ITEM 5. OTHER EVENTS.

        Environmental Remediation Holding Corp., a Colorado corporation
("ERHC"), and The Democratic Republic of Sao Tome Principe ("DRSTP") have
agreed that, should a treaty between The Federal Republic of Nigeria and DRSTP
on the joint development of petroleum and other resources in areas of the
exclusive economic zone of the two nations become effective (the "Treaty"), a
Memorandum Agreement (the "Memorandum Agreement") dated May 21, 2001 between
ERHC and DRSTP will then become effective and be in effect through September
30, 2024.  Should the Treaty not become effective by May 21, 2003, (i) the
Memorandum Agreement will be null and void and (ii) the arbitration
proceedings in accordance with the Rules of Arbitration of the United Nations
Commission on International Trade Law regarding the agreements described in
the following paragraph ("the Current Arbitration") will resume.

        DRSTP and ERHC, together, at certain times, with Procura Financial
Consultants, C.C. ("Procura"), entered into various memoranda of agreement,
letters and stipulations regarding the evaluation and study of oil, gas and
mineral reserves within DRSTP.  Those documents include: (i) a Letter of
Understanding between DRSTP and ERHC dated May 18, 1997; (ii) a Memorandum of
Agreement between DRSTP on the one hand and ERHC/Procura on the other hand
dated May 27, 1997; (iii) a Memorandum of Understanding between DRSTP and ERHC
dated December 30, 1997; and (iv) a Stipulation by and between DRSTP and ERHC
dated November 20, 1997 (documents (i) through (iv) are collectively referred
to as the "Original Agreement").  Pursuant to the Memorandum of Agreement,
ERHC and DRSTP have agreed to cease the Current Arbitration and amend various
terms of the Original Agreement.

        The Memorandum Agreement is set forth in Exhibit 1 to this Form 8-K
and is incorporated herein in its entirety by reference in response to this
Item.  The foregoing description of the terms and provisions of the Memorandum
Agreement is a summary only, and is qualified in its entirety by reference to
such document.

        Pursuant to the Memorandum Agreement, ERHC will (i) relinquish its
rights to negotiate on behalf of DRSTP with oil companies the remaining
concessions to be leased and developed and the right to receive a 5% override
payable by those oil companies for ERHC's services, (ii) assign its 49%
ownership in Sao Tome and Principe National Petroleum Company S.A. ("STPetro")
to DRSTP and (iii) relinquish its right, through its ownership in STPetro, to
a minimum of the four best concessions in the Exclusive Economic Zone (as
defined in the Memorandum Agreement) of DRSTP.

        Pursuant to the Memorandum Agreement DRSTP will (i) assign to ERHC 10%
of its share of all Profit Oil (as defined in the Memorandum Agreement)
received from operations conducted in the Joint Development Zone (as defined
in the Memorandum Agreement), (ii) assign to ERHC 5% of its share of all
Signature Bonuses (as defined in the Memorandum Agreement) paid by contractors
operating within the Joint Development Zone, (iii) grant ERHC the right to
receive a 1.5% overriding royalty interest in all the production of crude oil
and/or natural gas in the Joint Development Zone, (iv) grant ERHC the option
to acquire up to a 15% paid working interest in up to two blocks of ERHC's
choice in the Joint Development Zone (this working interest option must be
exercised by ERHC prior to the signature of an Exploration and Production
Agreement (as defined in the Memorandum Agreement) with an operator), (v) award


                                        2


to ERHC up to two blocks of ERHC's choice in the Exclusive Economic Zone but
outside the Joint Development Zone for development (DRSTP will have the prior
right to reserve up to a maximum of the first three blocks) and (vi) grant
ERHC the option to acquire up to a 15% paid working interest in up to two
blocks of ERHC's choice in the Exclusive Economic Zone but outside the Joint
Development Zone (this working interest option must be exercised by ERHC prior
to the signature of an Exploration and Production Agreement with an operator).

        In addition, ERHC will pay income tax on net income received from
DRSTP obligations under the Memorandum Agreement and ERHC's interest in the
Memorandum Agreement is assignable to a subsidiary of ERHC without DRSTP's
consent.  However, written consent must be obtained if an assignee is not a
subsidiary of ERHC.
