                               CONOCO CONNECTION


The following questions and answers explain and constitute CONOCO CONNECTION:

1.   WHAT IS CONOCO CONNECTION?


     CONOCO CONNECTION is a convenient and economical way for new investors to
     make an initial investment in Conoco Class B common stock and for existing
     stockholders to increase their holdings of Conoco common stock.
     Participants in CONOCO CONNECTION may elect to have dividends on both Class
     A and Class B common stock automatically reinvested and to make additional
     cash purchases of the class of common stock they currently hold.



     Participation in CONOCO CONNECTION is entirely voluntary and we give no
     advice regarding your decision to join CONOCO CONNECTION. However, if you
     decide to participate in CONOCO CONNECTION, an enrollment form and reply
     envelope are enclosed for your convenience. Initial Investment Forms for
     new investors in Class B shares are also available, and may be completed,
     on the Internet at www.equiserve.com.


2.   WHAT OPTIONS ARE AVAILABLE UNDER CONOCO CONNECTION?

     CONOCO CONNECTION allows participants to:

     ] Make initial investments in Class B common stock;

     ] Have their dividends on Class A and Class B common stock automatically
       reinvested (fully or partially) in additional shares of common stock.
       DIVIDENDS ON CLASS A SHARES ARE REINVESTED IN CLASS A SHARES. DIVIDENDS
       ON CLASS B SHARES ARE REINVESTED IN CLASS B SHARES; and

     ] Make additional cash purchases of Class A or Class B common stock by
       check, money

                                        8
   10


       order or automatic deductions from their bank accounts. IF YOU CURRENTLY
       HOLD CLASS A STOCK, ANY ADDITIONAL CASH PURCHASES YOU MAKE WILL BE IN
       CLASS A STOCK. IF YOU CURRENTLY HOLD CLASS B STOCK, ANY ADDITIONAL CASH
       PURCHASES YOU MAKE WILL BE IN CLASS B STOCK. IF YOU HOLD BOTH CLASS A AND
       CLASS B STOCK, YOU CAN MAKE ADDITIONAL CASH PURCHASES OF BOTH CLASSES OF
       STOCK.


     As a participant, you can mix and match CONOCO CONNECTION features. For
     example, you can convert your stock certificates into book-entry shares,
     continue to receive dividends in cash, and purchase more shares through
     additional cash purchases.

3.   WHO CAN JOIN CONOCO CONNECTION?

     Anyone is eligible to join CONOCO CONNECTION, whether or not they are
     currently stockholders of Conoco. If you are a resident of a foreign
     country, you should make sure that participation would not violate any laws
     in your home country.


4.  ARE THERE FEES ASSOCIATED WITH PARTICIPATION?



     ] New investors in Class B shares pay a one-time fee of $10, which will be
       deducted from their initial investment funds. Current stockholders
       enrolling to reinvest dividends or make additional cash purchases of the
       class of stock they already own do not pay this fee. Conoco pays the
       brokerage commission on shares purchased with your initial investment.



     ] Conoco pays the fees and brokerage commissions on all other purchases,
       including dividend reinvestments, in addition to the fees for automatic
       deductions from your bank account and the annual maintenance cost of your
       account.



     ] If you ask EquiServe to sell any of your shares, you will be charged a
       $10 fee and


                                        9
   11


       reasonable brokerage commissions (currently $0.12 per share).



     ] Returned checks or failed automatic deduction transactions will result in
       a charge of $25 to you.



5.   HOW DO I JOIN CONOCO CONNECTION?



     ] REGISTERED STOCKHOLDERS. If you are already a Conoco stockholder of
       record (that is, if you own shares that are registered in your name, not
       your broker's name), you may enroll in CONOCO CONNECTION simply by
       completing and returning the enclosed Enrollment Authorization Form.
       Forms may also be obtained by calling EquiServe directly at (800)
       317-4445.



     ] STOCKHOLDERS OWNING CONOCO COMMON STOCK THROUGH A BANK, BROKER OR
       TRUSTEE. If you own shares of Conoco common stock but they are held in
       the name of a bank, broker or trustee in "street" or nominee name, you
       can become a registered holder by instructing your bank, broker or
       trustee to transfer some or all of your shares into your name. You can
       choose whether to receive a physical stock certificate for your shares or
       to hold them in a book-entry account maintained by EquiServe.


       - STOCK CERTIFICATE. Once you receive your stock certificate, you may
         begin to use any or all of the CONOCO CONNECTION services.


