"Accordingly, the Company expects to start filling initial sales orders it has received from existing pharmaceutical customers for the Unifill syringe by late-June 2011"

Unilife has also received requests from a number of other interested pharmaceutical companies for the Unifill syringe as part of ongoing discussions. It is expected that these pharmaceutical companies will purchase the initial production batches to undertake formal evaluations of the device prior to the signing of any commercial agreements with Unilife.

Note that customers is plural in the first paragraph and is seems they already have other customers lining up for a looksie too, albiet not signed up under a formal agreement, as yet.
