Financial Highlights (for the 12 months to 31 March 2007)

-  Revenues increased to GBP31.1 million (2006: GBP17.7 million) with
   higher CytoFabTM, CroFabTM and VoraxazeTM revenues, offset by reduced
   DigiFabTM shipments to our US distributor

   including exceptional costs of GBP1.4 million) on CytoFabTM milestone
   and increased CroFabTM volumes

   GBP6.7 million) mainly due to increased investment in CytoFabTM and
   VoraxazeTM

-  General & Administrative ("G&A") expenses were GBP10.2 million (2006:
   GBP9.2 million) reflecting the increasing scale of the business,
   offset by benefits on foreign exchange positions and reduced share

   than market expectations

-  Strong cash position at end of period of GBP40.0 million (2006: GBP25.4

   GBP10.0 million milestone payment from AstraZeneca received after the
   financial year end.

   * GBP10.0 million milestone payment from AstraZeneca for the successful
     development of a large scale CytoFabTM manufacturing process

   * AstraZeneca to expand global clinical development programme for
     CytoFabTM in severe sepsis following positive discussions with
     regulatory agencies

-         VoraxazeTM:

   * Fast Track Designation granted by the Food and Drug Administration
     ("FDA")

   * Biologicals Licensing Application ("BLA") to be resubmitted in
     the US under a rolling submission starting in early 2008

   * FDA approval to charge for compassionate use supply in the US to
     help recover costs

   * Marketing Authorisation Application ("MAA") withdrawn in EU

   * Clinical programme initiated to support the repeated planned use
     of VoraxazeTM

-  Significant progress made with other development programmes.

Commenting on the results, Stuart Wallis, Chairman, said:

"This has been a year of good progress for Protherics as we expanded and diversified our portfolio of products. We expect to have nine clinical studies ongoing over the next 12 months and we see the data from these programmes as our biggest opportunity to deliver shareholder value in the near to mid term. With a strong cash position, a healthy pipeline and considerable activity across the business, we have good reason to look forward with confidence."
