SELECT DISTINCT TOP(@PageCount) *
FROM (SELECT B.BusinessID,B.BusinessName, BT.BusinessTypeDesc AS BusinessType,BS.[Description] AS [Status],CONCAT(A.StreetAddress1,',',A.StreetAddress2,',',A.City,',',A.[State],',',A.Zip5,',',Zip4) as PrincipalOfficeAddress, B.EmailAddress,
    B.DateOfIncorporation
    FROM CORP.Business B WITH(NOLOCK)
    INNER JOIN CORP.BusinessType BT ON BT.BusinessTypeId = B.BusinessTypeId
    inner join [CORP].[BusinessXAddress] as BA on B.BusinessId=BA.BusinessId
    inner join [CORP].[Address] as A on BA.AddressId=A.AddressId
    INNER JOIN CORP.BusinessStatus BS ON BS.BusinessStatusId= B.BusinessStatusId
    WHERE (@BusinessID IS NULL OR B.BusinessID = @BusinessID)
    AND (@BusinessName IS NULL OR BusinessName LIKE '%' + @BusinessName + '%')
    ORDER BY B.BusinessID
    OFFSET @StartFrom ROWS)  as x
