                            PRELUDE PORTFOLIO UPDATE


                    News from Kiadis Pharma and DisplayLink.


Prelude Trust plc ("Prelude" or "the Trust"), the investment trust specialising
in high growth technology-based businesses and managed by Esprit Capital
Management Ltd ("DFJEsprit"), is pleased to announce the recent progress of two
of its portfolio companies, Kiadis Pharma, the oncology product development
business and DisplayLink the networked display company.


Kiadis Pharma ("Kiadis")


Kiadis has successfully completed a Phase II clinical trial evaluating its
product Reviroc(TM). Reviroc is used to eliminate cancer cells from an autologous
graft in bone marrow transplantations for end-stage blood cancer patients. An
autologous transplant uses the patient's own bone marrow to serve as the
material that is transplanted. Reviroc was designed to specifically elimininate
cancer cells from a patients bone marrow. This allows the reinfusion of a
"clean" transplant devoid of any cancer cells back into the patient. Data from
the clinical study revealed improved overall survival of Reviroc-treated
patients. This successful completion of the clinical trial allows Kiadis to move
on to a Phase III clinical study.


Commenting on the completion of the trial Manja Bouman CEO of Kiadis said: "We
are very pleased with the completion of this Phase II trial of Reviroc. It
brings treatment with our product a step closer to patients with end stage blood
cancer. Reviroc shares its development platform with two other Kiadis Pharma
products: ATIR and Rhitol. The results of this trial therefore mark an important
milestone in the development of our entire clinical product pipeline."


Prelude currently has a 6.3% shareholding in Kiadis Pharma.

DisplayLink


DisplayLink have announced that Toshiba has chosen its high-performance
networked display technology for the Dynadock family of universal laptop docks.
The product made its debut at IFA Berlin (the international consumer electronics
forum).


The Toshiba Dynadock is an advanced universal docking station that can be used
with any Windows XP or Vista notebook PC with a USB 2.0 port. It allows a
consumer to connect a notebook to a monitor, network cable and up to six USB
peripherals with a single USB 2.0 connection.

One Dynadock model is based on the DisplayLink DL-160 chip and supports
DVI-based Widescreen Super Extended Graphics Array - WSXGA+) or Ultra Extended
Graphics Array - UXGA displays. The result is a crisp digital output even for
notebooks without built-in digital monitor support, providing a cost-effective
way to use a standard notebook in these applications.

Prelude currently has an 11% shareholding in DisplayLink.

Notes to Editors


About Reviroc

Reviroc is being developed as a treatment that eliminates blood cancer cells
from autologous transplants for patients with end stage blood cancer. An
autologous transplant uses the patient's own bone marrow to serve as a graft.
Bone marrow transplantations are broadly recognized as a treatment option for
patients suffering from blood cancers, such as leukemia and lymphoma. Reviroc
has been developed to remove residual tumour cells from the graft.


About DisplayLink Network Display Technology

DisplayLink technology is comprised of the DL-120 and DL-160 high-performance
network display chips and Virtual Graphics Card (VGC) software that powers
high-quality, fully interactive 32-bit true-color graphics with real-time video
playback across a USB link. They are designed for monitor manufacturers, PC OEMs
and PC accessory companies who want to develop easy to use high performance
products such as USB-connected monitors, video-capable USB laptop docking
stations, Skype video phones, picture frames and other devices. The company's
lossless compression algorithm and adaptive graphics protocol can also transmit
graphics over other standard network interfaces, including wireless USB,
Ethernet or Wi-Fi.
