C. The board of directors of Asterias (the “Asterias Board of Directors”) (by unanimous vote of the disinterested members of the Asterias Board of Directors), acting upon the unanimous recommendation of a committee of the Asterias Board of Directors consisting only of independent and disinterested directors of Asterias (the “Asterias Special Committee”), has approved the Merger and the other transactions contemplated by this Agreement (the “Transactions”), approved this Agreement and declared its advisability, and resolved to recommend that Asterias’ stockholders adopt this Agreement pursuant to Section 251 of the DGCL;

G. The Parties desire to make certain representations, warranties, covenants and agreements in connection with the Merger and prescribe certain conditions to the Merger.

In consideration of the mutual covenants and agreements contained in this Agreement and for other good and valuable consideration, the receipt and adequacy of which are hereby acknowledged, the Parties agree as follows:

Article I

The Merger

Section 1.1 The Merger. Upon the terms and subject to the satisfaction or waiver of the conditions set forth in this Agreement and in accordance with the DGCL, Merger Sub will be merged with and into Asterias, whereupon the separate existence of Merger Sub will cease and Asterias will continue as the surviving entity in the Merger (the “Surviving Corporation”), such that following the Merger, the Surviving Corporation will be a subsidiary of BioTime. The Merger will have the effects provided in this Agreement and as specified in the DGCL.

Section 1.2 Closing. The closing of the Merger (the “Closing”) will take place at 7:00 a.m., Pacific Time, at the offices of Cooley LLP, 3175 Hanover Street, Palo Alto, California, on the second business day after the satisfaction or waiver of the last of the conditions set forth in Article VII to be satisfied or waived (other than any such conditions that by their nature are to be satisfied at the Closing, but subject to the satisfaction or waiver of such conditions at the Closing), unless another date or place is agreed to in writing by Asterias and BioTime. The date on which the Closing actually takes place is referred to as the “Closing Date”.

Section 1.3 Effective Time. On the Closing Date, the Parties will cause a certificate of merger with respect to the Merger (the “Certificate of Merger”) to be duly executed and filed with the DSOS as provided under the DGCL and make any other filings, recordings or publications required to be made by Asterias or Merger Sub under the DGCL in connection with the Merger. The Merger will become effective at such time as the Certificate of Merger is duly filed with the DSOS or on such other date and time as will be agreed to by Asterias and BioTime and specified in the Certificate of Merger (such date and time being hereinafter referred to as the “Effective Time”).

Section 1.4 Certificate of Incorporation; Bylaws. At the Effective Time and subject to Section 6.4 the certificate of incorporation of Merger Sub, as in effect immediately prior to the Effective Time, will be the certificate of incorporation of the Surviving Corporation until thereafter amended as provided by the DGCL and such certificate of incorporation, except that Article I of the certificate of incorporation of the Surviving Corporation will be amended as of the Effective Time to read: “The name of the corporation is Asterias Biotherapeutics, Inc.” At the Effective Time and subject to Section 6.4, the bylaws of Merger Sub, as in effect immediately prior to the Effective Time, will be the bylaws of the Surviving Corporation until thereafter amended as provided by such bylaws, the certificate of incorporation of the Surviving Corporation or the DGCL.

Section 1.5 Directors and Officers of the Surviving Corporation. The directors of Merger Sub immediately prior to the Effective Time shall be the directors of the Surviving Corporation, serving until the earlier of their resignation or removal or until their respective successors are duly elected and qualified, as the case may be. The officers of Merger Sub immediately prior to the Effective Time shall be the officers of the Surviving Corporation, serving until the earlier of their resignation or removal or until their respective successors are duly elected and qualified, as the case may be.

2

Section 1.6 Post-Merger Operations. The Parties shall use commercially reasonable efforts to ensure that effective immediately following the Effective Time, the BioTime Board of Directors shall consist of the members listed on Schedule 1.6 (unless otherwise agreed between the parties in writing prior to the Effective Time), each hold office from and after the Effective Time until the earliest of appointment of his or her respective successor, resignation or proper removal.

Article II

Effects on Capital Stock; Exchange of Securities

Section 2.1 Effects on Capital Stock.

