	  	 Warrant to Purchase

Shares of Common Stock


 THIS CERTIFIES THAT, for value received, ____________________________, or its registered
assigns (the “Holder”), is entitled, subject to the provisions and upon the terms and conditions set forth herein, to purchase from DermTech International, a California corporation (the “Company”)
shares of the Company’s Common Stock (the “Shares”) in the amounts, at such times and at the price per share set forth in Section 1. The term “Warrant” as used herein shall include this
Warrant and any warrants delivered in substitution or exchange therefor as provided herein. This Warrant is issued in connection with the transactions described in the _______________Agreement, dated as of [_______________], by and between the
Company and the Holder. 
 The following is a statement of the rights of the Holder and the conditions to which this Warrant
is subject, and to which Holder, by acceptance of this Warrant, agrees: 

1.        Number and Price of Shares; Exercise Period. 

(a)        Number of Shares. Subject to any previous exercise of the
Warrant, the Holder shall have the right to purchase up to [_______] Shares, as may be adjusted pursuant hereto, prior to (or in connection with) the expiration of this Warrant as provided in Section 9. 

(b)        Exercise Price. The exercise price per Share shall be equal
to $[______], subject to adjustment pursuant hereto (the “Exercise Price”). 

(c)        Exercise Period. This Warrant shall be exercisable, in whole
or in part, prior to (or in connection with) the expiration of this Warrant as set forth in Section 9. 

2.        Vesting of the Warrant 

(a)        [_____________________] 

 












 (b)        The entire warrant shall
immediately and fully vest one week prior to a change of control. The company shall notify the warrant holder of a pending change of control. 

3.        Exercise of the Warrant. 

(a)        Exercise. The purchase rights represented by this Warrant
may be exercised at the election of the Holder, in whole or in part, in accordance with Section 1, by: 

(i)      the tender to the Company at its principal office (or such other office or agency as
the Company may designate) of a notice of exercise in the form of Exhibit A (the “Notice of Exercise”), duly completed and executed by or on behalf of the Holder, together with the surrender of this Warrant; and 

(ii)     the payment to the Company of an amount equal to (x) the Exercise Price multiplied by
(y) the number of Shares being purchased, by (a) wire transfer or certified, cashier’s or other check acceptable to the Company and payable to the order of the Company; (b) surrender and cancellation of promissory notes or other
instruments representing indebtedness of the Company to the Holder; or (c) a combination of (a) and (b). 

(b)        Net Issue Exercise. In lieu of exercising this Warrant
pursuant to Section 2(a)(ii), if the fair market value of one Share is greater than the Exercise Price (at the date of calculation as set forth below), the Holder may elect to receive a number of Shares equal to the value of this Warrant (or of
any portion of this Warrant being canceled) by surrender of this Warrant at the principal office of the Company (or such other office or agency as the Company may designate) together with a properly completed and executed Notice of Exercise
reflecting such election, in which event the Company shall issue to the Holder that number of Shares computed using the following formula: 
  

									
		 		 	  X      	  	=    	  	         Y (A –
B)        

		  		  	 A

					
	 Where:
	 		 		  		  	
			
	 X       
	 	=    	 	The number of Shares to be issued to the Holder
			
	 Y       
	 	=    	 	The number of Shares purchasable under this Warrant or, if only a portion of the Warrant is being exercised, the portion of the Warrant being canceled (at the date of such calculation)
			
	 A       
	 	=    	 	The fair market value of one Share (at the date of such calculation)
			
	 B       
	 	=    	 	The Exercise Price (as adjusted to the date of such calculation)


 For purposes of the calculation above, the fair market value of one Share shall be
determined by the Board of Directors of the Company, acting in good faith; provided, however, that: 

(i)        where a public market exists for the Company’s common stock at the
time of such exercise, the fair market value per Share shall be the average of the closing bid prices of the common stock or the closing price quoted on the national securities exchange on which the common stock is listed as published in the Wall
Street Journal, as applicable, for the ten (10) trading day period ending five (5) trading days prior to the date of determination of fair market value; and 

(ii)        if the Warrant is exercised in connection with the Company’s initial
public offering of common stock, the fair market value per Share shall be the per share offering price to the public of the Company’s initial public offering. 

