Re:       Separation Agreement

Dear Garrett:

The purpose of this letter agreement (the “Agreement”) is to set forth the terms of your separation from Sera Prognostics, Inc. (the “Company”), and the entirety of the understanding between you, Garrett Lam, on the one hand and the Company on the other, with respect thereto. This Agreement supersedes the terms of the employment agreement dated as of June 13, 2018 (the “Employment Agreement”) in all respects except as to the sections 2(b), 5, 6, 7, 8 and 9 of the Employment Agreement, to the extent that those sections do not conflict with the express terms of this Agreement (in which case the terms of this Agreement shall prevail). Payment of the Severance Pay described below is contingent on your agreement to and compliance with the terms of this Severance Agreement. Neither this offer to you nor the Company’s entering into this Severance Agreement shall constitute an admission by the Company.

Separation of Employment.

a)       Your employment with the Company will end on June 19, 2020 (the “Separation Date”). You acknowledge and agree you will continue to devote your full time and attention and best efforts to performing the duties assigned to you (including the transition of your responsibilities to the individual(s) identified by the Company) and you will comply with all existing Company rules, regulations, policies and directives through the Separation Date. You further acknowledge and agree that, from and after the Separation Date, you shall have no authority to, and shall not, represent yourself as an employee of the Company.

b)       Following the Separation Date, the Company will communicate your separation from the Company to internal and external parties. That communication shall consist of the following language: “Garrett Lam has resigned from Sera Prognostics to pursue other activities.” The Company’s response to inquiries regarding your separation will be consistent with Section 4(f) below.

c)       Notwithstanding your separation from the Company, you will continue as a corresponding author of the Markenson et al. 2020 TREETOP publication in the American Journal of Obstetrics & Gynecology Maternal Fetal Medicine (https://doi.org/10.1016/j.ajogmf.2020.100140), and coordinate responses to queries with all the authors (Company and non-Company) of such paper.

Severance Pay.

a)       In exchange for the mutual promises set forth in this Agreement, the Company agrees to provide severance pay to you in a lump sum of one hundred eighty-two thousand dollars ($182,000.00) less all applicable federal, state, local and other employment-related deductions (“the Payment”). The Company also will provide you with a monthly payment equivalent to your COBRA payment beginning on July 1, 2020 to cover the cost of the continuation of your health insurance coverage through the earlier of (1) June 30, 2021 or (2) the date when you become eligible to receive health insurance coverage in connection with new employment or self-employment (the “COBRA Payment”). You will receive a Form 1099 at each taxable year’s end for the COBRA Payments received within that taxable year. The Payment and the COBRA Payment, together, are referred to as the “Severance Pay.” The Payment and the then-due COBRA Payment(s) will be provided to you within ten (10) days of the Effective Date, which date constitutes the eighth day following the Execution Date, (as that term is defined below). The Severance Pay, including each successive COBRA Payment, will be made by check made payable to Garrett Lam, by sending the Severance Pay and/or COBRA Payment(s) to you via overnight mail at 1864 E. Mountain Crest Drive, Draper, UT 84020.

b)       Regardless of whether you sign this Agreement, you will have the right to continue your medical insurance pursuant to the provisions of the Consolidated Omnibus Budget Reconciliation Act of 1985 (COBRA). You will receive your COBRA notice under separate cover. If you do not sign this agreement and do not elect COBRA, your health insurance (if applicable) will cease on June 30, 2020.

c)       In addition to the Severance Pay, and regardless of whether you sign this Agreement, you will receive payment for your accrued wages through your Separation Date and your unused but accrued vacation pay through your Separation Date, less all applicable federal, state, local deductions.

d)       You acknowledge and agree that the Severance Pay is not otherwise due or owing to you under any Company employment agreement (oral or written) or Company policy or practice, including the Employment Agreement, absent your execution of this Agreement. You also agree that the Severance Pay to be provided to you is not intended to and does not constitute a severance plan and does not confer a benefit on anyone other than the parties. You further acknowledge that, except for the specific financial consideration set forth in this Agreement, and your final wages, which shall be paid to you in accordance with the Company’s regular payroll practices and applicable law following the Separation Date (whether or not you sign this Agreement), you are not now owed and shall not in the future be entitled to any other compensation from the Company including, without limitation, other wages, commissions, bonuses, holiday pay, paid time off or any other form of compensation or benefit.

