 Section 1. INTRODUCTION. 

The Reneo Pharmaceuticals, Inc. Severance Benefit Plan (the “Plan”) is hereby established effective as of
January 31, 2018 (the “Effective Date”). The purpose of the Plan is to provide for the payment of severance benefits to eligible key employees of Reneo Pharmaceuticals, Inc. (the
“Company”) in the event that such individuals become subject to involuntary or constructive employment terminations. Except as otherwise provided in an individual Participation Agreement, this Plan shall supersede any
severance benefit plan, policy or practice previously maintained by the Company, including any severance benefits set forth in any individually negotiated employment letter or agreement between the Company and an individual employee or other service
provider. This Plan document also is the Summary Plan Description for the Plan. 
 For purposes of the Plan, the following terms are defined
as follows: 
 (a) “Affiliate” means any corporation (other than the Company) in an “unbroken chain of
corporations” beginning with the Company, if each of the corporations other then the last corporation in the unbroken chain owns stock possessing fifty percent (50%) or more of the total combined voting power of all classes of stock in one of
the other corporations in such chain. 
 (b) “Base Salary” means base pay (excluding incentive pay, premium
pay, commissions, overtime, bonuses and other forms of variable compensation) as in effect prior to any reduction that would give rise to an employee’s right to resign for Good Reason. 

(c) “Board” means the Board of Directors of the Company; provided, however, that if the Board has delegated
authority to administer the Plan to the Compensation Committee of the Board, then “Board” shall also mean the Compensation Committee. 

(d) “Cause” means, with respect to a particular employee, the meaning ascribed to such term in any written
agreement between such employee and the Company defining such term, and, in the absence of such agreement, means with respect to such employee, the occurrence of any of the following events: (i) such employee’s commission of any felony or
any crime involving fraud, dishonesty or moral turpitude under the laws of the United States or any state thereof; (ii) such employee’s attempted commission of, or participation in, a fraud or act of dishonesty against the Company;
(iii) such employee’s intentional, material violation of any contract or agreement between the employee and the Company or of any statutory duty owed to the Company; (iv) such employee’s unauthorized use or disclosure of the
Company’s confidential information or trade secrets; or (v) such employee’s gross misconduct. The determination whether a termination is for Cause shall be made by the Plan Administrator in its sole and exclusive judgment and
discretion. 
 (e) “Change in Control” means the occurrence, in a single transaction or in a series of
related transactions, of any one or more of the following events that also qualifies as a change in the ownership of the Company, a change in the effective control of the Company, or a change in the ownership of a substantial portion of the assets
of the Company (as these events are defined in Treasury Regulations Section § 1.409A-3(i)(5), or as these definitions may later be modified by other regulatory pronouncements): 

  
 1. 













 (1) any Exchange Act Person becomes the Owner, directly or indirectly, of securities
of the Company representing more than fifty percent (50%) of the combined voting power of the Company’s then outstanding securities other than by virtue of a merger, consolidation or similar transaction. Notwithstanding the foregoing,
a Change in Control will not be deemed to occur (A) on account of the acquisition of securities of the Company directly from the Company, (B) on account of the acquisition of securities of the Company by an investor, any affiliate thereof
or any other Exchange Act Person that acquires the Company’s securities in a transaction or series of related transactions the primary purpose of which is to obtain financing for the Company through the issuance of equity securities or
(C) solely because the level of Ownership held by any Exchange Act Person (the “Subject Person”) exceeds the designated percentage threshold of the outstanding voting securities as a
result of a repurchase or other acquisition of voting securities by the Company reducing the number of shares outstanding, provided that if a Change in Control would occur (but for the operation of this sentence) as a result of the acquisition of
voting securities by the Company, and after such share acquisition, the Subject Person becomes the Owner of any additional voting securities that, assuming the repurchase or other acquisition had not occurred, increases the percentage of the then
outstanding voting securities Owned by the Subject Person over the designated percentage threshold, then a Change in Control will be deemed to occur;  

(2) there is consummated a merger, consolidation or similar transaction involving (directly or indirectly) the Company and,
immediately after the consummation of such merger, consolidation or similar transaction, the stockholders of the Company immediately prior thereto do not Own, directly or indirectly, either (A) outstanding voting securities representing more
than fifty percent (50%) of the combined outstanding voting power of the surviving Entity in such merger, consolidation or similar transaction or (B) more than fifty percent (50%) of the combined outstanding voting power of
the parent of the surviving Entity in such merger, consolidation or similar transaction, in each case in substantially the same proportions as their Ownership of the outstanding voting securities of the Company immediately prior to such transaction;

