PROSPECTUS

                                    DPL INC.

               OFFER TO EXCHANGE ITS 8 1/4% SENIOR NOTES DUE 2007

                           TERMS OF THE EXCHANGE OFFER

          We are offering to exchange up to $425,000,000 of our new 8 1/4%
Senior Exchange Notes due 2007 for up to $425,000,000 of our existing 8 1/4%
Senior Notes due 2007. Throughout this prospectus we refer to the 8 1/4% Senior
Notes due 2007 as "old notes" and the 8 1/4% Senior Exchange Notes due 2007 as
"exchange notes."

          We are offering to issue the exchange notes to satisfy our obligations
contained in the registration rights agreement entered into when the old notes
were sold in transactions exempt from registration under the Securities Act.

          The terms of the exchange notes will be substantially identical to the
terms of the old notes, except that the exchange notes will be registered and
the transfer restrictions, registration rights and provisions for additional
interest relating to the old notes will not apply to the exchange notes. There
is no existing market for the exchange notes, and DPL does not intend to apply
for their listing on any securities exchange.

          All old notes that are validly tendered and not validly withdrawn will
be exchanged.

          The exchange of old notes for exchange notes will not be a taxable
exchange for U.S. federal income tax purposes.

          To exchange your old notes for the exchange notes:

          o    You must complete and send the letter of transmittal that
               accompanies this prospectus to Bank One Trust Company, National
               Association, the exchange agent, by 5:00 p.m., New York time, on
                       , 2000, unless the exchange offer is extended.
               --------

          o    If your old notes are held in book-entry form at The Depository
               Trust Company, you must instruct DTC, through your signed letter
               of transmittal, that you wish to exchange your old notes for
               exchange notes. When the exchange offer closes, your DTC account
               will be changed to reflect your exchange of old notes for
               exchange notes.

          o    Tenders of old notes may be withdrawn at any time prior to the
               expiration of the exchange offer.

You should read the section called "The Exchange Offer" for additional
information on how to exchange your old notes for exchange notes.

          Neither the Securities and Exchange Commission nor any state
securities commission has approved or disapproved of these securities or
determined that this prospectus is truthful or complete. Any representation to
the contrary is a criminal offense.

THE EXCHANGE OFFER........... We are offering to issue the exchange notes in
                              exchange for a like principal amount of the
                              outstanding 8 1/4% Senior Notes due 2007, issued
                              by us in a private placement on March 1, 2000. We
                              are offering to issue the exchange notes to
                              satisfy our obligations contained in the

                                       6



RESALES OF EXCHANGE NOTES.... Based on Commission no-action letters, we believe
                              that after the exchange offer you may offer and
                              sell the exchange notes without registration under
                              the Securities Act so long as:

                                        - You acquired the exchange notes in the
                                        ordinary course of business.

                                        - When the exchange offer begins you do
                                        not have an arrangement with another
                                        person to participate in a distribution
                                        of the exchange notes.

                                        - You are not engaged in a distribution
                                        of, nor do you intend to distribute, the
                                        exchange notes.

                              When you tender the outstanding notes, we will ask
                              you to represent to us that:

                                        - You are not an affiliate of DPL.

                                        - You will acquire the exchange notes in
                                        the ordinary course of business.

                                        - When the exchange offer begins you are
                                        not engaged in, nor do you have plans
                                        with another person to be engaged in, a
                                        distribution of the exchange notes.

                              If you are unable to make these representations,
                              you will be required to comply with the
                              registration and prospectus delivery requirements
                              under the Securities Act in connection with a
                              resale transaction.

                              If you are a broker-dealer and receive exchange
                              notes for your own account, you must acknowledge
                              that you will deliver a prospectus if you resell
                              the exchange notes. By acknowledging your intent
                              and delivering a prospectus you will not be deemed
                              to admit that you are an "underwriter" under the
                              Securities Act. You may use this prospectus as it
                              is amended from time to time when you resell
                              exchange notes which were acquired from
                              market-making or trading activities. For a year
                              after the expiration date we will make this
                              prospectus available to any broker-dealer in
                              connection with such a resale. See "Plan of
                              Distribution."

CONDITIONS TO THE
EXCHANGE OFFER............... The exchange offer is subject to conditions, some
                              of which we may waive. These conditions are more
                              fully described later in this prospectus under
                              "The Exchange Offer-Certain Conditions to the

                                       7



PROCEDURES FOR
TENDERING OLD NOTES.......... If you wish to participate in the exchange offer,
                              you must complete, sign and date the accompanying

                              it or deliver it to the exchange agent along with
                              any necessary documentation. Instructions and the
                              address of the exchange agent are on the letter of
                              transmittal and in this prospectus. See "The
                              Exchange Offer - Procedures for Tendering Old
                              Notes- Exchange Agent." You may also effect a
                              tender of outstanding notes pursuant to the
                              procedures for book-entry transfer as described in
                              this prospectus. See "Exchange Offer - Procedures
                              for Tendering Old Notes."

MATURITY DATE................ The exchange notes will mature on March 1, 2007

INTEREST PAYMENT DATES....... Interest on the exchange notes is payable on
                              March 1 and September 1 of each year, commencing
                              September 1, 2000.

INTEREST ACCRUAL............. Interest on the exchange notes will accrue from
                              the last interest payment date to which we paid
                              interest on the old notes.

ABSENCE OF PUBLIC MARKET
FOR THE EXCHANGE NOTES....... We do not intend to apply for a listing of the
                              exchange notes on any securities exchange. We do
                              not know if an active public market for the
                              exchange notes will develop or, if developed, will
                              continue. If an active public market does not
                              develop or is not maintained, the market price and
                              liquidity of the exchange notes may be adversely
                              affected. We cannot make any assurances regarding
                              the liquidity of the market for the exchange
                              notes, the ability of holders to sell their
                              exchange notes or the price at which holders may
                              sell their exchange notes.

OPTIONAL REDEMPTION.......... We may redeem the exchange notes prior to their
                              maturity at a redemption price equal to the sum of
                              (a) the principal of the exchange notes being
                              redeemed plus accrued interest thereon to the
                              redemption date plus (b) a make-whole amount. See
                              "Description of Exchange Notes--Redemption."

MAKE-WHOLE AMOUNT............ The make-whole amount equals the excess, if any,
                              of

                              o the sum of the present values of the remaining
                              scheduled payments of the principal amount and
                              interest on the exchange notes, exclusive of
                              interest paid to the date of redemption, from the
                              redemption date to the stated maturity of the
                              exchange notes, computed by discounting these
                              payments, in each case, to the redemption date on
                              a semi-annual basis, assuming a 360-day year
                              consisting of twelve 30-day months, at the
                              then-current rate for treasury securities of an
                              equivalent maturity plus .35% over

                              o 100% of the principal amount of the exchange
                              notes to be redeemed. See "Description of Exchange
                              Notes--Redemption."

PRIORITY..................... The exchange notes will be unsecured obligations
                              and, so long as they are unsecured, will rank
                              equally with all of our other senior unsecured
                              indebtedness. The indenture under which we will
                              issue the exchange notes does not limit the amount
                              of debt we or any of our subsidiaries may incur.
                              Because we are a holding company that derives
                              substantially all of our income from our operating


                                       8



                              subsidiaries, the exchange notes will be
                              effectively subordinated to debt and preferred
                              stock at the subsidiary level. See "Description of
                              Exchange Notes-- General."

USE OF PROCEEDS.............. There will be no proceeds payable to us from the
                              issuance of the exchange notes pursuant to the
                              exchange offer.

FORM AND DENOMINATION........ We will issue the exchange notes in fully
                              registered form only in denominations of $1,000
                              and in integral multiples of $1,000. The exchange
                              notes will be represented by a registered global
                              certificate deposited with, or on behalf of, the
                              Depository Trust Company or its nominee. See
                              "Description of Exchange Notes-- Book-Entry,
                              Delivery and Form."

LIMITATION ON LIENS.......... We may not grant a lien on the capital shares of
                              Dayton Power and Light to secure our indebtedness
                              without similarly securing the exchange notes,
                              with certain exceptions. See "Description of
                              Exchange Notes--Limitation on Liens."

TENDERS, EXPIRATION DATE,
WITHDRAWAL................... The exchange offer will expire at 5:00 p.m. New
                              York City time on       , 2000, unless it is
                                                ------
                              extended. If you decide to exchange your old notes
                              for exchange notes, you must acknowledge that you
                              are not engaging in, and do not intend to engage
                              in, a distribution of the exchange notes. If you
                              decide to tender your old notes pursuant to the
                              exchange offer, you may withdraw them at any time
                              prior to      , 2000. If we decide for any reason
                                       -----
                              not to accept any old notes for exchange, your old
                              notes will be returned to you at our expense
                              promptly after the expiration or termination of
                              the exchange offer.

FAILURE TO TENDER OLD NOTES.. If you do not tender your old notes or we do not
                              accept your tender because, among other things,
                              you invalidly tendered your old notes, you will
                              not be entitled to any further registration rights
                              under the registration rights agreement, except
                              under limited circumstances. However, your old
                              notes will remain outstanding and entitled to the
                              benefits of the indenture.

MATERIAL UNITED STATES TAX
CONSEQUENCES................. Your exchange of old notes for exchange notes
                              pursuant to the exchange offer should not result
                              in any income, gain or loss to you for United
                              States federal income tax purposes. See "Material
                              United States Federal Income Tax Considerations."

                                 USE OF PROCEEDS

          We will not receive any proceeds from the issuance of the exchange
notes in exchange for the old notes tendered pursuant to the exchange offer. In
consideration for the issuance of the exchange notes as contemplated by this
prospectus, we will receive in exchange an identical principal amount of
outstanding notes, which have terms substantially identical to the exchange
notes. We will retire and cancel all of the outstanding notes surrendered in
exchange for the exchange notes, and such outstanding notes may note be
reissued.


