 Exhibit A 
 CONFIDENTIALITY, NON-COMPETITION 
 AND INVENTION ASSIGNMENT
AGREEMENT 
 As a condition of and in consideration of my employment by Tengion, Inc., a Delaware corporation (the
“Company”), I agree to the following terms of this Confidentiality, Non-Competition and Invention Assignment Agreement (the “Agreement”): 
 1. Confidential Information. 
 (a) Company Information. I acknowledge that, during
the course of my employment, I will have access to information about the Company and that my employment with the Company shall bring me into close contact with confidential and proprietary information of the Company. In recognition of the foregoing,
I agree, at all times during the term of my employment with the Company and thereafter, to hold in strict confidence, and not to use, except for the benefit of the Company, or to disclose to any person, firm, corporation or other entity without
written authorization of the Company, any Confidential Information of the Company (as defined below) which I encounter, obtain, create or develop. I further agree not to make copies of such Confidential Information except as authorized by the
Company. 
 (b) Confidential Information Defined. I understand that “Confidential Information” means any Company
proprietary information, technical, business and financial data, trade secrets or know-how, including, but not limited to, research, product plans, products, services, vendor lists, supplier lists and suppliers, customer lists and customers
(including, but not limited to, customers of the Company on whom I call or with whom I become acquainted during the term of my employment), contacts at or knowledge of clients or prospective clients of the Company, pricing information and costs,
markets, software, ideas, concepts, developments, inventions (including Inventions, as defined in Section 2(b)), discoveries, protocols, scripts, features and modes of operation, interfaces, works of authorship, databases or database criteria,
algorithms, methodologies, processes, formulas, computer codes, technology, designs, drawings, internal documentation, engineering materials, hardware configuration information, marketing data, licenses, finances, budgets, projections, forecasts,
strategies, salaries, terms of compensation of other employees or other business information disclosed to me by the Company either directly or indirectly in writing, orally or by drawings or observation during the period of my employment with the
Company (the “Employment Period”) and any other materials of any nature relating to any matter within the scope of the business of the Company or concerning any of the dealings or affairs of the Company. 
 (c) Limits on Scope of Confidential Information. 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 is confidential or proprietary information of the Company or its customers or suppliers, whether of a
technical nature or otherwise. Notwithstanding the foregoing, I understand that Confidential Information shall not include (i) any of the foregoing items which have become publicly known through no wrongful act of mine or of others who were
under confidentiality obligations as to the item or items involved; or (ii) any information that I am required to disclose to, or by, any governmental or judicial authority; provided, however, that I give the Company prompt written notice
thereof so that the Company may seek an appropriate protective order and/or waive in writing compliance with the confidentiality provisions of this Agreement. 
 (d) Former Employer Information. 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 to keep in confidence
proprietary information, knowledge or data acquired by me in confidence or trust prior or subsequent to the commencement of my employment with the Company, and I will not disclose to the Company, or induce the Company to use, any inventions,
confidential or proprietary information or material

 
I may have obtained in connection with employment with any prior employer in violation of a confidentiality agreement, nondisclosure agreement or similar agreement with such prior employer.

 (e) 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 onto use it except as necessary in carrying out my work for the Company consistent with the Company’s agreement with any such third party.

