Note 1  Interim Financial Statements

The interim financial information included herein is unaudited; however, such information reflects all adjustments which are, in the opinion of
management, necessary for a fair presentation of the Companys financial position, results of operations, and cash flows for the interim periods. All such adjustments are of a normal, recurring nature. The results of operations for the first
six months of the year are not necessarily indicative of the results of operations which might be expected for the entire year.

The
financial statements in Deltics 2005 annual report on Form 10-K include a summary of significant accounting policies of the Company and should be read in conjunction with this Form 10-Q. Certain prior period amounts have been reclassified to
conform with the 2006 presentation format.

Note 2  Impact of Recently Effective Accounting Pronouncements

The Company adopted Statement of Financial Accounting Standards (SFAS) No. 123 (R), Share-Based Payment, effective January 1, 2006.
(For additional information regarding the adoption of SFAS No. 123 (R), see Note 4  Stock-Based Compensation.)

In March 2006,
the FASB issued SFAS No. 156, Accounting for Services of Financial Assets. This statement amends SFAS No. 140, Accounting for Transfers and Servicing of Financial Assets and Extinguishments of Liabilities. The effective date of SFAS
No. 156 is generally as of the start of the first fiscal year beginning after September 15, 2006. The Company does not expect the adoption of SFAS No. 156 to have a material effect on its consolidated financial statements.

In June 2006, the FASB issued Interpretation No. 48, Accounting for Income Tax Uncertainties. This interpretation prescribes a recognition
threshold and measurement attribute for the financial statement recognition measurement of a tax position taken or expected to be taken in a tax return. The effective date of FASB Interpretation No. 48 is generally as of the start of the first
fiscal year beginning after December 15, 2006. The Company does not expect the adoption of FASB Interpretation No. 48 to have a material effect on its consolidated financial statements.

Note 4  Stock-Based Compensation

Deltic currently has a stock incentive plan that allows the Company to grant (1) stock options, (2) restricted stock and restricted units,
(3) performance units, and (4) other stock-based awards to executives, other key employees, and nonemployee directors. This plan replaced the Companys previous stock incentive plan in 2002. No further awards will be made under the
previous plan. These plans are discussed in more detail in Note 13  Incentive Plans in Deltics 2005 annual report on Form 10-K.

On January 1, 2006, the Company adopted Statement of Financial Accounting Standards (SFAS) No. 123 (R), which requires companies to account for share-based payment transactions using a fair value-based method and recognize
the related expense in the results of operations. Prior to the adoption of SFAS No. 123 (R), as permitted by SFAS No. 123, Deltic accounted for share-based payments to employees using the recognition and measurement principles of the
Accounting Principles Boards Opinion (APB) No. 25, Accounting for Stock Issued to Employees, and the related interpretations in accounting for those plans. Share-based employee compensation expense was accrued for the
intrinsic value, if any, of stock options or restricted stock granted over the applicable vesting periods using the straight-line method. Options granted by the Company have an exercise price equal to the market value of the underlying common stock
on the date of grant. SFAS No. 123 (R) allowed companies to choose one of two transition methods: (1) the modified prospective transition method or (2) the modified retrospective method. The Company chose to use the modified
prospective transition methodology and, accordingly, Deltic has not restated the results of prior periods.

Note 4  Stock-Based Compensation (cont.)

Under the fair value recognition provisions of SFAS No. 123 (R), stock-based compensation cost is estimated at the grant date based on the fair
value of the award and is recognized as expense over the requisite service period of the award. For valuation of stock options granted subsequent to the adoption of SFAS No. 123 (R), Deltic elected to use a binomial model to estimate fair
value. The fair value of restricted stock awards is determined by reference to the fair market value of the Companys common stock on the date of grant. For restricted stock performance units subsequent to our adoption of SFAS No. 123 (R),
the Monte Carlo simulation is being used to estimate fair value. For all awards subsequent to the adoption of SFAS No. 123 (R), the Company will recognize compensation cost on a straight-line basis over the requisite service period.

Determination of the appropriate fair value model and related assumptions requires estimates of stock price volatilities, forfeiture rates, and
expected option terms. The expected volatility rates are estimated based on the historical and implied volatilities of Deltics common stock. The expected option term represents the average time that options that ultimately vest are expected to
be outstanding and is based on the vesting provisions and historical exercise, cancellation, and expiration patterns. The Company estimates pre-vesting forfeitures when recognizing compensation based on historical rates and forward-looking factors.
These assumptions will be updated at least on an annual basis and on an interim basis if significant changes to the assumptions are warranted.

