Senior Stock: For purposes of Section 2 below, any class or series of shares of the Corporation that is entitled to receive dividends before any dividends are paid to the Series A Preferred Stock, and, for purposes of Section 3 below, any class or series of shares of the Corporation that is entitled to receive assets upon the liquidation, dissolution or winding up of the affairs of the Corporation before any assets are distributed to the Series A Preferred Stock.

2. Dividends.

(a) Subject to the prior preferences and other rights of any Senior Stock, but before payment of any dividends or other distributions to holders of Junior Stock (excluding dividends or other distributions to holders of Junior Stock payable exclusively in Junior Stock or rights to purchase Junior Stock), the holders of Series A Preferred Stock shall be entitled to receive, on a pari passu basis, a cumulative cash dividend in an amount equal to three percent (3%) of the Subscription Price per share, which shall be deemed accrued on June 30, and December 31 of each year regardless of whether declared by the Board of Directors. The dividend shall be paid, from funds legally available for such purpose, in two semi-annual installments on January 31 and July 31 of each year, or if such day is not a Business Day, on the next Business Day. Each such dividend shall be paid to the holders of record of the Series A Preferred Stock as their names appear on the share register of the Corporation on June 30, and December 31 of each year, as applicable, or, if a different date is designated by the Board of Directors with respect to the dividend payable, on the last Business Day immediately before the date on which the dividend is required to be paid.

(b) Any dividends or distributions declared and paid or distributed with respect to Junior Stock (other than dividends or distributions in shares of Junior Stock resulting in an adjustment to the Conversion Price under Section 4(g)) shall likewise be declared and paid or distributed to holders of Series A Preferred Stock such that all holders of Junior Stock and Series A Preferred Stock shall receive such dividends or distributions in proportion to the number of shares of Junior Stock that would be held by each such holder if all shares of Series A Preferred Stock were converted to Common Stock (or such other series of Junior Stock, if applicable) at the Conversion Price in effect as of the record date for the determination of holders of Common Stock entitled to receive such dividend or distribution (or such other series of Junior Stock, if applicable); provided that the Board of Directors shall set the same record date for the determination of holders of Series A Preferred Stock, Parity Stock, and Junior Stock entitled to receive such dividend or distribution.

3. Distributions Upon Liquidation, Dissolution or Winding Up.

(a) In the event of any voluntary or involuntary liquidation, dissolution or other winding up of the affairs of the Corporation, subject to the preferences and other rights of any Senior Stock, the holders of Series A Preferred Stock shall be entitled to be paid any dividends accrued pursuant to Section 2(a) but remaining unpaid. Such dividends shall be paid in cash. If the cash of the Corporation legally available for such distribution among the holders of the Series A Preferred Stock and any Parity Stock shall be insufficient to permit the payment to such holders of the full aforesaid preferential amount, then the entire amount legally available for distribution shall be distributed ratably among the holders of the Series A Preferred Stock and any Parity Stock in proportion to the full preferential amount that each such holder is otherwise entitled to receive under Section 2(a).

(b) Subject to the preferences and other rights of any Senior Stock, upon completion of the distribution required by subsection (a) of this Section 3, all of the remaining assets of the Corporation available for distribution to stockholders shall be distributed among the holders of Series A Preferred Stock, Parity Stock, and Common Stock in proportion to the number of shares of Common Stock that would be held by each such holder if all shares of Series A Preferred Stock and Parity Stock were converted into Common Stock at the applicable Conversion Price of Series A Preferred Stock and Parity Stock in effect as of the record date for the determination of holders of Common Stock entitled to receive such distribution; provided that the Board of Directors shall set the same record date for the determination of holders of Series A Preferred Stock, Parity Stock, and Common Stock entitled to receive such distribution.

(c) The (i) acquisition of the Corporation by another entity by means of any transaction or series of transactions (including, without limitation, any reorganization, merger or consolidation) in which the shareholders of the Corporation do not own a majority of the outstanding shares of the surviving or acquiring corporation upon completion of such transaction or series of transactions or (ii) a sale of all or substantially all of the assets of the Corporation shall be deemed a liquidation under this Section.

(d) The Corporation shall give each holder of record of Series A Preferred Stock written notice of an impending transaction deemed to be a liquidation under this Section not later than twenty (20) days prior to the shareholders’ meeting called to approve such transaction, or twenty (20) days prior to the closing of such transaction, whichever is earlier, and shall also notify such holders in writing of the final approval of such transaction. The first of such notices shall describe the material terms and conditions of the impending transaction, and the Corporation shall thereafter give such holders prompt notice of any material changes. The transaction shall in no event take place sooner than twenty (20) days after the Corporation has given the first notice provided for herein or sooner than ten (10) days after the Corporation has given notice of any material changes provided for herein; provided, however, that such periods may be shortened upon the written consent of the holders of Series A Preferred Stock that represent at least a majority of the then outstanding shares of Series A Preferred Stock.

(e) If the Corporation shall propose to take any action of the types described in Section 3(a) that will involve the distribution of assets other than cash, the notice described in subparagraph (d) above shall set forth a determination of the value (which may be an estimated value) of the assets to be distributed to the holders of shares of the Series A Preferred Stock, as determined in good faith by the Board of Directors of the Corporation.

