                                   SCHEDULE
                    Amendments to the Facilities Agreement

With effect on and from 31 December 2003, the Facilities Agreement shall be
further amended as set out in this Schedule. All references in this Schedule
to clause numbers are references to clauses in the Facilities Agreement and
all references to paragraph numbers are references to paragraphs of this
Schedule.

1. The definition of "Adjusted Tangible Net Worth" in Clause 1.1 of the
Facilities Agreement shall be amended by the addition of the following

         a) to the end of the first paragraph of such definition:-

                  "as determined in accordance with GAAP"

         b) to the end of the last paragraph of such definition:-

                  "provided that no such addition, deduction, exclusion or
                  adjustment shall be made if it arises or relates to any
                  event occurring on or prior to 31 December 2003."

2. Clause 7.1.1 of the Facilities Agreement shall be deleted in its entirety
and replaced with the following new clause 7.1.1:-

                  "7.1.1   the principal amount of the Term Facility in the
                           following manner:

                           starting on 31 January 2004 and then at
                           the end of every month thereafter through
                           and including 30 April 2006, (pound)90,000
                           each month in arrears, with a final
                           payment of (pound)1,348,750 on 21 May 2006."

3. The existing Clause 9.3.2 (Adjusted Tangible Net Worth) contained in the
Facilities Agreement, as amended, shall be amended by the replacement of the
figure "(pound)8,500,000" in the final row of column C with the figure
"(pound)4,600,000". For the avoidance of doubt, the effect of this amendment
is such that the Borrower undertakes to the Bank that Adjusted Tangible Net
Worth will not be less than (pound)4,600,000 on 31 December 2003 and
thereafter.

4. The first paragraph in the existing Clause 9.3.1 contained in the
Facilities Agreement, as amended, shall be deleted in its entirety and
replaced with the following new paragraph:


         The ratio of Consolidated EBITDA to Consolidated Fixed Charges as at
         31 March, 30 June, 30 September and 31 December in each year
         following 2003 shall not be less than 1 to 1. Such ratio shall be
         measured for the 12 months ending on such dates on a rolling basis
         except that such ratio as at 31 March 2004, 30 June 2004 and 30
         September 2004 shall be measured for the 3, 6 and 9 months,
         respectively, ending on such dates. For the avoidance of doubt, the
         first test date for this covenant shall be 31 March 2004.