 2. Inventions. 
 (a) Inventions Retained and Licensed. I have attached hereto, as Exhibit A, a list describing with particularity all intellectual property, including, but not limited to, property inventions, copyrights,
copyright applications or registrations, original works of authorship, developments, improvements, patents, patent applications, trademarks, trademark applications, trade names or trade secrets which were created or owned by me prior to the
commencement of my employment and 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 (collectively referred to as “Prior
Inventions”), 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 Employment Period, I agree to incorporate into a Company product,
process or machine a Prior Invention owned by me or in which I have an interest, absent a prior written agreement or license between myself and the Company for such incorporation of the Prior Invention into a Company product, process or machine,
then 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, without additional compensation, 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, whether or not during regular working hours, during the Employment Period, and with respect to Inventions in the field of tissue
engineering and organ regeneration (the “Field of Interest”), for a period of one (1) year thereafter, provided they either (i) relate at the time of conception or development to the actual or demonstrably proposed business or
research and development activities of the Company; (ii) result from or relate to any work performed for the Company; or (iii) are developed through the use of Confidential Information and/or Company owned resources or in consultation with
Company personnel (collectively referred to as “Inventions”). I further acknowledge that all Inventions which are made by me (solely or jointly with others) within the scope of and during the Employment Period are “works made for
hire” (to the greatest extent permitted by applicable law) for which I am, in part, compensated by my salary, unless regulated otherwise by law but that, in the event any such Invention is deemed not to be a work made for hire, I hereby assign
all rights in such Invention to the Company. I further represent and agree that to the best of my knowledge and belief, the practice by the Company of any of the Inventions will not violate or infringe upon any right, patent, copyright, trademark or
right of privacy, or constitute libel or slander against or violate any other rights of any person, firm or corporation, and that I will use my best efforts to prevent any such violation. 
 (c) Maintenance of Records. I agree to keep and maintain reasonable and current written records of all Inventions made by me (solely or
jointly with others) during the Employment Period. 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 discretion of the Company
for the purpose of furthering the Company’s business. 
 (d) Intellectual Property Rights. I agree to assist the Company,
or its designee, at the Company’s expense, in every reasonable way to secure the Company’s rights in the Inventions and any copyrights, copyright applications or registrations, patents, patent applications, trademarks, trademark
applications, trade names, service marks, logos, database rights, algorithms, know-how, domain names, mask work rights, moral rights, or other intellectual property rights relating thereto in any and all countries, including the disclosure to the
Company 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 shall deem necessary in order to apply for, obtain,
maintain and transfer such rights and in order to assign and convey to the Company, its successors, assigns and nominees the sole and exclusive right, title and interest in and to such Inventions, and any intellectual property or other proprietary
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 is unable because of my mental or physical incapacity or unavailability for any other reason to secure my signature to apply for or to pursue any application for
any United States or foreign patents or copyright registrations covering Inventions or original works of authorship assigned to the Company 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 or records and to do all other lawfully permitted acts to further the application for, prosecution, issuance, maintenance or
transfer of letters patent or registrations thereon with the same legal force and effect as if originally executed by me. I hereby waive and irrevocably quitclaim to the Company any and all claims, of any nature whatsoever, which I now or hereafter
have for past, present or future infringement of any and all proprietary rights assigned to the Company. 
 3. Returning Company
Documents. I agree that, at the time of termination of my employment with the Company for any reason, I will deliver to the Company (and will not keep in my possession, recreate or deliver to anyone else) any and all Confidential Information and all
other documents, materials, information or property developed by me pursuant to my employment or otherwise belonging to the Company, its successors or assigns. 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. In the event of the termination of my employment, I agree to sign and
deliver the “Termination Certification” attached hereto as Exhibit B. 
 4. Disclosure of Agreement. During the
Restricted Period (as defined below), I will disclose the existence of this Agreement to any prospective employer, partner, co-venturer, investor or lender prior to entering into an employment, partnership or other business relationship with such
person or entity; provided, however, the foregoing shall not obligate me to disclose the existence of this Agreement when I am engaging in activities unrelated to the business of the Company. 
 5. Solicitation of Employees and Clients. I recognize and acknowledge that during my employment with the Company, I will have access to,
learn, be provided with and, in some cases, prepare and create certain Confidential Information, all of which is of substantial value to the Company’s business. I further recognize that I will have substantial contacts with customers, clients,
investors, consultants, contractors and strategic partners of the Company and hereby acknowledge a fiduciary relationship will exist between me and the Company by reason of my having received and been privy to client, customer and other

