company provided benefit plans will terminate on the Separation Date.

			
	
			
				 5.
			Stock Options; RSUs.  Your Company issued stock options  (the “Stock Options”) and restricted stock unit awards (the “RSUs”) will cease vesting on the Separation Date, after taking into account any vesting acceleration provided as a Severance Benefit. The last date to exercise vested Stock Options would be January 31, 2018 under the standard terms of the Company’s equity plans, but that date will be extended to October 31, 2018 if you sign this agreement. You acknowledge and agree that all unvested Stock Options  and RSUs, after taking into account such vesting acceleration will be forfeited on the Separation Date. 

			
	
			
				 6.
			Confidential Information and Inventions.  You acknowledge and reaffirm your continuing obligations under your signed MobileIron, Inc. Confidential Information and Invention Assignment Agreement (the “Confidentiality Agreement,” a copy of which is attached hereto as Exhibit A) and which is incorporated herein by reference.  As required by the Confidentiality Agreement, you agree to sign and return to the Company the Termination Certification, which is attached as Exhibit C to the Confidentiality Agreement.

			
	
			
				 7.
			No Other Compensation or Benefits.  You acknowledge that, except as expressly provided in this Agreement, you have not earned and will not receive from the Company any additional compensation, severance, or benefits on or after the Separation Date, with the exception of any vested right you may have under the express terms of a written ERISA-qualified benefit plan (e.g., 401(k) account).  By way of example, you acknowledge that you have not earned and are not owed any equity, bonus, incentive compensation, severance benefits, or commissions.

			
	
			
				 8.
			Expense Reimbursements.  You agree that, within thirty (30) days of the Separation Date, you will submit your final documented expense reimbursement statement reflecting all business expenses you incurred through the Separation Date, if any, for which you seek reimbursement.  The Company will reimburse you for these expenses pursuant to its regular business practice.

			
	
			
				 9.
			Return of Company Property.    You acknowledge that you have returned to the Company all Company documents (and all copies thereof) and other Company property that was in your possession or control, including, but not limited to, Company files, notes, financial and operational information, customer lists and contact information, product and services information, research and development information, drawings, records, plans, forecasts, reports, payroll information, spreadsheets, studies, analyses, compilations of data, proposals, agreements, sales and marketing information, personnel information, specifications, code, software, databases, computer-recorded information, tangible property and equipment (including, but not limited to, computers, facsimile machines, mobile telephones, tablets, servers and other handheld devices), credit cards, entry cards, identification badges and keys; and any materials of any kind which contain or embody any proprietary or confidential information of the Company and all reproductions thereof in whole or in part and in any medium.  You agree that you have made a diligent search to locate any such documents, property and information.  In addition, if you have used any personally owned computer, server, or e-mail system to receive, store, review, prepare or transmit any confidential or proprietary data, materials or information of the Company, then within two (2) business days following the Separation Date, you must provide the Company with a computer-useable copy of such information and then permanently delete and expunge such confidential or proprietary information from those systems without retaining any reproductions (in whole or in part); and you agree to provide the Company access to your system, as requested, to verify that the necessary copying and deletion is done. Your timely compliance with the provisions of this Section is a precondition to your receipt of the severance benefits provided hereunder.

		
			

		 

 

		

			
	
			
				 10.
			Nondisparagement.  You agree not to disparage the Company or the Company’s officers, directors, employees, shareholders, parents, subsidiaries, and affiliates, in any manner likely to be harmful to them or their business, business reputation or personal reputation, and the Company agrees (through its officers and directors)  not to disparage you in any manner likely to be harmful to your business reputation or personal reputation; provided that both you and the Company may respond accurately and fully to any question, inquiry or request for information when required by legal process.  

			
	
			
				 11.
			Cooperation and Assistance.  You agree that you will not voluntarily provide assistance, information or advice, directly or indirectly (including through agents or attorneys), to any person or entity in connection with any claim or cause of action of any kind brought against the Company, nor will you induce or encourage any person or entity to bring such claims.  However, it will not violate this Agreement if you testify truthfully when required to do so by a valid subpoena or under similar compulsion of law.  Further, you agree to voluntarily cooperate with the Company, if you have knowledge of facts relevant to any threatened or pending claim, investigation, audit or litigation against or by the Company, by making yourself reasonably available without further compensation for interviews with the Company or its legal counsel, preparing for and providing truthful and accurate deposition and trial testimony.

			
	
			
				 12.
			No Admissions.  The promises and payments in consideration of this Agreement will not be construed to be an admission of any liability or obligation by either party to the other party, and neither party makes any such admission.

			
	
			
				 13.
			Release of Claims.  

			
	
			
				 (a)
			General Release.  In exchange for the consideration provided to you under this Agreement to which you would not otherwise be entitled, you hereby generally and completely release the Company, and its affiliated, related, parent and subsidiary entities, and its and their current and former directors, officers, employees, shareholders, partners, agents, attorneys, predecessors, successors, insurers, affiliates, and assigns (collectively, the “Released Parties”) from any and all claims, liabilities and obligations, both known and unknown, that arise out of or are in any way related to events, acts, conduct, or omissions occurring prior to or on the date you sign this Agreement (collectively, the “Released Claims”).

				 (d)
			Waiver of Unknown Claims.  In giving the releases set forth in this Agreement, which include claims which may be unknown to you at present, you acknowledge that you have read and understand Section 1542 of the California Civil Code which reads as follows: “A general release does not extend to claims which the creditor does not know or suspect to exist in his or her favor at the time of executing the release, which if known by him or her must have materially affected his or her settlement with the debtor.”  You hereby expressly waive and relinquish all rights and benefits under that section and any law or legal principle of similar effect in any jurisdiction with respect to your release of claims herein, including but not limited to the release of unknown and unsuspected claims.

