     Shares of Class A Common Stock, $.01 par value (the "Shares"), are being

The Shares are offered only as part of the insuring transaction and insureds are
not required to pay any consideration for the Shares separate from or in
addition to their insurance premiums.  MMIC is a physician-controlled medical
malpractice insurance company which provides professional liability insurance to
physicians in Minnesota, Iowa, Nebraska, Wisconsin, Illinois, North Dakota and
South Dakota.  Shares accrue daily and are allocated to insureds pursuant to a
formula which considers the insured's underwriting risk classification and
period of coverage with MMIC.  Issuance of Shares to new insureds is subject to
a five-year vesting requirement and all rights will be forfeited if insurance
coverage is not continuous for five years.  See "THE OFFERING."

     The Shares are uncertificated and each shareholder is entitled to only one
vote, regardless of the number of Shares he or she owns.  While MMIHC's Class B
Common Share remains outstanding, its holder, the Minnesota Medical Association,
has the exclusive right to elect directors from persons nominated by MMIHC's
Board of Directors, although the holders of the Class A Common Shares can cause
MMIHC to redeem the Class B Common Share at any time for $1,000, and thereby
terminate this right.

     The Shares are not transferable or assignable and must be redeemed by
MMIHC at net book value, exclusive of any value attributable to MMIC (MMIHC's
principal asset), upon a shareholder's discontinuance of coverage with MMIC for
any reason.  See "DESCRIPTION OF CAPITAL STOCK."

                                  PROSPECTUS SUMMARY


     The following summary is qualified in its entirety by the more detailed
information and the Consolidated Financial Statements and Notes thereto
appearing elsewhere in this Prospectus.

THE COMPANIES

     MMIC originally was organized in 1980 under the auspices of the Minnesota
Medical Association (the "MMA"), to provide professional liability (malpractice)
insurance to Minnesota physicians who are members of the MMA.  At that time,
claims and awards in medical malpractice cases had been increasing dramatically,
and physicians were faced with substantial premium increases and a declining
number of insurers offering medical malpractice coverage.  The business was
reorganized on November 30, 1988 into a stock insurance company (MMIC), wholly
owned by a holding company (MMIHC), which could pursue other business
opportunities.  The reorganization also was effected to give physicians a
limited equity interest in their malpractice insurer while preserving MMIC's
capital and surplus.  As of July 1, 1993, the Iowa physician-owned malpractice
insurer, Iowa Physicians Mutual Insurance Trust ("IPMIT"), was merged with and
into MMIC, and as of June 5, 1996, the Nebraska physician-owned malpractice
insurer, Medical Liability Mutual Insurance Company of Nebraska ("MLM"), was
merged with and into MMIC.  MMIC now provides malpractice insurance to
physicians and physician groups in Minnesota, Iowa, Nebraska, Wisconsin,
Illinois, North Dakota and South Dakota on a claims-made basis.  Professional
liability, general liability, and umbrella excess liability insurance is also
available to hospitals, nursing homes and extended care facilities through MMIC.
MMIC has had the sponsorship of the MMA since inception, and also has the
sponsorship of the Iowa and North Dakota medical associations.  See "BUSINESS."
The address and telephone number of the principal executive offices of MMIHC and
MMIC are as follows:  6600 France Avenue South, Suite 245, Minneapolis,
Minnesota  55435; (612) 922-5445.

THE OFFERING

     Class A Common Shares (the "Shares") are being offered only to insureds of
MMIC as part of the insuring transaction, and insureds are not required to pay
any consideration for the Shares separate from, or in addition to, their
insurance premiums.  Shares accrue daily and are allocated pursuant to a formula
which considers the insured's underwriting risk classification and period of
coverage with MMIC (the "Allocation Formula", which is set forth in the
Appendix).  The number of shares allocated to Nebraska insureds is reduced by a
factor designed to take account of the fact that policy limits, and therefore
premiums, are lower in Nebraska.  Shares allocated to new insureds are not
issued until the end of five years of continuous coverage.  Cessation of
coverage before the completion of five years of coverage will result in a
forfeiture of accrued but unissued shares.  Persons who were insureds at the
time of the 1988 reorganization and persons who were IPMIT or MLM insureds at
the time of the mergers between MMIC,  IPMIT and MLM are not subject to the
five-year vesting requirement.  See "THE OFFERING."


<PAGE>

THE SHARES

     The Shares are uncertificated shares which may be owned by individual
physicians or by individual physicians jointly with the legal entities in which
they practice.  In the latter case, the shares can be voted only by the
physicians.  See "DESCRIPTION OF CAPITAL STOCK."

     Each holder of the Shares is entitled to only one vote, regardless of the
number of Shares held.  The Minnesota Medical Association (the "MMA"), so long
as it holds the single Class B Common Share of MMIHC presently outstanding, has
the exclusive right to vote for the election of directors, but only with respect
to persons nominated for election by a committee of the Board of Directors.  The
holders of the Class A Common Shares, at any time, may cause MMIHC to redeem the
Class B Common Share at par value ($1,000), and thereby gain the right to elect
directors.  Such an action requires the vote of a majority of the Class A
shareholders and two-thirds of the Class A shareholders who vote on the
question.

   
     The Shares are not transferable or assignable, and must be redeemed by
MMIHC at net book value, exclusive of any value attributable to MMIC (MMIHC's
primary asset), upon a shareholder's discontinuance of coverage with MMIC for
any reason.  By excluding the value attributable to MMIC from the calculation of
the redemption amount, MMIC's capital and surplus will be preserved and not
reduced by the redemption.  The redemption amount thus reflects primarily
MMIHC's net income from operations, which consists principally of management
fees paid by MMIC, plus earnings on investments, plus any dividends paid by MMIC
to MMIHC.  In the event of any merger, liquidation, sale of all or substantially
all of the assets, or other extraordinary event, any consideration payable to
holders of the Shares will reflect their full value, and will not be limited to
the redemption amount.  See "DESCRIPTION OF CAPITAL STOCK."  As of December 31,
1997 the net book value of MMIHC (redemption value) was $61.63 per share.
    


                                          2
<PAGE>

                                     THE OFFERING

     Class A Common Shares (the "Shares") are being offered only to insureds of
MMIC who will accrue Shares for each day of insurance coverage they purchase
from MMIC.  Insureds are not required to pay any consideration for the Shares
separate from or in addition to their insurance premiums.  The Shares will be
allocated semi-annually, pursuant to a formula which considers the insured's
underwriting risk classification and period of coverage with MMIC (the
"Allocation Formula", which is set forth in the Appendix).  Shares allocated to
new insureds are not issued until the end of five years of continuous coverage.
Cessation of coverage before the completion of five years of coverage will
result in a forfeiture of accrued but unissued shares.  Persons who were
insureds at the time of the 1988 reorganization and persons who were IPMIT or
MLM insureds at the time of the merger between MMIC, IPMIT and MLM were not
subject to the five-year vesting requirement.  Those persons were issued Shares
upon completion of those transactions and Shares they accrue currently are
deemed issued when they are allocated.

     The Allocation Formula is set forth in the Appendix to the Prospectus.  It
consists of a table which indicates the number of Shares to be accrued by and
allocated to each physician for each year of insurance coverage based upon his
or her insurance risk class.  The insurance risk class each physician is
assigned is based on his or her medical specialty and is the same risk class to
which the physician has been assigned by MMIC for purposes of writing the
professional liability insurance for the physician.  Annual insurance premiums
are based on these risk classes, which are derived from actuarial relativity
statistics.  The number of shares shown in the table therefore reflect, in part,
the relative premiums paid to MMIC by each policyholder.  These relativities
have changed very little since MMIC began its business.  MMIHC reserves the
right to change the Allocation Formula in the future.

     The shares allocable to Nebraska physicians are reduced by a factor to take
account of the fact that policy limits, and therefore premiums, are lower in
Nebraska.  This factor is the inverse of the Increased Limits Factor determined
by MMIC's regular external actuaries to be applicable in order to adjust for the
difference between the policy limit of policies issued in Nebraska as compared
to the base policy limit issued by MMIC in all other states in which it does
business.  MMIC's actuaries have determined that the designated Increased Limits
Factor is currently 1.72.  Therefore, a Nebraska policyholder of MMIC would be
allocated the right to receive 58.1% of the shares of MMIHC Class A Common Stock
otherwise indicated by application of the Allocation Formula.  This is based
upon current information and policy limits, and the actual factor used may be
recalculated from time-to-time.

     The Shares are uncertificated.  Although the Shares have been registered
under the Securities Act of 1933 and state securities laws, they are
nontransferable, and there is no market in which they may be sold.  Upon
discontinuation of a physician's insurance policy with MMIC for any reason, the
Shares must be redeemed by MMIHC.  See "DESCRIPTION OF CAPITAL STOCK."

     No independent brokers, dealers, or underwriters have been engaged to
represent MMIHC in connection with this offering and no commissions will be paid
to any person in connection with offers or sales of the Shares.  The Shares will
be offered and sold solely by officers of MMIHC.

             MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                              AND RESULTS OF OPERATIONS

   
     MANNER OF PRESENTATION.  The financial statements of MMIHC and MMIC are
presented on a consolidated basis.  In future references in this analysis, which
should be read together with the 1997 Consolidated Financial Statements and
Notes thereto appearing elsewhere in this Prospectus, MMIHC and MMIC are
referred to collectively as the "Companies."
    

   
LIQUIDITY AND CAPITAL RESOURCES
    

   
The majority of the Company's assets are invested in bonds, stocks, a
real estate investment trust and short-term instruments. These investments
totaled $245,643,000 and $229,460,000 at December 31, 1997 and 1996,
respectively, which represented 89.2% and 87.5% of total assets. The primary
objective of the Company's investment policy is preservation of assets
while securing the highest return consistent with asset conservation. The
investment in U.S. Government bonds assists in assuring adequate liquidity for
payment of losses. Fixed maturity investments and equity securities are
classified as available for sale and carried at fair value. Through the Third
Quarter of 1997 partially taxable state and other political subdivision bonds
were utilized in the portfolio to reduce federal income taxes.
    

   
During 1997 the Company adopted a revised Investment Policy resulting in
a portfolio restructuring designed to increase overall return from investments.
The benchmark total return goal set for the fixed portfolio manager was
increased. This resulted in a turnover of most of the fixed portfolio which
included selling all municipal bonds. In addition, the Company invested
$10 million in a private placement real estate investment trust to further
diversify the portfolio. This change in policy recognizes the Company's
strong financial position relative to the risk inherent in the amount of premium
written.
    

   
The Company's cash flow from operations has been essentially breakeven
for the years 1996 and 1995 combined. The improved cash flow from 1997
operations to a positive $2,899,000 is primarily the result of lower loss
payments and higher realized capital gains. Premium rates have remained level
for several years causing cash receipts from operations to be relatively level.
In addition, in recent years MMIC has returned substantial amounts of premiums
to policyholders in the form of retrospective premium credits. Loss and
operating expense payments during all three years have generally been met from
current year's premium receipts with any excess cash allocated to the investment
portfolio. The Company regularly analyzes loss liabilities to project
cash flow required in future years. Since  the overall portfolio is highly
liquid, exact matching of bond maturities and liabilities is not a goal.
Maturities are selected to maximize total return. Given the Company's
December 31, 1997 shareholders' equity of $126,290,000, investments of
$245,643,000 and total liabilities of $141,748,000, the Company
anticipates no cash flow problems in the near future.

The Company's bylaws require that MMIHC Class A Common Stock issued to
MMIC policyholders be redeemed when a physician ceases to be insured by MMIC for
any reason. The redemption value per share is calculated by dividing the net
book value of the Company, excluding the net book value of MMIC (other
shareholders' equity) from the calculation, by the number of MMIHC Class A
Common Shares outstanding. More detail about the redeemable stock and the actual
redemptions during the years 1997, 1996 and 1995 are found in Note 2 to the
consolidated financial statements. This limited redemption value preserves the
capital of MMIC as other shareholders' equity. The consolidated statements of
changes in other shareholders' equity found in the accompanying financial
statements provide the details of additions to and reductions in other
shareholders' equity.
    

   
From time to time the Board of Directors of MMIC declares dividends payable to
MMIHC to maintain the redemption value of the Company's Class A Common
Stock. A $260,000 dividend in November 1995 was declared in accordance with that
principle and paid in February of 1996. In July 1996, a dividend of $327,000 was
paid to MMIHC as required by a provision of the MMIC/MLM merger agreement. Per
the merger agreement, the amount was sufficient to maintain the per share
redemption value of MMIHC's Class A Common Stock at the same per share value
immediately after the merger as immediately before the merger. There were no
dividends declared or paid by MMIC to MMIHC in 1997.
    

   
IMPACT OF YEAR 2000
    

   
The Year 2000 Issue is the result of computer programs being written using two
digits rather than four to define the applicable year. Any of the 
Company's computer programs that have time sensitive software may recognize a
date using "00" as the year 1900 rather than the year 2000. This could result in
a system failure or miscalculations causing disruptions of operations,
including, among other things, a temporary inability to process transactions,
send billings, or engage in similar normal business activities.
    

   
Recently, in response to other business issues, the Company decided to
replace all significant application software with new purchased applications. A
key criterion in vendor selection was Year 2000 readiness of the software. The
new applications are currently being installed and are scheduled to be fully
operational prior to December 31, 1998. As a result, management believes that is
has adequately addressed the Year 2000 issue as it relates to internal use
software.
    

   
Management continues to evaluate the Year 2000 readiness of significant vendors
and business partners and will develop contingency plans as deemed necessary.

The current year's provision for loss and loss adjustment expense, which is
based upon policyholder exposure, expected frequency of losses, and severity of
losses, was fairly stable for the years 1997, 1996 and 1995. The loss and loss
adjustment expenses reflected in the consolidated financial statements, and
shown in the Reconciliation of Liability for Loss and Loss Adjustment Expense as
total incurred loss and loss adjustment expense, include adjustments of prior
years' estimates.
    

   
Incurred loss and loss adjustment expenses for 1997 and 1996 of $31,834,000 and
$32,257,000, respectively, are significantly less than the $37,560,000 in 1995.
During the course of each year and particularly at each year end, management
reevaluates the liability for loss and loss adjustment expense. This evaluation
is supported by outside actuarial evaluation at year end. During 1997 and 1996
these evaluations resulted in a reduction is estimated liabilities applicable to
prior years of $8,352,000 and $8,844,000, respectively. A smaller reduction of
$2,287,000 was recorded in 1995. This difference is the primary reason for the
lower incurred loss and loss adjustment expense in 1997 and 1996.
    

   
The schedule which follows summarizes the development of the liability for loss
and loss adjustment expense from 1987 through 1997. This schedule is also
presented net of reinsurance which the Company believes best explains
the development as it affects operating results. The Company has a
conservative loss reserving policy which, when coupled with a moderation of
malpractice insurance losses which began in approximately 1986 for the 
Company and across the industry, has resulted in redundancies in liabilities
larger than expected. The table indicates that the redundancy in loss
liabilities, which developed when more actual results were known, has been
significantly reduced from the high at December 31, 1990. Loss and loss
adjustment expense liabilities have not been discounted in the Company's
financial statements.

RESULTS OF OPERATIONS
    

   
NET PREMIUMS EARNED increased $1,749,000 in 1997 from 1996 while policyholders'
rate levels remained relatively level for 1996 and 1997. An increase in the
number of policyholders in 1997 increased premium by $500,000. The remaining
increase was the result of the several increase/decrease factors listed below:
    

   
1.   The estimated reinsurance premium applicable to the treaty years 1992-1994
     and 1995-1997, which is based in part on reinsured claims experience, was
     reduced resulting in a net increase in premium between years of $3,875,000.
    

   
2.   Company recorded an increase of $1,171,000 in the Iowa Development
     Experience Liability account in 1997. A similar increase of $2,901,000 was
     recorded in 1996. While these increased liabilities both reduce premium,
     the difference in the amounts between years causes an increase in net
     premium from 1996 to 1997 of $1,730,000.
    

   
3.   In 1996 $2,194,000 was received from the commutation of a reinsurance
     treaty covering the years 1989 and 1990. This increased 1996 premiums.
     Since there was no counterpart in 1997 it causes a decrease in premiums
     from 1996 to 1997 of $2,194,000.
    

   
4.   A number of other prior year reinsurance premium adjustments recorded in
     1996 increased 1996 premiums by $2,143,000. With no counterpart in 1997,
     the difference between years is a decrease in 1997 of $2,143,000.
    

   
Investment income has remained relatively level during the last three years.
While invested assets on a cost basis did increase by $6,980,000 during 1997,
almost all of that increase occurred in the last quarter when the fixed
portfolio was restructured to meet a new benchmark return which was referred to
earlier under Liquidity and Capital Resources. Restructuring the fixed portfolio
resulted in realized capital gains of $4,916,000.
    

   
Net premiums earned increased $2,248,000 in 1996 from 1995 while the number of
insured policyholders and rate levels were relatively the same. The primary
reasons for this increase are:
    

   
1.   In 1996, $2,194,000 was received from the commutation of a reinsurance
     treaty covering the years 1989 and 1990. This increases 1996 net premiums.
     There was no similar item in 1995.
    

   
2.   Several other reinsurance treaty adjustments involving prior years
     retrospective reinsurance treaties resulted in reducing 1996 reinsurance
     costs by $1,740,000, thereby increasing net premium earned. The years
     involved ranged from 1987-1995. Most of these treaties originated with
     IPMIT prior to its merger into MMIC on July 1, 1993.
    

   
3.   Offsetting these two major reasons for the increase in 1996 net premiums
     was one significant item which caused a decrease. The Company
     recorded an increase of


                                          13
<PAGE>

     $2,901,000 in an Iowa development experience liability account in 1996. A
     similar increase of $646,000 was recorded in 1995. The difference between
     the 1996 and 1995 amounts decreased net premium $2,255,000. Under terms of
     the MMIC/IPMIT July 1, 1993 merger agreement, if the financial results for
     the years prior to 1993 are more favorable than expected at December 31,
     1992, that favorable development must be returned to the prior IPMIT
     policyholders who renew coverage with MMIC.
    

   
Realized capital gains of $1,771,000 in 1996 and $1,646,000 in 1995 were due to
active management of both the bond and equity sections of the portfolio. During
1997 the Company restructured the fixed portfolio and in this process
experienced realized capital gains of $4,916,000. In addition, normal investment
transactions resulted in additional realized capital gains of $1,568,000 for a
total of $6,484,000. The Company employs two outside professional
advisors to manage the portfolio, one to manage fixed income securities and a
separate manager for equities. The managers operate within the Company's
adopted investment policy. This policy was revised in 1997 as previously
discussed under Liquidity and Capital Resources. The Investment Committee meets
with the outside managers approximately four times per year.
    

   
Other underwriting expenses increased $1,056,000 form 1996 to 1997.
Approximately $425,000 of the increase was due to payments to state medical
societies, for the first time in 1997, under license and endorsement agreements.
The remainder of the increase reflects the increase in overall cost of operating
the Company.
    

   
Income taxes. In 1997 the Company's book net income before taxes was
$13,763,000. Deductions from book income, primarily tax exempt interest income
from municipal bonds reduces income subject to tax. This current year's tax
based on taxable earnings was increased by a reduction in deferred taxes of
$1,494,000 to arrive at the income tax charged to operations $4,463,000 as shown
in the financial statements.
    

   
Deferred tax effects are provided whenever expense items are recorded in the
accompanying financial statements in a time period different from those in the
Company's tax returns.
    

   
Net income for the Company during the last three years totaled
$18,506,000 which was added to retained earnings. A significant portion of net
income for these years resulted from the reversal of loss liabilities
established in prior years and realized capital gains on investments.

                                       BUSINESS

     BACKGROUND.  MMIC originally was organized in 1980 under the auspices of
the MMA to provide professional liability insurance to Minnesota physicians who
are members of the MMA.  At that time, claims and awards in medical malpractice
cases had been increasing dramatically, and physicians were faced with
substantial premium increases and a declining number of insurers offering
medical malpractice coverage.  The business was reorganized in 1988 into a stock
insurance company (MMIC), wholly owned by a holding company (MMIHC) which could
pursue other business opportunities.  The reorganization also was effected to
give physicians a limited equity interest in their malpractice insurer, which
would give them input into the operations of the insurer and an opportunity to
share in any profits, while preserving the capital and surplus of MMIC.  As of
July 1, 1993, the Iowa physician-owned malpractice insurer, IPMIT, was merged
with and into MMIC, and as of June 5, 1996, the Nebraska physician-owned
malpractice insurer, MLM, was merged with and into MMIC.

     MMIC now provides professional liability insurance to physicians in
Minnesota, Iowa, Nebraska, Wisconsin, Illinois, North Dakota and South Dakota.
Professional liability, general liability and umbrella excess liability
insurance is also available to hospitals, nursing homes and extended care
facilities through MMIC.  MMIC has had the sponsorship of the MMA since
inception and also has the sponsorship of the Iowa and North Dakota medical
associations.