 
proprietary information which would give me an unfair advantage in attracting the Company’s clients and customers or otherwise competing against the Company. In light of the foregoing,
during the Employment Period and for a period of twenty four (24) months after the date of the termination of my employment for any reason (the “Restricted Period”), I shall not, without the prior written consent of the Company,
directly or indirectly, either individually or on behalf of or through any other person, business, enterprise or entity (other than the Company), (i) solicit or induce, or in any manner attempt to solicit or induce, any person employed by, an
agent of, or a service provider to, the Company to terminate such person’s employment, agency or service, as the case may be, with the Company; or (ii) divert, or attempt to divert, any person, concern, or entity from doing business with
the Company, or attempt to induce any such person, concern or entity to cease being a customer or supplier of the Company. 
 6.
Non-Competition. 
 I agree that, during the term of my relationship with the Company (whether as an employee, consultant or
otherwise), and for a period of twelve (12) months immediately following the termination of my relationship with the Company for any reason, with or without cause (the “Non-Compete Period”), I will not, without the prior written
consent of the Company, for myself or on behalf of any other person or entity, directly or indirectly, either as principal, agent, employee, consultant, representative or in any other capacity, own, manage, operate or control, or be connected or
employed by, or otherwise associate in any manner with, or engage in any business which is in the Field of Interest within the United States. 
 7. Reasonableness of Restrictions. I recognize and acknowledge that the restrictions and limitations set forth in this Agreement, including such provisions set forth in Sections 5 and 6 above, are
legitimate and fair in light of my access to Confidential Information, my substantial contacts with clients of the Company and the Company’s need to develop, market and sell its services and/or products. I further acknowledge that the
restrictions and limitations set forth in this Agreement will in no way interfere with my ability to earn a living following the termination of my employment with the Company and that my ability to earn a livelihood without violating such
restrictions is a material condition to my employment with the Company. 
 8. Independence. Each of the rights enumerated above
shall be independent of the others and shall be in addition to and not in lieu of any other rights and remedies available to the Company at law or in equity. 
 9. Severability. If any provision/s and/or covenant/s contained herein or any part of any of them is hereafter construed or adjudicated to be invalid or unenforceable, the same shall not affect the
remainder of the provision/s and/or covenant/s or rights or remedies, which shall be given full effect without regard to the invalid or unenforceable portions. Additionally, in the event any provision/s and/or covenant/s contained herein are held to
be invalid or unenforceable because of the duration, area, scope, activity and/or subject contemplated under such provision/s and/or covenant/s, I agree that the court making such determination shall have the power to reduce the applicable duration,
area, scope, activity and/or subject to the maximum and/or broadest extent permissible by law and that, in its reduced form, said provision/s and/or covenant/s shall then be enforceable. I further acknowledge that in the event any provision/s and/or
covenant/s contained herein or any part of any of them is hereafter construed or adjudicated to be invalid or unenforceable in any particular jurisdiction, then, any such invalidity or unenforceability shall not invalidate or render unenforceable
such provision and/or covenant in any other jurisdiction. 
 10. Injunctive Relief. I expressly acknowledge that any breach or
threatened breach of any of the terms and/or conditions set forth in this Agreement may result in substantial, continuing and irreparable injury to the Company. Therefore, I hereby agree that, in addition to any other remedy that may be available to
the Company, the Company may be entitled to injunctive relief, specific performance or other equitable relief by a court of appropriate jurisdiction in the event of any breach or threatened breach of the terms of this

 
Agreement. Notwithstanding any other provision to the contrary, I acknowledge and agree that the Restricted Period or the Non-Compete Period, as applicable, shall be tolled during any period of
violation of any of the covenants in Section 5 or Section 6 hereof and during any other period required for litigation during which the Company seeks to enforce such covenants against me if it is ultimately determined that I was in breach
of such covenants. 
 11. General Provisions. 
 (a) Governing Law and Forum Selection. The validity, interpretation, construction and performance of this Agreement shall be governed by the laws of the United States of America and the Commonwealth of
Pennsylvania, without giving effect to the principles of conflict of laws. I agree that any disputes that may arise from this Agreement shall be resolved in State or Federal courts located in the Commonwealth of Pennsylvania, exclusively, and
consent to the jurisdiction of such courts. 
 (b) Notices. All notices or other communications given hereunder shall be in
writing and shall be deemed effective upon delivery at the address of the party to be notified and shall be mailed by certified or registered mail, return receipt requested, delivered by courier, telecopied, or sent by other facsimile method

