THE SHARES ISSUABLE HEREUNDER ARE SUBJECT TO (1) RESTRICTIONS ON TRANSFERABILITY AND RESALE, INCLUDING A LOCK-UP PERIOD OF UP TO 180 DAYS (SUBJECT TO CERTAIN EXTENSIONS) IN THE EVENT OF AN INITIAL PUBLIC OFFERING, AS SET FORTH IN AN INVESTOR RIGHTS AGREEMENT, AND (2) VOTING RESTRICTIONS AS SET FORTH IN A VOTING AGREEMENT, COPIES OF WHICH MAY BE OBTAINED AT THE PRINCIPAL OFFICE OF THE COMPANY.

THIS WARRANT CERTIFIES THAT, for good and valuable consideration, LIFE SCIENCE LOANS, LLC (together with any successor or permitted assignee or transferee of this Warrant or of any shares issued upon exercise hereof, “Holder”) is entitled to purchase up to such number of fully paid and non-assessable shares of the above-stated class and series of stock (the “Class”) of the above-named company (the “Company”) as determined pursuant to Paragraph A below, at the above-stated Warrant Price, all as set forth above and as adjusted pursuant to Article 2 of this Warrant, subject to the provisions and upon the terms and conditions set forth in this Warrant.

A. Number Shares. On and as of the date of the Second Term Loan A Advance (as defined in the Loan Agreement) made to the Company, this Warrant automatically shall become exercisable for such number of shares of the Class as shall equal (i)(a) 0.015, multiplied by (b) the amount of such Second Term Loan A Advance, divided by (ii) the Warrant Price in effect on and as of the date of such Second Term Loan A Advance, subject to adjustment thereafter from time to time in accordance with the provisions of this Warrant (the “Second Term Loan A Advance Shares”). On and as of the date of the Second Term Loan B Advance (as defined in the Loan Agreement) made to the Company, this Warrant automatically shall become exercisable for an additional number of shares of the Class as shall equal (i)(a) 0.015, multiplied by (b) the amount of such Second Term Loan B Advance, divided by (ii) the Warrant Price in effect on and as of the date of such Second Term Loan B Advance, subject to adjustment thereafter from time to time in accordance with the provisions of this Warrant (the “Second Term Loan B Advance Shares”). The Second Term Loan A Advance Shares and the Second Term Loan B shall be referred to below cumulatively as the “Shares”.

1.1 Method of Exercise. Holder may at any time and from time to time exercise this Warrant, in whole or in part, by delivering to the Company the original of this Warrant together with a duly executed Notice of Exercise in substantially the form attached hereto as Appendix 1 and, unless Holder is exercising the conversion right set forth in Article 1.2, a certified or bank check, wire transfer of same-day funds (to an account designated by the Company), or other form of payment acceptable to the Company for the aggregate Warrant Price for the Shares being purchased.

1.2 Conversion Right. In lieu of exercising this Warrant as specified in Article 1.1, Holder may from time to time convert this Warrant, in whole or in part, upon delivery to the Company of the original of this Warrant together with a duly executed Notice of Exercise in substantially the form attached hereto as Appendix 1, into a number of Shares determined as follows:


	X = Y(A-B)/A

where:

	X =	the number of Shares to be issued to the Holder;

	Y =	the number of Shares with respect to which this Warrant is being exercised;

	A =	the Fair Market Value (as determined pursuant to Article 1.3 below) of one Share; and

	B =	the Warrant Price.

1.3 Fair Market Value. If the Company’s common stock is then traded or quoted on a nationally recognized securities exchange, inter-dealer quotation system or over-the-counter market (a “Trading Market”) and the Class is common stock, the fair market value of a Share shall be the closing price or last sale price of a share of common stock reported for the business day immediately before the date on which Holder delivers this Warrant together with its Notice of Exercise to the Company. If the Company’s common stock is then traded in a Trading Market and the Class is a series of the Company’s convertible preferred stock, the fair market value of a Share shall be the closing price or last sale price of a share of the Company’s common stock reported for the business day immediately before the date on which Holder delivers this Warrant together with its Notice of Exercise to the Company multiplied by the number of shares of the Company’s common stock into which a Share is then convertible. If the Company’s common stock is not traded in a Trading Market, the Board of Directors of the Company shall determine the fair market value of a Share in its reasonable good faith judgment.

