                                    SUMMARY

  This summary highlights information contained elsewhere in this prospectus
supplement and may not contain all of the information investors should consider
before investing in the senior notes. You should read the entire prospectus
supplement and accompanying prospectus carefully, especially the "Risk Factors"
section beginning on page 5 of the accompanying prospectus, and the documents
to which we refer you in the section of the accompanying prospectus called
"Where You Can Find More Information."

               Mutual Risk Management Ltd. and Mutual Group Ltd.

  We provide risk management services to clients in the United States, Canada
and Europe that seek alternatives to traditional commercial insurance for risk
exposures. In addition, we provide financial services to offshore mutual funds
and other companies. MRM is a Bermuda-based insurance holding company that was
incorporated in 1977. Mutual Group is a Delaware-based holding company that was
incorporated in 1979. We primarily focus on the "alternative market," which
involves clients self-insuring a significant amount of their loss exposure and
transferring only the unpredictable excess risk to insurers. Although revenue
earned from premiums is substantial, our principal source of profits is from
fees received for the various insurance and other services provided to clients
in connection with our programs. Income from fees is derived from four distinct
business segments:

  Program Business--The largest of our business segments. In this segment, we
  replace traditional insurers as the conduit between producers of specialty
  books of business and reinsurers wishing to write that business. We provide
  a range of services for a fee and the underwriting profit is shared between
  the producer and the reinsurers. The Program Business accounted for 53% of
  fee income for the year ended December 31, 1999 and 55% of fee income for
  the quarter ended March 31, 2000.

  Corporate Risk Management--Our original business segment. Corporate Risk
  Management involves providing services to businesses and associations
  seeking to insure a portion of their risk in a loss sensitive alternative
  market structure. We earn our fees by designing and implementing risk
  financing and loss control programs for medium-sized and large companies
  that seek to insure a portion of their insurable risk. Corporate Risk
  Management accounted for 28% of fee income for the year ended December 31,
  1999 and 23% of fee income for the quarter ended March 31, 2000.

  Specialty Brokerage--Our Specialty Brokerage segment specializes in placing
  reinsurance for captive insurance companies, placing coverage with excess
  liability and corporate officers' and directors' liability carriers and
  placing reinsurance in connection with our Program and Corporate Risk
  Management businesses. Specialty Brokerage accounted for 8% of fee income
  for the year ended December 31, 1999 and 8% of fee income for the quarter
  ended March 31, 2000.

  Financial Services--Our Financial Services segment started in 1996 with the
  acquisition of The Hemisphere Group Limited. The Financial Services segment
  provides administrative services to offshore mutual funds and other
  companies and offers a proprietary family of mutual funds as well as asset
  accumulation life insurance products for the high net worth market.
  Financial Services accounted for 11% of fee income for the year ended
  December 31, 1999 and 14% of fee income for the quarter ended March 31,
  2000.

  The structure of our programs places most of the underwriting risk with the
client or our reinsurers. For regulatory and other reasons, however, we are
required to assume a limited amount of risk. We seek to limit our risk to the
minimum level feasible. This approach to risk distinguishes us from typical
property/casualty companies that assume significant levels of underwriting risk
as part of their businesses. We do not seek to earn income from underwriting
risk, but rather from fees for services provided.

  MRM's principal executive offices are located at 44 Church Street, Hamilton
HM 12 Bermuda and its telephone number is (441) 295-5688. Mutual Group's
principal executive offices are located at One Logan Square, Suite 1500,
Philadelphia, Pennsylvania 19103, and its telephone number is (215) 963-1200.

  The net proceeds will be approximately $148,150,000 from the sale of the
senior notes, less estimated expenses incurred by us in connection with this
offering. The net proceeds will be used to repay amounts outstanding under a
bridge loan facility dated December 6, 1999 between MRM, its subsidiaries,
Prudential Securities Credit Corp. and Bank of America, N.A. Amounts
outstanding under the facility bear interest at LIBOR plus 0.75% and mature on
September 6, 2000. Borrowings under the facility were used to provide
additional capital to our U.S. insurance company subsidiaries and to
repurchase convertible debentures of MRM.

                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS

  The following discussion contains sections from "Management's Discussion and
Analysis of Financial Condition and Results of Operations," the full text of
which is included in our Annual Report on Form 10-K, as amended in our Annual
Report on Form 10-K/A, for the year ended December 31, 1999 and our Quarterly
Report on Form 10-Q for the period ended March 31, 2000, which are
incorporated by reference into this prospectus supplement. The following
discussion should be read in conjunction with MRM's consolidated financial
statements and the accompanying notes, which are also incorporated by
reference into this prospectus supplement.

Consolidated Results of Operations

 For the Quarters Ended March 31, 2000 and 1999

  The results of operations for the first quarter of 2000 reflect improvement
in fees, operating income, profit margins and return on equity over the
results for our last two quarters. However, comparisons to the first quarter
of 1999 continue to reflect the decline in operating results that took place
in the second half of last year. Net income available to common shareholders
was $6.9 million or $0.17 per common share on a diluted basis for the first
quarter of 2000, as compared to $18.8 million or $0.40 per diluted share in
1999, as shown in the tables below.

 Program Business

  Program Business involves replacing traditional insurers and acting as a
conduit between producers of specialty books of business and reinsurers
wishing to write that business. The segment accounted for 55% of total fee
income in the first quarter of 2000 compared to 50% in the corresponding 1999
period. Program business fees increased by 9% in the first quarter of 2000 to
$25.0 million as compared to $22.9 million in 1999. This resulted from the
continued expansion of this segment through the growth of existing programs.
Profit margins were 26% in the first quarter of 2000 as compared to 36% in
1999 as a result of high operating expenses. Margins improved, however, from
the previous quarter's level of 8%.

  Gross premiums written increased 45% to $335.2 million for the first quarter
of 2000 as compared to $231.9 million in 1999, primarily as a result of the
growth within the Program Business segment. Program Business generally
involves greater premium volume per unit than Corporate Risk Management
business. Premiums earned increased 44% to $55.9 million in the first quarter
of 2000, as compared to $38.8 million in the corresponding 1999 period. These
increases in premiums earned were also primarily due to the growth within the
Program Business segment.

 Corporate Risk Management

  Corporate Risk Management, our original business segment, involves providing
services to businesses and associations seeking to insure a portion of their
risk in a loss sensitive alternative market structure. This segment accounted
for 23% of total fee income in the first quarter of 2000, down from 33% in
1999. Corporate Risk Management fees decreased by 31% in the first quarter of
2000 to $10.4 million. Profit margins were 23% in the first quarter of 2000 as
compared to 44% in 1999 as a result of the decline in fees, which was not
offset by a corresponding decline in operating expenses. Margins improved,
however, from the previous quarter's level of 14%. The level of Corporate Risk
Management fees in the first quarter of 1999 was higher than the remainder of
the year. We continue to expect that a firming of prices generally will begin
to improve the sale of corporate accounts later this year.

 Specialty Brokerage

  Our Specialty Brokerage business segment provides access to alternative risk
transfer insurers and reinsurers in Bermuda and Europe. The segment produced
$3.8 million of total fee income in the first quarter of 2000, representing 8%
of total fee income. Specialty Brokerage fees grew by 22% in the first quarter
as a result of increased business placed in Bermuda and London. Profit margins
declined to 35% in the first quarter of 2000 as compared to 49% in the
corresponding 1999 period.

 Financial Services

  Financial Services, our newest business segment, provides administrative
services to offshore mutual funds and other companies and offers a proprietary
family of mutual funds as well as asset accumulation life insurance products
for the high net worth market. The segment accounted for 14% of total fee
income for the first quarter of 2000. Fees from Financial Services increased
in the quarter by 36% to $6.0 million over the 1999 corresponding period,
primarily as a result of an increase in the number of mutual funds under
administration from 205 to 303. Profit margins in the Financial Services
segment have been adversely affected since 1998 by the previously announced
revised executive incentive plan and staff expansion costs to service new
business, but increased to 22% for the first quarter of 2000. Excluding the
effect of the revised executive incentive plan, which will end in December
2000, the profit margins in this segment would have been 27% for the quarter
as compared to 15% in 1999.

 Investment Income

  Gross investment income increased by $4.8 million, or 55%, to $13.6 million
in the first quarter of 2000 over 1999. Net investment income increased by 74%
to $12.6 million in the first quarter of 2000 as compared to $7.2 million in
1999. Included in gross and net investment income for the first time is $3.7
million from a special purpose entity, Endeavour Real Estate Securities Ltd.
Our Financial Services segment established Endeavour to offer offshore
investors an opportunity to invest in U.S. real estate investment trusts.
Endeavour has attracted over $220 million from investors through March 31,
2000. This investment income was offset by $1.4 million of realized losses,
$1.9 million of interest expense, $0.9 million of operating expenses and
$(0.8) million of minority interest in the quarter. The significant assets and
liabilities of Endeavour are shown as separate line items in our Consolidated
Balance Sheet as Equity Investments held by Special Purpose Entity and
Minority Interest in Special Purpose Entity. In addition, we increased our
bridge loan facility in late December 1999 by $110 million, which was
contributed to our U.S. insurance companies. This increased capitalization of
the U.S. insurance companies accounted for most of the remaining increase in
investment income. Investment yields, excluding Endeavour, were 6.9% in the
first quarter of 2000 as compared to 6.7% in the corresponding 1999 period.

  The breakdown of expenses for the quarters ended March 31, 2000 and 1999 is
set forth in Table IV.

</TABLE>

  Operating expenses increased 19% to $34.6 million for the first quarter of
2000 compared to $29.1 million in 1999. The increase in operating expenses was
attributable to an increase in personnel and other expenses to service our
existing businesses, the effect of recent acquisitions and the $0.9 million of
operating expenses from Endeavour.

                                      S-9
<PAGE>


  The fluctuations in total insurance costs are the direct result of the
fluctuations in premiums earned during the quarter. In the quarter, however,
the net underwriting loss increased to $3.3 million compared to $0.9 million
in 1999 as a result of increased legal costs and premium audit costs as well
as an increase in the loss ratio on our participation in our reinsurance
treaty. Interest expense increased $4.4 million over the corresponding 1999
period as a result of Endeavour, which added $1.9 million in the quarter, and
the bridge loan financing, offset by a reduction in debenture interest.

  The effective tax rate was 8.6% in the first quarter of 2000 compared to
9.7% in the corresponding 1999 period. These effective tax rates were lower
than the expected federal income tax rate in the United States of 35% plus
state income taxes due to increased earnings outside of the United States and
our investment in tax-exempt municipal securities, partially offset by state
income taxes and foreign taxes.


 For the Years Ended December 31, 1999, 1998 and 1997

  Net income decreased by 22% to $50.4 million in 1999 from $64.5 million in
1998, which was in turn a 30% increase over the $49.5 million earned in 1997.
The decline in earnings in 1999 was due to slower growth in the Program
Business segment and a decline in Corporate Risk Management offset, in part,
by growth in Specialty Brokerage and Financial Services. Earnings in 1999 were
also adversely affected by the third quarter provisions related to net losses
incurred on terminated programs of $8 million, net of tax. The increase in
1998 earnings was primarily attributable to the growth experienced in the
Program Business and Financial Services segments.

  All prior period results have been restated to reflect a pooling of
interests following the acquisition of Captive Resources, Inc.

  The growth of fee income and premiums earned over the past three years has
been primarily due to the strong growth in Program Business, which has
compensated for the decline in those years in Corporate Risk Management
business.

  Overall, pre-tax profit margins on fee income fell in 1999 to 28% compared
to 35% in 1998 and 37% in 1997.

 Program Business

  Program Business involves replacing traditional insurers and acting as the
conduit between producers of specialty books of business and reinsurers
wishing to write that business. Program Business accounted for 53% of our
total fees for 1999 compared to 52% in 1998 and 41% in 1997. This growth
resulted from expansion of this business as a result of reinsurers' increased
appetite for premium volume in the soft market in those years. Fees earned on
individual program accounts are more likely to grow compared to corporate
accounts because new policy holders are constantly being added in each
program. Program Business also has historically had a higher retention rate
than Corporate Risk Management. Pre-tax margins in this segment were 28% for
1999 compared to 40% in 1998 and 39% in 1997. The second half of 1999 saw a
decline in the growth rate and margins in this segment as a result of a
decline in premium rates, especially at our underwriting management
subsidiary, Small Business Underwriters.

 Corporate Risk Management

  Corporate Risk Management, our original business segment, involves providing
services to businesses and associations seeking to insure a portion of their
risk in a loss sensitive alternative market structure. This segment, which
accounted for 28% of total fee income for 1999 compared to 33% in 1998 and 45%
in 1997, has been the most affected by the extremely soft insurance market
cycle for commercial risks. Corporate Risk Management fees decreased in both
1998 and 1999 due to these soft market conditions. The number of Corporate
Risk Management accounts decreased in 1999 to 103 from 118 in 1998 which was
in turn down from 154 in 1997. Profit margins fell in 1999 to 32% compared to
39% in 1998 and 37% in 1997. The 1999 profit margin was negatively impacted by
the decrease in fees on Program Business because certain operating expenses
are not separately identified by segment, but rather are apportioned by fee
income.

  Historically, workers' compensation has been the major line of business
written by us in both our Corporate Risk Management and Program Business
segments. Generally, competition for workers' compensation business has
increased in recent years and the resulting under-pricing of workers'
compensation risks by traditional insurers has reduced the incentive for
insureds to enter "alternative market" vehicles such as those offered by us in
our Corporate Risk Management segment. However, we are beginning to see price
increases in a number of lines, particularly in California workers'
compensation and in accident and health across the U.S., resulting in
increased submission activity.

  Despite these competitive forces, we were successful in increasing our
business as a result of the attractiveness of Program Business in this soft
reinsurance market. We continued to diversify our business to reduce our
reliance on the workers' compensation market and were successful in doing so.
As a percentage of total fee income, workers' compensation accounts decreased
from over 80% at December 31, 1994 to 53% at December 31, 1999 as a result of
our writing accounts comprising other lines of coverage such as accident and
health, commercial, auto liability, auto physical damage and other liability
coverages as well as the expansion of our Financial Services segment.

 Specialty Brokerage

  Our Specialty Brokerage business segment provides access to alternative risk
transfer insurers and reinsurers in Bermuda and Europe. Fees in this segment
grew by 52% in the year as a result of increased business placed in Bermuda
and London. Profit margins improved to 38% from 25% in 1998 and 31% in 1997
primarily as a result of the increased revenues.

 Financial Services

  Financial Services, our newest business segment, provides administrative
services to offshore mutual funds and other companies. This segment also
includes our family of proprietary mutual funds as well as asset accumulation
life insurance products for the high net worth market. Financial Services
accounted for 11% of

                                     S-11
<PAGE>

total fee income for 1999, up from 9% for 1998 and 7% in 1997. Fees from
Financial Services increased primarily as a result of an increase in the
number of mutual funds under management from 129 in 1997 and 195 in 1998, to
279 in 1999. Profit margins decreased from 26% in 1997 to 4% in 1998, and
improved to 7% in 1999. Margins in the Financial Services segment were
adversely affected in both 1998 and 1999 by the previously announced revised
executive incentive plan implemented in 1998. The effect of this revised
executive incentive plan will continue through 2000. Excluding the effect of
the revised executive incentive plan, the profit margins in this segment would
have been 17% and 18% for the years ended December 31, 1999 and 1998
respectively.

 Underwriting

  We generally require each Corporate Risk Management client to indemnify us
against an underwriting loss and the client normally provides collateral for
at least the difference between the funds available in that client's account
and the level of expected losses as actuarially determined by us, although in
certain circumstances the collateral level is below the level of expected
losses. This is also the case for Program Business clients who participate in
the IPC Programs. For Program Business clients that do not participate in the
IPC Programs, reinsurance protection is purchased by us to minimize our
underwriting risk.

  We face credit exposure in the event that losses exceed their expected level
and the client is unable or unwilling to honor its indemnity to us. We also
face credit exposure on both Program and Corporate Risk Management Business if
our clients or brokers fail to pay the premium due, through failure of the
program manager or broker to properly administer the program and through
failure of reinsurers to honor their obligations. Lastly, we are exposed to
underwriting risk if losses incurred under programs exceed their reinsurance
limits or where there is a gap in purchased reinsurance coverage.

  We have established provisions for losses as a result of these exposures for
certain clients. These provisions, which totaled $18.0 million at December 31,
1999, $7.3 million in 1998 and $5.6 million in 1997, reduced the level of fee
income in each year by $3.1 million, $.9 million and $1.1 million,
respectively. These provisions also adversely impacted the underwriting
results in each year by $7.6 million, $.8 million and $0 in 1999, 1998, and
1997, respectively, due to programs where losses exceeded reinsurance limits
and uncollected premiums. The increase in provisions from 1998 to 1999 related
primarily to provisions established in the third quarter on a number of
terminated programs. The 1999 provisions are net of a reinsurance recovery of
$14.7 million under a contingency excess of loss policy. The increase in the
number of accounts and their inherent growth in premium volume, the increase
in the clients' aggregate retentions since 1991, the amounts recoverable from
reinsurers, which amounted to $2.0 billion at December 31, 1999 and $1.3
billion at December 31, 1998, in addition to competitive factors which have
limited the amount of collateral that clients are willing to provide, have
significantly increased our exposure to such losses. We evaluate the financial
condition of our clients, brokers and reinsurers to minimize our exposure to
losses from insolvencies.

  During 1999, we initiated binding arbitration proceedings for the payment of
reinsurance recoverables from a number of reinsurers who have withheld payment
due to us. The amounts due to us relate primarily to reinsurance on workers'
compensation coverage. We believe we will ultimately prevail in such
arbitrations and any related actions that may arise.

  Premiums earned increased by 78% in 1999, 21% in 1998 and 49% in 1997. These
increases were attributable to the shift in business from the Corporate Risk
Management segment to the Program Business segment and the strong growth
within this segment. Program Business usually involves higher premiums than
business derived from the Corporate Risk Management segment due to new
policies constantly being added by agents. Premiums earned represent the net
premiums retained by us on which we bear underwriting risk. We believe that
both the volatility of underwriting profit or loss and the probability of
experiencing a severe underwriting loss are less than would ordinarily be
expected for a traditional property/casualty insurer, due to the nature of the
business written by us and the structure of our reinsurance. In the past, the
level of premiums

                                     S-12
<PAGE>

earned has been closely matched by the level of total insurance costs,
resulting in small amounts of underwriting loss as a percentage of premiums
earned. However, in 1999, losses incurred under certain programs exceeded
their reinsurance limits and caused underwriting losses to be higher than
historical levels. The fact that premiums earned have historically matched
total insurance costs means that even a significant fluctuation in premiums
earned should have a relatively insignificant impact on our net income.

  Included in premiums earned are assigned risk premiums of $1.8 million in
1999 as compared to $2.5 million in 1998 and $8.4 million in 1997. The
underwriting losses associated with these assigned risk premiums, together
with other charges imposed by certain states on voluntary insurers such as
Legion Insurance to support involuntary market losses, also referred to as
residual market loads, are passed on by Legion Insurance to clients' accounts.

  Other than the risks described above, our principal exposure to underwriting
loss exists in relation to the premium associated with our retention of a
portion of the specific and aggregate excess risk on each client's account. On
this retained excess risk we may experience volatility in underwriting
results. The portion of our premiums earned which relate to this risk was $4.1
million in 1999 as compared to $2.1 million in 1998 and $2.2 million in 1997,
representing 2%, 2%, and 3% of premiums earned in 1999, 1998 and 1997,
respectively. We incurred an underwriting loss of $17.5 million in 1999, $2.4
million in 1998 and $1.5 million in 1997. The large loss in 1999 was
principally due to the provisions on terminated programs described above.
These underwriting losses were also a result of retained risk on our treaties
and underwriting expenses. We take 100% of the risk within the first $1.25
million layer of the aggregate excess exposure on our main treaty up to a
deductible amount equal to 1.5% of our gross premiums and 10% of the risk over
a loss ratio of 120%, in the event that the loss ratio for the first layer
exceeds 120%. We take no share of the risk in the layer $3.75 million excess
of $1.25 million per account. The maximum retention for specific excess losses
is 10% of $.75 million excess of $.25 million per occurrence.

 Investment Income

  Gross investment income increased by $.8 million in 1999 to $35.9 from $35.1
million in 1998 and $30.0 million in 1997 as a result of increases in gross
invested assets. Net investment income, after adjusting for investment income
which is payable to others, increased by 14% to $33.6 million in 1999 from
$29.6 million in 1998 and $26.6 million in 1997. The increase in net
investment income for 1999 was due, in part, to the inclusion of investment
income from one of our programs, accounted for as claims deposit liabilities,
which added $2.8 million for the year. Net invested assets increased $88
million or 20% to $527 million in 1999 from $439 million in 1998 and $402
million in 1997. The yield on these assets remained steady at 6.9% in 1999 and
1998, which was up slightly from 6.7% in 1997. Our investment income is
produced through the investment of our capital funds, long term debt, other
funds held representing amounts due others and reserves held by us for
unearned premiums and unpaid losses.

  The breakdown of expenses for each of 1999, 1998 and 1997 is set forth in
Table III.

  The increases in total insurance costs are typically the direct result of
the increases in premiums earned during the relevant period. However, total
insurance costs during 1999 exceeded the increase in premiums earned. During
the year, we established a provision related to net losses incurred on a
number of terminated programs of $8 million net of tax. This resulted in a
$12.3 million increase in losses and loss expenses incurred offset by a $4.3
million reduction in income taxes. Losses incurred also increased as a direct
result of the decreased use of large deductible policies and the increase in
Program Business. The 27% decrease in acquisition costs from 1997 to 1998 was
due to the reduction in the number of deductible programs, which have high
expense levels, the loss of one large account that was fully retained and
reduction in expenses charged by the assigned risk pools.

  The primary factors responsible for the increases in operating expenses
were: (i) the increased cost of administering our highly regulated policy-
issuing subsidiaries, as the volume of policies issued increased;
(ii) increased personnel costs in all areas, caused by an increase in the
number of full time employees from 743 in 1997 to 934 in 1998 to 1,143 in
1999, resulting from the growth of our businesses as well as the impact of our
growth in revenues and profits on employee bonus plans; (iii) the acquisitions
of Small Business Underwriters Inc., Hugo Trust Company, Avreco Ltd. and
Capital Management (Bermuda) Ltd.; and (iv) the Hemisphere expansions to
Boston and Ireland.

  The charges for income taxes represent effective tax rates of 17.6%, 11.7%
and (.7)% in 1997 through 1999, respectively. The reduced tax rate in 1998 and
1999 was due to increased earnings outside of the United States. The tax rate
in 1999 was reduced further by the provisions on terminated programs. These
factors, plus interest earned on tax-fee municipal securities and the tax
benefit derived from the exercise of employee stock options, were the major
causes of the difference between the expected federal income tax rate in the
United States of 35% plus state income taxes and our effective rates in the
year. The Legion Companies, as insurance companies in the United States, are
subject to income tax on an accelerated basis and, as a result, a deferred tax
benefit was carried on the consolidated balance sheets of $4.2 million in 1999
and $.9 million in 1998.

Liquidity and Capital Resources

 Investments

  At December 31, 1999, the market value of our total marketable investments
was $607 million, as compared to $580 million at December 31, 1998. In
accordance with SFAS 115, investments available for sale are reported at fair
market value with unrealized gains and losses included as a separate component
of shareholders' equity. These investments generally consist of investment
grade fixed-income securities that we believe are readily marketable and could
be liquidated to meet cash requirements, if necessary.

 Cash Flow

  Cash flow from operations has historically provided us our principal source
of liquidity. We have continued to produce a positive cash flow with $20.6
million of cash provided from operations during 1999, as compared to $62.4
million in 1998 and $56.4 million in 1997. Cash flow in 1999 was adversely
affected by delays in recovering reinsurance payments in our Program Business
segment but improved in the second half of 1999 from the first and second
quarters. We produced a positive cash flow in the first quarter of 2000 of
$0.1 million.

  In 1999, we established a $250 million bridge loan facility, of which $117
million was outstanding at December 31, 1999 and $217 million was outstanding
at March 31, 2000. During 1999, we made an additional contribution to the
policyholders' surplus of our U.S. insurance companies in the amount of $110
million from this facility. We expect to refinance this bridge loan facility
with the proceeds from this offering and additional borrowings under a
revolving credit facility that we are currently negotiating.

  As of December 31, 1999, we had repurchased $14 million face amount of our
convertible exchangeable subordinated debentures due 2015 at a cost of
$6.3 million. During the first quarter of 2000, we repurchased convertible
debentures representing a principal amount of $222 million in the open market
at a cost of $101.3

                                     S-14
<PAGE>

million. The repurchased debentures were convertible into 4.8 million common
shares and their repurchase resulted in a one-time extraordinary loss of
approximately $4.3 million, net of tax.

  We believe that funds generated from operations and available credit will be
sufficient to finance our current operations and to make payments under our
debt facilities, including the senior notes.

 Insurance Operations

  At the end of 1999 and 1998, 61% and 56% of our total marketable investments
were held by our policy-issuing subsidiaries in the United States. These
companies are restricted by regulation in the amount of dividends they can pay
without prior regulatory approval to $35.0 million in 2000 (based on 1999
results) and will continue to face these restrictions in the future. During
1999, they paid a dividend of $7 million. They are also required to maintain
certain deposits with or supply letters of credit to regulatory authorities
which totaled $166 million at December 31, 1999 ($59 million of deposits and
$107 million of letters of credit) as compared to $152 million at December 31,
1998 ($60 million of deposits and $92 million of letters of credit).

  A widely accepted factor used by regulators and rating agencies in
evaluating insurance companies is the ratio of net premiums written to
policyholders' surplus which is an indication of the degree to which an
insurer is leveraged. Because of the low level of net premiums written, the
Legion Companies have produced a relatively low ratio on this basis of
approximately 0.6:1 in 1999, 0.5:1 in 1998 and 0.4:1 in 1997 and should
continue to produce relatively low ratios in the future. Due to the nature of
our operations, a more appropriate indication of leverage is the ratio of
gross premiums written to policyholders' surplus, which amounted to 3.6:1 in
1999, 3.6:1 in 1998 and 3.0:1 in 1997. The National Association of Insurance
Commissioners, also referred to as the NAIC, has established that an "unusual
value" for this ratio would be 9:1 or higher. We have adopted a policy that
this ratio should not exceed 4:1.

