                  Section 1.1 Defined Terms. As used in this Agreement the
following terms shall have the following respective meanings (and such meanings
shall be equally applicable to both the singular and plural form of the terms

corporation.

                  "Adjusted Capital": The Adjusted Capital of ACIC (as such
formula is determined by the NAIC). In the event that there is a conflict
between the Adjusted Capital formulas adopted by the NAIC and the Insurance
Regulatory Authority, the calculation adopted by the Insurance Regulatory
Authority shall govern.

                  "Adjusted Eurodollar Rate": With respect to each Interest
Period applicable to a Eurodollar Rate Advance, the rate (rounded upward, if
necessary, to the next one hundredth of one percent) determined by dividing the
Eurodollar Rate for such Interest Period by 1.00 minus the Eurodollar Reserve
Percentage.

                  "Advance": Any portion of the outstanding Loans as to which
one of the available interest rate options and, if pertinent, an Interest
Period, is applicable. An Advance may be a Eurodollar Rate Advance, a Negotiated
Rate Advance or a Reference Rate Advance.

                  "Affiliate": When used with reference to any Person, (a) each
Person that, directly or indirectly, controls, is controlled by or is under
common control with, the Person referred to, (b) each Person which beneficially
owns or holds, directly or indirectly, five percent or more of any class of
voting stock of the Person referred to (or if the Person referred to is not a
corporation, five percent or more of the equity interest), (c) each Person, five
percent or more of the voting stock (or if such Person is not a corporation,
five percent or more of the equity interest) of which is beneficially owned or
held, directly or indirectly, by the Person referred to, and (d) each of such
Person's officers, directors, joint venturers and partners. The term control
(including the terms "controlled by" and "under common control with") means the
possession, directly, of the power to direct or cause the direction of the
management and policies of the Person in question.

promulgated by the NAIC for Property and Casualty Insurance Company Annual
Statements. If such format is changed in future years so that different
information is contained in such items or they no longer exist, it is understood
that the reference is to information consistent with that reported in the
referenced item in the 1999 Annual Statement of ACIC.

                  "Applicable Insurance Code": As to ACIC, the insurance code of
the State of Minnesota and any successor statute of similar import, together
with the regulations thereunder, as amended or otherwise modified and in effect
from time to time. References to sections of the Applicable Insurance Code shall

Advances in effect at all times shall be zero percent (0.00%). The Applicable
Margin for Eurodollar Rate Advances in effect during the period beginning on the

in effect for the three months period beginning March 1, 2001 and ending May 31,
2001 and for each succeeding three-months period consisting of the months of

Note payable to the order of the Bank in a principal amount equal to the Term
Commitment Amount. The Bank shall enter in its ledgers and records the amount of
each Loan, the various Advances made, converted or continued and the payments
made thereon, and the Bank is authorized by the Borrower to enter on a schedule
attached to the applicable Note a record of such Loans, Advances and payments;
provided, however, that the failure by the Bank to make any such entry or any
error in making such entry shall not limit or otherwise affect the obligation of

conversion of any Advances and such notice must be given so as to be received by
the Bank not later than 12:00 noon (Minneapolis time) two Eurodollar Business
Days prior to requested date of conversion or continuation in the case of the
continuation of, or conversion to, Eurodollar Rate Advances and not later than

Negotiated Rate Advances within the time required by this Section, such Advances
shall, on the last day of the Interest Period applicable thereto, automatically
be converted into Reference Rate Advances of the same principal amount.

         Interest Period, or

                  (b) the Adjusted Eurodollar Rate, as the case may be, will not
         adequately and fairly reflect the cost to the Bank of funding or
         maintaining Eurodollar Rate Advances for such Interest Period,

the Bank shall forthwith give notice to the Borrower of such determination,
whereupon the obligation of the Bank to make or continue, or to convert any
Advances to, Eurodollar Rate Advances shall be suspended until the Bank notifies
the Borrower that the circumstances giving rise to such suspension no longer
exist. While any such suspension continues, all further Advances by the Bank
shall be made as Reference Rate Advances or Negotiated Rate Advances. No such
suspension shall affect the interest rate then in effect during the applicable
Interest Period for any Eurodollar Rate Advance outstanding at the time such
suspension is imposed.