  
 2 













 (c)        Stock
Certificates. The rights under this Warrant shall be deemed to have been exercised and the Shares issuable upon such exercise shall be deemed to have been issued immediately prior to the close of business on the date this Warrant is
exercised in accordance with its terms, and the person entitled to receive the Shares issuable upon such exercise shall be treated for all purposes as the holder of record of such Shares as of the close of business on such date. As promptly as
reasonably practicable on or after such date, and in any event within fifteen (15) days thereafter, the Company shall issue and deliver to the person or persons entitled to receive the same a certificate or certificates for that number of
shares issuable upon such exercise. In the event that the rights under this Warrant are exercised in part and have not expired, the Company shall execute and deliver a new Warrant reflecting the number of Shares that remain subject to this Warrant.

 (d)        No Fractional Shares or Scrip. No fractional shares or
scrip representing fractional shares shall be issued upon the exercise of the rights under this Warrant. In lieu of such fractional share to which the Holder would otherwise be entitled, the Company shall make a cash payment equal to the Exercise
Price multiplied by such fraction. 
 (e)        Conditional
Exercise. The Holder may exercise this Warrant conditioned upon (and effective immediately prior to) consummation of any transaction that would cause the expiration of this Warrant pursuant to Section 9 by so indicating in the notice of
exercise. 
 (f)        Automatic Exercise. If the Holder of this
Warrant has not elected to exercise this Warrant prior to expiration of this Warrant pursuant to Section 9, then this Warrant shall automatically (without any act on the part of the Holder) be exercised pursuant to Section 2(b) effective
immediately prior to the expiration of the Warrant to the extent such net issue exercise would result in the issuance of Shares, unless Holder shall earlier provide written notice to the Company that the Holder desires that this Warrant expire
unexercised. If this Warrant is automatically exercised, the Company shall notify the Holder of the automatic exercise as soon as reasonably practicable, and the Holder shall surrender the Warrant to the Company in accordance with the terms hereof.

 (g)        Reservation of Stock. The Company agrees during the
term the rights under this Warrant are exercisable to take all reasonable action to reserve and keep available from its authorized and unissued shares of Common Stock for the purpose of effecting the exercise of this Warrant such number of shares
(and shares of common stock for issuance on conversion of such shares) as shall from time to time be sufficient to effect the exercise of the rights under this Warrant; and if at any time the number of authorized but unissued shares of Common Stock
(and shares of common stock for issuance on conversion of such shares) shall not be sufficient for purposes of the exercise of this Warrant in accordance with its terms and the conversion of the Shares, without limitation of such other remedies as
may be available to the Holder, the Company will use all reasonable efforts to take such corporate action as may, in the opinion of counsel, be necessary to increase its authorized and unissued shares of its Common Stock (and shares of common stock
for issuance on conversion of such shares) to a number of shares as shall be sufficient for such purposes. 

4.        Replacement of the Warrant. Subject to the 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 and substance to the Company
or, in the case of mutilation, on surrender and cancellation of this Warrant, the Company at the expense of the Holder shall execute and deliver, in lieu of this Warrant, a new warrant of like tenor and amount. 

5.        Transfer of the Warrant. 

(a)        Warrant Register. The Company shall maintain a register (the
“Warrant Register”) containing the name and address of the Holder or Holders. Until this Warrant is transferred on the Warrant Register in accordance herewith, the Company may treat the Holder as shown on the Warrant Register
as the absolute owner of this Warrant for all purposes, notwithstanding any notice to the contrary. Any Holder of this Warrant (or of any portion of this Warrant) may change its address as shown on the Warrant Register by written notice to the
Company requesting a change. 

  
 3 













 (b)        Warrant
Agent. The Company may appoint an agent for the purpose of maintaining the Warrant Register referred to in Section 5(a), issuing the Shares or other securities then issuable upon the exercise of the rights under this Warrant, exchanging
this Warrant, replacing this Warrant or conducting related activities. 

(c)        Transferability of the Warrant. Subject to the provisions of
this Warrant with respect to compliance with the Securities Act of 1933, as amended (the “Securities Act”) and limitations on assignments and transfers, including without limitation compliance with the restrictions on
transfer set forth in Section 6, title to this Warrant may be transferred by endorsement (by the transferor and the transferee executing the assignment form attached as Exhibit B (the “Assignment Form”)) and
delivery in the same manner as a negotiable instrument transferable by endorsement and delivery. 