       - BOOK-ENTRY SHARES. This is an electronic transfer of your shares from
         your broker's name into your name through the Direct Registration
         System. Simply instruct your broker to conduct a "Withdrawal by
         Transfer" specifying a "statement" or "S" transaction. This will
         establish your book-entry account on Conoco's stockholder records
         maintained by EquiServe, which


                                       10
   12


           includes your brokerage account information.



Once your brokerage account information is established on your book-entry
account with EquiServe, you can commence using any or all of the CONOCO
CONNECTION services. Additionally, at any time you may withdraw all or part of
your shares from CONOCO CONNECTION and electronically deliver them back to your
brokerage account. EquiServe will electronically deliver your shares within two
business days of receiving and accepting your instructions. To change or add
information concerning your bank, broker, or trustee to your account with
EquiServe, you must complete an Authorization to Provide Broker/Dealer
Information Form, available upon request from EquiServe or your bank, broker or
trustee. Your signature(s) on the Authorization Form must be witnessed by a bank
or broker with a Medallion Guarantee. Most banks and brokers participate in the
Medallion Guarantee program. The Medallion Guarantee program ensures that the
individual signing is in fact the owner of the shares. A notary is not
sufficient.


     ] NEW INVESTORS IN CLASS B SHARES. If you are not a current Conoco Class B
       stockholder or if you want to establish a separate account by purchasing
       Class B shares through CONOCO CONNECTION (for example, a joint account
       \with your spouse, or as a custodian for a minor), you may enroll by
       filling out an Initial Investment Form and returning it to EquiServe with
       a payment of at least $250 and no more than $250,000. Initial cash
       payments may be made by check or money order payable to EquiServe. All
       money must be in U.S. funds and drawn

                                       11
   13


       on a U.S. bank or financial institution. Third-party checks will not be
       accepted. As an alternative, you may enroll by accessing CONOCO
       CONNECTION over the Internet at www.equiserve.com and make your initial
       purchase through authorizing automatic deductions from your U.S. bank or
       financial institution.



Conoco will waive the $250 minimum initial investment for investors who choose
to make their initial purchase and subsequent on-going purchases of Class B
common stock through automatic monthly investments. You must authorize an
Automatic Clearing House deduction of a minimum of $50 per transaction from a
designated account at a U.S. bank or financial institution for at least five
consecutive purchases. To do this, you must complete and return an Authorization
Form for Automatic Deductions to EquiServe, together with a voided blank check
or savings account deposit slip for the account from which funds are to be
drawn. An Authorization Form for Automatic Deductions is located on the reverse
of the Initial Investment Form. You should allow four to six weeks for the first
investment to be initiated. You can designate whether you would like funds
deducted once or twice per month on either the first day of the month, the
fifteenth day of the month, or both. Once automatic deductions are initiated,
funds will be drawn from your account on the first and/or fifteenth day of each
month or the next business day if the first and/or fifteenth are not business
days. After fulfilling the minimum purchase requirement, you can stop the
automatic investments by telephoning or writing to EquiServe.



Your enrollment fee of $10 will be subtracted from your initial investment
amount, with the remainder of the funds being applied toward your first
purchase.

6.   CAN I ENROLL VIA THE INTERNET?



     If you are not currently a Conoco Class B stockholder, you may enroll in
     CONOCO CONNECTION and make your initial investment in Class B shares via
     the Internet. You can access the CONOCO CONNECTION prospectus through the
     Internet at www.equiserve.com. After reviewing this document, click on
     "Enrollment" to link to a secure website where, after providing the
     necessary information, you may enroll in CONOCO CONNECTION by authorizing
     automatic deductions of a minimum of $50 per transaction (once or twice per
     month) from a designated account at a U.S. bank or financial institution
     for at least five consecutive purchases.



7.  I AM CURRENTLY A HOLDER OF CLASS A COMMON STOCK. HOW DO I BECOME A HOLDER OF
    CLASS B COMMON STOCK?



     You may directly purchase Class B common stock in the same way that a new
     investor joins CONOCO CONNECTION, regardless of your ownership in Class A
     common stock. You will be required to make a $250 minimum investment in
     Class B stock and pay the $10 enrollment fee. To learn more about this, see
     Question 5, How do I join CONOCO CONNECTION?, and follow the instructions
     for new investors in Class B shares.



8.  I AM CURRENTLY A HOLDER OF CLASS B COMMON STOCK. HOW DO I BECOME A HOLDER OF
    CLASS A COMMON STOCK?



     Current Class B common stockholders may not purchase Class A common stock
     directly through CONOCO CONNECTION. If you wish to purchase Class A common
     stock, you must do so in the open market. After you become a Class A
     holder, you may enroll in CONOCO CONNECTION as a Class A holder and
     reinvest Class A dividends and


                                       13
   15


     make additional cash purchases of Class A common stock.