                               THE EXCHANGE OFFER

PURPOSE AND EFFECT OF THE EXCHANGE OFFER; TERMS OF THE EXCHANGE OFFER

          We issued and sold the old notes on March 1, 2000 to the initial
purchaser in a private transaction not subject to the registration requirements
of the Securities Act. The initial purchaser then offered and sold the old notes
only

          o    to "Qualified Institutional Buyers" (as defined in Rule 144A
               under the Securities Act) in reliance on the exemption from the
               registration requirements of the Securities Act provided by Rule
               144A,

          o    to a limited number of institutional "Accredited Investors" (as
               defined in Rule 501(a)(1), (2), (3) or (7) under the Securities
               Act) that, prior to their purchase of old notes, executed and
               delivered to the initial purchaser a letter containing certain
               representations and agreements and

          o    outside the United States to non-U.S. persons in offshore
               transactions (as defined in Regulation S under the Securities
               Act) in compliance with Regulation S under the Securities Act.

          In connection with the sale of the old notes, we entered into a
registration rights agreement with the initial purchaser which obligated us to:

          o    file a registration statement with the Commission for an offer to
               exchange the old notes for the exchange notes;

          o    use our reasonable best efforts to cause the registration
               statement to be declared effective within 180 days after the
               issuance of the old notes;

          o    promptly after the registration statement has been declared
               effective, offer exchange notes in exchange for surrender of the
               old notes; and

          o    use our reasonable best efforts to keep the exchange offer open
               for at least 30 days after the date notice of the exchange offer
               has been mailed to the holders of the old notes.

The exchange notes have terms identical to the old notes, except that the
exchange notes do not have transfer restrictions or any terms relating to
registration rights and do not provide for the liquidated damages set forth in
the registration rights agreement payable by us in the event that we are unable
to fulfill certain of our obligations under the registration rights agreement. A
holder that tenders an old note pursuant to the exchange offer and does not
withdraw it will receive an exchange note in the same principal amount as the
tendered old note. Interest on each exchange note will accrue from the last
interest payment on the old note tendered. If no interest has been paid on the
old notes, interest will accrue from the date of issuance of the old notes.

PROCEDURES FOR TENDERING OLD NOTES

          The tender to us of old notes by a holder as set forth below and the
acceptance of the old notes by us will constitute a binding agreement between
the tendering holder and us upon the terms and subject to the conditions set
forth in this prospectus and in the accompanying letter of transmittal. Except
as set forth below, a holder who wishes to tender old notes for exchange


                                       11



pursuant to the exchange offer must transmit a properly completed and duly
executed letter of transmittal, including all other documents required by such
letter of transmittal, to Bank One Trust Company, National Association, who is
acting as our exchange agent, at the address set forth below under "Exchange
Agent" on or prior to the expiration date. In addition:

          o    certificates for such old notes must be received by the exchange
               agent along with the letter of transmittal; or

          o    a timely confirmation of a book-entry transfer of these old
               notes, if this procedure is available, into the exchange agent's
               account at DTC pursuant to the procedure for book-entry transfer
               described below, must be received by the exchange agent prior to
               the expiration date; or

          o    the holder must comply with the guaranteed delivery procedures
               described below.

          The method of delivery of old notes, letters of transmittal and all
other required documents is at the election and risk of the holders. If such
delivery is by mail, we recommend that you use registered mail, properly
insured, with return receipt requested. In all cases, sufficient time should be
allowed to assure timely delivery. No letters of transmittal or old notes should
be sent to DPL.

          Signatures on a letter of transmittal or a notice of withdrawal, as
the case may be, must be guaranteed unless the old notes surrendered for
exchange pursuant thereto are tendered:

          o    by a registered holder of the old notes who has not completed the
               box entitled "Special Issuance Instructions" or "Special Delivery
               Instructions" on the letter of transmittal; or

          o    for the account of an eligible institution.

          If signatures on a letter of transmittal or a notice of withdrawal, as
the case may be, are required to be guaranteed, such guarantees must be by an
eligible institution, which is a firm that is a member of a registered national
securities exchange or a member of the National Association of Securities
Dealers, Inc., or a commercial bank or trust company having an office or
correspondent in the United States. If old notes are registered in the name of a
person other than the person signing the letter of transmittal, the old notes
surrendered for exchange must be endorsed by, or be accompanied by a written
instrument or instruments of transfer or exchange, in satisfactory form as
determined by us in our sole discretion, duly executed by the registered holder
with the signature thereon guaranteed by an eligible institution.

          All questions as to the validity, form, eligibility (including time of
receipt) and acceptance of old notes tendered for exchange will be determined by
us in our sole discretion, and our determination will be final and binding on
all parties. We reserve the absolute right:

          o    to reject any and all tenders of any particular old notes not
               properly tendered or to not accept any particular old notes which
               acceptance might, in our judgment or the judgment of our counsel,
               be unlawful; and

          o    to waive any defects or irregularities or conditions of the
               exchange offer as to any particular old notes either before or
               after the expiration date (including the right to waive the
               ineligibility of any holder who seeks to tender old notes in the
               exchange offer).

          Unless waived, any defects or irregularities in connection with the
tender of old notes for exchange must be cured within such reasonable period of
time as we determine. Neither we, the exchange agent nor any other person will
be under any duty to give notification of any defect or irregularity with
respect to any tender of old notes for exchange, nor will we or any of them
incur any liability for failure to give such notification.


                                       12



TERMS OF THE EXCHANGE OFFER; PERIOD FOR TENDERING OLD NOTES

          Upon the terms and subject to the conditions set forth in this
prospectus and in the accompanying letter of transmittal, we will:

          o    accept for exchange old notes, which are properly tendered on or
               prior to the expiration date and not withdrawn as permitted
               below; and

          o    use our reasonable best efforts to keep the exchange offer open
               for not less than 30 days, or longer if required by applicable
               law, after the date notice of the exchange offer is mailed to the
               holders of the old notes.

          The term "expiration date" means 5:00 p.m., New York City time, on
       , 2000; provided, however, that if we, in our sole discretion, have
- -------
extended the period of time for which the exchange offer is open, the term
"expiration date" means the latest time and date to which the exchange offer is
extended.

          As of the date of this prospectus, $425,000,000 in aggregate principal
amount of the old notes were outstanding. The exchange offer is not conditioned
upon any minimum principal amount of old notes being tendered. This prospectus,
together with the letter of transmittal, is first being sent on or about the
date set forth on the cover page to all holders of old notes at the addresses
set forth in the security register maintained by the trustee.

          We expressly reserve the right:

          o    at any time or from time to time, to extend the period of time
               during which the exchange offer is open, and thereby delay
               acceptance of any old notes; and

          o    to amend or terminate the exchange offer, and not to accept for
               exchange any old notes not previously accepted for exchange, upon
               the occurrence of any of the conditions of the exchange offer
               specified below under "Certain Conditions to the Exchange Offer."

          We will give written notice of any extension, amendment,
non-acceptance or termination to the holders of the old notes as promptly as
practicable, such notice in the case of any extension to be issued by means of a
press release or other public announcement no later than 5:00 p.m., New York
City time, on the previous expiration date. Without limiting the manner in which
we may choose to make any public announcement and subject to applicable law, we
shall have no obligation to publish, advertise or otherwise communicate any such
public announcement other than by issuing a release to the Dow Jones News
Service.

          Old notes that are not tendered for exchange or are tendered but not
accepted in connection with the exchange offer will remain outstanding and be
entitled to the benefits of the indenture, but will not be entitled to any
further registration rights under the registration rights agreement, except
under limited circumstances. We intend to conduct the exchange offer in
accordance with the applicable requirements of the Exchange Act and the relevant
rules and regulations of the SEC.

          If the letter of transmittal is signed by a person or persons other
than the registered holder or holders of old notes, such old notes must be
endorsed or accompanied by appropriate powers of attorney, in either case signed
exactly as the name or names of the registered holder or holders that appear on
the old notes.

          By executing, or otherwise becoming bound by, a letter of transmittal,
each holder of the old notes, other than certain specified holders, will
represent that:

          o    it is not our affiliate;

          o    any exchange notes to be received by it were acquired in the
               ordinary course of its business; and


                                       13



          o    it has no arrangement with any person to participate in the
               distribution, within the meaning of the Securities Act, of the
               exchange notes.

          If the tendering holder is a broker-dealer that will receive exchange
notes for its own account in exchange for the old notes that were acquired as a
result of market-making activities or other trading activities, it will be
required to acknowledge that it will deliver a prospectus in connection with any
resale of such exchange notes. See "--Resale of the Exchange Notes."

ACCEPTANCE OF OLD NOTES FOR EXCHANGE; DELIVERY OF EXCHANGE NOTES

          Upon satisfaction or waiver of all of the conditions to the exchange
offer, we will accept, promptly after the expiration date, all old notes
properly tendered and will issue exchange notes promptly after acceptance of the
old notes. See "Certain Conditions to the Exchange Offer" below. For purposes of
the exchange offer, we will be deemed to have accepted properly tendered old
notes for exchange if and when we have given oral (confirmed in writing) or
written notice thereof to the exchange agent.

          In all cases, issuance of exchange notes for the old notes that are
accepted for exchange pursuant to the exchange offer will be made only after
timely receipt by the exchange agent of certificates for such old notes or a
timely book-entry confirmation of such old notes into the exchange agent's
account at DTC pursuant to the book-entry transfer procedures described below, a
properly completed and duly executed letter of transmittal and all other
required documents. If any tendered old notes are not accepted for any reason
set forth in the terms and conditions of the exchange offer or if certificates
representing old notes are submitted for a greater principal amount than the
holder desires to exchange, such unaccepted or non-exchanged old notes will be
returned without expense to the tendering holder thereof (or, in the case of old
notes tendered by book-entry transfer into the exchange agent's account at DTC
pursuant to the book-entry transfer procedures described below, such
non-exchanged old notes will be credited to an account maintained with DTC) as
promptly as practicable after the expiration or termination of the exchange
offer.

BOOK-ENTRY TRANSFER

          Promptly after the date of this prospectus, the exchange agent will
make a request to establish an account with respect to the old notes at DTC for
purposes of the exchange offer. Any financial institution that is a participant
in DTC's systems may make book-entry delivery of old notes by causing DTC to
transfer such old notes into the exchange agent's account in accordance with
DTC's Automated Tender Offer Program ("ATOP"), procedures for transfer. However,
the exchange for the old notes so tendered will only be made after timely
confirmation of such book-entry transfer of old notes into the exchange agent's
account, and timely receipt by the exchange agent of an agent's message and any
other documents required by the letter of transmittal. The term "agent's
message" means a message, transmitted by DTC and received by the exchange agent
and forming a part of a book-entry confirmation, which states that DTC has
received an express acknowledgment from a participant tendering old notes that
are the subject of such book-entry confirmation, that such participant has
received and agrees to be bound by the terms of the letter of transmittal, and
that we may enforce such agreement against such participant.

