Need a formula to make Excel search for info

Please help! This would save me HOURS AND HOURS of work!

I need a formula to make Excel search columns C-E (all rows) of worksheet 1 for data contained in columns A-C of worksheet 2. If matching data is found, I want it to insert the data from column J worksheet 2 (same row as A-C) into column G of worksheet 1. I need to be able to apply the formula to each row, columns will remain the same.

Is this possible? I hope it makes sense, this is WAY beyond my Excel knowledge!

See attached for the worksheets.

Thanks in advance!
