ARTICLE 2 

REGISTRATION RIGHTS 

2.1 Demand Registration. 

2.1.1 Form S-1 Demand. If at any time one hundred eighty (180) days after the effective
date of the registration statement for the IPO, the Company receives a request from a Demanding Holder that the Company file a Form S-1 registration statement with respect to any Registrable Securities then
outstanding, then the Company shall (a) within ten (10) days after the date such request is given, give a Demand Notice to all Holders other than the Initiating Holders; and (b) use reasonable best efforts to as soon as practicable,
and in any event within sixty (60) days after the date such request is given by the Initiating Holders, file a Form S-1 registration statement under the Securities Act covering all Registrable Securities
that the Initiating Holders requested to be registered and any additional Registrable Securities requested to be included in such registration by any other Holders, as specified by notice given by each such Holder to the Company within twenty
(20) days after the date the Demand Notice is given, and in each case, subject to the limitations of Section 2.1.3 and Section 2.3. 

2.1.2 Form S-3 Demand. If at any time when the Company is eligible to use a Form S-3 registration statement, the Company receives a request from a Demanding Holder that the Company file a Form S-3 registration statement (including by means of a shelf
registration statement pursuant to Rule 415 under the Securities Act providing for an offering to be made on a continuous basis if so requested) with respect to any or all of the outstanding Registrable Securities of such Holders, then the Company
shall (a) within ten (10) days after the date such request is given, give a Demand Notice to all Holders other than the Initiating Holders; and (b) use reasonable best efforts to as soon as practicable, and in any event within
forty-five (45) days after the date such request is given by the Initiating Holders, file a Form S-3 registration statement under the Securities Act covering all Registrable Securities requested to be

Section 2.1.3 and Section 2.3. 

  
 5 

 2.1.3 Notwithstanding the foregoing obligations, if the Company furnishes to Holders
requesting a registration pursuant to this Section 2.1 a certificate signed by the Company’s chief executive officer stating that in the good faith judgment of the Board it would be materially detrimental to the
Company and its equityholders for such registration statement to either become effective or remain effective for as long as such registration statement otherwise would be required to remain effective, because such action would (a) materially
interfere with a significant acquisition, corporate reorganization, or other similar transaction involving the Company; (b) require premature disclosure of material information that the Company has a bona fide business purpose for preserving as
confidential; or (c) render the Company unable to comply with requirements under the Securities Act or Exchange Act, then the Company shall have the right to defer taking action with respect to such filing, and any time periods with respect to
filing or effectiveness thereof shall be tolled correspondingly, for a period of not more than ninety (90) days after the request of the Initiating Holders is given; provided, however, that (i) the
Company may not invoke this right more than once in any twelve (12) month period and (ii) the Company shall not register any securities for its own account or that of any other equityholder during such ninety (90) day period other
than an Excluded Registration. 
 2.1.4 Limitations. The Company shall not be obligated to effect, or to take any action to effect, any
registration pursuant to Section 2.1.1: (a) during the period that is sixty (60) days before the Company’s good faith estimate of the date of filing of, and ending on a date that is one hundred eighty
(180) days after the effective date of, a Company-initiated registration, provided, that the Company is actively employing in good faith reasonable best efforts to cause such registration statement to become effective; (b) after the
Company has effected four (4) registrations pursuant to Section 2.1.1; (c) for a six (6) month period after the Company has effected a registration pursuant to Section 2.1.1; or
(d) if the Initiating Holders propose to dispose of Registrable Securities that may be immediately registered on Form S-3 pursuant to a request made pursuant to Section 2.1.2.
The Company shall not be obligated to effect, or to take any action to effect, any registration pursuant to Section 2.1.2: (i) during the period that is thirty (30) days before the Company’s good faith estimate of
the date of filing of, and ending on a date that is ninety (90) days after the effective date of, a Company-initiated registration, provided, that the Company is actively employing in good faith reasonable best efforts to cause such
registration statement to become effective; or (ii) if the Company has effected two (2) registrations pursuant to Section 2.1.2 within the six (6) month period immediately preceding the date of such request.
A registration shall not be counted as “effected” for purposes of this Section 2.1.4 until such time as the applicable registration statement has been declared effective by the SEC, unless the Initiating Holders
withdraw their request for such registration, elect not to pay the registration expenses therefor, and forfeit their right to one registration on Form S-1 or one registration on Form S-3 during the applicable six (6) month period immediately following the date of the initial registration request, as applicable, pursuant to Section 2.6, in which case such withdrawn
registration statement shall be counted as “effected” for purposes of this Section 2.1.4. 
 2.2
Company Registration. If the Company proposes to register (including, for this purpose, a registration effected by the Company for equityholders other than the Holders, whether as part of an underwritten offering of Registrable Securities
included by the Company on a shelf registration statement or otherwise) any of its Common Equity under the Securities Act in connection with the public offering of such securities solely for cash (other than in an 

  
 6 

 
Excluded Registration), the Company shall, at such time, promptly give each Holder notice of such registration. Upon the request of each Holder given within twenty (20) days after such
notice is given by the Company, the Company shall, subject to the provisions of Section 2.3, cause to be registered all of the Registrable Securities that each such Holder has requested to be included in such registration.
The Company shall have the right to terminate or withdraw any registration initiated by it under this Section 2.2 before the effective date of such registration, whether or not any Holder has elected to include Registrable
Securities in such registration. The expenses (other than Selling Expenses) of such withdrawn registration shall be borne by the Company in accordance with Section 2.6. 

2.3 Underwriting Requirements.  

2.3.1 Inclusion. If, pursuant to Section 2.1, 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 2.1, and the Company shall include such information in the Demand Notice.
The underwriter(s) will be selected by the Board, provided such underwriter(s) is reasonably acceptable to the Initiating Holders. In such event, the right of any Holder to include such Holder’s Registrable Securities in such
registration shall be conditioned upon such Holder’s participation in such underwriting. All Holders proposing to distribute their securities through such underwriting shall (together with the Company as provided in
Section 2.4.5) enter into an underwriting agreement in customary form with the underwriter(s) selected for such underwriting. Notwithstanding any other provision of this Section 2.3, if the
managing underwriter(s) advise(s) the Initiating Holders in writing that marketing factors require a limitation on the number of equity securities to be underwritten, then the Initiating Holders shall so advise all Holders of Registrable Securities
that otherwise would be underwritten pursuant hereto, and the number of Registrable Securities that may be included in the underwriting shall be allocated among such Holders of Registrable Securities, including the Initiating Holders, in proportion
(as nearly as practicable) to the number of Registrable Securities owned or held by each Holder or in such other proportion as shall mutually be agreed to by all such selling Holders; provided, however, that the number of Registrable Securities
owned or held by the Holders to be included in such underwriting shall not be reduced unless all other securities are first entirely excluded from the underwriting. To facilitate the allocation of equity securities in accordance with the above
provisions, the Company or the underwriters may round the number of equity securities allocated to any Holder to the nearest one hundred (100) equity securities. 

2.3.2 Underwriter Cutback. In connection with any offering involving an underwriting of shares of the Company’s equity pursuant to
Section 2.2, the Company shall not be required to include any of the Holders’ Registrable Securities in such underwriting unless the Holders accept the terms of the underwriting as agreed upon between the Company and
its underwriters. If the total number of securities, including Registrable Securities, requested by equityholders to be included in such offering exceeds the number of securities to be sold (other than by the Company) that the underwriters in their
reasonable discretion determine is compatible with the success of the offering, then the Company shall be required to include in the offering only that number of such securities, including Registrable Securities, which the underwriters and the
Company in their sole discretion determine will not jeopardize the success of the offering (after reasonable consultation with the Holders who have elected to include 

  
 7 

 
Registrable Securities in such registration). If the underwriters determine that less than all of the Registrable Securities requested to be registered can be included in such offering, then the
Registrable Securities that are included in such offering shall be allocated among the selling Holders in proportion (as nearly as practicable to) the number of Registrable Securities owned or held by each selling Holder or in such other proportions
as shall mutually be agreed to by all such selling Holders. To facilitate the allocation of equity securities in accordance with the above provisions, the Company or the underwriters may round the number of equity securities allocated to any Holder
to the nearest one hundred (100) equity securities. Notwithstanding the foregoing, in no event shall (a) the number of Registrable Securities included in the offering be reduced unless all other securities (other than securities to be sold
by the Company) are first entirely excluded from the offering or (b) the number of Registrable Securities included in the offering be reduced below thirty percent (30%) of the total number of securities included in such offering, unless such
offering is the IPO, in which case the selling Holders may be excluded further if the underwriters make the determination described above and no other equityholder’s securities are included in such offering. For purposes of the provision in
this Section 2.3.2 concerning apportionment, for any selling Holder that is a partnership, limited liability company, or corporation, the partners, members, retired partners, retired members, stockholders, and Affiliates of
such Holder, or the estates and Immediate Family Members of any such partners, retired partners, members, and retired members and any trusts for the benefit of any of the foregoing Persons, shall be deemed to be a single “selling Holder,”
and any pro rata reduction with respect to such “selling Holder” shall be based upon the aggregate number of Registrable Securities owned or held by all Persons included in such “selling Holder,” as defined in this sentence. 

2.3.3 Registration Not Effected. For purposes of Section 2.1, a registration shall not be counted as
“effected” if (a) the registration statement relating thereto does not become effective or is not maintained effective for the period required pursuant to this ARTICLE 2, (b) the offering of the Registrable Securities
pursuant to such registration statement is subject to a stop order, injunction, or similar order or requirement of the SEC or (c) as a result of an exercise of the underwriter’s cutback provisions in
Section 2.3.1, fewer than seventy five percent (75%) of the total number of Registrable Securities that Holders have requested to be included in such registration statement are actually included. 

2.4 Obligations of the Company. Whenever required under this ARTICLE 2 to effect the registration of any Registrable
Securities, the Company shall use reasonable best efforts to effect the registration and sale of such Registrable Securities in accordance with the intended method of disposition thereof, and pursuant thereto the Company shall as expeditiously as
reasonably possible: 
 2.4.1 prepare and file with the SEC a registration statement with respect to such Registrable Securities and use its
reasonable best efforts to cause such registration statement to become effective as promptly as practicable, and, upon the request of a Demanding Holder registered thereunder, keep such registration statement effective for a period of up to one
hundred twenty (120) days or, if earlier, until the distribution contemplated in the registration statement has been completed; provided, however, that (a) such 120-day period shall be
extended for a period of time equal to the period the Holder refrains, at the request of an underwriter of Common Equity (or other securities) of the Company, from selling any securities included in 

  
 8 

 
such registration, and (b) in the case of any registration of Registrable Securities on Form S-3 that are intended to be offered on a continuous or
delayed basis, subject to compliance with applicable SEC rules, such registration statement shall be kept effective continually until all such Registrable Securities are sold; 

2.4.2 prepare and file with the SEC such amendments and supplements to such registration statement, the prospectus and, if required, any Free
Writing Prospectus used in connection with such registration statement as may be necessary to comply with the Securities Act in order to enable the disposition of all securities covered by such registration statement; 

2.4.3 furnish to the selling Holders such numbers of copies of a prospectus, including a preliminary prospectus and any Free Writing
Prospectus, as required by the Securities Act, and such other documents as the Holders may reasonably request in order to facilitate their disposition of their Registrable Securities; 

2.4.4 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 selling Holders; provided that the Company shall not be required 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; 