Deltic issues restricted stock performance units whose vesting is contingent upon meeting certain financial performance goals based upon the Companys total stockholder return compared to the total return of a Paper and Forest Products
Index (the Index) selected by the Compensation Committee and calculated by Standard and Poors. Determining the appropriate amount to expense is based on likelihood of achievement of the stated goals and requires judgement,
including forecasting future financial results. This estimate is revised periodically based on the probability of achieving the required performance targets and adjustments are made as appropriate. The cumulative impact of any revision is reflected
in the period of change. If the financial performance goals are not met, no compensation cost is required and any previously recognized compensation cost is reversed.

The adoption of SFAS No. 123 (R) had an impact on the Companys results of operations. The Consolidated Statement of Income for the three months and six months ended June 30, 2006, included
$310,000 and $595,000, respectively, of stock-based compensation expense reflected in General and Administrative Expenses.

SFAS
No. 123 (R) requires the benefits of tax deductions in excess of recognized compensation cost to be reported as a financing cash flow, rather than as an operating cash flow as required under APB 25 and related interpretations. This
requirement reduced net operating cash flows and increased net financing cash flows for the six months ended June 30, 2006 by $496,000. The cumulative effect related to outstanding restricted stock awards as of December 31, 2005, which are
not expected to vest based on an estimate of forfeitures, was not material.

Assumptions for the 2006 and 2005 valuation of stock options
and restricted stock performance units consisted of the following:

Note 4  Stock-Based Compensation (Cont.)

The expected volatility rate was estimated based on equal weighting of the historical volatility of Deltic common stock over the nine-year trading life
and the implied volatilities of Deltic common stock. The expected term was estimated based on the Companys historical experience of exercise, cancellation, and expiration patterns. The risk-free interest rates are based on the rate for U.S.
Treasury zero coupon bonds over the term of the option. The expected dividend yield is Deltics average dividend yield from 2002 to 2005.

The pre-vesting forfeiture rate used for the six months ended June 30, 2006, was 4.5 percent, which was based on historical rates and forward-looking factors. As required under SFAS No. 123 (R), over time the Company will adjust
the estimated forfeiture rate to agree with actual experience.

For the three months and six months ended June 30, 2005, respectively,
Deltic accounted for stock-based compensation under the intrinsic value method of APB 25. The effect on net income/(loss) and earnings per share if the Company had applied the fair value recognition provisions of the Financial Accounting Standards
Boards Statement of Financial Accounting Standards (SFAS) 123, Accounting for Stock-Based Compensation, consisted of the following:

Note 6  Investment in Del-Tin Fiber

Deltic owns 50 percent of the membership of Del-Tin Fiber, which completed construction and commenced production operations of a medium density fiberboard
(MDF) plant near El Dorado, Arkansas, during 1998.

Prior to August 26, 2004, the Company had agreed to a contingent equity
contribution agreement with Del-Tin Fiber and the group of banks from whom Del-Tin Fiber had obtained its $89,000,000 credit facility. Under this agreement, Deltic and the other 50 percent owner of the joint venture had agreed to fund any deficiency
in contributions to either Del-Tin Fibers required sinking fund or debt service reserve, up to a cumulative total of $17,500,000 for each owner. In addition, each owner had committed to a production support agreement, under which each owner
had agreed to make support obligation payments to Del-Tin Fiber to provide, on the occurrence of certain events, additional funds for payment of debt service until the plant was able to successfully complete a minimum production test. Both owners
had also agreed, in a series of one-year term commitments, to fund any operating working capital needs until the facility was able to consistently generate sufficient funds to meet its cash requirements.

Note 6  Investment in Del-Tin Fiber (cont.)

On August 26, 2004, Del-Tin Fiber refinanced its existing long-term debt by entering into a credit agreement consisting of a letter of credit and
term loan with multiple lending institutions. The funds provided from this credit agreement were used, together with the existing balance in Del-Tin Fibers debt service reserve and bond sinking fund accounts, to redeem $60,000,000 of its
$89,000,000 industrial revenue bonds. Under the new credit agreement, the lenders, on September 1, 2004, loaned Del-Tin Fiber $30,000,000, repayable over five years in equal quarterly installments, beginning December 31, 2004, and issued
on Del-Tin Fibers behalf, a letter of credit in the amount of $29,689,000 to support the remaining industrial revenue bonds originally issued in 1998 by Union County, Arkansas. Concurrent with this event, on August 26, 2004, Deltic
executed a guarantee agreement in connection with the refinancing of the debt of Del-Tin Fiber. Under Deltics guarantee agreement, Deltic unconditionally guarantees the due and punctual payment of 50 percent ($24,595,000 at June 30, 2006)
of Del-Tins obligations under its credit agreement. This new credit agreement of Del-Tin Fiber fully replaces Del-Tin Fibers prior credit facility, resulting in Deltics previous contingent equity contribution agreement of
$17,500,000, the production support agreement, and the need for the series of one-year operating working capital commitments being fully extinguished.

