	No. CSW-11	  	September 10, 2013

 THIS CERTIFIES THAT, for value
received, ARE-SD Region No. 18, LLC or its assigns (collectively, the “Holder”), is entitled to subscribe for and purchase at the Exercise Price (defined below) from BIOCEPT,
INC., a Delaware corporation (the “Company”), up to such number of fully paid and nonassessable shares of Common Stock of the Company as set forth herein, during the Exercise Period (as
defined below). 
 1. DEFINITIONS. As used herein, the following terms shall have the following respective
meanings: 
 (a) “Exercise Period” shall mean the period commencing on the date of the closing of
a firmly underwritten public offering pursuant to an effective registration statement under the Securities Act of 1933, as amended, covering the offer and sale of the Company’s Common Stock for the account of the Company (the
“IPO”) and ending five (5) years thereafter, unless sooner terminated as provided below. 
 (b)
“Exercise Price” shall mean the per share purchase price of the Company’s Common Stock sold in the IPO. 
 (c) “Exercise Shares” shall mean the Company’s Common Stock. 
 (d) “Warrant Coverage Amount” shall be $502,605. 

2. NUMBER OF SHARES. The number of Exercise Shares for up to which this Warrant may
be exercisable is equal to the quotient (rounded down to the nearest whole share) of the Warrant Coverage Amount divided by the Exercise Price, subject to adjustment as provided in Section 6 below. 

3. EXERCISE OF WARRANT. The rights represented by this Warrant may be exercised in
whole or in part at any time during the Exercise Period, by delivery of the following to the Company at its address set forth on the signature page hereto (or at such other address as it may designate by notice in writing to the Holder): 

(a) An executed Notice of Exercise in the form attached hereto; 

(b) Payment of the Exercise Price either (i) in cash or by check, (ii) by cancellation of indebtedness, or
(iii) any combination thereof; and 
 (c) This Warrant. 

Upon the exercise of the rights represented by this Warrant, a certificate or certificates for the Exercise Shares so purchased,
registered in the name of the Holder or persons affiliated with the Holder, if the Holder so designates, shall be issued and delivered to the Holder within a reasonable time after the rights represented by this Warrant shall have been so exercised.

  
 1 

 The person in whose name any certificate or certificates for Exercise Shares are to be
issued upon exercise of this Warrant shall be deemed to have become the holder of record of such shares on the date on which this Warrant was surrendered and payment of the Exercise Price was made, irrespective of the date of delivery of such
certificate or certificates, except that, if the date of such surrender and payment is a date when the stock transfer books of the Company are closed, such person shall be deemed to have become the holder of such shares at the close of business on
the next succeeding date on which the stock transfer books are open. 
 The Holder, in lieu of exercising this Warrant by the
payment of the Exercise Price by a method described above, may elect, at any time during the Exercise Period, to surrender this Warrant and receive the number of Exercise Shares computed using the following formula: 

X = [(A-B) (Y)] / B 
 Where: 
 X = the number of Exercise Shares to be issued to the Holder. 

Y = the number of Exercise Shares that the Holder would otherwise have been entitled to purchase hereunder (or such lesser number of
Exercise Shares as the Holder may designate in the case of a partial exercise of this Warrant). 
 A = the Per Share Price (as
defined below) at the time the net issuance election under this Section 3 is made. 
 B = the Exercise Price then in
effect. 
 Election to “net exercise” may be made by delivering to the Company at its address set forth on the
signature page hereto (or at such other address as it may designate by notice in writing to the Holder) an executed Notice of Exercise in the form attached hereto (with the indicated “net exercise” box checked) either physically and
accompanied by this Warrant (in which case exercise shall be deemed to occur on the day the Company receives such materials) or via scan/email, followed by overnight delivery of the originals (in which case exercise shall be deemed to occur on the
day of the email, provided that the email is received before 1:00 p.m. (Pacific time) on the day of the email and the Company receives the originals on the following business day). Notwithstanding anything to the contrary contained in this Warrant,
if as of the close of business on the last business day preceding the expiration of the Exercise Period this Warrant remains unexercised as to all or a portion of the number of Exercise Shares purchasable hereunder, then effective as 9:00 a.m.
(Pacific time) on such expiration date, the Holder shall be deemed, automatically and without need for notice to the Company, to have elected to “net exercise” this Warrant in full using the above formula, provided that the application of
such formula as of such expiration date yields a positive number for “X”. 
 “Per Share Price” means:

 (i) If this Warrant is exercised on the date of the IPO, and if the Company’s registration statement relating to such IPO
has been declared effective by the Securities and Exchange Commission, then the Per Share Price shall be the initial “Price to Public” of the Common Stock specified in the final prospectus with respect to the IPO; 

(ii) If this Warrant is exercised after, and not on the date of, the IPO, and if the Company’s Common Stock is traded on a
securities exchange or actively traded over-the-counter: 
 (a) If the Company’s Common Stock is traded on a national
securities exchange, the Per Share Price shall be deemed to be the closing price of the Company’s Common Stock as quoted on any national securities exchange, as published on Yahoo! Finance (or a successor thereto or equivalent publisher) for
the trading day immediately before the date of the Holder’s election hereunder and 

  
 2 

 (b) If the Company’s Common Stock is actively traded over-the-counter (but is not
quoted on any national securities exchange), the Per Share Price shall be deemed to be the closing bid or sales price, whichever is applicable, of the Company’s Common Stock for the trading day immediately before the date of the Holder’s
election hereunder; 
 (iii) If neither (i) nor (ii) is applicable, the Per Share Price shall be determined in good
faith by the Board of Directors of the Company based on relevant facts and circumstances at the time of the net exercise. 

