    (a)          Asterias agrees to employ Executive
        in the position described on Exhibit A (which Exhibit A is a part of this Agreement) effective as of the date of this Agreement. Executive shall perform the duties and functions described on Exhibit A and such other duties as the executive(s) to
        whom Executive reports or the Board of Directors of Asterias may from time to time determine. Executive shall devote Executive’s best efforts, skills, and abilities, on a full‐time basis, exclusively to the business of Asterias and its Related
        Companies pursuant to, and in accordance with, business policies and procedures, as fixed from time to time by the Board of Directors (the “Policies”). Executive covenants and agrees that Executive will faithfully adhere to and fulfill the
        Policies, including any changes to the Policies that may be made in the future. Executive may be provided with a copy of Asterias’ employee manual (the “Manual”) which contains the Policies. Asterias may change its Policies from time to time, in
        which case Executive will be notified of the changes in writing by a memorandum, a letter, or an update or revision of Asterias’s employee manual.

    

    

    (b)          Performance of Services for Related Companies. In addition to the performance of services for Asterias, Executive shall, to the extent so required by Asterias, also perform services for
        one or more members of a consolidated group of which Asterias is a part ("Related Company"), provided that such services are consistent with the kind of services Executive performs or may be required to perform for Asterias under this Agreement. If
        Executive performs any services for any Related Company, Executive shall not be entitled to receive any compensation or remuneration in addition to or in lieu of the compensation and remuneration provided under this Agreement on account of such
        services for the Related Company. The Policies will govern Executive’s employment by Asterias and any Related Companies for which Executive is asked to provide Services. In addition, Executive covenants and agrees that Executive will faithfully
        adhere to and fulfill such additional policies as may established from time to time by the board of directors of any Related Company for which Executive performs services, to the extent that such policies and procedures differ from or are in
        addition to the Policies adopted by Asterias.

    

    

    (c)          No Conflicting Obligations. Executive represents and warrants to Asterias and each Related Company that Executive is under no obligations or commitments, whether contractual or otherwise,
        that are inconsistent with Executive’s obligations under this Agreement or that would prohibit Executive, contractually or otherwise, from performing Executive’s duties as under this Agreement and the Policies.

    

    

    (d)          No Unauthorized Use of Third Party Intellectual Property. Executive represents and warrants to Asterias and each Related Company that Executive will not use or disclose, in connection
        with Executive’s employment by Asterias or any Related Company, any patents, trade secrets, confidential information, or other proprietary information or intellectual property as to which any other person has any right, title or interest, except to
        the extent that Asterias or a Related Company holds a valid license or other written permission for such use from the owner(s) thereof. Executive represents and warrants to Asterias and each Related Company that Executive has returned all property
        and confidential information belonging to any prior employer.

     

    
      
        

    

    
    2.          Compensation

    

    

    (a)          Salary. During the term of this Agreement, Asterias shall pay to the Executive the salary shown on Exhibit A. Executive's salary shall be paid in equal semi-monthly
        installments, consistent with Asterias’s regular salary payment practices. Executive's salary may be increased from time-to-time by Asterias, in Asterias’s sole and absolute discretion, without affecting this Agreement.

    

    

    (b)          Bonus. Executive may be eligible for an annual bonus, as may be approved by
        the Board of Directors in its discretion, based on Executive's performance and achievement of goals or milestones set by the Board of Directors from time to time. Executive agrees that the Board of Directors of Asterias may follow the
        recommendations of the Compensation Committee of the board of directors of Asterias’s parent company in determining whether to a award bonus or to establish performance goals or milestones. Executive also agrees that the Board of Directors and
        Asterias are not obligated to adopt any bonus plan, to maintain in effect any bonus plan that may now be in effect or that may be adopted during the term of Executive’s employment, or to pay Executive a bonus unless a bonus is earned under the
        terms and conditions of any bonus plan adopted by Asterias.

    

    

    (c)          Expense Reimbursements. Asterias or a Related Company shall reimburse Executive for reasonable travel and other business expenses (but not expenses of commuting to
        work) incurred by Executive in the performance of Executive’s duties under this Agreement, subject to the Policies and procedures in effect from time to time, and provided that Executive submits supporting vouchers.