(a) Conversion of Asterias Common Stock. At the Effective Time, by virtue of the Merger and without any action on the part of the Parties or holders of any securities of Asterias or of Merger Sub, subject to Section 2.1(c), Section 2.5 and Section 2.6, each share of Asterias Common Stock that is issued and outstanding immediately prior to the Effective Time (other than shares of Asterias Common Stock to be cancelled in accordance with Section 2.1(b)) will be automatically converted into the right to receive that number of fully paid and nonassessable BioTime Common Shares equal to the Exchange Ratio (the “Per Share Merger Consideration”). From and after the Effective Time, all such shares of Asterias Common Stock will no longer be outstanding and will automatically be cancelled and will cease to exist, and each applicable holder of such shares of Asterias Common Stock will cease to have any rights with respect thereto, except the right to receive, upon the surrender of such shares of Asterias Common Stock in accordance with ‎Section 2.2, the Per Share Merger Consideration and cash in lieu of any fractional BioTime Common Shares pursuant to ‎Section 2.6 (the “Fractional Share Consideration”) into which such shares of Asterias Common Stock have been converted pursuant to this Section 2.1(a), together with the amounts, if any, payable pursuant to Section 2.2(g).

(b) Cancellation of Asterias Common Stock. At the Effective Time, all shares of Asterias Common Stock owned by BioTime, Asterias or any of their respective wholly owned Subsidiaries will be cancelled and will cease to exist, and no consideration will be delivered in exchange therefor.

(c) Adjustment. The Exchange Ratio and the Fractional Share Consideration and any other similarly dependent items, as the case may be, will be adjusted appropriately to reflect the effect of any stock split, reverse stock split, stock dividend (including any dividend or distribution of securities convertible into shares of Asterias Common Stock or BioTime Common Shares, as applicable), reorganization, recapitalization, reclassification, combination, exchange of shares or other like change with respect to the number of shares of Asterias Common Stock or BioTime Common Shares outstanding after the date hereof and prior to the Effective Time in order to provide the holders of Asterias Common Stock the same economic effect as contemplated by this Agreement prior to such event.

3

Section 2.2 Payment for Securities; Surrender of Certificates.

(a) Exchange Fund. Prior to the Effective Time, BioTime will designate American Stock Transfer & Trust Company, LLC to act as the exchange agent in connection with the Merger (the “Exchange Agent”). The Exchange Agent will also act as the agent for Asterias’ stockholders for the purpose of receiving and holding their Certificates and Book-Entry Shares and will obtain no rights or interests in the shares represented thereby. At or promptly after the Effective Time, BioTime will deposit, or cause to be deposited, with the Exchange Agent (i) a sufficient number of BioTime Common Shares (whether represented in certificated or non-certificated direct registration form) to issue the aggregate Per Share Merger Consideration and (ii) cash sufficient to make payments of Fractional Share Consideration and any dividends under Section 2.2(g) to be paid in the Merger. All such cash and BioTime Common Shares that are deposited with the Exchange Agent are referred to as the “Exchange Fund.” The Exchange Fund will be for the sole benefit of the holders of shares of Asterias Common Stock. BioTime will cause the Exchange Agent to make, and the Exchange Agent will make, delivery of the Merger Consideration out of the Exchange Fund in accordance with this Agreement. The Exchange Fund will not be used for any purpose that is not expressly provided for in this Agreement.

(b) Procedures for Surrender of Book Entry Shares. At the Effective Time and without any action on the part of any holder, all non-certificated shares of Asterias Common Stock represented by book-entry (“Book-Entry Shares”) shall be deemed surrendered to the Exchange Agent, and BioTime shall cause the Exchange Agent to (i) deliver to each holder of Book-Entry Shares that number of uncertificated whole BioTime Common Shares that the holder is entitled to receive pursuant to Section 2.1 and cancel such Book-Entry Shares and (ii) mail to each holder of Book-Entry Shares a check in the amount of any Fractional Share Consideration, and any dividends or other distributions on BioTime Common Shares in accordance with Section 2.2(g), in each case payable in respect of such holder Book-Entry Shares pursuant to Section 2.1.

