Re: Representation
Agreement

 

Dear Mr.
Joseph White:

 

Thank
you for choosing Cane Clark LLP (the “Firm”). We appreciate your choice of our firm and look forward to representing
Cubed, Inc. (the “Client”).

 

In
order to prevent misunderstandings and maintain our cordial and professional relationship, this Representation Agreement (“Agreement”)
sets forth the terms and conditions of our representation, including our policies with respect to how we bill for the legal services
rendered and costs incurred on your behalf. Services rendered prior to signing this Agreement are also subject to its terms. It
is important for you to review the contents of this Agreement carefully and call me if you have any questions.

 

Scope
of Engagement

 

You
have asked us and we have agreed, subject to our standard conflict of interest check, to represent the Client to perform specific
legal services set forth in the attached Schedule A (collectively “Scope of Engagement”). Our representation is limited
to the matters listed on Schedule A and we specifically disclaim any representation beyond the stated Scope of Engagement. If
you would like us to represent the Client in connection with any additional matters not specifically listed in Schedule A, please
feel free to contact us so that we may discuss your objectives and prepare a supplemental written schedule encompassing such additional
matters.

 

To
assist us in our representation and to enable us to complete the Client’s matters in a timely manner, we require the Client’s
full cooperation with our office in providing us with access to Client personnel, requested documents and information, keeping
us apprised of any changes in facts and circumstances that affect our services, and the payment of our bills in a current and
timely manner.

 

    	 

    	 

    

The
Client has retained the law firm of Cane Clark LLP and not any individual attorney. It is important that you understand that we
have agreed to act as counsel for Cubed, Inc. ONLY and, in the absence of a separate written representation agreement,
not for any of its principals, control persons, affiliates, interest holders or related entities. Please contact me immediately
if this does not comport with your understanding so that we may create separate written representation agreements and any appropriate
written disclosures and waivers.

 

Legal
Fees and Expenses

 

With
respect to our charges for legal services, many factors are taken into account in quoting the legal fees, including the time expended,
nature, and complexity of the work performed, the time required by the client, and the results achieved for the client by the
firm. Once we have had the opportunity to gather additional information from you, we will be able to provide you with an estimate
of the charges for our services. In certain instances, our office will complete initial research in this matter and will draft
a memorandum of our findings. We will generally charge you for this preliminary research and investigation conducted prior to
our first meeting, as well as the time spent during any initial client interview.

 

Client
agrees to compensate us based upon our standard hourly rates for those personnel performing the specific services required for
the Client. Our lawyers’ hourly rates range from $225 to $500 and our paralegals’ hourly rates range from $100 to
$185. We anticipate that Kyleen Cane ($500 per hour) will be primarily responsible for your matter, together with any other lawyers
or paralegals as may be necessary to complete the Scope of Engagement.

 

We
shall record time to a reasonable fraction of an hour invested in providing services to Client, including local travel time, in
quarter-hour increments. The hourly rate of the Firm’s personnel may be modified from time to time, any new rates, after
adopted, would apply to services rendered after the effective date of the new rates.

 

In
the discharge of our responsibility, it may be necessary for us to incur expenses for various items such as filing fees, EDGAR
or XBRL preparation and filing fees, court costs, court reporter fees, long distance telephone calls, postage, photocopying, overnight
or local delivery services, and in some instances, computerized legal research. These items are charged to each individual client
for whose benefit they are incurred. Therefore, in addition to the legal fees described above, you will be responsible for the
current and timely payment of all out of pocket disbursements, costs, and expenses, which will be separately itemized on our statement
to you. These may include travel, filing fees, and other expenses as reasonably required. We may also, in some instances, forward
invoices for such expenses to you directly.

    	1

    	 

    

 

Engagement
Deposit and Trust Account Instruction

 

At
this time, we will not require that you deposit a retainer with our firm as security for the payment of our bills (an “Engagement
Deposit”). However, we have stated that we are willing to accept common stock of the Client at a value of $1.00 per share
for full payment of legal fees owed by the Client (“Shares”), except for any hard cost expenses incurred by us, so
long as the Client agrees to file an S8 registration statement to register these Shares for resale.

 

Further,
we reserve the right to require that you do deposit a retainer with our firm as a condition of our continued representation as
your strategy changes to include the pursuit of more aggressive or time-intensive tactics or should you become delinquent in the
payment of your bills. If required, the Engagement Deposit will be deposited in our Client Trust Account, but will not bear interest
for the Client’s benefit. The Engagement Deposit will not represent either a minimum fee or an estimate of the total fee
that the engagement may entail. The Client hereby authorizes the Firm to withdraw funds from the Engagement Deposit held in our
Client Trust Account to pay for attorney fees and costs incurred by the Firm, with any balance being refunded at the Client’s
discretion after termination of this engagement. The Client authorizes such disbursement prior to any other competing claim against
the Engagement Deposit or against any other Client funds maintained in our Client Trust Account.

 

Terms
of Payment

 

It
is our practice to send a monthly statement for services rendered during the previous month and for disbursements incurred on
Client’s account. The detail in the monthly statement will inform you of both the nature and process of the work and fees
and disbursements incurred. We do our best to ensure that our clients are fully satisfied not only with our services, but also
with the reasonableness of the fees and disbursements charged for those services. Therefore, if you have any question about any
invoice or the basis for our fees to you, you should raise it with us promptly for discussion. If you object only to a portion
of the invoice, we require that you timely pay the remainder, which will not constitute a waiver of your objection.

 

It
is critical that you make us aware of any disputes you may have with any of our charges or invoices immediately as we will rely,
in part, on a Client’s failure to object to our open invoices in determining to continue to provide services to the Client,
particularly where we are not holding an Engagement Deposit that exceeds the sum of our open invoices and the expected work for
the current billing cycle. Therefore, if the Client disputes any invoice, in whole or in part, we must receive written notice
of the objection as soon as practicable, but in no event later than forty-five (45) days from the date of the invoice so that
we may work with you to resolve the dispute in a timely fashion. The Client’s failure to provide us timely written notice
of an objection to our invoices constitutes a waiver of the objection.

 

We
ask and expect payment of our billings and retainers on a monthly basis. Our billing statements are due and payable upon receipt
since there is generally a relatively significant time lag between the rendering of our services and the submission of our statement.
Our firm will assess an interest charge of one and one-half percent (1.5%) per month on the unpaid balances of all billing statements
that are outstanding for more than thirty days. You will be responsible for any costs of collection incurred by our Firm, including
reasonable attorneys’ fees. If a billing becomes delinquent, we reserve the right to suspend legal services until the account
is current and/or an additional retainer is received.