4. Conversion Rights. The Series A Preferred Stock shall be convertible into Common Stock as follows:

(a) Conversion by Holder.

(i) Optional Conversion. Subject to and upon compliance with the provisions of this Section 4, and provided that an exemption from registration under the Securities Act of 1933, as amended, and an exemption from registration or qualification under applicable state securities or "blue sky" laws is then available, as determined in good faith by the Board of Directors, the Series A Preferred Stock shall be convertible at the election of the holder thereof, at any time and from time to time, into a number of fully paid and nonassessable shares of Common Stock determined in accordance with subparagraph (d) of this Section 4.

(b) Automatic Conversion. Each outstanding share of Series A Preferred Stock shall automatically be converted, without any further act of the Corporation or its shareholders, into fully paid and nonassessable Common Stock at the Conversion Price then in effect upon the earlier of:

(i) Automatic Conversion Date. March 4, 2019; or,

(ii) Vote. The holders of at least a majority of the outstanding shares of the Series A Preferred Stock, voting as a class, approve or consent to such conversion.

(c) Valid Issuance. All Common Stock which may be issued upon conversion of the Series A Preferred Stock will upon issuance by the Corporation be duly and validly issued, fully paid and nonassessable and free from all taxes, liens and charges with respect to the issuance thereof, and the Corporation shall take no action which will cause a contrary result.

(d) Number of Shares Issuable Upon Conversion. Each share of Series A Preferred Stock shall be converted into the number of shares of Common Stock determined by dividing (x) a number equal to the number of dollars and cents comprising the Subscription Price, by (y) a number equal to the number of dollars and cents comprising the Conversion Price in effect on the Conversion Date.

(i) Accrued But Unpaid Dividends. Upon the conversion of any Series A Preferred Stock, any accrued but unpaid dividends with respect to each such share shall be paid by the Corporation in cash, but any other dividends shall not be payable from and after the date of such conversion. A dividend shall be deemed accrued on June 30, and December 31 of each year for this purpose regardless of whether declared by the Board of Directors.

(e) Mechanics of Conversion. The holder of any Series A Preferred Stock may exercise the conversion right specified in paragraph (a) of this Section 4 by surrendering to the Secretary of the Corporation or any transfer agent of the Corporation the certificate or certificates for the shares to be converted, if such shares are certificated, accompanied by written notice specifying the number of shares to be converted. Upon the occurrence of the event specified in paragraph (b) of this Section 4, the outstanding Series A Preferred Stock shall be converted automatically without any further action by the holders of such shares and whether or not the certificates representing such shares are surrendered to the Corporation or its transfer agent. Conversion shall be deemed to have been effected on the date when delivery of notice of an election to convert and certificates for shares is made in the case of conversion under paragraph (a) of this Section 4, or on the date of the event specified in paragraph (b) of this Section 4, and such date is referred to herein as the "Conversion Date." Subject to the provisions of subparagraph (g)(ii) of this Section 4, as promptly as practicable thereafter (and after surrender of the certificate or certificates evidencing Series A Preferred Stock to the Corporation or any transfer agent of the Corporation, if applicable) the Corporation shall issue and deliver to or upon the written order of such holder a certificate or certificates for the number of shares of Common Stock to which such holder is entitled and a check or cash with respect to any fractional interest in any share of Common Stock as provided in paragraph (f) of this Section 4. Subject to the provisions of subparagraph (g)(ii) of this Section 4, the person in whose name the certificate or certificates for Common Stock are to be issued shall be deemed to have become a holder of record of such Common Stock on the applicable Conversion Date. Upon conversion of only a portion of the number of shares covered by a certificate representing Series A Preferred Stock surrendered for conversion (in the case of conversion pursuant to paragraph (a) of this Section 4), as applicable, the Corporation shall issue and deliver to or upon the written order of the holder of the certificate so surrendered for conversion, at the expense of the Corporation, a new certificate covering the number of shares of Series A Preferred Stock representing the unconverted portion of the certificate so surrendered, if such shares are to be held in certificated form. Notwithstanding the foregoing, the Corporation shall not be obligated to issue to any holder of Series A Preferred Stock certificates evidencing the Common Stock issuable upon such conversion unless certificates evidencing the Series A Preferred Stock are delivered to either the Corporation or any transfer agent of the Corporation if such shares of Series A Preferred Stock are held in certificated form.

(f) Fractional Shares. No fractional share of Common Stock or scrip shall be issued upon conversion of Series A Preferred Stock. If more than one share of Series A Preferred Stock shall be surrendered for conversion at any one time by the same holder, the number of shares of Common Stock issuable upon conversion thereof shall be computed on the basis of the aggregate number of shares of Series A Preferred Stock so surrendered. Instead of any fractional share of Common Stock which would otherwise be issuable upon conversion of any Series A Preferred Stock, the Corporation shall pay a cash adjustment in respect of such fractional interest in an amount equal to that fractional interest at the then Fair Value.