10. WHAT ARE THE DIVIDEND PAYMENT OPTIONS?


     Participants in CONOCO CONNECTION may choose to reinvest some, all, or none
     of their dividends.

DIVIDENDS ON CLASS A SHARES ARE REINVESTED IN CLASS A SHARES.

DIVIDENDS ON CLASS B SHARES ARE REINVESTED IN CLASS B SHARES.


     ] If you elect full reinvestment, cash dividends paid on all Conoco Class A
       or Class B common stock registered in your name, whether held by you in
       stock certificate form or credited to your book-entry account, will be
       applied to the purchase of additional shares of the class


                                       15
   17

       of Conoco common stock on which the dividend is paid, on or around the
       dividend payment date.


     ] If you elect partial reinvestment of dividends, a portion of your
       dividend proceeds will be paid to you in cash, and the remainder will be
       used to purchase additional shares of the class of Conoco common stock on
       which the dividend is paid, on or around the dividend payment date. To do
       this, you must specify the number of whole shares on which you wish to
       receive cash dividends. The dividends on the balance of your shares will
       be reinvested. You may choose to have cash dividends directly deposited
       in your designated account at a bank or financial institution or sent to
       you by check.



     ] You can also elect to receive all of your dividends in cash rather than
       reinvesting them. If you do not elect a dividend payment option on the
       enrollment form, your dividends will be fully reinvested.



CONOCO EXPECTS ANY FUTURE DIVIDENDS ON SHARES OF CLASS A AND CLASS B COMMON
STOCK TO BE PAID ON THE 10TH OF MARCH, JUNE, SEPTEMBER AND DECEMBER TO
STOCKHOLDERS OF RECORD ON THE 10TH OF THE PRECEEDING FEBRUARY, MAY, AUGUST AND
NOVEMBER.



11. HOW DO I CHANGE MY DIVIDEND PAYMENT OPTION?


     You may change your dividend option, including the amount of dividends
     received in cash or applied to the purchase of additional

                                       16
   18


     shares, at any time by telephoning EquiServe, or by completing and
     submitting a new Enrollment Authorization Form by fax or mail. EquiServe
     must receive any changes before the dividend record date for the change to
     be effective for that dividend. You can obtain the Enrollment Authorization
     Form by contacting EquiServe by telephone or at the address provided in
     Question 9, Who administers CONOCO CONNECTION? How do I contact them? You
     can also obtain a copy of the form on EquiServe's Internet site.



12. HOW CAN I STOP REINVESTING DIVIDENDS?



     You may discontinue reinvestment of dividends at any time by calling or
     writing to EquiServe at the telephone numbers and address set forth in
     Question 9, Who administers CONOCO CONNECTION? How do I contact them?
     However, EquiServe must receive your request before the dividend record
     date for the change to be effective for that dividend.


     Even if you stop reinvestment, your shares will continue to be credited in
     book-entry form to your account at EquiServe unless you request a stock
     certificate. You may request a certificate for all or part of your shares.
     If you request a stock certificate for all of your shares, you will receive
     a stock certificate for any whole share(s) and a check representing the net
     proceeds from the sale of any fractional share.

13. CAN MY CASH DIVIDENDS BE DEPOSITED DIRECTLY TO MY BANK ACCOUNT?



     Through CONOCO CONNECTION's direct deposit feature, you may elect to have
     any cash dividends not reinvested paid by electronic funds transfer to your
     designated bank account. To do this, you must first complete and return a
     Direct Deposit Authorization Form to EquiServe along with a copy of a
     voided blank check or savings account deposit slip. This form is not
     included with your CONOCO CONNECTION material and must be specifically
     requested from EquiServe by calling (800) 870-2340 or obtained on-line at
     www.equiserve.com.



     Forms must be received by EquiServe at least seven business days before the
     dividend record date to be effective for that dividend. Forms received
     after that date will not become effective until the following dividend. You
     may discontinue this feature by writing to EquiServe. You must complete a
     new Direct Deposit Authorization Form if you transfer ownership of shares
     or otherwise establish a new account with EquiServe, close or change the
     designated bank account, or are assigned a new account number by your bank.
     If the proper forms are not completed, you will receive your dividend
     payment by check.