                  Section 2.15 Increased Cost. If any Regulatory Change:

                           (a) shall subject the Bank to any tax, duty or other
         charge with respect to its Fixed Rate Advances, the Notes or its
         obligation to make Fixed Rate Advances or shall change the basis of
         taxation of payment to the Bank of the principal of or interest on its
         Fixed Rate Advances or any other amounts due under this Agreement in
         respect of Fixed Rate Advances or its obligation to make Fixed Rate
         Advances (except for changes in the rate of tax on the overall net
         income of the Bank imposed by the jurisdiction in which the Bank's
         principal office is located); or

                           (b) shall impose, modify or deem applicable any
         reserve, special deposit or similar requirement (including, without
         limitation, any such requirement imposed by the Board, but excluding
         with respect to any Eurodollar Rate Advance any such requirement to the
         extent included in calculating the applicable Adjusted Eurodollar Rate)
         against assets of, deposits with or for the account of, or credit
         extended by, the Bank or shall impose on the Bank or on the United
         States market for certificates of deposit or the interbank Eurodollar
         market any other condition affecting Fixed Rate Advances, the Notes or
         its obligation to make Fixed Rate Advances;

and the result of any of the foregoing is to increase the cost to the Bank of
making or maintaining any Fixed Rate Advance, or to reduce the amount of any sum
received or receivable by the Bank under this Agreement or under the Notes,
then, and in each such case, upon one hundred twenty (120) days notice to the
Borrower from the Bank of the nature of such Regulatory Change, the Borrower
shall pay to the Bank such additional amount or amounts as will compensate the
Bank for such increased cost or reduction for the period from and after the one
hundred twentieth (120th) day after such notice is given.

                                      -17-

A certificate of the Bank claiming compensation under this Section, setting
forth the additional amount or amounts to be paid to it hereunder and stating in
reasonable detail the basis for the charge and the method of computation, shall
be conclusive in the absence of manifest error. In determining such amount, the
Bank may use any reasonable averaging and attribution methods. Failure on the
part of the Bank to demand compensation for any increased costs or reduction in
amounts received or receivable with respect to any Interest Period shall not
constitute a waiver of the Bank's rights to demand compensation for any
increased costs or reduction in amounts received or receivable in any subsequent
Interest Period.

                  Section 2.16 Illegality. If any Regulatory Change shall make
it unlawful or impossible for the Bank to make, maintain or fund any Eurodollar
Rate Advances, the Bank shall notify the Borrower, whereupon the obligation of
the Bank to make or continue, or to convert any Advances to Eurodollar Rate
Advances shall be suspended until the Bank notifies the Borrower that the
circumstances giving rise to such suspension no longer exist. If the Bank
determines that it may not lawfully continue to maintain any Eurodollar Rate
Advances to the end of the applicable Interest Periods, all of the affected
Advances shall be automatically converted to Reference Rate Advances as of the
date of the Bank's notice, and upon such conversion the Borrower shall indemnify
the Bank in accordance with Section 2.18.

                  Section 2.17 Capital Adequacy. In the event that any
Regulatory Change reduces or shall have the effect of reducing the rate of
return on the Bank's capital or the capital of its parent corporation (by an
amount the Bank deems material) as a consequence of its Revolving Commitment
and/or Advances to a level below that which the Bank or its parent corporation
could have achieved but for such Regulatory Change (taking into account the
Bank's policies and the policies of its parent corporation with respect to
capital adequacy), then, in each such case, upon one hundred twenty (120) days
notice to the Borrower from the Bank, the Borrower shall pay to the Bank
additional amounts sufficient to compensate the Bank or its parent corporation
for such reduction for the period from and after the one hundred twentieth
(120th) day after such notice is given. Any determination by the Bank under this
Section and any certificate as to the amount of such reduction given to the
Borrower by the Bank shall be final, conclusive and binding for all purposes,
absent manifest error.

                  Section 2.18 Funding Losses; Eurodollar Rate Advances. The
Borrower shall compensate the Bank, upon its written request, for all losses,
expenses and liabilities (including any interest paid by the Bank to lenders of
funds borrowed by it to make or carry Eurodollar Rate Advances to the extent not
recovered by the Bank in connection with the reemployment of such funds and
including loss of anticipated profits) which the Bank may sustain: (i) if for
any reason, other than a default by the Bank, a funding of a Eurodollar Rate
Advance does not occur on the date specified therefor in the Borrower's request
or notice as to such Advance under Section 2.2 or 2.5, or (ii) if, for whatever
reason (including, but not limited to, mandatory and optional prepayment and
acceleration of the maturity of Advances following an Event of Default), any
prepayment or repayment of a Eurodollar Rate Advance, or a conversion pursuant
to Section 2.16, occurs on any day other than the last day of the Interest
Period applicable thereto. The Bank's request for compensation shall set forth
the basis for the amount requested and shall be final, conclusive and binding,
absent manifest error.

                  Section 2.19 Discretion of Bank as to Manner of Funding. The
Bank shall be entitled to fund and maintain its funding of Eurodollar Rate
Advances in any manner it may elect, it being understood, however, that for the
purposes of this Agreement all determinations hereunder (including, but not
limited to, determinations under Section 2.18) shall be made as if the Bank had
actually funded and maintained each Eurodollar Rate Advances during the Interest
Period for such Advance through the purchase of deposits having a maturity
corresponding to the last day of the Interest Period and bearing an interest
rate equal to the Eurodollar Rate for such Interest Period.

