ITEM 5: OTHER EVENTS

      On March 17, 2002 Esenjay Exploration, Inc., a Delaware corporation
("Esenjay"), Santos Americas and Europe Corporation, a Delaware corporation
("Parent"), and ECM Acquisition Company, a Delaware corporation and a
wholly-owned subsidiary of Parent ("Sub"), entered into an Agreement dated March
17, 2002 (the "Merger Agreement") pursuant to which Sub has agreed to commence a
tender offer (the "Offer") for all outstanding shares of Esenjay common stock,
par value $0.01 (the "Common Stock") at a price per share of $2.84 in cash (the
"Offer Price"). The Merger Agreement provides for a two-step transaction. The
first step would be the Offer and the second step would be a follow-on merger
between Sub and Esenjay in which Esenjay would be the surviving corporation.
Esenjay issued a press release announcing the execution of the Merger Agreement
on March 18, 2002, a copy of which is filed as Exhibit 99.1 hereto and which is
incorporated herein by reference.

      The Offer is conditioned on the receipt of at least a majority of
Esenjay's outstanding shares. If Sub consummates the Offer, it will then begin
the follow-on merger to acquire all remaining outstanding Esenjay shares, the
timing of which would be announced at a later date. As of March 1, 2002 Esenjay
had 19,121,568 shares outstanding. It also had outstanding options and warrants,
which would be in-the-money at $2.84 per share, to purchase an additional
2,537,169 Esenjay common shares.

      At a meeting held on Saturday, March 16, 2002, Esenjay's board of
directors voted to accept and support the Offer and voted to recommend that
Esenjay shareholders accept the cash tender offer and approve the merger. In
addition, as a condition to the Offer, Esenjay's two major shareholders and the
Chairman of the Board of Directors have agreed to tender all of the shares owned
by them (representing approximately 52% of Esenjay's total outstanding shares)
in the Offer and have granted Parent the option to acquire all of their shares
if the Offer is not consummated for certain reasons.

      Consummation of the Offer is further subject to various other conditions
as set forth in the Merger Agreement. The foregoing summary of certain facets of
the Offer and the Merger Agreement is qualified in its entirety by reference to
the text of the Merger Agreement, a copy of which is filed as Exhibit 2.1 hereto
and which is incorporated herein by reference.
