<PAGE>

            (b) Short-Form Registration. The Corporation shall prepare and file
with the Commission no later than the Target Filing Date, a "shelf registration
statement" on the appropriate form for an offering to be made on a continuous
basis pursuant to Rule 415 under the Securities Act, covering all of the
Registrable Shares then owned by the Holders (the "Shelf Registration
Statement," and collectively with the Long-Form Demand Registration, the "Demand
Registrations"). The Corporation will use its best efforts to have the Shelf
Registration Statement declared effective on or before the Target Effective Date
and to keep such Shelf Registration Statement continuously effective for the
Effective Period (or such shorter period which will terminate when all
Registrable Securities covered by such Shelf Registration Statement have been
sold or withdrawn, but not prior to the expiration of the applicable period
referred to in Section 4(3) of the Securities Act and Rule 174 thereunder, if
applicable). The Corporation further agrees, if necessary, to supplement or
amend the Shelf Registration Statement, as required by the rules, regulations or
instructions applicable to the registration form used by the Corporation for
such Shelf Registration Statement or by the Securities Act or as reasonably
requested (which request shall result in the filing of a supplement or
amendment) by any Holder of Registrable Securities to which such Shelf
Registration Statement relates, and the Corporation agrees to furnish to the
Holders, Holder's counsel and any managing underwriter copies of any such
supplement or amendment prior to its being used and/or filed with the
Commission.

                  (i) The Corporation may require each Holder of Registrable
            Securities to which such Shelf Registration Statement relates to
            furnish to the Corporation, upon reasonable notice, such information
            concerning the Holder and the distribution of the Registrable
            Securities as the Corporation may from time to time reasonably
            request, upon reasonable notice.

                  (ii) The Corporation shall not be deemed to have satisfied its
            obligations under Section 2(b) until the Shelf Registration
            Statement has been declared effective by the Commission and the
            Corporation has complied in all material respects with its
            obligations under this Agreement with respect thereto (including
            keeping the Shelf Registration Statement effective for the Effective
            Period), provided, however, that if after it has been declared
            effective, the offering of Registrable Shares pursuant to a Shelf
            Registration Statement is interfered with by any stop order,
            injunction or other order or requirement of the Commission or any
            other governmental agency or court, such Shelf Registration
            Statement will be deemed not to have been effective during the
            period of such interference until the offering of Registrable Shares
            pursuant to such Shelf Registration Statement may legally resume and
            the period of time during which sales under the Shelf Registration
            Statement were suspended shall be added to the Effective Period. If
            a registration requested pursuant to this Section 2(b) is deemed not
            to have been effected, then the Corporation shall continue to be
            obligated to effect a registration pursuant to this Section 2(b).

             (c) If the Holders so elect, the offering of Registrable Shares
pursuant to a Demand Registration shall be in the form of an underwritten
offering If they so elect, the Holders participating in such Demand Registration
shall select one or more nationally recognized firms of investment bankers
reasonably satisfactory to the Corporation to act as the book-running

                                       3
<PAGE>

managing underwriter or underwriters in connection with such offering and shall
select any additional investment bankers and managers to be used in connection
with the offering.

      (d) Priority on Demand Registrations. If a Demand Registration is an
underwritten public offering and the managing underwriters advise the
Corporation in writing that, in their opinion, the inclusion of the number of
Registrable Shares and other securities requested to be included in such
offering creates a substantial risk that the price per share of Common Stock
will be reduced, the Corporation will include in such Registration, prior to the
inclusion of any securities which are not Registrable Shares, the number of
Registrable Shares requested to be included which in the opinion of such
underwriters can be sold in such offering without creating such a risk,
allocated among the participating Holders as designated by AFG.

      (e) Restrictions on Registrations. The Corporation may postpone for a
reasonable period not to exceed ninety (90) days the filing or the effectiveness
of a registration statement for a Demand Registration if the Corporation shall
furnish to AFG a certificate signed by the Corporation's Chief Executive Officer
stating that the Board has determined reasonably and in good faith that such
filing would require a disclosure of a material fact concerning the Corporation
(which the Corporation is not otherwise required to disclose) that would have a
material adverse effect on the Corporation or adversely affect any plan by the
Corporation or any of its Subsidiaries to engage in any acquisition of assets
(other than in the ordinary course of business) or capital stock or other
securities of any other entity, or any financing, acquisition, reorganization,
merger, consolidation, tender offer or other significant transaction; provided,
that the right to postpone may not be exercised for more than 120 days in any
12-month period. The Corporation will not include in any Demand Registration,
that is an underwritten offering, any securities which are not Registrable
Shares without the written consent of the Holder or Holders of a majority of the
Registrable Shares to be included in such registration.