                  Section 2.20 Negotiated Rate Prepayment Indemnity. The
Borrower acknowledges and agrees as follows: (i) the Borrower has no right to
repay any Negotiated Rate Advance without the Bank's consent, which the Bank
will grant only on the terms and subject to the conditions hereinafter provided;
(ii) the Bank will be harmed by reason of any prepayment of any Negotiated Rate
Advance at a time when interest rates have declined below the levels prevailing
on the date a Loan (or portion thereof) was made as or converted to a Negotiated
Rate Advance because any reinvestment of the prepaid funds at the lower rates
prevailing on the date of prepayment will produce a lower return to the Bank;
(iii) there is no readily available index of rates payable on loans such as that
from the Bank to the Borrower, nor any assurance that the Bank could replace the
loan with a similar loan; and (iv) changes in the yields on U.S. government
securities provide a reasonable approximation for changes in interest rates
generally. To induce the Bank to agree to accept voluntary prepayments, to the
extent permitted by applicable law, the Borrower agrees to pay to the Bank a
prepayment indemnity as described in this Section upon any prepayment, whether
voluntary or involuntary, and agrees to all of the other terms of prepayment
herein. For purposes of this section, the following terms shall have the
meanings given below:

                  "Average Maturity Period": as of any prepayment date, the
weighted average time period computed by multiplying the dollar amount of each
installment or payment of principal prepaid by the number of days from such
prepayment date until the earlier of the scheduled maturity of that installment
or payment or the next Interest Change Date (if any), adding together the
resulting products and dividing the resulting sum by the total dollar amount of
principal being prepaid.

                  "Government Yield": as to any date of determination, the
annual yield (converted as necessary to the equivalent semi-annual compound
rate) on a U.S. Treasury security having a maturity date closest to the date
computed by adding the Average Maturity Period to the date of prepayment, as
published in The Wall Street Journal (or, if not so published, as determined by
the Bank based on quotations by secondary market dealers selected by the Bank).
"U.S. Treasury securities" means actively traded U.S. Treasury bonds, bills and
notes. If more than one issue of U.S. Treasury securities is scheduled to mature
at or about the time of such computed date, then to the extent possible the U.S.
Treasury security trading closest to its par value will be chosen as the basis
of the Government Yield.

                  "Interest Change Date": the date of any regularly scheduled
adjustment in the interest rate on the Notes.

                                      -19-

<PAGE>   20

                  "Interest Differential": as of any prepayment date, (i) the
applicable Negotiated Rate as in affect on the date of prepayment minus (ii) the
sum of (A) the Government Yield as of the date of prepayment, plus (B) the
Issuance Spread.

                  "Issuance Spread": thirty-hundredths of one percent (0.30%)
per annum.

                  With the prior written consent of the Bank, Negotiated Rate
Advances may be prepaid in whole or in part at any time, with partial
prepayments in the amount of $100,000 or an integral multiple thereof. Any
partial prepayments shall be applied to installments due under the applicable
Negotiated Rate Advance in the inverse order of their maturity (if such
Negotiated Rate Advance is payable in installments). If at the time of any
prepayment (whether voluntary or involuntary, and specifically including but not
limited to any payment prior to scheduled maturity following acceleration of the
Loans), the Interest Differential shall exceed zero, such prepayment shall be
accompanied, to the extent permitted by law, by payment of a prepayment
indemnity. The amount of the prepayment indemnity shall equal the present value
(determined by Bank using the Government Yield as of the date of prepayment as
the discount factor) on the prepayment date of a stream of equal monthly
payments in number equal to the number of whole months (using a thirty-day
month) in the Average Maturity Period. The amount of each such monthly payment
shall equal the quotient obtained by dividing (a) the product of the amount
prepaid, times the Interest Differential, times a fraction, the numerator of
which is the number of days in the Average Maturity Period and the denominator
of which is 360, by (b) the number of whole months (using a thirty-day month) in
the Average Maturity Period.

                  Section 2.21 Extension of Revolving Commitment Ending Date. If
the Borrower by written notice given to the Bank not more than 60 days prior to
the Revolving Commitment Ending Date requests in writing an extension of the
Revolving Commitment Ending Date for an additional period of time and if the
Bank, in its sole and absolute discretion and based on such review of the
Borrower's financial performance and condition and such other factors as the
Bank considers relevant (which may include, without limitation, future loan
policies and other policies adopted by the Bank unrelated to the Borrower's
financial condition), consents in writing to such extension within thirty (30)
days of receipt of the Borrower's request hereunder, then the Revolving
Commitment Ending Date shall be extended for such additional period of time, and
in such extended period the Borrower may repeat its request within the same time
limit and if the Bank consents the Revolving Commitment Ending Date shall be
further extended for an additional period, and so on from time to time. In the
case of any such extension, the "Revolving Commitment Ending Date" shall be the
last day of the period to which such extension has been granted. The Bank shall
not be under any obligation or commitment to extend the Revolving Commitment
Ending Date, and no such obligation or commitment on the part of the Bank should
be inferred from the provisions of this Section.