     MANAGEMENT AGREEMENT.  Pursuant to a written agreement renewable annually,
MMIC pays MMIHC for comprehensive management, administration, and underwriting
services, and for use of MMIHC's facilities, equipment and personnel.  MMIHC
receives  a management fee generally equal to the allocated cost of providing
such services, plus 10 percent.  As a result of this agreement, MMIHC employs
all of the employees, and owns all of the non-financial assets, used in the
operation of the businesses of the  Companies.  The agreement is subject
to annual review and approval by the Minnesota Department of Insurance.  See
Note 1 to MMIHC's Consolidated Financial Statements.

     INSURANCE POLICIES.  MMIC primarily writes policies of medical professional
liability insurance to:  (1) individual physicians, and (2) partnerships or
professional corporations comprised of physicians ("clinics").  In addition,
MMIC writes business liability insurance providing coverage for claims against a
medical business entity resulting from acts by its employees, and office
premises liability insurance providing coverage for claims arising out of the
ownership, maintenance or use of office premises of the insured.

     In addition to meeting MMIC's underwriting standards, insureds must be
licensed to practice in Minnesota, Iowa, Nebraska, Wisconsin, Illinois, North
Dakota or South Dakota, and conduct a majority of their practice in such states.
All insured clinics must have their principal place of business in one of MMIC's
states and all full-time physicians practicing with insured clinics must be
insured by MMIC.

     MMIC offers a "claims-made" medical malpractice liability insurance policy.
Under a claims-made policy, coverage is provided for claims asserted and
reported to MMIC while the policy is in effect relating to occurrences which
took place during the period in which the insured


                                          15
<PAGE>

had coverage with MMIC.  The policy also covers prior acts (i.e., claims first
made during the policy period with respect to occurrences which took place prior
to the date the insured initially secured coverage from MMIC) for physicians
previously insured under a claims-made policy with another professional
liability insurer.  Prior acts coverage is not available from MMIC for
physicians who have not been continuously insured prior to obtaining coverage
from MMIC.

     MMIC also offers reporting endorsements ("tails") which provide coverage of
subsequent claims (i.e., claims first made subsequent to the date the insured
terminates basic insurance coverage with MMIC, but with respect to occurrences
which took place while the insurance coverage was in effect prior to such
termination date) made against its former insureds who have voluntarily
terminated insurance coverage with MMIC.  In the event of death, permanent
disability, or retirement at age 55 or older after five years of coverage with
MMIC, the reporting endorsement is provided at no additional premium.

     MMIC offers basic limits of coverage from $100,000 for each claim, subject
to $300,000 annual aggregate, up to $5,000,000 for each claim, subject to
$5,000,000 annual aggregate.  Excess coverage above the basic limits is
available from MMIC's reinsurers on a facultative basis.

     REINSURANCE.  MMIC purchases reinsurance in order to reduce its liability
on individual risks and to protect against catastrophic losses.  A reinsurance
transaction takes place when an insurance company transfers, or "cedes", to
another insurer a portion of its exposure on insurance it writes.  The reinsurer
assumes the exposure in return for a portion of the premium.  The reinsurer's
liability is limited to losses it assumes that are in excess of the portion
retained by MMIC.  However, in the event the reinsurer is unable or otherwise
fails to pay, MMIC remains primarily liable for the loss.

     Historically, entering into reinsurance agreements permitted MMIC to issue
policies having greater liability limits than otherwise would have been allowed
under Minnesota insurance law, which prohibits an insurer from retaining a risk
on any one claim that is greater than 10 percent of its surplus.  As MMIC's
surplus has grown, MMIC now utilizes reinsurance primarily to limit its risk on
any single claim.  Such limits of risk assumed by MMIC for physician coverage
have increased from $150,000 in the first year of operations to $750,000
currently.  The single claim limit of risk assumed is $500,000 for hospital
coverage.  The reinsurer will pay losses in excess of the amount of risk
retained by MMIC, not to exceed the limits of liability of the policies issued
by MMIC.

   
     MMIC currently operates under an excess-of-loss reinsurance treaty with
General Reinsurance Corporation of Stanford, Connecticut and Hanover Reinsurance
Company, Hanover, Germany.  General Reinsurance Corporation assumes 85% of the
reinsurance risk under this treaty, and Hanover Reinsurance Company assumes the
remaining 15%.  General Reinsurance Corporation is the largest reinsurer of
medical professional liability in the United States and one of the largest in
the world and has received the highest rating of A++ by A. M. Best & Company,
Inc.  Hanover is one of the largest reinsurers in the world and has been a
leader in medical malpractice insurance.  Its A.M. Best & Company, Inc. rating
is A+.  (See "Rating" for a further description of A. M. Best.)  Coverage under
the treaty was initially issued on October 1, 1986, and is continuous until
cancelled by either party.  MMIC commuted the reinsurance


                                          16
<PAGE>

treaties covering the period from October 1, 1986 through December 31, 1990.  As
a result, there is no longer any reinsurance coverage for those reporting years.
As of December 31, 1997 there are also no open cases or claims pertaining to
those reporting years.  Previous reinsurance treaties, which remain in effect
for pre-1986 incidents, were with various domestic and foreign reinsurers, all
of whom have maintained their obligations to MMIC and appear to be financially
sound.  MMIC currently cedes about $3,500,000 of premium per year under the
reinsurance treaty with General Reinsurance Corporation and Hanover Reinsurance
Company.
    

   
     MARKETING AND DISTRIBUTION.  Marketing of MMIC policies in Minnesota,
South Dakota, Nebraska, Illinois and Wisconsin primarily is handled directly by
MMIC through salaried marketing representatives.  MMIC has also made marketing
arrangements with a select group of large national brokers to assist MMIC in the
production of large accounts and in the production of new coverages as they are
developed.  These brokers will sell MMIC's products in all states in which MMIC
is licensed to do business.  IMS Services Company, a wholly-owned subsidiary of
the Iowa Medical Society, is the exclusive agent for marketing MMIC policies to
physicians and clinics in Iowa.  MMIC does not believe that the loss of any
exclusive agent would have a material adverse effect on its business because
other agents are available and MMIC has the in-house capacity to market directly
in any of these areas.  MMIC hospital insurance policies are marketed directly
by MMIC and through independent agents and brokers.  MMIC approves all policies
(and their terms) sold by agents prior to their becoming effective, and no
commissions are earned by agents until such approval has been granted.
    

     INVESTMENTS.  MMIC's investment portfolio is under the direction of the
Board of Directors acting through the Investment Committee.  The Investment
Committee establishes MMIC's investment policy which, in summary, is to assist
in maintaining MMIC's financial stability through the preservation of assets and
the maximizing of after-tax investment income.  Adequate liquidity is maintained
to ensure that MMIC has the ability to meet its insurance operational
requirements, in particular the payment of claims.  MMIC employs outside
investment managers who manage the portfolio on a discretionary basis consistent
with the policies set by MMIC.  In addition, the Investment Committee utilizes
the services of a separate outside consultant who calculates performance
measures and provides an independent opinion on the overall results being
obtained by the investment managers.

   
     MMIC's investment portfolio consists primarily of fixed income instruments,
including United States government and governmental agency bonds and corporate
bonds.  MMIC's investment policy permits the inclusion of equity securities in
the portfolio in accordance with limitations established by Minnesota law.
Equities comprised 20% of the portfolio on December 31, 1997
    

     The following table sets forth the composition of the combined  investment
portfolio of MMIHC and MMIC at the dates indicated:

     RATING.  A. M. Best & Company, Inc. ("Best's"), publisher of BEST'S
INSURANCE REPORTS, PROPERTY-CASUALTY, has assigned MMIC an A, or excellent,
rating in 1996.  Best's ratings range from A++ to F, and are based on an
analysis of the financial condition and operation of an insurance company as
compared with the industry in general.  MMIHC believes that a favorable rating
has a positive effect since customers and their advisors often review Best's
ratings when selecting an insurer and are more apt to purchase insurance from a
company with a positive rating because of the greater security and stability
associated with a positive rating.  A positive rating relates to the ability of
an insurer to meet its insurance obligations and does not directly relate to the
value of the insurer's securities.  A.M. Best calculates several ratios and
publishes them each year as part of its annual report.

     GOVERNMENT REGULATION.  MMIC is subject to governmental regulation in the
states in which it conducts its business - Minnesota, Iowa, Nebraska, Illinois,
Wisconsin, North Dakota and South Dakota.  Such regulation is conducted by state
agencies having broad administrative power dealing with all aspects of MMIC's
business, including policy terms, rates, dividends and retroactive premium
adjustments to insureds, and dividends to the parent corporation, MMIHC.
Without prior approval from the Minnesota Commissioner of Commerce, annual
dividends to MMIHC cannot exceed 10 percent of unassigned surplus of MMIC or the
prior year's net income from operations of MMIC, whichever is greater.  MMIC is
also subject to statutes that require it to file periodic information with state
regulatory authorities, and is subject to a financial and business conduct
examination every three years.  MMIHC is also subject to statutes governing
insurance holding company systems in Minnesota, which relate primarily to the
acquisition of control of insurance companies directly or through a holding
company.


                                          19

     COMPETITION.  MMIC's major competitor is the St. Paul Companies.  The
St. Paul Companies is a major national property-casualty insurance company, is
the largest writer of medical professional liability insurance in the United
States, and is many times larger than MMIC.  In addition to the St. Paul
Companies, several other national companies have become active in the last
several years, including Medical Protective Insurance Company, CNA Insurance
Company, and the MMI Companies.  At this time these additional competitors have
achieved limited market penetration, but represent an increasing competitive
pressure for the future.  In addition, several other physician-owned specialty
carriers have entered the market, but have yet to be a significant factor in
MMIC's area.  Finally, over the past few years several large self-insured
hospitals in Minneapolis and Des Moines have purchased MMIC insured clinics, and
other physician practices have been purchased by large, self-insured clinics
such as the Mayo Clinic.  Although this trend slowed significantly in 1997.
These trends are causing a contraction in  the market for MMIC's primary
malpractice insurance.   MMIC is the only carrier in Minnesota, Iowa and North
Dakota markets endorsed by local medical societies and owned by its
physician-insureds, which management believes gives MMIC a competitive advantage
in marketing to physicians.
    

   
     The market for medical professional liability insurance is changing,
especially with the dramatic changes proposed and occurring in the broader
health care industry.  Significant changes in the market for medical
professional liability insurance are possible as a result of developments such
as practice consolidation and integration, physician-hospital organizations,
various forms of managed health care, various forms of alliances between
providers, proposals for enterprise liability, and many others.  Management is
developing new programs and products which it believes will allow it to remain
competitive as such change occurs, although no assurance can be given to that
effect.
    

   
     EMPLOYEES.  As of December 31, 1997, MMIHC employed 65 persons, of whom
five were executives, 45 were supervisory employees or specialists, and 15 were
clerical employees.  None of the employees is covered by a collective bargaining
agreement and management believes that relations with employees are good.
    

     PROPERTIES.  MMIHC owns the following fixed assets, all of which are used
in the conduct of its business:

MMIHC and MMIC own no real estate.  MMIHC leases approximately 15,765 square
feet of office space in Edina, Minnesota under a 10-year lease that expires in
2001, subject to the option of MMIHC to renew the lease for an additional five
years after the original term.  An additional 4,060 square feet of office space
is leased in West Des Moines, Iowa under a 10-year lease that expires in 2000,
with an option for MMIHC to extend the term for an additional five years after
the original term.  Finally, 1,249 square feet of office space is leased in
Omaha, Nebraska under a three year lease that expires November 30, 2000.
Aggregate annual rent expense was $427,646  for 1997 and $392,282 for 1996.
Management believes such space will be sufficient for the conduct of its
business for the foreseeable future.
    

     LITIGATION.  MMIC believes that its loss and loss adjustment expense
reserves are adequate to cover possible liability from claims and lawsuits
against its insureds which arise in the normal course of its insurance business.
Apart from such matters, MMIC is not a party to any pending or threatened legal
proceeding which could have a material adverse effect on its operations.

     As of December 31, 1997 the directors of MMIHC, as a group, owned 1,234
Class A Common Shares, or one percent of the total Class A Common Shares
outstanding as of such date.  No executive officer owned any Class A Common
Shares as of such date.
    

   
     All of the directors have been principally engaged in the practice of
medicine for more than five years, except for Dr. Sanders who has been the
Executive Vice President of the MMA since 1990, Michael Abrams, who has been the
Executive Director of the Iowa Medical Society (the "IMS") since 1996 and David
P. Bounk who has been President and CEO of MMIHC since 1991.  Prior to 1996, Mr.
Abrams was Director, Governmental Relations of the Indiana Medical Association
for nine years.
    

     The Bylaws of MMIHC provide that MMIHC's Board of Directors shall include
the following:  (1) up to 20 physicians divided into three classes and elected
for staggered three-year terms; (2) for as long as the Class B Common Share is
outstanding, the Chief Executive Officer of the MMA and the Executive Vice
President of the IMS, both of whom shall be ex-officio directors; (3) the
President of MMIHC as an ex-officio director; and (4) such additional ex-officio
and advisory members as the Board of Directors may determine.  At least
two-thirds of the voting members of the Board of Directors must be members of a
state medical association and insured by MMIC.  The MMA, which has the exclusive
right to elect directors, has agreed to elect the directors nominated by a
committee of the Board of Directors.  Directors serve until their successors are
elected and qualified or until their prior resignation, removal, death or
disqualification.

     The Bylaws of MMIHC provide for the election of directors who are members
of the IMS in a number, when compared to the total number of directors, which is
proportionate to the number of Iowa insureds compared to the total number of
MMIC insureds, subject to a minimum of two Iowa directors, one of whom shall be
the Executive Vice President of the IMS, for as long as the Class B Common Share
is outstanding.  The MMA has placed the Class B Voting Share in a voting trust
which requires the trustee to vote the share for the election of the Iowa
directors nominated by the IMS.

     The Board of Directors of MMIHC has the following standing committees:  (1)
Executive; (2) Audit and Budget; (3) Nomination; and (4) Compensation.  The
activities and current membership of each of these committees are described
below:

     The Executive Committee, pursuant to Minnesota law and the Bylaws of MMIHC,
has the full power and authority to act for the Board between its meetings.  The
members of the Executive Committee include the Chairman, Vice Chairman and
Secretary of the Board of MMIHC, the President, and such other individuals as
appointed by the Board of Directors.  The persons currently on the Executive
Committee are as follows:  Andrew J.K. Smith, Chairman, David P. Bounk, E. Duane
Engstrom, M.D., Roger L. Frerichs, M.D., Richard Geier, M.D., Paul S. Sanders,
M.D., Richard D. Schmidt, M.D., Bruce Trimble, M.D. and Michael Abrams.


                                          23
<PAGE>

     The Audit and Budget Committee reviews and approves the annual audit of the
books and records and annual budget of MMIHC.  The members of the Audit and
Budget Committee are R. Bruce Trimble., Andrew J.K. Smith, M.D., Richard Geier,
M.D., John Balfanz, M.D. and Norman Rinderknecht, M.D.

     The Nominating Committee submits to the Board of Directors the names of all
nominees for election to the Board.  The Chairman of the Board is a member of
the Nominating Committee together with the Vice-Chairman of the Board, the
Chairman of the Board of the MMA or his or her designate, the Chief Executive
Officer of the MMA, and such two members as appointed by the Board.  The members
of the Nominating Committee are Andrew J.K. Smith, M.D., Paul S. Sanders, M.D.,
Michael Abrams, R. Bruce Trimble, M.D., Anthony Jaspers, M.D., and Tim Crimmins,
M.D.

   
     The Compensation Committee reviews and establishes the compensation and
benefits of all executives of MMIHC.  The Committee consists of the Chairman of
the Board, the Vice Chairman of the Board, and two additional members appointed
by the Board.  The current members of the Compensation Committee are Andrew J.K.
Smith, M.D., R. Bruce Trimble, M.D., and James Bishop, M.D. and Charles A. Geer.
    

     The Bylaws of MMIC provide that the directors of MMIHC shall also serve as
the directors of MMIC, with the exception of any outside directors of MMIHC.
Outside directors are persons who are not policyholders of MMIC or members of
the MMA.  There are currently no outside directors of MMIHC so the Boards of
MMIHC and MMIC are identical at this time.

     The Board of Directors of MMIC has the following standing committees:  (1)
Claims (Minnesota and Iowa); (2) Investment; and (3) Underwriting/Risk
Management. The activities and current membership of each of these committees
are described below.

     The Minnesota and Iowa Claims Committees review trial alerts and individual
claims when the settlement authority request is in excess of $350,000.  The
Claims Committees also review periodically all claims and lawsuits that have
been closed and monitors overall claim statistics.  The members of the Minnesota
Claims Committee are Anton S. Nesse, M.D., Theodore S. Olson, M.D., William
Eversmann, Jr., M.D., Mark D. Odland, M.D., Gail Bender, M.D., James R. Bishop,
M.D., William L. Youmans, M.D., Susan J. Cushman, M.D.  The members of the Iowa
Claims Committee are James F. Black, M.D., Norman L. Bone, M.D., Clarence H.
Denser, Jr., M.D., William W. Eversmann, Jr., M.D., Joe F. Fellow, M.D., Kevin
R. Kopesky, M.D., Lance E. Longnecker, M.D., James R. Skinner, M.D.

     The Investment Committee establishes investment policy which is approved by
the Board and implemented by professional investment managers, who are employed
by MMIC for that purpose.  The Investment Committee meets frequently with MMIC's
investment manager and reviews the past performance, the current portfolio and
the future direction of MMIC's investments.  See "Business-Investments."  The
members of the Investment Committee are Richard Geier, Jr., M.D., Chairman,
Charles A. Geer, M.D., Michael Abrams, M.D.,

</TABLE>
    

(1)  Includes employer contributions to qualified retirement plans and the  term
     and cash surrender value of supplemental life insurance premiums.

     The compensation of the President is determined by the Executive Committee.
Pursuant to the Bylaws, the President is a member of the Executive Committee,
but he does not participate in actions on his compensation.  The President
determines the compensation of the other executive officers.

   
     MMIHC also maintains a Supplemental Executive Retirement Plan ("SERP")
which provides an annual retirement benefit for an executive officer who retires
at age 62 with 10 years of service of 70 percent of the officer's final average
salary.  Benefits are reduced for years of service less than 10 and retirement
prior to age 62.  The annual benefit payable under the SERP is reduced by 50
percent of the officer's primary Social Security benefit and by the annual
benefit (expressed in the form of an annuity) of the officer's accrued benefits
under MMIHC's current money purchase pension plan and a predecessor plan.  The
estimated annual benefits payable upon retirement at normal retirement age for
the executive officers in the Summary Compensation table are as follows:  Mr.
Bounk - $149,800; Mr. Bretzman - $90,900; Mr. Kleven - $101,100; Ms. Lincoln -
$58,700 and Mr. Rutz - $92,600.  The estimated annual retirement benefits were
calculated assuming salary increases of six percent per year, discounted four
percent per year for future inflation to express the estimated benefits in
today's dollars.

                             DESCRIPTION OF CAPITAL STOCK

     DESCRIPTION OF CLASS A COMMON SHARES.  Class A Common Shares, $.01 par
value, are uncertificated shares which may be owned by individual physicians or
by individual physicians jointly with the legal entities in which they practice.
In the latter case the Shares can be voted only by the physicians, subject to
their right to grant proxies.  Each individual holder of Class A Common Shares
has only one vote, regardless of the number of shares that he or she owns.
Holders of Class A Common Shares have the right to vote on all corporate matters
except for the election of members of the Board of Directors of MMIHC.  Such
right has been granted to the MMA, the holder of the sole Class B Voting Share
which is authorized and outstanding.  However, the MMA has agreed to elect the
directors nominated by a committee of the Board of Directors.  See "Description
of Class B Voting Share."

     As long as the Class B Voting Share remains outstanding, the holders of
Class A Common Shares may, at any time, cause MMIHC to redeem the Class B Common
Share at par value ($1,000), and thereby gain the right to elect directors.
Such an action requires the vote of a majority of the Class A shareholders and
two-thirds of the Class A shareholders who vote on the question.

     The Class A Common Shares are restricted shares that cannot be sold to any
person other than MMIHC and are subject to mandatory redemption at the time that
the physician-insured terminates his or her insurance coverage for any reason.
The redemption price will be based on the net book value of MMIHC, excluding the
net book value attributable to MMIC (MMIHC's primary asset).  By excluding the
value attributable to MMIC from the calculation of the redemption price, MMIC's
capital and surplus will be preserved and not reduced by the redemption.  Other
terms and conditions of the redemption will be established by the Board of
Directors of MMIHC.  The redemption amount thus reflects primarily MMIHC's net
income from operations, which consists principally of management fees paid by
MMIC, plus earnings on investments, plus any dividends paid by MMIC to MMIHC.

     Holders of Class A Common Shares will share in any remaining assets upon
liquidation of MMIHC, proportionately on the basis of the number of shares held
by each shareholder.  In the event of any liquidation, all of the assets of
MMIHC will be included, including MMIC if MMIC remains a subsidiary of MMIHC at
the time of liquidation.  In the event of any merger, sale of all or
substantially all of the assets, or other extraordinary event, any consideration
payable to holders of Class A Common Shares will reflect the full value of the
Shares and will not be limited to the redemption amount.

