1.3 Bylaws. The Bylaws of LifeMap existing on the Effective Date shall continue in full force as the Bylaws of the surviving corporation until altered, amended, or repealed as provided in such Bylaws or by law.

1.4 Merger Consideration.

(a) Upon the consummation of the Merger, the outstanding shares of Xennex capital stock, shall automatically and by operation of the Merger be converted into BioTime Shares and LifeMap Shares as follows (the Merger Consideration):

(b) The total number of BioTime Shares to be issued to Xennex Stockholders as part of the Merger Consideration, shall be determined by dividing $2,000,000 by $4.46 per share which is the weighted average closing price of BioTime Shares as reported on the NYSE Amex for the twenty (20) trading days ending on and including the third trading day immediately preceding the date of this Agreement. The total number of LifeMap Shares to be issued to Xennex Stockholders as part of the Merger Consideration shall be determined by dividing $2,384,530 by $1.75, which the Parties agree is the fair market value of one LifeMap Share (as adjusted for the one-for-four reverse stock split to be effected concurrent with the filing of the California Merger Certificate. Accordingly, the number of BioTime Shares to be issued to Xennex Stockholders, collectively, as part of the Merger Consideration shall be 448,430 BioTime Shares; and the number of LifeMap Shares to be issued to Xennex Stockholders as the remainder of the Merger Consideration, shall be 1,362,589 LifeMap Shares.

(i) Based on the forgoing, and Assuming that no additional shares of Xennex common stock, no par value per share (Xennex Stock), are issued and no shares of Xennex Stock are redeemed or reacquired by Xennex, upon the consummation of the Merger, each outstanding share of Xennex Stock, shall be converted into 448.43 BioTime Shares and 1,362.589 LifeMap Shares or the right to receive cash in lieu of any fractional share as provided in Section 1.4(c).

(ii) Notwithstanding the foregoing, the BioTime Shares and LifeMap Shares comprising Escrow Shares within the context of Section 1.7 shall be issued or issuable in the Merger in the name of the Representative for the benefit of the Xennex Stockholders holders as their interests may appear and subject to the terms of this Agreement and the Escrow Agreement (as defined below), including the terms hereof appointing and empowering (and limiting the liability) of the Representative, and all rights of the Xennex Stockholders in respect thereof shall be and are therefore expressly limited accordingly.

In determining the number of BioTime Shares and LifeMap Shares to be issued to a Xennex Stockholder in the Merger, any fractional BioTime Shares or fractional LifeMap Shares that would otherwise be issuable with respect to the Xennex Shares registered in the name of that Xennex Stockholder shall be aggregated into the greatest number of whole BioTime Shares and whole LifeMap Shares as is feasible in each case. In lieu of issuing any fractional BioTime Share remaining after the aforesaid aggregation of fractions, BioTime shall pay the Xennex Stockholder cash in an amount determined by multiplying the remaining aggregate fraction by the average closing price of a BioTime Share as reported on the NYSE Amex for the twenty (20) trading days immediately preceding the Closing Date. In lieu of issuing any fractional LifeMap Share remaining after the aforesaid aggregation of fractions, LifeMap shall pay the Xennex Stockholder cash in an amount determined by multiplying the remaining aggregate fraction by $1.75.

(d) As soon as reasonably practicable after the Effective Date, BioTime and LifeMap will mail to each Xennex Stockholder, whose Xennex Shares were converted into the right to receive BioTime Shares and LifeMap Shares, a letter of transmittal and instructions for use in delivering Xennex Share certificates in exchange for certificates representing the BioTime Shares and LifeMap Shares into which the Xennex Stockholder’s Xennex Shares were converted in the Merger and cash for in lieu of fractional BioTime Shares and fractional LifeMap Shares, less the Xennex Stockholder’s pro rata share of the BioTime Shares and LifeMap Shares held in the Escrow.

1.8 Indemnification by Xennex.

Subject to this Section 1.8, Section 1.9, and Section 1.11., from and after the Closing, the Xennex Stockholders, severally but not jointly, shall be deemed to have agreed to indemnify, defend, and hold harmless LifeMap and BioTime from and against any liability, damage, loss, cost, or expense, including reasonable attorneys' fees and expenses (Losses) which LifeMap or BioTime may sustain as a result of a breach or breaches of the Article 2 Warranties.

To the extent that LifeMap or BioTime incurs any Loss as a result of any breach of any of the Article 2 Warranties, the Merger Consideration shall be deemed reduced by the amount of such Loss, and such reduction shall be applied to the Escrow Shares, by return of such number of Escrow Shares by Escrow Agent to BioTime and LifeMap, as may be computed in accordance with this Section 1.9. The number of the Escrow Shares to be returned to BioTime from the escrow with respect to any Loss shall be the amount of the Loss multiplied by 0.4561 and divided by the then applicable value of each BioTime Share (the BioTime Escrow Share Value). The value of each BioTime Share shall be the average closing price of the BioTime Shares on the NYSE Amex (or on such other exchange or over the counter market on which the BioTime Shares may trade if they are then no longer traded on the NYSE Amex) during twenty (20) trading days immediately prior to the date of the written request signed by each of the Parties for release of such BioTime Escrow Shares from escrow. The number of the Escrow Shares to be returned to LifeMap from the escrow with respect to any Loss shall be the amount of the Loss multiplied by 0.5439 and divided by $1.75 (the agreed value of each LifeMap Share) (the LifeMap Escrow Share Value). If as a result of any Loss the number of BioTime Escrow Shares is reduced to zero while LifeMap Escrow Shares remain in Escrow, or if the number of LifeMap Escrow Shares is reduced to zero while BioTime Escrow Shares remain in escrow, any subsequent reduction in the Escrow Consideration on account of any Loss shall be applied to the Escrow Shares remaining in escrow. The Escrow Agent shall deliver the BioTime Escrow Shares to BioTime or the transfer agent of such shares, and shall deliver the LifeMap Escrow Shares to LifeMap on account of any Loss within 10 days after receipt of a written request for delivery signed by each of the Parties stating the amount of the Loss and the number of BioTime Escrow Shares and LifeMap Escrow Shares to be returned to BioTime and LifeMap. If the Escrow Agent receives any money as a dividend or distribution with respect to Escrow Shares, or as consideration of any merger or consolidation or BioTime or LifeMap with another business entity, such money shall be applied on account of any Loss before Escrow Shares.

1.10 Indemnification by BioTime and LifeMap.

Agreement of Merger

This Agreement of Merger is entered into between LifeMap Sciences, Inc., a California corporation (herein “Surviving Corporation”), Xennex, Inc., a Massachusetts corporation (herein “Xennex” or “Merging Corporation”), and BioTime, Inc., a California corporation (herein “BioTime” or “Parent Corporation”).

1. The Merging Corporation shall be merged into the Surviving Corporation (the “Merger”).

2. Upon the consummation of the Merger, the outstanding shares of Xennex common stock shall automatically and by operation of the Merger be converted into shares of Surviving Corporation common stock, no par value (“LifeMap Shares”) and BioTime common shares, no par value (“BioTime Shares”) as follows (the “Merger Consideration”):

(a) The total number of BioTime Shares to be issued to Xennex Stockholders as part of the Merger Consideration, shall be determined by dividing $2,000,000 by $4.46 per share which is the weighted average closing price of BioTime Shares as reported on the NYSE Amex for the twenty (20) trading days ending on and including the third trading day immediately preceding the date of this Agreement. The total number of LifeMap Shares to be issued to Xennex Stockholders as part of the Merger Consideration shall be determined by dividing $2,384,530 by $1.75, which the Parties agree is the fair market value of one LifeMap Share (as adjusted for the one-for-four reverse stock split to be effected concurrent with the filing of the California Merger Certificate. Accordingly, the number of BioTime Shares to be issued to Xennex Stockholders, collectively, as part of the Merger Consideration shall be 448,430 BioTime Shares; and the number of LifeMap Shares to be issued to Xennex Stockholders as the remainder of the Merger Consideration, shall be 1,362,589 LifeMap Shares.

(b) Each share of Xennex common stock outstanding shall be converted in the Merger into (i) that number of LifeMap Shares determined by dividing (A) the total number of LifeMap Shares to be issued in the Merger by (B) the total number of shares of Xennex common stock issued and outstanding, and (ii) that number of BioTime Shares determined by dividing (A) the total number of BioTime Shares to be issued in the Merger by (B) the total number of shares of Xennex common stock issued and outstanding. Accordingly, the number of BioTime Shares to be issued to Xennex Stockholders, collectively, as part of the Merger Consideration shall be 448,430 BioTime Shares; and the number of LifeMap Shares to be issued to Xennex Stockholders as the remainder of the Merger Consideration, shall be 1,362,589 LifeMap Shares.

(i) Based on the forgoing, and assuming that no additional shares of Xennex common stock, no par value per share (Xennex Stock), are issued and no shares of Xennex Stock are redeemed or reacquired by Xennex, upon the consummation of the Merger, each outstanding share of Xennex Stock, shall be converted into 448.43 BioTime Shares and 1,362.589 LifeMap Shares or the right to receive cash in lieu of any fractional share as provided below.