    

    

    (d)          Benefit Plans. Executive may be eligible (to the extent Executive qualifies) to participate in certain retirement, pension, life, health, accident and disability
        insurance, stock option plan or other similar employee benefit plans which may be adopted by Asterias (or a Related Company) for its employees. Asterias and the Related Companies have the right, at any time and without any amendment of this
        Agreement, and without prior notice to or consent from Executive, to adopt, amend, change, or terminate any such benefit plans that may now be in effect or that may be adopted in the future, in each case without any further financial obligation to
        Executive. Any benefits to which Executive may be entitled under any benefit plan shall be governed by the terms and conditions of the applicable benefit plan, and any related plan documents, as in effect from time to time. If Executive receives
        any grant of stock options or restricted stock under any stock option plan or stock purchase plan of Asterias or any Related Company, the terms and conditions of the stock options or restricted stock, and Executive’s rights with respect to the
        stock options or restricted stock, shall be governed by (i) the terms of the applicable stock option or stock purchase plan, as the same may be amended from time to time, and (ii) the terms and conditions of any stock option agreement or stock
        purchase agreement and related agreements that Executive may sign or be required to sign with respect to the stock options or restricted stock.

    

    

    (e)          Vacation; Sick Leave. Executive shall be entitled to the number of days of vacation and sick leave (without reduction in compensation) during each calendar year shown
        on Exhibit A or as may be provided by the Policies. Executive’s vacation shall be taken at such time as is consistent with the needs and Policies of Asterias and its Related Companies. All vacation days and sick leave days shall accrue annually
        based upon days of service. Executive’s right to leave from work due to illness is subject to the Policies and the provisions of this Agreement governing termination due to disability, sickness or illness. The Policies governing the disposition of
        unused vacation days and sick leave days remaining at the end of Asterias's fiscal year shall govern whether unused vacation days or sick leave days will be paid, lost, or carried over into subsequent fiscal years.

    3.          Competitive Activities. During the term of Executive's employment, and for one year thereafter, Executive shall not, for Executive or any third party, directly or indirectly employ,
        solicit for employment or recommend for employment any person employed by Asterias or any Related Company. During the term of Executive's employment, Executive shall not, directly or indirectly as an employee, contractor, officer, director, member,
        partner, agent, or equity owner, engage in any activity or business that competes or could reasonably be expected to compete with the business of Asterias or any Related Company. Executive acknowledges that there is a substantial likelihood that
        the activities described in this Section would (a) involve the unauthorized use or disclosure of Asterias's or a Related Company's Confidential Information and that use or disclosure would be extremely difficult to detect, and (b) result in
        substantial competitive harm to the business of Asterias or a Related Company. Executive has accepted the limitations of this Section as a reasonably practicable and unrestrictive means of preventing such use or disclosure of Confidential
        Information and preventing such competitive harm.

    

    

    4.          Inventions/Intellectual
        Property/Confidential Information

    

    

    (a)          As used in this Agreement,
        “Intellectual Property” means any and all inventions, discoveries, formulas, improvements, writings, designs, or other intellectual property. Any and all Intellectual Property relating to or in any way pertaining to or connected with the systems,
        products, apparatus, or methods employed, manufactured, constructed, or researched by Asterias, or any Related Company, which Executive may conceive or make while performing services for Asterias or a Related Company shall be the sole and exclusive
        property of Asterias or the applicable Related Company. Executive hereby irrevocably assigns and transfers to Asterias, or a Related Company, all rights, title and interest in and to all Intellectual Property that Executive may now or in the future
        have under patent, copyright, trade secret, trademark or other law, in perpetuity or for the longest period otherwise permitted by law, without the necessity of further consideration. Asterias and the Related Companies will be entitled to obtain
        and hold in their own name all copyrights, patents, trade secrets, trademarks and other similar registrations with respect to such Intellectual Property.

