have such powers, duties, responsibilities and accountabilities as set forth in the Job Description for the Position, or as may from time to time be prescribed by the senior executives or the Board of Directors of the Company (the
“Board”), provided that such duties are consistent with your Position. During your employment with the Company, you will not engage in any other outside employment, consulting or other business activity whether full-time or part-time
without the Company’s written consent, which shall not be unreasonably withheld. By signing this letter agreement, you confirm to the Company that you have no contractual commitments or other legal obligations that would prohibit you from
performing your duties for the Company. 
 2. Salary. The Company will pay you a starting salary beginning as of December 1, 2017 at the annual
rate of $450,000.00, payable in accordance with the Company’s standard payroll schedule and subject to tax-related deductions and withholdings. This salary will be subject to adjustment pursuant to the
Company’s employee compensation policies in effect from time to time. 
 3. Bonus. Compensation for this position also includes participation in
the Company’s bonus plan, which is discretionary and has an annual target bonus of 40% of your annual salary. For each year during the term of this letter agreement, you will be eligible to receive a bonus
(pro-rated in the case of any partial year during which you were employed by the Company) based on a determination by the Company’s Board (or a committee thereof) regarding the Company’s achievement
of its goals and your own successful performance of your duties through the end of the applicable year. 
 4. Employee Benefits. You will be eligible
to participate in or receive benefits under the Company’s employee benefit plans in effect from time to time (including, without limitation, any group health care plan when established), subject to the terms of such plans. 

5. Management Incentive Units. Your equity in the parent holding company, BridgeBio Pharma LLC, is specified in the LLC agreement. 

6. Severance. In the event you are terminated by the Company without Cause or if you resign for Good Reason, subject to you signing a general release of
claims in favor of the Company that becomes irrevocable within sixty (60) days following the termination date, the Company also agrees to pay you a lump sum equal to twelve (12) months of your then-base salary, a pro-rated bonus in accordance with Section 3 above, and twelve (12) months of COBRA reimbursement for you and your dependents if you were participating in the Company’s group health plan immediately
prior to the termination date and elect COBRA health continuation (the “Severance”). If the 60-day period following the termination date begins in one calendar year and ends in a second calendar
year, the Severance shall be paid in the second calendar year and no later than the last day of such 60-day period. Furthermore, to the extent you become eligible for health benefits under a subsequent
employer’s health plan within three (3) months of your termination date, you agree to return a pro-rated amount of the COBRA reimbursement to the Company within sixty (60) days from when you
first become eligible to participate in the subsequent employer’s health plan. 
 7. Employee Confidentiality and Assignment Agreement. Like all
Company employees, you will be required, as a condition of your employment with the Company, to sign the Company’s standard Proprietary Information and Inventions Agreement, a copy of which is attached hereto as Exhibit A. 

 8. Employment Relationship. Employment with the Company is for no specific period of time. Your
employment with the Company will be “at will,” meaning that either you or the Company may terminate your employment at any time and for any reason, with or without cause. Any contrary representations that may have been made to you are
superseded by this letter agreement. Although your job duties, title, reporting relationship, compensation and benefits, as well as the Company’s personnel policies and procedures, may change from time to time (except as otherwise provided
herein), the “at will” nature of your employment may only be changed in an express written agreement signed by you and a duly authorized officer of the Company (other than you). 

9. Interpretation, Amendment and Enforcement. This letter agreement and Exhibit A constitute the complete agreement between you and the Company, contain
all of the terms of your employment with the Company and supersede any prior agreements, representations or understandings (whether written, oral or implied) between you and the Company. This letter agreement may not be amended or modified, except
by an express written agreement signed by both you and a duly authorized officer of the Company. In the event the terms of this letter contradict or are in any way different from the terms contained any other document(s) provided by the Company,
this letter shall control. The terms of this letter agreement and the resolution of any disputes as to the meaning, effect, performance or validity of this letter agreement or arising out of, related to, or in any way connected with, this letter
agreement, your employment with the Company or any other relationship between you and the Company will be governed by California law, excluding laws relating to conflicts or choice of law. 

We hope that you will accept our offer to join the Company. You may indicate your agreement with these terms and accept this offer by signing

	 	•	 	 Enhance and/or develop, implement and enforce policies and procedures of the organization by way of systems that

	 	•	 	 Provide technical financial advice and knowledge to others within the financial discipline.

  

	 	•	 	 Continual improvement of the budgeting process through education of department managers on financial issues
impacting department budgets. 

  

	 	•	 	 Provide strategic financial input and leadership on decision making issues affecting the organization; i.e.,

	 	•	 	 Develop a reliable cash flow projection process and reporting mechanism that includes minimum cash threshold to

	 	•	 	 Evaluate the finance division structure and team plan for continual improvement of the efficiency and

The position is a full-time, exempt position and you will be required to devote 100% of your full working time and efforts to the business and affairs of the
Company. During your employment with the Company, you will not engage in any other outside employment, consulting or other business activity (whether full-time or part-time) without the Company’s written consent, which shall not be unreasonably
withheld. By signing this letter agreement, you confirm to the Company that you have no contractual commitments or other legal obligations that would prohibit you from performing your duties for the Company. 

