on account number 11119338 on the following terms and conditions.

Amount

The maximum aggregate amount outstanding under the facility at any time (calculated on the basis of cleared funds) shall not exceed US$3,000,000.

Availability

The Bank's present intention is to make the facility available until 31stDecember 2003 and all moneys from time to time owing to the Bank
under the facility shall be repaid no later than this date or such later date as may from time to time be advised in writing by the Bank. The Bank may, nevertheless, terminate the facility at any time
and may at such time or at any time thereafter demand immediate payment of all amounts owing under or in connection with the facility. The amounts owing at to any time may include interest costs or
charges which have been debited to the account in accordance with the terms of this letter.

The
bank shall have the right at the time of making demand or at any time thereafter to convert all amounts due and payable in US dollars into sterling at the Bank's exchange rate for
selling that currency against sterling at that time. The Bank shall as soon as possible after such conversion advise you of the sterling amount then owing.

Interest

Interest is calculated on the cleared daily balance of the account and will be payable on amounts owing up to the aforesaid limit at 1.75% per annum over the
Bank's short term offered rate from time to time for US dollars.

---

If
at any time the Bank allows the amounts owing to exceed the agreed limit interest will be payable on the excess at the Bank's unauthorized currency borrowing rate from time to time
(currently 12% per annum above the Bank's short term offered rate) for US dollars.

Interest
will be debited to the account quarterly in arrears (normally on the 24th of each February, May, August, and November or on the next working day). Interest
may also be debited on the date upon which the facility ceases to be available.

The
Bank's short term offered rate for US dollars may vary from day to day and upon request the Bank will advise you of the rate then applicable.

Interest
will be calculated on the basis of the actual number of days elapsed and a 360 day year.

Costs and Charges

Account transaction charges will be payable on the account quarterly in accordance with the Bank's Standard Business Tariff a copy of which has already been
provided to you. We will be pleased to forward a further copy of the tariff leaflet if one is required. In addition further charges will be payable for other services provided as shown in the tariff
leaflet or as otherwise advised by the Bank from time to time.

These
charges will be debited to the account and may be varied by the Bank at any time and notice of changes will be advised to you.

An
arrangement fee of $22,500 is payable. This will be debited to account number 11119338 in two installments being $17,500 in the next few days and $5,000 in June 2003 or
shortly thereafter.

All
costs and expenses incurred by the Bank in preserving or enforcing the security referred to below shall be debited to account number 01232434 under advice to you.

Security

It is a condition of the facility (and of the other facilities referred to below) that amounts owing shall be secured by the following:



The
Bank holds a letter of set off dated 24th April 1996 completed by the Company.

It
is also a condition of the BIGs facility detailed in the Schedule of Other Facilities that the liability outstanding at any time be secured by a deposit agreement incorporating a
charge dated 6th November 2000 from the Company over cash deposits in an aggregate amount equal to such liability outstanding at the relevant time.

Financial Information

Whilst the facility and/or any of the other facilities remain available you should provide to the Bank as soon as possible after the end of the period to which
they relate copies of any financial information that the Bank may from time to time reasonably request, including:

You
should also provide to the Bank, at least 10 days prior to the commencement of each quarter, a copy of your cashflow and budget for the quarter then commencing.

Other Facilities

In addition to the overdraft facility we are pleased to offer to you the facilities detailed in the Schedule of Other Facilities. Except when reference is made to
another agreement each additional facility will be available upon such terms and conditions as shall from time to time be specified by the Bank. The facilities may be cancelled by the Bank at any time
but it is the Bank's present intention to keep the facilities in place for the period of availability of the overdraft facility and your liability in respect of any utilisation may extend beyond such
period of availability.

Amounts
outstanding in connection with the foreign exchange facility, the indemnity line, the negotiations facility, the TravelLink facility and the Lloyds Auto Dealing facility may be
in sterling and/or any other currency. For the purpose of determining whether there is sufficient availability within the specified limit for any particular utilisation amounts outstanding in a
currency other than sterling shall be notionally converted into sterling on the date of the proposed utilization on the basis of the rate at which the Bank would sell the relevant currency for
sterling at that time.

If
upon termination of the overdraft facility (or earlier cancellation of any of these additional facilities) there are any foreign exchange contracts outstanding or any contingent
liabilities existing under these additional facilities (or any of them) the Bank shall have the right at any time to close out any such foreign exchange contracts and upon any request from the Bank:



For
the purposes of the above the Bank shall have the right at the time of making demand or at any time thereafter to convert all amounts then due and payable in connection with any of
these additional facilities in a currency other than sterling into sterling at the Bank's exchange rate for selling that currency against sterling at that time. The Bank shall a soon as possible after
such conversion advise the sterling amount then owing.

The
Bank may debit any amount owing in connection with these additional facilities to your account with the Bank whether or not that would cause the account to become overdrawn or the
agreed overdraft limit on the account to be breached.

Other Terms of Offer

This letter if for the benefit of the contracting parties only and shall not confer any benefit on or be enforceable by a third party.

Please
confirm your acceptance of the facilities offered by returning the attached duplicate of this letter with the acknowledgement signed in accordance with the bank mandate currently
held by the
