                        Offer to Purchase for Cash Up to
          1,739,130 Shares of Delta and Pine Land Company Common Stock
  at a Purchase Price Not Greater Than $28.75 Nor Less Than $25.00 Per Share by

                          Delta and Pine Land Company


THE TENDER OFFER,  PRORATION  PERIOD AND WITHDRAWAL  RIGHTS WILL EXPIRE AT 12:00
MIDNIGHT,  NEW YORK CITY TIME,  ON  TUESDAY,  MAY 17,  2005,  UNLESS THE COMPANY
EXTENDS THE TENDER OFFER.

Delta and Pine Land Company, a Delaware corporation (referred to herein as "we,"
"us," the "Company" or "D&PL"), is offering to purchase for cash up to 1,739,130
shares of its common  stock,  upon the terms and subject to the  conditions  set
forth in this document and the letter of transmittal  (which  together,  as they
may be amended and supplemented from time to time, constitute the tender offer).

On the  terms  and  subject  to the  conditions  of the  tender  offer,  we will
determine  the single per share  price,  not  greater  than $28.75 nor less than
$25.00 per share,  net to you in cash,  without  interest,  that we will pay for
shares properly tendered and not properly withdrawn in the tender offer,  taking
into account the total number of shares so tendered and the prices  specified by
the tendering  stockholders.  We will select the lowest purchase price that will
allow us to purchase  1,739,130  shares,  or such fewer  number of shares as are
properly tendered and not properly withdrawn,  at prices not greater than $28.75
nor less than  $25.00 per share.  We will  purchase  at the  purchase  price all
shares  properly  tendered  at  prices at or below  the  purchase  price and not
properly  withdrawn,  on the terms and subject to the  conditions  of the tender
offer,  including the odd lot, conditional tender and proration  provisions.  We
reserve  the right,  in our sole  discretion,  to purchase  more than  1,739,130
shares in the tender  offer,  subject to  applicable  law. We will not  purchase
shares  tendered at prices greater than the purchase price nor shares that we do
not accept for purchase because of proration  provisions or conditional tenders.
Shares not  purchased  in the tender  offer will be  returned  to the  tendering
stockholders  at our expense  promptly after the expiration of the tender offer.
See Section 1.

THE TENDER OFFER IS NOT  CONDITIONED  UPON THE RECEIPT OF  FINANCING  NOR ON ANY
MINIMUM NUMBER OF SHARES BEING TENDERED.  THE TENDER OFFER IS, HOWEVER,  SUBJECT
TO OTHER CONDITIONS. SEE SECTION 7.

                               SUMMARY TERM SHEET

     We are providing this summary term sheet for your  convenience.  You should
realize  that it does not describe all of the details of the tender offer to the
same extent described in this document.  We urge you to read the entire document
and the letter of  transmittal  because  they  contain  the full  details of the
tender offer. We have included references to the sections of this document where
you will find a more complete discussion.

Who is  offering  to  purchase my shares?

Delta  and Pine  Land  Company,  which we refer to as  "our",  "we",  "us",  the
"Company" or "D&PL", is offering to purchase shares of its common stock.


What will the purchase price for the shares be?

We will  determine the purchase  price that we will pay per share promptly after
the tender offer expires.  The purchase price will be the lowest price at which,
based on the number of shares tendered and the prices specified by the tendering
stockholders,  we can purchase  1,739,130 shares, or such fewer number of shares
as are  properly  tendered and not properly  withdrawn  prior to the  expiration
date.  The  purchase  price will not be greater than $28.75 nor less than $25.00
per share. We will pay this purchase price in cash,  without  interest,  for all
the shares we  purchase  pursuant  to the  tender  offer,  including  the shares
tendered  at a price  below the  purchase  price.  We will not  purchase  shares
tendered  at prices  greater  than the  purchase  price or shares that we do not
purchase because of proration provisions or conditional tenders. See Section 1.


How many shares will D&PL purchase?

We will purchase 1,739,130 shares properly tendered in the tender offer, or such
fewer number of shares as are properly tendered and not properly withdrawn prior
to the expiration  date.  The 1,739,130  shares that we are offering to purchase
pursuant  to the  tender  offer  represent  approximately  4.5% of the shares of
common  stock  outstanding  as of April 13, 2005 (or  approximately  4.2% of the
shares on a diluted  basis,  assuming  the  exercise  of all  outstanding  stock
options). Additionally,  1,066,667 shares of our Series M Convertible Non-Voting
Preferred Stock were  outstanding as of April 13, 2005. The Series M Convertible
Non-Voting  Preferred  Stock is  convertible  to  shares  of  common  stock on a
one-for-one basis.

We expressly  reserve the right, to purchase an additional  number of shares not
to exceed  2% of the  outstanding  shares,  and could  decide to  purchase  more
shares,  subject to  applicable  legal  requirements.  See Section 1. The tender
offer is not conditioned upon the receipt of financing nor on any minimum number
of shares being tendered. See Section 7.

                                       1


What will  happen if more than  1,739,130  shares are  tendered  at or below the
purchase price?

If more than 1,739,130  shares are tendered at or below the purchase  price,  we
will purchase all shares tendered,  at or below the purchase price on a pro rata
basis,  except  for "odd lots"  (lots  held by owners of less than 100  shares),
which we will  purchase  on a priority  basis as  described  in the  immediately
following  paragraph and except for shares that were conditionally  tendered and
for which the condition was not satisfied. See Sections 5 and 6.


If I own fewer than 100 shares and I tender all of my shares,  will I be subject
to proration?

If you own beneficially or of record fewer than 100 shares in the aggregate, you
properly  tender all of these shares at or below the  purchase  price before the
tender offer  expires and you complete  the section  entitled  "Odd Lots" in the
letter of  transmittal,  we will purchase all of your shares without  subjecting
them to the proration procedure. See Section 1.


How will D&PL pay for the shares?

We  anticipate  that we will fund the  purchase  of the shares  tendered  in the
tender offer through cash on hand. See Section 9.


How long do I have to tender my shares?

You may tender your shares until the tender offer expires. The tender offer will
expire on Tuesday,  May 17, 2005, at 12:00 Midnight,  New York City time, unless
we extend  it. See  Section 1. We may choose to extend the tender  offer for any
reason, subject to applicable laws. We cannot assure you that we will extend the
tender offer or indicate the length of any  extension  that we may provide.  See
Section 15. If a broker, dealer, commercial bank, trust company or other nominee
holds your shares,  it is likely they have an earlier deadline for you to act to
instruct them to accept the tender offer on your behalf.  We urge you to contact
the broker, dealer,  commercial bank, trust company or other nominee to find out
their deadline.


Can the  tender  offer be  extended,  amended  or  terminated,  and  under  what
circumstances?

We can extend or amend the tender offer in our sole discretion. If we extend the
tender  offer,  we will  delay  the  acceptance  of any  shares  that  have been
tendered.  We can terminate the tender offer under  certain  circumstances.  See
Section 7 and Section 15.

                                       2


How will I be notified if D&PL  extends the tender  offer or amends the term sof
the tender offer?

If we decide to extend the tender offer, we will issue a press release not later
than 9:00 a.m.,  New York City time,  on the  business  day after the  scheduled
expiration  date. We will announce any amendment to the tender offer by making a
public  announcement  of  the  amendment  and/or  filing  amended  tender  offer
documents  with the  Securities  and  Exchange  Commission.  We post  our  press
releases and filings with the Securities and Exchange  Commission on our website
at www.deltaandpine.com. See Section 15.


What is the purpose of the tender offer?

We believe  that the tender  offer is a prudent use of our  financial  resources
given our strong cash position and expected future cash flows, business profile,
assets and the  current  market  price of our  common  stock.  The tender  offer
represents an  opportunity  for us to return cash to  stockholders  who elect to
tender  their  shares,   while  at  the  same  time   increasing   non-tendering
stockholders' proportionate interest in D&PL. See Section 2 and Section 10.


Are there any conditions to the tender offer?

Yes. The tender offer is subject to conditions, such as the absence of court and
governmental  action  prohibiting  the  tender  offer and of  changes in general
market  conditions  or  our  business  that,  in  our  judgment,  are  or may be
materially adverse to us. See Section 7.


Following the tender offer, will D&PL continue as a public company?

Yes.  Following the completion of the tender offer in accordance  with its terms
and  conditions,  D&PL's common stock will continue to be listed on the New York
Stock  Exchange and D&PL will  continue to be subject to the periodic  reporting
requirements  of the Securities  Exchange Act of 1934, as amended (the "Exchange
Act"). See Section 12.


How do I tender  my  shares?

The tender offer will expire at 12:00 Midnight,  New York City time, on Tuesday,
May 17, 2005, unless we extend the tender offer. To tender your shares, prior to
the expiration of the tender offer:

- -    you must deliver your share  certificate(s)  and a properly  completed  and
     duly  executed  letter of  transmittal  to the  depositary  at the  address
     appearing on the back cover page of this document; or

- -    the  depositary  must receive a  confirmation  of receipt of your shares by
     book-entry  transfer and a properly  completed and duly executed  letter of
     transmittal or an agent's message in the case of a book-entry transfer; or

                                       3


- -    you must request a broker, dealer,  commercial bank, trust company or other
     nominee to effect the transaction for you; or

- -    you must  comply  with the  guaranteed  delivery  procedures  described  in
     Section 3.

You should contact the information agent or the dealer manager for assistance at
their  respective  addresses and  telephone  numbers set forth on the back cover
page of this  document.  See  Section 3 and the  instructions  to the  letter of
transmittal.  Please note that D&PL will not purchase  your shares in the tender
offer  unless  the  depositary  receives  the  required  documents  prior to the
expiration of the tender offer.  If a broker,  dealer,  commercial  bank,  trust
company or other  nominee  holds your shares,  it is likely they have an earlier
deadline  for you to act to  instruct  them to accept the  tender  offer on your
behalf.  We urge you to contact  your broker,  dealer,  commercial  bank,  trust
company or other nominee to find out their applicable deadline.


Once I have  tendered  shares in the tender  offer,  can I withdraw  my tendered
shares?

Yes.  You may  withdraw  any shares  you have  tendered  at any time  before the
expiration of the tender offer which will occur at 12:00 Midnight, New York City
time, on Tuesday, May 17, 2005, unless we extend the tender offer, in which case
you can  withdraw  your  shares  until the  expiration  of the  tender  offer as
extended.  In  addition,  after our offer  expires,  if we have not accepted for
payment the shares you have  tendered to us, you may withdraw your shares at any
time after 12:00 Midnight, New York City time, on Wednesday,  June 15, 2005. See
Section 4.


How do I withdraw shares I previously tendered?

You must  deliver,  on a timely  basis,  a written or  facsimile  notice of your
withdrawal to the depositary at the address  appearing on the back cover page of
this document.  Your notice of withdrawal  must specify your name, the number of
shares to be withdrawn  and the name of the  registered  holder of these shares.
Some  additional  requirements  apply if the share  certificates to be withdrawn
have been delivered to the depositary or if your shares have been tendered under
the procedure for book-entry transfer set forth in Section 3. See Section 4.

                                       4


How do holders of vested  stock  options  for shares  participate  in the tender
offer?

If you hold vested but  unexercised  options,  you may exercise such options for
cash in  accordance  with the terms of the  applicable  stock  option  plans and
tender the shares  received upon such  exercise in  accordance  with this tender
offer.  An exercise of an option cannot be revoked even if shares  received upon
the exercise  thereof and  tendered in the offer are not  purchased in the offer
for any reason. See Section 3.


Has D&PL or its Board of Directors adopted a position on the tender offer?

Our Board of Directors  has approved the tender offer.  However,  neither we nor
our Board of Directors nor the dealer manager makes any recommendation to you as
to whether you should tender or refrain from  tendering your shares or as to the
price or prices at which you may  choose to tender  your  shares.  You must make
your own  decision  as to whether to tender  your  shares  and,  if so, how many
shares to tender and the price or prices at which to tender your  shares.  In so
doing,  you should read carefully the  information in this offer to purchase and
in the letter of transmittal, including our reasons for making the tender offer.
Of our directors and executive  officers,  one executive  officer has advised us
that he  intends to tender a portion  of his  shares in the  tender  offer.  See
Section 2 and Section 11.


If I decide not to tender,  how will the tender offer affect my shares?

Stockholders who choose not to tender will own a greater percentage  interest in
our outstanding common stock following the consummation of the tender offer.


What is the recent market price for the shares?

We publicly  announced the tender offer on April 20, 2005, before the opening of
trading on the New York Stock Exchange on that date. On April 15, 2005, the last
trading day prior to printing this offer to purchase, the reported closing price
of our common  stock on the NYSE was  $25.68  per  share.  We urge you to obtain
current market quotations for our common stock. See Section 8.


When will D&PL pay for the shares I tender?

We will pay the purchase price, net to you in cash,  without  interest,  for the
shares we purchase  promptly  after the  expiration  of the tender offer and the
acceptance of the shares for payment;  provided,  however, that we do not expect
to announce the results of the  proration  and begin paying for tendered  shares
until at least five business days after the expiration of the tender offer.  See
Section 5.