    

    

    (b)          Moral Rights. To the extent allowed by law, the rights to Intellectual Property assigned by Executive to Asterias or any Related Company includes all rights of
        paternity, integrity, disclosure and withdrawal, and any other rights that may be known as or referred to as “moral rights,” “artist’s rights,” “droit moral,” or the like (collectively “Moral Rights”). To the extent Executive retains any such Moral
        Rights under applicable law, Executive hereby ratifies and consents to any action that may be taken with respect to such Moral Rights by or authorized by Asterias or a Related Company and agrees not to assert any Moral Rights with respect thereto.
        Executive shall confirm in writing any such ratifications, consents, and agreements from time to time as requested by Asterias or Related Company.

    

    

    (c)          Execution of Documents; Power of Attorney. Executive agrees to execute and sign any and all applications, assignments, or other instruments which Asterias or a Related
        Company may deem necessary in order to enable Asterias or a Related Company, at its expense, to apply for, prosecute, and obtain patents of the United States or foreign countries for the Intellectual Property, or in order to assign or convey to,
        perfect, maintain or vest in Asterias or a Related Company the sole and exclusive right, title, and interest in and to the Intellectual Property. If Asterias or a Related Company is unable after reasonable efforts to secure Executive’s signature,
        cooperation or assistance in accordance with the preceding sentence, whether because of Executive’s incapacity or any other reason whatsoever, Executive hereby designates and appoints Asterias or any Related Company or its designee as Executive’s
        agent and attorney-in-fact, to act on Executive’s behalf, to execute and file documents and to do all other lawfully permitted acts necessary or desirable to perfect, maintain or otherwise protect Asterias’s or a Related Company’s rights in the
        Intellectual Property. Executive acknowledges and agrees that such appointment is coupled with an interest and is irrevocable.

     

    
      3

      
        

    

    (d)          Disclosure of Intellectual Property. Executive agrees to disclose promptly to
        Asterias or a Related Company all Intellectual Property which Executive may create or conceive solely, jointly, or commonly with others. This paragraph is applicable whether or not the Intellectual Property was made under the circumstances
        described in paragraph (a) of this Section. Executive agrees to make such disclosures understanding that they will be received in confidence and that, among other things, they are for the purpose of determining whether or not rights to the related
        Intellectual Property is the property of Asterias or a Related Company.

    

    

    (e)          Limitations. The obligations provided for by this Section 4, except for the requirements as to disclosure in paragraph 4(d), do not apply to any rights Executive may
        have acquired in connection with Intellectual Property for which no equipment, supplies, facility, or trade secret information of Asterias or a Related Company was used and which was developed entirely on the Executive’s own time and (i) which at
        the time of conception or reduction to practice does not relate directly or indirectly to the business of Asterias or a Related Company, or to the actual or demonstrable anticipated research or development activities or plans of Asterias or a
        Related Company, or (ii) which does not result from any work performed by Executive for Asterias or a Related Company. All Intellectual Property that (1) results from the use of equipment, supplies, facilities, or trade secret information of
        Asterias or a Related Company; (2) relates, at the time of conception or reduction to practice of the invention, to the business of Asterias or a Related Company, or actual or demonstrably anticipated research or development of Asterias or a
        Related Company; or (3) results from any work performed by Executive for Asterias or a Related Company shall be assigned and is hereby assigned to Asterias or the applicable Related Company. The parties understand and agree that this limitation is
        intended to be consistent with California Labor Code, Section 2870, a copy of which is attached as Exhibit A. If Executive wishes to clarify that something created by Executive prior to Executive’s employment by Asterias or a Related Company that
        relates to the actual or proposed business of Asterias or a Related Company is not within the scope of this Agreement, Executive has listed it on Exhibit B in a manner that does not violate any third party rights.

