Re:    Separation Agreement (“Agreement”)

Dear Brian:

We would like to assure a smooth transition for you and Tandem Diabetes Care, Inc. (the “Company”) as you separate from employment with the Company. Though the Company does not have a formal severance pay plan that applies under these circumstances, we are offering you a severance package as detailed below to ease your transition to other opportunities.

This letter sets forth the severance package that the Company is offering, and the terms and conditions that apply if you accept it. Please read this carefully and feel free to call me if you have any questions. You have until September 7, 2023, to review this agreement and have the right to consult with an attorney of your choosing before signing it.

If the terms set forth in this letter are acceptable, you will need to sign and date the enclosed copy of this letter and return it to me within the time limits set forth below. Once the letter takes effect, it will become a legally binding contract between you and the Company on the following terms:

1.Separation Date: Your employment with the Company will be terminated as of June 28, 2024 (“Separation Date”).

2.Change of Position and Termination of Employment Severance Agreement: As of December 29, 2023, you will no longer serve as Tandem’s Executive Vice President and Chief Commercial Officer and you will no longer be an officer of Tandem. The February 1, 2016, Employment Severance Agreement between you and Tandem will be terminated as of December 29, 2023.

3.Administrative Leave with Pay: Except as provided in Section 4 below, you shall be on administrative leave with pay beginning December 30, 2023, continuing until the Separation Date (the “Admin Leave Period”). Prior to the Admin Leave Period, you will continue to receive all salary payable to you, all employment benefits, and vesting of stock options and RSUs. During the Admin Leave Period, you will (i) continue to be paid your base salary, (ii) you will receive your 2023 corporate bonus minus appropriate withholding and payroll deductions on the date designated by the Board of Directors for payment of the 2023 corporate bonus; (iii) your stock options and RSUs will continue to vest through the Separation Date consistent with the terms of the applicable stock option plans; and (iv) you will receive other employment benefits only as set forth in this Agreement. During the Admin Leave Period you will not perform any duties for or engage in any other activities or communications on behalf of the Company except as provided in Section 13 below. In the event you are contacted by a third-party regarding Company business, you shall forward the communication to John Sheridan, or if the contact is by telephone also tell the caller to contact John Sheridan.

4.Termination of Administrative Leave: In the event you materially breach any of the terms of this Agreement during the Admin Leave Period, as determined by the Company, written notice shall be provided to you and you will cease being on administrative leave, your Separation Date shall be advanced to the date of such written notice, and you shall cease receiving any further payments and cease receiving any benefits as provided under Sections 3 above.

5.Compensation: You acknowledge and agree that as of the date you sign this Agreement, and except for the obligations created by this Agreement, you have been paid all compensation to which you are entitled in connection with your employment with the Company. You further acknowledge and agree that this Agreement is entered into to resolve any and all of the Claims described below, including but not limited to any and all Claims for wages or compensation of any type of character, all such Claims being disputed in good faith.

6.Expense Reimbursement: The Company will reimburse you for any reasonable and necessary business expenses incurred prior to December 29, 2023, in accordance with the Company’s written policies, provided you submit a properly documented expense report by January 12, 2024. Such expense reports shall be provided in writing to the Company’s Human Resources department.

7.Return of Company Property: Within ten (10) business days from December 29, 2023, you must return all property of the Company in your possession or control, including all keys, cards, and badges, all computer, tablet, telephone, electronic devices, and office equipment in good working order (except for reasonable wear and tear) and with all files and software intact, and all electronically stored documents or files, physical files, and any other Company property in your possession. You understand and agree that you shall not retain in your possession or control any duplicate records or files containing confidential information of the Company, whether in electronic, paper or other format or on any storage device or network. Immediately upon request by the Company, you will provide the Company with any passwords associated with any computer, tablet, other device or any application or system used by you in the course of your employment.

8.Group Medical Insurance: Your coverage under the Company’s health insurance plan shall cease effective December 31, 2023. The Company will pay the COBRA premium for you and your covered dependent’s current coverage under the Company’s group medical plan from January 1, 2024, to June 30, 2024, provided you make a timely election to continue such coverage for the period after December 31, 2023. You will receive the necessary COBRA forms in a separate letter from IGOE Administrative Services, our COBRA administrator. Any coverage under the medical plan beyond this period will be solely at your expense. All such coverage will be subject to the terms and conditions of the medical plan documents. Should you wish to discontinue the COBRA coverage at any time, you may choose to do so. To do this, you will need to notify IGOE directly.

9.Unemployment: The Company will not contest your eligibility for unemployment insurance.

10.Stock Options, RSUs and ESPP: Any stock options and RSUs previously issued to you that become vested on or before your Separation Date may be exercised in accordance with the applicable stock option plan, your stock option and RSU agreements, and applicable laws. You have ninety (90) days from the Separation Date to exercise your vested stock options. Upon expiration of this exercise period, all of your vested and unexercised stock options will expire.
