Mrs. Sylvia Machulak as an
Individual and for her Rollover
Individual Retirement Account
903 West Green Tree Road
River Hills, Wisconsin  53217

Dear Mrs. Machulak:

At today's Commerce Group Corp. (Commerce) Directors' meeting, the
Directors were informed about the annual confirmation, disclosure and
status letter that you requested from Commerce and its affiliates to
establish and confirm the amount due and the collateral pledged along
with any other Commerce obligations or agreements made to the Sylvia
Machulak Rollover Retirement Account (SM RIRA) and to Sylvia Machulak as
an individual/consultant (SM), both referred to as Lenders, as of
Commerce's fiscal year ended March 31, 2005.  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 with Commerce, which is as follows:

1.  Promissory Notes

    The total amount of all of the open-ended, secured, on-demand
    promissory notes (Notes) together with interest due to the SM RIRA is
    $591,628.78 as of March 31, 2005.  These Note(s) 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, (then Bank One; now the prime rate published in the Wall
    Street Journal), but not less than 16% per annum (Schedule of
    Principal and Interest as of March 31, 2005, Exhibit A).  Commerce is
    no longer issuing monthly Notes for the payment of interest, etc.,
    but pursuant to our understanding, Commerce is augmenting all
    additions and advances made by the SM RIRA, and it will deduct any
    payments or credits made by Commerce to the current open-ended,
    secured, on-demand, outstanding Notes issued or obligations owed to
    the SM RIRA.

    However, on this date, Commerce's Directors have authorized its
    Officers to issue renewed annual note(s) (Exhibit B) so that the
    Lender will have a current substituted dated debt instrument.  The
    Directors acknowledged that the issuance of note(s) for each
    transaction are too cumbersome and are not practicable to manage.
    Also, the length of time involved and the number of transactions make
    it impractical to devote the time and effort to issue a note for each
    transaction.  Therefore, the Directors have unanimously agreed to the
    following resolution, which was adopted on May 9, 2005:

         WHEREAS, in the past 20 years or more the following parties:
    General Lumber & Supply Co., Inc. (GLSCO); Edward L. Machulak  as an
    individual and not as a Director or Officer of Commerce (ELM); the
    Edward L. Machulak Rollover Individual Retirement Account (ELM RIRA),
    the Sylvia Machulak Rollover Individual Retirement Account (SM RIRA),
    and Sylvia Machulak, as a consultant and as an individual (SM),
    hereafter collectively and individually identified as the Lender(s),
    have accounted for advancing cash funds, earning accrued interest,
    and for appropriate credit which was reconciled to the open-ended,
    secured, on-demand notes(s); and

         WHEREAS, the Directors desire to minimize the record keeping in
    these transactions without jeopardizing, diminishing, altering,
    changing or losing any rights that the Lenders have by changing the
    procedures in handling the recording of any notes(s) issued or to be
    issued; and

         WHEREAS, in order to provide an easier accounting facility by
    renewing the notes(s) on an annual basis to coincide with the
    Company's fiscal year (which presently ends on March 31) and to
    incorporate said renewed note(s) with the annual confirmation
    agreement(s); and

         WHEREAS, prior to the change to issue substituted renewed
    note(s), the initial promissory note(s) were considered to be
    open-ended, secured, on-demand and the additions and deductions were
    recognized by separate accounting records; therefore, be it

              RESOLVED, That the Directors authorize and empower the
          Officers to substitute and issue renewed consolidated
          promissory note(s) at the end of each fiscal year beginning
          with the Company's fiscal year ended March 31, 2005 to the
          following: General Lumber & Supply Co., Inc. (GLSCO); Edward L.
          Machulak  as an individual and not as a Director or Officer of
          Commerce (ELM); the Edward L.  Machulak Rollover Individual
          Retirement Account (ELM RIRA), the Sylvia Machulak Rollover
          Individual Retirement Account

          (SM RIRA), and Sylvia Machulak, as a consultant and as an
          individual (SM), hereafter collectively and individually
          identified as the Lender(s); and

               BE IT FURTHER RESOLVED, That the Officers of the Company
          are authorized and empowered to assure the Lender(s) that by
          substituting and consolidating the existing note(s) and issuing
          the renewed note(s) on the last day of the Company's fiscal
          year beginning with March 31, 2005 with the understanding that
          the intention is that the Lender(s) will not jeopardize, lose,
          diminish, risk, alter or change any rights, including the
          pledge of collateral, that are inherent with the initial
          note(s) by the issuance of annual renewed open-ended, secured,
          on-demand promissory note(s); and

               BE IT FURTHER RESOLVED, That the Directors acknowledge
          that the only purpose of the change and substitution to issue
          annual renewed notes(s) is for the convenience, reduced
          accounting and reducing the paperwork involved; and

               BE IT FURTHER RESOVED, That the Officers are authorized
          and empowered to perform any act that they deem necessary to
          accommodate the purpose of issuing annual renewed note(s).

