EXHIBIT 23
 
                                      Agency Agreement                Allied
                                                                       Group
                                                                     Insurance

This Agreement entered this 1st day of September 1991, by and between the
undersigned insurance company or companies (hereinafter collectively called "the
Company") and ALLIED Group Insurance Marketing Company of ________________ in
the County of Polk and State if Iowa (hereinafter called "Agent").

                                  WITNESSETH:

In consideration of the mutual covenants herein contained and other good and 
valuable consideration, the parties hereto agree as follows:

I.   Appointment and Authority. That, upon the terms and conditions herein set
     forth, Company hereby appoints Agent its agent for the purpose of and with
     authority to solicit applications for insurance and bonds, deliver and
     countersign policies and endorsements thereon, deliver bonds, collect
     premiums for transmission of applications for insurance and endorsements to
     Company for approval and processing or disapproval, such authority to bind
     Company being subject to such restrictions as may be outlined in Company
     manual or otherwise imposed by Company from time to time.

     Nothing contained herein shall be construed to create the relation of
     employer and employee between Company and Agent. Agent shall be free to
     exercise his own judgement as to persons from whom he will solicit
     insurance or bonds and the time and place of solicitation, but Company may
     from time to time prescribe underwriting rules and regulations respecting
     the conduct of the business covered hereby (not interfering with such
     freedom of action of Agent), which underwriting rules and regulations shall
     be observed by Agent.

II.  Commissions. Company agrees to pay Agent commissions on all premiums
     remitted upon business solicited by him at the percentages determined in
     accordance with the commission schedule of Company in effect at the
     beginning of the policy period or term as stated in the original policy or
     in any extension or renewal thereof, or inception date of a Surety Bond, or
     effective date of annual or three-year premium period of a Fidelity Bond.
     Provided, further, that in the event that Company is ordered (either
     administratively or judicially), by any entity having appropriate
     jurisdiction, to refund any premium collected hereunder, the Agent's
     commission(s) must be adjusted to reflect such refund. That is, Agent's
     commission(s) will be reduced to reflect the fact that Company has refunded
     premium to an insured (or former insured) and, therefore, Agent's
     commission(s) must be adjusted accordingly. "Once this amount of
     overpayment, if any, is determined; Company will, on a case-by-case basis
     negotiate a repayment plan with Agent."
     
III. Supplies. Supplies furnished by Company to Agent for Agent's use in the
     conduct of his business shall be property of Company and shall at all times
     be subject to the inspection and control of Company. Company shall not
     otherwise be liable for any of Agent's expenses other than those which it
     may expressly agree to assume as a result of negotiations between the
     parties.

IV.  Remittance of Premiums. Premiums shall be considered due from Agent on the
     first day of the month following the month in which the policy or bond,
     additional premium, or excess audit has been charged to Agent's statement.
     If Agent has not remitted all such monies to Company within forty-five days
     from the end of the month in which the business is charged, all unremitted
     items in the statement shall become delinquent. Any credit given by Agent
     to an insured shall be at Agent's own risk, and any of the provisions
     herein contained shall not be construed as an authorization for the
     extension of credit by Agent to an insured on behalf of Company. Company
     may, at its option, take over for collection any and all delinquent items
     in Agent's statement not collected or remitted for by Agent and in such
     event, Agent agrees to waive commission thereon.

     Company shall make the necessary audits on policies and bonds written by 
     Agent requiring such audits for the computation of premium. In the event an
     additional premium is produced by any audit, such additional premium shall 
     be charged to Agent's account, and Agent agrees to collect the additional 
     premium from the Insured and

                                       1

 
     remit same to company less his commission within forty-five days from the
     end of the month in which such additional premium is charged to Agent's
     account. In the event Agent is unable to collect such additional premium
     within the forty-five day period, and within ten days after the expiration
     of said forty-five day period notifies Company in writing to this effect
     and requests Company to take over for direct collection such additional
     premium. Company agrees to assume responsibility for the collection of such
     additional premium less commission, and Agent agrees to waive all claims
     for commission credits thereon, if Agent fails to notify Company of his
     inability to collect additional premiums as herein provided, Agent agrees
     that he will pay such additional premiums to Company in accordance with the
     provisions of this Agreement. In the event any audit produces a return
     premium due the Insured, Agent agrees to pay said return premium less his
     commission, as provided in this Agreement. In the case of bonds which
     cannot be terminated by written notice to the obligee, Agent may, by like
     notice, relieve himself of the responsibility to collect and remit renewal
     premiums.

