Today, Commerce's Directors, by unanimous consent, approved, ratified and confirmed the contents of this letter and authorized me to submit its understanding of your status, which is as follows: 1. Promissory Notes and Other Obligations A series of open-ended, secured, on-demand promissory notes (Notes) are due to the SM RIRA. Their combined amount is $503,580.95 as of March 31, 2004. These Notes bear interest, payable monthly, at the rate of 3% over the prime rate established from time to time by the First National Bank of Chicago, Chicago, Illinois, (now Bank One), but not less than 16% per annum (Schedule of Principal and Interest as of March 31, 2004, Exhibit A).

Reference is made to Historical information - San Sebastian Gold Mine Concession. (2) New SSGM Exploration Concession/License (New SSGM) approximately 40.7694 square kilometers (10,070 acres) On October 20, 2002, the Company applied for the New SSGM, which covers an area of 42 square kilometers and includes approximately 1.2306 square kilometers of the Renewed SSGM. The New SSGM is in the jurisdiction of the City of Santa Rosa de Lima in the Department of La Union and in the Nueva Esparta in the Department of Morazan, Republic of El Salvador, Central America. On February 24, 2003, the El Salvador Department of Hydrocarbons and Mines (DHM) issued the New SSGM for a period of four years starting from the date following the notification of this resolution which was received on March 3, 2003. The New SSGM may be extended for two two-year periods, or for a total of eight years.

Acknowledgment of collateral provided during the current fiscal year March 31, 2004 Commerce's Directors have on May 10, 2004 authorized and directed Commerce's Officers to assign all of the rights, titles, claims, remedies and interest it has to GLSCO, ELM, the ELM RIRA, the SM RIRA and SM, collectively and individually referred to as Lenders, as collateral for all of the outstanding loans and obligations as of March 31, 2004, including all future advances of any kind as follows: (1) Renewed San Sebastian Gold Mine Exploitation Concession/License (Renewed SSGM) - approximately 1.2306 square kilometers (304 acres), Department of La Union, El Salvador, Central America (pledged and assigned as collateral on May 10, 2004) On September 6, 2002, at a meeting held with the El Salvadoran Minister of Economy and the DHM, it was agreed to submit an application for the Renewed SSGM for a 30-year term and to simultaneously cancel the concession obtained on July 23, 1987. On September 26, 2002, the Company filed this application. On February 28, 2003 (received March 3, 2003) the DHM admitted to the receipt of the application and the Company proceeded to file public notices as required by Article 40 of the El Salvadoran Mining Law and its Reform (MLIR). On April 16, 2003, the Company's El Salvadoran legal counsel filed with the DHM notice that it believed that it complied with the requirements of Article 40, and that there were no objections; and requested that the DHM make its inspection as required by MLIR Article 42. The Company then provided a bond which was required by the DHM to protect third parties against any damage caused from the mining operations, and it simultaneously paid the annual surface tax. On August 29, 2003 the Office of the Ministry of Economy Mrs. Sylvia Machulak Sylvia Machulak Rollover Individual Retirement Account May 10, 2004 Page 5 of 8 Pages formally presented the Company with the twenty-year Renewed SSGM which was dated August 18, 2003. This Renewed SSGM replaces the collateral that the same parties held with the previous concession. A copy of the assignment dated May 10, 2004, is attached to this document (Exhibit B) and the Renewed SSGM agreement is attached to it and referred to as Exhibit 1. (2) San Cristobal Mill and Plant (SCMP) three-year lease by and between Commerce and Corporacion Salvadorena de Inversiones (Corsain), an El Salvadoran governmental agency, executed on Monday, April 26, 2004, retroactive to November 13, 2003. Pledged and assigned as collateral on May 10, 2004. The renewed three-year SCMP lease for the property located near the City of El Divisadero was finalized and executed on Monday, April 26, 2004, and is retroactive to November 13, 2003. This May 10, 2004 assignment is included in Exhibit B and the lease agreement is attached to it and referred to as Exhibit 2. 