2.4.5 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 underwriter(s) of such offering; 
 2.4.6 cause senior representatives of the Company to participate in any
“road show” or “road shows” reasonably requested by any underwriter of an underwritten or “best efforts” offering of any Registrable Securities;

such securities are being sold through underwriters, (a) 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 (b) a letter dated as of such date, from the independent public accountants of the Company, in form and substance as is customarily given by independent public accountants
to underwriters in an underwritten public offering addressed to the underwriters; 
 2.4.8 use its reasonable best efforts to cause all such
Registrable Securities covered by such registration statement to be listed on a national securities exchange or trading system and each securities exchange and trading system (if any) on which similar securities issued by the Company are then
listed; 
 2.4.9 provide a transfer agent and registrar for all Registrable Securities registered pursuant to this Agreement and provide a
CUSIP number for all such Registrable Securities, in each case not later than the effective date of such registration; 

  
 9 

 2.4.10 promptly make available for inspection by the selling Holders, any managing
underwriter(s) participating in any disposition pursuant to such registration statement, and any attorney or accountant or other agent retained by any such underwriter or selected by the selling Holders, all financial and other records, pertinent
corporate documents, and properties of the Company, and cause the Company’s officers, directors, employees, and independent accountants to supply all information reasonably requested by any such seller, underwriter, attorney, accountant, or
agent, in each case, as necessary or advisable to verify the accuracy of the information in such registration statement and to conduct appropriate due diligence in connection therewith; 

2.4.11 notify each selling Holder, promptly after the Company receives notice thereof, of the time when such registration statement has been

supplement such registration statement or prospectus or Free-Writing Prospectus; 
 2.4.13 use its reasonable best efforts to obtain for the
underwriters one or more “cold comfort” letters, dated the effective date of the related registration statement (and, if such registration includes an underwritten public offering, dated the date of the closing under the underwriting
agreement), signed by the Company’s independent public accountants in customary form and covering such matters of the type customarily covered by “cold comfort” letters;

submitted to the Company in accordance with Section 2.1, if so requested, file an Automatic Shelf Registration Statement to effect such registration; and 

2.4.16 if at any time when the Company is required to re-evaluate its well-known seasoned issuer status
for purposes of an outstanding Automatic Shelf Registration Statement used to effect a request for registration in accordance with Section 2.1.2 the Company determines that it is not a well-known seasoned issuer and

indemnity or contribution under Sections 2.8.2 and 2.8.4 exceed the proceeds from the offering received by such Holder (net of any Selling Expenses paid by such Holder), except in the case of fraud or willful misconduct by such Holder.

 2.8.3 Procedures. Promptly after receipt by an indemnified party under this Section 2.8 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 2.8, give the indemnifying party 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 to which notice has been given, 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 that 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 action. The failure to give 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 2.8, solely to the extent that
such failure prejudices the indemnifying party’s ability to defend such action. 

  
 12 

 2.8.4 Contribution. To provide for just and equitable contribution to joint liability
under the Securities Act in any case in which either (y) any party otherwise entitled to indemnification hereunder makes a claim for indemnification pursuant to this Section 2.8 but it is judicially determined (by the
entry of a final judgment or decree by a court of competent jurisdiction and the expiration of time to appeal or the denial of the last right of appeal) that such indemnification may not be enforced in such case, notwithstanding the fact that this
Section 2.8 provides for indemnification in such case, or (z) contribution under the Securities Act may be required on the part of any party hereto for which indemnification is provided under this
Section 2.8, then, and in each such case, such parties will contribute to the aggregate losses, claims, damages, liabilities, or expenses to which they may be subject (after contribution from others) in such proportion as
is appropriate to reflect the relative fault of each of the indemnifying party and the indemnified party in connection with the statements, omissions, or other actions that resulted in such loss, claim, damage, liability, or expense, as well as to
reflect 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 allegedly untrue statement of a material
fact, or the omission or alleged omission of 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; provided, however, that: 
 (a) in any such case, (i) no
Holder will be required to contribute any amount in excess of the public offering price of all such Registrable Securities offered and sold by such Holder pursuant to such registration statement, and (ii) no Person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act) will be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation; and 

(b) in no event shall a Holder’s liability pursuant to this Section 2.8.4, when combined with the amounts paid or payable by such
Holder pursuant to Section 2.8.2, exceed the proceeds from the offering received by such Holder (net of any Selling Expenses paid by such Holder), except in the case of fraud or willful misconduct by such Holder. 

2.8.5 Underwriting Agreement Controls. Notwithstanding the foregoing, to the extent that the provisions on 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. 

2.8.6 Survival. Unless otherwise superseded by an underwriting agreement entered into in connection with the underwritten public
offering, the obligations of the Company and Holders under this Section 2.8 shall survive the completion of any offering of Registrable Securities in a registration under this ARTICLE 2, and otherwise shall survive
the termination of this Agreement.  
 2.9 Reports under the Exchange Act. With a view to making available to the
Holders the benefits of 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 shall: 
 2.9.1 use reasonable best efforts to make and keep available adequate current
public information, as those terms are understood and defined in SEC Rule 144, at all times after the effective date of the registration statement filed by the Company for the IPO; 

  
 13 

 2.9.2 use reasonable best efforts to 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 (at any time after the Company has become subject to such reporting requirements); and 

2.9.3 furnish to any Holder, so long as the Holder owns any Registrable Securities, forthwith upon request (a) to the extent accurate, 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 registration statement filed by the Company for the IPO), the Securities
Act, and the Exchange Act (at any time after the Company has become subject to such reporting requirements), or that it qualifies as a registrant whose securities may be resold pursuant to Form S-3 (at any
time after the Company so qualifies); and (b) such other information as may be reasonably requested in availing any Holder of any rule or regulation of the SEC that permits the selling of any such securities without registration (at any time
after the Company has become subject to the reporting requirements under the Exchange Act) or pursuant to Form S-3 (at any time after the Company so qualifies to use such form). 

2.10 Limitations on Subsequent Registration Rights. From and after the date of this Agreement, without the prior written consent
of the holders of a majority of the Registrable Securities then outstanding, the Company shall not grant registration rights or similar rights to any Person that have, or would have, priority over, or be pari passu with, the registration rights to
be granted to the holders of Registrable Securities pursuant to this Agreement. For clarity, the Company shall not enter into any agreement with any holder or prospective holder of any securities of the Company that would allow such holder or
prospective holder to include such securities in any registration if such agreement (a) would allow such holder or prospective holder to include a portion of its securities in any “piggyback” registration if such inclusion could
reduce the number of Registrable Securities that selling Holders could be entitled to include in such registration under Sections 2.2 and 2.3 hereof, (b) would allow such holder or prospective holder to initiate a demand for
registration of any of its securities at a time earlier than the Demanding Holders can demand registration under Section 2.1 hereof or (c) would allow such holder or prospective holder to include a portion of its
securities in any registration initiated pursuant to Section 2.1. 
 2.11 “Market Stand-off” Agreement. Each Holder hereby agrees that, during the Standoff Period, such Holder will not, without the prior written consent of the Company or the managing underwriter,

 2.11.1 lend, offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell,
grant any option, right, or warrant to purchase or otherwise transfer or dispose of, directly or indirectly, any Common Equity, or any securities convertible into or exercisable or exchangeable (directly or indirectly) for Common Equity, held
immediately before the effective date of the registration statement for such offering; or 
 2.11.2 enter into any swap or other arrangement
that transfers to another, in whole or in part, any of the economic consequences of ownership of such securities held immediately before the effective date of the registration statement for such offering, whether any such transaction described in
Section 2.11.1 or this Section 2.11.2 is to be settled by delivery of Common Equity or other securities, in cash, or otherwise. 

  
 14 

 The foregoing provisions of this Section 2.11 shall apply only to the IPO and
shall not apply to (a) the sale of any equity securities to an underwriter pursuant to an underwriting agreement, (b) if the Holder is a corporation, partnership, limited liability company, trust or other business entity, any transfer or
disposition of Common Equity pursuant to a distribution to the Holder’s partners, members or stockholders, subsidiaries or affiliates (as defined in Rule 405 promulgated under the Securities Act) or to any investment fund or other entity that
controls or manages the Holder (or is under common control or management with the Holder) provided that such transferee agrees to be bound by the same restrictions as are applicable to the Holder, or (c) any transfer or disposition of Common Equity
pursuant to a bona fide third party tender offer, merger, consolidation or other similar transaction made to all holders of Common Equity involving a change of control of the Company that, in each case, has been approved by the Board, provided that
all of the Holder’s shares of Common Equity subject to the restrictions in this Section 2.11 that are not so transferred, sold, tendered or otherwise disposed of remain subject to such restrictions in this Section 2.11, and, provided that in
the event that the tender offer, merger, consolidation or other such transaction is not completed, the shares of Common Equity owned by the Holder shall remain subject to the restrictions set forth in this Section 2.11, and shall be applicable to
the Holders only if all officers, directors, and equityholders individually owning more than one percent (1%) of the Company’s outstanding Common Equity are similarly bound. For purposes of this Section 2.11, the term
“Company” shall include any wholly-owned subsidiary of the Company into which the Company merges or consolidates. Any discretionary waiver or termination of the restrictions of any or all such agreements by the Company or the underwriters
(other than discretionary waivers for requests based on financial hardship for the sale of equity securities having an aggregate sales price not exceeding $100,000 per Holder) shall apply pro rata to all Holders subject to such agreements, based on
the number of equity securities subject to such agreements. In order to enforce the foregoing covenant, the Company shall have the right to place restrictive legends on the certificates representing the equity securities subject to this
Section 2.11 and to impose stop transfer instructions with respect to such equity securities until the end of such period. The underwriters in connection with such registration are intended
third-party beneficiaries of this Section 2.11 and shall have the right, power, and authority to enforce the provisions hereof as though they were a party hereto. Each Holder further
agrees to execute such agreements as may be reasonably requested by the underwriters in connection with such registration that are consistent with this Section 2.11 or that are necessary to give further effect thereto.
Notwithstanding anything herein to the contrary, the provisions of this Section 2.11 shall not apply to any equity securities purchased by a Holder in the IPO. 

ARTICLE 3 

TERMINATION 
 The right of any
Holder to request registration or inclusion of Registrable Securities in any registration pursuant to Section 2.1 or Section 2.2 shall terminate upon the earliest to occur of: (a) when (i)
such Holder and its Affiliates hold less than ten percent (10%) of the outstanding capital stock of the Company in the aggregate and are not serving as a director or officer of the Company, or such Holder and its Affiliates can obtain from reputable
legal counsel (as reasonably determined by such Holder) using commercially reasonable efforts a legal opinion that each of such Holder and its Affiliates is not an “affiliate” of the Company as such term is defined under SEC Rule 144 and
(ii) all of such Holder’s Registrable Securities and such Holder’s Affiliates’ Registrable Securities could be sold without any restriction on volume or manner of sale in any three-month period under SEC Rule 144 or any successor; and
(b) upon a Change of Control. All of the rights of a Holder, other than any right of such Holder to enforce the obligations of the Company to such Holder arising under Section 2.6 or Section 2.8 under this Agreement,
shall terminate automatically at such time as such Holder together with its affiliates no longer owns (either directly or beneficially as the result of the ownership of shares of any holding company) at least two percent (2%) of the Registrable
Securities. 
 ARTICLE 4

(v) to accelerate at any time the exercisability or vesting of all or any portion of any Award; 

(vi) subject to the provisions of Section 5(c), to extend at any time the period in which Stock Options may be exercised; and 

(vii) at any time to adopt, alter and repeal such rules, guidelines and practices for administration of the Plan and for its own acts and
proceedings as it shall deem advisable; to interpret the terms and provisions of the Plan and any Award (including related written instruments); to make all determinations it deems advisable for the administration of the Plan; to decide all disputes
arising in connection with the Plan; and to otherwise supervise the administration of the Plan. 
 All decisions and interpretations of the
Administrator shall be binding on all persons, including the Company and Plan grantees. 
 (c) Delegation of Authority to Grant
Awards. Subject to applicable law, the Administrator, in its discretion, may delegate to a committee consisting of one or more officers of the Company including the Chief Executive Officer of the Company all or part of the Administrator’s
authority and duties with respect to the granting of Awards to individuals who are (i) not subject to the reporting and other provisions of Section 16 of the Exchange Act and (ii) not members of the delegated committee. Any such
delegation by the Administrator shall include a limitation as to the amount of Stock underlying Awards that may be granted during the 

  
 4 

 
period of the delegation and shall contain guidelines as to the determination of the exercise price and the vesting criteria. The Administrator may revoke or amend the terms of a delegation at
any time but such action shall not invalidate any prior actions of the Administrator’s delegate or delegates that were consistent with the terms of the Plan. 