			
	
			
				 (e)
			Excluded Claims.  Notwithstanding the foregoing, the following are not included in the Released Claims (the “Excluded Claims”): (i) any rights or claims for indemnification you may have pursuant to any written indemnification agreement with the Company to which you are a party, under the charter or bylaws of the Company, under applicable law or under policy of insurance; (ii) any rights which cannot be waived as a matter of law; and (iii) any claims for breach of this Agreement.

				 16.
			Miscellaneous.  This Agreement, including Exhibit A, constitutes the complete, final and exclusive embodiment of the entire agreement between you and the Company with regard to the subject matter hereof.  It is entered into without reliance on any promise or representation, written or oral, other than those expressly contained herein, and it supersedes any other agreements, promises, warranties or representations concerning its subject matter.  This Agreement may not be modified or amended except in a writing signed by both you and a duly authorized officer of the Company.

EXHIBIT A
		

		
			 
		

		
			CONFIDENTIAL INFORMATION AND INVENTION ASSIGNMENT AGREEMENT 
		

		
			As a condition of my becoming employed (or my employment being continued) by Mobile Iron, Inc., a Delaware corporation (the “Company”), and in consideration of my employment relationship with the Company and my receipt of the compensation now and hereafter paid to me by the Company, I agree to the following:
		

		
			 
		

		
			1.       Employment  Relationship.  I understand and acknowledge that this Agreement does not alter, amend or expand upon (i) any rights I may have to continue in the employ of, or (ii) the duration of my employment relationship with, the Company under any existing agreements between the Company and me or under applicable law.  Any employment relationship between the Company and me, whether commenced prior to or upon the date of this Agreement, shall be referred to herein as the “Relationship.”
		

		
			 
		

		
			2.       At-Will Relationship.  I understand and acknowledge that the Relationship is and shall continue to be at-will, meaning that either I or the Company may terminate the Relationship at any time and for any reason, with or without cause or advance notice.
		

		
			 
		

		
			3.       Confidential Information.
		

		
			 
		

		
			(a)      Company Information.  I agree at all times during the Relationship and thereafter, to hold in strictest confidence, and not to use, except for the benefit of the Company to the extent necessary to perform my obligations to the Company under the Relationship, or to disclose to any person, firm, corporation or other entity without written authorization of the Board of Directors of the Company, any Confidential Information of the Company which I obtain or create.  I further agree not to make copies of such Confidential Information except as authorized by the Company.  I understand that “Confidential Information” means any Company proprietary information, technical data, trade secrets or know-how, including, but not limited to, research, product plans, products, services, suppliers, customer lists and customers (including, but not limited to, customers of the Company on whom I called or with whom I became acquainted during the Relationship), prices and costs, markets, software, developments, inventions, laboratory notebooks, processes, formulas, technology, designs, drawings, engineering, hardware configuration information, marketing information, licenses, financial information, budgets, information regarding the skills and compensation of the Company’s employees, contractors, and any other service providers of the Company or other business information disclosed to me by the Company either directly or indirectly in writing, orally or by drawings or observation of parts or equipment or created by me during the Relationship, whether or not during working hours.  I understand that Confidential Information includes, but is not limited to, information pertaining to any aspect of the Company’s business which is either information not known by actual or potential competitors of the Company or other third parties not under confidentiality obligations to the Company, or is otherwise proprietary information of the Company or its customers or suppliers, whether of a technical nature or otherwise.  I further understand that Confidential Information does not include any of the foregoing items which has become publicly and widely known and made generally available through no wrongful act of mine or of others who were under confidentiality obligations as to the item or items involved.
		

		
			 
		

		
			(b)      Prior Obligations.  I represent that my performance of all terms of this Agreement as an employee of the Company has not breached and will not breach any agreement with any former employer or other party, including any agreement to keep in confidence proprietary information, knowledge or data acquired by me prior or subsequent to the commencement of the Relationship, and I will not disclose to the Company or use any inventions, confidential or non-public proprietary information or material belonging to any current or former client or employer or any other party.  I will not induce the Company to use any 

		 

 

inventions, confidential or non-public proprietary information, or material belonging to any current or former client or employer or any other party.
		

		
			 
		

		
			(c)      Third Party Information.  I recognize that the Company has received and in the future will receive confidential or proprietary information from third parties subject to a duty on the Company’s part to maintain the confidentiality of such information and to use it only for certain limited purposes.  I agree to hold all such confidential or proprietary information in the strictest confidence and not to disclose it to any person, firm or corporation or to use it except as necessary in carrying out my work for the Company consistent with the Company’s agreement with such third party.
		

		
			 
		

		
			4.       Inventions.
		

		
			 
		

		
			(a)      Inventions Retained and Licensed.  I have attached hereto, as Exhibit A, a list describing with particularity all inventions, original works of authorship, developments, improvements, and trade secrets which were made by me prior to the commencement of the Relationship (collectively referred to as “Prior Inventions”), which belong solely to me or belong to me jointly with another, which relate in any way to any of the Company’s proposed businesses, products or research and development, and which are not assigned to the Company hereunder; or, if no such list is attached, I represent that there are no such Prior Inventions.  If, in the course of the Relationship, I incorporate into a Company product, process or machine a Prior Invention owned by me or in which I have an interest, the Company is hereby granted and shall have a non-exclusive, royalty-free, irrevocable, perpetual, worldwide license (with the right to sublicense) to make, have made, copy, modify, make derivative works of, use, sell and otherwise distribute such Prior Invention as part of or in connection with such product, process or machine.
		