  The NAIC has adopted a risk-based capital, also referred to as a RBC,
formula to be applied to all property/casualty insurance companies. The
formula measures capital and surplus needs based on an insurance company's
products and investment portfolio and is to be used as a tool to identify
weakly capitalized companies. An insurance company that does not meet the
threshold RBC measurement standards could be required to reduce the scope of
its operations and ultimately could become subject to statutory receivership
proceedings. At December 31, 1999, our policy-issuing subsidiaries met the RBC
requirements with a combined required risk-based capital of $121.0 million and
an actual adjusted capital of $347.4 million.

 Shareholders' Equity

  Shareholders' equity increased to $361 million at March 31, 2000 from $358
million at December 31, 1999 primarily as a result of net income in the
quarter, less dividends paid and change in unrealized losses. Shareholders'
equity increased 4% to $358 million at December 31, 1999 from $343 million at
December 31, 1998. This increase was attributable to net income in 1999, less
dividends paid, plus the value of shares issued on the exercise of employee
stock options, and the conversion of debentures. During 1999, the total number
of common shares outstanding decreased to 41,205,191 from the 1998 level of
42,205,596, mainly as a result of our repurchase of 2.6 million shares in the
fourth quarter at an average price of $11.31 per share. This decrease in
common shares outstanding for the year was partly offset by the conversion of
debentures and the exercise of employee stock options.

 Total Assets

  Total assets increased to $4.3 billion at March 31, 2000. Assets held in
separate accounts, which are principally managed assets attributable to
participants in our IPC Programs, accounted for approximately 17% of total
assets at March 31, 2000. Total assets increased to $4.0 billion at December
31, 1999, a 31% increase from $3.1 billion at December 31, 1998. Assets held
in separate accounts were $693.4 million, or 17%, of total assets in 1999 and
$722.3 million, or 23%, in 1998. As detailed in note 2A to the consolidated
financial statements, these assets are principally managed assets attributable
to participants in our IPC Programs. Total assets also increased due to the
increase in reinsurance receivables from $1,079.6 million in 1998 to $1,729.9
million in 1999. This increase, which is largely offset by corresponding
increases in the reserve for losses and loss expenses and accounts payable,
was due to the greater amount of reinsurance utilized in connection with our
Program Business segment.

Inflation

  We do not believe our operations have been materially affected by inflation.
The potential adverse impacts of inflation include: (1) a decline in the
market value of our fixed maturity investment portfolio; (2) an increase in
the ultimate cost of settling claims which remain unresolved for a significant
period of time; and (3) an increase in our operating expenses. However, we
generally hold our fixed maturity investments to maturity and currently
believe that an acceptable amount is included in the yield to compensate us
for the risk of inflation. In addition, any increase from inflation in the
ultimate cost of settling unpaid claims will be borne by our clients and
offset by investment income earned for the benefit of the client during the
period that the claim is outstanding. Finally, the increase in operating
expenses resulting from inflation should generally be matched by similar
inflationary increases in the client's premium and our fee income, which
includes a fee based upon a percentage of the client's premium.

Market Sensitive Instruments

  Market risk generally represents the risk of loss that may result from
potential change in the value of a financial instrument due to a variety of
market conditions. Our exposure to market risk is generally limited to
potential losses arising from changes in the level or volatility of interest
rates on market values of investment holdings and on a bridging loan. Our
exposure to movements in exchange rates and equity prices is limited. We do
not hold or issue significant derivative financial instruments for trading or
speculative purposes.

 Interest Rate Risk

  Interest rate risk results from our holdings in interest-rate-sensitive
instruments. We are exposed to potential losses arising from changes in the
level or volatility of interest rates on fixed rate instruments held. We are
also exposed to credit spread risk resulting from possible changes in the
issuer's credit rating. To manage our exposure to interest rate risk, we
attempt to select investments with characteristics that match the
characteristics of the related insurance and contract holder liabilities.
Additionally, we generally only invest in higher-grade interest bearing
instruments.

  We are also exposed to interest rate risk on our bridge loan facility, which
bears interest at LIBOR plus 0.75%. During 1999, $110 million of this facility
was contributed to the U.S. insurance companies and has been invested in a
variable rate debt instrument with matching terms and maturity to cover the
interest cost of the bridge loan facility. As of March 31, 2000, $217 million
was outstanding under the bridge loan facility.

 Foreign Exchange Risk

  When we invest in non-U.S. dollar denominated financial instruments, we are
subject to exposure from exchange rate movements. This risk arises from the
possibility that changes in foreign exchange rates will impact adversely upon
the value of financial instruments. Due to our limited holdings of non-U.S.
dollar denominated investments, management does not believe that we are
exposed to a material risk from exchange rate movements.

 Equity Price Risk

  Equity price risk arises from fluctuations in the value of securities held.
Changes in the level or volatility of equity prices affect the value of equity
securities held by us. Management does not believe that we are exposed to a
material risk from changes in equity prices due to our limited investment in
equity securities.

  The tables below provide information about our available for-sale
investments that are sensitive to changes in interest rates at December 31,
1999 and 1998, respectively. The tables present expected cash flows and
related weighted-average interest rates by expected maturity dates. Separate
account assets and liabilities are not

included in this analysis as gains and losses related to these accounts
generally accrue to the program holders. There were no material quantitative
changes in market risk exposure between the current and preceding fiscal year
with respect to available for-sale investments.

Impact of Year 2000

  We have not experienced any significant year 2000 issues to date. All
systems identified for replacement before the year 2000 were replaced. Since
we regularly update our hardware and software, the pure additional cost of
year 2000 compliance was not material.

  We have taken steps that we believe are reasonably designed to obtain
assurances that our critical customers, reinsurance intermediaries, managing
general agents, suppliers and others have addressed their year 2000 compliance
efforts. Although the change in date to year 2000 has occurred, it is not yet
possible to conclude that all aspects of the year 2000 issue that may affect
us relating to other third party providers have been fully resolved. The
inability of our third party providers to properly address the year 2000 issue
could have an adverse material impact on our financial position or results of
operations. Management will continue to monitor the status of and its exposure
to this issue, however, we have not experienced any significant year 2000
issues to date. Contingency plans are still in place should critical
customers, reinsurance intermediaries, managing general agents, suppliers and
others fail to resolve their own year 2000 issues. To date, we have not been
notified of any year 2000 related claims.

Acquisitions

  On March 1, 1999, we acquired Captive Resources, Inc., also referred to in
this prospectus supplement as CRI, a provider of services to member owned
group captive insurance companies. CRI has long-term contracts with more than
20 well established captives.

Recent Accounting Pronouncements

  In October 1998, the Accounting Standards Executive Committee issued
Statement of Position 98-7, "Deposit Accounting: Accounting for Insurance and
Reinsurance Contracts That Do Not Transfer Insurance Risk." This statement
provides guidance on how to account for insurance and reinsurance contracts
that do not transfer insurance risk under deposit accounting. The statement is
effective for fiscal years beginning after June 15, 1999 with early adoption
encouraged. We do not expect this statement to have a material impact on our
financial position or results of operations.

                                     S-17
<PAGE>

  In June 1998, the Financial Accounting Standards Board issued Statement 133,
"Accounting for Derivative Instruments and Hedging Activities," which was
amended by Statement 137 in June 1999. This statement requires recording all
derivative instruments as assets or liabilities, measured at fair value. The
statement is effective for fiscal years beginning after June 15, 2000. We do
not expect this statement to have a material impact on our financial position
or results of operations.

                                  OUR COMPANY

  MRM is a Bermuda company incorporated in 1977. Mutual Group is a Delaware-
based holding company that was incorporated in 1979. Our principal business is
the provision of risk management services to clients seeking an alternative to
traditional commercial insurance for risk exposures. Risk management involves
a process of analyzing loss exposures and developing risk financing methods to
reduce exposure to loss and to control associated costs. The use of loss
financing methods in place of traditional insurance has become known as the
alternative market and involves clients participating in a significant amount
of their loss exposure and transferring only the unpredictable excess risk to
insurers. The benefits of alternative market techniques typically include
lower and more stable costs, greater control over the client's risk management
program and an increase in the emphasis within the client's organization on
loss prevention and loss control. In addition, we provide financial services
to offshore mutual funds and other companies.

Income from fees is derived from four distinct business segments:

  Program Business--The largest of our business segments. In this segment, we
  replace traditional insurers as the conduit between producers of specialty
  books of business and reinsurers wishing to write that business. We provide
  a range of services for a fee and the underwriting profit is shared between
  the producer and the reinsurers. The Program Business accounted for 53% of
  fee income for the year ended December 31, 1999 and 55% of fee income for
  the quarter ended March 31, 2000.

  Corporate Risk Management--Our original business segment. Corporate Risk
  Management involves providing services to businesses and associations
  seeking to insure a portion of their risk in a loss sensitive alternative
  market structure. We earn our fees by designing and implementing risk
  financing and loss control programs for medium-sized and large companies
  that seek to insure a portion of their insurable risk. Corporate Risk
  Management accounted for 28% of fee income for the year ended December 31,
  1999 and 23% of fee income for the quarter ended March 31, 2000.

  Specialty Brokerage--Our Specialty Brokerage segment specializes in placing
  reinsurance for captive insurance companies, placing coverage with excess
  liability and corporate officers' and directors' liability carriers and
  placing reinsurance in connection with our Program and Corporate Risk
  Management businesses. Specialty Brokerage accounted for 8% of fee income
  for the year ended December 31, 1999 and 8% of fee income for the quarter
  ended March 31, 2000.

  Financial Services--Our Financial Services segment started in 1996 with the
  acquisition of The Hemisphere Group Limited. The Financial Services segment
  provides administrative services to offshore mutual funds and other
  companies and offers a proprietary family of mutual funds as well as asset
  accumulation life insurance products for the high net worth market.
  Financial Services accounted for 11% of fee income for the year ended
  December 31, 1999 and 14% of fee income for the quarter ended March 31,
  2000.

Insurance Services

  Our principal source of profits is fees received for the various insurance
and other services provided to clients in connection with our programs. The
structure of our programs places most of the underwriting risk with our
clients or reinsurers. For regulatory and other reasons, however, we are
required to assume a limited amount of risk. We seek to limit this risk to the
minimum level feasible. This approach to risk distinguishes us from typical
property/casualty companies, which assume significant levels of underwriting
risk as part of their business. We do not seek to earn income from
underwriting risk but rather from fees for services provided. We market our
services exclusively to retail insurance brokers and consultants representing
clients. The services offered to clients in connection with our products
typically include the following:

  . design and implementation of a risk financing program;

  . issuance of an insurance policy by one of our wholly-owned, licensed
    insurance companies, Legion Insurance Company, also referred to in this
    prospectus supplement as Legion Insurance, Legion Indemnity Ltd., also
    referred to as Legion Indemnity, and Villanova Insurance Company, also
    referred to in this prospectus supplement as Villanova. These companies
    are collectively referred to as the Legion Companies. The Legion
    Companies have a group rating of "A ," excellent, from A.M. Best Company;

                                     S-19
<PAGE>

  . use of our Insurance Profit Center Program, also known as the IPC
    Program, as the vehicle within which to fund a chosen portion of the
    client's risk or, alternatively, the management by us of the client's
    captive insurance company;

  . brokering to unaffiliated reinsurers the excess risk which the client
    chooses not to fund and, in some cases, arranging for insurers, other
    than Legion Insurance, to issue the original insurance policy; and

  . coordinating the purchase, on behalf of the client, of loss prevention,
    loss control and claims administration services from unaffiliated
    providers.

  Our major product is the IPC Program. This program allows the client to
retain a significant portion of its own loss exposure without the
administrative costs and capital commitment necessary to establish and operate
its own captive insurance company. The actual amount of underwriting profit
and investment income produced by the client's IPC Program is returned to the
client creating a direct incentive for it to engage in loss prevention and
loss control in order to reduce the overall cost of financing its loss
exposures.

  The largest segment of our insurance business is our Program Business, in
which third-parties other than the insured, typically the broker and
reinsurers, finance a portion of the insured's risk and participate in any
underwriting profit or loss, in other words, agency IPC programs.

Lines of Business

  Our programs can be utilized by clients for many lines of insurance. In
1999, approximately 53% of our fee income was derived from workers'
compensation insurance. During the 1980's and through 1993, workers'
compensation presented many employers with substantial problems due to cost
increases and the limited availability of commercial coverage in certain
states. Workers' compensation costs accelerated rapidly because of: (1) the
general level of medical cost inflation, as medical costs generally amount to
40% or more of all workers' compensation costs; (2) an increase in the number
of workers' compensation claims which resulted in litigation; (3) a broadening
of injuries which are considered to be work-related; and (4) an increase in
state mandated benefit levels. Since 1993, workers' compensation reforms have
been occurring in a number of states, most notably in California, which have
addressed many of these issues. A number of markets have seen a significant
decline in premium rates due to new capacity entering the market subsequent to
these reforms. These lower premium rates have reduced the fees we earn on our
programs as fees are based on premiums. Notwithstanding the changes in the
market, workers' compensation continues to be suitable for the alternative
market because many states set rates or enforce minimum rate laws which
prohibit the commercial insurance market from offering premium discounts to
insureds with favorable loss experience. This causes these clients to seek an
alternative method of funding their workers' compensation exposure, which
rewards their status as a preferred risk. In addition, workers' compensation
involves relatively frequent, predictable levels of loss, which are the type
favored by clients for alternative market insurance programs.

  In addition to workers' compensation, our programs have been utilized for
other casualty insurance lines such as medical malpractice, general liability,
commercial auto liability and auto physical damage.

  At March 31, 2000, we had a total of 1,177 employees.

Marketing--Commonwealth Risk Services, L.P.

  Our wholly owned subsidiary, Commonwealth Risk Services, L.P., also referred
to in this prospectus supplement as CRS, markets our services in the United
States, Canada and Europe to insurance brokers and consultants representing
clients. CRS also designs risk financing programs for potential clients in
conjunction with their insurance brokers and consultants. Through offices in
Philadelphia, California and London, CRS markets these services using direct
mail, advertising, seminars and trade and industry conventions.

  CRS seeks to become actively involved with the insurance broker in the
presentation of our services to potential clients and maintains a direct
relationship with the client after the sale. CRS assists brokers in the design

                                     S-20
<PAGE>

and implementation of risk financing programs, although the extent of this
involvement depends on the size, experience and resources of the particular
broker. Members of the CRS staff frequently provide supporting promotional
materials and assist in the preparation of financial analyses comparing the
net present value, after-tax cost of an IPC Program with alternative
approaches. Representatives of CRS seek to be present at meetings with
potential clients to explain how the IPC Program works, including how
reinsurance is handled, how funds are invested and how underwriting profits
and investment income are returned.

The Insurance Profit Center Program and Program Business

  In 1980, we developed a program which provides clients with a facility for
managing their insurance exposures. This type of structure is frequently
referred to as a "rent-a-captive," although the facility has many significant
differences from a captive insurance company. The facility was designed to
provide certain of the benefits available through captive insurance companies
without the administrative cost and capital commitment necessary to establish
and operate a captive insurance company. Since the IPC Program involves a
retention of risk by the client, it encourages the implementation of risk
management and risk reduction programs to lower the losses incurred.

  The IPC Program is appropriate for corporations and associations which
generate $.75 million or more in annual premiums. Typically, clients which use
an IPC Program are profitable and have adequate working capital but generate
insufficient premium to consider, or are otherwise unsuitable for, a wholly-
owned captive. During 1999, we increased the number of agency IPC Programs in
which an insurance agent or broker, rather than the insured, becomes the
preferred shareholder and participates in the profit or loss on the program.
These types of programs are referred to as "Program Business" and are
discussed below.

  Return on the IPC program is a function of the loss experience of the
insured. The principal benefits of the IPC Program to the client are:

  . a reduction of the net present value, after-tax cost of financing the
    client's risks;

  . a lower commitment of funds than would be necessary to capitalize and
    maintain a captive insurance company;

  . access to commercial reinsurance markets for the client's excess risk;
    and

  . program structure that is customized, flexible and relatively easily
    implemented.

  We operate the IPC Program from offices in Bermuda. The Bermuda office is
involved in designing, negotiating and administering IPC Programs and reviews
each prospective client, negotiates the shareholder's agreement with the
client and the reinsurance agreement with Legion Insurance or another policy-
issuing company. One of our foreign insurance companies, also referred to as
one of the IPC Companies, receives and invests premiums, administers policy
claims, establishes reserves, provides quarterly financial reports to clients
and, ultimately, returns the underwriting profit and investment income to the
client as preferred share dividends.

  The funds of each IPC Program are invested by our subsidiary, Mutual Finance
Ltd. The funds are invested using the services of professional investment
advisors.

  Neither Legion Insurance nor the IPC Companies underwrite risk in the
traditional sense. Rather, their function is to ensure that substantially all
of the underwriting risk of the client is either retained by the client in the
IPC Program or its captive insurance company, as the case may be, or
transferred to unaffiliated reinsurers. In the event that the IPC Company
sustains an underwriting loss on a program which exceeds that program's
investment income, the IPC Company recovers this loss from the client. Since
the client has generally collateralized the IPC Company for at least the
difference between the funds available in that client's IPC Program and the
level of currently expected losses by cash or a letter of credit, the IPC
Company should not be affected by the bankruptcy of a client. In the event,
however, that the IPC Company is unable to recover the full amount of its loss
from the cash collateral or the letter of credit, the IPC Company would seek
to recover from the client pursuant to the indemnity provisions of the
shareholder's agreement. As of December 31, 1999, we maintained a provision of
$10.0 million against losses which may occur on programs where we may be
forced to rely solely on the client's indemnity.

                                     S-21
<PAGE>

  In addition to programs for corporate clients, we also offer an association
IPC Program, which allows smaller insureds to collectively take advantage of
the financial benefits available to larger corporate insureds individually.

The Legion Companies

  Legion Insurance is domiciled in Pennsylvania and is admitted to write
primary insurance, often called being admitted or writing insurance on an
admitted basis, in all 50 states of the United States, the District of
Columbia and Puerto Rico. Legion Indemnity is domiciled in Illinois, is an
admitted insurer in Illinois and is an authorized surplus lines insurer in 42
states, the District of Columbia, Guam and the Virgin Islands. An authorized
surplus lines insurer writes specialty property and liability coverage when
the specific specialty coverage is unavailable from admitted insurers.
Villanova is domiciled in Pennsylvania and is admitted to write primary
insurance in 43 states.

  In our Corporate Risk Management business segment, one of the Legion
Companies issues an insurance policy to the client, which either fulfills a
legal requirement that the client have a policy from a licensed insurer or
satisfies a business need the client may have for an admitted policy. The
client and the Legion Company determine the level of exposure the client
wishes to retain and the Legion Company transfers the specific excess risk and
the aggregate excess risk beyond that retention to unaffiliated reinsurers.
The Legion Company then reinsures the client's chosen retention to one of the
IPC Companies or to the client's captive insurance company. In certain cases
the Legion Company may issue a large deductible type policy through which the
client pays claims up to its chosen retention directly. Payments within the
deductible are covered by a deductible reimbursement policy issued by one of
the IPC Companies. In either type of policy, the Legion Company retains only a
relatively small portion of the risk on each program for its own account.

  In our Program Business, the Legion Company replaces traditional insurers as
the conduit between producers of specialty books of business and reinsurers
wishing to write that business. In this line of business, the reinsurer
replaces the insured as the risk-bearing entity. As with the Corporate Risk
Management line of business, the Legion Company negotiates the reinsurance and
performs certain administrative services in connection with the program.
Program Business differs from the Corporate Risk Management line of business
in that policy underwriting, issuance and premium collection are usually
provided by the general agent, rather than the Legion Company. The Legion
Company analyzes each program prior to inception, arranges for quota share or
specific and aggregate excess reinsurance coverage through its reinsurance
treaties, collects the premium from the client, prepares accounting cessions
for the reinsurers, audits the final premium, supervises the independent
claims adjuster, collects claim reimbursements from reinsurers and performs
certain other related services for each account.

  For the Corporate Risk Management business, the Legion Companies have
established a reinsurance treaty with an unaffiliated reinsurer to transfer
the specific and aggregate excess risk above the client's retention. The
client's retention is negotiated separately for each program and reflects the
amount of risk the client wishes to retain for its program on both a specific
and aggregate basis. For the Program Business, each Legion Company purchases a
separate reinsurance treaty, both on a quota share and a specific and
aggregate excess of loss basis.

  The Legion Companies currently place substantially all reinsurance with
unaffiliated commercial reinsurers whose ratings from A.M. Best Company are A-
or higher. At December 31, 1999, the largest reinsurance recoverables from
unaffiliated commercial reinsurers were $172.6 million from Transatlantic
Reinsurance Company, a participant on several layers of specific and aggregate
reinsurance with respect to various of our Program and Corporate Risk
Management business and substantially all of our American Psychiatric
Association program, $161.3 million from First Excess and Reinsurance Corp.
and $145.4 million from American Re-insurance Company, which are both
reinsurers on several current treaties. Transatlantic is rated "A++," First
Excess, now GE Reinsurance Corporation and part of the Employers Re U.S.
Group, is rated "A++" and American Re-insurance is rated "A++" by A.M. Best
Company.

                                     S-22
<PAGE>

  Through its reinsurance arrangements, each Legion Company places significant
amounts of reinsurance with a variety of unaffiliated reinsurance companies.
In order to maintain an acceptable level of net written premium for regulatory
purposes, each Legion Company seeks to develop a level of net written premium
which will not involve a significant degree of underwriting risk. In most
Legion programs, the Legion Company retains liability for a specified amount
of losses equal to at least 10% of the gross written premium. The level of
losses retained by the Legion Company are set at a level so that no
significant underwriting profit or loss should occur.

  In order to take regulatory credit for reinsurance ceded to one of the IPC
Companies or to a captive insurance company, the Legion Company must receive a
letter of credit for the amount of the insurance reserves ceded since the
companies to which the reinsurance is ceded are not licensed reinsurers in any
state of the United States. The letter of credit must be issued or confirmed
by a bank which is a member of the U.S. Federal Reserve System. At December
31, 1999, the Legion Companies had $371 million of letters of credit, of which
$257 million was supplied by the IPC Companies. Legion Insurance, Legion
Indemnity and Villanova are also subject to other regulation by the insurance
departments of Pennsylvania, Illinois and other states where they are
licensed.

  As of December 31, 1999, the Legion Companies had 355 accounts and had
statutory capital of $349.9 million. They wrote gross statutory premiums of
$1.2 billion during 1999.

Specialty Brokerage

  In 1991, we acquired a 51% interest in a newly-formed London reinsurance
brokerage firm, MRM Hancock Limited. MRM Hancock specializes in the placement
of reinsurance for captive insurance companies in the London market, including
Lloyds of London. In 1996, we acquired the remaining 49% of MRM Hancock from
the management of MRM Hancock and General International Ltd., a Bermuda
insurance subsidiary of General Motors Corporation. MRM Hancock is now a
wholly owned subsidiary. In July 1992, we acquired Park International Limited,
a Bermuda broker specializing in placing coverage with Bermuda-based excess
liability and corporate officers' and directors' liability carriers. In 1998,
we acquired H&H Reinsurance Brokers, Ltd., a Bermuda-based specialty
reinsurance broker that was part of the IAS Group, a group of companies that
was acquired by MRM in 1998. During 1999, all of our brokerage business was
combined into one unit to better coordinate the specialty brokerage activities
and to improve customer service.

Financial Services

  In July 1996, we acquired The Hemisphere Group Limited, a Bermuda financial
services company. Hemisphere has been in business since 1980 and has three
active subsidiary operations in Bermuda providing company management,
corporate secretarial, fund administration and trust management services. With
a total staff of 158, Hemisphere had approximately 279 mutual fund clients as
of December 31, 1999. In addition, Hemisphere administers investment holding
companies, trading companies and trusts. Hemisphere has formed a network of
professional relationships in the major financial centers of the world, and
this network is the source for significant ongoing referrals of business.
During 1997, Hemisphere expanded its trust operations by the acquisition of
Hugo Trust Company based in Jersey in the Channel Islands. Hemisphere Trust
(Jersey) Limited, which is comprised of Hugo Trust Company and Augres Trust
Company, provides a base to develop European-based trust business and had
revenues of $2.8 million in 1999.

  In January 1997, we incorporated MRM Life Ltd. in Bermuda to provide life
insurance and related products, including annuities and variable annuities. We
began marketing these products in the fourth quarter of 1997.

  In 1998, Hemisphere expanded its operations to Dublin, Ireland and Boston,
Massachusetts in order to service the European offshore and US hedge fund
industries, respectively.

Competition

  Our insurance services compete with self-insurance plans, captive insurance
companies managed by others and a variety of risk financing insurance
policies. We believe that the IPC Program is the largest independent
alternative market facility that is not affiliated with either a major retail
insurance broker or a major insurance company. We face significant competition
in marketing the IPC Program from other risk management programs offered by
U.S. insurance companies, from captive insurance companies for large insureds
and from rent-a-captives organized by large insurance companies and brokers.

  The primary basis for competition among these alternative risk management
vehicles varies with the financial and insurance needs and resources of each
potential insurance buyer. The principal factors that are considered include
an analysis of the net present-value, after-tax cost of financing the client's
expected level of losses, the amount of premium and collateral required, the
attachment point of excess coverage provided in the event losses exceed
expected levels as well as cash flow and tax planning considerations and the
expected quality and consistency of the services to be provided. We believe
that for insureds with financial characteristics and loss experience lending
themselves to an IPC Program, the IPC Companies compete effectively with other
risk financing alternatives.