The Company has adopted the provisions of FASB Interpretation No. 45, Guarantors Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others, an
interpretation of FASB Statements No. 5, 57 and 107 and a rescission of FASB Interpretation No. 34 (FIN 45). In accordance with FIN 45, Deltic estimated the fair value of its guarantee of Del-Tin Fibers credit agreement
to be $3,450,000 and included this non-cash amount in the Companys Consolidated Balance Sheet as a long-term liability with an offsetting increase in the Companys investment in Del-Tin Fiber. Deltic is reducing this liability
systematically over the life of the credit agreement, as the Company is released from risk under the guarantee. Simultaneously, the offsetting amount which represents the difference between the Companys recorded investment in Del-Tin Fiber and
its underlying equity in the net assets of the joint venture is being amortized over the same period as the guarantee. The amortization of the guarantee and the basis difference are netted for purposes of financial reporting and result in no net
income statement effect. At June 30, 2006, Deltics remaining liability regarding the guarantee was $2,243,000.

DELTIC TIMBER CORPORATION

AND SUBSIDIARIES

Notes to Consolidated Financial Statements

June 30, 2006

(Unaudited, except
for December 31, 2005)

Note 12  Contingencies

During 2004, the Company disclosed its plans for a 1,170-acre, 187 lot, upscale residential development, The Ridges at Nowlin Creek, on a portion of Deltics large land holdings located west of Little Rock,
Arkansas. A portion of the development is located within the watershed of Lake Maumelle, a principal source of drinking water for the City of Little Rock. On September 19, 2005, the local water utility filed a petition in the Circuit Court of
Pulaski County, Arkansas, to condemn that portion of the development within the lakes watershed, and deposited $3,830,000 as its estimate of just compensation for the land taken. The condemned property includes 99 lots, parts of an additional
20 lots, and proposed access to seven lots.

Upon application by Deltic, on October 11, 2005, the funds were transferred into the
Companys bank account. Deltic has initiated proceedings to have a jury determine the true amount of just compensation for the lands, as well as bringing before the Court a challenge to the propriety of the action. The court hearing regarding
this matter is scheduled to begin later in 2006. Under Arkansas statutes, as interpreted by its courts, condemnation proceedings of this nature by a municipal utility, do not vest fee simple title to the land, until the utility pays the final
judgement of just compensation in the case. Should the utility decide not to pay the final judgement, possession and full title is returned to Deltic and the utility is liable for damages during the period Deltic is dispossessed of its property and
legal fees.

Due to this contingent component of the transaction, no gain will be recorded in the Companys Consolidated Statement of
Income unless fee simple title of the property is transferred from the Company. As a result of the October 11 deposit of the $3,830,000 into Deltics bank account, a long-term deferred revenue liability equal to these cash proceeds
received are included in the Companys Consolidated Balance Sheet in Other Noncurrent Liabilities ended June 30, 2006.

Item 2. Managements Discussion and Analysis of Financial Condition and Results of Operations

Executive Overview

The Company recorded net income of $2.5 million for the second quarter of 2006 compared to $6.4 million for the same period of 2005.
Deltics Woodlands segment provided $6.4 million in operating income during the second quarter, maintaining its role as the established core operation of the Company. The Companys Mills segment reported an operating loss of $.6 million in
2006s second quarter, compared to income of $3.1 million in the corresponding quarter of 2005. Finished lumber sales prices continued to decline in the second quarter of 2006, and the price per thousand board feet (MBF) dropped
$50, or 13 percent, to $335. Lumber sales volumes increased from 69.3 million board feet to 78.2 million in the quarter due to achieving improvements in hourly lumber production rates during the second quarter of 2006. The Real Estate
segment earned $1.4 million in operating income for the second quarter of 2006, which compares to $3.5 million for the same quarter of 2005. Residential lot sales totaled 32 lots, a decrease of 58 when compared to the second quarter of 2005. The
average lot price of $121,400 increased $33,000 per lot, or 37 percent, due primarily to sales mix. Deltic owns a 50 percent interest in Del-Tin Fiber L.L.C., and Deltics share of the joint ventures income for the second quarter of 2006
was $.9 million compared to $.7 million for the same period in 2005.