 (3) the stockholders of the Company approve or the Board approves a plan of complete dissolution or liquidation of the Company,
or a complete dissolution or liquidation of the Company will otherwise occur, except for a liquidation into a parent corporation; or

of the Company and its Subsidiaries, other than a sale, lease, license or other disposition of all or substantially all of the consolidated assets of the Company and its Subsidiaries to an Entity, more than fifty percent (50%) of the
combined voting power of the voting securities of which are Owned by stockholders of the Company in substantially the same proportions as their Ownership of the outstanding voting securities of the Company immediately prior to such sale, lease,
license or other disposition. 
 Notwithstanding the foregoing or any other provision of this Plan, the term Change in Control shall not
include a sale of assets, merger or other transaction effected exclusively for the purpose of changing the domicile of the Company. Once a Change in Control has occurred, no future events shall constitute a Change in Control for purposes of the
Plan. 
 (f) “Change in Control Period” means the period commencing three (3) months prior to the
Closing of a Change in Control and ending twelve (12) months following the Closing of a Change in Control. 
 (g)
“Change in Control Termination” means an Involuntary Termination that occurs within the Change in Control Period. For such purposes, if the events giving rise to an employee’s


  
 2. 













 
right to resign for Good Reason arise within the Change in Control Period, and the employee’s resignation occurs not later than thirty (30) days after the expiration of the Cure Period
(as defined below), such termination shall be a Change in Control Termination. 
 (h) “Closing” means the
initial closing of the Change in Control as defined in the definitive agreement executed in connection with the Change in Control. In the case of a series of transactions constituting a Change in Control, “Closing” means the first closing
that satisfies the threshold of the definition for a Change in Control. 
 (i) “COBRA” means the Consolidated
Omnibus Budget Reconciliation Act of 1985. 
 (j) “Code” means the Internal Revenue Code of 1986, as amended.

 (k) “Company” means Reneo Pharmaceuticals, Inc. or, following a Change in Control, the surviving entity
resulting from such event. 
 (l) “Covered Termination” means a Regular Termination or a Change in Control
Termination. 
 (m) “Director” means a member of the Board. 

(n) “Eligible Employee” means an employee of the Company that meets the requirements to be eligible to receive
Plan benefits as set forth in Section 2 and is designated in writing as eligible to participate in the Plan by the Plan Administrator.

(within the meaning of Section 13(d) or 14(d) of the Exchange Act), except that “Exchange Act Person” will not include (i) the Company or any Subsidiary of the Company, (ii) any employee benefit plan of the Company or any

the Company’s then outstanding securities. 
 (r) “Good Reason” for an employee’s resignation means
the occurrence of any of the following events, conditions or actions taken by the Company without Cause and without such employee’s consent: (i) a material reduction of such employee’s annual base salary, which is a reduction of at
least 10% of such employee’s base salary (unless pursuant to a salary reduction program applicable generally to the Company’s similarly situated employees); (ii) a material reduction in such employee’s authority, duties or
responsibilities; (iii) a material reduction in the authority, duties, or responsibilities of the supervisor to whom such employee is required to report; (iv) a relocation of such employee’s principal place of employment with the
Company (or successor to the Company, if applicable) to a place that 

  
 3. 













 
increases such employee’s one-way commute by more than fifty (50) miles as compared to such employee’s then-current principal place of
employment immediately prior to such relocation (excluding regular travel in the ordinary course of business); provided that if such employee’s principal place of employment is his or her personal residence, this clause (iv) shall not
apply; provided, however, that in each case above, in order for the employee’s resignation to be deemed to have been for Good Reason, the employee must first give the Company written notice of the action or omission giving rise to
“Good Reason” within thirty (30) days after the first occurrence thereof; the Company must fail to reasonably cure such action or omission within thirty (30) days after receipt of such notice (the “Cure
Period”), and the employee’s resignation must be effective not later than thirty (30) days after the expiration of such Cure Period. 

(s) “Involuntary Termination” means a termination of employment that is due to: (1) a termination by the
Company without Cause or (2) an employee’s resignation for Good Reason, provided that in any case such termination is also a “separation from service,” as such term is defined in Treasury Regulations Section 1.409A-1(h). 
 (t) “Own,” “Owned,”
“Owner,” “Ownership” means a person or Entity will be deemed to “Own,” to have “Owned,” to be the “Owner” of, or to have acquired “Ownership” of securities if

(v) “Plan Administrator” means the Board prior to the Closing and the Representative upon and following the
Closing.

(x) “Regular Termination” means an Involuntary Termination that is not a Change in Control Termination. 