2.  Other Obligations - Consulting Fees Due to Sylvia Machulak as an
    Individual (SM)

    further acknowledge the continuance of SM's services at a sum of
    $3,000 per month beginning on October 1, 2000, and continuing until
    such time as terminated by the Directors or the President.
    Therefore, the amount due to SM as of March 31, 2005, is $363,600 (72
    months at $2,800 and 54 months at $3,000).  Reference is made to
    Exhibit B included in the April 5, 1996 confirmation letter.

        (2)  New SSGM Exploration Concession/License (New SSGM) -
             approximately 40.7694 square kilometers (10,070 acres)
             Government of El Salvador Resolution No. 27.

             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.
             Besides the San Sebastian Gold Mine,  three other formerly
             operative gold and silver mines known as the La Lola Mine,
             the Santa Lucia Mine, and the Tabanco Mine are included in
             the New SSGM and are being explored.  The Company has
             complied as required by filing its annual activity report
             and it paid the annual surface tax.  This concession had
             been assigned collectively to all of the Lenders named
             herein on May 12, 2003 and the assignment was included in
             the May 12, 2003 confirmation agreement as Exhibit B.

        (3)  Lease agreement by and between Mineral San Sebastian
             Sociedad Anomina de Capital Variable (Misanse) and Commerce
             dated January 14, 2003

             The term of this lease agreement coincides with the term of
             the Renewed San Sebastian Gold Mine Exploitation Concession
             and consists of 1,470 acres owned by Misanse.  This lease
             agreement has been assigned to all of the Lenders named
             herein on May 12, 2003 and the assignment was included in
             the May 12, 2003 confirmation agreement as Exhibit B.

        (4)  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) Government of El Salvador
             Agreement No. 591.

             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 t ax.  On August 29,
             2003 the Office of the Ministry of Economy 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.  On May 20, 2004 (delivered June 4, 2004) the
             Government of El Salvador, under their Agreement Number 591,
             extended the exploitation concession for a period of 30
             years.  A copy of the assignment dated May 10, 2004, is
             attached to the May 10, 2004 confirmation letter as Exhibit
             B and the Renewed SSGM agreement is attached to Exhibit B
             and referred to as Exhibit 1.

        (5)  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 the May
             10, 2004 confirmation letter as Exhibit B and the lease
             agreement is attached to Exhibit B and referred to as
             Exhibit 2.

    c.  Acknowledgment of collateral provided through May 9, 2005

        Commerce's Directors have on May 9, 2005 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
        additional collateral for all of the outstanding loans and
        obligations as of March 31, 2005, including all future advances
        of any kind.  Collateral that has been provided through May 9,
        2005 is:

        Nueva Esparta Exploration Concession/License (Nueva Esparta) - 45
        square kilometers (11,115 acres) Resolution No. 271

        On or about October 20, 2002, the Company filed an application
        with the DHM for the Nueva Esparta Exploration Concession/License
        which consists of 45 square kilometers and is located north and
        adjacent to the New SSGM.  On May 25, 2004 the Government of El
        Salvador, under their Resolution No. 271, issued the Nueva
        Esparta Exploration Concession/License for a period of four years
        starting from the date following the notification of this
        resolution which was received on June 4, 2004.  This
        concession/license may be extended for two two-year periods or
        for a total of eight years.  This rectangular area is in the
        Departments of La Union (east) and Morazan (west) and in the
        jurisdiction of the City of Santa Rosa de Lima, El Salvador,
        Central America.  Included in the Nueva Esparta are eight other
        formerly operated gold and silver mines known as:  the Banadero
        Mine, the Carrizal Mine, the Copetillo Mine, the Grande Mine, the
        La Joya Mine, the Las Pinas Mine, the Montemayor Mine, and the Or
        o Mine.  A copy of the assignment dated May 9, 2005 is attached
        to this document (Exhibit C) and the Nueva Esparta Exploration
        Concession is attached to Exhibit C and referred to as Exhibit 1.