                                   ARTICLE IV

                         REPRESENTATIONS AND WARRANTIES

                  To induce the Bank to enter into this Agreement and to make
Loans hereunder, the Borrower represents and warrants to the Bank:

                  Section 4.1 Organization, Standing, Etc. The Borrower is a
corporation duly incorporated and validly existing and in good standing under
the laws of the jurisdiction of its incorporation and has all requisite
corporate power and authority to carry on its business as now conducted, to
enter into this Agreement and to issue the Notes and to perform its obligations
under the Loan Documents. Each Subsidiary is a corporation duly incorporated and
validly existing and in good standing under the laws of the jurisdiction of its
incorporation and has all requisite corporate power and authority to carry on
its business as now conducted. Each of the Borrower and the Subsidiaries (a)
holds all certificates of authority, licenses and permits necessary to carry on
its business as presently conducted in each jurisdiction in which it is carrying
on such business, except where the failure to hold such certificates, licenses
or permits would not have a material adverse effect on the business, operations,
property, assets or condition, financial or otherwise, of the Borrower and the
Subsidiaries taken as a whole, and (b) is duly qualified and in good standing as
a foreign corporation in each jurisdiction in which the character of the
properties owned, leased or operated by it or the business conducted by it makes
such qualification necessary and the failure so to qualify would permanently
preclude the Borrower or such Subsidiary from enforcing its rights with respect
to any assets or expose the Borrower or such Subsidiary to any liability, which
in either case would be material to the Borrower and the Subsidiaries taken as a
whole.

                  Section 4.2 Authorization and Validity. The execution,
delivery and performance by the Borrower of the Loan Documents have been duly
authorized by all necessary corporate action by the Borrower, and this Agreement
constitutes, and the Notes and other Loan Documents when executed will
constitute, the legal, valid and binding obligations of the Borrower,
enforceable against the Borrower in accordance with their respective terms,
subject to limitations as to enforceability which might result from bankruptcy,
insolvency, moratorium and other similar laws affecting creditors' rights
generally and subject to limitations on the availability of equitable remedies.

                  Section 4.3 No Conflict; No Default. The execution, delivery
and performance by the Borrower of the Loan Documents will not (a) violate any
provision of any law, statute, rule or regulation or any order, writ, judgment,
injunction, decree, determination or award of any court, governmental agency or
arbitrator presently in effect having applicability to the Borrower, (b) violate
or contravene any provision of the Articles of Incorporation or bylaws of the
Borrower, or (c) result in a breach of or constitute a default under any
indenture, loan or credit agreement or any other agreement, lease or instrument
to which the Borrower is a party or by which it or any of its properties may be
bound or result in the creation of any Lien thereunder. Neither the Borrower nor
any Subsidiary is in default under or in violation of any such law, statute,
rule or regulation, order, writ, judgment, injunction, decree, determination or
award or any such indenture, loan or credit agreement or other agreement,

                                      -23-

<PAGE>   24

lease or instrument in any case in which the consequences of such default or
violation could have a material adverse effect on the business, operations,
properties, assets or condition (financial or otherwise) of the Borrower and its
Subsidiaries taken as a whole.

                  Section 4.4 Government Consent. No order, consent, approval,
license, authorization or validation of, or filing, recording or registration
with, or exemption by, any governmental or public body or authority is required
on the part of the Borrower to authorize, or is required in connection with the
execution, delivery and performance of, or the legality, validity, binding
effect or enforceability of, the Loan Documents, except for any necessary filing
or recordation of or with respect to any of the Security Documents.

                  Section 4.5 Financial Statements and Condition. The Borrower's
audited consolidated financial statements as at December 31, 1999, as heretofore
furnished to the Bank, have been prepared in accordance with GAAP on a
consistent basis and fairly present the financial condition of the Borrower and
its Subsidiaries as at such dates and the results of their operations and
changes in financial position for the respective periods then ended. As of the
dates of such financial statements, neither the Borrower nor any Subsidiary had
any material obligation, contingent liability, liability for taxes or long-term
lease obligation which is not reflected in such financial statements or in the
notes thereto. Since December 31, 1999, there has been no material adverse
change in the business, operations, property, assets or condition, financial or
otherwise, of the Borrower and its Subsidiaries taken as a whole.

