La Jolla, CA December 23, 2003 - Viking Systems,  Inc. (VKSY:PK) today announced
that it has  agreed  to  acquire  the  assets  of the  visualization  technology

stock in Viking,  royalties and other cash payments. This transaction is subject
to the approval of Vista Medical's stockholders:  if approved, it is expected to
close in the second half of January,  2004. Over a five year period, the royalty
and cash payments will range between a minimum of $1,475,000  and an approximate
maximum of $5,500,000,  dependent on the  performance  of the acquired  business

Technologies  will be a good platform for our visualization and surgical control
effort.  We are excited  about this  technology  and look forward to growing the
business,  both for laparoscopic  bariatric  surgery and other complex minimally
invasive surgical applications."