(ii) LifeMap’s obligation to consummate the Merger is conditioned upon no Xennex stockholder having and electing to demand the appraisal of such Xennex Stockholder’s shares under Massachusetts General Law, Chapter 156B.

3. No fractional BioTime Shares or fractional LifeMap Shares shall be issued in the Merger. In determining the number of BioTime Shares and LifeMap Shares to be issued to a Xennex stockholder in the Merger, any fractional BioTime Shares or fractional LifeMap Shares that would otherwise be issuable with respect to the Xennex common stock registered in the name of that Xennex stockholder shall be aggregated into the greatest number of whole BioTime Shares and whole LifeMap Shares as is feasible in each case. In lieu of issuing any fractional BioTime Share remaining after the aforesaid aggregation of fractions, BioTime shall pay the Xennex Stockholder cash in an amount determined by multiplying the remaining aggregate fraction by the average closing price of a BioTime Share as reported on the NYSE Amex for the twenty (20) trading days immediately preceding the date of consummation of the Merger. In lieu of issuing any fractional LifeMap Share remaining after the aforesaid aggregation of fractions, LifeMap shall pay the Xennex Stockholder cash in an amount determined by multiplying the remaining aggregate fraction by $1.75.

4. The outstanding shares of Surviving Corporation and Parent Corporation shall remain outstanding and are not affected by the Merger.

5. Merging Corporation shall from time to time, as and when requested by Surviving Corporation, execute and deliver all such documents and instruments and take all such action necessary or desirable to evidence or carry out the Merger.

6. The effect of the Merger and the effective date of the Merger are as prescribed by law.

DUTIES OF THE ESCROW AGENT

2.1 Scope of Responsibility. Notwithstanding any provision to the contrary, the Escrow Agent is obligated only to perform the duties specifically set forth in this Escrow Agreement, which shall be deemed purely ministerial in nature.

References in this Escrow Agreement to any other agreement, instrument, or document are for the convenience of the Parties, and the Escrow Agent has no duties or obligations with respect thereto. This Escrow Agreement sets forth all matters pertinent to the Escrow contemplated hereunder, and no additional obligations of the Escrow Agent shall be inferred or implied from the terms of this Escrow Agreement or any other agreement.

2.2 Reliance. The Escrow Agent shall not be liable for any action taken or not taken by it in accordance with the direction or consent of the Parties or their respective agents, representatives, successors, or assigns, but only if such direction or consent is consistent with the terms of this Escrow Agreement.

Article 3

PROVISIONS CONCERNING THE ESCROW AGENT

3.1 Indemnification. The Parties, jointly and severally, shall indemnify, defend and hold harmless the Escrow Agent from and against any and all loss, liability, cost, damage, and expense, including, without limitation, attorneys' fees and expenses or other professional fees and expenses which the Escrow Agent may suffer or incur by reason of any action, claim, or proceeding brought against the Escrow Agent, arising out of or relating in any way to this Escrow Agreement or any transaction to which this Escrow Agreement relates, unless such loss, liability, cost, damage, or expense shall have been finally adjudicated to have been directly caused by the willful misconduct or gross negligence of the Escrow Agent. The provisions of this Section 3.1 shall survive the resignation or removal of the Escrow Agent and the termination of this Escrow Agreement.

3.2 Limitation of Liability. The Escrow Agent shall not be liable, directly or indirectly, for any (i) damages, losses, or expenses arising out of the services provided hereunder, other than damages, losses, or expenses which have been finally adjudicated to have directly resulted from the Escrow Agent's gross negligence or willful misconduct, or (ii) special, indirect, or consequential damages or LOSSES OF ANY KIND WHATSOEVER (INCLUDING WITHOUT LIMITATION LOST PROFITS), even if the Escrow Agent has been advised of the possibility of such LOSSES OR damages AND REGARDLESS OF THE FORM OF ACTION.

3.3 Removal or Resignation.

(a) Removal. The Parties may remove the Escrow Agent by furnishing to the Escrow Agent a joint written notice of its removal along with payment of all fees and expenses to which the Escrow Agent is entitled through the date of termination. Such removal shall be effective thirty (30) days after the delivery of such notice or upon the earlier appointment of a successor escrow agent, and the Escrow Agent's sole responsibility thereafter shall be to safely keep the Escrow Securities and to deliver the same to a successor escrow agent as shall be appointed by the Parties, as evidenced by a joint written notice filed with the Escrow Agent or in accordance with the order of a court or other dispute resolution authority. If the Parties have failed to appoint a successor escrow agent prior to the expiration of thirty (30) days following the delivery of such notice of removal, the Escrow Agent may petition any court of competent jurisdiction for the appointment of a successor escrow agent or for other appropriate relief, and any such resulting appointment shall be binding upon the Parties.

(b) Resignation. If the Escrow Agent shall resign as the escrow agent hereunder, a successor escrow agent shall be promptly appointed jointly by the Parties. The Escrow Agent may resign at any time by giving to the Parties thirty (30) days’ written notice of resignation (the “Resignation Notice”). Such resignation shall take effect when the successor escrow agent accepts in writing its appointment as successor escrow agent and receives the Escrow Securities from the Escrow Agent or, upon disposition of the Escrow Securities, in accordance with written instructions of the Parties. If no successor escrow agent has been appointed and has accepted the Escrow Securities within thirty (30) days after the Resignation Notice is sent, the Escrow Agent may apply to a court of competent jurisdiction for the appointment of a successor escrow agent or for other appropriate relief, and any such resulting appointment shall be binding upon the Parties.

3.4 Compensation. The Escrow Agent shall be entitled to compensation for its services as stated in the fee schedule attached hereto as Exhibit C, which compensation shall be paid by LifeMap. The fee agreed upon for the services rendered hereunder is intended as annual full compensation for the Escrow Agent's services as contemplated by this Escrow Agreement; provided, however, that in the event that Escrow Agent renders any service not contemplated in this Escrow Agreement, or there is any assignment of interest in the subject matter of this Escrow Agreement, or any material modification hereof, or if any material controversy arises hereunder which causes the Termination of Escrow to take place more than eighteen (18) months after the Closing Date, or the Escrow Agent is made a party to any litigation pertaining to this Escrow Agreement or the subject matter hereof, then the Escrow Agent shall be compensated for such extraordinary services and reimbursed by the non-prevailing Party for all costs and expenses, including reasonable attorneys' fees and expenses, occasioned by any such delay, controversy, litigation, or event. If any amount due to the Escrow Agent hereunder is not paid within thirty (30) days of the date due, the Escrow Agent in its sole discretion may charge interest on such amount up to the highest rate permitted by applicable law.

3.5 Merger or Consolidation. Any corporation or association into which the Escrow Agent may be converted or merged, or with which it may be consolidated, or to which it may sell or transfer all or substantially all of its corporate trust business and assets as a whole or substantially as a whole, or any corporation or association resulting from any such conversion, sale, merger, consolidation, or transfer to which the Escrow Agent is a party ("Corporate Event"), shall be and become the successor escrow agent under this Escrow Agreement and shall have and succeed to the rights, powers, duties, immunities, and privileges as its predecessor, without the execution or filing of any instrument or paper or the performance of any further act. Escrow Agent shall notify the Parties of any such Corporate Event occurring prior to the Termination of Escrow.

3.6 Force Majeure. The Escrow Agent shall not be responsible or liable for any failure or delay in the performance of its obligation under this Escrow Agreement arising out of or caused, directly or indirectly, by circumstances beyond its reasonable control, including, without limitation, acts of God, earthquakes, fire, flood, wars, acts of terrorism, civil or military disturbances, sabotage, epidemic, riots, interruptions, loss, or malfunctions of utilities, computer (hardware or software) or communications services, accidents, labor disputes, acts of civil or military authority or governmental action; it being understood that the Escrow Agent shall use commercially reasonable efforts which are consistent with accepted practices in the banking industry to resume performance as soon as reasonably practicable under the circumstances.