4. REPRESENTATIONS OF THE HOLDER. 

4.1 Acquisition of Warrant for Personal Account. The Holder represents and warrants that it is acquiring this Warrant and the
Exercise Shares solely for its account for investment and not with a view to or for sale or distribution of said Warrant or Exercise Shares or any part thereof. The Holder also represents that the entire legal and beneficial interests of this
Warrant and Exercise Shares the Holder is acquiring is being acquired for, and will be held for, its account only.

4.3 Ability to Bear Economic Risk. Holder acknowledges that investment in the securities of the Company involves a high degree of

4.4 Securities Are Not Registered. 
 (a) The Holder understands that this Warrant and the Exercise Shares have not been registered under the Securities Act on the basis that no distribution or public offering of the stock of the
Company is to be effected. The Holder realizes that the basis for the exemption may not be present if, notwithstanding its representations, the Holder has a present intention of acquiring the securities for a fixed or determinable period in the
future, selling (in connection with a distribution or otherwise), granting any participation in, or otherwise distributing the securities. The Holder has no such present intention. 

(b) The Holder recognizes that this Warrant and the Exercise Shares must be held indefinitely unless they are subsequently

registration. 
 4.5 Disposition of Warrant and Exercise Shares. 

(a) The Holder further agrees not to make any disposition of all or any part of this Warrant or Exercise Shares in any event
unless and until: 
 (i) The Company shall have received a letter secured by the Holder from the Securities and Exchange
Commission stating that no action will be recommended to the Commission with respect to the proposed disposition; 

  
 3 

 (ii) There is then in effect a registration statement under the Securities Act
covering such proposed disposition and such disposition is made in accordance with said registration statement; or 
 (iii)
The Holder shall have notified the Company of the proposed disposition and shall have furnished the Company with a detailed statement of the circumstances surrounding the proposed disposition, and if reasonably requested by the Company, the
Holder shall have furnished the Company with an opinion of counsel, reasonably satisfactory to the Company, for the Holder to the effect that such disposition will not require registration of this Warrant or Exercise Shares under the Securities Act
or any applicable state securities laws. The Company agrees that it will not require an opinion of counsel with respect to transactions under Rule 144 of the Securities Act, except in unusual circumstances. 

(b) The Holder understands and agrees that all certificates evidencing the shares to be issued to the Holder may bear the
following legend: 
 THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE
“ACT”). THEY MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED OR HYPOTHECATED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT AS TO THE SECURITIES UNDER THE ACT OR AN OPINION OF COUNSEL SATISFACTORY TO THE COMPANY THAT SUCH
REGISTRATION IS NOT REQUIRED. 
 4.6 Accredited Investor Status. The Holder is an accredited investor or is represented
by a purchaser representative within the meaning of Regulation D under the Securities Act. 
 5. COVENANTS
OF THE COMPANY. 
 5.1 Covenants as to Exercise Shares. The Company
covenants and agrees that all Exercise Shares that may be issued upon the exercise of the rights represented by this Warrant will, upon issuance, be validly issued and outstanding, fully paid and nonassessable, and free from all taxes, liens and
charges with respect to the issuance thereof. The Company further covenants and agrees that the Company will at all times during the Exercise Period, have authorized and reserved, free from preemptive rights, a sufficient number of shares to provide
for the exercise of the rights represented by this Warrant. If at any time during the Exercise Period the number of authorized but unissued shares is not sufficient to permit exercise of this Warrant, the Company will take such corporate action as
may, in the opinion of its counsel, be necessary to increase its authorized but unissued shares to such number of shares as shall be sufficient for such purposes. 
 5.2 No Impairment. Except and to the extent as waived or consented to by the Holder, the Company will not, by amendment of its Amended and Restated Articles 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 of this Warrant and in the taking of all such action as may be necessary or appropriate in order to protect the exercise rights of the Holder against
impairment. 
 6. ADJUSTMENT OF EXERCISE PRICE. In the event
of changes in the outstanding Common Stock of the Company by reason of stock dividends, split-ups, recapitalizations, reclassifications, combinations or exchanges of shares, separations, reorganizations, liquidations, or the like, the number and
class of shares available under the Warrant in the aggregate and the Exercise Price shall be correspondingly adjusted to give the Holder of the Warrant, on exercise for the same aggregate Exercise Price, the total number, class, and kind of shares
as the Holder would have owned had the Warrant been exercised before the event and had the Holder continued to hold such shares until after the event requiring adjustment; provided, however, that such adjustment shall not be made with respect
to, and this Warrant shall terminate if not exercised before, the events set forth in Section 8 below. The form of this Warrant need not be changed because of any adjustment in the number of Exercise Shares subject to this Warrant. 

