Prohibition Against Insider Trading. You should be aware of the European insider trading rules, which may affect the sale of shares of Common Stock acquired under the Plan.

The Company cannot be held liable if you violate the insider trading rules applicable in the Netherlands. You are responsible for ensuring your compliance with these rules.

Under Article 14 of the Market Abuse Regulation ((EU) Regulation 596/2014), anyone who has “inside information” related to an issuing company is prohibited from effectuating a transaction in securities in or from the Netherlands. “Inside information” is defined as knowledge of specific information concerning the issuing company to which the securities relate or the trade in securities issued by such company, which has not been made public and which, if published, would reasonably be expected to affect the price of the securities, regardless of the development of the price. The insider could be any employee of the Company or an Affiliate in the Netherlands who has inside information as described herein.

Given the broad scope of the definition of inside information, certain participants may have inside information and thus are prohibited from making a transaction in securities in the Netherlands at a time when they have such inside information. By entering into this Agreement and participating in the Plan, you acknowledge having read and understood the notification above and acknowledge that it is your responsibility to comply with the Dutch insider trading rules, as discussed herein.

Securities Disclaimer. The grant of the Award is exempt or excluded from the requirement to publish a prospectus under the Prospectus Regulation ((EU) Regulation 2017/1129). The Awards are not transferable and are not deemed to qualify as an offering of securities in the Netherlands within the meaning of the Prospectus Regulation. To the extent that a supervisory body would qualify the offering of Awards or its underlying securities as an offering of securities within the meaning of the Prospectus Regulation, such offering will only be made in reliance on Article 1(4) of the Prospectus Regulation provided that no such offering of securities shall require Mirum Pharmaceuticals, Inc. to publish a prospectus pursuant to Article 3 of the Prospectus Regulation.

No Entitlement for Claims or Compensation. The following provision supplements Section 10 of the Agreement that clarifies that the grant, vesting, or settlement of Award does not give you a right to continued service/employment:

By accepting the grant of Award, you consent to participation in the Plan and acknowledge that you have received a copy of the Plan document.

You understand that the Company has unilaterally, gratuitously and in its sole discretion decided to make grants of Awards under the Plan to individuals who may be Consultants, Directors, and Employees throughout the world. The decision is limited and entered into based upon the express assumption and condition that any Awards will not economically or otherwise bind the Company or any Affiliate, including the employer, on an ongoing basis, other than as expressly set forth in the Agreement. Consequently, you understand that the grant of Awards is made on the assumption and condition that the Awards shall not become part of any employment contract (whether with the Company or any Affiliate, including the employer) and shall not be considered a mandatory benefit, salary for any purpose (including severance compensation) or any other right whatsoever. Furthermore, you understand and freely accept that there is no guarantee that any benefit whatsoever shall arise from the Awards, which is gratuitous and discretionary, since the future value of the Awards and the underlying shares of Common Stock is unknown and unpredictable.

You understand and agree that, as a condition of the grant of the Awards, your termination of Continuous Service for any reason (including for the reasons listed below) will automatically result in the cancellation and loss of any Awards that may have been granted to you and that were not fully vested on the date of termination of your Continuous Service. In particular, you understand and agree that, unless otherwise expressly provided for by the Company at the Date of Grant, the Awards will be cancelled without entitlement to the shares of Common Stock or to any amount as indemnification if you terminate employment by reason of, including, but not limited to: resignation, death, disability, retirement, disciplinary dismissal adjudged to be with cause, disciplinary dismissal adjudged or recognized to be without cause, individual or collective layoff on objective grounds, whether adjudged to be with cause or adjudged or recognized to be without cause, material modification of the terms of employment under Article 41 of the Workers’ Statute, relocation under Article 40 of the Workers’ Statute, Article 50 of the Workers’ Statute, unilateral withdrawal by the employer, and under Article 10.3 of Royal Decree 1382/1985.

You also understand that this grant of Awards would not be made but for the assumptions and conditions set forth hereinabove; thus, you understand, acknowledge and freely accept that, should any or all of the assumptions be mistaken or any of the conditions not be met for any reason, the grant, the Awards and any right to the underlying shares of Common Stock shall be null and void.

Securities Law Information. The Award described in the Agreement and this Appendix do not qualify under Spanish regulations as securities. No “offer of securities to the public”, as defined under Spanish law, has taken place or will take place in the Spanish territory. The Agreement (including this Appendix) has not been nor will it be registered with the Comisión Nacional del Mercado de Valores, and does not constitute a public offering prospectus.

Foreign Assets Reporting. You may be subject to certain tax reporting requirements with respect to assets or rights that you hold outside of Spain, including bank accounts, securities and real estate if the aggregate value for particular category of assets exceeds EUR €50,000 as of December 31 each year. Shares of

Common Stock acquired under the Plan or other equity programs offered by the Company constitute securities for purposes of this requirement, but unvested awards (e.g., RSU Awards, etc.) are not considered assets or rights for purposes of this reporting requirement.