		
			 
		

		
			(b)      Assignment of Inventions.  I agree that I will promptly make full written disclosure to the Company, will hold in trust for the sole right and benefit of the Company, and hereby assign to the Company, or its designee, all my right, title and interest throughout the world in and to any and all inventions, original works of authorship, developments, concepts, know-how, improvements or trade secrets, whether or not patentable or registrable under copyright or similar laws, which I may solely or jointly conceive or develop or reduce to practice, or cause to be conceived or developed or reduced to practice, during the Relationship (collectively referred to as “Inventions”), except as provided in Section 4(e) below.  I further acknowledge that all Inventions which are made by me (solely or jointly with others) within the scope of and during the Relationship are “works made for hire” (to the greatest extent permitted by applicable law) and are compensated by my salary, unless regulated otherwise by the mandatory law of the state of California.  Any assignment of Inventions (and all intellectual property rights with respect thereto) hereunder includes an assignment of all moral rights.  To the extent such moral rights cannot be assigned to the Company and to the extent the following is allowed by the laws in any country where moral rights exist, I hereby unconditionally and irrevocably waive the enforcement of such moral rights, and all claims and causes of action of any kind against the Company or related to the Company’s customers, with respect to such rights.  I further acknowledge and agree that neither my successors-in-interest nor legal heirs retain any moral rights in any Inventions (and any intellectual property rights with respect thereto).
		

		
			 
		

		
			(c)      Maintenance of Records.  I agree to keep and maintain adequate and current written records of all Inventions made by me (solely or jointly with others) during the Relationship.  The records may be in the form of notes, sketches, drawings, flow charts, electronic data or recordings, laboratory notebooks, and any other format.  The records will be available to and remain the sole property of the Company at all times.  I agree not to remove such records from the Company’s place of business except as expressly permitted by Company policy which may, from time to time, be revised at the sole election of the Company for the purpose of furthering the Company’s business.  I agree to return all such records 

		 

 

(including any copies thereof) to the Company at the time of termination of the Relationship as provided for in Section 5.
		

		
			 
		

		
			(d)      Patent and Copyright Rights.  I agree to assist the Company, or its designee, at its expense, in every proper way to secure the Company’s, or its designee’s, rights in the Inventions and any copyrights, patents, trademarks, mask work rights, moral rights, or other intellectual property rights relating thereto in any and all countries, including the disclosure to the Company or its designee of all pertinent information and data with respect thereto, the execution of all applications, specifications, oaths, assignments, recordations, and all other instruments which the Company or its designee shall deem necessary in order to apply for, obtain, maintain and transfer such rights, or if not transferable, waive such rights, and in order to assign and convey to the Company or its designee, and any successors, assigns and nominees the sole and exclusive rights, title and interest in and to such Inventions, and any copyrights, patents, mask work rights or other intellectual property rights relating thereto.  I further agree that my obligation to execute or cause to be executed, when it is in my power to do so, any such instrument or papers shall continue after the termination of this Agreement until the expiration of the last such intellectual property right to expire in any country of the world.  If the Company or its designee is unable because of my mental or physical incapacity or unavailability or for any other reason to secure my signature to apply for or to pursue any application for any United States or foreign patents, copyright, mask works or other registrations covering Inventions or original works of authorship assigned to the Company or its designee as above, then I hereby irrevocably designate and appoint the Company   and its duly authorized officers and agents as my agent and attorney in fact, to act for and in my behalf and stead to execute and file any such applications and to do all other lawfully permitted acts to further the application for, prosecution, issuance, maintenance or transfer of letters patent, copyright or other registrations thereon with the same legal force and effect as if originally executed by me.  I hereby waive and irrevocably quitclaim to the Company or its designee any and all claims, of any nature whatsoever, which I now or hereafter have for infringement of any and all proprietary rights assigned to the Company or such designee.
		

		
			 
		

		
			(e)      Exception to Assignments.  I understand that the provisions of this Agreement requiring assignment of Inventions to the Company do not apply to any invention which qualifies fully under the provisions of California Labor Code Section 2870 (attached hereto as Exhibit B).  I will advise the Company promptly in writing of any inventions that I believe meet such provisions and are not otherwise disclosed on Exhibit A.
		

		
			 
		

		
			(f)       Government or Third Party.  I agree that, as directed by the Company, I will assign to a third party, including without limitation the United States, all my right, title, and interest in and to any particular Company Invention.
		

		
			 
		

		
			5.       Company Property; Returning Company Documents.  I acknowledge and agree that I have no expectation of privacy with respect to the Company’s telecommunications, networking or information processing systems (including, without limitation, stored company files, e-mail messages and voice messages) and that my activity and any files or messages on or using any of those systems may be monitored at any time without notice.  I further agree that any property situated on the Company’s premises and owned by the Company, including disks and other storage media, filing cabinets or other work areas, is subject to inspection by Company personnel at any time with or without notice.  I agree that, at the time of termination of the Relationship, I will deliver to the Company (and will not keep in my possession, recreate or deliver to anyone else) any and all devices, records, data, notes, reports, proposals, lists, correspondence, specifications, drawings, blueprints, sketches, laboratory notebooks, materials, flow charts, equipment, other documents or property, or reproductions of any of the aforementioned items developed by me pursuant to the Relationship or otherwise belonging to the Company, its successors or assigns.  In the event of the termination of the Relationship, I agree to sign and deliver the “Termination 

		 

 

Certification” attached hereto as Exhibit C; however, my failure to sign and deliver the Termination Certificate shall in no way diminish my continuing obligations under this Agreement.
		

		
			 
		

		
			6.       Notification to Other Parties.
		

		
			 
		

		
			(a)      Employees.  In the event that I leave the employ of the Company, I hereby consent to notification by the Company to my new employer about my rights and obligations under this Agreement.
		

		
			 
		

		
			(b)      Consultants.  I hereby grant consent to notification by the Company to any other parties besides the Company with whom I maintain a consulting relationship, including parties with whom such relationship commences after the effective date of this Agreement, about my rights and obligations under this Agreement.
		

		
			 
		

		
			7.       Solicitation of Employees, Consultants and Other Parties.  I agree that during the Relationship and for a period of twenty-four (24) months immediately following the termination of the Relationship for any reason, whether with or without cause, I shall not either directly or indirectly solicit, induce, recruit or encourage any of the Company’s employees or consultants to terminate their relationship with the Company, or attempt to solicit, induce, recruit, encourage or take away employees or consultants of the Company, either for myself or for any other person or entity.  Further, during the Relationship and at any time following termination of the Relationship for any reason, with or without cause, I shall not use any Confidential Information of the Company to attempt to negatively influence any of the Company’s clients or customers from purchasing Company products or services or to solicit or influence or attempt to influence any client, customer or other person either directly or indirectly, to direct his or its purchase of products and/or services to any person, firm, corporation, institution or other entity in competition with the business of the Company.
		

