"As we continue to make progress and further our plans for the transformation of Catalyst to a
company developing novel prescription drugs to treat rare neurological diseases, we felt that it
was important to upgrade and revamp our website," said Patrick J. McEnany, Chief Executive Officer
of Catalyst.

About the Website

The site provides an information platform for patients, physicians and investors in an easy to
navigate format.

The aim of the site is to allow visitors to gain a comprehensive understanding of the Company's
drug candidates. Patients and other interested parties can learn about Catalyst's drug candidates,
related clinical trials and the science behind them. Website visitors will have an ability to
follow the progress of the drug candidates and Company's development in the News and Events
sections. Current and potential investors will have the ability to download the latest information
on the Company in the Investors section.

In keeping with Catalyst's mission to provide treatment for rare neurological diseases through
collaboration with patients, physicians, scientists and other constituencies, the new website also
offers multiple ways of contacting the Company. All the inputs will be carefully reviewed and will
serve as a basis for further development of the website. The ultimate goal is to eventually expand
the website into a forum for patients, physicians and other stakeholders to share information,
ideas and recommendations.