    3. Piggyback Registrations.

      (a) Right to Piggyback. Whenever securities of the Corporation are to be
registered under the Securities Act (other than pursuant to a Demand
Registration and other than pursuant to a registration statement on Form S-4 or
Form S-8 or successor forms) and the registration form to be used may be used
for the registration of Registrable Shares (a "Piggyback Registration"), the
Corporation will give prompt written notice (and in any event within three (3)
business days after its receipt of notice of any exercise of demand registration
rights by holders of the Corporation's securities other than the Registrable
Shares and at least twenty (20) days prior to the filing of any registration
statement) to AFG of its intention to effect such a registration and will
include in such registration all Registrable Shares with respect to which the
Corporation has received written requests for inclusion therein within 10 days
after the Corporation's notice has been given. If a Holder desires to include
such Holder's Registrable Shares in a Piggyback Registration that is an
underwritten offering, such Holder shall, as a condition to including such
Holder's Registrable Shares, enter into an underwriting agreement containing
customary terms and conditions, including customary representations and
indemnities.

      (b) Priority on Primary Registrations. If a Piggyback Registration is an
underwritten primary registration on behalf of the Corporation, and the managing
underwriters

                                       4
<PAGE>

advise the Corporation that in their opinion the number of securities requested
to be included in such offering in the registration creates a substantial risk
that the price per share of Common Stock will be reduced in such offering, the
Corporation will include in such registration (i) first, the securities the
Corporation proposes to sell, (ii) second, the Registrable Shares requested to
be included in such registration, allocated among the participating Holders as
designated by AFG, and (iii) third, other securities requested to be included in
such registration.

             (c) Priority on Secondary Registrations. If a Piggyback
Registration is an underwritten secondary registration on behalf of holders of
the Corporation's securities (an "Initiating Securityholder"), and the managing
underwriters advise the Corporation that in their opinion the inclusion of the
number of securities requested to be included in such offering creates a
substantial risk that the price per share of Common Stock will be reduced in
such offering, the Corporation will include in such registration (i) first, the
Registrable Shares requested to be included in such registration, allocated
among the participating Holders as designated by AFG, and (ii) second, the
securities to be offered by the Initiating Securityholder and the Corporation in
such amounts as agreed upon between the Initiating Securityholder and the
Corporation.

             (d) Other Registrations. If the Corporation has previously filed a
registration statement which includes Registrable Shares pursuant to Section 2
or pursuant to this Section 3, and if such previous registration has not been
withdrawn or abandoned, the Corporation will not file or cause to be effected
any other registration of any of its equity securities or securities convertible
or exchangeable into or exercisable for its equity securities under the
Securities Act (except on Form S-4 or Form S-8 or successor forms), whether on
its own behalf or at the request of any holder or holders of such securities,
until a period of ninety (90) days has elapsed from the effective date of such
previous registration, without the prior consent of AFG.

        4. Holdback Agreements. The Corporation agrees (i) not to effect
any public sale or distribution of its equity securities, or any securities
convertible into or exchangeable or exercisable for such securities, during the
seven (7) days prior to and during the ninety (90) day period beginning on the
effective date of any underwritten Demand Registration or any underwritten
Piggyback Registration (except as part of such underwritten registration or
pursuant to a registration on Form S-4 or Form S-8 or successor forms), unless
the underwriters managing the registered public offering otherwise agree and
(ii) if requested by the underwriters managing the registered public offering,
to use its best efforts to cause each other holder of its equity securities, or
any securities convertible into or exchangeable or exercisable for such
securities, purchased from the Corporation at any time (other than in a
registered public offering) to agree not to effect any public sale of any such
securities during such period (except as part of such underwritten registration,
if otherwise permitted), unless the underwriters managing the registered public
offering otherwise agree.