(y) “Subsidiary” means, with respect to the Company, (i) any corporation of which more than 50% of the
outstanding capital stock having ordinary voting power to elect a majority of the board of directors of such corporation (irrespective of whether, at the time, stock of any other class or classes of such corporation will have or might have voting
power by reason of the happening of any contingency) is at the time, directly or indirectly, Owned by the Company, and (ii) any partnership, limited liability company or other entity in which the Company has a direct or indirect interest
(whether in the form of voting or participation in profits or capital contribution) of more than 50%. 
 Section 2. ELIGIBILITY
FOR BENEFITS. 
 (a) Eligible Employee. An employee of the Company is eligible to participate
in the Plan if (i) the Board has designated such employee as eligible to participate in the Plan by providing such person with a Participation Agreement; (ii) such employee has signed and returned such Participation Agreement to the
Company within the period specified therein; (iii) such employee’s employment with the Company terminates due to a Covered Termination; and (iv) such employee meets the other Plan 

  
 4. 













 
eligibility requirements set forth in this Section 2. The determination of whether an employee is an Eligible Employee shall be made by the Plan Administrator, in its sole discretion, and
such determination shall be binding and conclusive on all persons. 
 (b) Release Requirement. In order to be eligible to
receive benefits under the Plan, the employee also must execute a general waiver and release in substantially the form attached hereto as Exhibit A, Exhibit B or Exhibit C, as appropriate (the “Release”),
within the applicable time period set forth therein, but in no event more than fifty (50) days following the date of the applicable Covered Termination, and such Release must become effective in accordance with its terms. The Company, in its
sole discretion, may modify the form of the Release to comply with applicable law and the specific terms of the Covered Termination, which may be incorporated into a termination agreement or other agreement with the employee. 

(c) Exceptions to Benefit Entitlement. An employee who otherwise is an Eligible Employee will not receive benefits under the
Plan in the following circumstances, as determined by the Plan Administrator in its sole discretion: 
 (1) The employee voluntarily
terminates employment with the Company without Good Reason, or terminates employment due to the employee’s death or disability. Voluntary terminations include, but are not limited to, resignation, retirement or failure to return from a leave of
absence on the scheduled date. 
 (2) The employee voluntarily terminates employment with the Company in order to accept employment
with another entity that is wholly or partly owned (directly or indirectly) by the Company or an Affiliate. 
 (3) The employee is
offered an identical or substantially equivalent or comparable position with the Company or an Affiliate. For purposes of the foregoing, a “substantially equivalent or comparable position” is one that provides the employee substantially
the same level of responsibility and compensation and would not give rise to the employee’s right to resign for Good Reason. 

(4) The employee is offered immediate reemployment by a successor to the Company or an Affiliate or by a purchaser of the
Company’s assets, as the case may be, following a Change in Control and the terms of such reemployment would not give rise to the employee’s right to resign for Good Reason. For purposes of the foregoing, “immediate reemployment”
means that the employee’s employment with the successor to the Company or an Affiliate or the purchaser of its assets, as the case may be, results in uninterrupted employment such that the employee does not incur a lapse in pay or
benefits as a result of the change in ownership of the Company or the sale of its assets. 
 (5) The employee is rehired by the
Company or an Affiliate and recommences employment prior to the date benefits under the Plan are scheduled to commence. 
 Section 3.
AMOUNT OF BENEFIT. 
 (a) Severance Benefit. Benefits under the Plan shall be
provided to an Eligible Employee as set forth in the Participation Agreement. 
 (b) Additional Benefits. Notwithstanding the
foregoing, the Company may, in its sole discretion, provide benefits to employees or consultants who are not Eligible Employees (“Non-Eligible Employees”) chosen by the Board, in its
sole discretion, and the provision of any such benefits to 

  
 5. 