          Although delivery of old notes may be effected through book-entry
transfer into the exchange agent's account at DTC, the letter of transmittal (or
facsimile thereof), properly completed and duly executed, with any required
signature guarantees and any other required documents, must in any case be
delivered to and received by the exchange agent at its address set forth under
"--Exchange Agent" on or prior to the expiration date, or the guaranteed
delivery procedure set forth below must be complied with.

          Delivery of documents to DTC in accordance with its procedures does
not constitute delivery to the exchange agent.

GUARANTEED DELIVERY PROCEDURES

          If a registered holder of the old notes desires to tender such old
notes and (1) the old notes are not immediately available, (2) time will not
permit such holder's old notes or other required documents to reach the exchange


                                       14



agent before the expiration date of the exchange offer, or (3) the procedure for
book-entry transfer cannot be completed on a timely basis, a tender may be
effected if:

          o    the tender is made through an eligible institution;

          o    prior to the expiration date of the exchange offer, the exchange
               agent receives from such eligible institution a properly
               completed and duly executed letter of transmittal (or a facsimile
               letter of transmittal) and notice of guaranteed delivery,
               substantially in the form provided by us (by telegram, telex,
               facsimile transmission, mail or hand delivery),

          o    setting forth the name and address of the holder of old notes and
               the amount of old notes tendered, stating that the tender is
               being made thereby and guaranteeing that within five New York
               Stock Exchange trading days after the date of execution of the
               notice of guaranteed delivery, the certificates of all physically
               tendered old notes, in proper form for transfer, or a book-entry
               confirmation, as the case may be, and any other documents
               required by the letter of transmittal will be deposited by the
               eligible institution with the exchange agent; and

          o    the certificates for all physically tendered old notes, in proper
               form for transfer, or a book-entry confirmation, as the case may
               be, and all other documents required by the letter of
               transmittal, are received by the exchange agent within five New
               York Stock Exchange trading days after the date of execution of
               the notice of guaranteed delivery.

WITHDRAWAL RIGHTS

          Tenders of old notes may be withdrawn at any time prior to the
expiration date.

          For a withdrawal to be effective, a written notice of withdrawal must
be received by the exchange agent at one of the addresses set forth below under
"Exchange Agent." Any such notice of withdrawal must specify:

          o    the name of the person having tendered the old notes to be
               withdrawn;

          o    the old notes to be withdrawn (including the principal amount of
               such old notes); and

          o    where certificates for old notes have been transmitted, the name
               in which such old notes are registered, if different from that of
               the withdrawing holder.

          If certificates for old notes have been delivered or otherwise
identified to the exchange agent, then, prior to the release of such
certificates, the withdrawing holder must also submit the serial numbers of the
particular certificates to be withdrawn and a signed notice of withdrawal with
signatures guaranteed by an eligible institution unless such holder is an
eligible institution. If old notes have been tendered pursuant to the procedure
for book-entry transfer described above, any notice of withdrawal must specify
the name and number of the account at DTC to be credited with the withdrawn old
notes and otherwise comply with the procedures of such facility. All questions
as to the validity, form and eligibility (including time of receipt) of such
notices will be determined by us in our sole discretion, and our determination
will be final and binding on all parties.

          Any old notes so withdrawn will be deemed not to have been validly
tendered for exchange for purposes of the exchange offer. Any old notes which
have been tendered for exchange but which are not exchanged for any reason will
be returned to its holder without cost to such holder (or, in the case of old
notes tendered by book-entry transfer into the exchange agent's account at DTC
pursuant to the book-entry transfer procedures described above, such old notes
will be credited to an account maintained with DTC for the old notes) as soon as
practicable after withdrawal, rejection of tender or termination of the exchange
offer. Properly withdrawn old notes may be re-entered by following one of the
procedures described under "Procedures for Tendering Old Notes" above at any
time on or prior to the expiration date.


                                       15



CERTAIN CONDITIONS TO THE EXCHANGE OFFER

          Notwithstanding any other provisions of the exchange offer, we are not
required to accept for exchange, or to issue exchange notes in exchange for old
notes, and we may terminate or amend the exchange offer, if at any time before
the acceptance of such old notes for exchange or the exchange of the exchange
notes for such old notes, such acceptance or issuance would violate applicable
law or any interpretation of the SEC's staff.

          The condition in the paragraph immediately above is for our sole
benefit and may be asserted by us regardless of the circumstances giving rise to
such condition. Our failure at any time to exercise the foregoing rights is not
to be deemed a waiver of any such right and each such right shall be deemed an
ongoing right which may be asserted at any time and from time to time.

          In addition, we will not accept for exchange any old notes tendered,
and no exchange notes will be issued in exchange for any such old notes, if at
such time any stop order is threatened or in effect with respect to the
registration statement of which this prospectus constitutes a part or the
qualification of the indenture under the Trust Indenture Act.

EXCHANGE AGENT

          Bank One Trust Company, National Association has been appointed as the
exchange agent for the exchange offer. All executed letters of transmittal
should be directed to the exchange agent at one of the addresses set forth
below. Questions and requests for assistance, requests for additional copies of
this prospectus or of the letter of transmittal and requests for notices of
guaranteed delivery should be directed to the exchange agent, addressed as

          Delivery to an address other than as set forth above or transmission
of instructions via facsimile other than as set forth above does not constitute
a valid delivery.

FEES AND EXPENSES

          The principal solicitation is being made by mail; however, additional
solicitation may be made by telegraph, telecopy, telephone or in person by our
officers, regular employees, affiliates and agents. We will not pay any
additional compensation to any such officers and employees who engage in
soliciting tenders. We will not make any payment to brokers, dealers, or others
soliciting acceptances of the exchange offer. However, we will pay the exchange
agent reasonable and customary fees for its services and will reimburse it for
its reasonable out-of-pocket expenses in connection therewith.


                                       16



          The estimated cash expenses to be incurred in connection with the
exchange offer will be paid by us and are estimated in the aggregate to be
$200,000.

ACCOUNTING TREATMENT

          The exchange notes will be recorded at the same carrying value as the
old notes. Accordingly, DPL will not recognize any gain or loss for accounting
purposes. DPL intends to amortize the expenses of the exchange offer and
issuance of the old notes over the term of the exchange notes.

RESALE OF THE EXCHANGE NOTES

          Based on an interpretation by the SEC's staff contained in several
no-action letters issued to third parties, we believe that the exchange notes
issued pursuant to the exchange offer may be offered for resale, resold and
otherwise transferred after the exchange offer by any holder of exchange notes
(other than a holder which is our "affiliate" within the meaning of Rule 405
under the Securities Act) without compliance with the registration and
prospectus delivery provisions of the Securities Act, if such holder:

          o    acquires the exchange notes in the ordinary course of his or her
               business; and

          o    does not intend to participate, and has no arrangement with any
               person to participate, in a distribution of the exchange notes.

          Any holder of the old notes who tenders in the exchange offer with the
intention to participate, or for the purpose of participating, in a distribution
of the exchange notes may not rely on the position of the staff of the
Commission enunciated in the "Exxon Capital Holdings Corporation" or similar
no-action letters (the Exxon Capital Letters) but rather must comply with the
registration and prospectus delivery requirements of the Securities Act in
connection with any resale transaction. In addition, any such resale transaction
should be covered by an effective registration statement containing the selling
security holders information required by Item 507 of Regulation S-K of the
Securities Act. Each broker-dealer that receives exchange notes for its own
account in exchange for the old notes, where such old notes were acquired by
such broker-dealer as a result of market-making activities or other trading
activities, may be a statutory underwriter and must acknowledge that it will
deliver a prospectus meeting the requirements of the Securities Act in
connection with any resale of such exchange notes.

          By tendering in the exchange offer, each holder will represent to us
(which representation may be contained in the Letter of Transmittal) to the
effect that:

          o    it is not our affiliate;

          o    it is not engaged in, and does not intend to engage in, and has
               no arrangement or understanding with any person to participate
               in, a distribution of the exchange notes to be issued in the
               exchange offer; and

          o    it is acquiring the exchange notes in its ordinary course of
               business.

          Each holder will acknowledge and agree that any broker-dealer and any
such holder using the exchange Offer to participate in a distribution of the
exchange notes acquired in the exchange offer:

          o    could not under Commission policy as in effect on the date of the
               registration rights agreement rely on the position of the
               Commission enunciated in the exxon capital letters;

          o    must comply with the registration and prospectus delivery
               requirements of the Securities Act in connection with a secondary
               resale transaction and that such secondary resale transaction
               must be covered by an effective registration statement containing
               the selling security holder information required by Item 507 of
               Regulation S-K if the resales are of exchange notes obtained by
               such Holder in exchange for old notes acquired by such Holder
               directly from us or our affiliate.


                                       17



                          DESCRIPTION OF EXCHANGE NOTES

GENERAL

          The old notes were, and the exchange notes will be, issued pursuant to
an indenture dated as of March 1, 2000, between us and Bank One Trust Company,
National Association and an officer's certificate establishing the old notes and
the exchange notes.

          The following description of the terms of the exchange notes does not
purport to be complete and is qualified in its entirety by reference to (a) the
indenture and (b) the officer's certificate. Whenever particular provisions or
defined terms in the indenture and officer's certificate are referred to under
this "Description of the Exchange Notes," such provisions or defined terms are
incorporated in this prospectus by reference.

          The indenture provides for our issuance of debt securities (including
the exchange notes), notes or other unsecured evidences of indebtedness in an
unlimited amount from time to time. The exchange notes will be our unsecured
obligations which, so long as they are unsecured, will rank equally in right of
payment of principal and interest with all of our other existing and future
senior unsecured obligations. The indenture provides that we may not grant a
lien on the capital shares of Dayton Power and Light to secure our debt
obligations without similarly securing the exchange notes, with certain
exceptions. However, the indenture does not limit the aggregate amount of
indebtedness we or our subsidiaries may issue. We are a holding company that
derives substantially all of our income from our operating subsidiaries. The
exchange notes therefore are effectively subordinated to debt and preferred
shares at the subsidiary level. Our financial statements included in the
incorporated documents show the aggregate amount of subsidiary debt and
preferred shares and our other debt as of the date of those statements.

