SEEK: PepTcell Changes Name due to New Focus and Success

LONDON, December 1, 2010 - PepTcell, a leading UK privately-owned drug-discovery group, today
announced it is changing its name to SEEK.

Gregory Stoloff, Chief Executive Officer, explains: "SEEK has
a significant number of potential blockbuster assets in different legal
entities and we wanted to give them a common identity and purpose. Announcing
a simple and uniting group brand name, SEEK, reflects our efforts to 'seek a
cure' in a number of major disease areas."

SEEK has a leading innovative mid-to-late stage portfolio of
breakthrough treatments. Entering Phase III trials are a first-in-class cough
suppressant, with a clinically-proven efficacy and safety profile, and a
small-molecule drug for inflammatory flare, with a clinically-proven safety
analgesic profile. In the area of vaccination, SEEK has made significant
progress with a universal flu vaccine - intended to be effective against all
strains of flu virus, eliminating the need for annual flu vaccinations - and
an HIV vaccine, both completing Phase Ib/II clinical trials.

The name change is effective as of 1st December 2010. In
parallel with this name change, SEEK has launched a new corporate website:
www.seekacure.com.

SEEK - A growing and diversifying company

SEEK began life in 2004 as an immunology company, quickly
establishing a new vaccine-technology platform with a focus on peptide-based
T cell vaccines (based on a novel understanding of the molecular level
interactions between immune cells). Lead products under this platform are a
Universal Flu and an HIV vaccine, with Phase Ib/II clinical trial data due
early and mid-2011. Vaccines for mosquito-transported and chagas diseases are
in the pre-clinical phase, with Hepatitis B & C and rotavirus vaccines in
research.

Recent acquisitions have also provided the group with chemical
biology and target-identification expertise. Coupling these competencies with
SEEK's immunology and regulatory knowledge, has resulted in two drugs
entering Phase III clinical trials; one for the treatment of persistent cough
and the second for the treatment of pain, inflammation and auto-immune
diseases.

Stoloff says: "With our expanding therapeutic focus and
continued successful growth, we felt that now was the time to reposition the
group to ensure our investors, collaborators and partners understand our long
term goals and how we are working to achieve them. "
