      any premium or interest on the debt securities will be determined;

    - any addition to or change in the events of default applicable to any of
      the debt securities and any change in the right of the Trustee or the
      holders to declare the principal amount of any of the debt securities due
      and payable;

    - any addition to or change in the covenants in the Indenture;

    - the applicability of or any change in the subordination provisions of the
      Indenture for a series of debt securities; and

    - any other terms of the debt securities inconsistent with the provisions of
      the Indenture.

EXCHANGE, REGISTER AND TRANSFER

    The debt securities of each series will be issuable only in fully registered
form without coupons.

    The debt securities may be presented for exchange, registered and
transferred in the manner, at the places and subject to the restrictions set
forth in the debt securities and the relevant prospectus supplement. Subject to
the limitations noted in the Indenture, you will not have to pay for such
services, except for any taxes or other governmental charges associated with
such services. You may transfer any debt securities in bearer form and the
associated coupons, if any, by delivering them.

                                       4

GLOBAL SECURITIES

    We may issue registered debt securities of a series in the form of one or
more fully registered global debt securities (each "registered global security")
that we will deposit with a depositary (or with a nominee of a depositary)
identified in the prospectus supplement relating to such series and registered
in the name of the depositary (or a nominee). In such a case, we will issue one
or more registered global securities. The face of such registered global
securities will set forth the aggregate principal amount of the series of debt
securities that such global registered securities represent. The depositary (or
its nominee) will not transfer any registered global security unless and until
it is exchanged in whole or in part for debt securities in definitive registered
form, except that:

    - the depositary may transfer the whole registered global security to a
      nominee;

    - the depositary's nominee may transfer the whole registered global security
      to the depositary;

    - the depositary's nominee may transfer the whole registered global security
      to another of the depositary's nominees; and

    - the depositary (or its nominee) may transfer the whole registered global
      security to its (or its nominee's) successor.

    The Depository Trust Company, which may be a depositary, currently accepts
only debt securities that are denominated in U.S. dollars.

DEPOSITARY ARRANGEMENTS

    We will describe the specific terms of the depositary arrangement with
respect to any portion of a series of debt securities to be represented by a
registered global security in the prospectus supplement relating to such series.
We anticipate that the following provisions will apply to all depositary
arrangements.

    Generally, ownership of beneficial interests in a registered global security
will be limited to persons that have accounts with the depositary for such
registered global security ("participants") or persons that may hold interests
through participants. Upon the issuance of a registered global security, the
depositary will credit, on its book-entry registration and transfer system, the
participants' accounts with the respective principal amounts of the debt
securities represented by such registered global security that are beneficially
owned by such participants.

    Any dealers, underwriters or agents participating in the distribution of
such debt securities will designate the accounts to credit. For participants,
the depositary will maintain the only record of their ownership of a beneficial
interest in the registered global security and they will only be able to
transfer such interests through the depositary's records. For people who hold
through a participant, the relevant participant will maintain such records for
beneficial ownership and transfer. The laws of some states may require that
certain purchasers of securities take physical delivery of such securities in
definitive form. Such limits and such laws may impair the ability to own,
transfer or pledge beneficial interests in registered global securities.

    So long as the depositary (or its nominee) is the record owner of a
registered global security, such depositary (or its nominee) will be considered
the sole owner or holder of the debt securities represented by such registered
global security for all purposes under the Indenture. Except as set forth below,
owners of beneficial interests in a registered global security will not be
entitled to have the debt securities represented by such registered global
security registered in their names, and will not receive or be entitled to
receive physical delivery of such debt securities in definitive form and will
not be considered the owners or holders under the Indenture. Accordingly, each
person owning a beneficial interest in a registered global security must rely on
the procedures of the depositary and, if such person is not a participant, on
the procedures of the participant through which such person owns its interest,
to exercise any rights of a holder under the Indenture. We understand that under
existing industry practices, if we request any action of holders or if any owner
of a beneficial interest in a registered global security desires to give or take
any action allowed under the Indenture, the depositary would authorize the
participants holding the relevant beneficial interests to give or take such
action, and such participants would authorize beneficial owners

                                       5

owning through such participants to give or take such action or would otherwise
act upon the instruction of beneficial owners holding through them.

