## Exhibit 10.1

**Exhibit 10.1**

**LEASE TERMINATION AGREEMENT**

&nbsp;&nbsp;&nbsp;&nbsp;THIS LEASE TERMINATION AGREEMENT (this "**Agreement**") is entered into as of April 1, 2026 (the "**Execution Date**"), by and between GNS SOUTH TOWER, LP, a Delaware limited partnership ("**Landlord**"), and KEZAR LIFE SCIENCES, INC., a Delaware corporation ("**Tenant**").

**R E C I T A L S**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A.Landlord, as successor in interest to AP3-SF1 4000 Shoreline, LLC, a Delaware limited liability company, and Tenant are parties to that certain Lease dated August 16, 2017 as amended by that certain First Amendment to Lease dated November 1, 2022 (collectively, the "**Lease**"), with respect to approximately (i) 24,357 rentable square feet of space located on the third (3<sup>rd</sup>) floor and (ii) 23,357 rentable square feet of space located on the fourth (4<sup>th</sup>) floor (as more particularly set forth in the Lease, collectively, the "**Premises**") of the building with an address of 4000 Shoreline Court, San Francisco, California (the "**Building**").

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;B.Landlord and Tenant desire to terminate the Lease, subject to the terms and conditions set forth herein.

**A G R E E M E N T**

&nbsp;&nbsp;&nbsp;&nbsp;NOW, THEREFORE, in consideration of the covenants and agreements hereinafter set forth and for other good and valuable consideration, the receipt and adequacy of which are hereby acknowledged, Landlord and Tenant covenant and agree as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1.<u>Termination of Lease</u>. Subject to the satisfaction of the conditions and contingencies provided herein, the Lease shall terminate effective as of April 1, 2026 (the "**Termination Date**") as though the Termination Date were the then current expiration date of the Lease Term, and Tenant shall surrender and yield up the Premises (inclusive of the Storage Space) to Landlord in the condition required under the Lease, subject to the terms and conditions of this Agreement. After the Termination Date, neither Tenant nor Landlord shall have any further liability or obligation to the other with respect to the Lease, except as expressly set forth herein; provided, however, that any obligations of Tenant which expressly survive the expiration or sooner termination of the Lease and which are not fully performed as of the Termination Date shall survive the termination.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.<u>Surrender of Premises</u>. On or prior to the Termination Date, Tenant, at Tenant's sole cost and expense, shall have (collectively, the "**Surrender Obligations**"): (a) peaceably surrendered to Landlord the Premises, including the alterations, improvements and changes thereto as required by the terms of the Lease, including, without limitation Article 15 thereof; (b) vacated the Premises; (c) terminated the rights of any and all persons or entities which have rights to occupy the Premises; (d) removed from the Premises all personal property owned by Tenant in strict accordance with the terms and provisions of Article 15 of the Lease; (e) complied with the terms and provisions of Section 15.2 of the Lease, and (f) delivered possession of the Premises to Landlord in the condition required by the Lease. For the avoidance of doubt, Landlord and Tenant acknowledge and agree that, in addition to the Premises, the Surrender Obligations shall apply in connection with the Storage Space. Prior to the Termination Date, Tenant may request that Landlord participate in a final walk-through inspection of the Premises, the Storage Space and/or the Building (the "**Walk-Through**") for the purpose of identifying any conditions that are readily observable that the Tenant is required to address prior to the Termination Date. Notwithstanding the foregoing, Landlord's failure to identify any item shall not be deemed a waiver of

------

any right or a limitation on Tenant's obligations expressly set forth in the Lease, and Tenant shall remain responsible for satisfying the Surrender Conditions as of the Termination Date. In addition, any Surrender Conditions that are not readily observable during the Walk-Through shall survive the Termination Date, including, without limitation, any environmental hazards or other latent conditions.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.<u>Reconciliation of Operating Expenses</u>. The parties expressly acknowledge and agree that, notwithstanding any contrary provision contained herein or in the Lease, Landlord shall not be required to reconcile Tenant's Operating Expenses, Tax Expenses and Utilities Costs for Expense Year 2026, and that in connection therewith, (i) Tenant shall not be responsible to make any further payments to Landlord as a result of any underpayment of Tenant's Operating Expenses, Tax Expenses and Utilities Costs based on estimates for the 2026 Expense Year, and (ii) Landlord shall not be responsible to refund to Tenant any overpayment of Operating Expenses, Tax Expenses and Utilities Costs which Tenant may have made to Landlord based on estimates for the 2026 Expense Year.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4.<u>Release</u>. Effective as of the Termination Date, Tenant, on behalf of itself and its affiliated companies, shareholders, officers, directors, agents, employees, successors in interest and assigns, hereby releases and discharges Landlord and Landlord's partners, officers, directors, managers, members, agents, employees, successors in interest and assigns from and against any and all claims, demands, causes of action, liabilities and obligations (collectively, "**Claims**"), known and unknown, foreseen and unforeseen, direct and indirect, in any way arising out of or relating to the Lease, the Premises, and/or Tenant's use and occupancy thereof; it being the express intention of the parties that the foregoing shall be deemed to be a full and general release. Notwithstanding the foregoing, the preceding release shall not apply to the provisions of this Agreement . Without limitation of the foregoing, Tenant hereby waives application of California Civil Code Section 1542, which states:

