Offer by Hoare Govett Limited on behalf of Rosneft Investments Limited

Anglo Siberian Oil Company plc has today mailed the following letter to its
shareholders:
--------------------------------------------------------------------------------

Dear Shareholder,

Offer from Rosneft Investments Limited ("Rosneft")

We refer to the cash offer of #1 per share made by Hoare Govett on behalf of
Rosneft to all shareholders on 4 April 2003.  We understand from Hoare Govett
that the formal offer has been sent to all shareholders.

The Board of Anglo Siberian Oil Company plc (the "Company") is evaluating the
terms of the offer and will be writing shortly to shareholders.  In the
meantime, the Board advises shareholders to take no action.

Extraordinary General Meeting ("EGM") to be held on 11 April 2003

As shareholders are aware, an EGM has been requisitioned by Lynminster Limited,
a shareholder in the Company, which is to be held next Friday, 11 April 2003, at
the offices of the Company's public relations adviser, Hudson Sandler, at 29
Cloth Fair, London  EC1A 7NN.  Lynminster seeks to remove all the existing
directors, both executive and non-executive, and replace them with its own
nominees.

The Board believes that it would be in the interests of shareholders for the
present directors to remain in office as they are in the best position to form
an independent assessment of the offer received from Rosneft.  Accordingly, they
ask for your support.  To be valid, forms of proxy need to be received by the
registrars not later than 11.00 a.m. on Wednesday 9 April 2003.

Yours sincerely

David G M Boyd
Chairman