4

(c) Procedures for Surrender of Certificates. Promptly after the Effective Time, BioTime will, and will cause the Surviving Corporation to, cause the Exchange Agent to mail to each holder of record of a certificate or certificates that immediately prior to the Effective Time represented outstanding shares of Asterias Common Stock (the “Certificates”) and whose shares of Asterias Common Stock were converted pursuant to Section 2.1 into the right to receive the Per Share Merger Consideration (1) a letter of transmittal, which will specify that delivery will be effected, and risk of loss and title to the Certificates will pass, only upon delivery of the Certificates (or affidavits of loss in lieu thereof) to the Exchange Agent and will be in such form and have such other provisions as BioTime may reasonably specify and (2) instructions for effecting the surrender of the Certificates (or affidavits of loss in lieu thereof) in exchange for payment of the Per Share Merger Consideration into which such shares of Asterias Common Stock have been converted pursuant to Section 2.1, including any Fractional Share Consideration payable in accordance with ‎Section 2.6, and any dividends or other distributions on BioTime Common Shares in accordance with Section 2.2(g). Upon surrender of a Certificate (or an affidavit of loss in lieu thereof) for cancellation to the Exchange Agent or to such other agent or agents as may be appointed by BioTime or the Surviving Corporation, together with such letter of transmittal duly completed and validly executed in accordance with the instructions thereto, and such other documents as may be reasonably required pursuant to such instructions, the holder of such Certificate will be entitled to receive in exchange therefor the applicable Merger Consideration pursuant to the provisions of this Article II for each share of Asterias Common Stock formerly represented by such Certificate, to be mailed within ten (10) business days following the later to occur of (x) the Effective Time or (y) the Exchange Agent’s receipt of such Certificate (or affidavit of loss in lieu thereof), and the Certificate (or affidavit of loss in lieu thereof) so surrendered will be forthwith cancelled. The Exchange Agent will accept such Certificates (or affidavits of loss in lieu thereof) upon compliance with such reasonable terms and conditions as the Exchange Agent may impose to effect an orderly exchange thereof in accordance with normal exchange practices. If payment of the Merger Consideration is to be made to a Person other than the Person in whose name the surrendered Certificate is registered, it will be a condition precedent of payment that (A) the Certificate so surrendered will be properly endorsed or will be otherwise in proper form for transfer and (B) the Person requesting such payment has paid any transfer and other similar Taxes required by reason of the payment of the Merger Consideration to a Person other than the registered holder of the Certificate surrendered or has established to the satisfaction of the Surviving Corporation that such Tax either has been paid or is not required to be paid. Until surrendered as contemplated by this Section 2.2, each Certificate will be deemed at any time after the Effective Time to represent only the right to receive the applicable Merger Consideration as contemplated by this Article II, without interest thereon.

(d) Transfer Books; No Further Ownership Rights in Shares of Asterias Common Stock. At the Effective Time, the stock transfer books of Asterias will be closed and thereafter there will be no further registration of transfers of shares of Asterias Common Stock on the records of Asterias. From and after the Effective Time, the holders of Certificates and Book-Entry Shares outstanding immediately prior to the Effective Time will cease to have any rights with respect to such shares of Asterias Common Stock except as otherwise provided for herein or by applicable Law. If, after the Effective Time, Certificates or Book-Entry Shares are presented to the Surviving Corporation for any reason, they will be cancelled and exchanged as provided in this Agreement.

(e) Termination of Exchange Fund; No Liability. At any time following the first anniversary of the Effective Time, BioTime will be entitled to require the Exchange Agent to deliver to it any funds (including any interest received with respect thereto) remaining in the Exchange Fund that have not been disbursed, or for which disbursement is pending subject only to the Exchange Agent’s routine administrative procedures, to holders of Certificates, and thereafter such holders (as well as any holders of Book-Entry Shares who have not theretofore cashed any check payable to them in accordance with Section 2.2(b)) will be entitled to look only to the Surviving Corporation and BioTime (subject to abandoned property, escheat or other similar Laws) as general creditors thereof with respect to the applicable Merger Consideration, payable upon due surrender of their Certificates and compliance with the procedures in Section 2.2(b) and Section 2.2(c), without any interest thereon. Notwithstanding the foregoing, none of the Surviving Corporation, BioTime, Merger Sub or the Exchange Agent will be liable to any holder of a Certificate for any Merger Consideration, dividends, or other amounts delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law.

5

(f) Lost, Stolen or Destroyed Certificates. In the event that any Certificates have been lost, stolen or destroyed, the Exchange Agent will issue in exchange for such lost, stolen or destroyed Certificates, upon the making of an affidavit of that fact by the holder thereof (such affidavit to be in a form reasonably satisfactory to BioTime and the Exchange Agent), the Merger Consideration payable in respect thereof and any dividends or other distributions on BioTime Common Shares in accordance with Section 2.2(g).