Equity. You acknowledge and agree that the disposition of Company equity in which you had an interest prior to the Separation Date will be fully governed by the terms of Section 2(b) of the Employment Agreement as they apply to terminations by the Company without Cause. You and the Company further acknowledge and agree that, at the time of the Separation Date, you owned 0 shares of common stock and had options to acquire an additional 490,000 shares of common stock, of which options to acquire 318,750 shares of common stock remain unvested and whose vesting will partially accelerate pursuant to Section 2(b) of the Employment Agreement.

Confidentiality. You expressly acknowledge and agree to the following:

a)       that you promptly will return to the Company all Company documents (and any copies thereof) and property (including, without limitation, all cell phones, pagers, storage devices, and other Company equipment) upon request, and the Company, for its part, will make reasonable accommodations to return copies of any personal data specifically requested by you and to return your personal belongings to you within two weeks of the Separation Date;

b)       that you promptly will relinquish to the Company all of the usernames, passwords, and contacts used by you to access all Sera and/or third party applications for your work with the Company;

c)       that your employment with the Company created a relationship of confidence and trust between the Company and you with respect to any information: (a) applicable to the business of the Company; or (b) applicable to the business of any vendor, broker, client or customer of the Company, which was made known to you by the Company or by any vendor, broker, client or customer of the Company, or learned by you in such context during the period of your employment. All such information has commercial value in the business in which the Company is engaged and is hereinafter called “Proprietary Information.” By way of illustration, but not limitation, Proprietary Information includes any and all trade secret, and proprietary information, techniques, know-how, processes, software programs, software source documents, and formulae related to the current, future and proposed products and services of the Company, and includes, without limitation, respective information concerning research, actual and proposed products and services, development, financial information, procurement requirements, purchasing manufacturing, customer lists, customer databases, customer policy information, business forecasts, sales and marketing plans and information. “Proprietary Information” also includes proprietary or confidential information of any third party who disclosed such information to the Company or to you in the course of the Company’s business. You acknowledge and agree that all Proprietary Information is the sole property of the Company, the Company’s assigns, and the Company’s customers (as applicable), and the Company, the Company’s assigns and the Company’s customers (as applicable) are the sole and exclusive owner of all copyrights, trade secrets and other rights in the Proprietary Information. You assign and agree to assign to the Company all rights, title and interest, you may have or acquired (if any) in the Proprietary Information. At all times, both during your employment by Company and after termination of such employment, you agree that you will keep in confidence and trust all Proprietary Information, and that you will not use or disclose any Proprietary Information or anything directly relating to the Proprietary Information without the written consent of the Company. You understand and agree that the terms of this Section extend to and cover disclosures or uses made of Proprietary Information online, including but not limited to social media sites, blog posts, and any other internet-based communication or posting forum.

d)       that all information relating in any way to the negotiation of this Agreement, including the terms and amount of financial consideration provided for in this Agreement, shall be held confidential by you and shall not be publicized or disclosed to any person (other than an immediate family member, legal counsel or financial advisor, provided that any such individual to whom disclosure is made agrees to be bound by these confidentiality obligations), business entity or government agency (except as mandated by state or federal law), except that nothing in this paragraph shall prohibit you from participating in an investigation with a state or federal agency if requested by the agency to do so;

e)       that you will not make any statements that are professionally or personally disparaging about, or adverse to, the interests of the Company (including its former or current officers, directors, employees and consultants) including, but not limited to, any statements that disparage any person, product, service, finances, financial condition, capability or any other aspect of the business of the Company, and that you will not engage in any conduct which could reasonably be expected to harm professionally or personally the reputation of the Company (including its former or current officers, directors, employees and consultants); and

f)        The Company agrees that it shall respond to third-party inquiries regarding your employment by providing only your period of employment and positions held and shall only verify your title and dates of employment and advise the requesting party that the Company has a policy of not providing any additional information regarding former employees.
