Invoice product row price without tax

[Cadex]

File: app/code/local/Mage/Sales/Model/Order/Pdf/Items/Invoice/Default.php

            // draw Price
            $lines[$i][] = array(
                'text'  => $priceData['price'],
//                 'text'  => $priceData['price'],
                'feed'  => $feedPrice,
                'font'  => 'bold',
                'align' => 'right'

I want this row to come without tax. Why I'm modifying this is because I wan't product row subtotal is with tax and before it shows the tax amount. But I wan't to add excluding tax price as well.