		
			 
		

		
			8.       Representations and Covenants.
		

		
			 
		

		
			(a)      Facilitation of Agreement.  I agree to execute promptly any proper oath or verify any proper document required to carry out the terms of this Agreement upon the Company’s written request to do so.
		

		
			 
		

		
			(b)      Conflicts.  I represent that my performance of all the terms of this Agreement does not and will not breach any agreement I have entered into, or will enter into with any third party, including without limitation any agreement to keep in confidence proprietary information acquired by me in confidence or in trust prior to commencement of my Relationship with the Company.  I agree not to enter into any written or oral agreement that conflicts with the provisions of this Agreement.
		

		
			 
		

		
			(c)      Voluntary Execution.  I certify and acknowledge that I have carefully read all of the provisions of this Agreement and that I understand and will fully and faithfully comply with such provisions.
		

		
			 
		

		
			9.       General Provisions.
		

		
			 
		

		
			(a)      Governing Law.  The validity, interpretation, construction and performance of this Agreement shall be governed by the laws of the State of California, without giving effect to the principles of conflict of laws.
		

		
			 
		

		
			(b)      Entire Agreement.  This Agreement sets forth the entire agreement and understanding between the Company and me relating to the subject matter herein and merges all prior discussions between us.  No modification or amendment to this Agreement, nor any waiver of any rights under this Agreement, will be effective unless in writing signed by both parties.  Any subsequent change or changes in my duties, obligations, rights or compensation will not affect the validity or scope of this Agreement.

EXECUTION VERSION 

REGISTRATION RIGHTS AGREEMENT 

This REGISTRATION RIGHTS AGREEMENT, dated as of November 3, 2017 (this “Agreement”), is made among Cempra, Inc., a
Delaware corporation (the “Company”), Vatera Healthcare Partners LLC, a Delaware limited liability company (the “Vatera Shareholder”), and the other shareholders of the Company set forth on the signature
pages hereto (the “Other Shareholders” and, together with the Vatera Shareholder, the “Shareholders” or individually a “Shareholder”). 

A. On August 8, 2017, the Company, Castle Acquisition Corp., a Delaware corporation and wholly owned subsidiary of the Company
(“Merger Sub”) and Melinta Therapeutics, Inc., a Delaware corporation (“Melinta”), entered into an Agreement and Plan of Merger and Reorganization (as amended on each of September 6, 2017 and October 24,
2017, and as may be further amended from time to time, the “Merger Agreement”), pursuant to which Merger Sub merged with and into Melinta, with Melinta as the surviving company and a wholly owned subsidiary of the Company (the
“Merger”). 
 B. In connection with the Merger and pursuant to the Merger Agreement the Shareholders acquired Castle Common
Stock (as defined in the Merger Agreement) (“Company Common Stock”). 
 C. In order to induce the Shareholders to adopt and
approve the Merger Agreement and approve the Merger and other transactions contemplated in the Merger Agreement, the Company has agreed to provide the registration rights set forth in this Agreement. 

D. Capitalized terms used in this Agreement and set forth in Section 9 are used as defined in Section 9. 

Now, therefore, the parties hereto agree as follows: 

1. Mandatory Shelf Registration. 

(a) The Company agrees to file with the SEC as soon as reasonably practicable, but in no event later than 90 calendar days following the date
hereof, a shelf Registration Statement on Form S-3 or such other form under the Securities Act then available to the Company providing for the resale pursuant to Rule 415 from time to time by the Vatera
Shareholder of any and all Registrable Securities held by the Vatera Shareholder (the “Mandatory Shelf Registration Statement”). The Company agrees to use its commercially reasonable efforts to cause the Mandatory Shelf Registration
Statement to be declared effective by the SEC within 90 calendar days after the initial date of filing thereof. 
 (b) The Company shall use
its commercially reasonable efforts to cause the Mandatory Shelf Registration Statement to remain continuously effective until the earliest of (A) the sale pursuant to a registration statement of all of the Registrable Securities covered by the
Mandatory Shelf Registration Statement, (B) the sale, transfer or other disposition pursuant to Rule 144 of all of the Registrable Securities covered by the Mandatory Shelf Registration 

 
Statement, (C) such time as the Registrable Securities covered by the Mandatory Shelf Registration Statement that are not held by Affiliates of the Company are, in the opinion of counsel to
the Company, eligible for resale pursuant to Rule 144 so long as the Company is current in its 1934 Act reporting, if so required by Rule 144, (D) such time as all of the Registrable Securities covered by the Mandatory Shelf Registration Statement
have been sold to the Company or any of its subsidiaries or (E) the fifth anniversary of the effective date of the Mandatory Shelf Registration Statement. The Mandatory Shelf Registration Statement shall provide for the resale of Registrable
Securities from time to time, and pursuant to any method or combination of methods legally available to, and requested by, the Vatera Shareholder. The Company will pay all Registration Expenses incurred in connection with any registration pursuant
to this Section 1. 
 (c) If the Vatera Shareholder intends to distribute Registrable Securities under the Mandatory Shelf Registration
Statement by means of an underwritten offering, the Vatera Shareholder will so advise the Company. In such event, the Vatera Shareholder will have the right to select one bookrunner for the offering, provided that such bookrunner is reasonably
satisfactory to the Company. In connection with each underwritten resale of Registrable Securities under the Mandatory Shelf Registration Statement, the Company shall cause there to be Full Cooperation. The Vatera Shareholder shall be entitled to no
more than two underwritten offerings under the Mandatory Shelf Registration Statement; and in no event shall the Vatera Shareholder be entitled to request an underwritten offering until after the six month anniversary of the date hereof. 

