             MIRAVANT OBTAINS $15 MILLION CONVERTIBLE LINE OF CREDIT

SANTA BARBARA,  Calif.,  March 8, 2005 - Miravant Medical  Technologies  (OTCBB:
MRVT),  a  pharmaceutical  development  company  specializing  in  PhotoPoint(R)
photodynamic therapy (PDT),  announced today that it has finalized a convertible
debt  line-of-credit  agreement  for up to $15.0  million  with a  long-standing
Miravant  investor.  The funds will be available at the Company's  discretion in
increments of up to $1.0 million per month,  with any unused monthly  borrowings
to be carried  forward.  The  borrowings are  convertible  into shares of Common
Stock based on a premium of 110% of the  average  monthly  closing  price of the
month preceding each borrowing request. Additionally, we will issue a warrant to
purchase  one-quarter of a share of Common Stock for each  convertible  share of
Common Stock  issued.  The exercise  price of each warrant will also be equal to
110% of the average  monthly  closing price of the month preceding the borrowing
request.

Gary S. Kledzik,  Ph.D.,  chairman and chief executive officer,  stated, "We are
very  pleased to secure this  financing  to support our  PhotoPoint  development
programs.  This  line  of  credit  will  provide  funding  for  the  PHOTREX(TM)
confirmatory phase III clinical trial for age-related macular  degeneration,  in
which we expect to begin patient enrollment next quarter."

Additional  information  about the terms of the convertible  debt line of credit
agreement is contained in the Company's Form 8-K to be filed with the Securities
and Exchange Commission no later than March 10, 2005.