  
 4 

 7. FRACTIONAL SHARES. No fractional shares shall be
issued upon the exercise of this Warrant as a consequence of any adjustment pursuant hereto. All Exercise Shares (including fractions) issuable upon exercise of this Warrant may be aggregated for purposes of determining whether the exercise would
result in the issuance of any fractional share. If, after aggregation, the exercise would result in the issuance of a fractional share, the Company shall, in lieu of issuance of any fractional share, pay the Holder otherwise entitled to such
fraction a sum in cash equal to the product resulting from multiplying the then current fair market value of an Exercise Share by such fraction. 
 8. EARLY TERMINATION. In the event of, at any time during the Exercise Period, any capital reorganization, or any reclassification of the capital stock of the Company
(other than a change in par value or from par value to no par value or no par value to par value or as a result of a stock dividend or subdivision, split-up or combination of shares), or an Asset Transfer or Acquisition (as defined in the
Company’s Amended and Restated Articles of Incorporation, as amended) (other than a merger solely to effect a reincorporation of the Company into another state), the Company shall provide to the Holder 20 days advance written notice of such
reorganization, reclassification, consolidation, merger or sale or other disposition of the Company’s assets, and this Warrant shall terminate unless exercised before the occurrence of such reorganization, reclassification, consolidation,
merger or sale or other disposition of the Company’s assets. 
 9. MARKET
STAND-OFF AGREEMENT. Holder shall not sell, dispose of, transfer, make any short sale of, grant any option for the purchase of, or enter into any hedging or similar transaction with the same economic
effect as a sale with respect to, any Common Stock (or other securities) of the Company held by such Holder, for a period of time specified by the managing underwriter(s) not to exceed 180 days following the effective date of a registration
statement of the Company filed under the Securities Act in connection with the IPO (or such longer period, not to exceed 34 days after the expiration of the 180-day period, as the underwriters or the Company shall request in order to facilitate
compliance with NASD Rule 2711 or NYSE Member Rule 472 or any successor or similar rule or regulation). Holder agrees to execute and deliver such other agreements as may be reasonably requested by the Company and/or the managing underwriter(s) which
are consistent with the foregoing or which are necessary to give further effect thereto. In order to enforce the foregoing covenant, the Company may impose stop-transfer instructions with respect to such Common Stock (or other securities) until the
end of such period. Each Holder agrees that any transferee of Common Stock (or other securities) shall be bound by this Section 9. The underwriters of the Company’s stock are intended third party beneficiaries of this Section 9 and
shall have the right, power and authority to enforce the provisions hereof as though they were a party hereto. 
 10.
NO SHAREHOLDER RIGHTS. This Warrant in and of itself shall not entitle the Holder to any voting rights or other rights as a shareholder of the Company. 

11. TRANSFER OF WARRANT. Subject to applicable laws and the restrictions on transfer
set forth in this Warrant, this Warrant and all rights hereunder are transferable, by the Holder in person or by duly authorized attorney, upon delivery of this Warrant and the form of assignment attached hereto to any transferee designated by
Holder. The transferee shall sign an investment letter in form and substance satisfactory to the Company. 
 12.
LOST, STOLEN, MUTILATED OR DESTROYED WARRANT. If this Warrant is lost, stolen, mutilated or destroyed, the Company may, on such terms as to indemnity or
otherwise as it may reasonably impose (which shall, in the case of a mutilated Warrant, include the surrender thereof), issue a new Warrant of like denomination and tenor as the Warrant so lost, stolen, mutilated or destroyed. Any such new Warrant
shall constitute an original contractual obligation of the Company, whether or not the allegedly lost, stolen, mutilated or destroyed Warrant shall be at any time enforceable by anyone. 

13. NOTICES, ETC. All notices required or permitted hereunder shall be in writing and shall be
deemed effectively given: (a) upon personal delivery to the party to be notified, (b) when sent by confirmed facsimile if sent during normal business hours of the recipient, if not, then on the next business day, (c) five days after
having been sent by registered or certified mail, return receipt requested, postage prepaid, or (d) one day after deposit with a nationally recognized overnight courier, specifying next day delivery, with written verification of receipt. All
communications shall be sent to the Company and the Holder at the address set forth on the signature 

  
 5 

 
page hereto, or at such other address as the Company or Holder may designate by 10 days advance written notice to the other party hereto. 

14. ACCEPTANCE. Receipt of this Warrant by the Holder shall constitute acceptance of and agreement to all of the
terms and conditions contained herein. 
 15. COUNTERPARTS. This Warrant may be executed in counterparts,
each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. 
 16.
GOVERNING LAW. This Warrant shall be governed by, and construed and enforced in accordance with, the laws of the State of California, applied to agreements between California residents, made to be performed entirely
within the State of California, without giving effect to conflicts of law principles.