*"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."*

Tenant's Initials: <u>MB</u> .

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.<u>Access</u>. Subject to applicable law, Landlord may prohibit access by Tenant to the Premises after the Termination Date by changing the locks to the Premises or any other means permitted by the Lease, at law or in equity.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6.<u>Payment of Termination Fee</u>. The parties acknowledge and agree that as of the Execution Date, Tenant's payment obligation for Base Rent, Tenant's Share of Operating Expenses, Tenant's Share of Tax Expenses and Tenant's Share of Utilities Costs for the remainder of the Lease Term are equal to an amount of $1,984,536.88 (the "**Remaining Rent Obligation**"). Simultaneously with Tenant's execution of this Agreement, Tenant shall pay to Landlord a termination fee in the amount of $1,318,453.88 (the "**Termination Fee**") which amount represents Tenant's Remaining Rent Obligation less the amount of the Security Deposit currently held by Landlord in the amount of $666,083.00 (such amount representing the original Security Deposit held by Landlord under the Lease in the amount of $673,683.00 less an amount of $7,600.00 to be applied towards certain repairs and other work to be completed by Landlord to the Premises (the "**Repairs Amount**")) and which Repairs Amount shall be retained by Landlord. In the event that, as of the Termination Date, Tenant has not fully performed all of its obligations under the Lease and this Agreement, including without limitation, satisfaction of the Surrender Conditions (but excluding the repairs and other work covered by the Repairs Amount), then (i) Landlord shall immediately notify Tenant of such failure ("**Notice of Non-Compliance**"), (ii) this

------

Agreement shall be deemed null and void and of no further force and effect, (iii) the remaining amount of the Security Deposit retained by Landlord (i.e., the amount of $666,083.00) shall be deemed to be the "Security Deposit" held by Landlord subject to the express terms and conditions of Article 20 of the Lease and (iv) the Termination Fee (i.e., the amount of $1,318,453.88) shall be applied towards Tenant's payments of Rent coming due for the remainder of the Lease Term, to the extent permitted by applicable law. If Landlord has not provided Tenant with a Notice of Non-Compliance within five (5) business days after the Termination Date, the Premises shall be deemed surrendered in accordance with Section 15.1 of the Lease; provided, however, in no event shall such deemed surrender in any way limit, release, and/or obviate any obligations which by their express terms survive the expiration or earlier termination of the Lease and all such surviving obligations shall continue to survive in full force and effect, including, without limitation, any indemnity obligations of Tenant and/or any obligations of Tenant with respect to Environmental Laws or Hazardous Materials.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7.<u>Waiver</u>. No failure or delay by a party to insist upon the strict performance of any term, condition or covenant of this Agreement, or to exercise any right, power or remedy hereunder shall constitute a waiver of the same or any other term of this Agreement or preclude such party from enforcing or exercising the same or any such other term, condition, covenant, right, power or remedy at any later time.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;8.<u>Authority</u>. Each party hereto warrants that the person signing below on such party's behalf is authorized to do so and to bind such party to the terms of this Agreement.

This Agreement becomes effective only upon the execution by Landlord and Tenant.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;10.<u>Governing Law</u>. This Agreement and all provisions hereunder shall be governed by and construed in accordance with the laws of the State of California without reference to any conflict of law provisions.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;11.<u>Entire Agreement; No Amendment</u>. This Agreement (including the recitals herein and exhibits hereto, which are incorporated herein by this reference) constitutes the entire agreement and understanding between the parties with respect to the subject of this Agreement and shall supersede all prior written and oral agreements concerning this subject matter. This Agreement may not be amended, modified or otherwise changed in any respect whatsoever except by a writing duly executed by authorized representatives of Landlord and Tenant. Each party acknowledges that it has read this Agreement, fully understands all of this Agreement's terms and conditions, and executes this Agreement freely, voluntarily and with full knowledge of its significance. Each party to this Agreement has had the opportunity to receive the advice of counsel prior to the execution hereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;12.<u>Agreement to Perform Necessary Acts</u>. Each party agrees that upon demand, it shall promptly perform all further acts and execute, acknowledge, and deliver all further instructions, instruments and documents which may be reasonably necessary or useful to carry out the provisions of this Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;13.<u>Brokers</u>. Landlord and Tenant each represent and warrant to the other that no broker, agent, or finder has procured or was involved in the negotiation of this Agreement and no such broker, agent or finder is or may be entitled to a commission or compensation in connection with this Agreement. Landlord and Tenant shall each indemnify, defend, protect and hold the other harmless from and against