Will I have to pay brokerage commissions if I tender my shares?

If you are a registered  stockholder  and you tender your shares directly to the
depositary,  you will not incur any  brokerage  commissions.  If you hold shares
through  a  broker  or bank,  we urge  you to  consult  your  broker  or bank to
determine whether transaction costs are applicable. See Section 3.

                                       5


What are the U.S. federal income tax consequences if I tender my shares?

Generally,  you will be subject to U.S. federal income taxation when you receive
cash from us in exchange for the shares you tender. The receipt of cash for your
tendered  shares  will be  treated  either  as (1) a sale or  exchange  or (2) a
distribution  from us in  respect of our  stock.  Holders  of shares,  including
holders who are not U.S.  holders,  should  consult their tax advisors as to the
particular  consequences  to them of  participation  in the  tender  offer.  See
Section 14.


Will I have to pay any stock transfer tax if I tender my shares?

If you instruct the  depositary in the letter of transmittal to make the payment
for the shares to the registered  holder,  you will not incur any stock transfer
tax. See Section 5.


Who can help answer my questions about the tender offer?

The information agent or the dealer manager can help answer your questions.  The
information agent is Georgeson  Shareholder  Communications  Inc. and the dealer
manager is UBS  Securities  LLC.  Their contact  information is set forth on the
back cover page of this document.

                           FORWARD-LOOKING STATEMENTS

     This offer to  purchase  contains or  incorporates  by  reference  not only
historical  information,  but also  forward-looking  statements  relating to our
operations   that  are  based  on  our  current   expectations,   estimates  and
projections.  Words such as "anticipates," "believes," "continues," "estimates,"
"expects,"  "goal,"  "intends,"  "may,"  "opportunity,"   "plans,"  "potential,"
"projects,"  "forecasts," "should," "will," and similar expressions are intended
to identify such forward-looking statements. These statements are not guarantees
of future performance and involve risks, uncertainties, and assumptions that are
difficult to predict.  Forward-looking  statements are based upon assumptions as
to future events that may not prove to be accurate.  Actual outcomes and results
may  differ   materially   from  what  is  expressed  or   forecasted  in  these
forward-looking statements.

     Our actual results may differ from the forward-looking  statements for many
reasons, including:

    -     Demand  for our seed  will be  affected  by  government  programs  and
          policies  and by  weather.  Demand  for  seed  is also  influenced  by
          commodity prices,  the cost of other crop inputs, and the demand for a
          crop's  end-uses such as textiles,  animal feed,  cottonseed oil, food
          and raw  materials  for  industrial  use.  These  factors,  along with
          weather,  influence the cost and  availability  of seed for subsequent
          seasons.  Weather  impacts  crop  yields,  commodity  prices  and  the
          planting  decisions that farmers make regarding both original planting
          commitments and, when necessary, replanting levels.

    -     The planting seed market is highly competitive,  and our products face
          competition  from a number  of seed  companies,  diversified  chemical
          companies, agricultural biotechnology companies, governmental agencies
          and academic  and  scientific  institutions.  A number of chemical and
          biotechnology  companies  have  seed  production  and/or  distribution
          capabilities  to ensure  market  access for new seed  products and new
          technologies  that may compete with the Bollgard(R)  ("Bollgard")  and
          Roundup  Ready(R)  ("Roundup  Ready")  gene  technologies  of Monsanto
          Company ("Monsanto"),  our principal licensor of such technology.  Our
          seed  products  and  technologies   contained  therein  may  encounter
          substantial  competition  from  technological  advances  by  others or
          products from new market entrants. Many of our competitors are, or are
          affiliated with, large diversified  companies that have  substantially
          greater resources than we have.

    -     We  currently  are  engaged in a dispute  resolution  and  arbitration
          process  with   Monsanto,   the  principal   licensor  of  our  cotton
          technology. In the arbitration, Monsanto is seeking a determination by
          the arbitrators of its right to terminate certain  agreements  between
          our companies,  including the Bollgard and Roundup Ready licenses.  In
          addition,  we  are  currently  engaged  in  litigation  with  Monsanto
          concerning  the  failed  merger of the  companies.  The result of this
          litigation (and the process of litigating)  may materially  affect the
          results of our business.

    -     There is no  assurance  that new  technologies,  such as the  DeltaMax
          Cotton,  LLC and Syngenta  technologies,  will result in  commercially

                                       7


          viable  products or that such  technologies  are developed in the time
          frame or for the amounts  estimated  to  complete.  Also,  there is no
          assurance that regulatory approval will be obtained for the products.

    -     The  production,  distribution  or sale of crop seed in or to  foreign
          markets may be subject to special  risks,  including  fluctuations  in
          foreign    currency,    exchange   rate    controls,    expropriation,
          nationalization and other agricultural,  economic,  tax and regulatory
          policies of foreign governments and shipping  disruptions.  Particular
          policies  which may affect our domestic and  international  operations
          include the use of and the  acceptance  of products that were produced
          from  plants  that  have  been  genetically  modified,   the  testing,
          quarantine and other restrictions relating to the import and export of
          plants and seed  products and the  availability  (or lack  thereof) of
          proprietary protection for plant products. In addition,  United States
          government  policies,  particularly  those affecting foreign trade and
          investment, may impact our international operations.

    -     The publicity related to genetically  modified  organisms  ("GMOs") or
          products  made from plants that contain GMOs may have an effect on our
          sales in the future. In 2004, approximately 94% of our cottonseed that
          was sold in the United States  contained  either or both of Monsanto's
          Bollgard and Roundup Ready gene  technologies,  and 95% of our soybean
          seed sales contained the Roundup Ready gene technology.  Although many
          farmers have rapidly adopted these  technologies,  the concern of some
          customers  and  governmental  entities  over  finished  products  that
          contain  GMOs could  impact  demand for crops  (and  ultimately  seed)
          raised from seed containing such traits.

    -     Due to the varying levels of  agricultural  and social  development of
          the  international  markets in which we operate and because of factors
          within the particular  international markets we target,  international
          profitability  and growth  may be less  stable  and  predictable  than
          domestic profitability and growth. Furthermore, recent action taken by
          the U.S. government,  including that taken by the U.S. military in the
          aftermath of the tragic events of September 11, 2001, the war in Iraq,
          and conflicts  between major cotton  producing  nations,  may serve to
          further  complicate  our  ability  to execute  our long range  ex-U.S.
          business  plans  because  those plans include  future  expansion  into
          Uzbekistan, Pakistan and India. World health concerns about infectious
          diseases also affect the conduct of our international business.

    -     Our  customers  in many  markets,  including  the U.S.,  benefit  from
          government  subsidy  programs.  The Farm Security and Rural Investment
          Act of 2002 expires on January 1, 2007 (although this act includes the
          2007 cotton planting  season),  and future U.S. farm subsidy  programs
          are  uncertain.  Various  other  countries  have  challenged,  and may
          continue to challenge,  the  appropriateness  of U.S.  farm  subsidies
          through  the World Trade  Organization  ("WTO") or other  forums.  The
          outcome  of  these  challenges  has not yet been  determined,  but may
          negatively  impact U.S.  farmers.  U.S.  farm programs and WTO rulings
          impacting  such  programs  may  materially  affect the  results of our
          business.

                                       8


    -     Overall  profitability  will depend on the factors noted above as well
          as weather  conditions,  government policies in all countries where we
          sell products and operate,  worldwide commodity prices, our ability to
          successfully  open new international  markets,  our ability to develop
          the Texas High Plains  market,  the  technology  partners'  ability to
          obtain timely  government  approval  (and maintain such  approval) for
          existing and for additional  biotechnology  products on which they and
          D&PL are working,  our technology  partners'  ability to  successfully
          defend challenges to proprietary  technologies  licensed to us and our
          ability to produce  sufficient  commercial  quantities of high quality
          planting  seed  of  these  products.  Any  delay  in or  inability  to
          successfully  complete these projects may affect future profitability.
          In  addition,  earnings  forecasts  do  not  consider  the  impact  of
          potential  transactions,  their related  accounting and other factors,
          that may be under consideration by the Company,  but have not yet been
          completed  or their  effect  determined  at the  date of a  particular
          filing.

     For  a  more  detailed  discussion  of  these  and  other  risks,  see  the
information  under the heading "Risk and  Uncertainties" in our Annual Report on
Form 10-K.

                                  INTRODUCTION

To the Holders of our common stock:

     We invite our stockholders to tender shares of our common stock, with a par
value of $0.10 per share,  for purchase by us. Upon the terms and subject to the
conditions set forth in this offer to purchase and in the letter of transmittal,
we are offering to purchase up to  1,739,130  shares of our common  stock,  at a
price not greater than $28.75 nor less than $25.00 per share,  net to the seller
in cash, without interest.

     The tender  offer will  expire at 12:00  Midnight,  New York City time,  on
Tuesday,  May 17, 2005,  unless extended (such date and time, as the same may be
extended,  the "expiration  date").  We may, in our sole discretion,  extend the
period of time in which the tender offer will remain open.

     We will  select  the  lowest  purchase  price  that  will  allow  us to buy
1,739,130  shares,  or, if a lesser number of shares is properly  tendered,  all
shares that are properly  tendered and not properly  withdrawn.  We will acquire
all shares  that we  purchase  in the tender  offer at the same  purchase  price
regardless  of whether  the  stockholder  tendered  at a lower  price.  However,
because of the "odd lot" priority,  proration and conditional  tender provisions
described  in this  offer to  purchase,  we may not  purchase  all of the shares
tendered  at or below the  purchase  price if more than the  number of shares we
seek are  properly  tendered.  We will not  purchase  shares  tendered at prices
greater  than the  purchase  price or shares that we do not accept for  purchase
because of proration  provisions or conditional tenders. We will return tendered
shares that we do not  purchase  to the  tendering  stockholders  at our expense
promptly after the expiration of the tender offer. See Section 1.

     We  reserve  the  right,  in our sole  discretion,  to  purchase  more than
1,739,130  shares pursuant to the tender offer,  subject to certain  limitations
and legal requirements. See Section 1.

     Stockholders  must  complete  the  section  of the  letter  of  transmittal
relating  to the price at which they are  tendering  shares in order to properly
tender shares.

     We will pay the purchase price, net to the tendering  stockholders in cash,
without interest, for all shares that we purchase.  Tendering stockholders whose
shares are  registered  in their own names and who tender  directly  to Illinois
Stock  Transfer  Company,  the  depositary  in the  tender  offer,  will  not be
obligated  to pay  brokerage  fees or  commissions  or,  except  as set forth in
Instruction 9 to the letter of transmittal, stock transfer taxes on the purchase
of shares by us pursuant to the tender offer.  If you own your shares  through a
bank,  broker,  dealer,  trust company or other nominee and that person  tenders
your shares on your  behalf,  that person may charge you a fee for doing so. You
should  consult your bank,  broker,  dealer,  trust  company or other nominee to
determine whether any charges will apply.

     The tender offer is not conditioned upon the receipt of financing or on any
minimum number of shares being tendered.  The tender offer is, however,  subject
to certain other conditions. See Section 7.

                                       10


     OUR BOARD OF DIRECTORS HAS APPROVED THE TENDER OFFER.  HOWEVER,  NEITHER WE
NOR OUR BOARD OF DIRECTORS NOR THE DEALER  MANAGER MAKES ANY  RECOMMENDATION  TO
YOU AS TO WHETHER YOU SHOULD TENDER OR REFRAIN FROM  TENDERING YOUR SHARES OR AS
TO THE PRICE OR PRICES AT WHICH YOU MAY CHOOSE TO TENDER YOUR  SHARES.  YOU MUST
MAKE YOUR OWN  DECISION AS TO WHETHER TO TENDER YOUR SHARES AND, IF SO, HOW MANY
SHARES TO TENDER AND THE PRICE OR PRICES AT WHICH TO TENDER YOUR  SHARES.  IN SO
DOING,  YOU SHOULD READ CAREFULLY THE  INFORMATION IN THIS OFFER TO PURCHASE AND
IN THE LETTER OF TRANSMITTAL, INCLUDING OUR REASONS FOR MAKING THE TENDER OFFER.
OF OUR DIRECTORS AND EXECUTIVE  OFFICERS,  ONE EXECUTIVE  OFFICER HAS ADVISED US
THAT HE  INTENDS TO TENDER A PORTION  OF HIS  SHARES IN THE  TENDER  OFFER.  SEE
SECTION 2 AND SECTION 11.