        5. Registration Procedures.

             (a) Whenever AFG has requested that any Registrable Shares be
registered pursuant to the terms of this Agreement, the Corporation will use its
best efforts to effect the registration and the sale of such Registrable Shares
in accordance with the intended method of disposition thereof, and pursuant
thereto the Corporation will as expeditiously as possible:

                                       5
<PAGE>

            (i) prepare and file with the Commission a registration statement on
      the appropriate form with respect to such Registrable Shares and use its
      best efforts to cause such registration statement to become effective as
      soon as practicable after such filing;

            (ii) prepare and file with the Commission such amendments and
      supplements to such registration statement and the prospectus used in
      connection therewith as may be necessary to keep such registration
      statement effective and to comply with the provisions of the Securities
      Act with respect to the disposition of all securities covered by such
      registration statement until such time as the Registrable Shares
      registered thereunder have been disposed of in accordance with the
      intended methods of disposition by the sellers thereof set forth in such
      registration statement, but in no event for a period in excess of nine (9)
      months provided that, at least five (5) business days prior to filing a
      Registration Statement or Prospectus or any amendments or supplements
      thereto, excluding documents incorporated by reference after the initial
      filing of the Registration Statement, the Corporation shall furnish to the
      Holders of the Registrable Shares covered by such Registration Statement
      (the "Selling Holders"), Holders' counsel and the underwriters, if any,
      draft copies of all such documents proposed to be filed, which documents
      will be subject to the review of such Holders' counsel and the
      underwriters, if any, and the Corporation will not, unless required by
      law, file any Registration Statement or amendment thereto or any
      Prospectus or any supplement thereto to which Holders of at least a
      majority of the Registrable Shares (the "Objecting Party") shall
      reasonably object, pursuant to notice given to the Corporation prior to
      the filing of such amendment or supplement (the "Objection Notice") and no
      later than five (5) business days after receipt of the documents to which
      the Objection Notice relates. The Objection Notice shall set forth the
      objections and the specific areas in the draft documents where such
      objections arise. The Corporation shall have five (5) business days after
      receipt of the Objection Notice to correct such deficiencies to the
      satisfaction of the Objecting Party, and will notify each Selling Holder
      of any stop order issued or threatened by the Commission in connection
      therewith and shall use its best efforts to prevent the entry of such stop
      order or to remove it at the earliest possible moment if entered;

            (iii) furnish to each seller of such Registrable Shares and the
      underwriters of the securities being registered such number of copies of
      such registration statement, each amendment and supplement thereto, the
      prospectus included in such registration statement (including each
      preliminary prospectus) and such other documents as such seller or
      underwriters may reasonably request in order to facilitate the disposition
      of the Registrable Shares owned by such seller or the sale of such
      securities by such underwriters;

            (iv) use its best efforts to register or qualify such Registrable
      Shares under such other securities laws of such jurisdictions as any
      seller reasonably requests and do any and all other acts and things which
      may be necessary or desirable to enable such seller to consummate the
      public sale or other disposition in such jurisdictions of the Registrable
      Shares owned by such seller (provided, however, that the Corporation will
      not be required to qualify generally to do business in any jurisdiction
      where it would not

                                       6
<PAGE>

      otherwise be required to qualify but for this subparagraph or consent to
      general service of process in any such jurisdiction);

            (v) cause all such Registrable Shares to be listed on each
      securities exchange on which similar securities issued by the Corporation
      are then listed;

            (vi) enter into customary agreements (including underwriting
      agreements) and take all such other actions as AFG or the underwriters, if
      any, reasonably request in order to expedite or facilitate the disposition
      of such Registrable Shares;

            (vii) make available for inspection by AFG, any underwriter
      participating in any disposition pursuant to such registration statement,
      and any attorney, accountant or other agent designated by any such seller
      or underwriter, all financial and other records, pertinent corporate
      documents and properties of the Corporation, and cause the Corporation's
      officers, directors, employees and independent accountants to supply all
      information reasonably requested by any such seller, underwriter,
      attorney, accountant or agent in connection with such registration
      statement;

            (viii) notify each seller of such Registrable Shares, promptly after
      it shall receive notice thereof, of the time when such registration
      statement has become effective or a supplement to any prospectus forming a
      part of such registration statement has been filed;

            (ix) notify each seller of such Registrable Shares of any request by
      the Commission for the amending or supplementing of such registration
      statement or prospectus or for additional information;

            (x) prepare and file with the Commission, promptly upon the request
      of AFG, any amendments or supplements to such registration statement or
      prospectus which, in the reasonable opinion of counsel selected by AFG, is
      required under the Securities Act or the rules and regulations thereunder
      in connection with the distribution of Registrable Shares by AFG;

