Future adjustments in compensation, if any, will be made by Company in its sole and absolute discretion. This is an exempt position, which means you are paid for the job and not by the hour. Accordingly, you will not receive overtime pay if you work more than 8 hours in a workday or 40 hours in a workweek.

You will also be paid a one-time sign-on bonus of one-hundred thousand dollars ($100,000), less applicable tax and other withholdings (the “Bonus”), payable on the second regular payday following your start date. Company will pay you the Bonus in advance and in consideration of you having remained employed with the Company for a period of twelve (12) months after your Start Date (the “Retention Period”). Because Company is advancing the Bonus to you in anticipation of retaining your services for the Retention Period, in the event you should voluntarily resign your employment with Company for any reason or Company terminates your employment for cause, in either case prior to the end of the Retention Period, you agree to repay the Company the full amount of the Bonus within two weeks of your resignation of employment or termination for cause.

You will be eligible to participate in the Company’s 2023 Annual Performance Incentive Plan as it may be adopted and amended from time to time in the Company’s sole and absolute discretion. Your initial annual bonus target will be 50% of your base salary, which, to the extent earned, will be paid following the end of the calendar year. Eligibility and the amount of the bonus will be dependent on milestones and goals as set forth in the current bonus program. In addition, you must be employed by and in good standing with the Company at the time any bonus is paid in order to be eligible to receive a bonus.

You will also be eligible for all benefits available to other full-time Company employees, including medical, dental insurance, 401(k) plan, etc., in accordance with Company benefit plans. The Company reserves the right to change or eliminate these benefits on a prospective basis at any time.

In addition, we will recommend to the Board of Directors that you be granted an option to purchase 300,000 shares of Common Stock in accordance with the Company’s Stock Incentive Plan (the “Plan”) and related option documents. You will be required to sign the Incentive Stock Option Agreement (“the Agreement”) and the options will be subject to the terms and conditions of the Plan and the Agreement. The options vesting schedule is specified in the Agreement.



By accepting this offer, you represent that you are not a party to any other agreement which will interfere with your ability to fully and satisfactorily provide the services for which you are being employed by Company.

In addition, you agree that you will not disclose to Company, or induce Company to use, any confidential or proprietary information or material belonging to any previous employer or others. You agree not to enter into any agreement, whether written or oral, in conflict with your promises in this provision.

If you accept our offer, your employment with Company will be “at-will.” This means your employment is not for any specific period of time and can be terminated by you at any time for any reason. Likewise, Company may terminate the employment relationship at any time, with or without cause or advance notice. In addition, Company reserves the right to modify your position, duties and reporting relationship to meet business needs and to use its managerial discretion in deciding on appropriate discipline. Any change to the at-will employment relationship must be by a specific, written agreement signed by you and me at the time.

This offer is contingent upon the following:

SAN DIEGO, August 29, 2023 (GLOBE NEWSWIRE) — Telesis Bio Inc. (NASDAQ: TBIO), a leader in automated multi-omic and synthetic biology solutions, has named William J. Kullback as its Chief Financial Officer, effective August 28, 2023. As CFO, Kullback will be responsible for the Company’s financial planning and analysis, accounting, internal audit, tax, and treasury functions.

“Bill’s deep industry knowledge, operational expertise, and extensive financial experience make him ideally positioned to help lead us through the next phase of the Company’s growth,” said Todd R. Nelson, PhD, CEO, and founder of Telesis Bio. “We are thrilled to welcome Bill to our team and excited to have another leader who brings both a strategic and operational mindset to creating shareholder value as we deliver researchers the tools they need to rapidly and securely design, code, and create synthetic DNA and RNA.”

With more than twenty-eight years of experience as a Chief Financial Officer, Mr. Kullback has held a broad range of financial management and operational roles, primarily in mid-sized to large corporations, including multiple publicly held life-science companies.

Prior to joining Telesis Bio, Mr. Kullback served for five plus years as CFO of BioLegend, Inc., a worldwide provider of life science antibodies and reagents, where he led the company’s September 2021 sale to NYSE listed Revvity (formerly PerkinElmer) for $5.25 billion, the largest acquisition in PerkinElmer’s history.    

Before joining BioLegend in 2017, Mr. Kullback served as Chief Financial Officer of Lombard Medical, Inc. (Nasdaq: EVAR), a medical device company, from 2014 to 2017, prior to its acquisition by MicroPort Scientific Corporation, a Shanghai, China based medical device group. Similar CFO appointments at other medical device and technology companies have resulted in a host of successful transactions involving debt, M&A buy-side, M&A sell-side, and public offerings.

Mr. Kullback earned both his MBA and bachelor’s degree from the State University of New York at Buffalo.