        venture partners; research collaborators; licensees; and financial information. Confidential Information also shall include any information of any kind, whether belonging to Asterias, a Related Company, or any third party, that Asterias or a

        unauthorized disclosure by Executive; (ii) information that was rightfully in Executive's possession prior to Executive’s employment with Asterias and was not assigned to Asterias or a Related Company or was not disclosed to Executive in
        Executive’s capacity as a director or other fiduciary of Asterias or a Related Company; or (iii) information disclosed to Executive, after the termination of Executive’s employment by Asterias, without a confidential restriction by a third party
        who rightfully possesses the information and did not obtain it, either directly or indirectly, from Asterias or a Related Company, and who is not subject to an obligation to keep such information confidential for the benefit of Asterias, a Related
        Company, or any third party with whom Asterias or a Related Company has a contractual relationship. Executive understands and agrees that all Confidential Information shall be kept confidential by Executive both during and after Executive’s
        employment by Asterias or any Related Company. Executive further agrees that Executive will not, without the prior written approval by Asterias or a Related Company, disclose any Confidential Information, or use any Confidential Information in any

    EXECUTIVE UNDERSTANDS AND AGREES THAT THIS AGREEMENT TO ARBITRATE CONSTITUTES A WAIVER OF EMPLOYEE’S RIGHT TO A TRIAL BY JURY OF ANY MATTERS COVERED
        BY THIS AGREEMENT TO ARBITRATE.

        enforceable and all other provisions shall nevertheless continue to be valid and enforceable as though the invalid or unenforceable parts had not been included in this Agreement or the Policies. In the event that any provision relating to a time
        period of restriction shall be declared by a court of competent jurisdiction to exceed the maximum time period such court deems reasonable and enforceable, then the time period of restriction deemed reasonable and enforceable by the court shall
        become and shall thereafter be the maximum time period.

    

    

    9.          Agreement Read and Understood. Executive acknowledges that Executive has carefully read the terms of this Agreement, that Executive has had an opportunity to consult with an attorney or
        other representative of Executive’s own choosing regarding this Agreement, that Executive understands the terms of this Agreement, and that Executive is entering this agreement of Executive’s own free will.

        Agreement may be modified, amended, or waived except by a written document signed both by Asterias and Executive.

        upon condition that the assignee shall assume, either expressly or by operation of law, all of Asterias's obligations under this Agreement.

    

    

    13.          Survival. This Section 13 and the covenants and agreements contained in Sections 4 and 6 of this Agreement shall survive termination of this Agreement and Executive's employment.

    AMENDED AND RESTATED EMPLOYMENT AGREEMENT

    

    

    THIS AMENDED AND RESTATED EMPLOYMENT AGREEMENT (“Agreement”) is made as of November 7, 2018 by and between Asterias BioTherapeutics
        (“Asterias”), a California corporation, and Edward Wirth, III ("Executive"), and shall be effective and replace that certain employment agreement dated June 16, 2013 by and between Asterias and Executive at the time that is immediately prior to the
        consummation of the proposed transaction between Asterias and BioTime, Inc.

    

    

    1.          Engagement;
        Position and Duties.

    

    

    (a)          Asterias agrees to employ Executive
        in the position described on Exhibit A (which Exhibit A is a part of this Agreement) effective as of the date of this Agreement. Executive shall perform the duties and functions described on Exhibit A and such other duties as the executive(s) to
        whom Executive reports or the Board of Directors of Asterias may from time to time determine. Executive shall be employed by Asterias on a full-time basis unless Exhibit A provides for part-time employment. Executive shall devote Executive’s best
        efforts, skills, and abilities to the business of Asterias and its Related Companies pursuant to, and in accordance with, business policies and procedures, as fixed from time to time by the Board of Directors (the “Policies”). Executive covenants
        and agrees that Executive will faithfully adhere to and fulfill the Policies, including any changes to the Policies that may be made in the future. Executive may be provided with a copy of Asterias’s employee manual (the “Manual”) which contains
        the Policies. Asterias may change its Policies from time to time, in which case Executive will be notified of the changes in writing by a memorandum, a letter, or an update or revision of the Manual.