            (xi) prepare and promptly file with the Commission and promptly
      notify each seller of such Registrable Shares of the filing of such
      amendment or supplement to such registration statement or prospectus as
      may be necessary to correct any statements or omissions if, at the time
      when a prospectus relating to such securities is required to be delivered
      under the Securities Act, any event shall have occurred as the result of
      which any such prospectus would include an untrue statement of a material
      fact or omit to state any material fact necessary to make the statements
      therein, in the light of the circumstances in which they were made, not
      misleading; and

            (xii) at the request of any seller of such Registrable Shares in
      connection with an underwritten offering, furnish on the date or dates
      provided for in the underwriting agreement a customary opinion of counsel,
      addressed to the underwriters and AFG, covering such matters as such
      underwriters and sellers may reasonably request.

                                       7
<PAGE>

             (b) The Corporation may require AFG to furnish to the Corporation
such information regarding the distribution of such securities and such other
information relating to AFG and the AFG Entities, if applicable, participating
in such distribution, and the ownership by AFG and the AFG Entities, if
applicable, of Registrable Shares as the Corporation may from time to time
reasonably request in writing. AFG agrees to furnish such information to the
Corporation and to cooperate with the Corporation as reasonably necessary to
enable the Corporation to comply with the provisions of this Agreement.

        6. Registration Expenses. All expenses incident to the Corporation's
performance of or compliance with this Agreement, including, but not limited to,
all registration and filing fees, fees and expenses of compliance with federal,
state and foreign securities laws, printing expenses, messenger and delivery
expenses, and fees and disbursements of counsel for the Corporation and its
independent certified public accountants, underwriters (excluding discounts and
commissions attributable to the Registrable Shares included in such
registration) and other Persons retained by the Corporation (all such expenses
being herein called "Registration Expenses"), will be borne by the Corporation.
In addition, the Corporation will pay its internal expenses (including, but not
limited to, all salaries and expenses of its officers and employees performing
legal or accounting duties), the expense of any annual audit or quarterly
review, the expense of any liability insurance obtained by the Corporation and
the expenses and fees for listing the securities to be registered on each
securities exchange. The Holders shall pay the fees and disbursements of their
counsel in connection with any registration under this Agreement.

        7. Indemnification.

             (a) The Corporation agrees to indemnify, to the fullest extent
permitted by law, each seller of Registrable Shares, its officers and directors
and each Person who controls such seller (within the meaning of the Securities
Act or the Exchange Act) from and against all losses, claims, damages,
liabilities and expenses (including, but not limited to, reasonable attorneys'
fees except as limited by Section 7(c)) arising out of or based upon any untrue
or alleged untrue statement of a material fact contained in any registration
statement, prospectus or preliminary prospectus or any amendment thereof or
supplement thereto or any omission or alleged omission of a material fact
required to be stated therein or necessary to make the statements therein not
misleading or any violation by the Corporation of any Federal or state
securities laws, except insofar as the same are caused by or contained in any
information furnished in writing to the Corporation by such seller expressly for
use therein or by such seller's failure to deliver a copy of the prospectus or
any amendments or supplements thereto after the Corporation has furnished such
seller with a sufficient number of copies of the same. In connection with an
underwritten offering, the Corporation will indemnify such underwriters, their
officers and directors and each Person who controls such underwriters (within
the meaning of the Securities Act or the Exchange Act) to the same extent as
provided above with respect to the indemnification of the sellers of Registrable
Shares. The reimbursements required by this Section 7(a) will be made by
periodic payments during the course of the investigation or defense, as and when
bills are received or expenses incurred.

             (b) In connection with any registration statement in which a seller
of Registrable Shares is participating, each seller will furnish to the
Corporation in writing such

                                       8
<PAGE>

information and affidavits as the Corporation reasonably requests for use in
connection with any such registration statement or prospectus and, to the
fullest extent permitted by law, will indemnify the Corporation, its directors
and officers and each Person who controls the Corporation (within the meaning of
the Securities Act or the Exchange Act) from and against any losses, claims,
damages, liabilities and expenses (including, but not limited to, reasonable
attorneys' fees except as limited by Section 7(c)) resulting from any untrue
statement of a material fact contained in the registration statement, prospectus
or preliminary prospectus or any amendment thereof or supplement thereto or any
omission of a material fact required to be stated therein or necessary to make
the statements therein not misleading, but only to the extent that such untrue
statement or omission is contained in any information or affidavit so furnished
in writing by such seller; provided that the obligation to indemnify will be
several, not joint and several, among such sellers of Registrable Shares, and
the liability of each such seller of Registrable Shares will be in proportion to
the number of Registrable Shares sold by each such seller divided by the total
number of Registrable Shares included in such registration statement, and
provided further that such liability will be limited to, in any event, the net
amount received by such seller from the sale of Registrable Shares pursuant to
such registration statement.