INTEREST AND PREMIUM

    Payments of principal, premium, if any, and any interest on debt securities
represented by a registered global security registered in the name of a
depositary (or its nominee) will be made to the depositary (or its nominee) as
the registered owner of such registered global security. We and our agents will
have no responsibility or liability for any aspect of the records relating to or
payments made on account of beneficial ownership interests in any registered
global security or for maintaining, supervising or reviewing any records
relating to such beneficial ownership interests, and neither will the trustee
and its agents.

    We expect that the depositary for any debt securities represented by a
registered global security, upon receipt of any payment of principal, premium,
if any, or any interest in respect of such registered global security, will
immediately credit participants' accounts with payments in amounts proportionate
to their respective beneficial interests in such registered global security as
shown on the depositary's records. We also expect that payments by participants
to owners of beneficial interests in such registered global security held
through such participants will be governed by standing customer instructions and
customary practices, as is now the case with securities held for the accounts of
customers in bearer form or registered in "street name," and will be the
responsibility of such participants.

WITHDRAWAL OF DEPOSITARY

    If the depositary for any debt securities represented by a registered global
security notifies us that it is unwilling or unable to continue as depositary or
ceases to be eligible under applicable law, and a successor depositary is not
appointed within 90 days, debt securities in definitive form will be issued in
exchange for the relevant registered global security. In addition, we may at any
time and in our sole discretion determine not to have any of the debt securities
of a series represented by one or more registered global securities and, in such
event, debt securities of such series in definitive form will be issued in
exchange for all of the registered global security or registered global
securities representing such debt securities. Any debt securities issued in
definitive form in exchange for a registered global security will be registered
in such name or names that the depositary gives to the trustee. We expect that
such instructions will be based upon directions received by the depositary from
participants with respect to ownership of beneficial interests in such
registered global security.

PAYMENT AND PAYING AGENTS

    Unless the applicable prospectus supplement indicates otherwise, payment of
interest on a debt security on any interest payment date will be made to the
person in whose name such debt security is registered at the close of business
on the regular record date for such interest payment.

    Unless the applicable prospectus supplement indicates otherwise, principal
of and any premium and interest on the debt securities will be payable at the
office of the paying agent designated by us. However, we may elect to pay
interest by check mailed to the address of the person entitled to such payment
at the address appearing in the security register. Unless otherwise indicated in
the applicable prospectus supplement, the corporate trust office of the Trustee
in the City of Cincinnati will be designated as our sole paying agent for
payments with respect to debt securities of each series. Any other paying agents
initially designated by us for the debt securities of a particular series will
be named in the applicable prospectus supplement. We may at any time designate
additional paying agents or rescind the designation of any paying agent or
approve a change in the office through which any paying agent acts, except that
we will be required to maintain a paying agent in each place of payment for the
debt securities of a particular series.

    All moneys paid by us to a paying agent for the payment of the principal of
or any premium or interest on any debt security which remain unclaimed at the
end of 18 months after such principal, premium or interest has become due and
payable will be repaid to us, and the holder of such debt security thereafter
may look only to us for payment.

                                       6

CONSOLIDATION, MERGER, AND SALE OF ASSETS

    The Indenture does not contain any provision that restricts our ability to
merge or consolidate with or into any other corporation, sell or convey all or
substantially all of our assets to any person, firm or corporation or otherwise
engage in restructuring transactions, provided that the successor corporation
assumes due and punctual payment of principal or premium, if any, and interest
on the debt securities.