With the exception of its diversification in real estate development,
Deltic is primarily a wood products producer operating in a commodity-based business environment. This environment is affected by a number of factors, including general economic conditions, interest rates, imports, foreign exchange rates, housing
starts, residential repair and remodeling, commercial construction, industry capacity and production levels, the availability of raw material, and weather conditions. During the course of the second half of 2005 and first six months of 2006, the
Federal Reserve has steadily increased the Federal Funds Rate in an effort to gradually slow economic growth and hold inflation in check. These increases have raised mortgage interest rates, which have slowed housing starts and decreased mortgage
application rates in 2006. Consequently, the high demand and pricing levels for softwood lumber products experienced during 2004 and 2005 have been declining during 2006. Given its relative size and the nature of most commodity markets, the Company
has little or no control over pricing levels for its wood. Therefore, the Company will continue to focus on increasing efficiencies, while reducing controllable manufacturing cost. Sales of real estate are affected by general economic conditions and
interest rates, specifically as such factors are manifested in the Companys operating area of central Arkansas. The rise in mortgage interest rates has been the primary cause of the reduction in Deltics residential lot sales for 2006.

For the second quarter of 2006, pine sawtimber harvest levels decreased 2,033 tons, to 153,807 tons, when compared to the second quarter
of 2005. Pine sawtimber harvest levels for the six months ending June 30, 2006 increased 10 percent, to 367,722 tons, when compared to the same period of last year; however, the Company plans to keep 2006s total pine sawtimber harvest
volume comparable to the level in 2005. Ultimately, the Companys ability to sell pine sawtimber at acceptable prices in the future will be dependent upon the size or existence of markets for manufactured lumber and other wood products. Recent
advances in technology and increased pricing levels for natural gas have resulted in the economic viability of expanded natural gas exploration within the state of Arkansas. One current area of activity, known as the Fayetteville Shale
Play, is an unconventional natural gas reservoir spread across multiple Arkansas counties. During the second quarter of 2006, Deltic leased natural gas drilling rights on approximately 9,800 net mineral acres within the boundaries of the
Fayetteville Shale Play area as currently defined by the Arkansas Oil & Gas Commission. When combined with similar leases from 2005, the total net mineral acres leased to-date is just over 25,000 acres. The Company has leased most of its
mineral acres within the Fayetteville Shale Play, as currently defined by the Arkansas Oil & Gas Commission. The ultimate benefit to Deltic from these mineral leases is contingent on the successful extraction and sale of natural gas from
the area. Activities to sell timberland identified as having a higher and better use or as being non-strategic remain in place. However, Deltic continues to consider these sales only to the extent that the returns on these transactions meet
increased expectations. Timberland designated as higher and better use consists of tracts with market values that exceed the lands worth as a timber growing platform. Non-strategic timberland consists primarily of tracts too small to allow
efficient timber management, those geographically isolated from other Company fee lands, and acreage otherwise not deemed strategic to Deltics operations or growth.

The Mills segment has encountered a declining lumber market which caused the average sales price
per MBF to decrease $50, or 13 percent, to $335 in the second quarter of 2006, from the second quarter average of $385 per MBF in 2005. The average sales price for the first six months of 2006 is down $29 per MBF from the corresponding period in
2005 to an average of $349 per MBF. The Company remains pleased with the improved efficiencies within its sawmills, which have provided a benefit during the current year in the form of reduced unit direct manufacturing cost. As with any commodity
market, the Company expects the historical volatility of lumber prices to continue in the future. The Company continues to anticipate that a significant percentage of logs supplied to both of its sawmills will come from strategically located Company
fee timberlands.

The Real Estate segment closed the sale of 32 residential lots during the second quarter, a reduction of 58 residential
lots when compared to the same quarter in 2005. The average sales price per lot increased 37 percent when compared to the same quarter last year. The reported average sales price for residential lots for a specific period is dependent upon the mix
of lot sales in that period. Deltics lot development plans provide for a mix of lot offerings that represent most real estate market segments for planned communities. Sales activity levels for the Companys real estate developments are
affected by economic conditions that influence the level of housing starts in the central Arkansas region, including general economic conditions and interest rates. As previously mentioned, mortgage rates continued to increase in 2006, which has
lowered the demand for residential lots in the Companys Chenal Valley development. Appropriately, planned capital expenditures for residential lot development has been reduced for 2006, and the Companys current plans are to develop only
76 more lots within Chenal Valley in 2006, construction of which had already begun before the slowdown in lot sales had begun to occur. In Deltics other two active developments, Red Oak Ridge and Chenal Downs, a total of 6 lots were sold,
leaving 67 developed lots in Red Oak Ridge and 16 in Chenal Downs uncommitted as of June 30, 2006. Chenal Downs is fully developed and Deltic does not plan to develop any additional lots within Red Oak Ridge in 2006. Future annual development
activity will be dependent upon the demand for the Companys residential lots.

