The proceeds of the Bonds will be used to make a loan to the Children’s Hospital (the “Borrower”). The loan will be used to finance, refinance or reimburse the Borrower for certain costs of: (1) the expansion, renovation, rehabilitation or equipping of healthcare facilities located at the Children’s National Hospital Sheikh Zayed Campus located at 111 Michigan Ave, NW, Washington, DC 20010 (the “Hospital”), which will include a 14 bed expansion of the Pediatric Intensive Care Unit at the Hospital, renovations to the Emergency Room at the Hospital, construction of a new Special Maternal Delivery Unit at the Hospital and the acquisition, development, and installation of the EPIC EMR (electronic medical record) and Billing system; (2) funding certain working capital costs, to the extent financeable relating to the Bonds; (3) funding interest on the Bonds and any credit enhancement costs, liquidity costs or debt service reserve fund relating to the Bonds; and (4) paying cost of issuance and other related costs to the extent permissible relating to the Bonds.