     The Class A Common Shares do not entitle their holders to preemptive rights
or cumulative voting, and no assignment or other transfer of the Class A Common
Shares is permitted.  Holders of Class A Common Shares are permitted to enter
into voting agreements and appoint proxies to vote such shares, and are
permitted to assign their rights, if any, to the proceeds from any redemption of
Class A Common Shares.

   
    

     There is no market for the Class A Common Shares, nor is it anticipated
that there ever will be a public or private market in which the Class A Common
Shares are traded.


                                          29
<PAGE>

Accordingly, all holders of Class A Common Shares must expect to retain their
shares until they cease to be policyholders of MMIC.  MMIHC has never paid a
dividend nor does it intend to within the foreseeable future, although the Class
A Common Shares will have the right to receive dividends when, as, and if the
Board of Directors of MMIHC authorizes the payment of a dividend.

     All physicians who were MMIC insureds at the time of the reorganization in
1988, IPMIT insureds at the time of its merger with MMIC in 1993, or MLM
insureds at the time of its merger with MMIC in 1996, received shares of MMIHC
upon completion of those transactions in accordance with the Allocation Formula
set forth in the Appendix, based upon their periods of coverage by MMIC and its
predecessors and their underwriting classifications.  These insureds also accrue
and are issued additional Shares pursuant to the Allocation Formula (reduced by
the inverse of the Increased Limits Factor for Nebraska insureds, see "The
Offering") for each day they remain insured with MMIC after the completion of
those transactions.  Issuance of shares to new insureds of MMIC is subject to a
five-year vesting requirement and all rights will be forfeited if insurance
coverage is not continuous for five years.  The Allocation Formula has been
modified since 1988 and MMIHC reserves the right to modify it in the future.

   
     As of December 31, 19976, there were 121,322 Class A Common Shares
outstanding held by 3,450 physicians; 2,453 additional physicians have accrued
the right to receive 13,041 additional Class A Common Shares subject to
completion of the five-year vesting period.
    

     DESCRIPTION OF CLASS B VOTING SHARE.  The holder of the one Class B Voting
Share authorized by MMIHC's Articles of Incorporation is the MMA.  The Class B
Voting Share has no rights or preferences other than the right to elect the
members of the Board of Directors of MMIHC.  This right gives the MMA the
effective right to elect the Board of Directors of MMIC, since the Bylaws of
both corporations provide that each member of the Board of Directors of MMIC
will be a member of the Board of Directors of MMIHC, and the MMA and MMIHC have
entered into an agreement to exercise their respective voting rights to elect
the same persons to the Board of Directors of MMIHC and MMIC.  A nominating
committee of MMIHC nominates persons to be elected as members of the Board of
Directors, and the MMA has agreed to elect these persons to the Board of
Directors.

     The Class B Voting Share is currently held in a voting trust which
requires the trustee to vote the share for the election of at least two Iowa
directors nominated by the IMS.  See, "MANAGEMENT - Directors."

     As long as the Class B Voting Share remains outstanding, the holders of
Class A Common Shares may, at any time, cause MMIHC to redeem the Class B Common
Share at par value ($1,000) by the vote of a majority of the outstanding Class A
shareholders and two-thirds of the Class A shareholders who vote on the
question.

                            Report of Independent Auditors
    

   
Board of Directors
Midwest Medical Insurance Holding Company
  and Subsidiaries
    

   
We have audited the accompanying consolidated balance sheets of Midwest 
Medical Insurance Holding Company and Subsidiaries as of December 31, 1997 
and 1996, and the related consolidated statements of income, changes in other 
shareholders' equity, and cash flows for each of the three years in the 
period ended December 31, 1997. These financial statements are the 
responsibility of the Company's management. Our responsibility is to express 
an opinion on these financial statements based on our audits. 
    

   
We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
    

   
In our opinion, the financial statements referred to above present fairly, 
in all material respects, the consolidated financial position of Midwest Medical
Insurance Holding Company and Subsidiaries at December 31, 1997 and 1996, and 
the consolidated results of their operations and their cash flows for each of 
the three years in the period ended December 31, 1997, in conformity with 
generally accepted accounting principles.

 Medical Insurance Holding Company and Subsidiaries

Notes to Consolidated Financial Statements

December 31, 1997


   
1. ACCOUNTING POLICIES
    

   
ORGANIZATION AND OPERATIONS
    

   
The Minnesota Medical Insurance Exchange (Exchange) began operations in
October 1980 as a reciprocal or inter-insurance exchange organized under Chapter
71A of the Minnesota Statutes. Minnesota Medical Management, Inc. (MMMI) was the
Exchange's attorney-in-fact and was responsible for management of the Exchange.
    

   
On November 30, 1988, the Exchange was reorganized into a stock insurance
company,  Medical Insurance Company (MMIC), under the statutes of the
State of Minnesota. Concurrently, MMMI merged with the  Medical Insurance
Holding Company (MMIHC) which then acquired all outstanding shares of the
reorganized stock company.
    

   
Effective July 1, 1993, MMIC merged with Iowa Physicians Mutual Insurance Trust
(IPMIT), a physician-owned professional liability insurance company providing
insurance coverage to Iowa physicians. As provided for in the agreement and plan
of merger, IPMIT was merged into MMIC. The merger was accounted for as a
pooling-of-interests.
    

   
During 1995, MMIHC formed MMIHC Services, Inc. to provide agency services for
the distribution of complementary insurance products and services to physicians,
clinics and hospitals.
    

   
Effective June 5, 1996, MMIC merged with Medical Liability Mutual Insurance
Company of Nebraska (MLM), a physician-owned professional liability insurance
company providing insurance coverage to Nebraska physicians. As provided for in
the agreement and plan of merger, MLM was merged into MMIC. The merger was
accounted for as a pooling-of-interests and, accordingly, the consolidated
financial statements include the combined financial position and results of
operations of MMIHC and MLM for all periods presented.

1. ACCOUNTING POLICIES (CONTINUED)
    

   
MMIHC provides management and administrative services to MMIC for a fee
generally equal to the cost of services provided plus ten percent. The insurance
company provides professional liability insurance to physicians in Minnesota,
Iowa, Nebraska, North Dakota and South Dakota.
    

   
Insurance policies issued by MMIC are on a "claims made" basis and provide
coverage for the policyholder for claims first made against the policyholder and
reported to MMIC during the policy period for claims which occurred on or after
the retroactive date stated in the policy.
    

   
MMIC provides, upon payment of an additional premium, a reporting endorsement
which extends the period in which claims otherwise covered by the "claims made"
policy may be reported to MMIC. In the event of death or permanent disability of
a policyholder, the reporting endorsement is issued without additional premium.
Upon retirement, as defined in the policy, a policyholder with at least five
years of consecutive coverage with MMIC is eligible for a credit toward the
additional premium for the reporting endorsement.
    

   
Prior acts coverage may be purchased by policyholders who were previously
insured under a "claims made" policy with another professional liability insurer
for an additional premium at the option of the insured in lieu of purchasing
reporting endorsement coverage from the previous insurer.
    

   
PRINCIPLES OF CONSOLIDATION
    

   
The consolidated financial statements include the accounts of MMIHC and its
wholly-owned subsidiaries, MMIC and MMIHC Services, Inc. All transactions
between MMIHC and its subsidiaries have been eliminated in consolidation with
the exception of the distribution of capital to MMIHC by MMIC in the form of
dividends.
    

   
Hereafter, MMIHC, MMIC and MMIHC Services, Inc. shall be collectively referred
to as the Company unless the reference pertains to a specific entity.

1. ACCOUNTING POLICIES (CONTINUED)
    

   
BASIS OF PRESENTATION
    

   
The consolidated financial statements have been presented in conformity with
generally accepted accounting principles, which differ in certain respects from
statutory accounting practices followed by MMIC in reporting to the Department
of Commerce of the State of Minnesota (see Note 10).
    

   
USE OF ESTIMATES
    

   
The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets, liabilities, revenues and expenses, as
well as disclosure of contingent assets and liabilities at the date of the
financial statements. Actual results could differ from those estimates.
    

   
INVESTMENTS
    

   
The Company manages its investment portfolio to achieve its long-term investment
objective of providing for the financial stability of the Company through
preservation of assets and maximization of total portfolio return. Although
management believes the Company has the ability to hold its fixed maturity
investment portfolio to maturity, these investments are classified as "available
for sale" as management may take advantage of opportunities to increase total
return through sales of selected securities in response to changing market
conditions.
    

   
Consistent with management's classification of its investment in debt and equity
securities as available for sale, such investments are carried at fair value
with unrealized holding gains and losses reflected as a separate component of
equity, net of applicable deferred taxes.
    

   
Fair values are based on quoted market prices, where available. For fixed
maturity investments not actively traded, fair values are estimated using values
obtained from independent pricing services.

Notes to Consolidated Financial Statements (continued)


   
1. ACCOUNTING POLICIES (CONTINUED)
    

   
Short-term investments are principally money market funds backed by U.S.
government securities and are recorded at cost which approximates fair value.
    

   
Other investments are equity interests in non-traded real estate investment
trusts and are recorded at cost which approximates fair value.
    

   
Realized gains and losses on sales of investments are reported on a pre-tax
basis as a component of income and are determined on the specific identification
basis.
    

   
LOSSES AND LOSS ADJUSTMENT EXPENSES
    

   
The liability for unpaid losses and loss adjustment expenses represents an
estimate of the ultimate cost of all such amounts which are unpaid at the
balance sheet dates. The liability is based on both case-by-case estimates and
statistical analysis and projections using the historical loss experience of
MMIC, and gives effect to estimates of trends in claim severity and frequency.
These estimates are continually reviewed and, as adjustments become necessary,
such adjustments are included in current operations. MMIC believes that the
estimate of the liability for losses and loss adjustment expenses is reasonable.
    

   
PREMIUMS
    

   
Premiums received are recorded as earned ratably over the lives of the policies
to which they apply. A portion of premiums received is deferred to recognize
MMIC's obligation to provide reporting endorsement coverage without additional
premium upon the death, disability or retirement of policyholders. This amount
is recorded as an unearned premium reserve and represents the actuarially
determined present value of future benefits to be provided less the present
value of future revenues to be received.
    

   
MMIC has a retro premium program whereby physicians may receive credits against
future premiums based upon loss experience of MMIC. Amounts to be returned under
the program are accrued when approved by the Board of Directors and reflected as
a reduction in net premium earned.

1. ACCOUNTING POLICIES (CONTINUED)
    

   
REINSURANCE
    

   
MMIC cedes reinsurance in order to reduce its liability on individual risks and
to enable it to write business at limits it otherwise would be unable to accept.
All reinsurance contracts are excess-of-loss contracts which indemnify MMIC for
losses in excess of a stated retention limit up to the policy limits.
    

   
Reinsurance receivables and recoverables and prepaid reinsurance premiums are
reported as assets and reserve liabilities are reported gross of reinsurance
credits.
    

   
UNDERWRITING EXPENSES
    

   
Underwriting costs are expensed when incurred. Due to the nature of its
operations, MMIC does not pay significant amounts in commissions.
    

   
INCOME TAXES
    

   
The Company uses the asset and liability method of accounting for income taxes.
Deferred income tax assets or liabilities are recognized for the temporary
differences between the carrying amounts of assets and liabilities for financial
reporting purposes and amounts used for income tax purposes.
    

   
EARNINGS PER SHARE
    

   
In 1997, the Financial Accounting Standards Board issued Statement No. 128,
EARNINGS PER SHARE. Statement 128 replaced the calculation of primary and fully
diluted earnings per share with basic and diluted earnings per share. Unlike
primary earnings per share, basic earnings per share excludes any dilutive
effects of all earned but unissued shares of Class A common stock (see Note 2).
Diluted earnings per share is very similar to the previously reported fully
diluted earnings per share. All earnings per share amounts for all periods have
been presented and, where appropriate, restated to conform to the Statement 128
requirements.

RECLASSIFICATIONS

Certain amounts in the prior years' financial statements have been reclassified
to conform with the current year presentation.

2. REDEEMABLE STOCK

Effective November 30, 1988, MMIC policyholders earn Class A Common Shares for
each month of service pursuant to a stock allocation formula based on
underwriting risk classification. Shares earned by new policyholders are not
issued until the end of five years of continuous coverage under an MMIC policy
(the vesting date). The Company does not record any amounts related to unissued
Class A Common Shares. At the vesting date, the issued shares are recorded at
the then current redemption value (see Note 12).

The Company accounts for these shares by increasing Common Stock by the par
value ($.01 per share) of the newly issued shares, increasing paid-in capital by
the excess of the redemption value over par and charging stock compensation
expense for the full redemption value. Once vested, policyholders will continue
to earn shares for each month they remain insured with MMIC according to the
stock allocation formula. The Company accounts for additional shares issued to
vested policyholders by increasing Common Stock for the par value of the shares
and decreasing retained earnings by the same amount.

MMIC policyholders whose initial effective date was on or before the November
30, 1988 reorganization, IPMIT policyholders whose initial effective date was on
or before December 31, 1992 and MLM policyholders whose initial effective date
was on or before December 31, 1995 became fully vested upon initial receipt of
their shares without regard to their length of coverage. These policyholders
will continue to earn and receive additional Class A shares for each month they
remain insured with MMIC. The Company accounts for these shares similar to
additional shares issued to other fully vested shareholders.

2. REDEEMABLE STOCK (CONTINUED)
    

   
In accordance with the Articles of Incorporation and By-laws of MMIHC, only
active policyholders of MMIC may own shares of Class A Common Stock of MMIHC. At
each meeting of the shareholders, every Class A shareholder having the right to
vote shall be entitled to one vote, either in person or by proxy, regardless of
the number of Class A shares held by the individual.
    

   
Class A shareholders are required to redeem their shares with MMIHC upon
termination as policyholders of MMIC. The net redemption value (NRV) of the
shares is equal to the net book value of MMIHC, excluding the amount of net book
value that is attributable to MMIC, divided by the number of outstanding Class A
Common Shares of MMIHC at the semi-annual valuation dates of June 30 and
December 31 of each year. The amount paid upon redemption is the redemption
value determined at the most recent semi-annual valuation.
    

   
MMIHC has issued one share of Class B voting stock which carries with it the
right to elect the Board of Directors of MMIHC. The voting rights are currently
exercised by the Minnesota Medical Association and the Iowa Medical Society. A
majority of the Class A shareholders may at any time, by a two-thirds vote,
elect to redeem the Class B share at cost.

A provision of the agreement and plan of merger between IPMIT and the Company
requires that any favorable development of certain pre-merger liabilities of
IPMIT be paid to the former IPMIT policyholders who remain active MMIC insureds
as of the date of payment through a retrospective premium credit. The agreement
further stipulates that any amounts due under this provision must be settled no
later than December 31, 1998. Actual payments of $2,501,000 and $2,330,000 were
made to former IPMIT policyholders in 1997 and 1996, respectively. Actual
retrospective premium credits applied to Minnesota policyholder accounts in 1997
and 1996 were $4,803,000 and $5,198,000, respectively.
    

   
A provision of the agreement and plan of merger between MLM and the Company
requires that any favorable development of certain pre-merger liabilities of MLM
be paid to the former MLM policyholders who remain active MMIC insureds as of

Management has determined that no valuation allowances were necessary for
unrealizable portions of deferred tax assets. This was supported primarily
through the presence of taxable income in carryback years and reversals of
existing temporary differences which provide taxable income in future years. A
portion of the deferred tax assets was supported through reliance on available
tax planning strategies which could be implemented at no cost.
    

   
7. REINSURANCE
    

   
To reduce overall risk, including exposure to large losses, the Company
participates in various reinsurance programs. MMIC would only become liable for
losses in excess of stipulated amounts in the event that any reinsuring company
were unable to meet its obligations under the existing agreement. Management is
not aware of any such default at

7. REINSURANCE (CONTINUED)
    
   
December 31, 1997. Reinsurance recoverables on paid and unpaid losses of
$16,141,000 and $17,485,000 are associated with a single reinsurer at December
31, 1997 and 1996, respectively.
    

   
MMIC is authorized to issue policies with limits not to exceed $5,000,000 for
each claim and $5,000,000 in the aggregate under each policy in any one policy
year. Limits in excess of $5,000,000 for each claim and $5,000,000 annual
aggregate are available to physicians and clinics through reinsurance placed on
a facultative basis by MMIC. The Company generally retains the first $750,000 of
each claim and reinsures the remainder through a treaty under which premiums are
subject to adjustment based on experience.
    

   
Total ceded reinsurance premiums, before the effects of treaty commutations, for
the years ended December 31, 1997, 1996 and 1995 were $3,329,000, $6,416,000 and
$7,544,000, respectively. Loss and loss adjustment expenses incurred are net of
applicable reinsurance of $2,455,000, $2,459,000 and $7,873,000 for the years
ended December 31, 1997, 1996 and 1995, respectively.
    

   
In 1996, the Company commuted reinsurance treaties covering the period January
1, 1989 through December 31, 1990. Net premiums recovered as a result of these
commutations of $2,194,000 have been included in net premiums earned in 1996.
    

   
8. OTHER COMMITMENTS
    

   
In the normal course of claim settlement, MMIC negotiates structured settlements
including the purchase of annuities from life insurance companies with an A+
rating from A.M. Best (an industry rating organization) at the date of issue and
a minimum of $100 million in surplus. These annuities guarantee a stream of
payments to the claimant holding the annuity. The majority of these settlements
have been assigned to the life insurance company which releases MMIC from any
future contractual liability to the claimant. MMIC and its reinsurers could only
become liable for ultimate settlement of those claims which have not been
assigned. At December 31, 1997 and 1996, respectively, non-assigned structured
settlements guaranteed $12,299,000 and $5,926,000 of payments under annuity
contracts for which MMIC and its reinsurers paid $4,726,000

and $3,208,000. In the event that the insurance company issuing the annuity was
unable to meet its obligation under the terms provided, MMIC would be liable for
the ultimate settlement.
    

   
9. BENEFIT PLANS
    

   
The Company has a non-contributory defined contribution pension plan covering
substantially all employees. Contributions to the plan are based upon each
covered employee's salary. The Company also sponsors a 401(k) plan covering
substantially all employees and provides a fifty percent match on employee
contributions subject to certain limitations. Total contributions charged to
expense for the years ended December 31, 1997, 1996 and 1995 were $393,000,
$371,000 and $294,000, respectively.
    

   
The Company provides an unfunded Supplemental Executive Retirement Plan (SERP)
which is a non-qualified, defined benefit retirement plan covering certain
Company officers. Benefits are based upon years of service and compensation.
Although the plan is technically unfunded, the Company has purchased life
insurance contracts for each officer, the cash value of which is designed to
coordinate with the projected benefit payments under the SERP. The cash value of
these contracts is included in other assets. The net periodic pension cost for
this plan was $363,000, $323,000 and $292,000 for the years ended December 31,
1997, 1996 and 1995, respectively. The liability recognized in the consolidated
balance sheets at December 31, 1997 and 1996 related to this plan was $2,192,000
and $1,909,000, respectively.
    

   
The Company also provides medical benefits to retirees through a defined benefit
post-retirement plan which covers substantially all employees. The net periodic
post-retirement benefit cost for the years ended December 31, 1997, 1996 and
1995 was $27,000, $30,000 and $25,000, respectively. As of December 31, 1997 and
1996, the net post-retirement benefit plan asset (liability) recognized in the
consolidated balance sheets was $4,000 and $12,000, respectively. The plan is
funded through contributions to mutual funds.

10. RECONCILIATION WITH STATUTORY ACCOUNTING PRINCIPLES (CONTINUED)
    

   
The equity of MMIHC, exclusive of the carrying value of its investment in MMIC,
is subject to redemption and therefore reported outside of shareholders' equity
under the caption redeemable stock. As a result, consolidated other
shareholders' equity as reported on the balance sheets represents equity of MMIC
only under generally accepted accounting principles.
    

   
Under Minnesota insurance statutes, MMIC is required to maintain statutory
surplus in excess of ten times its per occurrence reinsurance retention limit.
The minimum level is $7,500,000 for 1997 and 1996.
    

   
11. EARNINGS PER SHARE
    

   
The following table sets forth the computation of basic and diluted earnings per

their official capacities, provided that such person (i) has not been
indemnified by another with respect to the same matter, (ii) acted in good
faith, (iii) received no improper personal benefit, (iv) had no reasonable cause
to believe that his conduct was unlawful, and (v) reasonably believed that his
conduct was in the best interests of the corporation.

ITEM 17.  UNDERTAKINGS.

     (a)  The undersigned registrant hereby undertakes:

          (1)  To file, during any period in which offers or sales are being
          made, a post-effective amendment to this registration statement:

               (i)       To include any prospectus required by section 10(a)(3)
                         of the Securities Act of 1933;

               (ii)      To reflect in the prospectus any facts or events
                         arising after the effective date of the registration
                         statement (or the most recent post-effective amendment
                         thereof) which, individually or in the aggregate,
                         represent a fundamental change in the information set
                         forth in the registration statement;

               (iii)     To include any material information with respect to the
                         plan of distribution not previously disclosed in the
                         registration statement or any material change to such
                         information in the registration statement.