such Inventions, and any intellectual property or other proprietary 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 is unable because of my mental or physical incapacity or unavailability for any other reason to
secure my signature to apply for or to pursue any application for any United States or foreign patents or copyright registrations covering Inventions or original works of authorship assigned to the Company 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 or records and to do all other lawfully permitted acts to
further the application for, prosecution, issuance, maintenance or transfer of letters patent or registrations thereon with the same legal force and effect as if originally executed by me. I hereby waive and irrevocably quitclaim to the Company any
and all claims, of any nature whatsoever, which I now or hereafter have for past, present or future infringement of any and all proprietary rights assigned to the Company. 
 3. Returning Company Documents. I agree that, at the time of termination of my employment with the Company for any reason, I
will deliver to the Company (and will not keep in my possession, recreate or deliver to anyone else) any and all Confidential Information and all other documents, materials, information or property developed by me pursuant to my employment or
otherwise belonging to the Company, its successors or assigns. 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. In the event of the termination of my employment, I agree to sign and deliver the “Termination Certification” attached hereto as Exhibit B. 
 4. Disclosure of Agreement. During the Restricted Period (as defined below), I will disclose the existence of this Agreement
to any prospective employer, partner, co-venturer, investor or lender prior to entering into an employment, partnership or other business relationship with such person or entity; provided, however, the foregoing shall not obligate me
to disclose the existence of this Agreement when I am engaging in activities unrelated to the business of the Company. 
 5.
Solicitation of Employees and Customers. I recognize and acknowledge that during my employment with the Company, I will have access to, learn, be provided with and, in some cases, prepare and create certain Confidential Information, all
of which is of substantial value to the Company’s business. I further recognize that I will have substantial contacts with customers, clients, investors, consultants,

 
contractors and strategic partners of the Company and hereby acknowledge a fiduciary relationship will exist between me and the Company by reason of my having received and been privy to client,
customer and other proprietary information which would give me an unfair advantage in attracting the Company’s clients and customers or otherwise competing against the Company. In light of the foregoing, during the Employment Period and for a
period of twenty four (24) months after the date of the termination of my employment for any reason (the “Restricted Period”), I shall not, without the prior written consent of the Company, directly or indirectly, either
individually or on behalf of or through any other person, business, enterprise or entity (other than the Company), (i) solicit or induce, or in any manner attempt to solicit or induce, any person employed by, an agent of, or a service provider
to, the Company to terminate such person’s employment, agency or service, as the case may be, with the Company; or (ii) divert, or attempt to divert, any person, concern, or entity from doing business with the Company, or attempt to induce
any such person, concern or entity to cease being a customer or supplier of the Company. 
 6. Non-Competition. I
agree that, during the term of my relationship with the Company (whether as an employee, consultant or otherwise), and for a period of twelve (12) months immediately following the termination of my relationship with the Company for any reason,
with or without cause (the “Non-Compete Period”), I will not, without the prior written consent of the Company, for myself or on behalf of any other person or entity, directly or indirectly, either as principal, agent, employee,
consultant, representative or in any other capacity, own, manage, operate or control, or be connected or employed by, or otherwise associate in any manner with, or engage in, any business located anywhere in the world that is in the field of tissue
engineering and organ regeneration and is developing a product or products (in any stage, whether preliminary or final) that competes or will compete, directly or indirectly, with the product or products (in any stage of development, whether
preliminary or final) of the Company as contemplated during the term of my employment (the “Field of Interest”). 
 7. Reasonableness of Restrictions. I recognize and acknowledge that the restrictions and limitations set forth in this Agreement, including such provisions set forth in Sections 5 and 6 above, are legitimate and
fair in light of my access to Confidential Information, my substantial contacts with customers of the Company and the Company’s need to develop, market and sell its services and/or products. I further acknowledge that the restrictions and
limitations set forth in this Agreement will in no way interfere with my ability to. earn a living following the termination of my employment with the Company and that my ability to earn a livelihood without violating such restrictions is a material
condition to my employment with the Company. 
 8. Independence. Each of the rights enumerated above shall be
independent of the others and shall be in addition to and not in lieu of any other rights and remedies available to the Company at law or in equity. 
 9. Severability and Judicial Modification. If any provision or covenant (or both) contained herein or any part of any of them is hereafter construed or adjudicated to be invalid or
unenforceable, the same shall not affect the remainder of the provisions or covenants (or both) or rights or remedies (or both), which shall be given full effect without regard to the invalid or unenforceable portions. Additionally, in the event any
provision or covenant (or both) contained herein is held to be invalid or unenforceable because of the duration, area, scope, activity and/or subject contemplated under such provision or covenant (or both), I agree that the court making such
determination shall have the power to reduce the applicable duration, area, scope, activity or subject (or any combination of any of the foregoing) to the maximum or broadest extent permissible by law and that, in its reduced form, the provision or
covenant (or both) in question shall then be enforceable. I further acknowledge that in the event any provision or covenant (or both) contained herein or any part of any of them is hereafter construed or adjudicated to be invalid or unenforceable in
any particular jurisdiction, then, any such invalidity or unenforceability shall not invalidate or render unenforceable such provision and/or covenant in any other jurisdiction. 

