The Commerce Insurance Company Estimates Pro Forma Impact of the 
Latest Massachusetts Residual Market Reform Proposal

The Commerce Insurance Company, a wholly owned subsidiary of The 
Commerce Group, Inc. (NYSE: CGI), is updating its estimate of the 
financial impact of the proposed reform of the residual market system 
for personal automobile insurance in Massachusetts to reflect changes 
in the rules being proposed.

Background of Regulatory Reform; Prior Commerce Disclosure

As we described in our Quarterly Report on Form 10-Q filed for the 
second quarter of 2004, the Massachusetts Commissioner of Insurance 
(the "Commissioner") issued a letter in April instructing Commonwealth 
Automobile Reinsurers ("CAR") to develop and submit to her rules for 
the reform of the residual market system.  On June 29, 2004, CAR 
proposed to the Commissioner a set of changes to the CAR Rules of 
Operations (the "Initial Reform Proposal").  Under the Initial 
Proposal, the first phase of the reform would have been effective for 
the period from July 1, 2004 through December 31, 2004.  Commerce 
estimated, as we disclosed in our Quarterly Report on Form 10-Q for 
the period ended June 30, 2004, that we would have incurred additional 
expenses for the final six months of 2004 of approximately $2.4 
million before taxes, and an additional expense in 2005 of 
approximately $1.2 million before taxes, all attributable to the first 
phase of the reform, if the Commissioner had adopted all of the rule 
amendments entirely as proposed by CAR for that phase.  At that time, 
we were unable to estimate the financial impact of the Initial Reform 
Proposal with respect to the rules proposed for 2005 and beyond.  The 
Commissioner, however, did not approve the Initial Reform Proposal.

Revised Reform Proposal

On August 27, 2004, the Commissioner directed CAR to submit to her a 
revised proposal for the reform of the residual market system.  CAR 
submitted its revised proposal on September 24 and amended it on 
October 8, 2004 (together, the "Revised Reform Proposal").  The 
Commissioner has scheduled a public hearing to be held at the Division 
of Insurance ("DOI") on October 29, 2004, to hear testimony regarding 
the Revised Reform Proposal. We cannot predict whether the 
Commissioner will approve the Revised Reform Proposal in substantially 
the form as recommended by CAR.

Residual Market Reform

Elimination of All or a Substantial Portion of 2004 Transition.  The 
Revised Reform Proposal does not include an initial transition phase 
for the period from July 1, 2004 through December 31, 2004, but the 
rules in the Revised Reform Proposal may apply for the month of 
December of 2004 if, during the month of November, the Commissioner 
approves the rules as proposed.

Accordingly, we now estimate that the proposed reform of the residual 
market will not result in our incurring $3.6 million of additional 
total expense before taxes for the eighteen month period ended 
December 31, 2005, as previously disclosed.  Rather, if during 
November the Commissioner approves the Revised Reform Proposal 
entirely as recommended by CAR effective December 1, 2004, we 
estimate that our additional expense, if any, for the next 15 months 
would be approximately $600,000 before taxes.

Overview of Revised Reform Proposal.  The Revised Reform Proposal 
would call for the current residual market pool to be divided into 
two components - the first comprising high loss ratio exclusive 
representative producers or "ERPs" and the second comprising other 
than high loss ratio ERP business and business ceded to the residual 
market from voluntary agents.  We expect that all insurers would be 
required to cede to CAR all business written by the high loss ratio 
ERPs, including business currently able to be retained voluntarily, 
although the Proposal does not address this point specifically. CAR 
would apportion the underwriting results of the high loss ratio ERP 
pool among all insurers based on each insurer's voluntary agent 
market share for the previous year.  The CAR residual market deficit 
from other than high loss ratio ERPs and business ceded to the 
residual market from voluntary agents will result in a smaller pool 
and be shared by insurers in substantially the same manner as is 
currently in effect for the total residual market pool.  While CAR 
has proposed different utilization formulas and credit values going 
forward, we expect that those changes will have no material net 
impact on Commerce's overall participation ratio for this second 
pool.  For a complete description as to how participation ratios are 
currently calculated, please refer to our 2003 Annual Report filed on 
Form 10-K under the CAR section of Part 1, Item 1.

