Date: November 12, 2021 To: HR Department Subject: Resignation Letter Sir/ Madam, I would like to inform you that I have decided to take this time to change my career path and have resolved to render my resignation as Process Engineer effective on November 19, 2021. I regret any inconvenience that this will cause. This decision has nothing to do with the opportunities you have provided me here. I appreciated everything the company and co-employees have done to train me as a Process Engineer. I hope that Ibiden Philippines Inc. will continue its every success in the coming years. Thank you and Godbless. Respectfully Yours, Lhoyd Petate Process Engineer Acknowledged by: Shiellah Mae Silva Senior Process Engineer Vener Unigo PE Group Manager
