To Purchase Common Stock of

M3 BIOTECHNOLOGY, INC.

Date of Issuance: 08 April 2013

The following is a statement of the rights of the holder of this Warrant and the conditions to which this Warrant is subject, and to which the holder hereof, by the acceptance of this Warrant, agrees:

For value received, M3 BIOTECHNOLOGY, INC., a Washington Corporation (the “Company”), hereby grants to the ALZHEIMER’S DRUG DISCOVER FOUNDATION, a public foundation organized in New York (“ADDF”), and its registered assigns (the “Holder”), the right to purchase from the Company at the Exercise Price of the lesser of $1 per share or the first price per share of the Company’s stock negotiated in an arms-length transaction with a bona-fide third party totaling at least $250,000 (the “Exercise Price”) a number of shares (the “Issuable Shares”) of common stock of the Company (the “Common Stock”) equal to the number of shares of Common Stock which, when multiplied by the Exercise Price, equals the first tranche of the principal amount of the Convertible Promissory Note signed in conjunction with this Warrant $87,497 multiplied by 0.30.  Such Exercise Price is referred to herein as the “Exercise Price”.  This Warrant may be exercised at any time prior to the eight (8)-year anniversary of its issuance (the “Expiration Date”).

This Warrant is issued under the terms of that certain Agreement to Accept Conditions for Biotechnology Funding, dated 08 April 2013.

1.Warrant Not Registered.

The Holder of this Warrant acknowledges that neither this Warrant nor the Issuable Shares have been registered under the Act, and agrees not to sell, pledge, distribute, offer for sale, transfer or otherwise dispose of this Warrant or any Issuable Shares in the absence of (i) an effective registration statement under the Act as to this Warrant or such Issuable Shares and registration or qualification of this Warrant or such Issuable Shares under any applicable U.S. federal or state securities law then in effect or (ii) an opinion of counsel, satisfactory to the Company, that such registration and qualification are not required.  Each certificate or other instrument evidencing the issuable Shares shall bear a legend substantially to the foregoing effect.

2.Exercise of Warrant.

2.1(a)The Warrant may be exercised at any time prior to the Expiration Date upon (i) surrender to the Company at the main office of the Company (or such other office or agency of the Company as it may be designate in writing to the Holder at the address of the Holder appearing on the books of the Company) of the warrant certificates, together with the Notice of Exercise annexed hereto properly completed and executed by the Holder and (ii) payment to the Company of the Exercise Price for each Share or other securities issuable upon exercise of such Warrant.  The Exercise Price may be paid (i) in cash or by certified or official bank check or by wire transfer to an account designated by the Company for such purpose (a “Cash Exercise”) or (ii) without the payment of cash, by reducing the number of Issuable Shares that would be obtainable upon the exercise of the Warrant and payment of the Exercise Price in cash so as to yield a number of Issuable Shares upon the exercise of such Warrant equal to the product of (x) the number of Issuable Shares for which such Warrant is exercisable as of the date of exercise (if the Exercise Price were being paid in cash) and (y) the Cashless Exercise Ratio (as defined below).  An exercise of the Warrant in accordance with clause (ii) of the immediately preceding sentence is herein called a “Cashless Exercise.”

(b)In the event of a Cashless Exercise of the Warrant, the Company will purchase from the Holder such portion of the Warrant as would have entitled the Holder to receive the excess of the number of Common Stock deliverable upon a Cash Exercise over the number of Common Stock deliverable upon Cashless Exercise, for a Exercise Price equal to the Exercise Price multiplied by the excess of the number of Common Stock purchasable upon a Cash Exercise.  The Company agrees to and shall offset the Exercise Price referred to in the immediately preceding sentence with the obligation to pay the Exercise Price in respect of the Common Stock deliverable upon a Cashless Exercise.  Upon surrender of the warrant certificate in connection with the Holder’s option to elect a Cashless Exercise, the number of Common Stock deliverable upon a Cashless Exercise shall be equal to the number of Common Stock issuable upon the exercise of Warrant that the Holder specifies are to be exercised pursuant to a Cashless Exercise multiplied by the Cashless Exercise Ratio.  All provisions of this Warrant shall be applicable with respect to the surrender of a warrant certificate pursuant to a Cashless Exercise for less than the full number of Warrants represented thereby.  Upon surrender of the warrant certificate and payment of the Exercise Price in accordance with this Warrant, the Company will issue Common Stock of the Company for the portion of the Warrant exercised, subject to adjustment as described herein.  Whenever there occurs a Cashless Exercise, the Company shall deliver to the Holder a certificate setting forth the Cashless Exercise Ratio.

