Montréal, December 8, 2020 – Bold Capital Enterprises Ltd. (“Bold”) (TSX-V Bold) and Dymedso Inc.
(“Dymedso”), a Montréal-based medical technology company, are proud to announce that 12 healthcare
institutions in the Province of Québec are now permitted to provide their patients with the benefits of a
new, state-of-the-art device that uses acoustic sound waves for the treatment of lung disorders and
respiratory infections, including those related to COVID-19.

The distribution of 24 airway clearance devices, known as the Frequencer®, to Québec healthcare
institutions, was made possible through a non-refundable contribution thanks to a partnership with
Québec’s Ministère de la Santé et des Services sociaux and Ministère de l’Économie et de l’Innovation, as
part of the Innovation Program – Support for Demonstration and Technology Showcase Projects.
Dr. Simon Phaneuf, emergency physician and Chief Scientific Officer at Dymedso, pointed out, “Clinical
advances show that non-intrusive treatments, such as the acoustical wave treatment provided by the
Frequencer, increase the medical success rate and significantly reduce the risk of complications for
patients.” He added, “As Québec experiences an increase in hospitalizations related to the COVID-19
virus, the use of the Frequencer in healthcare settings should be an integral part of an effective and safe
treatment that contributes to saving lives. All medical institutions should equip themselves with the
Frequencer device’s advanced technology with the objective of constantly improving treatments for
COVID-19.”

Entirely developed in Québec, the Frequencer® is a patented technology that uses acoustic sound waves
to clear the airways and promote bronchial drainage, acting on both the lungs and its deep-seated
airways where mucus collects. This form of pulmonary physiotherapy offers a non-invasive alternative to
percussion (“clapping”) techniques for patients of all ages suffering from respiratory problems associated
with mucus accumulation in the lungs, including COVID-19-related infections. The device enables
preventive and targeted treatment that can be concentrated in the most affected areas of the lungs,
reducing the risk of complications. The Frequencer has been cleared by Health Canada and the U.S. Food
and Drug Administration (FDA). Dymedso also holds the CE mark in Europe.

The device was designed to be used at home and in a variety of care settings, including hospitals, long-
term care centres (CHSLDs), private senior residences and rehabilitation centres.

“The health crisis offers an opportunity for our companies to showcase their expertise in several strategic
areas, such as life sciences. This project, supported by our government, will make it possible to optimize
the quality and efficiency of care offered in our healthcare institutions, thanks to leading-edge
technologies. Québec must remain attractive and competitive. It is by relying on creative and innovative
companies like Dymedso that we will succeed,” said Pierre Fitzgibbon, Minister of the Economy and
Innovation.

Kim Anderson, President of Dymedso, stated, “The technology developed by Dymedso has been proven
effective in treating patient lungs impacted by mucus, both here in Canada and around the world, and
we are pleased to be able to extend its use in these healthcare facilities throughout the province. During
this global pandemic, we are proud to make available Dymedso’s cutting-edge pulmonary physiotherapy
treatment for the benefit of these very vulnerable patients, and at the same time contribute to the
advancement of science in the treatment of lung infections.”
This initiative is in keeping with Dymedso’s goal of expanding the use of the Frequencer to numerous
healthcare institutions in Québec and Ontario, in addition to continuing its rollout internationally. The
device is currently used in 53 countries, including at several world-renowned university hospitals in
California, Europe and Kuwait.

The Frequencer has been sent to the following 12 healthcare facilities across the province:
Centre hospitalier universitaire Sainte-Justine, McGill University Health Centre, Glen site, McGill
University Health Centre, Montreal General Hospital, Hôpital de Verdun, Hôpital Sacré-Cœur, Hôpital de
Saint-Jérôme, Hôpital Charles-Le Moyne, Hôpital Pierre Boucher, Hôpital Honoré-Mercier, Hôpital de
Gaspé, Hôpital de Chicoutimi, CHSLD Monseigneur Ross (Gaspé).