                  Section 4.6 Litigation. There are no actions, suits or
proceedings pending or, to the knowledge of the Borrower, threatened against or
affecting the Borrower or any Subsidiary or any of their properties before any
court or arbitrator, or any governmental department, board, agency or other
instrumentality which, if determined adversely to the Borrower or such
Subsidiary, would have a material adverse effect on the business, operations,
property or condition (financial or otherwise) of the Borrower and the
Subsidiaries taken as a whole or on the ability of the Borrower or any
Subsidiary to perform its obligations under the Loan Documents.

                  Section 4.7 Environmental, Health and Safety Laws. There does
not exist any violation by the Borrower or any Subsidiary of any applicable
federal, state or local law, rule or regulation or order of any government,
governmental department, board, agency or other instrumentality relating to
environmental, pollution, health or safety matters which will or threatens to
impose a material liability on the Borrower or a Subsidiary or which would
require a material expenditure by the Borrower or such Subsidiary to cure.
Neither the Borrower nor any Subsidiary has received any notice to the effect
that any part of its operations or properties is not in material compliance with
any such law, rule, regulation or order or notice that it or its property is the
subject of any governmental investigation evaluating whether any remedial action
is needed to respond to any release of any toxic or hazardous waste or substance
into the environment, which noncompliance or remedial action could reasonably be
expected to have a material adverse effect on the business, operations,
properties, assets or condition (financial or otherwise) of the Borrower and its
Subsidiaries taken as a whole. The Borrower does not have knowledge that it or
its property or any Subsidiary or

                                      -24-

<PAGE>   25

the property of any Subsidiary will become subject to environmental laws or
regulations during the term of this Agreement, compliance with which could
reasonably be expected to require Capital Expenditures which would have a
material adverse effect on the business, operations, properties, assets or
condition (financial or otherwise) of the Borrower and its Subsidiaries taken as
a whole.

                  Section 4.8 ERISA. Each Plan is in substantial compliance with
all applicable requirements of ERISA and the Code and with all material
applicable rulings and regulations issued under the provisions of ERISA and the
Code setting forth those requirements. No Reportable Event has occurred and is
continuing with respect to any Plan. All of the minimum funding standards
applicable to such Plans have been satisfied and there exists no event or
condition which would reasonably be expected to result in the institution of
proceedings to terminate any Plan under Section 4042 of ERISA. With respect to
each Plan subject to Title IV of ERISA, as of the most recent valuation date for
such Plan, the present value (determined on the basis of reasonable assumptions
employed by the independent actuary for such Plan and previously furnished in
writing to the Bank) of such Plan's projected benefit obligations did not exceed
the fair market value of such Plan's assets.

                  Section 4.9 Federal Reserve Regulations. Neither the Borrower
nor any Subsidiary is engaged principally or as one of its important activities
in the business of extending credit for the purpose of purchasing or carrying
margin stock (as defined in Regulation U of the Board). The value of all margin
stock owned by the Borrower does not constitute more than 25% of the value of
the assets of the Borrower.

                  Section 4.10 Title to Property; Leases; Liens; Subordination.
Each of the Borrower and the Subsidiaries has (a) good and marketable title to
its real properties and (b) good and sufficient title to, or valid, subsisting
and enforceable leasehold interest in, its other material properties, including
all real properties, other properties and assets, referred to as owned by the
Borrower and its Subsidiaries in the most recent financial statement referred to
in Section 4.5 (other than property disposed of since the date of such financial
statements in the ordinary course of business). None of such properties is
subject to a Lien, except as allowed under Section 6.11. The Borrower has not
subordinated any of its rights under any obligation owing to it to the rights of
any other person.

                  Section 4.11 Taxes. Each of the Borrower and the Subsidiaries
has filed all federal, state and local tax returns required to be filed and has
paid or made provision for the payment of all taxes due and payable pursuant to
such returns and pursuant to any assessments made against it or any of its
property and all other taxes, fees and other charges imposed on it or any of its
property by any governmental authority (other than taxes, fees or charges the
amount or validity of which is currently being contested in good faith by
appropriate proceedings and with respect to which reserves in accordance with
GAAP have been provided on the books of the Borrower). No tax Liens have been
filed and no material claims are being asserted with respect to any such taxes,
fees or charges. The charges, accruals and reserves on the books of the Borrower
in respect of taxes and other governmental charges are adequate and the Borrower
knows of no proposed material tax assessment against it or any Subsidiary or any
basis therefor.

Subsidiaries possesses or has the right to use all of the patents, trademarks,
trade names, service marks and copyrights, and applications therefor, and all
technology, know-how, processes, methods and designs used in or necessary for
the conduct of its business, without known conflict with the rights of others.

                  Section 4.13 Burdensome Restrictions. Neither the Borrower nor
any Subsidiary is a party to or otherwise bound by any indenture, loan or credit
agreement or any lease or other agreement or instrument or subject to any
charter, corporate or partnership restriction which would foreseeably have a
material adverse effect on the business, properties, assets, operations or
condition (financial or otherwise) of the Borrower or such Subsidiary or on the
ability of the Borrower or any Subsidiary to carry out its obligations under any
Loan Document.