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

<PAGE>
Mrs. Sylvia Machulak
Sylvia Machulak
Rollover Individual Retirement Account
May 9, 2005
Page 8 of 10 Pages


    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 each party should
    receive from the excess collateral.  Then the amount due to each of
    them would be distributed accordingly.

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

<PAGE>
Mrs. Sylvia Machulak
Sylvia Machulak
Rollover Individual Retirement Account
May 9, 2005
Page 9 of 10 Pages

    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 defaul t and shall entitle
    the SM RIRA and/or SM to the 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.

                         RENEWED PROMISSORY NOTE


Borrower: Commerce Group Corp.            Lender:  Sylvia Machulak RIRA
          6001 North 91st Street                   903 West Green Tree Rd.
          Milwaukee, WI  53225                     Milwaukee, WI  53217

Principal Amount:      $591,628.78
Initial Rate:          3.000% + prime rate, but not less than 16.000%
Date of Renewed Note:  March 31, 2005

PROMISE TO PAY.  COMMERCE GROUP CORP. ("Borrower") promises to pay to the
SYLVIA  MACHULAK ROLLOVER INDIVIDUAL RETIREMENT ACCOUNT ("Lender"), or
order, in lawful money of the United States of America, the principal
amount of Five Hundred Ninety One Thousand Six Hundred Twenty Eight and
78/100 Dollars ($591,628.78), together with interest, paid monthly, on
the unpaid principal balance from March 31, 2005, until paid in full.

PAYMENT.  This is an open-ended, secured, on-demand payment, renewed
promissory note.  Interest is to be paid monthly.  The Lender, at its
discretion, can add the monthly interest due to the principal balance.
Unless otherwise agreed or required by applicable law, payments will be
applied first to any accrued unpaid interest; and then to principal.  The
annual interest rate for this Note is computed on a 365/360 basis; that
is, by applying the ratio of the annual interest rate over a year of 360
days, multiplied by the outstanding principal balance, multiplied by the
actual number of days the principal balance is outstanding and the
interest is payable monthly.  Borrower will pay Lender at Lender's
address shown above or at such other place as Lender may designate in
writing.

VARIABLE INTEREST RATE.  The interest rate on this Note is subject to
change from time to time based on changes in the prime rate as quoted in
the Wall Street Journal plus three percent, but not less than sixteen
percent per annum.  Borrower understands that Lender may make loans to
the Borrower based on other rates as well.  The prime rate currently is
5.750% per annum.  The interest rate to be applied to the unpaid
principal balance of this Note will be at a rate of 3.000 percentage
points over the prime rate, but not less than 16.000% per annum.  NOTICE:
Under no circumstances will the interest rate on this Note be less than
16.000% per annum or more than the maximum rate allowed by applicable
law.

PREPAYMENT.  Borrower may pay without penalty all or a portion of the
amount owed earlier than it is due.  Early payments will not, unless
agreed to by Lender in writing, relieve Borrower of Borrower's obligation
to pay on demand, the entire amount due.  Rather, any payment will reduce
the principal balance due.  Borrower agrees not to send Lender payments
marked "paid in full," "without recourse," or similar language.  If
Borrower sends such a payment, Lender may accept it without losing any of
Lender's rights under this Note, and Borrower will remain obligated to
pay any further amount owed to Lender.

INTEREST AFTER DEFAULT.  Upon default, including failure to pay on
demand, Lender, at its option, may, if permitted under applicable law,
increase the variable interest rate on this Note to 6.000 percentage
points over the prime rate or over the 16.000% rate, whichever is higher.
The interest rate will not exceed the maximum rate permitted by
applicable law.

DEFAULT.  Each of the following shall constitute an event of default
("Event of Default") under this Note:

     Payment Default.  Borrower fails to make any payment when demand is
     made under this Note.

     Other Defaults.  Borrower fails to comply with or to perform any
     other term, obligation, covenant or condition contained in this Note
     or in any of the related documents or to comply with or to perform
     any term, obligation, covenant or condition contained in any other
     agreement between Lender and Borrower.