 
a Non-Eligible Employee shall in no way obligate the Company to provide such benefits to any other Non-Eligible
Employee, even if similarly situated. If benefits under the Plan are provided to a Non-Eligible Employee, references in the Plan to “Eligible Employee” (and similar references) shall be deemed to
refer to such Non-Eligible Employee. 
 (c) Certain Reductions. The Company, in its
sole discretion, shall have the authority to reduce an Eligible Employee’s severance benefits, in whole or in part, by any other severance benefits, pay and benefits provided during a period following written notice of a plant closing or mass
layoff, pay and benefits in lieu of such notice, or other similar benefits payable to the Eligible Employee by the Company or an Affiliate that become payable in connection with the Eligible Employee’s termination of employment pursuant to
(i) any applicable legal requirement, including, without limitation, the Worker Adjustment and Retraining Notification Act or any other similar state law, (ii) any individually negotiated employment contract or agreement or any other
written employment or severance agreement with the Company, or (iii) any Company policy or practice providing for the Eligible Employee to remain on the payroll for a limited period of time after being given notice of the termination of the
Eligible Employee’s employment, and the Plan Administrator shall so construe and implement the terms of the Plan. Any such reductions that the Company determines to make pursuant to this Section 3(c) shall be made such that any benefit
under the Plan shall be reduced solely by any similar type of benefit under such legal requirement, agreement, policy or practice (i.e., any cash severance benefits under the Plan shall be reduced solely by any cash payments or severance
benefits under such legal requirement, agreement, policy or practice, and any continued insurance benefits under the Plan shall be reduced solely by any continued insurance benefits under such legal requirement, agreement, policy or practice). The
Company’s decision to apply such reductions to the severance benefits of one Eligible Employee and the amount of such reductions shall in no way obligate the Company to apply the same reductions in the same amounts to the severance benefits of
any other Eligible Employee, even if similarly situated. In the Company’s sole discretion, such reductions may be applied on a retroactive basis, with severance benefits previously paid being
re-characterized as payments pursuant to the Company’s statutory obligation. 
 (d)
Parachute Payments. Any provision of the Plan to the contrary notwithstanding, if any payment or benefit an Eligible Employee would receive from the Company pursuant to the Plan or otherwise (“Payment”) would
(i) constitute a “parachute payment” within the meaning of Section 280G of the Code, and (ii) but for this sentence, be subject to the excise tax imposed by Section 4999 of the Code (the “Excise
Tax”), then such Payment will be equal to the Reduced Amount (defined below). The “Reduced Amount” will be either (l) the largest portion of the Payment that would result in no portion of the Payment (after
reduction) being subject to the Excise Tax or (2) the entire Payment, whichever amount after taking into account all applicable federal, state and local employment taxes, income taxes, and the Excise Tax (all computed at the highest applicable
marginal rate, net of the maximum reduction in federal income taxes which could be obtained from a deduction of such state and local taxes), results in such Eligible Employee’s receipt, on an after-tax
basis, of the greatest amount of the Payment. If a reduction in the Payment is to be made so that the Payment equals the Reduced Amount, (x) the Payment will be paid only to the extent permitted under the Reduced Amount alternative, and the
Eligible Employee will have no rights to any additional payments and/or benefits constituting the Payment, and (y) reduction in payments and/or benefits will occur in the following order: (1) reduction of cash payments;
(2) cancellation of accelerated vesting of equity awards other than stock options; (3) cancellation of accelerated vesting of stock options; and (4) reduction of other benefits paid to the Eligible Employee. In the event that
acceleration of vesting of equity award compensation is to be reduced, such acceleration of vesting will be cancelled in the reverse order of the date of grant of the Eligible Employee’s equity awards. In no event will the Company or any
stockholder be liable to any Eligible Employee for any amounts not paid as a result of the operation of this Section 3(d). The professional firm engaged by the Company for general tax purposes as of the day prior to the Closing will perform the


  
 6. 













 
foregoing calculations. If the tax firm so engaged by the Company is serving as accountant or auditor for the acquirer, the Company will appoint a nationally recognized tax firm to make the
determinations required hereunder. The Company will bear all expenses with respect to the determinations by such firm required to be made hereunder. If the tax firm determines that no Excise Tax is payable with respect to a Payment, either before or
after the application of the Reduced Amount, it will furnish the Company and each Eligible Employee with documentation that no Excise Tax is reasonably likely to be imposed with respect to such Payment. Any good faith determinations of the tax firm
made hereunder will be final, binding and conclusive upon the Company and the Eligible Employees. 
 Section 4. RETURN
OF COMPANY PROPERTY. 
 An Eligible Employee will not be entitled to any severance benefit
under the Plan unless and until the Eligible Employee returns all Company Property. For this purpose, “Company Property” means all Company documents (and all copies thereof) and other Company property which the Eligible
Employee had in his or her possession at any time, including, but not limited to, Company files, notes, drawings, records, plans, forecasts, reports, studies, analyses, proposals, agreements, financial information, research and development
information, sales and marketing information, operational and personnel information, specifications, code, software, databases, computer-recorded information, tangible property and equipment (including, but not limited to, computers, facsimile
machines, mobile telephones, servers), credit cards, entry cards, identification badges and keys; and any materials of any kind which contain or embody any proprietary or confidential information of the Company (and all reproductions thereof in
whole or in part). 
 Section 5. TIME OF PAYMENT AND FORM
OF BENEFIT. 
 The Company reserves the right in the Participation Agreement to specify whether severance
payments under the Plan will be paid in a single sum, in installments, or in any other form and to determine the timing of such payments. All such payments under the Plan will be subject to applicable withholding for federal, state and local taxes.
If an Eligible Employee is indebted to the Company on his or her termination date, the Company reserves the right to offset any severance payments under the Plan by the amount of such indebtedness. All severance benefits provided under the Plan are
intended to satisfy the requirements for an exemption from application of Section 409A of the Code to the maximum extent that an exemption is available and any ambiguities herein shall be interpreted accordingly; provided, however, that to the
extent such an exemption is not available, the severance benefits provided under the Plan are intended to comply with the requirements of Section 409A to the extent necessary to avoid adverse personal tax consequences and any ambiguities herin
shall be interpreted accordingly. 
 Notwithstanding anything to the contrary set forth herein, any payments and benefits provided under the
Plan that constitute “deferred compensation” within the meaning of Section 409A of the Code and the regulations and other guidance thereunder and any state law of similar effect (collectively
“Section 409A”) shall not commence in connection with an Eligible Employee’s termination of employment unless and until the Eligible Employee has also incurred a “separation from
service,” as such term is defined in Treasury Regulations Section 1.409A-1(h) (“Separation from Service”), unless the Company reasonably determines that such amounts may be
provided to the Eligible Employee without causing the Eligible Employee to incur the adverse personal tax consequences under Section 409A. 