  In a soft insurance market, characterized by excess capital and competitive
pricing, it is generally easier for us to structure programs because of the
availability and pricing of reinsurance but more difficult to attract
potential participants and sell programs because of competition. In a hard
market, such as that experienced during 1985-1987, it is more difficult to
structure programs due to the high price and unavailability of reinsurance,
but we experience less competition in attracting clients and selling programs.

Regulatory Considerations

  The Bermuda-based IPC Companies, Mutual Indemnity Ltd., Mutual Indemnity
(Bermuda) Ltd. and Mutual Indemnity (US) Ltd., are subject to regulation under
the Bermuda Companies Act of 1981 and as insurers under the Bermuda Insurance
Act of 1978, as amended by the Insurance Amendment Act of 1995 and the
regulations promulgated thereunder. They are required, among other things, to
meet and maintain standards of solvency, to file periodic reports in
accordance with Bermuda statutory accounting rules, to produce annual audited
financial statements and to maintain a minimum level of statutory capital and
surplus. In general, the regulation of insurers in Bermuda relies heavily upon
the auditors, directors and managers of the Bermuda insurer, each of which
must certify that the insurer meets the solvency and capital requirements of
the Bermuda Insurance Act of 1978. Mutual Indemnity (Barbados) Ltd. and Mutual
Indemnity (Dublin) Ltd. are subject to similar regulation in Barbados and
Ireland, respectively.

  The Legion Companies are subject to regulation and supervision by the
insurance regulatory authorities of the various states of the United States in
which they conduct business. This regulation is intended primarily for the
benefit of policyholders. Legion Insurance is admitted in 50 states, the
District of Columbia and Puerto Rico, and is subject to regulation in each
jurisdiction. Legion Indemnity is admitted in Illinois and is authorized as a
surplus lines insurer in 42 states, the District of Columbia, Guam and the
Virgin Islands. Legion Indemnity is regulated in Illinois but is generally not
subject to regulation in those states where it acts as a surplus lines
insurer. Villanova is admitted in 43 states and is subject to regulation in
each jurisdiction. State insurance departments have broad regulatory,
supervisory and administrative powers. These powers relate primarily to the
standards of solvency which must be met and maintained, the licensing of
insurers and their agents, the approval of rates and forms and policies used,
the nature of, and limitations on, insurers' investments, the form and content
of periodic and other reports required to be filed and the establishment of
reserves required to be maintained for unearned premiums, losses and loss
expenses or other purposes.

  The Legion Companies are also subject to state laws regulating insurance
holding companies. Under these laws, state insurance departments may examine
the Legion Companies at any time, require disclosure of material transactions
by each of the holding companies and require prior approval of certain
"extraordinary" transactions,

                                     S-24
<PAGE>

such as dividends from the insurance subsidiary to the holding company and
purchases of certain amounts of the insurance subsidiary's capital stock.
These laws also generally require approval of changes of control, which are
usually triggered by the direct or indirect acquisition of 10% or more of the
insurer.

  Most states require all admitted insurance companies to participate in their
respective guaranty funds, which cover claims against insolvent insurers.
Solvent insurers licensed in these states are required to cover the losses
paid on behalf of insolvent insurers by the guaranty funds and are generally
subject to annual assessments in the state by its guaranty fund to cover these
losses. Some states also require licensed insurance companies to participate
in assigned risk plans which provide coverage for workers' compensation,
automobile insurance and other lines for insureds which, for various reasons,
cannot otherwise obtain insurance in the open market. This participation may
take the form of reinsuring a portion of a pool of policies or the direct
issuance of policies to insureds. Generally, the Legion Companies participate
as pool reinsurers or assign to other companies the direct policy issuance
obligations. The calculation of an insurer's participation in these plans is
usually based on the amount of premium for that type of coverage that was
written by the insurer on a voluntary basis in a prior year. Assigned risk
pools tend to produce losses which result in assessments to insurers writing
the same lines on a voluntary basis. The Legion Companies also pay a fee to
carriers assuming their direct policy issuance obligations. For each program a
Legion Company writes, it estimates the amount of assigned risk and guaranty
fund assessments that it will incur as a result of having written that
program. If that estimate proves to be inadequate, the Legion Company is
entitled under its reinsurance agreements with the IPC Companies to recover
from the reinsurer the amount of any assessments in excess of the estimate.
The IPC Companies are then entitled under the terms of each shareholder's
agreement to recover this excess from the client. However, the IPC Companies
are generally only able to collateralize this obligation up to the amount of
the estimated assessments.

  The NAIC has established the Insurance Regulatory Information System, also
referred to in this prospectus supplement as IRIS, to assist state insurance
departments in their regulation and oversight of insurance companies domiciled
or operating in their respective states. IRIS has established a set of twelve
financial ratios with specified "unusual values" for each ratio. Companies
reporting four or more unusual values on the IRIS ratios may expect inquiries
from individual state insurance departments concerning specific aspects of the
insurer's financial position. As of December 31, 1999, Legion Insurance,
Villanova and Legion Indemnity had six, four and three unusual values,
respectively. Four of Legion Insurance's ratios, change in net writings,
surplus aid to surplus, agent's balance to surplus and estimated current
reserve deficiency to surplus, are directly related to premium growth. Change
in surplus was unusual due to the $143.0 million of additional capital
contributed during 1999. The final ratio, liabilities to liquid assets, was
unusual due to the receipt of $35 million in premium prior to the receipt of
policy level detail to record the written premium. This inflates the ratio as
it represents funds awaiting application to actual policies.

  Villanova had four unusual values related to premium growth, change in net
writings and estimated current reserve deficiency to surplus. It also had an
unusual value for low investment yield. The low value for investment yield is
the result of actual investments made late in the year while the ratio is
calculated assuming investments were made evenly throughout the year. The last
unusual value for Villanova was a decrease in surplus. This was the result of
the dividends to its parent and the sharing of receivables write-offs under
our pooling arrangement.

  Legion Indemnity had three unusual values, all premium growth related. They
were change in net writings, surplus aid to surplus and agent's balance to
surplus.

  The NAIC has also adopted the Risk Based Capital for Insurers Model Act. The
Risk Based Capital Model Act sets forth a risk-based capital formula for
property and casualty insurers. The formula measures minimum capital and
surplus needs based on the risk characteristics of a company's products and
investment portfolio. The formula is part of each company's annual financial
statement filings and is to be used as a tool to identify weakly capitalized
companies. In those states having enacted the Risk Based Capital Model Act,
companies having capital and surplus greater than the minimum required by the
formula but less than a specified multiple of the minimum may be subject to
additional regulatory scrutiny from domiciliary state insurance departments.
To date, nearly all states have adopted the Risk Based Capital Model Act. At
December 31, 1999, the Legion

                                     S-25
<PAGE>

Companies combined risk-based capital was $347.4 million. Under the risk-based
capital tests, the threshold that constitutes the authorized control level
which authorizes the commissioner to take whatever regulatory action
considered necessary to protect the best interest of the policyholders and
creditors of the Legion Companies was $121 million. Therefore, the Legion
Companies capital exceeds the requirements of the Risk Based Capital Model
Act.

  In reaction to increasing rates for and decreasing availability of workers'
compensation insurance starting in the early 1990's, many states began to
enact reforms designed to reduce the cost of workers' compensation insurance,
principally through a reduction in benefits or an increase in efficiencies in
the system. In California, a reform package was enacted in 1993 providing for,
in part, a reduction of premium rates, an increase in the standard necessary
to prove "stress-related" work injuries, group-self insurance for employers
and the repeal of the minimum rate law effective January 1, 1995. In Florida,
the assigned risk plan was abolished and replaced by a joint underwriting
authority. Other states have enacted or are considering similar reforms.
Workers' compensation reform, together with the effects of competition and
other factors, has led to reduced premiums in many states. This has reduced
the appeal of alternative market products such as those offered by us. This is
apparent in California where workers' compensation rates have declined by more
than 50% since mid-1993 while benefit levels have increased. This will
inevitably lead to significant losses for those traditional carriers who are
writing this business. A number of these carriers have recently filed for
significant rate increases.

  The Legion Companies are permitted to pay dividends only from statutory-
earned surplus. Subject to this limitation, the maximum amount of dividends
that each Legion Company is able to pay in any twelve-month period will be the
greater of statutory net income in the preceding year or 10% of its statutory
surplus. Based on 1999 results, the maximum dividend the Legion Companies
would collectively be permitted to pay in 2000 is $35.0 million.

Losses and Loss Reserves

  We establish reserves for losses and loss adjustment expenses related to
claims that have been reported on the basis of the evaluations of independent
claims adjusters under the supervision of the claims staff of each Legion
Company. In addition, reserves are established for losses that have occurred
but have not yet been reported and for adverse development of reserves on
reported losses by us on a quarterly basis. The estimate of claims arising for
accidents that have not yet been reported is based upon our and the insurance
industry's experience together with statistical information with respect to
the probable number and nature of these claims.

  Gross loss reserves of $136.0 million and $121.0 million at December 31,
1999 and 1998, respectively, have been discounted by $39.5 million and $36.2
million, respectively, assuming interest rates of 6% for medical malpractice
reserves and 4% for excess workers' compensation reserves based on the
recommended rate under Pennsylvania law. These reserves are also discounted in
our regulatory filings. In 1993, we adopted SFAS 113 and reclassified
substantially all of our net retained medical malpractice reserves as claims
deposit liabilities. On a net basis, therefore, the only discounted reserves
are those relating to our share of the excess reinsurance coverage provided in
connection with each program. This discounting reduced net loss reserves on
our consolidated balance sheets by $3.8 million and $4.7 million at December
31, 1999 and 1998, respectively.

  Prior to 1995, loss development had been generally favorable. The adverse
development in recent years has principally been a result of losses on
terminated programs.

  The following table presents the development of our ongoing net reserves for
1989 through 1999. The top line of the table shows the estimated reserve for
unpaid losses and loss adjustment expenses recorded at the balance sheet date
for each of the indicated years. This amount represents the estimated amount
of losses and loss adjustment expenses for claims that are unpaid at the
balance sheet date, including losses that have been incurred but not yet
reported to us. The table also shows the re-estimated amount of the previously
recorded reserve based on experience as of the end of each succeeding year.
The estimate changes as more information becomes known about the frequency and
severity of claims for individual years. The "cumulative redundancy
(deficiency)" represents the aggregate change in the estimates over all prior
years. It should be noted that the following table presents a "run off" of
balance sheet reserves, rather than accident or policy year loss development.
Therefore, each amount in the table includes the effects of changes in
reserves for all prior years.

                        DESCRIPTION OF THE SENIOR NOTES

  The following description of the particular terms of the senior notes
offered hereby supplements, and to the extent inconsistent therewith replaces,
the description of the general terms and provisions of senior notes set forth
in the attached prospectus.

General

  The senior notes will be issued as a series of debt securities under the
senior indenture, dated as of June   , 2000, between MRM, Mutual Group and The
Chase Manhattan Bank, as trustee. For a description of the rights attaching to
different series of senior notes under the senior indenture, see "Description
of the Senior Notes and the MRM Senior Note Guarantees" in the attached
prospectus.

  The senior notes will be issued as unsecured obligations of Mutual Group,
will be limited to an aggregate principal amount of $150,000,000, will be
issued only in book-entry form through the facilities of The Depository Trust
Company, referred to in this prospectus supplement as DTC, and will be in
denominations of $1,000 and integral multiples thereof. The senior notes will
mature on         . Transfers or exchanges of beneficial interests in the
senior notes in book-entry form may be effected only through a participating
member of DTC. See "Global Securities" below. The senior notes will bear
interest from        , 2000, payable in arrears on each         and
  , commencing              , 2000 at the rate set forth on the cover page of
this prospectus supplement, to the persons in whose names the senior notes are
registered on the preceding           and         , respectively.

Guarantee

  MRM will fully and unconditionally guarantee all obligations with respect to
the senior notes.

Optional Redemption

  Mutual Group may on any one or more occasions redeem all or any part of the
senior notes at a redemption price equal to the greater of:

  . 100% of the principal amount of the senior notes to be redeemed; and

  . the sum of the present values of the remaining scheduled payments of
    principal and interest on those senior notes from and after the date of
    redemption discounted to the redemption date on a semi-annual basis,
    assuming a 360-day year consisting of twelve 30-day months, at the
    Treasury Rate plus 25 basis points;

plus, in each case, accrued and unpaid interest to the date of redemption.

  "Treasury Rate" means, with respect to any redemption date, the rate per
annum equal to the semi-annual equivalent yield to maturity of the Comparable
Treasury Issue, assuming a price for the Comparable Treasury Issue, expressed
as a percentage of its principal amount, equal to the Comparable Treasury
Price for such redemption date.

  "Comparable Treasury Issue" means the United States Treasury security
selected by an Independent Investment Banker as having a maturity comparable
to the remaining term of the senior notes to be redeemed that would be
utilized, at the time of selection and in accordance with customary financial
practice, in pricing new issues of corporate debt securities of comparable
maturity to the remaining term of the senior notes.

  "Independent Investment Banker" means one of the Reference Treasury Dealers
appointed by Mutual Group.

  "Reference Treasury Dealer" means each of Prudential Securities
Incorporated, Banc of America Securities LLC, Salomon Smith Barney Inc. and
PaineWebber Incorporated and their respective successors; provided, that if
any of the foregoing shall cease to be a primary U.S. Government securities
dealer in New York City, Mutual Group shall substitute another primary
treasury dealer.

                                     S-30
<PAGE>


  "Comparable Treasury Price" means, with respect to any redemption date,


  . the average of the Reference Treasury Dealer Quotations for such
    redemption date, after excluding the highest and lowest of such Reference
    Treasury Dealer Quotations, or

  . if the trustee is unable to obtain at least three such Reference Treasury
    Dealer Quotations, the average of all Reference Treasury Dealer
    Quotations obtained.

  "Reference Treasury Dealer Quotations" means, with respect to each Reference
Treasury Dealer and any redemption date, the average, as determined by the
trustee, of the bid and asked prices for the Comparable Treasury Issue,
expressed in each case as a percentage of its principal amount, quoted in
writing to the trustee by such Reference Treasury Dealer at 5:00 p.m., New
York City time, on the third business day preceding such redemption date.

  Notice of any redemption will be mailed at least 30 days but not more than
60 days before the redemption date to each holder of the senior notes to be
redeemed.

  Unless Mutual Group defaults in payment of the redemption price, on or after
the redemption date, interest will cease to accrue on the senior notes or
portions of the senior notes called for redemption.

  The senior notes will not be entitled to any sinking fund.

Global Securities

  The senior notes will be represented by one or more global securities
registered in the name of the nominee of DTC, and will be available for
purchase in denominations of $1,000 and any integral multiple of $1,000. Each
global security will be deposited with DTC, its nominee or custodian and will
bear a legend regarding the restrictions on exchanges and registration of
transfer of the senior notes referred to below and any other matters as may be
provided for pursuant to the senior indenture.

  Ownership of beneficial interests in a global security will be limited to
institutions that have accounts with DTC or its nominee, often called
participants, or persons that may hold beneficial interests through
participants. In addition, ownership of beneficial interests by participants
in a global security will be evidenced only by, and the transfer of that
ownership interest will be effected only through, records maintained by DTC or
its nominee. Ownership of beneficial interests in the global security by
persons that hold through participants will be evidenced only by, and the
transfer of that ownership interest within the participant will be effected
only through, records maintained by the participant. Some insurance companies
and other institutions are required by law to hold their investment securities
in definitive form, so an investor may not be able to sell its senior notes to
those entities.

  Payments on the senior notes represented by any global security will be made
to DTC's nominee as the registered owner and holder of the global security.
None of MRM, Mutual Group, the trustee or any agent of MRM, Mutual Group or
the trustee will have any responsibility or liability for any aspect of DTC's
or its nominee's records or any participant's records relating to or payments
made on account of the beneficial ownership interests in a global security or
for maintaining, supervising or reviewing any of DTC's or its nominee's
records or any participant's records relating to the beneficial ownership
interests.

  A global security is exchangeable for definitive notes registered in the
name of, and a transfer of a global security may be registered to, any person
other than DTC or its nominee, only if:

  . DTC notifies us and the senior indenture trustee that it is unwilling or
    unable to continue as depositary for the global security, and a qualified
    successor depositary is not appointed by us within 90 days;

  . at any time DTC ceases to be a clearing agency registered under the
    Securities Exchange Act of 1934 and a qualified successor depositary is
    not appointed by us within 90 days;

                                     S-31
<PAGE>

  . an event of default has occurred and is continuing; or

  . we determine, in our sole discretion, that the global security shall be
    exchangeable for definitive notes in registered form.

  DTC is a limited-purpose trust company organized under the New York Banking
Law, a "banking organization" within the meaning of the New York Banking Law,
a member of the Federal Reserve System, a "clearing corporation" within the
meaning of the New York Uniform Commercial Code and a "clearing agency"
registered pursuant to the provisions of Section 17A of the Exchange Act. DTC
was created to hold securities of its participants and to facilitate the
clearance and settlement of securities transactions, such as transfers and
pledges, among its participants in securities through electronic computerized
book-entry changes in accounts of the participants, thereby eliminating the
need for physical movement of securities certificates. Participants include
brokers, dealers, banks, trust companies, clearing corporations and other
organizations, some of whom own DTC. Access to DTC's book-entry system is also
available to others, such as banks, brokers, dealers and trust companies that
clear through or maintain a custodial relationship with a participant, either
directly or indirectly. Persons who are not participants may beneficially own
securities held by DTC only through participants.

Certain Covenants in the Senior Indenture

  Neither Mutual Group nor MRM will sell, transfer or otherwise dispose of any
shares of capital stock of a significant subsidiary, and neither Mutual Group
nor MRM will permit any significant subsidiary to sell, transfer or otherwise
dispose of any shares of capital stock of any other significant subsidiary,
unless the entire capital stock of the significant subsidiary at the time
owned by MRM or Mutual Group, as the case may be, and its significant
subsidiaries is disposed of at the same time for consideration consisting of
cash or other property, which, in the opinion of MRM's or Mutual Group's board
of directors, as the case may be, determined in good faith, is at least equal
to the fair market value of the significant subsidiary and the transaction is
in compliance with the merger provisions described in the accompanying
prospectus.

  Neither MRM nor Mutual Group will, and neither MRM nor Mutual Group will
permit any significant subsidiary at any time directly or indirectly to,
create, assume, incur or otherwise permit to exist any indebtedness secured by
a pledge, lien or other encumbrance on any shares of the capital stock of any
significant subsidiary, other than existing indebtedness that is so secured
and any renewals, extensions or refundings of that indebtedness, without
making effective provisions whereby the senior notes then outstanding, and, if
MRM or Mutual Group, as the case may be, elects, any other indebtedness
ranking equally with the senior notes, will be secured equally and ratably
with or prior to that other indebtedness so long as that other indebtedness is
secured.

  "Significant subsidiary" means any subsidiary of MRM, the assets of which
constitute at least 10% of MRM's consolidated total assets or the income
before income taxes and minority interest of which accounts for at least 10%
of MRM's consolidated income before income taxes and minority interest.

Defeasance

  The indenture provisions relating to satisfaction and discharge and legal
and covenant defeasance that are described in the accompanying prospectus
under the caption "Description of the Senior Notes and the MRM Senior Note
Guarantees--Defeasance and Covenant Defeasance" will apply to the senior
notes.

Concerning the Trustee

  MRM, Mutual Group and certain of their affiliates maintain banking
relationships in the ordinary course of business with The Chase Manhattan
Bank.

Paying Agent and Registrar

  The Chase Manhattan Bank will act as paying agent and registrar for the
senior notes.

</TABLE>

  The underwriting agreement provides that the obligation of the underwriters
to pay for and accept delivery of the senior notes offered hereby is subject
to specified conditions, including delivery of legal opinions by MRM's and
Mutual Group's counsel. Subject to the terms and conditions of the
underwriting agreement, the underwriters are committed to take and pay for all
of the senior notes offered hereby if any are taken.

  The underwriters have advised Mutual Group that they propose to offer the
senior notes initially at the initial public offering price set forth on the
cover page of this prospectus supplement, that the underwriters may allow to
selected dealers a concession of       % of the offering price and that the
dealers may reallow a concession not in excess of        % of the offering
price to other dealers. After the initial public offering, the offering price
and the concessions may be changed by the underwriters.

  There is no established trading market presently in existence for the senior
notes and, although the underwriters have advised us that they currently
intend to make a market in the senior notes, they are not obligated to do so
and any market making may be discontinued at any time, without notice, in the
sole discretion of the underwriters. In addition, any market making activity
will be subject to the limits imposed by the Securities Act and the Exchange
Act. The senior notes are not listed on a national securities exchange or
authorized for trading on the National Association of Securities Dealers
Automated Quotation System. No assurance can be given as to the development of
liquidity of any market that may develop for the senior notes.

  The underwriting agreement provides that we will indemnify the underwriters
and their respective controlling persons against specified liabilities,
including liabilities under the Securities Act, or will contribute to payments
that the underwriters may be required to make in respect thereof.

  In connection with the offering, the underwriters may engage in
overallotment, stabilizing transactions and syndicate covering transactions
and penalty bids. Overallotment involves sales in excess of the offering size,
which creates a short position for the underwriters. Stabilizing transactions
involve bids to purchase the senior notes in the open market for the purpose
of pegging, fixing and monitoring the price of the senior notes in the open
market, and these types of transactions will be effected in compliance with
Rule 104 of Regulation M promulgated under the Securities Act. Short covering
transactions involve the purchase of senior notes in the open market after the
distribution has been completed in order to cover short positions. Penalty
bids permit the underwriters to reclaim a selling concession from a dealer
when senior notes originally sold by the dealer are purchased in a covering
transaction to cover short positions. These types of stabilizing transactions,
short covering transactions and penalty bids may cause the price of the senior
notes to be higher than it would otherwise be in the absence of these types of
stabilizing transactions. The underwriters are not required to engage in these
activities, and may discontinue them at any time.

  Expenses associated with this offering to be paid by us are estimated to be
$950,000.

                             ABOUT THIS PROSPECTUS

   This prospectus is part of a "shelf" registration statement that we filed
with the SEC. By using this shelf registration statement, we may sell up to
$500,000,000 of any combination of the securities described in this prospectus
from time to time and in one or more offerings. This prospectus only provides
you with a general description of the securities that we may offer. Each time
we sell securities, we will provide a supplement to this prospectus that
contains specific information about the terms of the securities. Before
purchasing any securities, you should carefully read both this prospectus and
any supplement, together with the additional information described under the
heading "Where You Can Find More Information."

   MRM Capital Trust I, MRM Capital Trust II and MRM Capital Trust III, each of
which is referred to in this prospectus as a trust and all of which are
collectively referred to as the trusts, have no independent function other than
to issue securities and to purchase junior subordinated notes. Mutual Group
Ltd., referred to in this prospectus as Mutual Group, is a wholly-owned
subsidiary of Mutual Risk Management Ltd., referred to in this prospectus as
MRM. This prospectus does not contain separate financial statements for Mutual
Group or the trusts. MRM files consolidated financial information with the SEC
that includes condensed consolidating information regarding Mutual Group and
will include other financial information regarding the trusts.

   You should rely only on the information contained or incorporated by
reference in this prospectus and in any supplement. "Incorporate by reference"
means that we can disclose important information to you by referring you to
another document filed separately with the SEC. We have not authorized any
other person to provide you with different information. If anyone provides you
with different or inconsistent information, you should not rely on it. We will
not make an offer to sell these securities in any jurisdiction where the offer
or sale is not permitted. You should assume that the information appearing in
this prospectus and any supplement to this prospectus is current only as of the
dates on their covers. Our business, financial condition, results of operations
and prospects may have changed since that date.

              CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

   This prospectus, any prospectus supplement and the information incorporated
by reference in them may contain forward-looking statements within the meaning
of the federal securities laws. MRM intends these forward-looking statements to
be covered by the safe harbor provisions for forward-looking statements in
these sections. In some cases, you can identify these statements by our use of
forward-looking words such as "may," "will," "should," "anticipate,"
"estimate," "expect," "plan," "believe," "predict," "potential" and "intend."
You should be aware that these statements and any other forward-looking
statements in these documents only reflect our expectations and are not
guarantees of performance. These statements involve risks, uncertainties and
assumptions. Actual events or results may differ materially from our
expectations. Important factors that could cause our actual results to be
materially different from our expectations include those discussed in any of
these documents under the caption "Risk Factors." The safe harbor provisions
for forward-looking statements only apply to companies that have previously
offered securities to the public. Because Mutual Group's offer of the senior
notes and junior subordinated notes and each trust's offer of the preferred
securities constitutes Mutual Group's and each trust's initial public offering
of securities, the safe harbor provisions of the federal securities laws do not
apply to Mutual Group or the trusts. We undertake no obligation to update or
revise publicly any forward-looking statements, whether as a result of new
information, future events or otherwise.

                          MUTUAL RISK MANAGEMENT LTD.

   We provide risk management services to clients in the United States, Canada
and Europe that seek alternatives to traditional commercial insurance for risk
exposures. In addition, we provide financial services to offshore mutual funds
and other companies. We are a Bermuda-based insurance holding company that was
incorporated in 1977. We primarily focus on the "alternative market," which
involves clients self-insuring a significant amount of their loss exposure and
transferring only the unpredictable excess risk to insurers. Although revenue
earned from premiums is substantial, our principal source of profits is from
fees received for the various insurance and other services provided to clients
in connection with our programs. Income from fees is derived from four distinct
business segments:

  Program Business--The largest of our business segments. In this segment, we
  replace traditional insurers as the conduit between producers of specialty
  books of business and reinsurers wishing to write that business. We provide
  a range of services for a fee and the underwriting profit is shared between
  the producer and the reinsurers.

  Corporate Risk Management--Our original business segment. Corporate Risk
  Management involves providing services to businesses and associations
  seeking to insure a portion of their risk in a loss sensitive alternative
  market structure. We earn our fees by designing and implementing risk
  financing and loss control programs for medium-size and large companies
  that seek to insure a portion of their insurable risk.

  Specialty Brokerage--Our Specialty Brokerage segment specializes in placing
  reinsurance for captive insurance companies, placing coverage with excess
  liability and corporate officers' and directors' liability carriers and
  placing reinsurance in connection with our Program and Corporate Risk
  Management businesses.

