Magento how to Shopping Cart Price Rule exclude special price products？ -

i have created rule, when multiple products together, special price products discounted！

apply rule if following conditions met (leave blank products)

if of these conditions true :

if item found in cart of these conditions true:

special price less 0.01
special price date equals or less 2015-04-29

apply :percent of product price discount

discount amount :8

apply rule cart items matching following conditions (leave blank items)

if of these conditions true :