If applicable, you must report the assets on Form 720 by no later than March 31 following the end of the relevant year. After the rights and/or assets are initially reported, the reporting obligation will only apply if: (i) the value of previously-reported rights or assets increases by more than EUR €20,000 as of each subsequent December 31, or (ii) upon disposition of the previously-reported rights or assets. You are encouraged to consult with your personal advisor to determine any obligations in this respect.

Share Reporting Requirement. You must declare the acquisition, ownership and disposition of shares of Common Stock to the Spanish Dirección General de Comercio e Inversiones (the “DGCI”) of the Ministry of Economy and Competitiveness on a Form D-6. Generally, the declaration must be made in January for shares of Common Stock owned as of December 31 of the prior year and/or shares of Common Stock acquired or disposed of during the prior year; however, if the value of the shares of Common Stock acquired or the amount of the sale proceeds exceeds EUR €1,502,530 (or you hold 10% or more of the share capital of the Company or other such amount that would entitle you to join the Board), the declaration must be filed within one month of the acquisition or disposition, as applicable. You should consult with your personal advisor to determine your obligations in this respect.

Foreign Assets and Transaction Reporting. You may be required to electronically declare to the Bank of Spain any foreign accounts (including brokerage accounts held abroad), any foreign instruments (e.g., shares of Common Stock) and any transactions with non-Spanish residents (including any payments of cash or shares made to you by the Company or a U.S. brokerage account) if the balances in such accounts together with the value of such instruments as of December 31, or the volume of transactions with nonSpanish residents during the prior or current year, exceed EUR €1,000,000. Once the EUR €1,000,000 threshold has been surpassed in either respect, you will generally be required to report all of your foreign accounts, foreign instruments and transactions with non-Spanish residents, even if the relevant threshold has not been crossed for an individual item. You will generally only be required to report on an annual basis (by January 20 of each year); however, if the balances in your foreign accounts together with value of your foreign instruments or the volume of transactions with non-Spanish residents exceed EUR €100,000,000, you acknowledge that more frequent reporting will be required.

Sole Contact and Contractual Partner Information. You acknowledge that the Award, this Agreement including the Appendix and, the Annexes and your participation in the Plan do not create any claims against the employer, either directly or indirectly. Your sole contract and sole contractual partner regarding the Plan and the Award is the Company and the Award does not form part of your contractual compensation.

Continuous Service. Notwithstanding anything else in the Plan or the Agreement, the Continuous Service will be deemed to end on the date when a termination notice is issued, regardless of whether the cessation of the employment was lawful, and shall not include any period notice of termination of employment or any period of salary continuance or deemed employment. As a result, if you receive notice of termination your Continuous Service will end on the date you receive such notice.

Securities Law Information. The Award is not intended to be publicly offered in or from Switzerland.

Award Not a Service Contract. The following supplements Section 10 of the Agreement:

You waive all rights to compensation or damages in consequence of the termination of your office or employment with the Company or any Affiliate for any reason whatsoever (whether lawful or unlawful and including, without prejudice to the foregoing, in circumstances giving rise to a claim for wrongful dismissal) in so far as those rights arise or may arise from you ceasing to hold or being able to vest your Award, or from the loss or diminution in value of any rights or entitlements in connection with the Plan.

As a condition of the vesting of your Award, you unconditionally and irrevocably agree:

(i) to place the Company in funds and indemnify the Company in respect of: (1) all liability to UK income tax which the Company is liable to account for on your behalf directly to HM Revenue & Customs; (2) all liability to national insurance contributions which the Company is liable to account for on your behalf to HM Revenue & Customs (including, to the extent permitted by law, secondary class 1 (employer’s) national insurance contributions for which you are liable and hereby agree to bear); and (3) all liability to national insurance contributions for which the Company is liable and which are formally transferred to you, which arises as a consequence of or in connection with your Award (the “UK Tax Liability”); or

(ii) to permit the Company to sell at the best price which it can reasonably obtain such number of shares of Common Stock allocated or allotted to you following vesting as will provide the Company with an amount equal to the UK Tax Liability; and to permit the Company to withhold an amount not exceeding the UK Tax Liability from any payment made to you (including, but not limited to salary); and

(iii) if so required by the Company, and, to the extent permitted by law, to enter into a joint election or other arrangements under which the liability for all or part of such employer’s national insurance contributions liability is transferred to you; and

(iv) if so required by the Company, to enter into a joint election within Section 431 of (UK) Income Tax (Earnings and Pensions) Act 2003 (“ITEPA”) in respect of computing any tax charge on the acquisition of “restricted securities” (as defined in Section 423 and 424 of ITEPA); and

(v) to sign, promptly, all documents required by the Company to effect the terms of this provision, and references in this provision to “the Company” shall, if applicable, be construed as also referring to any Affiliate.

Clawback/Recovery. By executing the Agreement, you expressly consent in writing to the application of the right of recoupment to your Award in accordance with the terms of Section 8(l) of the Plan and Section 17 of the Agreement.