5. Cross Pledge Collateral Agreement GLSCO, ELM, the ELM RIRA, the SM RIRA and SM individually are entitled to specific collateral that has been pledged to them by Commerce, its subsidiaries, affiliates and the Joint Venture. Upon default by Commerce, or its subsidiaries or affiliates or the Joint Venture, then GLSCO, ELM, the ELM RIRA, the SM RIRA and SM have the first right to the proceeds from the specific collateral pledged to each of them. Commerce, its subsidiaries, affiliates and the Joint Venture, also have cross-pledged the collateral without diminishing the rights of the specific collateral pledged to each of the following: GLSCO, ELM, the ELM RIRA, the SM RIRA and SM. The purpose and the intent of the cross pledge of collateral is to assure GLSCO, ELM, the ELM RIRA, the SM RIRA and SM, that each of them would be paid in full; thus, any excess collateral that would be available is for the purpose of satisfying any debts and obligations due to each of the named parties. The formula to be used (after deducting the payments made from the specific collateral) is to total all of the debts due to GLSCO, ELM, the ELM RIRA, the SM RIRA and SM, and then to divide this total debt into each individual debt to establish each individual's percentage of the outstanding debt due. This percentage then will be multiplied by the total of the excess collateral to determine the amount of proceeds derived from the excess collateral and then the amount due to each of them would be distributed accordingly. Mrs. Sylvia Machulak Sylvia Machulak Rollover Individual Retirement Account May 10, 2004 Page 6 of 8 Pages 6. Cancellation of Inter-Company Debts Upon Default Since certain of the collateral specifically or collectively pledged to GLSCO, ELM, the ELM RIRA, the SM RIRA and SM consists of the common stock of Homespan, Ecomm, Sanseb, SLE, Misanse, UDI and the interest in the ownership of the Joint Venture, Commerce agreed, upon default of the payment of principal or interest to any of the individual Lender(s) mentioned herein, that it will automatically cancel any inter-company debts owed to Commerce by any of its wholly-owned subsidiaries or affiliates or the Joint Venture at such time as any of the stock or Joint Venture ownership is transferred to the collateral holders as a result of default of any promissory note. 7. Guarantors This agreement further confirms that Commerce and all of the following are guarantors to the obligations due to SM and to the loans made by the SM RIRA to Commerce: Joint Venture, Homespan, Ecomm, SLE, Sanseb and UDI. They jointly and severally guarantee payment of the note(s) that they caused to be issued and also agree that these note(s) may be accelerated in accordance with the provisions contained in the agreement and/or any collateral or mortgages securing these notes. Also, Commerce, all of its subsidiaries and the Joint Venture agree to the cross pledge of collateral for the benefit of GLSCO, ELM, the ELM RIRA, the SM RIRA, and SM. Reference is made to Exhibit 5 included in the April 9, 1990 confirmation letter. 8. Re-Execution Agreement(s) In the event the SM RIRA and/or SM deems that it is necessary or advisable for the SM RIRA and/or SM to have Commerce re-execute any document(s) entered into, including, but not limited to the promissory note(s) or collateral agreement(s), Commerce will re-execute such document(s) reasonably required by the SM RIRA and/or SM. Commerce also acknowledges that Commerce may be liable to pay certain costs related to any of the transactions entered into with the SM RIRA and/or SM. If at a later date the SM RIRA and/or SM determines that an error has been made in the payment of such costs to the SM RIRA and/or SM, then the SM RIRA and/or SM may demand payment and Commerce does hereby agree to make such payment forthwith. All requests for corrections of any errors and/or payment of costs shall be complied with by Commerce within seven (7) days of the SM RIRA's and/or SM's written request. The failure of Commerce to comply with Commerce's obligation(s) hereunder shall constitute a default and shall entitle the SM RIRA and/or SM to the Mrs. Sylvia Machulak Sylvia Machulak Rollover Individual Retirement Account May 10, 2004 Page 7 of 8 Pages remedies available for default under any provisions of the agreements including, but not limited to the promissory note(s) and/or the collateral pledge agreement(s) and/or any other Commerce obligation(s). 9. Omissions Commerce believes that it has included all of its obligations, monies due and has listed all of the collateral due to the SM RIRA and/or SM, however, since these transactions have taken place over a long period of time in which changes could have taken place, it is possible that inadvertently some item(s), particularly collateral, could have been omitted. If that should prove to be a fact, then Commerce, the Joint Venture, Homespan, Ecomm, SLE, Sanseb, and UDI agree that those omissions of collateral, if any, are meant to be included as collateral under this confirmation agreement. If you are in agreement with the contents of this letter, please sign below and return one copy to Commerce. Very truly yours, COMMERCE GROUP CORP. /s/ Edward A. Machulak Edward A.