(d)        Exchange of the Warrant upon a Transfer. On surrender of
this Warrant (and a properly endorsed Assignment Form) for exchange, subject to the provisions of this Warrant with respect to compliance with the Securities Act and limitations on assignments and transfers, the Company shall issue to or on the
order of the Holder a new warrant or warrants of like tenor, in the name of the Holder or as the Holder (on payment by the Holder of any applicable transfer taxes) may direct, for the number of shares issuable upon exercise hereof, and the Company
shall register any such transfer upon the Warrant Register. This Warrant (and the securities issuable upon exercise of the rights under this Warrant) must be surrendered to the Company or its warrant or transfer agent, as applicable, as a condition
precedent to the sale, pledge, hypothecation or other transfer of any interest in any of the securities represented hereby. 

(e)        Taxes. In no event shall the Company be required to pay any
tax which may be payable in respect of any transfer involved in the issue and delivery of any certificate in a name other than that of the Holder, and the Company shall not be required to issue or deliver any such certificate unless and until the
person or persons requesting the issue thereof shall have paid to the Company the amount of such tax or shall have established to the satisfaction of the Company that such tax has been paid or is not payable. 

6.        Restrictions on Transfer of the Warrant and Shares; Compliance
with Securities Laws. By acceptance of this Warrant, the Holder agrees to comply with the following: 

(a)        Restrictions on Transfers. Subject to Section 6(b),
this Warrant may not be transferred or assigned in whole or in part without the Company’s prior written consent (which shall not be unreasonably withheld), and any attempt by Holder to transfer or assign any rights, duties or obligations that
arise under this Warrant without such permission shall be void. Any transfer of this Warrant, the Shares or the common stock issuable upon the conversion of the Shares (the “Securities”) must be in compliance with all
applicable federal and state securities laws. The Holder agrees not to make any sale, assignment, transfer, pledge or other disposition of all or any portion of the Securities, or any beneficial interest therein, unless and until the transferee
thereof has agreed in writing for the benefit of the Company to take and hold such Securities subject to, and to be bound by, the terms and conditions set forth in this Warrant, to the same extent as if the transferee were the original Holder
hereunder, and 
 (i)        there is then in effect a registration statement under
the Securities Act covering such proposed disposition and such disposition is made in accordance with such registration statement, or 

(ii)        (A) such Holder shall have given prior written notice to the Company
of such Holder’s intention to make such disposition and shall have furnished the Company with a detailed description of the manner and circumstances of the proposed disposition, (B) the transferee shall have confirmed to the satisfaction
of the Company in writing, substantially in the form of Exhibit A-1, that the Securities are being acquired (i) solely for the transferee’s own account and not as a nominee for any other party,
(ii) for investment and (iii) not with a view toward distribution or resale, and shall have confirmed such other matters related thereto as may be reasonably requested by the Company, and (C) if requested by the Company, such Holder
shall have furnished the Company, at the Holder’s expense and option, either (i) evidence reasonably satisfactory to the Company that such disposition will not require registration of such Securities under the Securities Act or (ii) a
“no action” letter from the Securities and Exchange Commission to the effect that the transfer of such Securities without registration will not result in a recommendation by the staff of the Securities and Exchange Commission that action
be taken with respect thereto, whereupon such Holder shall be entitled to transfer such Securities in accordance with the terms of the notice delivered by the Holder to the 

  
 4 













 
Company. It is agreed that the Company will not require opinions of counsel for transactions made pursuant to Rule 144 except in unusual circumstances. 

(b)        Permitted Transfers. Permitted transfers include (i) a
transfer not involving a change in beneficial ownership, or (ii) transactions involving the distribution without consideration of Securities by any Holder to (w) such Holder’s child, step-child, grandchild, parent, step-parent,
grandparent, spouse, sibling, mother-in-law, father-in-law, son-in-law, daughter-in-law,
sister-in-law or brother-in-law, or a trust for the benefit of any such family member,
(x) a parent, subsidiary or other affiliate of a Holder that is a corporation, limited liability company or limited partnership. 

(c)        Investment Representation Statement. Unless the rights under
this Warrant are exercised pursuant to an effective registration statement under the Securities Act that includes the Shares with respect to which the Warrant was exercised, it shall be a condition to any exercise of the rights under this Warrant
that the Holder shall have confirmed to the satisfaction of the Company in writing, substantially in the form of Exhibit A-1, that the Shares so purchased are being acquired solely for the Holder’s
own account and not as a nominee for any other party, for investment and not with a view toward distribution or resale and that the Holder shall have confirmed such other matters related thereto as may be reasonably requested by the Company. 

