EXPLANATORY NOTE

SulphCo, Inc. (the Company) is filing this Amendment No. 4 to Form 10-QSB/A (Amendment
No. 4) to amend its Quarterly Report on Form 10-QSB for the period ended June 30, 2004 (the
Original Filing) filed on August 16, 2004 with the Securities and Exchange Commission
(SEC), as amended by Amendment No. 1 filed with the SEC on November 23, 2004, Amendment
No. 2 filed with the SEC on January 24, 2005, and Amendment No. 3 filed with the SEC on February
9, 2005 (Amendment Nos. 1-3 inclusive being referred to as the Prior Amendments) in order
to (i) refile in its entirety Part I - Item 1. Financial Statements to amend its unaudited
financial statements for the periods ended June 30, 2004, and June 30, 2003, and (ii) to include
new Exhibits 31.1, 31.2 and 32.1.

The
Company has identified certain errors in its previously issued financial statements related to the
capitalization of certain research and development expenses in the amount of $101,606 for the year
ended December 31, 2003 and $6,364 for the quarter ended March 31, 2004. As a result, the Company has restated its previously issued financial statements
for the year ended December 31, 2003, to reflect this amount as a 2003 expense. These restated financial
statements are now included in Amendment No. 7 to Form 10-KSB for the year ended December 31, 2003.
This Amendment No. 4 is being filed primarily to reflect adjustments related to the 2003 restatement.

The Company is also amending the financial statements included in this report to reflect corrections to the Statement of Cashflows. There were no other material changes from the financial statements filed with the Original Filing as amended by the Prior Amendments.

This Amendment does not amend any other information previously filed in the Original Filing as amended
by the Prior Amendments. The Original Filing as amended by the Prior Amendments is hereby superseded
and amended with respect to the information set forth in this Amendment No. 4.

|   | Financial instruments, which potentially subject the Company to concentrations of credit risk, consist
mainly of cash equivalents. The Company maintains amounts on deposit with financial institutions,
which exceed federally insured limits. The Company has not experienced any significant losses in
such accounts, nor does management believe it is exposed to any significant credit risk.
|   |                                                                                                                                                                                                                                                                                                                                                                                                   
|   | There are various claims and lawsuits pending against the Company arising in the normal course of the
Companys business. Although the amount of liability at June 30, 2004, cannot be ascertained,
management is of the opinion that any resulting liability will not materially affect the Companys
financial position.