It is intended that (i) each installment of any benefits payable under the Plan to an Eligible Employee be regarded as a separate
“payment” for purposes of Treasury Regulations Section 1.409A-2(b)(2)(i), (ii) all payments of any such benefits under the Plan satisfy, to the greatest extent possible, the exemptions from the
application of Section 409A provided under Treasury Regulations 

  
 7. 













 
Sections 1.409A-1(b)(4) and 1.409A-1(b)(9)(iii), and (iii) any such benefits consisting of COBRA premiums also
satisfy, to the greatest extent possible, the exemption from the application of Section 409A provided under Treasury Regulations Section 1.409A-1(b)(9)(v). However, if the Company determines that any
such benefits payable under the Plan constitute “deferred compensation” under Section 409A and the Eligible Employee is a “specified employee” of the Company, as such term is defined in Section 409A(a)(2)(B)(i), then,
solely to the extent necessary to avoid the imposition of the adverse personal tax consequences under Section 409A, (A) the timing of such benefit payments shall be delayed until the earlier of (1) the date that is six (6) months
and one (1) day after the Eligible Employee’s Separation from Service and (2) the date of the Eligible Employee’s death (such applicable date, the “Delayed Initial Payment Date”), and (B) the Company
shall (1) pay the Eligible Employee a lump sum amount equal to the sum of the benefit payments that the Eligible Employee would otherwise have received through the Delayed Initial Payment Date if the commencement of the payment of the benefits
had not been delayed pursuant to this paragraph and (2) commence paying the balance, if any, of the benefits in accordance with the applicable payment schedule. 

In no event shall payment of any benefits under the Plan be made prior to an Eligible Employee’s termination date or prior to the
effective date of the Release. If the Company determines that any payments or benefits provided under the Plan constitute “deferred compensation” under Section 409A, and the Eligible Employee’s Separation from Service occurs at a
time during the calendar year when the Release could become effective in the calendar year following the calendar year in which the Eligible Employee’s Separation from Service occurs, then regardless of when the Release is returned to the
Company and becomes effective, the Release will not be deemed effective any earlier than the latest permitted effective date (the “Release Deadline”). If the Company determines that any payments or benefits provided under the
Plan constitute “deferred compensation” under Section 409A, then except to the extent that payments may be delayed until the Delayed Initial Payment Date pursuant to the preceding paragraph, on the first regular payroll date following
the effective date of an Eligible Employee’s Release, the Company shall (1) pay the Eligible Employee a lump sum amount equal to the sum of the benefit payments that the Eligible Employee would otherwise have received through such payroll
date but for the delay in payment related to the effectiveness of the Release and (2) commence paying the balance, if any, of the benefits in accordance with the applicable payment schedule. 

All severance payments under the Plan shall be subject to applicable withholding for federal, state and local taxes. If an Eligible Employee
is indebted to the Company at his or her termination date, the Company reserves the right to offset any severance payments under the Plan by the amount of such indebtedness. 

Section 6. REEMPLOYMENT. 

In the event of an Eligible Employee’s reemployment by the Company during the period of time in respect of which severance benefits
pursuant to the Plan have been paid, the Company, in its sole and absolute discretion, may require such Eligible Employee to repay to the Company all or a portion of such severance benefits as a condition of reemployment. 

Section 7. RIGHT TO INTERPRET AND ADMINISTER PLAN;
AMENDMENT AND TERMINATION. 
 (a) Interpretation and Administration. Prior to
the Closing, the Board shall be the Plan Administrator and shall have the exclusive discretion and authority to establish rules, forms, and procedures for the administration of the Plan and to construe and interpret the Plan and to decide any and
all questions of fact, interpretation, definition, computation or administration arising in connection with the operation of the Plan, including, but not limited to, the eligibility to participate in the Plan and amount of benefits paid under the
Plan. The rules, interpretations, computations and other actions of the Board 

  
 8. 













 
shall be binding and conclusive on all persons. Upon and after the Closing, the Plan will be interpreted and administered in good faith by the Representative who shall be the Plan Administrator
during such period. All actions taken by the Representative in interpreting the terms of the Plan and administering the Plan upon and after the Closing will be final and binding on all Eligible Employees. Any references in this Plan to the
“Board” or “Plan Administrator” with respect to periods following the Closing shall mean the Representative. 