  Financial Services--Our Financial Services segment started in 1996 with the
  acquisition of The Hemisphere Group Limited. The Financial Services segment
  provides administrative services to offshore mutual funds and other
  companies and offers a proprietary family of mutual funds as well as asset
  accumulation life insurance products for the high net worth market.

   The structure of our programs places most of the underwriting risk with the
client or our reinsurers. For regulatory and other reasons, however, we are
required to assume a limited amount of risk. We seek to limit our risk to the
minimum level feasible. This approach to risk distinguishes us from typical
property/casualty companies that assume significant levels of underwriting risk
as part of their businesses. We do not seek to earn income from underwriting
risk, but rather from fees for services provided.

   MRM's principal executive offices are located at 44 Church Street, Hamilton
HM 12 Bermuda and its telephone number is (441) 295-5688.

                               MUTUAL GROUP LTD.

   Mutual Group is a holding company for our U.S. operations. Its principal
operating subsidiaries are Legion Insurance Company, Legion Indemnity Company
and Villanova Insurance Company. Mutual Group was incorporated in 1979. Its
principal executive offices are located at One Logan Square, Suite 1500,
Philadelphia, Pennsylvania 19103 and its telephone number is (215) 963-1600.

<PAGE>

                                   THE TRUSTS

   Mutual Group created each trust as a statutory Delaware business trust
pursuant to a trust agreement. Mutual Group will enter into an amended and
restated trust agreement for each trust, which will state the terms and
conditions for the trust to issue and sell its preferred securities and common
securities.

   Each trust exists solely to:

  . issue and sell to the public preferred securities, representing undivided
    beneficial interests in the assets of the trust;

  . issue and sell to Mutual Group common securities, representing undivided
    beneficial interests in the assets of the applicable trust;

  . use the gross proceeds from the sale of its preferred and common
    securities to purchase a series of junior subordinated notes;

  . distribute the cash payments it receives from the junior subordinated
    notes it owns to the holders of the preferred and common securities; and

  . engage in other activities that are necessary or incidental to these
    purposes.

   Mutual Group will purchase all of the common securities of each trust. The
common securities will represent an aggregate liquidation amount equal to at
least 3% of each trust's total capitalization. The preferred securities will
represent the remaining approximately 97% of each trust's total capitalization.
The common securities will have terms substantially identical to, and will rank
equal in priority of payment with, the preferred securities. Payments will be
made on both the common securities and the preferred securities when payments
of interest are made on the junior subordinated notes, upon redemption of the
junior subordinated notes or in some circumstances upon liquidation of the
trust. However, if a default on the payments on the related junior subordinated
notes occurs, then cash distributions and redemption, liquidation and other
amounts payable on the common securities will be subordinate in priority of
payment to the amounts payable on the preferred securities.

   Each of the trusts is a legally separate entity and the assets of one are
not available to satisfy the obligations of any of the others.

   The preferred securities will be guaranteed by MRM as described later in
this prospectus.

   We have appointed five trustees to conduct each trust's business and
affairs:

  . The Chase Manhattan Bank, which will act as the property trustee;

  . Chase Manhattan Bank Delaware, which will act as the Delaware trustee;
    and

  . Three Mutual Group officers, who will act as the administrative trustees.

   Mutual Group and MRM will pay all fees and expenses related to each trust
and the offering of the preferred securities and will pay all ongoing costs,
expenses and liabilities of each trust, except the trusts' obligations under
the preferred and common securities.

   The trusts will not have separate financial statements. The statements would
not be material to holders of the preferred securities because the trusts will
not have any independent operations and exist solely for the reasons summarized
above.

   The principal offices of each trust will be located at One Logan Square,
Suite 1500, Philadelphia, Pennsylvania 19103, and the telephone number of each
trust will be (215) 963-1600.

                                  RISK FACTORS

   You should carefully consider the following risk factors, in addition to the
other information provided in this prospectus and the accompanying prospectus
supplement, before you purchase any securities.

New insurance legislation in some states has increased competition, which has
reduced our fee revenues and made sales and renewals more difficult.

   Beginning in 1993, legislative reforms designed to reduce the cost of
workers' compensation insurance in some important workers' compensation markets
caused competition to increase significantly. This heightened level of
competition has persisted. Increased competition has lowered the premium rates
that we may charge, which has reduced our fee revenue. Increased competition
also has made sales and renewals of our programs more difficult. Workers'
compensation reform, to the extent it reduces premiums and introduces relative
stability in the traditional workers' compensation market, may reduce the
appeal of alternative market products such as those offered by us.

If we are unable to purchase reinsurance and transfer risk to reinsurers, our
net income would be reduced or we could incur a loss.

   A significant feature of our risk management programs is the utilization of
reinsurance to transfer all or a portion of risk not retained by the insured.
The availability and cost of reinsurance is subject to market conditions, which
are outside of our control. As a result, we may not be able to successfully
purchase reinsurance and transfer risk through reinsurance arrangements. A lack
of available reinsurance would adversely affect the marketing of our programs
and/or force us to retain all or a part of the risk that cannot be reinsured.
If we were required to retain these risks and ultimately pay claims with
respect to these risks, our net income would be reduced or we could incur a
loss. In addition, we are subject to credit risk with respect to our reinsurers
because the transfer of risk to a reinsurer does not relieve us of our
liability to the insured. The failure of a reinsurer to honor its obligations
would reduce our net income or could cause us to incur a loss.

If the issuers of letters of credit and clients fail to honor their
obligations, our net income would be reduced or we could incur a loss.

   Each of our clients chooses a level of risk retention, which is reinsured
either by one of our foreign reinsurance subsidiaries or by the client's
captive insurance company. This retention is generally also supported by
letters of credit. In addition, we rely extensively on letters of credit issued
or confirmed by a bank in order to secure a portion of the client's obligation
to reimburse us for losses on a program. The failure of a bank to honor its
letter of credit or the inability of a client to honor its uncollateralized
reimbursement obligation would reduce our net income or could cause us to incur
a loss.

If tax laws prevent our IPC Program participants from deducting premiums paid
to us, we would be unable to competitively market this program.

   One of our major products is the Insurance Profit Center Program, referred
to in this prospectus as the IPC Program. The IPC Program, frequently referred
to as a "rent-a-captive," was designed to provide clients some of the benefits
available through captive insurance companies without the administrative cost
and capital commitment necessary to establish and operate a captive insurance
company. The tax treatment of this program is not clear and varies
significantly with the circumstances of each IPC Program participant. However,
some participants deduct the premiums paid to us for federal income tax
purposes. A determination that a significant portion of the IPC Program
participants are not entitled to deduct the premiums paid to us without a
similar determination as to competing products would adversely affect the
marketability of the IPC Program.


                                       5
<PAGE>

If our loss reserves are inadequate to meet our actual losses, our net income
would be reduced or we could incur a loss.

   We are required to maintain reserves to cover our estimated ultimate
liability losses and loss adjustment expenses for both reported and unreported
claims incurred. These reserves are only estimates of what we think the
settlement and administration of claims will cost based on facts and
circumstances then known to us. Because of the uncertainties that surround
estimating loss reserves and loss adjustment expenses, we cannot be certain
that ultimate losses will not exceed these estimates of loss and loss
adjustment reserves. If our reserves are insufficient to cover our actual
losses and loss adjustment expenses, we would have to increase our reserves and
our net income would be reduced or we could incur a loss.

Insurance laws and regulations restrict our ability to operate.

   We are subject to extensive regulation under state and foreign insurance
laws. These laws limit the amount of dividends that can be paid by our
operating subsidiaries, impose restrictions on the amount and type of
investments that they can hold, prescribe solvency standards that must be met
and maintained by them and require them to maintain reserves. These laws also
require disclosure of material transactions by MRM and require prior approval
of certain "extraordinary" transactions. These "extraordinary" transactions
include declaring dividends that exceed statutory maximums from operating
subsidiaries to MRM or purchases of an operating subsidiary's capital stock.
These laws also generally require approval of changes of control. Our failure
to comply with these laws could subject us to fines and penalties and restrict
us from conducting business. The application of these laws could affect our
liquidity and ability to pay distributions and make payments on our debt
securities and could restrict our ability to expand our business operations
through acquisitions involving our insurance subsidiaries.

Our holding company structure could prevent us from paying distributions and
making payments on our debt securities.

   MRM is a holding company with no assets other than the stock of Mutual Group
and other holding companies. Mutual Group is a holding company with no assets
other than the stock of its operating subsidiaries. Our ability to meet our
obligations on our securities will be dependent on the earnings and cash flows
of our subsidiaries and the ability of the subsidiaries to pay dividends or to
advance or repay funds to us. Payment of dividends and advances and repayments
from our operating subsidiaries are regulated by state and foreign insurance
laws and regulatory restrictions, including minimum solvency and liquidity
thresholds. Accordingly, our operating subsidiaries may not be able to pay
dividends or advance or repay funds to us in the future, which could prevent us
from paying distributions and making payments on our debt securities.

Our ability to generate the cash needed to pay distributions and make payments
on our debt securities depends on many factors beyond our control.

   Our ability to pay distributions and make payments on our debt securities
will depend on our ability to generate cash and to secure financing in the
future. This ability is subject to general economic, financial, competitive,
regulatory and other factors beyond our control. If our business does not
generate sufficient cash flow from operations, and sufficient future borrowings
are not available to us, we may not be able to pay distributions and make
payments on our debt securities.

Our investment objectives may not be realized.

   The success of our investment objectives is affected by general economic
conditions that are outside of our control. General economic conditions can
adversely affect the markets for interest-rate-sensitive securities, including
the extent and timing of investor participation in those markets, the level and
volatility of interest rates and, consequently, the value of fixed income
securities. We may not be able to realize our investment objectives, which
could reduce our net income or cause us to incur a loss.

Our industry is highly competitive and we may not be able to compete
successfully in the future.

   Our industry is highly competitive and has experienced severe price
competition over the last several years. We compete in the United States and
international markets with domestic and international insurance companies. Some
of these competitors have greater financial resources than we do, have been
operating for longer than we have and have established long-term and continuing
business relationships throughout the industry, which can be a significant
competitive advantage. In addition, we expect to face further competition in
the future. We may not be able to compete successfully in the future.

We are dependent on our key personnel.

   Our success has been, and will continue to be, dependent on our ability to
retain the services of our existing key executive officers and to attract and
retain additional qualified personnel in the future. The loss of the services
of any of our key executive officers or the inability to hire and retain other
highly qualified personnel in the future could adversely affect our ability to
conduct our business.

You may not be able to recover damages from MRM and some of its directors,
officers and experts named in this prospectus if you sue them.

   MRM is organized under the laws of Bermuda. Some of its directors and
officers, as well as some of the experts named in this prospectus, may reside
outside the United States. A substantial portion of the assets of MRM and its
directors and officers are or may be located in jurisdictions outside the
United States. You may not be able to effect service of process within the
United States on directors and officers of MRM and those experts who reside
outside the United States. You also may not be able to recover against them or
MRM on judgments of U.S. courts or to obtain original judgments against them or
MRM in Bermuda courts, including judgments predicated upon civil liability
provisions of the U.S. federal securities laws.

If U.S. tax law changes, our net income may be reduced.

   Some members of Congress have recently expressed concern over a competitive
advantage that foreign-controlled insurers and reinsurers may have over U.S.-
controlled insurers and reinsurers due to the purchase of reinsurance by U.S.
insurers from affiliates operating in some foreign jurisdictions, including
Bermuda. Legislation has been proposed that would increase the U.S. tax burden
on some of these transactions. We do not know whether this legislation will
ever be enacted into law. If it were enacted, the U.S. tax burden on some
business ceded from our licensed U.S. insurance subsidiaries, including Legion
Insurance Company, Legion Indemnity Ltd. and Villanova Insurance Company, to
some offshore reinsurers could be increased. This could reduce our net income.

                                USE OF PROCEEDS

   We may sell all or a portion of the $500,000,000 of securities described in
this prospectus. Unless stated otherwise in the applicable prospectus
supplement, the net proceeds from the sale of the securities offered by each
trust will be used by the trust to purchase a series of junior subordinated
notes. Unless stated otherwise in the applicable prospectus supplement, MRM and
Mutual Group will use the net proceeds for general corporate purposes.

                       RATIO OF EARNINGS TO FIXED CHARGES

   The following table sets forth the ratio of earnings to fixed charges for
MRM for each of the periods indicated:

(1) For purposes of computing the consolidated ratio of earnings to fixed
    charges, "earnings" represents income before income taxes, minority
    interest, extraordinary items and fixed charges, and "fixed charges"
    includes gross interest expense, the proportion deemed representative of
    the interest factor of rent expense and preferred share dividend
    requirements of consolidated subsidiary companies.

                              ACCOUNTING TREATMENT

   Each trust will be treated as a wholly-owned subsidiary of MRM for financial
reporting purposes. Accordingly, each trust's financial statements will be
included in the consolidated financial statements of MRM. The preferred
securities of each trust will be presented as a separate line item in the
consolidated statements of financial position of MRM under the caption
"Minority Interest--Company Obligated Mandatorily Redeemable Preferred
Securities of Subsidiary Trust Holding Solely Junior Subordinated Notes of the
Company" and appropriate disclosures about the preferred securities will be
included in the notes to the consolidated financial statements. Specifically,
MRM will record distributions payable on the preferred securities as minority
interest in the consolidated statements of operations of MRM, include in a
footnote to its financial statements disclosure that the sole assets of each
trust are the junior subordinated notes and specify the principal amount,
interest rate and maturity date of the junior subordinated notes held.

   The Financial Accounting Standards Board is in the process of drafting a
proposed exposure draft on liabilities and equity. The proposed exposure draft,
if issued, could alter the accounting treatment described above by requiring
the preferred securities of each trust to be classified as debt on the
consolidated statements of financial position of MRM and the related
distributions payable as a component of interest expense in the consolidated
statements of operations of MRM.

    DESCRIPTION OF THE SENIOR NOTES AND THE MRM SENIOR NOTE GUARANTEES

   The senior notes of MRM will be issued pursuant to a senior indenture, as
supplemented from time to time, between MRM and The Chase Manhattan Bank, as
the senior indenture trustee. The senior notes of Mutual Group will be issued
pursuant to a senior indenture, as supplemented from time to time, among Mutual
Group, MRM, as guarantor, and The Chase Manhattan Bank, as senior indenture
trustee. We have filed the base senior indentures as exhibits to the
registration statement of which this prospectus is a part. You also may request
a copy of the senior indentures from the senior indenture trustee at its
corporate trust office in New York, New York. Each senior indenture will be
qualified under the Trust Indenture Act of 1939. The terms of each series of
senior notes will include those stated in the senior indenture for that series
and those made part of the senior indenture by reference to the Trust Indenture
Act.

   MRM and Mutual Group, each referred to as the issuing company, may each
issue series of senior notes from time to time by entering into supplemental
indentures with the senior indenture trustee or pursuant to resolutions of its
board of directors or a duly authorized committee of its board. Any
supplemental indenture or resolutions of either its board of directors or a
duly authorized committee of its board will be executed at the time the issuing
company issues any senior notes and will be filed with the SEC on Form 8-K or
by a post-effective amendment to the registration statement of which this
prospectus is a part.

General

   The base senior indentures do not limit the aggregate principal amount of
senior notes that the issuing company may issue. The senior notes of a series
need not be issued at the same time, bear interest at the same rate or mature
on the same date.

   The applicable prospectus supplement and the applicable supplemental
indenture or resolutions for a particular series of senior notes will set forth
the following terms of that series:

  . the title of the series;

  . any limit on the aggregate principal amount of the senior notes of the
    series;

  . the date or dates on which the principal of any of the senior notes of
    the series will be payable or the method for determining the date or
    dates;

  . whether the issuing company may shorten or extend the date on which the
    principal of any senior notes of the series is payable and, if so, the
    terms and conditions of any extension;

  . the rate or rates at which any of the senior notes of the series will
    bear interest, if any, or the method for determining the rate or rates,
    and the date or dates from which any interest will accrue;

  . the interest payment dates on which any interest will be payable and the
    regular record date, if any, for any interest payable on any interest
    payment date;

  . whether the senior notes will be secured or unsecured;

  . the place or places where payments on any of the senior notes of the
    series will be payable, if other than the principal corporate trust
    office of the senior indenture trustee;

  . the issuing company's obligation, if any, to redeem or purchase the
    senior notes of the series pursuant to any sinking fund, amortization or
    analogous provision and the terms and conditions on which any of the
    senior notes may be redeemed or purchased pursuant to any obligation;

  . the terms and conditions, if any, on which the senior notes of the series
    may be redeemed at the issuing company's option or at the option of the
    holder;

  . any index or formula for determining the amount of principal or any
    premium or interest on any of the senior notes of the series and the
    manner of determining those amounts;

  . the currency, currencies or currency units in which payments on any of
    the senior notes of the series will be payable, if other than U.S.
    dollars, and the manner of determining the equivalent of those amounts in
    U.S. dollars for any purpose;

                                       9
<PAGE>


  . if the payments on the senior notes of the series are payable, at the
    issuing company's option or the option of the holder of the senior notes,
    in one or more currencies or currency units other than those in which the
    senior notes are stated to be payable, the currency, currencies or
    currency units in which the payments on the senior notes may be payable
    and the terms and conditions of the option;

  . the portion of the principal amount of any of the senior notes of the
    series that will be payable upon declaration of acceleration of maturity,
    if other than the entire principal amount;

  . whether any of the terms of the senior indenture described below under
    "--Defeasance and Covenant Defeasance" will not apply to any of the
    senior notes of the series;

  . whether any of the senior notes of the series will be issuable as global
    securities and, if so, the depositary and any provisions for the transfer
    or exchange of any such global securities, if different from those
    described below under "--Global Securities";

  . any addition to, deletion from or change in events of default or
    covenants with respect to any of the senior notes of the series and any
    change in the right of the senior indenture trustee or the holders of the
    senior notes to accelerate the maturity of the senior notes; and

  . any other terms of the senior notes of the series.

   Unless the applicable prospectus supplement states otherwise, the issuing
company will issue the senior notes only in fully registered form, without
coupons, and there will be no service charge for any registration of transfer
or exchange of the senior notes. The issuing company may, however, require
payment to cover any tax or other governmental charge payable in connection
with the registration of transfer or exchange.

   The issuing company may offer and sell the senior notes at a substantial
discount below their principal amount and the senior indenture does not provide
any limit on the amount by which the issuing company may discount the senior
notes. The applicable prospectus supplement will describe the special United
States federal income tax and other considerations, if any, applicable to any
discounted senior notes. In addition, the applicable prospectus supplement may
describe certain special United States federal income tax or other
considerations, if any, applicable to any senior notes that are denominated in
a currency or currency unit other than U.S. dollars.

Ranking

   Unless the applicable prospectus supplement provides otherwise, the senior
notes will be unsecured indebtedness of the issuing company. The senior notes
will be equal in right of payment with any other senior indebtedness of the
issuing company and senior in right of payment to any subordinated indebtedness
of the issuing company. The senior notes will be effectively subordinated to
any secured indebtedness of the issuing company to the extent of the value of
the assets securing the secured indebtedness. As a result, in the event of the
issuing company's bankruptcy, liquidation or reorganization or upon
acceleration of the senior notes due to an event of default, the issuing
company's assets will be available to pay its obligations on the senior notes
only after all secured indebtedness has been paid in full in cash or other
payment satisfactory to the holders of the secured indebtedness has been made.
There may not be sufficient assets remaining to pay amounts due on any or all
of the senior notes then outstanding. The senior notes will also effectively be
subordinated to the indebtedness and other liabilities of the issuing company's
subsidiaries. The senior indentures do not prohibit or limit the incurrence of
secured or senior indebtedness or the incurrence of other indebtedness and
liabilities by the issuing company or its subsidiaries other than as described
below. The incurrence of additional senior indebtedness and other liabilities
by the issuing company or its subsidiaries could adversely affect the issuing
company's ability to pay the obligations on the senior notes.

MRM Senior Note Guarantee

   Unless provided otherwise in a prospectus supplement, MRM will fully and
unconditionally guarantee all obligations with respect to each series of senior
notes issued by Mutual Group. Unless provided otherwise in a

                                       10
<PAGE>

prospectus supplement, each MRM senior note guarantee will be unsecured
indebtedness of MRM and will be equal in right of payment to all of MRM's
existing and future senior indebtedness and senior in right of payment to any
subordinated indebtedness of MRM. Each MRM senior note guarantee will be
effectively subordinated to any secured indebtedness of MRM to the extent of
the value of the assets securing the secured indebtedness. Each MRM senior note
guarantee will also rank equally with any other MRM senior note guarantee of
any series of senior notes issued by Mutual Group. As a result, in the event of
MRM's bankruptcy, liquidation or reorganization or upon acceleration of any
series of senior notes due to an event of default, MRM's assets will be
available to pay MRM's obligations on an MRM senior note guarantee only after
all secured indebtedness of MRM has been paid in full in cash or other payment
satisfactory to the holders of the secured indebtedness of MRM has been made.
There may not be sufficient assets remaining to pay amounts due on any or all
of the MRM senior note guarantees. Each MRM senior note guarantee will also be
effectively subordinated to the indebtedness and other liabilities of MRM's
subsidiaries. Each MRM senior note guarantee does not prohibit or limit the
incurrence of secured or additional senior indebtedness or the incurrence of
other indebtedness and liabilities by MRM or its subsidiaries. The incurrence
of additional secured and senior indebtedness and other liabilities by MRM or
its subsidiaries could adversely affect MRM's ability to pay its obligations on
an MRM senior note guarantee.

  Each MRM senior note guarantee will constitute a guarantee of payment and not
of collection. This means that the holder of the guaranteed security may sue
MRM to enforce its rights under the MRM senior note guarantee without first
suing any other person or entity.

Additional Amounts

   MRM will make all payments on any series of senior notes issued by MRM and
all payments under each MRM senior note guarantee without withholding or
deduction for any taxes, fees, duties, assessments or governmental charges
imposed or levied by Bermuda or any other jurisdiction in which MRM or any
successor is organized or resident for tax purposes or any political
subdivision or taxing authority of Bermuda or any of those other jurisdictions.
If any withholding or deduction is required by law, MRM will pay to the holder
of the senior notes additional amounts as may be necessary so that every net
payment made to the holder after the withholding or deduction will not be less
than the amount provided for in the applicable senior note and the senior
indenture. MRM will not be required to pay any additional amounts as a result
of:

  . the imposition of any tax, fee, duty, assessment or governmental charge
    that would not have been imposed but for the fact that the holder or
    beneficial owner of the senior note was a resident or national of or had
    other specified connections with the relevant taxing jurisdiction or
    presented the senior note for payment in the relevant taxing jurisdiction
    unless it could not have been presented elsewhere;

  . the imposition of any tax, fee, duty, assessment or governmental charge
    that would not have been imposed but for the fact that the holder or
    beneficial owner of the senior note presented the senior note for payment
    more than 30 days after it was due and payable;

  .  any estate, inheritance, gift, sale, transfer, personal property or
     similar tax, fee, duty, assessment or other governmental charge; or

  . the imposition of any tax, fee, duty, assessment or governmental charge
    that would not have been imposed but for the fact that the holder or
    beneficial owner of the senior note failed to comply, within 90 days,
    with any reasonable request by MRM addressed to the holder or beneficial
    owner relating to the provision of information or the making of a
    declaration required by the taxing jurisdiction as a precondition to
    exemption from all or part of the tax, fee, duty, assessment or
    governmental charge.

   In addition, MRM will not be required to pay additional amounts with respect
to any payment to any holder of a senior note where the beneficial owner of the
senior note is a fiduciary or partnership to the extent that such payment would
be required to be included in the income for tax purposes of a beneficiary with
respect to such fiduciary or a partner of such partnership that would not have
been entitled to such additional amounts if it had been the holder of the
senior note.

Global Securities

   Some or all of the senior notes of a series may be represented in whole or
in part by one or more global securities deposited with or on behalf of one or
more depositaries. The applicable prospectus supplement will describe the terms
of any depositary arrangement. Unless the applicable prospectus supplement
states otherwise, the following provisions will apply to all depositary
arrangements for any senior notes represented by global securities.

                                       11
<PAGE>


   Senior notes represented by a global security deposited with or on behalf of
a depositary will be registered in the name of that depositary or its nominee.
Upon the issuance of a global security in registered form, the depositary for
the global security will credit, on its book-entry registration and transfer
system, the respective principal amounts of the senior notes represented by the
global security to the accounts of institutions that have accounts with the
depositary or its nominee. These institutions are generally brokers, dealers,
banks and other financial institutions and are often referred to as
participants. The accounts to be credited will be designated by the
underwriters or agents of the senior notes or by the issuing company if the
senior notes are offered and sold directly by the issuing company. Ownership of
beneficial interests in the global securities will be limited to participants
or persons that may hold interests through participants. Any person who holds a
brokerage account with a participant may purchase the senior notes through the
participant. Ownership of beneficial interests by participants in the global
securities will be shown on, and the transfer of any ownership interest will be
effected only through, records maintained by the depositary or its nominee for
the global security. Ownership of beneficial interests in global securities by
persons that hold through participants will be effected only through records
maintained by the applicable participant. Some insurance companies and other
institutions are required by law to hold their investment securities in
definitive form, so an investor may not be able to sell its senior notes to
those entities.

   So long as the depositary for a global security or its nominee is the
registered owner of the global security, the depositary or the nominee, as the
case may be, will be considered the sole owner or holder of the senior notes
represented by the global security for all purposes under the senior indenture.
Except as set forth below, owners of beneficial interests in the global
security will not be entitled to have the senior notes represented by the
global security registered in their names, will not receive or be entitled to
receive physical delivery of the senior notes in definitive form and will not
be considered the owners or holders of the senior notes under the senior
indenture.