The Revised Reform Proposal would also require, for the period 
beginning January 1, 2005, that each company with a 2003 market share 
of 7% or more service the business written by high loss ratio ERPs.  
In exchange, those servicing carriers would receive an increased 
expense reimbursement fee and an opportunity to earn bonuses for 
improvements in the loss ratio of those ERPs.  CAR estimates that 
Commerce's share of the high loss ratio ERP pool will be 
approximately 39.8%, given that Commerce and five other insurers will 
service the 2005 business of high loss ratio ERPs.  Companies with 
less than 7% total market share may become servicing carriers if they 
so request and are approved by the Commissioner.  If there are more 
than six carriers servicing the high loss ratio ERP business, the 
percentage of this pool that we service will be reduced.  Lastly, the 
Revised Reform Proposal contemplates the introduction of an assigned 
risk plan beginning in 2006 for a segment of the business and for all 
business by 2008.

Pro Forma Impact of Revised Reform Proposal on 2003 Results

We believe that it is premature to estimate the impact of the Revised 
Reform Proposal on our future financial results because of uncertainties 
relating to the rates that the Commissioner will approve for personal 
automobile insurance for 2005, and our inability at this time to predict 
reasonably the strategies that Commerce and other companies may pursue in 
the proposed residual market system that could have a material impact on 
the residual market deficit, the voluntary agent marketplace, insurers' 
participation ratios, and other important factors.

CAR, however, has provided some guidance as to what effect the Revised 
Reform Proposal would have had if it had been in effect for the 2003 policy 
year, which is the most recent policy year for which substantially complete 
CAR data is available.  Based on information made available by CAR, if we 
apply, to our 2003 policy year results, the revised residual market rules 
entirely as recommended in the Revised Reform Proposal for January 1, 2005 
and beyond, we estimate that we would have realized a favorable impact in 
the amount of $3 million before taxes for our fiscal year ended December 
31, 2003.

Based on the information made available by CAR in their filing with the 
Commissioner, our estimate is based on CAR's calculation that, had the 
Revised Reform Proposal been in effect for the 2003 policy year, the total 
CAR deficit would have been approximately $424 million, of which $295 
million would have been attributable to high loss ratio ERPs.  CAR's 
current projected policy year 2003 deficit is $322 million.  The increase 
in the pro forma deficit is caused by both the expected mandatory cession 
of all high loss ratio ERP business and an increase in the expense 
allowance for servicing this business, as further noted below.  Using our 
year end 2002 voluntary agent market share of 26.4%, we estimate that our 
share of the total pro forma 2003 CAR deficit of $424 million would 
increase to $105 million versus our actual share of the CAR deficit, which 
amounted to $67 million. Approximately $78 million of that $105 million 
would be attributable to our share of the proposed high loss ratio pool, 
and the remainder would represent our participation in the non-high loss 
ratio pool's deficit.

We estimate that Commerce's increased share of the residual market deficit 
would be more than offset by a few other components of the Revised Reform 
Proposal.  First, CAR proposes to increase the expense allowance for 
servicing the high loss ratio ERPs from 28.8% to 46.2%, which would have 
generated an estimated additional $10 million income before taxes for the 
high loss ratio ERPs that we serviced in 2003, plus an estimated additional 
$19 million, after incremental costs and before taxes, for servicing 
additional high loss ratio ERPs that would be assigned to us as one of the 
six proposed designated servicing carriers.  Second, we would have realized 
in the 2003 policy year an estimated additional savings of $12 million 
before taxes as a result of the expected requirement that we cede all 
business written by high loss ratio ERPs, as compared to writing that 
business voluntarily.

For the reasons described previously, the actual impact that the Revised 
Reform Proposal may have on our operating results in 2005 or any future 
year may differ significantly from the pro forma impact on our 2003 
results.  We intend to review and, if necessary, revise our business 
strategies in response to these initiatives as they are implemented.  We 
cannot predict whether our efforts will be successful or whether the 
initiatives as implemented will affect our competitive position or 
financial performance other than as described above.

Forward Looking Statements

statements are qualified in their entirety by reference to the factors 
discussed throughout this press release and in our Forms 10-K and 10-Q, and 
other documents filed with the SEC. Among the key factors that could cause

*  potential rate filings;
*  heightened competition;
*  concentration of business within Massachusetts;
*  market disruption in Massachusetts, if competitors exited the 
   market or become insolvent;
*  dependence on our executive officers; and,
*  the economic, market or regulatory conditions and risks 
   associated with entry into new markets and diversification.

You should not place undue reliance on any forward-looking statement. The 
risk factors referred to above could cause actual results or outcomes to

of unanticipated events. New factors emerge from time to time, and it is 
not possible for us to predict which factors will arise. In addition, we 
cannot assess the impact of each factor on our business or the extent to 
which any factor, or combination of factors, may cause actual results to 
differ materially from those contained in any forward-looking statements.