(b) Amendment. The Plan Administrator reserves the right to amend this Plan at any time; provided, however, that any
amendment of the Plan will not be effective as to a particular employee who is or may be adversely impacted by such amendment or termination and has an effective Participation Agreement without the written consent of such employee. Any action
amending the Plan shall be in writing and executed by the Company’s Chairman of the Board or if none, the Company’s Executive Chairman or Chief Executive Officer (prior to the Closing), or the Representative (following the Closing). 

(c) Termination. The Plan will automatically terminate upon the earliest of: (i) the date five (5) years after the
Effective Date, if the Closing has not occurred on or prior to such date, or (ii) following satisfaction of all the Company’s obligations under the Plan. 

Section 8. NO IMPLIED EMPLOYMENT CONTRACT. 

The Plan shall not be deemed (i) to give any employee or other person any right to be retained in the employ of the Company or
(ii) to interfere with the right of the Company to discharge any employee or other person at any time, with or without cause, which right is hereby reserved. 

Section 9. LEGAL CONSTRUCTION. 

This Plan is intended to be governed by and shall be construed in accordance with the Employee Retirement Income Security Act of 1974
(“ERISA”) and, to the extent not preempted by ERISA, the laws of the State of California.

Section 13. STATEMENT OF ERISA RIGHTS. 

Participants in this Plan (which is a welfare benefit plan sponsored by Reneo Pharmaceuticals, Inc.) are entitled to certain rights and
protections under ERISA. If you are an Eligible Employee, you are considered a participant in the Plan and, under ERISA, you are entitled to: 

(a) Receive Information About Your Plan and Benefits. 

(1) Examine, without charge, at the Plan Administrator’s office and at other specified locations, such as worksites, all documents
governing the Plan and a copy of the latest annual report (Form 5500 Series), if applicable, filed by the Plan with the U.S. Department of Labor and available at the Public Disclosure Room of the Employee Benefits Security Administration; 

(2) Obtain, upon written request to the Plan Administrator, copies of documents governing the operation of the Plan and copies of the
latest annual report (Form 5500 Series), if applicable, and an updated (as necessary) Summary Plan Description. The Administrator may make a reasonable charge for the copies; and 

(3) Receive a summary of the Plan’s annual financial report, if applicable. The Plan Administrator is required by law to furnish
each Eligible Employee with a copy of this summary annual report. 
 (b) Prudent Actions by Plan Fiduciaries. In addition to
creating rights for Plan Eligible Employees, ERISA imposes duties upon the people who are responsible for the operation of the employee benefit plan. The people who operate the Plan, called “fiduciaries” of the Plan, have a duty to do so
prudently and in the interest of you and other Eligible Employees and beneficiaries. No one, including your employer, your union or any other person, may fire you or otherwise discriminate against you in any way to prevent you from obtaining a Plan
benefit or exercising your rights under ERISA. 
 (c) Enforce Your Rights. If your claim for a Plan benefit is denied or
ignored, in whole or in part, you have a right to know why this was done, to obtain copies of documents relating to the decision without charge, and to appeal any denial, all within certain time schedules. 

  
 12. 













 Under ERISA, there are steps you can take to enforce the above rights. For instance, if you
request a copy of Plan documents or the latest annual report from the Plan, if applicable, and do not receive them within thirty (30) days, you may file suit in a Federal court. In such a case, the court may require the Plan Administrator to
provide the materials and pay you up to $110 a day until you receive the materials, unless the materials were not sent because of reasons beyond the control of the Plan Administrator. 

If you have a claim for benefits which is denied or ignored, in whole or in part, you may file suit in a state or Federal court. 

If you are discriminated against for asserting your rights, you may seek assistance from the U.S. Department of Labor, or you may file suit
in a Federal court. The court will decide who should pay court costs and legal fees. If you are successful, the court may order the person you have sued to pay these costs and fees. If you lose, the court may order you to pay these costs and fees,
for example, if it finds your claim is frivolous. 
 (d) Assistance with Your Questions. If you have any questions about the
Plan, you should contact the Plan Administrator. If you have any questions about this statement or about your rights under ERISA, or if you need assistance in obtaining documents from the Plan Administrator, you should contact the nearest office of
the Employee Benefits Security Administration, U.S. Department of Labor, listed in your telephone directory or the Division of Technical Assistance and Inquiries, Employee Benefits Security Administration, U.S. Department of Labor, 200 Constitution
Avenue N.W., Washington, D.C. 20210. You may also obtain certain publications about your rights and responsibilities under ERISA by calling the publications hotline of the Employee Benefits Security Administration.