     If, at the expiration  date,  more than  1,739,130  shares (or such greater
number of shares as we may elect to  purchase,  subject to  applicable  law) are
properly tendered at or below the purchase price and not properly withdrawn,  we
will buy shares:

     -    first,  from all  holders  of "odd  lots"  (holders  of less  than 100
          shares)  who  properly  tender  all of their  shares  at or below  the
          purchase price selected by us and do not properly withdraw them before
          the expiration date;

     -    second,  on a pro rata basis from all other  stockholders who properly
          tender  shares at or below the  purchase  price  selected by us, other
          than  stockholders who tender  conditionally  and whose conditions are
          not satisfied; and

     -    third, only if necessary to permit us to purchase 1,739,130 shares (or
          such greater number of shares as we may elect to purchase,  subject to
          applicable  law) from holders who have tendered shares at or below the
          purchase  price  subject to the  condition  that a  specified  minimum
          number of the  holder's  shares be  purchased  if any of the  holder's
          shares are  purchased in the tender offer (for which the condition was
          not initially satisfied) by random lot, to the extent feasible.  To be
          eligible  for  purchase by random lot,  stockholders  whose shares are
          conditionally tendered must have tendered all of their shares.

     We may not purchase all of the shares tendered pursuant to the tender offer
even if the shares are tendered at or below the purchase  price.  See Section 1,
Section 5 and Section 6,  respectively,  for additional  information  concerning
priority, proration and conditional tender procedures.

     Section  14 of this  offer to  purchase  describes  various  United  States
federal  income  tax  consequences  of a sale of shares  pursuant  to the tender
offer.

     Holders of vested but  unexercised  options to purchase shares may exercise
such  options  for cash and tender  some or all of the shares  issued  upon such
exercise.  An exercise of an option  cannot be revoked  even if shares  received
upon the  exercise  thereof and  tendered in the offer are not  purchased in the
offer for any reason.

                                       11


     As of April 13, 2005, D&PL had 38,479,224 shares outstanding. The 1,739,130
shares that we are offering to purchase  pursuant to the tender offer  represent
approximately  4.5% of the shares of common stock  outstanding  as of that date.
Our common  stock is listed and traded on the NYSE under the symbol  "DLP".  See
Section 8. On April 15, 2005, the last trading day prior to the printing of this
offer to purchase,  the reported  closing  price of our common stock on the NYSE
was $25.68.  We urge  stockholders  to obtain current market  quotations for our
common stock.

                                THE TENDER OFFER

1.   Number of Shares; Proration.

     General.  Upon the terms and subject to the conditions of the tender offer,
D&PL will purchase  1,739,130  shares of common  stock,  or such fewer number of
shares as are properly  tendered and not properly  withdrawn in accordance  with
Section 4 before the scheduled  expiration  date of the tender offer, at a price
not greater  than  $28.75 nor less than  $25.00 per share,  net to the seller in
cash, without interest.

     The term  "expiration  date" means 12:00  Midnight,  New York City time, on
Tuesday,  May 17, 2005, unless D&PL, in its sole discretion,  extends the period
of time during which the tender offer will remain open,  in which event the term
"expiration  date"  shall  refer to the latest time and date at which the tender
offer, as so extended by D&PL, shall expire. See Section 15 for a description of
D&PL's  right  to  extend,  delay,  terminate  or amend  the  tender  offer.  In
accordance with the rules of the Securities and Exchange  Commission,  D&PL may,
and D&PL expressly  reserves the right to purchase  pursuant to the tender offer
an  additional  number of shares  not to  exceed  2% of the  outstanding  shares
without  amending or extending the tender offer. See Section 15. In the event of
an  over-subscription of the tender offer as described below, shares tendered at
or below the purchase  price will be subject to proration,  except for odd lots.
The proration period and, except as described herein,  withdrawal rights, expire
on the expiration date.

     If we:

     -    increase  the price to be paid for  shares  above  $28.75 per share or
          decrease the price to be paid for shares below $25.00 per share, or

     -    increase  the number of shares  being  sought in the tender  offer and
          this  increase  in the  number  of  shares  sought  exceeds  2% of the
          outstanding shares, or

     -    decrease the number of shares being sought, and

     -    the tender  offer is  scheduled to expire at any time earlier than the
          expiration  of a period  ending on the tenth  business  day from,  and
          including, the date that we first publish, send or give notice, in the
          manner specified in Section 15, of any increase or decrease,

then we will extend the tender offer until the  expiration  of ten business days
from the date that we first publish notice of any increase or decrease.  For the

                                       12


purposes  of the  tender  offer,  a  "business  day"  means any day other than a
Saturday,  Sunday or U.S.  federal  holiday and consists of the time period from
12:01 a.m. through 12:00 Midnight, New York City time.

     The tender offer is not conditioned upon the receipt of financing or on any
minimum number of shares being tendered.  The tender offer is, however,  subject
to other conditions. See Section 7.

     In accordance with Instruction 5 of the letter of transmittal, stockholders
desiring to tender  shares must  specify the price or prices,  not greater  than
$28.75 nor less than  $25.00 per share,  at which they are willing to sell their
shares  to  D&PL  pursuant  to the  tender  offer.  Alternatively,  stockholders
desiring  to tender  shares can  choose  not to  specify a price  and,  instead,
specify  that they will  sell  their  shares  at the  purchase  price  that D&PL
ultimately pays for shares properly  tendered and not properly  withdrawn in the
tender offer, which could result in the tendering  stockholder receiving a price
per share as low as $25.00 or as high as $28.75. If tendering  stockholders wish
to maximize the chance that D&PL will purchase  their shares,  they should check
the box in the section of the letter of transmittal  captioned  "Shares Tendered
at Price Determined Pursuant to the Tender Offer." Note that this election could
result in the tendered shares being purchased at the minimum price of $25.00 per
share. This election could also have the effect of decreasing the price at which
D&PL purchases  tendered shares because shares tendered using this election will
be available for purchase at the minimum price of $25.00 per share.

     To tender  shares  properly,  stockholders  must specify one, and only one,
price box in the  appropriate  section  in each  letter of  transmittal.  If you
specify  more  than one  price or if you fail to check any price at all you will
not have validly tendered your shares. See Section 3.

     Promptly  following the expiration date, D&PL will, in its sole discretion,
determine the purchase price that it will pay for shares  properly  tendered and
not properly  withdrawn in the tender  offer,  taking into account the number of
shares tendered and the prices  specified by tendering  stockholders.  D&PL will
select the lowest purchase  price,  not greater than $28.75 nor less than $25.00
per share, net to the seller in cash,  without interest,  that will enable it to
purchase  1,739,130  shares,  or such  fewer  number of  shares as are  properly
tendered and not properly  withdrawn in the tender offer. D&PL will purchase all
shares  properly  tendered  at or below the  purchase  price  (and not  properly
withdrawn),  all at the same purchase  price,  upon the terms and subject to the
conditions of the tender offer, including the odd lot, proration and conditional
tender provisions.

     D&PL will not purchase  shares tendered at prices greater than the purchase
price  and  shares  that it does not  accept  in the  tender  offer  because  of
proration provisions or conditional  tenders.  D&PL will return to the tendering
stockholders  shares  that it does not  purchase  in the tender  offer at D&PL's
expense promptly after the expiration date. By following the instructions to the
letter  of  transmittal,  stockholders  can  specify  one  minimum  price  for a
specified  portion  of their  shares  and a  different  minimum  price for other
specified shares,  but stockholders must submit a separate letter of transmittal
for shares  tendered at each price.  Stockholders  also can specify the order in

                                       13


which D&PL will  purchase  the  specified  portions of their shares in the event
that, as a result of the proration provisions or otherwise,  D&PL purchases some
but not all of the tendered shares pursuant to the tender offer.

     If the number of shares  properly  tendered at or below the purchase  price
and not properly  withdrawn  prior to the expiration date is fewer than or equal
to  1,739,130  shares,  or such  greater  number  of shares as D&PL may elect to
purchase,  subject to applicable  law, D&PL will,  upon the terms and subject to
the conditions of the tender offer, purchase all such shares.

     Priority of Purchases.  Upon the terms and subject to the conditions of the
tender offer, if greater than 1,739,130 shares, or such greater number of shares
as D&PL may elect to purchase,  subject to  applicable  law,  have been properly
tendered at prices at or below the purchase  price,  and not properly  withdrawn
prior to the expiration date, D&PL will purchase properly tendered shares on the
basis set forth below:

     -    First,  we will  purchase  all shares  tendered by all holders of "odd
          lots" who:

          -    tender all shares owned  beneficially  or of record at a price at
               or below the purchase price selected by us (partial  tenders will
               not qualify for this preference); and

          -    complete  the  section  entitled  "Odd  Lots"  in the  letter  of
               transmittal  and,  if  applicable,  in the  notice of  guaranteed
               delivery.

     -    Second,  subject to the  conditional  tender  provisions  described in
          Section 6, we will purchase all other shares  tendered at prices at or
          below the  purchase  price  selected by us on a pro rata  basis,  with
          appropriate  adjustments to avoid purchases of fractional  shares,  as
          described below.

     -    Third, only if necessary to permit us to purchase 1,739,130 shares (or
          such greater number of shares as we may elect to purchase,  subject to
          applicable  law),  shares   conditionally   tendered  (for  which  the
          condition was not initially  satisfied) at or below the purchase price
          selected by us, will, to the extent feasible, be selected for purchase
          by random lot. To be eligible for purchase by random lot, stockholders
          whose  shares are  conditionally  tendered  must have  tendered all of
          their shares.

     D&PL may not purchase all of the shares that a  stockholder  tenders in the
tender offer even if they are tendered at prices at or below the purchase price.
It is also possible that D&PL will not purchase any of the shares  conditionally
tendered  even  though  those  shares  were  tendered  at prices at or below the
purchase price.

     Odd Lots. For purposes of the tender offer,  the term "odd lots" shall mean
all shares properly  tendered prior to the expiration date at prices at or below
the purchase price and not properly  withdrawn by any person,  referred to as an
"odd lot" holder,  who owns beneficially or of record an aggregate of fewer than
100  shares  and so  certifies  in  the  appropriate  place  on  the  letter  of
transmittal and, if applicable, on the notice of guaranteed delivery. To qualify
for this preference, an odd lot holder must tender all shares owned beneficially
or of record by the odd lot holder in accordance  with the procedures  described
in Section 3. As set forth above,  D&PL will accept odd lots for payment  before

                                       14


proration,  if any, of the purchase of other tendered shares. This preference is
not  available  to partial  tenders  or to  beneficial  or record  holders of an
aggregate of 100 or more shares,  even if these holders have share  certificates
representing  fewer than 100 shares.  By accepting the tender offer,  an odd lot
holder  who holds  shares in its name and  tenders  its shares  directly  to the
depositary would not only avoid the payment of brokerage  commissions,  but also
would avoid any  applicable  odd lot discounts in a sale of the odd lot holder's
shares on the NYSE.  Any odd lot  holder  wishing  to tender  all of its  shares
pursuant to the tender offer should complete the section  entitled "Odd Lots" in
the letter of  transmittal  and,  if  applicable,  in the  notice of  guaranteed
delivery.

     Proration. If proration of tendered shares is required, D&PL will determine
the  proration  factor as soon as  practicable  following the  expiration  date.
Subject to adjustment to avoid the purchase of fractional  shares and subject to
the  provisions  governing  conditional  tenders  described in Section 6 of this
offer to purchase,  proration for each  stockholder  that tenders shares will be
based on the ratio of the total  number of shares  that we accept  for  purchase
(excluding "odd lots") to the total number of shares properly  tendered (and not
properly  withdrawn) at or below the purchase price by all  stockholders  (other
than "odd lot" holders).

     Because of the  difficulty  in  determining  the number of shares  properly
tendered,  including  shares  tendered by  guaranteed  delivery  procedures,  as
described in Section 3, and not properly  withdrawn,  and because of the odd lot
procedure and conditional tender  provisions,  D&PL does not expect that it will
be able to  announce  the final  proration  factor or  commence  payment for any
shares purchased  pursuant to the tender offer until at least five business days
after the  expiration  date.  The  preliminary  results of any proration will be
announced by press release promptly after the expiration date.  Stockholders may
obtain  preliminary  proration  information  from the  information  agent or the
dealer manager and may be able to obtain this information from their brokers.

     As  described  in Section 14, the number of shares that D&PL will  purchase
from a stockholder under the tender offer may affect the U.S. federal income tax
consequences  to  that  stockholder  and,  therefore,  may be  relevant  to that
stockholder's decision whether or not to tender shares.

     We will mail this offer to purchase and the letter of transmittal to record
holders  of shares  and we will  furnish  this  offer to  purchase  to  brokers,
dealers, commercial banks and trust companies whose names, or the names of whose
nominees,  appear on D&PL's stockholder list or, if applicable,  that are listed
as participants in a clearing  agency's security position listing for subsequent
transmittal to beneficial owners of shares.

2.   Purpose of the Tender Offer.

     D&PL  believes  that the  tender  offer is a prudent  use of its  financial
resources  given its strong  cash  position  and  expected  future  cash  flows,
business  profile,  assets and the current market price of its common stock. The
tender offer  represents an opportunity  for D&PL to return cash to stockholders
who elect to tender their  shares.  Where shares are tendered by the  registered
owner of those shares  directly to the  depositary,  the sale of those shares in
the tender  offer will  permit the seller to avoid the usual  transaction  costs

                                       15


associated with open market sales. Furthermore,  odd lot holders who hold shares
registered in their names and tender their shares directly to the depositary and
whose shares are purchased  pursuant to the tender offer will avoid not only the
payment of brokerage  commissions but also any applicable odd lot discounts that
might be payable on sales of their shares in NYSE transactions.