(iv) use its commercially reasonable efforts to expeditiously register or qualify such Registrable Securities under such other securities or “blue sky” laws of California and New York if required by the laws of such states, and continue such registration or qualification in effect in such jurisdiction for as long as permissible pursuant to the laws of such jurisdiction, or for as long as any such seller requests or until all of such Registrable Securities are sold or are “covered securities” under the Securities Act, whichever is shortest, and do any and all other acts and things which may be reasonably necessary or advisable to enable any such seller to consummate the disposition of the Registrable Securities owned by such seller in such jurisdictions; provided, however, that the Company shall not be required to (x) qualify generally to do business in any jurisdiction where it would not otherwise be required to qualify but for this Section 3(b)(iv), (y) subject itself to taxation in any such jurisdiction or (z) consent to general service of process in any such jurisdiction;

(v) following its actual knowledge thereof, notify each seller of Registrable Securities: (A) when a Prospectus, any Prospectus supplement, any Free Writing Prospectus, a Registration Statement or a post-effective amendment to a Registration Statement has been filed with the Commission, and, with respect to a Registration Statement or any post-effective amendment, when the same has become effective; (B) of any request by the Commission for amendments or supplements to a Registration Statement, related Prospectus or Free Writing Prospectus or for additional information; (C) of the receipt by the Company of any notification with respect to the suspension of the qualification or exemption from qualification of any of the Registrable Securities for sale in any jurisdiction or the initiation or threatening of any proceedings for such purpose; and (D) of the existence of any fact or happening of any event of which the Company has knowledge which makes any statement of a material fact in such Registration Statement, related Prospectus or Free Writing Prospectus or any document incorporated or deemed to be incorporated therein by reference untrue or which would require the making of any changes in the Registration Statement, Prospectus or Free Writing Prospectus in order that, in the case of the Registration Statement, it will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading, and that in the case of such Prospectus or Free Writing Prospectus, it will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, provided that the Company need not disclose any facts or events that have not bee publicly disclosed by the Company;

(vi) upon the occurrence of any event contemplated by Section 3(b)(v)(D), as promptly as practicable, prepare a supplement or amendment to such Registration Statement, related Prospectus or Free Writing Prospectus and furnish to each seller of Registrable Securities a reasonable number of copies of such supplement to, or amendment of, such Registration Statement, Prospectus or Free Writing Prospectus as may be necessary so that, after delivery to the purchasers of such Registrable Securities, in the case of the Registration Statement, it will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading, and that in the case of such Prospectus or Free Writing Prospectus, it will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading;

(vii) enter into and perform customary agreements and take such other actions as are reasonably required in order to facilitate the disposition of such Registrable Securities and shall provide all reasonable cooperation, including causing counsel to the Company to deliver customary legal opinions in connection with any such underwriting agreements;

(viii) make available at reasonable times for inspection by any Inspector all financial and other records, pertinent corporate documents and properties of the Company and its subsidiaries (collectively, the “Records”) as shall be reasonably necessary to enable them to exercise their due diligence responsibility, and cause the Company’s and its subsidiaries’ officers, directors, managers and employees, and the Company’s independent registered public accounting firm, to supply all information reasonably requested by any such Inspector in connection with such Registration Statement. Records that the Company determines, in good faith, to be confidential and which it notifies the Inspectors are confidential shall not be disclosed by the Inspectors (and the Inspectors shall confirm their agreement in writing in advance to the Company if the Company shall so request) unless (x) the disclosure of such Records is necessary, in the Company’s reasonable judgment, to avoid or correct a misstatement or omission in the Registration Statement, (y) the release of such Records is ordered pursuant to a subpoena or other order from a court of competent jurisdiction after exhaustion of all appeals therefrom or (z) the information in such Records was known to the Inspectors on a non-confidential basis prior to its disclosure by the Company or has been made generally available to the public. Each seller of Registrable Securities agrees that it shall, upon learning that disclosure of such Records is sought in a court of competent jurisdiction, promptly give notice to the Company and allow the Company, at the Company’s expense, to undertake appropriate action to prevent disclosure of the Records deemed confidential;

(ix) if such sale is pursuant to an underwritten offering, obtain a “cold comfort” letter dated the effective date of the Registration Statement and the date of the closing under the underwriting agreement from the Company’s independent registered public accounting firm in customary form and covering such matters of the type customarily covered by “cold comfort” letters as the managing underwriter reasonably requests;

(x) furnish, at the request of any seller of Registrable Securities on the date such securities are delivered to the underwriters for sale pursuant to such registration, an opinion, dated such date, of counsel representing the Company for the purposes of such registration, addressed to the underwriters, covering such legal matters with respect to the registration in respect of which such opinion is being given as the underwriters, may reasonably request and are customarily included in such opinions;

(xi) cause any Shares included in the Registration Statement to be listed on each securities exchange on which the Shares are then listed. The Company shall pay all fees and expenses in connection with satisfying its obligation to list such Shares; The Company also represents that it is in compliance with the requirements of the NYSE Amex for continued listing of the Shares. The Company has taken no action designed to, or likely to have the effect of, terminating the registration of the Shares under the Exchange Act or the listing of the Shares on the NYSE Amex, nor has the Company received any notification that the Commission or the NYSE Amex is contemplating terminating such registration or listing. The transactions contemplated by this Agreement will not contravene the rules and regulations of the NYSE Amex. The Company will comply with all requirements of the NYSE Amex with respect to the issuance and listing of the Acquired Shares and shall cause the Acquired Shares to be listed on the NYSE Amex.

(xii) make all required filings of all Prospectuses and Free Writing Prospectuses with the Commission;

(xiii) make all required filing fee payments in respect of any Registration Statement or Prospectus used under this Agreement (and any offering covered thereby); and

(xiv) take all other steps reasonably necessary to effect the registration of the Registrable Securities contemplated hereby

(c) Seller Requirements. In connection with any offering under any Registration Statement under this Agreement, each Shareholder (i) shall promptly furnish to the Company in writing such information with respect to the Shareholder and the intended method of disposition of its Registrable Securities as the Company may reasonably request or as may be required by law or regulations for use in connection with any related Registration Statement or Prospectus (or amendment or supplement thereto) and all information required to be disclosed in order to make the information previously furnished to the Company by the Shareholder not contain a material misstatement of fact or necessary to cause such Registration Statement or Prospectus (or amendment or supplement thereto) not to omit a material fact with respect to the Shareholder necessary in order to make the statements therein not misleading; (ii) shall comply with the Securities Act and the Exchange Act and all applicable state securities laws and comply with all applicable regulations in connection with the registration and the disposition of the Registrable Securities; and (iii) shall not use any Free Writing Prospectus without the prior written consent of the Company. If any seller of Registrable Securities fails to provide such information required to be included in such Registration Statement by applicable securities laws or otherwise necessary or desirable in connection with the disposition of such Registrable Securities, within ten (10) calendar days after written request therefor, the Company may exclude such seller’s Registrable Securities from the registration statement.

(d) Notice to Discontinue. Each Shareholder agrees that, upon receipt of any notice from the Company of the happening of any event of the kind described in Section 3(b)(v)(D), the Shareholder shall forthwith discontinue disposition of Registrable Securities pursuant to the Registration Statement covering such Registrable Securities until the Shareholder’s receipt of the copies of the supplemented or amended Prospectus or Free Writing Prospectus contemplated by Section 3(b)(vi) (or if no supplemental or amended prospectus or Free Writing Prospectus is required, upon confirmation from the Company that use of the Prospectus or Free Writing Prospectus is once again permitted) and, if so directed by the Company, the Shareholder shall deliver to the Company (at the Company’s expense) all copies, other than permanent file copies then in the Shareholder’s possession, of the Prospectus or Free Writing Prospectus covering such Registrable Securities which is current at the time of receipt of such notice.

(e) Registration Expenses. The Company shall pay all expenses arising from or incident to its performance of, or compliance with, this Agreement, including, without limitation, (i) Commission, filing fees, (ii) all fees and expenses incurred in complying with state securities or “blue sky” laws (including reasonable fees, charges and disbursements of counsel to any underwriter incurred in connection with “blue sky” qualifications of the Registrable Securities as may be set forth in any underwriting agreement), (iii) all printing, messenger and delivery expenses, and (iv) the fees, charges and expenses of counsel to the Company and of its independent registered public accounting firm and any other accounting fees, charges and expenses incurred by the Company (including, without limitation, any expenses arising from any “cold comfort” letters and the reasonable and documented legal fees, charges and expenses of Shareholder’s Counsel and regardless of whether such Registration Statement is declared effective. All of the expenses described in the preceding sentence of this Section 3(e) are referred to herein as “Registration Expenses”.

4. Indemnification; Contribution

(a) Indemnification by the Company. The Company agrees to indemnify and hold harmless the Shareholders, and each of their respective partners, directors, officers, Affiliates, stockholders, members, employees, trustees, legal counsel and accountants and each Person who controls (within the meaning of Section 15 of the Securities Act) any Shareholder, from and against any and all losses, claims, damages, liabilities and expenses, or any action or proceeding in respect thereof (including reasonable costs of investigation and reasonable attorneys’ fees and expenses) (each, a “Liability” and collectively, “Liabilities”), arising out of or based upon (a) in the case of the Registration Statement or in any amendment thereto, any untrue, or allegedly untrue, statement of a material fact or omission, or alleged omission, to state any material fact required to be stated therein or necessary to make the statements therein not misleading; (b) in the case of the Disclosure Package, the Prospectus, any Free Writing Prospectus or in any supplement thereto, any untrue, or allegedly untrue, statement of a material fact or omission, or alleged omission, to state any material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading and (c) any violation or alleged violation by the Company of the Securities Act, the Exchange Act or any state securities law, or any rule or regulation thereunder, in connection with the performance of its obligations under this Agreement; provided, however, that the Company shall not be held liable in any such case to the extent that any such Liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission contained in such Disclosure Package, Registration Statement, Prospectus, Free Writing Prospectus or such amendment or supplement thereto solely in reliance upon and in conformity with information concerning any Shareholder furnished in writing to the Company by or on behalf of a Shareholder expressly for use therein, including, without limitation, the information furnished to the Company pursuant to Sections 3(c) and 4(b). The Company shall also provide customary indemnities to any underwriters of the Registrable Securities, their officers, directors and employees and each Person who controls such underwriters (within the meaning of Section 15 of the Securities Act) to the same extent as provided above with respect to the indemnification of the Shareholders.

