         For purposes hereof, the "Maturity Date" shall be the earlier to occur

Company.

     2. Payments of principal or interest on this Note shall be made, in
accordance with the foregoing and subject to applicable laws and regulations, to
the Holder at the principal business office of the Holder or such other place,
which shall be acceptable to the Company, as the Holder hereof shall designate
in writing to the Company. Payments shall be made in immediately available funds

interest on this Note on a Scheduled Interest Payment Date or the Maturity Date
thereof, as specified herein, the Scheduled Interest Payment Date or Maturity

such conditions are met and such payment shall be made by the Company on the
Business Day following the Business Day on which the Company shall have the
approval of the Director to make such payment. Interest will continue to accrue
at the rate of interest stated on the face hereof through the actual date of

payment (i) on any such unpaid principal (but not on interest with respect to
which a Scheduled Interest Payment Date has been extended, during the period of
such extension) and (ii) to the extent permitted by law, on interest with
respect to which the approval of the Director has been obtained and which is not
punctually paid or duly provided for on the Scheduled Interest Payment Date.

day in which banking institutions are authorized or required by law to close in

unpaid, the Company shall use its reasonable good faith efforts to obtain the
approval of the Director for the payment by the Company of interest on and
principal of this Note on the Scheduled Interest Payment Dates or Maturity Date
thereof, and in the event any such approval has not been obtained for any such
payment at or prior to a Scheduled Interest Payment Date or the Maturity Date
thereof, as the case may be, to continue to use its reasonable good faith
efforts to obtain such approval promptly thereafter. The Company shall notify or
cause to be notified the Holder promptly following any Scheduled Interest
Payment Date for interest on or the Maturity Date for principal of this Note in
the event that the Director has not approved the making of any such payment on
such Scheduled Interest Payment Date or such Maturity Date and the Company shall
have failed to make any such payment on any such Scheduled Interest Payment Date
or such Maturity Date.

     5. (a) The Company agrees, the Holder of this Note by accepting this Note
agrees, that the Indebtedness evidenced by this Note is subordinated in right of
payment to the extent and in the manner provided in this Paragraph 5, to the
prior payment in full of all Indebtedness and Claims (each as hereinafter
defined).

     (b) Upon any distribution to creditors of the Company in any
rehabilitation, liquidation, conservation, or dissolution proceeding relating to
the Company or its property, the Holder of Indebtedness and the Holders of
Claims will first be entitled to receive payment in full of all amounts due or
to become due with respect thereto before the Holders will be entitled to
receive any payment in respect of the principal of or interest on this Note.

     (c) If a distribution is made to the Holder of this Note that, because of
this Paragraph 5, should not have been made to such Holder, such Holder who
received the distribution shall hold it in trust for Holders of Claims and
Indebtedness and pay it over to them as their interests may appear, provided,
however, that no such payment over shall be required following 120 days after
the Holder receives any such distribution.

     (d) This Paragraph 5 defines the relative rights of this Holder of this
Note, on the one hand, and Holders of any other claims, in accordance with SDCL
Chapter 58-29B, et seq. and any successor provisions, in each case as may be
amended from time to time (the "Liquidation Act"), on the other hand. Nothing in
this Note shall (i) impair, as between the Company and the Holder of this Note,
the obligation of the Company which is, subject to the Payment Restrictions,
absolute and unconditional to pay principal of and interest on this Note in
accordance with its terms; or (ii) affect the relative rights of the Holder of
this Note and creditors of the Company, other than Holders of Claims or
Indebtedness; or (iii) prevent the Holder of this Note from exercising any
available remedies upon a breach by the Company of its obligations hereunder,
subject to the rights of Holders Claims or Indebtedness to receive distributions
otherwise payable to the Holder of this Note.

                                       2

     (e) The Holder of this Note, by acceptance hereof, agrees to take such
action as may be necessary or appropriate to effectuate the subordination
provided in this Paragraph 5.

     As used herein, "Indebtedness" of the Company shall mean (i) all existing
or future indebtedness of the Company for borrowed money, goods, services, or
the like, (ii) all existing or future indebtedness for borrowed money, goods,
services, or the like of other persons, the payment of which is guaranteed by
the Company, (iii) all existing or future obligations of the Company under any
agreement obligating the Company to cause another person to maintain a minimum
level of net worth or otherwise to ensure the solvency of such person, and (iv)
all other claims or amounts owed, to the extent that the payment of principal
of, interest on and any other amount due with respect to this Note is required
by the Liquidation Act or otherwise by law to be subordinated to the prior
payment of any such claim or amount. Any indebtedness of any surplus notes or
similar obligations of the Company which by their express terms rank pari passu
with, or are subordinate to right of payment to, this Note shall not constitute
Indebtedness.