     Stockholders  who do not tender their  shares  pursuant to the tender offer
and  stockholders who otherwise retain an equity interest in D&PL as a result of
a partial  tender of shares,  proration  or a  conditional  tender for which the
condition is not satisfied will continue to be owners of D&PL and will realize a
proportionate  increase in their relative  equity interest in D&PL and will bear
the risks and  rewards  associated  with owning the equity  securities  of D&PL,
including risks resulting from D&PL's purchase of shares.

     Our offer also presents some potential  risks and  disadvantages  to us and
our continuing stockholders.  Our offer will reduce our "public float"; that is,
the number of shares owned by outside  stockholders and available for trading in
the  securities  markets.  This may  result in lower  stock  prices  or  reduced
liquidity in the trading market for our shares in the future. See Section 12.

     After the completion of the tender offer,  D&PL expects to have  sufficient
cash flow and access to funding to meet its cash needs for normal operations and
anticipated capital expenditures.

     Neither D&PL nor the D&PL Board of Directors  nor the dealer  manager makes
any  recommendation  to any  stockholder as to whether to tender or refrain from
tendering  any  shares or as to the price or  prices at which  stockholders  may
choose to tender their shares.  D&PL has not  authorized  any person to make any
recommendation.  Stockholders  should carefully  evaluate all information in the
tender offer,  should consult their own investment and tax advisors,  and should
make their own decisions  about whether to tender  shares,  and, if so, how many
shares to tender  and the  price or  prices  at which to  tender.  D&PL has been
advised that of its  directors  and executive  officers,  one executive  officer
intends to tender a portion of his shares in the tender offer.

     D&PL may make stock repurchases from time to time on the open market and/or
in private  transactions.  In February  2000,  D&PL  announced that its Board of
Directors  had  authorized  the Company to  repurchase  up to $50 million of its
common  stock.  The  repurchased  shares  are to be used to  provide  for option
exercises  and for  other  general  corporate  purposes.  D&PL  has  repurchased
approximately   $47.5  million  of  its  common  stock  under  this   repurchase
authorization.  Whether or not D&PL makes additional  repurchases will depend on
many factors, including,  without limitation, the number of shares, if any, that
D&PL purchases in this tender offer,  D&PL's business and financial  performance
and  situation,  the business and market  conditions at the time,  including the
price of the shares, and such other factors as D&PL may consider  relevant.  Any
of these  repurchases may be on the same terms or on terms that are more or less
favorable to the selling  stockholders  than the terms of the tender offer. Rule
13e-4 of the Exchange Act prohibits D&PL and its affiliates  from purchasing any
shares,  other than  pursuant to the tender  offer,  until at least ten business
days after the expiration  date of the tender offer,  except pursuant to certain
limited exceptions provided in Rule 14e-5 of the Exchange Act.

                                       16


     D&PL  intends  to treat as  treasury  stock  the  shares  that it  acquires
pursuant to the tender offer. These shares will be available for D&PL to reissue
without further  stockholder action (except as required by applicable law or the
rules of the NYSE or any other securities  exchange on which the shares may then
be listed) for various purposes  including,  without  limitation,  acquisitions,
raising additional capital and the satisfaction of obligations under existing or
future employee benefit or compensation  programs or stock plans or compensation
programs for directors.

3.   Procedures for Tendering Shares.

     Proper  Tender of  Shares.  For  stockholders  to  properly  tender  shares
pursuant to the tender offer:

     -    the depositary must receive, at the depositary's  address set forth on
          the back cover page of this offer to purchase,  share certificates (or
          confirmation  of  receipt  of such  shares  under  the  procedure  for
          book-entry  transfer  set  forth  below),  together  with  a  properly
          completed  and duly  executed  letter of  transmittal,  including  any
          required signature guarantees,  or an "agent's message" in the case of
          a book-entry  transfer and any other documents  required by the letter
          of transmittal, before the tender offer expires; or

     -    the tendering  stockholder  must comply with the  guaranteed  delivery
          procedure set forth below.

     If a broker, dealer,  commercial bank, trust company or other nominee holds
your  shares,  it is likely  they  have an  earlier  deadline  for you to act to
instruct them to accept the tender offer on your behalf.  We urge you to contact
your broker, dealer, commercial bank, trust company or other nominee to find out
their applicable deadline.

     In accordance with Instruction 5 of the letter of transmittal, stockholders
desiring  to tender  shares in the  tender  offer  must  properly  indicate  the
purchase price they will accept for their tendered shares by either (i) checking
the box in the section captioned  "Shares Tendered at Price Determined  Pursuant
to the Tender Offer" in the letter of  transmittal,  which means the stockholder
is willing to accept the  purchase  price  determined  by D&PL  pursuant  to the
tender  offer,  or (ii)  checking one, and only one, of the boxes in the section
captioned  "Shares Tendered at Price Determined by Stockholder" in the letter of
transmittal  indicating the price per share at which such  stockholder's  shares
are being tendered.

     If  tendering  stockholders  wish to  maximize  the  chance  that D&PL will
purchase their shares, they should check the box in the section of the letter of
transmittal  captioned  "Shares  Tendered  at Price  Determined  Pursuant to the
Tender  Offer." Note that this election  could have the effect of decreasing the
price at which D&PL purchases tendered shares because shares tendered using this
election will be available for purchase at the minimum price of $25.00 per share
and,  as a result,  it is  possible  that  this  election  could  result in D&PL
purchasing tendered shares at the minimum price of $25.00 per share.

                                       17


     A  stockholder  who  desires  to tender  shares at more than one price must
complete  a  separate  letter  of  transmittal  for each  price  at  which  such
stockholder tenders shares,  provided that a stockholder may not tender the same
shares (unless  properly  withdrawn  previously in accordance with Section 4) at
more than one price. To tender shares properly,  stockholders must check one and
only one price box in the appropriate section of each letter of transmittal.  If
you check  more than one box or if you fail to check any box at all you will not
have validly tendered your shares.

     Odd lot holders who tender all of their  shares must  complete  the section
captioned  "Odd Lots" in the letter of transmittal  and, if  applicable,  in the
notice  of  guaranteed  delivery,  to  qualify  for the  preferential  treatment
available to odd lot holders as set forth in Section 1.

     We urge  stockholders  who hold shares through  brokers or banks to consult
the brokers or banks to determine  whether  transaction  costs are applicable if
they  tender  shares  through  the  brokers  or banks  and not  directly  to the
depositary.

     Signature Guarantees. Except as otherwise provided below, all signatures on
a letter of transmittal must be guaranteed by a financial institution (including
most banks,  savings and loans  associations  and  brokerage  houses) which is a
participant in an acceptable medallion guarantee program. Signatures on a letter
of transmittal need not be guaranteed if:

     -    the letter of transmittal  is signed by the  registered  holder of the
          shares (which term,  for purposes of this Section 3, shall include any
          participant  in  The  Depository  Trust  Company,  referred  to as the
          "book-entry  transfer  facility,"  whose  name  appears  on a security
          position  listing as the owner of the shares)  tendered  therewith and
          the  holder  has  not  completed  either  the box  captioned  "Special
          Delivery   Instructions"   or  the  box  captioned   "Special  Payment
          Instructions" in the letter of transmittal; or

     -    shares are tendered for the account of a bank, broker,  dealer, credit
          union,  savings  association or other entity which is a member in good
          standing  of an  acceptable  medallion  guarantee  program  or a bank,
          broker,  dealer,  credit union,  savings  association  or other entity
          which is an "eligible guarantor  institution," as such term is defined
          in Rule 17Ad-15  under the  Exchange  Act.  See  Instruction  1 of the
          letter of transmittal.

     If a share certificate is registered in the name of a person other than the
person  executing  a letter of  transmittal,  or if  payment  is to be made to a
person other than the registered  holder,  then the certificate must be endorsed
or accompanied by an appropriate  stock power,  in either case signed exactly as
the name of the registered holder appears on the certificate, with the signature
guaranteed by an eligible guarantor institution.

     D&PL will make payment for shares  tendered and accepted for payment  under
the tender offer only after the depositary timely receives share certificates or
a  timely  confirmation  of the  book-entry  transfer  of the  shares  into  the
depositary's  account at the book-entry  transfer facility as described above, a
properly  completed  and duly  executed  letter of  transmittal,  or an  agent's
message in the case of a book-entry  transfer,  and any other documents required
by the letter of transmittal.

                                       18


     Method of  Delivery.  The method of  delivery of all  documents,  including
share certificates,  the letter of transmittal and any other required documents,
is at the  election  and risk of the  tendering  stockholder.  If you  choose to
deliver  required  documents by mail, we recommend that you use registered  mail
with return receipt requested,  properly insured. In all cases,  sufficient time
should be allowed to ensure timely delivery.

     Book-Entry Delivery.  The depositary will establish an account with respect
to the  shares  for  purposes  of the tender  offer at the  book-entry  transfer
facility within two business days after the date of this offer to purchase,  and
any financial  institution  that is a  participant  in the  book-entry  transfer
facility's  system may make  book-entry  delivery  of the shares by causing  the
book-entry transfer facility to transfer shares into the depositary's account in
accordance  with the  book-entry  transfer  facility's  procedures for transfer.
Although participants in the book-entry transfer facility may effect delivery of
shares  through a  book-entry  transfer  into the  depositary's  account  at the
book-entry transfer facility, either:

     -    a  properly   completed  and  duly  executed  letter  of  transmittal,
          including any required signature guarantees,  or an agent's message in
          the case of a book-entry  transfer,  and any other required  documents
          must, in any case, be transmitted to and received by the depositary at
          its address set forth on the back cover page of this offer to purchase
          before the expiration date; or

     -    the guaranteed delivery procedure described below must be followed.

     Delivery of the letter of transmittal  and any other required  documents to
the book-entry transfer facility does not constitute delivery to the depositary.

     The term "agent's  message"  means a message  transmitted by the book-entry
transfer  facility to, and received  by, the  depositary,  which states that the
book-entry  transfer  facility has received an express  acknowledgment  from the
participant in the book-entry  transfer  facility  tendering the shares that the
participant  has  received  and agrees to be bound by the terms of the letter of
transmittal and that D&PL may enforce the agreement against the participant.

     Company Stock Option Plans. D&PL is not offering,  as part of the offer, to
purchase any of the options  outstanding  under the Company's stock option plans
and tenders of such options will not be accepted. In no event are any options to
be delivered to the depositary in connection with a tender of shares  hereunder.
An  exercise of an option  cannot be revoked  even if shares  received  upon the
exercise  thereof and  tendered in the offer are not  purchased in the offer for
any reason.

     Federal  Backup  Withholding  Tax.  Under the  federal  income  tax  backup
withholding  rules,  28% of the gross proceeds payable to a stockholder or other
payee  pursuant to the tender  offer must be withheld and remitted to the United
States  Treasury,  unless the  stockholder  or other payee  provides  his or her
taxpayer  identification  number  (employer   identification  number  or  social
security  number) to the depositary and certifies that such number is correct or
an exemption otherwise applies under applicable regulations.  Therefore,  unless
such  an  exemption  exists  and  is  proven  in a  manner  satisfactory  to the
depositary,  each tendering  stockholder should complete and sign the Substitute

                                       19


Form  W-9  included  with  the  letter  of  transmittal  so  as to  provide  the
information and  certification  necessary to avoid backup  withholding.  Certain
stockholders  (including,  among others,  all  corporations  and certain foreign
individuals)  are  not  subject  to  these  backup   withholding  and  reporting
requirements.  In  order  for a  foreign  individual  to  qualify  as an  exempt
recipient,  that stockholder must submit a statement,  signed under penalties of
perjury,  attesting to that individual's exempt status.  Tendering  stockholders
can obtain such statements from the depositary. See Instruction 13 of the letter
of transmittal.

     Any tendering  stockholder  or other payee who fails to complete  fully and
sign the  Substitute  Form W-9 included  with the letter of  transmittal  may be
subject to required  federal  income tax backup  withholding of 28% of the gross
proceeds paid to such stockholder or other payee pursuant to the tender offer.

     Gross  proceeds   payable  pursuant  to  the  tender  offer  to  a  foreign
stockholder or his or her agent will be subject to withholding of federal income
tax at a rate of 30%,  unless we determine that a reduced rate of withholding is
applicable  pursuant to a tax treaty or that an exemption  from  withholding  is
applicable  because  such gross  proceeds  are  effectively  connected  with the
conduct of a trade or business  within the United  States.  For this purpose,  a
foreign stockholder is any stockholder that is not:

     -    a citizen or resident of the United States,

     -    a corporation,  partnership or other entity created or organized in or
          under  the laws of the  United  States,  any  State  or any  political
          subdivision thereof,

     -    a trust whose  administration is subject to the primary supervision of
          a U.S.  court  and which  has one or more  U.S.  persons  who have the
          authority to make all substantial decisions, or

     -    an estate  the income of which is  subject  to United  States  federal
          income taxation regardless of its source.