 

Termination

 

This
Agreement may be prospectively terminated at any time upon reasonable advance written notice given by either party. If you change
your mind and no longer want us to complete this engagement, then the Engagement Deposit is refundable to the extent it exceeds
the costs incurred, as herein described, and the fees for the time spent on the project by attorneys and paralegals billed at
their customary hourly rate. We also reserve the right to limit or withdraw from further representation in the event you fail
to render payment when due, or if we determine that our continued representation of you would be unethical or inappropriate, or
if we have another reasonable basis for termination consistent with our professional duties to you as set forth in the Rules of
the Nevada Supreme Court. You will be charged for time, fees and costs incurred in formally withdrawing from any matter, including
any necessary motions or court appearances.

 

Retaining
Lien

 

Nevada
law permits us to hold the Client’s file and property, including the originals of any document or instruments, as security
for the payment of our final bill.

 

Conflict
of Interest

 

We
have performed a conflict of interest check and, with the exception of those matters identified in the Conflict Waiver Rider attached
hereto as Schedule B, have determined that we do not have a conflict with representing you in this matter. However, should you
believe that there are or will be other parties with a direct economic or personal interest relating to our representation, which
have not been previously disclosed to us, you agree to immediately contact us in writing with such information. We may not represent
multiple clients who have directly adverse interests without first explaining the facts and circumstances that give rise or may
give rise to the conflict and obtaining their informed written consent.

 

    	2

    	 

    

 

Electronic
Communications

 

It
is the policy of the Firm to utilize the most efficient method of communicating with our clients. Accordingly, unless you specifically
direct us to the contrary, where feasible we will attempt to correspond with you via electronic mail.

 

Record
Retention Policy

 

All
records and files will be retained and disposed of in compliance with our policy in effect from time to time. Subject to future
changes, it is our policy not to retain records relating to a matter for more than five (5) years from the date the matter is
opened. Upon your prior written request, we will return records to you prior to their destruction. It is not administratively
feasible for us to advise you of the closing of a matter or the disposal of records. We recommend, therefore, that you maintain
your own files for reference to make written request for your files at the conclusion of a matter. If you have any questions concerning
our records retention policies, please contact us.

 

Results

 

Nothing
in this Agreement, or any of our statements to you should be construed as a promise or guarantee about the outcome of any matter
being handled. You understand that we have not and cannot guarantee results, and that our services shall be to give Client legal
advice and advocate Client’s position with regard to the matters described within Schedule A. Any comments about outcomes
are expressions of opinion only.

 

No
Continuing Obligation

 

Once
the legal work is complete, we have no obligation to inform you of future developments relative to legal work performed hereunder.
We advise that you periodically consult with an attorney with regard to any such future developments or if there is a significant
change in your circumstances.

 

Severability

 

Every
provision of this Agreement is severable. If any provision hereof is held to be illegal or invalid for any reason whatsoever,
such illegality or invalidity shall not affect the validity of the remainder of this Agreement.

 

Arbitration

 

Client
hereby agrees that, at the option of the Firm, any controversy between the Firm and the Client (including, without limitation,
any controversy regarding the construction of the Agreement, and any claim arising out of this Agreement or its breach), shall
be submitted to binding arbitration upon the written request of the Firm. The parties to such arbitration shall comply with the
rules of the American Arbitration Association. The prevailing party in any such arbitration shall be entitled to a reasonable
award of attorneys’ fees and costs, including the cost of the arbitration.

    	3

    	 

    

 

Malpractice
Claim Subject to Arbitration

 

If
Client claims that the Firm committed malpractice or otherwise performed any legal services improperly, negligently, or incompetently,
then Client hereby agrees to submit the dispute to binding arbitration. By agreeing to this provision, Client understands that
Client waives the right to bring an action against the Firm in a court a law and further waives the right to a jury trial. The
cost of any such arbitration shall be borne by the losing party or in such proportion as the arbitrators shall decide. The parties
to such arbitration shall comply with the rules of the American Arbitration Association. The prevailing party in any such arbitration
shall be entitled to a reasonable award of attorneys’ fees and costs, including the cost of the arbitration.

 

Applicable
Law and Venue

 

The
laws of the State of Nevada shall govern the interpretation of this Agreement, exclusive of any choice of law provision. Client
consents to the jurisdiction of the state of Nevada for all disputes between Client and the Firm and agrees that exclusive venue
for the resolution of any such disputes shall be Clark County, Nevada.

 

Integrated
Agreement

 

This
Agreement and the documents executed or delivered in connection therewith constitute the entire understanding and agreement between
the parties hereto with respect to the subject matter hereof. There are no agreements, understandings, restrictions, representations,
or warranties other than those set forth or referred to herein.

 

Modification

 

This
Agreement reflects the standard terms upon which we currently make our services available to clients. In the event that such standard
terms are modified in the future, this Agreement may be amended by us to reflect such modified standard terms (an “Amended
Agreement”). Unless you provide us with a written request, no separate modification of this Agreement is necessary to effect
such change, including with respect to the hourly rates of any particular individual. If the Client agrees and desires to receive
services from us under the Amended Agreement, no further action evidencing agreement need be taken by the Client.

 

On
the other hand, if the Client does not agree or desire to receive services from the Firm pursuant to the terms of the Amended
Agreement, Client may at any time, within (15) days of transmittal of the intent to amend this Agreement, exercise its existing
right to unilaterally terminate this Agreement by written notice to the Firm pursuant to the termination clause of this Agreement,
and the Firm shall thereupon discharge its termination responsibilities hereunder.

The
undersigned warrants and represents that he or she has full power and authority to enter into this Agreement on behalf of the
Client.

 

If
you understand these billing and policy arrangements and find them acceptable, please sign the Acknowledgment and return it to
me. Please retain a copy for your records.

 

Again,
we thank you for choosing our firm and assure you of our best professional efforts. Should you have any questions, please contact
me.

date of an IPO that the Company file a registration statement under the Securities Act (provided that the anticipated aggregate offering price would exceed $5,000,000), then the Company shall: 

(i) within ten (10) days of the receipt thereof, give written notice of such request to all Holders; and 