(g) Conversion Price Adjustments. If the Corporation shall (A) declare a dividend or make a distribution on its Common Stock in shares of Common Stock, (B) subdivide or reclassify the outstanding Common Stock into a greater number of shares, or (C) combine or reclassify the outstanding Common Stock into a smaller number of shares, the Conversion Price in effect at the time of the record date for such dividend or distribution or the effective date of such subdivision, combination or reclassification shall be proportionately adjusted so that the holder of any Series A Preferred Stock surrendered for conversion after such date shall be entitled to receive the number of shares of Common Stock which he would have owned or been entitled to receive had such Series A Preferred Stock been converted immediately prior to such date. Successive adjustments in the Conversion Price shall be made whenever any event specified above shall occur.

(i) Rounding of Calculations; Minimum Adjustment. All calculations under this Section 4(g) shall be made to the nearest cent or to the nearest one hundredth (1/100th) of a share, as the case may be. Any provision of this Section 4 to the contrary notwithstanding, no adjustment in the Conversion Price shall be made if the amount of such adjustment would be less than one percent (1%) of the Conversion Price, but any such amount shall be carried forward and an adjustment with respect thereto shall be made at the time of and together with any subsequent adjustment which, together with such amount and any other amount or amounts so carried forward, shall aggregate one percent (1%) of the Conversion Price or more. Notwithstanding the foregoing, the Board of Directors may elect at any time to make an adjustment otherwise required under this Section 4(g) of less than one percent (1%).

(ii) Timing of Issuance of Additional Common Stock Upon Certain Adjustments. In any case in which the provisions of this Section 4(g) require that an adjustment shall become effective immediately after a record date for an event, the Corporation may defer until the occurrence of such event (A) issuing to the holder of any Series A Preferred Stock converted after such record date and before the occurrence of such event the additional Common Stock issuable upon such conversion by reason of the adjustment required by such event over and above the Common Stock issuable upon such conversion before giving effect to such adjustment, and (B) paying to such holder any amount of cash in lieu of a fractional Common Share pursuant to paragraph (h) of this Section 4; provided that the Corporation upon request shall deliver to such holder a due xxxx or other appropriate instrument evidencing such holder's right to receive such additional shares, and such cash, upon the occurrence of the event requiring such adjustment.

(h) Fair Value. The “Fair Value” per share of Common Stock for any date shall be determined by the Board of Directors as follows:

(i) If the Common Stock is listed on a national securities exchange, the Fair Value shall be the average of the last reported sale price of the Common Stock on such exchange , for the last twenty consecutive trading days prior to such date; or

(ii) If the Common Stock is not listed on a national securities exchange but prices for the Common Stock are reported on the Nasdaq OTC Bulletin Board, the Fair Value shall be the average of the daily high and low sales prices reported on Nasdaq OTC Bulletin Board during the last twenty consecutive trading days prior to such date; or

(iii) If the prices for the Common Stock cannot be determined under Section 4(h)(i) or Section 4(h)(ii), the Fair Value shall be an amount determined in such reasonable manner as may be prescribed by the Board of Directors in good faith, irrespective of any accounting treatment.

(i) Statement Regarding Adjustments. Whenever the Conversion Price shall be adjusted as provided in paragraph (g) of this Section 4, the Corporation shall forthwith file, at the principal office of the Corporation, a statement showing in detail the facts requiring such adjustment and the Conversion Price that shall be in effect after such adjustment, and the Corporation shall also cause a copy of such statement to be sent by mail, first class postage prepaid, to each holder of Series A Preferred Stock at the address of such holder appearing on the Corporation's records. Where appropriate, such copy may be given in advance and may be included as part of a notice required to be mailed under the provisions of paragraph (j) of this Section 4.

(j) Notice to Holders. In the event the Corporation take any action resulting in an adjustment of the Conversion Price as provided in Section 4(g), the Corporation shall give notice to each holder of Series A Preferred Stock, in the manner set forth in paragraph (i) of this Section 4, which notice shall specify the adjustment of the Conversion Price and the effective date of such adjustment. Failure to give such notice, or any defect therein, shall not affect the legality or validity of any such action.

(k) Costs. The Corporation shall pay all documentary, stamp, transfer or other transaction taxes, if any, attributable to the issuance or delivery of Common Stock upon conversion of, any Series A Preferred Stock; provided that the Corporation shall not be required to pay any taxes which may be payable in respect of any transfer involved in the issuance or delivery of any certificate for such shares in a name other than that of the holder of the Preferred Stock in respect of which such shares are being issued.

(l) Reservation of Shares. So long as any Series A Preferred Stock remain outstanding, the Corporation shall reserve at all times free from preemptive rights, out of its authorized but unissued Common Stock, solely for the purpose of effecting the conversion of the Series A Preferred Stock, sufficient Common Stock to provide for the conversion of all outstanding Series A Preferred Stock; and if at any time the number of authorized but unissued shares of Common Stock shall not be sufficient to effect the conversion of all then outstanding shares of Series A Preferred Stock, the Corporation will take such corporate action as may, in the opinion of counsel, be necessary to increase its authorized but unissued shares of Common Stock to such number of shares as shall be sufficient for such purposes, including, without limitation, engaging in best efforts to obtain the requisite shareholder approval of any necessary amendment to, as applicable, this Certificate of Determination or the Corporation’s Articles of Incorporation, as may be amended in the future.