(b) Indemnification by Shareholders. In connection with any offering in which any Shareholder is participating pursuant to this Agreement, each participating Shareholder agrees severally to indemnify and hold harmless the Company, any underwriter retained by the Company and each Person who controls the Company or such underwriter (within the meaning of Section 15 of the Securities Act) to the same extent as the foregoing indemnity from the Company to the Shareholders (including indemnification of their respective partners, directors, officers, Affiliates, stockholders, managers, members, employees, trustees and Controlling Persons), but only to the extent that Liabilities arise out of or are based upon a statement or alleged statement or an omission or alleged omission that was made solely in reliance upon and in conformity with information with respect to such Shareholder furnished in writing to the Company by or on behalf of the Shareholder expressly for use in such Disclosure Package, Registration Statement, Prospectus, Free Writing Prospectus or such amendment or supplement thereto, including, without limitation, the information furnished to the Company pursuant to Section 3(c). In no event shall the liability of a Shareholder hereunder be greater in amount than the net proceeds received by the Shareholder upon the sale of the Registrable Securities giving rise to such indemnification obligation except in the case of fraud by the Shareholder.

(c) Conduct of Indemnification Proceedings. Any Person entitled to indemnification or contribution hereunder (the “Indemnified Party”) agrees to give prompt written notice to the indemnifying party (the “Indemnifying Party”) after the receipt by the Indemnified Party of any written notice of the commencement of any action, suit, proceeding or investigation or threat made in writing for which the Indemnified Party intends to claim indemnification or contribution pursuant to this Agreement; provided, however, that the failure to so notify the Indemnifying Party shall not relieve the Indemnifying Party of any Liability that it may have to the Indemnified Party hereunder (except to the extent that the Indemnifying Party is materially prejudiced or otherwise forfeits substantive rights or defenses by reason of such failure). If notice of commencement of any such action is given to the Indemnifying Party as provided in this Section 4(c), the Indemnifying Party shall be entitled to participate in and, to the extent it may wish, jointly with any other Indemnifying Party similarly notified, to assume the defense of such action at its own expense, with counsel chosen by it and reasonably satisfactory to such Indemnified Party. Each Indemnified Party shall have the right to employ separate counsel in any such action and participate in the defense thereof, but the reasonable and documented out-of-pocket fees and expenses of such counsel shall be paid by the Indemnified Party unless (i) the Indemnifying Party agrees to pay the same, (ii) the Indemnifying Party fails to assume the defense of such action with counsel reasonably satisfactory to the Indemnified Party or (iii) the named parties to any such action (including any impleaded parties) include both the Indemnifying Party and the Indemnified Party and such parties have been advised by such counsel that either (x) representation of such Indemnified Party and the Indemnifying Party by the same counsel would be inappropriate under applicable standards of professional conduct or (y) there may be one or more legal defenses available to the Indemnified Party which are different from or additional to those available to the Indemnifying Party. In any of such cases, the Indemnifying Party shall not have the right to assume the defense of such action on behalf of such Indemnified Party, it being understood, however, that the Indemnifying Party shall not be liable for the reasonable and documented out-of-pocket fees and expenses of more than one separate firm of attorneys (in addition to any local counsel) for all Indemnified Parties and all such reasonable and documented out-of-pocket fees and expenses shall be reimbursed as incurred. No Indemnifying Party shall be liable for any settlement entered into without its written consent, which consent shall not be unreasonably withheld. No Indemnifying Party shall, without the consent of such Indemnified Party, effect any settlement of any pending or threatened proceeding in respect of which such Indemnified Party is a party and indemnity has been sought hereunder by such Indemnified Party, unless such settlement includes an unconditional release of such Indemnified Party from all liability for claims that are the subject matter of such proceeding.

(d) Contribution. If the indemnification provided for in this Section 4 from the Indemnifying Party is unavailable to an Indemnified Party hereunder or insufficient to hold harmless an Indemnified Party in respect of any Liabilities referred to herein, then each Indemnifying Party, in lieu of indemnifying such Indemnified Party, shall contribute to the amount paid or payable by such Indemnified Party as a result of such Liabilities in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party and Indemnified Party in connection with the actions which resulted in such Liabilities, as well as any other relevant equitable considerations. The relative faults of such Indemnifying Party and Indemnified Party shall be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact, has been made by, or relates to information supplied by, such Indemnifying Party or Indemnified Party, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such action. The amount paid or payable by a party as a result of the Liabilities referred to above shall be deemed to include, subject to the limitations set forth in Sections 4(a), 4(b), and 4(c) , any reasonable and documented out-of-pocket legal or other fees, charges or expenses reasonably incurred by such party in connection with any investigation or proceeding.

(i) The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 4(d)) were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to in the immediately preceding paragraph. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation. In no event shall a Shareholder be required to contribute an amount under this Section 4(d) in excess of the net proceeds received by the Shareholder upon the sale of the Shareholder’s Registrable Securities pursuant to the Registration Statement giving rise to such contribution obligation, except in the case of fraud by the Shareholder.

5. Reports Under Exchange Act

(a) With a view to making available to the Shareholders the benefits of Rule 144 promulgated under the Securities Act and any other rule or regulation of the Commission that may at any time permit the Shareholders to sell Registrable Shares of the Company to the public without registration, the Company agrees for the period of at least one year from the date hereof, to:

Opinion of Xennex Counsel

May ___, 2012

BioTime, Inc.

0000 Xxxxxx Xxx Xxxxxxx, Xxxxx 000

Xxxxxxx, XX 00000

Re:

Agreement and Plan of Merger, dated as of this date, by and among Xennex. Inc. ("Xennex"): LifeMap Sciences, Inc. ("LifeMap"); BioTime. Inc. ("BioTime"). and the Xennex Stockholders (the "Merger Agreement")

Gentlemen:

You have asked us for our opinion on the matters addressed below. Although we have acted as counsel to Xennex, our representation is limited to matters individually referred to us by Xennex. Specifically, we have acted as counsel to Xennex in connection with the execution and delivery of the Merger Agreement.

For the purpose of rendering the opinions expressed below, we have examined and relied upon originals or copies, certified or otherwise identified to our satisfaction, of such records, agreements, documents, and other instruments, and certificates or comparable documents of public officials and of officers and representatives of Xennex, and have made such inquiries of such officers and representatives as we have deemed necessary. We have assumed the genuineness of all signatures, the conformity to the originals of all documents reviewed by us as copies, the authenticity and completeness of all original documents reviewed by us in original or copy form and the legal competence of each individual executing any document. We have furthermore assumed that LifeMap and BioTime have all requisite power and authority to execute, deliver, and perform the Merger Agreement and the other agreements and instruments to be executed, delivered, or performed by either of them pursuant thereto, that LifeMap and BioTime have duly and validly executed and delivered the Merger Agreement and such other agreements and instruments and that they constitute valid, binding, and enforceable obligations of LifeMap and BioTime.

As to all matters of fact (including factual conclusions and characterizations and descriptions of purpose, intention or other state of mind), we have relied entirely upon representations made to us by the officers of Xennex and have assumed, without independent inquiry, the accuracy of those representations. However, we are not aware of any information which would cause us to question the accuracy of such representations.

When an opinion set forth below is given to the best of our knowledge, or to our knowledge, or with reference to matters of which we are aware or which are known to us, or with another similar qualification, the relevant knowledge or awareness is limited to the actual knowledge or awareness of the individual lawyers in the firm who have participated directly in the specific transactions to which this opinion relates and without any special or additional investigation undertaken for the purposes of this opinion. The opinions expressed herein are based solely on matters of which the individual lawyers in the firm who have participated directly in the matters referred to our firm by management of Xennex have actual knowledge.

Each opinion set forth below relating to the enforceability of any agreement or instrument against Xennex is subject to the following general qualifications:

(i) as to any instrument delivered by Xennex, we assume that Xennex has received the agreed to consideration therefor;

(ii) as to any agreement to which Xennex is a party, we assume that such agreement is the binding obligation of each other party thereto;

(iii) the enforceability of any obligation of Xennex may be limited by bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium, marshaling or other laws and rules of law affecting the enforcement generally of creditors' rights and remedies (including such as may deny giving effect to waivers of debtors' or guarantors' rights);

(iv) the enforcement of any of your rights may in all cases be subject to an implied duty of good faith and to general principles of equity (regardless of whether such enforceability is considered in a proceeding at law or in equity); and

(v) no opinion is given herein as to the availability of any specific or equitable relief of any kind or as to the enforceability of any particular remedy provided in the Merger Agreement or any associated agreement or instrument.

In connection with this opinion, we have examined and relied upon the following:

A. The Merger Agreement;

B. Articles of Organization (as amended) and By-Laws (as amended) of Xennex;

C. Unanimous Written Consent of the Shareholders and Directors of Xennex.

Based upon the foregoing, it is our opinion that:

1. Xennex is a corporation duly organized, validly existing and in good standing under the law of Massachusetts, and has all requisite power to own its property and conduct its business as now conducted.