   20


14. HOW DO I MAKE ADDITIONAL CASH PURCHASES OF COMMON STOCK?



ADDITIONAL CASH PURCHASES CAN BE MADE ONLY IN THE CLASS OF COMMON STOCK YOU
ALREADY OWN. IF YOU CURRENTLY HOLD CLASS A STOCK, ANY ADDITIONAL CASH PURCHASES
YOU MAKE WILL BE IN CLASS A STOCK. IF YOU CURRENTLY HOLD CLASS B STOCK, ANY
ADDITIONAL CASH PURCHASES YOU MAKE WILL BE IN CLASS B STOCK. IF YOU HOLD BOTH
CLASS A AND CLASS B STOCK, YOU CAN MAKE ADDITIONAL CASH PURCHASES OF EITHER OR
BOTH CLASSES OF STOCK.


     Additional cash purchases can be made in the following ways:


     ] CHECK OR MONEY ORDER. You can make additional cash purchases of Class A
       or Class B common stock by check or money order for a minimum of $50,
       payable in U.S. dollars to "EquiServe -- Conoco." You should send your
       additional cash purchase payments to EquiServe together with the tear-off
       Transaction Form attached to each account statement or, if making an
       investment while enrolling, with the Enrollment Authorization Form. You
       should also write your CONOCO CONNECTION account number on the check or
       money order.



     ] AUTOMATIC DEDUCTION FROM A BANK ACCOUNT. You may make automatic
       additional cash purchases through an Automated Clearing House withdrawal
       of a specified amount from a designated account at a U.S. bank or
       financial institution. You can designate whether you would like funds
       deducted once or twice per month, either on the first day of the month,
       the fifteenth day of the month, or both. To do this, you must complete
       and return an Authorization Form for Automatic Deductions to


                                       19
   21

       EquiServe, together with a voided blank check or savings account deposit
       slip for the account from which funds are to be drawn. You should allow
       four to six weeks for the first investment to be initiated. Once
       automatic deductions are initiated, funds will be drawn from your account
       on the first and/or fifteenth day of each month or the next business day
       if the first and/or fifteenth are not business days. If you authorize
       automatic deductions once a month, you can specify whether your deduction
       will be made on the first or the fifteenth of the month. Automatic
       deductions will continue until you instruct EquiServe to stop.


     Regardless of how you make your purchase, you will benefit from the full
     investment of your funds, as both whole and fractional shares are credited
     to your account.



15.HOW DO I CHANGE OR STOP AUTOMATIC DEDUCTIONS FROM MY BANK ACCOUNT?


     You may change or stop automatic deductions by notifying EquiServe by
     telephone, mail or fax. You must complete a new Authorization Form for
     Automatic Deductions when you transfer ownership of your shares or
     otherwise establish a new account on EquiServe's records, close or change
     the designated bank account or are assigned a new account number by your
     bank.

     To be effective with respect to a particular investment date, EquiServe
     must receive the new Authorization Form for Automatic Deductions at least
     six business days before the date that funds are scheduled to be withdrawn
     from your account.


16.IS THERE ANY LIMIT ON CASH PURCHASES?



     Total cash purchases in each class of common stock may not exceed $250,000
     per


                                       20
   22


     calendar year, including your initial cash investment, if applicable.



17.HOW ARE SHARES PURCHASED AND PRICED?


     ]SOURCE OF SHARES AND PURCHASE PRICE. Conoco will decide how EquiServe will
      purchase shares for CONOCO CONNECTION. We will instruct EquiServe to
      purchase shares in the open market or to buy newly issued or treasury
      shares directly from Conoco.


      If EquiServe buys shares in the open market, the purchase price will be
      the average price paid per share in the period during which shares are
      purchased. If new shares or treasury shares are issued, the purchase price
      will be the average of the high and low prices based on the New York Stock
      Exchange composite transactions tape as reported in The Wall Street
      Journal on the date they are purchased from Conoco.



18.WHEN WILL SHARES BE PURCHASED?



     ] PURCHASE PERIOD -- INITIAL CASH INVESTMENTS AND ADDITIONAL CASH
       PURCHASES. EquiServe will invest funds in Class A or Class B common
       stock, as applicable, at least once every five business days. EquiServe,
       not Conoco, will determine the actual investment date. If you sign up to
       make automatic purchases of Class A or Class B common stock by
       authorizing EquiServe to deduct $50 or more from your bank account either
       once or twice a month, your payment will be transferred on the first
       and/or fifteenth of each month (as elected by you) or on the next
       business day if the first and/or fifteenth are not business days.



       - You will not be paid any interest on amounts held by EquiServe pending
         investment. EquiServe will return any funds held pending investment,
         provided


                                       21
   23


         that EquiServe receives your request not less than two business days
         before the date that the funds will be invested.