(g) Dividends or Distributions with Respect to BioTime Common Shares. No dividends or other distributions with respect to BioTime Common Shares with a record date after the Effective Time will be paid to the holder of any unsurrendered Certificate or Book-Entry Share with respect to the BioTime Common Shares represented thereby, and all such dividends and other distributions will be paid by BioTime to the Exchange Agent and will be included in the Exchange Fund, in each case until the surrender of such Certificate or Book-Entry Share (or affidavit of loss in lieu thereof) in accordance with this Agreement. Subject to applicable Laws, following surrender of any such Certificate or Book-Entry Share (or affidavit of loss in lieu thereof) there will be paid to the holder thereof, without interest, (1) promptly, the amount of dividends or other distributions with a record date after the Effective Time theretofore paid with respect to such BioTime Common Shares to which such holder is entitled pursuant to this Agreement and (2) at the appropriate payment date, the amount of dividends or other distributions with a record date after the Effective Time but prior to such surrender and with a payment date subsequent to such surrender payable with respect to such BioTime Common Shares.

Section 2.3 Treatment of Asterias Equity Awards.

(a) No Asterias Equity Awards shall be assumed or continued by BioTime in connection with the Merger or the other Transactions.

(b) Upon the terms and subject to the conditions set forth in this Agreement, at the Effective Time, by virtue of the Merger and without any action on the part of BioTime, Merger Sub, Asterias, or the holders or recipients of Asterias Stock Options, each Asterias Stock Option that is outstanding immediately prior to the Effective Time shall be cancelled and extinguished for no consideration and shall cease to exist.

(c) Upon the terms and subject to the conditions set forth in this Agreement, immediately prior to the Effective Time, by virtue of the Merger and without any action on the part of BioTime, Merger Sub, Asterias, or the holders or recipients of Asterias RSU Awards, (i) each Asterias RSU Award that is held by any Worker and is outstanding as of immediately prior to the Effective Time shall vest in full and (ii) each Asterias RSU Award shall be cancelled and converted automatically into the right to receive, as soon as reasonably practicable after the Effective Time (but no later than five (5) business days thereafter), the Merger Consideration in respect of each share of Asterias Common Stock underlying the vested portion of the Asterias RSU Award.

(d) Prior to the Effective Time, and subject to the prior review and approval of BioTime, Asterias shall take all actions necessary to effect the transactions anticipated by this Section 2.3 under the Asterias Equity Plan and any Contract applicable to any Asterias Equity Awards (whether written or oral, formal or informal), including delivering all required notices, obtaining all necessary approvals and consents, and delivering evidence satisfactory to BioTime that all necessary determinations by Asterias Board of Directors or applicable committee thereof to cancel all Asterias Equity Awards in accordance with this Section 2.3 have been made. At the Effective Time, BioTime shall assume sponsorship of the Asterias Equity Plan, provided that references to Asterias in the Asterias Equity Plan and award agreements for the Asterias Equity Awards shall thereupon be deemed references to BioTime and references to shares therein shall be deemed references to BioTime Common Shares with appropriate equitable adjustments to reflect the Transactions.

6

Section 2.4 Treatment of Warrants. Prior to the Effective Time, Asterias shall take any necessary actions in accordance with the terms of the Asterias Warrants, including the giving of any notices that may be required as a result of the Transactions constituting a “Fundamental Transaction” as such terms are defined in the Asterias Warrants. Asterias and BioTime shall take all actions as may be necessary to ensure that the Asterias Warrants are treated in accordance with Section 4(b) of the Asterias Warrants.

Section 2.5 Withholding. Notwithstanding any other provision of this Agreement, each of BioTime, Merger Sub, the Surviving Corporation, and the Exchange Agent will be entitled to deduct and withhold from the consideration otherwise payable to a holder of shares of Asterias Common Stock and Asterias Equity Awards pursuant to this Agreement, any amounts as are required to be withheld or deducted with respect to such consideration under the Code, or any applicable provisions of state, local or non-U.S. Tax Law unless such Person receives the requisite certification or documents to eliminate such withholding obligation. To the extent that amounts are so withheld and remitted to the appropriate Governmental Authority, such withheld amounts will be treated for all purposes of this Agreement as having been paid to the holder of shares of Asterias Common Stock and Asterias Equity Awards (to the extent applicable) in respect of which such deduction and withholding was made.

Section 2.6 Fractional Shares.