 10. Injunctive Relief. I expressly acknowledge that any breach or threatened
breach of any of the terms and/or conditions set forth in this Agreement may result in substantial, continuing and irreparable injury to the Company. Therefore, I hereby agree that, in addition to any other remedy that may be available to the
Company, the Company may be entitled to injunctive relief, specific performance or other equitable relief by a court of appropriate jurisdiction in the event of any breach or threatened breach of the terms of this Agreement. Notwithstanding any
other provision to the contrary, I acknowledge and agree that the Restricted Period or the Non-Compete Period, as applicable, shall be tolled during any period of violation of any of the covenants in Section 5 or Section 6
hereof and during any other period required for litigation during which the Company seeks to enforce such covenants against me if it is ultimately determined that I was in breach of such covenants. 
 11. General Provisions. 
 (a) Governing Law and Forum Selection. The validity, interpretation, construction and performance of this Agreement shall be governed by the laws of the United States of America and the
Commonwealth of Pennsylvania, without giving effect to the principles of conflict of laws. I agree that any disputes that may arise from this Agreement shall be resolved in State or Federal courts located in the Commonwealth of Pennsylvania,
exclusively, and consent to the jurisdiction of such courts.

	RE:	Acceptance of Employment 

 DATE:
September 22, 2004 
 I represent that to the best of my understanding, I am under no common law or contractual obligation
that would be an impediment to my employment with Tengion, Inc. (the “Company”). I will not use or disclose any confidential, proprietary or trade secret information belonging to any former employer, in my employment with the Company.

 I represent and warrant that I have not retained or copied any confidential, proprietary or trade secret information or
property, in any form, belonging to any former employer, and that if I was in possession of any such information or property, I have returned it to my former employer(s). 
 I agree that, if at any time during my employment with the Company, I am at risk of using or disclosing any confidential, proprietary or trade secret information belonging to any former employer, I will
immediately recuse myself from acting on the matter and advise the Chief Financial Officer of the Company, without revealing any protected information, the nature of my conflict; provided, however, that 1 will not be required to recuse myself in the
event such disclosure is required by law or regulation or as a result of a response to a valid order of a court or another governmental body of the United States or any political subdivision thereof. 
 I understand that if any of the representations or warranties herein are intentionally false, or if I violate any of the terms of this
memorandum, I will forfeit any unvested stock incentives awarded or issued to me.

 Dear Mark:

 Based in part on our recent discussions and reference checks, my colleagues and I believe you can make a meaningful contribution to our
Company. As a result, I am pleased to formally extend this offer for you to join Tengion, Inc. (the “Company” or “we”). 
 Our mission and goals are extremely exciting and potentially of profound value to society. In order to ensure we fulfill our mission and achieve our goals ,we have, from our inception, takes pains to
recruit exceptionally talented individuals who are committed to teamwork and excellence, who perceive the excitement of our visions and who share our ethical values. We hope you will be as elated with the prospect of your joining us as we are.

	 	1.	Your position is Vice President, Marketing and Commercial Planning. You will report directly to the chief executive officer.

(20%) of your base salary. The magnitude of the bonus, if any, will be determined by the Company’s Board of Directors (the “Board”) and your manager in their sole discretion, based upon a combination of the Company’s

 In addition to the foregoing, upon acceptance of this offer, you will become eligible for a bonus in the amount of twenty-five thousand
dollars ($25,000), which will become payable upon the actual commencement of your employment. You will receive as additional bonus payment of twelve thousand five hundred dollars ($12,500) on the six (6) month anniversary of the Commencement

Transaction (and not the result of your job performance in whole or in part), all of the shares underlying the Option shall vest in full (if not sooner vested). 
  

