Exhibit 10.7


 


Warrant No. 2014-[___]


 


CDx, Inc.


(a Delaware Corporation)


 


Warrant for the Purchase of [________]
Shares of Series B Preferred Stock


 


This Warrant Will Be Void After 5:00
P.M. Pacific Time On [________ ___], 2019


 


These securities have not been registered
with the U.S. Securities and Exchange Commission (the “SEC”) under the Securities Act of 1933, as amended (the
“Securities Act”), and are being offered in reliance on exemptions from registration provided in Section 4(2)
of the Securities Act and Rule 506 of Regulation D promulgated thereunder and preemption from the registration or qualification
requirements (other than notice filing and fee provisions) of applicable state laws under the National Securities Markets Improvement
Act of 1996.


 


THIS WARRANT (this
“Warrant”), effective as of [________ ___], 2014 (the “Effective Date”), certifies
that, for value received, [________] or registered assigns (the “Holder” or “Holders”),
is entitled, at any time on or before 5:00 p.m. Pacific Time on [five year anniversary of Initial Closing], 2019, to subscribe
for, purchase, and receive [________] ([________]) shares (the “Shares”) of fully paid and non-assessable
Series B Preferred Stock, par value $0.001 per share (the “Series B Preferred Stock”) of CDx, Inc., a
Delaware corporation (the “Company”). This Warrant is exercisable at a price of One Dollar Ten Cents
($1.10) per share for an aggregate exercise price of [________] $[________] (the “Exercise Price”). The
number of Shares to be received upon exercise of this Warrant and the Exercise Price may be adjusted on the occurrence of certain
events as described herein. If the rights represented hereby are not exercised by 5:00 p.m. Pacific Time on [five year anniversary
of Initial Closing], 2019, this Warrant shall automatically become void and of no further force or effect, and all rights represented
hereby shall cease and expire.


 


Subject to the terms
set forth herein, this Warrant may be assigned by the Holder in whole or in part by execution of the form of assignment attached
hereto or may be exercised by the Holder in whole or in part by execution of the form of exercise attached hereto and payment of
the Exercise Price in the manner described herein, all subject to the terms hereof.


 


1.          Exercise
of Warrants. The Holder shall have the rights of a stockholder only with respect to Shares fully paid for by the Holder under
this Warrant. Upon the exercise of all or any portion of this Warrant in the manner provided herein, the Holder exercising the
same shall be deemed to have become a Holder of record of the Shares as to which this Warrant is exercised for all purposes, and
certificates for the securities so purchased shall be delivered to the Holder within a reasonable time. If this Warrant shall be
exercised in respect to only a part of the Shares covered hereby, the Holder shall be entitled to receive a similar Warrant of
like tenor and date covering the number of Shares with respect to which this Warrant shall not have been exercised.


 


2.          Assignment
of Warrants. In the event this Warrant is assigned in the manner provided herein, the Company, upon request and upon surrender
of this Warrant by the Holder at the principal office of the Company accompanied by payment of all transfer taxes, if any, payable
in connection therewith, shall transfer this Warrant on the books of the Company. If the assignment is in whole, the Company shall
execute and deliver a new Warrant or Warrants of like tenor to this Warrant to the appropriate assignee expressly evidencing the
right to purchase the aggregate number of Shares purchasable hereunder; and if the assignment is in part, the Company shall execute
and deliver to the appropriate assignee a new Warrant or Warrants of like tenor expressly evidencing the right to purchase the
portion of the aggregate number of Shares as shall be contemplated by any such agreement, and shall concurrently execute and deliver
to the Holder a new Warrant of like tenor to this Warrant evidencing the right to purchase the remaining portion of the Shares
purchasable hereunder that have not been transferred to the assignee.


 




    	 



    	 



    

 


3.           Fully
Paid Shares. The Company covenants and agrees that the Shares that may be issued on the exercise of this Warrant will, on issuance
pursuant to the terms of this Warrant, be fully paid and non-assessable, free from all taxes, liens, and charges with respect to
the issue thereof, and not issued in violation of the preemptive or similar right of any other person. The Company further covenants
and agrees that during the period within which the rights represented by this Warrant may be exercised, the Company will have authorized
and reserved a sufficient number of Shares of Series B Preferred Stock to provide for the exercise of the rights represented by
this Warrant.


 


4.           Adjustments.


 


(a)          Merger
or Reorganization. If at any time there shall be any reorganization, recapitalization, merger or consolidation (a “Reorganization”)
involving the Company in which shares of the Company’s stock are converted into or exchanged for securities, cash or other
property, then, as a part of such Reorganization, lawful provision shall be made so that the Holder shall thereafter be entitled
to receive upon exercise of this Warrant, the kind and amount of securities, cash or other property of the successor corporation
resulting from such Reorganization, equivalent in value to that which a holder of the Shares deliverable upon exercise of this
Warrant would have been entitled in such Reorganization if the right to purchase the Shares hereunder had been exercised immediately
prior to such Reorganization. In any such case, appropriate adjustment (as determined in good faith by the Board of Directors of
the successor corporation) shall be made in the application of the provisions of this Warrant with respect to the rights and interests
of the Holder after such Reorganization to the end that the provisions of this Warrant shall be applicable after the event, as
near as reasonably may be, in relation to any shares or other securities deliverable after that event upon the exercise of this
Warrant.