   Payments on senior notes registered in the name of or held by a depositary
or its nominee will be made in immediately available funds to the depositary or
its nominee, as the case may be, as the registered owner or the holder of the
global security representing the senior notes. None of the issuing company,
MRM, as guarantor, if applicable, the senior indenture trustee, any paying
agent or the registrar and transfer agent for the senior notes will have any
responsibility or liability for any aspect of the records relating to, or
payments made on account of, beneficial ownership interests in a global
security for the senior notes or for maintaining, supervising or reviewing any
records relating to the beneficial ownership interests.

   We expect that a depositary for the senior notes of a series, upon receipt
of any payments in respect of a global security, will immediately credit
participants' accounts with payment in amounts proportionate to their
respective beneficial interests in the principal amount of the global security
as shown on the records of the depositary. We also expect that payments by
participants to owners of beneficial interests in the global security held
through the participants will be governed by standing instructions and
customary practices, as is now the case with securities held for the accounts
of customers registered in "street name," and will be the responsibility of
each participant.

   So long as the depositary for a global security or its nominee is the
registered owner of the global security, the depositary or its nominee, as the
case may be, will be entitled to direct the actions of the senior indenture
trustee upon an event of default. However, we expect that a depositary for the
senior notes of a series, upon receiving notice of an event of default, will
immediately solicit the participants regarding any action to be taken. We also
expect that the participants will act in accordance with standing instructions
and customary practices, as is now the case with securities held for the
accounts of customers registered in "street name," and will, in turn, solicit
the owners of the beneficial interests regarding any action to be taken upon
any event of default.

   A global security may not be transferred, in whole or in part, except by the
depositary for the global security to a nominee of the depositary or by a
nominee of the depositary to the depositary or another nominee of the
depositary or by the depositary or any nominee to a successor depositary or a
nominee of the successor

                                       12
<PAGE>


depositary. If a depositary for the senior notes of a series is at any time
unwilling or unable to continue as depositary and a qualified successor
depositary is not appointed by the issuing company within 90 days or if at any
time the depositary ceases to be a clearing agency registered under the
Exchange Act when the depositary is required to be registered to act as the
depositary and no qualified successor is appointed by the issuing company
within 90 days or if an event of default has occurred and is continuing, then
the issuing company will issue the senior notes in definitive registered form
in exchange for the global security or global securities representing the
senior notes. In addition, the issuing company may, at any time, determine not
to have any senior notes represented by one or more global securities and, in
that event, will issue the senior notes in definitive registered form in
exchange for the global securities representing the senior notes. In any of
these instances, an owner of a beneficial interest in a global security will be
entitled to physical delivery in definitive form of the senior notes
represented by the global security equal in principal amount to its beneficial
interest and to have the senior notes registered in its name.

Covenants in the Senior Indenture

   The issuing company and, in the case of senior notes issued by Mutual Group
and guaranteed by MRM, MRM will not sell, transfer or otherwise dispose of any
shares of capital stock of a significant subsidiary, and the issuing company
and, in the case of senior notes issued by Mutual Group and guaranteed by MRM,
MRM will not permit any significant subsidiary to sell, transfer or otherwise
dispose of any shares of capital stock of any other significant subsidiary,
unless the entire capital stock of the significant subsidiary at the time owned
by MRM or Mutual Group, as the case may be, and its significant subsidiaries is
disposed of at the same time for consideration consisting of cash or other
property, which, in the opinion of MRM's or Mutual Group's board of directors,
as the case may be, determined in good faith, is at least equal to the fair
market value of the significant subsidiary and the transaction is in compliance
with the merger provisions described below.

   The issuing company and, in the case of senior notes issued by Mutual Group
and guaranteed by MRM, MRM will not, and the issuing company and, in the case
of senior notes issued by Mutual Group and guaranteed by MRM, MRM will not
permit any significant subsidiary at any time directly or indirectly to,
create, assume, incur or otherwise permit to exist any indebtedness secured by
a pledge, lien or other encumbrance on any shares of the capital stock of any
significant subsidiary, other than existing indebtedness that is so secured and
any renewals, extensions or refundings of that indebtedness, without making
effective provision whereby the senior notes then outstanding and any related
guarantee, and, if MRM or Mutual Group, as the case may be, elects, any other
indebtedness ranking equally with the senior notes and any related guarantee,
will be secured equally and ratably with or prior to that other indebtedness so
long as that other indebtedness is secured.

   "Significant subsidiary" means any subsidiary of MRM or Mutual Group, as the
case may be, the assets of which constitute at least 10% of MRM's or Mutual
Group's, as the case may be, consolidated total assets or the income before
income taxes and minority interest of which accounts for at least 10% of MRM's
or Mutual Group's, as the case may be, consolidated income before income taxes
and minority interest.

Events of Default

   The following will be events of default under the senior indenture with
respect to the senior notes of any series unless the particular event of
default is not applicable to the particular series or is modified or deleted in
a supplemental indenture as stated in the applicable prospectus supplement:

  . the issuing company fails to pay principal of or any premium on any
    senior note of that series, or any additional amounts related to
    principal or premium, on its due date;

  . the issuing company fails to pay any interest on any senior note of that
    series, or any additional amounts related to interest, within 30 days
    from its due date;

  . the issuing company fails to make any sinking fund payment on its due
    date;

                                       13
<PAGE>


  . the issuing company or, in the case of senior notes issued by Mutual
    Group and guaranteed by MRM, MRM fails to perform any of its covenants in
    the senior indenture, excluding a covenant not applicable to the affected
    series, for 30 days after the senior indenture trustee or the holders of
    at least 25% in principal amount of the outstanding senior notes of that
    series give the issuing company and MRM, as guarantor, if applicable,
    written notice of the default and require that the issuing company and
    MRM, as guarantor, if applicable, remedy the breach. However, the 30-day
    period may be extended by either the senior indenture trustee or the
    senior indenture trustee and the holders of at least the same principal
    amount of the outstanding senior notes of that series that had given
    notice of the default;

  . the issuing company or, in the case of senior notes issued by Mutual
    Group and guaranteed by MRM, MRM defaults under any (1) indebtedness for
    any money borrowed, including any other series of debt securities, (2)
    mortgage, indenture or other instrument under which there may be issued
    or may be secured or evidenced any indebtedness for money borrowed or (3)
    guarantee of payment for money borrowed, and any default consists of a
    payment default at the stated maturity of the indebtedness, after giving
    effect to any applicable grace period, or results in the indebtedness
    becoming due or being declared due prior to its stated maturity;
    provided, that a default shall exist under this clause only if the
    aggregate principal amount outstanding under all of the indebtedness that
    is so in default or that has become due or been declared due prior to its
    stated maturity, as the case may be, exceeds $40,000,000 and the default
    has not been cured, the indebtedness or accelerated indebtedness has not
    been discharged or the acceleration of the indebtedness has not been
    rescinded or annulled, in each case, within 10 days after the senior
    indenture trustee or the holders of at least 25% in principal amount of
    the senior notes give the issuing company and MRM, as guarantor, if
    applicable, written notice of the default and require that the issuing
    company and MRM, as guarantor, if applicable, remedy the breach;

  . the issuing company or, in the case of senior notes issued by Mutual
    Group and guaranteed by MRM, MRM fails within 60 days to pay, bond or
    otherwise discharge any uninsured judgment or court order for the payment
    of money in excess of $40,000,000, which is not stayed on appeal or is
    not otherwise being appropriately contested in good faith;

  . the issuing company or, in the case of senior notes issued by Mutual
    Group and guaranteed by MRM, MRM files for bankruptcy or other events of
    bankruptcy, insolvency or reorganization occur;

  . in the case of senior notes issued by Mutual Group and guaranteed by MRM,
    the guarantee ceases to be in full force and effect; and

  . any other event of default specified in the applicable prospectus
    supplement occurs.

   If the issuing company or, in the case of senior notes issued by Mutual
Group and guaranteed by MRM, MRM files for bankruptcy or other events of
bankruptcy, insolvency or reorganization occur, all unpaid principal and
accrued interest, premium and additional amounts on the senior notes will
automatically be immediately due and payable. If any other event of default
with respect to the senior notes of a series occurs and is continuing, then the
senior indenture trustee or the holders of not less than 25% in principal
amount of the outstanding senior notes of that series may, by notice to the
issuing company and, in the case of senior notes issued by Mutual Group and
guaranteed by MRM, MRM and to the senior indenture trustee if given by the
holders, declare to be immediately due and payable all unpaid principal and
accrued interest, premium and additional amounts on all senior notes of that
series.

   At any time after a declaration of acceleration has been made with respect
to the senior notes of a series and before a judgment or decree for payment of
the money due has been obtained, the holders of not less than a majority in
principal amount of the outstanding senior notes may rescind any declaration of
acceleration with respect to the senior notes and its consequences if:

  . the issuing company or, in the case of senior notes issued by Mutual
    Group and guaranteed by MRM, MRM deposits with the senior indenture
    trustee funds sufficient to pay all overdue principal of and any premium,
    interest and additional amounts due on the senior notes, any amounts due
    to the senior note trustee and, to the extent that payment of the
    interest is lawful, interest on the overdue interest and additional
    amounts; and

                                       14
<PAGE>

  . all existing events of default with respect to the senior notes have been
    cured or waived except non-payment of principal on the senior notes that
    has become due solely because of the acceleration.

   The holders of not less than a majority in principal amount of the
outstanding senior notes of any series have the right to direct the time,
method and place of conducting any proceedings for any remedy available to the
senior indenture trustee or to direct the exercise of any trust or power
conferred on the senior indenture trustee with respect to the senior notes of
that series.

   No holder of a senior note of any series will have any right to institute a
proceeding with respect to the senior indenture for the appointment of a
receiver or for any remedy under the senior indenture unless:

  . that holder has previously given the senior indenture trustee written
    notice that an event of default with respect to the senior notes of that
    series has occurred and is continuing;

  . the holders of not less than a majority in principal amount of the
    outstanding senior notes of that series have made written request to
    institute the proceeding;

  . the holder or holders have offered reasonable indemnity to the senior
    indenture trustee;

  . the senior indenture trustee has failed to institute the proceeding for
    60 days after receipt of the notice and offer of indemnity; and

  . the senior indenture trustee has not received from the holders of not
    less than a majority in principal amount of the outstanding senior notes
    of that series a direction inconsistent with the written request.

   Notwithstanding the foregoing, the holder of any senior note will have an
absolute and unconditional right to receive payment of the principal of and any
premium, interest and additional amounts on that senior note on its maturity
date, or, in the case of redemption, the date of redemption, and to institute
suit for the enforcement of any payment against the issuing company and MRM, as
guarantor, if applicable.

Notice of Default

   If an event occurs which is or would become an event of default with respect
to any series of the senior notes, and the senior indenture trustee knows of
the event, the senior indenture trustee shall mail to the holders of the
affected senior notes a notice of the default within 90 days, unless the
default has been cured or waived by the holders of the affected senior notes.
However, except in the case of a default in the payment of any amounts due on
senior notes of any series, the senior indenture trustee may withhold the
notice if and so long as the directors and/or responsible officers of the
senior indenture trustee determine in good faith that withholding the notice is
in the interest of the holders of the affected senior notes.

   The issuing company and, in the case of senior notes issued by Mutual Group
and guaranteed by MRM, MRM are required to furnish annually to the senior
indenture trustee an officers' certificate to the effect that, to the best
knowledge of the officers providing the certificate, the issuing company or
MRM, as guarantor, if applicable, is not in default under the senior indenture
or, if there has been a default, specifying the default and its status.

Consolidation, Merger, Conveyance or Transfer

   The Mutual Group senior indenture provides that Mutual Group may consolidate
or merge with or into another entity, or convey, transfer or lease its
properties and assets substantially as an entirety to any entity or permit an
entity to convey, transfer or lease its properties and assets substantially as
an entirety to it; provided, that:

  . the successor, if any, is a corporation organized and existing under the
    laws of the United States of America, any State of the United States or
    the District of Columbia and expressly assumes by supplemental indenture
    all of Mutual Group's obligations under the Mutual Group senior indenture
    and the related senior notes;

                                       15
<PAGE>


  . immediately after giving effect to the transaction, no event of default,
    or event which after notice or lapse of time or both would become an
    event of default, will have occurred and be continuing; and

  . Mutual Group delivers an officers' certificate and an opinion of counsel
    to the senior indenture trustee, each stating that the transaction
    complies with the Mutual Group senior indenture and all conditions
    precedent in the Mutual Group senior indenture relating to the
    consolidation, merger, conveyance or transfer have been complied with.

   Upon the assumption by the successor of Mutual Group's obligations under the
senior indenture and the senior notes, the successor will succeed to and be
substituted for Mutual Group under the Mutual Group senior indenture, and
Mutual Group will be relieved of all of its obligations under the Mutual Group
senior indenture and the related senior notes, except as otherwise specified in
any applicable prospectus supplement.

   Each senior indenture provides that MRM may consolidate or merge with or
into another entity, or convey, transfer or lease its properties and assets
substantially as an entirety to any entity or permit an entity to convey,
transfer or lease its properties and assets substantially as an entirety to it;
provided, that:

  . the successor, if any, is a corporation existing under the laws of the
    United States of America, any State of the United States, the District of
    Columbia or Bermuda and expressly assumes by supplemental indenture all
    of MRM's obligations under the applicable senior indenture and the
    related senior notes or the MRM senior note guarantee, as the case may
    be;

  . immediately after giving effect to the transaction, no event of default,
    or event which after notice or lapse of time or both would become an
    event of default, will have occurred and be continuing; and

  . MRM delivers an officers' certificate and an opinion of counsel to the
    senior indenture trustee, each stating that the transaction complies with
    the applicable senior indenture and all conditions precedent in the
    applicable senior indenture relating to the consolidation, merger,
    conveyance or transfer have been complied with.

   Upon the assumption by the successor of MRM's obligations under the
applicable senior indenture, the senior notes and the MRM senior note
guarantees, if applicable, the successor will succeed to and be substituted for
MRM under the applicable senior indenture, and MRM will be relieved of all of
its obligations under the senior indenture and the related senior notes and the
MRM senior note guarantees, if applicable, except as otherwise specified in the
applicable prospectus supplement.

Registration and Transfer

   If the senior notes of a series are to be redeemed, the issuing company will
not be required to:

  . issue, register the transfer of or exchange any senior notes of that
    series during the 15 days immediately preceding the date notice is mailed
    identifying the senior notes that are called for redemption; or

  . register the transfer of or exchange any senior note selected for
    redemption, in whole or in part, except for the unredeemed portion of a
    senior note being redeemed in part.

Denominations

   The senior notes will be issuable in denominations of $1,000 and any
integral multiples of $1,000, without coupons, unless the applicable prospectus
supplement states otherwise.

Payment and Paying Agent

   Principal of the senior notes will be paid only against surrender of the
senior notes as specified in the senior indenture. Unless the applicable
prospectus supplement states otherwise, interest on the senior notes will be
payable, at the issuing company's option, (1) by check mailed to the address of
the person entitled to the interest as the address appears in the security
register for the senior notes or (2) by wire transfer to an account at a
banking institution in the United States that the person entitled to the
interest designates in writing to the senior indenture trustee at least 10
business days prior to the date of payment.

                                       16
<PAGE>


   Unless the applicable prospectus supplement states otherwise, the senior
indenture trustee will act as paying agent for the senior notes, and the
principal corporate trust office of the senior indenture trustee will serve as
the office through which the paying agent acts. The issuing company may
designate additional paying agents, rescind the designation of any paying
agents and/or approve a change in the office through which any paying agent
acts.

Modification of the Senior Indentures

   The issuing company, MRM, as guarantor, if applicable, and the senior
indenture trustee may amend or modify the senior indentures with the consent of
the holders of at least a majority in aggregate principal amount of the
outstanding senior notes of each series of the senior notes affected by the
amendment or modification voting as a class. No amendment or modification may,
however, without the consent of the holder of each outstanding senior note
affected by the amendment or modification:

  . change the stated maturity of the principal of, or any premium, interest
    or additional amounts on, any senior note;

  . reduce the amount due and payable upon acceleration of the maturity of
    the senior note;

  . reduce the principal amount of, the rate of interest on or any premium
    payable upon the redemption of any senior note, modify the calculation of
    the rate of interest or change the date on which any senior note may be
    redeemed;

  . change MRM's obligations to pay any additional amounts;

  . change the place of payment or currency of any payment on any senior
    note;

  . impair the right to institute suit for the enforcement of any payment on
    any senior note on or after the stated maturity of the payment or date of
    redemption;

  . reduce the percentage in principal amount of the senior notes of any
    series, the consent of whose holders is required to amend or modify the
    senior indenture, to waive compliance with specific provisions of the
    senior indenture or to waive specific defaults;

  . modify the provisions of the MRM senior note guarantee; or

  . modify any of the above provisions.

   In addition, the issuing company, MRM, as guarantor, if applicable, and the
senior indenture trustee may, without the consent of any of the holders of the
senior notes, execute supplemental indentures to:

  . create new series of senior notes;

  . cure any ambiguity, correct or supplement any provision which may be
    inconsistent with any other provision or make provisions not inconsistent
    with any other provisions with respect to matters or questions arising
    under the applicable senior indenture, in each case to the extent that
    the amendment does not adversely affect the interests of any holder of
    the senior notes in any material respect; and

  . make other changes that do not adversely affect the interests of the
    holders of the senior notes in any material respect;

as well as for various other purposes.

Waiver of Covenants and Defaults

   The holders of not less than a majority in aggregate principal amount of the
outstanding senior notes of any series may waive, for that series, the issuing
company's and/or, in the case of senior notes issued by Mutual Group and
guaranteed by MRM, MRM's compliance with any restrictive covenants described in
this prospectus or in any prospectus supplement or included in any supplemental
indenture. The holders of not less than a majority in aggregate principal
amount of the outstanding senior notes of any series with respect to

                                       17
<PAGE>

which a default has occurred and is continuing may waive that default for that
series, other than a default in any payment on any senior note of that series
or a default with respect to a covenant or provision that cannot be amended or
modified without the consent of the holder of each outstanding senior note
affected.

Defeasance and Covenant Defeasance

   The senior indentures provide, unless the terms of the particular series of
senior notes provide otherwise, that:

  . the issuing company may be discharged from its obligations with respect
    to any senior notes or series of senior notes, and, in the case of senior
    notes issued by Mutual Group and guaranteed by MRM, MRM may be discharged
    from its obligations with respect to the related MRM senior note
    guarantee, each of which we refer to as "defeasance;" and/or

  . the issuing company and MRM, as guarantor, if applicable, may be released
    from their obligations under any restrictive covenants described in any
    prospectus supplement or included in any supplemental indenture with
    respect to any senior notes or series of senior notes and the related MRM
    senior note guarantee, which we refer to as "covenant defeasance."

   The senior indentures permit defeasance with respect to any senior notes of
a series even if a prior covenant defeasance has occurred with respect to the
senior notes of that series. Following a defeasance, payment of the senior
notes defeased and the MRM senior note guarantee, if applicable, may not be
accelerated because of an event of default. Following a covenant defeasance,
payment of the senior notes and the MRM senior note guarantee, if applicable,
may not be accelerated by reference to the covenants affected by the covenant
defeasance. However, if an acceleration were to occur, the realizable value at
the acceleration date of the money and government obligations in the defeasance
trust could be less than the amounts then due on the senior notes, since the
required deposit in the defeasance trust would be based upon scheduled cash
flows rather than market value, which would vary depending upon interest rates
and other factors.

   Upon a defeasance, the following rights and obligations will continue: (1)
the rights of the holders of the senior notes of any series to receive from the
defeasance trust any amounts due on the senior notes when payments are due; (2)
the issuing company's obligations regarding the registration, transfer and
exchange of the senior notes of any series; (3) the obligation of the issuing
company and MRM, as guarantor, if applicable, to maintain an office or agency
in each place of payment; and (4) the survival of the senior indenture
trustee's rights, powers, trusts, duties and immunities under the senior
indenture.

   In connection with any defeasance or covenant defeasance, the issuing
company or MRM, as guarantor, if applicable, must irrevocably deposit with the
senior indenture trustee, in trust, money and/or government obligations which,
through the scheduled payment of principal and interest on those obligations,
would provide sufficient moneys to pay all amounts due on the senior notes on
the maturity dates or upon redemption. The issuing company must also deliver to
the trustee an opinion of counsel to the effect that the holders of the senior
notes will not recognize income, gain or loss for United States federal income
tax purposes as a result of the defeasance or covenant defeasance and will be
subject to United States federal income tax on the same amounts, in the same
manner and at the same times as would have been the case if the defeasance or
covenant defeasance had not occurred, and the opinion of counsel, in the case
of defeasance, must refer to and be based upon a letter ruling of the Internal
Revenue Service received by the issuing company, a Revenue Ruling published by
the Internal Revenue Service or a change in applicable United States federal
income tax law occurring after the date of the senior indenture.

Information Concerning the Senior Indenture Trustee

   If an event of default shall occur and be continuing, the senior indenture
trustee shall exercise its rights and powers under the senior indenture in the
same manner and use the same degree of care and skill in its exercise as a
prudent person would exercise or use under the same circumstances in the
conduct of his or her

                                       18
<PAGE>

own affairs. Before proceeding to exercise any right or power under the senior
indenture at the direction of the holders, the senior indenture trustee will be
entitled to receive from the holders reasonable security or indemnity against
the costs, expenses and liabilities that might be incurred by it in complying
with any direction of the holders.

   The Chase Manhattan Bank, which is the senior indenture trustee under each
senior indenture, also serves as the subordinated indenture trustee under each
subordinated indenture described below and as property trustee and guarantee
trustee with respect to the preferred securities issued by each trust. Chase
Manhattan Bank Delaware, an affiliate of The Chase Manhattan Bank, serves as
the Delaware trustee for each trust.

Governing Law

   The senior indentures, the senior notes and the MRM senior note guarantees
will be governed by the laws of the State of New York, without regard to the
conflict of law provisions thereof.

                DESCRIPTION OF THE JUNIOR SUBORDINATED NOTES AND

                THE MRM JUNIOR SUBORDINATED NOTE GUARANTEES

   The junior subordinated notes of MRM will be issued pursuant to a
subordinated indenture, as supplemented from time to time, between MRM and The
Chase Manhattan Bank, as the subordinated indenture trustee. The junior
subordinated notes of Mutual Group will be issued pursuant to a subordinated
indenture, as supplemented from time to time, among Mutual Group, MRM, as
guarantor, and The Chase Manhattan Bank, as subordinated indenture trustee. We
have filed the base subordinated indentures as exhibits to the registration
statement of which this prospectus is a part. You also may request a copy of
the subordinated indentures from the subordinated indenture trustee at its
corporate trust office in New York, New York. Each subordinated indenture will
be qualified under the Trust Indenture Act of 1939. The terms of each series of
junior subordinated notes will include those stated in the applicable
subordinated indenture and those made part of the applicable subordinated
indenture by reference to the Trust Indenture Act.

   MRM and Mutual Group, each referred to as the issuing company, may each
issue series of junior subordinated notes from time to time by entering into
supplemental indentures with the subordinated indenture trustee or pursuant to
resolutions of its board of directors or a duly authorized committee of its
board. Any supplemental indenture or resolutions of either its board of
directors or a duly authorized committee of its board will be executed at the
time the issuing company issues any junior subordinated notes and will be filed
with the SEC on Form 8-K or by a post-effective amendment to the registration
statement of which this prospectus is a part.

General

   The base subordinated indentures do not limit the aggregate principal amount
of junior subordinated notes that the issuing company may issue. The junior
subordinated notes of a series need not be issued at the same time, bear
interest at the same rate or mature on the same date.

   The issuing company will issue the junior subordinated notes under the
applicable subordinated indenture as one or more series of unsecured junior
debt securities. The junior subordinated notes will be unsecured and
subordinated in right of payment to all of the issuing company's existing and
future senior indebtedness and will rank equal in priority with all of the
issuing company's other unsecured and subordinated indebtedness.

   The applicable prospectus supplement and the applicable supplemental
indenture for a particular series of junior subordinated notes will set forth
the following terms of that series:

  . the title of the series;

  . any limit on the aggregate principal amount of the junior subordinated
    notes of the series;

  . the date or dates on which the principal of the junior subordinated notes
    of the series will be payable or the method for determining the date or
    dates;

  . whether the issuing company may shorten or extend the date on which the
    principal of any junior subordinated notes of the series is payable and,
    if so, the terms and conditions of any extension;

  . the rate or rates at which the junior subordinated notes of the series
    will bear interest, if any, or the method for determining the rate or
    rates, and the date or dates from which any interest will accrue;

  . the interest payment dates on which any interest will be payable and the
    regular record date, if any, for any interest payable on any interest
    payment date;

  . whether any of the terms of the applicable subordinated indenture
    described below under "--Option to Extend Interest Payment Date" will not
    apply to the junior subordinated notes of the series;

  . the place or places where payments on the junior subordinated notes of
    the series will be payable, if other than the principal corporate trust
    office of the subordinated indenture trustee;

                                       20
<PAGE>

  . the issuing company's obligation, if any, to redeem or purchase the
    junior subordinated notes of the series pursuant to any sinking fund,
    amortization or analogous provision and the terms and conditions on which
    the junior subordinated notes may be redeemed or purchased pursuant to
    any obligation;

  . the terms and conditions, if any, on which the junior subordinated notes
    of the series may be redeemed at the issuing company's option or at the
    option of the holder;

  . any index or formula for determining the amount of principal or any
    premium or interest on the junior subordinated notes of the series and
    the manner of determining those amounts;

  . the currency, currencies or currency units in which payments on the
    junior subordinated notes of the series will be payable, if other than
    U.S. dollars, and the manner of determining the equivalent of those
    amounts in U.S. dollars for any purpose;

  . if the payments on the junior subordinated notes of the series are
    payable at the issuing company's option or the option of the holders of
    the junior subordinated notes, in one or more currencies or currency
    units other than those in which the junior subordinated notes are stated
    to be payable, the currency, currencies or currency units in which the
    payments on the junior subordinated notes may be payable and the terms
    and conditions of the option;

  . the portion of the principal amount of the junior subordinated notes of
    the series that will be payable upon declaration of acceleration of
    maturity, if other than the entire principal amount;

  . whether any of the terms of the applicable subordinated indenture
    described below under "--Defeasance and Covenant Defeasance" will not
    apply to the junior subordinated notes of the series;

  . whether any of the junior subordinated notes of the series will be
    issuable as global securities and, if so, the depositary and any
    provisions for the transfer or exchange of the global securities, if
    different from those described below under "--Global Securities";

  . any addition to, deletion from or change in events of default or
    covenants with respect to the junior subordinated notes of the series and
    any change in the right of the subordinated indenture trustee or the
    holders of the junior subordinated notes to accelerate the maturity of
    the junior subordinated notes; and

  . any other terms of the junior subordinated notes of the series.