          Purchases of notes or beneficial interests therein may be made in
minimum denominations of $1,000 and in integral multiples of $1,000.

PRINCIPAL AMOUNT, INTEREST AND MATURITY

          We will issue the exchange notes as a series of debt securities under
the indenture. The officer's certificate with respect to the exchange notes
limits the aggregate principal amount of the exchange notes to $425,000,000. The
exchange notes will mature on March 1, 2007. The exchange notes will bear
interest from the later of the date of issuance of the old notes or the date of
the last interest payment on the old notes, at the rate of 8 1/4% per annum,
payable semi-annually in arrears on March 1 and September 1 in each year,
commencing September 1, 2000. Interest will be paid to the persons in whose
names exchange notes are registered at the close of business on February 15 or
August 15 next preceding each semi-annual interest payment date. The amount of
interest payable for any period is computed on the basis of a 360-day year of
twelve 30-day months and for any period shorter than a full month, on the basis
of the actual number of days elapsed in such period. In the event that any date
on which interest is payable on the exchange notes is not a business day, the
payment of the interest payable on such date will be made on the next succeeding
day which is a business day (and without any interest or other payment in
respect of any such delay), with the same force and effect as if made on the
date the payment was originally payable.

          Principal and interest payments on the exchange notes, other than
certificated notes, will be made by DPL to Cede & Co. (as nominee of DTC) so
long as Cede & Co. is the registered owner. Disbursement of such payments to the
DTC participants is the responsibility of DTC, and disbursement of such payments
to the beneficial owners of the exchange notes is the responsibility of DTC
direct and indirect participants, all as described below under "Book-Entry,
Delivery and Form."

REDEMPTION

          The exchange notes may be redeemed prior to their maturity at any time
at our option, in whole or from time to time in part, at a redemption price
equal to the sum of:

          o    the principal amount of the exchange notes (or portion thereof)
               being redeemed plus accrued interest thereon to the redemption
               date; and


                                       18



          o    the make-whole amount (as defined below), if any, with respect to
               the exchange notes (or portion thereof) being redeemed.

As used in this prospectus:

          "Make-whole amount" means the excess, if any, of

          o    the sum, as determined by a quotation agent (as described below),
               of the present values of the principal amount of such notes,
               together with scheduled payments of interest (exclusive of
               interest to the date of redemption) from the redemption date to
               the stated maturity of the notes, in each case discounted to the
               redemption date on a semi-annual basis (assuming a 360-day year
               consisting of twelve 30-day months) at the adjusted treasury rate
               (as described below) over

          o    100% of the principal amount of the notes to be redeemed.

          "Adjusted treasury rate" means, with respect to any redemption date,
the rate per annum equal to the semi-annual equivalent yield to maturity of the
comparable treasury issue (as described below), calculated using a price for the
comparable treasury issue (expressed as a percentage of its principal amount)
equal to the comparable treasury price (as defined herein) for such redemption
date, calculated on the third business day preceding the redemption date, plus
in each case .35% (35 basis points).

          "Comparable treasury issue" means the United States Treasury security
selected by the quotation agent (as described below) as having a maturity
comparable to the remaining term from the redemption date to the stated maturity
of the notes that would be utilized, at the time of selection and in accordance
with customary financial practice, in pricing new issues of corporate debt
securities of comparable maturity to the remaining term of the senior notes.

          "Quotation agent" means the reference treasury broker/dealer that we
select.

          "Reference treasury broker/dealer" means a primary U.S. Government
securities broker/dealer selected by DPL.

         "Comparable treasury price" means, with respect to any redemption date,

          o    the average of the bid and asked prices for the comparable
               treasury issue (expressed in each case as a percentage of its
               principal amount) on the third business day preceding the
               redemption date, as set forth in the daily statistical release
               (or any successor release) published by the Federal Reserve Bank
               of New York and designated "Composite 3:30 p.m. Quotations for
               U.S. Government Securities" or

          o    if the release (or any successor release) is not published or
               does not contain such prices on that business day, the average of
               three (or such lesser number as is obtained by the trustee)
               reference treasury broker/dealer quotations for such redemption
               date.

          "Reference treasury broker/dealer quotations" means, with respect to
each reference treasury broker/dealer and any redemption date, the average, as
determined by the trustee, of the bid and asked prices for the comparable
treasury issue (expressed in each case as a percentage of its principal amount)
quoted in writing to the trustee by the reference treasury broker/dealer at 5:00
p.m., New York City time, on the third business day preceding the redemption
date.

          Notice of any redemption will be mailed at least 30 days but no more
than 60 days before the redemption date to each holder of exchange notes to be
redeemed. If, at the time notice of redemption is given, the redemption moneys
are not held by the trustee, the redemption may be made subject to their receipt
on or before the date fixed for redemption and such notice shall be of no effect
unless such moneys are so received. Upon payment of the redemption price, on and


                                       19



after the redemption date interest will cease to accrue on the exchange notes or
portions thereof called for redemption. The exchange notes are not subject to
any sinking fund.

PAYMENT AND PAYING AGENTS

          Interest on each exchange note on each interest payment date will be
paid to the person in whose name such exchange note is registered as of the
close of business on the regular record date relating to such interest payment
date. However, interest payable at maturity (whether at stated maturity, upon
redemption or otherwise) will be paid to the person to whom principal is paid.
If there has been a default in the payment of interest on any exchange note, the
defaulted interest may be payable to the person in whose name such note is
registered as of the close of business on a date selected by the trustee which
is not more than 15 days and not less than 10 days prior to the date we propose
for payment of such defaulted interest or in any other lawful manner not
inconsistent with the requirements of any securities exchange on which such
exchange note may be listed, if the trustee deems such manner of payment
practicable.

          The principal of and premium, if any, and interest on, the exchange
notes at maturity will be payable upon presentation of the exchange notes at the
designated corporate trust operations office of Bank One Trust Company, National
Association in the City of New York, as our paying agent. We may change the
place of payment on the exchange notes, may appoint one or more additional
paying agents (including us) and may remove any paying agent, all at our
discretion.

REGISTRATION AND TRANSFER

          The transfer of exchange notes may be registered, and the exchange
notes may be exchanged for other exchange notes, of authorized denominations and
of like tenor and aggregate principal amount, at the corporate trust office of
Bank One Trust Company, National Association in the city of Chicago, as security
registrar for the exchange notes. We may change the place for registration of
transfer and exchange of the exchange notes and may designate one or more
additional places for such registration and exchange, all at our discretion. No
service charge will be made for any transfer or exchange of the exchange notes,
but we may require payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in connection with any registration of
transfer or exchange of the exchange notes. We will not be required to execute
or to provide for the registration of transfer of, or the exchange of, any
exchange notes during a period of 15 days prior to giving any notice of
redemption or any exchange notes selected for redemption in whole or in part,
except the unredeemed portion of any notes being redeemed in part.

DEFEASANCE

          The principal amount of any series of debt securities issued under the
indenture will be deemed to have been paid for purposes of the indenture and our
entire indebtedness in respect thereof will be deemed to have been satisfied and
discharged upon fulfillment of certain conditions if there shall have been
irrevocably deposited with the trustee or any paying agent, in trust:

          o    money in an amount which will be sufficient; or

          o    in the case of a deposit made prior to the maturity of the debt
               securities, eligible obligations (as described below), the
               principal of and the interest on which when due, without any
               regard to reinvestment thereof, will provide moneys which,
               together with the money, if any, deposited with or held by the
               trustee, will be sufficient; or

          o    a combination of the foregoing which will be sufficient, to pay
               when due the principal of and premium, if any, and interest, if
               any, due and to become due on the debt securities of such series
               that are outstanding. For this purpose, "eligible obligations"
               include direct obligations of, or obligations unconditionally
               guaranteed by, the United States entitled to the benefit of the
               full faith and credit thereof and certificates, depositary
               receipts or other instruments which evidence a direct ownership
               interest in such obligations or in any specific interest or
               principal payments due in respect thereof and which do not


                                       20



               contain provisions permitting the redemption or other prepayment
               thereof at the option of the issuer thereof.

LIMITATION ON LIENS

          The indenture provides that, except as otherwise specified with
respect to a particular series of debt securities, so long as any debt
securities of any series are outstanding, we will not pledge, mortgage,
hypothecate or grant a security interest in, or permit any mortgage, pledge,
security interest or other lien upon, any capital shares of Dayton Power and
Light that we now or hereafter own to secure any indebtedness (as described
below), without making effective provision so that the outstanding debt
securities shall (so long as the other indebtedness shall be so secured) be
equally and ratably secured with any and all other indebtedness and any other
indebtedness similarly entitled to be equally and ratably secured. This
restriction does not apply to, or prevent the creation or existence of,

          o    any mortgage, pledge, security interest, lien or encumbrance upon
               any such capital shares created at the time of our acquisition of
               those capital shares or within one year after that time to secure
               all or a portion of the purchase price for those capital shares;

          o    any mortgage, pledge, security interest, lien or encumbrance by
               us upon any of those capital shares existing at the time of our
               acquisition of those shares (whether or not we assume the
               obligations secured),or

          o    any extension, renewal or refunding of any mortgage, pledge,
               security interest, lien or encumbrance described in either of the
               previous two bullet points on capital shares of Dayton Power and
               Light (or substantially the same capital shares) or any portion
               thereof.

          o    any judgment, levy, execution, attachment or other similar lien
               arising in connection with court proceedings, provided that
               either

               (a)  the execution or enforcement of each such lien is
                    effectively stayed within 30 days after entry of the
                    corresponding judgment (or the corresponding judgment has
                    been discharged within such 30 day period) and the claims
                    secured thereby are being contested in good faith by
                    appropriate proceedings timely commenced and diligently
                    prosecuted;

               (b)  the payment of each lien is covered in full by insurance and
                    the insurance company has not denied or contested coverage
                    on it; or

               (c)  so long as each lien is adequately bonded, any appropriate
                    legal proceedings that may have been duly initiated for the
                    review of the corresponding judgment, decree or order shall
                    not have been fully terminated or the period within which
                    such proceedings may be initiated shall not have expired.