You have been designated as eligible to participate in the Reneo Pharmaceuticals, Inc. Severance Benefit Plan (the

definitions as in the Plan. 
 Section 2. SEVERANCE BENEFITS 

Subject to the terms of the Plan and Section 3 of this Agreement, if you are terminated in a Covered Termination, and meet all the other
eligibility requirements set forth in the Plan, including, without limitation, executing the required Release within the applicable time period set forth therein and provided that such Release becomes effective in accordance with its terms, you will
receive the severance benefits set forth in this Section 2. Notwithstanding the schedule for provision of severance benefits as set forth below, the provision of any severance benefits under this Section 2 is subject to any delay in
payment that may be required under Section 5 of the Plan. 
 (a) Regular Termination. Upon a Regular Termination, you
shall be eligible to receive the following severance benefits. 
 (1) Cash Severance Benefit. You will be entitled to
continue to receive your then-current Base Salary for [___________ (___)] months (such period of months, the “Severance Period”) commencing on the first payroll period following the effective date of your Release. 

(2) [Accelerated Vesting of Stock Awards.  

(i) [Effective as of the effective date of your Release, (i) the vesting and exercisability of all outstanding stock options to
purchase the Company’s common stock that are held by you on such date and subject to time-based vesting requirements, (ii) any then-outstanding reacquisition or repurchase rights held by the Company in respect of common stock issued
pursuant to any other stock award granted to you by the Company subject to a time-based lapse or vesting schedule, and (iii) the vesting of any other stock awards granted to you by the Company subject to time-based vesting requirements, and any
issuance of shares triggered by the time-based vesting of such stock awards, shall in each case of (i), (ii) or (iii) above as applicable be accelerated (or lapse, in the case of reacquisition or repurchase rights subject to a time-based lapse)
as if you had completed an additional twelve (12) months of service with the Company as of the date of your Regular Termination.] 

[Effective as of the effective date of your Release, (i) the vesting and exercisability of all outstanding stock options to purchase the
Company’s common stock that are held by you on such date shall be accelerated in full, (ii) any then-outstanding reacquisition or repurchase rights held by the Company in respect of common stock issued pursuant to any other stock award
granted to you by the Company shall lapse in full, and (iii) the vesting of any other stock awards granted to you 

  
 1. 













 
by the Company, and any issuance of shares triggered by the vesting of such stock awards, shall be accelerated in full. Notwithstanding the foregoing, this Section 2(a)(2)(i) shall not apply
to stock awards issued under or held in any Qualified Plan. For purposes of determining the number of shares that will vest pursuant to the foregoing provision with respect to any performance based vesting award that has multiple vesting levels
depending upon the level of performance, vesting acceleration shall occur with respect to the number of shares subject to the award as if the applicable performance criteria had been attained at a 100% level.] 

(ii) In order to give effect to the intent of the foregoing provision, notwithstanding anything to the contrary set forth in your
stock award agreements (or the applicable equity incentive plan under which such stock award was granted) that provides that any then-unvested portion of your award will immediately expire upon your termination of service, no unvested portion of
your stock award shall terminate any earlier than three (3) months following any Involuntary Termination of your employment that occurs prior to a Closing. Notwithstanding anything to the contrary set forth herein, your stock awards shall
remain subject to earlier termination in connection with a “Corporate Transaction” as provided in the Equity Plan or substantially equivalent provisions applicable to your stock award.] 

(3) Payment of Continued Group Health Plan Benefits. 

