(1) Includes 7,190,000 shares of Zydeco Common Stock, par value $.001 per share
(the "Common Stock") issuable upon conversion by Mr. Simpson of 7,190 shares of
Zydeco Energy, Inc. ("Zydeco") Series A Convertible Preferred Stock, par value
$.001 per share (the "Series A Preferred Stock"). Each share of Series A
Preferred Stock is convertible into 1,000 shares of Zydeco Common Stock. The
Series A Preferred Stock will be automatically converted into Common Stock when
an amendment to Zydeco's Certificate of Incorporation to increase the number of
shares of Common Stock that Zydeco is authorized to issue is approved by the
Zydeco stockholders so that there is a sufficient number of authorized but
unissued and unreserved shares of Common Stock available for Zydeco to issue
upon conversion of the Series A Preferred Stock owned by Mr. Simpson.
Currently, Mr. Simpson, in his positions as sole director and majority
stockholder of Zydeco, would have the power to cause such an amendment to be
adopted and approved at a special meeting of the Zydeco stockholders.
(2) Calculated based upon the total of: (i) 42,775,951 shares of Common Stock
outstanding as of June 9, 2000, and (ii) an additional 7,190,000 shares of
Common Stock issuable upon conversion of the Series A Preferred Stock issued to
Mr. Simpson.

ITEM 1. SECURITY AND ISSUER
This Schedule 13D relates to the shares of common stock, par value
$.001 per share (the "Common Stock"), of Zydeco Energy, Inc., a Delaware
corporation ("Zydeco"). On May 23, 2000, Zydeco and its wholly-owned subsidiary
DVN Acquisition Corporation ("DVN Acquisition") entered into an Agreement and
Plan of Merger (the "Merger Agreement") with DataVoN Inc., a Texas corporation
("DataVoN"), pursuant to which DVN Acquisition merged with and into DataVoN on
June 9, 2000, with DataVoN continuing as the surviving corporation and wholly-
owned subsidiary of Zydeco.
As a result of the merger, Mr. Simpson received 31,548,877 shares of
Common Stock and 7,190 shares of Zydeco Series A Convertible Preferred Stock,
par value $.001 per share (the "Series A Preferred Stock") in exchange for his
shares of common stock of DataVoN. Each share of Series A Preferred Stock is
convertible into 1,000 shares of Common Stock.
Mr. Simpson was issued shares of Series A Convertible Preferred Stock
in the merger because of an insufficient number of authorized but unissued or
unreserved shares of Common Stock. It is expected that Zydeco's Certificate of
Incorporation will be proposed to the Zydeco stockholders for amendment to
increase the number of shares of Common Stock that Zydeco is authorized to
issue. If Zydeco's Certificate of Incorporation is so amended, all outstanding
shares of Series A Preferred Stock will be automatically converted into Common
Stock pursuant to their terms.
The principal executive offices of Zydeco are located at 635 West
Campbell Road, Suite 130, Richardson, Texas 75080.

a criminal proceeding (excluding traffic violations or similar
misdemeanors).
(e) During the last five years, Mr. Simpson was not a party to a civil
proceeding of a judicial or administrative body of competent
jurisdiction and as a result of such proceeding was or is subject
to a judgment, decree or final order enjoining future violations
of, or prohibiting or mandating activities subject to, Federal or
State securities laws or finding any violation with respect to
such laws.
(f) Citizenship:
Mr. Simpson is a United States citizen.
ITEM 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION
Pursuant to the terms of the Merger Agreement, Mr. Simpson exchanged
973,000 shares of DataVoN common stock beneficially owned by him for 31,548,877
shares of Common Stock and 7,190 shares of Series A Preferred Stock. Mr.
Simpson did not tender any other consideration for the shares of Common Stock or
the shares of Series A Preferred Stock he received as a result of the merger.
No separate funds or other consideration were received by Mr. Simpson in
connection with the shares of Common Stock or the shares of Series A Preferred
Stock he received in the merger.
ITEM 4. PURPOSE OF TRANSACTION
Mr. Simpson has acquired the securities specified in Item 5 of this
Schedule 13D as a result of the transactions contemplated in the Merger
Agreement. Mr. Simpson was the largest shareholder of DataVoN, beneficially
owning approximately 97.3% of the shares of common stock of DataVoN. As a
result of the merger, Mr. Simpson is the largest stockholder of Zydeco,
beneficially owning approximately 77.5% of the shares of Common Stock
outstanding as of June 9, 2000, assuming the conversion by Mr. Simpson of the
7,190 shares of Series A Preferred Stock beneficially owned by him.
Mr. Simpson may from time to time acquire additional securities of
Zydeco or at any time dispose of securities of Zydeco he now beneficially owns
or hereafter may acquire.

It is expected that an amendment to the Certificate of Incorporation of
Zydeco will be proposed to the Zydeco stockholders to (i) increase the number of
shares of Common Stock that Zydeco is authorized to issue, and (ii) change the
name of the corporation to DataVoN Inc. If the Certificate of Incorporation is
so amended, all outstanding shares of the Series A Preferred stock issued in the
merger will be automatically converted into Common Stock by their terms.
ITEM 5. INTEREST IN SECURITIES OF THE ISSUER
Mr. Simpson beneficially owns, and has the sole power to vote and
dispose of, 38,738,877 shares, or 77.5%, of the outstanding shares of Common
Stock. The calculation of ownership set forth herein is based upon 42,775,951
shares of Common Stock outstanding as of June 9, 2000, as indicated on the
records of the transfer agent, and assumes the conversion by Mr. Simpson of the
7,190 shares of Series A Preferred Stock beneficially owned by him into
7,190,000 shares of Common Stock. The Series A Preferred Stock will be
automatically converted into Common Stock when an amendment to Zydeco's
Certificate of Incorporation to increase the number of shares of Common Stock
that Zydeco is authorized to issue is approved by the Zydeco stockholders so
that there is a sufficient number of authorized but unissued and unreserved
shares of Common Stock available for Zydeco to issue upon conversion of the
Series A Preferred Stock.
ITEM 6. CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT
TO SECURITIES OF THE ISSUER

relationships (legal or otherwise) between Mr. Simpson and any person with
respect to the securities of Zydeco.