   Unless the applicable prospectus supplement states otherwise, the issuing
company will issue the junior subordinated notes only in fully registered form,
without coupons, and there will be no service charge for any registration of
transfer or exchange of the junior subordinated notes. The issuing company may,
however, require payment to cover any tax or other governmental charge payable
in connection with the registration of transfer or exchange.

   The issuing company may offer and sell the junior subordinated notes at a
substantial discount below their principal amount and the subordinated
indentures do not provide any limit on the amount by which the issuing company
may discount the junior subordinated notes. The applicable prospectus
supplement will describe the special United States federal income tax and other
considerations, if any, applicable to any discounted junior subordinated notes.
In addition, the applicable prospectus supplement may describe certain special
United States federal income tax or other considerations, if any, applicable to
any junior subordinated notes that are denominated in a currency or currency
unit other than U.S. dollars.

   The interest rate and interest and other payment dates of each series of
junior subordinated notes issued to a trust will correspond to those of the
applicable preferred securities of the trust.

MRM Junior Subordinated Note Guarantees

   Unless provided otherwise in a prospectus supplement, MRM will fully and
unconditionally guarantee all obligations with respect to each series of junior
subordinated notes issued by Mutual Group. Unless provided otherwise in a
prospectus supplement, each MRM junior subordinated note guarantee will be
unsecured indebtedness of MRM and will be subordinated in right of payment to
all of MRM's existing and future senior

                                       21
<PAGE>

indebtedness. Each MRM junior subordinated note guarantee will be effectively
subordinated to any secured indebtedness of MRM to the extent of the value of
the assets securing the secured indebtedness. Each MRM junior subordinated note
guarantee will also rank equally with any other MRM junior subordinated note
guarantee of any series of junior subordinated notes issued by Mutual Group. As
a result, in the event of MRM's bankruptcy, liquidation or reorganization or
upon acceleration of any series of junior subordinated notes due to an event of
default, MRM's assets will be available to pay MRM's obligations on an MRM
junior subordinated note guarantee only after all secured and senior
indebtedness of MRM has been paid in full in cash or other payment satisfactory
to the holders of the secured and senior indebtedness of MRM has been made.
There may not be sufficient assets remaining to pay amounts due on any or all
of the MRM junior subordinated note guarantees. Each MRM junior subordinated
note guarantee will also be effectively subordinated to the indebtedness and
other liabilities of MRM's subsidiaries. Each MRM junior subordinated note
guarantee does not prohibit or limit the incurrence of secured or senior
indebtedness or the incurrence of other indebtedness and liabilities by MRM or
its subsidiaries. The incurrence of additional secured and senior indebtedness
and other liabilities by MRM or its subsidiaries could adversely affect MRM's
ability to pay its obligations on an MRM junior subordinated note guarantee.

  Each MRM junior subordinated note guarantee will constitute a guarantee of
payment and not of collection. This means that the holder of the guaranteed
security may sue MRM to enforce its rights under the MRM junior subordinated
note guarantee without first suing any other person or entity.

Additional Amounts

   MRM will make all payments on any series of junior subordinated notes issued
by MRM and all payments under each MRM junior subordinated note guarantee
without withholding or deduction for any taxes, fees, duties, assessments or
governmental charges imposed or levied by Bermuda or any other jurisdiction in
which MRM or any successor is organized or resident for tax purposes or any
political subdivision or taxing authority of Bermuda or any of those other
jurisdictions. If any withholding or deduction is required by law, MRM will pay
to the holder of the junior subordinated notes additional amounts as may be
necessary so that every net payment made to the holder after the withholding or
deduction will not be less than the amount provided for in the applicable
junior subordinated note and the applicable subordinated indenture. MRM will
not be required to pay any additional amounts as a result of:

  . the imposition of any tax, fee, duty, assessment or governmental charge
    that would not have been imposed but for the fact that the holder or
    beneficial owner of the junior subordinated note, other than a trust, was
    a resident or national of or had other specified connections with the
    relevant taxing jurisdiction or presented the junior subordinated note
    for payment in the relevant taxing jurisdiction unless it could not have
    been presented elsewhere;

  . the imposition of any tax, fee, duty, assessment or governmental charge
    that would not have been imposed but for the fact that the holder or
    beneficial owner of the junior subordinated note, other than a trust,
    presented the junior subordinated note for payment more than 30 days
    after it was due and payable;

  . any estate, inheritance, gift, sale, transfer, personal property or
    similar tax, fee, duty, assessment or other governmental charge; or

  . the imposition of any tax, fee, duty, assessment or governmental charge
    that would not have been imposed but for the fact that the holder or
    beneficial owner of the junior subordinated note, other than a trust,
    failed to comply, within 90 days, with any reasonable request by MRM
    addressed to the holder or beneficial owner relating to the provision of
    information or the making of a declaration required by the taxing
    jurisdiction as a precondition to exemption from all or part of the tax,
    fee, duty, assessment or governmental charge.

   In addition, MRM will not be required to pay additional amounts with respect
to any payment to any holder of a junior subordinated note where the beneficial
owner of the junior subordinated note, other than a trust, is a fiduciary or
partnership to the extent that such payment would be required to be included in
the income for tax purposes of a beneficiary with respect to such fiduciary or
a partner of such partnership that would not have been entitled to such
additional amounts if it had been the holder of the junior subordinated note.

Subordination

   Each series of the junior subordinated notes will be unsecured indebtedness
of the issuing company and will be subordinated in right of payment to all of
the issuing company's existing and future senior indebtedness.

                                       22
<PAGE>

The junior subordinated notes will be effectively subordinated to any secured
indebtedness of the issuing company to the extent of the value of the assets
securing the secured indebtedness. As a result, in the event of the issuing
company's bankruptcy, liquidation or reorganization or upon acceleration of the
junior subordinated notes due to an event of default, the issuing company's
assets will be available to pay its obligations on the junior subordinated
notes only after all senior indebtedness has been paid in full in cash or other
payment satisfactory to the holders of the senior indebtedness has been made.
In addition, any assets securing secured indebtedness will be available to pay
the issuing company's obligations under the junior subordinated notes only
after all secured indebtedness has been paid in full in cash or other payment
satisfactory to the holders of the secured indebtedness has been made. There
may not be sufficient assets remaining to pay amounts due on any or all of the
junior subordinated notes then outstanding. The junior subordinated notes will
also be effectively subordinated to the indebtedness and other liabilities of
the issuing company's subsidiaries.

   No payment with respect to the junior subordinated notes of any series may
be made if any senior indebtedness of the issuing company is not paid when due
and any applicable grace period with respect to the default has ended and the
default has not been cured or waived or ceased to exist. If the maturity of any
senior indebtedness has been accelerated because of a default, payments on the
junior subordinated notes may not be made until the accelerated indebtedness
has been paid in full or the acceleration rescinded.

   Except as otherwise provided in the applicable prospectus supplement, the
subordinated indentures do not prohibit or limit the incurrence of secured or
senior indebtedness or the incurrence of other indebtedness and liabilities by
the issuing company or its subsidiaries. The incurrence of additional secured
and senior indebtedness and other liabilities by the issuing company or its
subsidiaries could adversely affect the issuing company's ability to pay its
obligations on the junior subordinated notes.

   The term "senior indebtedness" is defined in each subordinated indenture to
mean, with respect to any issuing company of junior subordinated notes, the
principal of, and any premium and interest on and any other payment in respect
of, indebtedness due pursuant to any of the following, whether outstanding at
the date of execution of each subordinated indenture or incurred after the date
of execution:

  . all indebtedness of the applicable issuing company for money borrowed or
    evidenced by debt securities, acquisition obligations, reimbursement
    obligations, deferred purchase price obligations, capital lease
    obligations and derivative products;

  . all indebtedness of others of the kinds described in the preceding clause
    and all dividends of other persons guaranteed in any manner by the
    applicable issuing company; and

  . all renewals, extensions or refundings of indebtedness of the kinds
    described in either of the preceding clauses;

unless the instrument creating or evidencing the same or pursuant to which the
same is outstanding provides that the indebtedness, renewal, extension or
refunding is not superior in right of payment to or is equal in right of
payment with or subordinated to each series of the junior subordinated notes.
Any senior indebtedness will continue to be senior indebtedness and be entitled
to the benefits of the subordination provisions in each subordinated indenture
irrespective of any amendment, modification or waiver of any term of the senior
indebtedness.

Global Securities

   Some or all of the junior subordinated notes of a series may be represented
in whole or in part by one or more global securities deposited with or on
behalf of one or more depositaries. The applicable prospectus supplement will
describe the terms of any depositary arrangement. Unless the applicable
prospectus supplement states otherwise, the following provisions will apply to
all depositary arrangements for any junior subordinated notes represented by
global securities.

   Each series of the junior subordinated notes that are to be represented by a
global security deposited with or on behalf of a depositary will be represented
by a global security registered in the name of that depositary or its nominee.
Upon the issuance of a global security in registered form, the depositary for
the global security

                                       23
<PAGE>

will credit, on its book-entry registration and transfer system, the respective
principal amount of the applicable junior subordinated notes represented by the
global security to the accounts of institutions that have accounts with the
depositary or its nominee. These institutions are generally brokers, dealers,
banks and other financial institutions, and are referred to as participants.
The accounts to be credited will be designated by the underwriters or agents of
the applicable junior subordinated notes or by the issuing company if the
applicable junior subordinated notes are offered and sold directly by the
issuing company. Ownership of beneficial interests in the global securities
will be limited to participants or persons that may hold interests through
participants. Any person who holds a brokerage account with a participant may
purchase the junior subordinated notes through the participant. Ownership of
beneficial interests by participants in the global securities will be shown on,
and the transfer of any ownership interest will be effected only through,
records maintained by the depositary or its nominee for the global security.
Ownership of beneficial interests in global securities by persons that hold
through participants will be effected only through records maintained by the
applicable participant. Some insurance companies and other institutions are
required by law to hold their investment securities in definitive form, so an
investor may not be able to sell its junior subordinated notes to those
entities.

   So long as the depositary for a global security or its nominee is the
registered owner of the global security, the depositary or nominee, as the case
may be, will be considered the sole owner or holder of the junior subordinated
notes represented by the global security for all purposes under the
subordinated indenture. Except as set forth below, owners of beneficial
interests in the global security will not be entitled to have the junior
subordinated notes represented by the global security registered in their
names, will not receive or be entitled to receive physical delivery of the
junior subordinated notes in definitive form and will not be considered the
owners or holders of the junior subordinated notes under the subordinated
indenture.

   Payments on junior subordinated notes registered in the name of or held by a
depositary or its nominee will be made in immediately available funds to the
depositary or its nominee, as the case may be, as the registered owner or the
holder of the global security representing the junior subordinated notes. None
of the issuing company, MRM, as guarantor, if applicable, the subordinated
indenture trustee, any paying agent or the registrar and transfer agent for the
applicable series of junior subordinated notes will have any responsibility or
liability for any aspect of the records relating to, or payments made on
account of, beneficial ownership interests in a global security for the
applicable series of junior subordinated notes or for maintaining, supervising
or reviewing any records relating to the beneficial ownership interests.

   We expect that a depositary for each series of junior subordinated notes,
upon receipt of any payments in respect of a global security, will immediately
credit participants' accounts with payment in amounts proportionate to their
respective beneficial interests in the principal amount of the global security
as shown on the records of the depositary. We also expect that payments by
participants to owners of beneficial interests in the global security held
through the participants will be governed by standing instructions and
customary practices, as is now the case with securities held for the accounts
of customers registered in "street name," and will be the responsibility of
each participant.

   So long as the depositary for a global security or its nominee is the
registered owner of the global security, the depositary or its nominee, as the
case may be, will be entitled to direct the actions of the subordinated
indenture trustee upon an event of default. However, we expect that a
depositary for each series of the junior subordinated notes upon receiving
notice of an event of default, will immediately solicit the participants
regarding any action to be taken. We also expect that the participants will act
in accordance with standing instructions and customary practices, as is now the
case with securities held for the accounts of customers registered in "street
name," and will, in turn, solicit the owners of the beneficial interests
regarding any action to be taken upon any event of default.

   A global security may not be transferred, in whole or in part, except by the
depositary for the global security to a nominee of the depositary or by a
nominee of the depositary to the depositary or another nominee of the
depositary or by the depositary or any nominee to a successor depositary or a
nominee of the successor

                                       24
<PAGE>


depositary. If a depositary for the junior subordinated notes of a series is at
any time unwilling or unable to continue as depositary and a qualified
successor depositary is not appointed by the applicable issuing company within
90 days or if at any time the depositary ceases to be a clearing agency
registered under the Exchange Act when the depositary is required to be
registered to act as the depositary and no qualified successor is appointed by
the applicable issuing company within 90 days or an event of default has
occurred and is continuing, then the applicable issuing company will issue the
junior subordinated notes in definitive registered form in exchange for the
global security or global securities representing the applicable junior
subordinated notes. In addition, the issuing company may, at any time,
determine not to have any junior subordinated notes represented by one or more
global securities and, in that event, will issue the applicable junior
subordinated notes in definitive registered form in exchange for the global
securities representing the applicable junior subordinated notes. In any of
these instances, an owner of a beneficial interest in a global security will be
entitled to physical delivery in definitive form of the applicable junior
subordinated notes represented by the global security equal in principal amount
to its beneficial interest and to have the applicable junior subordinated notes
registered in its name.

Option to Extend Interest Payment Date

   If provided in the related prospectus supplement, the issuing company will
have the right at any time and from time to time during the term of any series
of junior subordinated notes issued to a trust to defer payment of interest for
the number of consecutive interest payment periods as may be specified in the
related prospectus supplement, subject to the terms, conditions and covenants,
if any, specified in the prospectus supplement. No interest deferral period,
however, may extend beyond the stated maturity of the series of junior
subordinated notes. The United States federal income tax consequences and
special considerations related to a deferral will be described in the related
prospectus supplement.

Events of Default

   The following will be events of default under each subordinated indenture
with respect to each series of junior subordinated notes unless the particular
event of default is not applicable to the particular series of junior
subordinated notes or unless the particular event of default is deleted or
modified in a supplemental indenture as stated in the applicable prospectus
supplement:

  . the issuing company fails to pay principal of or any premium on any
    junior subordinated note of that series, or any additional amounts
    related to principal or premium, on its due date;

  . the issuing company fails to pay any interest on any junior subordinated
    note of that series, or any additional amounts related to interest,
    within 30 days from its due date, after taking into account any permitted
    deferral of interest payments by the issuing company under the terms of
    the junior subordinated notes;

  . the issuing company fails to make any sinking fund payment on its due
    date;

  . the issuing company or, in the case of junior subordinated notes issued
    by Mutual Group and guaranteed by MRM, MRM fails to perform any of its
    covenants in the subordinated indenture, excluding a covenant not
    applicable to the affected series, for 30 days after the subordinated
    indenture trustee or the holders of at least 25% in principal amount of
    the outstanding junior subordinated notes of that series give the issuing
    company and MRM, as guarantor, if applicable, written notice of the
    default and require that the issuing company or MRM, as guarantor, if
    applicable, remedy the breach. However, the 30-day period may be extended
    by either the subordinated indenture trustee or the subordinated
    indenture trustee and the holders of at least the same principal amount
    of junior subordinated notes of that series that had given notice of
    default;

  . the issuing company or MRM, in the case of junior subordinated notes
    issued by Mutual Group and guaranteed by MRM, defaults under any (1)
    indebtedness for any money borrowed, including any other series of debt
    securities, (2) mortgage, indenture or other instrument under which there
    may be issued or

   may be secured or evidenced any indebtedness for money borrowed or (3)
   guarantee of payment for money borrowed, and any default consists of a
   payment default at the stated maturity of the indebtedness, after giving
   effect to any applicable grace period, or results in the indebtedness
   becoming due or being declared due prior to its stated maturity; provided,
   that a default shall exist under this clause only if the aggregate
   principal amount outstanding under all of the indebtedness that is so in
   default or that has become due or been declared due prior to its stated
   maturity, as the case may be, exceeds $40,000,000 and the default has not
   been cured, the indebtedness or accelerated indebtedness has not been
   discharged or the acceleration of the indebtedness has not been rescinded
   or annulled, in each case, within 10 days after the subordinated indenture
   trustee or the holders of at least 25% in principal amount of the junior
   subordinated notes give the issuing company and MRM, as guarantor, if
   applicable, written notice of the default and require that the issuing
   company or MRM, as guarantor, if applicable, remedy the breach;

  . the issuing company or, in the case of junior subordinated notes issued
    by Mutual Group and guaranteed by MRM, MRM fails within 60 days to pay,
    bond or otherwise discharge any uninsured judgment or court order for the
    payment of money in excess of $40,000,000, which is not stayed on appeal
    or is not otherwise being appropriately contested in good faith;

  . the issuing company or, in the case of junior subordinated notes issued
    by Mutual Group and guaranteed by MRM, MRM files for bankruptcy or other
    events of bankruptcy, insolvency or reorganization occur;

  . in the case of junior subordinated notes issued by Mutual Group and
    guaranteed by MRM, the guarantee ceases to be in full force and effect;
    and

  . any other event of default specified in the applicable prospectus
    supplement occurs.

   If the issuing company or, in the case of junior subordinated notes issued
by Mutual Group and guaranteed by MRM, MRM files for bankruptcy or other events
of bankruptcy, insolvency or reorganization occur, all unpaid principal and
accrued interest, premium and additional amounts on the junior subordinated
notes will automatically be immediately due and payable. If any other event of
default with respect to the junior subordinated notes of a series occurs and is
continuing, then the subordinated indenture trustee or the holders of not less
than 25% in principal amount of the outstanding junior subordinated notes of
that series may, by notice to the issuing company, and, in the case of junior
subordinated notes issued by Mutual Group and guaranteed by MRM, MRM and to the
subordinated indenture trustee if given by the holders, declare to be
immediately due and payable all unpaid principal and accrued interest, premium
and additional amounts on all junior subordinated notes of that series.

   At any time after a declaration of acceleration has been made with respect
to the junior subordinated notes of a series and before a judgment or decree
for payment of the money due has been obtained, the holders of not less than a
majority in principal amount of the outstanding junior subordinated notes may
rescind any declaration of acceleration with respect to the junior subordinated
notes and its consequences if:

  . the issuing company or, in the case of junior subordinated notes issued
    by Mutual Group and guaranteed by MRM, MRM deposits with the subordinated
    indenture trustee funds sufficient to pay all overdue principal of and
    any premium, interest and additional amounts on the applicable junior
    subordinated notes, any other amounts due to the subordinated indenture
    trustee and, to the extent that payment of the interest is lawful,
    interest on the overdue interest and additional amounts; and

  . all existing events of default with respect to the applicable junior
    subordinated notes have been cured or waived except non-payment of
    principal on the junior subordinated notes that has become due solely
    because of the acceleration.

   The holders of not less than a majority in principal amount of the
outstanding junior subordinated notes of any series have the right to direct
the time, method and place of conducting any proceedings for any remedy
available to the subordinated indenture trustee or to direct the exercise of
any trust or power conferred on the subordinated indenture trustee with respect
to the junior subordinated notes of that series.

                                       26
<PAGE>

   No holder of a junior subordinated note of any series will have any right to
institute a proceeding with respect to the applicable subordinated indenture or
for any remedy under the applicable subordinated indenture unless:

  . that holder has previously given the subordinated indenture trustee
    written notice that an event of default with respect to the junior
    subordinated notes of that series has occurred and is continuing;

  . the holders of not less than a majority in principal amount of the
    outstanding junior subordinated notes of that series have made written
    request to institute the proceeding;

  . the holder or holders have offered reasonable indemnity to the
    subordinated indenture trustee;

  . the subordinated indenture trustee has failed to institute the proceeding
    for 60 days after receipt of the notice and offer of indemnity; and

  . the subordinated indenture trustee has not received from the holders of
    not less than a majority in principal amount of the outstanding junior
    subordinated notes of that series a direction inconsistent with the
    written request.

   Notwithstanding the foregoing, the holder of any junior subordinated note
will have an absolute and unconditional right to receive payment of the
principal of and any premium, interest and additional amounts on that junior
subordinated note on its maturity date, or, in the case of redemption, the date
of redemption, and to institute suit for the enforcement of any payment against
the issuing company and MRM, as guarantor, if applicable.

Notice of Default

   If an event occurs which is or would become an event of default with respect
to any series of the junior subordinated notes, and the subordinated indenture
trustee knows of the event, the subordinated indenture trustee shall mail to
the holders of the affected junior subordinated notes a notice of the default
within 90 days, unless the default has been cured or waived by the holders of
the affected junior subordinated notes. However, except in the case of a
default in the payment of any amounts due on junior subordinated notes of any
series, the subordinated indenture trustee may withhold the notice if and so
long as the directors and/or responsible officers of the subordinated indenture
trustee determine in good faith that withholding the notice is in the interest
of the holders of the affected junior subordinated notes.

   The issuing company and, in the case of junior subordinated notes issued by
Mutual Group and guaranteed by MRM, MRM are required to furnish annually to the
subordinated indenture trustee an officers' certificate to the effect that, to
the best knowledge of the officers providing the certificate, it is not in
default under the applicable subordinated indenture or, if there has been a
default, specifying the default and its status.

Consolidation, Merger, Conveyance or Transfer

   The Mutual Group subordinated indenture provides that Mutual Group may
consolidate or merge with or into another entity, or convey, transfer or lease
its properties and assets substantially as an entirety to any entity or permit
an entity to convey, transfer or lease its properties and assets substantially
as an entirety to it; provided, that:

  . the successor, if any, is a corporation organized and existing under the
    laws of the United States of America, any State of the United States or
    the District of Columbia and expressly assumes by supplemental indenture
    all of Mutual Group's obligations under the Mutual Group subordinated
    indenture and the related junior subordinated notes;

  . immediately after giving effect to the transaction, no event of default,
    or event which after notice or lapse of time or both would become an
    event of default, will have occurred and be continuing; and

  . Mutual Group delivers an officers' certificate and an opinion of counsel
    to the subordinated indenture trustee, each stating that the transaction
    complies with the Mutual Group subordinated indenture and all conditions
    precedent in the Mutual Group subordinated indenture relating to the
    consolidation, merger, conveyance or transfer have been complied with.

                                       27
<PAGE>

   Upon the assumption by the successor of Mutual Group's obligations under the
subordinated indenture and the junior subordinated notes, the successor will
succeed to and be substituted for Mutual Group under the Mutual Group
subordinated indenture, and Mutual Group will be relieved of all of its
obligations under the Mutual Group subordinated indenture and the related
junior subordinated notes, except as otherwise specified in any applicable
prospectus supplement.

   Each subordinated indenture provides that MRM may consolidate or merge with
or into another entity, or convey, transfer or lease its properties and assets
substantially as an entirety to any entity or permit an entity to convey,
transfer or lease its properties and assets substantially as an entirety to it;
provided, that:

  . the successor, if any, is a corporation organized and existing under the
    laws of the United States of America, any State of the United States, the
    District of Columbia or Bermuda and expressly assumes by supplemental
    indenture all of MRM's obligations under the applicable subordinated
    indenture and the related junior subordinated notes or the MRM junior
    subordinated note guarantees, as the case may be;

  . immediately after giving effect to the transaction, no event of default,
    or event which after notice or lapse of time or both would become an
    event of default, will have occurred and be continuing; and

  . MRM delivers an officers' certificate and an opinion of counsel to the
    subordinated indenture trustee, each stating that the transaction
    complies with the applicable subordinated indenture and all conditions
    precedent in the applicable subordinated indenture relating to the
    consolidation, merger, conveyance or transfer have been complied with.

   Upon the assumption by the successor of MRM's obligations under the
subordinated indenture, the junior subordinated notes and the MRM junior
subordinated note guarantees, if applicable, the successor will succeed to and
be substituted for MRM under the applicable subordinated indenture, and MRM
will be relieved of all of its obligations under the applicable subordinated
indenture, the related junior subordinated notes and the MRM junior
subordinated note guarantees, if applicable, except as otherwise specified in
any applicable prospectus supplement.

Registration and Transfer

   If the junior subordinated notes of a series are to be redeemed, the issuing
company will not be required to:

  . issue, register the transfer of or exchange any junior subordinated notes
    of that series during the 15 days immediately preceding the date notice
    is mailed identifying the junior subordinated notes that are called for
    redemption; or

  . register the transfer of or exchange any junior subordinated note
    selected for redemption, in whole or in part, except for the unredeemed
    portion of any junior subordinated note being redeemed in part.

Denominations

   Each series of the junior subordinated notes will be issuable in
denominations of $1,000 and any integral multiples of $1,000, without coupons,
unless the applicable prospectus supplement states otherwise.

Payment and Paying Agent

   Principal of each series of the junior subordinated notes will be paid only
against surrender of the applicable junior subordinated notes as specified in
the applicable subordinated indenture. Unless the applicable prospectus
supplement states otherwise, interest on each series of the junior subordinated
notes will be payable, at the issuing company's option, (1) by check mailed to
the address of the person entitled to the interest as the address appears in
the security register for the applicable junior subordinated notes or (2) by
wire transfer to an account at a banking institution in the United States that
the person entitled to the interest designates in writing to the subordinated
indenture trustee at least 10 business days prior to the date of payment.

                                       28
<PAGE>

   Unless the applicable prospectus supplement states otherwise, the
subordinated indenture trustee will act as paying agent for each series of the
junior subordinated notes, and the principal corporate trust office of the
subordinated indenture trustee will serve as the office through which the
paying agent acts. The issuing company may designate additional paying agents,
rescind the designation of any paying agents and/or approve a change in the
office through which any paying agent acts.