                                         II-3
<PAGE>

          (2)  That, for the purpose of determining any liability under the
          Securities Act of 1933, each such post-effective amendment shall be
          deemed to be a new registration statement relating to the securities
          offered therein, and the offering of such securities at that time
          shall be deemed to be the initial bona fide offering thereof.

          (3)  To remove from registration by means of a post-effective
          amendment any of the securities being registered which remain unsold
          at the termination of the offering.

          (4)  If the registrant is a foreign private issuer, to file a
          post-effective amendment to the registrant statement to include any
          financial statements required by 3-19 of Regulation S-X at the start
          of any delayed offering or throughout a continuous offering.

     (b)  Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers, and controlling
persons of the registrant pursuant to the foregoing provisions, or otherwise,
the registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Act and is, therefore, unenforceable.  In the event that a claim for
indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer or controlling
person of the registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Act and will
be governed by the final adjudication of such issue.

4.   DELIVERY OF POSSESSION.

If for any reason Landlord does not deliver possession of the Premises to Tenant
on the Commencement Date, and such failure is not caused by an act or omission
of Tenant, the Expiration Date shall be extended by the number of days the

Rent shall be abated until delivery of possession. Provided, however, if the
Commencement Date has been delayed by an act or omission of Tenant then Rent
shall not be abated until delivery of possession and the Expiration Date shall
not be extended. Delivery of possession shall be deemed to occur on the date
Landlord receives a Certificate of Occupancy or upon substantial completion of
the Premises, as certified by Landlord's architect. If Landlord permits Tenant
to enter into possession of the Premises before the Commencement Date, such
possession shall be subject to the provisions of this Lease, including, without
limitation, the payment of Rent.

Within ten (10) days of delivery of possession Landlord shall deliver to Tenant
and Tenant shall execute an Acceptance of Premises in which Tenant shall
certify, among other things, that (a) Landlord has satisfactorily completed
Landlord's Work to the Premises pursuant to Exhibit "D", unless written
exception is set forth thereon, and (b) that Tenant accepts the Premises.
Tenant's failure to execute and deliver the Acceptance of Premises shall be
conclusive evidence, as against Tenant, that Landlord has satisfactorily
completed Landlord's Work to the Premises pursuant to Exhibit "D".

In the event Tenant fails to take possession of the Premises following execution
of this Lease, Tenant shall reimburse Landlord promptly upon demand for all
costs incurred by Landlord in connection with entering into this Lease
including, but not limited to, broker fees and commissions, sums paid for the
preparation of a floor and/or space plan for the Premises, costs incurred in
performing Landlord's Work pursuant to Exhibit "D", loss of rental income,
attorneys' fees and costs, and any other damages for breach of this Lease
established by Landlord.

5.   INTENDED USE OF THE PREMISES.

The statement in this Lease of the nature of the business to be conducted by
Tenant in the Premises does not constitute a representation or guaranty by the
Landlord as to the present or future suitability of the Premises for the conduct
of such business in the Premises, or that it is lawful or permissible under the
certificate of occupancy issued for the Building, or is otherwise permitted by
law. Tenant's taking possession of the Premises shall be conclusive evidence, as
against Tenant, that, at the time such possession was taken, the Premises were
satisfactory for Tenant's intended use.

          statement showing in reasonable detail Landlord's projected Tax Costs
          and Operating Expenses for the succeeding calendar year. If such
          statement of projected Direct Costs indicates the Direct Costs will be
          higher than the Base Year, then the Rent due from Tenant hereunder for
          the next succeeding year shall be increased by an amount equal to
          Tenant's proportionate share of the difference between the projected
          Direct Costs for the calendar year and the Base Year. On the next
          payment date of Monthly Installments of Rent following Tenant's
          receipt of such statement, if such statement indicates that an
          estimated rent increase is due, Tenant shall pay to Landlord an amount
          equal to such monthly rent increase adjustment (as set forth on
          Landlord's statement). Thereafter, the monthly rent adjustment
          payments becoming due shall be in the amount set forth in such
          projected rent adjustment statement from Landlord. Neither Landlord's
          failure to deliver nor late delivery of such statement shall
          constitute a default by Landlord or a waiver of Landlord's right to
          any rent adjustment provided for herein.

                 6.3.2.2. On or before the first day of each April during the
          Term of this Lease, Landlord shall furnish to Tenant a written
          statement of reconciliation (the Reconciliation) showing in reasonable
          detail Landlord's actual Direct Costs for the prior year, together
          with a full statement of any adjustments necessary to reconcile any
          sums paid as estimated rent adjustments during the prior year with
          those sums actually payable for such prior year. In the event such 
          Reconciliation shows that additional sums are due from Tenant, Tenant
          shall


                                          4
<PAGE>

           pay such sums to Landlord within ten (10) days of receipt of such
           Reconciliation. In the event such Reconciliation shows that a credit
           is due Tenant, such credit shall be credited against the next sums
           becoming due from Tenant, unless this Lease has expired or been
           terminated pursuant to the terms hereof (and all sums due Landlord
           have been paid), in which event such sums shall be refunded to
           Tenant. Neither Landlord's failure to deliver nor late delivery of
           such Reconciliation to Tenant by April first shall constitute a
           default by Landlord or operate as a waiver of Landlord's right to
           collect all Additional Rent or sums due hereunder. Tenant agrees
           that no written request of such Reconciliation shall be made until
           the Reconciliation for such period shall be due. Within thirty (30)
           days after receipt of Tenant's written request therefor, Landlord
           shall deliver such Reconciliation to Tenant.

                 6.3.2.3. TENANT'S INSPECTION OF RECONCILIATION ACCOUNTING 
           RECORDS. Provided Tenant is not in default under the terms of the 
           Lease and following prior written request to Landlord, Tenant 
           shall have the right to inspect Landlord's Reconciliation 
           Accounting Records relating to Direct Costs at Landlord's 
           corporate office, during normal business hours, within thirty (30) 
           days of receipt of any annual Reconciliation of Direct Costs, for 
           the purpose of verifying the charges contained in such statement. 
           Tenant may not withhold any payment due Landlord pending 
           completion of such inspection.

     6.4.  DEFINITION OF RENT.  All costs and expenses which Tenant assumes or
agrees or is obligated to pay to Landlord under this Lease shall be deemed
Additional Rent (which, together with the Base Rent is sometimes referred to as
the Rent).

     6.5.  TAXES ON TENANT'S USE AND OCCUPANCY. In addition to the Rent and any
other charges to be paid by Tenant hereunder, Tenant shall reimburse Landlord
upon demand for any and all taxes payable by Landlord (other than net income
taxes) which are not otherwise reimbursable under this Lease, whether or not now
customary or within the contemplation of the parties, where such taxes are upon,
measured by or reasonably attributable to (a) the cost or value of Tenant's
equipment, furniture, fixtures and other personal property located in the
Premises, or the cost or value of any leasehold improvements made in or to the
Premises by or for Tenant, other than Building Standard Tenant Improvements made
by Landlord, regardless of whether title to such improvements is held by Tenant
or Landlord; (b) the gross or net Rent payable under this Lease, including,
without limitation, any rental or gross receipts tax levied by any taxing
authority with respect to the receipt of the Rent hereunder; (c) the possession,
leasing, operation, management, maintenance, alteration, repair, use or
occupancy by Tenant of the Premises or any portion thereof; or (d) this
transaction or any document to which Tenant is a party creating or transferring
an interest or an estate in the Premises. If it becomes unlawful for Tenant to
reimburse Landlord for any costs as required under this Lease, the Base Rent
shall be revised to net Landlord the same net Rent after imposition of any tax
or other charge upon Landlord as would have been payable to Landlord but for the
reimbursement being unlawful.

7.   INTEREST AND LATE CHARGES.

If Tenant fails to pay when due any Rent or Additional Rent or other amounts or
charges which Tenant is obligated to pay under the terms of this Lease, then
Tenant shall pay Landlord a late charge equal to six percent (6%) of such
installment if any such installment is not received by Landlord within five (5)
days from the date it is due. Tenant acknowledges that the late payment of any
Rent or Additional Rent will cause Landlord to lose the use of that money and
incur costs and expenses not contemplated under this Lease including, without
limitation, administrative and collection costs and processing and accounting
expenses, the exact amount of which is extremely difficult to ascertain.
Landlord and Tenant agree that this late charge represents a reasonable estimate
of such costs and expenses and is fair compensation to Landlord for the loss
suffered from such nonpayment by Tenant. Acceptance of any late charge shall not
constitute a waiver of Tenant's default with respect to such nonpayment by
Tenant nor prevent Landlord from exercising any other rights or remedies
available to Landlord under this Lease. In addition, Tenant shall be obligated
to pay interest at the maximum applicable rate then allowed by law on any unpaid
monies from the date the monies became due until payment is received by
Landlord. Late charges and interest shall be deemed Additional Rent and are
included collectively in the term Rent.

In no event shall this provision for the imposition of a late charge be deemed
to grant to Tenant a grace period or an extension of time within which to pay
any Rent or Additional Rent due hereunder or prevent Landlord from exercising
any right or remedy available to Landlord upon Tenant's failure to pay such Rent
or Additional Rent when due.

8.   SECURITY DEPOSIT.

Tenant agrees to deposit with Landlord the Security Deposit set forth in Section
2.15. upon execution of this Lease as security for Tenant's faithful performance
of its obligations under this Lease. Landlord and Tenant agree that the Security
Deposit may be commingled with funds of Landlord and Landlord shall have no
obligation or liability for payment of interest


                                          5
<PAGE>

on such deposit. Tenant shall not mortgage, assign, transfer or encumber the
Security Deposit without the prior written consent of Landlord and any attempt
by Tenant to do so shall be void, without force or effect and shall not be
binding upon the Landlord.

If Tenant fails to pay any Rent or other amount when due and payable under this
Lease, or fails to perform any of the terms hereof, Landlord may, at its option
and without prejudice to any other remedy which Landlord may have on account
thereof, appropriate and apply or use all or any portion of the Security Deposit
for Rent payments or any other amount then due and unpaid, for payment of any
amount for which Landlord has become obligated as a result of Tenant's default
or breach, and for any loss or damage sustained by Landlord as a result of
Tenant's default or breach. If Landlord so uses any of the Security Deposit,
Tenant shall, within ten (10) days after written demand therefor, restore the
Security Deposit to the full amount originally deposited. Tenant's failure to do
so shall constitute an act of default hereunder and Landlord shall have the
right to exercise any remedy provided for at Section 19. hereof.

If Tenant complies with all of the terms and conditions of this Lease, and
Tenant is not in default on any of its obligations hereunder, then within the
time period statutorily prescribed after Tenant vacates the Premises, Landlord
shall return to Tenant (or, at Landlord's option, to the last subtenant or
assignee of Tenant's interest hereunder) the Security Deposit less any
expenditures made by Landlord to repair damages to the Premises caused by Tenant
and to clean the Premises upon expiration or earlier termination of this Lease.

In the event of bankruptcy or other debtor-creditor proceedings against Tenant,
such Security Deposit shall be deemed to be applied first to the payment of Rent
and other sums due Landlord for all periods prior to the filing of such
proceedings.

9.   TENANT'S USE OF THE PREMISES.

The provisions of this Section are for the benefit of the Landlord and are not
nor shall they be construed to be for the benefit of any tenant of the Building
or Project.

     9.1.  USE.  Tenant shall use the Premises solely for the purposes set
forth in Section 2.19.

     9.2. OBSERVANCE OF LAW.  Tenant shall not use or occupy the Premises or
permit anything to be done in or about the Premises in violation of any
covenant, condition or restriction, or law, statute, ordinance or governmental
rules, regulations or requirements now in force or which may hereafter be
enacted or promulgated. Tenant shall, at its sole cost and expense, upon Notice
from Landlord, immediately discontinue any use of the Premises which is declared
by any governmental authority having jurisdiction to be a violation of law or
the Certificate of Occupancy and promptly comply with all laws, statutes,
ordinances and governmental rules, regulations or requirements now in force or
which may hereafter be in force which shall by reason of the nature of Tenant's
use or occupancy of the Premises, impose any duty upon Tenant or Landlord with
respect to the nature of Tenant's use or occupation. The judgment of any court
of competent jurisdiction or the admission by Tenant in any action or proceeding
against Tenant, whether Landlord is a party thereto or not, that Tenant has
violated any such law, statute, ordinance, or governmental regulation, rule or
requirement in the use of the Premises shall be conclusive of the fact as
between Landlord and Tenant.

     9.3. INSURANCE.  Tenant shall not do or permit to be done anything which
will invalidate or increase the cost of any fire, extended coverage or other
insurance policy covering the Building or Project and/or property located
therein, and shall comply with all rules, orders, regulations, requirements and
recommendations of Landlord's insurance carrier(s) or any board of fire
insurance underwriters or other similar body now or hereafter constituted,
relating to or affecting the condition, use or occupancy of the Premises,
excluding structural changes not related to or affected by Tenant's improvements
or acts. Tenant shall promptly upon demand reimburse Landlord for any additional
premium charged for violation of this Section.

     9.4. NUISANCE AND WASTE.  Tenant shall not do or permit anything to be done
in or about the Premises which will in any way obstruct or interfere with the
rights of other tenants or occupants of the Building or Project, or injure or
annoy them, or use or allow the Premises to be used for any improper, immoral,
unlawful or objectionable purpose, nor shall Tenant cause, maintain or permit
any nuisance in, on or about the Premises. Tenant shall not commit or suffer to
be committed any waste in or upon the Premises.

     9.5. LOAD AND EQUIPMENT LIMITS.  Tenant shall not place a load upon any
floor of the Premises which exceeds the load per square foot which such floor
was designed to carry as determined by Landlord or Landlord's structural
engineer. The cost of any such determination made by Landlord's structural
engineer in connection with Tenant's occupancy shall be paid by Tenant upon
Landlord's demand. Tenant shall not install business machines or mechanical
equipment which will in any manner cause noise objectionable to other tenants or
injure, vibrate or shake the Premises or Building.


                                          6
<PAGE>

     9.6.  HAZARDOUS MATERIAL.

Unless Tenant obtains the prior written consent of Landlord, Tenant shall not
create, generate, use, bring, allow, emit, dispose, or permit on the Premises,
Building or Shopping Center any toxic or hazardous gaseous, liquid, or solid
material or waste, or any other hazardous material defined or listed on any
applicable federal, state or local law, rule, regulation or ordinance. Tenant
shall indemnify and hold Landlord harmless from any claims, liabilities, costs
or expenses incurred or suffered by Landlord arising from such bringing,
allowing, using, permitting, generating, creating, emitting, or disposing of
toxic or hazardous material whether or not consent to same has been granted by
Landlord. Tenant's hold-harmless and indemnity obligations hereunder shall
survive the expiration or termination of this Lease.

10.  SERVICES AND UTILITIES.

Landlord agrees to furnish services and utilities to the Premises during normal
business hours on generally recognized business days subject to the Rules and
Regulations of the Building or Project and provided that Tenant is not in
default hereunder. Services and utilities shall include reasonable quantities of
electricity, heating, ventilation and air conditioning (HVAC) as required in
Landlord's reasonable judgment for the comfortable use and occupancy of the
Premises; lighting replacement for building standard lights; window washing and
janitor services in a manner that such services are customarily furnished to
comparable office buildings in the area. Landlord shall supply common area water
for drinking, cleaning and restroom purposes only. Landlord shall also maintain
and keep lighted the common stairs, common entries and restrooms in the Building
and shall furnish elevator service and restroom supplies. If Tenant desires HVAC
at any other time, Landlord shall use reasonable efforts to furnish such
service upon reasonable notice from Tenant and Tenant shall pay Landlord's
charges therefor on demand.

Landlord shall not be in default hereunder or be liable for any damages directly
or indirectly resulting from, nor shall the Rent be abated by reason of (a) the
installation, use or interruption of use of any equipment in connection with the
furnishing of any of the foregoing services, (b) failure to furnish or delay in
furnishing any such services where such failure or delay is caused by accident
or any condition or event beyond the reasonable control of Landlord, or by the
making of necessary repairs or improvements to the Premises, Building or
Project, or (c) the limitation, curtailment or rationing of, or restrictions on,
use of water, electricity, gas or any other form of energy serving the Premises,
Building or Project. Landlord shall not be liable under any circumstances for a
loss of or injury to property or business, however occurring, through, in
connection with or incidental to the failure to furnish any such services.

Tenant shall not, without the prior written consent of Landlord, use any
apparatus or device in the Premises, including, without limitation, electronic
data processing machines, punch card machines, word processing equipment,
personal computers, or machines using in excess of 120 volts, which consumes
more electricity than is usually furnished or supplied for the use of desk top
office equipment and photocopy equipment ordinarily in use in premises
designated as general office space, as determined by Landlord. Tenant shall not
connect any apparatus to electric current except through existing electrical
outlets in the Premises.

Tenant shall not consume electric current in excess of that usually furnished or
supplied for the use of premises as general office space (as determined by
Landlord), without first procuring the written consent of Landlord, which
Landlord may refuse. In the event of consent, electrical current shall be
separately metered in Tenant's name and paid for by Tenant. The cost of any such
meter and its installation, maintenance and repair shall be paid by Tenant.

Nothing contained in this Section shall restrict Landlord's right to require at
any time separate metering of utilities furnished to the Premises. If the
separate metering of utilities furnished to the Premises is due to Tenant's
excessive use of electric current, then the cost of any such meter and its
installation, maintenance and repair shall be paid by Tenant. If Landlord
requires separate metering for reasons other than Tenant's excessive consumption
of electric current, then the cost of any such meter and its installation,
maintenance and repair shall be paid by Landlord. In either event, accounts for
all such separately metered utilities shall be in Tenant's name and paid for by
Tenant and Landlord shall reduce Base Rent by the amount Landlord reasonably
estimates to be attributable to the utilities so separately metered.

If Tenant uses heat generating machines or equipment in the Premises which
effect the temperature otherwise maintained by the HVAC system, Landlord
reserves the right to install supplementary air conditioning units in the
Premises and the cost thereof, including the cost of installation, operation and
maintenance thereof, shall be paid by Tenant to Landlord upon demand therefor.

      defined in Section 13.) in the Premises, (c) the moving of Tenant's

additions, alterations or improvements upon the expiration of the Term and
restoring the Premises to the same condition as on the date Tenant took

thereof against Landlord, except in connection with damage or injury resulting
solely from the gross negligence or willful misconduct of Landlord or its
authorized agents.

      14.2. LANDLORD NOT LIABLE. Landlord shall not be liable for injury or
damage which may be sustained by the person or property of Tenant, its
employees, invitees or customers, or any other person in or about the Premises,
caused by or resulting from fire, steam, electricity, gas, water or rain which
may leak or flow from or into any part of the Premises, or from the breakage,
leakage, obstruction or other defects of pipes, sprinklers, wires, appliances,
plumbing, air conditioning, lighting fixtures or mechanical or electrical
systems, whether such damage or injury results from conditions arising upon the
Premises or upon other portions of the Building or Project or from other
sources, unless the condition was the sole result of Landlord's gross negligence
or willful misconduct. Landlord shall not be liable for any


                                          9
<PAGE>


damages arising from any act or omission of any other tenant of the Building or
Project or for the acts of persons in, on or about the Premises, Building or the
Project who are not the authorized agents of Landlord.

Tenant acknowledges that Landlord's election to provide mechanical surveillance
or to post security personnel in the Building or on the Project is solely within
Landlord's discretion; Landlord shall have no liability in connection with the
decision whether or not to provide such services and Tenant hereby waives all
claims based thereon. Landlord shall not be liable for losses due to theft,
vandalism or like causes. Tenant shall defend, indemnify and hold Landlord

15.   TENANT'S INSURANCE.

      15.1. INSURANCE REQUIREMENT. All insurance required to be carried by
Tenant hereunder shall be issued by responsible insurance companies acceptable
to Landlord and Landlord's lender and qualified to do business in the State.
Each policy shall name Landlord, and any parties designated by Landlord, as
additional insureds, as their respective interests may appear. The issuing
companies shall have a rating of not less than "A" in the latest edition of
Best's Insurance Guide and shall be at least a Class XII company. Each policy
shall contain (a) a cross-liability endorsement, (b) a provision that such
policy and the coverage evidenced thereby shall be primary and noncontributing
with respect to any policies carried by Landlord and that any coverage carried
by Landlord shall be excess insurance, and (c) a waiver by the insurer of any
right of subrogation against Landlord, its agents, employees and
representatives, which arises or might arise by reason of any act or omission of
Landlord, its agents, employees or representatives. A copy of each paid up
policy (authenticated by the insurer) or the certificate of the insurer
evidencing the existence and amount of each insurance policy required hereunder
shall be delivered to Landlord before the date Tenant is first given the right
of possession of the Premises, and thereafter within thirty (30) days after any
demand by Landlord therefor. Landlord may, at any time and from time to time,
inspect and/or copy any insurance policies required to be maintained by Tenant
hereunder. No such policy shall be cancelable or subject to reduction of
coverage or other modification or cancellation except after thirty (30) days
prior written notice to Landlord and Landlord's lender by the insurer. Tenant
shall furnish Landlord with renewals or "binders" of any such policy at least
twenty (20) days prior to the expiration thereof. Tenant agrees that if Tenant
does not take out and maintain such insurance, Landlord may (but shall not be
required to) procure said insurance on Tenant's behalf and charge the Tenant the
cost thereof together with a twenty-five percent (25%) handling charge, payable
upon demand with interest from the date such sums are extended at the rate set
forth in Section 7. hereof. Tenant shall have the right to provide such
insurance coverage pursuant to blanket policies obtained by Tenant, provided
such blanket policies expressly afford coverage to the Premises, Landlord,
Landlord's mortgagee and Tenant as required by this Lease.