(ii) use its reasonable best efforts to effect, as soon as practicable after receipt of such request, the registration under the
Securities Act of that number of Registrable Securities which the Holders (including the Initiating Holders) requested to be registered, subject to the limitations of Section 1.2(b), within twenty (20) days of the mailing of such notice by
the Company. 
 (b) If the Holders initiating the registration request hereunder (the “Initiating Holders”)
intend to distribute the Registrable Securities covered by their request by means of an underwriting, they shall so advise the Company as a part of their request made pursuant to Section 1.2(a) and the Company shall include such information in
the written notice referred to in Section 1.2(a). In such event, the right of any Holder to include its Registrable Securities in such registration shall be conditioned upon such Holder’s participation in such underwriting and the
inclusion of such Holder’s Registrable Securities in the underwriting (unless otherwise mutually agreed by a majority in interest of the Initiating Holders and such Holder) to the extent provided herein. All Holders proposing to distribute
their securities through such underwriting shall (together with the Company as provided in Section 1.5(f)) enter into an underwriting agreement in customary form with the underwriter or underwriters selected for such underwriting;
provided, however, that no Holder (or any of their assignees) shall be required to make any representations, warranties or indemnities except as they relate to such Holder’s ownership of shares and authority to enter into the
underwriting agreement and to such Holder’s intended method of distribution, and the liability of such Holder shall be limited to an amount equal to the net proceeds from the offering received by such Holder. Notwithstanding any other provision
of this Section 1.2, if the underwriter advises the Initiating Holders in writing that marketing factors require a limitation of the number of shares to be underwritten, then the Initiating Holders shall so advise all Holders of Registrable
Securities which would otherwise be underwritten pursuant hereto, and the number of shares of Registrable Securities that may be included in the underwriting shall be allocated among all Holders thereof, including the Initiating Holders, in
proportion (as nearly as practicable) to the amount of Registrable Securities of the Company owned by each Holder; provided, however, that the number of shares of Registrable Securities to be included in such underwriting shall not be
reduced unless all other securities are first entirely excluded from the underwriting. 

 (c) The Company shall not be obligated to effect, or to take any action to effect, any
registration pursuant to this Section 1.2: 
 (i) After the Company has effected two (2) registrations pursuant to this
Section 1.2 in which all securities to be included were in fact included and such registrations have been declared or ordered effective with respect to all Registrable Securities requested to be registered; provided, however, that any
registration that is withdrawn or closed at the request of the Initiating Holders (other than as a result of a material adverse change affecting the Company) shall count as one (1) of the two (2) required registrations pursuant to this
Section 1.2(c)(i); or 
 (ii) If the Company delivers notice to the Initiating Holders within thirty (30) days of such
Initiating Holders’ registration request that the Company intends to file the first registration statement for a public offering of securities of the Company on its behalf (other than a registration statement relating either to the sale of
securities to employees of the Company pursuant to a stock option, stock purchase or similar plan or a transaction pursuant to Rule 145 of the Securities Act (“SEC Rule 145”)) within sixty (60) days from the date of such
notice; provided, that the Company is actively employing in good faith commercially reasonable efforts to cause such registration statement to be filed and declared effective. 

1.3 Company Registration. 

(a) If (but without any obligation to do so) the Company proposes to register (including for this purpose a registration effected by
the Company for stockholders other than the Holders) any of its stock or other securities under the Securities Act in connection with the public offering of such securities solely for cash (other than a registration statement relating either to the
sale of securities to employees of the Company pursuant to a stock option, stock purchase or similar plan or an SEC Rule 145 transaction), the Company shall, at such time, promptly give each Holder written notice of such registration. Upon the
written request of each Holder given within twenty (20) days after mailing of such notice by the Company, the Company shall cause to be registered under the Securities Act all of the Registrable Securities that each such Holder has requested to
be registered. 
 (b) If the registration statement under which the Company gives notice under this Section 1.3 is for an
underwritten offering, the Company shall so advise the Holders of Registrable Securities. In such event, the right of any such Holder to be included in a registration pursuant to this Section 1.3 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; provided, however, that no Holder (or any of their assignees) shall be required to make any
representations, warranties or indemnities except as they relate to such Holder’s ownership of shares and authority to enter into the underwriting agreement and to such Holder’s intended method of distribution, and the liability of such
Holder shall be limited to an amount equal to the net proceeds from the offering received by such Holder. Notwithstanding any other provision of the 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: (i) first, to the Company; (ii) second, to the Holders on a pro rata basis based on the total number of
Registrable Securities held by the Holders; and (iii) third, to any stockholder of the Company (other than a Holder) on a pro rata basis. No such reduction shall reduce the amount of securities of the selling Holders included in the
registration below thirty percent (30%) of the total amount of securities included in such registration, unless such offering is the Company’s initial public offering of shares of Common Stock registered under the Securities Act and such
registration does not include shares of any other selling stockholders, in which event any or all of the Registrable Securities of the 

 
Holders may be excluded in accordance with the immediately preceding sentence at the underwriter’s discretion. In no event will shares of any other selling stockholder be included in such
registration which 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 ten (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, managers,
members and stockholders of such Holder, or the estates and family members of any such partners, members and retired partners and any trusts for the benefit of any of the foregoing persons 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.

 1.4 Form S-3 Registration. In the event that the Company receives a written request from the Holders of at least ten percent
(10%) of the Registrable Securities that the Company effect a registration on Form S-3 and any related qualification or compliance with respect to all or a part of the Registrable Securities owned by such Holders, the Company will: 

(a) give written notice of the proposed registration, and any related qualification or compliance, to all other Holders within ten
(10) days after the date such request is given; and 
 (b) as soon as practicable, effect such registration and all such
qualifications and compliances as may be so requested and as would permit or facilitate the sale and distribution of all or such portion of such Holder’s or Holders’ Registrable Securities as are specified in such request, together with
all or such portion of the Registrable Securities of any other Holder or Holders joining in such request as are specified in a written request given within fifteen (15) days after receipt of such written notice from the Company;
provided, however, that the Company shall not be obligated to effect any such registration, qualification or compliance, pursuant to this Section 1.4: (i) if Form S-3 is not available for such offering by the Holders;
(ii) if the Holders, together with the holders of any other securities of the Company entitled to inclusion in such registration, propose to sell Registrable Securities and such other securities (if any) at an aggregate price to the public of
less than $1,000,000; (iii) if the Company has, within the 12-month period preceding the date of such request, already effected two (2) registrations on Form S-3 for the Holders pursuant to this Section 1.4; or (iv) in any
particular jurisdiction in which the Company would be required to qualify to do business or to execute a general consent to service of process in effecting such registration, qualification or compliance. 