(a) No certificates, receipts or scrip representing fractional BioTime Common Shares will be issued upon the surrender or transfer for exchange of Certificates or Book-Entry Shares, no dividend or distribution of BioTime will relate to such fractional BioTime Common Shares, and such fractional BioTime Common Shares will not entitle the owner thereof to vote or to any rights of a stockholder of BioTime.

(b) BioTime shall pay to the Exchange Agent an amount in cash in United States dollars, to be deposited promptly following the Effective Time, sufficient for the Exchange Agent to pay each holder of Certificates or Book-Entry Shares an amount in cash equal to the product obtained by multiplying (1) the fraction of a BioTime Common Share to which such holder would otherwise have been entitled by (2) the closing price for a BioTime Common Share on NYSE American on the last complete trading day immediately prior to the Effective Time.

47

(b) Notwithstanding anything to the contrary set forth in this Agreement, the Asterias Board of Directors may (x) effect an Asterias Board Recommendation Change or (y) terminate this Agreement pursuant to Section 8.1(i) to enter into a definitive agreement to consummate a Superior Proposal, in each case at any time prior to obtaining the Asterias Stockholder Approval in the event that

No investigation by BioTime or Asterias or their respective Representatives or information provided, made available or delivered pursuant to this Agreement shall affect the representations, warranties, covenants or agreements of Asterias or BioTime set forth herein.

54

(b) In furtherance and not in limitation of Section 6.2, each of BioTime and Asterias will use its reasonable best efforts to obtain the expiration or termination of all waiting periods and all consents, waivers, authorizations and approvals of all Third Parties, including Governmental Authorities, necessary, proper or advisable for the consummation of the Transactions and to provide any notices to Third Parties required to be provided by them prior to the Effective Time; provided that without consulting with BioTime, Asterias will not incur any expense or liability, enter into any new commitment or agreement or agree to any modification to any contractual arrangement to obtain such consents or certificates. Without limiting the foregoing, each of BioTime and Asterias shall (i) each use its reasonable best efforts to avoid the entry of, or to have vacated or terminated, any decree, Order, or judgment that would restrain, prevent or delay the Closing, on or before the Outside Date, including without limitation defending through litigation on the merits any Claim or Action asserted in any court by any Person and (ii) each use its reasonable best efforts to avoid or eliminate each and every impediment under any antitrust, competition or trade regulation Law that may be asserted by any Governmental Authority with respect to the Merger so as to enable the Closing to occur as soon as reasonably possible (and in any event no later than the Outside Date). Notwithstanding any provision of this Agreement to the contrary, in no event shall Merger Sub or BioTime be required to offer, accept or agree to, and Asterias shall not, without BioTime’s prior written consent, offer, accept or agree to (1) divest, license, dispose of or hold separate any portion of the businesses, operations, assets or product lines of BioTime, Asterias or any of their respective affiliates (or a combination of the respective businesses, operations, assets or product lines of BioTime, Asterias or any of their respective affiliates), (ii) restrict, prohibit or limit the ability of BioTime, Asterias or any of their respective affiliates to conduct its business or own its assets, (iii) restrain, prohibit or limit the ownership or operation by BioTime, Asterias or any of their respective affiliates of all or any portion of the business or assets of BioTime, Asterias or any of their respective affiliates in any part of the world, (iv) cause BioTime or any of its affiliates to divest any shares of the capital stock of the Surviving Corporation or (v) impose limitations on the ability of BioTime or any of its affiliates effectively to acquire, hold or exercise full rights of ownership of, any shares of capital stock of the Surviving Corporation, including the right to vote any shares of capital stock of the Surviving Corporation acquired or owned by BioTime or any of its affiliates on all matters properly presented to the stockholders of Asterias.

Without limiting the foregoing, BioTime and Asterias shall use reasonable efforts to cooperate to develop all public announcement materials and make appropriate management available at presentations related to the Transactions as reasonably requested by the other Party.