The Company will pay you a starting base salary beginning as of your start date at the annual rate of $420,000.00, payable in accordance with the
Company’s standard payroll schedule and subject to tax-related deductions and withholdings. This salary will be subject to adjustment pursuant to the Company’s employee compensation policies in
effect from time to time. 

  
 421 Kipling Street, Palo
Alto, CA 94301 

 

 
  

 Compensation for this position also includes participation in the Company’s bonus plan with an annual
target bonus of 45% of your base annual salary. Your bonus will be based on accomplishing the Company’s overall goals as well as your individual goals. For each year during the term of this letter agreement, you will be eligible to receive a
bonus (pro-rated in the case of any partial year during which you were employed by the Company) based on a determination by the Company’s Board (or a committee thereof) regarding the Company’s
achievement of its goals and your own successful performance of your duties through the end of the applicable year. 
 You will be eligible to participate
in or receive benefits under the Company’s employee benefit plans in effect from time to time (including, without limitation, any group health care plan and 401(k)), subject to the terms of such plans. 

Additionally, the Company will pay you a one-time sign-on bonus of $300,000.00
subject to all taxes and withholdings payable in the five (5) business days following your start date of employment. Should you voluntarily terminate with or without cause from the company within the first year of your start date, the sign-on bonus is recoverable and must be paid back in full to the Company. 
 Additionally, subject to the approval of the
Board of Managers of BridgeBio Pharma, LLC (“Parent”), Parent will grant you 1,750,000 management incentive units in Parent (“MIUs”). Parent management incentive units are intended to constitute “profits interests” in
Holdings, as that term is defined in Revenue Procedure 93-27, 1993-2 C.B. 343, as clarified by Revenue Procedure 2001-43, 2001-2 C.B. 191 and, as such, will have a participation threshold equal to the liquidation value of Parent as of the date of grant. Date of grant will occur as soon as practicable after commencement of employment.
Initially, one hundred percent (100%) of the MIUs will be subject to a risk of forfeiture in the event your employment with the Company terminates. The MIUs shall commence vesting on the date of grant (the Vesting Start Date) and will vest at a rate
of 1/60 per month on each monthly anniversary of the Vesting Start Date, so that 100% of such MIUs shall be vested on the fifth anniversary of the [date of grant], subject to your continued employment with the Company through the applicable vesting
date. 
 It is understood that you are an “at-will” employee. You are not being offered employment for a
definite period of time, and either you or the Company may terminate the employment relationship at any time and for any reason, with or without cause or prior notice and without additional compensation to you. Any contrary representations that may
have been made to you are superseded by this letter agreement. Although your job duties, title, reporting relationship, compensation and benefits, as well as the Company’s personnel policies and procedures, may change from time to time (except
as otherwise provided herein), the “at will” nature of your employment may only be changed in an express written agreement signed by you and a duly authorized officer of the Company (other than you). 

Like all Company employees, you will be required, as a condition of your employment with the Company, to sign the Company’s standard Proprietary
Information and Inventions Agreement (the “Confidentiality Agreement”), a copy of which is attached hereto as Exhibit A. 
 This offer is
contingent upon a background check clearance, reference check, and satisfactory proof of your right to work in the United States. You agree to assist as needed and to complete any documentation at the Company’s request to meet these conditions.

 The Immigration Reform and Control Act requires employers to verify the employment eligibility and identity of new employees. You will be required to
complete a Form 1-9 which will be provided to you before your start date. Please bring the appropriate documents listed on that form with you when you report for work. We will not be able to employ you if you
fail to comply with this requirement. Also, this offer is subject to satisfactory reference checks if necessary. 
 This letter agreement and the
Confidentiality Agreement constitute the complete agreement between you and the Company, contain all of the terms of your employment with the Company and supersede any prior agreements, representations or understandings (whether written, oral or
implied) between you and the Company. This letter agreement may not be amended or modified, except by an express written agreement signed by both you and a duly authorized officer of the Company, although your job duties, title, reporting
relationship, compensation and benefits may change from time to time. 

  
 421 Kipling Street, Palo
Alto, CA 94301 

 

 
  

 We hope that you will accept our offer to join the Company. You may indicate your agreement with these terms
and accept this offer by signing and dating both the enclosed duplicate original of this letter agreement and the enclosed Confidentiality Agreement and returning them to me. This offer, if not accepted, will expire at the close of business on
Monday, October 29, 2018. Should you accept this offer, your start date of employment will be October 29, 2018 or any other date agreed upon between you and the Company.