During 2004, the Company disclosed plans for a
1,170-acre, 187 lot, upscale residential development, The Ridges at Nowlin Creek, on a portion of its land holdings located within the Highway 10 growth corridor west of Chenal Valley. A portion of the development is located within the watershed of
Lake Maumelle, a principal source of drinking water for Little Rock. Due to this environmentally sensitive locale, the Companys plans included the most modern, proven, and best management practices to create a low-impact development in order
to protect water quality in the lake. Even though the local water utility has commissioned the preparation of a new watershed management plan, which supposedly will reflect current scientific principles that would likely be compatible with the
Companys low-impact development plans, in 2005, the utility filed its petition in the Circuit Clerk of Pulaski County, Arkansas, to condemn that portion of the development within the lakes watershed, and deposited its estimate of just
compensation for the land taken. The condemned property includes all of 99 lots, parts of an additional 20 lots, and proposed access to seven lots. Deltic has initiated proceedings to have a jury determine the true amount of just compensation for
the taking of the lands, as well as bringing before the Court a challenge to the propriety of the action. The trial of this matter is scheduled to begin later in 2006. Under Arkansas statutes, as interpreted by its courts, condemnation proceedings
of this nature by a municipal utility do not vest fee simple title to the land until the utility pays the final judgement of just compensation determined in the case. Should the utility decide not to pay the final judgement, possession and full
title is returned to Deltic and the utility is liable for damages during the period Deltic is dispossessed of its property, in addition to legal costs incurred by the landowner. The commencement of this action has caused activities at the Ridges at
Nowlin Creek development to be postponed pending the outcome of the action. Depending upon the outcome of this litigation, the Company will need to further assess the viability of proceeding with development of lots in the development. (For further
discussion, refer to Note 12 to the consolidated financial statements.)

Commercial real estate sales activity is by nature less
predictable than residential activity. No commercial sales occurred in the second quarter of 2006 or 2005. On April 6, 2004, RED Development LLC announced plans for The Promenade at Chenal, a 48-acre, open-air, lifestyle shopping
center. The sales contract regarding this site was originally scheduled to close before the end of 2004. However, as is the inherent unpredictable nature of commercial real estate sales, the initial contract has been extended and is now scheduled to
close later in 2006. Some extensions of similar contracts in the past have been followed by the termination of the commercial sale. No commercial acreage is included in the Chenal Downs or the planned Ridges at Nowlin Creek developments. Red Oak
Ridge is planned to include approximately 80 acres of commercial property. The Company may begin to develop and offer commercial sites as this developments population density increases.

Operating results for Del-Tin Fiber are affected by the overall MDF market and the plants operating
performance. Del-Tin has benefited from an increase in the overall MDF market price and has continued to successfully increase its percentage of higher priced thin-board production. The plant has also been able to maintain the operating performance
improvement from prior years. For the second quarter of 2006, Deltics share of Del-Tin Fibers net income was $.9 million compared to $.7 million in the second quarter of 2005, which included a $.4 million benefit from an insurance claim
related to the first quarter 2005 fire in the plant.

Consolidated

The $3.9 million decrease in net income from the second quarter of 2005 was the result of decreased financial results for the Companys Woodlands, Mills, and Real Estate segments. Included in the consolidated
results for the second quarter of 2006 was the impact of recording previously unaccrued vacation obligations in the amount of $.8 million, $.5 million net of income taxes. The financial results of Del-Tin Fiber improved versus the second quarter of
2005. The Woodlands and Real Estate segments experienced decreases in sales volumes, while the Mills segment had a decrease in average sales price.

Operating income decreased $5.7 million. The Woodlands segment decreased $.2 million due primarily to a decreased pine sawtimber harvest level. Deltics Mills segment operations declined $3.7 million due mainly to a 13 percent decline
in average lumber sales price. Real Estate operating income decreased $2.1 million, primarily the result of a 64 percent decrease in the number of residential lots sold, partially offset by a higher average price per lot. Corporate operating expense
increased $.3 million due to higher general and administrative expenses.

Woodlands

Selected financial and statistical data for the Woodlands segment is shown in the following table.

|Sales price (per acre)           |  | $                      | 1,047 |      | 8,546

Total net sales increased $.7 million, which was driven almost entirely by increases in pine
pulpwood sales, lease income, and revenue from sales of freight charged for timber sold and delivered to other mills, partially offset by a decrease in the sales volume of pine and hardwood sawtimber. Total volumes from the sale of pulpwood
increased during the second quarter of 2006; however, the benefit of this additional volume was somewhat offset by a slight decline in sales prices. Operating income decreased $.2 million due to increases in both freight expense incurred for timber
sold and delivered to other mills and maintenance expenses combined with higher cost of fee timber harvested, partially offset by the increase in net sales.

Total net sales decreased $.9 million, or three percent. This decrease is due to a decreased
lumber sales price of $50 per MBF, or 13 percent, which was partially offset by an increase in sales volume of nine million board feet, or 13 percent. Operating income declined $3.7 million due primarily to the lower average sales price.