                  Section 4.14 Force Majeure. Since the date of the most recent
financial statement referred to in Section 4.5, the business, properties and
other assets of the Borrower and the Subsidiaries have not been materially and
adversely affected in any way as the result of any fire or other casualty,
strike, lockout, or other labor trouble, embargo, sabotage, confiscation,
condemnation, riot, civil disturbance, activity of armed forces or act of God.

                  Section 4.15 Investment Company Act. Neither the Borrower nor
any Subsidiary is an "investment company" or a company "controlled" by an
investment company within the meaning of the Investment Company Act of 1940, as
amended.

                  Section 4.16 Public Utility Holding Company Act. Neither the
Borrower nor any Subsidiary is a "holding company" or a "subsidiary company" of
a holding company or an "affiliate" of a holding company or of a subsidiary
company of a holding company within the meaning of the Public Utility Holding
Company Act of 1935, as amended.

                  Section 4.17 Retirement Benefits. Except as required under
Section 4980B of the Code, Section 601 of ERISA or applicable state law, neither
the Borrower nor any Subsidiary is obligated to provide post-retirement medical
or insurance benefits with respect to employees or former employees.

                  Section 4.18 Full Disclosure. Subject to the following
sentence, neither the financial statements referred to in Section 4.5 nor any
other certificate, written statement, exhibit or report furnished by or on
behalf of the Borrower in connection with or pursuant to this Agreement contains
any untrue statement of a material fact or omits to state any material fact
necessary in order to make the statements contained therein not misleading.
Certificates or statements furnished by or on behalf of the Borrower to the Bank
consisting of projections or forecasts of future results or events have been
prepared in good faith and based on good faith estimates and assumptions of the
management of the Borrower, and the Borrower has no reason to believe that such
projections or forecasts are not reasonable.

                  Section 4.19 Subsidiaries. The Borrower has only one
subsidiary, ACIC, of which it owns 100% of the common stock, which stock is the
only class of capital stock issued by ACIC.

                  Section 4.20 Year 2000. The Borrower has reviewed and assessed
it business operations and computer systems and applications to address the
"year 2000 problem" (that is, that computer applications and equipment used by
the Borrower, directly or indirectly through third parties, may have been or may
be unable to properly perform date-sensitive functions before, during and after
January 1, 2000). The Borrower represents and warrants that the year 2000
problem has not resulted in and will not result in a material adverse change in
the Borrower's business condition (financial or otherwise), operations,
properties or prospects or ability to repay the Bank. The Borrower agrees that
this representation and warranty will be true and correct on and shall be deemed
made by the Borrower on each date the Borrower requests any Loan under this
Agreement or the Notes or delivers any information to the Bank. The Borrower
will promptly deliver to the Bank such information relating to this
representation and warranty as the Bank requests from time to time.

<PAGE>   30

                  knowledge of the Borrower, is threatened against the Borrower
                  or any Subsidiary or any of their respective properties which,
                  if determined adversely to such party, would constitute a

                  Section 5.2 Corporate Existence. The Borrower will maintain,
and cause each Subsidiary to maintain, its corporate existence in good standing
under the laws of its jurisdiction of incorporation and its qualification to
transact business in each jurisdiction where failure so to qualify would
permanently preclude the Borrower or such Subsidiary from enforcing its rights
with respect to any material asset or would expose the Borrower or such
Subsidiary to any material liability; provided, however, that nothing herein
shall prohibit the merger or liquidation of any Subsidiary allowed under Section
6.1.

                  Section 5.3 Insurance. The Borrower shall maintain, and shall
cause each Subsidiary to maintain, with financially sound and reputable

required by law to be filed by it and will pay, and cause each Subsidiary to
pay, before they become delinquent all taxes, assessments and governmental
charges and levies imposed upon it or its property and all claims or demands of
any kind (including but not limited to those of suppliers, mechanics, carriers,
warehouses, landlords and other like Persons) which, if unpaid, might result in
the creation of a Lien upon its property; provided that the foregoing items need
not be paid if they are being contested in good faith by appropriate
proceedings, and as long as the Borrower's or such Subsidiary's title to its
property is not materially adversely affected, its use of such property in the
ordinary course of its business is not materially interfered with and adequate
reserves with respect thereto have been set aside on the Borrower's or such
Subsidiary's books in accordance with GAAP.