2. The Merger Agreement has been duly authorized and has been duly and validly executed and delivered by or on behalf of Xennex and the execution, delivery and performance of such Merger Agreement is within the power of Xennex and constitutes legal, valid and binding obligations of Xennex and is enforceable in accordance with its terms.

3. To the best of our knowledge, neither the execution, the delivery nor the performance of the Merger Agreement, nor compliance with its terms and provisions will or has conflicted with or resulted in a breach of any of the terms, conditions or provisions of the Articles of Organization (as amended) or By-Laws (as amended) of Xennex or of any law, rule or any regulation, order, writ, injunction, decree, determination or award of any court or governmental instrumentality.

4. To the best of our knowledge, no consent, license, approval or authorization, or registration, declaration or filing with, any court, governmental body or authority or other person or entity is required, in connection with the valid execution, delivery or performance of the Merger Agreement.

This opinion is solely for the benefit of the addressee hereof in connection with the transaction contemplated herein and may not be relied upon by you for any other purpose or by any other person without the undersigned's prior written consent. All of the foregoing opinions are rendered as of the date hereof. We assume no obligation to update such opinions to reflect any facts or circumstances that may hereafter come to our attention or any changes in the law that may hereafter occur.

	Very truly yours,


	Xxxxxxxx, Xxx & Xxxxx, LLP

Yeda and Xennex are parties to a certain Research and License Agreement dated June 9, 2003, as amended by the First Amendment dated February 18, 2004, a Second Amendment dated June 29, 2004, a Third Amendment dated November 13, 2004, a Fourth Amendment dated February 17, 2005, a Fifth Amendment dated April 17, 2008, a Sixth Amendment dated August 16, 2010 and a Seventh Amendment dated October 27, 2011 (collectively the "GeneCards R&L Agreement") as well as a certain Research and License Agreement dated July 10, 2011 (the "PanDaTox R&L Agreement"). (Combined, the GeneCards R&L Agreement and the PanDaTox R&L Agreement shall be termed the “R&L Agreements”).

B. Xennex desires to assign all its rights and obligations under the R&L Agreements to LifeMap, and LifeMap desires to assume all such rights and obligations, upon the terms and conditions set forth herein.

C. The above mentioned designated assignment of the R&L Agreements from Xennex to LifeMap is derived from the desire of Xennex and LifeMap to merge Xennex into LifeMap (the “Merger”) and execute a Merger agreement (the “Merger Agreement”), and the Parties intend that the Merger Agreement and this Agreement will be executed simultaneously and that this Agreement shall not enter into effect until the date on which the Merger is effective.

D. Xennex and LifeMap desire to obtain the consent of Yeda to the assignment of the R&L Agreements to LifeMap through the Merger and subject to its completion as described in the final draft of the Merger Agreement provided to Yeda.

Now therefore, the parties agree as follows:

AGREEMENT

ASSIGNMENT.

1.1 Based on the representations and warranties of Xennex, LifeMap and BioTime, Yeda hereby consents to the assignment of the R&L Agreements from Xennex to LifeMap pursuant to, and upon consummation of, the Merger, subject to the full receipt of the consideration described in Section 2 below. LifeMap hereby agrees to accept such assignment and to assume all of Xennex’s right, title, interest and obligations under the R&L Agreements upon consummation of the Merger, and to keep, perform, comply with and fulfill all of the terms and obligations of Xennex under the R&L Agreements, to which it shall be a party instead of Xennex, commencing on and after the consummation of the Merger. For the avoidance of doubt, pursuant to the assignment, LifeMap shall use its commercially reasonable efforts to develop, market and commercialize the technologies licensed under the R&L Agreements, as set forth in the R&L Agreements.

For the avoidance of any doubt, if the full consideration described in Section 2 below is not received by Yeda, Yeda’s consent to the assignment, as aforesaid, shall be deemed to be void, and such default shall be deemed to be a material breach of this Agreement, that shall entitle Yeda to terminate this Agreement and the R&L Agreements, without derogating from any other remedy or relief that Yeda is entitled to by virtue of law or agreement.

CONSIDERATION.

2.1 In consideration of Yeda’s consent to the assignment of the R&L Agreements to LifeMap through the Merger, within ten (10) business days after the Xennex Stockholders receive shares of LifeMap common stock, no par value (“LifeMap Shares”), in the Merger, they shall transfer to Yeda a total of [*Certain information has been omitted under a request for confidential treatment, and the omitted information has been filed with the Commission] shares of such LifeMap Shares which will constitute [*Certain information has been omitted under a request for confidential treatment, and the omitted information has been filed with the Commission].

[*Certain information has been omitted under a request for confidential treatment, and the omitted information has been filed with the Commission]

2.2 In addition, as further consideration for Yeda’s consent to the assignment of the R&L Agreements to LifeMap through the Merger, the Xennex Stockholders agree that within ten (10) business days after receipt of BioTime common shares, no par value (“BioTime Shares”), by them in the Merger, they shall deliver to Yeda a number of such BioTime common shares having a market value of [*Certain information has been omitted under a request for confidential treatment, and the omitted information has been filed with the Commission] as of the “Closing Date” (as defined in the Merger Agreement); provided, however, that the assignment of such BioTime common shares to Yeda is subject to the condition that BioTime shall have received from Yeda an investment representation letter, in form attached hereto as Exhibit B, duly executed by Yeda, containing representations, warranties, and agreements concerning Yeda’s investment intent with respect to such BioTime Shares and the applicable restrictions on transfer under the Securities Act of 1933, as amended (the “Securities Act”) and applicable state and foreign securities laws. Yeda agrees that the stock certificates evidencing such BioTime Shares shall bear such legends as BioTime may require pertaining to restrictions on transfer under the Securities Act and applicable state and foreign securities laws. All of the above LifeMap Shares and BioTime Shares shall be transferred to Yeda within 10 business days after receipt by the Xennex Stockholders and none of the shares intended for Yeda hereunder shall be held in escrow (notwithstanding the arrangements with the Xennex Stockholders under the Merger Agreement).

2.3 All LifeMap Shares and BioTime Shares held by Yeda shall be subject to and enjoy the same terms and rights as such shares issued to, and held by, the Xennex Stockholders under the Merger Agreement and/or any other agreement as consideration for the merger of Xennex into LifeMap. In addition, Yeda and the Xennex Stockholders shall enter into a Right of First Refusal and Shareholders Agreement, of even date, in the form attached to the Merger Agreement. Yeda shall be entitled to tag-along rights on

(a) any BioTime Shares issued to Xennex Stockholders in the Merger. If any or all of the Xennex Stockholders elect to sell any or all of their BioTime Shares that are subject to Yeda’s tag-along rights, after receiving a bona fide binding offer for such shares from a third party (excluding (a) sales of shares on a national securities exchange or in the over-the-counter market or on any electronic trading system, and (b) transfers of shares to any revocable or irrevocable trust), Yeda shall be entitled to sell, under same terms and conditions offered to the Xennex Stockholders, a number of BioTime Shares (the “Tag-Along Shares”) equal to the product of (x) the total number of BioTime Shares then beneficially owned by Yeda multiplied by (y) a fraction, the numerator of which shall be the total number of BioTime Shares proposed to be purchased by the third party and the denominator of which shall be the sum of all BioTime Shares beneficially owned by Yeda and the Xennex Stockholders who have elected to participate in the transaction. In the event of a proposed sale of BioTime Shares that are subject to Yeda’s tag-along rights by any Xennex Stockholder, such Xennex Stockholder shall provide prompt written notice (the “Notice”) of the terms of such sale to Yeda. The Notice shall identify the purchaser, the number of shares which the purchaser is seeking to purchase or otherwise acquire, the price contained in the offer and all the other terms and conditions of the offer. In the event an offeror shall modify the offer in any way, the applicable Xennex Stockholder shall send an amended Notice to Yeda. Yeda shall, within 10 days after the date of the Notice, or amended Notice if applicable, is provided, deliver a written notice to the applicable Xennex Stockholder that was the recipient of the offer, which notice shall specify the number of Tag-Along Shares that Yeda wishes to sell pursuant to the offer, and the total number of shares then beneficially owned by Yeda. If Yeda elects to sell fewer than the number of Tag-Along Shares that it is entitled to sell in the proposed sale or does not provide to Xennex Stockholders a written notice of acceptance within such 10 day period, then the Xennex Stockholders shall be able to enter into an agreement for the sale of their shares and Yeda will be treated as having waived their tag-along rights; and

(b) LifeMap Shares held by all LifeMap shareholders in accordance with Section 1.7 of the Right of First Refusal and Shareholder’s Agreement. However, to the extent that Section 1.7 of such agreement shall be deleted and/or amended after the date hereof without the express written consent of Yeda, then Yeda shall be entitled to a tag along right vis-à-vis the Xennex Stockholders with respect to any sale by all or any of such Xennex Stockholders of their LifeMap Shares, under the same terms of the tag along right granted in paragraph (a) above, that shall apply mutatis mutandis.