RECEIVED AN OPINION OF COUNSEL SATISFACTORY TO THE COMPANY AND ITS COUNSEL THAT SUCH REGISTRATION IS NOT REQUIRED.

any such registration statement all or any part of the Registrable Securities held by it shall, within 15 days after the above-described notice from the Company, so notify the Company in writing. Such notice shall state the intended method of
disposition of the Registrable Securities by such Holder. If a Holder decides not to include all of its Registrable Securities in any registration statement thereafter filed by the Company, such Holder shall nevertheless continue to have the right

Holders of Registrable Securities. In such event, the right of any such Holder to include Registrable Securities in a registration pursuant to this Section 2.2 shall be conditioned upon such
Holder’s participation in such underwriting and the inclusion of such Holder’s Registrable Securities in the underwriting to the extent provided herein. All Holders proposing to distribute their Registrable Securities through such
underwriting shall enter into an underwriting agreement in customary form with the underwriter or underwriters selected for such underwriting by the Company. Notwithstanding any other provision of this Agreement, if the underwriter determines in
good faith that marketing factors require a limitation of the number of shares to be underwritten, the number of shares that may be included in the underwriting shall be allocated, first, to the Company; second, to the Holders on a pro rata
basis based on the total number of Registrable Securities held by the Holders; and third, to any shareholder of the Company (other than a Holder) on a pro rata basis. In no event will shares of any other selling shareholder be included in
such registration that would reduce the number of shares which may be included by Holders without the written consent of Holders of not less than a majority of the Registrable Securities proposed to be sold in the offering. If any Holder disapproves
of the terms of any such underwriting, such Holder may elect to withdraw therefrom by written notice to the Company and the underwriter, delivered at least 10 business days prior to the effective date of the registration statement. Any Registrable
Securities excluded or withdrawn from such underwriting shall be excluded and withdrawn from the registration. For any Holder which is a partnership, limited liability company or corporation, the partners, retired partners, members, retired members
and stockholders of such Holder, or the estates and family members of any such partners, retired partners, members and retired members and any trusts for the benefit of any of the foregoing person shall be deemed to be a single “Holder,”
and any pro rata reduction with respect to such “Holder” shall be based upon the aggregate amount of shares carrying registration rights owned by all entities and individuals included in such “Holder,” as defined in this
sentence. 
 (b) Right to Terminate Registration. The Company shall have the right to terminate or withdraw any
registration initiated by it under this Section 2.2 whether or not any Holder has elected to include securities in such registration, and shall promptly notify any Holder that has elected to include shares in such registration of such
termination or withdrawal. The Registration Expenses of such withdrawn registration shall be borne by the Company in accordance with Section 2.3 hereof. 
 2.3 Expenses of Registration. Except as specifically provided herein, all Registration Expenses incurred in connection with any registration, qualification or compliance pursuant to
Section 2.2 herein shall be borne by the Company. All Selling Expenses incurred in connection with any registrations hereunder, shall be borne by the holders of the securities so registered pro rata on the basis of the
number of shares so registered. 
 2.4 Obligations of the Company. Whenever required to effect the registration of
any Registrable Securities, the Company shall, as expeditiously as reasonably possible: 
 (a) Prepare and file
with the SEC such amendments and supplements to the registration statement and the prospectus used in connection with such registration statement as may be necessary to comply with the provisions of the Securities Act with respect to the disposition
of all securities covered by such registration statement. 

  
 5. 

 (b) Furnish to the Holders such number of copies of a prospectus, including a
preliminary prospectus, in conformity with the requirements of the Securities Act, and such other documents as they may reasonably request in order to facilitate the disposition of Registrable Securities owned by them. 

(c) Use its reasonable efforts to register and qualify the securities covered by such registration statement under such other
securities or Blue Sky laws of such jurisdictions as shall be reasonably requested by the Holders; provided that the Company shall not be required in connection therewith or as a condition thereto to qualify to do business or to file a
general consent to service of process in any such states or jurisdictions. 
 (d) In the event of any underwritten public
offering, enter into and perform its obligations under an underwriting agreement, in usual and customary form, with the managing underwriter(s) of such offering. Each Holder participating in such underwriting shall also enter into and perform its
obligations under such an agreement. 
 (e) Notify each Holder of Registrable Securities covered by such registration
statement at any time when a prospectus relating thereto is required to be delivered under the Securities Act of the happening of any event as a result of which the prospectus included in such registration statement, as then in effect, includes an
untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing. The Company will use reasonable efforts
to amend or supplement such prospectus in order to cause such prospectus not to include any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading
in the light of the circumstances then existing. 
 (f) Use its reasonable efforts to furnish, on the date that such
Registrable Securities are delivered to the underwriters for sale, if such securities are being sold through underwriters, (i) an opinion, dated as of such date, of the counsel representing the Company for the purposes of such registration, in
form and substance as is customarily given to underwriters in an underwritten public offering, addressed to the underwriters, if any, and (ii) a letter, dated as of such date, from the independent certified public accountants of the Company, in
form and substance as is customarily given by independent certified public accountants to underwriters in an underwritten public offering addressed to the underwriters. 
 2.5 Delay of Registration; Furnishing Information. 
 (a) No Holder
shall have any right to obtain or seek an injunction restraining or otherwise delaying any such registration as the result of any controversy that might arise with respect to the interpretation or implementation of this Section 2. 

