NxStage + One™ Meeting

NxStage Medical, Inc.’s innovative initiative, NxStage + One, is a
patient-to-patient outreach program designed to offer peer support, education
and awareness for those living with chronic kidney failure.   At this lunch meeting, NxStage patients and
care partners will have the opportunity to meet other NxStage home dialyzors, share
their experiences using the NxStage System One™, and test their knowledge on vascular access care.

NxStage
+ One aims to empower thousands of the Company’s patients to share their
stories with at least one other ESRD patient in the hopes of increasing
awareness for HHD and access to the benefits possible with this therapy.

The event is free to attend and NxStage patients can RSVP to Mary
Scourick by emailing mscourick@nxstage.com or calling (978) 687-4887.