V.   Monies Due Agent. Company agrees to pay all monies due by it to Agent as
     shown by any monthly statement within forty-five days from the end of the
     month for which such statement is rendered: provided, however, that Company
     may accumulate monthly amounts payable is less that ten dollars until they
     equal or exceed such amount before making payment hereunder.

VI.  Premiums Constitute Trust Fund. It is specifically understood and agreed
     upon that all premiums collected by Agent are at all timed the property of
     Company as hereinbefore stated and shall not be used for any other purpose
     whatsoever except that permission is granted (until revoked) for Agent to
     use such portion of trusteed premiums as may be necessary to pay return
     premiums. The keeping of an account with Agent on Company's books as
     creditor and debtor account is declared a record memorandum of business
     transacted, and neither such keeping of account, nor alteration in
     compensation rate, nor failure to enforce prompt remittance or compromise
     or settlement or declaration of balance of account, shall be held to waive
     assertion of trust relation as to premiums collected by Agent. It is
     further understood and agreed that the commission which Company agrees to
     pay Agent a lien or claim on said premiums, and in case Company allows
     Agent, for the purpose of facilitating the handling of its business, to
     deduct the commission from premiums collected, it shall in no sense be
     construed as a waiver of its business, to deduct the commission from
     premiums collected, it shall in no sense be construed as a waiver of the
     rights of Company to its ownership of the premiums or in any manner affect
     the trust character of said premiums.

VII. Cancellation of Policies. Company shall have at all times the right to
     reject applications, alter, suspend or cancel any policy or bond (if bond
     form contains cancellation provision) and direct the return of the unearned
     premium thereon. Agent agrees to pay such unearned return premium in full
     to the Insured, and Company will credit Agent's account with the amount of
     said return premium, less return commission at the percent of commission in
     effect at the beginning of the policy period or term as stated in the
     original policy or any extension or renewal thereof, or inception date of a
     Surety Bond or effective date of an annual or three-year premium period of
     a Fidelity Bond.

     Flat cancellation will not be allowed to Agent on six months or three
     months auto plan policies, Commercial ALLIED Excess Liability Policies, or
     filed truck policies unless the policies are returned for calcellation
     prior to the effective date.

     Flat cancellation will be allowed on all other policies or bonds not
     accepted, delivered or paid for provided such policies or bonds are
     returned for cancellation within thirty days of the beginning of the policy
     period or term. However, if Agent permits such policies or bonds to remain 
     outstanding beyond thirty days, he shall be charged with and agrees to pay
     the pro rata earned premium commencing at the beginning of the policy
     period or term as stated in the original policy or any extension or renewal
     thereof, or inception date of a Surety Bond or effective date of an annual
     or three-year premium period of a Fidelity Bond.

VIII.Subagents. Agent may appoint subagents, subject to approval of Company, and
     such subagents shall for the purpose of this Agreement be deemed employees
     of Agent. Agent shall be responsible for the premiums, commissions, charges
     or expenses of subagents or other persons from whom he may procure
     business.

X.   Ownership of Expirations. Upon termination of this Agreement by either
     party hereto, if Agent's account is not then delinquent and if Agent shall
     thereafter remit to Company within forty-five days from the end of the
     month in which business is charged to Agent, all monies due to Company, the
     records, use and control of expirations shall be deemed the property of
     Agent; otherwise the records, use and control of expirations shall be
     vested in Company.