------

any and all liability, loss, damages, claims, costs and expenses (including reasonable attorneys' fees) resulting from claims that may be asserted against the indemnified party in breach of the foregoing warranty and representation.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;14.<u>Time</u>. Time is of the essence hereof.

While this Agreement does not limit your right to receive a government-issued award for information provided to any Government Agency in connection with a government whistleblower program or protected whistleblower activity, you understand and agree that, to maximum extent permitted by law, you are otherwise waiving any and all rights you may have to individual relief based on any claims that you have released and any rights you have waived by signing this Agreement. Nothing in this Agreement: (i) prevents you from discussing or disclosing information about unlawful acts in the workplace, such as harassment or discrimination or any other conduct that you have reason to believe is unlawful; or (ii) waives any rights you may have under Section 7 of the National Labor Relations Act (subject to the release of claims set forth herein).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**20.Representations.** You hereby represent that you have been paid all compensation owed and for all hours worked, have received all the leave and leave benefits and protections for which you are eligible pursuant to the Family and Medical Leave Act, the California Family Rights Act, or otherwise, and have not suffered any on-the-job injury for which you have not already filed a workers' compensation claim.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**21.General.** This Agreement, including its exhibits, constitutes the complete, final and exclusive embodiment of the entire agreement between you and the Company with regard to its subject matter.

This Agreement will be deemed to have been entered into and will be construed and enforced in accordance with the laws of the State of California without regard to conflict of laws principles. Any ambiguity in this Agreement shall not be construed against either party as the drafter. Any waiver of a breach of this Agreement shall be in writing and shall not be deemed to be a waiver of any successive breach. This Agreement may be executed in counterparts and electronic signatures will suffice as original signatures.

While this Agreement does not limit your right to receive a government-issued award for information provided to any Government Agency in connection with a government whistleblower program or protected whistleblower activity, you understand and agree that, to maximum extent permitted by law, you are otherwise waiving any and all rights you may have to individual relief based on any claims that you have released and any rights you have waived by signing this Agreement. Nothing in this Agreement: (i) prevents you from discussing or disclosing information about unlawful acts in the workplace, such as harassment or discrimination or any other conduct that you have reason to believe is unlawful; or (ii) waives any rights you may have under Section 7 of the National Labor Relations Act (subject to the release of claims set forth herein).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**20.Representations.** You hereby represent that you have been paid all compensation owed and for all hours worked, have received all the leave and leave benefits and protections for which you are eligible pursuant to the Family and Medical Leave Act, the California Family Rights Act, or otherwise, and have not suffered any on-the-job injury for which you have not already filed a workers' compensation claim.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**21.General.** This Agreement, including its exhibits, constitutes the complete, final and exclusive embodiment of the entire agreement between you and the Company with regard to its subject matter. It is entered into without reliance on any promise or representation, written or oral, other than those expressly contained herein, and it supersedes any other such promises, warranties or representations. This Agreement may not be modified or amended except in a writing signed by both you and a duly authorized officer of the Company. This Agreement will bind the heirs, personal representatives, successors and assigns of both you and the Company, and inure to the benefit of both you and the Company, their heirs, successors and assigns. If any provision of this Agreement is determined to be invalid or unenforceable, in whole or in part, this determination will not affect any other provision of this Agreement and the provision in question will be modified so as to be rendered enforceable. This Agreement will be deemed to have been entered into and will be construed and enforced in accordance with the laws of the State of California without regard to conflict of laws principles. Any ambiguity in this Agreement shall not be construed against either party as the drafter. Any waiver of a breach of this Agreement shall be in writing and shall not be deemed to be a waiver of any successive breach. This Agreement may be executed in counterparts and electronic signatures will suffice as original signatures.

**Re:&nbsp;&nbsp;&nbsp;&nbsp;Separation Agreement**

Dear Mark:

This separation agreement (the "**Agreement**") summarizes the terms of your separation from Kezar Life Sciences, Inc. (the "**Company**") and sets forth the severance benefits offered to you by the Company pursuant to your Executive Employment Agreement, dated as of March 20, 2025 (the "**Executive Employment Agreement**").

