I guess you are just going to get the 4th line.
The cat is not needed since sed can read files on it's own.

In bash you can do this
Code:
read VAR < <(sed '4!d' infile)
echo $VAR
test-9876

This should work in most shells and would also need no read:
Code:
VAR=`sed '4!d' infile`
echo $VAR

NAME
ul - do underlining SYNOPSIS
ul [ -i ] [ -t terminal ] [ name ... ] DESCRIPTION
Ul reads the named files (or standard input if none are given) and translates occurrences of underscores to the sequence which indicates underlining for the terminal in use, as specified by the environment variable TERM. The -t option overrides the terminal kind specified in the environment. The file /etc/termcap is read to determine the appropriate sequences for underlining. If the terminal is incapable of underlining, but is capable of a standout mode then that is used instead. If the terminal can overstrike, or handles underlining automati- cally, ul degenerates to cat(1). If the terminal cannot underline, underlining is ignored. The -i option causes ul to indicate underlining onto by a separate line containing appropriate dashes `-'; this is useful when you want to look at the underlining which is present in an nroff output stream on a crt-terminal. SEE ALSO
man(1), nroff(1), colcrt(1) BUGS
Nroff usually outputs a series of backspaces and underlines intermixed with the text to indicate underlining. No attempt is made to opti- mize the backward motion. 4th Berkeley Distribution May 7, 1986 UL(1)