    

    

    (b)          Performance of Services for Related Companies. In addition to the performance of services for Asterias, Executive shall, to the extent so required by Asterias, also perform services for
        one or more members of a consolidated group of which Asterias is a part ("Related Company"), provided that such services are consistent with the kind of services Executive performs or may be required to perform for Asterias under this Agreement. If
        Executive performs any services for any Related Company, Executive shall not be entitled to receive any compensation or remuneration in addition to or in lieu of the compensation and remuneration provided under this Agreement on account of such
        services for the Related Company. The Policies will govern Executive’s employment by Asterias and any Related Companies for which Executive is asked to provide Services. In addition, Executive covenants and agrees that Executive will faithfully
        adhere to and fulfill such additional policies as may established from time to time by the board of directors of any Related Company for which Executive performs services, to the extent that such policies and procedures differ from or are in
        addition to the Policies adopted by Asterias.

    

    

    (c)          No Conflicting Obligations. Executive represents and warrants to Asterias and each Related Company that Executive is under no obligations or commitments, whether contractual or otherwise,
        that are inconsistent with Executive’s obligations under this Agreement or that would prohibit Executive, contractually or otherwise, from performing Executive’s duties as under this Agreement and the Policies.

    

    

    (d)          No Unauthorized Use of Third Party Intellectual Property. Executive represents and warrants to Asterias and each Related Company that Executive will not use or disclose, in connection
        with Executive’s employment by Asterias or any Related Company, any patents, trade secrets, confidential information, or other proprietary information or intellectual property as to which any other person has any right, title or interest, except to
        the extent that Asterias or a Related Company holds a valid license or other written permission for such use from the owner(s) thereof. Executive represents and warrants to Asterias and each Related Company that Executive has returned all property
        and confidential information belonging to any prior employer.

     

    
      
        

    

    
    2.          Compensation

    

    

    (a)          Salary. During the term of this Agreement, Asterias shall pay to the Executive the salary shown on Exhibit A. Executive's salary shall be paid in equal semi-monthly
        installments, consistent with Asterias’s regular salary payment practices. Executive e's salary may be increased from time-to-time by Asterias, in Asterias’s sole and absolute discretion, without affecting this Agreement.

    

    

    (b)          Bonus. Executive may be eligible for an annual bonus, as may be approved by
        the Board of Directors in its discretion, based on Executive's performance and achievement of goals or milestones set by the Board of Directors from time to time. Executive agrees that the Board of Directors of Asterias may follow the
        recommendations of the Compensation Committee of the board of directors of Asterias’s parent company in determining whether to a award bonus or to establish performance goals or milestones. Executive also agrees that the Board of Directors and
        Asterias are not obligated to adopt any bonus plan, to maintain in effect any bonus plan that may now be in effect or that may be adopted during the term of Executive’s employment, or to pay Executive a bonus unless a bonus is earned under the
        terms and conditions of any bonus plan adopted by Asterias.

    

    

    (c)          Expense Reimbursements. Asterias or a Related Company shall reimburse Executive for reasonable travel and other business expenses (but not expenses of commuting to
        work) incurred by Executive in the performance of Executive’s duties under this Agreement, subject to the Policies and procedures in effect from time to time, and provided that Executive submits supporting vouchers.

    

    

    (d)          Benefit Plans. Executive may be eligible (to the extent Executive qualifies) to participate in certain retirement, pension, life, health, accident and disability
        insurance, stock option plan or other similar employee benefit plans which may be adopted by Asterias (or a Related Company) for its employees. Asterias and the Related Companies have the right, at any time and without any amendment of this
        Agreement, and without prior notice to or consent from Executive, to adopt, amend, change, or terminate any such benefit plans that may now be in effect or that may be adopted in the future, in each case without any further financial obligation to
        Executive. Any benefits to which Executive may be entitled under any benefit plan shall be governed by the terms and conditions of the applicable benefit plan, and any related plan documents, as in effect from time to time. If Executive receives
        any grant of stock options or restricted stock under any stock option plan or stock purchase plan of Asterias or any Related Company, the terms and conditions of the stock options or restricted stock, and Executive’s rights with respect to the
        stock options or restricted stock, shall be governed by (i) the terms of the applicable stock option or stock purchase plan, as the same may be amended from time to time, and (ii) the terms and conditions of any stock option agreement or stock
        purchase agreement and related agreements that Executive may sign or be required to sign with respect to the stock options or restricted stock.

