Dear Sirs

Multi-Currency Overdraft Facility

I write to advise  the terms and  conditions  upon  which the Bank is willing to
make available to you a multi-currency overdraft facility.

1. Definitions

In this letter the following expressions shall have the following meanings:-

"Bank"  means The  Royal  Bank of  Scotland  plc  acting  as agent for  National
Westminster Bank Plc;

"Bank  Office"  means the office of the Bank at the above  address or such other
office/address as the Bank may notify to you from time to time;

"Facility" means the  multi-currency  overdraft facility made available or to be
made available on the terms and conditions set out in this letter;

"Facility  Accounts"  means  the  Sterling  Account  and  the  Foreign  Currency
Accounts;

"Facility Limit" means (pound)1,000,000;

"Foreign  Currency"  means any  currency  (including  the Euro)  which is freely
convertible into Sterling and readily available in the London Interbank Market;

"Foreign  Currency  Accounts" means the following  Foreign Currency  accounts on
which the Facility is made  available  (or such other  accounts as may be agreed
between us from time to time):- References: 140-01-06101445, 550-00-06854451;

"Gross Limit" means (pound)1,000,000;

"Sterling  " and the sign  "(pound)  " means the lawful  currency  of the United
Kingdom;

"Sterling Account" means the following Sterling account on which the Facility is
made available:-  Number:  01144642 at Portsmouth  Commercial Road (sorting code
560064);


2. Preconditions

The Bank will not be obliged to make the Facility  available until the following
condition(s) have been met:-

(a)  any new  security  required  has been  valued and  completed  to the Bank's
     satisfaction and the availability of any existing security for the Facility
     has been confirmed to the Bank's satisfaction;

(b)  you have accepted the Facility on the terms and  conditions set out in this
     letter by returning the  duplicate of this letter with the  acknowledgement
     duly signed, within 28 days of the date of this letter;


3. Limits and Utilisation

The Facility  may be utilised by  overdrawing  the  Facility  Accounts up to the
Facility Limit. The Facility Limit must not be exceeded at any time.

In  addition,  the  aggregate  of the cleared  debtor  balances on the  facility
Accounts must not at any time exceed the Gross Limit.

For the purposes of calculating the utilisation of the Facility:-

(i)  where  appropriate,  any creditor balances on the Foreign Currency Accounts
     will be netted against any debtor balances on the Foreign Currency Accounts
     in the same Foreign Currency; then

(ii) the  Sterling  equivalent  of the  net  balances  on the  Foreign  Currency
     Accounts shall be calculated by reference to the prevailing  market rate of
     exchange: and then

(iii)the  Sterling  equivalent  of the  net  balances  on the  Foreign  Currency
     Accounts will be netted against (or aggregated with) the net balance on the
     Sterling Account.

The Bank may decline to pay a cheque (or allow any other payment or  withdrawal)
from any Facility Account (whether in credit or debit) which would result in the
Facility  Limit  being  exceeded.  If the Bank does pay a cheque  (or allow such
other payment or  withdrawal)  resulting in the Facility Limit being exceeded it
will not mean either that the  Facility  Limit has changed or that the Bank will
agree to pay any other cheque (or allow any other payment or  withdrawal)  which
would have that effect.

The Bank may disregard any uncleared credits for the purposes of calculating the
utilisation of the Facility (and any interest payable). If however the Bank does
pay a cheque (or  allows any other  payment  or  withdrawal)  against  uncleared
credits this does not mean that it is bound to do so at other times.

4. Availability

(a)  The Facility is repayable  upon demand in  accordance  with normal  banking
     practice.


(b)  Without  prejudice to its overriding right to call for repayment on demand,
     it is the Bank's  present  intention  that the  Facility  will be available
     until 28 February  2006. The Facility will be reviewed on that date but may
     be extended by mutual agreement.

The Bank will always give  notification  of its intention to place a restriction
on your ability to make drawings on the Facility.

You may at any  time  advise  us in  writing  that  the  Facility  is no  longer
required.