All tag-along rights afforded Yeda, by the Xennex Stockholders, via this Agreement, or any other agreement shall expire (a) after a change in control of LifeMap which is defined as a transfer of ownership in which the new owner obtains a fifty percent or greater ownership interest in LifeMap (for the avoidance of doubt, tag along rights will apply in connection with the transfer that caused the change of control), (b) upon an initial public offering of LifeMap Shares, or (b) LifeMap Shares becoming registered under the Securities Exchange Act of 1934, as amended and being listed for trading on a U.S. national securities exchange or OTC Bulletin Board.

2.4 It is also agreed that all of the shares issued to Yeda shall be transferable to Yeda’s “Permitted Transferees” (as defined in that certain Right of First Refusal and Shareholder Agreement of even date, including the Weizmann Institute of Science and/or any employee of the Weizmann Institute of Science, without any restrictions other than approvals required by law and/or by the Right of First Refusal and Shareholder Agreement and the Investment Representation Letter of even date. Permitted Transferees shall be entitled to all of the rights herein (including but not limited to the Tag-Along Rights per Section 2.3 above), provided that the Permitted Assignee executes and delivers to LifeMap a counterpart of the Right of First Refusal and Shareholders Agreement.

REPRESENTATIONS OF XENNEX, LIFEMAP AND BIOTIME.

3.1 LifeMap, BioTime and Xennex represent that the Capital Table attached as Exhibit A shows, on a fully diluted basis the number of shares of LifeMap that LifeMap expects will be outstanding or issuable following the consummation of the Merger [*Certain information has been omitted under a request for confidential treatment, and the omitted information has been filed with the Commission] that LifeMap is not a party to any other agreements or arrangements to issue any additional shares in connection with the acquisition of Xennex, and that there will not be an increase to the proportions of the Xennex shares (as designated in the Capital Table) and/or the stock options granted to the Xennex Stockholders in their roles as LifeMap management under this transaction, nor is there an understanding between any of the Parties other than Yeda that such an increase will be made at a later date.

3.2. LifeMap, BioTime and Xennex represent that the Xennex Stockholders will receive reasonable compensation (salaries, bonuses, incentive payments and stock options), for their active roles in managing LifeMap and/or its subsidiaries, subject to employment agreements and stock option agreements and that no other agreements exist that will compensate Xennex or Xennex Stockholders for the transaction contemplated in the Merger Agreement.

3.3 For avoidance of doubt, it is hereby agreed and acknowledged by LifeMap that the income generating royalties to Yeda under the R&L Agreements, shall include any amount received by LifeMap or any Affiliated Entity (as such terms are defined in the R&L Agreements) in connection with the operation of the GeneCards Package, the MalaCards Package or PanDatox Databases Package [*Certain information has been omitted under a request for confidential treatment, and the omitted information has been filed with the Commission] (“Additional Revenue”). Xennex represents that it has paid to Yeda all Sublicensing Fees currently due to be paid to Yeda, under the R&L Agreements up to the date of signature of this Assignment Agreement, including royalties derived from any Additional Revenue, as aforesaid, and that to the best of its knowledge, Yeda has no claim for any unpaid Sublicensing Fees. The Parties agree to cooperate and execute appropriate amendments to the R&L Agreements to implement the above, however, in any event that such amendments are not signed, for any reason, the aforesaid, shall be deemed to be the mutual current understanding of the parties, and shall serve as such amendments.

CONTINUATION OF R&L AGREEMENTS.

4.1 Subject to Section 1 above, Yeda and Xennex hereby represent and warrant to LifeMap and BioTime that the R&L Agreements are currently in full force and effect and there are no known breaches of either of the R&L Agreements by any of the parties thereto, and that no known event has occurred that, with the giving of notice or passage of time or both would entitle Yeda to terminate either of the R&L Agreements.

4.2 It is hereby acknowledged and agreed that nothing in this Agreement, or the Right of First Refusal and Shareholders Agreement, or LifeMap’s articles of incorporation or bylaws, or any other agreement between LifeMap shareholders, shall derogate from the rights and remedies of Yeda under any of the R&L Agreements (as may be amended or supplemented). It is furthermore acknowledged and agreed that Yeda’s rights and obligations as a LifeMap shareholder (including, without limitations, any obligation of Yeda, as a shareholder of LifeMap and not as a licensor under the R&L Agreements, to vote in favor of any merger or consolidation of LifeMap or any sale of LifeMap assets, or any change of LifeMap’s business) shall not adversely affect Yeda’s rights under the R&L Agreements and any such vote or other action shall not estop Yeda from exercising its rights and remedies under the R&L Agreements.

GOVERNING LAW AND JURISDICTION.

5.1 This Agreement shall be governed in all respects by the laws of the State of Israel and the courts of Tel Aviv shall have exclusive jurisdiction over any disputes arising hereunder.

5.2 Without prejudice to the right of Yeda to make service in any other manner permitted by law, LifeMap, BioTime, Xennex Stockholders and Xennex (if then existed):

5.2.1 Appoint Xx. Xxxxx Xxxxxxxxxx of Xxxxxxx 0, Xxx Xxxx as their agent for service of process in relation to any suit or proceedings before the Israeli courts in connection with this Agreement;

5.2.2 Agree to maintain such an agent for service of process in Israel or if such appointment of Xxxxx Xxxxxxxxxx ceases to be effective for any of them, appoint another person in Israel to accept service of process on its behalf in Israel and notify Yeda in writing of such new appointment, within 5 (five) business days.

MISCELLANEOUS.

6.1 Yeda here by agrees that Xennex, LifeMap or any parent company may disclose the terms of this Agreement and the R&L Agreements to the extent required under the securities or other disclosure laws and regulations of any country or state or the rules and regulations of any securities exchange or electronic securities trading system. If time permits, a draft of any planned public disclosure, (other than disclosure that repeats or restates prior approved public disclosure), will be provided to Yeda for its review and comment. If Xennex, LifeMap or a parent company files a copy of this Agreement or the R&L Agreements with the Securities and Exchange Commission or any similar state or foreign regulatory agency as an exhibit to any registration statement, application, or report, they shall submit to such agency an application for confidential treatment seeking permission to redact from such filing the principal financial terms of this Agreement or the R&L Agreements and the names of scientists included in the R&L Agreements and any other information reasonable requested by Yeda; provided, however, that Xennex, LifeMap or a parent company may disclose financial terms of this Agreement or the R&L Agreements in any such registration statement, application, or report to the extent they determine in good faith that doing so is necessary to make any statements contained therein not misleading

6.2 This Agreement and the attached Exhibits constitute the full and entire understandings and agreements among the parties with regard to the subject matter of this Agreement and in any case of a conflict with regard to such subject matter with other agreements (including the articles of incorporation or bylaws of BioTime or LifeMap) , the understandings and agreements herein shall prevail.

(LifeMap), stockholders of Xennex have agreed to transfer to us, Yeda Research and Development Company, Ltd., [* certain information has been omitted under a request for confidential treatment, and the omitted information has been filed with the Commission] BioTime, Inc. common shares, no par value (BioTime Shares) and [* certain information has been omitted under a request for confidential treatment, and the omitted information has been filed with the Commission] shares of LifeMap common stock, no par value (LifeMap Shares) in consideration for our consent to the assignment, by way of the merger with LifeMap, of Xennex’s rights under that certain Research and License Agreements with us. In that regard and in connection with the consent of BioTime and LifeMap to the transfer of the BioTime Shares and LifeMap Shares to us, we represent and warrant to, and agree with, BioTime and LifeMap as follows:

1. We and our attorneys, accountants, and financial advisors have been provided with a reasonable opportunity to make an investigation of BioTime and LifeMap in connection with the receipt of the BioTime Shares and LifeMap Shares. In this regard, we have also received a copy of BioTime’s Annual Report on Form 10-K for the year ended December 31, 2011 and a copy of its proxy statement for its last annual meeting of shareholders.

2. We understand that the BioTime Shares and LifeMap Shares are being offered and sold without registration under the United States Securities Act of 1933, as amended (the Securities Act), or registration or qualification under the California Corporate Securities Law of 1968, the laws of other states of the United States, or under the laws of any other state or jurisdiction, in reliance upon the exemptions from such registration and qualification requirements for non-public offerings. We acknowledge and understand that the availability of the aforesaid exemptions depends in part upon the accuracy of certain of the representations, declarations, and warranties contained herein, which we are making with the intent that they may be relied upon by BioTime and LifeMap and their respective directors and officers. We understand and acknowledge that no United States federal, state, or other agency has reviewed or endorsed the offer or sale of the BioTime Shares and LifeMap Shares or made any finding or determination as to the fairness of the offering or sale of the BioTime Shares and LifeMap Shares.

3. We, either alone or together with our attorneys, accountants, and financial advisors, have such knowledge and experience in financial and business matters to enable us to evaluate the merits and risks of the ownership of the BioTime Shares and LifeMap Shares.

4. We are receiving the BioTime Shares and LifeMap Shares solely for our own account and not with a view to resale or distribution except as described in paragraph 6 below.

