                          NOTES TO FINANCIAL STATEMENTS
--------------------------------------------------------------------------------

1.    SIGNIFICANT ACCOUNTING POLICIES

Petroleum & Resources Corporation (the Corporation) is registered under the
Investment Company Act of 1940 as a non-diversified investment company. The
Corporation's investment objectives as well as the nature and risk of its
investment transactions are set forth in the Corporation's registration
statement.

Security Valuation--Investments in securities traded on national security
exchanges 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.

Security Transactions and Investment Income--Investment transactions are
accounted 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 distributions
to shareholders are recognized on the ex-dividend date, and interest income is
recognized on the accrual basis.

2.    FEDERAL INCOME TAXES

The Corporation's policy is to distribute all of its taxable income to its
shareholders in compliance with the requirements of the Internal Revenue Code
applicable to regulated investment companies. Therefore, no federal income tax
provision is required. For federal income tax purposes, the identified cost of
securities at June 30, 2006 was $395,128,519 and net unrealized appreciation
aggregated $466,935,589, of which the related gross unrealized appreciation and
depreciation were $469,716,003 and $2,780,414, respectively.

Distributions are determined in accordance with income tax regulations which may
differ from generally accepted accounting principles. Accordingly, annual
reclassifications are made within the Corporation's capital accounts to reflect
income and gains available for distribution under income tax regulations.

3.    INVESTMENT TRANSACTIONS

The Corporation's investment decisions are made by a committee of management,
and recommendations to that committee are made by the research staff.

Purchases and sales of portfolio securities, other than options and short-term
investments, during the six months ended June 30, 2006 were $48,677,573 and
$74,249,686, respectively. Options may be written (sold) or purchased by the
Corporation. The Corporation, as writer of an option, bears the risks of
possible illiquidity of the option markets and from movements in security
values. The risk associated with purchasing an option is limited to the premium
originally paid. A schedule of outstanding option contracts as of June 30, 2006
can be found on page 12.

Transactions in written covered call and collateralized put options during the
six months ended June 30, 2006 were as follows:

4.    CAPITAL STOCK

The Corporation has 5,000,000 authorized and unissued preferred shares without
par value.

On December 27, 2005, the Corporation issued 438,416 shares of its Common Stock
at a price of $33.64 per share (the average market price on December 12, 2005)
to stockholders of record on November 22, 2005 who elected to take stock in
payment of the year-end distribution from 2005 capital gain and investment
income.

During 2006, the Corporation issued 164 shares of its Common Stock at a weighted
average price of $33.67 per share as dividend equivalents to holders of deferred
stock units and restricted stock units under the 2005 Equity Incentive
Compensation Plan.

The Corporation may purchase shares of its Common Stock from time to time at
such prices and amounts as the Board of Directors may deem advisable.

                                                                               5

5.    RETIREMENT PLANS

The Corporation's qualified defined benefit pension plan covers all employees
with at least one year of service. In addition, the Corporation has a
nonqualified defined benefit plan which provides eligible employees with
retirement benefits to supplement the qualified plan. Benefits are based on
length of service and compensation during the last five years of employment. The
Corporation's policy is to contribute annually to the plans those amounts that
can be deducted for federal income tax purposes, plus additional amounts as the
Corporation deems appropriate in order to provide assets sufficient to meet
benefits to be paid to plan participants. During the six months ended June 30,
2006, the Corporation contributed $15,604 to the plans and will contribute an
additional $15,604 to the plans during the remainder of 2006. Any further
contribution cannot be determined with certainty until certain pension reform
legislation, pending in Congress, is passed. Such a contribution, if any, will
not exceed $625,000.

The following table aggregates the components of the plans' net periodic pension
cost for the six months ended June 30, 2006.

Service Cost                                   $ 167,438
Interest Cost                                    163,996
Expected return on plan assets                  (156,096)

Amortization of net loss                         112,681
--------------------------------------------------------
Net periodic pension cost                      $ 306,878
========================================================

The Corporation also sponsors a defined contribution plan that covers
substantially all employees. For the six months ended June 30, 2006, the
Corporation expensed contributions of $50,994. The Corporation does not provide
postretirement medical benefits.

6.    STOCK-BASED COMPENSATION

The Stock Option Plan adopted in 1985 ("1985 Plan") permits the issuance of
stock options and stock appreciation rights for the purchase of up to 895,522
shares of the Corporations's Common Stock at the fair market value on the date
of grant. The exercise price of the options and related stock appreciation
rights is reduced by the per share amount of capital gains paid by the
Corporation during subsequent years. Options are exercisable beginning not less
than one year after the date of grant and stock appreciation rights are
exercisable beginning not less than two years after the date of grant. 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 exercise price and the fair market value of the Common Stock
at the date of surrender. All options terminate 10 years from the date of grant
if not exercised. With the adoption of the 2005 Equity Incentive Compensation
Plan at the 2005 Annual Meeting, no further grants will be made under the 1985
Plan, although unexercised awards granted in 2004 and prior years remain
outstanding.

A summary of option activity under the 1985 Plan as of June 30, 2006, and
changes during the period then ended is presented below:

                    NOTES TO FINANCIAL STATEMENTS (CONTINUED)
--------------------------------------------------------------------------------

Compensation cost resulting from stock options and stock appreciation rights
granted under the 1985 Plan is based on the intrinsic value of the award,
recognized over the award's vesting period, and remeasured at each reporting
date through the date of settlement. The total compensation cost recognized for
the six months ended June 30, 2006 was $146,623.

