VBA to delete rows

I am trying to write a macro that deletes rows based on certain criteria. I have rows with the word "Summary:" in it that I want to keep (no problem). My issue is that i then have rows that all begin with "Application:". What comes after that is different (i.e. Application: Start, Application: End). I need help creating this wildcard search as I have tried with no succes. This is what I have so far:

Sub A()
Set objExcel = CreateObject("Excel.Application")
objExcel.Visible = True

Set objWorkbook = objExcel.Workbooks.Open("C:\Documents and Settings\MANNM4\Desktop\Copy of appt center (dec 2009)-test")
i = 1

Do Until objExcel.Cells(i, 1).Value = "Done"
    If objExcel.Cells(i, 1).Value <> "Summary:" And objExcel.Cells(i, 2).Value <> "Offered" Then
        Set objRange = objExcel.Cells(i, 1).EntireRow
        objRange.Delete
        i = i - 1
    End If
    i = i + 1
Loop

End Sub