5. Set Off, Retention and Appropriation

In addition to any other  rights to which it may be entitled,  including  rights
under any guarantee or security, the Bank may retain, set off or appropriate any
creditor  balances  (whether  current  or not yet due)  either  on the  Facility
Accounts  or any other  accounts  you may have with the Bank  against any debtor
balances on the Facility  Accounts,  or any other obligations you may owe to the
Bank whether present, future, actual or contingent.

The Bank may exercise any of these rights  without  prior notice both before and
after  demand and in so doing may convert to Sterling at the  prevailing  market
rate of exchange any balance which is in a Foreign Currency.

6. Interest

Sterling Accounts

Interest  will be  charged  by the Bank on the  cleared  debtor  balance  of the
Sterling Account as follows:-

(a)  on that part of the cleared  debtor  balance on the Sterling  Account up to
     (pound)1,000,000,  at a rate  equivalent  to 1.5% per annum over the Bank's
     Base Rate; and

(b)  for borrowing in excess of  (pound)1,000,000,  at a rate equivalent to 4.5%
     over the Bank's Base Rate.

Interest  will be  calculated  both  before and after  demand,  court  decree or
judgment on a daily basis and will be debited to the Sterling Account  quarterly
on the final  business day of March,  June,  September  and December (or on such
other dates as the Bank may advise from time to time).

The  Bank's  Base Rate may vary  from  time to time but as at 15 March  2005 was
4.75% per annum.  Changes  to the  Bank's  Base Rate may be made at any time and
with  immediate  effect,  such  changes  being  advised by way of press  notice.
Omission to publish details of any change in the press shall not stop the change
from taking effect.

Foreign Currency Accounts

Interest on any debtor balances on the Foreign Currency Accounts will be charged
separately by the Bank as follows:-

(a)  on that part of the debtor balance on each of the Foreign Currency Accounts
     up to  (pound)1,000,000,  at a rate  equivalent to 1.50% per annum over the
     Bank's relevant Currency Lending Rate; and


(b)  for borrowing in excess of (pound)1,000,000,  at a rate equivalent to 4.50%
     over the Bank's relevant Currency Lending Rate.

The Bank's  Currency  Lending Rates are variable and will therefore  change from
time to time.

Interest  will be  calculated  on a daily  basis and a year of 360 days (or such
other period as reflects market convention) on the debtor balance and debited to
the respective  Foreign Currency Accounts quarterly on the first business day of
March, June, September and December.

7. Costs

An  arrangement  fee of  (pound)1,850  is  payable  and will be  debited  to the
Sterling Account  following  receipt by the Bank of your acceptance of the terms
and  conditions  of the  Facility as set out in this letter or  following  first
utilisation  of the  Facility,  whichever  is the  earlier.  You  will  also  be
responsible  for paying any costs  incurred by the Bank in  connection  with the
Facility  whether as a result of you  breaking the terms of the Facility or not.
These costs will include (but not be limited to) costs of taking and discharging
any security; taking steps, including court action, to obtain payment; enforcing
and/or  preserving  the Bank's  rights under any security held for the Facility;
tracing you if you change address without notice and  communicating  with you if
you break the terms of the  Facility.  If such costs remain unpaid then they may
be debited by the Bank to any of the Facility  Accounts  (where  necessary after
conversion at the prevailing market rate of exchange).

8. Security

The Facility will be secured by the following:-

(a)  the existing available security held by the Bank as follows:-

     (i)  First Legal Charge by you over Industrial Unit at Site P3, Brunel Way,
          Segensworth Industrial Estate, Fareham, Hampshire;

     (ii) Debenture by you;

(b)  all further  available  security which the Bank may in future  obtain.  Any
     additional  security  will  require to be  granted in the Bank's  preferred
     form.  The value of the security will be reviewed  regularly  and,  without
     prejudice to its overriding right to call for repayment on demand, the Bank
     may seek additional security if there is a significant drop in the value of
     the security held.

9. Financial Information

To enable the Bank to monitor the Facility you will provide:-

(a)  as soon as they become available but in any event within 180 days after the
     end of your  financial  year,  your audited  financial  statements for that
     year; and


(b)  as soon as they  become  available  but in any event no later  than 21 days
     after the end of the  accounting  period  to which  they  relate,  and in a
     format   acceptable  to  the  Bank,   your  monthly   management   accounts
     incorporating  balance  sheet,  profit  and loss  account  and aged list of
     debtors and creditors (the "Management Accounts"); and

(c)  promptly,  such further information  regarding your financial condition and
     operations as the Bank may reasonably request.