5. It has never been represented, guaranteed, or warranted to us by BioTime, Inc., LifeMap, Xennex, or by any officer, director, shareholder, employee, or agent of BioTime, Inc., LifeMap, or Xennex that we will realize any specific value, sale price, or profit as a result of our ownership of the BioTime Shares and LifeMap Shares

6.

BioTime and LifeMap shall pay the fees of their respective counsel incurred in issuing such opinions. Notwithstanding the above, a transfer or assignment of either the BioTime Shares or LifeMap Shares to a “Permitted Assignee” (as defined in the Registration Rights Agreement of even date) shall be permitted provided that such Permitted Assignee agrees to be bound by the provisions of this letter.

7. We acknowledge that the certificates evidencing the BioTime Shares and LifeMap Shares to be issued to us will contain the following legend or a similar legend as may be utilized by the transfer agent of BioTime Shares at the time of issuance:

THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933.

Should any Shareholder or Permitted Transferee (as defined below) (in each case a “Selling Shareholder”) propose to accept one or more bona fide offers (collectively, the “Purchase Offer”) from any person or persons to purchase all or a portion of the common shares, no par value, of the Company (“Common Stock”) or shares of any other class or series of the Company that the Selling Shareholder now owns or may hereafter acquire through any stock split, stock dividend, or recapitalization or reclassification of the Common Stock (“Other Stock”), then the Selling Shareholder shall promptly notify the Company and each Shareholder of the terms and conditions of such Purchase Offer (the “Notice”) at least thirty (30) days prior to the closing of such sale or transfer (collectively “Transfer”). The Notice shall describe in reasonable detail the proposed Transfer including, without limitation, the number of shares of each class or series to be sold or transferred (the “Offered Shares”), the nature of such sale or transfer, the consideration to be paid, and the name and address of each prospective purchaser or transferee.

1.2 Company Right of First Refusal. The Company shall have the right, upon written notice to the Selling Shareholder given within twenty (20) days after receipt of the Notice of the Purchase Offer, to purchase any or all the Offered Shares on the same terms and conditions as the Purchase Offer.

1.3 Shareholder Right of First Refusal. In the event that the Company does not exercise its right pursuant to Section 1.2 with respect to all of the Offered Shares, the Selling Shareholder shall notify each other Shareholder (each a “Non-Selling Shareholder”) in writing of the Company’s failure to so exercise its right with respect to the shares being sold, and each Non-Selling Shareholder shall have the right, exercisable within twenty (20) days after receipt of such Notice, to purchase the remaining Offered Shares on the same terms and conditions as specified in the Notice.

(a) Each Non-Selling Shareholder may purchase all or any part of its pro rata share of the remaining Offered Shares specified in the Notice. If any Non-Selling Shareholder fails to elect to fully participate in such purchase pursuant to this Section, the Selling Shareholder shall give notice of such failure to the Non-Selling Shareholders who did so elect (the “Participants”). The Participants shall have five (5) days from the date such notice was given to agree (which may be done by telephone and subsequently confirmed in writing) to purchase all or any part of their pro rata share of the unsold portion of the Offered Shares; provided, however, that if any Participant fails to purchase its full pro rata share of the unsold portion of the Offered Shares, any other Participant may purchase some or all of such Participant’s pro rata share. For purposes of this paragraph, a Non-Selling Shareholder’s or Participant’s pro rata share shall be the ratio of (x) the number of shares of Common Stock or Other Stock (as applicable based on whether the right is being exercised with respect to Common Stock or Other Stock) held by such party to (y) the total number of shares of Common Stock or Other Stock (as applicable based on whether the right is being exercised with respect to Common Stock or Other Stock) held by all of the Non-Selling Shareholders and/or Participants (as applicable).

(b) The purchase of the shares shall take place within twenty (20) days of the Company’s election to purchase the Offered Shares pursuant to Section 1.2, or the Company’s and/or Participants’ election to purchase the Offered Shares, whichever is later, or at such other time as is mutually agreed to by the Selling Shareholder, the Company and the Participants. The Selling Shareholder shall deliver to the Company and/or Participants electing to purchase the shares offered by the Selling Shareholder stock certificates, evidencing the Common Stock or Other Stock being sold, duly endorsed for transfer to the purchaser(s) against payment of the purchase price by check for good funds or wire transfer to the Selling Shareholder’s account.

(c) In the event that the Company and/or the Participants fail to agree to purchase all of the Offered Shares pursuant to Section 1.2 and Section 1.3 within the period set out above, such Selling Shareholder shall have sixty (60) days after the expiration of the above period to sell all of the Offered Shares to the Buyer at the price and upon terms and conditions no more favorable to the Buyer than specified in the Notice pursuant to this Section 1.3. In the event that such Selling Shareholder has not sold all of the Offered Shares to the Buyer within sixty (60) days after the expiration of the above period, as applicable, or wishes to transfer any such shares at a price per share which is lower than that set forth in the notice, or upon terms different from those previously offered to the Company and the Participants, then such Selling Shareholder shall not thereafter sell any shares without first offering such shares to the Company and the Participants in the manner provided above. In the event that the above transactions require approval of the Company’s Board of Directors under applicable law, the Parties all agree to cause the Company’s Board of Directors to approve accordingly.

1.4 Ongoing Rights. The exercise or non-exercise of the first-refusal rights of the Shareholder hereunder shall not adversely affect the rights of such Shareholder to participate in subsequent purchases or sales by any Selling Shareholder pursuant to this Article 1.

1.5 Permitted Exemptions. Subject to Section 1.6, the rights of the Company pursuant to Section 1.2 and the rights of the Shareholders pursuant to Section 1.3 and Section 1.7 shall not apply to (a) any pledge made by a Shareholder pursuant to a bona fide loan transaction which creates a mere security interest or a sale by the secured party to realize upon collateral upon a default by the Shareholder in the payment of the loan, (b) any sale or transfer to the Company except that Section 1.7 shall apply to purchases by the Company through the exercise of its rights under Section 1.2, (c) any transfer by will or the laws of descent, (d) any transfer to the ancestors or descendants or spouse of a Shareholder or a trust for their benefit, (e) any transfer to or from a revocable intervivos trust of which a Shareholder is a settlor and beneficiary, (f) any sale or transfer to BioTime, Inc. or to any subsidiary or parent of BioTime, Inc., (g) any transfer by BioTime, Inc. pro rata to its shareholders of record as of a date determined by BioTime, Inc., (h) any sale or transfer to an Affiliate of a Shareholder or to employees of the Shareholder or such Shareholder’s Affiliate (which, for the avoidance of doubt, in the case of Yeda, shall include the Weizmann Institute of Science and/or any employee of the Weizmann Institute of Science) or (i) any sale or exchange pursuant to any offer made to purchase all of the shares owned by all Shareholders if the price per share and payment terms offered are the same for all Shareholders. Any transferee of shares under this Section shall be a “Permitted Transferee.”

1.6 Transferees Bound. Permitted Transferees of shares under clauses (c), (d), (e), (f) and/or (h) of Section 1.5, and each purchaser of shares from a Selling Shareholder pursuant to an offer to which Sections 1.2 and 1.3 apply, shall take the Shareholder’s shares subject to the obligations of the Shareholder and rights of the Company and other Shareholders under this Agreement with respect to any subsequent sale or other transfer of the shares received from the transferring Shareholder. It shall be a condition of any transfer of shares of Common Stock or Other Stock that the transferee, other than a Permitted Transferee that is already a party to this Agreement or a Permitted Transferee under clause (b), (g), or (h) of Section 1.5, executes a counterpart of this Agreement or an undertaking (in a form approved by the Company) to observe and perform the provisions and obligations of this Agreement, and furnishes such counterpart or undertaking to the Company. In the absence of such counterpart or undertaking being executed and furnished to the Company, a transfer shall be null and void and the transferee shall not be recognized by the Company as the holder or owner of the shares which are subject of such transfer for any purpose (including, without limitation, voting or dividend rights).

1.7 Tag Along Right. Each Non-Selling Shareholder who does not elect to purchase Offered Shares under Section 1.3 (“Entitled Shareholder”) shall have the option, exercisable by written notice to the Selling Shareholder, within 10 business days after receipt of the Notice, to require the Selling Shareholder to provide as part of its proposed Transfer, that such Entitled Shareholder be given the right to participate and Transfer up to such Entitled Shareholder's Tag Along Ratio. For purposes of this Section 1.7, the Entitled Shareholder’s “Tag Along Ratio” shall be determined with respect to each class of stock proposed to be Transferred by multiplying the total number of shares of such class proposed to be Transferred in the proposed transaction by a fraction, the numerator of which is the number of shares of such class owned by such Entitled Shareholder and the denominator of which is the total number of issued and outstanding shares of such class held by the Selling Shareholder and all Entitled Shareholders who have elected to participate in such Transfer. The Tag Along Ratio of Common Stock or Other Stock held by each Entitled Shareholder who elects to participate in the Transfer shall be included in the shares being Transferred to the proposed transferee or sold to the Company or other Shareholders under Sections 1.2 and 1.3, and the number of shares of Common Stock or Other Stock, as applicable, that may be Transferred in the transaction by the Selling Shareholder shall be reduced by the number of shares of the Entitled Shareholders so included.. The exercise of tag along rights by Entitled Shareholders shall not increase the number of shares that the proposed transferee must acquire in the Transfer. For the avoidance of doubt, such Transfer shall be also subject to the right of first refusal under Sections 1.2 and 1.3, provided however that each of the Shareholders shall be required to elect, within a period of 10 business days after the Notice is given, to exercise only their rights under Section 1.3 or under this Section 1.7 with respect to a proposed Transfer. Any changes or amendments to this Section 1.7 shall require the unanimous written approval of all of the Shareholders.