          For purposes of the restriction described in the preceding bullet
points:

          "Indebtedness" means

          o    all indebtedness, whether or not represented by bonds,
               debentures, notes or other securities, created or assumed by us
               for the repayment of money borrowed;

          o    all indebtedness for money borrowed secured by a lien upon
               property we own and upon which indebtedness for money we borrowed
               customarily pays interest, even though we have not assumed or
               become liable for the payment of such indebtedness for money
               borrowed; and

          o    all indebtedness of others for money borrowed which we guaranteed
               as to payment of principal or in effect guaranteed through a
               contingent agreement to purchase that indebtedness, but excluding


                                       21



               from this definition any of our other contingent obligations in
               respect of indebtedness for money borrowed or other obligations
               incurred by others.

          Notwithstanding the foregoing, except as otherwise specified in the
officer's certificate with respect to a particular series of debt securities, we
may, without securing the debt securities, pledge, mortgage, hypothecate or
grant a security interest in, or permit any mortgage, pledge, security interest
or other lien (in addition to liens expressly permitted as described in the
second preceding paragraph) upon, capital shares of Dayton Power and Light that
we now or hereafter own to secure any indebtedness (which would otherwise be
subject to the foregoing restriction) in an aggregate amount which, together
with all other such indebtedness, does not exceed 10% of consolidated
capitalization. For this purpose, "consolidated capitalization" means the sum
obtained by adding

          o    consolidated shareholders' equity;

          o    consolidated indebtedness for money borrowed (exclusive of any
               consolidated indebtedness which is due and payable within one
               year of the date such sum is determined); and, without
               duplication,

          o    any preference or preferred shares that we or any of our
               consolidated subsidiaries issue which is subject to mandatory
               redemption or sinking fund provisions.

          The term "consolidated shareholders' equity" (as used above) means the
total assets (as described below) of us and our consolidated subsidiaries less
all liabilities of us and our consolidated subsidiaries. As used in the
foregoing definition, "liabilities" means all obligations which would, in
accordance with generally accepted accounting principles in the United States,
be classified on a balance sheet as liabilities, including without limitation,

          o    indebtedness secured by property of our's or any of our
               consolidated subsidiaries whether or not we or the consolidated
               subsidiary is liable for the payment thereof unless, in the case
               that we or the consolidated subsidiary is not so liable, such
               property has not been included among our assets or the
               consolidated subsidiary on such balance sheet,

          o    deferred liabilities and

          o    indebtedness of us or any of our consolidated subsidiaries that
               is expressly subordinated in right and priority of payment to
               other liabilities of us or the consolidated subsidiary.

          As used in this definition, "liabilities" includes preference or
preferred stock of us or any consolidated subsidiary only to the extent of any
preference or preferred stock that is subject to mandatory redemption or sinking
fund provisions.

          The term "consolidated subsidiary" (as used above) means at any date
any subsidiary whose financial statements would be consolidated with our
consolidated financial statements as of that date under generally accepted
accounting principles. The "assets" of any person means the whole or any part of
its business, property, assets, cash and receivables. The term "consolidated
indebtedness" means total indebtedness as shown on the consolidated balance
sheet of us and our consolidated subsidiaries.

          As of December 31, 1999, our consolidated capitalization was
approximately $2.8 billion.

CONSOLIDATION, MERGER, AND SALE OF ASSETS

          Under the terms of the indenture, we may not consolidate with or merge
into any other entity or convey, transfer or lease our properties and assets
substantially as an entirety to any other entity, unless

          o    the corporation formed by such consolidation or into which we are
               merged or the entity which acquires by conveyance or transfer, or
               which leases, our property and assets substantially as an
               entirety will be an entity organized and validly existing under
               the laws of any domestic jurisdiction and such entity expressly
               assumes our obligations on all debt securities and under the
               indenture;


                                       22



          o    immediately after giving effect to the transaction, no event of
               default, and no event which, after notice or lapse of time or
               both, would become an event of default, will have occurred and be
               continuing; and

          o    We deliver to the trustee an officer's certificate and an opinion
               of counsel as provided in the indenture.

EVENTS OF DEFAULT

          Each of the following will constitute an event of default under the
indenture with respect to the debt securities of any series:

          o    failure to pay any interest on the debt securities of such series
               within 30 days after the same becomes due and payable;

          o    failure to pay principal or premium, if any, on the debt
               securities of such series when due and payable;

          o    failure to pay any sinking fund installment when and as due by
               the terms of the debt securities of such series;

          o    failure to perform, or breach of, any of our other covenants or
               warranties in the indenture (other than a covenant or warranty in
               the indenture solely for the benefit of one or more series of
               debt securities other than such series) for 60 days after written
               notice to us by the trustee, or to us and the trustee by the
               holders of at least 33% in principal amount of the debt
               securities of such series outstanding under the indenture and;

          o    certain events in bankruptcy, insolvency or reorganization of
               DPL.

          Additional events of default for a series of debt securities may be
specified at the time such series is created. An event of default with respect
to the debt securities of a particular series may not necessarily constitute an
event of default with respect to debt securities of any other series issued
under the indenture.

REMEDIES

          If an event of default due to our default in payment of principal of
or interest on any series of debt securities or due to our default in the
performance or breach of any other covenant or warranty applicable to the debt
securities of that series but not applicable to all series occurs and is
continuing, then either the trustee or the holders of at least 33% in principal
amount of the outstanding debt securities of that series may declare the
principal of all of the debt securities of such series and interest accrued
thereon to be due and payable immediately. If an event of default due to the
default in the performance of any other covenants or agreements in the indenture
applicable to all outstanding debt securities, either the trustee or the holders
of not less than 33% in principal amount of all outstanding debt securities,
considered as one class, and not the holders of the debt securities of any one
of such series, may make such declaration of acceleration. In certain events of
bankruptcy, insolvency, reorganization, assignment or receivership of us, the
principal and interest on all debt securities shall automatically become due and
payable.

          At any time after the declaration of acceleration with respect to the
debt securities of any series has been made and before a judgment or decree for
payment of the money due has been obtained, the event or events of default
giving rise to such declaration of acceleration will, without further act, be
deemed to have been waived, and such declaration and its consequences will,
without further act, be deemed to have been rescinded and annulled, if:

          o    we have paid or deposited with the trustee a sum sufficient to
               pay:

               (1) all overdue interest on all debt securities of the series;


                                       23



               (2) the principal of and premium, if any, on any debt securities
of the series which have become due otherwise than by the declaration of
acceleration and interest thereon at the rate or rates prescribed therefor in
the debt securities;

               (3) interest upon overdue interest at the rate or rates
prescribed therefor in the debt securities, to the extent that payment of the
interest is lawful;

               (4) and all amounts due to the trustee under the indenture; and

          o    any other event or events of default with respect to debt
               securities of that series, other than the nonpayment of the
               principal of the debt securities of that series which has become
               due solely by such declaration of acceleration, have been cured
               or waived as provided in the indenture.

          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
the holders will have offered to the trustee reasonable indemnity. If an event
of default has occurred and is continuing in respect of a series of debt
securities, subject to the provisions for the indemnification of the trustee,
the holders of a majority in principal amount of the outstanding debt securities
of the 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 the series; provided, however, that if an event of default occurs and is
continuing with respect to more than one series of debt securities, the holders
of a majority in aggregate principal amount of the outstanding debt securities
of all that series, considered as one class, will have the right to make the
direction, and not the holders of the debt securities of any one of such series;
and provided, further, that the direction will not be in conflict with any rule
of law or with the indenture.

          No holder of debt securities 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:

          o    the holder has previously given to the trustee written notice of
               a continuing event of default with respect to the debt securities
               of that series;

          o    the holders of a majority in aggregate principal amount of the
               outstanding debt securities of all series in respect of which an
               event of default shall have occurred and be continuing,
               considered as one class, have made written request to the
               trustee, and the holder or holders have offered reasonable
               indemnity to the trustee to institute the proceeding in respect
               of the event of default in its own name as trustee; and

          o    the trustee has failed to institute any proceeding, and has not
               received from the holders of a majority in aggregate principal
               amount of the outstanding debt securities of such series a
               direction inconsistent with such request, within 60 days after
               such notice, request and offer.

          These 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
an appropriate officer as to that officer's knowledge of our compliance with all
conditions and covenants under the indenture, the compliance to be determined
without regard to any period of grace or requirement of notice under the
indenture.

MODIFICATION AND WAIVER

          Without the consent of any holder of debt securities, we and the
trustee may enter into one or more supplemental indentures for any of the
following purposes:

          o    to evidence the assumption by any of our permitted successors of
               our covenants in the indenture and in the debt securities; or


                                       24



          o    to add to our covenants or other provisions for the benefit of
               all holders or for the benefit of the holders of, or to remain in
               effect only so long as there will be outstanding debt securities
               of one or more specified series, or one or more specified
               tranches thereof, or to surrender any right or power conferred
               upon us by the indenture; or

          o    to add any additional events of default with respect to
               outstanding debt securities; or

          o    to change or eliminate any provision of the indenture or to add
               any new provision to the indenture, provided that if such change,
               elimination or addition will adversely affect the interests of
               the holders of debt securities of any series or tranche in any
               material respect, such change, elimination or addition will
               become effective with respect to such series or tranche only:

               (1) when the consent of the holders of debt securities of such
series or tranche has been obtained in accordance with the indenture, or

               (2) when no debt securities of such series or tranche remain
outstanding under the indenture; or

          o    to provide collateral security for all but not part of the debt
               securities; or

          o    to establish the form or terms of debt securities of any other
               series or tranche as permitted by the indenture; or

          o    to provide for the authentication and delivery of bearer
               securities and coupons appertaining thereto representing
               interest, if any, thereon and for the procedures for the
               registration, exchange and replacement thereof and for the giving
               of notice to, and the solicitation of the vote or consent of, the
               holders thereof, and for any and all other matters incidental
               thereto; or

          o    to evidence and provide for the acceptance of appointment of a
               successor trustee with respect to the debt securities of one or
               more series and to add to or change any of the provisions of the
               indenture as will be necessary to provide for or to facilitate
               the administration of the trusts under the indenture by more than
               one trustee; or

          o    to provide for the procedures required to permit the utilization
               of a noncertificated system of registration for the debt
               securities of all or any series or tranche; or

          o    to change any place where the principal of and premium, if any,
               and interest, if any, on all or any series or tranche of debt
               securities will be payable, all or any series or tranche of debt
               securities may be surrendered for registration of transfer or
               exchange and notices and demands to or upon us in respect of debt
               securities and the indenture may be served;

          o    to cure any ambiguity or inconsistency or to add or change any
               other provisions with respect to matters and questions arising
               under the indenture, provided such changes or additions will not
               adversely affect the interests of the holders of debt securities
               of any series or tranche in any material respect; or

          o    to maintain the qualification of the indenture under the Trust
               Indenture Act.