(d) Award Certificate. Awards under the Plan shall be evidenced by Award Certificates that set forth the terms, conditions and
limitations for each Award which may include, without limitation, the term of an Award and the provisions applicable in the event the employment (or other Service Relationship) terminates. 

(e) Indemnification. Neither the Board nor the Administrator, nor any member of either or any delegate thereof, shall be liable for any
act, omission, interpretation, construction or determination made in good faith in connection with the Plan, and the members of the Board and the Administrator (and any delegate thereof) shall be entitled in all cases to indemnification and
reimbursement by the Company in respect of any claim, loss, damage or expense (including, without limitation, reasonable attorneys’ fees) arising or resulting therefrom to the fullest extent permitted by law and/or under the Company’s
articles or bylaws or any directors’ and officers’ liability insurance coverage which may be in effect from time to time and/or any indemnification agreement between such individual and the Company. 

(f) Non-U.S. Award Recipients. Notwithstanding any provision of the Plan to the contrary, in
order to comply with the laws in other countries in which the Company and its Affiliates operate or have employees or other individuals eligible for Awards, the Administrator, in its sole discretion, shall have the power and authority to:
(i) determine which Affiliates shall be covered by the Plan; (ii) determine which individuals outside the United States are eligible to participate in the Plan; (iii) modify the terms and conditions of any Award granted to individuals
outside the United States to comply with applicable laws; (iv) establish subplans and modify exercise procedures and other terms and procedures, to the extent the Administrator determines such actions to be necessary or advisable (and such
subplans and/or modifications shall be incorporated into and made part of this Plan); provided, however, that no such subplans and/or modifications shall increase the share limitations contained in Section 3(a) hereof; and (v) take any
action, before or after an Award is made, that the Administrator determines to be necessary or advisable to obtain approval or comply with any local governmental regulatory exemptions or approvals. Notwithstanding the foregoing, the
Administrator may not take any actions hereunder, and no Awards shall be granted, that would violate the Exchange Act or any other applicable United States securities law, the Code, or any other applicable United States governing statute or law.

 SECTION 3. STOCK ISSUABLE UNDER THE PLAN; MERGERS; SUBSTITUTION 

(a) Stock Issuable. The maximum number of shares of Stock reserved and available for issuance under the Plan shall be 11,500,000 shares
(the “Initial Limit”), subject to adjustment as provided in this Section 3, plus on January 1, 2020 and each January 1 thereafter, the number of shares of Stock reserved and available for issuance under the Plan shall be
cumulatively increased by 5 percent of the number of shares of Stock issued and outstanding on the immediately preceding December 31 or such lesser number of shares of Stock as determined by the Administrator in its sole discretion (the
“Annual Increase”). Subject to such overall 

  
 5 

 
limitation, the maximum aggregate number of shares of Stock that may be issued in the form of Incentive Stock Options shall not exceed the Initial Limit cumulatively increased on January 1,
2020 and on each January 1 thereafter by the lesser of the Annual Increase for such year or 11,500,000 shares of Stock, subject in all cases to adjustment as provided in this Section 3. For purposes of this limitation, the shares of Stock
underlying any Awards under the Plan that are forfeited, canceled, held back upon exercise of an Option or settlement of an Award to cover the exercise price or tax withholding, reacquired by the Company prior to vesting, satisfied without the
issuance of Stock or otherwise terminated (other than by exercise) shall be added back to the shares of Stock available for issuance under the Plan and, to the extent permitted under Section 422 of the Code and the regulations promulgated
thereunder, the shares of Stock that may be issued as Incentive Stock Options. In the event the Company repurchases shares of Stock on the open market, such shares shall not be added to the shares of Stock available for issuance under the Plan.
Subject to such overall limitations, shares of Stock may be issued up to such maximum number pursuant to any type or types of Award. The shares available for issuance under the Plan may be authorized but unissued shares of Stock or shares of Stock
reacquired by the Company. 
 (b) Maximum Awards to Non-Employee Directors. Notwithstanding
anything to the contrary in this Plan, the value of all Awards awarded under this Plan and all other cash compensation paid by the Company to any Non-Employee Director in any calendar year shall not exceed
$1,250,000. For the purpose of this limitation, the value of any Award shall be its grant date fair value, as determined in accordance with ASC 718 or successor provision but excluding the impact of estimated forfeitures related to service-based
vesting provisions. 
 (c) Changes in Stock. Subject to Section 3(d) hereof, if, as a result of any reorganization,
recapitalization, reclassification, stock dividend, stock split, reverse stock split or other similar change in the Company’s capital stock, the outstanding shares of Stock are increased or decreased or are exchanged for a different number or
kind of shares or other securities of the Company, or additional shares or new or different shares or other securities of the Company or other non-cash assets are distributed with respect to such shares of
Stock or other securities, or, if, as a result of any merger or consolidation, sale of all or substantially all of the assets of the Company, the outstanding shares of Stock are converted into or exchanged for securities of the Company or any
successor entity (or a parent or subsidiary thereof), the Administrator shall make an appropriate or proportionate adjustment in (i) the maximum number of shares reserved for issuance under the Plan, including the maximum number of shares that
may be issued in the form of Incentive Stock Options, (ii) the number and kind of shares or other securities subject to any then outstanding Awards under the Plan, (iii) the repurchase price, if any, per share subject to each outstanding
Restricted Stock Award, and (iv) the exercise price for each share subject to any then outstanding Stock Options and Stock Appreciation Rights under the Plan, without changing the aggregate exercise price (i.e., the exercise price multiplied by
the number of shares subject to Stock Options and Stock Appreciation Rights) as to which such Stock Options and Stock Appreciation Rights remain exercisable. The Administrator shall also make equitable or proportionate adjustments in the number of
shares subject to outstanding Awards and the exercise price and the terms of outstanding Awards to take into consideration cash dividends paid other than in the ordinary course or any other extraordinary corporate event. The adjustment by the
Administrator shall be final, binding and conclusive. No fractional shares of Stock shall be issued under the Plan resulting from any such adjustment, but the Administrator in its discretion may make a cash payment in lieu of fractional shares. 

  
 6 

 (d) Mergers and Other Transactions. In the case of and subject to the consummation of
a Sale Event, the parties thereto may cause the assumption or continuation of Awards theretofore granted by the successor entity, or the substitution of such Awards with new Awards of the successor entity or parent thereof, with appropriate
adjustment as to the number and kind of shares and, if appropriate, the per share exercise prices, as such parties shall agree. To the extent the parties to such Sale Event do not provide for the assumption, continuation or substitution of Awards,
upon the effective time of the Sale Event, the Plan and all outstanding Awards granted hereunder shall terminate. In such case, except as may be otherwise provided in the relevant Award Certificate, all Options and Stock Appreciation Rights with
time-based vesting conditions or restrictions that are not vested and/or exercisable immediately prior to the effective time of the Sale Event shall become fully vested and exercisable as of the effective time of the Sale Event, all other Awards
with time-based vesting, conditions or restrictions shall become fully vested and nonforfeitable as of the effective time of the Sale Event, and all Awards with conditions and restrictions relating to the attainment of performance goals may become
vested and nonforfeitable in connection with a Sale Event in the Administrator’s discretion or to the extent specified in the relevant Award Certificate. In the event of such termination, (i) the Company shall have the option (in its sole
discretion) to make or provide for a payment, in cash or in kind, to the grantees holding Options and Stock Appreciation Rights, in exchange for the cancellation thereof, in an amount equal to the difference between (A) the Sale Price
multiplied by the number of shares of Stock subject to outstanding Options and Stock Appreciation Rights (to the extent then exercisable at prices not in excess of the Sale Price) and (B) the aggregate exercise price of all such outstanding
Options and Stock Appreciation Rights (provided that, in the case of an Option or Stock Appreciation Right with an exercise price equal to or less than the Sale Price, such Option or Stock Appreciation Right shall be cancelled for no consideration);
or (ii) each grantee shall be permitted, within a specified period of time prior to the consummation of the Sale Event as determined by the Administrator, to exercise all outstanding Options and Stock Appreciation Rights (to the extent then
exercisable) held by such grantee. The Company shall also have the option (in its sole discretion) to make or provide for a payment, in cash or in kind, to the grantees holding other Awards in an amount equal to the Sale Price multiplied by the
number of vested shares of Stock under such Awards. 
 SECTION 4. ELIGIBILITY 

Grantees under the Plan will be such employees, Non-Employee Directors or Consultants of the Company
and its Affiliates as are selected from time to time by the Administrator in its sole discretion; provided that Awards may not be granted to employees, Directors or Consultants who are providing services only to any “parent” of the
Company, as such term is defined in Rule 405 of the Act, unless (i) the stock underlying the Awards is treated as “service recipient stock” under Section 409A or (ii) the Company has determined that such Awards are exempt
from or otherwise comply with Section 409A. 
 SECTION 5. STOCK OPTIONS 

(a) Award of Stock Options. The Administrator may grant Stock Options under the Plan. Any Stock Option granted under the Plan shall be
in such form as the Administrator may from time to time approve. 

  
 7 

 Stock Options granted under the Plan may be either Incentive Stock Options or Non-Qualified Stock Options. Incentive Stock Options may be granted only to employees of the Company or any Subsidiary that is a “subsidiary corporation” within the meaning of Section 424(f) of the
Code. To the extent that any Option does not qualify as an Incentive Stock Option, it shall be deemed a Non-Qualified Stock Option. 

Stock Options granted pursuant to this Section 5 shall be subject to the following terms and conditions and shall contain such additional
terms and conditions, not inconsistent with the terms of the Plan, as the Administrator shall deem desirable. If the Administrator so determines, Stock Options may be granted in lieu of cash compensation at the optionee’s election, subject to
such terms and conditions as the Administrator may establish. 
 (b) Exercise Price. The exercise price per share for the Stock
covered by a Stock Option granted pursuant to this Section 5 shall be determined by the Administrator at the time of grant but shall not be less than 100 percent of the Fair Market Value on the date of grant. In the case of an Incentive
Stock Option that is granted to a Ten Percent Owner, the exercise price of such Incentive Stock Option shall be not less than 110 percent of the Fair Market Value on the grant date. Notwithstanding the foregoing, Stock Options may be granted
with an exercise price per share that is less than 100 percent of the Fair Market Value on the date of grant (i) pursuant to a transaction described in, and in a manner consistent with, Section 424(a) of the Code, (ii) to
individuals who are not subject to U.S. income tax on the date of grant or (iii) the Stock Option is otherwise compliant with Section 409A. 

(c) Option Term. The term of each Stock Option shall be fixed by the Administrator, but no Stock Option shall be exercisable more than
ten years after the date the Stock Option is granted. In the case of an Incentive Stock Option that is granted to a Ten Percent Owner, the term of such Stock Option shall be no more than five years from the date of grant. 