2. Piggyback Registrations. 

(a) Right to Piggyback. At any time after the date hereof, whenever the Company proposes to register shares of Company Common Stock
(“Common Shares”) (other than pursuant to (i) registrations on Form S-8 or any similar form(s) solely for registration of securities in connection with an employee benefit plan or
dividend reinvestment plan, (ii) registrations on Form S-4 or any similar form(s) solely for registration of securities in connection with a business combination, or (iii) a Mandatory Shelf
Registration Statement), whether for its own account or for the account of one or more securityholders of the Company, and the registration form to be filed may be used for the registration or qualification for distribution of Registrable
Securities, the Company will give prompt written notice to the Shareholders of its intention to effect such a registration and will include in such registration all Registrable Securities with respect to which the Company has received a written
request for inclusion therein within 15 days after the date of the Company’s notice (a “Piggyback Registration”). Once a Shareholder has made such a written request, it may withdraw its Registrable Securities from such
Piggyback Registration by giving written notice to the Company and the managing underwriter, if any, on or before the fifth (5th) day prior to the anticipated effective date of such Piggyback Registration. The Company may terminate or withdraw any
registration initiated by it and covered by this Section 2 prior to the effectiveness of such registration, whether or not any Shareholder has elected to include Registrable Securities in such registration, and except for the obligation to pay
Registration Expenses pursuant to Section 2(c) the Company will have no liability to the Shareholders in connection with such termination or withdrawal. 

  
 - 2 - 

 (b) Underwritten Registration. If the registration referred to in Section 2(a) is
proposed to be underwritten, the Company will so advise the Shareholders in the written notice given pursuant to Section 2(a). In such event, the right of any Shareholder to registration pursuant to this Section 2 will be conditioned upon
such Shareholder’s participation in such underwriting and the inclusion of such Shareholder’s Registrable Securities in the underwriting, and each such Shareholder will (together with the Company and the other holders distributing their
securities through such underwriting) enter into an underwriting agreement in customary form with the underwriter or underwriters selected for such underwriting by the Company. If any such Shareholder disapproves of the terms of the underwriting, it
may elect to withdraw therefrom by written notice to the Company and the managing underwriter. 
 (c) Piggyback Registration Expenses.
Except to the extent prohibited by applicable law, the Company will pay all Registration Expenses in connection with any Piggyback Registration, whether or not any registration or prospectus becomes effective or final. 

(d) Priority on Primary Registrations. If a Piggyback Registration relates to an underwritten primary offering on behalf of the Company,
and the managing underwriters advise the Company that in their opinion the number of securities requested to be included in such registration exceeds the number which can be sold without adversely affecting the marketability of the offering,
including the price at which such securities can be sold, the Company will include in such registration the maximum number of securities that in the opinion of such underwriters can be sold without adversely affecting the marketability of the
offering, including the price at which such securities can be sold, which securities will be so included in the following order of priority: (i) first, the securities the Company proposes to sell, (ii) second, the Registrable Securities
and Prior Holder Securities requested to be included in such registration, pro rata among the Shareholders and the Prior Holders of such securities on the basis of the number of Registrable Securities and Prior Holder Securities so requested to be
included therein owned by each such holder or in such other manner as they may agree, and (iii) third, other securities requested to be included in such registration. 

(e) Priority on Secondary Registrations. If a Piggyback Registration relates solely to an underwritten secondary registration on behalf
of other holders of the Company’s securities, and the managing underwriters advise the Company that in their opinion the number of securities requested to be included in such registration exceeds the number which can be sold without adversely
affecting the marketability of the offering, including the price at which such securities can be sold, the Company will include in such registration the maximum number of securities that in the opinion of such underwriters can be sold without
adversely affecting the marketability of the offering, including the price at which such securities can be sold, which securities will be so included in the following order of priority: (i) first, (A) the securities requested to be included
therein by the holders requesting such registration and (B) the Registrable Securities and Prior Holder Securities pro rata among the holders thereof on the basis of the number of securities so requested to be included therein owned by each
such holder or in such other manner as they may agree, and (iii) third, other securities requested to be included in such registration.

 3. Registration Procedures. Whenever a Shareholder has requested that any
Registrable Securities be registered pursuant to this Agreement (or in connection with the Mandatory Shelf Registration Statement), the Company will use its commercially reasonable efforts to effect the registration and sale of such Registrable
Securities in accordance with the intended method of disposition thereof. Without limiting the generality of the foregoing, the Company will, as expeditiously as commercially reasonable: 

(a) prepare and (except with respect to the Mandatory Shelf Registration Statement) file with the SEC a Registration Statement with respect to
such Registrable Securities, make all required filings with the National Association of Securities Dealers and thereafter use its commercially reasonable efforts to cause such Registration Statement to become effective; provided, that before filing
a Registration Statement or any amendments or supplements thereto, the Company will furnish to one firm of counsel selected by the Vatera Shareholder copies of all such documents proposed to be filed. The Company will not file any Registration
Statement or amendment or post-effective amendment or supplement to such Registration Statement to which such counsel will have reasonably objected in writing on the grounds that such amendment or supplement does not comply in all material respects
with the requirements of the 1933 Act or of the rules or regulations thereunder; 
 (b) prepare and file with the SEC such amendments and
supplements to such Registration Statement as may be necessary to keep such Registration Statement effective for a period of either (i) not less than six months or, if such Registration Statement relates to an underwritten offering, such longer
period as in the opinion of counsel for the underwriters a prospectus is required by law to be delivered in connection with sales of Registrable Securities by an underwriter or dealer or (ii) such shorter period as will terminate when all of
the securities covered by such Registration Statement have been disposed of in accordance with the intended methods of disposition by the Shareholders set forth in such Registration Statement (but in any event not before the expiration of any longer
period required under the 1933 Act), and to comply with the provisions of the 1933 Act with respect to the disposition of all securities covered by such Registration Statement until such time as all of such securities have been disposed of in
accordance with the intended methods of disposition by the Shareholders set forth in such Registration Statement; 
 (c) furnish to the
Shareholders such number of copies, without charge, of such Registration Statement, each amendment and supplement thereto, including each preliminary prospectus, final prospectus, all exhibits and other documents filed therewith and such other
documents as the Shareholders may reasonably request in order to facilitate the disposition of the Registrable Securities owned by the Shareholders; 