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**1.Employment Status and Final Payments.** 

2.**&nbsp;&nbsp;&nbsp;&nbsp;(a)&nbsp;&nbsp;&nbsp;&nbsp; Separation Date**. Your last day of work with the Company and your employment termination date will be the closing date (the "**Closing Date**") of the transactions contemplated by that certain Agreement and Plan of Merger, by and among, the Company, Aurinia Pharma U.S., Inc. and Aurinia Merger Sub, Inc. (the "**Transaction**"), or such earlier date as determined by you and the Board of Directors. If termination occurs earlier than the Closing Date, the actual date of termination shall become the "**Separation Date**" for purposes of this Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.**&nbsp;&nbsp;&nbsp;&nbsp;(b)&nbsp;&nbsp;&nbsp;&nbsp;Accrued Salary**. On the Separation Date, the Company will pay you all accrued salary earned through the Separation Date, subject to standard payroll deductions and withholdings. You are entitled to this payment regardless of whether or not you sign this Agreement.

4.**&nbsp;&nbsp;&nbsp;&nbsp;(c)&nbsp;&nbsp;&nbsp;&nbsp;Expense Reimbursements.** You agree that at least seven (7) days prior to the Separation Date, you will submit your final documented expense reimbursement statement reflecting all business expenses you incurred through the Separation Date, if any, for which you seek reimbursement. The Company will reimburse you for these expenses.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**5.Severance Benefits.** In full satisfaction of any obligations for the Company to provide you with severance benefits in accordance with your Executive Employment Agreement, if you timely sign and return this Agreement to the Company and allow the releases set forth herein to become effective, then the Company will provide you with the following "**Severance Benefits**":

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6.**(a)&nbsp;&nbsp;&nbsp;&nbsp;Cash Severance**. The Company will pay you cash severance equal to (i) the sum of your Monthly Base Salary and Pro-Rata Bonus (each as defined in your Executive Employment Agreement) multiplied by (ii) twelve (12) months (the "**Severance Payment**"). Your Severance Payment will be paid to you in a lump sum, less applicable payroll deductions and withholdings, on the Separation Date, provided that the Agreement is effective by that date.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7.**(b)&nbsp;&nbsp;&nbsp;&nbsp;COBRA Premiums**. The Company will pay you a fully taxable, one-time cash payment equal to the applicable monthly premium for you, your spouse and any dependents for the group health plan maintained by the Company as of your Separation Date, plus a gross-up amount intended to cover a portion of ordinary income tax attributable to the cash payment, multiplied by twelve (12) months (the "**COBRA Payment**") The Company will pay you the COBRA Payment, less applicable deductions and withholdings, on the Separation Date, provided that the Agreement is effective by that date.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**8.Equity.** Pursuant to the terms of your Executive Employment Agreement, the vesting and exercisability of all outstanding stock options held by you on the Separation Date, which were granted under the Company's 2018 Equity Incentive Plan (the "**Equity Plan**"), shall be accelerated in full in connection with the Transaction. Your stock options shall continue to be governed by the terms of the applicable grant notices, stock option agreements and the Equity Plan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**9.Other Compensation or Benefits.** By executing this Agreement, you acknowledge and agree that the Company's obligation to provide you with any severance benefits or any other payments are hereby extinguished (except for the benefits described in this Agreement). You further expressly acknowledge and agree that the Severance Benefits provided herein are in full and complete satisfaction of the Company's obligations, if any, to pay you any severance or termination payments contemplated in the Executive Employment Agreement, as well as any other agreements, plans, and policies. You acknowledge that, except as expressly provided in this Agreement, you have not earned and will not receive from the Company any additional compensation (including base salary, bonus, incentive compensation, commissions, stock or equity interests), severance or benefits before or after the Separation Date, with the exception of any vested right you may have under the express terms of a written ERISA-qualified benefit plan (e.g., 401(k) account) or any vested stock options under the Plans. The gross-up amount of any COBRA Payment will be based on your top tax-bracket as determined solely by adding cash amounts paid to you by the Company in the relevant calendar year and will not include any other source of income, non-tax benefits or equity compensation.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**10.Return of Company Property.** By the close of business on the Separation Date, you agree to return to the Company all Company documents (and all copies thereof) and other Company property which you have in your possession or control, including, but not limited to, Company files, notes, correspondence, email, notebooks (including laboratory notebooks) drawings, records, plans, forecasts, data, reports, compilations of data, studies, analyses, proposals, agreements, financial information, legal files and information, research and development information, vendor lists, prospect information, operational and personnel information, specifications, databases, computer-recorded information, tangible property and equipment, 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).