     A foreign stockholder may be eligible to file for a refund of such tax or a
portion  of such  tax if such  stockholder  meets  the  "complete  termination,"
"substantially  disproportionate" or "not essentially  equivalent to a dividend"
tests  described in Section 14 or if such  stockholder  is entitled to a reduced
rate of withholding pursuant to a tax treaty and D&PL withheld at a higher rate.
In order to obtain a reduced rate of withholding  under a tax treaty,  a foreign
stockholder  must  deliver  to the  depositary  before  the  payment a  properly
completed  and executed  statement  claiming  such an  exemption  or  reduction.
Tendering stockholders can obtain such statements from the depositary.  In order
to claim an exemption  from  withholding on the grounds that gross proceeds paid
pursuant to the tender  offer are  effectively  connected  with the conduct of a
trade or business within the United States,  a foreign  stockholder must deliver
to the  depositary  a  properly  executed  statement  claiming  such  exemption.
Tendering  stockholders  can obtain such  statements  from the  depositary.  See
Instruction 13 of the letter of  transmittal.  We urge foreign  stockholders  to
consult their own tax advisors  regarding the  application of federal income tax
withholding,  including eligibility for a withholding tax reduction or exemption
and the refund procedure.

     For a  discussion  of United  States  federal  income tax  consequences  to
tendering stockholders, see Section 14.

                                       20


     Guaranteed  Delivery.  If a stockholder  desires to tender shares under the
tender  offer  and the  stockholder's  share  certificates  are not  immediately
available  or the  stockholder  cannot  deliver  the share  certificates  to the
depositary  before the expiration  date, or the stockholder  cannot complete the
procedure for book-entry  transfer on a timely basis, or if time will not permit
all required  documents to reach the depositary  before the expiration date, the
stockholder may  nevertheless  tender the shares,  provided that the stockholder
satisfies all of the following conditions:

     -    the stockholder  makes the tender by or through an eligible  guarantor
          institution;

     -    the depositary receives by hand, mail,  overnight courier or facsimile
          transmission,  before the  expiration  date, a properly  completed and
          duly  executed  notice  of  guaranteed  delivery  in the form D&PL has
          provided,  specifying the price at which the  stockholder is tendering
          shares,   including  (where  required)  a  guarantee  by  an  eligible
          guarantor  institution  in the  form  set  forth  in  such  notice  of
          guaranteed delivery; and

     -    the  depositary  receives the share  certificates,  in proper form for
          transfer,  or confirmation  of book-entry  transfer of the shares into
          the depositary's account at the book-entry transfer facility, together
          with a properly completed and duly executed letter of transmittal,  or
          a manually  signed  facsimile  thereof,  and  including  any  required
          signature  guarantees,  or an agent's message, and any other documents
          required by the letter of transmittal,  within three NYSE trading days
          after  the  date  of  receipt  by  the  depositary  of the  notice  of
          guaranteed delivery.

     Return of Unpurchased  Shares. The depositary will return  certificates for
unpurchased  shares  promptly  after the expiration or termination of the tender
offer or the proper withdrawal of the shares, as applicable,  or, in the case of
shares tendered by book-entry transfer at the book-entry transfer facility,  the
depositary will credit the shares to the appropriate  account  maintained by the
tendering  stockholder at the book-entry transfer facility, in each case without
expense to the stockholder.

     Determination  of  Validity;  Rejection  of Shares;  Waiver of Defects;  No
Obligation  to  Give  Notice  of  Defects.  D&PL  will  determine,  in its  sole
discretion,  all  questions as to the number of shares that we will accept,  the
price  that we will  pay for  shares  that we  accept  and the  validity,  form,
eligibility (including time of receipt) and acceptance for payment of any tender
of shares, and our determination will be final and binding on all parties.  D&PL
reserves the  absolute  right to reject any or all tenders of any shares that it
determines  are not in proper form or the  acceptance  for payment of or payment
for which D&PL determines may be unlawful. D&PL also reserves the absolute right
to waive any defect or irregularity in any tender with respect to any particular
shares or any particular stockholder,  and D&PL's interpretation of the terms of
the tender offer will be final and binding on all  parties.  No tender of shares
will be deemed to have been properly made until the  stockholder  cures, or D&PL
waives,  all  defects  or  irregularities.  None of D&PL,  the  depositary,  the
information agent, the dealer manager or any other person will be under any duty
to give notification of any defects or irregularities in any tender or incur any
liability for failure to give this notification.

                                       21


     Tendering  Stockholder's  Representation  and Warranty;  D&PL's  Acceptance
Constitutes  an  Agreement.  A tender  of  shares  under  any of the  procedures
described  above will constitute the tendering  stockholder's  acceptance of the
terms and conditions of the tender offer, as well as the tendering stockholder's
representation and warranty to D&PL that:

     -    the  stockholder  has a net long  position in the shares or equivalent
          securities at least equal to the shares tendered within the meaning of
          Rule 14e-4 of the Exchange Act; and

     -    the tender of shares complies with Rule 14e-4.

     It is a violation of Rule 14e-4 for a person,  directly or  indirectly,  to
tender shares for that person's own account unless, at the time of tender and at
the end of the  proration  period or period  during which shares are accepted by
lot (including any extensions  thereof),  the person so tendering has a net long
position equal to or greater than the amount tendered in:

     -    the shares; or

     -    securities   immediately   convertible   into,  or   exchangeable   or
          exercisable for, the shares; and

     -    will deliver or cause to be delivered  the shares in  accordance  with
          the terms of the tender offer.

     Rule  14e-4  provides  a similar  restriction  applicable  to the tender or
guarantee of a tender on behalf of another person. D&PL's acceptance for payment
of shares  tendered under the tender offer will  constitute a binding  agreement
between the tendering  stockholder and D&PL upon the terms and conditions of the
tender offer.

     Lost or Destroyed  Certificates.  Stockholders  whose share certificate for
part or all of their shares has been lost,  stolen,  misplaced or destroyed must
contact Illinois Stock Transfer Company, the depositary for this offer, at (800)
757-5755 or (312) 427-2953, for instructions as to obtaining a replacement share
certificate.  That  share  certificate  will then be  required  to be  submitted
together with the letter of transmittal  in order to receive  payment for shares
that are tendered and accepted for payment.  The  stockholder may have to post a
bond to secure  against  the risk that the share  certificate  may  subsequently
emerge.  We  urge  stockholders  to  contact  Illinois  Stock  Transfer  Company
immediately in order to permit timely processing of this documentation.

     Stockholders  must deliver  share  certificates,  together  with a properly
completed  and duly  executed  letter of  transmittal,  including  any signature
guarantees,  or an agent's  message,  and any other  required  documents  to the
depositary and not to D&PL, the information agent or the dealer manager. Neither
D&PL,  the  information  agent nor the  dealer  manager  will  forward  any such
documents to the depositary and delivery to D&PL, the  information  agent or the
dealer manager will not constitute a proper tender of shares.

                                       22


4.   Withdrawal Rights.

     Stockholders  may withdraw  shares  tendered  under the tender offer at any
time prior to the expiration date and, unless accepted by D&PL for payment after
the expiration date, may also be withdrawn at any time after 12:00 Midnight, New
York City time, on Wednesday, June 15, 2005.

     For a withdrawal  to be effective,  the  depositary  must timely  receive a
written or  facsimile  transmission  notice of  withdrawal  at the  depositary's
address  set forth on the back cover page of this  offer to  purchase.  Any such
notice of  withdrawal  must specify the name of the tendering  stockholder,  the
number of shares that the  stockholder  wishes to  withdraw  and the name of the
registered holder of the shares. If the share  certificates to be withdrawn have
been  delivered or otherwise  identified  to the  depositary,  then,  before the
release  of the  share  certificates,  the  serial  numbers  shown on the  share
certificates  must be submitted to the  depositary and the  signature(s)  on the
notice of withdrawal  must be guaranteed by an eligible  guarantor  institution,
unless the shares have been  tendered  for the account of an eligible  guarantor
institution.

     If a stockholder  has tendered  shares under the  procedure for  book-entry
transfer set forth in Section 3, any notice of withdrawal  also must specify the
name and the number of the  account at the  book-entry  transfer  facility to be
credited with the withdrawn shares and must otherwise comply with the book-entry
transfer facility's procedures. D&PL will determine all questions as to the form
and validity (including the time of receipt) of any notice of withdrawal, in its
sole discretion, and such determination will be final and binding. None of D&PL,
the depositary,  the information  agent,  the dealer manager or any other person
will be under any duty to give  notification of any defects or irregularities in
any  notice  of  withdrawal  or incur any  liability  for  failure  to give this
notification.

     A  stockholder  may not rescind a withdrawal  and D&PL will deem any shares
that a stockholder  properly withdraws not properly tendered for purposes of the
tender offer,  unless the stockholder  properly  re-tenders the withdrawn shares
before the  expiration  date by  following  one of the  procedures  described in
Section 3.

     If D&PL extends the tender  offer,  is delayed in its purchase of shares or
is unable to  purchase  shares  under the  tender  offer for any  reason,  then,
without  prejudice to D&PL's rights under the tender offer,  the depositary may,
subject  to  applicable  law,  retain  tendered  shares on  behalf of D&PL,  and
stockholders  may not  withdraw  these  shares  except to the  extent  tendering
stockholders are entitled to withdrawal rights pursuant to applicable law and as
described in this Section 4.

5.   Purchase of Shares and Payment of Purchase Price.

     Upon the terms and subject to the conditions of the tender offer,  promptly
following the expiration date, D&PL:

     -    will  determine  the  purchase  price it will pay for shares  properly
          tendered and not properly withdrawn before the expiration date, taking
          into account the number of shares so tendered and the prices specified
          by tendering stockholders; and

                                       23


     -    will  accept for  payment and pay for,  and  thereby  purchase,  up to
          1,739,130  shares (or such greater number of shares as we may elect to
          purchase, subject to applicable law) properly tendered at prices at or
          below the  purchase  price  and not  properly  withdrawn  prior to the
          expiration date.

     For purposes of the tender offer,  D&PL will be deemed to have accepted for
payment, and therefore purchased,  shares that are properly tendered at or below
the purchase price determined by D&PL and not properly withdrawn, subject to the
"odd lot," proration and conditional tender provisions of the tender offer, only
when,  as and if it  gives  oral or  written  notice  to the  depositary  of its
acceptance of the shares for payment pursuant to the tender offer.

     Upon the terms and subject to the conditions of the tender offer,  promptly
after the  expiration  date,  D&PL will  accept for payment and pay a single per
share  purchase price not greater than $28.75 nor less than $25.00 per share for
1,739,130 shares,  subject to increase or decrease as provided in Section 15, if
properly tendered and not properly withdrawn,  or such fewer number of shares as
are properly tendered and not properly withdrawn.

     D&PL will pay for shares that it purchases  pursuant to the tender offer by
depositing the aggregate  purchase  price for these shares with the  depositary,
which will act as agent for tendering  stockholders for the purpose of receiving
payment from D&PL and transmitting payment to the tendering stockholders.

     In the event of proration, D&PL will determine the proration factor and pay
for those tendered shares accepted for payment as soon as practicable  after the
expiration date; however,  D&PL does not expect to be able to announce the final
results of any  proration  and commence  payment for shares  purchased  until at
least five business days after the expiration date. Under no circumstances  will
D&PL pay interest on the purchase  price  regardless  of any delay in making the
payment.  Shares  tendered and not purchased,  including all shares  tendered at
prices  greater than the purchase price and shares that D&PL does not accept for
purchase  due to  proration  or  conditional  tenders,  will be  returned to the
tendering  stockholder,  or,  in the  case  of  shares  tendered  by  book-entry
transfer,  will be  credited  to the  account  maintained  with  the  book-entry
transfer  facility by the  participant  therein who so delivered the shares,  at
D&PL's expense,  promptly after the expiration date or termination of the tender
offer without  expense to the tendering  stockholders.  If certain events occur,
D&PL may not be obligated to purchase shares  pursuant to the tender offer.  See
Section 7. D&PL will issue a press release  announcing the price it will pay for
shares tendered in the offer promptly following the expiration date.

     D&PL will pay all stock transfer taxes, if any,  payable on the transfer to
it of shares purchased under the tender offer. If, however,

     -    payment of the  purchase  price is to be made to any person other than
          the registered holder;

     -    certificate(s)  for shares not tendered or tendered but not  purchased
          are to be  returned  in the name of and to any  person  other than the
          registered holder(s) of such shares; or

     -    if  tendered  certificates  are  registered  in the name of any person
          other than the person signing the letter of transmittal;

                                       24


the  amount  of all  stock  transfer  taxes,  if  any  (whether  imposed  on the
registered  holder or the other  person),  payable on account of the transfer to
the person will be deducted from the purchase price unless satisfactory evidence
of the  payment  of  the  stock  transfer  taxes,  or  exemption  therefrom,  is
submitted. See Instruction 10 of the letter of transmittal.

