Pete, How do I make this only fill in the link only if RC[4] has someting there?

Code:
        For i = 6 To 82

        With Cells(i, 1)
        .FormulaR1C1 = "=HYPERLINK(""http://eic.mycom.com/eic_drw/qr/"" &RC[4],RC[4])"
        With .Font
        .Bold = True
        .Name = "Arial"
        .Size = 12
        .Underline = xlUnderlineStyleSingle
        .ColorIndex = 5
        End With
        End With
        Next
