"The combination of the largest and second largest providers of per
diem nurse staffing will allow us to offer clients and healthcare
professionals an unparalleled level of service. We are equally excited
about the addition of InteliStaf's travel nurse staffing and vendor
management services business units, which will be highly complementary
to our core per diem nurse staffing business. This transaction will
enable us to offer a diverse range of quality staffing solutions to
healthcare organizations. The expertise contributed by InteliStaf's
management team and employees to the combined companies will enhance
our near and long-term market share and profitability objectives. The
acquisition is a significant fit with Medical Staffing Network's
current operations and creates an opportunity for us to increase the
scale of our operations and enhance our operating income."

joining the Medical Staffing Network team and believe that this
transaction will allow us to better meet the unique requirements and
expectations of our clients, healthcare professionals and
administrative personnel."

$155 million senior secured credit facilities consisting of a six-year
$30 million revolving credit facility, a six-year $100 million term
loan and a seven-year $25 million second lien term loan. These funds
