Separation Agreement between Aurinia Pharmaceuticals Inc. and Rob Huizinga dated October 20, 2022

Further to our recent discussions, as you are aware, the Company wished for you to assume the role of Senior Vice President, Medical Affairs, pursuant to your current terms and conditions of employment (including with respect to compensation and benefits). We view the position of Senior Vice President, Medical Affairs, as comparable to your current role of Executive Vice President, Research, and, in any event, as set out in your employment agreement with the Company dated October 1, 2018 (the “Employment Agreement”), the Company may vary or add to your position, duties and functions from time to time. However, we understand that this is not an arrangement you wish to accept, and that you wish to end your employment.

As such, this letter confirms that you and the Company have mutually agreed that your employment with the Company will come to an end, effective October 31, 2022 (the “End Date”). This letter also sets forth details regarding the end of your employment and makes a without prejudice severance offer in exchange for a full and final Release in favour of the Company.

From now until the End Date (the “Working Notice Period”), you will be expected to perform your assigned duties and responsibilities to the best of your ability, and you will continue to receive your usual compensation and benefits, less applicable deductions and withholdings.

Following the End Date, the balance of all outstanding wages, including any accrued and unused vacation pay, will be paid to you in a lump sum. Your accrued and unused vacation entitlements will be paid out on October 31, 2022, and are as follows:

    Accrued (unused) vacation = 149.83 hours ($41,643.62 CAD) (provided no vacation is taken between now and the End Date)

    Grandfathered vacation = 770.54 hours ($163,633.52 CAD)

These amounts are subject to the usual deductions, and you will be paid these amounts regardless of whether you accept the without prejudice severance offer detailed below.

Note that, in the event that you are terminated for just cause or resign from your employment prior to the end of the Working Notice Period, all payments and benefits will cease and you will not receive any further compensation or pay in lieu, except as may be minimally required pursuant to the British Columbia Employment Standards Act.

After the end of the Working Notice Period, your Record of Employment will be submitted electronically to Service Canada, which you will be able to access online on the Service Canada website. We encourage you to visit the Service Canada website at: https://www.canada.ca/en/services/benefits/ei.html to familiarize yourself with the available Employment Insurance (EI) application process and support services offered by the Canadian Government.

After the end of the Working Notice Period, outstanding unreimbursed business expenses will be paid within the Company’s normal policies for expense reimbursement following submission of the expense report.

On or before the End Date, please return to the Company all its property, including, but not limited to, building access card, laptop, iPad, passwords, computer usernames, voicemail code, phone cards, company credit card, keys, internal policies, and other confidential business information and documents, and any other property belonging to the Company. Please also destroy or delete all tangible or electronic copies of any such property after returning it to the Company.

We wish to remind you that, despite the cessation of your employment with the Company, you continue to be bound by:

    The Confidentiality and Work Product Ownership Agreement attached as Schedule B to the Employment Agreement;

    All restrictive covenants contained in the Employment Agreement, including paragraph 24 (Restrictive Covenant) of the Employment Agreement; and

    All fiduciary duties that arise from your employment.

The Company expects you to comply with these obligations, which survive the cessation of your employment.

Subject to provider approval and the terms and conditions of the applicable plans, the Company will maintain your Medical, Dental, and Vision benefits until the earlier of:

i.     the date you obtain replacement benefits; or

ii.     twelve (12) months from the End Date,

after which time you will be responsible for obtaining your own replacement benefits.

Coverage for your Short Term & Long-Term Disability, Life Insurance, AD&D, Group Retirement Savings Plan, and all other benefits other than Medical, Dental, and Vision benefits, will terminate as of the End Date, October 31, 2022, and you will be responsible for obtaining your own replacement benefits.

There may be conversion options available to you through Sun Life that are subject to strict time limitations (e.g., within 31 days of your coverage termination date):

    Please call Sun Life Client Services at ###-###-#### if you want to exercise conversion options or if you have any questions or require further information about this coverage.

    Please contact Manulife at gromail@manulife.com or ###-###-#### for details regarding transferring your Group Retirement Savings Plan (RRSP) and your Non-registered Savings Plan (NRSP) or any other plans you hold for your retirement savings.

Any unvested options that you received under the Company’s Equity Incentive Plan will be cancelled on the End Date, October 31, 2022.

You have the right to exercise your vested options for a period of 90 days post termination, after which time your vested options will be cancelled. Please direct any inquiries regarding stock options to securities@auriniapharma.com.

As the Company did not wish to terminate your employment, and your employment is coming to an end only by mutual agreement, the Company has no legal obligation to provide you with any termination notice entitlements under statute, contract, or otherwise. However, on the condition that you:

    Remain with the Company and continue to perform all of your assigned duties and responsibilities to the best of your ability until the end of the Working Notice Period;

    Resign any directorship or office held in the Company, or any subsidiary or affiliated companies of the Company, effective as of the End Date;

    Sign the attached Release on or after the End Date (i.e., after the end of the Working Notice Period), and return it to us within two (2) business days after the End Date; and

    Keep the terms of the offer confidential,

the Company is prepared to offer you a severance package on the following terms, in full and final satisfaction of all claims you may have against the Company and any affiliated company:

a)    The Company will pay to you a lump-sum payment of $740,921.94 CAD, less applicable statutory deductions and withholdings, which represents eighteen (18) months of your annualized Base Salary (the “Severance Payment”), which will be paid on January 15, 2023, per your request;

b)    The Company will pay to you a lump-sum payment of $246,974.00 CAD, less applicable statutory deductions and withholdings, representing a target bonus payment equal to 50% of your Base Salary, which will be paid on March 15, 2023;

c)    You will continue to be eligible to receive the Retention Incentive set out at Section 8 of the Employment Agreement; and

d)    The Company will provide you with a 12-month career transition services package through Lee Hecht Harrison (LHH), which can be activated commencing on November 1, 2022 through to October 31, 2023.

For clarity, you will not be entitled to receive the severance package set out above if you terminate your employment for any reason, including if you resign, or if you have been terminated for just cause, prior to the end of the Working Notice Period.

As mentioned above, this without prejudice severance offer is made in full and final satisfaction of all claims you may have against the Company and its related entities. Accordingly, it is a condition of this

offer that you sign the attached Release on or after the End Date (i.e., after the end of the Working Notice Period), and that you keep the terms of the offer confidential.

You may wish to obtain legal advice with respect to this offer.

If you wish to accept this offer, please sign and return a copy of this letter to us by no later than October 31, 2022. As set out above, you must sign and return the signed Release to us within two (2) business days after the End Date.

If you have any questions, please feel free to contact me.

I have read and understand the terms of this letter and the enclosed Release and confirm that I voluntarily accept the terms offered above in full and final satisfaction of all claims which I might have against Aurinia Pharmaceuticals Inc. and its related entities, including but not limited to those relating to or arising out of my employment with Aurinia Pharmaceuticals Inc. or the cessation of my employment.