             (c) Any Person entitled to indemnification hereunder will (i) give
prompt written notice to the indemnifying party of any claim with respect to
which it seeks indemnification and (ii) unless in such indemnified party's
reasonable judgment a conflict of interest between such indemnified and
indemnifying parties may exist with respect to such claim, permit such
indemnifying party to assume the defense of such claim with counsel reasonably
satisfactory to the indemnified party. If such defense is assumed, the
indemnifying party will not be subject to any liability for any settlement made
by the indemnified party without the indemnifying party's consent (but such
consent will not be unreasonably withheld). An indemnifying party who is not
entitled to, or elects not to, assume the defense of a claim will not be
obligated to pay the fees and expenses of more than one counsel for all parties
indemnified by such indemnifying party with respect to such claim, unless in the
reasonable judgment of any indemnified party a conflict of interest exists
between such indemnified party and any other of such indemnified parties with
respect to such claim.

             (d) If the indemnification provided for in this Section is held by
a court of competent jurisdiction to be unavailable to an indemnified party with
respect to any losses, claims, damages or liabilities referred to herein, the
indemnifying party, in lieu of indemnifying such indemnified party thereunder,
shall to the fullest extent permitted by applicable law contribute to the amount
paid or payable by such indemnified party as a result of such loss, claim,
damage or liability in such proportion as is appropriate to reflect the relative
fault of the indemnifying party on the one hand and of the indemnified party on
the other in connection with the matters that resulted in such loss, claim,
damage or liability, as well as any other relevant equitable considerations. The
relative fault of the indemnifying party and of the indemnified party shall be
determined by a court of law by reference to, among other things, whether the
untrue or alleged untrue statement of a material fact or the omission to state a
material fact related to information supplied by the indemnifying party or by
the indemnified party and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement of omission;
provided, that in no event shall the amounts payable in indemnity by a Holder
under Section 7 exceed the net proceeds received by such Holder in the
registered

                                       9

offering out of which such indemnification arises. No party guilty of fraudulent
misrepresentation under Section 11(f) of the Securities Act shall be entitled to
contribution under this Section 7(d).

             (e) Notwithstanding the foregoing, to the extent that the
provisions on indemnification and contribution contained in the underwriting
agreement entered into in connection with the underwritten pubic offering are in
conflict with the foregoing provisions, the provisions in the underwriting
agreement shall control.

             (f) The indemnification provided for under this Agreement will
remain in full force and effect regardless of any investigation made by or on
behalf of the indemnified party or any officer, director or controlling Person
of such indemnified party and will survive the transfer of securities.

        8. Compliance with Rule 144. At any time and from time to time after the
Corporation has a class of securities registered under Section 12 of the
Exchange Act, the Corporation will (i) make available to the public and such
holders such information as will enable the Holders to make sales pursuant to
Rule 144 promulgated under the Securities Act, and (ii) file with the Commission
in a timely manner all reports and other documents required of the Corporation
under the Exchange Act.

        9. Underwritten Registrations. AFG agrees, on its behalf and on behalf
of the AFG Entities, that, in connection with any underwritten offering, AFG
will (a) sell its Registrable Shares on the basis provided in any underwriting
arrangements approved by AFG and (b) complete and execute all questionnaires,
powers of attorney, indemnities, underwriting agreements and other documents
required under the terms of such underwriting arrangements. AFG will have the
right to select the managing underwriters to administer any offering of the
Corporation's securities in which the Corporation does not participate, subject
to the prior approval of the Corporation, which approval shall not be
unreasonably withheld, and the Corporation will have the right to select the
managing underwriters in any offering in which it does participate.

        10. Adjustments Affecting Registrable Shares. The Corporation will not
knowingly take any action, or knowingly permit any change to occur, with respect
to its securities which would materially adversely affect the ability of AFG to
include Registrable Shares in a registration undertaken pursuant to this
Agreement or which would materially adversely affect the marketability of such
Registrable Shares in any such registration.