(d) use its commercially reasonable efforts to register or qualify such Registrable Securities under such other securities or blue sky laws of
such jurisdictions as the Shareholders reasonably request and do any and all other acts and things that may be necessary or reasonably advisable to enable the Shareholders to consummate the disposition in such jurisdictions of the Registrable
Securities owned by the Shareholders (provided, that the Company will not be required to (i) qualify generally to do business in any jurisdiction where it would not otherwise be required to qualify but for this subsection, (ii) subject
itself to taxation in any such jurisdiction or (iii) consent to general service of process in any such jurisdiction); 

  
 - 4 - 

 (e) use its commercially reasonable efforts to cause all Registrable Securities covered by such
Registration Statement to be registered with or approved by such other governmental agencies, authorities or self-regulatory bodies as may be necessary or reasonably advisable in light of the business and operations of the Company to enable the
Shareholders to consummate the disposition of such Registrable Securities in accordance with the intended method or methods of disposition thereof; 

(f) immediately notify the Shareholders and any underwriter(s), at any time when a prospectus relating thereto is required to be delivered
under the 1933 Act, of the occurrence of any event which will have the result that, the prospectus contains an untrue statement of a material fact or omits to state any fact necessary to make the statements therein not misleading in the light of the
circumstances under which they were made; 
 (g) notify the Shareholders (i) when the prospectus or any prospectus supplement or
post-effective amendment has been filed and, with respect to such Registration Statement or any post-effective amendment, when the same has become effective, (ii) of any request by the SEC for amendments or supplements to such registration
statement or to amend or to supplement such prospectus or for additional information and (iii) of the issuance by the SEC of any stop order suspending the effectiveness of such registration statement or the initiation of any proceedings for any
of such purposes; 
 (h) use its commercially reasonable efforts to cause all such Registrable Securities to be listed on each securities
exchange on which Common Shares are then listed; 
 (i) provide a transfer agent and registrar for all such Registrable Securities not later
than the effective date of such Registration Statement; 
 (j) enter into such customary agreements (including underwriting agreements with
customary provisions) and take all such other actions as the Shareholders or the underwriters, if any, reasonably request in order to expedite or facilitate the disposition of such Registrable Securities; 

(k) otherwise use its commercially reasonable efforts to comply with all applicable rules and regulations of the SEC, and make available to its
security holders, as soon as reasonably practicable, an earnings statement covering the period of at least twelve months beginning with the first day of the Company’s first full calendar quarter after the effective date of the Registration
Statement, which earnings statement will satisfy the provisions of Section 10(a) of the 1933 Act and Rule 158 thereunder; 
 (l) make
available for inspection by the Shareholders, any underwriter participating in any disposition pursuant to such Registration Statement and any attorney, accountant or other agent retained by a Shareholder or underwriter, all financial and other
records, pertinent corporate documents and documents relating to the business of the Company, and cause the Company’s officers, directors, employees and independent accountants to supply all information reasonably requested by a Shareholder or
any such underwriter, attorney, accountant or agent in connection with such Registration Statement; provided, that such Shareholder will, and will use its commercially reasonable efforts to cause each such underwriter, accountant or other agent to
enter into a customary confidentiality agreement in form and substance reasonably satisfactory to the Company; provided further, that such confidentiality agreement will not contain terms that would prohibit any such Person from complying with its
obligations under applicable law or Nasdaq rules; 

  
 - 5 - 

 (m) in the event of the issuance of any stop order suspending the effectiveness of a Registration
Statement, or of any order suspending or preventing the use of any related prospectus or ceasing trading of any securities included in such Registration Statement for sale in any jurisdiction, use its commercially reasonable efforts promptly to
obtain the withdrawal of such order; 
 (n) enter into such agreements and take such other actions as the Shareholders or the underwriters
reasonably request in order to expedite or facilitate the disposition of such Registrable Securities, including, without limitation, preparing for and participating in such number of “road shows” and all such other customary selling
efforts as the underwriters reasonably request in order to expedite or facilitate such disposition; 
 (o) if such registration relates to an
underwritten offering, obtain a comfort letter, addressed to the Shareholders (and, if such registration includes an underwritten public offering to the underwriters of such offering), signed by the Company’s independent public accountants in
customary form and covering such matters of the type customarily covered by comfort letters; 
 (p) if such registration relates to an
underwritten offering, provide a legal opinion of the Company’s outside counsel, addressed to the underwriters of any underwritten public offering, with respect to the Registration Statement and prospectus in customary form and covering such
matters of the type customarily covered by legal opinions of such nature; 
 (q) if such registration relates to an underwritten offering,
furnish to the Shareholders such information and assistance as the Shareholders may reasonably request in connection with any “due diligence” effort which the Shareholders deem appropriate; and 

(r) use its commercially reasonable efforts to take or cause to be taken all other actions, and do and cause to be done all other things,
necessary or reasonably advisable to effect the registration of such Registrable Securities contemplated hereby. 
 The Company agrees not
to file or make any amendment to any Registration Statement with respect to any Registrable Securities, or any amendment of or supplement to the prospectus used in connection therewith, that refers to the Shareholders by name, or otherwise
identifies the Shareholders as the holders of any securities of the Company, without the consent of each such Shareholder, such consent not to be unreasonably withheld or delayed; unless such disclosure is required by law. 

The Company may require the Shareholders to furnish the Company with such information regarding the Shareholders and pertinent to the
disclosure requirements relating to the registration and the distribution of such securities as the Company may from time to time reasonably request in writing.