	 	5.	You will be eligible to enroll in our group benefits program on the first day of the month following your date of hire, in accordance with the terms and requirements of
Tengion’s group health plan (since your Commencement Date is the first day of the month, you will become eligible to enroll in our group benefits program as of that date). We offer a medical plan through our healthcare provider, United

increases, merit bonuses and stock incentive grants are entirely discretionary and not guaranteed.

to the Company of

  

 CONFIDENTIALITY, NON-COMPETITION AND INVENTION ASSIGNMENT AGREEMENT

all pertinent information and data with respect thereto, the execution of all applications specifications, oaths, assignments, recordations, and all other instruments which the Company shall deem
necessary in order to apply for, obtain, maintain, perfect and/or transfer such rights and in order to assign and convey to the Company, its successors, assigns and nominees the sole and exclusive right, title and interest in and to such Inventions,
and any intellectual property or other proprietary 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 is unable because of my mental or physical incapacity or unavailability for any other reason to secure my
signature to apply for or to pursue any application for any Untied States or foreign patents or copyright registrations covering inventions or original works of authorship assigned to the Company 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 or records and to do all other lawfully permitted acts to further the
application for, prosecution, issuance, maintenance or transfer of letters patent or registrations thereon with the same legal force and effect as if originally executed by me. I hereby waive and irrevocably quitclaim to the Company any and all
claims, of any nature whatsoever, which I now or hereafter have for past, present or future infringement of any and all propriety rights assigned by the Company. 
 3. Returning Company Documents. I agree that, at the time of termination of my employment with the Company for any reason, I will deliver to the Company (and will not keep in my possession,
recreate or deliver to anyone else) any and all Confidential Information and all other documents, materials, information or property developed by me pursuant to my employment or otherwise belonging to the Company, its successor or assigns. 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.
In the event of the termination of my employment, I agree to sign and deliver the “Termination Certification” attached hereto as Exhibit B. 
 4. Disclosure of Agreement. During the Restricted Period (as defined below), I will disclose the existence of this Agreement to any prospective employer, partner, co-venturer, investor or lender
prior to entering into an employment, partnership or other business relationship with such person or entity; provided, however, the foregoing shall not obligate me to disclose the existence of this Agreement when I am engaging in
activities unrelated to the business of the Company. 
 5. Solicitation of Employees and Customers. I recognize and
acknowledge that during my employment with the Company, I will have access to, learn, be provided with and, in some cases, prepare and create certain Confidential Information, all of which is of substantial value to the Company’s business. I
further recognize that I will have substantial contacts and good will with customers, clients, investors, consultants, contractors and strategic partners of the Company and hereby acknowledge a fiduciary relationship will exist between me and the
Company by reason of my having received, been privy to and possessed client, customer and other proprietary information and good will which would give me an unfair advantage in attaining the Company’s clients and customers or otherwise
competing against the Company. In light of the foregoing, during the Employment Period and for a period of twenty-four (24) months after the date of the termination of my employment for any reason (the “Registered Period”), I
shall not, without the prior written consent of the Company, directly or indirectly, either individually or on behalf of or through any other person, business, enterprise or entity (other than the Company), (i) solicit or induce, or in any
manner attempt to solicit or induce, or in any manner assist others to solicit or induce, any person employed by, an agent of, or a service provider to, the Company to terminate such person’s employment, agency or service, as the case may be,
with the Company; or (ii) divert, or attempt to divert, or in any manner assist others to divert or attempt to divert, any person, concern, or entity form doing business with the Company, or attempt to induce any such person, concern or entity
to cease being a customer or supplier of the Company. 
 6. Non-Competition. I agree that, during the term of my
relationship with the Company (whether as an employee, consistent or otherwise), and for a period of twelve (12) months immediately following the termination of my relationship with the Company for any reason, with or without cause (the
“Non-Compete Period”), I will not, without the prior written consent of the Company, for myself or on behalf of any other person or entity, directly or indirectly, either as principal, agent, employee, consultant, representative or
in any other capacity, own, manage, operate or control, or be connected or employed by, or otherwise associate in any manner with, or

  