For not less than six (6) years from and after the Effective Time, the Surviving Corporation will, and BioTime will cause the Surviving Corporation to, indemnify and hold harmless all past and present directors, officers and employees of Asterias (collectively, the “Indemnified Parties”) against any costs or expenses (including advancing attorneys’ fees and expenses in advance of the final disposition of any actual or threatened Claim, Action, investigation, suit or proceeding, whether civil, criminal, administrative or investigative, to each Indemnified Party to the fullest extent permitted by Law, as long as such Indemnified Party agrees in advance to return any such funds to which a court of competent jurisdiction has determined in a final, nonappealable judgment such Indemnified Party is not ultimately entitled), judgments, fines, losses, Claims, damages, liabilities and amounts paid in settlement in connection with any actual or threatened Claim, Action, investigation, suit or proceeding in respect of acts or omissions occurring or alleged to have occurred at or prior to the Effective Time (including acts or omissions occurring in connection with the approval of this Agreement and the consummation of the Merger or any of the other Transactions), whether asserted or claimed prior to, at or after the Effective Time, in connection with such Persons serving as an officer, director, employee or other fiduciary of Asterias or of any Person if such service was at the request or for the benefit of Asterias, to the fullest extent permitted by Law or provided pursuant to the Asterias Governing Documents or any indemnification agreements, if any, in existence on the date of this Agreement. All rights to elimination of liability, indemnification and advancement of expenses for acts or omissions occurring or alleged to have occurred at or prior to the Effective Time, whether asserted or claimed prior to, at or after the Effective Time, now existing in favor of the Indemnified Parties as provided in their respective certificate of incorporation or by-laws (or comparable organizational documents) or in any agreement will survive the Merger and will continue in full force and effect. For six (6) years after the Effective Time, the Surviving Corporation will cause to be maintained in effect the provisions in (1) the Asterias Governing Documents and (2) any other agreements of Asterias with any Indemnified Party, in each case, regarding elimination of liability, indemnification of officers, directors and employees and advancement of expenses that are in existence on the date of this Agreement, and no such provision will be amended, modified or repealed in any manner that would adversely affect the rights or protections thereunder of any such Indemnified Party in respect of acts or omissions occurring or alleged to have occurred at or prior to the Effective Time (including acts or omissions occurring in connection with the approval of this Agreement and the consummation of the Merger or any of the other Transactions). BioTime will cause the Surviving Corporation to provide, for an aggregate period of not less than six (6) years from the Effective Time, Asterias’ current directors and officers an insurance and indemnification policy that provides coverage for events occurring prior to the Effective Time (the “D&O Insurance”) that is no less favorable than Asterias’ existing policy or, if insurance coverage that is no less favorable is unavailable, the best available coverage; provided however that the Surviving Corporation will not be required to pay an annual premium for the D&O Insurance in excess of 300% of the last annual premium paid prior to the date of this Agreement; provided further that Asterias may prior to the Effective Time substitute therefor a single premium tail coverage with respect to D&O Insurance with an annual cost not in excess of 300% of the last annual premium paid prior to the date of this Agreement. Notwithstanding anything herein to the contrary, if any Indemnified Party notifies BioTime on or prior to the sixth (6^th) anniversary of the Effective Time of a matter in respect of which such Person may seek indemnification pursuant to this Section 6.4, the provisions of this Section 6.4 will continue in effect with respect to such matter until the final disposition of all Claims and Actions relating thereto. In the event BioTime or the Surviving Corporation or any of their respective successors or assigns (1) consolidates with or merges into any other Person and will not be the continuing or surviving corporation or entity of such consolidation or merger or (2) transfers all or substantially all of its properties and assets to any Person, then, and in each such case, proper provision will be made so that the successors and assigns of BioTime or the Surviving Corporation, as the case may be, will assume the obligations set forth in this Section 6.4. The rights and obligations under this Section 6.4 will survive consummation of the Merger and will not be terminated or amended in a manner that is adverse to any Indemnified Party without the written consent of such Indemnified Party. The provisions of this Section 6.4 are intended to be for the benefit of, and shall be enforceable by, each Indemnified Party, his or her heirs and his or her Representatives. The indemnification and advancement provided for in this Section 6.4 is not exclusive of any other rights to which the Indemnified Party is entitled whether pursuant to Law, contract, or otherwise.

Section 6.5 Takeover Statutes. The Parties will use their respective reasonable best efforts (a) to take all action necessary so that no Takeover Statute is or becomes applicable to the Merger or any of the other Transactions and (b) if any such Takeover Statute is or becomes applicable to any of the foregoing, to take all action necessary so that the Merger and the other Transactions may be consummated as promptly as practicable on the terms contemplated by this Agreement and otherwise to eliminate or minimize the effect of such Takeover Statute on the Merger and the other Transactions.