      15.2. FIRE AND EXTENDED COVERAGE.  Beginning on the date Tenant is given
access to the Premises for any purpose and continuing until expiration of the
Term, Tenant shall procure, pay for and maintain in effect policies of property
insurance covering (a) all Leasehold Improvements (including any alterations,
additions or improvements as may be made by Tenant pursuant to the provisions of
Section 12. hereof), and (b) trade fixtures, merchandise and other personal
property from time to time in, on or about the Premises, in an amount not less
than one hundred percent (100%) of their actual replacement cost from time to
time, providing protection against any peril included with the classification
Fire and Extended Coverage insurance with vandalism and malicious mischief and
all risk endorsements subject to the standard exclusions among which are
earthquake and flood. The proceeds of such insurance shall be used for the
repair or replacement of the property so insured. Upon termination of this Lease
following a casualty as set forth herein, the proceeds under (a) shall be paid
to Landlord, and the proceeds under (b) above shall be paid to Tenant. Landlord
shall, during the term hereof, maintain in effect similar insurance on the
Common Area, including but not limited to insurance for sprinkler damage,
vandalism and malicious mischief, as well as, all risk, fire and extended
coverage.

      15.3. GENERAL LIABILITY AND PROPERTY DAMAGE.  Beginning on the date
Tenant is given access to the Premises for any purpose and continuing until
expiration of the Term, Tenant shall procure, pay for and maintain in effect
comprehensive general liability and property damage insurance with respect to
the construction of improvements on the Premises, the use, operation or
condition of the Premises and the operations of Tenant in, on or about the
Premises, providing personal injury and broad form property damage coverage of
not less than One Million and 00/100 Dollars ($1,000,000.00) combined single
limit for bodily injury, death and property damage liability. Landlord shall,
during the term hereof, maintain in effect similar insurance coverage on the
Common Area.

      15.4. INCREASES IN INSURANCE POLICY LIMITS.  Not less than every five (5)
years, if, in the opinion of Landlord or Landlord's lender, the amount of
Tenant's insurance policy limits for all insurance to be carried by Tenant as
set forth in this Section 15. is not adequate,


                                          10
<PAGE>

Tenant shall increase the insurance coverage as recommended by either Landlord
or Landlord's lender.

      15.5. WORKER'S COMPENSATION INSURANCE.  Beginning on the date Tenant is
given access to the Premises for any purpose and continuing until expiration of
the Term, Tenant shall procure, pay for and maintain in effect worker's
compensation insurance as required by law.

      15.6. WAIVER OF SUBROGATION.  Notwithstanding any other provision in this
Lease, Landlord and Tenant each hereby waive all rights of recovery against the
other and against the officers, employees, agents and representatives,
contractors, and invitees of the other, on account of loss by or damage to the
waiving party or its property or the property of others under its control, to
the extent that such loss or damage is insured against under any insurance
policy which may have been in force at the time of such loss or damage. Tenant
shall, upon obtaining the policies of insurance required under this Lease, give
written notice to its insurance carrier or carriers that the foregoing mutual
waiver of subrogation is contained in this Lease. In the event either party is
unable to obtain a waiver of subrogation from its insurer, this Section 15.6.
shall become void and of no force or effect.

16.   DAMAGE OR DESTRUCTION.

      16.1. DAMAGE.  If, during the term of this Lease, the Premises or the
portion of the Building necessary for Tenant's occupancy is damaged by fire or
other casualty covered by fire and extended coverage insurance carried by
Landlord, Landlord shall promptly repair the damage provided (a) such repairs
can, in Landlord's opinion, be completed, under applicable laws and regulations,
within one hundred eighty (180) days of the date a permit for such construction
is issued by the governing authority, (b) insurance proceeds are available to
pay eighty percent (80%) or more of the cost of restoration, and (c) Tenant
performs its obligations pursuant to Section 16.4. hereof. In such event, this
Lease shall continue in full force and effect, except that if such damage is not
the result of the negligence or willful misconduct of Tenant or Tenant's agents,
employees, contractors, licensees or invitees, Tenant shall be entitled to a
proportionate reduction of Rent to the extent Tenant's use of the Premises is
impaired, commencing with the date of damage and continuing until completion of
the repairs required of Landlord under Section 16.4. If the damage is due to the
fault or neglect of Tenant or its employees, there shall be no abatement of
Rent.

      16.2. REPAIR OF PREMISES IN EXCESS OF ONE HUNDRED EIGHTY DAYS.  If in
Landlord's opinion, such repairs to the Premises or portion of the Building
necessary for Tenant's occupancy cannot be completed under applicable laws and
regulations within one hundred eighty (180) days of the date a permit for such
construction is issued by the governing authority, Landlord may elect, upon
Notice to Tenant given within thirty (30) days after the date of such fire or
other casualty, to repair such damage, in which event this Lease shall continue
in full force and effect, but the Base Rent shall be partially abated as
provided in Section 16.1. If Landlord does not so elect to make such repairs,
this Lease shall terminate as of the date of such fire or other casualty.

      16.3. REPAIR OUTSIDE PREMISES.  If any other portion of the Building or
Project is totally destroyed or damaged to the extent that in Landlord's opinion
repair thereof cannot be completed under applicable laws and regulations within
one hundred eighty (180) days of the date a permit for such construction is
issued by the governing authority, Landlord may elect upon Notice to Tenant
given within thirty (30) days after the date of such fire or other casualty, to
repair such damage, in which event this Lease shall continue in full force and
effect, but the Base Rent shall be partially abated as provided in Section 16.1.
If Landlord does not elect to make such repairs, this Lease shall terminate as
of the date of such fire or other casualty.

      16.4. TENANT REPAIR.  If the Premises are to be repaired under this
Section 16., Landlord shall repair at its cost any injury or damage to the
Building and Building Standard Tenant Improvements, if any. Notwithstanding
anything contained herein to the contrary, Landlord shall not be obligated to
perform work other than Landlord's Work performed previously pursuant to Section
12.1. hereof. Tenant shall be responsible at its sole cost and expense for the
repair, restoration and replacement of any other Leasehold Improvements and
Tenant's Property. Landlord shall not be liable for any loss of business,
inconvenience or annoyance arising from any repair or restoration of any portion
of the Premises, Building or Project as a result of any damage from fire or
other casualty.

      16.5. ELECTION NOT TO PERFORM LANDLORD'S WORK.  Notwithstanding anything
to the contrary contained herein, Landlord shall provide Notice to Tenant of its
intent to repair or replace the Premises, and, within five (5) days of its
receipt of such Notice, Tenant shall provide Notice to Landlord of its intent to
reoccupy the Premises. Should Tenant fail to provide such Notice to Landlord,
then such failure shall be deemed an election by Tenant not to re-occupy the
Premises and Landlord may elect not to perform the repair or replacement of the
Premises. Such election shall not result in a termination of this Lease and all
obligations of Tenant hereunder shall remain in full force and effect,
including the obligation to pay Rent.


                                          11

      16.6.  EXPRESS AGREEMENT.  This Lease shall be considered an express
agreement governing any case of damage to or destruction of the Premises,
Building or Project by fire or other casualty, and any present or future law
which purports to govern the rights of Landlord and Tenant in such circumstances
in the absence of express agreement shall have no application.

17.   EMINENT DOMAIN.

      17.1.  WHOLE TAKING.  If the whole of the Building or Premises is
lawfully taken by condemnation or in any other manner for any public or
quasi-public purpose, this Lease shall terminate as of the date of such taking,
and Rent shall be prorated to such date.

      17.2.  PARTIAL TAKING.  If less than the whole of the Building or
Premises is so taken, this Lease shall be unaffected by such taking, provided
that (a) Tenant shall have the right to terminate this Lease by Notice to
Landlord given within ninety (90) days after the date of such taking if twenty
percent (20%) or more of the Premises is taken and the remaining area of the
Premises is not reasonably sufficient for Tenant to continue operation of its
business, and (b) Landlord shall have the right to terminate this Lease by
Notice to Tenant given within ninety (90) days after the date of such taking. If
either Landlord or Tenant so elects to terminate this Lease, the Lease shall
terminate on the thirtieth (30th) calendar day after either such Notice. The
Rent shall be prorated to the date of termination. If this Lease continues in
force upon such partial taking, the Base Rent and Tenant's Proportionate Share
shall be equitably adjusted according to the remaining Usable Area of the
Premises and Project.

      17.3.  PROCEEDS.  In the event of any taking, partial or whole, all of
the proceeds of any award, judgment or settlement payable by the condemning
authority shall be the exclusive property of Landlord, and Tenant hereby assigns
to Landlord all of its right, title and interest in any award, judgment or
settlement from the condemning authority; however, Tenant shall have the right,
to the extent that Landlord's award is not reduced or prejudiced, to claim from
the condemning authority (but not from Landlord) such compensation as may be
recoverable by Tenant in its own right for relocation expenses and damage to
Tenant's Property and damage to Leasehold Improvements installed at the sole
expense of Tenant.

      17.4.  LANDLORD'S RESTORATION.  In the event of a partial taking of the
Premises which does not result in a termination of this Lease, Landlord shall
restore the remaining portion of the Premises as nearly as practicable to its
condition prior to the condemnation or taking; provided however, Landlord shall
not be obligated to perform work other than Landlord's Work performed previously
pursuant to Section 12.1. hereof. Tenant shall be responsible at its sole cost
and expense for the repair, restoration and replacement of Tenant's Property and
any other Leasehold Improvements.

18.   ASSIGNMENT AND SUBLETTING.

No assignment of this Lease or sublease of all or any part of the Premises shall
be permitted, except as provided in this Section 18.

      18.1.  NO ASSIGNMENT OR SUBLETTING.  Tenant shall not, without the prior
written consent of Landlord, assign or hypothecate this Lease or any interest
herein or sublet the Premises or any part thereof, or permit the use of the
Premises by any party other than Tenant. Any of the foregoing acts without such
consent shall be voidable and shall, at the option of Landlord, constitute a
default hereunder. This Lease shall not, nor shall any interest of Tenant
herein, be assignable by operation of law without the prior written consent of
Landlord.

            18.1.1.  For purposes of this Section 18., the following shall be
      deemed an assignment:

                 18.1.1.1.  If Tenant is a partnership, any withdrawal or
            substitution (whether voluntary, involuntary, or by operation of
            law, and whether occurring at one time or over a period of time) of
            any partner(s) owning twenty-five (25%) or more (cumulatively) of
            any interest in the capital or profits of the partnership, or the
            dissolution of the partnership;

                 18.1.1.2.  If Tenant is a corporation, any dissolution,
            merger, consolidation, or other reorganization of Tenant, any sale
            or transfer (or cumulative sales or transfers) of the capital stock
            of Tenant in excess of twenty-five percent (25%), or any sale (or
            cumulative sales) of fifty-one (51%) or more of the value of the
            assets of Tenant provided, however, the foregoing shall not apply
            to corporations the capital stock of which is publicly traded.

      18.2.  LANDLORD'S CONSENT.  If, at any time or from time to time during
the Term hereof, Tenant desires to assign this Lease or sublet all or any part
of the Premises and Tenant is not in default under the term of the Lease, Tenant
shall submit to Landlord a written request for approval setting forth the terms
and provisions of the proposed assignment or sublease and the identity of the
proposed assignee or subtenant. Tenant shall promptly supply


                                          12
<PAGE>

Landlord with such information concerning the business background and financial
condition of such proposed assignee or subtenant as Landlord may reasonably
request. Landlord shall have the right to approve such proposed assignee or
subtenant, which approval shall not be unreasonably withheld. Landlord's consent
to any assignment shall not be construed as a consent to any subsequent
assignment, subletting, transfer of partnership interest or stock, occupancy or
use.

            18.2.1.  Landlord's approval shall be conditioned, among other
      things, on Landlord's receiving adequate assurances of future
      performance under this Lease and any sublease or assignment. In
      determining the adequacy of such assurances, Landlord may base its
      decision on such factors as it deems appropriate, including but not
      limited to:

                 18.2.1.1.  that the source of rent and other consideration due
            under this Lease, and, in the case of assignment, that the
            financial condition and operating performance of the proposed
            assignee and its guarantors, if any, shall be similar to the
            financial condition and operating performance of Tenant and its
            guarantors, if any, as of the time Tenant became the lessee under
            this Lease;

                 18.2.1.2.  that any assumption or assignment of this Lease
            will not result in increased cost or expense, wear and tear,
            greater traffic or demand for services and utilities provide by
            Landlord pursuant to Section 10. hereof and will not disturb or be
            detrimental to other tenants of Landlord;

                 18.2.1.3.  whether the proposed assignee's use of the Premises
            will include the use of Hazardous Material, or will in any way
            increase any risk to Landlord relating to Hazardous Material; and

                 18.2.1.4.  that assumption or assignment of such lease will
            not disrupt any tenant mix or balance in the Project.

            18.2.2.  The assignment or sublease shall be on the same terms and
      conditions set forth in the written request for approval given to
      Landlord, or, if different, upon terms and conditions consented to by
      Landlord;

            18.2.3.  No assignment or sublease shall be valid and no assignee
      or sublessee shall take possession of the Premises or any part thereof
      until an executed counterpart of such assignment or sublease has been
      delivered to Landlord;

            18.2.4.  No assignee or sublessee shall have a further right to
      assign or sublet except on the terms herein contained;

            18.2.5.  Any sums or other economic considerations received by
      Tenant as a result of such assignment or subletting, however denominated
      under the assignment or sublease, which exceed, in the aggregate (a) the
      total sums which Tenant is obligated to pay Landlord under this Lease
      (prorated to reflect obligations allocable to any portion of the Premises
      subleased), plus (b) any real estate brokerage commissions or fees
      payable to third parties in connection with such assignment or
      subletting, shall be shared equally by Tenant and Landlord as Additional
      Rent under this Lease without effecting or reducing any other obligations
      of Tenant hereunder.

      18.3.  TENANT REMAINS RESPONSIBLE.  No subletting or assignment shall
release Tenant of Tenant's obligations under this Lease or alter the primary
liability of Tenant to pay the Rent and to perform all other obligations to be
performed by Tenant hereunder. The acceptance of Rent by Landlord from any other
person shall not be deemed to be a waiver by Landlord of any provision hereof.
Consent to one assignment or subletting shall not be deemed consent to any
subsequent assignment or subletting. In the event of default by an assignee or
subtenant of Tenant or any successor of Tenant in the performance of any of the
terms hereof, Landlord may proceed directly against Tenant without the necessity
of exhausting remedies against such assignee, subtenant or successor. Landlord
may consent to subsequent assignments of the Lease or sublettings or amendments
or modifications to the Lease with assignees of Tenant, without notifying
Tenant, or any successor of Tenant, and without obtaining its or their consent
thereto and any such actions shall not relieve Tenant of liability under this
Lease.

      18.4.  PAYMENT OF FEES.  If Tenant assigns the Lease or sublets the
Premises or requests the consent of Landlord to any assignment or subletting,
then Tenant shall, upon demand, pay Landlord, whether or not consent is
ultimately given, an administrative fee of Two Hundred Fifty and 00/100 Dollars
($250.00) plus costs and other expenses incurred by Landlord in connection with
each such act or request.


                                          13

19.   DEFAULT.

      19.1.  TENANT'S DEFAULT.  The occurrence of any one or more of the
following events shall constitute a default and breach of this Lease by Tenant:

            19.1.1.  If Tenant abandons or vacates the Premises; or

            19.1.2.  If Tenant fails to pay any Rent or Additional Rent or any
      other charges required to be paid by Tenant under this Lease and such
      failure continues for three (3) days after receipt of Notice thereof from
      Landlord to Tenant; or

            19.1.3.  If Tenant fails to promptly and fully perform any other
      covenant, condition or agreement contained in this Lease and such failure
      continues for thirty (30) days after Notice thereof from Landlord to
      Tenant; or

            19.1.4.  If a writ of attachment or execution is levied on this
      Lease or on any of Tenant's Property; or

            19.1.5.  If Tenant makes a general assignment for the benefit of
      creditors, or provides for an arrangement, composition, extension or
      adjustment with its creditors; or

            19.1.6.  If Tenant files a voluntary petition for relief or if a
      petition against Tenant in a proceeding under the federal bankruptcy laws
      or other insolvency laws is filed and not withdrawn or dismissed within
      forty-five (45) days thereafter, or if under the provisions of any law
      providing for reorganization or winding up of corporations, any court of
      competent jurisdiction assumes jurisdiction, custody or control of Tenant
      or any substantial part of its property and such jurisdiction, custody or
      control remains in force unrelinquished, unstayed or unterminated for a
      period of forty-five (45) days; or

            19.1.7.  If in any proceeding or action in which Tenant is a party,
      a trustee, receiver, agent or custodian is appointed to take charge of
      the Premises or Tenant's Property (or has the authority to do so) for the
      purpose of enforcing a lien against the Premises or Tenant's Property; or

            19.1.8.  If Tenant is a partnership or consists of more than one
      (1) person or entity, if any partner of the partnership or other person
      or entity is involved in any of the acts or events described in Sections
      19.1.4. through 19.1.7. above.

      19.2. LANDLORD REMEDIES.  In the event of Tenant's default hereunder,
then, in addition to any other rights or remedies Landlord may have under any
law or at equity, Landlord shall have the right, at Landlord's option and
without further notice or demand of any kind, to do the following:

            19.2.1.  Terminate this Lease and Tenant's right to possession of
      the Premises and reenter the Premises and take possession thereof, and
      Tenant shall have no further claim to the Premises or under this Lease;
      or

            19.2.2.  Continue this Lease in effect, reenter and occupy the
      Premises for the account of Tenant, and collect any unpaid Rent or other
      charges which have or thereafter become due and payable; or

            19.2.3.  Reenter the Premises under the provisions of Section
      19.2.2., and thereafter elect to terminate this Lease and Tenant's right
      to possession of the Premises.

If Landlord reenters the Premises under the provisions of Sections 19.2.1. or
19.2.3. above, Landlord shall not be deemed to have terminated this Lease or the
obligation of Tenant to pay any Rent or other charges thereafter accruing unless
Landlord notifies Tenant in writing of Landlord's election to terminate this
Lease. Acts of maintenance, efforts to relet the Premises or the appointment of
a receiver on Landlord's initiative to protect Landlord's interest under this
Lease shall not constitute a termination of Tenant's right to possession. In the
event of any reentry or retaking of possession by Landlord, Landlord shall have
the right, but not the obligation, to remove all or any part of Tenant's
Property in the Premises and to place such property in storage at a public
warehouse at the expense and risk of Tenant. If Landlord elects to relet the
Premises for the account of Tenant, the rent received by Landlord from such
reletting shall be applied as follows: first, to the payment of any indebtedness
other than Rent due hereunder from Tenant to Landlord; second, to the payment of
any costs of such reletting; third, to the payment of the cost of any
alterations or repairs to the Premises; fourth to the payment of Rent due and
unpaid hereunder; and the balance, if any, shall be held by Landlord and applied
in payment of future Rent as it becomes due. If that portion of rent received
from the reletting which is applied against the Rent due hereunder is less than
the amount of the Rent due, Tenant shall pay the deficiency to Landlord promptly
upon demand by Landlord. Such deficiency shall be calculated and paid monthly.
Tenant shall also pay to Landlord, as soon as determined, any costs and expenses
incurred by Landlord in connection with such reletting or in making alterations
and repairs to the Premises which are not covered by the rent received from the
reletting.


                                          14
<PAGE>

      19.3.  DAMAGES RECOVERABLE.  Should Landlord elect to terminate this
Lease under the provisions of Section 19.2.1 or 19.2.3 above, Landlord may
recover as damages from Tenant the following:

            19.3.1.  PAST RENT.  The worth at the time of the award of any
      unpaid Rent which had been earned at the time of termination including
      the value of any Rent that was abated during the Term of the Lease; plus

            19.3.2.  RENT PRIOR TO AWARD.  The worth at the time of the award
      of the amount by which the unpaid Rent which would have been earned after
      termination until the time of award exceeds the amount of such rental
      loss that Tenant proves could have been reasonably avoided; plus

            19.3.3.  RENT AFTER AWARD.  The worth at the time of the award of
      the amount by which the unpaid Rent for the balance of the Term after the
      time of award exceeds the amount of the rental loss that Tenant proves
      could be reasonably avoided; plus

            19.3.4.  PROXIMATELY CAUSED DAMAGES.  Any other amount necessary to
      compensate Landlord for all detriment proximately caused by Tenant's
      failure to perform its obligations under this Lease or which in the
      ordinary course of things would be likely to result therefrom, including,
      but not limited to, any costs or expenses (including attorneys' fees),
      incurred by Landlord in (a) retaking possession of the Premises, (b)
      maintaining the Premises after Tenant's default, (c) preparing the
      Premises for reletting to a new tenant, including any repairs or
      alterations, and (d) reletting the Premises, including brokers'
      commissions.