                  Section 5.5 Inspection. Subject to Section 8.7, the Borrower

affairs, finances and accounts of the Borrower and the Subsidiaries with, and to
be advised as to the same by, its officers at such reasonable times and
intervals as the Bank may designate. So long as no Event of Default exists, the
expenses of the Bank for such visits, inspections and examinations shall be at
the expense of the Bank, but any such visits, inspections and examinations made
while any Event of Default is continuing shall be at the expense of the
Borrower.

will cause each Subsidiary to keep, adequate and proper records and books of
account in which full and correct entries will be made of its dealings, business
and affairs.

cause each Subsidiary to comply, in all material respects with all laws, rules,
regulations, orders, writs, judgments, injunctions, decrees or awards to which
it may be subject; provided, however, that failure so to comply shall not be a
breach of this covenant if such failure does not have, or is not reasonably
expected to have, a materially adverse effect on the properties, business,
prospects or condition (financial or otherwise) of the Borrower or such
Subsidiary and the Borrower or such Subsidiary is acting in good faith and with
reasonable dispatch to cure such noncompliance.

                  Section 5.9 Notice of Litigation. The Borrower will give
prompt written notice to the Bank of the commencement of any action, suit or
proceeding before any court or arbitrator or any governmental department, board,
agency or other instrumentality affecting the Borrower or any Subsidiary or any
property of the Borrower or a Subsidiary or to which the Borrower or a
Subsidiary is a party in which an adverse determination or result could have a
material adverse effect on the business, operations, property or condition
(financial or otherwise) of the Borrower and the Subsidiaries taken as a whole
or on the ability of the Borrower or any Subsidiary to perform its obligations
under this Agreement and the other Loan Documents, stating the nature and status
of such action, suit or proceeding.

                  Section 5.10 ERISA. The Borrower will maintain, and cause each

requirements of ERISA and of the Code and with all applicable rulings and
regulations issued under the provisions of ERISA and of the Code and will not
and not permit any of the ERISA Affiliates to (a) engage in any transaction in
connection with which the Borrower or any of the ERISA Affiliates would be
subject to either a civil penalty assessed pursuant to Section 502(i) of ERISA
or a tax imposed by Section 4975 of the Code, in either case in an amount
exceeding $100,000, (b) fail to make full payment when due of all amounts which,
under the provisions of any Plan, the Borrower or any ERISA Affiliate is
required to pay as

will observe and comply with, and cause each Subsidiary to observe and comply
with, all laws, rules, regulations and orders of any government or government
agency relating to health, safety, pollution, hazardous materials or other

liability or otherwise have a material adverse effect on the Borrower and the
Subsidiaries taken as a whole. The Borrower will give the Bank prompt written
notice of any violation as to any environmental matter by the Borrower or any
Subsidiary and of the commencement of any judicial or administrative proceeding
relating to health, safety or environmental matters (a) in which an adverse
determination or result could result in the revocation of or have a material
adverse effect on any operating permits, air emission permits, water discharge
permits, hazardous waste permits or other permits held by the Borrower or any
Subsidiary which are material to the operations of the Borrower or such
Subsidiary, or (b) which will or threatens to impose a material liability on the
Borrower or such Subsidiary to any Person or which will require a material
expenditure by the Borrower or such Subsidiary to cure any alleged problem or
violation.

                  Section 5.12 Further Assurances. The Borrower shall promptly
correct any defect or error that may be discovered in any Loan Document or in

or consolidate or enter into any analogous reorganization or transaction with
any Person; liquidate, wind up or dissolve itself (or suffer any liquidation or
dissolution); acquire all or substantially all of the stock or the assets of

however, any Subsidiary may be merged with or liquidated into the Borrower or
any wholly-owned Subsidiary (if the Borrower or such wholly-owned Subsidiary is
the surviving corporation).

                  Section 6.2 Disposition of Assets. The Borrower will not, and

                  Section 6.3 Plans. The Borrower will not permit, and will not
allow any Subsidiary to permit, any event to occur or condition to exist which

Borrower or any Subsidiary; and the Borrower will not permit, as of the most
recent valuation date for any Plan subject to Title IV of ERISA, the present
value (determined on the basis of reasonable assumptions employed by the
independent actuary for such Plan and previously furnished in writing to the
Bank) of such Plan's projected benefit obligations to exceed the fair market
value of such Plan's assets.

date hereof. For purposes of this Section 6.4, the provision of claims
management, disability management, the provision and sale of software related to

Subsidiary of the Borrower, as carried on at the date hereof.

thereof, or deposits and credits held for the account of the Borrower is or are

restriction on the Bank to all rights of banker's Lien, setoff and counterclaim
available pursuant to law.

or the holder of a Note to exercise and no delay in exercising any power or
right hereunder or under any other Loan Document shall operate as a waiver
thereof; nor shall any single or partial exercise of any power or right preclude
any other or further exercise thereof or the exercise of any other power or
right. The remedies herein and in the other Loan Documents provided are
cumulative and not exclusive of any remedies provided by law.