1.4 Delivery of Certificate and New Warrant. Promptly after Holder exercises or converts this Warrant in the manner set forth in Article 1.2 or 1.3 above, the Company shall deliver to Holder a certificate representing the Shares issued to Holder upon such exercise or conversion and, if this Warrant has not been fully exercised or converted and has not expired, a new warrant of like tenor representing the Shares not so acquired.

1.5 Replacement of Warrant. On receipt of evidence reasonably satisfactory to the Company of the loss, theft, destruction or mutilation of this Warrant and, in the case of loss, theft or destruction, on delivery of an indemnity agreement reasonably satisfactory in form, substance and amount to the Company or, in the case of mutilation, on surrender of this Warrant to the Company for cancellation, the Company shall promptly execute and deliver to Holder, in lieu of this Warrant, a new warrant of like tenor and amount.

1.6 Holder’s Obligation to Execute Investors’ Rights Agreement and Voting Agreement. As to any Shares Holder receives upon any exercise or conversion of this Warrant, Holder agrees to be bound by that certain Amended and Restated Investors’ Rights Agreement dated as of May 16, 2014 and that certain Amended and Restated Voting Agreement dated as of May 16, 2014, each by and among the Company and certain of the Company’s stockholders (as each may be amended from time to time), or similar agreements.

1.7.1 Acquisition. For the purpose of this Warrant, “Acquisition” means any: (i) sale, lease, exclusive license, or other disposition of all or substantially all of the assets of the Company. (ii) any merger or consolidation of the Company into or with another person or entity (other than a merger or consolidation effected exclusively to change the Company’s domicile), or any other corporate reorganization, in which the stockholders of the Company in their capacity as such immediately prior to such merger, consolidation or reorganization, own or beneficially own less than a majority of the Company’s (or the surviving or successor entity’s) outstanding voting power immediately after such merger, consolidation or reorganization; or (iii) any sale or other transfer by the stockholders of the Company of shares representing at least a majority of the Company’s then-total outstanding combined voting power. Notwithstanding the foregoing, Acquisition shall not include the sale of stock by the Company for capital raising purposes.

A) In the event of an Acquisition in which the consideration to be received by the Company’s stockholders consists solely of cash, solely of Marketable Securities or a combination of cash and Marketable Securities, either: (i) Holder shall exercise its conversion or purchase right under this Warrant and such exercise will be deemed effective immediately prior to and contingent upon the consummation of such Acquisition, or (ii) if Holder does not exercise the Warrant, this Warrant will expire immediately prior to the-consummation of such Acquisition. The Company shall provide Holder with written notice relating to the foregoing (together with such reasonable information as Holder may reasonably require regarding the treatment of this Warrant in connection with such contemplated Acquisition giving rise to such notice), which is to be delivered to Holder not less than ten (10) days prior to the closing of the proposed Acquisition. In the event the Company does not provide such notice, then if, upon the Acquisition, the fair market value of one Share (or other security issuable upon the exercise hereof) as determined in accordance with Section 1.3 above would be greater than the Warrant Price in effect on such date, then this Warrant shall automatically be deemed on and as of such date to be exercised and converted pursuant to Section 1.2 above as to all Shares (or such other securities) for which it shall not previously have been exercised or converted, and the Company shall promptly notify the Holder of the number of Shares (or such other securities) issued upon such automatic exercise and conversion to the Holder and Holder shall be deemed to have restated each of the representations and warranties in Article 4 of the Warrant as the date thereof.

B) Upon the closing of any Acquisition other than as particularly described in subsection (A) above, the acquiring, surviving or successor entity shall assume the obligations of this Warrant, and this Warrant shall thereafter be exercisable for the same securities and/or other property as would have been paid for the Shares issuable upon exercise of the unexercised portion of this Warrant as if such Shares were outstanding on and as of the record date for such Acquisition, subject to further adjustment from time to time in accordance with the provisions of this Warrant.