       - To be sure you receive the next dividend to be paid, initial
         investments and additional cash purchases of Class A or Class B common
         stock must be received by EquiServe at least eight business days before
         the record date for that dividend.



     ] REINVESTED DIVIDENDS. When EquiServe purchases shares in the open market
       with dividends to be reinvested, EquiServe will purchase shares at any
       time beginning on the dividend payment date and ending no later than 30
       days after the dividend payment date. If new shares or previously issued
       shares held in Conoco's treasury are issued, EquiServe will purchase
       shares from Conoco on the dividend payment date.


PLEASE NOTE THAT YOU WILL NOT BE ABLE TO
INSTRUCT EQUISERVE TO PURCHASE SHARES
AT A SPECIFIC TIME OR AT A SPECIFIC PRICE.
IF YOU PREFER TO HAVE CONTROL OVER THE
EXACT TIMING AND PRICE OF YOUR
PURCHASE, YOU WILL NEED TO USE YOUR OWN
BROKER.


19.HOW DO I SELL SHARES?


     To sell any shares that you hold in stock certificate form through CONOCO
     CONNECTION, they must first be converted into book-entry shares and
     credited to your account with EquiServe.

     You can sell any of the shares credited to your account with EquiServe by
     accessing your account via the Internet at www.equiserve.com, telephoning
     EquiServe, or completing the Transaction Form attached to your CONOCO
     CONNECTION account

                                       22
   24

     statement and returning it to EquiServe by fax or mail.


     If you have elected to receive cash dividends on some of your shares and
     reinvest dividends on the balance of your shares, unless you specify
     otherwise, the shares on which you are reinvesting dividends will be used
     to fill the sale order first. If those shares are insufficient to fill the
     sale order, shares on which you have elected to receive cash dividends will
     also be sold.



     EquiServe will sell shares daily on the open market through its designated
     broker. To be processed the same day, all sale requests must be received
     before 1:00 p.m. (Eastern time) on a business day during which EquiServe
     and the relevant securities trading markets are open. The sales price will
     be the average price per Class A or Class B share, as applicable, received
     by EquiServe for all sales made that day for CONOCO CONNECTION
     participants. The cash proceeds that you will receive for the shares sold
     will be equal to this average sales price minus the $10 service charge per
     sale and the brokerage commission on the shares sold. See Question 4, Are
     there fees associated with participation?


PLEASE NOTE THAT EQUISERVE WILL NOT ACCEPT INSTRUCTIONS TO SELL ON SOME LATER
DAY OR AT A SPECIFIC TIME OR PRICE. IF YOU WANT TO HAVE CONTROL OVER THE EXACT
TIMING AND SALES PRICES, YOU CAN WITHDRAW THE SHARES YOU WISH TO SELL AND SELL
THEM THROUGH YOUR OWN BROKER.


20.CAN I TRANSFER MY SHARES TO SOMEONE ELSE?



     To transfer some or all of your shares to another person or entity, simply
     call EquiServe. You will be asked to send EquiServe written transfer
     instructions, or you can fill out the transfer instructions on the


                                       23
   25

     reverse of the Transaction Form attached to your account statement. Your
     signature must be "Medallion Guaranteed" by a financial institution. Once
     EquiServe receives all of the necessary forms and documents, your request
     will be processed promptly. This service is free.

     You may transfer shares to new or existing Conoco stockholders. However, a
     CONOCO CONNECTION account will not be opened for a transferee as a result
     of a transfer of less than one full share.


21.WHAT ARE THE RISKS OF PARTICIPATING IN CONOCO CONNECTION?



     ] YOU BEAR ALL RISK OF LOSS THAT MAY RESULT FROM MARKET FLUCTUATIONS IN THE
       PRICE OF CONOCO COMMON STOCK. Your investment risks in Conoco shares
       acquired under CONOCO CONNECTION are no different from your investment
       risks in shares held directly by you. Neither Conoco nor EquiServe can
       assure you a profit or protect you against any loss on shares that are
       purchased through CONOCO CONNECTION.



     ] BY ESTABLISHING CONOCO CONNECTION, CONOCO DOES NOT GUARANTEE THE PAYMENT
       OF FUTURE DIVIDENDS. Conoco's stockholders may not receive future
       dividends. The amount of cash dividends, if any, to be declared and paid
       will depend upon declaration by Conoco's board of directors and upon
       Conoco's financial condition, results of operations, cash flow, the level
       of its capital and exploration expenditures, its future business
       prospects and other related matters that Conoco's board of directors deem
       relevant.