     As used herein, "Claims" shall mean all existing or future claims of
policyholders, beneficiaries and insureds under any and all existing or future
policies, endorsements, riders, and other contracts of insurance issued, assumed
or renewed by the Company , all existing or future claims of cedents,
retrocessionaires and/or reinsurers of the Company with respect to treaties,

pursuant thereto) to which the Company is a party, and all claims of the South
Dakota Property and Casualty Insurance Guaranty Association, or any similar
organization in another state, and all other claims of any general creditor of
the Company (but not including any claims arising from any express terms which
rank pari passu with, or are subordinate in right of payment to, this Note).

     6. The Holder of this Note may enforce this Note only in the manner set
forth below.

     (a) In the event that any state or federal agency shall obtain an order or
grant approval for the rehabilitation, liquidation, cancellation or dissolution
of the Company, this Note will upon the obtaining of such an order or the
granting of such approval immediately mature in full without any action on the
part of the Holder of this Note, with payment thereon being subject to the
Payment Restrictions, and any restrictions imposed as a consequence of, or
pursuant to, such proceedings. Notwithstanding any other provision of this Note,
in no event shall the Holder of this Note be entitled to declare this Note to
immediately mature or otherwise be immediately payable.

     (b) In the event that the Director approves in whole or in part a payment
of any interest on or principal of this Note and the Company fails to pay the
full amount of such approved payment on the date such amount is scheduled to be
paid, such approved amount will be immediately payable on such date without any
action on the part of the Holder of this Note, and the Holder of this Note may
pursue any available remedy to collect such approved payment of principal of or
interest, together with such further amount as shall be sufficient to cover the
reasonable costs and expenses of collection, including reasonable attorneys'
fees. In the event that the Company fails to perform any of its other
obligations hereunder, the Holder of this note may pursue any available remedy
to enforce the performance of any provision of this Note, provided, however,
that such remedy shall in no event include the right to declare this Note
immediately payable. A delay or omission by the Holder of this Note in
exercising any right or remedy accruing as a result of the Company's failure to
perform its obligations hereunder shall not impair such right or remedy or
constitute a waiver of or acquiescence in such nonperformance by the Company. To
the extent permitted by law, no remedy is exclusive of any other remedy and all
remedies are cumulative.

Holder of this Note to receive payment of the principal of and interest on this
Note, on or after the respective Scheduled Interest Payment Date or Maturity
Date, or to bring suit for the enforcement of any such payment on or after such
respective Dates, in each case subject to such payment on such Dates having
received the approval of the Director pursuant to the Payment Restrictions, is
absolute and unconditional and shall not be impaired or affected without the
consent of the Holder.

     7. No recourse shall be had for the payment of the principal of or interest
on this Note or for any claim based hereon or otherwise in respect hereof,
against any incorporator, stockholder, officer or director, as such, past,
present or future, of the Company or of any affiliate, predecessor or successor
corporation, either directly or through the Company or otherwise, whether by
virtue of any constitution, statute or rule of law, or by the enforcement of any
assessment or penalty, or otherwise, all such liability being by the acceptance
hereof expressly waived and released; provided, however, that nothing contained
herein shall be taken to prevent recourse to and enforcement of the liability,
if any of any shareholder, or any stockholder or subscriber to common capital
stock of the Company upon or in respect of shares of capital stock not fully
paid up.

     8. This Note shall be governed by, and construed in accordance with, the
law of the State of South Dakota. Without limiting the foregoing, the Director's
exercise of regulatory authority, including approval of payments under this
Note, shall be governed by, and construed in accordance with, the law of the
State of South Dakota.

     9. The invalidity of any provision of this Note shall in no way affect the
validity of any other provision. This Note is binding upon and shall inure to
the benefit of the parties hereto and their heirs, successors, personal
representatives, and permitted assigns. The Note may not be changed, waived, or
terminated except in a writing signed by the party against whom enforcement of

THIS AGREEMENT, made as of this 1st day of JULY 2002, by and among State Auto
Property and Casualty Insurance Company ("State Auto P&C"), Meridian Insurance
Group, Inc. ("MIGI"), Meridian Security Insurance Company ("Security"), Meridian
Citizens Mutual Insurance Company ("Citizens"), and Meridian Citizens Security
Insurance Company ("Meridian Citizens").

WHEREAS, the Boards of Directors of State Auto P&C, MIGI, Security, Citizens,
and Meridian Citizens, (Security, Citizens, Meridian Citizens are collectively
referred to hereafter as the "MIGI Insurers" (individually as a "MIGI Insurer")
and together with MIGI, the "MIGI Companies") have resolved to change the
employer of those persons providing services to the MIGI Companies from MIGI to
State Auto P&C effective January 1, 2002; and

WHEREAS, State Auto P&C desires to make available to the MIGI Companies and the
MIGI Companies desire to obtain from State Auto P&C the services of State Auto
P&C through its executive, managerial, administrative and other employees and
human resources; and

WHEREAS, the MIGI Insurers participate in the Reinsurance Pooling Agreement,
Amended and Restated as of July 1, 2001 (the "MIGI Pooling Agreement" or the
"MIGI Pool" or the "MIGI Pooling Arrangement") while State Auto P&C with other
affiliates participates in the Reinsurance Pooling Agreement, Amended and
Restated as of January 1, 2000, as subsequently amended, (the "State Auto
Pooling Agreement" or the "State Auto Pool" or the "State Auto Pooling
Arrangement"); and

WHEREAS, it is necessary to provide for the allocation and apportionment of
certain expenses of the MIGI Companies as described below and to specifically
address the matter of a service fee based on certain categories of expenses to
be reimbursed by the MIGI Companies to State Auto P&C.