-2-

(c)“Cashless Exercise Ratio” means a fraction, the numerator of which is the amount by which the Current Market Value (as defined below) per Share on the exercise date of the Warrant exceeds the Exercise Price per Share as of such exercise date and the denominator of which is the Current Market Value per Share on the exercise date.

(d)“Current Market Value” per Share means:

(i)if the Common Stock are not registered under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) the fair market value of the Common Stock (without any discount for lack of liquidity, the amount of such Common Stock offered to be purchased or the fact that the Common Stock may represent a minority interest in a private company or a company under the control of another person) as determined in good faith by the Board of Directors of the Company and certified in a board resolution that is delivered to the Holder, and, if requested by the Holder, determined to be fair, from a financial point of view, to the Holder, by an independent financial expert (as set forth in such independent financial expert’s written fairness opinion); or

(ii)if the Common Stock are registered under the Exchange Act, the average of the last reported sale price of the security (or the equivalent in an over-the-counter market) for each business day during the period commencing 15 business days before such date and ending on the date one day prior to such date, or if the Common Stock have been registered under the Exchange Act for less than 15 consecutive business days before such date, the average of the daily closing bid prices (or such equivalent) for all of the business days before such date for which daily closing bid prices are available (provided, however, that if the closing bid price is not determinable for at least 10 business days in such period, the “Current Market Value” of the security shall be determined as if the security were not registered under the Exchange Act).  The Company shall pay the fees and expenses of any independent financial expert in the determination of Current Market Value.

2.2Certificates or other documentation evidencing the Issuable Shares purchased hereunder shall be delivered to the Holder within a reasonable period of time after the later of (i) the date on which this Warrant is exercised, or (ii) the date on which the Exercise Price is full paid, but in no event shall they be delivered later than 15 days following such date.

2.3The Company covenants and agrees that all Issuable Shares which may be issued upon the exercise of this Warrant will be duly authorized, validly issued, fully paid and nonassessable and free from all taxes, liens, encumbrances, and charges in respect of the issue thereof (other than taxes in respect of any transfer occurring contemporaneously with such issue).

2.4The Company further covenants and agrees that, during the period within which the rights evidenced by this Warrant may be exercised, the Company will at all times during such period have authorized and reserved, for the purpose of issue or transfer upon exercise of the rights evidenced by this Warrant, a sufficient number of authorized by unissued Common Stock, or other securities and property, when and as required to provide for the exercise of the rights evidenced by this Warrant.  The Company will take all such action as may be necessary to assure that such Common Stock may be issued as provided herein without violation of any applicable law or regulation, or of any requirements of any securities exchange upon which the securities of the Company may be listed; provided, however, that the Company shall not be required to effect a registration under federal or state securities laws with respect to such exercise.

3.Adjustment of Exercise Price.

3.1The Exercise Price and the number of Issuable Shares are subject to adjustment in accordance with this Section 3 from time to time upon the occurrence of certain events described in this Section 3.