 


(b)          Reclassification
of Shares. If the securities issuable upon exercise of this Warrant are changed into the same or a different number of securities
of any other class or classes by reclassification, capital reorganization, conversion of all outstanding shares of the relevant
class or series or otherwise (other than as otherwise provided for herein) (a “Reclassification”), then,
in any such event, in lieu of the number of Shares which the Holder would otherwise have been entitled to receive, the Holder shall
have the right thereafter to exercise this Warrant for a number of shares of such other class or classes of stock that a holder
of the number of securities deliverable upon exercise of this Warrant immediately before that change would have been entitled to
receive in such Reclassification, all subject to further adjustment as provided herein with respect to such other shares.


 


(c)          Subdivisions
and Combinations. In the event that the outstanding shares of Series B Preferred Stock are subdivided (by stock split, by payment
of a stock dividend or otherwise) into a greater number of shares of such securities, the number of Shares issuable upon exercise
of the rights under this Warrant immediately prior to such subdivision shall, concurrently with the effectiveness of such subdivision,
be proportionately increased, and the Exercise Price shall be proportionately decreased, and in the event that the outstanding
shares of Series B Preferred Stock are combined (by reclassification or otherwise) into a lesser number of shares of such securities,
the number of Shares issuable upon exercise of the rights under this Warrant immediately prior to such combination shall, concurrently
with the effectiveness of such combination, be proportionately decreased, and the Exercise Price shall be proportionately increased.


 


(d)          Notice
of Adjustments. Upon any adjustment in accordance with this Paragraph 4, the Company shall give notice thereof to the Holder,
which notice shall state the event giving rise to the adjustment, the Exercise Price as adjusted and the number of securities or
other property purchasable upon the exercise of the rights under this Warrant, setting forth in reasonable detail the method of
calculation of each. The Company shall, upon the written request of any Holder, furnish or cause to be furnished to such Holder
a certificate setting forth (i) such adjustments, (ii) the Exercise Price at the time in effect and (iii) the number of securities
and the amount, if any, of other property that at the time would be received upon exercise of this Warrant.


 




    	 



    	 



    

 


5.                          Notice
of Certain Events. In the event of:


 


(a)          any
taking by the Company of a record of the holders of any class of securities of the Company for the purpose of determining the holders
thereof who are entitled to receive any dividends or other distribution, or any right to subscribe for, purchase, or otherwise
acquire any shares of stock of any class or any other securities or property, or to receive any other rights;


 


(b)          any
capital reorganization of the Company, any reclassification or recapitalization of the capital stock of the Company, or any transfer
of all or substantially all of the assets of the Company to any other person, or any consolidation, share exchange, or merger involving
the Company; or


 


(c)          any
voluntary or involuntary dissolution, liquidation, or winding up of the Company,


 


the Company will mail to the Holder(s)
of this Warrant, at least 20 days prior to the earliest date specified therein, a notice specifying the date on which any such
record is to be taken for the purpose of such dividend, distribution, or right; the amount and character of such dividend, distribution,
or right; or the date on which any such reorganization, reclassification, transfer, consolidation, share exchange, merger, dissolution,
liquidation, or winding up of the Company will occur and the terms and conditions of such transaction or event.


 


6.           Limitation
of Transfer. Subject to the restrictions set forth in Paragraph 8 hereof, this Warrant is transferable at the offices of the
Company. On such transfer, each Holder hereof agrees that the Company may deem and treat the registered Holder(s) of this Warrant
as the true and lawful owner(s) thereof for all purposes, and the Company shall not be affected by any notice to the contrary.


 


7.           Disposition
of Warrants or Shares. Holder, by acceptance hereof, agrees for itself and any subsequent owner(s) that, before any disposition
is made of any Warrants or shares of Series B Preferred Stock, Holder shall give written notice to the Company describing briefly
the manner of any such proposed disposition. No such disposition shall be made unless and until:


 


(a)          the
Company has received written assurances from the proposed transferee confirming a factual basis for relying on exemptions from
registration under applicable federal and state securities laws for such transfer or an opinion from counsel for the Holder(s)
of the Warrants or Shares stating that no registration under the Securities Act or applicable state statute is required with respect
to such disposition; or


 


(b)          a
registration statement under the Securities Act has been filed by the Company and declared effective by the SEC covering such proposed
disposition and the disposition has been registered or qualified, or is exempt therefrom, under the state having jurisdiction over
such disposition.