Total net sales decreased $3.5 million due to reductions in residential lots sold. The number of
residential lots sold during the second quarter of 2006 decreased by 58 lots, or 64 percent, compared to the same quarter in 2005. The average sales price per lot increased by 37 percent due to sales mix. The decrease in the Real Estate
segments operating income was due primarily to the same factors impacting net sales.

Corporate

Operating expense for Corporate functions remained relatively flat, increasing just $.3 million due primarily to higher incentive plan expense related to
the adoption of SFAS No. 123 (R), Share-Based Payment.

Eliminations

Intersegment sales of timber from Deltics Woodlands to the Mills segment increased $.8 million to $5.9 million. The increase was due to increases in both the volume and price of logs coming into Deltics
sawmills from the Companys fee timberlands. Logs supplied by the Woodlands segment to the Companys sawmills are transferred at prices that approximate market.

Equity in Del-Tin Fiber

For the second quarter of 2006, equity in Del-Tin Fiber improved $.2 million
due to the improvements in both MDF prices and plant operating performance when compared to the second quarter of 2005. The prior-year period benefited from a $.4 million insurance claim related to the first quarter 2005 fire in the plant.

Additional selected financial and statistical data for Del-Tin Fiber is shown in the following table.

|Sales price (per MSF)           |  | $                      | 461  |      | 416 

Average sales price increased 11 percent due to the improvements in the overall MDF market and to
a change in product mix to include a greater percentage of thin board and to an increase in premium-grade production.

Income Taxes

The effective income tax rate was 40 percent and 33 percent in the 2006 and 2005 periods, respectively. The increase was primarily due
to higher effective rates for state income taxes. In the second quarter of 2005, there was a reduction in the estimated valuation allowance related to accumulated state net operating loss carryforwards resulting from projections of increased future
taxable income.

Consolidated

The $2.6 million decrease in net income was the result of declining financial results for the Companys Mills and Real Estate segments and increased Corporate operating expense, partially offset by improvements
in the operating results of the Companys Woodlands segment and an increase in equity in Del-Tin Fiber.

Operating income decreased
$4.7 million. The Woodlands segment increased $1.5 million due primarily to an increased pine sawtimber harvest level and an increased average per-ton pine sawtimber price. The Mills segment decreased $3.8 million due mainly to an eight percent
decrease in average lumber sales price. Real Estate operating income decreased $2.4 million, primarily the result of a 54 percent decrease in the number of residential lots sold, partially offset by a higher average price per lot. Corporate
operating expense increased $.8 million due to higher general and administrative expenses.

Woodlands

Selected financial and statistical data for the Woodlands segment is shown in the following table.

Total net sales increased $3.3 million, which was driven almost entirely by the increase in sales
volume of pine sawtimber combined with an increase in the average sales price per ton. Operating income increased $1.5 million primarily as a result of the increased net sales, partially offset by a $.8 million increase in the cost of fee timber
harvested due to the additional harvest volume.

Total net sales decreased $.2 million, less than one percent, due to the segments eight
percent lower average sales prices, being partially offset by a nine percent increase in sales volume. Total operating income for the Mills declined $3.8 million due to impact of the lower average sales price combined with the cost to produce the
additional volume sold.

Total net sales decreased $3.7 million, or 25 percent, due to reductions in sales of residential
lots and commercial and undeveloped acreage. The number of residential lots sold during 2006 decreased by 68 lots, or 54 percent, compared to 2005. The average sales price per lot increased by 36 percent due to sales mix. The decrease in the Real
Estate segments operating income was due primarily to the same factors impacting net sales.

Corporate

The increase in operating expense for Corporate functions of $.8 million was due primarily to increased incentive plan expense related to the adoption of
SFAS No. 123 (R) and increased salaries and benefits.

Eliminations

Intersegment sales of timber from Deltics Woodlands to the Mills segment increased $2.1 million to $12.7 million. The increase was due to increases
in both the volume and price of logs coming into Deltics sawmills from Company fee timberlands. Logs supplied by the Woodlands segment to the Companys sawmills are transferred at prices that approximate market.

Equity in Del-Tin Fiber

For the
first six months of 2006, equity in Del-Tin Fiber was $1.2 million, an improvement of $1.2 million over break-even results for the same period last year. In 2005, Del-Tin experienced a profitable second quarter which was essentially offset by first
quarter losses reported by the joint venture, as the facilitys first quarter 2005 operations were hindered by a temporary production curtailment caused by a fire sustained at the plant.

Additional selected financial and statistical data for Del-Tin Fiber is shown in the following table.

Average sales price increased four percent due to the improvements in the MDF market and to a
change in product mix to include a greater percentage of thin board and to an increase in premium-grade production.