5. Voting Rights.

(a) In addition to the special voting rights provided in paragraph (b) of this Section 5 below and by applicable law, the holders of Series A Preferred Stock shall be entitled to vote upon all matters upon which holders of the Common Stock have the right to vote, or, if no Common Stock is issued and outstanding, all matters upon which holders of Common Stock would have the right to vote as a matter of law. The holders of Series A Preferred Stock shall also be entitled, notwithstanding any provision hereof, to notice of any shareholders’ meeting in accordance with the Bylaws of the Corporation. The holders of Series A Preferred Stock shall be entitled to cast the number of votes equal to the largest number of whole shares of Common Stock into which such Series A Preferred Stock could be converted pursuant to the provisions of Section 4 hereof at the record date for the determination of the shareholders entitled to vote on such matters, or, if no such record date is established, at the date such vote is taken or any written consent of shareholders is solicited. Such votes shall be counted together with votes of Common Stock and all other shares of capital stock having general voting powers, and shall not be counted separately as a class. In all cases where the holders of Series A Preferred Stock have the right (separately or together with holders of any other series of Preferred Stock of the Corporation) to vote separately as a class or as a series, such holders shall be entitled to one vote for each such share held by them respectively. Fractional votes shall not, however, be permitted and any fractional voting rights available on an as-converted basis (after aggregating all shares into which shares of Series A Preferred Stock held by each holder could be converted) shall be rounded to the nearest whole number (with one-half being rounded upward).

(b) The following matters shall require the approval of the holders of a majority of the Series A Preferred Stock then outstanding, voting as a separate class: (i) creation of any Preferred Stock ranking as Senior Stock to the Series A Preferred Stock with respect to the payment of dividends, liquidation preferences or voting rights; (ii) repurchase of any shares of Junior Stock except shares issued pursuant to or in connection with a compensation or incentive plan or agreement approved by the Board of Directors for any officers, directors, employees or consultants of the Corporation; (ii) any sale, conveyance, or other disposition of all or substantially all the Corporation's property or business, or any liquidation or dissolution of the Corporation, or a merger into or consolidation with any other corporation (other than a wholly-owned Subsidiary corporation), or any one or series of related transactions in which more than 50% of the voting power of the Corporation is disposed of, unless upon consummation of such transaction the holders of Series A Preferred Stock would receive a distribution on account of each share of Series A Preferred Stock an amount of cash or other property or both having a value (determined in accordance with Section 3(e)) at least equal to the value of any cash, property, or both to which holders of Common Stock would be entitled to receive, plus the amount of any accrued but unpaid dividends pursuant to Section 2(a); (iii) any adverse change in the rights, preferences and privileges of the Series A Preferred Stock; or (iv) any amendment of the Corporation's Articles of Incorporation, including this Resolution, or Bylaws that results in any adverse change in the rights, preferences or privileges of the Series A Preferred Stock; provided, that nothing in this paragraph shall restrict or limit the rights and powers of the Board of Directors to fix by resolution the rights, preferences, and privileges of, and restrictions and limitations on, stock ranking as Parity Stock or Junior Stock to Series A Preferred Stock.

6. Exclusion of Other Rights. Except as may otherwise be required by law, the Series A Preferred Stock shall not have any rights, preferences, privileges or restrictions other than those specifically set forth in this resolution and in the Corporation's Articles of Incorporation.

7. Headings of Subdivisions. The headings of the various subdivisions hereof are for convenience of reference only and shall not affect the interpretation of any of the provisions hereof.

8. Severability of Provisions. If any right, preference or limitation of the Series A Preferred Stock set forth in this resolution (as such resolution may be amended from time to time) is invalid, unlawful or incapable of being enforced by reason of any rule of law or public policy, all other rights, preferences and limitations set forth in this resolution (as so amended) which can be given effect without the invalid, unlawful or unenforceable right, preference or limitation shall, nevertheless, remain in full force and effect, and no right, preference or limitation herein set forth shall be deemed dependent upon any other such right, preference or limitation unless so expressed herein.

9. Status of Reacquired Shares. Shares of Series A Preferred Stock which have been issued and reacquired in any manner or which shall have been converted into Common Stock shall (upon compliance with any applicable provisions of the laws of the State of California) have the status of authorized and unissued Preferred Stock of the Corporation undesignated as to series and may be redesignated as to series and reissued.

10. Repurchases. With respect to the holders of Series A Preferred Stock, any repurchase by the Corporation of its outstanding Common Stock upon exercise of a repurchase option contained in an agreement between the Corporation and one or more of its employees, consultants, officers, directors, employee stock ownership plan trustees, or other persons having a business relationship with the Corporation shall be permissible, and each holder of Series A Preferred Stock consents to any such repurchases, regardless of any restrictions on such repurchase under Section 502, 503 or 506 of the California Corporations Code.

RESOLVED FURTHER, that the Chief Executive Officer, President, or any Vice President, and the Secretary or any Assistant Secretary of this Corporation be, and they hereby are, authorized and directed to execute, acknowledge, file and record a certificate of determination of preference in accordance with the foregoing resolution and the provisions of California law."