EVENTS OF DEFAULT

    Each of the following is defined as an event of default under the Indenture
with respect to debt securities of any series:

    - failure to pay principal of or any premium on any debt security of that
      series when due;

    - failure to pay any interest on any debt security of that series when due,
      continued for 30 days;

    - failure to deposit any sinking fund payment, when due, in respect of any
      debt security of that series;

    - failure to perform any other of our covenants in the Indenture (other than
      a covenant included in the Indenture solely for the benefit of a series
      other than that series), continued for 90 days after written notice has
      been given by the Trustee, or the holders of at least 35% in principal
      amount of the outstanding debt securities of that series, as provided in
      the Indenture; and

    - certain events of bankruptcy, insolvency or reorganization.

    If an event of default (other than a bankruptcy, insolvency or
reorganization event of default) with respect to the debt securities of any
series at the time outstanding shall occur and be continuing, either the Trustee
or the holders of at least 35% in aggregate principal amount of the outstanding
debt securities of that series by notice as provided in the Indenture may
declare the principal amount of the debt securities of that series to be due and
payable immediately. If a bankruptcy, insolvency or reorganization event of
default with respect to the debt securities of any series at the time
outstanding shall occur, the principal amount of all the debt securities of that
series will automatically, and without any action by the Trustee or any holder,
become immediately due and payable. After any such acceleration, but before a
judgment or decree based on acceleration, the holders of a majority in aggregate
principal amount of the outstanding debt securities of that series may, under
certain circumstances, rescind and annul such acceleration if all events of
default, other than the non-payment of accelerated principal, have been cured or
waived as provided in the Indenture. For information as to waiver of defaults,
see "Modification and Waiver."

    Subject to the provisions of the Indenture relating to the duties of the
Trustee in case an event of default shall occur and be continuing, the Trustee
will be under no obligation to exercise any of its rights or powers under the
Indenture at the request or direction of any of the holders, unless such holders
shall have offered to the Trustee reasonably satisfactory indemnity. Subject to
such provisions for the indemnification of the Trustee, the holders of a
majority in principal amount of the outstanding debt securities of any series
will have the right to direct the time, method and place of conducting any
proceeding for any remedy available to the Trustee, or exercising any trust or
power conferred on the Trustee, with respect to the debt securities of that
series.

    No holder of a debt security of any series will have any right to institute
any proceeding with respect to the Indenture, or for the appointment of a
receiver or a trustee, or for any other remedy thereunder, unless:

    (i) such holder has previously given to the Trustee written notice of a
        continuing event of default with respect to the debt securities of that
        series;

    (ii) the holders of at least 35% in aggregate principal amount of the
         outstanding debt securities of that series have made written request,
         and such holder or holders have offered reasonably satisfactory
         indemnity, to the Trustee to institute such proceeding as trustee; and

                                       7

   (iii) the Trustee has failed to institute such proceeding, and has not
         received from the holders of a majority in aggregate principal amount
         of the outstanding debt securities of that series a direction
         inconsistent with such request, within 60 days after such notice,
         request and offer.   However, such limitations do not apply to a suit
         instituted by a holder of a debt security for the enforcement of
         payment of the principal of or any premium or interest on such debt
         security on or after the applicable due date specified in such debt
         security.

    We will be required to furnish to the Trustee annually a statement by
certain of our officers as to whether or not we, to our knowledge, are in
default in the performance or observance of any of the terms, provisions and
conditions of the Indenture and, if so, specifying all such known defaults.

MODIFICATION AND WAIVER

    Modifications and amendments of the Indenture may be made by us and the
Trustee with the consent of the holders of not less than a majority in aggregate
principal amount of the outstanding debt securities of each series affected by
such modification or amendment; provided, however, that no such modification or
amendment may, without the consent of the holder of each outstanding debt
security affected thereby:

    - change the stated maturity of the principal of, or any installment of
      principal of or interest on, any debt security;

    - reduce the principal amount of, or any premium or interest on, any debt
      security;

    - reduce the amount of principal of an original issue discount security or
      any other debt security payable upon acceleration of the maturity thereof;

    - change the place or currency of payment of principal of or any premium or
      interest on any debt security;

    - affect the applicability of the subordination provisions to any debt
      security;

    - impair the right to institute suit for the enforcement of any payment on
      or with respect to any debt security; or

    - reduce the percentage in principal amount of outstanding debt securities
      of any series, the consent of whose holders is required for modification
      or amendment of the Indenture, reduce the percentage in principal amount
      of outstanding debt securities of any series necessary for waiver of
      compliance with certain provisions of the Indenture or for waiver of
      certain defaults or modify such provisions with respect to modification
      and waiver.