(c) Subject to the foregoing, the Company shall file a Form S-3 registration statement covering the Registrable Securities and other
securities so requested to be registered as soon as practicable after receipt of the request or requests of the Holders. Registrations effected pursuant to this Section 1.4 shall not be counted as demands for registration or registrations
effected pursuant to Sections 1.2 or 1.3, respectively. 
 1.5 Obligations of the Company. Whenever required under this
Section 1 to effect the registration of any Registrable Securities, the Company shall, as expeditiously as reasonably possible: 

(a) prepare and file with the SEC a registration statement with respect to such Registrable Securities, use its reasonable best efforts
to cause such registration statement to become effective, and, upon the request of the Holders of a majority of the Registrable Securities registered thereunder, keep such registration statement effective for a period of up to one (1) year or
until the distribution contemplated in 

 
the registration statement has been completed; provided, however, that (i) such one (1) year period shall be extended for a period of time equal to the period any Holder
refrains from selling any securities included in such registration at the request of the Company or any underwriter for the Company; and (ii) in the case of any registration of Registrable Securities on Form S-3 which are intended to be offered
on a continuous or delayed basis, such one (1) year period shall be extended, if necessary, to keep the registration statement effective until all such Registrable Securities are sold; 

(b) prepare and file with the SEC such amendments and supplements to such 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; 

(c) furnish to the Holders such numbers 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; 

(d) use its reasonable best 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, however, 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, unless the Company is already subject to service in such jurisdiction and except as may be required by the Securities Act; 

(e) in the event of any order suspending the effectiveness of a registration statement, use its reasonable best efforts to obtain the
withdrawal of such order at the earliest possible time; 
 (f) 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 of such offering; 

(g) notify each Holder of Registrable Securities covered by a 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; 

(h) notify each Holder of Registrable Securities covered by a registration statement of: (i) the effectiveness of such
registration statement; (ii) the filing of any post-effective amendments to such registration statement; or (iii) the filing of a supplement to such registration statement; 

(i) make available for inspection, upon reasonable notice during the Company’s regular business hours, by each Holder of
Registrable Securities covered by a registration statement, any underwriter participating in any distribution pursuant to such registration statement, and any attorney, accountant or other agent retained by such Holder or underwriter, all material
financial and other records, pertinent corporate documents and properties of the Company, and cause the Company’s officers, directors and employees to supply all information reasonably requested by any such Holder, underwriter, attorney,
accountant or agent in connection with such registration statement; 

 (j) upon the transfer of shares by a Holder in connection with a registration hereunder,
furnish unlegended certificates representing ownership of the Registrable Securities being sought in such denominations as shall be requested by the Holders or the underwriters; 

(k) cause all such Registrable Securities registered pursuant hereunder to be listed on each securities exchange on which similar
securities issued by the Company are then listed; 
 (l) provide a transfer agent and registrar for all Registrable Securities
registered pursuant hereunder and a CUSIP number for all such Registrable Securities, in each case not later than the effective date of such registration; and 

(m) furnish, at the request of any Holder, on the date that such Holder’s Registrable Securities are delivered to the underwriters
for sale in connection with a registration pursuant to this Agreement, if such securities are being sold through underwriters, or, if such securities are not being sold through underwriters, on the date that the registration statement with respect
to such securities becomes effective: (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 and reasonably satisfactory to a majority in interest of the Holders requesting registration, addressed to the underwriters and to the Holders requesting registration of Registrable Securities; and (ii) a “comfort” 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 and reasonably
satisfactory to a majority in interest of the Holders requesting registration, addressed to the underwriters and to the Holders requesting registration of Registrable Securities. 

1.6 Furnish Information. 

(a) It shall be a condition precedent to the obligations of the Company to take any action pursuant to this Section 1 with respect
to the Registrable Securities of any selling Holder that such Holder shall furnish to the Company such information regarding itself, the Registrable Securities held by it, and the intended method of disposition of such securities as shall be
required to effect the registration of such Holder’s Registrable Securities. 
 (b) The Company shall have no obligation with
respect to any registration requested pursuant to Section 1.2 if, due to the operation of Section 1.6(a), the number of shares or the anticipated aggregate offering price of the Registrable Securities to be included in the registration
does not equal or exceed the number of shares or the anticipated aggregate offering price required to originally trigger the Company’s obligation to initiate such registration as specified in Section 1.2(a). 

1.7 Expenses of Registration. Except as specifically provided herein, all Registration Expenses incurred in connection with any
registration, qualification or compliance pursuant to Section 1.2, Section 1.3 or Section 1.4 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. 
 1.8 Indemnification.
In the event any Registrable Securities are included in a registration statement under this Section 1: 
 (a) To the extent
permitted by law, the Company will indemnify and hold harmless each selling Holder, and the partners, members, officers, directors, and stockholders of each such Holder; legal counsel, investment advisors and accountants for each such Holder; and
any underwriter for each 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”): (i) any untrue statement or alleged untrue statement of a material fact contained in such registration statement, 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; and the Company will pay to each such Holder, underwriter, controlling person or other aforementioned person 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 1.8(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 solely in reliance upon and in conformity with written information furnished expressly for use in connection with such registration by any such Holder, underwriter, controlling person or other aforementioned person.

 (b) To the extent permitted by law, each selling Holder will, severally but not jointly, indemnify and hold harmless the Company,
each of its directors, each of its officers who has signed the registration statement, each person, if any, who controls the Company within the meaning of the Securities Act, any underwriter (as defined in the Securities Act), any other Holder
selling securities in such registration statement and any controlling person of any such underwriter or other Holder, against any losses, claims, damages, or liabilities (joint or several) to which any of the foregoing persons 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 Violation, in each case to the extent (and only to
the extent) that such Violation occurs solely in reliance upon and in conformity with written information furnished by such selling Holder expressly for use in connection with such registration; and each such selling Holder will pay any legal or
other expenses reasonably incurred by any person intended to be indemnified pursuant to this Section 1.8(b), in connection with investigating or defending any such loss, claim, damage, liability, or action; provided, however, that
the indemnity agreement contained in this Section 1.8(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; and provided further that, in no event shall the aggregate amounts payable by any Holder by way of indemnity or contribution under this Section 1.8 exceed the net proceeds from the offering received by such
Holder. 
 (c) Promptly after receipt by an indemnified party under this Section 1.8 of notice of the commencement of any action
(including any governmental action) for which a party may be entitled to indemnification hereunder, such indemnified party will, if a claim in respect thereof is to be made against any indemnifying party under this Section 1.8, deliver to the
indemnifying party a notice of the commencement thereof. The indemnifying party shall have the right to participate in such action, and, to the extent the indemnifying party so desires, participate jointly with any other indemnifying party similarly
noticed, and to assume the defense thereof with counsel mutually satisfactory to the parties; provided, however, that an indemnified party (together with all other indemnified parties which may be represented without conflict by one
counsel) shall have the right to retain one separate counsel, with the fees and expenses 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, if
prejudicial to its ability to defend such action, shall relieve such indemnifying party of any liability to the indemnified party under this Section 1.8, but the failure to deliver 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 1.8. 
 (d) If the indemnification
provided for in this Section 1.8 is held by a court of competent jurisdiction to be unavailable to an indemnified party with respect to any loss, liability, claim, damage, or expense referred to therein, then the indemnifying party, in lieu of
indemnifying such indemnified party hereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such loss, liability, claim, damage, or expense 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 statements or omissions that resulted in such loss, liability, claim, damage, or expense as well as any other relevant equitable
considerations. The relative fault of the indemnifying party and of the indemnified party shall be determined 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 or prevent such statement or omission. 

