That is not the way regular expressions work in sed (or awk, ed, ex, or vi). The t*.* in tart*.*bank matches everything in red in the line:
Code:
tart*)*98'bank'ksb64bank)(tart2d&f44bank

Note that the RE you provided will also match tarxyzbank (with no "t" after "tar").

The following sed script seems to do what you want:
Code:
sed 's/bank/^Gbank/g
s/\(tart[^^G]*\)^Gbank/\1replaced/g
s/^G//g' input

Note that each time the sequence^Gappears in this script it needs to be replaced by a single character that can never occur in your input. I used an alert character (CTRL-G in ASCII), but you can use whatever you want in the above sed commands except for the <asterisk> (*), <backslash> (\), <circumflex> (^), <dollar-sign> ($), <left-square-bracket> ([), <period> (.) and <slash> (/) characters.

tart-custom(5)						     LinuxTaRT template format						    tart-custom(5)

NAME

       tart-custom - Template format for LinuxTaRT

DESCRIPTION

       LinuxTaRT  can  use  a  user  defined  template	file  to  generate  the signature.  The name and location of this file can be specified in
       ~/.tartrc, but defaults to the following location:

       ~/.tart-custom

PARAMETERS

       LinuxTaRT recognizes the following directives in the template and replaces them with the corresponding values:

       %c1 - CustomText1 from .tartrc

       %c2 - CustomText2 from .tartrc

       %tg - tagline
	      Randomly selected from the tagline database.

       %hr - horizontal line

       %dt - todays date
	      In the format: Monday, February 25, 2002

       %12 - current hour
	      12-hour format

       %24 - current hour
	      24-hour format

       %mn - current minutes

       %ap - AM / PM

       %ut - system uptime
	      For RiscOS or systems with the sysinfo function.

       %ib - time in ibeats

       %vi - LinuxTaRT version string

       %% - the percent symbol (%)

       Any other characters in the template are copied to the signature as is.

EXAMPLES

       The following template:

       LinuxTaRT - The Automatic Random Tagline
       %hr
       /dev/random says:
       %tg

       http://mycompany.com
       %hr

       Generates the following signature:

       LinuxTaRT - The Automatic Random Tagline
       -------------------------------------------------------
       /dev/random says:
       Best way to dispose of the Borg: Give them Windows 3.1.