(d)        Securities Law Legend. The Securities shall (unless
otherwise permitted by the provisions of this Warrant) be stamped or imprinted with a legend substantially similar to the following (in addition to any legend required by state securities laws): 

THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”),
OR UNDER THE SECURITIES LAWS OF CERTAIN STATES. THESE SECURITIES MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED EXCEPT AS PERMITTED UNDER THE ACT AND APPLICABLE STATE SECURITIES LAWS IN ACCORDANCE WITH APPLICABLE
REGISTRATION REQUIREMENTS OR AN EXEMPTION THEREFROM. THE ISSUER OF THESE SECURITIES MAY REQUIRE AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE ISSUER THAT SUCH OFFER, SALE OR TRANSFER, PLEDGE OR HYPOTHECATION OTHERWISE COMPLIES WITH THE ACT
AND ANY APPLICABLE STATE SECURITIES LAWS. THIS CERTIFICATE MUST BE SURRENDERED TO THE COMPANY OR ITS TRANSFER AGENT AS A CONDITION PRECEDENT TO THE SALE, TRANSFER, PLEDGE OR HYPOTHECATION OF ANY INTEREST IN ANY OF THE SECURITIES REPRESENTED HEREBY.

 (e)        Market Stand-off
Legend. The Shares issued upon exercise hereof shall also be stamped or imprinted with a legend in substantially the following form: 

THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO RESTRICTIONS ON TRANSFERABILITY AND RESALE, INCLUDING A LOCK-UP PERIOD IN THE EVENT OF A PUBLIC OFFERING, AS SET FORTH IN AN INVESTORS’ RIGHTS AGREEMENT, A COPY OF WHICH MAY BE OBTAINED AT THE PRINCIPAL OFFICE OF THE COMPANY. 

(f)        Instructions Regarding Transfer Restrictions. The Holder
consents to the Company making a notation on its records and giving instructions to any transfer agent in order to implement the restrictions on transfer established in this Section 6. 

(g)        Removal of Legend. The legend referring to federal and state
securities laws identified in Section 6(d) stamped on a certificate evidencing the Shares and the stock transfer instructions and record notations with respect to such securities shall be removed and the Company shall issue a certificate
without such legend to the holder of such securities if (i) such securities are registered under the Securities Act, or (ii) such holder provides the Company with an opinion of counsel reasonably acceptable to the Company to the effect
that a sale or transfer of such securities may be made without registration or qualification.

 7.        Adjustments.
Subject to the expiration of this Warrant pursuant to Section 9, the number and kind of shares purchasable hereunder and the Exercise Price therefor are subject to adjustment from time to time, as follows: 

(a)        Merger or Reorganization. If at any time there shall be any
reorganization, recapitalization, merger or consolidation (a “Reorganization”) involving the Company (other than as otherwise provided for herein or as would cause the expiration of this Warrant under Section 9) 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 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 Common 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 Common
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 Section 7, 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. 

8.        Notification of Certain Events. Prior to the expiration of
this Warrant pursuant to Section 9, in the event that the Company shall authorize: 

(a)        the issuance of any dividend or other distribution on the capital stock of
the Company (other than (i) dividends or distributions otherwise provided for in Section 7, (ii) repurchases of common stock issued to or held by employees, officers, directors or consultants of the Company or its subsidiaries upon
termination of their employment or services pursuant to agreements providing for the right of said repurchase; or (iii) repurchases of common stock issued to or held by employees, officers, directors or consultants of the Company or its
subsidiaries pursuant to rights of first refusal or first offer contained in agreements providing for such rights), whether in cash, property, stock or other securities; 

(b)        the voluntary liquidation, dissolution or winding up of the Company; or


  
 6 













 (c)        any transaction
resulting in the expiration of this Warrant pursuant to Section 9(b) or 9(c); 
 the Company shall send to the Holder of this Warrant
at least ten (10) business days prior written notice of the date on which a record shall be taken for any such dividend or distribution specified in clause (a) or the expected effective date of any such other event specified in
clause (b) or (c), as applicable. The notice provisions set forth in this section may be shortened or waived prospectively or retrospectively by the consent of the Holder of this Warrant. 