Income Taxes

The effective income tax rate was 40 percent and 35 percent in the 2006 and 2005 periods, respectively. The increase was primarily due to higher effective rates for state income taxes. During 2005, there was a
reduction in the estimated valuation allowance related to accumulated state net operating loss carryforwards resulting from projections of increased future taxable income.

Liquidity and Capital Resources

Cash Flows and Capital Expenditures

Net cash provided by operating activities totaled $19.2 million for the first half of 2006 compared to $20.7 million for the same period in 2005. Changes
in operating working capital, other than cash and cash equivalents, provided cash of $1 million in the 2006 period and required cash of $.5 million in 2005. The Companys accompanying Consolidated Statements of Cash Flows identify other
differences between net income/(loss) and cash provided by operating activities for each reporting period.

Capital expenditures required
cash of $11.5 million in the current-year period and $14.4 million a year ago. Capital expenditures by segment consisted of the following:

The net change in purchased stumpage inventory to be utilized in the Companys sawmill
operations required cash of $1.3 million in 2006, compared to $.4 million in 2005. The Company made advances to Del-Tin Fiber of $1.7 million during the current period, which decreased by $1.5 million from the corresponding period of 2005 when there
were costs to repair fire damage in the plant during the first quarter, and production curtailments at the facility resulting from downtime due to the fire. In 2006, the Company received $1.7 million in cash distributions from Del-Tin Fiber which
offset the funds advanced. In 2005, there were cash distributions from Del-Tin Fiber of $1.4 million, which were $1.8 million less than the advances for the same period due to that facilitys fire related costs. Deltic received proceeds from
other investing activities of $1.4 million in 2006 and $.8 million in 2005. During 2006, Deltic made $4.5 million in repayments on previous borrowings under its revolving credit facility. In 2005, Deltic borrowed $6 million and made repayments of
debt of $7.7 million. Deltic paid dividends on common stock of $1.9 million during the current period, which was a $.4 million increase over the same period in 2005. In 2006, proceeds from stock option exercises amounted to $1.9 million, an increase
of $1.7 million when compared to 2005. In 2006, the Company adopted SFAS No. 123 (R) which requires the benefits of tax deductions in excess of recognized compensation cost to be reported as a financing cash flow, rather than as an
operating cash flow as required under APB 25 and related interpretations. This amount was $.5 million during the current period.

Financial Condition

Working capital totaled $10.9 million at June 30, 2006, and $7 million at December 31, 2005. Deltics working capital ratio at June 30, 2006, was 1.90 to 1, compared to 1.57 to 1 at the end of
2005. Cash and cash equivalents at the end of the second quarter of 2006 were $5.5 million compared to $1.6 million at the end of 2005. During the first half of 2006, total indebtedness of the Company decreased $4.5 million to $70 million.
Deltics long-term debt to stockholders equity ratio was .339 to 1 at June 30, 2006, compared to .376 to 1 at year-end 2005.

Liquidity

The primary sources of the Companys liquidity are internally generated funds, access to outside financing,
and working capital. The Companys current strategy for growth continues to emphasize its timberland acquisition program, in addition to expanding lumber production as market conditions allow, and developing real estate at Chenal Valley and Red
Oak Ridge.

In December 2000, the Companys Board of Directors authorized a stock repurchase program of up to $10 million of Deltic
common stock. Since December of 2000, the Company has expended $2.1 million under this program, with the purchase of 96,206 shares at an average cost of $22.34 per share; no shares have been purchased in 2006 under this program. In its two
previously completed repurchase programs, Deltic purchased 479,601 shares at an average cost of $20.89 and 419,542 shares at a $24.68 per share average cost, respectively.

Off-Balance Sheet Arrangements, Contractual Obligations, and Commitments

Prior to August 26, 2004, the Company had agreed to a contingent equity contribution agreement with Del-Tin Fiber and the group of banks from whom
Del-Tin Fiber had obtained its $89 million credit facility. Under this agreement, Deltic and the other 50 percent owner of the joint venture had agreed to fund any deficiency in contributions to either Del-Tin Fibers required sinking fund or
debt service reserve, up to a cumulative total of $17.5 million for each owner. In addition, each owner had committed to a production support agreement, under which each owner had agreed to make support obligation payments to Del-Tin Fiber to
provide, on the occurrence of certain events, additional funds for payment of debt service until the plant was able to successfully complete a minimum production test. Both owners had also agreed, in a series of one-year term commitments, to fund
any operating working capital needs until the facility was able to consistently generate sufficient funds to meet its cash requirements.