 4. Registration Expenses. 

(a) Except as otherwise provided for herein, all expenses incidental to the Company’s performance of or compliance with this Agreement,
including, without limitation, all registration and filing fees (including SEC registration and National Association of Securities Dealers filing fees), fees and expenses of compliance with securities or blue sky laws, word processing, duplicating
and printing expenses, messenger and delivery expenses, transfer agent’s and registrar’s fees, cost of distributing prospectuses in preliminary and final form, as well as any supplements thereto, and fees and disbursements of
counsel for the Company and all independent certified public accountants, underwriters and other Persons retained by the Company (all such expenses, “Registration Expenses”), will be borne by the Company. In addition, the Company
will, in any event, pay its internal expenses (including, without limitation, all salaries and expenses of its officers and employees performing legal or accounting duties), the expenses of any annual audit or quarterly review, the expenses of any
liability insurance and the expenses and fees for listing the securities to be registered on each securities exchange or automatic quotation system on which similar securities issued by the Company are then listed (including Nasdaq). Notwithstanding
the foregoing, all Selling Expenses will be borne by the holders of the securities so registered pro rata on the basis of the number of their shares so registered. 

(b) In connection with the Mandatory Shelf Registration Statement and each Piggyback Registration, the Company will reimburse the Shareholders
for reasonable fees and disbursements, in an amount not to exceed $25,000, of one law firm, chosen by the Vatera Shareholder. 
 5.
Indemnification. 
 (a) The Company agrees to indemnify and hold harmless, and hereby does indemnify and hold harmless, each Shareholder, its
affiliates and their respective officers, directors and partners and each Person who controls each Shareholder (within the meaning of the 1933 Act) against, and pay and reimburse such holder, affiliate, director, officer or partner or controlling
person for any losses, claims, damages, expenses, liabilities, joint or several, to which such holder or any such affiliate, director, officer or partner or controlling person may become subject under the 1933 Act or otherwise, insofar as such
losses, claims, damages or liabilities (or actions or proceedings, whether commenced or threatened, in respect thereof) arise out of or are based upon (i) any untrue or alleged untrue statement of material fact contained in any Registration
Statement, prospectus or preliminary prospectus or any amendment thereof or supplement thereto, or any “issuer free writing prospectus” (as defined in 1933 Act Rule 433), (ii) any omission or alleged omission of a material fact required to
be stated therein or necessary to make the statements therein not misleading, (iii) any violation or alleged violation by the Company of any rule or regulation promulgated under the 1933 Act, the 1934 Act, the National Association of Securities
Dealers or any state securities laws applicable to the Company and relating to action or inaction required of the Company in connection with any such registration, and the Company will pay and reimburse each Shareholder and each such affiliate,
director, officer, partner and controlling person for the legal fees and expenses of one counsel, and any other nonlegal expenses, actually and reasonably incurred by them in connection with investigating, defending or settling any such loss, claim,
liability, action or proceeding or (iv) the failure to include, at the time of pricing any offering, the information required by Sections 12(a)(2) and 17(a)(2) of the 1933 Act; provided, that the Company will not be liable in any such case to
the extent that any such loss, claim, damage, expense, liability (or action or proceeding in respect 

  
 - 7 - 

 
thereof) or expense arises out of or is based upon an untrue statement or alleged untrue statement, or omission or alleged omission, made in such Registration Statement, any such prospectus or
preliminary prospectus or any amendment or supplement thereto, or in any application, in reliance upon, and in conformity with, written information prepared and furnished to the Company by a Shareholder expressly for use therein or by such
Shareholder’s failure to deliver, to the extent required by law and except to the extent such failure results from a failure by the Company to comply with Section 3(f), a copy of the Registration Statement or prospectus or any amendments
or supplements thereto after the Company has furnished the Shareholders with a sufficient number of copies of the same. In connection with an underwritten offering, the Company, if requested, will indemnify such underwriters, their officers and
directors and each Person who controls such underwriters (within the meaning of the 1933 Act) to at least the same extent as provided above with respect to the indemnification of the Shareholders. 

(b) In connection with any Registration Statement in which any Shareholder is participating, such Shareholder will furnish to the Company in
writing such information as the Company reasonably requests for use in connection with any such Registration Statement or prospectus and will indemnify and hold harmless the Company, its directors and officers, each other Person who controls the
Company (within the meaning of the 1933 Act) and each underwriter (to the extent required by such underwriter) against any losses, claims, damages, expenses, liabilities (or actions or proceedings, whether commenced or threatened, in respect
thereof), joint or several, to which the Company or any such director or officer, any such underwriter or controlling person may become subject under the 1933 Act or otherwise, insofar as such losses, claims, damages, liabilities, actions or
proceedings arise out of or are based upon (i) any untrue or alleged untrue statement of material fact contained in the Registration Statement, prospectus or preliminary prospectus or any amendment thereof or supplement thereto or in any
application or (ii) any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, but only to the extent that such untrue statement or omission is made in such
Registration Statement, any such prospectus or preliminary prospectus or any amendment or supplement thereto, or in any application, in reliance upon and in conformity with written information prepared and furnished to the Company by such
Shareholder expressly for use therein, and such Shareholder will reimburse the Company and each such director, officer, underwriter and controlling Person for any legal or any other expenses actually and reasonably incurred by them in connection
with investigating, defending or settling any such loss, claim, liability, action or proceeding; provided, that the obligation to indemnify and hold harmless will be individual and several to such Shareholder and will be limited to the amount of net
proceeds received by such Shareholder from the sale of Registrable Securities pursuant to such Registration Statement. 
 (c) Any Person
entitled to indemnification hereunder will (i) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification and (ii) unless in such indemnified party’s reasonable judgment a conflict
of interest between such indemnified and indemnifying parties may exist with respect to such claim, permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party. If such defense is
assumed, the indemnifying party will not be subject to any liability for any settlement made by the indemnified party without its prior written consent (but such consent will not be unreasonably withheld). An indemnifying party who is not entitled
to, or elects not to, assume the defense of a claim will not be obligated to pay the fees and 

  
 - 8 - 

 
expenses of more than one counsel for all parties indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of any indemnified party a conflict of
interest may exist between such indemnified party and any other of such indemnified parties with respect to such claim. Failure to give prompt written notice shall not release the indemnifying party from its obligations hereunder except to the
extent that such indemnifying party is materially prejudiced as a result of such failure to give notice. 
 (d) The indemnification provided
for under this Agreement will remain in full force and effect regardless of any investigation made by or on behalf of the indemnified party or any officer, director or controlling Person of such indemnified party and will survive the registration
and sale of any securities by any Person entitled to any indemnification hereunder and the expiration or termination of this Agreement. 