3.2In the event the Company shall, at any time or from time to time after the date hereof, issue any Common Stock as a stock dividend to the holders of Common Stock, or subdivide or combine the outstanding Common Stock into a greater or lesser number of shares, or effectuate a similar sale, issuance, subdivision or combination in which no consideration is payable by the holders of Common Stock (any such sale, issuance, subdivision or combination being herein called a “Share Change”), then, and thereafter upon each further Share Change, the Exercise Price shall be adjusted in inverse proportion to the fraction determined by dividing the number of shares of Stock outstanding after such event (on a fully diluted basis) by the number of shares of Common Stock outstanding be fore such event (on a fully diluted basis) (the “Adjustment Ratio”) and the number of Issuable Shares shall be adjusted in direct proportion to the Adjustment Ratio.

3.3If the  Company shall at any time issue or sell any Common Stock or equity securities convertible into or exchangeable for Common Stock (“Share Equivalents”) where the then effective price per Share of stock (consisting of the amount per Share paid upon issuance of the securities plus, if applicable, any amount per Share payable upon conversion or exchange) (the “Effective Share Price”) is less than the then-effective Exercise Price, or if the terms of any then existing securities provide for, or are amended to effect, a reduction in the Effective Share Price to a price less than the then effective Exercise Price, then the then effective Exercise Price shall concurrently with such issuance, sale or amendment be reduced to the Effective Share Price.

3.4For purposes of this Section 3, the number of Common Stock and Share Equivalents outstanding at any given time shall include Common Stock and Share Equivalents owned or held by or for the account of the Company.

3.5(a)If the Company shall be party to a Sale or Merger or an IPO (as defined below), or engage in any similar transaction, the, in each case, in lieu of the Common Stock issuable upon the exercise of the Warrant immediately prior to such transaction, upon the consummation of such transaction at the option of the Holder, either (A) the Warrant shall terminate, or (B) the Holder shall receive the stock and/or other securities and/or property (including cash) to which the Holder would have been entitled (less the then effective Exercise Price) upon such Sale or Merger or similar transaction had the Holder exercised the Warrant fully immediately prior thereto, all subject to the adjustments provided herein or substantially similar adjustments.

(b)A “Sale or Merger” shall mean any of the following: (i) the merger or consolidation of the Company into or with another entity in which the holders of the voting equity of the Company immediately preceding such merger or consolidation shall own less than fifty percent (50%) of the voting securities of the surviving entity; (ii) the sale, transfer or lease, whether in a single transaction or pursuant to a series of related transactions or plan, of all or substantially all the assets of the Company which assets shall include for these purposes fifty percent (50%) or more of the

-4-

outstanding voting equity securities of any subsidiaries of the Company, the assets of which constitute all or substantially all the assets of the Company and its subsidiaries taken as a whole; (iii) the sale, transfer, or lease, whether in a single transaction or pursuant to a series of related transactions, of all or substantially all the assets of the subsidiaries of the Company, the assets of which constitute all or substantially all of the assets of the Company and such subsidiaries taken as a whole, (iv) a sale or transfer, whether in a single transaction or series of related transactions, of fifty percent (50%) or more of the Company’s outstanding voting securities other than in a financing transaction or (v) a public offering of the securities of the Company.

3.6In the event the Company at any time or from time to time makes, or fixes a record date for the determination of holders of Common Stock entitled to receive, any distribution payable in securities or assets of the Company other than Common Stock and other than as otherwise adjusted for in this Section 3, then and in each such event provision shall be made so that the Holder shall receive upon exercise of the Warrant, in addition to the number of Common Stock receivable thereupon, the amount of securities or assets of the Company which the Holder would have received had the Warrant been converted into Common Stock on the date of such event and had it thereafter, during the period from the date of such event to and including the date of conversion, retained such securities receivable by it as aforesaid during such period, subject to all other adjustments called for during such period under this Section 3.