    

    

    (e)          Vacation; Sick Leave. Executive shall be entitled to the number of days of vacation and sick leave (without reduction in compensation) during each calendar year shown
        on Exhibit A or as may be provided by the Policies. Executive’s vacation shall be taken at such time as is consistent with the needs and Policies of Asterias and its Related Companies. All vacation days and sick leave days shall accrue annually
        based upon days of service. Executive’s right to leave from work due to illness is subject to the Policies and the provisions of this Agreement governing termination due to disability, sickness or illness. The Policies governing the disposition of
        unused vacation days and sick leave days remaining at the end of Asterias's fiscal year shall govern whether unused vacation days or sick leave days will be paid, lost, or carried over into subsequent fiscal years.

     

    
      2

      
        

    

    3.          Competitive Activities. During the term of Executive 's employment, and for one year thereafter, Executive shall not, for Executive or any third party, directly or indirectly employ,
        solicit for employment or recommend for employment any person employed by Asterias or any Related Company. During the term of Executive's employment, Executive shall not, directly or indirectly as an employee, contractor, officer, director, member,
        partner, agent, or equity owner, engage in any activity or business that competes or could reasonably be expected to compete with the business of Asterias or any Related Company. Executive acknowledges that there is a substantial likelihood that
        the activities described in this Section would (a) involve the unauthorized use or disclosure of Asterias's or a Related Company's Confidential Information and that use or disclosure would be extremely difficult to detect, and (b) result in
        substantial competitive harm to the business of Asterias or a Related Company. Executive has accepted the limitations of this Section as a reasonably practicable and unrestrictive means of preventing such use or disclosure of Confidential
        Information and preventing such competitive harm.

    

    

    4.          Inventions/Intellectual
        Property/Confidential Information

    

    

    (a)          As used in this Agreement,
        “Intellectual Property” means any and all inventions, discoveries, formulas, improvements, writings, designs, or other intellectual property. Any and all Intellectual Property relating to or in any way pertaining to or connected with the systems,
        products, apparatus, or methods employed, manufactured, constructed, or researched by Asterias, or any Related Company, which Executive may conceive or make while performing services for Asterias or a Related Company shall be the sole and exclusive
        property of Asterias or the applicable Related Company. Executive hereby irrevocably assigns and transfers to Asterias, or a Related Company, all rights, title and interest in and to all Intellectual Property that Executive may now or in the future
        have under patent, copyright, trade secret, trademark or other law, in perpetuity or for the longest period otherwise permitted by law, without the necessity of further consideration. Asterias and the Related Companies will be entitled to obtain
        and hold in their own name all copyrights, patents, trade secrets, trademarks and other similar registrations with respect to such Intellectual Property.

    

    

    (b)          Moral Rights. To the extent allowed by law, the rights to Intellectual Property assigned by Executive to Asterias or any Related Company includes all rights of
        paternity, integrity, disclosure and withdrawal, and any other rights that may be known as or referred to as “moral rights,” “artist’s rights,” “droit moral,” or the like (collectively “Moral Rights”). To the extent Executive retains any such Moral
        Rights under applicable law, Executive hereby ratifies and consents to any action that may be taken with respect to such Moral Rights by or authorized by Asterias or a Related Company and agrees not to assert any Moral Rights with respect thereto.
        Executive shall confirm in writing any such ratifications, consents, and agreements from time to time as requested by Asterias or Related Company.

    

    

    (c)          Execution of Documents; Power of Attorney. Executive agrees to execute and sign any and all applications, assignments, or other instruments which Asterias or a Related
        Company may deem necessary in order to enable Asterias or a Related Company, at its expense, to apply for, prosecute, and obtain patents of the United States or foreign countries for the Intellectual Property, or in order to assign or convey to,
        perfect, maintain or vest in Asterias or a Related Company the sole and exclusive right, title, and interest in and to the Intellectual Property. If Asterias or a Related Company is unable after reasonable efforts to secure Executive’s signature,
        cooperation or assistance in accordance with the preceding sentence, whether because of Executive’s incapacity or any other reason whatsoever, Executive hereby designates and appoints Asterias or any Related Company or its designee as Executive’s
        agent and attorney-in-fact, to act on Executive’s behalf, to execute and file documents and to do all other lawfully permitted acts necessary or desirable to perfect, maintain or otherwise protect Asterias’s or a Related Company’s rights in the
        Intellectual Property. Executive acknowledges and agrees that such appointment is coupled with an interest and is irrevocable.

