This Separation Agreement and General Release (“Agreement”) is between Smith Micro Software, Inc. (“Company”) and Gail Mackiewicz Redmond (“Employee”).

WHEREAS, the Company terminated Employee’s employment on May 2, 2022 (“Termination Date”);

WHEREAS, the Company is willing to pay Employee certain severance in exchange for a release of claims and other commitments.

NOW THEREFORE, intending to be legally bound and for good and valuable consideration, Company and Employee agree as follows:

1.Recitals. The foregoing recitals are true and correct and incorporated herein.

2.Termination of Employment.

(a)The Company timely paid or will timely pay Employee, in accordance with its normal payroll and other procedures (or as otherwise required by law), for (i) Employee’s work through the Termination Date, (ii) Employee’s accrued but unused vacation pay as of the Termination Date, (iii) Employee’s earned sales commission as of the Termination Date, which amounts to $53,533.60, and (iv) Employee’s properly reported and reimbursable business expenses.

(b)Employee’s eligibility to participate in the Company’s group insurance and other welfare benefit plans and programs ceased as of the Termination Date, except that Employee’s group insurance medical benefits ceased or will cease on May 31, 2022, unless otherwise extended under COBRA.

(c)The foregoing payments and benefits have been or will be provided to Employee regardless of whether Employee signs or revokes this Agreement.

3.Severance Benefits. In exchange for the promises herein (including this Agreement becoming effective and Employee abiding by its terms), the parties agree:

(d)Severance Payment. The Company will pay Employee severance in an amount equal to $99,615.42, less all required tax withholdings and other deductions (“Severance”). The Company will pay Severance in six equal semi-monthly installments with the first such installment payment occurring on the first standard semi-monthly payroll date of the month immediately after this Agreement becomes final, binding, and irrevocable (as described below).

(e)COBRA Payment. If Employee timely elects to continue Employee’s group health benefits under COBRA, the Company agrees to pay the full monthly cost of Employee’s COBRA premiums for four (4) months of coverage from June 1, 2022 through September 30, 2022 (which is $2,147.30 per month by the Company) or when Employee ceases to be eligible for COBRA, whichever occurs first. Thereafter, Employee must pay the full cost of Employee’s COBRA premiums to continue Employee’s COBRA coverage.

(f)Vesting of Restricted Shares. In further consideration for Employee entering into this Agreement, and notwithstanding any contrary provision of the applicable award agreement, pursuant to Section 4.3 of the Company’s 2015 Omnibus Equity Incentive Plan (as amended, the “2015 Plan”), all of the shares of restricted stock issued to Employee pursuant to

restricted stock awards under the 2015 Plan which were unvested as of the Termination Date shall be accelerated and shall become fully vested immediately upon the effectiveness of this Agreement. Such shares are not eligible to receive any tax gross up and will be subject to the same share withholding procedure for the payment of any applicable taxes as the Company has applied to Employee's previous stock vesting.

The Severance and other benefits described in this Section 3 are referred to herein as the “Severance Benefits.”

4.Release of Claims.

(a)Release of all Releasable Claims. Subject to Sections 4(b) and (c), Employee, on behalf of Employee and Employee’s heirs and personal representatives, hereby releases and forever discharges the Company, its direct and indirect subsidiaries, divisions, parents, affiliates, companies under common control of any of the foregoing predecessors, successors, and assigns, and its and their past, present, and future shareholders, partners, principals, managers, members, directors, officers, employees, agents, attorneys, insurers, employee benefit plans, trustees, and all others acting in concert with them (collectively, the “Released Parties”), from any and all claims, actions, suits, proceedings, complaints, causes of action, grievances, debts, costs, and expenses (including attorney’s fees), at law or in equity, known or unknown, that Employee has or may have through the date Employee signs this Agreement, arising out of, based on, or relating in any way to any acts or omissions that occurred, in whole or in part, prior to the time that Employee signs this Agreement, including, but not limited to, claims for breach of any express or implied contract, wrongful termination, retaliation, defamation of character, personal injury, intentional or negligent infliction of emotional distress, discrimination or harassment based on race, religion, sex, age, color, handicap and/or disability, national origin, or any other protected class and any other claim based on or related to Employee’s employment with the Company or Employee’s departure therefrom, including, but not limited to, claims for violation of the Employee Retirement Income Security Act of 1974, Title VII of the Civil Rights Act of 1964, the Age Discrimination in Employment Act of 1967, the Americans with Disabilities Act, the Family and Medical Leave Act, the False Claims Act, Florida Civil Rights Act; the Florida Whistleblower’s Act; and any other federal, state, or local statute or regulation, all as amended.
