                         Notes to Financial Statements

-------------------------------------------------------------------------------

1. Significant Accounting Policies

The Adams Express Company (the Company) is registered under the Investment
Company Act of 1940 as a diversified investment company. The Company's invest-
ment objectives as well as the nature and risk of its investment transactions
are set forth in the Company's registration statement.

Security Valuation -- Investments in securities traded on a national security
exchange are valued at the last reported sale price on the day of valuation.
Over-the-counter and listed securities for which a sale price is not available
are valued at the last quoted bid price. Short-term investments (excluding
purchased options) are valued at amortized cost. Purchased and written options
are valued at the last quoted asked price.

Affiliated Companies -- Investments in companies 5% or more of whose outstand-
ing voting securities are held by the Company are defined as "Affiliated Com-
panies" in Section 2(a)(3) of the Investment Company Act of 1940.

Security Transactions and Investment Income -- Investment transactions are ac-
counted for on the trade date. Gain or loss on sales of securities and options
is determined on the basis of identified cost. Dividend income and distribu-
tions to shareholders are recognized on the ex-dividend date, and interest in-
come is recognized on the accrual basis.

2. Federal Income Taxes

The Company's policy is to distribute all of its taxable income to its share-
holders in compliance with the requirements of the Internal Revenue Code ap-
plicable to regulated investment companies. Therefore, no federal income tax
provision is required. For federal income tax purposes, the identified cost of
securities, including options, at June 30, 2001 was $1,005,353,991, and net
unrealized appreciation aggregated $608,898,927, of which the related gross
unrealized appreciation and depreciation were $734,971,477 and $126,072,550,
respectively.

Distributions are determined in accordance with income tax regulations which
may differ from generally accepted accounting principles. Accordingly, peri-
odic reclassifications are made within the Company's capital accounts to re-
flect income and gains available for distribution under income tax regula-
tions.

3. Investment Transactions

Purchases and sales of portfolio securities, other than options and short-term
investments, during the six months ended June 30, 2001 were $198,517,618 and
$218,361,921, respectively. Options may be written or purchased by the Compa-
ny. The Company, as writer of an option, bears the market risk of an unfavor-
able change in the price of the security underlying the written option. The
risk associated with purchasing options is limited to the premium originally
paid. Option transactions comprised an insignificant portion of operations
during the period ended June 30, 2001. All investment decisions are made by a
committee, and no one person is primarily responsible for making
recommendations to that committee.

4. Capital Stock

The Company has 10,000,000 authorized and unissued preferred shares without
par value.

On October 19, 2000 the Company effected a 3-for-2 stock split. All references
to the number of outstanding shares and per share amounts have been adjusted
retroactively to reflect the stock split.

The Company may purchase shares of its common stock from time to time at such
prices and amounts as the Board of Directors may deem advisable. Transactions
in common stock for 2001 and 2000 were as follows:

-------------------------------------------------------------------------------


On June 30, 2001 the Company held a total of 670,700 shares of its common
stock at a cost of $13,272,370. There were no shares of its common stock held
at December 31, 2000.

The Company has an employee incentive stock option and stock appreciation
rights plan which provides for the issuance of options and stock appreciation
rights for the purchase of up to 2,610,146 shares of the Company's common
stock at 100% of the fair market value at date of grant. Options are exercis-
able beginning not less than one year after the date of grant and extend and
vest over ten years from the date of grant. Stock appreciation rights are ex-
ercisable beginning not less than two years after the date of grant and extend
over the period during which the option is exercisable. The stock appreciation
rights allow the holders to surrender their rights to exercise their options
and receive cash or shares in an amount equal to the difference between the
option price and the fair market value of the common stock at the date of sur-
render. Under the plan, the exercise price of the options and related stock
appreciation

                                                                              5

rights is reduced by the per share amount of capital gain paid by the Company
during subsequent years. At the beginning of 2001, 339,403 options were out-
standing, with a weighted average exercise price of $8.1169 per share. During
the six months ended June 30, 2001, the Company granted options including
stock appreciation rights for 44,214 shares of common stock with a weighted
average exercise price of $20.5776. Stock appreciation rights relating to
15,629 stock option shares were exercised at a weighted average market price
of $19.24 per share and the stock options relating to those rights, which had
a weighted average exercise price of $5.3121 per share, were cancelled. At
June 30, 2001, there were outstanding exercisable options to purchase 126,511
common shares at $3.7033-$20.5417 per share (weighted average price of
$6.7414), and unexercisable options to purchase 241,477 common shares at
$3.7033-$20.5417 per share (weighted average price of $11.3144). The weighted
average remaining contractual life of outstanding exercisable and
unexercisable options is 3.5443 years and 6.0261 years, respectively. Total
compensation expense recognized for the six months ended June 30, 2001 related
to the stock options and stock appreciation rights plan was $(596,795). At
June 30, 2001, there were 1,266,371 shares available for future option grants.

5. Retirement Plans

The Company provides retirement benefits for its employees under a non-con-
tributory qualified defined benefit pension plan. The benefits are based on
years of service and compensation during the last 36 months of employment. The
Company's current funding policy is to contribute annually to the plan only
those amounts that can be deducted for federal income tax purposes. The plan
assets consist of investments in individual stocks, bonds and mutual funds.

The actuarially computed net pension cost credit for the six months ended June
30, 2001 was $208,438, and consisted of service cost of $102,206, interest
cost of $181,123, expected return on plan assets of $448,557, and net amorti-
zation credit of $43,210.

In determining the actuarial present value of the projected benefit obliga-
tion, the interest rate used for the weighted average discount rate was 7.5%,
the expected rate of annual salary increases was 7.0%, and the long-term ex-

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 state-ments are free of material misstatements. 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 presenta-tion. We believe that our audits, which included confirmation
of securities at June 30, 2001, by correspondence with the custodian and
brokers, provide a reasonable basis for our opinion.
