The two bars, along with nightclub Mission, collapsed into administration on July 31 owing to pressures from Covid-19.
A spokesperson for the three companies said that a deal had been struck to save 102 Jobs at Bar Fibre and Viaduct Leisure.
However Mission has not been saved and will close.
A spokesperson for the three companies said: "Due to extraordinary circumstances related to COVID-19, Bar Fibre Limited, Viaduct Leisure Limited and Mission (Leeds) Limited sadly all went into administration on the 31st July 2020.
"Fortunately, we are pleased to have been able to save 102 jobs at Bar Fibre Ltd and Viaduct Leisure Ltd. Unfortunately, Mission couldn't be saved. The night time industry sector has suffered the most through the pandemic, with social-distancing measures being an anathema to the nightlife industry. We hope the government extends support for the sector into 2021 to ensure it's long term survival."
