Item 1.01 Entry into a Material Definitive Agreement.

On June 7, 2019, SINTX Technologies, Inc. (“SINTX”) entered into an Amendment to Centrepointe Business Park Lease Agreement (the “Lease Amendment”) with Centrepointe Properties, LLC (“Landlord”). The Lease Amendment amended certain terms of the original lease agreement entered into between the parties on April 21, 2009 (the “Original Lease”).

Pursuant to the Lease Amendment, the total leased space was reduced from approximately 54,000 square feet to approximately 30,000 square feet. Additionally, SINTX has agreed to promptly vacate from non-leased space (the “Vacated Premises”). Once Landlord confirms that SINTX has vacated from the Vacated Premises and the Vacated Premises are ready to be marketed by Landlord, the monthly rent due under the Original Lease will be decreased by $15,000. SINTX will continue to be responsible for the full previously leased space until the earlier of January 1, 2020 and the date a new tenant takes possession of the space vacated by SINTX. The term of the Original Lease was amended to end on December 31, 2024 and SINTX has two five-year extension options. Beginning January 1, 2020, the base rent is amended to be $16.74 per rentable square foot. On each one-year anniversary of January 1, 2020 thereafter, the amended base rent will increase by 3% of the immediately preceding prior year’s amended base rent. Notwithstanding the foregoing, if the Vacated Premises are leased by the Landlord and the new tenant begins paying rent for periods before January 1, 2020, the base rent for periods prior to January 1, 2020, will be reduced by the amount of rent paid by the new tenant for the Vacated Premises for periods before January 1, 2020.

The foregoing description of the Lease Amendment does not purport to be complete and is qualified in its entirety by reference to the full text of the Lease Amendment, a copy of which is filed hereto as Exhibit 10.1.

Item 8.01 Other Events.

A copy of the press release issued by the Company with respect to the Lease Amendment is attached hereto as Exhibit 99.1.