9.        Expiration of the Warrant. This Warrant shall expire and shall
no longer be exercisable as of the earlier of: 
 (a)        5:00 p.m., Pacific
time, on the ten (10) year anniversary of the Issue Date; 
 (b)        the
acquisition of the Company by another entity by means of any transaction or series of related transactions to which the Company is a party (including, without limitation, any stock acquisition, reorganization, merger or consolidation, but excluding
any sale of stock for capital raising purposes and any transaction effected primarily for purposes of changing the Company’s jurisdiction of incorporation) other than a transaction or series of related transactions in which the holders of the
voting securities of the Company outstanding immediately prior to such transaction or series of related transactions retain, immediately after such transaction or series of transactions, as a result of shares in the Company held by such holders
prior to such transaction or series of transactions, at least a majority of the total voting power represented by the outstanding voting securities of the Company or such other surviving or resulting entity (or if the Company or such other surviving
or resulting entity is a wholly-owned subsidiary immediately following such acquisition, its parent), or (ii) a sale, lease or other disposition of all or substantially all of the assets of the Company and its subsidiaries taken as a whole by
means of any transaction or series of related transactions, except where such sale, lease or other disposition is to a wholly-owned subsidiary of the Company; or 

(c)        immediately prior to the closing of a firm commitment underwritten initial
public offering pursuant to an effective registration statement filed under the Securities Act covering the offering and sale of the Company’s common stock. 

10.        No Rights as a Stockholder. Nothing contained herein shall
entitle the Holder to any rights as a stockholder of the Company or to be deemed the holder of any securities that may at any time be issuable on the exercise of the rights hereunder for any purpose nor shall anything contained herein be construed
to confer upon the Holder, as such, any right to vote for the election of directors or upon any matter submitted to stockholders at any meeting thereof, or to give or withhold consent to any corporate action (whether upon any recapitalization,
issuance of stock, reclassification of stock, change of par value or change of stock to no par value, consolidation, merger, conveyance or otherwise) or to receive notice of meetings, or to receive dividends or subscription rights or any other
rights of a stockholder of the Company until the rights under the Warrant shall have been exercised and the Shares purchasable upon exercise of the rights hereunder shall have become deliverable as provided herein. 

11.        Representations and Warranties of the Holder. By acceptance
of this Warrant, the Holder represents and warrants to the Company as follows: 

(a)        No Registration. The Holder understands that the Securities
have not been, and will not be, registered under the Securities Act by reason of a specific exemption from the registration provisions of the Securities Act, the availability of which depends upon, among other things, the bona fide nature of
the investment intent and the accuracy of the Holder’s representations as expressed herein or otherwise made pursuant hereto. 

(b)        Investment Intent. The Holder is acquiring the Securities
for investment for its own account, not as a nominee or agent, and not with a view to, or for resale in connection with, any distribution thereof. The Holder has no present intention of selling, granting any participation in, or otherwise
distributing the Securities, nor does it have any contract, undertaking, agreement or arrangement for the same. 

(c)        Investment Experience. The Holder has substantial experience
in evaluating and investing in private placement transactions of securities in companies similar to the Company, and has such knowledge and 

  
 7 













 
experience in financial or business matters so that it is capable of evaluating the merits and risks of its investment in the Company and protecting its own interests. 

(d)        Speculative Nature of Investment. The Holder understands and
acknowledges that its investment in the Company is highly speculative and involves substantial risks. The Holder can bear the economic risk of its investment and is able, without impairing its financial condition, to hold the Securities for an
indefinite period of time and to suffer a complete loss of its investment. 

(e)        Access to Data. The Holder has had an opportunity to ask
questions of officers of the Company, which questions were answered to its satisfaction. The Holder understands that any such discussions, as well as any information issued by the Company, were intended to describe certain aspects of the
Company’s business and prospects, but were not necessarily a thorough or exhaustive description. The Holder acknowledges that any business plans prepared by the Company have been, and continue to be, subject to change and that any projections
included in such business plans or otherwise are necessarily speculative in nature, and it can be expected that some or all of the assumptions underlying the projections will not materialize or will vary significantly from actual results. 

(f)        Accredited Investor. The Holder is an “accredited
investor” within the meaning of Regulation D, Rule 501(a), promulgated by the Securities and Exchange Commission and agrees to submit to the Company such further assurances of such status as may be reasonably requested by the Company.

 (g)        Residency. The residency of the Holder (or, in the case
of a partnership or corporation, such entity’s principal place of business) is correctly set forth on the signature page hereto. 