    The holders of not less than a majority in aggregate principal amount of the
outstanding debt securities of any series may waive our compliance with certain
restrictive provisions of the Indenture.   The holders of a majority in
principal amount of the outstanding debt securities of any series may waive any
past default under the Indenture, except a default in the payment of principal,
premium, or interest and certain covenants and provisions of the Indenture which
cannot be amended without the consent of the holder of each outstanding debt
security of such series affected.

    Except in certain limited circumstances, we will be entitled to set any day
as a record date for the purpose of determining the holders of outstanding debt
securities of any series entitled to give or take any direction, notice,
consent, waiver, or other action under the Indenture, in the manner and subject
to the limitations provided in the Indenture. In certain limited circumstances,
the Trustee will be entitled to set a record date for action by holders. If a
record date is set for any action to be taken by holders of a particular series,
such action may be taken only by persons who are holders of outstanding debt
securities of that series on the record date. To be effective, such action must
be taken by holders of the requisite principal amount of such debt securities
within a specified period following the record date. For any particular record
date, this period will be 180 days or such other shorter period as we may
specify (or the Trustee, if it set the record date), and may be shortened or
lengthened (but not beyond 180 days) from time to time.

                                       8

DEFEASANCE AND COVENANT DEFEASANCE

    Under the Indenture, we may elect to have the provisions of the Indenture
relating to defeasance and discharge of indebtedness or the provisions relating
to defeasance of certain restrictive covenants applied with respect to the debt
securities of any series.

    DEFEASANCE AND DISCHARGE.  If we elect to have the provisions of the
Indenture relating to defeasance and discharge of indebtedness applied to any
debt securities, we will be discharged from all our obligations with respect to
such debt securities (except for certain obligations to exchange or register the
transfer of debt securities, to replace stolen, lost or mutilated debt
securities, to maintain paying agencies and to hold moneys for payment in trust)
upon the deposit in trust for the benefit of the holders of such debt securities
of money or U.S. Government Obligations, or both, which, through the payment of
principal and interest in respect thereof in accordance with their terms, will
provide money in an amount sufficient to pay the principal of and any premium
and interest on such debt securities on the respective stated maturities in
accordance with the terms of the Indenture and such debt securities. Such
defeasance or discharge may occur only if, among other things, we have delivered
to the Trustee an opinion of counsel to the effect that we have received from,
or there has been published by, the United States Internal Revenue Service a
ruling, or there has been a change in tax law, in either case to the effect that
holders of such debt securities will not recognize gain or loss for federal
income tax purposes as a result of such deposit, defeasance, and discharge and
will be subject to federal income tax on the same amount, in the same manner and
at the same times as would have been the case if such deposit, defeasance and
discharge were not to occur.

    DEFEASANCE OF CERTAIN COVENANTS.  If we elect to have the provisions of the
Indenture relating to defeasance of certain covenants applied to any debt
securities, we may omit to comply with certain restrictive covenants that may be
described in the applicable prospectus supplement, and the occurrence of certain
events of default, which are described above (with respect to such restrictive
covenants) under "events of default" and any that may be described in the
applicable prospectus supplement, will be deemed not to be or result in an event
of default, in each case with respect to such debt securities. In order to
exercise such option, we will be required to deposit, in trust for the benefit
of the holders of such debt securities, money or U.S. Government Obligations, or
both, which, through the payment of principal and interest in respect thereof in
accordance with their terms, will provide money in an amount sufficient to pay
the principal of and any premium and interest on such debt securities on the
respective stated maturities in accordance with the terms of the Indenture and
such debt securities. We will also be required, among other things, to deliver
to the Trustee an opinion of counsel to the effect that holders of such debt
securities will not recognize gain or loss for federal income tax purposes as a
result of such deposit and defeasance of certain obligations and will be subject
to federal income tax on the same amount, in the same manner and at the same
times as would have been the case if such deposit and defeasance were not to
occur. In the event that we exercised this option with respect to any debt
securities and such debt securities were declared due and payable because of the
occurrence of any event of default, the amount of money and U.S. Government
Obligations so deposited in trust would be sufficient to pay amounts due on such
debt securities at the time of their respective stated maturities but may not be
sufficient to pay amounts due on such debt securities upon any acceleration
resulting from such event of default. In such case, we would remain liable for
such payments..