<PAGE>

     Default in Favor of Third Parties.  Borrower or any Grantor defaults
     under any loan, extension of credit, security agreement, purchase or
     sales agreement, or any other agreement, in favor of any other
     creditor or person that may materially affect any of Borrower's
     property or Borrower's ability to repay this Note or perform
     Borrower's obligations under this Note or any of the related
     documents.

     False Statements.  Any warranty, representation or statement made or
     furnished to Lender by Borrower or on Borrower's behalf under this
     Note or the related documents is false or misleading in any material
     respect, either now or at the time made or furnished or becomes
     false or misleading at any time thereafter.

     Insolvency.  The dissolution or termination of Borrower's existence
     as a going business, the insolvency of Borrower, the appointment of
     a receiver for any part of Borrower's property, any assignment for
     the benefit of creditors, any type of creditor workout, or the
     commencement of any proceeding under any bankruptcy or insolvency
     laws by or against Borrower.

     Creditor or Forfeiture Proceedings.  Commencement of foreclosure or
     forfeiture proceedings, whether by judicial proceeding, self-help,
     repossession or any other method, by any creditor of Borrower or by
     any governmental agency against any collateral securing the loan.
     However, this Event of Default shall not apply if there is a good
     faith dispute by Borrower as to the validity or reasonableness of
     the claim which is the basis of the creditor or forfeiture
     proceeding and if Borrower gives Lender written notice of the
     creditor or forfeiture proceeding and deposits with Lender monies or
     a surety bond for the creditor or forfeiture proceeding, in an
     amount determined by Lender, in its sole discretion, as being an
     adequate reserve or bond for the dispute.

     Events Affecting Guarantor.  Any of the preceding events occurs with
     respect to any Guarantor of any of the indebtedness or any Guarantor
     disputes the validity of, or liability under, any guaranty of the
     indebtedness evidenced by this Note.

     Adverse Change.  A material adverse change occurs in Borrower's
     financial condition, or Lender believes the prospect of payment or
     performance of this Note is impaired.

     Insecurity.  Lender in good faith believes itself insecure.

LENDER'S RIGHTS.  Upon default or upon demand, the Lender may declare the
entire unpaid principal balance on this Note and all accrued unpaid
interest immediately due, and then Borrower will pay that amount.

COLLATERAL.  Borrower acknowledges this Note is secured by all security
agreements, guarantees, mortgages, and other security instruments
previously granted, contemporaneously granted, and granted in the future,
and it has the collateral and other rights all as contained in a certain
confirmation agreement dated May 10, 2004 between all parties contained
therein, and as subsequently amended and updated from time to time.

ATTORNEYS' FEES; EXPENSES.  Lender may hire or pay someone else to help
collect this Note if Borrower does not pay.  Borrower will pay Lender
that amount.  This includes, subject to any limits under applicable law,
Lender's attorneys' fees and Lender's legal expenses, whether or not
there is a lawsuit, including attorneys' fees, expenses for bankruptcy
proceedings (including efforts to modify or vacate any automatic stay or
injunction), and appeals.  If not prohibited by applicable law, Borrower
also will pay any court costs, in addition to all other sums provided by
law.

GOVERNING LAW.  This Note will be governed by, construed and enforced in
accordance with the laws of the State of Wisconsin.  This Note has been
accepted by Lender in the State of Wisconsin.

<PAGE>

OTHER LOAN AGREEMENTS.  If Borrower and Lender have either previously or
contemporaneously entered into a Loan or Confirmation Agreements, it is
agreed that this Note is subject to the terms and conditions of such Loan
or Confirmation Agreements.  For purpose of this provision, Loan or
Confirmation Agreements shall include, but not be limited to, a Business
Loan Agreement or any other Loan or Confirmation Agreements.

SUCCESSOR INTERESTS.  The terms of this Note shall be binding upon
Borrower, and upon Borrower's successors and assigns, and shall inure to
the benefit of Lender and Lender's heirs, executors, administrators,
successors and assigns.

MINISTRY OF ECONOMY
Republic of El Salvador

                             RESOLUTION No. 271

Ministry of Economy:  San Salvador, at 9:05 AM of the day May 25, 2004.