(b) It shall be a condition precedent to the obligations of the Company to take any action pursuant to Section 2.2 that the
selling Holders shall furnish to the Company such information regarding themselves, the Registrable Securities held by them and the intended method of disposition of such securities as shall be required to effect the registration of their
Registrable Securities. 

  
 6. 

 2.6 Indemnification. In the event any Registrable Securities are included in a
registration statement under Sections 2.2: 
 (a) To the extent permitted by law, the Company will indemnify and hold
harmless each Holder, the partners, members, officers and directors of each Holder, any underwriter (as defined in the Securities Act) for such Holder and each person, if any, who controls such Holder or underwriter within the meaning of the
Securities Act or the Exchange Act, against any losses, claims, damages, or liabilities (joint or several) to which they may become subject under the Securities Act, the Exchange Act or other federal or state law, insofar as such losses, claims,
damages or liabilities (or actions in respect thereof) arise out of or are based upon any of the following statements, omissions or violations (collectively a “Violation”) by the Company: (i) any untrue statement or
alleged untrue statement of a material fact contained in such registration statement or incorporated reference therein, including any preliminary prospectus or final prospectus contained therein or any amendments or supplements thereto,
(ii) the omission or alleged omission to state therein a material fact required to be stated therein, or necessary to make the statements therein not misleading, or (iii) any violation or alleged violation by the Company of the Securities
Act, the Exchange Act, any state securities law or any rule or regulation promulgated under the Securities Act, the Exchange Act or any state securities law in connection with the offering covered by such registration statement; and the Company will
reimburse each such Holder, partner, member, officer, director, underwriter or controlling person for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or
action; provided however, that the indemnity agreement contained in this Section 2.6(a) shall not apply to amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected without the consent of the
Company, which consent shall not be unreasonably withheld, nor shall the Company be liable in any such case for any such loss, claim, damage, liability or action to the extent that it arises out of or is based upon a Violation which occurs in
reliance upon and in conformity with written information furnished expressly for use in connection with such registration by such Holder, partner, member, officer, director, underwriter or controlling person of such Holder. 

(b) To the extent permitted by law, each Holder will, if Registrable Securities held by such Holder are included in the securities
as to which such registration qualifications or compliance is being effected, indemnify and hold harmless the Company, each of its directors, its officers and each person, if any, who controls the Company within the meaning of the Securities Act,
any underwriter and any other Holder selling securities under such registration statement or any of such other Holder’s partners, directors or officers or any person who controls such Holder, against any losses, claims, damages or liabilities
(joint or several) to which the Company or any such director, officer, controlling person, underwriter or other such Holder, or partner, director, officer or controlling person of such other Holder may become subject under the Securities Act, the
Exchange Act or other federal or state law, insofar as such losses, claims, damages or liabilities (or actions in respect thereto) arise out of or are based upon any of the following statements: (i) any untrue statement or alleged untrue
statement of a material fact contained in such registration statement or incorporated reference therein, including any preliminary prospectus or final prospectus contained therein or any amendments or supplements thereto, (ii) the omission or
alleged omission to state therein a material fact required to be stated therein, or necessary to make the statements therein not misleading, or (iii) any violation or 

  
 7. 

 
alleged violation by the Company of the Securities Act (collectively, a “Holder Violation”), in each case to the extent (and only to the extent) that such Holder Violation
occurs in reliance upon and in conformity with written information furnished by such Holder under an instrument duly executed by such Holder and stated to be specifically for use in connection with such registration; and each such Holder will
reimburse any legal or other expenses reasonably incurred by the Company or any such director, officer, controlling person, underwriter or other Holder, or partner, officer, director or controlling person of such other Holder in connection with
investigating or defending any such loss, claim, damage, liability or action if it is judicially determined that there was such a Holder Violation; provided, however, that the indemnity agreement contained in this Section 2.6(b) shall
not apply to amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected without the consent of the Holder, which consent shall not be unreasonably withheld; provided further, that in no
event shall any indemnity under this Section 2.6 exceed the net proceeds from the offering received by such Holder. 

(c) Promptly after receipt by an indemnified party under this Section 2.6 of notice of the commencement of any action
(including any governmental action), such indemnified party will, if a claim in respect thereof is to be made against any indemnifying party under this Section 2.6, deliver to the indemnifying party a written notice of the commencement thereof
and the indemnifying party shall have the right to participate in, and, to the extent the indemnifying party so desires, jointly with any other indemnifying party similarly noticed, to assume the defense thereof with counsel mutually satisfactory to
the parties; provided, however, that an indemnified party shall have the right to retain its own counsel, with the fees and expenses thereof to be paid by the indemnifying party, if representation of such indemnified party by the counsel
retained by the indemnifying party would be inappropriate due to actual or potential differing interests between such indemnified party and any other party represented by such counsel in such proceeding. The failure to deliver written notice to the
indemnifying party within a reasonable time of the commencement of any such action shall relieve such indemnifying party of any liability to the indemnified party under this Section 2.6 to the extent, and only to the extent, prejudicial to its
ability to defend such action, but the omission so to deliver written notice to the indemnifying party will not relieve it of any liability that it may have to any indemnified party otherwise than under this Section 2.6. 