 




    	 



    	 



    

 


8.           Restricted
Securities: Registration of Securities.


 


(a)          Restricted
Securities; Rule 144. As of the original date of issuance of this Warrant, there is no public market for the Company’s
Series B Preferred Stock, and there is no assurance that a public market will ever be created, or if created, that it will be an
active, sustainable trading market. Moreover, the Holder acknowledges that this Warrant is, and that the Shares issuable on exercise
hereof will be, “restricted securities” as that term is defined in Rule 144 promulgated under the Securities Act. Rule
144 requires that securities issued by a non-reporting company in a transaction not involving a public offering must be held for
a minimum of one year from the date of full payment for the securities purchased before such securities become eligible to be publicly
sold under Rule 144, even if all other conditions required for resale under Rule 144 have been met. There is no assurance that
the conditions to satisfy Rule 144 will ever be satisfied. Accordingly, this Warrant must be taken for investment and held indefinitely.
Likewise, any Shares issued upon exercise of this Warrant must be taken for investment and held indefinitely and may not be resold
unless such resale is registered under the Securities Act and/or comparable state securities laws or unless an exemption from such
registration is available. A legend to the foregoing effect shall be placed conspicuously on the face of all certificates for Shares
issuable on exercise of this Warrant.


 


(b)          Registration
of Securities. The Company has agreed to file a resale registration statement with the SEC covering the resale of the Shares
issuable upon exercise of this Warrant. However, there is no assurance that such registration process will be completed by such
time as the Holder desires to sell the Shares, if ever. Even if Rule 144 or an effective registration statement is available, the
Holder may find it difficult to resell the Shares in the public market, and therefore, investors may have to hold their Shares
indefinitely.


 


9.           Governing
Law. This Warrant shall be construed under and be governed by the laws of the state of California.


 


10.         Notices.
 Any notice, request or other document required or permitted to be given or delivered to the Holder by the Company shall be
delivered in accordance with the notice provisions of the Purchase Agreement.


 


11.         Non-waiver
and Expenses. No course of dealing or any delay or failure to exercise any right hereunder on the part of Holder shall operate
as a waiver of such right or otherwise prejudice Holder’s rights, powers or remedies, notwithstanding the fact that all rights
hereunder terminate on the Expiration Date. If the Company willfully and knowingly fails to comply with any provision of this Warrant,
which results in any material damages to the Holder, the Company shall pay to Holder such amounts as shall be sufficient to cover
any costs and expenses including, but not limited to, reasonable attorneys’ fees, including those of appellate proceedings,
incurred by Holder in collecting any amounts due pursuant hereto or in otherwise enforcing any of its rights, powers or remedies
hereunder.


 


12.         Remedies.
Holder, in addition to being entitled to exercise all rights granted by law, including recovery of damages, will be entitled to
specific performance of its rights under this Warrant. The Company agrees that monetary damages would not be adequate compensation
for any loss incurred by reason of a breach by it of the provisions of this Warrant and hereby agrees to waive the defense in any
action for specific performance that a remedy at law would be adequate.


 


13.         Successors
and Assigns. Subject to applicable securities laws, this Warrant and the rights and obligations evidenced hereby shall inure
to the benefit of and be binding upon the successors of the Company and the successors and permitted assigns of Holder. The provisions
of this Warrant are intended to be for the benefit of all Holders of this Warrant from the Initial Exercise Date through the Termination
Date, and shall be enforceable by any such Holder or holder of Warrant Shares.


 


14.         Amendment.
This Warrant may be modified or amended or the provisions hereof waived with the written consent of the Company and a majority
in interest of the Holders acquiring warrants pursuant to that certain Series B Preferred Stock and Warrant Purchase Agreement
dated October [___], 2014 between the Company and the investors listed on Schedule I thereto.


 


15.         Severability.
Wherever possible, each provision of this Warrant shall be interpreted in such manner as to be effective and valid under applicable
law, but if any provision of this Warrant shall be prohibited by or invalid under applicable law, such provision shall be ineffective
to the extent of such prohibition or invalidity, without invalidating the remainder of such provisions or the remaining provisions
of this Warrant.


 




    	 



    	 



    

 


16.         Headings.
The headings used in this Warrant are for the convenience of reference only and shall not, for any purpose, be deemed a part of
this Warrant.


 


17.         Loss,
Theft, Destruction, or Mutilation. Upon receipt by the Company of reasonable evidence of the ownership of and the loss, theft,
destruction, or mutilation of this Warrant, the Company will execute and deliver, in lieu thereof, a new Warrant of like tenor.


 


18.         Taxes.
The Company will pay all taxes in respect of the issue of this Warrant or the Shares issuable upon exercise thereof.


 




    	 



    	 



    

 


IN WITNESS WHEREOF,
the Company has caused this Warrant to be executed by its officers thereunto duly authorized as of the date first written above.