   All moneys that the issuing company has paid to a paying agent for payment
of principal of or interest on each series of the junior subordinated notes
that remain unclaimed at the end of two years after the principal or interest
has become due and payable will be repaid to the issuing company at its
request. Holders will thereafter look only to the issuing company for any
payments.

Modification of the Subordinated Indenture

   The issuing company, MRM, as guarantor, if applicable, and the subordinated
indenture trustee may amend or modify the subordinated indenture with the
consent of the holders of at least a majority in aggregate principal amount of
the outstanding junior subordinated notes of each series of the junior
subordinated notes affected by the amendment or modification voting as a class.
No amendment or modification may, however, without the consent of the holder of
each outstanding junior subordinated note affected by the amendment or
modification:

  . change the stated maturity of the principal of, or any premium, interest
    or additional amounts on, any junior subordinated note;

  . reduce the amount due and payable upon acceleration of the maturity of
    the junior subordinated note;

  . reduce the principal amount of, the rate of interest on or any premium
    payable upon the redemption of any junior subordinated note, modify the
    calculation of the rate of interest or change the date on which any
    junior subordinated note may be redeemed;

  . change the place of payment or currency of any payment on any junior
    subordinated note;

  . change MRM's obligations to pay any additional amounts;

  . impair the right to institute suit for the enforcement of any payment on
    any junior subordinated note on or after the stated maturity of the
    payment or date of redemption;

  . alter the subordination provisions in a manner that would adversely
    affect the interests of any holder of the junior subordinated notes in
    any material respect;

  . reduce the percentage in principal amount of the junior subordinated
    notes of any series, the consent of whose holders is required to amend or
    modify the subordinated indenture, to waive compliance with specific
    provisions of the subordinated indenture or to waive specific defaults;

  . modify the provisions of the MRM junior subordinated note guarantee; or

  . modify any of the above provisions.

   In addition, the issuing company, MRM, as guarantor, if applicable, and the
subordinated indenture trustee may execute supplemental indentures to:

  . create new series of junior subordinated notes;

  . cure any ambiguity, correct or supplement any provision which may be
    inconsistent with any other provision or make provisions not inconsistent
    with any other provisions with respect to matters on questions arising
    under the applicable subordinated indenture, in each case to the extent
    that the amendment does not adversely affect the interests of any holder
    of the junior subordinated notes in any material respect; and

  . make other changes that do not adversely affect the interests of the
    holders of the junior subordinated notes in any material respect;

as well as for various other purposes.

                                       29
<PAGE>


   In addition, the subordinated indentures may not be amended to alter the
subordination of any junior subordinated notes without the written consent of
each holder of senior indebtedness then outstanding that would be adversely
affected by the alteration.

Waiver of Covenants and Defaults

   The holders of not less than a majority in aggregate principal amount of the
outstanding junior subordinated notes of any series may waive, for that series,
the issuing company's and/or, in the case of junior subordinated notes issued
by Mutual Group and guaranteed by MRM, MRM's compliance with any restrictive
covenants described in any prospectus supplement or included in any
supplemental indenture. The holders of not less than a majority in aggregate
principal amount of the outstanding junior subordinated notes of any series
with respect to which a default has occurred and is continuing may waive that
default for that series, other than a default in any payment on any junior
subordinated note of that series or a default with respect to a covenant or
provision that cannot be amended or modified without the consent of the holder
of each outstanding junior subordinated note affected.

Defeasance and Covenant Defeasance

   The subordinated indentures provide, unless the terms of the particular
series of junior subordinated notes provide otherwise, that:

  . the issuing company may be discharged from its obligations with respect
    to any junior subordinated notes or series of junior subordinated notes
    and, in the case of junior subordinated notes issued by Mutual Group and
    guaranteed by MRM, MRM may be discharged from its obligations with
    respect to the related MRM junior subordinated note guarantee, each of
    which we refer to as "defeasance;" and/or

  . the issuing company and MRM, as guarantor, if applicable, may be released
    from their obligations under any restrictive covenants described in any
    prospectus supplement or included in any supplemental indenture with
    respect to any junior subordinated notes or series of junior subordinated
    notes and the related MRM junior subordinated note guarantee, which we
    refer to as "covenant defeasance."

   The subordinated indentures permit defeasance with respect to any junior
subordinated notes of a series even if a prior covenant defeasance has occurred
with respect to the junior subordinated notes of that series. Following a
defeasance, payment of the junior subordinated notes defeased and the MRM
junior subordinated note guarantee, if applicable, may not be accelerated
because of an event of default. Following a covenant defeasance, payment of the
junior subordinated notes defeased and the MRM junior subordinated note
guarantee, if applicable, may not be accelerated by reference to the covenants
affected by the covenant defeasance. However, if an acceleration were to occur,
the realizable value at the acceleration date of the money and government
obligations in the defeasance trust could be less than the amounts then due on
the junior subordinated notes since the required deposit in the defeasance
trust would be based upon scheduled cash flows rather than market value, which
would vary depending upon interest rates and other factors.

   Upon a defeasance, the following rights and obligations will continue: (1)
the rights of the holders of the junior subordinated notes of any series to
receive from the defeasance trust payments due on the junior subordinated notes
when payments are due, (2) the issuing company's obligations regarding the
registration, transfer and exchange of the junior subordinated notes of any
series, (3) the obligation of the issuing company and MRM, as guarantor, if
applicable, to maintain an office or agency in each place of payment and (4)
the survival of the subordinated indenture trustee's rights, powers, trusts,
duties and immunities under the applicable subordinated indenture.

   In connection with any defeasance or covenant defeasance, the issuing
company or MRM, as guarantor, if applicable, must irrevocably deposit with the
subordinated indenture trustee, in trust, money and/or government obligations
which, through the scheduled payment of principal and interest on those
obligations, would provide sufficient moneys to pay all amount due on the
junior subordinated notes on the maturity dates or upon redemption. The issuing
company must also deliver to the trustee an opinion of counsel to the effect
that the

                                       30
<PAGE>

holders of the junior subordinated notes will not recognize income, gain or
loss for United States federal income tax purposes as a result of the
defeasance or covenant defeasance and will be subject to United States federal
income tax on the same amounts, in the same manner and at the same times as
would have been the case if the defeasance or covenant defeasance had not
occurred, and the opinion of counsel, in the case of defeasance, must refer to
and be based upon a letter ruling of the Internal Revenue Service received by
the issuing company or MRM, as guarantor, a Revenue Ruling published by the
Internal Revenue Service or a change in applicable United States federal income
tax law occurring after the date of the subordinated indenture.

Information Concerning the Subordinated Indenture Trustee

   In case an event of default shall occur and be continuing, the subordinated
indenture trustee shall exercise its rights and powers under the applicable
subordinated indenture in the same manner and use the same degree of care and
skill in its exercise as a prudent person would exercise or use under the same
circumstances in the conduct of his or her own affairs. Before proceeding to
exercise any right or power under the applicable subordinated indenture at the
direction of the holders, the subordinated indenture trustee will be entitled
to receive from the holders reasonable security or indemnity against the costs,
expenses and liabilities that might be incurred by it in complying with any
direction of the holders.

   The Chase Manhattan Bank, which is the subordinated indenture trustee under
each subordinated indenture, also serves as the senior indenture trustee under
each senior indenture described above and as property trustee and guarantee
trustee with respect to the preferred securities issued by each trust. Chase
Manhattan Bank Delaware, an affiliate of The Chase Manhattan Bank, serves as
the Delaware trustee for each trust.

Governing Law

   The subordinated indentures, the junior subordinated notes and the MRM
junior subordinated note guarantees will be governed by the laws of the State
of New York, without regard to the conflict of laws provisions thereof.

                                       31
<PAGE>

                    DESCRIPTION OF THE PREFERRED SECURITIES

   The preferred securities of each trust will be issued pursuant to a trust
agreement for that trust, as subsequently amended and restated, among Mutual
Group, the issuer of the related junior subordinated notes, The Chase Manhattan
Bank, as the property trustee, Chase Manhattan Bank Delaware, as the Delaware
trustee, the three administrative trustees and the holders from time to time of
the applicable trust's preferred and common securities. We have filed the trust
agreements and forms of each amended and restated trust agreement as exhibits
to the registration statement of which this prospectus is a part. You also may
request a copy of the trust agreements from the property trustee at its
corporate trust office in New York, New York. Each trust agreement will be
qualified under the Trust Indenture Act of 1939. The terms of the preferred
securities of a trust will include those stated in the applicable trust
agreement and those made part of the trust agreement by reference to the Trust
Indenture Act. The amended and restated trust agreement for a trust will be
executed at the time the trust issues any preferred securities and will be
filed with the SEC on Form 8-K or by a post-effective amendment to the
registration statement of which this prospectus is a part.

General

   The trust agreement for each trust authorizes the administrative trustees to
issue on behalf of the trust preferred securities that have the terms described
in this prospectus and in the applicable prospectus supplement. The preferred
securities will represent undivided beneficial interests in the assets of the
applicable trust. The proceeds from the sale of each trust's preferred and
common securities will be used by the trust to purchase a series of junior
subordinated notes issued by Mutual Group or MRM, as the case may be. The
junior subordinated notes will be held in trust by the property trustee for the
benefit of the holders of the preferred and common securities of the applicable
trust.

   The terms of the preferred securities of each trust will mirror the terms of
the junior subordinated notes held by the applicable trust. If interest
payments on the junior subordinated notes held by the applicable trust are
deferred as described above, distributions on the preferred securities will
also be deferred. The assets of the trust available for distribution to the
holders of its preferred securities generally will be limited to payments under
the series of junior subordinated notes held by the trust and under the related
MRM junior subordinated note guarantee, if applicable.

   Under the preferred securities guarantee for each trust, the issuing company
will agree to make payments of distributions and payments on redemption or
liquidation with respect to the trust's preferred securities, but only to the
extent the trust has funds available to make those payments and has not made
the payments. If Mutual Group issues junior subordinated notes to a trust, MRM
will also guarantee Mutual Group's obligations under its preferred securities
guarantee. See "Description of the Preferred Securities Guarantees and the MRM
Trust Guarantees." The issuing company's obligations under the applicable
preferred securities guarantee, trust agreement, subordinated indenture and
related junior subordinated notes and, if applicable, MRM's obligations under
the MRM junior subordinated note guarantee and the MRM trust guarantee will
provide a full, irrevocable and unconditional guarantee by MRM of amounts due
on the preferred securities issued by each trust.

   The prospectus supplement relating to the preferred securities of each trust
will describe the specific terms of the preferred securities, including:

  . the name of the preferred securities;

  . the dollar amount and number of preferred securities issued;

  . the annual distribution rate, or method of determining the rate, of
    distributions on the preferred securities, and date or dates from which
    any distributions will accrue;

  . the payment date and the record date used to determine the holders who
    are to receive distributions on the preferred securities;

  . the right, if any, to defer distributions on the preferred securities
    upon extension of the interest payment periods of the related junior
    subordinated notes;

                                       32
<PAGE>

  . the applicable trust's obligation, if any, to redeem or purchase the
    preferred securities and the terms and conditions on which the preferred
    securities may be redeemed or purchased pursuant to any obligation;

  . the terms and conditions, if any, on which the preferred securities may
    be redeemed at the applicable trust's option or at the option of the
    holders;

  . the terms and conditions, if any, upon which the related junior
    subordinated notes may be distributed to holders of the preferred
    securities;

  . the voting rights, if any, of the holders of the preferred securities;

  . whether the preferred securities are to be issued in book-entry form and
    represented by one or more global securities and, if so, the depository
    and any provisions for the transfer or exchange of the global securities,
    if different from those described below under "--Global Securities;" and

  . any other relevant rights, preferences, privileges, limitations or
    restrictions of the preferred securities.

   The prospectus supplement will describe various United States federal income
tax considerations applicable to the purchase, holding and disposition of the
series of preferred securities.

Global Securities

   Some or all of the preferred securities of a series may be represented in
whole or in part by one or more global securities deposited with or on behalf
of one or more depositaries. The applicable prospectus supplement will describe
the terms of any depositary arrangement. Unless the applicable prospectus
supplement states otherwise, the following provisions will apply to all
depositary arrangements for any preferred securities represented by global
securities.

   Preferred securities represented by a global security deposited with or on
behalf of a depositary will be registered in the name of that depositary or its
nominee. Upon the issuance of a global security in registered form, the
depositary for the global security will credit, on its book-entry registration
and transfer system, the respective principal amounts of the preferred
securities represented by the global security to the accounts of institutions
that have accounts with the depositary or its nominee. These institutions are
generally brokers, dealers, banks and other financial institutions and are
often referred to as participants. The accounts to be credited will be
designated by the underwriters or agents of the preferred securities or by the
applicable trust, if the preferred securities are offered and sold directly by
the trust. Ownership of beneficial interests in the global securities will be
limited to participants or persons that may hold interests through
participants. Any person who holds a brokerage account with a participant may
purchase the preferred securities through the participant. Ownership of
beneficial interests by participants in the global securities will be shown on,
and the transfer of any ownership interest will be effected only through,
records maintained by the depositary or its nominee for the global security.
Ownership of beneficial interests in global securities by persons that hold
through participants will be effected only through records maintained by the
applicable participant. Some insurance companies and other institutions are
required by law to hold their investment securities in definitive form, so an
investor may not be able to sell its preferred securities to those entities.

   So long as the depositary for a global security or its nominee is the
registered owner of the global security, the depositary or the nominee, as the
case may be, will be considered the sole owner or holder of the preferred
securities represented by the global security for all purposes under the
applicable trust agreement. Except as set forth below, owners of beneficial
interests in the global security will not be entitled to have the preferred
securities represented by the global security registered in their names, will
not receive or be entitled to receive physical delivery of the preferred
securities in definitive form and will not be considered the owners or holders
of the preferred securities under the applicable trust agreement.

   Payments on preferred securities registered in the name of or held by a
depositary or its nominee will be made in immediately available funds to the
depositary or its nominee, as the case may be, as the registered owner or the
holder of the global security representing the preferred securities. None of
MRM, Mutual Group,

                                       33
<PAGE>

the trusts, the property trustee, the Delaware trustee, any paying agent or the
registrar and transfer agent for the preferred securities will have any
responsibility or liability for any aspect of the records relating to, or
payments made on account of, beneficial ownership interests in a global
security for the preferred securities or for maintaining, supervising or
reviewing any records relating to the beneficial ownership interests.

   We expect that a depositary for the preferred securities of a series, upon
receipt of any payments in respect of a global security, will immediately
credit participants' accounts with payment in amounts proportionate to their
respective beneficial interests in the principal amount of the global security
as shown on the records of the depositary. We also expect that payments by
participants to owners of beneficial interests in the global security held
through the participants will be governed by standing instructions and
customary practices, as is now the case with securities held for the accounts
of customers registered in "street name," and will be the responsibility of
each participant.

   So long as the depositary for a global security or its nominee is the
registered owner of the global security, the depositary or its nominee, as the
case may be, will be entitled to direct the actions of the property trustee
upon an event of default. However, we expect that a depositary for the
preferred securities of a series, upon receiving notice of an event of default,
will immediately solicit the participants regarding any action to be taken. We
also expect that the participants will act in accordance with standing
instructions and customary practices, as is now the case with securities held
for the accounts of customers registered in "street name," and will, in turn,
solicit the owners of the beneficial interests regarding any action to be taken
upon any event of default.

   A global security may not be transferred, in whole or in part, except by the
depositary for the global security, to a nominee of the depositary or by a
nominee of the depositary to the depositary or another nominee of the
depositary or by the depositary or any nominee to a successor depositary or a
nominee of the successor depositary. If a depositary for the preferred
securities of a series is at any time unwilling or unable to continue as
depositary and a qualified successor depositary is not appointed by the
administrative trustees within 90 days or if at any time the depositary ceases
to be a clearing agency registered under the Exchange Act when the depositary
is required to be registered to act as the depositary and no qualified
successor is appointed by the administrative trustees within 90 days or if an
event of default has occurred and is continuing, then the applicable trust will
issue the preferred securities in definitive registered form in exchange for
the global security or global securities representing the preferred securities.
In addition, the administrative trustees may, at any time, determine not to
have any preferred securities represented by one or more global securities and,
in that event, the applicable trust will issue the preferred securities in
definitive registered form in exchange for the global securities representing
the preferred securities. In any of these instances, an owner of a beneficial
interest in a global security will be entitled to physical delivery in
definitive form of the preferred securities represented by the global security
equal in principal amount to its beneficial interest and to have the preferred
securities registered in its name.

Liquidation Distribution Upon Dissolution

   Unless otherwise specified in an applicable prospectus supplement, each
trust agreement will provide that the trust will be dissolved:

  . upon the expiration of the term of the trust;

  . upon the bankruptcy, dissolution or liquidation of Mutual Group or MRM;

  . upon the direction of Mutual Group to the property trustee to dissolve
    the trust and distribute the related junior subordinated notes directly
    to the holders of the preferred and common securities of the trust;

  . upon the redemption of all of the common and preferred securities of the
    trust in connection with the redemption of all of the related junior
    subordinated notes; or

  . upon entry of a court order for the dissolution of the trust.

   Unless otherwise specified in an applicable prospectus supplement, in the
event of a dissolution as described above other than in connection with
redemption, after the trust satisfies all liabilities to its creditors

                                       34
<PAGE>

as provided by applicable law, each holder of the preferred or common
securities of a trust will be entitled to receive:

  . the related junior subordinated notes in an aggregate principal amount
    equal to the aggregate liquidation amount of the preferred or common
    securities held by the holder; or

  . if any distribution of the related junior subordinated notes is
    determined by the property trustee not to be practical, cash equal to the
    aggregate liquidation amount of the preferred or common securities held
    by the holder, plus accumulated and unpaid distributions to the date of
    payment.

   If a trust cannot pay the full amount due on its preferred and common
securities because insufficient assets are available for payment, then the
amounts payable by the trust on its preferred and common securities will be
paid on a pro rata basis. However, if an event of default under the
subordinated indenture has occurred and is continuing with respect to any
related junior subordinated notes, the total amounts due on the preferred
securities of the trust will be paid before any distribution on the common
securities of the trust is made.

Events of Default

   The following will be events of default under each trust agreement:

  . an event of default under the subordinated indenture occurs with respect
    to any related junior subordinated notes;

  . the trust fails to pay any redemption price on any preferred securities
    on its due date;

  . the trust fails to pay any distribution on the preferred securities
    within 30 days from its due date;

  . the trustees fail to perform any of the covenants in the trust agreement,
    other than the covenants in the two prior bullet points, for 30 days
    after the holders of at least 25% of the aggregate liquidation amount of
    the outstanding preferred securities give Mutual Group, the issuing
    company and the trustees written notice of the default and require that
    they remedy the breach. However, the 30-day period may be extended by the
    holders of at least the same aggregate liquidation amount of the
    outstanding preferred securities that had initially given notice of the
    default; or

  . the property trustee files for bankruptcy or other events of bankruptcy,
    insolvency or reorganization occur with respect to the property trustee
    and a successor property trustee is not appointed within 90 days.

   If an event of default with respect to related junior subordinated notes
occurs and is continuing under the applicable subordinated indenture, and the
subordinated indenture trustee or the holders of not less than 25% in principal
amount of the related junior subordinated notes outstanding fail to declare the
unpaid principal of and all other amounts with respect to all of the related
junior subordinated notes to be immediately due and payable, the holders of at
least 25% in aggregate liquidation amount of the outstanding preferred
securities will have the right to declare the unpaid principal of and all other
amounts with respect to the related junior subordinated notes immediately due
and payable by providing notice to Mutual Group, the issuing company, the
property trustee and the subordinated indenture trustee.

   At any time after a declaration of acceleration has been made with respect
to a series of related junior subordinated notes and before a judgment or
decree for payment of the money due has been obtained, the holders of a
majority in aggregate liquidation amount of the preferred securities may
rescind any declaration of acceleration with respect to the related junior
subordinated notes and its consequences:

  . if the issuing company deposits with the trustee funds sufficient to pay
    all overdue principal of and premium, interest and additional amounts on
    the related junior subordinated notes and any other amounts due to the
    subordinated indenture trustee and the property trustee; and

                                       35
<PAGE>

  . if all existing events of default with respect to the related junior
    subordinated notes have been cured or waived except non-payment of
    principal on the related junior subordinated notes that has become due
    solely because of the acceleration.

   The holders of a majority in liquidation amount of the preferred securities
of a trust may waive any past default under the subordinated note indenture
with respect to the related junior subordinated notes, other than a default in
any payment on any related junior subordinated notes or a default with respect
to a covenant or provision that cannot be amended or modified without the
consent of the holder of each outstanding related junior subordinated note
affected. In addition, the holders of at least a majority in liquidation amount
of the preferred securities of a trust may waive any past default under the
trust agreement.

   The holders of a majority in liquidation amount of the preferred securities
of a trust shall have the right to direct the time, method and place of
conducting any proceedings for any remedy available to the property trustee or
to direct the exercise of any trust or power conferred on the property trustee
under the applicable trust agreement.

   A holder of preferred securities of a trust may institute a legal proceeding
directly against the issuing company of the related junior subordinated notes
without first instituting a legal proceeding against the property trustee or
any other person or entity, for enforcement of payment to the holder of the
principal of and any premium, interest or additional amounts on related junior
subordinated notes having a principal amount equal to the aggregate liquidation
amount of the preferred securities of the holder if the issuing company fails
to pay any amounts on the related junior subordinated notes when payable. The
issuing company and the subordinated indenture trustee may not amend or modify
the subordinated indenture to eliminate the preferred securities holders' right
to institute a direct legal action without the consent of the holders of each
outstanding preferred security.

Notice of Default

   If an event occurs which is or would become an event of default with respect
to any preferred securities, and the property trustee knows of the event, the
property trustee shall mail to the holders of the affected preferred securities
a notice of the default within 90 days, unless the default has been cured or
waived by the holders of the affected preferred securities. However, except in
the case of a default in the payment of any amounts due on preferred
securities, the property trustee may withhold the notice if and so long as the
directors and/or responsible officers of the property trustee determine in good
faith that withholding the notice is in the interest of the holders of the
affected preferred securities.

   Mutual Group, the issuing company and the administrative trustees of each
trust are required to furnish annually to the property trustee an officers'
certificate to the effect that, to the best knowledge of the officers providing
the certificate, it is not in default under the applicable trust agreement or,
if there has been a default, specifying the default and its status.

Consolidation, Merger or Amalgamation of the Trust

   None of the trusts may consolidate or merge with or into, or be replaced by
or convey, transfer or lease its properties and assets substantially as an
entirety to any entity, except as described below. A trust may, without the
consent of the holders of the outstanding preferred securities, consolidate or
merge with or into, or be replaced by or convey, transfer or lease its
properties and assets substantially as an entirety to a trust organized under
the laws of any State if:

  . the successor entity either:

    . expressly assumes all of the obligations of the trust relating to its
      preferred securities; or

    . substitutes for the trust's preferred securities other securities
      having substantially the same terms as the preferred securities, so
      long as the substituted successor securities rank the same as the
      preferred securities for distributions and payments upon liquidation,
      redemption and otherwise;

                                       36
<PAGE>

  . a trustee of the successor entity who has substantially the same powers
    and duties as the property trustee of the trust is appointed;

  . the preferred securities are listed or traded, or any substituted
    successor securities will be listed upon notice of issuance, on the same
    national securities exchange or other organization on which the preferred
    securities are then listed or traded;

  . the event does not cause the preferred securities or any substituted
    successor securities to be downgraded by any national rating agency;

  . the event does not adversely affect the rights, preferences and
    privileges of the holders of the preferred securities or any substituted
    successor securities in any material respect;

  . the successor entity has a purpose substantially identical to that of the
    trust;

  . prior to the merger event, Mutual Group has received an opinion of
    counsel from a nationally recognized law firm stating that:

    . the event does not adversely affect the rights, preferences and
      privileges of the holders of the trust's preferred securities or any
      successor securities in any material respect;

    . following the event, neither the trust nor the successor entity will
      be required to register as an investment company under the Investment
      Company Act of 1940; and

    . neither the trust nor the successor entity will be taxable as a
      corporation or classified other than as a grantor trust for United
      States federal income tax purposes; and

  .  Mutual Group or its permitted transferee owns all of the common
     securities of the successor entity and the substituted successor
     securities are guaranteed at least to the extent provided under the
     preferred securities guarantee.

   In addition, unless all of the holders of the preferred securities of a
trust approve otherwise, the trust may not consolidate, amalgamate, merge with
or into, or be replaced by or convey, transfer or lease its properties and
assets substantially as an entirety to any other entity or permit any other
entity to consolidate, amalgamate, merge with or into or replace it if the
transaction would cause the trust or the successor entity to be taxable as a
corporation or classified other than as a grantor trust for United States
federal income tax purposes.

Voting Rights

   Unless otherwise specified in the prospectus supplement, the holders of the
preferred securities of a trust will have no voting rights except as discussed
below and under "--Events of Default," "--Amendment of the Trust Agreement,"
"--Removal and Replacement of Trustees" and "Description of the Preferred
Securities Guarantees and the MRM Trust Guarantees--Amendments and Assignment,"
and as otherwise required by law.

   If any proposed amendment to a trust agreement provides for, or the
administrative trustees of a trust otherwise propose to effect:

  . any action that would adversely affect the powers, preferences or special
    rights of the preferred securities of the trust in any material respect,
    whether by way of amendment to the applicable trust agreement or
    otherwise; or

  . the dissolution, winding-up or termination of the trust other than
    pursuant to the terms of the applicable trust agreement,

then the holders of the preferred securities of the trust as a class will be
entitled to vote on the amendment or proposal. In that case, the amendment or
proposal will be effective only if approved by the holders of at least a
majority in aggregate liquidation amount of the preferred securities of the
trust.

