                        REPORT OF INDEPENDENT ACCOUNTANTS


To the Participants of the Thrift Plan for Employees of Conoco Inc. and the
Employee Benefit Plans Board of Conoco Inc.

In our opinion, the accompanying statements of net assets available for plan
benefits and the related statement of changes in net assets available for plan
benefits present fairly, in all material respects, the net assets available for
plan benefits of the Thrift Plan for Employees of Conoco Inc. (the "Plan") at
December 31, 2001 and 2000, and the changes in net assets available for plan
benefits for the year ended December 31, 2001 in conformity with accounting
principles generally accepted in the United States of America. These financial
statements are the responsibility of the Plan's management; our responsibility
is to express an opinion on these financial statements based on our audits. We
conducted our audits of these statements in accordance with auditing standards
generally accepted in the United States of America, which require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements, assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

Our audits were conducted for the purpose of forming an opinion on the basic
financial statements taken as a whole. The supplemental schedule of assets (held
at end of year) is presented for the purpose of additional analysis and is not a
required part of the basic financial statements but is supplementary information
required by the Department of Labor's Rules and Regulations for Reporting and
Disclosure under the Employee Retirement Income Security Act of 1974. This
supplemental schedule is the responsibility of the Plan's management. The
supplemental schedule has been subjected to the auditing procedures applied in
the audits of the basic financial statements and, in our opinion, is fairly
stated in all material respects in relation to the basic financial statements
taken as a whole.

NOTE 1 - DESCRIPTION OF THE THRIFT PLAN:

         The following description of the Thrift Plan for Employees of Conoco
Inc. (the "Plan") provides only general information. Members should refer to the
Plan document for the Plan's provisions.

THE PLAN

         The Plan is a defined contribution plan which was established in 1952
by Conoco Inc. (the "Company"). The Company is a wholly-owned subsidiary of
Conoco Inc. (a different company having the same name, referred to as "New
Conoco"). The Plan is subject to the provisions of the Employee Retirement
Income Security Act of 1974 (ERISA) and the Internal Revenue Code (the "Code")
and is a tax-qualified contributory profit sharing plan. The purpose of the Plan
is to encourage employees to save systematically a portion of their current
compensation and to assist them in accumulation of additional financial means
for the time of their retirement. Employees of the Company, including employees
of affiliated companies that have adopted the Plan, 1) who have previously met
the eligibility requirements of the Plan, or 2) who have completed a designated
period of 12 consecutive months during which they complete 1,000 hours or more
of service, or 3) who are regular, full time employees or regular, part-time
employees, are eligible to participate in the Plan.

         Effective January 1, 1999, a separate savings plan, the Thrift Plan for
Retail Employees of Conoco Inc. (the "Retail Plan"), was created for Conoco
retail employees. Retail employees eligible to participate in the Retail Plan
are not eligible to participate in the Plan.

         Prior to October 1, 2001, an eligible participant could authorize the
Company to make a payroll deduction under the Plan ranging from 1% to 19% of
monthly compensation. Effective October 1, 2001, the upper limit of the range
was increased to 38% of monthly compensation. The amount deducted can be
deposited into a before-tax or after-tax account or some combination thereof.
Participants' monthly deductions up to 6% are called basic deposits. The Company
will contribute an amount equal to 100% of the participant's monthly basic
deposits. Effective March 1, 2000, the Company began making a 1% additional
contribution and a 4% discretionary contribution to the Plan in the amount of
the monthly compensation in the month preceding the month in which such
contribution is made of all employees eligible to participate in the Plan in the
month preceding the month in which the contribution is made. The amount of the
discretionary contribution is set once a year and remains in effect for twelve
consecutive months. Effective March 1, 2001, the Company increased its
discretionary contribution to the Plan from 4% to 5%. The Company approved the
5% discretionary contribution again, effective March 1, 2002. The Trustee
acquires units of the Conoco Common Stock Fund with these additional and
discretionary contributions. Units of the Conoco Common Stock Fund so acquired
may be sold at any time at the election of a participant and the proceeds
invested in any of the other available investment options. Subject to certain
limitations, certain participants are eligible to make supplemental deposits,
either as lump sum deposits or deposits in the form of monthly deductions in
excess of 6% of monthly compensation. Due to the application of Internal Revenue
Code discrimination testing requirements, only "non-highly compensated"
participants are currently eligible to make cash lump sum supplemental deposits.

