Question : Exclude if Is Not Null

Query works fine except now I need to exclude records if there is any date in Data.EarlyOut field.

SELECT [Last Name] & ", " & [First Name] AS Name, Data.EarlyOut, Data.EndContract, Data.[Email Address], Data.PersonnelID, Data.[Completed Extension]
FROM Data
WHERE (((Data.EarlyOut) Is Null) AND ((Data.EndContract) Between [Forms]![Extension Query]![txtStartDate] And [Forms]![Extension Query]![txtEndDate])) OR (((Data.EarlyOut) Between [Forms]![Extension Query]![txtStartDate] And [Forms]![Extension Query]![txtEndDate]));

Thanks,
