Mrs. Susan R. Robertson

River Hills, Wisconsin  53209

Dear Mr. Machulak and Mrs. Robertson:

At today's Commerce Group Corp. (Commerce) Directors' meeting, the
Directors were informed about the annual confirmation, disclosure and
status letter from Commerce, its subsidiaries, its affiliates, and the
Joint Venture, and to establish and confirm the amount due and the
collateral pledged along with any other Commerce obligations or
agreements made to John E. Machulak and Susan R. Robertson, husband and
wife (M&R) referred to as Lenders, as of Commerce's fiscal year ended
March 31, 2009.  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 M&R is
     $344,591.32 as of March 31, 2009.  Commerce has renewed this
     promissory note as of March 31, 2009 and a copy is attached (Exhibit
     A).  A schedule including all of the transactions pertaining to the
     activities relating to this Note during this fiscal year ended March
     31, 2009 is also attached (Exhibit A-1).  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.  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 M&R 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 M&R and
     Commerce will provide an annual accounting and confirmation letter.

     On May 9, 2005, Commerce's Directors authorized its Officers to
     issue renewed annual note(s) (Exhibit B of the May 9, 2005
     confirmation letter) 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.  However,
     beginning with the fiscal year which ended March 31, 2007, the
     Directors are including the following as Lender(s):  John E.
     Machulak and Susan R. Robertson, husband and wife (M&R), the
     Machulak, Robertson & Sodos, S.C. Law Firm (Law Firm), Circular
     Marketing, Inc. (CMI) and Edward A. Machulak as an individual (EAM).
     Therefore, the Directors have unanimously agreed to continue to
     embrace this 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

          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,

          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).

     As of March 31, 2009, the following parties are collectively and
     individually identified as the Lender(s): 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

2.   Collateral Pledged

     The following collateral has been previously assigned to certain
     Lenders, and from March 31, 2007 forward includes John E. Machulak
     and Susan R.  Robertson, husband and wife (M&R), the Machulak,
     Robertson & Sodos, S.C.  Law Firm (Law Firm), Circular Marketing,
     Inc. (CMI) and Edward A. Machulak as an individual (EAM) as of March
     31, 2007, pursuant to resolutions adopted by the Directors:

     (1)  Commerce/Sanseb Joint Venture (Joint Venture)

          Both Commerce and San Sebastian Gold Mines, Inc. have assigned
          all of the rights, title, claims, remedies and interest that
          each has in the Joint Venture to the Lenders.  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)
          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.  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 tax.  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.

          issued the Nueva Esparta Exploration Concession/License for a
          period of four years starting from the date following the

     (7)  Acknowledgment of collateral provided through March 31, 2009

          Commerce's Directors have on April 8, 2009 authorized and
          directed Commerce's Officers to assign all of the rights,
          titles, claims, remedies and interest in all of its assets that
          it has, including any assets owned by the Joint Venture, to
          GLSCO, ELM, the ELM RIRA, the SM RIRA, SM, and from March 31,
          2007 to include M&R, the Law Firm, CMI and EAM, collectively
          and individually referred to as Lenders, as additional
          collateral for all of the
          outstanding loans and obligations as of March 31, 2009,
          including all future advances of any kind.

3.   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, SM, and from March 31, 2007 to include M&R, the
     Law Firm, CMI and EAM, 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.

4.   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, SM and from March 31, 2007
     to include M&R, the Law Firm, CMI and EAM, 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.

5.   Guarantors

     This agreement further confirms that Commerce and all of the
     following are guarantors to the obligations due to M&R and to the
     loans made by the M&R 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, SM, and from March
     31, 2007 to include M&R, the Law Firm, CMI and EAM.  Reference is
     made to Exhibit 5 included in the April 9, 1990 confirmation letter.

6.   Re-Execution Agreement(s)

     In the event M&R deem that it is necessary or advisable for M&R 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 M&R.  Commerce also acknowledges that Commerce may be
     liable to pay certain costs related to any of the transactions
     entered into with M&R.  If at a later date M&R determine that an
     error has been made in the payment of such costs to M&R, then M&R
     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 M&R's written request.   The failure of Commerce
     to comply with Commerce's obligation(s) hereunder shall constitute a
     default and shall entitle M&R 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).

7.   Omissions

     Commerce believes that it has included all of its obligations,
     monies due and has listed all of the collateral due to M&R, 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,

                           RENEWED PROMISSORY NOTE


Borrower: Commerce Group Corp.             Lender:  John E. Machulak and
          6001 North 91st Street                    Susan R. Robertson
          Milwaukee, WI  53225                      1400 West Good Hope Road
                                                    Milwaukee, WI  53209

Principal Amount:         $344,591.32
Initial Rate:             3.000% + prime rate, but not less than 16.000%
Date of Renewed Note:     March 31, 2009

PROMISE TO PAY.  COMMERCE GROUP CORP. ("Borrower") promises to pay to
JOHN E.  MACHULAK AND SUSAN R. ROBERTSON, husband and wife ("Lender"), or
order, in lawful money of the United States of America, the principal
amount of Three Hundred Forty Four Thousand Five Hundred Ninety One and
32/100 Dollars ($344,591.32), together with interest, paid monthly, on
the unpaid principal balance from March 31, 2009, 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 two 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 as of this
date is 3.250% per annum.  The interest rate to be applied to the unpaid
principal balance of this Note will be at a rate of 2.000 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.