NOW, THEREFORE, in consideration of the premises and the mutual promises
contained herein, AND INTENDING TO BE LEGALLY BOUND HEREBY, the parties hereto
agree as follows:

1. State Auto P&C, through its employees, shall operate, administer, and manage
the day-to-day business operations of and otherwise perform Management and
Operations Services (as defined below) for each of the MIGI Companies in
accordance with the underwriting, claims and any other reasonable guidelines of
such companies which may be in effect or established from time to time by the
respective board of directors of each such MIGI Company. The management and
administration of each such company's business operations by State Auto P&C
shall include, without limitation, appointment and termination of agencies,
underwriting of insurance risks, investigation and settlement of claims and
arrangement of reinsurance, as well as every other business operation that
supports or attends the performance of those services or other business
functions of each of the MIGI Companies. State Auto P&C shall use the same
degree of care in acting on behalf of such insurers as it uses in connection
with the conduct of its insurance business operations. For the purposes of this
agreement it is understood and agreed that Management and Operations Services
means all services, including without limitation, executive, managerial,
supervisory, administrative, technical, professional, and clerical services,
necessary or appropriate in the operation of the respective businesses of each
of the MIGI Companies. Any of State Auto P&C's employees may also serve as
directors or officers of any of the MIGI Companies, notwithstanding that such
persons may also be officers or directors of State Auto P&C. State Auto P&C
shall have the right to continue using for its

<PAGE>

business operations all of its employees provided to the other parties
hereunder. To the extent reasonably possible, the parties shall jointly utilize
State Auto P&C's employees in a cooperative manner and consistent with the best
business interests and needs of the MIGI Companies and State Auto P&C. State
Auto P&C shall direct its employees, in performing such services for the MIGI
Companies, to use their best efforts to promote the general interests and
economic welfare of the MIGI Companies in the same manner as such employees
provide services to their direct employer. Nothing contained in this Agreement
shall impair the authority and responsibility of the Board of Directors of any
of the MIGI Companies to exercise managerial control as provided in said
companies' Articles of Incorporation.

2. Because the State Auto Companies operate their insurance business utilizing
employees of one employer, subject to the provisions of the MIGI Pooling
Agreement, the non-direct expenses incurred by State Auto P&C for the benefit of
the MIGI Companies shall be apportioned to each of the MIGI Companies, in
accordance with the provisions of this Agreement and reimbursed to State Auto
P&C by each of the MIGI Companies in accordance with the provisions of this
Agreement.

3. As a service fee, in consideration of the services provided and the
efficiencies achieved through the combination of the companies' operations that
would not be available in the absence of such combination, each MIGI Company
shall pay to State Auto P&C for the employees provided hereunder an amount equal
to ten (10%) percent of all State Auto P&C's employee related costs, including
salaries, payroll taxes and employee relations and welfare expenses apportioned
to each MIGI Company. Said service fee shall be paid quarterly in accordance
with section 4 hereof.

4. All amounts due under this Agreement shall be due and payable by the
respective company within fifteen days after request for payment from the party
to be paid. The amounts due from each MIGI Company hereunder shall be recomputed
by State Auto P&C on a semi-annual or annual basis as appropriate to accurately
determine such amounts, using statutory accounting principles and appropriate
bases of allocation and apportionment supported by work papers. Any resulting
adjustments shall be settled between the parties or credited to future payment
periods as may be determined by State Auto P&C. State Auto P&C shall make its
books and records available to the MIGI Companies during regular business hours
for the MIGI Companies to verify the accuracy of the calculations by State Auto
P&C of the payments due from the MIGI Companies hereunder.

5. Any notices to be given hereunder shall be in writing and shall be deemed
effective when delivered in person or by facsimile or, if mailed, two days after
mailing first class prepaid, to the address of the principal office of the party
to which the notice is being given.

6. This Agreement may not be assigned by any party without the prior written
consent of the other party. The provisions of this Agreement shall bind and
inure to the benefit of the parties and their respective successors and
permitted assigns.

7. This Agreement sets forth the entire agreement between the parties with
respect to the subject matter hereof and supersedes all prior or contemporaneous
agreements with respect thereto. Any modifications or amendments to this
Agreement must be in writing and signed by the parties to be bound.

                                       2

8. This Agreement shall be governed by and construed in accordance with the laws
of the State of Indiana both as to execution and performance.

9. This Agreement shall remain in force until terminated as provided herein. Any
party to this Agreement may terminate this Agreement by giving written notice to
the other party, stating a date certain not less than 180 days hence on which
such termination will become effective.