(e) Notwithstanding the foregoing, to the extent that the provisions relating to indemnification and contribution contained in the
underwriting agreement entered into in connection with the underwritten public offering are in conflict with the foregoing provisions, the provisions in the underwriting agreement shall control; provided, however, that the failure of the
underwriting agreement to provide for or address a matter that is specifically provided for or addressed by the foregoing provisions of this Section 1.8 shall not be a conflict between the underwriting agreement and the foregoing provisions
and, in such event, the foregoing provisions shall control. 
 (f) Unless otherwise superseded by an underwriting agreement entered
into in connection with the firm commitment underwritten public offering, the obligations of the Company and Holders under this Section 1.8 shall survive the completion of any offering of Registrable Securities in a registration statement under
this Section 1, and otherwise shall survive the termination of this Agreement. 
 1.9 Reports Under the Exchange Act. With a
view to making available to the Holders the benefits of Rule 144 promulgated under the Securities Act (“SEC Rule 144”) and any other rule or regulation of the SEC that may at any time permit a Holder to sell securities of the
Company to the public without registration or pursuant to a registration on Form S-3, the Company agrees to: 
 (a) make and keep
public information available, as those terms are understood and defined in SEC Rule 144, at all times after ninety (90) days after the effective date of the first registration statement filed by the Company for the offering of its securities to
the general public (other than a registration statement relating either to the sale of securities to employees of the Company pursuant to a stock option, stock purchase or similar plan or an SEC Rule 145 transaction); 

(b) take such action, including the voluntary registration of its Common Stock under Section 12 of the Exchange Act, as is
necessary to enable the Holders to utilize Form S-3 for the sale of their Registrable Securities, such action to be taken as soon as practicable after the end of the fiscal year in which the first registration statement filed by the Company for the
offering of its securities to the general public (other than a registration statement relating either to the sale of securities to employees of the Company pursuant to a stock option, stock purchase or similar plan or an SEC Rule 145 transaction) is
declared effective; 

 (c) file with the SEC in a timely manner all reports and other documents required of the
Company under the Securities Act and the Exchange Act; and 
 (d) furnish to any Holder, so long as the Holder owns any Registrable
Securities, forthwith upon request: (i) a written statement by the Company that it has complied with the reporting requirements of SEC Rule 144 (at any time after ninety (90) days after the effective date of the first registration
statement filed by the Company), the Securities Act and the Exchange Act (at any time after it has become subject to such reporting requirements), or that it qualifies as a registrant whose securities may be resold pursuant to Farm S-3 (at any time
after it so qualifies); (ii) a copy of the most recent annual or quarterly report of the Company and such other reports and documents so filed by the Company; and (iii) such other information as may be reasonably requested in availing any
Holder of any rule or regulation of the SEC which permits the selling of any such securities without registration or pursuant to such form. 

1.10 Limitation on Subsequent Registration Rights. After the date of this Agreement, the Company shall not, without the prior written
consent of the Requisite Holders, enter into any agreement with any holder or prospective holder of any securities of the Company that would grant such holder registration rights pari passu with or senior to those granted to the Holders
hereunder. 
 1.11 Assignment of Registration Rights. The rights of a Holder pursuant to this Section 1 may be assigned (but
only with all related obligations) by a Holder to one or more transferees or assignees of such securities (an “Assignee”): (i) to whom such Holder transfers such securities pursuant to Section 3.2 hereof;
(ii) who is an employee, affiliate or affiliated partnership managed by such Holder; or (iii) who, after such assignment or transfer, acquires at least ten percent (10%) (subject to appropriate adjustment for stock splits, stock
dividends, combinations and other recapitalizations) of the Registrable Securities held by the Holder as of the date of this Agreement, provided that: (a) the Company is, within a reasonable time after such transfer, furnished with written
notice of the name and address of such Assignee and the securities with respect to which such registration rights are being assigned; and (b) such Assignee agrees in writing to be bound by and subject to the terms and conditions of this
Agreement. 
 1.12 Termination of Registration Rights. No Holder shall be entitled to exercise any right provided for in this
Section 1 after five (5) years following the consummation of the sale of securities pursuant to a Qualifying IPO or, as to any Holder, such earlier time at which all Registrable Securities held by such Holder (and any affiliate of the
Holder with whom such Holder must aggregate its sales under SEC Rule 144) can be sold without restriction in any three (3) month period without registration in compliance with SEC Rule 144. 

2. ADDITIONAL COVENANTS. 
 2.1 Delivery
of Financial Statements. The Company shall deliver to each Investor (who is not a competitor of the Company): 
 (i) as soon as
practicable, but in any event within one hundred twenty (120) days after the end of each fiscal year of the Company, an income statement and statement of cash flows for such fiscal year, a balance sheet of the Company and statement of
stockholder’s equity as of the end of such year, and a schedule as to the sources and applications of funds for such year, such year-end financial reports to be in reasonable detail, prepared in accordance with generally accepted accounting
principles, and audited and certified by nationally recognized independent public accountants selected by the Company and approved by the Board of Directors; 

 (ii) as soon as practicable, but in any event within forty-five (45) days after the
end of each of the first three (3) quarters of each fiscal year of the Company, an unaudited income statement and statement of cash flows for the relevant fiscal quarter, schedule as to the sources and application of funds for such fiscal
quarter, and an unaudited balance sheet as of the end of such fiscal quarter, all prepared in accordance with generally accepted accounting principles, except for any otherwise applicable footnote disclosures; 

(iii) as soon as practicable, but in any event within thirty (30) days of the end of each month, an unaudited income statement,
statement of cash flows, schedule as to the sources and application of funds and balance sheet for and as of the end of such month, in reasonable detail, prepared in accordance with generally accepted accounting principles, except for any otherwise
applicable footnote disclosures; 
 (iv) as soon as practicable, but in any event at least thirty (30) days prior to the end of
each fiscal year, a comprehensive operating budget for the upcoming fiscal year forecasting the Company’s revenues, expenses and cash position on a month-to-month basis for the upcoming fiscal year; and 