     

    
      3

      
        

    

    (d)          Disclosure of Intellectual Property. Executive agrees to disclose promptly to
        Asterias or a Related Company all Intellectual Property which Executive may create or conceive solely, jointly, or commonly with others. This paragraph is applicable whether or not the Intellectual Property was made under the circumstances
        described in paragraph (a) of this Section. Executive agrees to make such disclosures understanding that they will be received in confidence and that, among other things, they are for the purpose of determining whether or not rights to the related
        Intellectual Property is the property of Asterias or a Related Company.

    

    

    (e)          Limitations. The obligations provided for by this Section 4, except for the requirements as to disclosure in paragraph 4(d), do not apply to any rights Executive may
        have acquired in connection with Intellectual Property for which no equipment, supplies, facility, or trade secret information of Asterias or a Related Company was used and which was developed entirely on the Executive’s own time and (i) which at
        the time of conception or reduction to practice does not relate directly or indirectly to the business of Asterias or a Related Company, or to the actual or demonstrable anticipated research or development activities or plans of Asterias or a
        Related Company, or (ii) which does not result from any work performed by Executive for Asterias or a Related Company. All Intellectual Property that (1) results from the use of equipment, supplies, facilities, or trade secret information of
        Asterias or a Related Company; (2) relates, at the time of conception or reduction to practice of the invention, to the business of Asterias or a Related Company, or actual or demonstrably anticipated research or development of Asterias or a
        Related Company; or (3) results from any work performed by Executive for Asterias or a Related Company shall be assigned and is hereby assigned to Asterias or the applicable Related Company. The parties understand and agree that this limitation is
        intended to be consistent with California Labor Code, Section 2870, a copy of which is attached as Exhibit A. If Executive wishes to clarify that something created by Executive prior to Executive’s employment by Asterias or a Related Company that
        relates to the actual or proposed business of Asterias or a Related Company is not within the scope of this Agreement, Executive has listed it on Exhibit B in a manner that does not violate any third party rights.

    

    

    (f)          Confidential and Proprietary Information. During Executive’s employment,
        Executive will have access to trade secrets and confidential information of Asterias and one or more Related Companies. Confidential Information means all information and ideas, in any form, relating in any manner to matters such as: products;
        formulas; technology and know-how; inventions; clinical trial plans and data; business plans; marketing plans; the identity, expertise, and compensation of employees and contractors; systems, procedures, and manuals; customers; suppliers; joint
        venture partners; research collaborators; licensees; and financial information. Confidential Information also shall include any information of any kind, whether belonging to Asterias, a Related Company, or any third party, that Asterias or a
        Related Company has agreed to keep secret or confidential under the terms of any agreement with any third party. Confidential Information does not include: (i) information that is or becomes publicly known through lawful means other than
        unauthorized disclosure by Executive; (ii) information that was rightfully in Executive 's possession prior to Executive’s employment with Asterias and was not assigned to Asterias or a Related Company or was not disclosed to Executive in
        Executive’s capacity as a director or other fiduciary of Asterias or a Related Company; or (iii) information disclosed to Executive, after the termination of Executive’s employment by Asterias, without a confidential restriction by a third party
        who rightfully possesses the information and did not obtain it, either directly or indirectly, from Asterias or a Related Company, and who is not subject to an obligation to keep such information confidential for the benefit of Asterias, a Related
        Company, or any third party with whom Asterias or a Related Company has a contractual relationship. Executive understands and agrees that all Confidential Information shall be kept confidential by Executive both during and after Executive’s
        employment by Asterias or any Related Company. Executive further agrees that Executive will not, without the prior written approval by Asterias or a Related Company, disclose any Confidential Information, or use any Confidential Information in any
        way, either during the term of Executive’s employment or at any time thereafter, except as required by Asterias or a Related Company in the course of Executive’s employment.