All accounts  and other  financial  information  you provide to the Bank will be
prepared  consistently  and in accordance  with  generally  accepted  accounting
standards.

10. Financial Performance

The financial  statements  and  Management  Accounts will require to demonstrate
that on the last day of the period  covered by the relevant  statements/accounts
Overdraft   Utilisation  was  not  more  than  150%  of  Debtors  and  Overdraft
Utilisation  was not more than 250% of Debtors  plus stock minus  preferentials,
failing  which,  without  prejudice to the Bank's  overriding  right to call for
repayment on demand, the Bank, after due notice, may amend, restrict or withdraw
the facility.

For the purpose of this clause the following definitions shall apply:-

"Debtors"  means the value of  debtors  aged  less  than 90 days  excluding,  as
determined by the Bank, inter company  debtors,  debtors who are also creditors,
debtors in dispute or known to be doubtful, debtors domiciled outwith the United
Kingdom that are not credit  insured,  stage  payments due under  contracts  and
retention monies.

" Overdraft  Utilisation"  means the  aggregate  debtor  balance on the Facility
Accounts  as at the close of business  on the final  business  day of the period
covered by the financial statements or Management Accounts.

"Stock" is subject to retention of title  provisions,  obsolete  stock,  work in
progress and such other stock as the Bank may reasonably decide to exclude.

11. Miscellaneous

(a)  The Bank may debit any of the  Facility  Accounts  in  accordance  with the
     terms of Clauses 6 and 7 of this letter even if it results in the  Facility
     Limit being exceeded.

(b)  These  terms and  conditions  will not be affected in any way by any of the
     Facility  Accounts being  allocated  another  account number by the Bank or
     being transferred to another branch, office or department of the Bank.

(c)  The Bank may change any of these  terms and  conditions  by giving at least
     one month's written notice to you.

(d)  In the event of the Bank  demanding  repayment  of the Facility in terms of
     Clause 4 of this letter:-

     (i)  subject  to  sub-clause  (iii)  below,  you will  require to repay any
          debtor balances on Foreign Currency Accounts in immediately  available
          funds of the relative  Foreign Currency (or such other funds as may at
          the time  being  be  customary  for the  settlement  of  international
          banking transactions in such Foreign Currency);


     (ii) all payments  under the  Facility  will require to be made without set
          off or counterclaim and clear of any deduction,  whether of present or
          future taxes,  stamp duty or other charges  unless you are required by
          law to make such payment  subject to any deduction or  withholding  in
          which case the  relevant  payment  will require to be increased to the
          extent  necessary to ensure that the Bank  receives a sum equal to the
          sum which it would have  received  had you not been  required  to make
          such a deduction or withholding;

     (iii)the Bank reserves the right,  at any time after the serving of demand,
          to convert all or any balances on Foreign Currency Accounts  (together
          with any accrued interest and unpaid costs, charges, fees and expenses
          denominated  in such Foreign  Currency) to Sterling at the  prevailing
          market rate of exchange  and pass a  corresponding  debit  against any
          Sterling Account.

(e)  Unless  otherwise  agreed,  requests  for  new  Facility  Accounts  must be
     submitted  via the Bank Office at least 5 business  days in advance (in the
     case of Foreign  Currency  accounts,  using the relevant  application  form
     required by the Bank). The Bank's agreement to the addition (or removal) of
     Facility  Accounts  to/from the Facility will be subject to these terms and
     conditions being suitably amended to the Bank's satisfaction.

Please  indicate your  acceptance of the above terms and conditions by arranging
for the  acknowledgement  on the  duplicate  of this  letter  to be  signed  and
returned to me.

We may, at our option,  treat any usage of the Facility as  acceptance  (without
amendment) of the terms and conditions of this letter.

Please do not hesitate to contact me if you require  clarification of any of the
above terms and conditions.


Yours faithfully
For and on behalf of
The Royal Bank of Scotland plc acting as agent for National Westminster Bank Plc