3.7The Company shall notify the Holder in writing at least twenty (20) days’ prior to the occurrence of any event requiring any adjustment as provided herein, which notice shall set forth in reasonable detail such event, the amount of the adjustment and method of calculation thereof.  At any time and from time to time if any reorganization, reclassification, recapitalization, stock dividend, stock split, stock combination, transfer or lease of substantially all assets, issuance or sale of securities or other event shall occur as to which the provisions of this Section 3 are not strictly applicable, but the failure to make any adjustment would not fairly protect the rights of the Holder in accordance with the essential intent and principles hereof, then, in each such case, the number of Issuable Shares and the Exercise Price shall be appropriately adjusted to preserve, without dilution, the purchase rights represented by this Warrant and to place the Holder in an equivalent economic position as it would have been in had such events not occurred.  If at any time, the Company issues, or otherwise provides for or grants, rights to acquire Common Stock or securities convertible into or exchangeable for Common Stock that provide for greater or more favorable antidilution protection than the antidilution protection provided for herein (including, but not limited to, rights with respect to the events that trigger the adjustment or the formula pursuant to which any such adjustment is made), the Company shall notify the Holder of such issuance, provision or grant within ten business days of such event and this Warrant shall be deemed automatically amended as of the date of the issuance, provision or grant of such rights or convertible securities or protections, as the case may be, so that the Holder shall receive the benefit of such greater antidilution protection.  The Company will not, by amendment of its Certificate of Incorporation or through any reorganization, transfer of assets, consolidation, merger, 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 to be observed or performed hereunder by the Company but will at all times in good faith assist in the carrying out of all the provisions in this Section 3 and in the taking of all such action as may be necessary or appropriate in order to protect the rights of the holders of the Warrant against impairment.]

-5-

4.No Fractional Common Stock.

The Company shall not be required to issue any fractional shares in connection with any exercise of this Warrant.  The Company may pay to the Holder, in lieu of issuing any fractional share, a sum in cash equal to such fraction multiplied by the then effective Exercise Price.

5.Charges, Taxes and Expenses.

Issuance of certificates or other documentation evidencing the Issuable Shares shall be made without charge to the Holder for any issue or transfer tax or other incidental expense in respect of the issuance of such certificate, all of which taxes and expenses shall be paid by the Company, and such certificates shall be issued in the name of the Holder or in such name or names as may be directed by the Holder; provided, however, that in the event certificates or other documentation evidencing the Common Stock are to be issued in a name other than the name of the Holder, this Warrant, when surrendered for exercise, shall be accompanied by the Assignment Form attached hereto duly executed by the Holder; and provided, further, that upon any transfer involved in the issuance or delivery of any certificates or other documentation evidencing the Issuable Shares the Company may require reimbursement for any tax imposed in connection with such transfer.

6.No Rights as Shareholder.

This Warrant does not entitle the Holder to any voting rights or other rights as a shareholder of the Company prior to the exercise hereof.

7.Exchange and Registry of Warrant.

This Warrant is exchangeable, under the surrender hereof by the Holder at the above-mentioned office or agency of the Company, for a new Warrant of like tenor and dates as of such exchange.  The Company shall maintain at such office or agency a registry showing the name and address of the Holder.  This Warrant may be surrendered for exchange, transfer or exercise, in accordance with its terms, at such office of agency of the Company, and the Company shall be entitled to rely in all respects, prior to written notice to the contrary, upon such registry.

8.Loss, Theft, Destruction or Mutilation of Warrant.

Upon receipt by the Company of evidence reasonably satisfactory to it of the loss, theft, destruction or mutilation of this Warrant, and in case of loss, theft or destruction, of indemnity or security reasonably satisfactory to it, and upon reimbursement to the Company of all reasonable expenses incidental thereto, and upon surrender and cancellation of such Warrant, if mutilated, the Company will make and deliver a new Warrant of like tenor and dated as of such cancellation, in lieu of this Warrant.  The foregoing notwithstanding, with respect to the initial Holder of this Warrant, the Company in lieu of its rights set forth in the preceding sentence, shall only require an affidavit of loss and indemnity agreement from such Holder and such Holder shall not be obligated to provide any security therefore or to pay any fees or expenses in connection therewith.