(h)        Restrictions on Resales. The Holder acknowledges that the
Securities must be held indefinitely unless subsequently registered under the Securities Act or an exemption from such registration is available. The Holder is aware of the provisions of Rule 144 promulgated under the Securities Act, which
permit resale of shares purchased in a private placement subject to the satisfaction of certain conditions, which may include, among other things, the availability of certain current public information about the Company; the resale occurring not
less than a specified period after a party has purchased and paid for the security to be sold; the number of shares being sold during any three-month period not exceeding specified limitations; the sale being effected through a “broker’s
transaction,” a transaction directly with a “market maker” or a “riskless principal transaction” (as those terms are defined in the Securities Act or the Securities Exchange Act of 1934, as amended, and the rules and
regulations promulgated thereunder); and the filing of a Form 144 notice, if applicable. The Holder acknowledges and understands that the Company may not be satisfying the current public information requirement of Rule 144 at the time the
Holder wishes to sell the Securities and that, in such event, the Holder may be precluded from selling the Securities under Rule 144 even if the other applicable requirements of Rule 144 have been satisfied. The Holder acknowledges that,
in the event the applicable requirements of Rule 144 are not met, registration under the Securities Act or an exemption from registration will be required for any disposition of the Securities. The Holder understands that, although
Rule 144 is not exclusive, the Securities and Exchange Commission has expressed its opinion that persons proposing to sell restricted securities received in a private offering other than in a registered offering or pursuant to Rule 144
will have a substantial burden of proof in establishing that an exemption from registration is available for such offers or sales and that such persons and the brokers who participate in the transactions do so at their own risk. 

(i)        No Public Market. The Holder understands and acknowledges
that no public market now exists for any of the securities issued by the Company and that the Company has made no assurances that a public market will ever exist for the Company’s securities. 

(j)        Brokers and Finders. The Holder has not engaged any brokers,
finders or agents in connection with the Securities, and the Company has not incurred nor will incur, directly or indirectly, as a result of any action taken by the Holder, any liability for brokerage or finders’ fees or agents’
commissions or any similar charges in connection with the Securities. 

(k)        Legal Counsel. The Holder has had the opportunity to review
this Warrant, the exhibits and schedules attached hereto and the transactions contemplated by this Warrant with its own legal counsel. The Holder is 

  
 8 













 
not relying on any statements or representations of the Company or its agents for legal advice with respect to this investment or the transactions contemplated by this Warrant. 

(l)        Tax Advisors. The Holder has reviewed with its own tax
advisors the U.S. federal, state and local and non-U.S. tax consequences of this investment and the transactions contemplated by this Warrant. With respect to such matters, the Holder relies solely on any such
advisors and not on any statements or representations of the Company or any of its agents, written or oral. The Holder understands that it (and not the Company) shall be responsible for its own tax liability that may arise as a result of this
investment and the transactions contemplated by this Warrant. 

12.        Miscellaneous. 

(a)        Amendments. Except as expressly provided herein, neither
this Warrant nor any term hereof may be amended, waived, discharged or terminated other than by a written instrument referencing this Warrant and the Holder. 

(b)        Waivers. No waiver of any single breach or default shall be
deemed a waiver of any other breach or default theretofore or thereafter occurring.

INVESTMENT REPRESENTATION STATEMENT 
  

							
	 INVESTOR:
	  	 [______]
	 	   

			
	 COMPANY:
	  	 DERMTECH INTERNATIONAL
	 	
			
	 SECURITIES:
	  	 THE WARRANT ISSUED ON ________________________ (THE “WARRANT”) AND THE SECURITIES
ISSUED OR ISSUABLE UPON EXERCISE THEREOF
	 	
			
	 DATE:
	  	  
	 	

 In connection with the purchase or acquisition of the above-listed Securities, the undersigned
Investor represents and warrants to, and agrees with, the Company as follows: 

1.        No Registration. The Investor understands that the Securities
have not been, and will not be, registered under the Securities Act of 1933, as amended (the “Securities Act”), by reason of a specific exemption from the registration provisions of the Securities Act, the availability of
which depends upon, among other things, the bona fide nature of the investment intent and the accuracy of the Investor’s representations as expressed herein or otherwise made pursuant hereto. 

2.        Investment Intent. The Investor is acquiring the Securities for
investment for its own account, not as a nominee or agent, and not with a view to, or for resale in connection with, any distribution thereof. The Investor has no present intention of selling, granting any participation in, or otherwise distributing
the Securities, nor does it have any contract, undertaking, agreement or arrangement for the same. 