(d) Exercisability; Rights of a Stockholder. Stock Options shall become exercisable at such time or times, whether or not in
installments, as shall be determined by the Administrator at or after the grant date. The Administrator may at any time accelerate the exercisability of all or any portion of any Stock Option. An optionee shall have the rights of a stockholder only
as to shares acquired upon the exercise of a Stock Option and not as to unexercised Stock Options. 
 (e) Method of Exercise. Stock
Options may be exercised in whole or in part, by giving written or electronic notice of exercise to the Company, specifying the number of shares to be purchased. Payment of the purchase price may be made by one or more of the following methods
except to the extent otherwise provided in the Option Award Certificate: 
 (i) In cash, by certified or bank check or other instrument
acceptable to the Administrator; 
 (ii) Through the delivery (or attestation to the ownership following such procedures as the Company may
prescribe) of shares of Stock that are not then subject to restrictions under any Company plan. Such surrendered shares shall be valued at Fair Market Value on the exercise date; 

  
 8 

 (iii) By the optionee delivering to the Company a properly executed exercise notice together
with irrevocable instructions to a broker to promptly deliver to the Company cash or a check payable and acceptable to the Company for the purchase price; provided that in the event the optionee chooses to pay the purchase price as so provided, the
optionee and the broker shall comply with such procedures and enter into such agreements of indemnity and other agreements as the Company shall prescribe as a condition of such payment procedure; or 

(iv) With respect to Stock Options that are not Incentive Stock Options, by a “net exercise” arrangement pursuant to which the
Company will reduce the number of shares of Stock issuable upon exercise by the largest whole number of shares with a Fair Market Value that does not exceed the aggregate exercise price. 

Payment instruments will be received subject to collection. The transfer to the optionee on the records of the Company or of the transfer
agent of the shares of Stock to be purchased pursuant to the exercise of a Stock Option will be contingent upon receipt from the optionee (or a purchaser acting in his or her stead in accordance with the provisions of the Stock Option) by the
Company of the full purchase price for such shares and the fulfillment of any other requirements contained in the Option Award Certificate or applicable provisions of laws (including the satisfaction of any taxes that the Company or an Affiliate is
obligated to withhold with respect to the optionee). In the event an optionee chooses to pay the purchase price by previously-owned shares of Stock through the attestation method, the number of shares of Stock transferred to the optionee upon the
exercise of the Stock Option shall be net of the number of attested shares. In the event that the Company establishes, for itself or using the services of a third party, an automated system for the exercise of Stock Options, such as a system using
an internet website or interactive voice response, then the paperless exercise of Stock Options may be permitted through the use of such an automated system. 

(f) Annual Limit on Incentive Stock Options. To the extent required for “incentive stock option” treatment under
Section 422 of the Code, the aggregate Fair Market Value (determined as of the time of grant) of the shares of Stock with respect to which Incentive Stock Options granted under this Plan and any other plan of the Company or its parent and
subsidiary corporations become exercisable for the first time by an optionee during any calendar year shall not exceed $100,000. To the extent that any Stock Option exceeds this limit, it shall constitute a
Non-Qualified Stock Option. 
 SECTION 6. STOCK APPRECIATION RIGHTS 

(a) Award of Stock Appreciation Rights. The Administrator may grant Stock Appreciation Rights under the Plan. A Stock Appreciation Right
is an Award entitling the recipient to receive shares of Stock (or cash, to the extent explicitly provided for in the applicable Award Certificate) having a value equal to the excess of the Fair Market Value of a share of Stock on the date of
exercise over the exercise price of the Stock Appreciation Right multiplied by the number of shares of Stock with respect to which the Stock Appreciation Right shall have been exercised. 

  
 9 

 (b) Exercise Price of Stock Appreciation Rights. The exercise price of a Stock
Appreciation Right shall not be less than 100 percent of the Fair Market Value of the Stock on the date of grant. 
 (c) Grant and
Exercise of Stock Appreciation Rights. Stock Appreciation Rights may be granted by the Administrator independently of any Stock Option granted pursuant to Section 5 of the Plan. 

(d) Terms and Conditions of Stock Appreciation Rights. Stock Appreciation Rights shall be subject to such terms and conditions as shall
be determined on the date of grant by the Administrator. The term of a Stock Appreciation Right may not exceed ten years. The terms and conditions of each such Award shall be determined by the Administrator, and such terms and conditions may differ
among individual Awards and grantees. 
 SECTION 7. RESTRICTED STOCK AWARDS 

(a) Nature of Restricted Stock Awards. The Administrator may grant Restricted Stock Awards under the Plan. A Restricted Stock Award is
any Award of Restricted Shares subject to such restrictions and conditions as the Administrator may determine at the time of grant. Conditions may be based on continuing employment (or other Service Relationship) and/or achievement of pre-established performance goals and objectives. 
 (b) Rights as a Stockholder. Upon the grant of
the Restricted Stock Award and payment of any applicable purchase price, a grantee shall have the rights of a stockholder with respect to the voting of the Restricted Shares and receipt of dividends; provided that if the lapse of restrictions with
respect to the Restricted Stock Award is tied to the attainment of performance goals, any dividends paid by the Company during the performance period shall accrue and shall not be paid to the grantee until and to the extent the performance goals are
met with respect to the Restricted Stock Award. Unless the Administrator shall otherwise determine, (i) uncertificated Restricted Shares shall be accompanied by a notation on the records of the Company or the transfer agent to the effect that
they are subject to forfeiture until such Restricted Shares are vested as provided in Section 7(d) below, and (ii) certificated Restricted Shares shall remain in the possession of the Company until such Restricted Shares are vested as
provided in Section 7(d) below, and the grantee shall be required, as a condition of the grant, to deliver to the Company such instruments of transfer as the Administrator may prescribe. 

(c) Restrictions. Restricted Shares may not be sold, assigned, transferred, pledged or otherwise encumbered or disposed of except as
specifically provided herein or in the Restricted Stock Award Certificate. Except as may otherwise be provided by the Administrator either in the Award Certificate or, subject to Section 15 below, in writing after the Award is issued, if a
grantee’s employment (or other Service Relationship) with the Company and its Affiliates terminates for any reason, any Restricted Shares that have not vested at the time of termination shall automatically and without any requirement of notice
to such grantee from or other action by or on behalf of, the Company be deemed to have been reacquired by the Company at its original purchase price (if any) from such grantee or such grantee’s legal representative simultaneously with such
termination of employment (or other Service Relationship), and thereafter shall cease to represent any ownership of the Company by the grantee or rights of the grantee as a stockholder. Following such deemed reacquisition of Restricted Shares that
are represented by physical certificates, a grantee shall surrender such certificates to the Company upon request without consideration. 

  
 10 

 (d) Vesting of Restricted Shares. The Administrator at the time of grant shall
specify the date or dates and/or the attainment of pre-established performance goals, objectives and other conditions on which the non-transferability of the Restricted
Shares and the Company’s right of repurchase or forfeiture shall lapse. Subsequent to such date or dates and/or the attainment of such pre-established performance goals, objectives and other conditions,
the shares on which all restrictions have lapsed shall no longer be Restricted Shares and shall be deemed “vested.” 
 SECTION 8. RESTRICTED
STOCK UNITS 
 (a) Nature of Restricted Stock Units. The Administrator may grant Restricted Stock Units under the Plan. A
Restricted Stock Unit is an Award of stock units that may be settled in shares of Stock (or cash, to the extent explicitly provided for in the Award Certificate) upon the satisfaction of such restrictions and conditions at the time of grant.
Conditions may be based on continuing employment (or other Service Relationship) and/or achievement of pre-established performance goals and objectives. The terms and conditions of each such Award shall be
determined by the Administrator, and such terms and conditions may differ among individual Awards and grantees. Except in the case of Restricted Stock Units with a deferred settlement date that complies with Section 409A, at the end of the
vesting period, the Restricted Stock Units, to the extent vested, shall be settled in the form of shares of Stock. Restricted Stock Units with deferred settlement dates are subject to Section 409A and shall contain such additional terms and
conditions as the Administrator shall determine in its sole discretion in order to comply with the requirements of Section 409A. 
 (b)
Election to Receive Restricted Stock Units in Lieu of Compensation. The Administrator may, in its sole discretion, permit a grantee to elect to receive a portion of future cash compensation otherwise due to such grantee in the form of an
award of Restricted Stock Units. Any such election shall be made in writing and shall be delivered to the Company no later than the date specified by the Administrator and in accordance with Section 409A and such other rules and procedures
established by the Administrator. Any such future cash compensation that the grantee elects to defer shall be converted to a fixed number of Restricted Stock Units based on the Fair Market Value of Stock on the date the compensation would otherwise
have been paid to the grantee if such payment had not been deferred as provided herein. The Administrator shall have the sole right to determine whether and under what circumstances to permit such elections and to impose such limitations and other
terms and conditions thereon as the Administrator deems appropriate. Any Restricted Stock Units that are elected to be received in lieu of cash compensation shall be fully vested, unless otherwise provided in the Award Certificate. 

(c) Rights as a Stockholder. A grantee shall have the rights as a stockholder only as to shares of Stock acquired by the grantee upon
settlement of Restricted Stock Units; provided, however, that the grantee may be credited with Dividend Equivalent Rights with respect to the stock units underlying his or her Restricted Stock Units, subject to the provisions of Section 11 and
such terms and conditions as the Administrator may determine. 

  
 11 

 (d) Termination. Except as may otherwise be provided by the Administrator either in
the Award Certificate or, subject to Section 15 below, in writing after the Award is issued, a grantee’s right in all Restricted Stock Units that have not vested shall automatically terminate upon the grantee’s termination of
employment (or cessation of Service Relationship) with the Company and its Affiliates for any reason. 
 SECTION 9. UNRESTRICTED STOCK AWARDS 

Grant or Sale of Unrestricted Stock. The Administrator may grant (or sell at par value or such higher purchase price determined by the
Administrator) an Unrestricted Stock Award under the Plan. An Unrestricted Stock Award is an Award pursuant to which the grantee may receive shares of Stock free of any restrictions under the Plan. Unrestricted Stock Awards may be granted in respect
of past services or other valid consideration, or in lieu of cash compensation due to such grantee. 
 SECTION 10. CASH-BASED AWARDS 

Grant of Cash-Based Awards. The Administrator may grant Cash-Based Awards under the Plan. A Cash-Based Award is an Award that entitles
the grantee to a payment in cash upon the attainment of specified performance goals, including continued employment (or other Service Relationship). The Administrator shall determine the maximum duration of the Cash-Based Award, the amount of cash
to which the Cash-Based Award pertains, the conditions upon which the Cash-Based Award shall become vested or payable, and such other provisions as the Administrator shall determine. Each Cash-Based Award shall specify a cash-denominated payment
amount, formula or payment ranges as determined by the Administrator. Payment, if any, with respect to a Cash-Based Award shall be made in accordance with the terms of the Award and may be made in cash. 

SECTION 11. DIVIDEND EQUIVALENT RIGHTS 

(a) Dividend Equivalent Rights. The Administrator may grant Dividend Equivalent Rights under the Plan. A Dividend Equivalent Right is an
Award entitling the grantee to receive credits based on cash dividends that would have been paid on the shares of Stock specified in the Dividend Equivalent Right (or other Award to which it relates) if such shares had been issued to the grantee. A
Dividend Equivalent Right may be granted hereunder to any grantee as a component of an award of Restricted Stock Units or as a freestanding award. The terms and conditions of Dividend Equivalent Rights shall be specified in the Award Certificate.
Dividend equivalents credited to the holder of a Dividend Equivalent Right may be paid currently or may be deemed to be reinvested in additional shares of Stock, which may thereafter accrue additional equivalents. Any such reinvestment shall be at
Fair Market Value on the date of reinvestment or such other price as may then apply under a dividend reinvestment plan sponsored by the Company, if any. Dividend Equivalent Rights may be settled in cash or shares of Stock or a combination thereof,
in a single installment or installments. A Dividend Equivalent Right granted as a component of an Award of Restricted Stock Units shall provide that such Dividend Equivalent Right shall be settled only upon settlement or payment of, or lapse of
restrictions on, such other Award, and that such Dividend Equivalent Right shall expire or be forfeited or annulled under the same conditions as such other Award. 