III. The number of shares of Series A Preferred Stock is 300,000. As of the date of this Certificate of Determination, no shares of Series A Preferred Stock have been issued.

We declare under penalty of perjury under the laws of the State of California that the matters set forth in this Certificate are true and correct of our own knowledge.

2. EXERCISE OF OPTION

(a) Mechanics of Exercise. Subject to the terms and conditions hereof (including, without limitation, the limitations set forth in Section 1(c) and Section 4), this Option may be exercised by the Purchaser at any time or times on or after the Effective Date, in whole or in part, subject to Section 1(c), by (i) delivery of a written notice, in the form attached hereto as Exhibit A (the "Exercise Notice"), duly completed and executed by Purchaser, stating Purchaser's election to exercise this Option, the number of shares of Series A Preferred Stock being tendered in exchange for LifeMap Shares upon exercise of this Option, and the number of LifeMap Shares being issued upon such exchange, and (ii) delivery of shares of Series A Preferred Stock, endorsed in blank, to the Company to be exchange for LifeMap Shares at the Exchange Ratio then in effect.

On or before the third (3rd) Trading Day following the date on which the Company has received the Exercise Notice, so long as the Purchaser delivers a number of shares of Series A Preferred Stock sufficient for such exercise at the Exchange Ratio (the “Aggregate Option Exchange Shares”) on or prior to the second (2nd) Trading Day following the date on which the Company has received the Exercise Notice (the "Share Delivery Date") (provided that if the Aggregate Option Exchange Shares have not been delivered by such date, the Share Delivery Date shall be one (1) Trading Day after the Aggregate Option Exchange Shares are delivered), the Company shall (X) provided that the Transfer Agent is participating in The Depository Trust Company ("DTC") Fast Automated Securities Transfer Program, credit such aggregate number of LifeMap Shares to which the Purchaser is entitled pursuant to such exercise to the Purchaser's or its designee's balance account with DTC through its Deposit / Withdrawal At Custodian system, or (Y) if the Transfer Agent is not participating in the DTC Fast Automated Securities Transfer Program, or if there is no Transfer Agent, issue and dispatch by overnight courier to the address as specified in the Exercise Notice, a certificate, registered in the name of the Purchaser or its designee, for the number of LifeMap Shares to which the Purchaser is entitled pursuant to such exercise. The Company shall be responsible for all fees and expenses of the Transfer Agent and all fees and expenses with respect to the transfer of LifeMap Shares to the Purchaser, if any.

The Company shall pay any and all taxes which may be payable with respect to the transfer of LifeMap Shares to the Purchaser upon exercise of this Option.

(b) Reissue of Stock Certificate. If the Purchaser delivers to the Company a number of shares of Series A Preferred Stock greater than the Aggregate Option Exchange Shares upon the exercise of this Option, the Company shall issue to Purchaser a replacement Series A Preferred Stock certificate for the number of shares of Series A Preferred Stock in excess of the Aggregate Option Exchange Shares.

(c) Company's Failure to Timely Deliver Securities. If the Company shall fail for any reason or for no reason to transfer to the Purchaser, or cause LifeMap to issue, on or prior to the Share Delivery Date, a certificate for the number of LifeMap Shares to which the Purchaser is entitled and cause such LifeMap Shares to be registered on LifeMap's share register or to credit the Purchaser's balance account with DTC for such number of LifeMap Shares to which the Purchaser is entitled upon the Purchaser's exercise of this Option, then, in addition to all other remedies available to the Purchaser, the Company (X) shall pay in cash to the Purchaser on each day after such third (3^rd) Trading Day that the transfer of such LifeMap Shares is not timely effected an amount equal to 1.5% of the product of (A) the sum of the number of LifeMap Shares not transferred to the Purchaser on a timely basis and to which the Purchaser is entitled and (B) the Closing Sale Price of the LifeMap Shares on the Trading Day immediately preceding the last possible date which the Company could have transferred such LifeMap Shares to the Purchaser without violating Section 2(a), or if the LifeMap Shares are then not traded on an Eligible Market, $4.00 (the “Designated Price”), and (Y) the Purchaser, upon written notice to the Company, may void its Exercise Notice with respect to, and retain or have returned, as the case may be, any shares of Series A Preferred Stock cancelled in connection with such voided exercise; provided that the voiding of an exercise shall not affect the Company's obligations to make any payments which have accrued prior to the date of such notice pursuant to this Section 2(c) or otherwise. In addition to the foregoing, if on or prior to the Share Delivery Date, the Company shall fail to transfer, or cause LifeMap to issue, a certificate to the Purchaser and cause the registration of such LifeMap Shares on LifeMap's share register or credit the Purchaser's balance account with DTC for the number of LifeMap Shares to which the Purchaser is entitled upon the Purchaser's exercise of this Option or pursuant to the Company's obligation pursuant to clause (ii) below, as applicable, and if on or after such Trading Day the Purchaser purchases (in an open market transaction or otherwise) LifeMap Shares to deliver in satisfaction of a sale by the Purchaser of LifeMap Shares issuable upon such exercise that the Purchaser anticipated receiving from the Company (a "Buy-In"), then the Company shall, within three (3) Trading Days after the Purchaser's request and in the Purchaser's discretion, either (i) pay cash to the Purchaser in an amount equal to the Purchaser's total purchase price (including brokerage commissions and other out-of-pocket expenses, if any) for the LifeMap Shares so purchased (the "Buy-In Price"), at which point the Company's obligation to deliver such certificate (and to transfer LifeMap Shares) or credit such Purchaser's balance account with DTC for such LifeMap Shares shall terminate, or (ii) promptly honor its obligation to deliver to the Purchaser a certificate or certificates representing such LifeMap Shares or credit such Purchaser's balance account with DTC and pay cash to the Purchaser in an amount equal to the excess (if any) of the Buy-In Price over the product of (A) such number of LifeMap Shares, times (B) the Closing Bid Price on the date of exercise. Nothing shall limit the Purchaser's right to pursue a decree of specific performance and/or injunctive relief with respect to the Company's failure to timely deliver certificates representing LifeMap Shares (or to electronically deliver such LifeMap Shares) upon the exercise of this Option as required pursuant to the terms hereof.