TITLE

    ULH&P and the Trustee, and any agent of ULH&P or the Trustee may treat the
person in whose name a debt security is registered as the absolute owner thereof
(whether or not such debt security may be overdue) for the purpose of making
payment and for all other purposes.

GOVERNING LAW

    The Indenture and the debt securities will be governed by, and construed in
accordance with, the laws of the State of New York.

                                       9

CONCERNING THE TRUSTEE

    Fifth Third Bank is the Trustee under the Indenture. Fifth Third Bank also
acts as Trustee for certain unsecured debt securities of our parent, The
Cincinnati Gas & Electric Company, and certain of our other affiliates,
including Cinergy Corp., Cinergy Global Resources, Inc. and PSI Energy, Inc.
Fifth Third Bank also acts as Trustee for certain pollution control revenue
bonds of Cincinnati Gas & Electric and PSI, and acts as registrar for the common
stock of Cinergy and for the preferred stock of Cincinnati Gas & Electric and
PSI. Fifth Third Bank makes loans to, acts as depositary for, and, in the normal
course of business, also performs other services for ULH&P, Cincinnati Gas &
Electric and PSI.

                              PLAN OF DISTRIBUTION

    We may sell the debt securities directly to purchasers or indirectly through
underwriters, dealers or agents. The name of any such underwriters, dealers or
agents will be set forth in the relevant prospectus supplement. We will also set
forth in the relevant prospectus supplement:

    - the terms of the offering of the debt securities;

    - the proceeds we receive from such a sale;

    - any underwriting discounts and other items constituting underwriters'
      compensation;

    - any initial public offering price;

    - any discounts or concessions allowed or reallowed or paid to dealers; and

    - any securities exchanges on which we may list the debt securities.

    We may distribute the debt securities from time to time in one or more
transactions at:

    - a fixed price;

    - prices that may be changed;

    - market prices at the time of sale;

    - prices related to prevailing market prices; and

    - negotiated prices.

    We will describe the method of distribution in the relevant prospectus
supplement.

    If we use underwriters with respect to a series of debt securities, we will
set forth in the relevant prospectus supplement:

    - the name of the managing underwriter, if any;

    - the name of any other underwriters; and

    - the terms of the transaction, including any underwriting discounts and
      other items constituting compensation of the underwriters and dealers, if
      any.

    The underwriters will acquire any debt securities for their own accounts and
they may resell the debt securities from time to time in one or more
transactions, including negotiated transactions, at a fixed public offering
price and at varying prices determined at the time of sale.

    Any initial public offering price and any discounts or concessions allowed
or reallowed or paid to dealers may be changed from time to time. We anticipate
that any underwriting agreement pertaining to any debt securities will:

    - entitle the underwriters to indemnification by us against certain civil
      liabilities under the Securities Act, or to contribution with respect to
      payments that the underwriters may be required to make related to any such
      civil liability;

                                       10

    - subject the obligations of the underwriters to certain conditions
      precedent; and

    - obligate the underwriters to purchase all debt securities offered in a
      particular offering if any such debt securities are purchased.