     ] CONOCO AND EQUISERVE WILL INTERPRET AND REGULATE THE OPERATION OF CONOCO
       CONNECTION AS THEY BELIEVE APPROPRIATE. Neither Conoco, EquiServe, nor
       any of their successors or any other

                                       24
   26

       person providing services to CONOCO CONNECTION will be responsible for
       any good-faith acts or omissions when operating or administering CONOCO
       CONNECTION. For example, they are not responsible for:

       - the failure to discontinue reinvestment of dividends or additional cash
         purchases for a participant's account when the participant dies;

       - the price at which Conoco common stock is purchased or sold; or

       - the timing of any purchases or sales.

     However, by participating in CONOCO CONNECTION, you will not waive any
     legal rights you otherwise may have.


22.WHAT REPORTS WILL I RECEIVE?


     To help you in your record keeping, EquiServe will send you the following
     information:


     ] For each initial cash investment, additional cash purchase, sale or
       transfer that you make or receive, a statement detailing the transaction;


     ] For each dividend reinvested, a statement detailing all activity in your
       account for that calendar year; and

     ] For any transactions you make after the fourth quarter dividend, an
       updated cumulative statement detailing all activity in your account for
       that year.


IT IS VERY IMPORTANT TO RETAIN YOUR
STATEMENTS IN A SAFE PLACE FOR TAX
PURPOSES. EQUISERVE WILL CHARGE YOU $5
FOR EACH DUPLICATE STATEMENT YOU
REQUEST FOR ACCOUNT ACTIVITY OLDER
THAN TWO CALENDAR YEARS.


                                       25
   27


     In addition to reports regarding CONOCO CONNECTION, you will receive copies
     of the same communications sent to all other holders of Conoco common
     stock, such as annual reports and proxy statements. You will also receive
     any Internal Revenue Service information returns, if required.



23.WILL I RECEIVE STOCK CERTIFICATES FOR SHARES I PURCHASE THROUGH CONOCO
   CONNECTION?


     You will not receive stock certificates for shares purchased through CONOCO
     CONNECTION. EquiServe will credit those shares in book-entry form to an
     account in your name at EquiServe. Similarly, any stock certificates which
     you may send to EquiServe for deposit will be converted into book-entry
     shares and credited to your account.


24. HOW DO I GET A STOCK CERTIFICATE FOR THE SHARES CREDITED TO MY ACCOUNT?


     To obtain stock certificates for all or some of your shares, you can access
     your account via the Internet at www.equiserve.com, or call, write, or fax
     EquiServe. This service is free.

     Stock certificates for fractional shares cannot be issued. Instead,
     EquiServe will sell any fractional shares and send you a check for the net
     sale proceeds.


25. WHY SHOULD I DEPOSIT MY STOCK CERTIFICATES WITH EQUISERVE? HOW CAN I DO
    THIS?


     Your stock certificates are valuable and expensive to replace if lost or
     stolen. CONOCO CONNECTION offers you the convenience of depositing your
     stock certificates for conversion into book-entry shares at any time.

     Once converted, your book-entry shares are credited to your account and may
     be transferred or sold through CONOCO CONNECTION in the same convenient way

                                       26
   28

     as those shares you acquire through CONOCO CONNECTION.

     Depositing your stock certificates does not require that you reinvest your
     dividends.

     To deposit stock certificates into your CONOCO CONNECTION account, send the
     unendorsed certificates to:

               CONOCO CONNECTION

               C/O EQUISERVE

               P.O. BOX 2598

               JERSEY CITY, NJ 07303-2598


     To insure against loss resulting from mailing certificates, EquiServe will
     provide mail insurance free of charge. To be eligible for certificate
     mailing insurance, you must observe the following guidelines. Certificates
     must be mailed in brown, pre-addressed return envelopes provided by
     EquiServe. Certificates mailed to EquiServe will be insured for the current
     market value (up to $25,000) provided they are mailed first class. You must
     notify EquiServe of any lost certificate claim within 30 calendar days of
     the date the certificates were mailed. The maximum insurance protection
     provided is $25,000 and coverage is available only when the certificate(s)
     are sent to EquiServe in accordance with the guidelines described above.



     Insurance covers the replacement of shares of Conoco stock, but in no way
     protects against any loss resulting from fluctuations in the value of such
     shares from the time you mail the certificates until such time as
     replacement can be completed.



     If you do not use the brown, pre-addressed envelope provided by EquiServe,
     certificates mailed should be insured for possible mail loss for 2% of the
     market value (minimum of $20). This represents your approximate replacement
     cost if the certificates are lost in transit to EquiServe. If you wish to
     deposit


                                       27
   29


     common stock with a market value greater than $25,000, please call
     EquiServe for instructions.