(i) If you timely elect continued group health plan continuation coverage under COBRA the Company shall pay the full amount of your
COBRA premiums, or shall provide coverage under any self-funded plan, on behalf of you for your continued coverage under the Company’s group health plans, including coverage for your eligible dependents, for the Severance Period (the
“COBRA Payment Period”). Upon the conclusion of such period of insurance premium payments made by the Company, or the provision of coverage under a self-funded group health plan, you will be responsible for the entire payment
of premiums (or payment for the cost of coverage) required under COBRA for the duration of your eligible COBRA coverage period. For purposes of this Section, (i) references to COBRA shall be deemed to refer also to analogous provisions of state
law and (ii) any applicable insurance premiums that are paid by the Company shall not include any amounts payable by you under an Internal Revenue Code Section 125 health care reimbursement plan, which amounts, if any, are your sole
responsibility. 
 (ii) Notwithstanding the foregoing, if at any time the Company determines, in its sole discretion, that it cannot
provide the COBRA premium benefits without potentially incurring financial costs or penalties under applicable law (including, without limitation, Section 2716 of the Public Health Service Act), then in lieu of paying COBRA premiums on the your
behalf, the Company will instead pay you on the last day of each remaining month of the COBRA Payment Period a fully taxable cash payment equal to the COBRA premium for that month, subject to applicable tax withholding (such amount, the
“Special Severance Payment”), such Special Severance Payment to be made without regard to yours election of COBRA coverage or payment of COBRA premiums and without regard to your continued eligibility for COBRA coverage
during the COBRA Payment Period. Such Special Severance Payment shall end upon expiration of the COBRA Payment Period. 
 (b)
Change in Control Termination. Upon a Change in Control Termination, you shall be eligible to receive the following severance benefits. For the avoidance of doubt, in no event shall you be entitled to benefits under both Section 2(a) and
this Section 2(b). If you are eligible for severance benefits under both Section 2(a) and this Section 2(b), you shall receive the benefits set forth in this Section 2(b) and such benefits shall be reduced by any benefits
previously provided to you under Section 2(a).

 (i) your Severance Period will be [___________ (___)] months and
Base Salary payments will commence on the first payroll period following the later of (i) the effective date of your Release, or (ii) the effective date of the Closing; and 

(ii) you will additionally be entitled to a portion of your target bonus, if any, established for you by the Board for the year in
which your Change in Control Termination occurs, in an amount equal to your annual target bonus for such year, if any, multiplied by the quotient of the Severance Period divided by twelve (12), which shall be payable in a lump sum payment within ten
(10) business days following the later of (i) the effective date of your Release, or (ii) the effective date of the Closing. 

(2) Accelerated Vesting of Stock Awards. 

(i) Effective as of the later of the effective date of your Release or the effective date of the Closing, to the extent not previously
vested: (i) the vesting and exercisability of all outstanding stock options to purchase the Company’s common stock that are held by you on such date shall be accelerated in full, (ii) any reacquisition or repurchase rights held by the
Company in respect of common stock issued pursuant to any other stock award granted to you by the Company shall lapse in full, and (iii) the vesting of any other stock awards granted to you by the Company, and any issuance of shares triggered
by the vesting of such stock awards, shall be accelerated in full. Notwithstanding the foregoing, this Section 2(b)(2) shall not apply to stock awards issued under or held in any Qualified Plan. For purposes of determining the number of shares
that will vest pursuant to the foregoing provision with respect to any performance based vesting award that has multiple vesting levels depending upon the level of performance, vesting acceleration shall occur with respect to the number of shares
subject to the award as if the applicable performance criteria had been attained at a 100% level. 
 (ii) In order to give effect to
the intent of the foregoing provision, notwithstanding anything to the contrary set forth in your stock award agreements or the applicable equity incentive plan under which such stock award was granted that provides that any then unvested portion of
your award will immediately expire upon your termination of service, no unvested portion of your stock award shall terminate any earlier than three (3) months following any Involuntary Termination of your employment that occurs prior to a
Closing. Notwithstanding anything to the contrary set forth herein, your stock awards shall remain subject to earlier termination in connection with a “Corporate Transaction” as provided in the Equity Plan or substantially equivalent
provisions applicable to your stock award. 
 (3) Payment of Continued Group Health Plan Benefits. You will receive the
payment for continued group health plan benefits described in Section 2(a)[(3)] [(2)] above, except that the COBRA Payment Period will be equal to the Severance Period applicable to a Change in Control Termination as set forth in
Section 2(b)(1) above. 
 Section 3. REQUIREMENTS DURING SEVERANCE PERIOD.

law; or (b) any rights that cannot be waived as a matter of law. In addition, I understand that nothing in this Release prevents me from filing, cooperating with, or participating in any proceeding before the Equal Employment Opportunity

 1. 













 I acknowledge that I have read and understand Section 1542 of the California Civil Code
which reads as follows: “A general release does not extend to claims which the creditor does not know or suspect to exist in his or her favor at the time of executing the release, which if known by him or her must have materially affected
his or her settlement with the debtor.” I hereby expressly waive and relinquish all rights and benefits under that section and any law of any jurisdiction of similar effect with respect to my release of any claims I may have against the
Company. 
 I hereby represent that I have been paid all compensation owed and for all hours worked; I have received all the leave and leave
benefits and protections for which I am eligible pursuant to the Family and Medical Leave Act (if applicable), the California Family Rights Act (if applicable) or otherwise; and I have not suffered any on-the-job injury for which I have not already filed a workers’ compensation claim. 
 I
acknowledge that to become effective, I must sign and return this Release to the Company so that it is received not later than fourteen (14) days following the date it is provided to me or such other date as specified by the Company.