    In connection with an offering of debt securities, underwriters may engage
in transactions that stabilize, maintain or otherwise affect the price of the
debt securities. Specifically, underwriters may:

    - overallot in connection with the offering, creating a syndicate short
      position;

    - bid for, and purchase, debt securities in the open market to cover
      syndicate short positions;

    - bid for, and purchase, debt securities in the open market to stabilize the
      price of the debt securities; and

    - reclaim selling concessions allowed for distributing the debt securities
      in the offering if the syndicate repurchases previously distributed debt
      securities in syndicate covering transactions, in stabilization
      transactions or otherwise.

    Any of these activities may stabilize or maintain the market price of the
debt securities above independent market levels. Underwriters are not required
to engage in these activities, and may end any of these activities at any time.

    If we use a dealer in an offering of debt securities, we will sell such debt
securities to the dealer, as principal. The dealer may then resell the debt
securities to the public at varying prices to be determined by such dealer at
the time of resale. We will set forth the name of the dealer and the terms of
the transaction in the prospectus supplement.

    If we use an agent in an offering of debt securities, we will name the agent
and describe the terms of the agency in the relevant prospectus supplement.
Unless we indicate otherwise in the prospectus supplement, we will require an
agent to act on a best efforts basis for the period of its appointment.

    Dealers and agents named in a prospectus supplement may be considered
underwriters of the debt securities described in the prospectus supplement under
the Securities Act. We may indemnify them against certain civil liabilities
under the Securities Act. In the ordinary course of business, we may engage in
transactions with underwriters, dealers and agents and they may perform services
for us.

    We may solicit offers to purchase debt securities and make sales directly to
institutional investors or others who may be considered underwriters under the
Securities Act with respect to such sales. We will describe the terms of any
such offer in the relevant prospectus supplement.

    If we authorize underwriters or other agents to solicit offers to purchase
debt securities from institutional investors pursuant to contracts providing for
payment and delivery at a future date, we will indicate that we are doing so in
the relevant prospectus supplement. We must approve all purchasers under such
contracts; the institutional investors may include commercial and savings banks,
insurance companies, pension funds, investment companies, educational and
charitable institutions and others. We will not subject the obligations of such
purchasers to any conditions except that:

    - we will not allow such purchases if they violate the laws of any
      jurisdiction to which a proposed purchaser is subject; and

    - if we are also selling the debt securities to underwriters, we will not
      sell to the underwriters subject to delayed delivery.

Underwriters and other agents will not be responsible for the validity or
performance of such contracts providing for payment and delivery at a future
date.

    We will set forth in the relevant prospectus supplement the anticipated
delivery date of debt securities and the prospectus delivery obligations of
dealers.

                                       11

                                 LEGAL MATTERS

    The validity of the debt securities will be passed upon for us by Taft,
Stettinius & Hollister LLP, Cincinnati, Ohio.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS

    Sections 271B.8-500 to 271B.8-580 of the Kentucky Revised Statutes provide
that a corporation may indemnify an individual made a party to any threatened,
pending, or completed action, suit, or proceeding whether civil, criminal,
administrative, or investigative because he is or was a director or any
individual who, while a director, is or was serving at the corporation's request
as a director, officer, partner, trustee, employee, or agent of another foreign
or domestic corporation, partnership, joint venture, trust, employee benefit
plan, or other enterprise, against a judgment, settlement, penalty, fine, or
reasonable expenses (including counsel fees) incurred with respect to a
proceeding, if he conducted himself in good faith and he reasonably believed, in
the case of conduct in his official capacity with the corporation, that his
conduct was in its best interest, and in all other cases, that his conduct was
at least not opposed to its best interests, and, in the case of any criminal
proceeding, he had no reasonable cause to believe his conduct was unlawful.
Unless limited by its articles of incorporation, a corporation shall indemnify a
director who was wholly successful on the merits or otherwise, in the defense of
any proceeding to which he was a party because he is or was a director, against
reasonable expenses incurred by him in connection with the proceeding. Under
Section 271B.8-510, a corporation may not indemnify a director in connection
with a proceeding by or in the right of the corporation in which the director
was adjudged liable to the corporation, or in connection with any other
proceeding charging improper personal benefit to him, whether or not involving
action in his official capacity, in which he was adjudged liable on the basis
that personal benefit was improperly received by him. Indemnification in
connection with a proceeding by or in the right of the corporation is limited to
reasonable expenses incurred in connection with the proceeding.