          The holders of a majority in aggregate principal amount of the debt
securities of all series then outstanding 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 with respect to that series, except a default in the
payment of principal, premium, or interest and certain covenants and provisions
of the indenture that cannot be modified or be amended without the consent of
the holder of each outstanding debt security of the series affected.

          Except as provided above, the consent of the holders of a majority in
aggregate principal amount of the debt securities of all series then
outstanding, considered as one class, is required for the purpose of adding any


                                       25



provisions to, or changing in any manner, or eliminating any of the provisions
of, the indenture or modifying in any manner the rights of the holders of such
debt securities under the indenture pursuant to one or more supplemental
indentures; provided, however, that if less than all of the series of debt
securities outstanding are directly affected by a proposed supplemental
indenture, then the consent only of the holders of a majority in aggregate
principal amount of outstanding debt securities of all series so directly
affected, considered as one class, will be required; and provided, further, that
if the debt securities of any series shall have been issued in more than one
tranche and if the proposed supplemental indenture will directly affect the
rights of the holders of debt securities of one or more, but less than all, of
those tranches, then the consent only of the holders of a majority in aggregate
principal amount of the outstanding debt securities of all tranches so directly
affected, considered as one class, will be required; and provided further, that
no such amendment or modification may:

          o    change the stated maturity of the principal of, or any
               installment of principal of or interest on, any debt security, or
               reduce the principal amount thereof or the rate of interest
               thereon (or the amount of any installment of interest thereon) or
               change the method of calculating such rate or reduce any premium
               payable upon the redemption thereof, or change the coin or
               currency (or other property) in which any debt security or any
               premium or the interest thereon is payable, or impair the right
               to institute suit for the enforcement of any such payment on or
               after the stated maturity of any debt security (or, in the case
               of redemption, on or after the redemption date) without, in any
               such case, the consent of the holder of such debt security;

          o    reduce the percentage in principal amount of the outstanding debt
               securities of any series, or any tranche thereof, the consent of
               the holders of which is required for any supplemental indenture,
               or the consent of the holders of which is required for any waiver
               of compliance with any provision of the indenture or any default
               thereunder and its consequences, or reduce the requirements for
               quorum or voting, without, in any such case, the consent of the
               holder of each outstanding debt security of that series or
               tranche, or

          o    modify certain of the provisions of the indenture relating to
               supplemental indentures, waivers of certain covenants and waivers
               of past defaults with respect to the debt securities of any
               series or tranche, without the consent of the holder of each
               outstanding debt security affected thereby. A supplemental
               indenture which changes or eliminates any covenant or other
               provision of the indenture which has expressly been included
               solely for the benefit of one or more particular series of debt
               securities or one or more tranches thereof, or modifies the
               rights of the holders of debt securities of that series or
               tranche with respect to such covenant or other provision, will be
               deemed not to affect the rights under the indenture of the
               holders of the debt securities of any other series or tranche.

          The indenture provides that in determining whether the holders of the
requisite principal amount of the outstanding debt securities have given any
request, demand, authorization, direction, notice, consent or waiver under the
indenture, or whether a quorum is present at the meeting of the holders of debt
securities, debt securities owned by us or any other obligor upon the debt
securities or any affiliate of our's or of such other obligor (unless we, such
affiliate or such obligor own all debt securities outstanding under the
indenture, determined without regard to this provision) will be disregarded and
deemed not to be outstanding.

          If we solicit from holders any request, demand, authorization,
direction, notice, consent, election, waiver or other act, we may, at our
option, fix in advance a record date for the determination of holders entitled
to give that request, demand, authorization, direction, notice, consent, waiver
or other act, but we will have no obligation to do so. If a record date is
fixed, the request, demand, authorization, direction, notice, consent, waiver or
other act may be given before or after the record date, but only the holders of
record at the close of business on that record date will be deemed to be holders
for the purposes of determining whether holders of the requisite proportion of
the outstanding debt securities have authorized or agreed or consented to the
request, demand, authorization, direction, notice, consent, waiver or other act,
and for that purpose the outstanding debt securities will be computed as of the
record date. Any request, demand, authorization, direction, notice, consent,
election, waiver or other act of a holder will bind every future holder of the
same debt security and the holder of every debt security issued upon the
registration of transfer thereof or in exchange therefor or in lieu thereof in
respect of anything done, omitted or suffered to be done by the trustee or us in


                                       26



reliance thereon, whether or not notation of such action is made upon such debt
security.

RESIGNATION OF TRUSTEE

          The trustee may resign at any time by giving written notice thereof to
us or may be removed at any time by act of the holders of a majority in
principal amount of all series of debt securities then outstanding delivered to
the trustee and us. No resignation or removal of the trustee and no appointment
of a successor trustee will become effective until the acceptance of appointment
by a successor trustee in accordance with the requirements of the indenture. So
long as no event of default or event which, after notice or lapse of time, or
both, would become an event of default has occurred and is continuing and except
with respect to a trustee appointed by act of the holders, if we have delivered
to the trustee a resolution of its board of directors appointing a successor
trustee and such successor has accepted such appointment in accordance with the
terms of the indenture, the trustee will be deemed to have resigned and the
successor will be deemed to have been appointed as trustee in accordance with
the indenture.

NOTICES

          Notices to holders of debt securities will be given by first class
mail to the address of each holder as it may appear in the security register.

TITLE

          We, the trustee, and any of our agents or the trustee, may treat the
person in whose name debt securities are registered as the absolute owner
thereof (whether or not the debt securities may be overdue) for the purpose of
making payments and for all other purposes irrespective of notice to the
contrary.

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.

REGARDING THE TRUSTEE

          The trustee under the indenture is Bank One Trust Company, National
Association. We and Dayton Power and Light also maintain various banking and
trust relationships with Bank One Trust Company, National Association.

BOOK-ENTRY, DELIVERY AND FORM

     GENERAL

          The exchange notes will be issued in the form of one or more fully
registered securities in global form. The global notes will be deposited with,
or on behalf of, The Depository Trust Company and registered in the name of The
Depositary Trust Company or its nominee.

          Upon issuance of the global notes, The Depositary Trust Company or its
nominee will credit, on its book-entry registration and transfer system, the
respective principal amount of the individual beneficial interests represented
by such global notes to the accounts of persons who have accounts with the
depository. Ownership of beneficial interests in the global notes will be shown
on, and the transfer of that ownership will be effected only through, records
maintained by The Depositary Trust Company or its nominee (with respect to the
participants' interests) for the global notes, or by participants or persons
that hold interests through participants (with respect to beneficial interests
of persons other than participants). The laws of some jurisdictions may require
that certain purchasers of securities take physical delivery of the securities
in definitive form. These limits and laws may impair the ability to transfer or
pledge beneficial interests in the global notes.


                                       27



          So long as The Depositary Trust Company, or its nominee, is the
registered holder of any global notes, The Depositary Trust Company or such
nominee, as the case may be, will be considered the sole legal owner of the
global notes for all purposes under the indenture and the exchange notes. Except
as set forth below, owners of beneficial interests in global notes will not be
entitled to have their global notes registered in their names, will not receive
or be entitled to receive physical delivery in exchange therefor and will not be
considered to be the owners or holders of their global notes for any purpose
under the securities or the indenture. We understand that under existing
industry practice, in the event an owner of a beneficial interest in a global
note desires, to take any action that The Depositary Trust Company, as the
holder of the global note, is entitled to take, The Depositary Trust Company
would authorize the participants to take that action, and that the participants
would authorize beneficial owners owning through those participants to take that
action or would otherwise act upon the instructions of beneficial owners owning
through them.

          Any payment of principal or interest due on the exchange notes on any
interest payment date or at maturity will be made available by us to the trustee
by that date. As soon as practicable thereafter, the trustee will make those
payments to The Depositary Trust Company or its nominee, as its nominee, as the
case may be, as the registered owner of the global notes representing the
exchange notes in accordance with existing arrangements between the trustee and
The Depositary Trust Company.

          We expect that The Depositary Trust Company or its nominee, upon
receipt of any payment of principal or interest in respect of the global notes,
will credit immediately the accounts of the related participants with payments
in amounts proportionate to their respective beneficial interests in the
principal amount of the global notes as shown on the records of The Depositary
Trust Company. We also expect that payments by participants to owners of
beneficial interests in the global notes held through the participants will be
governed by standing 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.

          Neither us, nor the trustee, nor any payment agent for the global
notes will have any responsibility or liability for any aspect of the records
relating to or payments made on account of beneficial ownership interests in any
of the global notes or for maintaining, supervising or reviewing any records
relating to the beneficial ownership interests or for other aspects of the
relationship between The Depositary Trust Company and its participants or the
relationship between the participants and the owners of beneficial interests in
the global notes owning through the participants.

          Unless and until exchanged in whole or in part for securities in
definitive form in accordance with the terms of the securities, the global notes
may not be transferred except as a whole by the The Depositary Trust Company to
a nominee of The Depositary Trust Company or by a nominee of the The Depositary
Trust Company to The Depositary Trust Company or another nominee of The
Depositary Trust Company or by The Depositary Trust Company of any such nominee
to a successor of The Depositary Trust Company or a nominee of each successor.