(d) If the indemnification provided for in this Section 2.6 is held by a court of competent jurisdiction to be unavailable to
an indemnified party with respect to any losses, claims, damages or liabilities referred to herein, the indemnifying party, in lieu of indemnifying such indemnified party thereunder, shall to the extent permitted by applicable law contribute to the
amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and of the indemnified party on the
other in connection with the Violation(s) or Holder Violation(s) that resulted in such loss, claim, damage or liability, as well as any other relevant equitable considerations. The relative fault of the indemnifying party and of the indemnified
party shall be determined by a court of law by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission to state a material fact relates to information supplied by the indemnifying party or
by the indemnified party and the parties’ relative intent, knowledge, access to information and opportunity to correct 

  
 8. 

 
or prevent such statement or omission; provided, that in no event shall any contribution by a Holder hereunder exceed the net proceeds from the offering received by such Holder.

 (e) The obligations of the Company and Holders under this Section 2.6 shall survive completion of any offering of
Registrable Securities in a registration statement and, with respect to liability arising from an offering to which this Section 2.6 would apply that is covered by a registration filed before termination of this Agreement, such termination. No
indemnifying party, in the defense of any such claim or litigation, shall, except with the consent of each indemnified party, consent to entry of any judgment or enter into any settlement which does not include as an unconditional term thereof the
giving by the claimant or plaintiff to such Indemnified Party of a release from all liability in respect to such claim or litigation. 
 2.7 Assignment of Registration Rights. The rights to piggyback registration rights pursuant to Section 2.2 may be assigned by a Holder to a transferee or assignee of Registrable Securities
(for so long as such shares remain Registrable Securities) that (a) is a subsidiary, parent, general partner, limited partner, retired partner, member or retired member of a Holder that is a corporation, partnership or limited liability
company, (b) is a Holder’s family member or trust for the benefit of an individual Holder, or (c) acquires at least 100,000 shares of Registrable Securities (as adjusted for stock splits and combinations); provided,
however, (i) the transferor shall, within 10 days after such transfer, furnish to the Company written notice of the name and address of such transferee or assignee and the securities with respect to which such registration rights are
being assigned and (ii) such transferee shall agree to be subject to all restrictions set forth in this Agreement. 

2.8 Limitation on Subsequent Registration Rights. After the date of this Agreement, the Company shall not enter into any agreement
with any holder or prospective holder of any securities of the Company that would grant such holder rights to demand the registration of shares of the Company’s capital stock, or to include such shares in a registration statement that would
reduce the number of shares includable by the Holders. 
 2.9 “Market Stand-Off” Agreement. Each Holder
hereby agrees that such Holder shall not sell, transfer, make any short sale of, grant any option for the purchase of, or enter into any hedging or similar transaction with the same economic effect as a sale, any Common Stock (or other securities)
of the Company held by such Holder (other than those included in the registration) during (i) the 180-day period following the effective date of the Initial Offering (or such longer period as the underwriters or the Company shall request in
order to facilitate compliance with NASD Rule 2711 or NYSE Member Rule 472 or any successor or similar rule or regulation), and (ii) the 90-day period following the effective date of a registration statement of the Company filed under the
Securities Act (or such longer period as the underwriters or the Company shall request in order to facilitate compliance with NASD Rule 2711 or NYSE Member Rule 472 or any successor or similar rule or regulation); provided, that, with respect to
(i) and (ii) above, all officers and directors of the Company are bound by and have entered into similar agreements. The obligations described in this Section 2.9 shall not apply to a registration relating solely to employee benefit
plans on Form S-1 or Form S-8 or similar forms that may be promulgated in the future, or a registration relating solely to a transaction on Form S-4 or similar forms that may be promulgated in the future. 

  
 9. 

 2.10 Agreement to Furnish Information. Each Holder agrees to execute and deliver such
other agreements as may be reasonably requested by the Company or the underwriter that are consistent with the Holder’s obligations under Section 2.9 or that are necessary to give further effect thereto. In addition, if requested by the
Company or the representative of the underwriters of Common Stock (or other securities) of the Company, each Holder shall provide, within 10 days of such request, such information as may be required by the Company or such representative in
connection with the completion of any public offering of the Company’s securities pursuant to a registration statement filed under the Securities Act. The obligations described in Section 2.9 and this Section 2.10 shall not apply to a
Special Registration Statement. The Company may impose stop-transfer instructions with respect to the shares of Common Stock (or other securities) subject to the foregoing restriction until the end of said day period. Each Holder agrees that any
transferee of any shares of Registrable Securities shall be bound by Sections 2.9 and 2.10. The underwriters of the Company’s stock are intended third party beneficiaries of Sections 2.9 and 2.10 and shall have the right, power and
authority to enforce the provisions hereof as though they were a party hereto. 
 2.11 Rule 144 Reporting. With a
view to making available to the Holders the benefits of certain rules and regulations of the SEC which may permit the sale of the Registrable Securities to the public without registration, the Company agrees to use its best efforts to:

 (a) Make and keep public information available, as those terms are understood and defined in SEC Rule 144 or
any similar or analogous rule promulgated under the Securities Act, at all times after the effective date of the first registration filed by the Company for an offering of its securities to the general public; 

(b) File with the SEC, in a timely manner, all reports and other documents required of the Company under the Exchange Act; and

 (c) So long as a Holder owns any Registrable Securities, furnish to such Holder forthwith upon request: a written
statement by the Company as to its compliance with the reporting requirements of said Rule 144 of the Securities Act, and of the Exchange Act (at any time after it has become subject to such reporting requirements); a copy of the most recent annual
or quarterly report of the Company filed with the Commission; and such other reports and documents as a Holder may reasonably request in connection with availing itself of any rule or regulation of the SEC allowing it to sell any such securities
without registration. 
 2.12 Termination of Registration Rights. The right of any Holder to request inclusion of
Registrable Securities in any registration pursuant to Section 2.2 hereof shall terminate upon the earlier of: (i) the date three years following an initial public offering that results in the conversion of all outstanding shares of Series
A Stock; or (ii) such time as all Registrable Securities of the Company issuable or issued upon conversion of the Shares held by and issuable to such Holder (and its affiliates) may be sold pursuant to Rule 144 during any 90 day period. Upon
such termination, such shares shall cease to be “Registrable Securities” hereunder for all purposes. 

  
 10.

 SECTION 3. RIGHTS OF FIRST REFUSAL. 

3.1 Subsequent Offerings. Subject to applicable securities laws, each Investor shall have a right of first refusal to purchase its
pro rata share of all Equity Securities, as defined below, that the Company may, from time to time, propose to sell and issue after the date of this Agreement, other than the Equity Securities excluded by Section 3.6
hereof. Each Investor’s pro rata share is equal to the ratio of (a) the number of shares of the Company’s Common Stock (including all shares of Common Stock issuable or issued upon conversion of the Shares or upon
the exercise of outstanding warrants or options) of which such Investor is deemed to be a holder immediately prior to the issuance of such Equity Securities to (b) the total number of shares of the Company’s outstanding Common Stock
(including all shares of Common Stock issued or issuable upon conversion of the Shares or upon the exercise of any outstanding warrants or options) immediately prior to the issuance of the Equity Securities. The term “Equity
Securities” shall mean (i) any Common Stock, Preferred Stock or other security of the Company, (ii) any security convertible into or exercisable or exchangeable for, with or without consideration, any Common Stock,
Preferred Stock or other security (including any option to purchase such a convertible security), (iii) any security carrying any warrant or right to subscribe to or purchase any Common Stock, Preferred Stock or other security or (iv) any
such warrant or right. 
 3.2 Exercise of Rights. If the Company proposes to issue any Equity Securities, it shall
give each Investor written notice of its intention, describing the Equity Securities, the price and the terms and conditions upon which the Company proposes to issue the same. Each Investor shall have 15 days from the giving of such notice to agree
to purchase its pro rata share of the Equity Securities for the price and upon the terms and conditions specified in the notice by giving written notice to the Company and stating therein the quantity of Equity Securities to be
purchased. Notwithstanding the foregoing, the Company shall not be required to offer or sell such Equity Securities to any Investor who would cause the Company to be in violation of applicable federal securities laws by virtue of such offer or
sale. 
 3.3 Issuance of Equity Securities to Other Persons. If not all of the Investors elect to purchase their
pro rata share of the Equity Securities, then the Company shall promptly notify in writing the Investors who do so elect and shall offer such Investors the right to acquire such unsubscribed shares on a pro
rata basis. The Investors shall have five days after receipt of such notice to notify the Company of its election to purchase all or a portion thereof of the unsubscribed shares. The Company shall have 90 days thereafter to sell the
Equity Securities in respect of which the Investor’s rights were not exercised, at a price and upon general terms and conditions not materially more favorable to the purchasers thereof than specified in the Company’s notice to the
Investors pursuant to Section 3.2 hereof. If the Company has not sold such Equity Securities within 90 days of the notice provided pursuant to Section 3.2, the Company shall not thereafter issue or sell any Equity Securities, without first
offering such securities to the Investors in the manner provided above. 
 3.4 Termination and Waiver of Rights of
First Refusal. The rights of first refusal established by this Section 3 shall not apply to, and shall terminate upon the earlier of (i) the effective date of the registration statement pertaining to the Company’s Initial Offering
or (ii) upon an Acquisition or Asset Transfer (each as defined in the Restated Charter). Notwithstanding Section 4.5 hereof, the rights of first refusal established by this Section 3 may be amended, or any provision waived with and
only with the written consent of the Company  

  
 11.

 
and the Investors holding a majority of the Registrable Securities held by all Investors, or as permitted by Section 4.5. 

