We are obligated to reimburse Emory University (a significant stockholder of the Company) for ongoing costs in connection with the filing, prosecution and maintenance of patent applications subject to a license agreement for technology associated with the vaccines we are developing.

In connection with our IPCAVD grant from the NIH (see Note 5), we entered into subcontracts with Emory for the purpose of conducting research and development activities related to the grant.

All amounts paid to Emory under these subcontracts are reimbursable to us pursuant to the NIH grant.