Section 6.6 Obligations of Merger Sub. BioTime will take all action necessary to cause each of Merger Sub and the Surviving Corporation to perform their respective obligations under this Agreement before and after the Effective Time and to consummate the Transactions, including the Merger, upon the terms and subject to the conditions set forth in this Agreement.

If requested by BioTime at least five (5) business days prior to the Closing, then effective as of no later than the day immediately preceding the Closing, Asterias will terminate each Asterias Plan intended to be “qualified” within the meaning of Section 401(a) of the Code.

Section 6.8 Rule 16b-3. Prior to the Effective Time, BioTime and Asterias shall take all such steps as may be required to cause any acquisitions or dispositions of Asterias Common Stock (including derivative securities with respect to Asterias Common Stock) or acquisitions of BioTime Common Shares (including derivative securities with respect to BioTime Common Shares) resulting from the Transactions by each individual who is subject to the reporting requirements of Section 16(a) of the Exchange Act with respect to Asterias or will become subject to such reporting requirements with respect to BioTime, to be exempt under Rule 16b-3 promulgated under the Exchange Act, to the extent permitted by applicable Law.

Section 6.9 Security Holder Litigation. Each Party will provide the other Party prompt notice of any litigation brought by any stockholder of that Party against such Party, any of its Subsidiaries and/or any of their respective directors relating to the Merger, this Agreement or any of the Transactions, and will provide the other Party with updates and such information as such other Party will reasonably request with respect to the status of the litigation and discussions between the parties to such litigation (unless the provision of such updates and information could reasonably be expected to result in a loss of attorney-client privilege). Asterias will give BioTime the opportunity to participate in the defense of and settlement discussions with respect to any such litigation and will not settle or make any payment or settlement offer with respect to any such litigation unless BioTime has consented in writing to such payment or settlement, which consent will not be unreasonably withheld, conditioned or delayed. In the event of, and to the extent of, any conflict or overlap between the provisions of this Section 6.9 and Section 5.1 or Section 5.2, the provisions of this Section 6.9 will control.

Section 6.10 Delisting. Each of the Parties agrees to cooperate with the other Parties in taking, or causing to be taken, all actions necessary to delist Asterias Common Stock from NYSE American and terminate its registration under the Exchange Act, provided that such delisting and termination will not be effective until after the Effective Time.

Section 6.13 Qualification as a Reorganization. The Merger is intended to qualify as a “reorganization” within the meaning of Section 368(a) of the Code, and this Agreement is intended to constitute a “plan of reorganization” within the meaning of Treasury Regulations Sections 1.368-2(g) and 1.368-3. From and after the date of this Agreement, each Party shall use its best efforts to cause the Merger to qualify as a reorganization under Section 368(a) of the Code. BioTime, Merger Sub and Asterias will not take or cause to be taken any action that, either alone or in combination, could reasonably be expected to cause the Merger to fail to qualify as a “reorganization” within the meaning of Section 368(a) of the Code. BioTime and its affiliates (including the Surviving Corporation) will use commercially reasonable efforts to continue the historic business of Asterias (or alternatively, if Asterias has more than one line of business, continue at least one significant line of Asterias’ historic business) or use a significant portion (at least 33-1/3% by value) of Asterias’ historic business assets in a business within the meaning of Treasury Regulations Section 1.368-1(d). The Parties will take the position for all Tax purposes that the Merger qualifies as a reorganization within the meaning of Section 368(a) of the Code, unless a contrary position is required by a taxing authority in connection with a good faith resolution of a Tax contest. Asterias will use reasonable best efforts to obtain a Tax opinion satisfying the requirements of Item 601 of Regulation S-K under the Securities Act. Officers of each of Asterias and BioTime will deliver to Dentons LLP, counsel to Asterias, a customary representation letter for purposes of such Tax opinion, at such time or times as may be reasonably requested by Dentons LLP, including the effective date of the Registration Statement and the Closing Date.

Asterias shall furnish BioTime as promptly as practicable following BioTime’s request, such information regarding Asterias as is customarily required in connection with the Merger including (a) financial statements that have been prepared in conformity with GAAP, (b) such other financial, business and other information regarding the Asterias as BioTime shall request from the Asterias, that BioTime may be required to file with the SEC in connection with the approval of this Agreement and the consummation of the Merger or any of the other Transactions.