     There is no charge for depositing your stock certificates. You also may
     request a stock certificate for any of your deposited shares at any time,
     free of charge. See Question 24, How do I get a stock certificate for the
     shares credited to my account?



26. WHAT IS THE "BOOK-ENTRY" PROCEDURE FOR HOLDING AND TRANSFERRING SHARES?



     The book-entry procedure for share ownership is a way for stockholders to
     hold and transfer their shares without having to use physical stock
     certificates. Book-entry share ownership provides benefits to Conoco and
     its stockholders by:


     ] eliminating the chance of lost or destroyed certificates;

     ] eliminating the need for certificate storage; and


     ] reducing the costs associated with the issuance and delivery of stock
       certificates.



     At any time, you may request and receive stock certificates for whole
     shares that are held in book-entry form by following the procedures set
     forth in Question 24, How do I get a stock certificate for the shares
     credited to my account? You may also sell shares held in book-entry form by
     following the procedures set out in Question 19, How do I sell shares?


     All Class B shares were initially distributed as book-entry shares, so most
     Class B stockholders already hold their shares in this manner, unless they
     have requested a stock certificate.

27. WHAT ARE THE TAX CONSEQUENCES OF PARTICIPATING IN CONOCO CONNECTION?



     All the dividends paid to you -- whether or not they are reinvested -- are
     considered taxable income to you in the year they are paid by Conoco. Also,
     the Internal Revenue Service will treat as taxable income to you any
     brokerage commissions that Conoco pays on your behalf for purchases of
     shares through Conoco Connection. The total amount will be reported to you
     and to the Internal Revenue Service on IRS Form 1099-DIV, which will be
     mailed by January 31.



     All shares of Conoco common stock that are sold through EquiServe will be
     reported to the IRS as required by law. IRS Form 1099-B will be mailed by
     January 31 to all those who sold stock through CONOCO CONNECTION. The
     1099-B form will include only proceeds you received from the sale of your
     shares. You are responsible for calculating the cost basis of the shares
     you sold and any gain or loss on the sale.


BE SURE TO KEEP YOUR ACCOUNT STATEMENTS FOR INCOME TAX PURPOSES. IF YOU HAVE
QUESTIONS ABOUT THE TAX IMPACT OF ANY TRANSACTIONS YOU ARE CONTEMPLATING, PLEASE
CONSULT YOUR OWN TAX ADVISOR.


28. WILL FEDERAL INCOME TAX BE WITHHELD FROM DIVIDENDS OR SALES PROCEEDS?


     ] UNITED STATES STOCKHOLDERS:

       - Federal law requires EquiServe to withhold an amount, currently 31%,
         from the amount of dividends and the proceeds of any sale of shares if:


          V you fail to certify (either on your Initial Investment Form or on
            Form W-9) to EquiServe that you are not subject to backup
            withholding and


                                       29
   31

             that the taxpayer identification number on your account is correct,
             or

          V the IRS notifies Conoco or EquiServe that you are subject to backup
            withholding.

       - Any amounts withheld will be deducted from your dividends and/or from
         the proceeds of any sale of your shares, and the remaining amount will
         be reinvested or paid as you have instructed.


       - You may obtain a W-9 by calling EquiServe and on the Internet at
         www.equiserve.com.


     ] FOREIGN STOCKHOLDERS:

     Any required United States income tax withholding will be deducted from
     dividends and/or sale proceeds and the remaining amount will be reinvested
     or paid as you have instructed.


29. HOW DO I VOTE MY CONOCO CONNECTION SHARES AT STOCKHOLDER MEETINGS?


     For every stockholder meeting, you will receive a proxy that will cover all
     the Conoco shares you hold both in CONOCO CONNECTION and in the form of
     stock certificates. The proxy will allow you to indicate how you want your
     shares to be voted. Your shares will be voted only as you indicate,
     according to the instructions provided on the proxy card and in the
     materials accompanying the proxy. If you own both Class A shares and Class
     B shares, you will receive separate proxies for each class.


30. WHAT IF CONOCO ISSUES A STOCK DIVIDEND OR DECLARES A STOCK SPLIT OR RIGHTS
    OFFERING?


     If Conoco declares a stock split or stock dividend, the new shares will be
     added to your account or distributed in the form of a stock certificate at
     the discretion of Conoco.

                                       30
   32

     In the event of a stock subscription or other offering of rights to
     stockholders, your rights will be based on the shares held in your account
     plus any shares you hold that are represented by stock certificates. A
     single set of materials will be distributed that will allow you to exercise
     your rights for all shares you own.