    Section 271B.8-560 provides that a corporation may indemnify an officer,
employee, or agent of the corporation who is not a director to the same extent
as to a director, and may indemnify and advance expenses to such an individual
who is not a director to the extent, consistent with public policy, that may be
provided by its articles of incorporation, bylaws, general or specific action of
its board of directors, or contract.

    Section 271B.8-570 authorizes a corporation to purchase and maintain
insurance on behalf of an individual who is or was a director, officer,
employee, or agent of the corporation, or who, while such director, officer,
employee, or agent, is or was serving at the request of the corporation as a
director, officer, partner, trustee, employee, or agent of another foreign or
domestic corporation, partnership, joint venture, trust, employee benefit plan,
or other enterprise, against liability asserted against or insured by him in
that capacity or arising from his status as a director, officer, employee, or
agent, whether or not the corporation would have power to indemnify him against
the same liability.

                                      II-1

    Section 271B.8-580 provides that such indemnification shall not be deemed
exclusive of any other rights to which those seeking indemnification may be
entitled under any bylaw, agreement, vote of shareholders, or disinterested
directors or otherwise, both as to action in his official capacity and as to
action in another capacity while holding such office.

    Union Light's By-Laws provide indemnification to its directors, officers,
employees, and agents to the fullest extent authorized by Kentucky law.

    Union Light maintains an insurance policy covering its directors and
officers against certain civil liabilities, including liabilities under the
Securities Act of 1933.

    The underwriters, dealers or agents, if any, will agree under certain
circumstances to indemnify the directors and certain officers of Union Light
against certain civil liabilities, principally liabilities under the Securities
Act of 1933.

ITEM 17. UNDERTAKINGS

    (a) The Registrant undertakes:

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

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

                                      II-2

           (ii) to reflect in the prospectus any facts or events arising after
       the effective date of the registration statement (or the most recent
       post-effective amendment to the registration statement) which,
       individually or in the aggregate, represent a fundamental change in the
       information contained in the registration statement. Notwithstanding the
       foregoing, any increase or decrease in volume of securities offered (if
       the total dollar value of securities offered would not exceed that which
       was registered) and any deviation from the low or high end of the
       estimated maximum offering range may be reflected in the form of
       prospectus filed with the Securities and Exchange Commission pursuant to
       Rule 424(b) under the Securities Act of 1933 if, in the aggregate, the
       changes in volume and price represent no more than a 20% change in the
       maximum aggregate offering price set forth in the "Calculation of
       Registration Fee" table in the effective registration statement; and

           (iii) to include any material information on the plan of distribution
       not previously disclosed in the registration statement or any material
       change to such information in the registration statement;

       PROVIDED, HOWEVER, that the undertakings set forth in paragraph (i) and
       (ii) above do not apply if the information required to be included in a
       post-effective amendment by those paragraphs is contained in periodic
       reports filed by the registrant pursuant to section 13 or section 15(d)
       of the Securities Exchange Act of 1934 that are incorporated by reference
       in this registration statement.

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

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

    (b) The undersigned registrant hereby understands that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to section 13(a) or section 15(d) of the
Securities Exchange Act of 1934 that is incorporated by reference in the
registration statement shall be deemed to be a new registration statement
relating to the securities offered herein, and the offering of such securities
at that time shall be deemed to be the initial BONA FIDE offering thereof.

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

                                      II-3

                                   SIGNATURES

    Pursuant to the requirements of the Securities Act of 1933, the registrant
certifies that it has reasonable grounds to believe that it meets all of the
requirements for filing on Form S-3 and has duly caused this Registration
Statement to be signed on its behalf by the undersigned, thereunto duly
authorized, in the City of Cincinnati, State of Ohio, on July 21, 1999.
