consideration, the receipt of which is hereby acknowledged, COMERICA BANK, a Texas banking association, or its assignee (“Holder”), is entitled to purchase the number of fully paid and nonassessable shares of the class of securities (the
“Shares”) of ROKA BIOSCIENCE, INC. (the “Company”) at the Warrant Price, all as set forth above and as adjusted pursuant to the terms of this Warrant, subject to the provisions and upon the terms and conditions set forth in this
Warrant. 
 ARTICLE 1 

EXERCISE 
 1.1 Method of
Exercise. Holder may exercise this Warrant by a duly executed Notice of Exercise in substantially the form attached as Appendix I to the principal office of the Company (or such other appropriate location as Holder is so instructed by the
Company). Holder shall also deliver to the Company a check, wire transfer (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 [Reserved]. 
 1.3
Delivery of Certificate and New Warrant. Within 30 days after Holder exercises this Warrant and the Company receives payment of the aggregate Warrant Price, the Company shall deliver to Holder certificates for the Shares acquired and, if this
Warrant has not been fully exercised and has not expired, a new warrant representing the Shares not so acquired. 
 1.4 Replacement of
Warrants. In the case of loss, theft or destruction of this Warrant, upon delivery of an indemnity agreement reasonably satisfactory in form and amount to the Company or, in the case of mutilation, upon surrender and cancellation of this
Warrant, the Company at its expense shall execute and deliver, in lieu of this Warrant, a new warrant of like tenor. 







 1.5 Acquisition of the Company. 

1.5.1 “Acquisition.” For the purpose of this Warrant, “Acquisition” means (a) any sale,
license, or other disposition of all or substantially all of the assets (including intellectual property) of the Company, or (b) any reorganization, consolidation, merger, sale of the voting securities of the Company or other transaction or
series of related transactions where the holders of the Company’s securities before the transaction or series of related transactions beneficially own less than 50% of the outstanding voting securities of the surviving entity after the
transaction or series of related transactions. 
 1.5.2 Treatment of Warrant in the Event of an Acquisition. The
Company shall give Holder written notice at least 15 days prior to the closing of any proposed Acquisition. The Company will use commercially reasonable efforts to cause (i) the acquirer of the Company, (ii) successor or surviving entity
or (iii) parent entity in an Acquisition (the “Acquirer”) to assume this Warrant as a part of the Acquisition. 

(a) If the Acquirer assumes this Warrant, then this Warrant shall be exercisable for the same securities, cash, and property as
would be payable for the Shares issuable upon exercise of the unexercised portion of this Warrant as if such Shares were outstanding on the record date for the Acquisition and subsequent closing. The Warrant Price shall be adjusted accordingly, and
the Warrant Price and number and class of Shares shall continue to be subject to adjustment from time to time in accordance with the provisions hereof. 

(b) If the Acquirer refuses to assume (i) this Warrant (ii) all other warrants of the Company and (iii) employee
or other options of the Company, then in connection with the Acquisition, the Company shall give Holder an additional written notice at least ten (10) days prior to the closing of the Acquisition of such fact. In such event, notwithstanding any
other provision of this Warrant to the contrary, Holder may immediately exercise this Warrant in the manner specified in this Warrant with such exercise effective immediately prior to closing of the Acquisition. If Holder elects not to exercise this
Warrant, then this Warrant will terminate immediately prior to the closing of the Acquisition. Notwithstanding any other provision of this Warrant to the contrary if the Acquirer refuses to assume this Warrant in connection with such Acquisition,
other than in connection with an Excluded Acquisition (as defined below), then effective as of the date that is ten (10) days prior to the closing of such Acquisition, the Holder shall have the option to elect that the Warrant Price be
adjusted, without further action of any party, to be fifty percent (50%) of the fair market value of the Warrant Shares (or such lesser amount as is actually received in value per share of the Acquirer in exchange for the Warrant Shares). As
used herein, an “Excluded Acquisition” means, an Acquisition where the consideration that the holders of the Shares are entitled to receive on account of the Shares consists entirely of cash and/or shares of common stock that are publicly
traded on a national exchange and where the shares, if any, receivable by the Holder of this Warrant were the Holder to exercise this Warrant in full immediately prior to the closing of such Acquisition may be publicly


  
 -2- 








 
re-sold by the Holder in their entirety within the three (3) months following such closing pursuant to Rule 144 or an effective registration statement under the Act. In the event the
Acquirer has assumed any other warrants of the Company or employee or other options of the Company, then Acquirer shall assume this Warrant. 