The 2005 Equity Incentive Compensation Plan ("2005 Plan") permits the grant of
stock options, restricted stock awards and other stock incentives to key
employees and all non-employee directors. The 2005 Plan provides for the
issuance of up to 872,639 shares of the Corporation's Common Stock, including
both performance and nonperformance-based restricted stock. Performance-based
restricted stock awards vest at the end of a specified three year period, with
the ultimate number of awards earned contingent on achievement of certain
performance targets. If performance targets are not achieved, all or a portion
of the performance-based awards are forfeited and become available for future
grants. Nonperformance-based restricted stock awards vest ratably over a three
year period and nonperformance-based restricted stock units (granted to
non-employee directors) vest over a one year period. The 2005 Plan provides for
accelerated vesting in the event of death or retirement. Non-employee directors
also may elect to defer a portion of their cash compensation, with such deferred
amount to be paid by delivery of deferred stock units. Outstanding awards were
granted at fair market value on grant date. The number of shares of Common Stock
which remain available for future grants under the 2005 Plan at June 30, 2006 is
846,163 shares.

The Corporation pays dividends and dividend equivalents on outstanding awards,
which are charged to net assets when paid. Dividends and dividend equivalents
paid on restricted awards that are later forfeited are reclassified to
compensation expense.

A summary of the status of the Corporations's awards granted under the 2005 Plan
as of June 30, 2006, and changes during the period then ended is presented
below:

                                            Weighted Average

   performance-based awards and
   8,468 nonperformance-based
   awards)                        21,493         $33.08
============================================================

Compensation costs resulting from awards granted under the 2005 Plan are based
on the fair value of the award on grant date (determined by the average of the
high and low price on grant date) and recognized on a straight-line basis over
the requisite service period. For those awards with performance conditions,
compensation costs are based on the most probable outcome and, if such goals are
not met, no compensation cost is recognized and any recognized compensation cost
is reversed. The total compensation costs for restricted stock granted to
employees for the period ended June 30, 2006 were $81,175. The total
compensation costs for restricted stock units granted to non-employee directors
for the period ended June 30, 2006 were $80,533. As of June 30, 2006, there were
total unrecognized compensation costs of $577,674 related to nonvested
share-based compensation arrangements granted under the 2005 Plan. Those costs
are expected to be recognized over a weighted average period of 1.98 years.

7.    EXPENSES

The aggregate remuneration paid during the six months ended June 30, 2006 to
officers and directors amounted to $1,378,329, of which $233,587 was paid as
fees and compensation to directors who were not officers. These amounts
represent the taxable income to the Corporation's officers and directors and
therefore differ from the amounts reported in the accompanying Statement of
Operations that are recorded and expensed in accordance with generally accepted
accounting principles.

8.    PORTFOLIO SECURITIES LOANED

The Corporation makes loans of securities to brokers, secured by cash deposits,
U.S. Government securities, or bank letters of credit. The Corporation accounts
for securities lending transactions as secured financing and receives
compensation in the form of fees or retains a portion of interest on the
investment of any cash received as collateral. The Corporation also continues to
receive interest or dividends on the securities loaned. The loans are secured at
all times by collateral of at least 102% of the fair value of the securities
loaned plus accrued interest. Gain or loss in the fair value of securities
loaned that may occur during the term of the loan will be for the account of the
Corporation. At June 30, 2006, the Corporation had securities on loan of
$40,738,724 and held collateral of $41,638,110, consisting of an investment
trust fund which may invest in money market instruments, commercial paper,
repurchase agreements, U.S. Treasury Bills, and U.S. agency obligations.

                                                                               7

             REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
--------------------------------------------------------------------------------

TO THE BOARD OF DIRECTORS AND STOCKHOLDERS OF PETROLEUM & RESOURCES CORPORATION:

In our opinion, the accompanying statement of assets and liabilities, including
the schedule of investments, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of Petroleum & Resources Corporation
(hereafter referred to as the "Corporation") at June 30, 2006, and the results
of its operations, the changes in its net assets and the financial highlights
for each of the fiscal periods presented, in conformity with accounting
principles generally accepted in the United States of America. These financial
statements and financial highlights (hereafter referred to as "financial
statements") are the responsibility of the Corporation's management; our
responsibility is to express an opinion on these financial statements based on
our audits. We conducted our audits of these financial statements in accordance
with the standards of the Public Company Accounting Oversight Board
(United States). Those standards 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, which included confirmation of securities at June
30, 2006 by correspondence with the custodian and brokers, provide a reasonable
basis for our opinion.

Item 11. Controls and Procedures.

Conclusions  of principal officers concerning  controls  and

officers, including the PEO and PFO, concluded that,  as  of
July  12,  2006, the  registrant's  disclosure  controls and
procedures  were reasonably designed so as  to  ensure  that
material  information  relating to the  registrant  is  made
known to the PEO and PFO.

   (b)    There  have  been no significant  changes  in  the
registrant's  internal control over financial  reporting (as
defined in Rule 30a-3(d) under the Investment Company Act of
1940   (17   CFR  270.30a-3(d))  that  occurred  during  the

affected, or is reasonably likely to materially affect,  the
registrant's internal control over financial reporting.

Item 12. Exhibits attached hereto. (Attach certifications as
exhibits)

(1)  Not  applicable. See registrant's response to  Item  2,
above.

(2)  Separate  certifications by the registrant's  principal
executive officer and principal financial officer,  pursuant
to  Section  302  of  the Sarbanes-Oxley  Act  of  2002  and
required by Rule 30a-2 under the Investment Company  Act  of
1940, are attached.



A  certification  by  the registrant's  principal  executive
officer and principal financial officer, pursuant to Section
906 of the Sarbanes-Oxley Act of 2002, is attached.



Pursuant to the requirements of the Securities Exchange  Act
of  1934  and  the  Investment  Company  Act  of  1940,  the
registrant has duly caused this report to be signed  on  its
behalf by the undersigned, thereunto duly authorized.