3.5 Assignment of Rights of First Refusal. The rights of first refusal of each Investor under this Section 3 may be assigned
to the same parties, subject to the same restrictions as any transfer of registration rights pursuant to Section 2.7. 
 3.6 Excluded Securities. The rights of first refusal established by this Section 3 shall have no application to any of the following Equity Securities: 

(a) shares of the Company’s Common Stock issued upon conversion of the Company’s Preferred Stock; 

(b) shares of the Company’s Common Stock (or options, warrants or rights therefor) issued to employees, officers, directors,
banks or corporate partners of, or contractors, consultants, advisers or equipment lessors to, the Company or any subsidiary pursuant to stock purchase or stock option plans, stock bonuses or awards, warrants, contracts or other arrangements that
are approved by the Company’s Board of Directors; 
 (c) shares of the Company’s Common Stock issued pursuant
to any acquisition of another corporation or entity, whether by merger, purchase of assets or otherwise, under any agreement or arrangement approved by the Company’s Board of Directors; 

(d) shares of Common Stock issued pursuant to the exercise of options, warrants or convertible securities outstanding as of the
date hereof; and 
 (e) any Common Stock or Preferred Stock issued to investors pursuant to the first purchase agreement
entered into by the Company following the date hereof in connection with the sale of Equity Securities in a bona fide capital raising transaction. 
 SECTION 4. MISCELLANEOUS. 
 4.1 Governing Law. This Agreement
shall be governed by and construed under the laws of the State of California in all respects as such laws are applied to agreements among California residents entered into and to be performed entirely within California, without reference to
conflicts of laws or principles thereof. The parties agree that any action brought by either party under or in relation to this Agreement, including without limitation to interpret or enforce any provision of this Agreement, shall be brought in, and
each party agrees to and does hereby submit to the jurisdiction and venue of, any state or federal court located in the County of San Diego, California. 
 4.2 Successors and Assigns. Except as otherwise expressly provided herein, the provisions hereof shall inure to the benefit of, and be binding upon, the parties hereto and their respective
successors, assigns, heirs, executors, and administrators and shall inure to the benefit of and be enforceable by each person who shall be a holder of Registrable Securities from time to time; provided, however, that prior to
the receipt by the Company of adequate written notice of the transfer of any Registrable Securities specifying the full name and address of the transferee, the Company may deem and treat the person listed as the holder of such shares in its 

  
 12.

 
records as the absolute owner and holder of such shares for all purposes, including the payment of dividends or any redemption price. 

4.3 Entire Agreement. This Agreement, the Exhibits and Schedules hereto constitute the full and entire understanding and agreement
between the parties with regard to the subjects hereof and supersedes and entirely replaces the Prior Agreement, which is hereby terminated by this Agreement, and no party shall be liable or bound to any other in any manner by any oral or written
representations, warranties, covenants and agreements except as specifically set forth herein and therein. Each party expressly represents and warrants that it is not relying on any oral or written representations, warranties, covenants or
agreements outside of this Agreement. 
 4.4 Severability. In the event one or more of the provisions of this
Agreement should, for any reason, be held to be invalid, illegal or unenforceable in any respect, such invalidity, illegality, or unenforceability shall not affect any other provisions of this Agreement, and this Agreement shall be construed as if
such invalid, illegal or unenforceable provision had never been contained herein. 
 4.5 Amendment and Waiver.

 (a) Except as otherwise expressly provided, this Agreement may be amended or modified, and the obligations of the
Company and the rights of the Holders under this Agreement may be waived, only upon the written consent of the Company and the holders of at least a majority of the then-outstanding Registrable Securities. 

(b) For the purposes of determining the number of Holders or Investors entitled to vote or exercise any rights hereunder, the
Company shall be entitled to rely solely on the list of record holders of its stock as maintained by or on behalf of the Company. 
 4.6 Delays or Omissions. It is agreed that no delay or omission to exercise any right, power, or remedy accruing to any party, upon any breach, default or noncompliance by another party under this
Agreement shall impair any such right, power, or remedy, nor shall it be construed to be a waiver of any such breach, default or noncompliance, or any acquiescence therein, or of any similar breach, default or noncompliance thereafter occurring. It
is further agreed that any waiver, permit, consent, or approval of any kind or character on any party’s part of any breach, default or noncompliance under the Agreement or any waiver on such party’s part of any provisions or conditions of
this Agreement must be in writing and shall be effective only to the extent specifically set forth in such writing. All remedies, either under this Agreement, by law, or otherwise afforded to any party, shall be cumulative and not alternative.

 4.7 Notices. All notices required or permitted hereunder shall be in writing and shall be deemed effectively
given: (a) upon personal delivery to the party to be notified, (b) when sent by confirmed electronic mail or facsimile if sent during normal business hours of the recipient; if not, then on the next business day, (c) five days after
having been sent by registered or certified mail, return receipt requested, postage prepaid, or (d) one day after deposit with a nationally recognized overnight courier, specifying next day delivery, with written verification of receipt. All

4.8 Attorneys’ Fees. In the event that any suit or action is instituted under or in relation to this Agreement, including

entities under common management or control shall be aggregated together for the purpose of determining the availability of any rights under this Agreement. 
 4.12 Pronouns. All pronouns contained herein, and any variations thereof, shall be deemed to refer to the masculine, feminine or neutral, singular or plural, as to the identity of the parties
hereto may require.
