SEPARATION AGREEMENT AND RELEASE

This Separation Agreement and Release (“Agreement”) is made by and between Neil Berkley (“Employee”) and Lineage Biosciences, Inc. (the “Company”) and AbCellera Biologics Inc. (“AbCellera”) (collectively referred to as the “Parties” or individually referred to as a “Party”).

RECITALS

WHEREAS, Employee was employed by the Company a wholly-owned subsidiary of AbCellera as the Chief Business Officer;

WHEREAS, Employee executed and agreed to be bound an Employment Agreement (“Employment Agreement”) with the Company on June 8, 2021, which contained certain confidentiality and other terms and further executed and agreed to be bound by an Executive Severance Agreement with the Company and AbCellera on June 9, 2021 and later amended on December 28, 2021, which provided for certain benefits and obligations (“Executive Severance Agreement”);

WHEREAS, the Company terminated Employee’s employment with the Company effective June 29, 2022 (the “Termination Date”); and

WHEREAS, the Parties wish to resolve any and all disputes, claims, complaints, grievances, charges, actions, petitions, and demands that the Employee may have against the Company and AbCellera and any of the Releasees as defined below, including, but not limited to, any and all claims arising out of or in any way related to Employee’s employment with or separation from the Company;

NOW, THEREFORE, in consideration of the mutual promises made herein, the Company and AbCellera and Employee hereby agree as follows:

COVENANTS

a.Payment. Pursuant to the terms and obligations agreed to by the Parties set forth in the Executive Severance Agreement, as the Employee is a Tier 2 Covered Executive, the Company agrees to pay Employee his current base salary of USD $450,000 for a period of twelve

(12) months from the Termination Date, less applicable withholdings. This payment will be made to Employee consistent with Company’s customary and current payroll procedures during the twelve (12) month post-employment period. All base salary payments shall cease after the twelve-month (12) period.

b.COBRA. If Employee elects continuation coverage pursuant to the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended (“COBRA”), within the time period prescribed pursuant to COBRA, the Company shall pay the COBRA premium to provide Employee with such coverage until the earliest of the following: (i) July 1, 2023; (ii) the

Page 1 of 10

DocuSign Envelope ID: F7DBC1FF-65F5-4693-B92E-A83AF74A5718

date Employee has secured other employment; or (iii) the end of Employee’s eligibility under COBRA for continuation coverage for health care. At its option, the Company may, at any time, convert such payments to a payroll tax payment to Employee in an amount equal to its remaining COBRA premium payment obligation to Employee under this subsection, less all applicable withholdings.

2.Equity Award. Previously, at the recommendation of AbCellera’s Chief Executive Officer, the AbCellera Compensation Committee awarded Employee seventy thousand (70,000) Restricted Share Units (RSUs) vesting in equal amounts on an annual basis starting August 1, 2021, for a period of four (4) years. Additionally, the AbCellera Compensation Committee awarded Employee one hundred five thousand (105,000) share options (“Options”) on August 1, 2021, with vesting such that twenty five percent (25%) of the Options vest on the first anniversary date of the award and the remaining Options vesting in equal installments monthly over the next three years. In addition, on December 7, 2021, the AbCellera Compensation Committee awarded Employee one hundred eight thousand two hundred seventy-two (108,272) Options vesting such that twenty five percent (25%) of the Options vest on the first anniversary date of the award and the remaining Options vesting in equal installments monthly over the next three years and sixty eight thousand seven hundred twenty nine (68,729) RSUs vesting in equal amounts on an annual basis starting December 7, 2021, for a period of four (4) years.