(d) Disputes. In the case of a dispute as to the determination of the Exchange Ratio or the arithmetic calculation of the LifeMap Shares, the Company shall promptly transfer to the Purchaser the number of LifeMap Shares that are not disputed and resolve such dispute in accordance with Section 12.

3. CERTAIN ADJUSTMENTS. The Exchange Ratio and the number of LifeMap Shares purchasable hereunder shall be adjusted from time to time as follows:

(a) Stock Splits, Combinations, Reclassifications and Other Changes in Common Stock. If LifeMap, at any time after the Effective Date, shall (A) pay a dividend in its Common Stock or make a distribution in Common Stock, (B) subdivide its outstanding Common Stock, (C) combine its outstanding Common Stock into a smaller number of shares, or (D) reclassify or change (including a change to the right to receive, or a change into, as the case may be, shares of stock, other securities, property, cash or any combination thereof) its Common Stock (including any such reclassification or change in connection with a consolidation or merger in which LifeMap is the surviving corporation), upon the exercise of this Option the Purchaser shall be entitled to receive from the Company the kind and number of LifeMap Shares or other securities of LifeMap or other property which the Purchaser would have owned or have been entitled to receive upon the happening of any of the events described above, had this Option been exercised at the Exchange Ratio immediately prior to the happening of such event or any record date with respect thereto.

(b) Distribution of Options, Warrants, Warrants, Rights, and Convertible Securities or Other Assets. If LifeMap at any time after the Effective Date, shall distribute to all holders of its Common Stock (including any distribution made in connection with a merger in which LifeMap is the surviving corporation) (i) rights, options or warrants, or convertible or exchangeable securities containing the right to subscribe for or purchase Common Stock, or (ii) evidences of its indebtedness or assets, including cash but excluding Ordinary Cash Dividends (as defined below), then in each case with respect to each LifeMap Share issued upon the exercise of this Option, the Purchaser shall also receive from the Company either (a) the portion of the subscription rights, options or warrants, or convertible or exchangeable securities (or securities issued upon the conversion of convertible securities) or assets or evidences of indebtedness so distributed to the Company applicable to one LifeMap Share, or (b) the then fair value of the securities described in (a) as determined in good faith by the Board of Directors of the Company whose determination shall be conclusive; provided, that the Company need not deliver any subscription rights, options or warrants that shall have expired by their terms. The Company shall determine whether to deliver the consideration described in clause (a) or clause (b) of the preceding sentence upon the exercise of this Option. A cash dividend shall be deemed an “Ordinary Cash Dividend” for purposes of this Option if the dividend is paid out of consolidated earnings or earned surplus and is declared by the Board of Directors of LifeMap to be a regular or ordinary quarterly, semi-annual or annual dividend.

4. RESTRICTIONS ON TRANSFER.

(a) Transfer. This Option is personal to the Purchaser and may not be sold, transferred or assigned, except (i) to a successor in interest of the Purchaser as a result of any consolidation of the Purchaser with or merger of the Purchaser into another Person, (ii) to another Purchaser (as defined in the Securities Purchase Agreement) or (iii) to another Person as part of a sale of all or substantially all the property of the Purchaser to such other Person.

(b) Restrictions on Transfer of LifeMap Shares.

(i) Any LifeMap Shares issued to Purchaser upon the exercise of this Option, may not be sold, pledged, hypothecated, transferred or assigned, in whole or in part, unless (A) a registration statement under the Securities Act and under any applicable state securities laws is effective therefor or (B) an exemption from such registration is then available and an opinion of counsel, reasonably acceptable to LifeMap and the Transfer Agent, if any, has been rendered stating that such sale, pledge, hypothecation, transfer or assignment will not violate the Securities Act. Notwithstanding anything to the contrary contained herein (x) the LifeMap Shares may be pledged in connection with a bona fide margin account or other loan or financing arrangement secured by the securities and no legal opinion shall be required therefor and (y) no representation, warranty, covenant or opinion shall be required for the sale, pledge, hypothecation, transfer or assignment of any LifeMap Shares if a registration statement with respect to the resale of such LifeMap Shares is effective at the time of any such sale, pledge, hypothecation, transfer or assignment.