  
 12 

 (b) Termination. Except as may otherwise be provided by the Administrator either in
the Award Certificate or, subject to Section 15 below, in writing after the Award is issued, a grantee’s rights in all Dividend Equivalent Rights shall automatically terminate upon the grantee’s termination of employment (or cessation
of Service Relationship) with the Company and its Subsidiaries for any reason. 
 SECTION 12. TRANSFERABILITY OF AWARDS 

(a) Transferability. Except as provided in Section 12(b) below, during a grantee’s lifetime, his or her Awards shall be
exercisable only by the grantee, or by the grantee’s legal representative or guardian in the event of the grantee’s incapacity. No Awards shall be sold, assigned, transferred or otherwise encumbered or disposed of by a grantee other than
by will or by the laws of descent and distribution or pursuant to a domestic relations order. No Awards shall be subject, in whole or in part, to attachment, execution, or levy of any kind, and any purported transfer in violation hereof shall be
null and void. 
 (b) Administrator Action. Notwithstanding Section 12(a), the Administrator, in its discretion, may provide
either in the Award Certificate regarding a given Award or by subsequent written approval that the grantee (who is an employee or director) may transfer his or her Non-Qualified Stock Options to his or her
immediate family members, to trusts for the benefit of such family members, or to partnerships in which such family members are the only partners, provided that the transferee agrees in writing with the Company to be bound by all of the terms and
conditions of this Plan and the applicable Award. In no event may an Award be transferred by a grantee for value. 
 (c) Family
Member. For purposes of Section 12(b), “family member” shall mean a grantee’s child, stepchild, grandchild, parent, stepparent, grandparent, spouse, former spouse, sibling, niece, nephew, mother-in-law, father-in-law, son-in-law, daughter-in-law, brother-in-law, or sister-in-law, including adoptive relationships, any person sharing the grantee’s household (other than a tenant of the grantee), a trust in which these persons (or the grantee) have more than
50 percent of the beneficial interest, a foundation in which these persons (or the grantee) control the management of assets, and any other entity in which these persons (or the grantee) own more than 50 percent of the voting interests.

 (d) Designation of Beneficiary. To the extent permitted by the Company and valid under applicable law, each grantee to whom an
Award has been made under the Plan may designate a beneficiary or beneficiaries to exercise any Award or receive any payment under any Award payable on or after the grantee’s death. Any such designation shall be on a form provided for that
purpose by the Administrator and shall not be effective until received by the Administrator. If no beneficiary has been designated by a deceased grantee, or if the designated beneficiaries have predeceased the grantee, the beneficiary shall be the
grantee’s estate or legal heirs. 

  
 13 

 SECTION 13. TAX WITHHOLDING 

(a) Payment by Grantee. Each grantee shall, no later than the date as of which the value of an Award or of any Stock or other amounts
received thereunder first becomes includable in the gross income of the grantee for tax purposes, pay to the Company or any applicable Affiliate, or make arrangements satisfactory to the Administrator regarding payment of, any U.S. and non-U.S. federal, state, or local taxes of any kind required by law to be withheld by the Company or any applicable Affiliate with respect to such income. The Company and its Affiliates shall, to the extent
permitted by law, have the right to deduct any such taxes from any payment of any kind otherwise due to the grantee or to satisfy any applicable withholding obligations by any other method of withholding that the Company and its Affiliates deem
appropriate. The Company’s obligation to deliver evidence of book entry (or stock certificates) to any grantee is subject to and conditioned on tax withholding obligations being satisfied by the grantee. 

(b) Payment in Stock. The Administrator may cause any tax withholding obligation of the Company or any applicable Affiliate to be
satisfied, in whole or in part, by the Company withholding from shares of Stock to be issued pursuant to any Award a number of shares with an aggregate Fair Market Value (as of the date the withholding is effected) that would satisfy the withholding
amount due; provided, however, that the amount withheld does not exceed the maximum statutory rate or such lesser amount as is necessary to avoid liability accounting treatment. For purposes of share withholding, the Fair Market Value of withheld
shares shall be determined in the same manner as the value of Stock includible in income of the Participants. The Administrator may also require any tax withholding obligation of the Company or any applicable Affiliate to be satisfied, in whole or
in part, by an arrangement whereby a certain number of shares of Stock issued pursuant to any Award are immediately sold and proceeds from such sale are remitted to the Company or any applicable Affiliate in an amount that would satisfy the
withholding amount due. 
 SECTION 14. SECTION 409A AWARDS 

Awards are intended to be exempt from Section 409A to the greatest extent possible and to otherwise comply with Section 409A. The
Plan and all Awards shall be interpreted in accordance with such intent. To the extent that any Award is determined to constitute “nonqualified deferred compensation” within the meaning of Section 409A (a “409A Award”), the
Award shall be subject to such additional rules and requirements as specified by the Administrator from time to time in order to comply with Section 409A. In this regard, if any amount under a 409A Award is payable upon a “separation from
service” (within the meaning of Section 409A) to a grantee who is then considered a “specified employee” (within the meaning of Section 409A), then no such payment shall be made prior to the date that is the earlier of
(i) six months and one day after the grantee’s separation from service, or (ii) the grantee’s death, but only to the extent such delay is necessary to prevent such payment from being subject to interest, penalties and/or
additional tax imposed pursuant to Section 409A. Further, the settlement of any 409A Award may not be accelerated except to the extent permitted by Section 409A. 

SECTION 15. TERMINATION OF SERVICE RELATIONSHIP, TRANSFER, LEAVE OF ABSENCE, ETC. 

(a) Termination of Service Relationship. If the grantee’s Service Relationship is with an Affiliate and such Affiliate
ceases to be an Affiliate, the grantee shall be deemed to have terminated his or her Service Relationship for purposes of the Plan. 

  
 14 

 (b) For purposes of the Plan, the following events shall not be deemed a termination of a
Service Relationship: 
 (i) a transfer to the employment of the Company from an Affiliate or from the Company to an Affiliate, or from one
Affiliate to another; or 
 (ii) an approved leave of absence for military service or sickness, or for any other purpose approved by the
Company, if the employee’s right to re-employment is guaranteed either by a statute or by contract or under the policy pursuant to which the leave of absence was granted or if the Administrator otherwise
so provides in writing. 
 SECTION 16. AMENDMENTS AND TERMINATION 

The Board may, at any time, amend or discontinue the Plan and the Administrator may, at any time, amend or cancel any outstanding Award for the
purpose of satisfying changes in law or for any other lawful purpose, but no such action shall adversely affect rights under any outstanding Award without the holder’s consent. The Administrator is specifically authorized to exercise its
discretion to reduce the exercise price of outstanding Stock Options or Stock Appreciation Rights or effect the repricing of such Awards through cancellation and re-grants. To the extent required under the
rules of any securities exchange or market system on which the Stock is listed, to the extent determined by the Administrator to be required by the Code to ensure that Incentive Stock Options granted under the Plan are qualified under
Section 422 of the Code, Plan amendments shall be subject to approval by Company stockholders. Nothing in this Section 16 shall limit the Administrator’s authority to take any action permitted pursuant to Section 3(c) or 3(d).

 SECTION 17. STATUS OF PLAN 
 With
respect to the portion of any Award that has not been exercised and any payments in cash, Stock or other consideration not received by a grantee, a grantee shall have no rights greater than those of a general creditor of the Company unless the
Administrator shall otherwise expressly determine in connection with any Award or Awards. In its sole discretion, the Administrator may authorize the creation of trusts or other arrangements to meet the Company’s obligations to deliver Stock or
make payments with respect to Awards hereunder, provided that the existence of such trusts or other arrangements is consistent with the foregoing sentence. 

SECTION 18. GENERAL PROVISIONS 
 (a) No
Distribution. The Administrator may require each person acquiring Stock pursuant to an Award to represent to and agree with the Company in writing that such person is acquiring the shares without a view to distribution thereof. 

(b) Issuance of Stock. To the extent certificated, stock certificates to grantees under this Plan shall be deemed delivered for
all purposes when the Company or a stock transfer agent of the Company shall have mailed such certificates in the United States mail, addressed to the grantee, at the grantee’s last known address on file with the Company. Uncertificated Stock
shall be deemed delivered for all purposes when the Company or a Stock transfer agent of the Company shall have given to the grantee by electronic mail (with proof of receipt) or by United 

  
 15 

 
States mail, addressed to the grantee, at the grantee’s last known address on file with the Company, notice of issuance and recorded the issuance in its records (which may include electronic
“book entry” records). Notwithstanding anything herein to the contrary, the Company shall not be required to issue or deliver any evidence of book entry or certificates evidencing shares of Stock pursuant to the exercise or settlement of
any Award, unless and until the Administrator has determined, with advice of counsel (to the extent the Administrator deems such advice necessary or advisable), that the issuance and delivery is in compliance with all applicable laws, regulations of
governmental authorities and, if applicable, the requirements of any exchange on which the shares of Stock are listed, quoted or traded. Any Stock issued pursuant to the Plan shall be subject to any stop-transfer orders and other restrictions as the
Administrator deems necessary or advisable to comply with federal, state or foreign jurisdiction, securities or other laws, rules and quotation system on which the Stock is listed, quoted or traded. The Administrator may place legends on any Stock
certificate or notations on any book entry to reference restrictions applicable to the Stock. In addition to the terms and conditions provided herein, the Administrator may require that an individual make such reasonable covenants, agreements, and
representations as the Administrator, in its discretion, deems necessary or advisable in order to comply with any such laws, regulations, or requirements. The Administrator shall have the right to require any individual to comply with any timing or
other restrictions with respect to the settlement or exercise of any Award, including a window-period limitation, as may be imposed in the discretion of the Administrator. 

(c) Stockholder Rights. Until Stock is deemed delivered in accordance with Section 18(b), no right to vote or receive dividends or
any other rights of a stockholder will exist with respect to shares of Stock to be issued in connection with an Award, notwithstanding the exercise of a Stock Option or any other action by the grantee with respect to an Award. 

(d) Other Incentive Arrangements; No Rights to Continued Service Relationship. Nothing contained in this Plan shall prevent the Board
from adopting other or additional incentive arrangements, including trusts, and such arrangements may be either generally applicable or applicable only in specific cases. The adoption of this Plan and the grant of Awards do not confer upon any
grantee any right to continued employment or other Service Relationship with the Company or any Affiliate. 
 (e) Trading Policy
Restrictions. Option exercises and other Awards under the Plan shall be subject to the Company’s insider trading policies and procedures, as in effect from time to time. 

(f) Clawback Policy. Awards under the Plan shall be subject to the Company’s clawback policy, as in effect from time to time. 

SECTION 19. EFFECTIVE DATE OF PLAN 
 This
Plan shall become effective upon the date immediately preceding the Registration Date subject to prior stockholder approval in accordance with applicable state law, the Company’s bylaws and articles of incorporation, and applicable stock
exchange rules. No grants of Awards may be made hereunder after the tenth anniversary of the Effective Date and no grants of Incentive Stock Options may be made hereunder after the tenth anniversary of the date the Plan is approved by the Board.