C) As used in this Article 1.7, “Marketable Securities” means securities meeting all of the following requirements: (i) the issuer thereof is then subject to the reporting requirements of Section 13 or Section 15(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and is then current in its filing of all required reports and other information under the Act and the Exchange Act; (ii) the class and series of shares or other security of the issuer that would be received by Holder in connection with the Acquisition were Holder to exercise or convert this Warrant on or prior to the closing thereof is then traded in Trading Market; and (iii) Holder would not be not be restricted by contract or by applicable federal and state securities laws from publicly re-selling, within six (6) months following the closing of such Acquisition, all of the issuer’s shares and/or other securities that would be received by Holder in such Acquisition were Holder to exercise or convert this Warrant in full on or prior to the closing of such Acquisition.

2.1 Stock Dividends, Splits, Etc. If the Company declares or pays a dividend on the outstanding shares of the Class payable in common stock or other securities or property (other than cash), then upon exercise or conversion of this Warrant, for each Share acquired, Holder shall receive, without additional cost to Holder, the total number and kind of securities and property which Holder would have received had Holder owned the Shares of record as of the date the dividend occurred. If the Company subdivides the outstanding shares of the Class by reclassification or otherwise into a greater number of shares, the number of Shares purchasable hereunder shall be proportionately increased and the Warrant Price shall be proportionately decreased. If the outstanding shares of the Class are combined or consolidated, by reclassification or otherwise, into a lesser number of shares, the Warrant Price shall be proportionately increased and the number of Shares shall be proportionately decreased.

2.2 Reclassification, Exchange, Combinations or Substitution. Upon any event whereby all of the outstanding shares of the Class are reclassified, exchanged, combined, substituted, or replaced for, into, with or by Company securities of a different class and/or series, then from and after the consummation of such event, this Warrant will be exercisable for the number, class and series of Company securities that Holder would have received had the Shares been outstanding on and as of the consummation of such event, and subject to further adjustment thereafter from time to time in accordance with the provisions of this Warrant. The provisions of this Article 2.2 shall similarly apply to successive reclassifications, exchanges, combinations substitutions, replacements or other similar events.

2.3 Conversion of Preferred Stock. If the Class is a class and series of the Company’s convertible preferred stock, in the event that all outstanding shares of the Class are converted, automatically or by action of the holders thereof, into common stock pursuant to the provisions of the Company’s Certificate of Incorporation, then from and after the date on which all outstanding shares of the Class have been so converted, this Warrant shall be exercisable for such number of shares of common stock into which the Shares would have been converted had the Shares been outstanding on the date of such conversion, and the Warrant Price shall equal the Warrant Price in effect as of immediately prior to such conversion divided by the number of shares of common stock into which one Share would have been converted, all subject to further adjustment thereafter from time to time in accordance with the provisions of this Warrant.

2.4 Adjustments for Diluting Issuances. Without duplication of any adjustment otherwise provided for in this Article 2, the number of shares of common stock issuable upon conversion of the Shares shall be subject to adjustment_; from time to time in the manner set forth in the Company’s Certificate of Incorporation (as amended from time to time) as if the Shares were issued and outstanding on and as of the date of any such required adjustment.

2.5 No Fractional Share. No fractional Share shall be issuable upon exercise or conversion of the Warrant and the number of Shares to be issued shall be rounded down to the nearest whole Share. If a fractional Share interest arises upon any exercise or conversion of the Warrant, the Company shall eliminate such fractional Share interest by paying Holder in cash the amount computed by multiplying the fractional interest by (i) the fair market value (as determined in accordance with Article 1.3 above) of a full Share, less (ii) the then-effective Warrant Price.

2.6 Certificate as to Adjustments. Upon each adjustment of the Warrant Price, Class and/or number of Shares, the Company shall promptly notify Holder in writing, and, at the Company’s expense, promptly compute such adjustment, and furnish Holder with a certificate of its Chief Financial Officer or other duly authorized officer setting forth such adjustment and the facts upon which such adjustment is based. The Company shall, upon written request, furnish Holder a certificate setting forth the Warrant Price, Class and number of Shares in effect upon the date thereof and the series of adjustments leading to such Warrant Price, Class and number of Shares.