3.        Investment Experience. The Investor has substantial experience
in evaluating and investing in private placement transactions of securities in companies similar to the Company, and has such knowledge and experience in financial or business matters so that it is capable of evaluating the merits and risks of its
investment in the Company and protecting its own interests. 

4.        Speculative Nature of Investment. The Investor understands and
acknowledges that its investment in the Company is highly speculative and involves substantial risks. The Investor can bear the economic risk of its investment and is able, without impairing its financial condition, to hold the Securities for an
indefinite period of time and to suffer a complete loss of its investment. 

5.        Access to Data. The Investor has had an opportunity to ask
questions of officers of the Company, which questions were answered to its satisfaction. The Investor understands that any such discussions, as well as any information issued by the Company, were intended to describe certain aspects of the
Company’s business and prospects, but were not necessarily a thorough or exhaustive description. The Investor acknowledges that any business plans prepared by the Company have been, and continue to be, subject to change and that any projections
included in such business plans or otherwise are necessarily speculative in nature, and it can be expected that some or all of the assumptions underlying the projections will not materialize or will vary significantly from actual results. 

6.        Accredited Investor. The Investor is an “accredited
investor” within the meaning of Regulation D, Rule 501(a), promulgated by the Securities and Exchange Commission and agrees to submit to the Company such further assurances of such status as may be reasonably requested by the Company.

 7.        Residency. The residency of the Investor (or, in the case
of a partnership or corporation, such entity’s principal place of business) is correctly set forth on the signature page hereto. 

8.        Restrictions on Resales. The Investor acknowledges that the
Securities must be held indefinitely unless subsequently registered under the Securities Act or an exemption from such registration is available. The Investor is aware of the provisions of Rule 144 promulgated under the Securities Act, which
permit resale of shares purchased in 












 
a private placement subject to the satisfaction of certain conditions, which may include, among other things, the availability of certain current public information about the Company; the resale
occurring not less than a specified period after a party has purchased and paid for the security to be sold; the number of shares being sold during any three-month period not exceeding specified limitations; the sale being effected through a
“broker’s transaction,” a transaction directly with a “market maker” or a “riskless principal transaction” (as those terms are defined in the Securities Act or the Securities Exchange Act of 1934, as amended, and
the rules and regulations promulgated thereunder); and the filing of a Form 144 notice, if applicable. The Investor acknowledges and understands that the Company may not be satisfying the current public information requirement of Rule 144 at
the time the Investor wishes to sell the Securities and that, in such event, the Investor may be precluded from selling the Securities under Rule 144 even if the other applicable requirements of Rule 144 have been satisfied. The Investor
understands and acknowledges that, in the event the applicable requirements of Rule 144 are not met, registration under the Securities Act or an exemption from registration will be required for any disposition of the Securities. The Investor
understands that, although Rule 144 is not exclusive, the Securities and Exchange Commission has expressed its opinion that persons proposing to sell restricted securities received in a private offering other than in a registered offering or
pursuant to Rule 144 will have a substantial burden of proof in establishing that an exemption from registration is available for those offers or sales and that those persons and the brokers who participate in the transactions do so at their
own risk. 
 9.        No Public Market. The Holder understands and
acknowledges that no public market now exists for any of the securities issued by the Company and that the Company has made no assurances that a public market will ever exist for the Company’s securities. 

10.        Brokers and Finders. The Investor has not engaged any
brokers, finders or agents in connection with the Securities, and the Company has not incurred nor will incur, directly or indirectly, as a result of any action taken by the Investor, any liability for brokerage or finders’ fees or agents’
commissions or any similar charges in connection with the Securities. 

11.        Legal Counsel. The Investor has had the opportunity to review
the Warrant, the exhibits and schedules attached thereto and the transactions contemplated by the Warrant with its own legal counsel. The Investor is not relying on any statements or representations of the Company or its agents for legal advice with
respect to this investment or the transactions contemplated by the Warrant. 

12.        Tax Advisors. The Investor has reviewed with its own tax
advisors the U.S. federal, state and local and non-U.S. tax consequences of this investment and the transactions contemplated by the Warrant. With respect to such matters, the Investor relies solely on such
advisors and not on any statements or representations of the Company or any of its agents, written or oral. The Investor understands that it (and not the Company) shall be responsible for its own tax liability that may arise as a result of this
investment or the transactions contemplated by the Warrant.