In view of the Recourse of Appeal introduced into the Directorate of
Hydrocarbons and Mines, on December 19, 2003, before the Minister of
Economy, by Sr. Jose Antonio Alfaro Castro, Lawyer, of this domicile,
acting in his capacity of General Power of Attorney for the Company
"COMMERCE GROUP CORP" of this domicile, against Resolution No. 178 issued
at 14:10 on December 1, of the same year by the cited Directorate, that
declares without standing the request for Exploration License that later
on will say, and,

HAVING READ THE ARGUMENTS AND CONSIDERING:

I.   That through the referenced Resolution the Directorate of
     Hydrocarbons and Mines of this Ministry declared without standing
     the Minerals Exploration License especially for gold an silver that
     Dr. Jose Antonio Alfaro Castro requested in the name of his
     mentioned grantor of Power on October 30, 2002 for the area called
     NUEVA ESPARTA for a surface extension of 45 square kilometers
     identified in cartographic sheet number 2657-III, scale 1 : 50,000
     located in the municipality of Santa Rosa de Lima, in the
     Departments of Morazan and La Union respectively.

II.  That having admitted the Recourse, the files were transferred to the
     Secretary of State with prior notification to the referenced Company
     and receiving it, was sent to be heard for the term of the Law, on
     completing the hearing through the mentioned Power holder, expressed
     that based on Article 45 second line item in the Mining Law, he
     requested an opening of proofs, which was done and as well the
     applicant presented a document in which he stated that the
     Directorate of Hydrocarbons and Mines on issuing the referenced
     Resolution founded it on the following arguments: a) little
     geological investigation of the exploitation program presented
     (SIC); b) lack of sufficient technical capacity to develop the
     project on the part of the professionals proposed by the applying
     Company; c) That the applying Company did not fulfill the
     requirements in the first line item of Article 9 of the Mining Law;
     requirements that refer to the technical and financial capacity to
     develop mining projects.

<PAGE>

III. That in the referred to period of Proof, the applicant presented a
     new work plan prepared by known technicians in the material, in
     which a program of activities is reflected that complies with the
     requirements for this kind of project to be developed in the first
     four years by stages, projecting activities like geological mapping,
     opening of trenches, geochemistry, laboratory analysis; and the
     costs of investment in each stage.  Presenting besides, the
     documents that contain the names of the companies that will
     participate in the Project; as well as the CV's of the companies
     that will participate in it, and the CV's of the technicians in the
     material that have the required qualifications, and the chart of
     investment, costs and expenses of the applying company, copy of the
     correspondence in which is sketched the financial capacity, in which
     for now the invested money has been for the payment of
     administrative expenses and in a lesser scale for investment in
     exploration, referring that it will be increased as reflected in the
     related project; with that it proves compliance with what is
     established in article 9 of the Mining Law.  That with what is
     explained and with the documental proof that is presented, it
     overcomes the deficiencies expressed by the Directorate for
     Hydrocarbons and Mines, who asks that the Declaration Without
     Standing be reconsidered and grant the Exploration License
     requested.

IV.  Upon analyzing the resolution that is impugned, it is warned that in
     it conclusions were expressed in the sense that: " a) little
     geological investigation of the exploitation (sic) program
     presented"; b) "lack of technical capacity sufficient to develop the
     project on the part of the professionals proposed by the requesting
     company", without the argumentation, the criteria or the factual
     reasons being laid out in it that allows any analysis to arrive to
     said conclusions, therefore the reasoning is completely transparent
     in regard to valuing the documents presented with the application.


V.   Consequent with what is expressed, in matters of Exploration
     Licenses it is necessary to understand:  That the text and spirit
     with which the Mining Law was issued, just as it was established in
     the Considering and in its articles 8 and 9, was that of granting
     Exploration Licenses and subsequently a concession for the
     exploration of minerals, to those companies that carry out this
     activity through the application of modern systems that allow fully
     to take advantage of the minerals, having conditioned as a
     requirement to acquire mining rights, the ideal; determining as
     ideal those who proved to have the technical and financial capacity
     to develop mining projects;  that on reviewing the documents
     presented by the appellant as proof are: the new work plan for the
     Nueva Esparta Exploration project; program of exploration for the
     mining project, the program to be developed in four years and in
     four stages, one per year; letter and summary of Financial
     Statements, report of the Public A ccountant of the investment,
     costs and expenses made since January 1, 1999 to June 30, 2003,
     certified Balance Sheets and Financial Statements by

<PAGE>

     the Public Auditor, documentation that has value as proof.  With
     respect to the technical capacity, the names of companies are
     presented with letters of commitment that they will work in the
     exploitation; and curriculum vitae of the technicians that will
     participate in the project. From the latter it is concluded that the
     applying company indeed has a geological exploration project for an
     area with mining background and counts with technical personnel with
     technical capacity to develop the project, for which reason this
     Ministry considers that the applying company complies with the
     requirements that for that purpose the Law establishes in article 9,
     such as having technical and financial capacity to develop the
     mining project and resolves the recourse (of appeal) presented has
     standing.