          Although The Depositary Trust Company has agreed to the foregoing
procedures in order to facilitate transfers of interests in the global notes
among participants of The Depositary Trust Company, it is under no obligation to
perform or continue to perform those procedures, and those procedures may be
discontinued at any time. Neither the trustee nor us will have any
responsibility for the performance by The Depositary Trust Company or its
participants or indirect participants of their respective obligations under the
rules and procedures governing their operations. Us and the trustee may
conclusively rely on, and shall be protected in relying on, instructions from
The Depositary Trust Company for all purposes.

CERTIFICATED NOTES

          Securities that are originally issued to institutional "accredited
investors" who are not qualified institutional buyers will be sold in
certificated form.

          The global notes shall be exchangeable for corresponding certificated
securities registered in the name of persons other than The Depositary Trust
Company or its nominee only if:


                                       28



          o    The Depositary Trust Company (a) notifies us that it is unwilling
               or unable to continue as the depositary for any of the global
               notes or (b) at any time ceases to be a clearing agency
               registered under the exchange act,

          o    there shall have occurred and be continuing an event of default
               (as defined in the indenture) with respect to the applicable
               securities or

          o    We execute and deliver to the trustee an order that the global
               notes shall be so exchangeable.

Any certificated securities will be issued only in fully registered form and
shall be issued without coupons in minimum denominations of $1,000 and in
integral multiples of $1,000. Any certificated securities so issued will be
registered in the names and in the denominations as The Depositary Trust Company
shall request.

THE CLEARING SYSTEM

          The Depositary Trust Company has advised us as follows: The Depositary
Trust Company is a limited-purpose trust company organized under the laws of the
State of New York, a member of the Federal Reserve System, a "clearing
corporation" within the meaning of the New York Uniform Commercial Code, and "a
clearing agency" registered pursuant to the provisions of Section 17A of the
Exchange Act. The Depositary Trust Company was created to hold securities of
institutions that have accounts with The Depositary Trust Company
("participants") and to facilitate the clearance and settlement of securities
transactions among it participants in such securities through electronic
book-entry changes in accounts of participants, thereby eliminating the need for
physical movement of securities certificates. The Depositary Trust Company's
participants include securities brokers and dealers (which may include the
initial purchasers of the old notes), bank, trust companies, clearing
corporations and certain other organizations. Access to The Depositary Trust
Company's book-entry system is also available to others such as banks, brokers,
dealers and trust companies that clear through or maintain a custodial
relationship with a participant, whether directly or indirectly.

LACK OF PUBLIC MARKET

          The exchange notes are new issues of securities for which there is
currently no active trading market. If any exchange notes are traded after their
initial issuance, they may trade at a discount from their face value, depending
upon prevailing interest rates, the market for similar securities and other
factors, including general economic conditions and our financial condition,
performance and prospects.

            MATERIAL UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

          The following summary describes the material United States federal
income tax consequences of the acquisition, ownership and disposition of
exchange notes as of the date hereof and represents the opinion of Thelen Reid &
Priest LLP, counsel to DPL, insofar as it relates to matters of law or legal
conclusions. Except where noted, this summary deals only with exchange notes
held as capital assets within the meaning of section 1221 of the Internal
Revenue Code of 1986, as amended (the "Code") and does not deal with special
situations, such as those of dealers in securities or currencies, financial
institutions, tax-exempt entities, life insurance companies, individual
retirement and tax-deferred accounts, persons holding exchange notes as a part
of a hedging or conversion transaction or a straddle, or persons whose
functional currency is not the United States dollar. In addition, this
discussion does not address the tax consequences to persons who acquired old
notes other than pursuant to their initial issuance and distribution, and who
acquire exchange notes other than pursuant to the exchange offer. Furthermore,
the discussion below is based upon the provisions of the Code, existing and
proposed Treasury regulations promulgated thereunder, and applicable
administrative rulings and judicial decisions now in effect, all of which are
subject to change, possibly on a retroactive basis, so as to result in United
States federal income tax consequences different from those discussed below.

          A "United States person" is defined as (i) an individual citizen or
resident of the United States, (ii) a corporation, partnership or other entity
created or organized in or under the laws of the United States or any political
subdivision thereof, (iii) an estate, the income of which is subject to United
States federal income taxation regardless of its source, or (iv) a trust if (a)


                                       29



a court within the United States is able to exercise primary supervision over
the administration of the trust and (b) one or more United States persons have
the authority to control all substantial decisions of the trust. As used herein,
a "United States holder" means a beneficial owner of an exchange note that is a
United States person. As used herein, the term "non-United States holder" means
a beneficial owner of an exchange note that is not a United States holder.

          PROSPECTIVE HOLDERS OF EXCHANGE NOTES ARE ADVISED TO CONSULT WITH
THEIR TAX ADVISORS AS TO THE UNITED STATES FEDERAL INCOME TAX CONSEQUENCES OF
THE ACQUISITION, OWNERSHIP AND DISPOSITION OF EXCHANGE NOTES IN LIGHT OF THEIR
PARTICULAR CIRCUMSTANCES, AS WELL AS THE EFFECT OF ANY STATE, LOCAL OR OTHER TAX
LAWS.

EXCHANGE OF OLD NOTES FOR EXCHANGE NOTES

          An exchange of old notes for exchange notes pursuant to the exchange
offer should not constitute a taxable event for United States federal income tax
purposes because the exchange notes should not be considered materially
different in kind or extent from the old notes. Rather, beneficial interests in
the exchange notes should be treated as a continuation of beneficial interests
in old notes in the hands of a holder. As a result, holders who effect an
exchange pursuant to the exchange offer should not recognize any income, gain or
loss for United States federal income tax purposes with respect to the exchange.
In addition, a holder's tax basis in an exchange note will be the same as that
holder's basis in the old note exchanged therefor, and a holder's holding period
in an exchange note will include that holder's holding period in the old note
exchanged therefor.

UNITED STATES HOLDERS

          PAYMENTS OF INTEREST

          Interest on exchange notes will generally be taxable to a United
States holder as ordinary income at the time it is paid or accrued in accordance
with the United States holder's method of accounting for United States federal
income tax purposes.

          SALE, EXCHANGE OR REDEMPTION OF EXCHANGE NOTES

          Except as described above under "Exchange of Old Notes for Exchange
Notes," upon the sale, exchange or redemption of exchange notes, a United States
holder generally will recognize gain or loss equal to the difference between (i)
the amount realized upon the sale, exchange or redemption, and (ii) the United
States holder's adjusted tax basis in the exchange notes. A United States
holder's adjusted tax basis in the exchange notes will be the initial purchase
price it paid for the old notes exchanged therefor, net of accrued interest.
Such gain or loss will be capital gain or loss and will be long-term capital
gain or loss if, at the time of the sale, exchange or redemption, the United
States holder's holding period in the exchange notes (including the holding
period of the United States holder in the old notes) is greater than one year.
Under current law, the deductibility of capital losses is subject to
limitations. The net capital gains of individuals are generally taxed at lower
rates than ordinary income.

          INFORMATION REPORTING AND BACKUP WITHHOLDING

          Payments of interest on, or the proceeds from the sale, retirement, or
other disposition of exchange notes are subject to information reporting unless
the United States holder establishes an exemption.

          Payments of the interest on, or the proceeds from the sale,
retirement, or other disposition of exchange notes may be subject to a "backup
withholding" tax of 31% if the United States holder, among other things, (1)
fails to furnish his or her social security number or other taxpayer
identification number ("TIN") to the payor responsible for backup withholding
(for example, the United States holder's securities broker) on Internal Revenue
Service ("IRS") Form W-9 or a substantially similar form signed under penalties
of perjury, (2) furnishes the payor an incorrect TIN, (3) fails to provide the
payor with a certified statement, signed under penalties of perjury, that the
TIN provided to the payor is correct and that the United States holder is not
subject to backup withholding, or (4) fails to properly report interest and


                                       30



dividends on his tax return. Information reporting and backup withholding does
not apply to certain payments made to exempt recipients, such as corporations.

          Any amounts withheld under the backup withholding rules will be
allowed as a credit or refund against a United States holder's United States
federal income tax liability, if certain required information is provided to the
IRS.

NON-UNITED STATES HOLDERS


          PAYMENTS OF INTEREST

          Subject to the discussion below concerning backup withholding, no
withholding of United States federal income tax will be required with respect to
the payment by DPL or any paying agent of principal or interest on an exchange
note held by a non-United States holder, provided that the beneficial owner (1)
does not actually or constructively own 10% or more of the total combined voting
power of all classes of stock of DPL entitled to vote within the meaning of Code
section 871(h)(3) and the regulations thereunder; (2) is not a controlled
foreign corporation, within the meaning of Code section 957, which is related,
directly or indirectly, to DPL through stock ownership; and (3) satisfies the
requirement, described generally below, set forth in Code section 871(h) and
Code section 881(c) and the regulations thereunder.

          To satisfy the requirement referred to in clause (3) above, the
beneficial owner of an exchange note, or a financial institution holding an
exchange note on behalf of the beneficial owner, must provide, in accordance
with specified procedures, DPL or its paying agent with a statement to the
effect that the beneficial owner is not a United States person. These
requirements will be met if (1) the beneficial owner provides his name and
address, and certifies, under penalties of perjury, that he is not a United
States person, which certification may be made on an IRS Form W-8 (or successor
form); or (2) a financial institution holding the exchange note on behalf of the
beneficial owner certifies, under penalties of perjury, that such statement has
been received by it and furnishes a paying agent with a copy thereof.

          In the event that any of the above requirements are not satisfied, DPL
will nonetheless not withhold United States federal income tax on interest paid
to a non-United States holder if it receives either IRS Form 4224 (for taxable
years prior to January 1, 2001) or IRS Form W-8 ECI from that non-United States
holder, establishing that such income is effectively connected with the conduct
of a trade or business in the United States, unless DPL has knowledge to the
contrary. Interest paid to a non-United States holder that is effectively
connected with the conduct by the holder of a trade or business in the United
States is generally taxed at the graduated rates that are applicable to United
States persons. In the case of a non-United States holder that is a corporation,
such effectively connected income may also be subject to the United States
federal branch profits tax, which is generally imposed on a foreign corporation
on the deemed repatriation from the United States of effectively connected
earnings and profits, at a 30% rate, unless the rate is reduced or eliminated by
an applicable income tax treaty and the non-United States holder is a qualified
resident of the treaty country.