"The worth at the time of the award" as used in items 19.3.1. and 19.3.2. above,
is to be computed by allowing interest at the maximum rate permitted by law to
be charged by an individual. "The worth at the time of the award" as used in
item 19.3.3. above, is to be computed by discounting the amount at the discount
rate of the Federal Reserve Bank situated nearest to the Premises at the time of
the award plus one percent (1%).

      19.4.  LANDLORD'S RIGHT TO CURE TENANT'S DEFAULT.  If Tenant defaults in
the performance of any of its obligations under this Lease, Landlord may (but
shall not be obligated to), without waiving such default, perform the same for
the account and at the expense of Tenant. Tenant shall pay Landlord all costs of
such performance immediately upon written demand therefor, and if paid at a
later date these costs shall bear interest in accordance with Section 7.

      19.5.  LANDLORD'S DEFAULT.  If Landlord fails to perform any covenant,
condition or agreement contained in this Lease within thirty (30) days after
receipt of Notice from Tenant specifying such default, or, if such default
cannot reasonably be cured within thirty (30) days if Landlord fails to commence
to cure within that thirty (30) day period, then Landlord shall be liable to
Tenant for any damages sustained by Tenant as a result of Landlord's breach;
provided, however, it is expressly understood and agreed that if Tenant obtains
a money judgment against Landlord resulting from any default or other claim
arising under this Lease, that judgment shall be satisfied only out of the
rents, issues, profits, and other income actually received on account of
Landlord's right, title and interest in the Premises, Building or Project, and
no other real, personal or mixed property of Landlord (or of any of the partners
which comprise Landlord, if any), wherever situated, shall be subject to levy to
satisfy such judgment.

      19.6.  MORTGAGEE PROTECTION.  Tenant agrees to send by certified or
registered mail to any first mortgagee or first deed of trust beneficiary of
Landlord whose address has been furnished to Tenant, a copy of any notice of
default served by Tenant on Landlord. If Landlord fails to cure such default
within the time provided for in this Lease, then such mortgagee or beneficiary
shall have such additional time to cure the default as is reasonably necessary
under the circumstances.

      19.7.  TENANT'S RIGHT TO CURE LANDLORD'S DEFAULT.  If, after Notice to
Landlord of default, Landlord (or any first mortgagee or first deed of trust
beneficiary of Landlord) fails to cure the default as provided herein, then
Tenant shall have the right to cure that default at Landlord's expense. Tenant
shall not have the right to terminate this Lease or to withhold, reduce or
offset any amount against any payments of Rent or any other charges due and
payable under this Lease except as otherwise specifically provided herein.
Tenant expressly waives the benefits of any statute now or hereafter in effect
which would otherwise afford Tenant the right to make repairs at Landlord's
expense or to terminate this Lease because of Landlord's failure to keep the
Premises in good order, condition and repair.

20.   WAIVER.

No delay or omission in the exercise of any right or remedy of Landlord upon any
default by Tenant shall impair such right or remedy or be construed as a waiver
of such default. The receipt and acceptance by Landlord of delinquent Rent shall
not constitute a waiver of


                                          15
<PAGE>

any other default; it shall constitute only a waiver of timely payment for the
particular Rent payment involved.

No act or conduct of Landlord, including, without limitation, the acceptance of
keys to the Premises, shall constitute an acceptance of the surrender of the
Premises by Tenant before the expiration of the Term. Only written
acknowledgement from Landlord to Tenant shall constitute acceptance of the
surrender of the Premises and accomplish a termination of this Lease.

Landlord's consent to or approval of any act by Tenant requiring Landlord's
consent or approval shall not be deemed to waive or render unnecessary
Landlord's consent to or approval of any subsequent act by Tenant.

Any waiver by Landlord of any default must be in writing and shall not be a
waiver of any other default concerning the same or any other provision of this
Lease.

21.   SUBORDINATION AND ATTORNMENT.

This Lease is and shall be subject and subordinate to all ground or underlying
leases which now exist or may hereafter be executed affecting the Building or
the land upon which the Building is situated, or both, and to the lien of any
mortgages or deeds of trust in any amount or amounts whatsoever now or hereafter
placed on or against the Building or on or against Landlord's interest or estate
therein, or on or against any ground or underlying lease, without the necessity
of the execution and delivery of any further instruments on the part of Tenant
to effectuate such subordination.

If any mortgagee, trustee or ground lessor shall elect to have this Lease prior
to the lien of its mortgage, deed of trust or ground lease, and shall give
written notice thereof to Tenant, this Lease shall be deemed prior to such
mortgage, deed of trust or ground lease, whether this Lease is dated prior or
subsequent to the date of said mortgage, deed of trust, or ground lease, or the
date of the recording thereof. Tenant covenants and agrees to execute and
deliver upon demand, without charge therefor, such further instruments
evidencing such subordination of this Lease to such ground or underlying leases,
and to the lien of any such mortgages or deeds of trust as may be required by
Landlord.

In the event of any foreclosure sale, transfer in lieu of foreclosure or
termination of the lease in which Landlord is lessee, Tenant shall attorn to the
purchaser, transferee or lessor as the case may be, and recognize that party as
Landlord under this Lease, provided such party acquires and accepts the Premises
subject to this Lease.

22.   TENANT ESTOPPEL CERTIFICATES.

      22.1.  LANDLORD REQUEST FOR ESTOPPEL CERTIFICATE.  Within ten (10) days
after written request from Landlord, Tenant shall execute and deliver to
Landlord or Landlord's designee, in the form requested by Landlord, a written
statement certifying, among other things, (a) that this Lease is unmodified and
in full force and effect, or is in full force and effect as modified and stating
the modifications; (b) the amount of Base Rent and the date to which Base Rent
and Additional Rent have been paid in advance; (c) the amount of any security
deposited with Landlord; and (d) that Landlord is not in default hereunder or,
if Landlord is claimed to be in default, stating the nature of any claimed
default. Any such statement may be conclusively relied upon by a prospective
purchaser, assignee or encumbrancer of the Premises.

      22.2.  FAILURE TO EXECUTE.  Tenant's failure to execute and deliver such
statement within the time required shall at Landlord's election be a default
under this Lease and shall also be conclusive upon Tenant that: (a) this Lease
is in full force and effect and has not been modified except as represented
by Landlord; (b) there are no uncured defaults in Landlord's performance and
that Tenant has no right of offset, counter-claim or deduction against Rent and
(c) not more than one month's Rent has been paid in advance.

23.   NOTICE.

Notice shall be in writing and shall be deemed duly served or given if
personally delivered, sent by certified or registered U.S. Mail, postage prepaid
with a return receipt requested, or sent by overnight courier service, fee
prepaid with a return receipt requested, as follows: (a) if to Landlord, to
Landlord's Mailing Address and to the Building manager, and (b) if to Tenant, to
Tenant's Mailing Address; provided, however, Notices to Tenant shall be deemed
duly served or given if delivered or sent to Tenant at the Premises. Landlord
and Tenant may from time to time by Notice to the other designate another place
for receipt of future Notice. Notwithstanding anything contained herein to the
contrary, any notice from Landlord to Tenant arising from Section 19. of the
Lease shall be served or given in accordance with State laws and shall be the
only notice required.

24.   TRANSFER OF LANDLORD'S INTEREST.

In the event of any sale or transfer by Landlord of the Premises, Building or
Project, and assignment of this Lease by Landlord, Landlord shall be and is
hereby entirely freed and relieved of any and all liability and obligations
contained in or derived from this Lease arising out of any act, occurrence or
omission relating to the Premises, Building, Project or Lease occurring after
the consummation of such sale or transfer, provided the purchaser shall
expressly assume all of the covenants and obligations of Landlord under this
Lease. This Lease shall not be affected by any such sale and Tenant agrees to
attorn to the purchaser or assignee provided all Landlord's obligation hereunder
are assumed by such transferee. If any security deposit or prepaid Rent has been
paid by Tenant, Landlord shall transfer the security deposit or prepaid Rent to
Landlord's successor and upon such transfer, Landlord shall be relieved of any
and all further liability with respect thereto.

25.   SURRENDER OF PREMISES.

      25.1.  CLEAN AND SAME CONDITION.  Upon the Expiration Date or earlier
termination of this Lease, Tenant shall peaceably surrender the Premises to
Landlord clean and in the same condition as when received, except for (a)
reasonable wear and tear, (b) loss by fire or other casualty, and (c) loss by
condemnation. Tenant shall remove Tenant's Property no later than the Expiration
Date. If Tenant is required by Landlord to remove any additions, alterations, or
improvements under Section 12.3., Tenant shall complete such removal no later
than the Expiration Date. Any damage to the Premises, including any structural
damage, resulting from removal of any addition, alteration, or improvement made
pursuant to Section 12.3. and/or from Tenant's use or from the removal of
Tenant's Property pursuant to Section 13.2. shall be repaired no later than the
Expiration Date by Tenant at Tenant's sole cost and expense. On the Expiration
Date Tenant shall surrender all keys to the Premises.

      25.2.  FAILURE TO DELIVER POSSESSION.  If Tenant fails to vacate and
deliver possession of the Premises to Landlord on the expiration or sooner
termination of this Lease as required by Section 25.1., Tenant shall indemnify
and hold Landlord harmless from all claims, liabilities and damages resulting
from Tenant's failure to vacate and deliver possession of the Premises,
including, without limitation, claims made by a succeeding tenant resulting from
Tenant's failure to vacate and deliver possession of the Premises and rental
loss which Landlord suffers.

      25.3.  PROPERTY ABANDONED.  If Tenant abandons or surrenders the
Premises, or is dispossessed by process of law or otherwise, any of Tenant's
Property left on the Premises shall be deemed to be abandoned, and, at
Landlord's option, title shall pass to Landlord under this Lease as by a bill of
sale. If Landlord elects to remove all or any part of such Tenant's Property,
the cost of removal, including repairing any damage to the Premises or Building
caused by such removal, shall be paid by Tenant.

26.   HOLDING OVER.

If after expiration of the Term, Tenant remains in possession of the Premises 
with Landlord's permission (express or implied), Tenant shall become a tenant 
from month to month only, upon all the provisions of this Lease (except as to 
the term and Base Rent), but the Monthly Installments of Base Rent payable by 
Tenant shall be increased to one hundred fifty percent (150%) of the Monthly 
Installments of Base Rent payable by Tenant at the expiration of the Term. 
Such monthly rent shall be payable in advance on or before the first day of 
each month. If either party desires to terminate such month to month tenancy, 
it shall give the other party not less than thirty (30) days advance Notice 
of the date of termination.

27.   RULES AND REGULATIONS.

Tenant agrees to comply with (and cause its agents, contractors, employees and
invitees to comply with) the rules and regulations attached hereto as Exhibit
"E" and with such reasonable modifications thereof and additions thereto as
Landlord may from time to time make.  Landlord shall not be liable for any
violation of said rules and regulations by other tenants or occupants of the
Building or Project.

28.   CERTAIN RIGHTS RESERVED BY LANDLORD.

Landlord reserves the following rights, exercisable without (a) liability to
Tenant for damage or injury to property, person or business; (b) causing an

of the Premises or the Building or Landlord's interest therein, or as may be
necessary or desirable for the operation or improvement of the Building or in
order to comply with laws, orders or requirements of governmental or other
authority. Landlord agrees to use its best efforts (except in an emergency) to
minimize interference with Tenant's business in the Premises in the course of
any such entry.

29.   ADVERTISEMENTS AND SIGNS.

Tenant shall not affix, paint, erect or inscribe any sign, projection, awning,
signal or advertisement of any kind to any part of the Premises, Building or
Project, including without limitation the inside or outside of windows or doors,
without the prior written consent of Landlord. Landlord shall have the right to
remove any signs or other matter installed without Landlord's permission,
without being liable to Tenant by reason of such removal, and to charge the cost
of removal to Tenant as Additional Rent hereunder, payable within ten (10) days
of written demand by Landlord.

30.   RELOCATION OF PREMISES.

Landlord shall have the right to relocate the Premises to another part of the
Building in accordance with the following:

      30.1.  The new premises shall be substantially the same in size,
dimensions, configuration, decor and nature as the Premises described in this
Lease, and if the relocation occurs after the Commencement Date, shall be placed
in that condition by Landlord at its cost.

      30.2.  Landlord shall give Tenant at least thirty (30) days Notice of
Landlord's intention to relocate the Premises.

      30.3.  As nearly as practicable, the physical relocation of the Premises
shall take place on a weekend and shall be completed before the following
Monday. If the physical relocation has not been completed in that time, Base
Rent shall abate in full from the time the physical relocation commences to the
time it is completed. Upon completion of such relocation, the new Premises shall
become the Premises under this Lease.

      30.4.  All reasonable costs incurred by Tenant as a result of the
relocation shall be paid by Landlord.

      30.5.  If the new premises are smaller than the Premises as it existed
before the relocation, Base Rent shall be reduced proportionately.

      30.6.  The parties hereto shall immediately execute an amendment to this
Lease setting forth the relocation of the Premises and the reduction of Base
Rent, if any.

31.   GOVERNMENT ENERGY OR UTILITY CONTROLS.

In the event of imposition of federal, state or local government controls,
rules, regulations, or restrictions on the use or consumption of energy or other
utilities during the Term, both Landlord and Tenant shall be bound thereby. In
the event of a difference in interpretation by Landlord and Tenant of any such
controls, the interpretation of Landlord shall prevail and Landlord shall have
the right to enforce compliance therewith, including the right of entry into the
Premises to effect compliance.


                                          18
<PAGE>

32.   FORCE MAJEURE.

Any prevention, delay or stoppage of work to be performed by Landlord or Tenant
which is due to strikes, labor disputes, inability to obtain labor, materials,
equipment or reasonable substitutes therefor, acts of God, governmental
restrictions or regulations or controls, judicial orders, enemy or hostile
government actions, civil commotion, fire or other casualty, or other causes
beyond the reasonable control of the party obligated to perform hereunder, shall
excuse performance of the work by that party for a period equal to the duration
of that prevention, delay or stoppage. Nothing in this Section 32. shall excuse
or delay Tenant's obligation to pay Rent or other charges under this Lease.

33.   BROKERAGE FEES.

Tenant warrants and represents that it has not dealt with any real estate broker
or agent in connection with this Lease or its negotiation except the Listing and
Leasing Agent(s) set forth in Section 2.9. of this Lease. Tenant shall indemnify
and hold Landlord harmless from any cost, expense or liability (including costs
of suit and reasonable attorneys' fees) for any compensation, commission or fees
claimed by any other real estate broker or agent in connection with this Lease
or its negotiation by reason of any act of Tenant.

34.   QUIET ENJOYMENT.

Tenant, upon payment of Rent and performance of all of its obligations under
this Lease, shall peaceably, quietly and exclusively enjoy possession of the
Premises without unwarranted interference by Landlord or anyone acting or
claiming through Landlord, subject to the terms of this Lease and to any
mortgage, lease, or other agreement to which this Lease may be subordinate.

35.   MISCELLANEOUS.

      35.1.  ACCORD AND SATISFACTION; ALLOCATION OF PAYMENTS.  No payment by
Tenant or receipt by Landlord of a lesser amount than the Rent provided for in
this Lease shall be deemed to be other than on account of the earliest due Rent,
nor shall any endorsement or statement on any check or letter accompanying any
check or payment as Rent be deemed an accord and satisfaction, and Landlord may
accept such check or payment without prejudice to Landlord's right to recover
the balance of the Rent or pursue any other remedy provided for in this Lease.
In connection with the foregoing, Landlord shall have the absolute right in its
sole discretion to apply any payment received from Tenant to any account or
other payment of Tenant then not current and due or delinquent.

      35.2.  ADDENDA.  If any provision contained in an addendum to this Lease
is inconsistent with any other provision herein, the provision contained in the
addendum shall control, unless otherwise provided in the addendum.

      35.3.  ATTORNEYS' FEES.  If any action or proceeding is brought by either
party against the other pertaining to or arising out of this Lease, the finally
prevailing party shall be entitled to recover all costs and expenses, including
reasonable attorneys' fees, incurred on account of such action or proceeding.

      35.4.  CAPTIONS AND SECTION NUMBERS.  The captions appearing in the body
of this Lease have been inserted as a matter of convenience and for reference
only and in no way define, limit or enlarge the scope or meaning of this Lease.
All references to Section numbers refer to Sections in this Lease.

      35.5.  CHANGES REQUESTED BY LENDER.  Neither Landlord or Tenant shall
unreasonably withhold its consent to changes or amendments to this Lease
requested by the lender on Landlord's interest, so long as such changes do not
alter the basic business terms of this Lease or otherwise materially diminish
any rights or materially increase any obligations of the party from whom consent
to such change or amendment is requested.

      35.6.  CHOICE OF LAW.  This Lease shall be construed and enforced in
accordance with the Laws of the State.

      35.7.  CONSENT.  Notwithstanding anything contained in this Lease to the
contrary, Tenant shall have no claim, and hereby waives the right to any claim
against Landlord for money damages, by reason of any refusal, withholding or
delaying by Landlord of any consent, approval or statement of satisfaction, and,
in such event, Tenant's only remedies therefor shall be an action for specific
performance, injunction or declaratory judgment to enforce any right to such
consent, approval or statement of satisfaction.


                                          19
<PAGE>

      35.8.  CORPORATE AUTHORITY.  If Tenant is a corporation, each individual
signing this Lease on behalf of Tenant represents and warrants that he is duly
authorized to execute and deliver this Lease on behalf of the corporation, and
that this Lease is binding on Tenant in accordance with its terms. Tenant shall,
at Landlord's request, deliver a certified copy of a resolution of its board of
directors authorizing such execution.

      35.9.  COUNTERPARTS.  This Lease may be executed in multiple
counterparts, all of which shall constitute one and the same Lease.

      35.10.  EXECUTION OF LEASE; NO OPTION.  The submission of this Lease to
Tenant shall be for examination purposes only and does not and shall not
constitute a reservation of or option for Tenant to Lease, or otherwise create
any interest of Tenant in the Premises or any other premises within the Building
or Project. Execution of this Lease by Tenant and its return to Landlord shall
not be binding on Landlord, notwithstanding any time interval, until Landlord
has in fact signed and delivered this Lease to Tenant.

      35.11.  FURNISHING OF FINANCIAL STATEMENTS; TENANT'S REPRESENTATIONS.  In
order to induce Landlord to enter into this Lease, Tenant agrees that it shall
promptly furnish Landlord, from time to time, upon Landlord's written request,
with financial statements reflecting Tenant's current financial condition.
Tenant represents and warrants that all financial statements, records and
information furnished by Tenant to Landlord in connection with this Lease are
true, correct and complete in all respects.

      35.12.  FURTHER ASSURANCES.  The parties agree to promptly sign all
documents reasonably requested to give effect to the provisions of this Lease.

      35.13.  PRIOR AGREEMENTS; AMENDMENTS.  This Lease and the schedules and
riders attached, if any, form a part of this Lease together with the rules and
regulations set forth on Exhibit "E" attached hereto, and set forth all the
covenants, promises, assurances, agreements, representations, conditions,
warranties, statements, and understandings (Representations) between the
Landlord and Tenant concerning the Premises and the Building and Project, and
there are no Representations, either oral or written, between them other than
those in this Lease.

This Lease supersedes and revokes all previous negotiations, arrangements,
letters of intent, offers to lease, lease proposals, brochures,
representations, and information conveyed, whether oral or in writing, between
the parties hereto or their respective representatives or any other person
purporting to represent the Landlord or Tenant. Tenant acknowledges that it has
not been induced to enter into this Lease by any Representations not set forth
in this Lease, and that it has not relied on any such Representations. Tenant
further acknowledges that no such Representations shall be used in the
interpretation or construction of this Lease, and that Landlord shall have no
liability for any consequences arising as a result of any such Representations.

Except as herein otherwise provided, no subsequent alteration, amendment,
change, or addition to this Lease shall be binding upon Landlord or Tenant
unless in writing and signed by each of the parties.

      35.14.  RECORDING.  Tenant shall not record this Lease without the prior
written consent of Landlord. Tenant, upon the request of Landlord, shall execute
and acknowledge a short form memorandum of this Lease for recording purposes.

      35.15.  SEVERABILITY.  A final determination by a court of competent
jurisdiction that any provision of this Lease is invalid shall not affect the
validity of any other provision, and any provision so determined to be invalid
shall, to the extent possible, be construed to accomplish its intended effect.

      35.16.  SUCCESSORS AND ASSIGNS.  This Lease shall apply to and bind the
heirs, personal representatives, and successors and assigns of the parties.