 CONFIDENTIALITY, NON-COMPETITION AND INVENTION ASSIGNMENT AGREEMENT 
 3 

 
engage in, any business located anywhere in the world that is in the field of tissue engineering and organ regeneration and is developing a product or products (in any stage, whether preliminary
or final) that competes or will compete, directly or indirectly, with any product or products (in any stage of development, whether preliminary or final) of the Company as contemplated during the Employment Period (the “Field of
Interest”). More ownership of one-half of one percent or less of the outstanding capital stock or other ownership interests of any entity whose securities are traded on a recognized securities exchange will not, in itself, constitute a
violation of this Section 6. 
 7. Reasonableness of Restrictions. I recognize and acknowledge that the restrictions
and limitations set forth in this Agreement, including such provisions set forth in Sections 5 and 6 above, are legitimate and fair in light of any access to Confidential Information, my substantial contacts with customers of the
Company and the Company’s need to develop, market and sell its services and/or products. I further acknowledge that the restrictions and limitations set forth in this Agreement will in no way interfere with my ability to earn a living following
the termination of my employment with the Company and that my ability to earn a livelihood without violating such restrictions is a material condition to my employment with the Company. 
 8. Independence. Each of the rights enumerated above shall be independent of the others and shall be in addition to and not in lieu
of any other rights and remedies available to the Company at law or in equity. No breach by the Company of any of its obligations hereunder, or otherwise shall operate to excuse the performance of my commitments hereunder. 
 9. Severability and Judicial Modification. If any provision or covenant (or both) contained herein or any part of any of them is
hereafter construed or adjudicated to be invalid or unenforceable, the same shall not affect the remainder of the provisions or covenants (or both) or rights or remedies (or both), which shall be given full affect without regard to the invalid or
unenforceable portions. Additionally, in the event any provision or covenant (or both) contained herein is held to be invalid or unenforceable because of the duration, area, scope, activity and/or subject contemplated under such provision or
covenant (or both), I agree that the court making such determination shall have the power to reduce the applicable duration, area, scope, activity or subject (or any combination of any of the foregoing) to the maximum or broadest extent permissible
by law and that, in its reduced forte, the provision or covenant (or both) in question shall then be enforceable. I further acknowledge that in the event any provision or covenant (or both) contained herein or any part of any of them is hereafter
construed or adjudicated to be invalid or unenforceable in any particular jurisdiction, then, any such invalidity or unenforceability shall not invalidate or render unenforceable such provision and/or covenants in any other jurisdiction. 

10. Injunctive Relief. I expressly acknowledge that any breach or threatened breach of any of the terms and/or conditions set
forth in this Agreement may result in substantial, continuing and irreparable injury to the Company. Therefore, I hereby agree that, in addition to any other remedy that may be available to the Company, the Company may be entitled to injunctive
relief, specific performance or other equitable relief by a court of appropriate jurisdiction in the event of any breach or threatened breach of the terms of this Agreement. Notwithstanding any other provisions to the contrary, I acknowledge and
agree that the Restricted Period or the Non-Corporate Period, as applicable, shall be toiled and shall not run during any period for violation of any of the covenants in Section 5 or Section 6 hereof and during any other
period required for litigation during which the Company seeks to enforce such covenants against me if it is ultimately determined that I was in breach of such covenants. 
 11. General Provisions. 
 (a) Governing Law and Forum Selection. The
validity, interpretation, construction and performance of this Agreement shall be governed by the laws of the United States of America and the Commonwealth of Pennsylvania, without giving effect to the principles of conflict of laws, I agree that
any disputes that may arise from this Agreement shall be resolved in State or Federal courts located in the Commonwealth of Pennsylvania, exclusively, and consent to the Jurisdiction of such courts. 
 (b) Notices. All notices or other communications given hereunder shall be in writing and shall be deemed effective upon delivery at
the address of the party to be notified and shall be mailed by certified or registered mail, return receipt requested, delivered by courier, telecopied, or sent by other facsimile method (notices

	RE:	Acceptance of Employment 

 I
represent that to the best of my understanding, I am under no common law or contractual obligation that would be an impediment to my employment with Tengion, Inc. (the “Company”), I will not use or disclose any confidential, proprietary or
trade secret information belonging to any former employee, during my employment with the Company. 
 I represent and warrant
that I have no retained or copied any confidential, proprietary or trade secret information or property, in any form, belonging to any former employee, and that if I was in possession of any such information or property, I have returned it to my
former employer(s). 
 I agree that, if at any time during my employment with the Company, I am at risk of using or disclosing
any confidential, proprietary or trade secret information belonging to any former employer, I will immediately recuse myself from acting on the matter and advise the President and CEO of the Company, without revealing any protected information, the
nature of my conflict; provided, however, that I will not be required to recuse myself in the event such disclosure is required by law or regulation or as a result of a response to a valid order of a court or another governmental body of the United
States or any political subdivision thereof. 
 I understand that if any of the representatives or warranties herein are
intentionally false, or if I violate any of the terms of this memorandum, I will forfeit any unvested portion of the unvested stock incentives awarded or issued to me.