          SALE, EXCHANGE OR REDEMPTION OF THE NOTES

          A non-United States holder generally will not be subject to United
States federal income tax with respect to gain recognized on a sale, exchange or
redemption of an exchange note unless (1) the gain is effectively connected with
a trade or business of the non-United States holder in the United States; (2) in
the case of a non-United States holder who is an individual and holds the
exchange note as a capital asset, the holder is present in the United States for
183 or more days in the taxable year of the sale or other disposition and
certain other conditions are met; or (3) the non-United States holder is subject
to tax pursuant to certain provisions of the Code applicable to United States
expatriates. However, any amount attributable to accrued but unpaid interest on
the exchange note will be treated in the same manner as payments of interest
made to the non-United States holder, as described above.

          Gain derived by a non-United States holder from the sale or other
disposition of an exchange note that is effectively connected with the conduct
by the holder of a trade or business in the United States is generally taxed at
the graduated rates that are applicable to United States persons. In the case of
a non-United States holder that is a corporation, such effectively connected


                                       31



income may also be subject to the United States branch profits tax. If any
individual non-United States holder falls under clause (2) of the preceding
paragraph, the holder will be subject to a flat 30% tax on the gain derived from
the sale or other disposition, which may be offset by certain United States
source capital losses recognized within the same taxable year as the sale or
other disposition.

          INFORMATION REPORTING AND BACKUP WITHHOLDING

          Non-United States holders will not be subject to information reporting
or backup withholding on payments made by DPL or its paying agent if a statement
described in clause (3) of the first paragraph under "Non-United States Holders
- - Payments of Interest" has been received and the payor has no actual knowledge
that the beneficial owner is a United States person.

          In addition, backup withholding and information reporting will not
apply to payments of principal or interest on exchange notes paid or collected
by a foreign office of a custodian, nominee or other foreign agent on behalf of
a non-United States holder, or if a foreign office of a broker pays the proceeds
of the sale of exchange notes to a non-United States holder. If, however, the
nominee, custodian, agent or broker is, for United States federal income tax
purposes, a United States person, a controlled foreign corporation or a foreign
person that derives 50% or more of its gross income for certain periods from the
conduct of a United States trade or business, or (with respect to payments
after December 31, 2000) a foreign partnership with certain connections to the
United States, such payments will not be subject to backup withholding (unless
the payer has actual knowledge that the payee is a United States person) but
will be subject to information reporting unless (i) the custodian, nominee,
agent or broker has documentary evidence that the beneficial owner is not a
United States person and certain other conditions are met, or (ii) the
beneficial owner otherwise establishes an exemption.

          Payments of principal or interest on exchange notes paid to a
non-United States holder by a United States office of a custodian, nominee or
agent, or payment of the proceeds of a sale of exchange notes by the United
States office of a broker, will be subject to backup withholding and information
reporting unless (i) the non-United States holder provides the statement
described above that the holder is not a United States person and the payor does
not have actual knowledge to the contrary, or (ii) the beneficial owner
otherwise establishes an exemption.

          Any amounts withheld under the backup withholding rules will be
allowed as a credit or a refund against a non-United States holder's United
States federal income tax liability, if certain required information is provided
to the IRS.

                              PLAN OF DISTRIBUTION

          Each participating broker-dealer in connection with the exchange offer
must acknowledge that it will deliver a prospectus in connection with any resale
of exchange notes. This prospectus, as it may be amended or supplemented from
time to time, may be used by a participating broker-dealer in connection with
resales of exchange notes received in exchange for old notes where such old
notes were acquired as a result of market-making activities or other trading
activities. We have agreed that we will make this prospectus, as amended or
supplemented, available to any participating broker-dealer for use in connection
with any such resale and participating broker-dealers shall be authorized to
deliver this prospectus for a period ending upon the earlier of the expiration
of the 90th day after the exchange offer has been completed or such time as such
broker-dealers no longer own any registrable securities, which we define in the
registration rights agreement.

          We will not receive any proceeds from any sales of the exchange notes
by participating broker-dealers. Exchange notes received by participating
broker-dealers for their own account pursuant to the exchange offer may be sold
from time to time, in one or more transactions in the over-the-counter market,
in negotiated transactions, through the writing of options on the exchange notes
or a combination of such methods of resale, at market prices prevailing at the
time of resale, at prices related to the prevailing market prices or at
negotiated prices. Any resale may be made directly to purchasers or to or
through brokers or dealers who may receive compensation in the form of
commissions or concessions from any participating broker-dealer that resells the
exchange notes that were received by it for its own account pursuant to the
exchange offer. Any broker or dealer that participates in a distribution of the
exchange notes may be deemed to be an "underwriter" within the meaning of the


                                       32



Securities Act and any profit on any resale of exchange notes and any omissions
or concessions received by any persons may be deemed to be underwriting
compensation under the Securities Act. The letter of transmittal states that by
acknowledging that it will deliver and by delivering a prospectus, a
participating broker-dealer will not be deemed to admit that it is an
"underwriter" within the meaning of the Securities Act.

          We will promptly send additional copies of this prospectus and any
amendment or supplement to this prospectus to any participating broker-dealer
that requests such documents in the letter of transmittal. See "The Exchange
Offer."

                                  LEGAL MATTERS

          The validity of the exchange notes will be passed upon for us by
Stephen F. Koziar, Group Vice President and General Counsel of DPL and by Thelen
Reid & Priest LLP, New York, New York.

                                     PART II

                     INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

          Article VII of the Code of Regulations of the Company provides for
indemnification of directors, officers, employees or agents of the Company, or
individuals who server at the request of the Company in such capacities for
other entities, against any and all expenses, judgments, fines and settlements
incurred by them in connection with claims and/or litigation arising out of
their service. Article VII provides that indemnification shall be available to
the full extent permitted by law including, without limitation, Section
1701.13(E) of the Ohio Revised Code.

          Under Ohio law, the liabilities against which a director or officer
may be indemnified and factors employed to determine whether a director or
officer is entitled to indemnification in a particular instance depend on
whether the proceeding in which the claim for indemnification arises was brought
(a) other than by and in the right of the corporation ("Category A Proceedings")
or (b) by and in the right of the corporation ("Category B Proceedings").

          In Category A Proceedings, a corporation may indemnify each director
and officer against expenses, including attorneys' fees, judgements, fines,
penalties, and amounts paid in settlement actually and reasonably incurred by
him in connection with any threatened or actual proceeding in which he may be
involved by reason of his having acted in such capacity, if he acted in good
faith and in a manner he reasonably believed to be in or not opposed to the best
interests of the corporation, and with respect to any criminal action or
proceeding, he had no reasonable cause to believe that his conduct was unlawful.

          In Category B Proceedings, a corporation may indemnify each director
and officer against expenses, including attorneys' fees, actually and reasonably
incurred by him in connection with the defense or settlement of any such
proceeding if he acted in good faith and in a manner he reasonably believed to
be in or not opposed to the best interests of the corporation, except that no
indemnification is permitted with respect to (i) any matter as to which such
person has been adjudged to be liable for negligence or misconduct in the
performance of his duty to the corporation unless a court determines such person
is entitled to indemnification; or (ii) any matter in which the only liability
asserted against a director or officer relates to an unlawful loan, dividend,
distribution of assets or purchase or redemption of shares.

          Unless indemnification is ordered by a court, the determination as to
whether or not an individual has satisfied the applicable standards of conduct
(and therefore may be indemnified) is made by the corporation by a majority vote
of a quorum consisting of directors of the corporation who were not parties to
the action; or if such a quorum is not obtainable, or if a majority vote of a
quorum of disinterested directors so directs, by independent legal counsel in a
written opinion; or by the shareholders of the corporation; or by the court in
which such action was brought.

          Article VII does not limit in any way other indemnification rights to
which those seeking indemnification may be entitle. Ohio law requires
indemnification against expenses where a directors or officer is successful on
the merits or otherwise in defense of any action. Consistent with Ohio law,
Article VII provides that expenses incurred by a director or officer in
defending any action may be paid by the Company in advance of final disposition,
upon receipt of an undertaking to repay such amount unless it is ultimately
determined that he is entitled to indemnification pursuant to Article VII.

          The Company maintains insurance policies covering its officers and
directors against certain civil liabilities, including liabilities under the
Securities Act of 1933, as amended.

ITEM 21. EXHIBITS AND FINANCIAL STATEMENT SCHEDULES

          (a) Exhibits (see index to exhibits at E-1).

ITEM 22. UNDERTAKINGS

          (a) The undersigned registrant hereby undertakes:


                                      II-1



                    (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 ("Securities Act");

                              (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
                    thereof) which, individually or in the aggregate, represent
                    a fundamental change in the information set forth in the
                    registration statement; and

                              (iii) To include any material information with
                    respect to the plan of distribution not previously disclosed
                    in the registration statement or any material change to such
                    information in the registration statement.

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

                    (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.

                    (4) That, for purposes of determining any liability under
          the Securities Act, each filing of the registrant's annual report
          pursuant to Section 13(a) or 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 therein, and the offering of such securities at
          that time shall be deemed to be the initial bona fide offering
          thereof.

          (b) Insofar as indemnification for liabilities arising under the
Securities Act may be permitted to directors, officers and controlling persons
of the registrant pursuant to the foregoing provisions, or otherwise, the
registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the
Securities Act, and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other that the payment by the
registrant of expenses incurred or paid by a director, officer or controlling
person of such 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 Securities
Act and will be governed by the final adjudication of such issue.

          (c) The undersigned registrant hereby undertakes to respond to request
for information that is incorporated by reference into the prospectus pursuant
to Item 4, 10(b), 11, or 13 of this form, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of the registration statement through the
date of responding to the request.


                                      II-2



                                POWER OF ATTORNEY

          Each director and/or officer of the registrant whose signature appears

as his attorney-in-fact to sign in his name and behalf, in any and all
capacities stated below, and to file with the Securities and Exchange
Commission, any and all amendments, including post-effective amendments, to this
registration statement, and the registrant hereby also appoints the Agent for
Service as its attorney-in-fact with like authority to sign and file any such
amendments in its name and behalf.

          Pursuant to the requirements of the Securities Act of 1933, the
