The Board of Directors of Xtant Medical Holdings, Inc. (the “Company”) appointed Michael Mainelli as Interim Chief Executive Officer, replacing Carl D. O’Connell, effective October 12, 2018.

Mr. Mainelli, age 57, has served as a member of the Board of Directors of the Company since February 2018. Mr. Mainelli was initially elected to the Board in connection with the Company’s restructuring in February 2018. Mr. Mainelli has worked in the medical device industry for over 25 years, serving the diagnostic imaging, surgical, and orthopedic markets. He has extensive international experience having led operations in Japan, France, the United Kingdom and Israel. From March 2013 to May 2016, Mr. Mainelli served as President and Chief Executive Officer of Stanmore Implants Worldwide, LTD, a UK based specialty orthopaedics company, and led the sale of the company to Stryker Corporation. From 2008 to 2011, Mr. Mainelli was the President and Chief Executive Officer of Active Implants Corporation, an early stage company developing an innovative meniscal implant. From 2005 to 2006, he was the Group President of the Medical Device Segment of Intermagnetics General Corporation before the company was acquired by Royal Philips. Mr. Mainelli was with Stryker Corporation serving in the positions of VP-Corporate Development, Assistant to the Chairman, President-Stryker Japan and President-Stryker Spine. Prior to Stryker, he was employed by General Electric in various management roles. He has previously served on the board of directors of Orthofix International N.V., a publicly traded medical device company, Active Implants Corporation and Stanmore Implants Worldwide, LTD, which were venture capital backed privately-owned companies. He currently serves on the board of directors of Autocam Medical Devices, LLC, a privately-owned medical device contract manufacturing company. He earned a MBA from the University of Chicago, a Master of Science in Engineering from the University of Pennsylvania and a BS in Mechanical Engineering from Northeastern University.

In connection with Mr. Mainelli’s appointment as an interim officer of the Company, the Company entered into an interim executive employment agreement and stock option award agreement with him. Under the terms of the employment agreement, Mr. Mainelli will be paid an annual base salary of $525,000 and will be eligible to receive an annual bonus with a target bonus opportunity equal to 75% of his annual base salary. In addition, effective October 15, 2018, the Company granted him an option to purchase 240,000 shares of the Company’s common stock under the Xtant Medical Holdings, Inc. 2018 Equity Incentive Plan (the “Plan”). The option has a 10-year term and a per share exercise price equal to the “fair market value” (as defined in the Plan) of the Company’s common stock on the grant date. The option will vest with respect to 10,000 of the underlying shares on a monthly basis and will discontinue vesting in the event Mr. Mainelli no longer serves as the Company’s Chief Executive Officer, on either an interim or permanent basis. In the event of a “change in control” of the Company (as such term is defined in the stock option award agreement), the option will immediately vest with respect to an additional six months. The employment agreement also contains standard confidentiality, non-competition, non-solicitation and assignment of intellectual property provisions.

The Company has entered into an indemnification agreement with Mr. Mainelli which may require the Company, among other things, to indemnify Mr. Mainelli for expenses, judgments, fines and amounts paid in settlement incurred by him or on his behalf in connection with any proceeding arising out of his service as a director or officer of the Company, or any of its subsidiaries or any other company or enterprise to which he provides services at the Company’s request.

In connection with Mr. O’Connell’s departure, the Company intends to enter into a standard and customary separation agreement and release with Mr. O’Connell pursuant to which the Company will agree to provide him certain severance benefits as provided in his Employment Agreement effective as of October 6, 2016, as amended, contingent upon his execution, delivery and non-revocation of a release of claims against the Company and its subsidiaries and affiliates and compliance with certain covenants contained therein.