Therefore,

In use of my legal faculties and based on what is established in Article
45 of the Mining Law and the considerations expressed;

RESOLVE:

1.  The Recourse of Appeal presented December 19, 2003 by Dr. Jose
    Antonio Alfaro Castro in his capacity as Power of Attorney for the
    Company COMMERCE GROUP CORP has standing; and leaves without effect
    Resolution 178 issued by the Directorate of Hydrocarbons and Mines of
    this Ministry at 14:00 hours of the day December 1, 2003.

2.  Returns the present archives to their place of origin to the end of
    granting the License requested.

3.  The Directorate of Mines and Hydrocarbons will proceed to carry out
    the corresponding monitoring to the end of assuring the fulfillment
    of the obligations on the part of the beneficiary under the pain of
    applying the sanctions that are legally applicable.

      deficiencias expresadas por la Direccion de Hidrocarburos y Minas y
      se pide se reconsidera la Declaratoria sin lugar y se otorgue la
      Licencia de exploracion solicidata.

IV.   Al analizar la resolucion que se impugna, se advierte que en la
      misma se expresaron conclusiones en el sentido que:  "a) poca
      investigacion geologica del programa de explotacion presentado; b)
      falta de capacidad tecnica suficiente para desarrollar el proyecto
      de parte de los profesionales propuestos por la sociedad
      solicitante," sin que se expongan en la misma, la argumentacion,
      los criterios o razones facticas que permitan en cualquier
      analisis, llegar a dichas conclusiones, de manera que el
      razonamiento sea completamente transparente en cuanto a la
      valoracion de los documentos presentados con la solicitud.

V.    Consecuente con los expuesto en materia de Licencias de Exploracion
      ha de entenderse:  Que el texto y el espiritu con que se emitio la
      Ley de Mineria, tal como se dejo establecido en el considerando I y
      articulo 8 y 9 de la misma, fue la de otorgar Licencias de
      Exploracion y subsiguiente concesion para la Exploracion de
      Minerales, a aquellas empresas que realicen esa actividad mediante
      la aplicacion de sistemas modernos que permitan el aprovechamiento
      integral de los minerales, habiendo condicionado como requisito
      para adquirir derechos mineros, la idonidad; determinado como
      idoneas quienes comprobaran tener capacidad tecnica y capacidad
      financiera para desarrollar proyectos mineros:  que al revisar los
      documentos presentados por el apelante como prueba, son nuevo plan
      de trabajo de proyecto de exploracion Nueva Esparta, programa de
      exploracion del proyecto minero, el programa a desarrollar en los
      cuatro anos en cuatro etapas, una por ano:  carta y resumen de
      Estados Financieros, informe de Contador Publico de la inversion,
      costos, y gastos efectuados desde el 01 de enero de 1999 al 30 de
      junio de 2003, Balance y Estados Financieros certificados por

      Auditor Publico, documentacion que tiene valor probatorio.
      Respecto a la capacidad tecnica presenta los nombres de empresas
      con cartas compromiso de que trabajaran en la exploitacion
      curriculun vitae de los tecnicos que participaran en el proyecto.
      De lo antes expuesto se concluye que la empresa solicitante si
      tiene un proyecto de exploracion geologica para un area con
      antecedentes mineros, y cuenta con personal tecnico con capacidad
      para desarrollar el proyecto, por lo que este Ministerio considera
      que la Sociedad solicitante cumple con las exigencias que  al
      efecto establece la Ley en el articulo 9, como es el tener
      capacidad tecnica y financiera para desarrollar el proyecto minero
      y resuelve ha lugar al recurso interpuesto.

Por tanto,

En uso de mis facultades legales, y con base a lo establecido en el Art.
45 de la Ley de Mineria y las consideraciones expuestas.