  
 16 

 SECTION 20. GOVERNING LAW 

This Plan and all Awards and actions taken thereunder 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 in accordance with the internal laws of the State of California, applied without regard to conflict of law principles.

 Pursuant to the BridgeBio Pharma, Inc. 2019 Stock Option and Incentive Plan as amended through the date hereof
(the “Plan”), BridgeBio Pharma, Inc. (the “Company”) hereby grants to the Optionee named above an option (the “Stock Option”) to purchase on or prior to the Expiration Date specified above all or part of the number of
shares of Common Stock, par value $0.001 per share (the “Stock”), of the Company specified above at the Option Exercise Price per Share specified above subject to the terms and conditions set forth herein and in the Plan. 

1. Exercisability Schedule. No portion of this Stock Option may be exercised until such portion shall have become exercisable. Except as
set forth below, and subject to the discretion of the Administrator (as defined in Section 2 of the Plan) to accelerate the exercisability schedule hereunder, this Stock Option shall be exercisable with respect to the following number of Option
Shares on the dates indicated so long as the Optionee continues to have a Service Relationship with the Company or a Subsidiary on such dates: 
  

			
	 Incremental Number of
Option Shares
Exercisable*
	  	Exercisability Date
	_________ (___%)	  	  

	_________ (___%)	  	  

	_________ (___%)	  	  

	_________ (___%)	  	  

	_________ (___%)	  	  

 Once
exercisable, this Stock Option shall continue to be exercisable at any time or times prior to the close of business on the Expiration Date, subject to the provisions hereof and of the Plan. Further, to the extent this Stock Option and any other
incentive stock options of the Optionee having an aggregate Fair Market Value in excess of $100,000 (determined as of the Grant Date) first become exercisable in any year, such options will not qualify as incentive stock options. 

 2. Manner of Exercise. 

(a) The Optionee may exercise this Stock Option only in the following manner: from time to time on or prior to the Expiration Date of this
Stock Option, the Optionee may give written notice to the Administrator of his or her election to purchase some or all of the Option Shares purchasable at the time of such notice. This notice shall specify the number of Option Shares to be
purchased. 
 Payment of the purchase price for the Option Shares may be made by one or more of the following methods: (i) in cash, by
certified or bank check or other instrument acceptable to the Administrator; (ii) through the delivery (or attestation to the ownership) of shares of Stock that have been purchased by the Optionee on the open market or that are beneficially
owned by the Optionee and are not then subject to any restrictions under any Company plan and that otherwise satisfy any holding periods as may be required by the Administrator; or (iii) by the Optionee delivering to the Company a properly
executed exercise notice together with irrevocable instructions to a broker to promptly deliver to the Company cash or a check payable and acceptable to the Company to pay the option purchase price, provided that in the event the Optionee chooses to
pay the option purchase price as so provided, the Optionee and the broker shall comply with such procedures and enter into such agreements of indemnity and other agreements as the Administrator shall prescribe as a condition of such payment
procedure; or (iv) a combination of (i), (ii) and (iii) above. Payment instruments will be received subject to collection. 
 The
transfer to the Optionee on the records of the Company or of the transfer agent of the Option Shares will be contingent upon (i) the Company’s receipt from the Optionee of the full purchase price for the Option Shares, as set forth above,
(ii) the fulfillment of any other requirements contained herein or in the Plan or in any other agreement or provision of laws, and (iii) the receipt by the Company of any agreement, statement or other evidence that the Company may require
to satisfy itself that the issuance of Stock to be purchased pursuant to the exercise of Stock Options under the Plan and any subsequent resale of the shares of Stock will be in compliance with applicable laws and regulations. In the event the
Optionee chooses to pay the purchase price by previously-owned shares of Stock through the attestation method, the number of shares of Stock transferred to the Optionee upon the exercise of the Stock Option shall be net of the Shares attested to.

 (b) The shares of Stock purchased upon exercise of this Stock Option shall be transferred to the Optionee on the records of the Company or
of the transfer agent upon compliance to the satisfaction of the Administrator with all requirements under applicable laws or regulations in connection with such transfer and with the requirements hereof and of the Plan. The determination of the
Administrator as to such compliance shall be final and binding on the Optionee. The Optionee shall not be deemed to be the holder of, or to have any of the rights of a holder with respect to, any shares of Stock subject to this Stock Option unless
and until this Stock Option shall have been exercised pursuant to the terms hereof, the Company or the transfer agent shall have transferred the shares to the Optionee, and the Optionee’s name shall have been entered as the stockholder of
record on the books of the Company. Thereupon, the Optionee shall have full voting, dividend and other ownership rights with respect to such shares of Stock. 

  
 2 

 (c) The minimum number of shares with respect to which this Stock Option may be exercised at
any one time shall be 100 shares, unless the number of shares with respect to which this Stock Option is being exercised is the total number of shares subject to exercise under this Stock Option at the time. 

(d) Notwithstanding any other provision hereof or of the Plan, no portion of this Stock Option shall be exercisable after the Expiration Date
hereof. 
 3. Termination of Service Relationship. If the Optionee’s Service Relationship with the Company or a Subsidiary (as
defined in the Plan) is terminated, the period within which to exercise the Stock Option may be subject to earlier termination as set forth below. 

(a) Termination Due to Death. If the Optionee’s Service Relationship with the Company or a Subsidiary terminates by reason of the
Optionee’s death, any portion of this Stock Option outstanding on such date, to the extent exercisable on the date of death, may thereafter be exercised by the Optionee’s legal representative or legatee for a period of 12 months from the
date of death or until the Expiration Date, if earlier. Any portion of this Stock Option that is not exercisable on the date of death shall terminate immediately and be of no further force or effect. 

(b) Termination Due to Disability. If the Optionee’s Service Relationship with the Company or a Subsidiary terminates by reason of
the Optionee’s disability (as determined by the Administrator), any portion of this Stock Option outstanding on such date, to the extent exercisable on the date of such termination, may thereafter be exercised by the Optionee for a period of 12
months from the date of disability or until the Expiration Date, if earlier. Any portion of this Stock Option that is not exercisable on the date of disability shall terminate immediately and be of no further force or effect. 

(c) Termination for Cause. If the Optionee’s Service Relationship with the Company or a Subsidiary terminates for Cause, any
portion of this Stock Option outstanding on such date shall terminate immediately and be of no further force and effect. For purposes hereof, “Cause” shall mean, unless otherwise provided in an employment or other service agreement between
the Company and the Optionee, a determination by the Administrator that the Optionee shall be dismissed as a result of (i) any material breach by the Optionee of any agreement between the Optionee and the Company; (ii) the
conviction of, indictment for or plea of nolo contendere by the Optionee to a felony or a crime involving moral turpitude; or (iii) any material misconduct or willful and deliberate non-performance (other
than by reason of disability) by the Optionee of the Optionee’s duties to the Company. 
 (d) Other Termination. If the
Optionee’s Service Relationship with the Company or a Subsidiary terminates for any reason other than the Optionee’s death, the Optionee’s disability, or Cause, and unless otherwise determined by the Administrator, any portion of this
Stock Option outstanding on such date may be exercised, to the extent exercisable on the date of termination, for a period of three months from the date of termination or until the Expiration Date, if earlier. Any portion of this Stock Option that
is not exercisable on the date of termination shall terminate immediately and be of no further force or effect. 

  
 3 

 The Administrator’s determination of the reason for termination of the Optionee’s
Service Relationship with the Company or a Subsidiary shall be conclusive and binding on the Optionee and his or her representatives or legatees. 

4. Incorporation of Plan. Notwithstanding anything herein to the contrary, this Stock Option shall be subject to and governed by all the
terms and conditions of the Plan, including the powers of the Administrator set forth in Section 2(b) of the Plan. Capitalized terms in this Agreement shall have the meaning specified in the Plan, unless a different meaning is specified herein.

 5. Transferability. This Agreement is personal to the Optionee, is non-assignable and is
not transferable in any manner, by operation of law or otherwise, other than by will or the laws of descent and distribution. This Stock Option is exercisable, during the Optionee’s lifetime, only by the Optionee, and thereafter, only by the
Optionee’s legal representative or legatee. 
 6. Status of the Stock Option. This Stock Option is intended to qualify as an
“incentive stock option” under Section 422 of the Internal Revenue Code of 1986, as amended (the “Code”), but the Company does not represent or warrant that this Stock Option qualifies as such. The Optionee should consult
with his or her own tax advisors regarding the tax effects of this Stock Option and the requirements necessary to obtain favorable income tax treatment under Section 422 of the Code, including, but not limited to, holding period requirements.
To the extent any portion of this Stock Option does not so qualify as an “incentive stock option,” such portion shall be deemed to be a non-qualified stock option. If the Optionee intends to dispose
or does dispose (whether by sale, gift, transfer or otherwise) of any Option Shares within the one-year period beginning on the date after the transfer of such shares to him or her, or within the two-year period beginning on the day after the grant of this Stock Option, he or she will so notify the Company within 30 days after such disposition. 

7. Tax Withholding. The Optionee shall, not later than the date as of which the exercise of this Stock Option becomes a taxable event
for Federal income tax purposes, pay to the Company or make arrangements satisfactory to the Administrator for payment of any Federal, state, and local taxes required by law to be withheld on account of such taxable event. The Company shall have the
authority to cause the required tax withholding obligation to be satisfied, in whole or in part, by withholding from shares of Stock to be issued to the Optionee a number of shares of Stock with an aggregate Fair Market Value that would satisfy the
withholding amount due. 
 8. No Obligation to Continue Service Relationship. Neither the Company nor any Subsidiary is obligated by
or as a result of the Plan or this Agreement to continue the Optionee’s Service Relationship with the Company or a Subsidiary and neither the Plan nor this Agreement shall interfere in any way with the right of the Company or any Subsidiary to
terminate the Optionee’s Service Relationship with the Company or a Subsidiary at any time. 
 9. Integration. This Agreement
constitutes the entire agreement between the parties with respect to this Stock Option and supersedes all prior agreements and discussions between the parties concerning such subject matter. 

  
 4 

 10. Data Privacy Consent. In order to administer the Plan and this Agreement and to
implement or structure future equity grants, the Company, its subsidiaries and affiliates and certain agents thereof (together, the “Relevant Companies”) may process any and all personal or professional data, including but not limited to
Social Security or other identification number, home address and telephone number, date of birth and other information that is necessary or desirable for the administration of the Plan and/or this Agreement (the “Relevant Information”). By
entering into this Agreement, the Optionee (i) authorizes the Company to collect, process, register and transfer to the Relevant Companies all Relevant Information; (ii) waives any privacy rights the Optionee may have with respect to the
Relevant Information; (iii) authorizes the Relevant Companies to store and transmit such information in electronic form; and (iv) authorizes the transfer of the Relevant Information to any jurisdiction in which the Relevant Companies
consider appropriate. The Optionee shall have access to, and the right to change, the Relevant Information. Relevant Information will only be used in accordance with applicable law. 

11. Notices. Notices hereunder shall be mailed or delivered to the Company at its principal place of business and shall be mailed or
delivered to the Optionee at the address on file with the Company or, in either case, at such other address as one party may subsequently furnish to the other party in writing.

 Once
exercisable, this Stock Option shall continue to be exercisable at any time or times prior to the close of business on the Expiration Date, subject to the provisions hereof and of the Plan. 