      35.17.  TIME OF THE ESSENCE.  Time is of the essence of this Lease.

TELECOMMUNICATIONS

Section 36.1. adds to and amends the Lease as follows:

     (a) Telecommunications Companies. Tenant and Tenant's telecommunications 
companies, including but not limited to local exchange telecommunications 
companies and alternative access vendor services companies 
("Telecommunications Companies"), shall have no right of access to and within 
the lands or Buildings comprising Landlord's real property for the 
installation and operation of telecommunications systems including but not 
limited to voice, video, data, and any other telecommunications services 
provided over wire, fiber optic, microwave, wireless and any other 
transmission systems, for part or all of Tenant's telecommunications within 
the Building and from the Building to any other location (hereinafter 
collectively referred to as "Telecommunications Systems"), without Landlord's 
prior written consent, which such consent shall not be unreasonably withheld. 
Notwithstanding the foregoing, Tenant may perform any installation, repair 
and maintenance to its Telecommunications Systems without Landlord's consent 
where the equipment being installed, repaired or maintained is not located in 
an area in which the Telecommunications Systems or any part thereof of any 
other tenant, or of Landlord, are located.

     (b)  Tenant's Obligations. If at any time, Tenant's Telecommunications
Companies or appropriate governmental authorities relocate the point of
demarcation from the location of Tenant's telecommunications equipment in
Tenant's telephone equipment room or other location, to some other point, or in
any other manner transfer any obligations or liabilities for telecommunications
to Landlord or Tenant, whether by operation of law or otherwise, upon Landlord's
election, Tenant shall, at Tenant's sole expense and cost: (1) within thirty
(30) days after notice is first given to Tenant of Landlord's election, cause to
be completed by an appropriate telecommunications engineering entity approved in
advance in writing by Landlord, all details of the Telecommunications Systems
serving Tenant in the Building which details shall include all appropriate
plans, schematics, and specifications; and (2) immediately undertake the
operation, repair and maintenance of the Telecommunications Systems serving
Tenant in the Building; and (3) upon the termination of the Lease for any
reason, or upon expiration of the Lease, immediately effect the complete removal
of all or any portion or portions of the Telecommunications Systems serving
Tenant in the Building and repair any damage caused thereby (to Landlord's
reasonable satisfaction).

     Prior to the commencement of any alterations, additions, or modifications
to the Telecommunications Systems serving Tenant in the Building, except for
minor changes, Tenant shall first obtain Landlord's prior written consent by
written request accompanied by detailed plans, schematics, and specifications
showing all alterations,


                                          1
<PAGE>

additions and modifications to be performed, with the time schedule for
completion of the work, and the identity of the entity which will perform the
work, for which, except as otherwise provided in Paragraph (c) below, Landlord
may withhold consent in its sole and absolute discretion.

     (c)  Landlord's Consent. Without in any way limiting Landlord's right to
withhold its consent to a proposed request for access, or for alterations,
additions or modifications of the Telecommunications Systems serving Tenant in
the Building, Landlord shall consider the following factors in making its
determination:

          (i) If the proposed actions of Tenant and its Telecommunications
     Companies will impose new obligations on Landlord, or expose Landlord to
     liability of any nature or description, or increase Landlord's insurance
     premiums for the Building, or create liabilities for which Landlord is
     unable to obtain insurance protection, or imperil Landlord's insurance
     coverage;

          (ii) If Tenant's Telecommunications Companies are unwilling to pay
     reasonable monetary compensation for the use and occupation of the Building
     for the Telecommunications Systems;

          (iii) If Tenant and its Telecommunications Companies would cause any
     work to be performed that would adversely affect the land and Building or
     any space in the Building in any manner;

          (iv) If Tenant encumbers or mortgages its interest in any
     telecommunications wiring or cabling; or

          (v)  If Tenant is in default under this Lease.

     (d)  Indemnification. Tenant shall indemnify and hold harmless Landlord and
its employees, agents, officers, and directors from and against any claims,
demands, penalties, fines, liabilities, settlements, damages, costs, or expenses
of any kind or nature, known or unknown, contingent or otherwise, arising out of
or in any way related to the acts and omissions of Tenant, Tenant's officers,
directors, employees, agents, contractors, subcontractors, subtenants, and
invitees with respect to (1) any Telecommunications Systems serving Tenant in
the Building which are on, from, or affecting the land and Building; (2) any
personal injury (including wrongful death) or property damage (real or personal)
arising out of or related to any Telecommunications Systems serving Tenant in
the Building which are on, from, or affecting the Building; (3) any lawsuit
brought or threatened, settlement reached, or governmental order relating to
such Telecommunications Systems; (4) any violations of laws, orders,
regulations, requirements, or demands of governmental authorities, or any
reasonable policies or requirements of Landlord, which are based upon or in any
way related to such Telecommunications Systems, including, without limitation,
attorney and consultant fees, court costs, and litigation expenses. This
indemnification and hold harmless agreement will survive this Lease. Under no
circumstances shall Landlord be required to maintain, repair or replace any
Building systems or any portions thereof, when such maintenance, repair or
replacement is caused in whole or in part by the failure of any such system or
any portions thereof, and/or the requirements of any governmental authorities.
Under no circumstances shall Landlord be liable for interruption in
telecommunications services to Tenant or any other entity affected, for
electrical spikes


                                          2

or surges, or for any other cause whatsoever, whether by Act of God or
otherwise, even if the same is caused by the ordinary negligence of Landlord,
Landlord's contractors, subcontractors, or agents or other tenants, subtenants,
or their contractors, subcontractors, or agents.

IN WITNESS WHEREOF, Landlord and Tenant have executed this Addendum to Lease as
of the date first above written.

     For purposes of this Article, the term "extra contractual obligation" shall
mean an obligation imposed upon the Company by judgment or decree which is not
covered under any other provision of this Agreement and which arises from the

Company, acting individually or collectively or in collusion with any individual
or corporation or any other organization or party involved in the investigation,
defense or settlement of any claim covered hereunder.

or protects the Company against claims which are the subject matter of this
Article and any contribution, subrogation, or recovery shall inure to the
benefit of the Reinsurers and shall be deducted to arrive at the amount of the
Company's net loss.

                     or termination of the reinsurance, if any, then in effect.

     (b)  NET PROVISIONAL REINSURANCE PREMIUM EARNED

          This term shall mean the First Excess Cover reinsurance premium

<PAGE>

time and date, provided that the injury which results in each such claim occurs
on or after the retroactive date indicated in each such policy. However, this
Agreement shall not apply to professional liability claims made to the Company

the return of the premium paid for business reported but not reinsured under
this Agreement.

     The Company shall allow the Reinsurers to inspect, at reasonable times, the
records of the Company relevant to the business reinsured under this Agreement,

<PAGE>

files concerning claims, losses, or legal proceedings which involve or are
likely to involve the Reinsurers.


ARTICLE XXIII - ARBITRATION

     Any unresolved difference of opinion between the Reinsurers and the Company
shall be submitted to arbitration by three arbitrators. One arbitrator shall be
chosen by the Reinsurers, and one shall be chosen by the Company. The third
arbitrator shall be chosen by the other two arbitrators within ten (10) days
after they have been appointed. If the two arbitrators cannot agree upon a third
arbitrator, each arbitrator shall nominate three persons of whom the other shall
reject two. The third arbitrator shall then be chosen by drawing lots. If either
party fails to choose an arbitrator within thirty (30) days after receiving the
written request of the other party to do so, the latter shall choose both
arbitrators, who shall choose the third arbitrator. The arbitrators shall be
impartial and shall be present or former officials of property or casualty
insurance or reinsurance companies.

     The party requesting arbitration (the "Petitioner") shall submit its 
brief to the arbitrators within thirty (30) days after notice of the 
selection of the third arbitrator. Upon receipt of the Petitioner's brief, 
the other party (the "Respondent") shall have thirty (30) days to file a 
reply brief.  On receipt of the Respondent's brief, the Petitioner shall have 
twenty (20) days to file a rebuttal brief.  Respondent shall have twenty (20) 
days from the receipt of Petitioner's rebuttal brief to file its rebuttal 
brief.  The arbitrators may extend the time for filing of briefs at the 
request of either party.

     The arbitrators are relieved from judicial formalities and, in addition to
considering the rules of law and the customs and practices of the insurance and
reinsurance business, shall make their award with a view to effecting the intent
of this Agreement. The decision of the majority shall be final and binding upon
the parties. The costs of arbitration, including the fees of the arbitrators,
shall be shared equally unless the arbitrators decide otherwise. The arbitration
shall be held at the times and places agreed upon by the arbitrators.

ARTICLE XXIV - INSOLVENCY OF THE COMPANY

     In the event of the insolvency of the Company, the reinsurance proceeds
will be paid to the Company or the liquidator on the basis of the amount of the
claim allowed in the insolvency proceeding without diminution by reason of the
inability of the Company to pay all or part of the claim.

     The Reinsurers shall be given written notice of the pendency of each claim
against the Company on the policy(ies) reinsured hereunder within a reasonable
time after such claim is filed in the insolvency proceedings. The Reinsurers
shall have the right to investigate each such claim and to interpose, at their
own expense, in the proceeding where such claim is to be adjudicated, any
defenses which it may deem available to the Company or its liquidator. The
expense thus incurred by the Reinsurers shall be chargeable, subject to court
approval, against the insolvent Company as part of the expense of liquidation to
the extent of a proportionate share of the benefit which may accrue to the
Company solely as a result of the defense undertaken by the Reinsurers.

IT IS ALSO AGREED that the following Articles shall apply to the SUBSCRIBING

     "ARTICLE XXVI - UNAUTHORIZED REINSURERS

     A.    If the Reinsurers are unauthorized in any state of the United States
           of America or the District of Columbia, the Reinsurers agree to fund
           their share of the Company's ceded outstanding loss and loss
           adjustment expense reserves including incurred but not reported loss
           reserves (to be mutually agreed at each December 31) by:

           1.   Clean, irrevocable and unconditional letters of credit issued
                and confirmed, if confirmation is required by the insurance
                regulatory authorities involved, by a bank or banks meeting the
                NAIC Securities Valuation Office credit standards for issuers
                of letters of credit and acceptable to said insurance
                regulatory authorities; and/or


                                                                     Page 1 of 4
<PAGE>

           2.   Escrow accounts for the benefit of the Company; and/or

           3.   Cash advances;

           if, without such funding, a penalty would accrue to the Company on
           any financial statement it is required to file with the insurance
           regulatory authorities involved. The Reinsurers, at their sole
           option, may fund in other than cash if its method and form of
           funding are acceptable to the insurance regulatory authorities
           involved.

     B.    With regard to funding in whole or in part by letters of credit, it
           is agreed that each letter of credit will be in a form acceptable to
           insurance regulatory authorities involved, will be issued for a term
           of at least one year and will include an "evergreen clause," which
           automatically extends the term for at least one additional year at
           each expiration date unless written notice of non-renewal is given
           to the Company not less than 30 days prior to said expiration date.
           The Company and the Reinsurers further agree, notwithstanding
           anything to the contrary in this Contract, that said letters of
           credit may be drawn upon by the Company or its successors in
           interest at any time, without diminution because of the insolvency
           of the Company or the Reinsurers, but only for one or more of the
           following purposes:

           1.   To reimburse itself for the Reinsurers' share of losses and/or
                loss adjustment expense paid under the terms of policies
                reinsured hereunder, unless paid in cash by the Reinsurers;

           2.   To reimburse itself for the Reinsurers' share of any other
                amounts claimed to be due hereunder, unless paid in cash by the
                Reinsurers;

           3.   To fund a cash account in an amount equal to the Reinsurers'
                share of any ceded outstanding loss and loss adjustment expense
                reserves including incurred but not reported loss reserves (to
                be mutually agreed at each December 31) funded by means of a
                letter of credit which is under non-renewal notice, if said
                letter of credit has not been renewed or replaced by the
                Reinsurers 10 days prior to its expiration date;

           4.   To refund to the Reinsurers any sum in excess of the actual
                amount required to fund the Reinsurers' share of the Company's
                ceded outstanding loss and loss adjustment expense reserves
                including incurred but not reported loss reserves (to be
                mutually agreed at each December 31), if so requested by the
                Reinsurers.

           In the event the amount drawn by the Company on any letter of credit
           is in excess of the actual amount required for B(1) or B(3), or in
           the case of B(2), the actual amount determined to be due, the
           Company shall promptly return to the Reinsurers the excess amount so
           drawn.


                                                                 Page 2 of 4
<PAGE>

     ARTICLE XXVII - NET RETAINED LINES (BRMA 32B)

     A.    This Contract applies only to that portion of any policy which the
           Company retains net for its own account, and in calculating the
           amount of any loss hereunder and also in computing the amount or
           amounts in excess of which this Contract attaches, only loss or
           losses in respect of that portion of any policy which the Company
           retains net for its own account shall be included.

     B.    The amount of the Reinsurers' liability hereunder in respect of any
           loss or losses shall not be increased by reason of the inability of
           the Company to collect from any other reinsurers, whether specific
           or general, any amounts which may have become due from such
           reinsurers, whether such inability arises from the insolvency of
           such other reinsurers or otherwise.

     ARTICLE XXVIII - CURRENCY (BRMA 12A)

     A.    Whenever the word 'Dollars' or the '$' sign appears in this
           Agreement, they shall be construed to mean United States Dollars and
           all transactions under this Agreement shall be in United States
           Dollars.

     B.    Amounts paid or received by the Company in any other currency shall
           be converted to United States Dollars at the rate of exchange at the

     A.    The Reinsurers have agreed to allow for the purpose of paying the
           Federal Excise Tax the applicable percentage of the premium payable
           hereon as imposed under Section 4371 of the Internal Revenue Code to
           the extent such premium is subject to the Federal Excise Tax.

     B.    In the event of any return premium becoming due hereunder the
           Reinsurers will deduct the applicable percentage from the return
           premium payable hereon and the Company or its agent should take
           steps to recover the tax from the United States Government.

     A.    It is agreed that in the event the Reinsurers fail to pay any amount
           claimed to be due hereunder, the Reinsurers, at the request of the
           Company, will submit to the jurisdiction of a court of competent
           jurisdiction within the United States. Nothing in this Article
           constitutes or should be understood to constitute a waiver of the

           jurisdiction in the United States, to remove an action to a United
           States District Court, or to seek a transfer of a case to another
           court as permitted by the laws of the United States or of any state
           in the United States.

     B.    Further, pursuant to any statute of any state, territory or district
           of the United States which makes provision therefor, the Reinsurers
           hereby designate the party named in its Interests and Liabilities

           this Agreement.

                         ARTICLE 1. ESTABLISHMENT AND PURPOSE

     SECTION 1.1  ESTABLISHMENT.  Midwest Medical Insurance Holding Company
("Company"), through its predecessor, Minnesota Medical Management, Inc.,
established a nonqualified supplemental retirement income plan for the benefit
of specified Executive Employees of the Company effective as of March 1, 1986.
This plan was originally known as the MINNESOTA MEDICAL MANAGEMENT, INC.

hereby amends and restates the Plan, which is now known as the MIDWEST MEDICAL

are in the employ of the Company on May 14, 1997, or are hired after May 14,
1997.

     SECTION 1.2  PURPOSE.  The purpose of the Plan is to supplement the
benefits payable to Participants and their Beneficiaries under the federal
Social Security Act, the Midwest Medical Insurance Holding Company 1986 Pension
Plan, and the Polaris Qualified Pension Plan.

          (b)  "AVERAGE MONTHLY COMPENSATION"  for a Participant means the

          (c)  "BENEFICIARY"  means the persons or trusts designated by a
     Participant in writing pursuant to Section 5.1 of the Plan as being
     entitled to receive any benefit payable under the Plan by reason of the

     Plan.

          (r)  "PLAN" means the "Midwest Medical Insurance Holding Company
     Supplemental Executive Retirement Plan" as set forth herein and as amended

          (s)  "PRIMARY SOCIAL SECURITY BENEFIT" means the monthly primary
     old-age insurance benefit which a Participant is or would be entitled to
     receive under the federal Social Security Act. For this purpose, it shall
     be assumed that the Participant applies for such benefit and does not
     disqualify himself from receiving it by reason of earnings he may receive
     in excess of any earnings limit


                                         -5-
<PAGE>

     on full entitlement to benefits or any other reason within the control of
     the Participant.

          For purposes of determining the Primary Social Security Benefit amount
     in any case in which the Employee's termination of employment occurs prior
     to his sixty-second birthday, the Primary Social Security Benefit shall be
     determined in the same manner as in the case of termination of employment
     at his sixty-second birthday, except that the computation shall be made on
     the assumption that he will continue to receive, until his sixty-second
     birthday, annual compensation that would be treated as wages for purposes
     of the federal Social Security Act at the same rate as his compensation for
     the Plan Year ending with or next preceding the date of his termination of
     employment, that the federal Social Security Act as in effect on the last
     day of the month coincident with or immediately preceding his termination
     of employment will remain unchanged until his sixty-second birthday, and

     Date is later than May 14, 1997, the Participant's Target Percentage shall
     be seventy


                                         -6-
<PAGE>

     percent (70%) unless a different Target Percentage has been designated by
     the Committee.

          (v)  "YEARS OF SERVICE" of a Participant means the number of
     consecutive twelve-month periods (including periods prior to the Effective
     Date of this Plan) commencing on the date of the Participant's first Hour
     of Service (and anniversaries thereof) and ending on the date of his
     termination of employment, plus any additional Years of Service granted
     pursuant to Article 9. Fractional Years of Service shall be counted by
     crediting the Participant with one-twelfth of a Year of Service for each
     calendar month during which the Participant is employed by the Company for
     at least 16 days, including weekends and holidays.

     SECTION 2.2    GENDER AND NUMBER.  Except as otherwise indicated by

     SECTION 3.1    WHO MAY PARTICIPATE.  Participation in the Plan (as restated
herein) shall be limited to those Executive Employees who are listed on Schedule
A, attached hereto and made a part hereof, or who are otherwise selected to be
Participants by the Committee from time to time in its sole discretion. No
person employed by the Company in any capacity shall have a right, solely by
reason of such employment, to be a Participant in the Plan.

     SECTION 3.2    TIME AND CONDITIONS OF PARTICIPATION.  An eligible Executive
Employee shall become a Participant only upon (a) designation as a Participant
by action of the Committee


                                         -7-
<PAGE>

and (b) compliance with such terms and conditions as the Committee may from time
to time establish for the implementation of the Plan, including, but not limited
to, any conditions that the Committee may deem necessary or appropriate for the
Company to meet its obligations under the Plan.

     SECTION 3.3    TERMINATION OF PARTICIPATION.  Once an Executive Employee
has become a Participant in the Plan, participation shall continue until the
first to occur of (a) payment in full of all benefits to which the Participant
or designated Beneficiary is entitled under the Plan or (b) the occurrence of an
event specified in this Article which results in loss of benefits.

     SECTION 3.4    EFFECT OF TERMINATION OF EMPLOYMENT PRIOR TO EARLY
RETIREMENT DATE.  A Participant shall cease to be a Participant and shall
forfeit all rights to benefits under this Plan if his employment with the
Company is terminated for any reason, including death or disability, prior to
his Early Retirement Date, except as provided in Article 9. A Participant's
employment shall not be deemed to be terminated by reason of an approved leave
of absence granted by the Company.

     SECTION 3.5    EFFECT OF DISABILITY.  If a Participant shall be determined
to be disabled under the provisions of any policy of disability income insurance
maintained by the Company or under any waiver of premium provision on a policy
of life insurance maintained by the Company on the life of the Participant, or,
in the absence of any such insurance, upon a determination by the Committee
based on the opinion of a physician of the Committee's choice that the
Participant is unable to perform the major duties of the Participant's
employment, then, solely for purposes of determining the Participant's right to
benefits under the Plan, such Participant shall not be deemed to have terminated
employment with the Company until the date on which the


                                         -8-
<PAGE>

Participant has been disabled for six (6) consecutive months or, if earlier, the
date of the Participant's death.

     SECTION 3.6    REEMPLOYMENT.  Except to the extent that the Company and the
Participant agree in writing to the contrary, if a person who ceased to be a
Participant by reason of a termination of employment prior to his Early
Retirement Date, is reemployed by the Company and becomes a Participant, such
Participant's rights under the Plan shall be determined as if such reemployment
constituted the Participant's initial employment. All Compensation, Hours of
Service, Years of Service, and years of plan participation for periods prior to
the date of such Participant's reemployment shall be disregarded in determining
such Participant's rights and benefits under this Plan.

     SECTION 3.7    FORFEITURE FOR MISCONDUCT.  Notwithstanding any other
provision of the Plan, no benefits shall be paid to any Participant who has been
convicted (by guilty plea or by adjudication which has become final) of, or has
entered a plea of nolo contendere to a charge of, fraud, embezzlement, or other
criminal misconduct involving the assets or business of the Company. If a
Participant is receiving benefits at the time such final adjudication or plea
shall occur, no further benefits shall be paid to the Participant or to the
Participant's Beneficiary in the event of the Participant's death. At any time
after the filing (or issuance of an indictment) for any criminal charges, which,
if sustained, would terminate a Participant's rights to benefits hereunder, the
Company may defer any benefit payments which would otherwise become due
hereunder until such criminal charges have been finally determined. Any amounts
so deferred shall be forfeited or brought current by lump sum payment (without
interest), as the case may be, once a final determination has been made.


                                         -9-

     SECTION 3.8    MISSING PERSONS.  If the Company is unable to locate the
Participant or his Beneficiary for purposes of making distribution, the amount
of a Participant's benefits under this Plan that would otherwise be considered
as nonforfeitable shall be forfeited effective four (4) years after (i) the last
date a payment of said benefit was made, if at least one such payment was made,
or (ii) the first date a payment of said benefit was directed to be made by the
Company, if no payments had been made. If such person is located after the date
of such forfeiture, the benefits for such Participant or Beneficiary shall not
be reinstated.