                                       OF
                                   CONOCO INC.

                   NOTES TO FINANCIAL STATEMENTS - (Continued)

                             (Dollars in Thousands)

         Prior to October 1, 2001, a participant with less than five years of
participation credit or service who withdrew any basic deposits would forfeit a
portion of related Company contributions in accordance with the specific Plan
provisions. Also, prior to October 1, 2001, Company contributions would be
suspended for six months if a vested participant made an in-service withdrawal
of any earnings in the before-tax or after-tax accounts, or basic deposits or
Company contributions contributed during the last 24 months. Employee deposits
and matching Company contributions will be suspended for up to 12 months if a
participant withdraws any before-tax contribution prior to age 59-1/2. The 12
month period was reduced to 6 months for periods extending after December 31,
2001. In certain circumstances such a withdrawal may also preclude a participant
from making any before-tax contributions in the year following the withdrawal.
Effective October 1, 2001, immediate vesting was approved and implemented.

         Any vested participant who separates from service, including one who
retires, may elect to make a full account withdrawal at any time. Required
minimum distributions commence in April following the year in which a former
participant reaches age 70-1/2.

         Participants may borrow up to one-half of their nonforfeitable account
balance subject to certain minimum and maximum loan limitations. The loans are
executed by promissory notes and have a minimum term of 12 months and a maximum
term of 60 months, except for qualified residential loans that have a maximum
term of 120 months. Effective October 1, 2001, the 120-month term for qualified
residential loans was increased to 240 months. The loans bore an interest rate
equal to the average rate charged by selected major banks to prime customers for
secured loans. Effective October 1, 2001, the method of determining rate of
interest on a loan was changed to using prime interest rate, as published on the
first business day of the month in which the loan application is received, plus
one percent. The loans are repaid over the term in monthly installments of
principal and interest by payroll deduction. A participant also has the right to
repay the loan in full at any time without penalty.

ADMINISTRATION

         The assets of the Plan are held in two trusts, one of which holds the
assets which comprise the Stable Value Fund (known as the "Master Trust"), and
the other of which holds the remaining assets of the Plan. The designated
trustee of the Master Trust is State Street Bank and Trust Company; the
designated trustee of the remaining assets of the Plan is JPMorgan Chase Bank
(the "Trustees"). The administration of the Plan is vested in the Employee
Benefit Plans Board. The Board of Directors of Conoco Inc. or its delegate may
designate three or more persons to serve on the Employee Benefit Plans Board,
which has the authority to prescribe regulations for the administration of the
Plan, review all claims for benefits under the Plan, and enter into agreements
regarding the administration of the Plan. The Employee Benefit Plans Board also
has the responsibility for directing the Trustee of the Master Trust to enter
into contracts with insurance companies, banks, and other investment
organizations to provide investments giving a stable rate of return to the
Stable Value Fund.

         Brokerage fees, transfer taxes, investment fees and other expenses
incident to the purchase and sale of securities and investments in the Stable
Value Fund, DuPont Stock, Conoco Stock Fund, Mutual Funds, Common/Collective
Trusts, and Blended Funds shall be included in the cost of such securities or
investments, or deducted from the sales proceeds, as the case may be. All

costs related to the management and administration of the Stable Value Fund
investments (such as fees paid to investment managers, fees for wrapper
contracts, custodial and Trustee expenses) are paid out of the assets of the
Stable Value Fund. All administrative expenses not specified in the preceding
two sentences shall be paid out of rebates of record keeping costs and other
discounts in connection with investment vehicles available in the Plan. If such
rebates or other discounts are paid to the Plan, any excess remaining after the
reasonable administration expenses of the Plan have been paid shall be allocated
to the accounts of all participants in the Plan who have an employee account
balance greater than zero on an allocation date designated by the Plan
Administrator. The balance of any administrative expenses not paid as described
above shall be paid ratably by the Company and its affiliated companies
participating in the Plan.

         While the Company has not expressed any intent to terminate the Plan,
it is free to do so at any time. In the event the Plan is terminated, all
affected participants become vested and the distribution of all account balances
will be made based upon the valuation of the participant's account on the
termination date.

NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

INVESTMENT VALUATION AND INCOME RECOGNITION

         The accompanying financial statements are prepared on the accrual basis
of accounting. The Plan's investments are stated at fair value, except for the
Stable Value Fund guaranteed investment contracts (GICs), separate account GICs
(SAGICs), and synthetic guaranteed investment contracts (SYNs), which are stated
at contract value. The Stable Value Fund GICs, SAGICs, and SYNs are fully
benefit responsive and thus, are stated at cost plus accrued interest, using the
contracted interest rates applied to the daily account balances. Mutual Funds
and Blended Funds are valued at quoted market prices that represent the net
asset value of shares held by the Plan at year-end. Common/Collective Trust
Funds are stated at the fair value of all underlying assets as reported by the
applicable custodian. Loans to participants, short-term investments, and cash
are valued at cost that approximates fair value. DuPont common stock and Conoco
common stock are valued at their quoted market prices at year-end. Benefits are
recorded when paid.

         The purchase of shares of Conoco common stock may be made in the open
market or from the Company if it shall have made treasury or authorized but
unissued shares available for such purchases, in which event the purchase price
shall be the closing price of such stock as reported on the New York Stock
Exchange - Composite Transactions on the last day preceding the date of such
purchase from the Company.

         Effective August 7, 1999, dividends from all stock funds are invested
according to the participants' most recent investment direction. Dividend income
is recorded on the ex-dividend date and interest income is recorded when earned.
Realized gains and losses on the sale of the DuPont Stock and Conoco Stock Fund
investment securities are based on daily average cost of the securities sold for
each fund respectively. Purchases and sales are recorded on a trade date basis.

         Investment securities are exposed to various risks, such as interest
rate, market, and credit. Due to the level of risk associated with certain
investment securities, it is at least reasonably possible that changes in
risks in the near term could materially affect the amounts reported in the
Statement of Net Assets Available for Benefits.

USE OF ESTIMATES

         The preparation of financial statements in conformity with accounting
principles generally accepted in the United States of America requires the Plan
Administrator to make estimates and assumptions that affect the reported amounts
in the financial statements. Actual results could differ from those estimates.


NOTE 3 - MASTER TRUST (STABLE VALUE FUND)

         The Stable Value Fund option provided by the Plan is also available to
participants in the Thrift Plan for Retail Employees of Conoco Inc. (the Retail
Plan), sponsored by Conoco Inc.; each plan's beneficial interest in the
commingled Master Trust funds is based on that plan's proportionate share of the
value of the total net assets in the Master Trust. Investment income for each
plan is calculated using this same basis. The Plan's proportionate share of
Master Trust net assets and investment income was approximately 99.9% as of
December 31, 2001 and 2000.

         The Stable Value Fund consists of GICs, SAGICs, SYNs, and short-term
investments and cash.

         The crediting interest rates ranged from 4.80% to 8.31% and 5.56% to
8.31% for the years ended December 31, 2001 and 2000, respectively. The fund's
blended rate of return for the year was 6.53% in 2001 and 6.73% in 2000.

         The crediting rates for most SAGIC and SYN contracts are reset
quarterly and are based on the market value of the underlying portfolio of
assets backing these contracts. Inputs used to determine the crediting rate
include each contract's portfolio market value, current yield-to-maturity,
duration (i.e., the present value of the weighted average life), and market
value relative to contract value. All contracts have a guaranteed rate of 0% or
higher.

         The Master Trust (Stable Value Fund) values as of December 31, 2001 and
2000 are as follows:

NOTE 5 - INCOME TAX STATUS

         The Internal Revenue Service has determined and informed the Company by
a letter dated August 7, 1995 that the Plan is qualified and the trust
established under the Plan is tax-exempt, under the appropriate sections of the
Code. The Plan has been amended since receiving the determination letter.
However, the Plan Administrator and the Plan's tax counsel believe that the Plan
is currently designed and being operated in compliance with the applicable
requirements of the Code. On February 28, 2002, an application for determination
as to the qualification of the Plan, as amended to that date, was submitted to
the Internal Revenue Service.

party-in-interest transactions that are exempt from the prohibited transaction
rules. Still other Plan investments are made in the form of loans to Plan
