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, 2010.  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

     $404,840.75 as of March 31, 2010.  Commerce has renewed this

     promissory note as of March 31, 2010 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, 2010 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

               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.

          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 RESOLVED, 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, 2010, 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

     Robertson, husband and wife (M&R), the Machulak, Robertson & Sodos,

     (a)  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.

     (b)  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.

     (c)  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.

     (d)  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.

     (g)  Acknowledgment of collateral provided through March 31, 2010

          Commerce's Directors have on March 29, 2010 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, 2010,

          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.

Principal Amount:         $404,840.75

Initial Rate:             3.000% + prime rate, but not less than 16.000%

Date of Renewed Note:     March 31, 20010

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 Four Hundred Four Thousand Eight Hundred Forty and

75/100 Dollars ($404,840.75), together with interest, paid monthly, on

the unpaid principal balance from March 31, 2010, 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,

there is a lawsuit, including attorneys' fees, expenses for bankruptcy