        11. Remedies. Any Person having rights under any provision of this
Agreement will be entitled to enforce such rights specifically, to recover
damages caused by reason of any breach of any provision of this Agreement and to
exercise all other rights granted by law.

        12. Amendments and Waivers. Except as otherwise expressly provided
herein, the provisions of this Agreement may be amended or waived at any time
only by the written agreement of the Corporation and AFG. Any waiver, permit,
consent or approval of any kind or

                                       10

character on the part of any such holders of any provision or condition of this
Agreement must be made in writing and shall be effective only to the extent
specifically set forth in writing.

         13. Successors and Assigns. The rights to cause the Corporation to
register Registrable Securities granted pursuant to this Agreement may be
transferred or assigned by any Holder to a transferee or assignee, provided,
however, that the transferee or assignee of such rights, other than an AFG
Entity, assumes the obligations of such transferor or assignor, as the case may
be, under this Agreement and that such transferee or assignee executes and
delivers a copy of this Agreement to the Company.

         14. Entire Agreement. This Agreement constitutes the entire agreement
of the parties concerning the matters referred to herein, and supersedes all
prior agreements and understandings.

         15. Severability. Whenever possible, each provision of this Agreement
will be interpreted in such manner as to be effective and valid under applicable
law, but if any provision of this Agreement is held to be prohibited by or
invalid under applicable law, such provision will be ineffective only to the
extent of such prohibition or invalidity, without invalidating the remainder of
this Agreement.

         16. Descriptive Headings. The descriptive headings of this Agreement

                          INVESTMENT SERVICES AGREEMENT

         THIS INVESTMENT SERVICES AGREEMENT ("Agreement"), dated and effective
as of February 18, 2003, between INFINITY PROPERTY AND CASUALTY CORPORATION, an
Ohio corporation ("Company"), and AMERICAN MONEY MANAGEMENT CORPORATION, an Ohio
corporation ("American").

         WHEREAS, Company and its subsidiaries seek to obtain advice with
respect to the investment of their assets; and

         WHEREAS, American, an indirect wholly-owned subsidiary of American
Financial Group, Inc., an Ohio corporation ("AFG"), is willing and able to
supply such investment advice pursuant to the terms and conditions set forth
below;

         NOW, THEREFORE, for the consideration herein stated, the parties agree
as follows:

1.       INVESTMENT SERVICES.

         1.1. American shall furnish investment services to Company and its
         subsidiaries, which services shall include the following:

                  1.1.1.   to counsel and advise Company and its subsidiaries in
                           connection with the formulation of investment
                           programs and strategies designed to accomplish the
                           investment objectives of the Company and its
                           subsidiaries; and

                  1.1.2.   to manage the investment of the portfolio of
                           investment assets of the Company and its subsidiaries
                           in accordance with the investment policies,
                           objectives, directions and guidelines established by
                           their Boards of Directors or the Investment
                           Committee, as set forth in Section 1.3 below, and, in
                           connection therewith, to have full discretion and
                           authority, without prior consultation or prior
                           approval, to buy, sell and otherwise trade in bonds
                           and other fixed income securities and take such other
                           actions which American shall deem requisite,
                           appropriate or advisable.

         1.2. Custody and control of the securities and all other assets
         comprising the investment portfolio of the Company and its subsidiaries
         shall at all times be subject to the direction and control of the
         Company and its subsidiaries, acting through their Boards of Directors
         or an appropriate committee thereof. All purchases and sales of
         securities shall be in the name of the Company and its subsidiaries and
         all certificates or other instruments representing their investments
         shall be held in account at qualified depository institutions or in
         book form where appropriate. Such securities will be held in accounts
         segregated from those of American or its affiliates.

         1.3. American agrees that the investment services it furnishes will be
         in accordance with general investment policies, objectives, directions
         and guidelines established from time to time by the Board of Directors
         of the Company and its subsidiaries or an appropriate committee
         thereof. The investment guidelines of the Company and its subsidiaries
         will be made available to American. These provisions will change from
         time to time and Company and its subsidiaries, as soon as possible,
         will forward such changes to American which shall then comply with any
         revisions.