(v) such other information relating to the financial condition, business, prospects, or corporate affairs of the Company as such
Investor may from time to time reasonably request; provided, however, that the Company shall not be obligated under this Section 2.1 to provide information (i) that the Company reasonably determines in good faith to be
a trade secret or confidential information (unless covered by an enforceable confidentiality agreement, in a form acceptable to the Company); or (ii) the disclosure of which would adversely affect the attorney-client privilege between the
Company and its counsel. 
 2.2 Right of First Refusal. Subject to the terms and conditions specified in this Section 2.2, the
Company hereby grants to each Investor a right of first refusal with respect to future sales by the Company of Additional Shares of Common Stock (as defined in the Restated Certificate). For purposes of this Section 2.2, the term
“Investor” shall include any general partners and affiliates of a Investor, and each Investor shall be entitled to apportion the right of first refusal hereby granted to it among itself and its partners and affiliates in such proportions
as it deems appropriate. 
 (a) Subject to Section 2.2(e), each time the Company proposes to offer any Additional Shares of
Common Stock, the Company shall first make an offering of such Additional Shares of Common Stock to each Investor in accordance with the following provisions: 

(b) The Company shall deliver a notice by certified mail (the “Notice”) to each Investor stating: (i) its
bona fide intention to offer such Additional Shares of Common Stock; (ii) the number of such Additional Shares of Common Stock to be offered; and (iii) the price and terms, if any, upon which it proposes to offer such Additional Shares of
Common Stock. 
 (c) Within thirty (30) calendar days after receipt of the Notice, each Investor may elect to purchase or
obtain, at the price and on the terms specified in the Notice, up to that portion of such Additional Shares of Common Stock which equals the proportion that the number of shares of Series B Preferred Stock, Series C Preferred Stock and Series D
Preferred Stock then held by such Investor (calculated on an as-converted basis) bears to the total number of shares of Series B Preferred Stock, Series C Preferred Stock and Series D Preferred Stock then outstanding (calculated on an as-converted
basis). The Company shall promptly, in writing, inform each Investor that elects to purchase all of the Additional Shares of Common Stock available to it (each, a “Participating Investor”) of any other Investor’s failure
to do likewise. During the ten (10) day period commencing after receipt of such notice, each Participating Investor shall be entitled 

 
to obtain that portion of the Additional Shares of Common Stock for which Investors were entitled to, but did not, subscribe equal to the proportion that the number of shares of Series B
Preferred Stock, Series C Preferred Stock and Series D Preferred Stock then held by such Participating Investor (calculated on an as-converted basis) bears to the total number of shares of Series B Preferred Stock, Series C Preferred Stock and
Series D Preferred Stock then held by all Participating Investors (calculated on an as-converted basis) who wish to purchase some of the unsubscribed Additional Shares of Common Stock. 

(d) If all Additional Shares of Common Stock that Investors are entitled to obtain pursuant to Section 2.2(b) are not subscribed
for as provided in Section 2.2(c), the Company may, during the sixty (60) day period following the expiration of the period provided in Section 2.2(c), offer the remaining unsubscribed portion of such Additional Shares of Common Stock
to any person or persons at a price not less than that, and upon terms no more favorable to such person or persons than those, specified in the Notice. If the Company does not enter into an agreement for the sale of the Additional Shares of Common
Stock within such period, or if such agreement is not consummated within thirty (30) days of the execution thereof, the right provided hereunder shall be deemed to be revived and such Additional Shares of Common Stock shall not be offered
unless first reoffered to the Investors in accordance herewith. 
 (e) The rights of first refusal of each Investor under this
Section 2.2 may be transferred to the same parties, subject to the same restrictions, as any transfer of registration rights pursuant to Section 1.11. 

2.3 Inspection Rights. Subject to the execution of reasonable nondisclosure agreements (if appropriate), each Investor shall have the
right to visit and inspect any of the properties of the Company, to discuss the affairs, finances and accounts of the Company with its officers, and to review such information as is reasonably requested all at such reasonable times (during normal
business hours) and as often as may be reasonably requested for any purpose reasonably related to such Investor’s interest as a stockholder of the Company; provided, however, that the Company shall not be obligated under this
Section 2.3 with respect to a competitor of the Company or with respect to information which the Board of Directors determines in good faith is confidential or attorney-client privileged and should not, therefore, be disclosed. 

2.4 D&O Insurance Coverage. The Company agrees to: (i) maintain a D&O insurance policy covering members of the Board of
Directors (and their affiliated funds) and officers of the Company in an amount reasonably satisfactory to the Board of Directors; (ii) provide all members of the Board of Directors with indemnification to the fullest extent possible under
Delaware law; (iii) enter into the Company’s standard form of indemnity agreement with each member of the Board of Directors; and (iv) ensure that any successor of the Company assumes the Company’s obligations with respect to
indemnification of the members of the Board of Directors. 
 2.5 Observation Rights. Subject to the approval of the Board of
Directors, each of the Novo Major Investor, RiverVest Major Investor, TPG Major Investor, Domain Major Investor, Avalon Major Investor, OrbiMed Major Investor and Aperture Venture Partners shall have the right to designate one (1) individual
(collectively, the “Board Observers”) who shall be entitled to notice of, to attend, and participate in, as a nonvoting observer, and to any documentation distributed to members before, during and after, all meetings of the
Board of Directors, including executive sessions of the Board of Directors. The Company reserves the right to exclude such observer from any meeting or portion thereof of the Board of Directors, and to withhold access to any material or portion
thereof provided to the directors, if the Board of Directors believes, in good faith, in reliance upon the advice of counsel, and after discussing with such observer, that: (i) access to such information or attendance at such meeting could
adversely affect the attorney-client privilege between the Company and its counsel; or (ii) access to such information or attendance at such meeting could result in a conflict of interest between the Novo Major Investor, RiverVest Major
Investor, 

 
TPG Major Investor, Domain Major Investor, Avalon Major Investor, OrbiMed Major Investor or Aperture Venture Partners, as applicable, and the Company. Each of the Novo Major Investor, RiverVest
Major Investor, TPG Major Investor, Domain Major Investor, Avalon Major Investor, OrbiMed Major Investor and Aperture Venture Partners agrees, and any representative of the Novo Major Investor, RiverVest Major Investor, TPG Major Investor, Domain
Major Investor, Avalon Major Investor, OrbiMed Major Investor and Aperture Venture Partners agrees, to not disclose any confidential information provided to or learned by it in connection with its rights under this Section 2.5. In the event
that Aperture Venture Partners ceases to hold shares of Series C Preferred Stock, it shall not be entitled to the rights under this Section 2.5. 

2.6 Board of Directors Matters. 

(a) Unless otherwise agreed by a majority of the members of the Board of Directors, meetings of the Board of Directors shall be held at
least quarterly. The Company shall reimburse all members of the Board of Directors (but not the Board Observers) for all reasonable expenses incurred by them in connection with the attendance of meetings of the Board of Directors. 

(b) Each committee of the Board of Directors shall include at least two Series B Directors and the OrbiMed Director. 

