Manuel Pablo Zuniga-Pflucker, President and Chief Executive Officer, commented:

"We are very appreciative of the guidance and support provided by Gran Tierra and certainly wish them success in their continued corporate growth. The Peruvian assets and start-up funding provided by Gran Tierra when PetroTal was created in late 2017, formed the nucleus for PetroTal's growth.

Additionally, we are excited to welcome Remus as PetroTal's largest shareholder. The long term investment focus, along with sound business and social principles of the fund, will provide solid backing for PetroTal. All stakeholders in the Company will benefit from knowing our shareholder base is strong and committed to PetroTal's ongoing growth."

Gary Guidry, President and Chief Executive Officer of Gran Tierra, commented:

"As part of our ongoing commitment to a disciplined financial strategy, with a focus on balance sheet protection and long-term value preservation, we decided to sell the majority of our PetroTal Shares.

Manolo Zuniga and the entire team at PetroTal have done an excellent job developing the Bretana oil field in Peru and navigating through these very challenging and volatile times in the industry. With a strong board and executive management team in place, PetroTal is positioned to add value for many years to come."

Sath Kanagarajah, Chief Executive Officer of Remus Corporation commented:

"We are delighted to achieve this significant strategic milestone for Remus and our investors.