 2. Manner of Exercise. 

(a) The Optionee may exercise this Stock Option only in the following manner: from time to time on or prior to the Expiration Date of this
Stock Option, the Optionee may give written notice to the Administrator of his or her election to purchase some or all of the Option Shares purchasable at the time of such notice. This notice shall specify the number of Option Shares to be
purchased. 
 Payment of the purchase price for the Option Shares may be made by one or more of the following methods: (i) in cash, by
certified or bank check or other instrument acceptable to the Administrator; (ii) through the delivery (or attestation to the ownership) of shares of Stock that have been purchased by the Optionee on the open market or that are beneficially
owned by the Optionee and are not then subject to any restrictions under any Company plan and that otherwise satisfy any holding periods as may be required by the Administrator; (iii) by the Optionee delivering to the Company a properly
executed exercise notice together with irrevocable instructions to a broker to promptly deliver to the Company cash or a check payable and acceptable to the Company to pay the option purchase price, provided that in the event the Optionee chooses to
pay the option purchase price as so provided, the Optionee and the broker shall comply with such procedures and enter into such agreements of indemnity and other agreements as the Administrator shall prescribe as a condition of such payment
procedure; (iv) by a “net exercise” arrangement pursuant to which the Company will reduce the number of shares of Stock issuable upon exercise by the largest whole number of shares with a Fair Market Value that does not exceed the
aggregate exercise price; or (v) a combination of (i), (ii), (iii) and (iv) above. Payment instruments will be received subject to collection. 

The transfer to the Optionee on the records of the Company or of the transfer agent of the Option Shares will be contingent upon (i) the
Company’s receipt from the Optionee of the full purchase price for the Option Shares, as set forth above, (ii) the fulfillment of any other requirements contained herein or in the Plan or in any other agreement or provision of laws, and
(iii) the receipt by the Company of any agreement, statement or other evidence that the Company may require to satisfy itself that the issuance of Stock to be purchased pursuant to the exercise of Stock Options under the Plan and any subsequent
resale of the shares of Stock will be in compliance with applicable laws and regulations. In the event the Optionee chooses to pay the purchase price by previously-owned shares of Stock through the attestation method, the number of shares of Stock
transferred to the Optionee upon the exercise of the Stock Option shall be net of the Shares attested to. 
 (b) The shares of Stock
purchased upon exercise of this Stock Option shall be transferred to the Optionee on the records of the Company or of the transfer agent upon compliance to the satisfaction of the Administrator with all requirements under applicable laws or
regulations in connection with such transfer and with the requirements hereof and of the Plan. The determination of the Administrator as to such compliance shall be final and binding on the Optionee. The Optionee shall not be deemed to be the holder
of, or to have any of the rights of a holder with respect to, any shares of Stock subject to this Stock Option unless and until this Stock Option shall have been exercised pursuant to the terms hereof, the Company or the transfer agent shall have
transferred the shares to the Optionee, and the Optionee’s name shall have been entered as the stockholder of record on the books of the Company. Thereupon, the Optionee shall have full voting, dividend and other ownership rights with respect
to such shares of Stock. 

  
 2 

 (c) The minimum number of shares with respect to which this Stock Option may be exercised at
any one time shall be 100 shares, unless the number of shares with respect to which this Stock Option is being exercised is the total number of shares subject to exercise under this Stock Option at the time. 

(d) Notwithstanding any other provision hereof or of the Plan, no portion of this Stock Option shall be exercisable after the Expiration Date
hereof. 
 3. Termination of Service Relationship. If the Optionee’s Service Relationship with the Company or a Subsidiary (as
defined in the Plan) is terminated, the period within which to exercise the Stock Option may be subject to earlier termination as set forth below. 

(a) Termination Due to Death. If the Optionee’s Service Relationship with the Company or a Subsidiary terminates by reason of the
Optionee’s death, any portion of this Stock Option outstanding on such date, to the extent exercisable on the date of death, may thereafter be exercised by the Optionee’s legal representative or legatee for a period of 12 months from the
date of death or until the Expiration Date, if earlier. Any portion of this Stock Option that is not exercisable on the date of death shall terminate immediately and be of no further force or effect. 

(b) Termination Due to Disability. If the Optionee’s Service Relationship with the Company or a Subsidiary terminates by reason of
the Optionee’s disability (as determined by the Administrator), any portion of this Stock Option outstanding on such date, to the extent exercisable on the date of such termination, may thereafter be exercised by the Optionee for a period of 12
months from the date of disability or until the Expiration Date, if earlier. Any portion of this Stock Option that is not exercisable on the date of disability shall terminate immediately and be of no further force or effect. 

(c) Termination for Cause. If the Optionee’s Service Relationship with the Company or a Subsidiary terminates for Cause, any
portion of this Stock Option outstanding on such date shall terminate immediately and be of no further force and effect. For purposes hereof, “Cause” shall mean, unless otherwise provided in an employment or other service agreement between
the Company and the Optionee, a determination by the Administrator that the Optionee shall be dismissed as a result of (i) any material breach by the Optionee of any agreement between the Optionee and the Company; (ii) the conviction of,
indictment for or plea of nolo contendere by the Optionee to a felony or a crime involving moral turpitude; or (iii) any material misconduct or willful and deliberate non-performance (other than by reason
of disability) by the Optionee of the Optionee’s duties to the Company. 
 (d) Other Termination. If the Optionee’s Service
Relationship with the Company or a Subsidiary terminates for any reason other than the Optionee’s death, the Optionee’s disability or Cause, and unless otherwise determined by the Administrator, any portion of this Stock Option outstanding
on such date may be exercised, to the extent exercisable on the date of termination, for a period of three months from the date of termination or until the Expiration Date, if earlier. Any portion of this Stock Option that is not exercisable on the
date of termination shall terminate immediately and be of no further force or effect. 

  
 3 

 The Administrator’s determination of the reason for termination of the Optionee’s
Service Relationship with the Company or a Subsidiary shall be conclusive and binding on the Optionee and his or her representatives or legatees. 

4. Incorporation of Plan. Notwithstanding anything herein to the contrary, this Stock Option shall be subject to and governed by all the
terms and conditions of the Plan, including the powers of the Administrator set forth in Section 2(b) of the Plan. Capitalized terms in this Agreement shall have the meaning specified in the Plan, unless a different meaning is specified herein.

 5. Transferability. This Agreement is personal to the Optionee, is non-assignable and is
not transferable in any manner, by operation of law or otherwise, other than by will or the laws of descent and distribution. This Stock Option is exercisable, during the Optionee’s lifetime, only by the Optionee, and thereafter, only by the
Optionee’s legal representative or legatee. 
 6. Tax Withholding. The Optionee shall, not later than the date as of which the
exercise of this Stock Option becomes a taxable event for Federal income tax purposes, pay to the Company or make arrangements satisfactory to the Administrator for payment of any Federal, state, and local taxes required by law to be withheld on
account of such taxable event. The Company shall have the authority to cause the required tax withholding obligation to be satisfied, in whole or in part, by withholding from shares of Stock to be issued to the Optionee a number of shares of Stock
with an aggregate Fair Market Value that would satisfy the withholding amount due. 
 7. No Obligation to Continue Service
Relationship. Neither the Company nor any Subsidiary is obligated by or as a result of the Plan or this Agreement to continue the Optionee in a Service Relationship with the Company or a Subsidiary and neither the Plan nor this Agreement shall
interfere in any way with the right of the Company or any Subsidiary to terminate the Optionee’s Service Relationship with the Company or a Subsidiary at any time. 

8. Integration. This Agreement constitutes the entire agreement between the parties with respect to this Stock Option and supersedes all
prior agreements and discussions between the parties concerning such subject matter. 
 9. Data Privacy Consent. In order to
administer the Plan and this Agreement and to implement or structure future equity grants, the Company, its subsidiaries and affiliates and certain agents thereof (together, the “Relevant Companies”) may process any and all personal or
professional data, including but not limited to Social Security or other identification number, home address and telephone number, date of birth and other information that is necessary or desirable for the administration of the Plan and/or this
Agreement (the “Relevant Information”). By entering into this Agreement, the Optionee (i) authorizes the Company to collect, process, register and transfer to the Relevant Companies all Relevant Information; (ii) waives any
privacy rights the Optionee may have with respect to the Relevant Information; (iii) authorizes the 

  
 4 

 
Relevant Companies to store and transmit such information in electronic form; and (iv) authorizes the transfer of the Relevant Information to any jurisdiction in which the Relevant Companies

 Pursuant to the BridgeBio Pharma, Inc. 2019 Stock Option and Incentive Plan as amended through the date hereof
(the “Plan”), BridgeBio Pharma, Inc. (the “Company”) hereby grants to the Optionee named above, who is a Director of the Company but is not an employee of the Company, an option (the “Stock Option”) to purchase on or
prior to the Expiration Date specified above all or part of the number of shares of Common Stock, par value $0.001 per share (the “Stock”), of the Company specified above at the Option Exercise Price per Share specified above subject to
the terms and conditions set forth herein and in the Plan. This Stock Option is not intended to be an “incentive stock option” under Section 422 of the Internal Revenue Code of 1986, as amended. 

1. Exercisability Schedule. No portion of this Stock Option may be exercised until such portion shall have become exercisable. Except
as set forth below, and subject to the discretion of the Administrator (as defined in Section 2 of the Plan) to accelerate the exercisability schedule hereunder, this Stock Option shall be exercisable with respect to the following number of
Option Shares on the dates indicated so long as the Optionee continues to have a Service Relationship with the Company or a Subsidiary on such dates: 
  

			
	 Incremental Number of
Option Shares
Exercisable
	  	Exercisability Date
	__________ (___%)	  	  

	__________ (___%)	  	  

	__________ (___%)	  	  

	__________ (___%)	  	  

	__________ (___%)	  	  

 [Notwithstanding the foregoing, in the event of a Sale Event, 100% of the then-outstanding
and unvested Option Shares shall immediately be deemed vested and exercisable on the date of such Sale Event]; provided, that the Optionee continues to have a Service Relationship with the Company or a Subsidiary until the date of such Sale Event.
Once exercisable, this Stock Option shall continue to be exercisable at any time or times prior to the close of business on the Expiration Date, subject to the provisions hereof and of the Plan. 

2. Manner of Exercise. 

(a) The Optionee may exercise this Stock Option only in the following manner: from time to time on or prior to the Expiration Date of this
Stock Option, the Optionee may give written notice to the Administrator of his or her election to purchase some or all of the Option Shares purchasable at the time of such notice. This notice shall specify the number of Option Shares to be
purchased. 
 Payment of the purchase price for the Option Shares may be made by one or more of the following methods: (i) in cash, by
certified or bank check or other instrument acceptable to the Administrator; (ii) through the delivery (or attestation to the ownership) of shares of Stock that have been purchased by the Optionee on the open market or that are beneficially
owned by the Optionee and are not then subject to any restrictions under any Company plan and that otherwise satisfy any holding periods as may be required by the Administrator; (iii) by the Optionee delivering to the Company a properly
executed exercise notice together with irrevocable instructions to a broker to promptly deliver to the Company cash or a check payable and acceptable to the Company to pay the option purchase price, provided that in the event the Optionee chooses to
pay the option purchase price as so provided, the Optionee and the broker shall comply with such procedures and enter into such agreements of indemnity and other agreements as the Administrator shall prescribe as a condition of such payment
procedure; (iv) by a “net exercise” arrangement pursuant to which the Company will reduce the number of shares of Stock issuable upon exercise by the largest whole number of shares with a Fair Market Value that does not exceed the
aggregate exercise price; or (v) a combination of (i), (ii), (iii) and (iv) above. Payment instruments will be received subject to collection. 

