SQL 2005 Merging without the MERGE function

I am going to appologise in advance for how this question may come out but i will try and explain my best.

I have managed to produce a result set into a temp table which looks like the below.

col1          col2             col3           col4           col5
1             1                1              1             0
1             1                1              0             1
2             2                2              2             0
2             2                2              0             2

So in effect i would like col4 and col5 to read

col4            col5
1               1
2               2

as i am using sql 2005 i am unable to use a merge.

Please can someone advise what function would be best to use to get my desired out come.

Thank you in advance