     Any tendering  stockholder or other payee who fails to complete fully, sign
and return to the depositary the Substitute Form W-9 included with the letter of
transmittal may be subject to U.S. federal income tax backup  withholding on the
gross  proceeds paid to the  stockholder  or other payee under the tender offer.
See Section 3.

6.   Conditional Tender of Shares.

     Subject  to the  exception  for  holders  of odd  lots,  in the event of an
over-subscription  of the tender offer, shares tendered at or below the purchase
price prior to the expiration date will be subject to proration.  See Section 1.
As  discussed  in  Section  14,  the  number of shares  to be  purchased  from a
particular  stockholder  may affect the tax  treatment  of the  purchase  to the
stockholder and the  stockholder's  decision whether to tender.  Accordingly,  a
stockholder may tender shares subject to the condition that D&PL must purchase a
specified  minimum number of the  stockholder's  shares  tendered  pursuant to a
letter of  transmittal if D&PL purchases any shares  tendered.  Any  stockholder
desiring to make a  conditional  tender  must so  indicate  in the box  entitled
"Conditional  Tender" in the letter of transmittal  and, if  applicable,  in the
notice of guaranteed  delivery,  and indicate the minimum  number of shares that
D&PL must purchase if D&PL  purchases any shares.  We urge each  stockholder  to
consult with his or her own financial or tax advisors.

     After the expiration  date, if more than 1,739,130  shares (or such greater
number of shares as we may elect to  purchase,  subject to  applicable  law) are
properly  tendered  and not  properly  withdrawn,  so that we must  prorate  our
acceptance of and payment for tendered  shares,  we will calculate a preliminary
proration  percentage based upon all shares properly tendered,  conditionally or
unconditionally.  If the effect of this preliminary proration would be to reduce
the number of shares that we  purchase  from any  stockholder  below the minimum
number  specified,  the shares  conditionally  tendered  will  automatically  be
regarded as  withdrawn  (except as provided in the next  paragraph).  All shares
tendered by a stockholder  subject to a conditional tender that are withdrawn as
a  result  of  proration  will  be  returned  at our  expense  to the  tendering
stockholder.

     After  giving  effect to these  withdrawals,  we will accept the  remaining
shares properly tendered, conditionally or unconditionally, on a pro rata basis,
if  necessary.  If  conditional  tenders  that would  otherwise  be  regarded as
withdrawn  would cause the total number of shares that we purchase to fall below
1,739,130 (or such greater number of shares as we may elect to purchase, subject
to applicable  law) then, to the extent  feasible,  we will select enough of the
shares conditionally tendered that would otherwise have been withdrawn to permit
us to  purchase  such  number of  shares.  In  selecting  among the  conditional
tenders,  we will select by random  lot,  treating  all tenders by a  particular
taxpayer  as a single  lot,  and will  limit  our  purchase  in each case to the
designated minimum number of shares to be purchased. To be eligible for purchase
by random lot,  stockholders  whose shares are conditionally  tendered must have
tendered all of their shares.

                                       25


7.   Conditions of the Tender Offer.

     Notwithstanding  any other  provision of the tender  offer,  we will not be
required to accept for payment, purchase or pay for any shares tendered, and may
terminate or amend the tender offer or may postpone the  acceptance  for payment
of, or the  purchase  of and the payment  for shares  tendered,  subject to Rule
13e-4(f)  under the Exchange Act, if, at any time on or after April 20, 2005 and
before the  expiration  of the offer,  any of the  following  events  shall have
occurred (or shall have been reasonably determined by us to have occurred) that,
in our reasonable  judgment and regardless of the  circumstances  giving rise to
the event or events,  make it  inadvisable  to proceed  with the tender offer or
with acceptance for payment:

     -    there shall have been  instituted  or be pending or the Company  shall
          have received  notice of any action or proceeding by any government or
          governmental,   regulatory  or  administrative  agency,  authority  or
          tribunal or any other person,  domestic or foreign,  before any court,
          authority, agency or tribunal that:

          -    challenges  the making of the tender offer,  the  acquisition  of
               some or all of the  shares  under the tender  offer or  otherwise
               relates in any manner to the tender offer; or

          -    in our reasonable judgment, could materially and adversely affect
               the business, condition (financial or otherwise), assets, income,
               operations or prospects of us or any of our  subsidiaries,  taken
               as a whole, or otherwise materially impair in any way the conduct
               of the business of us or any of our  subsidiaries  or  materially
               impair our ability to achieve the purposes of the tender offer;

     -    there  shall  have been any  action  pending  or taken or of which the
          Company  shall have  received  notice,  or approval  withheld,  or any
          statute,  rule,  regulation,  judgment,  order or injunction proposed,
          sought, promulgated,  enacted, entered, amended, enforced or deemed to
          be applicable to the tender offer or us or any of our subsidiaries, by
          any court or any authority, agency or tribunal that, in our reasonable
          judgment, would:

          -    make the  acceptance  for payment of, or payment for, some or all
               of  the  shares   illegal  or  otherwise   restrict  or  prohibit
               completion of the tender offer;

          -    delay or  restrict  the  ability of us, or render us  unable,  to
               accept for payment or pay for some or all of the shares;

          -    materially  impair our  ability to achieve  the  purposes  of the
               tender offer; or

          -    materially   and  adversely   affect  the   business,   condition
               (financial or otherwise), assets, income, operations or prospects
               of us  or  our  subsidiaries,  taken  as a  whole,  or  otherwise
               materially impair the conduct of the business of us or any of our
               subsidiaries;

                                       26


     -    there shall have occurred:

          -    any general  suspension  of trading in, or  limitation  on prices
               for,  securities  on any national  securities  exchange or in the
               over-the-counter  market in the  United  States  or the  European
               Union;

          -    the  declaration  of a banking  moratorium  or any  suspension of
               payments in respect of banks in the United States or the European
               Union;

          -    a material change in United States or any other currency exchange
               rates or a suspension of or limitation on the markets therefor;

          -    the  commencement  or escalation of a war,  armed  hostilities or
               other  international or national  calamity directly or indirectly
               involving the United States or any of its territories,  including
               but not limited to an act of terrorism;

          -    any limitation  (whether or not  mandatory) by any  governmental,
               regulatory  or  administrative  agency  or  authority  on, or any
               event,  or any  disruption or adverse  change in the financial or
               capital markets  generally or the market for loan syndications in
               particular,  that, in our reasonable  judgment,  would affect the
               extension of credit by banks or other lending institutions in the
               United States;

          -    any  change  in  the  general  political,   market,  economic  or
               financial  conditions  in the United States or abroad that could,
               in our reasonable judgment, have a material adverse effect on the
               business,  condition  (financial or otherwise),  assets,  income,
               operations  or  prospects of us or our  subsidiaries,  taken as a
               whole, or otherwise  materially  impair in any way the conduct of
               the business of us or any of our subsidiaries;

          -    in the case of any of the  foregoing  existing at the time of the
               commencement  of the tender  offer,  a material  acceleration  or
               worsening thereof; or

          -    any  decline in the  market  price of the shares or the Dow Jones
               Industrial  Average  or the  Standard  and  Poor's  Index  of 500
               Industrial Companies or the New York Stock Exchange or the Nasdaq
               Composite  Index  by  a  material  amount   (including,   without
               limitation,  an  amount  greater  than  10%)  from  the  close of
               business on April 20, 2005;

     -    a tender offer or exchange  offer for any or all of the shares  (other
          than this tender offer), or any merger,  business combination or other
          similar transaction with or involving us or any of our subsidiaries or
          affiliates, shall have been proposed, announced or made by any person;

     -    any of the following shall have occurred:

          -    any  "group"  (as that term is used in  Section  13(d)(3)  of the
               Exchange  Act)  shall  have been  formed  that  shall own or have
               acquired  or proposed  to  acquire,  or any entity or  individual
               shall have acquired or proposed to acquire,  beneficial ownership
               of more than 5% of the outstanding shares;

                                       27


          -    any  entity,  group or  person  who has filed a  Schedule  13D or
               Schedule 13G with the  Securities  and Exchange  Commission on or
               before the  commencement of this tender offer shall have acquired
               or proposed to acquire  beneficial  ownership of an additional 2%
               or more of the outstanding shares; or

          -    any person,  entity or group shall have filed a Notification  and
               Report Form under the  Hart-Scott-Rodino  Antitrust  Improvements
               Act of 1976, as amended, or made a public announcement reflecting
               an intent to acquire us or any of our  subsidiaries or any of our
               or their respective assets or securities;

     -    any change or  combination  of changes shall have  occurred,  or as to
          which we have received notice, in the business,  condition  (financial
          or  otherwise),   assets,  income,  operations,   prospects  or  stock
          ownership of us or any of our subsidiaries,  taken as a whole, that in
          our judgment is reasonably  likely to be material and adverse to us or
          any of our  subsidiaries  or that  otherwise  materially  impairs  the
          conduct of the business of us or any of our subsidiaries;

     -    any approval,  permit,  authorization,  favorable review or consent of
          any governmental entity required to be obtained in connection with the
          tender offer shall not have been obtained on terms  satisfactory to us
          in our reasonable judgment; or

     -    we reasonably  determine  that the  completion of the tender offer and
          the purchase of the shares may:

          -    cause the shares to be held of record by fewer than 300  persons;
               or

          -    cause the shares to be  delisted  from the NYSE or to be eligible

     The foregoing  conditions  are for our the sole benefit and may be asserted
by us regardless of the  circumstances  giving rise to any of these  conditions,
and may be waived by us, in whole or in part, at any time and from time to time,
before the expiration of the offer, in our sole  discretion.  Our failure at any
time to exercise any of the foregoing rights shall not be deemed a waiver of any
of these rights,  and each of these rights shall be deemed an ongoing right that
may be asserted at any time and from time to time before the  expiration  of the
offer. Any determination or judgment by us concerning the events described above
will be final and binding on all parties.

8.   Price Range of Shares; Dividends.

     Our common stock is listed and traded on the NYSE under the trading  symbol

     Fourth Quarter                                          $25.30           $21.78            $0.10

     Stockholders of Record.  As of April 14, 2005,  there were 272 stockholders
of record of our common  stock,  as  furnished by our stock  transfer  agent and
registrar,  Illinois Stock Transfer Company.  Several brokerage firms, banks and
other  institutions  ("nominees")  are listed once on the stockholders of record
listing.  However, in most cases, the nominees' holdings represent blocks of our
stock held in brokerage  accounts  for a number of  stockholders.  As such,  our
actual number of stockholders  is difficult to estimate with  precision,  but we
estimate we have approximately 20,000 stockholders.

     Dividends. Our dividend policy is determined at the discretion of our Board
of Directors.  While we currently  anticipate that quarterly cash dividends will
continue to be paid in the future, there can be no assurance that payment of the
dividend will  continue.  Our ability to pay any cash  dividends on our stock is
dependent on our earnings and cash requirements.

     Recent  Market Price.  We publicly  announced the tender offer on April 20,
2005,  before the open of trading on the NYSE on that date.  On April 15,  2005,
the last trading day prior to printing of the tender offer, the reported closing
price per share of our common stock on the NYSE was $25.68. We urge stockholders
to obtain current market quotations for the common stock.

                                       29


9.   Source and Amount of Funds.

     Assuming  that  1,739,130  shares of our common stock are  purchased in the
tender  offer,  at a price  between  $25.00 and $28.75 per share,  the aggregate
purchase price will be between approximately $43.5 million and $50.0 million. We
anticipate  that we will fund the  purchase of the shares  tendered in the offer
through cash on hand.

10.  Certain Information Concerning D&PL.

     General.   D&PL  is  primarily   engaged  in  the   breeding,   production,
conditioning  and marketing of proprietary  varieties of cotton planting seed in
the United States and other cotton producing  nations.  We also breed,  produce,
condition and market soybean planting seed in the United States.

     Since 1915, we have bred,  produced and/or marketed upland picker varieties
of cotton  planting seed for cotton  varieties that are grown  primarily east of
Texas  and in  Arizona.  We have used our  extensive  classical  plant  breeding
programs to develop a gene pool  necessary for producing  cotton  varieties with
improved  agronomic  traits  important  to farmers  (such as crop  yield) and to
textile manufacturers (such as enhanced fiber characteristics).

     In 1980,  we added  soybean seed to our product line. In 1996, we commenced
commercial  sales in the  United  States  of  cotton  planting  seed  containing
Bollgard gene technology  licensed from Monsanto which expresses a protein toxic
to certain  lepidopteran  pests. Since 1997, we have marketed in the U.S. cotton
planting seed that contains a gene that provides  tolerance to  glyphosate-based
herbicides,  commonly referred to as Roundup Ready cotton. In 1997, we commenced
commercial  sales in the U.S. of soybean planting seed that contains a gene that
provides tolerance to glyphosate-based herbicides ("Roundup Ready Soybeans"). In
1998, we commenced  sales of cotton  planting seed of varieties  containing both
the Bollgard and Roundup Ready genes.