(e) If the indemnification provided for in this Section 5 is held by a court of competent jurisdiction to be unavailable to an indemnified
party with respect to any loss, liability, claim, damage or expense referred to herein, then the indemnifying party, in lieu of indemnifying such indemnified party hereunder, will contribute to the amount paid or payable by such indemnified party as
a result of such loss, liability, claim, damage or expense in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and of the indemnified party on the other hand in connection with the statements
or omissions which resulted in such loss, liability, claim, damage or expense as well as any other relevant equitable considerations. The relevant fault of the indemnifying party and the indemnified party will be determined by reference to, among
other things, whether the untrue or alleged untrue statement of a material fact or the omission to state a material fact relates to information supplied by the indemnifying party or by the indemnified party and the parties’ relative intent,
knowledge, access to information and opportunity to correct or prevent such statement or omission. Notwithstanding the foregoing, the amount a Shareholder will be obligated to contribute pursuant to this Section 5(e) will be limited to an
amount equal to the net proceeds to such Shareholder of the Registrable Securities sold pursuant to the registration statement which gives rise to such obligation to contribute (less the aggregate amount of any damages which such Shareholder has
otherwise been required to pay in respect of such loss, claim, damage, expense, liability or action or any substantially similar loss, claim, damage, expense, liability or action arising from the sale of such Registrable Securities). 

6. Participation in Underwritten Registrations. 

(a) No Shareholder may participate in any registration hereunder that is underwritten unless it (i) agrees to sell its Registrable
Securities on the basis provided in any underwriting arrangements approved by the Person or Persons entitled hereunder to approve such arrangements (including, without limitation, pursuant to the terms of any over-allotment or “green shoe”
option requested by the managing underwriter(s); provided, that a Shareholder will not be required to sell more than the number of Registrable Securities that it has requested the Company to include in any registration), (ii) completes and executes
all questionnaires, powers of attorney, indemnities, underwriting agreements and other documents reasonably required under the terms of such underwriting arrangements, and (iii) cooperates with the Company’s reasonable requests in
connection with such registration or qualification (it being understood that the Company’s failure to perform its obligations hereunder, which failure is caused by such 

  
 - 9 - 

 
Shareholder’s failure to cooperate, will not constitute a breach by the Company of this Agreement). Notwithstanding the foregoing, a Shareholder will not be required to agree to any
indemnification obligations on the part of such Shareholder that are materially greater than its obligations pursuant to Section 6(b). 

(b) Each Shareholder agrees that, if it is participating in any registration hereunder, upon receipt of any notice from the Company of the
happening of any event of the kind described in subsection 3(f) above, such Shareholder will forthwith discontinue the disposition of its Registrable Securities pursuant to the Registration Statement until it receives copies of a supplemented or
amended prospectus as contemplated by such Section 3(f). In the event the Company gives any such notice, the applicable time period during which a Registration Statement is to remain effective will be extended by the number of days during the
period from and including the date of the giving of such notice pursuant to this Section 6(b) to and including the date when such Shareholder will have received the copies of the supplemented or amended prospectus contemplated by
Section 3(f). 
 7. Rule 144; Legend Removal. 

(a) Facilitation of Sales Pursuant to Rule 144. The Company covenants to the Shareholders that to the extent it shall be required to do
so under the 1934 Act, the Company shall use its commercially reasonable efforts to (i) timely file the reports required to be filed by it under the 1934 Act or the 1933 Act (including the reports under Sections 13 and 15(d) of the 1934 Act
referred to in subparagraph (c)(1) of Rule 144), and (ii) make and keep public information available as those terms are understood and defined in Rule 144 under the 1933 Act, all to the extent required from time to time to enable the
Shareholders to sell Registrable Securities without registration under the Securities Act within the limitations of the exemption provided by Rule 144. Upon the request of any Shareholder in connection with its sale pursuant to Rule 144, the Company
shall deliver to such Shareholder a written statement as to whether it has complied with such requirements. 
 (b) Availability of Rule
144 Not Excuse for Obligations. The fact that any Shareholder may become eligible to sell its Registrable Securities pursuant to Rule 144 shall not (i) cause such Securities to cease to be Registrable Securities or (ii) excuse the
Company’s obligations set forth in this Agreement. 
 (c) Upon request of any Shareholder, upon receipt by the Company of an opinion of
counsel reasonably satisfactory to the Company to the effect that such legend is no longer required under the 1933 Act and applicable state laws, the Company shall promptly cause any legend affixed to any Registrable Securities to be removed from
any certificate for any Registrable Securities, including by providing any opinion of counsel to the Company that may be reasonably required by the transfer agent to effect such removal. 

8. Term. This Agreement will be effective as of the date hereof and will continue in effect thereafter until the earliest of
(a) its termination by the consent of the Vatera Shareholder or its successor(s) in interest, (b) the date on which the Vatera Shareholder or its successor(s) in interest holds a number of shares of Company Common Stock equal to or less
than 10% of the total number of shares of Company Common Stock issued and outstanding (on a non-fully diluted basis) and (c) the dissolution, liquidation or winding up of the Company.
