Where Caluse In Join

Select c.Planid, c.Claim, c.mon,c.Ho,c.ES,c.FactorType,m.DOD, 0

from tbFLags c inner join tbMembers m

On c.Claim = m.HicNumber

where c.Planid = '91' and c.Pay = c.mon and c.= '2006-12-01 00:00:00' and (c.Hp<>'1'

or c.ES <>'1' or c.FactorType not in ('D', 'I1', 'I2')

or m.DOD IS NULL )

What I am trying to get in the above example is to exclude some of the rows from select in the where caluse.
so if either one of these are not hp<>'1' or ES<>'1' or FactorType not in ('d', 'l1', '12') or dod is not null) should not be include in the select.

so HP should not be equal to 1, ES should not be equal to 1 or factortype no in d l1, or 12 or dod is null.
but some how I am getting those recrods where HP is 1 or ES is one and even dod is not null .

someone help please