(ii) As a condition precedent to the registration of transfer of any certificates representing LifeMap Shares upon the exercise of this Option or transfer of LifeMap Shares, the Company and LifeMap shall be entitled to obtain a letter or other instrument from the Purchaser containing such covenants, representations or warranties by such Purchaser similar to those contained in this Section 4 as reasonably deemed necessary by the Company or LifeMap to effect compliance by the Company or LifeMap with the requirements of the Securities Act and any other applicable federal and/or state securities laws.

(iii) Any sale, pledge, hypothecation, transfer, or assignment of this Option or LifeMap Shares in violation of the foregoing restrictions shall be deemed null and void and of no binding effect.

(iv) The Company will, and will request that LifeMap will, issue instructions to any Transfer Agent and registrar of the Common Stock to refuse to register the transfer of any LifeMap Shares not made pursuant to registration under the Securities Act and applicable state securities laws, or pursuant to an available exemption from registration under the Securities Act and applicable state securities laws.

(v) The LifeMap Shares shall bear an appropriate legend, conspicuously disclosing the restrictions on transfer, under this Section 4, until the same are registered for sale under the Securities Act or are transferred in a transaction exempt from registration under the Securities Act entitling the transferee to receive securities that are not deemed to be “restricted securities” as such term is defined in Rule 144 under the Securities Act. The Company agrees that upon the sale of LifeMap Shares pursuant to a registration statement or an exemption entitling the transferee to receive securities that are not deemed to be “restricted securities,” or at such time as registration under the Securities Act shall no longer be required, upon the presentation of the certificates containing such a legend to the transfer agent or warrant agent, if any, it will request removal of such legend; provided, that unless the request for removal of the legend is in connection with a sale registered under the Securities Act, the Purchaser shall have provided an opinion of counsel, acceptable to the Company and the Transfer Agent to the effect that such legend may be removed in compliance with the Securities Act.

(c) Investment Representations. Each Purchaser makes the following representations, severally and not jointly and severally, in connection with its acquisition of this Option and any LifeMap Shares upon the exercise of this Option:

(i) Purchaser has made such investigation of LifeMap as Purchaser deemed appropriate for determining to acquire (and thereby make an investment in) this Option and LifeMap Shares, and in making such investigation Purchaser has had access to such financial and other information concerning LifeMap as Purchaser requested. Purchaser is relying on the information communicated to Purchaser in writing by LifeMap or the Company. Purchaser has not relied on any statement or representations inconsistent with those communicated to Purchaser in writing by LifeMap or the Company. Purchaser has had a reasonable opportunity to ask questions of and receive answers from the executive officers of LifeMap and the Company concerning LifeMap, and to obtain additional information, to the extent possessed or obtainable by LifeMap or the Company without unreasonable effort or expense, necessary to verify the information communicated or provided to Purchaser. All such questions have been answered to Purchaser’s satisfaction.

(ii) Purchaser is acquiring this Option and upon exercise of this Option will purchase LifeMap Shares solely for Purchaser's own account, and Purchaser has no direct or indirect arrangement or understandings with any other persons to distribute or regarding the distribution of the LifeMap Shares or this Option; provided, that this representation and warranty shall not prohibit Purchaser from selling LifeMap Shares in the ordinary course of business pursuant to a registration statement under the Securities Act or otherwise in compliance with the Securities Act and applicable state securities or “blue sky” laws.

(iii) Purchaser is an “accredited investor” as defined in Rule 501 under the Securities Act.

(iv) Purchaser, either alone or together with its representatives, has such knowledge, sophistication and experience in business and financial matters so as to be capable of evaluating the merits and risks of the prospective investment in this Option and LifeMap Shares, and has so evaluated the merits and risks of such investment. Such Purchaser is able to bear the economic risk of an investment in this Option and LifeMap Shares and, at the present time, is able to afford a complete loss of such investment.

5. REGISTRATION RIGHTS. The Company hereby covenants and agrees that in the event the Company receives any registration rights from LifeMap in respect of any LifeMap Shares owned by the Company, simultaneously with the exercise of any such registration rights at any time that this Option remains exercisable in whole or in part, the Company shall cause LifeMap to register all of the LifeMap Shares issuable to the Purchaser as of the applicable date of determination pursuant to the terms of this Option. The Company acknowledges and agrees that prior to excluding any LifeMap Shares from any registration statement, it shall first exclude all other LifeMap Shares owned by the Company other than any LifeMap Shares that are subject to an option provided to another Purchaser (as defined in the Securities Purchase Agreement) which shall be subject to exclusion on a pro rata basis with all other Purchasers (as defined in the Securities Purchase Agreement). The Company shall do and perform, or cause to be done and performed, all such further acts and things, and shall execute and deliver all such other agreements, certificates, instruments and documents, including, without limitation, any assignment of any registration rights with respect to the Common Stock purchasable pursuant to this Option granted to the Company under any registration rights agreement by LifeMap and the Company or under any registration statement, as Purchaser may reasonably request in order to carry out the intent and accomplish the purposes of this Section 5.