The transfer to the Optionee on the records of the Company or of the transfer agent of the Option Shares will be contingent upon (i) the
Company’s receipt from the Optionee of the full purchase price for the Option Shares, as set forth above, (ii) the fulfillment of any other requirements contained herein or in the Plan or in any other agreement or provision of laws, and
(iii) the receipt by the Company of any agreement, statement or other evidence that the Company may require to satisfy itself that the issuance of Stock to be purchased pursuant to the exercise of Stock Options under the Plan and any subsequent
resale of the shares of Stock will be in compliance with applicable laws and regulations. In the event the Optionee chooses to pay the purchase price by previously-owned shares of Stock through the attestation method, the number of shares of Stock
transferred to the Optionee upon the exercise of the Stock Option shall be net of the Shares attested to. 

  
 2 

 (b) The shares of Stock purchased upon exercise of this Stock Option shall be transferred to
the Optionee on the records of the Company or of the transfer agent upon compliance to the satisfaction of the Administrator with all requirements under applicable laws or regulations in connection with such transfer and with the requirements hereof
and of the Plan. The determination of the Administrator as to such compliance shall be final and binding on the Optionee. The Optionee shall not be deemed to be the holder of, or to have any of the rights of a holder with respect to, any shares of
Stock subject to this Stock Option unless and until this Stock Option shall have been exercised pursuant to the terms hereof, the Company or the transfer agent shall have transferred the shares to the Optionee, and the Optionee’s name shall
have been entered as the stockholder of record on the books of the Company. Thereupon, the Optionee shall have full voting, dividend and other ownership rights with respect to such shares of Stock. 

(c) The minimum number of shares with respect to which this Stock Option may be exercised at any one time shall be 100 shares, unless the
number of shares with respect to which this Stock Option is being exercised is the total number of shares subject to exercise under this Stock Option at the time. 

(d) Notwithstanding any other provision hereof or of the Plan, no portion of this Stock Option shall be exercisable after the Expiration Date
hereof. 
 3. Termination of Service Relationship. If the Optionee’s Service Relationship with the Company or a Subsidiary
ceases, the period within which to exercise the Stock Option may be subject to earlier termination as set forth below. 
 (a) Termination
Due to Death. If the Optionee’s Service Relationship with the Company or a Subsidiary terminates by reason of the Optionee’s death, any portion of this Stock Option outstanding on such date, to the extent exercisable on the date of
death, may thereafter be exercised by the Optionee’s legal representative or legatee for a period of 12 months from the date of death or until the Expiration Date, if earlier. Any portion of this Stock Option that is not exercisable on the date
of death shall terminate immediately and be of no further force or effect. 
 (b) Other Termination. If the Optionee’s Service
Relationship with the Company or a Subsidiary ceases for any reason other than the Optionee’s death, any portion of this Stock Option outstanding on such date may be exercised, to the extent exercisable on the date the Optionee ceased to have a
Service Relationship with the Company or a Subsidiary, for a period of six months from the date the Optionee ceased to have a Service Relationship with the Company or a Subsidiary or until the Expiration Date, if earlier. Any portion of this Stock
Option that is not exercisable on the date the Optionee ceases to have a Service Relationship with the Company or a Subsidiary shall terminate immediately and be of no further force or effect. 

4. Incorporation of Plan. Notwithstanding anything herein to the contrary, this Stock Option shall be subject to and governed by all the
terms and conditions of the Plan, including the powers of the Administrator set forth in Section 2(b) of the Plan. Capitalized terms in this Agreement shall have the meaning specified in the Plan, unless a different meaning is specified herein.

 5. Transferability. This Agreement is personal to the Optionee, is non-assignable and is
not transferable in any manner, by operation of law or otherwise, other than by will or the laws of descent and distribution. This Stock Option is exercisable, during the Optionee’s lifetime, only by the Optionee, and thereafter, only by the
Optionee’s legal representative or legatee. 

  
 3 

 6. No Obligation to Continue Service Relationship. Neither the Plan nor this Stock
Option confers upon the Optionee any rights with respect to continuance of a Service Relationship with the Company or a Subsidiary. 
 7.
Integration. This Agreement constitutes the entire agreement between the parties with respect to this Stock Option and supersedes all prior agreements and discussions between the parties concerning such subject matter. 

8. Data Privacy Consent. In order to administer the Plan and this Agreement and to implement or structure future equity grants, the
Company, its subsidiaries and affiliates and certain agents thereof (together, the “Relevant Companies”) may process any and all personal or professional data, including but not limited to Social Security or other identification number,
home address and telephone number, date of birth and other information that is necessary or desirable for the administration of the Plan and/or this Agreement (the “Relevant Information”). By entering into this Agreement, the Optionee
(i) authorizes the Company to collect, process, register and transfer to the Relevant Companies all Relevant Information; (ii) waives any privacy rights the Optionee may have with respect to the Relevant Information; (iii) authorizes
the Relevant Companies to store and transmit such information in electronic form; and (iv) authorizes the transfer of the Relevant Information to any jurisdiction in which the Relevant Companies consider appropriate. The Optionee shall have
access to, and the right to change, the Relevant Information. Relevant Information will only be used in accordance with applicable law.

is not intended to be an “incentive stock option” under Section 422 of the Internal Revenue Code of 1986, as amended. 
 1.
Exercisability Schedule. No portion of this Stock Option may be exercised until such portion shall have become exercisable. Except as set forth below, and subject to the discretion of the Administrator (as defined in Section 2 of the

[_______________________________________], so long as Optionee continues to have a Service Relationship with the Company or a Subsidiary on
such dates. 
 Once exercisable, this Stock Option shall continue to be exercisable at any time or times prior to the close of business on
the Expiration Date, subject to the provisions hereof and of the Plan. 
 2. Manner of Exercise. 

(a) The Optionee may exercise this Stock Option only in the following manner: from time to time on or prior to the Expiration Date of this

 Payment of the purchase price for the Option Shares may be made by one or more of the
following methods: (i) in cash, by certified or bank check or other instrument acceptable to the Administrator; (ii) through the delivery (or attestation to the ownership) of shares of Stock that have been purchased by the Optionee on the

a condition of such payment procedure; (iv) by a “net exercise” arrangement pursuant to which the Company will reduce the number of shares of Stock issuable upon exercise by the largest whole number of shares with a Fair Market Value
that does not exceed the aggregate exercise price; or (v) a combination of (i), (ii), (iii) and (iv) above. Payment instruments will be received subject to collection.

Option shall be exercisable after the Expiration Date hereof. 
 3. Termination of Service Relationship. Except as may otherwise be
provided by the Administrator, if the Optionee’s Service Relationship with the Company or a Subsidiary (as defined in the Plan) is terminated, the period within which to exercise the Stock Option may be subject to earlier termination as set

months from the date of disability or until the Expiration Date, if earlier. Any portion of this Stock Option that is not exercisable on the date of disability shall terminate immediately and be of no further force or effect. 

(c) Termination for Cause. If the Optionee’s Service Relationship with the Company or a Subsidiary terminates for Cause, any
portion of this Stock Option outstanding on such date shall terminate immediately and be of no further force and effect. For purposes hereof, “Cause” shall mean, unless otherwise provided in a consulting or other service agreement between

 (d) Other Termination. If the Optionee’s Service
Relationship with the Company or a Subsidiary terminates for any reason other than the Optionee’s death, the Optionee’s disability or Cause, and unless otherwise determined by the Administrator, any portion of this Stock Option outstanding
on such date may be exercised, to the extent exercisable on the date of termination, for a period of three months from the date of termination or until the Expiration Date, if earlier. Any portion of this Stock Option that is not exercisable on the
date of termination shall terminate immediately and be of no further force or effect.

 6. No Obligation to Continue Service Relationship. Neither the Company nor any
Subsidiary is obligated by or as a result of the Plan or this Agreement to continue the Optionee’s Service Relationship with the Company or a Subsidiary and neither the Plan nor this Agreement shall interfere in any way with the right of the

 Pursuant to the BridgeBio Pharma, Inc. 2019 Stock Option and Incentive Plan as amended through the date hereof
(the “Plan”), BridgeBio Pharma, Inc. (the “Company”) hereby grants an award of the number of Restricted Stock Units listed above (an “Award”) to the Grantee named above. Each Restricted Stock Unit shall relate to one
share of Common Stock, par value $0.001 per share (the “Stock”) of the Company. 
 1. Restrictions on Transfer of Award.
This Award may not be sold, transferred, pledged, assigned or otherwise encumbered or disposed of by the Grantee, and any shares of Stock issuable with respect to the Award may not be sold, transferred, pledged, assigned or otherwise encumbered or
disposed of until (i) the Restricted Stock Units have vested as provided in Paragraph 2 of this Agreement and (ii) shares of Stock have been issued to the Grantee in accordance with the terms of the Plan and this Agreement. 

2. Vesting of Restricted Stock Units. The restrictions and conditions of Paragraph 1 of this Agreement shall lapse on the Vesting
Date or Dates specified in the following schedule so long as the Grantee continues to have a Service Relationship with the Company or a Subsidiary on such Dates. If a series of Vesting Dates is
specified, then the restrictions and conditions in Paragraph 1 shall lapse only with respect to the number of Restricted Stock Units specified as vested on such date.

	___________ (___%)	  	  

	___________ (___%)	  	  

	___________ (___%)	  	  

 The
Administrator may at any time accelerate the vesting schedule specified in this Paragraph 2. 
 3. Termination of Service
Relationship. If the Grantee’s Service Relationship with the Company or a Subsidiary terminates for any reason (including death or disability) prior to the satisfaction of the vesting conditions set forth in Paragraph 2 above, any
Restricted Stock Units that have not vested as of such date shall automatically and without notice terminate and be forfeited, and neither the Grantee nor any of his or her successors, heirs, assigns, or personal representatives will thereafter have
any further rights or interests in such unvested Restricted Stock Units. 

 4. Issuance of Shares of Stock. As soon as practicable following each Vesting Date
(but in no event later than two and one-half months after the end of the year in which the Vesting Date occurs), the Company shall issue to the Grantee the number of shares of Stock equal to the aggregate
number of Restricted Stock Units that have vested pursuant to Paragraph 2 of this Agreement on such date and the Grantee shall thereafter have all the rights of a stockholder of the Company with respect to such shares. 

5. Incorporation of Plan. Notwithstanding anything herein to the contrary, this Agreement shall be subject to and governed by all the
terms and conditions of the Plan, including the powers of the Administrator set forth in Section 2(b) of the Plan. Capitalized terms in this Agreement shall have the meaning specified in the Plan, unless a different meaning is specified herein.

Federal income tax purposes, pay to the Company or make arrangements satisfactory to the Administrator for payment of any Federal, state, and local taxes required by law to be withheld on account of such taxable event. The Company shall have the
authority to cause the required tax withholding obligation to be satisfied, in whole or in part, by withholding from shares of Stock to be issued to the Grantee a number of shares of Stock with an aggregate Fair Market Value that would satisfy the
withholding amount due. 
 7. Section 409A of the Code. This Agreement shall be interpreted in such a manner that all provisions
relating to the settlement of the Award are exempt from the requirements of Section 409A of the Code as “short-term deferrals” as described in Section 409A of the Code. 

8. No Obligation to Continue Service Relationship. Neither the Company nor any Subsidiary is obligated by or as a result of the Plan or
this Agreement to continue the Grantee’s Service Relationship with the Company or a Subsidiary and neither the Plan nor this Agreement shall interfere in any way with the right of the Company or any Subsidiary to terminate the Grantee’s
Service Relationship with the Company or a Subsidiary at any time. 
 9. Integration. This Agreement constitutes the entire agreement
between the parties with respect to this Award and supersedes all prior agreements and discussions between the parties concerning such subject matter. 

10. Data Privacy Consent. In order to administer the Plan and this Agreement and to implement or structure future equity grants, the
Company, its subsidiaries and affiliates and certain agents thereof (together, the “Relevant Companies”) may process any and all personal or professional data, including but not limited to Social Security or other identification number,