     SECTION 3.9    RELATIONSHIP TO OTHER PLANS.  Participation in the Plan
shall not preclude or limit the participation of the Participant in any other
fringe benefit program or plan sponsored by the Company for which such
Participant would otherwise be eligible. Unless otherwise specifically provided
for in such other program or plan, no portion of any costs incurred by the
Company in providing benefits hereunder shall be considered "compensation" of
the Participant for purposes of determining the contributions or benefits under
such program or plan.


                                 ARTICLE 4. BENEFITS

     SECTION 4.1    NORMAL BENEFIT AMOUNT.  A Participant shall be eligible to
receive a benefit under this Plan upon termination of employment on or after his
Early Retirement Date. The benefit shall be paid in the Standard Form of
Benefit, in an amount determined under Sections 4.3 and 4.4. Benefits are
calculated on the basis of a Participant's Normal Benefit Amount, as defined in
the following paragraph.

     The Normal Benefit Amount for any Participant shall mean monthly annuity
payments to the Participant, commencing on his Normal Retirement Date, paid in
the Standard Form of


                                         -10-
<PAGE>

Benefit, in an amount equal to the greater of (1) the minimum supplemental
benefit defined in this Section, or (2) the product of the Participant's Average
Monthly Compensation multiplied by the Participant's Target Percentage, such
product being (i) reduced by:

          (a) One-half of the Primary Social Security Benefit to which the
     Participant would be entitled if application were made as of the Normal
     Retirement Date based upon the law in effect when the Normal Benefit Amount
     is being calculated and assuming that the Participant receives no further
     earnings, and

          (b) An amount equal to the monthly benefits that would be paid to the
     Participant under the Midwest Medical Insurance Holding Company 1986
     Pension Plan (or any other qualified Plan(s) to which the Company has
     agreed to make contributions on the Participant's behalf in lieu of the
     Midwest Medical Insurance Holding Company 1986 Pension Plan), if (1) the
     value of the Participant's nonforfeitable benefit under such plan as of the
     distribution commencement date of such benefit (or on the date of the most
     recent valuation of such benefit, if no distributions have been made from
     said plan to the Participant) were projected to his Normal Retirement Date
     assuming a net growth rate from year to year equal to the interest rate
     fixed by the Pension Benefit Guaranty Corporation for valuing immediate
     annuities for single-employer plans terminating as of January 1 of the
     calendar year in which the Normal Benefit Amount is being determined, and
     (ii) such amount were paid in the form of a


                                         -11-
<PAGE>

     straight life annuity for the life of the Participant with monthly payments
     commencing on the Normal Retirement Date, and

          (c)  The amount shown in Schedule B as the Polaris Offset Amount for
      said Participant,
  
and (ii) increased by such amounts, if any, as are determined in the sole 
discretion of the Board.

     For purposes of determining the amount of the monthly annuity that could be
purchased with the Participant's projected accrued benefit under the Midwest
Medical Insurance Holding Company 1986 Pension Plan (or a substitute plan), the
Company shall rely on the annuity amount quoted by the funding agent of the
Pension Plan, if such funding agent offers annuity contracts. If the Pension
Plan has no funding agent, or the funding agent does not offer annuity
contracts, the Company may rely on the annuity amount quoted by any insurance
company or other annuity provider deemed by the Company to be reputable. The
selection of an insurance company or annuity provider shall be final and binding
on all parties.

     The "minimum supplemental benefit" referred to in the second paragraph of
this Section is a monthly annuity payment commencing on the Participant's Normal
Retirement Date, paid in the Standard Form of Benefit, equal to the product of
the Participant's Average Monthly Compensation multiplied by one percent (1%)
for each full year of plan participation completed by the Participant, to a
maximum of 10%. A year of plan participation shall be a twelve-consecutive-month
period measured from the Participant's Entry Date or anniversaries of that date,
subject to the loss of credited years of participation under Section 3.6.

     SECTION 4.2    FORMS OF BENEFIT.  Except as elected otherwise by the
Company in the manner provided herein, benefits under this Plan will be payable
in accordance with the Standard Form of Benefit. By written notice provided to
the Company prior to the effective date of his or


                                         -12-
<PAGE>

her participation in the Plan, a new Participant may elect to receive benefits
in an alternative form from among options selected by the Company, rather than
the Standard Form of Benefit. At the Company's option, such alternative forms of
benefit may include:

          (a)  Monthly annuity payments for the life of the Participant;

          (b)  Monthly annuity payments for the life of the Participant with a
     fixed minimum term of other than ten (10) years;

          (c)  Monthly joint and survivor annuity payments for the lives of the
     Participant and the Participant's spouse; or

          (d)  Monthly joint and survivor annuity payments for the lives of the
     Participant and the Participant's spouse, with a fixed minimum term.

If a Participant elects to receive benefit payments under this Plan in a form
other than the Standard Form of Benefit, the amount of the benefit so provided
shall be actuarially equivalent to the Normal Benefit Amount paid in the
Standard Form of Benefit (based upon the annuity amounts offered by the
insurance company or other annuity provider selected by the Company to provide
the benefit), adjusted in accordance with Sections 4.3 and 4.4. No Participant
shall have any right or option to receive additional current compensation in
lieu of any benefit under this Plan.

     The Beneficiary of a Participant shall receive a monthly death benefit if
(a) the Participant was receiving a benefit under the Plan at the time of his
death, or would have been eligible to receive a benefit had he retired on the
day before his death, and (b) the form of benefit determined under this Section
provides for a survivor benefit or payments for a fixed minimum


                                         -13-
<PAGE>

term that has not expired. Death benefits shall commence as of the first day of
the first calendar month beginning on or after the date of the Participant's
death.

     SECTION 4.3    VALUE OF BENEFITS UPON NORMAL RETIREMENT DATE.  If a
Participant retires or otherwise terminates his employment with the Company for
any reason, including death or disability, on or after his Normal Retirement
Date, the Participant or his Beneficiary shall be entitled to receive benefits
under the Plan equivalent to the Normal Benefit Amount multiplied by the
Participant's vesting percentage. The vesting percentage for a Participant is
the Participant's Years of Service (including fractional years) multiplied by
10%. The vesting percentage shall never be greater than 100%. Benefits under
this Section shall commence as of the first day of the first calendar month
beginning on or after the date of termination.

     SECTION 4.4    VALUE OF BENEFITS UPON EARLY RETIREMENT.  If a Participant
retires or otherwise terminates employment with the Company for any reason,
including death or disability, prior to his Normal Retirement Date but after
reaching his Early Retirement Date, he or his Beneficiary shall be entitled to
receive an early retirement benefit under this Plan commencing on the first day
of the first calendar month beginning on or after the date of termination. His
early retirement benefit shall be the benefit he would have received under
Section 4.3 had he retired on his Normal Retirement Date, assuming the
Participant's Years of Service and Average Monthly Compensation are the same as
on his actual termination date, reduced by five-twelfths of one percent (5/12%)
for each complete calendar month, if any, by which the Participant's benefit
commencement date precedes his Normal Retirement Date.

     SECTION 4.5    EFFECT OF INCOMPETENCY.  Every Participant receiving or
entitled to receive benefits under this Plan shall be presumed mentally
competent until and unless the Company receives written notice in a form and
manner acceptable to the Company to the effect that such


                                         -14-
<PAGE>

Participant is incompetent and that a guardian, conservator, or other person
legally vested with the care of the Participant's estate has been appointed.
Such notice shall also specify the name, address, and telephone number of such
guardian, conservator, or other person. Upon receipt of such notice the Company
may, but shall not be required to, direct benefit payments due such Participant
to such guardian, conservator, or other person legally vested with the care of
the Participant's estate.

     SECTION 4.6    NO INTEREST PAYABLE.  No Participant shall have the right to
receive interest on any portion of the total benefits under this Plan that
remains unpaid from time to time.


                          ARTICLE 5. BENEFICIARY DESIGNATION

     SECTION 5.1    DESIGNATION BY PARTICIPANT.  Each Participant may designate
primary and contingent Beneficiaries for any benefits that may remain payable
under the Plan at the time of the Participant's death. Such Beneficiaries may be
individuals or trusts for the benefit of individuals, except that the Company,
in its discretion, may require the designation of a single party to whom benefit
payments may be made (as a matter of convenience and without prejudice to the
rights of others) where a Participant's beneficiary designation would otherwise
require that benefit payments be allocated among four (4) or more recipients. A
beneficiary designation by a Participant shall be in writing in a form
acceptable to the Company and shall only be effective upon delivery to the
Company prior to the Participant's death. A beneficiary designation may be
revoked by a Participant at any time by delivering to the Company either written
notice of revocation or a new beneficiary designation form. The beneficiary
designation form last delivered to the Company prior to the death of a
Participant shall control.


                                         -15-
<PAGE>

     SECTION 5.2    FAILURE TO DESIGNATE BENEFICIARY.  In the event there is no
beneficiary designation on file with the Company or all Beneficiaries designated
by a Participant have predeceased the Participant, any benefits remaining
payable under this Plan at the time of the death of the Participant shall be
paid to the Participant's spouse, if living; if the Participant does not leave a
surviving spouse, to the Participant's issue by right of representation; or, if
there are no such issue then living, to the Participant's estate.

     SECTION 5.3    DEATH OF BENEFICIARY.  Any portion of a Participant's
benefit payable to a Beneficiary shall be paid to the Beneficiary's estate,
unless the Beneficiary has previously provided the Company with a written
directive naming a successor Beneficiary, in which case such unpaid benefits
shall be paid to such named successor Beneficiary.


                                  ARTICLE 6. FUNDING

     SECTION 6.1    SOURCE OF BENEFITS.  All benefits under this Plan shall be
paid when due by the Company out of its assets. The Company may, but shall have
no obligation to, make such advance provision for the payment of such benefits
as the Board of Directors may from time to time consider appropriate.

     SECTION 6.2    NO CLAIM ON SPECIFIC ASSETS.  In the event the Company shall
determine in its discretion to make advance provisions for any portion of its
obligations under the Plan, any amounts so set aside shall nonetheless remain
the exclusive property of the Company and shall in no event be deemed to
constitute a segregated fund, whether in trust or otherwise, for the current
benefit of any Participant. No Participant shall be deemed to have, by virtue of
being a Participant in the Plan, any claim on any specific assets of the Company
such that the Participant would be subject to income taxation on his benefits
under this Plan prior to distribution and the


                                         -16-
<PAGE>

rights of Participants and Beneficiaries to benefits to which they are otherwise
entitled under the Plan shall be those of a general creditor of the Company.


                        ARTICLE 7. ADMINISTRATION AND EXPENSES

     SECTION 7.1    ADMINISTRATION. The Plan shall be administered by the
Committee.

     SECTION 7.2    POWERS OF COMMITTEE.  The Committee shall have all powers
necessary to administer the Plan, including, without limitation, powers:

          (a)  to interpret the provisions of the Plan;

          (b)  to establish and revise the method of accounting for the Plan and
     to maintain the accounts;

          (c)  to establish rules for the administration of the Plan and to
     prescribe any forms required to administer the Plan; and

          (d)  to determine the rights of Participants and Beneficiaries.

     SECTION 7.3    CLAIMS PROCEDURE.  The Committee shall notify a Participant
in writing within ninety (90) days of his written application for benefits of
his eligibility or non-eligibility for benefits under the Plan. If the Committee
determines that a Participant is not eligible for benefits or full benefits, the
notice shall set forth (1) the specific reasons for such denial, (2) a specific
reference to the provision of the Plan on which the denial is based, (3) a
description of any additional information or material necessary for the claimant
to perfect his claim, and a description of why it is needed, and (4) an
explanation of the Plan's claims review procedure and other appropriate
information as to the steps to be taken if the Participant wishes to have his
claim reviewed. If the Committee determines that there are special circumstances
requiring additional time to make a decision, the Committee shall notify the
Participant of the special


                                         -17-
<PAGE>

circumstances and the date by which a decision is expected to be made, and may
extend the time for up to an additional 90-day period. If a Participant is
determined by the Committee to be not eligible for benefits, or if the
Participant believes that he is entitled to greater or different benefits, he
shall have the opportunity to have his claim reviewed by the Committee by filing
a petition for review with the Committee within sixty (60) days after receipt by
him of the notice issued by the Committee. Said petition shall state the
specific reasons the Participant believes he is entitled to benefits or greater
or different benefits. Within sixty (60) days after receipt by the Committee of
said petition, the Committee shall afford the Participant (and his counsel, if
any) an opportunity to present his position to the Committee orally or in
writing, and said Participant (or his counsel) shall have the right to review
the pertinent documents, and the Committee shall notify the Participant of its
decision in writing within said sixty (60) day period, stating specifically the
basis of said decision written in a manner calculated to be understood by the
Participant and the specific provisions of the Plan on which the decision is
based. If, because of the need for a hearing, the sixty (60) day period is not
sufficient, the decision may be deferred for up to another sixty (60) day period
at the election of the Committee, but notice of this deferral shall be given to
the Participant.

     In the event of the death of a Participant, the same procedure shall be
applicable to his Beneficiaries.

     SECTION 7.4    DELEGATION.  The Committee shall have the power to delegate
specific duties and responsibilities to officers or other employees of the
Company or other individuals or entities. Any delegation by the Committee may
allow further delegations by the individual or entity to whom the delegation is
made. Any delegation may be rescinded by the Committee at any time. Each person
or entity to whom a duty or responsibility has been delegated shall be


                                         -18-
<PAGE>

responsible for the exercise of such duty or responsibility and shall not be
responsible for any act or failure to act of any other person or entity.

     SECTION 7.5    REPORTS AND RECORDS.  The Company, the Committee and those
to whom the Committee has delegated duties under the Plan shall keep records of
all their proceedings and actions and shall maintain books of account, records,
and other data as shall be necessary for the proper administration of the Plan
and for compliance with applicable law.

     SECTION 7.6    EXPENSES.  The administrative costs of the Plan shall be
borne solely by the Company. No contributions from Participants, whether by way
of salary reduction, deferral of bonuses or salary increases, or any other
means, will be required or permitted.


                        ARTICLE 8. AMENDMENTS AND TERMINATION

     SECTION 8.1    AMENDMENTS.  The Company, by action of the Board, may amend
the Plan, in whole or in part, at any time and from time to time. Any such
amendment shall be filed with the Plan documents. No amendment, however, may be
effective to eliminate or reduce the benefits of any retired Participant or the
Beneficiary of any deceased Participant then eligible for benefits or the
benefits, if any, which any active Participant would be entitled to receive if
such Participant retired after the occurrence of an event specified in Section
9.1 immediately before the effective date of such amendment.

     SECTION 8.2    TERMINATION.  The Company expects the Plan to be permanent,
but necessarily must, and hereby does, reserve the right to terminate the Plan
at any time by action of the Board. Any such termination shall not operate to
eliminate or reduce benefits of any retired Participant or the Beneficiary of
any deceased Participant then eligible for benefits, and active Participants
shall become vested in their accrued benefits to the extent and in the manner


                                         -19-
<PAGE>

provided in Article 9 as of the effective date of such termination. Termination
of the Plan will not accelerate the distribution of benefits. Benefits shall be
paid in accordance with the terms of the Plan as in existence at the time of its
termination.


                    ARTICLE 9. ACCELERATION OF VESTING AND ACCRUAL

     SECTION 9.1    ACCELERATED VESTING AND ACCRUAL.  Upon the occurrence of one
of the events specified in this Section, a Participant, notwithstanding the
provisions of Article 4, shall be credited with three additional Years of
Service for purposes of vesting. The credited service awarded under the
preceding sentence shall be in addition to any Years of Service credited before
or after the event. The occurrence of an event specified in this Section will
not cause any benefit to be immediately distributable.

     The events referred to in the preceding paragraph, which will cause the
accelerated vesting of benefits, shall include the following:

          (a)  The Company terminates the Plan.

          (b)  A "Change in Control" as defined in Section 9.3.

          (c)  The voluntary decision by the Company to discontinue its present
     operations (including the adoption of a plan of liquidation).

          (d)  The enactment of legislation providing that the insurance
     activities of the Company shall be provided by the State of Minnesota or
     the Federal government.

     In the event that the Company terminates the Plan or a Participant's
employment is terminated after the occurrence of an event described in (b), (c)
or (d) above (regardless whether


                                         -20-
<PAGE>

the Participant has reached his Early Retirement or Normal Retirement Date),
each affected Participant shall have a contingent vested interest in the benefit
described in Section 4.3 of the Plan, taking into account the additional Years
of Service awarded pursuant to this Section. Vesting of this benefit is
contingent upon the Participant's attaining Age 55 or liquidation of the Company
while solvent, whichever occurs first. Service after termination of the Plan
shall be disregarded and no additional vesting shall be granted after
termination of employment. The Average Monthly Compensation used to determine
this benefit shall be calculated as of the Normal Retirement Date assuming that
the Participant continued employment until his Normal Retirement Date at the
same rate of compensation that he was receiving on the day of the Plan
termination or his termination of employment, whichever is earlier.

     A benefit described in this Section shall be payable in the Standard Form
of Benefit commencing on the Participant's Normal Retirement Date. If the
Participant dies after attaining Age 55 but before payments commence under this
Article, benefits shall commence to the Participant's Beneficiary on the 60th
day following the Participant's death in accordance with the Standard Form of
Benefit, including payments retroactive to the first day of the first month
beginning on or after the date of the Participant's death, and in an amount
which is actuarially equivalent to the Standard Form of Benefit commencing on
the Normal Retirement Date. If the 60th day after the Participant's death falls
on a weekend or holiday, the initial payment shall be made on the first business
day following the 60th day.

     SECTION 9.2    EARLY DISTRIBUTION.  Upon a determination (as defined in
Section 1313 of the Code) that any amounts are includible in a Participant's
gross income as a result of benefits to be provided under this Plan, but prior
to the receipt of such benefits, a Participant shall be entitled to receive an
accelerated, lump sum distribution of the includible amounts. The


                                         -21-
<PAGE>

accelerated benefit shall be paid in a single payment on the 60th day after the
date of the determination. Any such distribution shall be deemed a benefit paid
pursuant to the Plan and shall be offset, without interest, in determining the
amount of any subsequent distribution to the Participant pursuant to the Plan.
If the 60th day after the date of the determination falls on a weekend or
holiday, the payment shall be made on the first business day following the 60th
day.

     SECTION 9.3    CHANGE IN CONTROL.  A Change in Control shall occur if:

          (a)  Any "person" or "group" (within the meaning of Sections 13(d) and
     14(d)(2) of the Securities Exchange Act of 1934, as amended (the "Act"))
     becomes the "beneficial owner" (as defined in Rule 13d under the Act) of
     more than 50 percent of the then outstanding voting stock of Midwest
     Medical Insurance Holding Company, otherwise than through a transaction
     arranged by, or consummated with the prior approval of, the Board of
     Directors of Midwest Medical Insurance Holding Company ("MMIHC Board"); or

          (b)  During any period of two consecutive years, individuals who at
     the beginning of such period constitute the MMIHC Board (and any new
     director whose election by the MMIHC Board or whose nomination for election
     by the stockholders of Midwest Medical Insurance Holding Company was
     approved by a vote of at least 2/3rds of the directors then still in office
     who either were directors at the beginning of such period or whose election
     or nomination for election was previously so approved) cease for any reason
     to constitute a majority thereof.

                              ARTICLE 10. MISCELLANEOUS

     SECTION 10.1   NO GUARANTY OF EMPLOYMENT.  Neither the adoption and
maintenance of the Plan nor the execution by the Company of a participation
agreement with any employee shall be deemed to be a contract of employment
between the Company and any Participant. Nothing contained herein shall give any
Participant the right to be retained in the employ of the Company or to
interfere with the right of the Company to discharge any Participant at any
time, nor shall it give the Company the right to require any Participant to
remain in its employ or to interfere with the Participant's right to terminate
his employment at any time.

     SECTION 10.2   RELEASE.  Any payment of benefits to or for the benefit of a
Participant or a Participant's Beneficiaries that is made in good faith by the
Company in accordance with the Company's interpretation of its obligations
hereunder, shall be in full satisfaction of all claims against the Company for
benefits under this Plan to the extent of such payment.

     SECTION 10.3   NOTICES.  Any notice permitted or required under the Plan
shall be in writing and shall be hand delivered or sent, postage prepaid,
certified or registered mail with return receipt requested, to the principal
office of the Company, if to the Company, or to the address last shown on the
records of the Company, if to a Participant or Beneficiary. Any such notice
shall be effective as of the date of hand delivery or mailing.

     SECTION 10.4   NON-ALIENATION.  No benefit payable at any time under this
Plan shall be subject in any manner to alienation, sale, transfer, assignment,
pledge, levy, attachment, or encumbrance of any kind.

     SECTION 10.5   CAPTIONS.  Article and section headings and captions are
provided for purposes of reference and convenience only and shall not be relied
upon in any way to construe, define, modify, limit, or extend the scope of any
provision of the Plan.