assignment to a Transferee, then upon notice to the Borrower such Transferee, to
the extent of such assignment (unless otherwise provided therein), shall become
a "Bank" hereunder and shall have all the rights and obligations of the Bank
hereunder to the extent of its Transferred Interest and the Bank shall be
released from its duties and obligations under this Agreement to the extent of
such assignment. Notwithstanding the sale by the Bank of any participation
hereunder, no participant shall be deemed to be or have the rights and
obligations of the Bank hereunder except that any participant shall have a right
of setoff under Section 7.3 as if it were the Bank and the amount of its
participation were owing directly to such participant by the Borrower.

other relationship between the Bank and the Borrower (collectively,

employees and agents of the Bank and its Affiliates, except that such persons
may disclose Confidential Borrower Information: (a) to their attorneys and
accountants, (b) in connection with the enforcement of the rights of the Bank
hereunder and under the Notes and the Security Documents or otherwise in
connection with applicable litigation, (c) in connection with assignments and

may otherwise be required or requested by any regulatory authority having

judicial process, the opinion of the Bank's counsel concerning the making of
such disclosure to be binding on the parties hereto. The Bank shall not incur
any liability to the Borrower by reason of any disclosure permitted by this
Section 8.7.

BORROWER COMMENCES ANY ACTION IN ANOTHER JURISDICTION OR VENUE UNDER ANY TORT OR
CONTRACT THEORY ARISING DIRECTLY OR INDIRECTLY FROM THE RELATIONSHIP CREATED BY

by the Borrower of the Notes, regardless of any investigation made by or on
behalf of the Bank, and shall continue in full force and effect as long as any

not been terminated; provided, however, that the obligations of the Borrower
under Section 8.2, 8.5 and 8.12 shall survive payment in full of the Obligations
and the termination of the Revolving Commitment.

                            MATTERS TO BE COVERED BY
                               OPINION OF COUNSEL
                                 TO THE BORROWER

         The opinion of counsel to the Borrower which is called for by Article
III of the Credit Agreement dated as of March __, 2000 (the "Credit Agreement")
shall be addressed to the Bank and dated the date of the Credit Agreement. It
shall be satisfactory in form and substance to the Bank and shall cover the
matters set forth below, subject to such assumptions, exceptions and
qualifications as may be acceptable to the Bank and counsel to the Bank.
Capitalized terms used herein have the respective meanings given such terms in
the Credit Agreement and the Loan Documents.

         (i) The Borrower is a corporation duly incorporated and validly
existing and in good standing under the laws of the State of Minnesota and has
all requisite corporate power and authority to carry on its business as now
conducted, to enter into the Loan Documents and to perform all of its
obligations under the Loan documents. The Borrower is duly qualified and in good
standing as a foreign corporation in all of the jurisdictions in which the
character of the properties owned or leased by it or the business conducted by
it makes such qualification necessary and the failure to so qualify would
permanently preclude the Borrower from enforcing its rights with respect to any
material asset or expose the Borrower to any material liability.

         (ii) The execution, delivery and performance by the Borrower of the
Loan Documents has been duly authorized by all necessary corporate action by the
Borrower.

         (iii) The Loan Documents constitute the legal, valid and binding
obligations of the Borrower, enforceable against the Borrower in accordance with
their respective terms.

         (iv) The execution and delivery of the Loan Documents and the
performance by the Borrower of the Loan Documents will not (i) violate any
provision of any law, statute, rule or regulation or, to the best knowledge of
such counsel, any order, writ, judgment, injunction, decree, determination or
award of any court, governmental agency or arbitrator presently in effect having
applicability to the Borrower, (ii) violate or contravene any provision of the
Articles of Incorporation or bylaws of the Borrower, or (iii) result in a breach
of or constitute a default under any indenture, loan or credit agreement or any
other agreement, lease or instrument to which the Borrower is a party or by
which it or any of its properties may be bound or result in the creation of any
Lien thereunder.

         (v) No order, consent, approval, license, authorization or validation
of, or filing, recording or registration with, or exemption by, any governmental
or public body or authority is required on the part of the Borrower to
authorize, or is required in connection with the execution, delivery and
performance of, or the legality, validity, binding effect or enforceability of,
the Loan Documents.

<PAGE>   50

         (vi) To the best knowledge of such counsel, there are no actions, suits
or proceedings pending or threatened against or affecting the Borrower or any of
its properties before any court or arbitrator, or any governmental department,
board, agency or other instrumentality which (i) challenge the legality,
validity or enforceability of the Loan Documents, or (ii) if determined
adversely to the Borrower, would have a material adverse effect on the business,
operations, property or condition (financial or otherwise) of the Borrower and
the Subsidiaries as a consolidated enterprise or on the ability of the Borrower
to perform its obligations under the Loan Documents.

         (vii) The Pledge Agreement creates the Lien it purports to create upon
the properties and interests specifically described therein. The descriptions of
properties and interests in the Pledge Agreement and any related financing
statements are adequate for the purpose of such instruments and for perfection
of the Liens of the Bank.