                                       2

 
XI.  Termination. Either Company or Agent may terminate this Agreement at any
     time by notice in writing to the other effective immediately; provided,
     however, that if Agent's account with Company is not delinquent or Agent
     has not otherwise violated the terms of this Agreement and Agent has not
     requested termination, Company shall give Agent not less than ninety days
     written notice of any such termination. Upon termination, Agent shall
     immediately surrender and return to Company his license (subject to
     applicable Insurance Department requirements) and all policies, supplies or
     other property of the Company in his possession if requested to do so by
     Company. Upon termination of the Agreement by either party hereto, all
     monies and premiums which have been collected by Agent that are delinquent
     shall become due and payable to Company upon the effective date of the
     termination of the Agreement. In the event this Agreement is terminated by
     Company for violation of its terms by Agent, Agent relinquishes all right
     or claim to commission on subsequent, excess or additional premiums
     developed, and Company shall have the right to collect all outstanding
     premiums if it so elects, and Agent agrees to waive or relinquish his right
     or claim for commission on same. In the event it becomes necessary for
     Company to institute legal proceedings for the recovery of any monies due
     Company from Agent, Agent agrees to pay all reasonable attorney fees, legal
     costs of such proceedings, and interest at the legal rate upon such monies
     from the date upon which they become due and payable to Company.

     Effective immediately upon such termination, except as otherwise provided
     hereinafter, the agency relationship existing between Company and Agent by
     virtue of this Agreement shall cease, and all previous contracts,
     agreements, understanding or arrangements of every kind, whether oral or
     written, creating or providing for such agency for Company or authorizing
     Agent to write or issue policies of insurance or bonds for Company or to
     solicit or take applications therefor, shall terminate. Agent agrees to pay
     all sums due from Agent to Company on business written prior to such
     termination date and all other monies due upon receipt of any monthly
     statement thereafter. Agent agrees to report to Company all policies or
     bonds issued or bound by Agent prior thereto. Agent's liability to account
     to Company for premiums collected and to pay over to it any monies due
     hereunder shall survive any termination of this Agreement.

XII. Limited Agency Following Termination. If Agent's account with Company is
     not delinquent on the effective date of termination of the Agreement and
     Agent is not otherwise in default under any terms of such Agreement,
     Company agrees that following any such termination existing business
     written by Agent will be allowed to run until expiration and Agent shall
     have limited authority with respect thereto as follows:

     1.   Agent may elect to continue outstanding policies and bonds previously
          written through Agent in force until expiration, subject to
          cancellation privileges by Company of the policyholder prior to
          expiration, and in such event Agent agrees to service such policies
          and bonds, collect premiums due thereon, if any, on the due date
          thereof and remit the collections promptly to Company. Any unearned
          commission on return premiums will be charged to Agent's account and
          Agent agrees to repay the same to Company forthwith on receipt of
          billing thereof. In case an audit of outstanding policies or bonds
          requires an additional premium to be assessed against the policyholder
          or obligor, Agent agrees to collect the same on the due date and make
          prompt remittance thereof to Company. In the event Agent is not able
          to collect such premiums within forty-five days from the end of the
          month in which such premium is charged to his account, Agent may
          relieve himself of the responsibility to collect and remit such
          premium by notice to Company within the time and in the manner
          provided in such cases under "Remittance of Premiums" in the
          Agreement, and thereupon Company agrees to assume collection thereof,
          as therein provided.

     2.   Company agrees to pay Agent commissions on policies or bonds in force
          until expiration or cancellation at the same rates as it then pays
          commissions on like business to existing Agents in Agent's state.

     3.   Agent shall have the right to request appropriate endorsements on
          policies or bonds in force, provided that no such endorsements shall
          increase or extend Company's liability or extend the term of any
          policy or bond unless prior approval of Company shall have been
          obtained.

     4.   Unless sooner cancelled, these limited agency provisions shall
          continue all policies and bonds written by Agent for Company shall
          have expired.
 
     5.   The provisions of the Agreement entitled "Premiums Constitute Trust
          Fund" shall apply to premiums collected by Agent during the period of
          limited agency hereunder. If Agent has not remitted all monies due to
          Company within forth-five days from the end of the month in which
          business is charged. Agent agrees that the records, use and control of
          the expirations shall be vested in Company; otherwise, the records,
          use and control of the expirations shall be deemed the property of
          Agent.

XIII. Indemnification Agreement. The Company agrees to defend and indemnify 
      Agent against liability, including the cost of defense and settlements,
      imposed on him by law (including the Fair Credit Reporting Act -- Public
      Law 91-508) for damages caused by acts or omissions of the Company,
      provided Agent has not caused or contributed to such liability by his own
      acts or omissions. Agent agrees, as a condition to such indemnification,
      to notify the Company promptly of any such against him and to allow the
      Company to make such investigation, settlement, or defense thereof as the
      Company deems prudent.