   Without obtaining the prior approval of the holders of at least a majority
in aggregate liquidation amount of the preferred securities of a trust, the
trustees of a trust may not:

  . direct the time, method and place of conducting any proceeding for any
    remedy available to the subordinated indenture trustee for any related
    junior subordinated notes or direct the exercise of any trust or power
    conferred on the property trustee with respect to the preferred
    securities of the trust;

                                       37
<PAGE>

  . waive any default that is waivable under the subordinated indenture with
    respect to any related junior subordinated notes;

  . cancel an acceleration of the principal of any related junior
    subordinated notes; or

  . consent to any amendment, modification or termination of the subordinated
    indenture or any related junior subordinated notes where consent is
    required.

However, if a consent under the subordinated indenture requires the consent of
each affected holder of the related junior subordinated notes, then the
property trustee must obtain the prior consent of each holder of the preferred
securities of the trust. In addition, before taking any of the foregoing
actions, the property trustee shall obtain an opinion of counsel experienced in
such matters to the effect that, as a result of such actions, the trust will
not be taxable as a corporation or classified as other than a grantor trust for
United States federal income tax purposes.

   The property trustee will notify all preferred securities holders of the
trust of any notice of default received from the subordinated indenture trustee
with respect to the junior subordinated notes held by the trust.

   Any required approval of the holders of the preferred securities of a trust
may be given at a meeting of the holders of the preferred securities convened
for the purpose or pursuant to written consent. The property trustee will cause
a notice of any meeting at which holders of securities are entitled to vote to
be given to each holder of record of the preferred securities at the holder's
registered address, or to any other address which has been specified in
writing, at least 15 days and not more than 90 days before the meeting.

   Notwithstanding that the holders of the preferred securities of a trust are
entitled to vote or consent under any of the circumstances described above, any
of the preferred securities that are owned by MRM, Mutual Group, the trustees
of the trust or any affiliate of MRM, Mutual Group or any trustees of the
trust, shall, for purposes of any vote or consent, be treated as if they were
not outstanding.

Amendment of the Trust Agreement

   Each trust agreement may be amended from time to time by Mutual Group, the
issuing company, the property trustee and the administrative trustees of the
trust without the consent of the holders of the preferred securities of the
trust to:

  . cure any ambiguity, correct or supplement any provision which may be
    inconsistent with any other provision or make provisions not inconsistent
    with any other provisions with respect to matters or questions arising
    under the applicable trust agreement,

  . modify, eliminate or add to any provisions to the extent necessary to
    ensure that the trust will not be taxable as a corporation or classified
    as other than a grantor trust for United States federal income tax
    purposes, to ensure that the junior subordinated notes held by the trust
    are treated as indebtedness for United States federal income tax purposes
    or to ensure that the trust will not be required to register as an
    investment company under the Investment Company Act, or

  . to add to the covenants, restrictions or obligations of Mutual Group or
    the issuing company,

in each case to the extent that the amendment does not adversely affect the
interests of any holder of the preferred securities of the trust in any
material respect.

   Other amendments to a trust agreement may be made by Mutual Group, the
issuing company, the property trustee and the administrative trustees of a
trust upon approval of the holders of at least a majority in aggregate
liquidation amount of the outstanding preferred securities of the trust and
receipt by the trustees of an opinion of counsel to the effect that the
amendment will not cause the trust to be taxable as a corporation or classified
as other than a grantor trust for United States federal income tax purposes,
affect the treatment of the junior subordinated notes held by the trust as
indebtedness for United States federal income tax purposes or affect the
trust's exemption from the Investment Company Act.


                                       38
<PAGE>

   Notwithstanding the foregoing, without the consent of each affected holder
of common or preferred securities of a trust, the applicable trust agreement
may not be amended to:

  . change the amount or timing of any distribution on the common or
    preferred securities of the trust or otherwise adversely affect the
    amount of any distribution required to be made in respect of the
    securities as of a specified date;

  . restrict the right of a holder of any securities to institute suit for
    the enforcement of any payment on or after the distribution date; or

  . reduce the percentage of preferred securities required to waive
    compliance with provisions of or defaults under the trust agreement.

   In addition, no amendment may be made to a trust agreement if the amendment
would:

  . cause the applicable trust to be taxable as a corporation or
    characterized as other than a grantor trust for United States federal
    income tax purposes;

  . cause the junior subordinated notes held by the applicable trust to not
    be treated as indebtedness for United States federal income tax purposes;

  . cause the applicable trust to be deemed to be an investment company
    required to be registered under the Investment Company Act; or

  . impose any additional obligation on any trustee of the applicable trust
    without its consent.

Removal and Replacement of Trustees

   The holder of a trust's common securities may remove or replace any of the
administrative trustees and, unless an event of default has occurred and is
continuing under the applicable subordinated indenture, the property trustee
and the Delaware trustee of the trust. If an event of default has occurred and
is continuing under the applicable subordinated indenture, only the holders of
a trust's preferred securities may remove or replace the property trustee and
the Delaware trustee. The resignation or removal of any trustee will be
effective only upon the acceptance of appointment by the successor trustee in
accordance with the provisions of the applicable trust agreement.

Registration and Transfer

   If the preferred securities of a series are to be redeemed, the applicable
trust will not be required to:

  . issue, register the transfer of or exchange any preferred securities of
    that series during the 15 days immediately preceding the date notice is
    mailed identifying the preferred securities that are called for
    redemption; or

  . register the transfer of or exchange any preferred security selected for
    redemption, in whole or in part, except for the unredeemed portion of a
    preferred security being redeemed in part.

Payment and Paying Agent

   Unless the applicable prospectus supplement states otherwise, distributions
on the preferred securities will be payable, at the applicable trust's option,
(1) by check mailed to the address of the person entitled to the distribution
as the address appears in the security register for the preferred securities or
(2) by wire transfer to an account specified by the holder in accordance with
procedures established by the administrative trustees and acceptable to the
paying agent. Payments upon the redemption of the preferred securities will be
paid only against surrender of the preferred securities.

   Unless the applicable prospectus supplement states otherwise, the property
trustee will act as paying agent for the preferred securities, and the
principal corporate trust office of the property trustee will serve as the
office through which the paying agent acts. The applicable trust may designate
additional paying agents, rescind the designation of any paying agents and/or
approve a change in the office through which any paying agent acts.

                                       39

Information Concerning the Property Trustee

   For matters relating to compliance with the Trust Indenture Act, the
property trustee will have all of the duties and responsibilities of an
indenture trustee under the Trust Indenture Act. In case an event of default
shall occur and be continuing, the property trustee must use the same degree of
care and skill as a prudent person would exercise or use in the conduct of his
or her own affairs. Before proceeding to exercise any right or power under any
trust agreement at the direction of the holders of the preferred securities,
the property trustee will be entitled to receive from the holders reasonable
security or indemnity against the costs, expenses and liabilities that it might
incur.

   The Chase Manhattan Bank, which is the property trustee for each trust, also
serves as the senior indenture trustee under each senior indenture, the
subordinated indenture trustee under each subordinated indenture and the
guarantee trustee under each preferred securities guarantee described below.
Chase Manhattan Bank Delaware, an affiliate of The Chase Manhattan Bank, serves
as the Delaware trustee for each trust.

Miscellaneous

   The administrative trustees of each trust are authorized and directed to
conduct the affairs of and to operate the trust in such a way that:

  . it will not be taxable as a corporation or classified as other than a
    grantor trust for United States federal income tax purposes;

  . the junior subordinated notes held by it will be treated as indebtedness
    of the issuing company for United States federal income tax purposes; and

  . it will not be deemed to be an investment company required to be
    registered under the Investment Company Act.

   Mutual Group and the trustees of each trust are authorized to take any
action, so long as it is consistent with applicable law, the applicable
certificate of trust or trust agreement, that Mutual Group and the trustees of
the trust determine to be necessary or desirable for the above purposes.

   Holders of the preferred securities of the trusts have no preemptive or
similar rights.

   None of the trusts may incur indebtedness or place a lien on any of its
assets.

Governing Law

   Each trust agreement and the preferred securities of each trust will be
governed by and construed in accordance with the laws of the State of Delaware,
without regard to the conflict of laws provisions thereof.

                                       40

               DESCRIPTION OF THE PREFERRED SECURITIES GUARANTEES
                          AND THE MRM TRUST GUARANTEES

   MRM's preferred securities guarantee for each trust will be issued pursuant
to a guarantee agreement between MRM and The Chase Manhattan Bank, as the
guarantee trustee. Mutual Group's preferred securities guarantee for each trust
and the related MRM trust guarantee will be issued pursuant to a guarantee
agreement among Mutual Group, MRM and The Chase Manhattan Bank, as the
guarantee trustee. We have filed forms of the guarantee agreements as exhibits
to the registration statement of which this prospectus is a part. You also may
request a copy of the guarantee agreements from the guarantee trustee at its
corporate trust office in New York, New York. Each guarantee agreement will be
qualified under the Trust Indenture Act of 1939. The terms of a preferred
securities guarantee will include those stated in the applicable guarantee
agreement and those made part of the guarantee agreement by reference to the
Trust Indenture Act. A guarantee agreement will be executed at the time any
trust issues any preferred securities and will be filed with the SEC on a Form
8-K or by a post-effective amendment to the registration statement of which
this prospectus is a part.

   Each guarantee agreement will be held by the guarantee trustee for the
benefit of the holders of the preferred securities of the applicable trust.

General

   The issuing company will irrevocably and unconditionally agree to pay in
full to the holders of the preferred securities of each trust the guarantee
payments described below, except to the extent previously paid. The issuing
company will pay the guarantee payments when and as due, regardless of any
defense, right of set-off or counterclaim that the applicable trust may have or
assert. The following payments, to the extent not paid by a trust, will be
covered by the applicable preferred securities guarantee:

  . any accumulated and unpaid distributions required to be paid on the
    preferred securities of the trust, to the extent that the trust has funds
    available to make the payment;

  . the redemption price, including all accumulated and unpaid distributions,
    to the extent that the trust has funds available to make the payment; and

  . upon a voluntary or involuntary dissolution, termination, winding-up or
    liquidation of the trust, other than in connection with a distribution of
    related junior subordinated notes to holders of the preferred securities,
    the lesser of:

   . the aggregate of the liquidation amounts specified in the prospectus
     supplement for each preferred security of the trust plus all
     accumulated and unpaid distributions on the preferred security of the
     trust to the date of payment, to the extent the trust has funds
     available to make the payment; and

   . the amount of assets of the trust remaining available for distribution
     to holders of its preferred securities upon liquidation of the trust.

   The issuing company's obligation to make a guarantee payment with respect to
the preferred securities of a trust may be satisfied by directly paying the
required amounts to the holders of the preferred securities of the trust or by
causing the trust to pay the amounts to the holders.

   Each preferred securities guarantee will be subject to the subordination
provisions described below and will not apply to the payment of distributions
and other payments on the preferred securities of a trust when the trust does
not have sufficient funds legally and immediately available to make the
distributions or other payments.

MRM Trust Guarantee

   Unless provided otherwise in a prospectus supplement, MRM will fully and
unconditionally guarantee all obligations with respect to each preferred
securities guarantee issued by Mutual Group. Unless provided otherwise in a
prospectus supplement, each MRM trust guarantee will be unsecured indebtedness
of MRM and will be subordinated in right of payment to all of MRM's existing
and future senior indebtedness. Each MRM

                                       41
<PAGE>

trust guarantee will be effectively subordinated to any secured indebtedness of
MRM to the extent of the value of the assets securing the secured indebtedness.
Each MRM trust guarantee will also rank equally with any other MRM trust
guarantee of any preferred securities guarantee issued by Mutual Group. As a
result, in the event of MRM's bankruptcy, liquidation or reorganization or upon
an event of default by Mutual Group of its obligations under any of its
preferred securities guarantees, or upon a default by MRM under any of its
trust guarantees, MRM's assets will be available to pay MRM's obligations on an
MRM trust guarantee only after all secured and senior indebtedness of MRM has
been paid in full in cash or other payment satisfactory to the holders of the
secured and senior indebtedness has been made. There may not be sufficient
assets remaining to pay amounts due on any or all of the MRM trust guarantees.
Each MRM trust guarantee will also be effectively subordinated to the
indebtedness and other liabilities of MRM's subsidiaries. Each MRM trust
guarantee does not prohibit or limit the incurrence of secured or senior
indebtedness or the incurrence of other indebtedness and liabilities by MRM or
its subsidiaries. The incurrence of additional secured and senior indebtedness
and other liabilities by MRM or its subsidiaries could adversely affect MRM's
ability to pay its obligations on an MRM trust guarantee.

   Each MRM trust guarantee will constitute a guarantee of payment and not of
collection. This means that the holder of the guaranteed security may sue MRM
to enforce its rights under the MRM trust guarantee without first suing any
other person or entity.

Additional Amounts

   MRM will make all payments under each of its preferred securities guarantees
and all payments under each of its MRM trust guarantees without withholding or
deduction for any taxes, fees, duties, assessments or governmental charges
imposed or levied by Bermuda or any other jurisdiction in which MRM or any
successor is organized or resident for tax purposes or any political
subdivision or taxing authority of Bermuda or any of those other jurisdictions.
If any withholding or deduction is required by law, MRM will pay to the holder
of the preferred securities additional amounts as may be necessary so that
every net payment made to the holder after the withholding or deduction will
not be less than the amount provided for in the applicable preferred securities
guarantee. MRM will not be required to pay any additional amounts as a result
of:

  . the imposition of any tax, fee, duty, assessment or governmental charge
    that would not have been imposed but for the fact that the holder or
    beneficial owner of the preferred securities was a resident or national
    of or had other specified connections with the relevant taxing
    jurisdiction or presented the preferred securities for payment in the
    relevant taxing jurisdiction unless it could not have been presented
    elsewhere;

  . the imposition of any tax, fee, duty, assessment or governmental charge
    that would not have been imposed but for the fact that the holder or
    beneficial owner of the preferred securities presented the preferred
    security for payment more than 30 days after it was due and payable;

  . any estate, inheritance, gift, sale, transfer, personal property or
    similar tax, fee, duty, assessment or other governmental charge; or

  . the imposition of any tax, fee, duty, assessment or governmental charge
    that would not have been imposed but for the fact that the holder or
    beneficial owner of the preferred securities failed to comply, within 90
    days, with any reasonable request by MRM addressed to the holder or
    beneficial owner relating to the provision of information or the making
    of a declaration required by the taxing jurisdiction as a precondition to
    exemption from all or part of the tax, fee, duty, assessment or
    governmental charge.

   In addition, MRM will not be required to pay additional amounts with respect
to any payment to any holder of a preferred security where the beneficial owner
of the preferred security is a fiduciary or partnership to the extent that such
payment would be required to be included in the income for tax purposes of a
beneficiary with respect to such fiduciary or a partner of such partnership
that would not have been entitled to such additional amounts if it had been the
holder of the preferred security.

Subordination

   Each preferred securities guarantee will be unsecured indebtedness of the
issuing company and will be subordinated in right of payment to all of the
issuing company's existing and future senior indebtedness. Each preferred
securities guarantee will be effectively subordinated to any secured
indebtedness of the issuing

                                       42
<PAGE>

company to the extent of the value of the assets securing the secured
indebtedness. Each preferred securities guarantee will also rank equally with
any other preferred securities guarantee issued by the issuing company. As a
result, in the event of the issuing company's bankruptcy, liquidation or
reorganization or upon an event of default under any of its preferred
securities guarantees, the issuing company's assets will be available to pay
its obligations on the preferred securities guarantee only after all secured
and senior indebtedness of the issuing company has been paid in full in cash or
other payment satisfactory to the holders of the secured and senior
indebtedness has been made. There may not be sufficient assets remaining to pay
amounts due on any or all of its preferred securities guarantees. Each
preferred securities guarantee will also be effectively subordinated to the
indebtedness and other liabilities of the issuing company's subsidiaries. The
incurrence of additional secured and senior indebtedness and other liabilities
by the issuing company or its subsidiaries could adversely affect the issuing
company's ability to pay its obligations on the preferred securities
guarantees.

   Each preferred securities guarantee will constitute a guarantee of payment
and not of collection. This means that the holder of the guaranteed security
may sue the issuing company to enforce its rights under the preferred
securities guarantee without first suing any other person or entity.

Amendments and Assignment

   No consent of the holders of the preferred securities of a trust will be
required with respect to any changes to the preferred securities guarantee that
do not adversely affect the rights of the holders of the preferred securities
of the applicable trust in any material respect. Other amendments to the
preferred securities guarantee may be made only with the prior approval of the
holders of at least a majority in aggregate liquidation amount of the preferred
securities of the applicable trust. All guarantees and agreements contained in
the preferred securities guarantee will be binding on the issuing company's
successors, assigns, receivers, trustees and representatives and are for the
benefit of the holders of the preferred securities of the applicable trust.

Events of Default

   An event of default under a preferred securities guarantee occurs if the
issuing company:

  . fails to make any required payments; or

  . fails to perform any of its other obligations under the preferred
    securities guarantee and such failure continues for 30 days.

   The holders of at least a majority in aggregate liquidation amount of the
preferred securities of a trust will have the right to direct the time, method
and place of conducting any proceeding for any remedy available to the
guarantee trustee relating to the preferred securities guarantee of the trust
or to direct the exercise of any trust or power given to the guarantee trustee
under the preferred securities guarantee of the trust.

   If and to the extent that the issuing company does not make payments on the
related junior subordinated notes and, if applicable, MRM does not make
payments on the MRM junior subordinated note guarantee, the trust will not have
funds available to make payments of distributions or other amounts due on its
preferred securities. In those circumstances, a holder of the preferred
securities of the trust will not be able to rely upon the applicable preferred
securities guarantee or the MRM trust guarantee, if applicable, for payment of
these amounts. Instead, the holder may directly sue the issuing company under
the junior subordinated notes or MRM under the MRM junior subordinated note
guarantee, if applicable, to collect its pro rata share of payments owed. If a
holder so sues MRM or Mutual Group to collect payment, then MRM or Mutual
Group, as the case may be, will assume the holder's rights as a holder of
preferred securities under the applicable trust agreement to the extent MRM or
Mutual Group makes a payment to the holder in any legal action.

   The holders of at least a majority in liquidation amount of preferred
securities of a trust may waive any past event of default and its consequences.

Information Concerning Guarantee Trustee

   In case an event of default shall occur and be continuing, the guarantee
trustee must exercise the same degree of care and skill as a prudent person
would exercise or use in the conduct of his or her own affairs. Before
proceeding to exercise any right or power under any guarantee agreement at the
direction of the holders of preferred securities, the guarantee trustee will be
entitled to receive from the holders reasonable security and indemnity against
the costs, expenses and liabilities that it might incur.

   The Chase Manhattan Bank, which is the guarantee trustee, also serves as the
senior indenture trustee under each senior indenture, the subordinated
indenture trustee under each subordinated indenture and the property trustee
for each trust. Chase Manhattan Bank Delaware, an affiliate of The Chase
Manhattan Bank, serves as the Delaware trustee for each trust.

Termination of the Preferred Securities Guarantees and MRM Trust Guarantees

   Each preferred securities guarantee and MRM trust guarantee will terminate
once the preferred securities of the applicable trust are paid in full or
redeemed in full or upon distribution of the related junior subordinated notes
to the holders of the preferred securities of the trust in accordance with the
applicable trust agreement. Each preferred securities guarantee and MRM trust
guarantee will continue to be effective or will be reinstated if at any time
any holder of preferred securities of the applicable trust must restore payment
of any sums paid under the preferred securities, the preferred securities
guarantee or the MRM trust guarantee for the applicable trust.

Governing Law

   Each preferred securities guarantee and MRM trust guarantee will be governed
by and construed in accordance with the laws of the State of New York, without
regard to the conflict of laws provisions thereof.

                  RELATIONSHIP AMONG THE PREFERRED SECURITIES,
                        PREFERRED SECURITIES GUARANTEES
                AND JUNIOR SUBORDINATED NOTES HELD BY THE TRUSTS

   Payments due on the preferred securities of a trust, to the extent the
applicable trust has funds available for the payments, will be guaranteed by
the issuing company and by MRM, if applicable, to the extent described under
"Description of the Preferred Securities Guarantees and the MRM Trust
Guarantees." Payments due on junior subordinated notes issued by Mutual Group
to a trust will be guaranteed by MRM to the extent described under "Description
of the Junior Subordinated Notes and the MRM Junior Subordinated Note
Guarantees." No single document executed by MRM or Mutual Group in connection
with the issuance of the preferred securities of a trust will provide for a
full, irrevocable and unconditional guarantee of the preferred securities of
the trust. It is only the combined operation of the issuing company's
obligations under the applicable preferred securities guarantee, trust
agreement, subordinated indenture and related junior subordinated notes and, if
applicable, MRM's obligations under the MRM junior subordinated note guarantee
and the MRM trust guarantee, that has the effect of providing a full,
irrevocable and unconditional guarantee by MRM of each trust's obligations
under its preferred securities.

   As long as the issuing company makes payments of interest and other payments
when due on the junior subordinated notes held by a trust, the payments will be
sufficient to cover the payment of distributions and redemption and liquidation
payments due on the preferred securities of the trust, primarily because:

  . the aggregate principal amount of the junior subordinated notes held by
    the trust will be equal to the sum of the aggregate liquidation amounts
    of the trust's preferred and common securities;

  . the interest rate and interest and other payment dates on the junior
    subordinated notes held by the trust will match the distribution rate and
    distribution and other payment dates for the trust's preferred
    securities;

  . the issuing company has agreed to pay for any and all costs, expenses and
    liabilities of the trust except the trust's obligations under its
    preferred securities; and

  . the applicable trust agreement provides that the trust will not engage in
    any activity that is inconsistent with the limited purposes of the trust.

                              PLAN OF DISTRIBUTION

   MRM or Mutual Group may sell its senior notes or its junior subordinated
notes and each trust may sell its preferred securities in one or more of the
following ways from time to time:

  . to underwriters for resale to the public or to institutional investors;

  . through agents to the public or to institutional investors; or

  . directly to institutional investors.

   The prospectus supplement for each series of senior notes, junior
subordinated notes or preferred securities will set forth the terms of the
offering of those senior notes, junior subordinated notes or preferred
securities, including the name or names of any underwriters or agents. The
prospectus supplement for each series of senior notes, junior subordinated
notes or preferred securities will also set forth the purchase price of the
senior notes, junior subordinated notes or preferred securities, the proceeds
to MRM, Mutual Group or the applicable trust from the sale, any underwriting
discounts or agency fees and other items constituting underwriters' or agents'
compensation, the initial public offering price, any discounts or concessions
allowed or reallowed or paid to dealers and the securities exchange, if any, on
which the senior notes, junior subordinated notes or preferred securities may
be listed.

   If underwriters participate in the sale, the senior notes, junior
subordinated notes or preferred securities will be acquired by the underwriters
for their own account and may be resold from time to time in one or more
transactions, including negotiated transactions, at a fixed public offering
price or at varying prices determined at the time of sale.

   Unless the applicable prospectus supplement states otherwise, the
obligations of the underwriters to purchase any series of senior notes, junior
subordinated notes or preferred securities will be subject to conditions
precedent and the underwriters will be obligated to purchase all of the series
of senior notes, junior subordinated notes or preferred securities if any are
purchased.

   Underwriters and agents may be entitled under agreements entered into with
MRM, Mutual Group and/or a trust to indemnification against specific civil
liabilities, including liabilities under the Securities Act. Underwriters and
agents may engage in transactions with, or perform services for, us in the
ordinary course of business.

   Each series of senior notes, junior subordinated notes or preferred
securities will be a new issue of securities and will have no established
trading market. Any underwriters to whom the senior notes, junior subordinated
notes or preferred securities are sold for public offering and sale may make a
market in those senior notes, junior subordinated notes or preferred
securities. However, those underwriters will not be obligated to do so and may
discontinue any market making at any time without notice.

                                    EXPERTS

   Ernst & Young, independent auditors, have audited MRM's consolidated
financial statements and schedules included in its Annual Report on Form 10-K,
as amended by its Annual Report on Form 10-K/A, for the year ended December 31,
1999, as set forth in their report, which is incorporated by reference in this
prospectus and registration statement. MRM's financial statements and schedules
are incorporated by reference in reliance on Ernst & Young's report, given on
their authority as experts in accounting and auditing.

                           VALIDITY OF THE SECURITIES

   Richards, Layton & Finger, P.A., Wilmington, Delaware, will pass upon the
validity of the preferred

securities for each trust. Mayer, Brown & Platt, Chicago, Illinois, will pass
upon the validity of the senior notes, the junior subordinated notes and the
preferred securities guarantees for Mutual Group. Conyers Dill & Pearman,

                                       46

Hamilton, Bermuda, will pass upon the validity of the senior notes, the junior
subordinated notes, the MRM senior note guarantee, the MRM junior subordinated
note guarantee, the MRM trust guarantee and the preferred securities guarantee
for MRM. David J. Doyle, an associate with Conyers Dill & Pearman, is a
director of MRM. Debevoise & Plimpton, New York, New York, will pass on certain
legal matters for the agents or underwriters.

                        ENFORCEMENT OF CIVIL LIABILITIES

   MRM is organized under the laws of Bermuda. In addition, some of its
directors and officers, as well as some of the experts named in this
prospectus, reside outside of the United States. A substantial portion of their
assets are located outside of the United States. If may be difficult for you to
effect service of process within the United States upon MRM's directors,
officers and experts who reside outside the United States or to enforce in the
United States judgments of U.S. courts obtained in actions against MRM or its
directors and officers, as well as the experts named in this prospectus, who
reside outside the United States.

   We have been informed by Conyers Dill & Pearman, our legal advisor in
Bermuda, that the United States and Bermuda do not have a treaty providing for
reciprocal recognition and enforcement of judgments in civil and commercial
matters. A final judgment for the payment of money rendered by any federal or
state court in the United States based on civil liability, whether or not
predicted solely upon the federal securities laws, would, therefore, not be
automatically enforceable in Bermuda. A Bermuda court may impose civil
liability on MRM, or its directors or officers who reside in Bermuda, in a suit
brought in The Supreme Court of Bermuda against them with respect to a
violation of federal securities law, provided that the facts surrounding such
violation would constitute or give rise to a cause of action under Bermuda law.