     During the 1980's,  as a component of our  long-term  growth  strategy,  we
began to market our  products,  primarily  cottonseed,  internationally.  Over a
period of years, we have  strengthened and expanded our  international  staff in
order to support our expanding  international  business.  In foreign  countries,
cotton  acreage  is often  planted  with  farmer-saved  seed  which has not been
delinted or treated and is of low overall  quality.  We believe  that we have an
attractive  opportunity  to  penetrate  foreign  markets  because  of our widely
adaptable,  superior cotton varieties,  technological  know-how in producing and
conditioning  high-quality  seed and our brand  name  recognition.  Furthermore,
Monsanto's  Bollgard and Roundup  Ready gene  technologies  (that we either have
licensed or have options to license) are  effective in many  countries and could
bring value to farmers.

     We sell our  products  in foreign  countries  through  (i) export  sales to
distributors and (ii) direct in-country operations through either joint ventures
or wholly-owned  subsidiaries.  The method varies and evolves,  depending on our
assessment of the potential size and  profitability of the market,  governmental
policies,  currency and credit  risks,  sophistication  of the target  country's
agricultural  economy,  and costs (as compared to risks) of commencing  physical

                                       30


operations in a particular country. In 2004, the majority of international sales
came from direct in-country operations (primarily Argentina,  Australia, Brazil,
China, South Africa and Turkey).

     We currently  have three plans  pursuant to which equity awards are granted
and issued:  the 1993 Stock Option Plan (the "1993  Plan"),  the 1995  Long-Term
Incentive  Plan (the  "1995  Plan") and the 2005  Omnibus  Stock Plan (the "2005
Plan").

     In 1993,  the  Company  adopted  the 1993 Plan,  but no more  options  were
granted under this plan  effective  with the adoption of the 1995 Plan. In 1995,
the Company's Board of Directors  adopted the 1995 Plan that was ratified by the
stockholders at the 1996 Annual Meeting.  In 2000, the 1995 Plan was amended and
restated  eliminating  the  ability  of our Board of  Directors  to award  stock
appreciation  rights,  restricted  shares of common stock and  performance  unit
credits.  Pursuant to the amended and restated 1995 Plan, the Board of Directors
may award stock  options to officers,  key employees  and  directors.  Under the
amended and restated 1995 Plan, 5,120,000 shares are authorized for grant, which
is an increase from the original 2,560,000 shares. As of April 13, 2005, options
for 5,310,359  shares have been granted under the 1995 Plan, of which  1,308,492
have been forfeited, leaving available for grant 1,118,133 shares.

     Under the 1993 Plan, all stock options  granted vested at a rate of 20% per
annum  commencing  on the  first  day of the  second  and each  succeeding  year
following each grant and expire ten years from the date of the grant. The number
of shares  available  for grant  under  the 1993  Plan and upon  forfeitures  of
options  outstanding  thereunder has been reduced to zero, and no further option
grants are being made under this plan.

     Stock options granted under the 1995 Plan vest in accordance with an option
agreement  that  contains  the terms and  conditions  applicable  to each option
grant.  No option  shall be  exercisable  after  ten years  from the date of the
grant.  Shares  subject to options and awards  under the 1995 Plan which  expire
unexercised are available for new option grants and awards.

     The 2005 Plan was approved at our Annual Meeting of Stockholders in January
2005.  The  2005  Plan  provides  for the  grant  of  incentive  stock  options,
non-qualified stock options, restricted stock and restricted stock units to D&PL
employees,  independent contractors and members of the Board of Directors at the
discretion of the Compensation  Committee of the Board. Such a grant, subject to
the terms and provisions of the 2005 Plan, is in such number and upon such terms
as determined by the Compensation Committee.

     Up to 4,500,000  shares are  available  for grants under the 2005 Plan.  No
shares  under the 2005 Plan have yet been  issued.  Also,  the shares  available
under the 2005 Plan are in addition to the shares available under the 1995 Plan.
The maximum number of shares which may be issued for awards of restricted  stock
and  restricted  stock units is 2,100,000  shares.  The maximum number of shares
with  respect to which  shares or  restricted  stock,  restricted  stock  units,
options or a combination thereof may be granted during any year to any person is
250,000 shares.

     Except as otherwise  described  in this Offer to Purchase,  none of D&PL or
any  person  controlling  us or,  to our  knowledge,  any  of our  directors  or
executive officers,  is a party to any contract,  arrangement,  understanding or
relationship  with any other person  relating,  directly or  indirectly,  to our
offer or with respect to any of our securities,  including,  but not limited to,
any contract, arrangement, understanding or relationship concerning the transfer

                                       35


or  the  voting  of  any  such  securities,   joint  ventures,  loan  or  option
arrangements, puts or calls, guarantees of loans, guarantees against loss or the
giving or withholding of proxies, consents or authorizations.

12.  Effects of the Tender Offer on the Market for Shares; Registration under
     the Exchange Act.

     The purchase by D&PL of shares  pursuant to the tender offer may reduce the
number of shares of common stock that might otherwise be traded publicly and may
reduce the number of D&PL  stockholders.  These reductions may reduce the volume
of trading in our shares of common  stock and may result in lower  stock  prices
and reduced  liquidity  in the trading of our shares of common  stock  following
completion of the tender offer.  Stockholders  may be able to sell  non-tendered
shares of common  stock in the future on the NYSE or  otherwise,  at a net price
higher or lower  than the  purchase  price in the tender  offer.  We can give no
assurance,  however,  as to the price at which a stockholder may be able to sell
such shares in the future.

     As of April 13, 2005, D&PL had 38,479,224 shares outstanding (not including
2,344,166  shares held in treasury and  8,307,403  shares  reserved for issuance
under various  equity  compensation  plans).  The  1,739,130  shares that we are
offering to purchase pursuant to the tender offer represent  approximately  4.5%
of the shares of common stock outstanding as of that date (or approximately 4.2%
of the shares on a diluted basis, assuming the exercise of all outstanding stock
options). Of the reserved shares, 2,689,270 shares are issuable upon exercise of
outstanding  stock  options.  Additionally,  1,066,667  shares  of our  Series M
Convertible Non-Voting Preferred Stock are outstanding as of April 13, 2005. The
Series M Convertible  Non-Voting  Preferred  Stock is  convertible  to shares of
common stock on a one-for-one basis.

     D&PL anticipates that there will be a sufficient number of shares of common
stock  outstanding and publicly traded following  completion of the tender offer
to ensure a  continued  trading  market for such  shares.  Based upon  published
guidelines  of the  NYSE,  D&PL does not  believe  that its  purchase  of shares
pursuant to the tender offer will cause the remaining outstanding shares of D&PL
common stock to be delisted from the NYSE.

     Our  shares  are  "margin  securities"  under  the  rules  of the  Board of
Governors of the Federal Reserve  System.  This  classification  has the effect,
among other  things,  of allowing  brokers to extend  credit to their  customers
using the shares as collateral.  D&PL believes  that,  following the purchase of
shares  pursuant  to the  tender  offer,  the shares of common  stock  remaining
outstanding  will continue to be margin  securities  for purposes of the Federal
Reserve Board's margin rules and regulations.

     Our common stock is  registered  under the Exchange  Act,  which  requires,
among other things,  that D&PL furnish certain  information to its  stockholders
and the  Securities  and Exchange  Commission and comply with the Securities and
Exchange  Commission's  proxy  rules in  connection  with  meetings  of the D&PL
stockholders.  D&PL believes that its purchase of shares  pursuant to the tender
offer will not result in the common stock becoming  eligible for  deregistration
under the Exchange Act.

                                       36


13.  Legal Matters; Regulatory Approvals.

     D&PL is not aware of any  license  or  regulatory  permit  material  to its
business  that  might be  adversely  affected  by its  acquisition  of shares as
contemplated  by the  tender  offer or of any  approval  or other  action by any
government or governmental,  administrative  or regulatory  authority or agency,
domestic,  foreign or supranational,  that would be required for the acquisition
of shares by D&PL as  contemplated  by the tender offer.  Should any approval or
other action be required,  D&PL  presently  contemplates  that it will seek that
approval or other action.  D&PL is unable to predict whether it will be required
to delay the acceptance for payment of or payment for shares  tendered under the
tender offer  pending the outcome of any such matter.  There can be no assurance
that any  approval  or other  action,  if needed,  would be obtained or would be
obtained  without  substantial  cost or conditions or that the failure to obtain
the  approval or other action  might not result in adverse  consequences  to its
business and financial condition. The obligations of D&PL under the tender offer
to accept for payment and pay for shares is subject to  conditions.  See Section
7.

14.  U.S. Federal Income Tax Consequences.

     The following  describes  the material  United  States  federal  income tax
consequences  relevant to the tender  offer.  This  discussion is based upon the
Internal  Revenue  Code of 1986,  as amended to the date  hereof  (the  "Code"),
existing and proposed Treasury  Regulations,  administrative  pronouncements and
judicial   decisions,   changes  to  which  could  materially   affect  the  tax
consequences described herein and could be made on a retroactive basis.

     This discussion  deals only with shares held as capital assets and does not
deal with all tax consequences that may be relevant to all categories of holders
(such as financial institutions,  dealers in securities or commodities,  traders
in  securities  who  elect  to  apply a  mark-to-market  method  of  accounting,
insurance companies,  tax-exempt organizations,  former citizens or residents of
the  United  States or  persons  who hold  shares as part of a hedge,  straddle,
constructive sale or conversion transaction). In particular, different rules may
apply to shares  received  through the  exercise of  employee  stock  options or
otherwise as compensation.  This discussion does not address the state, local or
foreign tax consequences of participating in the tender offer. Holders of shares
should consult their tax advisors as to the particular  consequences  to them of
participation in the tender offer.

     As used herein,  a "Holder"  means a beneficial  holder of shares that is a
citizen or resident of the United  States,  a corporation or entity taxable as a
corporation  created or organized  in or under the laws of the United  States or
any State  thereof,  a trust  whose  administration  is subject  to the  primary
supervision of a U.S. court and which has one or more U.S.  persons who have the
authority to make all substantial decisions, or an estate the income of which is
subject to United States federal income taxation regardless of its source.

     Holders   of  shares   who  are  not  United   States   holders   ("foreign
stockholders")  should  consult  their tax advisors  regarding the United States
federal income tax consequences  and any applicable  foreign tax consequences of
the  tender  offer  and  should  also  see  Section  3 for a  discussion  of the
applicable  United  States  withholding  rules and the potential for obtaining a
refund of all or a portion of any tax withheld.

                                       37


     If a  partnership  holds  shares,  the  tax  treatment  of a  partner  will
generally  depend  upon the  status of the  partner  and the  activities  of the
partnership.  Partners of  partnerships  holding shares should consult their tax
advisors.

     We urge  stockholders  to  consult  their tax  advisors  to  determine  the
particular tax consequences to them of participating in the tender offer.

     Non-Participation  in  the  Tender  Offer.  Holders  of  shares  who do not
participate  in the tender offer will not incur any tax liability as a result of
the consummation of the tender offer.

     Exchange of Shares  Pursuant to the Tender Offer. An exchange of shares for
cash  pursuant  to the  tender  offer will be a taxable  transaction  for United
States  federal  income tax purposes.  A Holder who  participates  in the tender
offer will,  depending on such  Holder's  particular  circumstances,  be treated
either as  recognizing  gain or loss from the  disposition  of the  shares or as
receiving a distribution from us with respect to our stock.

     Under Section 302 of the Code, a Holder will  recognize  gain or loss on an
exchange of shares for cash if the exchange:

     -    results  in a  "complete  termination"  of all  such  Holder's  equity
          interest in us;

     -    results in a "substantially  disproportionate" redemption with respect
          to such Holder; or

     -    is "not  essentially  equivalent  to a dividend"  with respect to such
          Holder.

     In applying  the Section  302 tests,  a Holder must take  account of shares
that such Holder  constructively owns under attribution rules, pursuant to which
the Holder  will be treated as owning  shares  owned by certain  family  members
(except that in the case of a "complete termination" a Holder may, under certain
circumstances,  waive  attribution from family members) and related entities and
shares that the Holder has the right to acquire by exercise of an option.

     An  exchange  of shares for cash will be a  substantially  disproportionate
redemption  with respect to a Holder if (A) the  percentage  of our  outstanding
voting  stock  that the  Holder  actually  and  constructively  owns  after  the
redemption  (treating as not  outstanding  all stock purchased by us pursuant to
the tender offer) is less than 80% of the percentage of our  outstanding  voting
stock  that the  Holder  owned  immediately  before the  exchange  (treating  as
outstanding  all stock  purchased by us pursuant to the tender  offer),  (B) the
percentage  of our  outstanding  common  stock  that  the  Holder  actually  and
constructively owns after the redemption  (treating as not outstanding all stock
purchased by us pursuant to the tender offer) is less than 80% of the percentage
of our  outstanding  common stock that the Holder owned  immediately  before the
exchange  (treating  as  outstanding  all stock  purchased by us pursuant to the
tender  offer),  and (C) the Holder  owns after the  redemption  less than fifty
percent of the total voting power of all classes of our stock  entitled to vote.
Holders should consult their tax advisors regarding the application of the rules
of Section 302 in their particular circumstances.