ARTICLE 2

Other Restrictions on Transfer; Shareholders Consent

2.1 Additional Restrictions on the Transfer. The Shareholders agree not to offer or sell any shares of Common Stock or Other Stock to any person or entity that is engaged, directly or indirectly through one or more intermediaries or controlled entities, in the research, development, production, or sale of human therapeutic products using human embryonic stem cell or induced pluripotent stem cells or related technology, unless such offer or sale has been approved by the a majority of the directors of the Company other than the Shareholder(s) intending to so transfer or sell Common Stock or Other Stock.

2.2 Changes in Stock. If, from time to time during the term of this Agreement, (a) there is a dividend of any security, stock split, recapitalization, reclassification of shares, or other change in the character or amount of any of the outstanding Common Stock or Other Stock, or (b) there is any consolidation or merger immediately following which shareholders of the Company hold more than 50% of the voting equity securities of the surviving corporation, then, in such event, any and all new, substituted or additional capital stock or other securities which any Shareholder or Permitted Transferee receives through such transaction on account of ownership of shares Common Stock or Other Stock shall be immediately subject to the provisions of this Agreement with the same force and effect as the shares currently held by any Shareholder presently subject to this Agreement.

2.3 Amendment of Corporate Documents. Notwithstanding anything to the contrary in this Agreement, in the Company's Articles of Incorporation and in the Company's Bylaws, the adoption of any action or resolution amending or altering Article VII of the Company’s Bylaws, as in affect as of the date hereof, in such manner that would eliminate or limit the right of Shareholders to examine or receive copies of corporate records and financial statements as currently provided under such Article VII , shall require the vote or written consent of 80% of the holders of shares affected by such amendment or alteration.

2.4 Special Resolutions. Notwithstanding anything to the contrary in this Agreement, in the Company's Articles of Incorporation and in the Company's Bylaws the prior affirmative vote or written consent of the holders of 80% of the then-outstanding shares of Common Stock and Other Stock shall be required for any sale, provision of exclusive license, transfer or assignment of all or substantially all of the Company's rights (including intellectual property rights) in and to Company’s Research and License Agreement (the “R&L Agreement”) entitling the Company to commercialize its GeneCards data base, if such sale, license, transfer or assignment is proposed to be made to any Affiliate of the Company; provided, however, that this Section 2.4 shall not apply to a sale, license, transfer or assignment to a subsidiary controlled by the Company or by means of a merger or consolidation of the Company with an Affiliate if the Company is the surviving corporation or if the Shareholders have dissenter’s rights of appraisal with respect to the merger or consolidation.

For the avoidance of doubt, this provision, along with any other provision in this agreement, remains subject to the Company’s obligations under the R&L Agreement.

As used in this Agreement, “Affiliate” means, with respect to a Shareholder, any corporation, limited liability company, partnership, or other business entity or any natural person controlled by, in control of, or under common control with that Shareholder.

Gentlemen:

(“LifeMap”) in connection with that certain Agreement and Plan of Merger (“Merger Agreement”), dated April 19, 2012, by and among BioTime, LifeMap, Xennex, Inc. (“Xennex”) and the stockholders of Xennex (“Stockholders”). We are providing this opinion at the request of BioTime and LifeMap pursuant to Section 4.2(f) of the Merger Agreement.

In our capacity as counsel to BioTime and LifeMap, we have examined originals or copies of originals of the following documents:

Articles of Incorporation of BioTime, as amended, as filed with the Secretary of State of California;

Bylaws, as amended, of BioTime;

Certificate of the Secretary of State of California as to the good standing of BioTime;

Articles of Incorporation of LifeMap, as amended, as filed with the Secretary of State of California;

Bylaws, as amended, of LifeMap;

Certificate of the Secretary of State of California as to the good standing of LifeMap;

The Merger Agreement and the schedules and exhibits thereto; and

Xennex, Inc.

In preparing this opinion:

(i) We have assumed the due authorization, execution and delivery of the Merger Agreement by Xennex and the Stockholders;

(ii) We have assumed the legal competency of all individual signers of documents.

(iii) We have assumed that all signatures of parties are genuine.

(iv) In those cases where we have examined copies of documents, we have assumed that those copies are complete and accurate and conform to the originals, and that the originals are genuine.

(v) We have assumed that there are no oral or written modifications of or amendments or supplements to the Merger Agreement and that there has been no waiver of any of the provisions of the Merger Agreement by action of the parties or otherwise.

(vi) We have relied on a Certificates of Good Standing from the Secretary of State of California with respect to the organization and existence of BioTime and LifeMap.

(vii) We have relied on (a) a certificate of the Secretary of BioTime as to certain matters, including copies of the Articles of Incorporation and Bylaws of BioTime that we reviewed, and resolutions adopted by the board of directors of BioTime with respect to the Merger Agreement; and (b) a certificate of officers of BioTime as to the incumbency of the officers who signed the Merger Agreement on behalf of BioTime;

Xennex, Inc.

May ___, 2012

Page 3

(ix) We have assumed that the Merger Agreement has been validly approved by the stockholders of Xennex, and that the Merger Agreement is the valid and binding agreement of Xennex and the Stockholders, and is enforceable against them in accordance with its terms; and

(x) We have reviewed and relied such other documents, matters, statutes, ordinances, published rules and regulations, published judicial and governmental decisions interpreting or applying the same, and other official interpretations as we deem applicable in connection with this opinion.

In reaching our opinions, we have made the inquiry of the officers of BioTime and LifeMap reflected in the Manager’s Certificate, but we have undertaken no other investigation or verification of such matters. In basing certain of our opinions on "our knowledge," the words "our knowledge" signify that, in the course of our representation of BioTime and LifeMap no facts have come to our attention that would give us actual knowledge or actual notice that any such opinions or other matters are not accurate. Further, the words "our knowledge" as used in this opinion are intended to be limited to the actual knowledge of the attorneys within our firm who have been directly involved in representing BioTime and LifeMap in connection with the Merger Agreement.

Based on the foregoing and subject to the assumptions and qualifications set forth in this letter, it is our opinion that:

1. Each of BioTime and LifeMap is a corporation duly organized, validly existing and in good standing under the laws of California.

2. The execution and delivery of the Merger Agreement, and the performance by BioTime and LifeMap of their respective obligations under this Agreement, have been duly authorized by all necessary action on the part of the Boards of Directors of BioTime and LifeMap. The Merger Agreement is the valid and binding agreement of BioTime or LifeMap, enforceable in accordance with its terms.

3. The execution and delivery of the Merger Agreement by BioTime and LifeMap do not violate any provisions of (i) any federal or state rule, regulation, statute, or law applicable to BioTime or LifeMap, (ii) the terms of any order, writ, or decree of any federal or state court or judicial or regulatory authority or body by which BioTime or LifeMap is bound and about which we have actual knowledge, or (iii) the Articles of Incorporation or Bylaws of BioTime or LifeMap.

Xennex, Inc.

4. The BioTime common shares, no par value, and the shares of LifeMap common stock, no par value, into which shares of Xennex capital stock will be converted upon consummation of the Merger, when issued in accordance with the Merger Agreement, will be duly authorized and validly issued, fully paid, and nonassessable.

5. To our knowledge, there is no action, proceeding, or investigation pending which challenges BioTime’s or Life Map’s right to enter into the Merger Agreement, or challenges any action taken or to be taken, by BioTime or LifeMap in connection with the Merger Agreement.

Our opinion as to the enforceability of the Merger Agreement is qualified in all respects by:

(a) limitations imposed by bankruptcy, insolvency, reorganization, arrangement, moratorium and other laws relating to or affecting the rights of creditors generally;

(b) limitations on rights to indemnification and contribution which may be imposed by applicable law, including the Securities Act of 1933, as amended, and applicable state securities laws, or equitable principles; and

(c) general principles of equity, regardless of whether such enforceability is considered in a proceeding at law or in equity.

We express no opinion as to the laws of any jurisdiction other than the laws of the State of California and the laws of the United States of America. The opinions expressed above concern only the effect of the laws (excluding the principles of conflict of laws) of the State of California and the United States of America as currently in effect. We assume no obligation to supplement this opinion if any applicable laws change after the date of this opinion, or if we become aware of any facts that might change the opinions expressed above after the date of this opinion.

The foregoing opinions are for the exclusive reliance of Xennex and the Stockholders.

	Very truly yours,