(c) The Company agrees that it shall not, without approval of the Board of Directors, which approval must include the affirmative vote
of the Preferred Director Majority: (i) make any loan or advance to, or own any stock or other securities of, any subsidiary or other corporation, partnership or other entity unless it is wholly owned by the Company; (ii) make any loan or
advance to any person, including, any employee or director, except advances and similar expenditures in the ordinary course of business or under the terms of an employee stock or option plan approved by the Board of Directors; (iii) guarantee
any indebtedness except for trade accounts of the Company or any subsidiary arising in the ordinary course of business; (iv) make any investment other than investments in prime commercial paper, money market funds, certificates of deposit in
any United States bank having a net worth in excess of $100,000,000 or obligations issued or guaranteed by the United States, in each case having a maturity not in excess of two years; (v) incur any aggregate indebtedness in excess of $100,000
that is not already included in a Board of Directors-approved budget, other than trade credit incurred in the ordinary course of business; (vi) enter into or be a party to any transaction with any director, officer or employee of the Company or
any “associate” (as defined in Rule 12b-2 promulgated under the Exchange Act) of any such person except transactions made in the ordinary course of business and pursuant to reasonable requirements of the Company’s business and upon
fair and reasonable terms that are approved by a majority of the members of the Board of Directors; (vii) hire, fire or change the compensation of the Chief Executive Officer of the Company or other executive officers, including approving any
option plans for the Chief Executive Officer of the Company or other executive officers; (viii) change the principal business of the Company, enter new lines of business or exit the current line of business; (ix) sell, assign, transfer,
license, pledge or encumber technology or intellectual property, other than licenses granted in the ordinary course of business; (x) enter into any corporate strategic relationship involving the payment, contribution or assignment by the
Company or to the Company of assets greater than $100,000 or (xi) incur indebtedness pursuant to the Loan and Security Agreement with Square 1 Bank, dated July 31, 2013, as may be amended from time to time. 

2.7 Proprietary Rights Assignment Agreements. The Company will cause each person now or hereafter employed by it or by any subsidiary
(or engaged by the Company or any subsidiary as a consultant/independent contractor) to enter into a nondisclosure and proprietary rights assignment agreement, substantially in the form approved by the Board of Directors. 

 2.8 Successor Indemnification. If the Company or any of its successors or assignees
consolidates with or merges into any other entity and is not the continuing or surviving corporation or entity of such consolidation or merger, then to the extent necessary, proper provision shall be made so that the successors and assignees of the
Company assume the obligations of the Company with respect to indemnification of members of the Board of Directors as in effect immediately before such transaction, whether such obligations are contained in the Company’s Bylaws, its Certificate
of Incorporation, as amended, or elsewhere, as the case may be. 
 2.9 Indemnification Matters. The Company hereby acknowledges that
one (1) or more of the directors nominated to serve on the Board of Directors by the Investors (each a “Fund Director”) may have certain rights to indemnification, advancement of expenses and/or insurance provided by one or
more of the Investors and certain of their affiliates (collectively, the “Fund Indemnitors”). The Company hereby agrees (a) that it is the indemnitor of first resort (i.e., its obligations to any such Fund Director
are primary and any obligation of the Fund Indemnitors to advance expenses or to provide indemnification for the same expenses or liabilities incurred by such Fund Director are secondary), (b) that it shall be required to advance the full
amount of expenses incurred by such Fund Director and shall be liable for the full amount of all expenses, judgments, penalties, fines and amounts paid in settlement by or on behalf of any such Fund Director to the extent legally permitted and as
required by the Company’s Certificate of Incorporation or Bylaws of the Company (or any agreement between the Company and such Fund Director), without regard to any rights such Fund Director may have against the Fund Indemnitors, and,
(c) that it irrevocably waives, relinquishes and releases the Fund Indemnitors from any and all claims against the Fund Indemnitors for contribution, subrogation or any other recovery of any kind in respect thereof. The Company further
agrees that no advancement or payment by the Fund Indemnitors on behalf of any such Fund Director with respect to any claim for which such Fund Director has sought indemnification from the Company shall affect the foregoing and the Fund Indemnitors
shall have a right of contribution and/or be subrogated to the extent of such advancement or payment to all of the rights of recovery of such Fund Director against the Company. 

2.10 Employee Stock. Unless otherwise approved by the Board of Directors, all future employees and consultants of the Company who
purchase, receive options to purchase, or receive awards of shares of the Company’s capital stock after the date hereof (other than as a result of such employee’s or consultant’s participation in a bona fide financing transaction
conducted by the Company) shall be required to execute restricted stock or option agreements, as applicable, providing for: (i) vesting of shares over a four (4) year period, with the first twenty-five percent (25%) of such shares
vesting following twelve (12) months of continued employment or service, and the remaining shares vesting in equal monthly installments over the following thirty-six (36) months; and (ii) a market stand-off provision prohibiting such
persons from transferring, hedging or otherwise disposing any capital stock following an IPO for a period specified by the Company and the managing underwriting not to exceed 180 days (or such other period as may be requested by the Company or an
underwriter to accommodate regulatory restrictions on (1) the publication or other distribution of research reports and (2) analyst recommendations and opinions, including, but not limited to, the restrictions contained in FINRA Rule
2711(f)(4) or NYSE Rule 472(f)(4), or any successor provisions or amendments thereto). 
 2.11 Termination of Certain Covenants. The
covenants set forth in this Section 2 shall terminate and be of no further force or effect upon the earlier of: (i) the consummation of the sale of securities pursuant to a Qualifying IPO; or (ii) the first date upon which none of the
Registrable Securities are outstanding. 
 3. RESTRICTIONS ON TRANSFER. 

3.1 General Restrictions. Each Holder agrees not to make any disposition of all or any portion of its Registrable Securities unless and
until: 

 (a) 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; 
 (b) The transfer is
completed in compliance with an applicable exemption from registration under the Securities Act or pursuant to a “no action” letter from the SEC that the proposed sale, pledge, or transfer of such Restricted Securities without registration
will not result in a recommendation by the staff of the SEC that action be taken with respect thereto; or 
 (c) (i) The transferee
has agreed in writing to be bound by the terms of this Agreement; (ii) such 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 (iii) if reasonably requested by the Company, such Holder shall have furnished the Company with an opinion of counsel, reasonably satisfactory to the Company, that such disposition will not require registration of such
shares under the Securities Act. 
 3.2 Exceptions. Notwithstanding the provisions of Section 3.1, no such restriction shall
apply to a transfer that is: (i) in compliance with SEC Rule 144; (ii) by a partnership transferring to its partners or former partners in accordance with partnership interests; (iii) by a corporation transferring to a wholly owned
subsidiary or a parent corporation that owns all of the capital stock of the Holder; (iv) by a limited liability company transferring to its members or former members in accordance with their interest in the limited liability company; or
(v) by an individual transferring to the Holder’s family member or trust for the benefit of an individual Holder or such Holder’s family member(s); provided, however, that in the case of a transfer pursuant to clauses
(ii) through (v) above the transferee agrees in writing to be subject to the terms of this Agreement to the same extent as if he, she or it were an original Holder hereunder. The Company will not require a legal opinion with respect to any
transfers contemplated by this Section 3.2. 
 3.3 Legends. Each certificate representing Registrable Securities shall be
stamped or otherwise imprinted with legends substantially similar to the following (in addition to any legend required under applicable state securities laws): 

THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES
ACT”). THEY MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED OR HYPOTHECATED IN THE ABSENCE OF A REGISTRATION STATEMENT IN EFFECT WITH RESPECT TO THE SECURITIES UNDER THE SECURITIES ACT OR AN OPINION OF COUNSEL SATISFACTORY TO THE COMPANY THAT SUCH
REGISTRATION IS NOT REQUIRED OR UNLESS SOLD PURSUANT TO RULE 144 OF THE SECURITIES ACT. 
 THE SALE, PLEDGE, HYPOTHECATION OR TRANSFER OF THE
SECURITIES REPRESENTED BY THIS CERTIFICATE IS SUBJECT TO THE TERMS AND CONDITIONS OF THAT CERTAIN INVESTORS’ RIGHTS AGREEMENT BY AND BETWEEN THE SHAREHOLDER AND THE COMPANY. COPIES OF SUCH AGREEMENT MAY BE OBTAINED UPON WRITTEN REQUEST TO THE
SECRETARY OF THE COMPANY. 
 3.4 Removal of Legends. The Company shall be obligated to promptly reissue unlegended certificates at
the request of any Holder thereof if the Company has completed the initial public offering of shares of Common Stock registered under the Securities Act and the Holder shall have obtained an opinion of

 
counsel (which counsel may be counsel to the Company) reasonably acceptable to the Company to the effect that the securities proposed to be disposed of may lawfully be so disposed of without
registration, qualification and legend. In addition, any legend endorsed on an instrument pursuant to applicable state securities laws and the stop-transfer instructions with respect to such securities shall be removed upon receipt by the Company of
an order of the appropriate blue sky authority authorizing such removal. 
 4. MISCELLANEOUS. 

4.1 Successors and Assigns. Except as otherwise provided herein, the terms and conditions of this Agreement shall inure to the benefit
of and be binding upon the respective successors and assigns of the parties (including transferees of any shares of Registrable Securities). Nothing in this Agreement, express or implied, is intended to confer upon any party other than the parties
hereto or their respective successors and assigns any rights, remedies, obligations, or liabilities under or by reason of this Agreement, except as expressly provided in this Agreement. 

4.2 Aggregation of Stock. All shares of Registrable Securities held or acquired by affiliated entities or persons shall be aggregated
together for the purpose of determining the availability of any rights under this Agreement. 
 4.3 Notices. All notices required or
permitted hereunder shall be in writing and shall be deemed effectively given: (i) upon personal delivery to the party to be notified; (ii) when sent by electronic mail or confirmed facsimile, if sent during normal business hours of the
recipient or, if not, then on the next business day; (iii) five (5) days after having been sent by registered or certified mail, return receipt requested, postage prepaid; or (iv) one (1) 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 to each of the Investors, as applicable, at the respective addresses set forth on the signature
page of this document or at such other address(es) as the Company or any such Investor may designate by ten (10) days advance written notice to the other parties hereto. 

4.4 Expenses. If any action at law or in equity is necessary to enforce or interpret the terms of this Agreement, the prevailing party
shall be entitled to reasonable attorneys’ fees, costs and necessary disbursements in addition to any other relief to which such party may be entitled. 

4.5 Amendments and Waivers. Prior to a Qualifying IPO, any term of this Agreement may be amended and the observance of any term of this
Agreement may be waived (either generally or in a particular instance and either retroactively or prospectively), only with the written consent of the Company and the Requisite Holders. Thereafter, any term of this Agreement may be amended and the
observance of any term of this Agreement may be waived (either generally or in a particular instance and either retroactively or prospectively), only with the written consent of the Company and the holders of a majority of the Registrable Securities
then outstanding. Notwithstanding the foregoing, Section 1.8 shall not be amended or waived without the written consent of each of the Novo Major Investor, RiverVest Major Investor, TPG Major Investor, Domain Major Investor, Avalon Major
Investor, OrbiMed Major Investor if the effect of such amendment would be to make any liability of a Holder under Section 1.8 joint with any other Holder or to increase the cap on indemnity under Section 1.8 in excess of the net proceeds
from the offering received by a Holder; further this sentence shall not be amended or waived without the written consent of each the Novo Major Investor, RiverVest Major Investor, TPG Major Investor, Domain Major Investor, Avalon Major Investor,
OrbiMed Major Investor. Purchasers purchasing shares of Series D Preferred Stock under the Purchase Agreement may become parties to this Agreement by executing a counterpart of this Agreement and Exhibit A hereto may be amended by the Company to add
information regarding such purchasers, in each case without any consent or approval of any other Investor. Any amendment or waiver effected in accordance 

 
with this paragraph shall be binding upon each holder of any Registrable Securities then outstanding, each future holder of all such Registrable Securities, and the Company. 

4.6 Severability. If one or more provisions of this Agreement are held by a court of competent jurisdiction to be unenforceable under
applicable legal requirements, the parties agree to promptly renegotiate such provision in good faith. In the event that the parties cannot reach a mutually agreeable and enforceable replacement in writing for such provision, then: (i) such
provision shall be excluded from this Agreement; (ii) the balance of this Agreement shall be interpreted as if such provision were so excluded; and (iii) the balance of this Agreement shall be enforceable in accordance with its terms. 

4.7 Governing Law. This Agreement and any controversy arising out of or relating to this Agreement shall be governed by and construed
in accordance with the General Corporation Law of the State of Delaware as to matters within the scope thereof, and as to all other matters shall be governed by and construed under the laws of the State of California without reference to its
principles of conflict of laws. 
 4.8 Entire Agreement. This Agreement, together with the exhibits and schedules hereto, constitutes
the entire agreement among the parties, and no party shall be liable or bound to any other party in any manner by any warranties, representations, or covenants except as specifically set forth herein or therein. Upon the effectiveness of this
Agreement, the Original Agreement shall be deemed amended and restated and superseded and replaced in its entirety by this Agreement, and shall be of no further force or effect. 

4.9 Counterparts; Execution by Facsimile. This Agreement may be executed in two or more counterparts, each of which shall be deemed an
original, but all of which together shall constitute one and the same instrument. Delivery of an executed counterpart of this Agreement by facsimile (or similar electronic means) shall be equally as effective as delivery of an original executed
counterpart of this Agreement.