31. CAN CONOCO CONNECTION BE CHANGED OR TERMINATED?



     Conoco can change or terminate CONOCO CONNECTION at any time. Conoco also
     reserves the right to terminate any participant's participation in CONOCO
     CONNECTION for any reason at its sole discretion. We will send you written
     notice of any significant changes or upon termination. Changes or
     termination will not affect your rights as a stockholder in any way.



32. WHAT LAW APPLIES TO CONOCO CONNECTION?


     Delaware law governs the terms and conditions in this document, as well as
     those that are described in detail on all forms and account statements.


33. HOW WILL CONOCO USE THE PROCEEDS FROM ITS SALE OF STOCK?



     Conoco currently anticipates that all purchases by CONOCO CONNECTION will
     be made on the open market. Conoco will not receive any proceeds from these
     purchases. However, if CONOCO CONNECTION purchases are made from newly
     issued shares or previously issued shares held in Conoco's treasury, Conoco
     will receive the proceeds and use them for general corporate purposes. We
     are unable to estimate the total amount of these shares or proceeds.

INDEMNIFICATION OF DIRECTORS AND OFFICERS


     Section 145 of the Delaware General Corporation Law provides that a
corporation may indemnify directors and officers as well as other employees and
individuals against expenses (including attorneys' fees), judgments, fines and
amounts paid in settlement in connection with specified actions, suits or
proceedings, whether civil, criminal, administrative or investigative (other
than an action by or in the right of the corporation -- a "derivative action"),
if they acted in good faith and in a manner they reasonably believed to be in or
not opposed to the best interests of the corporation, and, with respect to any
criminal action or proceeding, had no reasonable cause to believe their conduct
was unlawful. A similar standard is applicable in the case of derivative
actions, except that indemnification only extends to expenses (including
attorneys' fees) incurred in connection with the defense or settlement of such
action, and the statute required court approval before there can be any
indemnification where the person seeking indemnification has been found liable
to the corporation. The statute provides that it is not exclusive of other
indemnification that may be granted by a corporation's charter, by-laws,
disinterested director vote, stockholder vote, agreement or otherwise.

     Section 102(b)(7) of the Delaware General Corporation Law permits a
corporation to provide in its certificate of incorporation that a director of
the corporation shall not be personally liable to the corporation or its
stockholders for monetary damages for breach of fiduciary duty as a director,
except for liability (1) for any breach of the director's duty of loyalty to the
corporation or its stockholders, (2) for acts or omissions not in good faith or
which involve intentional misconduct or a knowing violation of law, (3) for
payments of unlawful dividends or unlawful stock repurchases or redemptions, or
(4) for any transaction from which the director derived an improper personal
benefit.

     Article 5E(2) of the certificate of incorporation of Conoco (the
"Registrant") provides that no director shall be personally liable to Conoco or
any of its stockholders for monetary damages for breach of fiduciary duty as a
director, except for liability (1) for any breach of the director's duty of
loyalty to Conoco or its stockholders, (2) for acts or omissions not in good
faith or which involve intentional misconduct or a knowing violation of law, (3)
under section 174 of the Delaware General Corporation Law or (4) for any
transaction from which the director derived an improper personal benefit. Any
repeal or modification of such Article 5E(2) shall not adversely affect any
right or protection of a director of the Registrant for or with respect to any
acts or omissions of such director occurring prior to such amendment or repeal.
Conoco's by-laws provide for indemnification of directors and officers to the
maximum extent permitted by Delaware law.

                                        I
   38


     Conoco has entered into indemnification agreements with each of its
directors and persons named in the prospectus constituting a part of this
Registration Statement (collectively, "Indemnitees"). Such agreements provide
that, to the fullest extent permitted by applicable law, Conoco shall indemnify
and hold each Indemnitee harmless from and against any and all losses and
expenses whatsoever (1) arising out of any event or occurrence related to the
fact that such Indemnitee is or was a director or officer of Conoco, is or was
serving in another capacity with Conoco, or by reason of anything done or not
done by such Indemnitee in such capacity and (2) incurred in connection with any
threatened, pending or completed legal proceeding.


     The Registrant may provide liability insurance for each director and
officer for certain losses arising from claims or changes made against them
while acting in their capabilities as directors or officers of Registrant,
whether or not Registrant would have the power to indemnify such person against
such liability, as permitted by law.

UNDERTAKINGS


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

     The undersigned Registrant hereby undertakes:

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


             (a) To include any prospectus required by Section 10(a)(3) of the
        Securities Act:



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


                                       III
   40

             (c) To include any material information with respect to the plan of