Section 6.15 Notification of Certain Matters Asterias and BioTime shall promptly notify each other of the discovery of any fact or circumstance that, or the occurrence or non-occurrence of any event the occurrence or non-occurrence of which would reasonably be expected to result in any of the conditions to the Merger set forth in Article VII not being satisfied or satisfaction of those conditions being materially delayed in violation of any provision of this Agreement; provided, however, that the delivery of any notice pursuant to this Section 6.15 shall not (x) cure any breach of, or non-compliance with, any other provision of this Agreement or (y) limit the remedies available to the party receiving such notice; provided further, that unintentional failure to give prompt notice pursuant to this clause shall not constitute a failure of a condition to the Merger set forth in Article VII except to the extent that the underlying fact or circumstance not so notified would standing alone constitute such a failure.

Section 6.16 Employee and Labor Matters.

(a) For a period commencing on the Effective Time, and ending on December 31, 2019, the Surviving Corporation will provide individuals who are employees of Asterias immediately prior to the Effective Time and continue to be employees of BioTime or one of the BioTime Subsidiaries (including the Surviving Corporation) immediately following the Effective Time, but only for so long as such individuals are so employed (each, a “Continuing Employee”), employee benefits (other than equity-based awards) that are either (A) substantially comparable to the employee benefits (other than equity-based awards) provided by Asterias on the date of this Agreement or (B) substantially comparable to the employee benefits (other than equity-based awards) provided to similarly-situated employees of BioTime.

58

(b) As of the Effective Time, BioTime shall, and shall cause the Surviving Corporation to, use commercially reasonable efforts to give Continuing Employees credit for purposes of eligibility, benefit accrual, vesting and entitlement to benefits where length of service is relevant (but not for any purposes under any employee benefit plan that is a defined benefit pension plan or with respect to an equity plan) under any applicable BioTime Plans that such employees may be eligible to participate in after the Effective Time (“New Plans”) for such Continuing Employees’ service with Asterias to the same extent that such service was credited for purposes of any comparable employee benefit plan of Asterias immediately prior to the Effective Time and in no event shall service prior to the Effective Time be required to be taken into account if such service credit would result in the duplication of benefits with respect to the same period or if such service credit would violate the terms of any New Plan. In addition, and without limiting the generality of the foregoing, BioTime shall use commercially reasonable efforts to provide that (1) each Continuing Employee shall be immediately eligible to participate, without any waiting time, in any and all New Plans to the extent coverage under such New Plan replaces coverage under a comparable Asterias Plan in which such Continuing Employee participated immediately before the replacement, and (2) for purposes of each New Plan providing medical, dental, pharmaceutical and/or vision benefits to any Continuing Employee, all pre-existing condition limitations, exclusions, actively-at-work requirements or waiting periods of such New Plan be waived for such employee and his or her covered dependents to the extent waived or not applicable under a comparable Asterias Plan in which such Continuing Employee participated immediately before the replacement, and any eligible expenses incurred by such employee and his or her covered dependents under a Asterias Plan during the portion of the plan year prior to the Effective Time to taken into account under such New Plan for purposes of satisfying all deductible, co-insurance, co-payment and maximum out-of-pocket requirements applicable to such employee and his or her covered dependents for the remainder of the applicable plan year during which the Effective Time occurs as if such amounts had been paid in accordance with such New Plan, in each case subject to the terms and conditions of each New Plan.

(c) From and after the Effective Time, Asterias or the Surviving Corporation, as applicable, will, and BioTime will cause Asterias or the Surviving Corporation, as applicable, to, honor, in accordance with their terms, all employment, severance, income continuity and change of control programs, plans or agreements between Asterias and its employees including bonuses, incentives, severance payments or deferred compensation that are listed on Section 6.16(c) of the Asterias Disclosure Letter (which disclosure shall include the amount payable under any such programs, plans or arrangements), in each case, in accordance with their terms as of the date of this Agreement.

(d) No provision of this Section 6.16 shall be construed as a limitation on the right of BioTime, or to cause any BioTime Subsidiary to, amend or terminate any specific employee benefit plan that BioTime or a BioTime Subsidiary would otherwise have under the terms of such employee benefit plan, nor shall any provision of this Section 6.16 be construed to require the continuation of the employment of any particular Continuing Employee. The provisions of this Section 6.16 are solely for the benefit of the Parties, and no Person shall be a third-party beneficiary of this Section 6.16, and nothing herein shall be construed as an amendment to any employee benefit plan of BioTime or any BioTime Subsidiary or other compensation or benefit plan or arrangement for any purpose.
