It is understood that while OpGen will assign these contracts, such assignment is subject to approval by the respective customer counterparty.

Monthly consulting services and support contract of US $17,500 with OpGen Inc. for services to be provided in the maintenance of existing business, hand-over and transition of the US Unyvero business and customer accounts by Faranak Atrzadeh and Oliver Schacht. Such contract to start effective immediately and will be prorated for the month of April 2024.

After the end of June 2024, such services may be directly arranged between Curetis / Camtech and the individuals providing such services on a direct consulting or service contract basis.