                                       38


     If an  exchange  of shares  for cash fails to  satisfy  the  "substantially
disproportionate"  test, the Holder may nonetheless satisfy the "not essentially
equivalent to a dividend"  test. An exchange of shares for cash will satisfy the
"not  essentially  equivalent to a dividend" test if it results in a "meaningful
reduction" of the Holder's equity  interest in us. The Internal  Revenue Service
has  indicated  in a  published  ruling  that  even  a  small  reduction  in the
proportionate  interest  of a small  minority  stockholder  in a  publicly  held
corporation who exercises no control over corporate  affairs may constitute such
a "meaningful  reduction." Under this ruling, it is likely that a small minority
stockholder  who exercises no control over D&PL,  and all of whose  actually and
constructively  owned shares are tendered at or below the purchase price,  would
satisfy the "not  essentially  equivalent  to a dividend"  test  notwithstanding
proration  in the tender  offer.  If you expect to rely on the "not  essentially
equivalent to a dividend"  test,  you should  consult your own tax advisor as to
its application in your particular situation.

     Holders  should  be  aware  that  it is  possible  that an  acquisition  or
disposition of shares by a Holder substantially contemporaneously with the offer
will be taken  into  account  in  determining  whether  any of the  three  tests
described  above is satisfied.  Holders  should consult their tax advisors as to
any effect of such an event on the application of these tests.

     If a Holder is treated as recognizing  gain or loss from the disposition of
the shares for cash,  such gain or loss will be equal to the difference  between
the amount of cash received and such Holder's tax basis in the shares  exchanged
therefor.  Any  such  gain or loss  will be  capital  gain or loss  and  will be
long-term  capital gain or loss if the holding  period of the shares exceeds one
year as of the date of the  exchange.  Calculation  of gain or loss must be made
separately  for each block of shares  owned by a Holder.  Under the tax laws,  a
Holder may be able to designate  which blocks and the order of such blocks to be
tendered  pursuant to the tender offer.  If no  designation  is made, the shares
earliest  acquired by the Holder will be  considered  redeemed  for  purposes of
determining basis and holding period.

     If a Holder is not treated under the Section 302 tests as recognizing  gain
or loss on an exchange of shares for cash, the entire amount of cash received by
such Holder pursuant to the exchange will be treated as a dividend to the extent
of the Holder's  allocable  portion of our current and accumulated  earnings and
profits and then as a return of capital to the extent of the  Holder's  basis in
the shares  exchanged and thereafter as capital gain.  Provided  certain holding
period  requirements  are  satisfied,  non-corporate  Holders  generally will be
subject to U.S.  federal income tax at a maximum rate of 15% on amounts  treated
as  dividends.  Such a  dividend  will be taxed at a maximum  rate of 15% in its
entirety,  without reduction for the tax basis of the shares  exchanged.  To the
extent that a purchase of a  non-corporate  Holder's  shares by us in the tender
offer is treated as the receipt by the Holder of a dividend,  the  non-corporate
Holder's  remaining  adjusted basis (reduced by the amount, if any, treated as a
return of capital) in the purchased  shares will be added to any shares retained
by the  Holder.  To the extent  that cash  received  in  exchange  for shares is
treated as a dividend  to a  corporate  Holder,  (i) it will be  eligible  for a
dividends-received deduction (subject to applicable limitations) and (ii) it may
be  subject  to the  "extraordinary  dividend"  provisions  of the Code.  If the
extraordinary  dividend provisions are applicable,  the corporate Holder's basis
in the  purchased  shares may be reduced  (but not below zero) by the  non-taxed

                                       39


portion  of the  dividend  before  adding  such basis to the basis of the shares
retained by the Holder, and if the non-taxed portion of the dividend exceeds the
basis,  the corporate  Holder may  recognize  gain in the amount of such excess.
Corporate Holders should consult their tax advisors  concerning the availability
of the  dividends-received  deduction and the application of the  "extraordinary
dividend" provisions of the Code in their particular circumstances.

     We cannot  predict  whether or the extent to which the tender offer will be
oversubscribed.  If the tender  offer is  oversubscribed,  proration  of tenders
pursuant  to the  tender  offer will cause us to accept  fewer  shares  than are
tendered. Therefore, a Holder can be given no assurance that a sufficient number
of such Holder's shares will be purchased pursuant to the tender offer to ensure
that such  purchase  will be treated  as a sale or  exchange,  rather  than as a
dividend, for federal income tax purposes pursuant to the rules discussed above.
However,  see Section 6 regarding a Holder's  right to tender shares  subject to
the  condition  that D&PL  must  purchase  a  specified  minimum  number of such
Holder's shares (if any are to be purchased).

     See  Section 3 with  respect  to the  application  of  federal  income  tax
withholding and backup withholding.

     We urge  stockholders  to  consult  their  tax  advisor  to  determine  the
particular  tax  consequences  to  them  of  the  tender  offer,  including  the
applicability and effect of state, local and foreign tax laws.

15.  Extension of the Tender Offer; Termination; Amendment.

     D&PL expressly reserves the right, in its sole discretion,  at any time and
from time to time,  and regardless of whether or not any of the events set forth
in Section 7 shall have occurred or shall be deemed by D&PL to have occurred, to
extend the period of time  during  which the  tender  offer is open and  thereby
delay  acceptance  for payment of, and payment for, any shares by giving oral or
written  notice  of  the  extension  to  the  depositary  and  making  a  public
announcement  of the extension.  D&PL also expressly  reserves the right, in its
sole discretion, to terminate the tender offer and not accept for payment or pay
for any shares not  theretofore  accepted for payment or paid for or, subject to
applicable law, to postpone payment for shares upon the occurrence of any of the
conditions  specified  in  Section  7  by  giving  oral  or  written  notice  of
termination or postponement  to the depositary and making a public  announcement
of the  termination or  postponement.  D&PL's  reservation of the right to delay
payment  for  shares  that  it has  accepted  for  payment  is  limited  by Rule
13e-4(f)(5)  promulgated  under the Exchange Act,  which requires that D&PL must
pay the  consideration  offered  or return the shares  tendered  promptly  after
termination  or  withdrawal  of a  tender  offer.  Subject  to  compliance  with
applicable  law, D&PL further  reserves the right, in its sole  discretion,  and
regardless  of  whether  any of the  events  set forth in  Section 7 shall  have
occurred or shall be deemed by D&PL to have occurred,  to amend the tender offer
in any respect,  including,  without limitation, by decreasing or increasing the
consideration  offered in the tender offer to holders of shares or by decreasing
or increasing the number of shares being sought in the tender offer.  Amendments
to the tender  offer may be made at any time and from time to time  effected  by
public announcement, the announcement, in the case of an extension, to be issued
no later than 9:00 a.m.,  New York City time, on the next business day after the

                                       40


last previously  scheduled or announced expiration date. Any public announcement
made under the tender offer will be  disseminated  promptly to stockholders in a
manner  reasonably  designed  to  inform  stockholders  of the  change.  Without
limiting  the  manner in which  D&PL may  choose to make a public  announcement,
except as required by applicable  law, D&PL shall have no obligation to publish,
advertise or otherwise  communicate any public announcement other than by making
a release through PR Newswire.

     If D&PL materially changes the terms of the tender offer or the information
concerning  the tender  offer,  D&PL will extend the tender  offer to the extent
required by Rules 13e-4(d)(2), 13e-4(e)(3) and 13e-4(f)(1) promulgated under the
Exchange Act. These rules and certain related  releases and  interpretations  of
the  Securities and Exchange  Commission  provide that the minimum period during
which a tender offer must remain open following material changes in the terms of
the tender offer or information concerning the tender offer (other than a change
in price or a change in  percentage  of  securities  sought)  will depend on the
facts and  circumstances,  including  the relative  materiality  of the terms or
information.

     If D&PL (1)  increases  or  decreases  the  price to be paid for  shares or
increases  or  decreases  the number of shares  being sought in the tender offer
and, if an increase in the number of shares being sought,  such increase exceeds
2% of the outstanding shares, and (2) the tender offer is scheduled to expire at
any time earlier than the  expiration of a period  ending on the tenth  business
day from, and including,  the date that the notice of an increase or decrease is
first  published,  sent or given to security  holders in the manner specified in
this Section 15, then the tender offer will be extended  until the expiration of
such ten business day period.  For the purposes of the tender offer, a "business
day" means any day other than a  Saturday,  Sunday or U.S.  federal  holiday and
consists of the time period from 12:01 a.m.  through  12:00  Midnight,  New York
City time.

16.  Fees and Expenses.

     D&PL has  retained  Georgeson  Shareholder  Communications  Inc.  to act as
information  agent and Illinois Stock  Transfer  Company to act as depositary in
connection with the tender offer.  The information  agent may contact holders of
shares by mail,  telephone,  telegraph and in person,  and may request  brokers,
dealers,  commercial  banks,  trust companies and other nominee  stockholders to
forward  materials  relating  to the  tender  offer to  beneficial  owners.  The
information agent and the depositary each will receive  reasonable and customary
compensation  for their  respective  services,  will be  reimbursed  by D&PL for
specified  reasonable  out-of-pocket  expenses,  and will be indemnified against
certain  liabilities  in  connection  with the tender offer,  including  certain
liabilities under the U.S. federal securities laws.

     D&PL has  retained  UBS  Securities  LLC to act as the  dealer  manager  in
connection with the tender offer. UBS Securities LLC will receive reasonable and
customary  compensation.  D&PL also has agreed to indemnify UBS  Securities  LLC
against  certain  liabilities  in connection  with the tender  offer,  including
liabilities  under the U.S.  federal  securities laws. In the ordinary course of
its trading and brokerage activities,  UBS Securities LLC and its affiliates may
hold  positions,  for their own  accounts  or for those of their  customers,  in
securities of D&PL.

     No fees  or  commissions  will be  payable  by  D&PL to  brokers,  dealers,
commercial banks or trust companies (other than fees to the dealer manager,  the
information agent and the depositary, as described above) for soliciting tenders
of shares under the tender offer.  We urge  stockholders  holding shares through
brokers  or  banks  to  consult  the  brokers  or  banks  to  determine  whether
transaction  costs are  applicable if  stockholders  tender shares  through such

                                       41


brokers  or banks  and not  directly  to the  depositary.  D&PL,  however,  upon
request, will reimburse brokers,  dealers,  commercial banks and trust companies
for customary  mailing and handling  expenses incurred by them in forwarding the
tender offer and related  materials to the  beneficial  owners of shares held by
them as a nominee or in a fiduciary capacity. No broker, dealer, commercial bank
or trust  company has been  authorized  to act as the agent of D&PL,  the dealer
manager,  the  information  agent,  the  depositary  or the  trustee  for D&PL's
employee  plans for purposes of the tender  offer.  D&PL will pay or cause to be
paid all stock  transfer  taxes,  if any, on its  purchase of shares,  except as
otherwise  provided  in  this  document  and  Instruction  10 in the  letter  of
transmittal.

17.  Miscellaneous.

     D&PL is not aware of any jurisdiction  where the making of the tender offer
is not  in  compliance  with  applicable  law.  If  D&PL  becomes  aware  of any
jurisdiction  where the making of the tender offer or the  acceptance  of shares
pursuant thereto is not in compliance with applicable law, D&PL will make a good
faith  effort to comply  with the  applicable  law.  If,  after  such good faith
effort,  D&PL cannot  comply  with the  applicable  law,  D&PL will not make the
tender offer to (nor will tenders be accepted  from or on behalf of) the holders
of shares in that jurisdiction.

     Pursuant to Rule  13e-4(c)(2)  under the Exchange  Act, D&PL has filed with
the  Securities  and Exchange  Commission  an Issuer  Tender Offer  Statement on
Schedule TO, which contains  additional  information  with respect to the tender
offer.   The  Schedule  TO,  including  the  exhibits  and  any  amendments  and
supplements  thereto,  may be  examined,  and copies may be obtained at the same
places  and in the same  manner as is set forth in  Section  10 with  respect to
information concerning D&PL.

     D&PL has not authorized any person to make any  recommendation on behalf of
D&PL as to whether you should  tender or refrain from  tendering  your shares in
the tender offer.  D&PL has not authorized any person to give any information or
to make any  representation in connection with the tender offer other than those
contained in this offer to purchase or in the letter of  transmittal.  If anyone
makes any  recommendation or representation to you or gives you any information,
you must not rely upon that  recommendation,  representation  or  information as
having been authorized by D&PL or the dealer manager.
