Here is simple solution:

#!/usr/bin/perl 

my @tmp1 = 
    map { chomp; [ split /\s+/, $_, -1 ] }
    `cat tmp01`;   # (*)

my %tmp2 = 
    map { 
        chomp; my @a = split /\s+/, $_, -1; 
        ($a[0], \@a) 
    }
    `cat tmp02`; 

print join "\t"
    @$_, 
    @{ $tmp2{$$_[0]} }, 
    "\n" 
for
    @tmp1; 

# (*) instead of `cat tmp01` it is more safe to: 
#use Path::Tiny; 
#path("tmp01")->lines_utf8({chomp => 1});