ARTICLE 2 
 ADJUSTMENTS
TO THE SHARES 
 2.1 Stock Dividends, Splits, Etc. If the Company declares or pays a dividend on its common stock payable in
common stock, or other securities, or subdivides the outstanding common stock into a greater amount of common stock, then upon exercise of this Warrant, for each Share acquired, Holder shall receive, without cost to Holder, the total number and kind
of securities to which Holder would have been entitled had Holder owned the Shares of record as of the date the dividend or subdivision occurred. 

2.2 Reclassification, Exchange or Substitution. Upon any reclassification, exchange, substitution, or other event that results in a
change of the number and/or class of the securities issuable upon exercise or conversion of this Warrant, Holder shall be entitled to receive, upon exercise or conversion of this Warrant, the number and kind of securities and property that Holder
would have received for the Shares if this Warrant had been exercised immediately before such reclassification, exchange, substitution, or other event. Such an event shall include any automatic conversion of the outstanding or issuable securities of
the Company of the same class or series as the Shares to common stock pursuant to the terms of the Company’s Certificate of Incorporation upon the closing of a registered public offering of the Company’s common stock. The Company or its
successor shall promptly issue to Holder a new warrant for such new securities or other property. The new warrant shall provide for adjustments which shall be as nearly equivalent as may be practicable to the adjustments provided for in this
Article 2 including, without limitation, adjustments to the Warrant Price, the number of securities or property issuable upon exercise of the new warrant and expiration date. The provisions of this Section 2.2 shall similarly apply to
successive reclassifications, exchanges, substitutions, or other events. 
 2.3 Adjustments for Combinations, Etc. If the outstanding
Shares are combined or consolidated, by reclassification, reverse split or otherwise, into a lesser Number of Shares, the Warrant Price shall be proportionately increased. If the outstanding Shares are split or multiplied, by reclassification or
otherwise, into a greater Number of Shares, the Warrant Price shall be proportionately decreased. 
 2.4 Adjustments for Diluting
Issuances. Without duplication of any adjustment made pursuant to Section 1.6, in the event of the issuance (a “Diluting Issuance”) by the Company, after the Issue Date of this Warrant, of securities at a price per share less than
the Warrant Price, then the number of shares of common stock issuable upon conversion of the Shares shall be adjusted in accordance with those provisions of the Company’s Certificate of Incorporation, a copy of which is attached hereto as
Exhibit B, which apply to Diluting Issuances as if the Shares were outstanding on the date of such Diluting Issuance. The provisions set forth for the Shares in the Company’s Certificate of Incorporation relating to the above in
effect as of the Issue Date may not be amended, modified or 

  
 -3- 








 
waived, without the prior written consent of Holder unless such amendment, modification or waiver affects the rights associated with the Shares in the same manner as such amendment, modification
or waiver affects the rights associated with all other shares of the same series and class as the Shares granted to the Holder. Under no circumstances shall the aggregate Warrant Price payable by the Holder upon exercise of this Warrant increase as
a result of any adjustment arising from a Diluting Issuance. 
 2.5 No Impairment. The Company shall not, by amendment of its
Certificate of Incorporation or through a 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 under this Warrant by the Company, but shall at all times in good faith assist in carrying out all the provisions of this Article 2 and in taking all such action as may be necessary or appropriate to protect
Holder’s rights under this Article 2 against impairment. 
 2.6 Certificate as to Adjustments. Upon each adjustment of the
Warrant Price, the Company at its expense shall promptly compute such adjustment, and furnish Holder with a certificate signed by its Chief Financial 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 in effect upon the date thereof and the series of adjustments leading to such Warrant Price. 