6. NONCIRCUMVENTION. The Company hereby covenants and agrees that the Company will not, by amendment of its Articles of Incorporation, Bylaws, or through any reorganization, transfer of assets, consolidation, merger, scheme of arrangement, dissolution, issue or sale of securities, or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Option, and will at all times in good faith carry out all the provisions of this Option and take all action as may be required to protect the rights of the Purchaser. Without limiting the generality of the foregoing, the Company shall continue to hold a sufficient number of LifeMap Shares to permit Purchaser to exercise this Option in full. The Company will, and will request that LifeMap will, issue instructions to any Transfer Agent and registrar of the Common Stock to refuse to register the transfer of any LifeMap Shares in violation of the immediately preceding sentence.

7. PURCHASER NOT DEEMED A LIFEMAP SHAREHOLDER. The Purchaser, solely in such Person's capacity as the holder of this Option, shall not be entitled to vote or receive dividends or be deemed the holder of share capital of LifeMap for any purpose, nor shall anything contained in this Option be construed to confer upon the Purchaser, solely in such Person's capacity as the holder of this Option, any of the rights of a shareholder of LifeMap or any right to vote, give or withhold consent to any corporate action (whether any reorganization, issue of stock, reclassification of stock, consolidation, merger, conveyance or otherwise), receive notice of meetings, receive dividends or subscription rights, or otherwise, prior to the purchase of the LifeMap Shares through the due exercise of this Option. In addition, nothing contained in this Option shall be construed as imposing any liabilities on the Purchaser to purchase any securities or as a shareholder of the Company or LifeMap (other than upon exercise of this Option), whether such liabilities are asserted by the Company or LifeMap or by their respective creditors. Notwithstanding this Section, the Company shall provide the Purchaser with copies of such notices and other information given to the Common Stock holders of LifeMap generally, promptly after receipt thereof by the Company, unless the Company believes that such information is material, nonpublic information regarding the Company or LifeMap.

10. GOVERNING LAW; JURISDICTION. This Option shall be governed by and construed and enforced in accordance with, and all questions concerning the construction, validity, interpretation and performance of this Option shall be governed by, the internal laws of the State of California, without giving effect to any choice of law or conflict of law provision or rule (whether of the State of California or any other jurisdictions) that would cause the application of the laws of any jurisdictions other than the State of California. The Company and the Purchaser hereby irrevocably submit to the non-exclusive jurisdiction of the state and federal courts sitting in the City of New York and the County of Alameda and the United States District Court for the Northern District of California for the adjudication of any dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein, and hereby irrevocably waives, and agrees not to assert in any suit, action or proceeding, any claim that it is not personally subject to the jurisdiction of any such court, that such suit, action or proceeding is brought in an inconvenient forum or that the venue of such suit, action or proceeding is improper.

11. CONSTRUCTION; HEADINGS. This Option shall be deemed to be jointly drafted by the Company and Purchaser and shall not be construed against any Person as the drafter hereof. The headings of this Option are for convenience of reference and shall not form part of, or affect the interpretation of, this Option.

12. DISPUTE RESOLUTION. In the case of a dispute as to the determination of the Exchange Ratio or the arithmetic calculation of the LifeMap Shares purchasable upon the exercise of this Option, the Company shall submit the disputed determinations or arithmetic calculations via facsimile within two (2) Business Days of receipt of the Exercise Notice giving rise to such dispute, as the case may be, to the Purchaser. If the Purchaser and the Company are unable to agree upon such determination or calculation of the Exchange Ratio or the LifeMap Shares within three (3) Business Days of such disputed determination or arithmetic calculation being submitted to the Purchaser, then the Company shall, within two (2) Business Days submit via facsimile (a) the disputed determination of the Exchange Ratio to an independent, reputable investment bank selected by the Company and approved by the Purchaser or (b) the disputed arithmetic calculation of the LifeMap Shares to the Company's independent, outside accountant. The Company shall cause at its expense the investment bank or the accountant, as the case may be, to perform the determinations or calculations and notify the Company and the Purchaser of the results no later than ten (10) Business Days from the time it receives the disputed determinations or calculations. Such investment bank's or accountant's determination or calculation, as the case may be, shall be binding upon all parties absent demonstrable error.

13. REMEDIES, OTHER OBLIGATIONS, BREACHES AND INJUNCTIVE RELIEF. The remedies provided in this Option shall be cumulative and in addition to all other remedies available under this Option, at law or in equity (including a decree of specific performance and/or other injunctive relief), and nothing herein shall limit the right of the Purchaser to pursue actual damages for any failure by the Company to comply with the terms of this Option.

14. SEVERABILITY. If any provision of this Option is prohibited by law or otherwise determined to be invalid or unenforceable by a court of competent jurisdiction, the provision that would otherwise be prohibited, invalid or unenforceable shall be deemed amended to apply to the broadest extent that it would be valid and enforceable, and the invalidity or unenforceability of such provision shall not affect the validity of the remaining provisions of this Option so long as this Option as so modified continues to express, without material change, the original intentions of the parties as to the subject matter hereof and the prohibited nature, invalidity or unenforceability of the provision(s) in question does not substantially impair the respective expectations or reciprocal obligations of the parties or the practical realization of the benefits that would otherwise be conferred upon the parties.
