                     Stem Cell Sciences plc (the "Company")


On 2 November 2005 the Company granted an option (the "Option") to subscribe for
280,000 Ordinary Shares of 50p each in the capital of the Company ("Ordinary
Shares") to Brandon Capital Management Pty Limited ("Brandon").

The exercise price for the exercise of the Option is 97p per Share and the
Option is exercisable by Brandon on or prior to 22 October 2008.  The Option is
transferable only with the prior written consent of the Company.

The Option is being granted at the request of Australian Biotechnology and
Healthcare Fund No.3 Limited ("ABHF"), an existing option holder and shareholder
of the Company.  On 23 June 2005 ABHF was granted an option to subscribe for
280,000 Ordinary Shares at an exercise price of 50p per share and the Option is
only being granted to Brandon on the basis that ABHF is surrendering its right
to exercise its existing option to subscribe for Ordinary Shares.

ABHF is subject to an Orderly Marketing Agreement whereby they have undertaken,
subject to certain limited exceptions, to sell Ordinary Shares through Collins
Stewart Limited (or such other broker appointed by the Company from time to
time) provided the Company's broker offers market terms for the carrying out of
such sale for a period of year ending on 18 July 2006.

Brandon is subject to an Orderly Marketing Agreement whereby they have
undertaken, subject to certain limited exceptions, to sell Ordinary Shares
through Collins Stewart Limited (or such other broker appointed by the Company
from time to time) provided the Company's broker offers market terms for the
carrying out of such sale for a period ending on 18 July 2006.

Following the lapse of the ABHF's option to subscribe for 280,000 ordinary
shares of 50p each (referred to above) ABHF will be interested in 560,000
Ordinary Shares representing approximately 2.51% of the issued share capital of
the Company and Brandon will be interested in 280,000 Ordinary Shares
representing approximately 1.25% of the issued share capital of the Company.