2.7 Fractional Shares. No fractional Shares shall be issuable upon exercise of this 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 of this Warrant, the Company shall eliminate such fractional share interest by paying Holder an amount in cash computed by multiplying the fractional
interest by the fair market value, as determined by the Company’s Board of Directors, of a full Share.

 3.1 Representations and Warranties. The Company hereby represents and warrants to, and agrees
with, the Holder as follows:

than the price per share at which the Shares were most recently issued as of the date of this Warrant. 
 3.1.2 All Shares
which may be issued upon the exercise of the purchase right represented by this Warrant, and all securities, if any, issuable upon conversion of the Shares, shall, upon issuance, be duly authorized, validly issued, fully paid and nonassessable, and
free of any liens and encumbrances except for restrictions on transfer provided for herein or under applicable federal and state securities laws.

shares of stock of any class or series or other rights; (c) to effect any reclassification or recapitalization of stock; or (d) to merge or consolidate with or into any other corporation, or sell, lease, license, or convey all or
substantially all of its assets, or to liquidate, dissolve or wind up, then, in connection with each such event, the Company shall give Holder (1) at least 20 days prior written notice of the date on which a record will be taken for such

(2) in the case of the matters referred to in (c) and (d) above at least 20 days prior written notice of the date when the same will take place (and specifying the date on which the holders of stock will be entitled to exchange their
stock for securities or other property deliverable upon the occurrence of such event). Upon request, the Company shall provide Holder with such information reasonably necessary for Holder to evaluate its rights as a holder of this Warrant or Warrant
Shares in the case of matters referred to (a), (b), (c) and (d) herein above. 
 3.3 Information Rights. 

3.3.1 So long as the Holder holds this Warrant and/or any of the Shares, the Company shall deliver to the Holder

audited financial statements of the Company certified by independent public accountants of recognized standing and (c) within forty-five (45) days after the end of each of the first three quarters of each fiscal year, the Company’s
quarterly, unaudited financial statements. In addition, and without limiting the generality of the foregoing, so long as the Holder holds this Warrant and/or any of the Shares, the Company shall afford to the Holder the same access to information
concerning the Company and its business and financial condition as would be afforded to a holder of the class of Shares under applicable state law and/or any agreement with any holder of the class of Shares. Non-compliance with the foregoing shall
not constitute a breach of this Warrant provided that the Company complies within a ten (10) business day cure period. 

3.3.2 The Company shall deliver to Holder, in the event that the Company becomes subject to the reporting requirements under
the Securities Exchange Act (“SEC”) of 1934, within five (5) days of filing, copies of all periodic and other reports, proxy statements and other materials filed by the Company with the SEC or similarly acting governmental agency, any
national securities exchange, or distributed to its shareholders, as the case may be. Documents required to be delivered pursuant to the terms hereof (to the extent any such documents are included in materials otherwise filed with the SEC) may be
delivered electronically and if so delivered, shall be deemed to have been delivered on the date on which the Company posts such documents, or provides a link thereto, on the Company’s website on the Internet at the Company’s website
address; provided, however, the Company shall promptly notify Holder in writing (which may be by electronic mail) of the posting of any such documents. As to any information contained in the materials furnished pursuant to this Section 3.1.2,
the Company 

  
 -5- 








 
shall not be required separately to furnish such information under Sections 3.1.1(b)-(c), but the foregoing shall not be in derogation of the
obligation of the Company to furnish the information and materials described in such Sections 3.1.1(b)-(c) at the times specified therein. 

3.4 Registration Under the Act. The Company agrees that the Shares or, if the Shares are convertible into common stock of the Company,

the Company and its investors dated as of November 20, 2013 (the “Agreement”), a copy of which is attached hereto as Exhibit C. The Company agrees that no amendments will be made to the Agreement which would have an
adverse impact on Holder’s registration rights hereunder this provision. Holder shall be deemed to be a party to the Agreement solely for the purpose of the above-mentioned registration rights.