         1.4. Notwithstanding Section 1.1 above, American shall not invest any
         of such investment funds in securities of AFG or any of its
         subsidiaries or any affiliate of them, nor shall it invest such funds
         in any investment opportunity which was previously made available to
         and declined by AFG or any of its affiliates, without first obtaining
         the written approval of an officer that the Company shall designate in
         writing who shall initially be Roger Smith.

         1.5 For providing services hereunder, American shall comply with all
         applicable laws, rules and regulations, and shall maintain in full
         force all necessary licenses, approvals and consents.

2.       PURCHASE AND SALE OF SECURITIES.

         American shall place all orders for the purchase and sale of portfolio
         securities for accounts of the Company and its subsidiaries with
         brokers or dealers selected by American and shall seek to execute
         portfolio transactions on terms which are advantageous to Company and
         its subsidiaries in selecting brokers or dealers to execute
         transactions. American shall not be obligated to solicit competitive
         bids or seek the lowest available commission cost. All trades by
         American of portfolio securities of Company shall be reported to the
         Company and its subsidiaries by 3:00 p.m. on the first business day
         following the trade.

3.       INVESTMENT FEES; EXPENSES.

         3.1. Company shall pay to American an annual fee for investment
         services rendered under this Agreement equal to .17% (seventeen basis
         points) of assets under management. The amount of assets under
         management shall be determined by determining the market value as shown
         on IDSI pricing tape of the portfolio securities; provided, however, in
         the event that any asset under management is not included on the IDSI
         pricing tape, the market value of such asset shall be valued as
         mutually agreed upon by Company and American. The fee shall be computed
         and paid on a quarterly basis measured as of the end of the preceding
         calendar quarter. The quarterly portion of each such fee shall be paid
         within ten (10) days after the end of each calendar quarter or portion
         thereof in which services are rendered under this Agreement.

         3.2. American shall furnish at its own expense necessary executive and
         other personnel for providing investment services to Company and its
         subsidiaries. Company and its subsidiaries shall be responsible for the
         expenses of (a) brokerage commissions, issue and transfer taxes and
         other costs in connection with securities transactions to which Company
         and its subsidiaries are a party, including any portion of such
         commissions attributable to research and brokerage services, (b) taxes
         payable by Company and its subsidiaries to federal, state and other
         governmental agencies, and (c) custodial fees and expenses.

4.       REPORTS AND RECORDS.

         4.1. American shall maintain adequate records relating to the
         furnishing of investment services under this Agreement, including those
         with respect to the acquisition and disposition of securities. American
         shall provide to Company and its subsidiaries such oral or written
         reports as to its services provided under this Agreement as Company and
         its subsidiaries shall reasonably require.

         4.2. All records maintained pursuant to this Agreement shall be deemed
         the property of Company and its subsidiaries and shall be subject to
         examination by Company and its subsidiaries and by persons authorized
         by it, or by governmental authorities, at all times upon

                                       2
<PAGE>

         reasonable notice. Except as expressly authorized in this Agreement or
         directed by Company in writing, American shall keep confidential such
         records and other information obtained by reason of this Agreement.
         Upon termination of this Agreement, American shall promptly return all
         such records to Company.

5.       NON-EXCLUSIVITY OF SERVICES.

         The services of American to be provided hereunder are not to be deemed
         exclusive and American shall be free to provide similar services for
         its own account and the accounts of others, provided that such services
         do not materially interfere with services to be rendered hereunder.

6.       LIABILITY; INDEMNIFICATION.

         Neither American nor any of its directors, officers or employees or
         other persons affiliated with American shall have any liability
         hereunder for any act, omission, misstatement or error in judgment in
         the course of, or in connection with, providing investment advisory
         services under this Agreement, or for any losses that may be sustained
         from such investment advisory services, and Company shall indemnify and
         hold harmless American and its directors, officers, employees and other
         affiliated persons from and against any and all liability, claims and
         damages arising from or in connection with providing such services
         hereunder; provided, however, that the foregoing shall not relieve
         American or any of such other persons from liability, or require the
         Company to provide any indemnity, for gross negligence, willful
         misfeasance or illegal conduct in providing such services.

7.       TERMINATION; RENEGOTIATION.

         This Agreement shall remain in effect for a period of five (5) years
         from the date it is effective and thereafter may be terminated by any
         party hereto at any time upon ninety (90) days written notice to the
         other party's normal business address. Upon termination of this
         Agreement, Company shall pay pro rata any investment fees due for any
         portion of a calendar quarter within ten (10) days following the date
         of termination.