    5.          Termination of Employment. Employee understands and agrees that Employee’s employment has no specific term. This Agreement, and the employment relationship, are “at will” and may be
        terminated by Employee or by Asterias (and the employment of Employee by any Related Company may be terminated by the Related Company) with or without cause at any time by notice given in writing. Except as otherwise agreed in writing or as
        otherwise provided in this Agreement, upon termination of Employee’s employment, Asterias and the Related Companies shall have no further obligation to Employee by way of compensation or otherwise as expressly provided in this Agreement or in any
        separate employment agreement that might then exist between Employee and Asterias or any Related Company.

    

    

    (a)          Payments Due Upon Termination of Employment. Upon termination of Employee’s employment with Asterias and all Related Companies at any time and for any reason, Employee will be entitled to

    (i)          Termination for Cause, Death, Disability, or Resignation. In the event that the employment of Employee is terminated for Cause, or is terminated as a result of death, Disability, or
        resignation without “Good Reason” as defined in this Agreement, Employee will be entitled to receive payment for all accrued but unpaid salary, accrued but unpaid bonus, if any, and vacation accrued as of the date of termination of Employee’s
        employment. Employee will not be entitled to any cash severance benefits or vesting of any stock options or other equity or cash awards.

    

    

    (ii)          Termination Without Cause and Resignation for Good Reason. In the event that the employment of Employee is terminated by Asterias without “Cause” as defined in this Agreement or Employee
        resigns for “Good Reason,” as defined in this Agreement otherwise than within twelve (12) months following a “Change in Control” as defined in this Agreement, Employee shall receive payment for all accrued but unpaid salary, accrued but unpaid
        bonus, if any, and vacation accrued as of the date of termination of Employee’s employment, and as severance compensation salary continuation at Employee’s then-current base salary for twelve (12) months. The salary continuation described in this
        paragraph shall begin as soon as practicable after the effective date of Employee’s separation agreement, no later than 60 days after the date of Employee’s termination of employment, subject to such payroll deductions and withholdings as are
        required by law. This paragraph shall not apply to (x) termination of Employee’s employment by a Related Company if Employee remains employed by Asterias or another Related Company, or (y) termination of Employee’s employment by Asterias if
        Employee remains employed by a Related Company.

     

    
      5

      
        

    

    (iii)          Change of Control. In the event Asterias (or any successor in interest to Asterias that has assumed Asterias’ obligation under this Agreement) terminates Employee’s employment without
        “Cause” or Employee resigns for “Good Reason” within twelve (12) months following a Change in Control, Employee will be entitled to receive payment for all accrued but unpaid salary, accrued but unpaid bonus, if any, and vacation accrued as of the
        date of termination of Employee’s employment, and as severance compensation (A) an amount equal to twelve (12) months of Employee’s base salary, which shall be paid in a lump sum no later than 60 days after the date of Employee’s termination of
        employment, subject to such payroll deductions and withholdings as are required by law, (B) bonus for the year in which Executive’s employment terminated based on actual performance and payable (at the discretion of the Company, in cash or in
        shares of common stock of the Company or its parent company) when annual bonus payments are payable to other members of senior management and pro-rated to reflect the portion of the year during which the Executive performed services, (C)
        accelerated vesting of 100% of Employee’s then unvested stock options and any restricted stock, and (D) payment, for a period of six (6) months, of any health insurance benefits that Employee was receiving at the time of termination of Employee’s
        employment, under an Asterias employee health insurance plan subject to COBRA.

    

    

    (b)          Release. Any other provision of this Agreement notwithstanding, paragraphs (a)(ii) and (a)(iii) of this Section shall not apply unless Employee (i) has executed a separation agreement
        including a general release of all claims against Asterias or its successor in interest (in a form prescribed by Asterias or its successor in interest) and (ii) has returned all property in Employee’s possession belonging Asterias or its successor

        period of restriction shall be declared by a court of competent jurisdiction to exceed the maximum time period such court deems reasonable and enforceable, then the time period of restriction deemed reasonable and enforceable by the court shall
        become and shall thereafter be the maximum time period.