On August 26, 2004, Del-Tin Fiber refinanced its existing long-term debt by entering into a credit agreement consisting of a letter of credit and term loan with multiple lending institutions. The funds provided from this credit
agreement were used, together with the existing balance in Del-Tin Fibers debt service reserve and bond sinking fund accounts, to redeem $60 million of its $89 million industrial revenue bonds. Under the new credit agreement, the lenders, on
September 1, 2004, loaned Del-Tin Fiber $30 million which will be repayable over five years in equal quarterly installments, beginning December 31, 2004, and issued on Del-Tin Fibers behalf, a letter of credit in the amount of $29.7
million to support the remaining industrial revenue bonds originally issued in 1998 by Union County, Arkansas. Concurrent with this event, on August 26, 2004, Deltic executed a guarantee agreement in connection with the refinancing of the debt
of Del-Tin Fiber. Under Deltics guarantee agreement, Deltic unconditionally guarantees the due and punctual payment of 50 percent ($24.6 million at June 30, 2006) of Del-Tins obligations under its credit agreement. This credit
agreement of Del-Tin Fiber fully replaces Del-Tin Fibers prior credit facility, resulting in Deltics previous contingent equity contribution agreement of $17.5 million, the production support agreement, and the one-year commitment being
fully extinguished.

The Company has adopted the provisions of FASB Interpretation (FIN) No. 45, Guarantors
Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others, an interpretation of FASB Statements No. 5, 57 and 107 and a rescission of FASB Interpretation No. 34. In accordance with FIN
45, Deltic initially estimated the fair value of its guarantee of Del-Tin Fibers credit agreement to be $3.5 million and included this non-cash amount in the Companys Consolidated Balance Sheet as a long-term liability with an offsetting
increase in the Companys investment in Del-Tin Fiber. Deltic is reducing this liability systematically over the life of the credit agreement, as the Company is released from risk under the guarantee. At June 30, 2006, Deltics
remaining liability regarding the guarantee was $2.2 million.

The Company has both funded and unfunded noncontributory defined benefit retirement plans that cover the
majority of its employees. The plans provide defined benefits based on years of service and final average salary. Deltic also has other postretirement benefit plans covering substantially all of its employees. The health care plan is contributory
with participants contributions adjusted as needed; the life insurance plan is noncontributory. (For information about material assumptions underlying the accounting for these plans and other components of the plans, refer to Note 12 to the
consolidated financial statements included in the Companys 2005 annual report on Form 10-K.)

Critical Accounting Policies and Estimates

Critical accounting policies are defined as those that are reflective of significant judgements and uncertainties and potentially result in materially
different results under different assumptions and conditions. The Company has prepared its consolidated financial statements in conformity with accounting principles generally accepted in the United States, which require management to make estimates
and assumptions that affect the reported amounts in these financial statements and accompanying notes. Actual results could differ from those estimates under different assumptions or conditions. The Company has disclosed its critical accounting
policies in its 2005 annual report on Form 10-K, and this disclosure should be read in conjunction with this Form 10-Q. There have been no changes in these identified critical policies, nor have there been any initially adopted accounting policies
having a material impact on reported financial results.

Impact of Recently Effective Accounting Pronouncements

(For information regarding the impact of recently effective accounting pronouncements, refer to Note 2 to the consolidated financial statements.)

Outlook

Pine sawtimber harvest levels
are expected to be 140,000 to 160,000 tons in the third quarter of 2006 and 550,000 to 575,000 tons for the year. Finished lumber production and sales volume will continue to be subject to market conditions, and is estimated at 70 to 80 million
board feet for the third quarter and 280 to 300 million board feet for the year. Residential lot sales are projected to be 15 to 25 lots and 110 to 135 lots for the third quarter and the year, respectively.

Certain statements contained in this report that are not historical in nature constitute forward-looking statements within the meaning of the
Private Securities Litigation Reform Act of 1995. Words such as expects, anticipates, intends, plans, estimates, or variations of such words and similar expressions are intended to identify
such forward-looking statements. These statements reflect the Companys current expectations and involve certain risks and uncertainties, including those disclosed elsewhere in this report. Therefore, actual results could differ materially from

Evaluation of Disclosure Controls and Procedures

Deltic Timber Corporation (Deltic or the Company) has established disclosure controls and procedures to ensure that material
information relating to the Company, including its consolidated subsidiaries, is made known to the officers who certify the Companys financial reports and to other members of senior management and the Board of Directors.

Companys disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934) are effective to ensure that the information required to be disclosed by the Company in the reports that it

Changes in Internal Control Over Financial Reporting

Deltics management, with the Chief
Executive Officer and Chief Financial Officer, have evaluated any changes in the Companys internal control over financial reporting that occurred during the Companys most recent fiscal quarter, and have concluded that there was no change
to Deltics internal control over financial reporting that has materially affected, or is reasonably likely to materially affect, Deltics internal control over financial reporting.
