 of
our research and development costs have been external expenses. We utilize third party contractors for our research and development activities.
We track these external expenses on an individual program basis within our portfolio, when they are specific to an individual program,
once a clinical product candidate or program has been identified.

We use CMOs for our manufacturing
activities and we do not have our own laboratory or manufacturing facilities. Therefore, we have no material facilities expenses attributed
to research and development. We track our manufacturing activities on a portfolio basis when we have multiple programs in a portfolio,
but do not track these activities on a program basis within the portfolio, as these costs are deployed across multiple programs within
a portfolio.

Our internal research and
development costs are primarily personnel-related costs. We do not track internal costs on a portfolio or program specific basis because
these costs are deployed across multiple programs and, as such, are not separately classified.