As of the Termination Date, no Options or RSUs awarded to Employee as set forth above have fully vested. As part of this Agreement, the AbCellera Compensation Committee has agreed to accelerate the vesting of seventeen thousand five hundred (17,500) RSUs that were awarded to the Employee. The vesting date for said accelerated RSUs shall be June 29, 2022. The Employee has been deemed an insider by AbCellera based on having access to Material Non-public Information related to AbCellera’s 2Q2022 earnings period and has been notified by the AbCellera Compliance Officer that he is prohibited from buying or selling any ABCL common shares until at least August 11, 2022. In view of this trading prohibition, and to the benefit of the Employee, AbCellera shall issue to the Employee seventeen thousand five hundred (17,500) ABCL common shares on August 11, 2022. In connection with said share issuance, Employee understands that on August 11, 2022, there will be taxable event under the U.S. Tax Code payable by the Employee and therefore Employee agrees to either 1) sell a certain number of ABCL shares to cover the tax liability with said proceeds being remitted to AbCellera for handling consistent with Employee’s tax and AbCellera’s payroll obligations; or 2) provide full payment in cash to AbCellera for said tax obligation no later than August 11, 2022.

For the avoidance of doubt, Employee understands and acknowledges that all other outstanding unvested Options and RSUs awarded to the Employee shall not be subject to accelerated vesting and all vesting shall stop as of the Termination Date and Employee shall have no rights to said unvested and terminated Options or RSUs.

EMPLOYEE UNDERSTANDS THAT NEITHER THIS AGREEMENT NOR THE COURSE OF EMPLOYEE’S EMPLOYMENT WITH THE COMPANY OR ABCELLERA, OR ANY OTHER SERVICE TO THE COMPANY OR ABCELLERA, GIVE OR GAVE EMPLOYEE ANY RIGHT, CONTINUING OR OTHERWISE, TO THE REVENUES AND/OR PROFITS OF THE COMPANY OR ABCELLERA AND/OR ANY OTHER RELEASEE (AS DEFINED BELOW) OR ANY  OTHER  INTEREST,  ECONOMIC  OR  OTHERWISE,  IN  THE  COMPANY  OR

ABCELLERA AND/OR ANY OTHER RELEASEE (AS DEFINED BELOW).

3.Other Payment. The AbCellera Compensation Committee has approved a one-time payment in the amount of $173,710 USD to be paid directly to you. This amount reflects the acceleration of vesting on one-quarter of the RSUs awarded to you in December 2021 (equal to 17,182) paid in cash using the June 29, 0222 end of day trading price of $10.11 USD. This payment is taxable and will paid to you within sixty (60) days of acceptance of this entire Agreement.

4.Taxes. The Company agrees to support you with any required Year 2021 and Year 2022 tax filings with the Canadian Revenue Agency (CRA). This support shall include coordination with Company tax advisors and the preparation and filing of any required forms. The Company will provide you a draft copy of any required filings in advance for review. If applicable, the Company will pay for any outstanding taxes owed by you in Canada and reimburse you for any taxes you paid to the CRA. In the case where there is a refund to you, as a result of a payment that the Company has made on your behalf, we will request that you provide the refund back to the Company. The Company will not reimburse you for any fees or costs associated with services you seek for review of Canadian tax matters or any fees of costs associated with any US tax filings for the years 2021 and 2022 and beyond. With respect to any taxes deducted from your payroll in Year 2022 related to corporate travel benefits during your employment (e.g., airfare, accommodations), the Company agrees to fully reimburse you for said deducted taxes within thirty (30) days of the payroll deduction.

5.Benefits. Employee’s health insurance benefits shall cease on the last day of June 2022, subject to Employee’s right to continue his health insurance under COBRA. Employee’s participation in all benefits and incidents of employment, including, but not limited to, vesting in Options and RSUs, and the accrual of bonuses, vacation, and paid time off, ceased as of the Termination Date.

6.Payment of Salary and Receipt of All Benefits. Employee acknowledges and represents that, other than the consideration set forth in this Agreement, the Company has paid or provided all wages, bonuses, accrued vacation/paid time off, reimbursable expenses, and any and all other benefits and compensation due to Employee as set forth in the Employment Agreement and Executive Severance Agreement.
