PART I

Item 1. Business

Introduction

Deltic Timber Corporation (Deltic or the Company) is a natural resources company engaged primarily in the growing and harvesting of timber and the manufacture and marketing of lumber. Deltic
owns approximately 437,700 acres of timberland, primarily in Arkansas and north Louisiana. The Companys sawmill operations are located at Ola in central Arkansas (the Ola Mill) and at Waldo in south Arkansas (the Waldo
Mill). In addition to its timber and lumber operations, the Company is engaged in real estate development in central Arkansas. The Company also holds a 50 percent interest in Del-Tin Fiber L.L.C. (Del-Tin Fiber), a joint venture to
manufacture and market medium density fiberboard (MDF). Deltic is a calendar-year company for both financial and income tax reporting.

The Company is organized into four segments: (1) Woodlands, which manages the Companys timberlands; (2) Mills, which consists of Deltics two sawmills that manufacture a variety of lumber products; (3) Real Estate,
which includes the Companys three active real estate developments and a related country club operation; and (4) Corporate, which consists of executive management, accounting, information systems, human resources, purchasing, treasury,
income tax, and legal staff functions that provide support services to the operating business units. (The Company currently does not allocate the cost of maintaining these support functions to its operating units.)

The Companys timberlands consist primarily of Southern Pine, known in the industry as a type of softwood. Deltic considers its
timberlands to be the Companys most valuable asset and the harvest of stumpage to be its most significant source of income; accordingly, Deltic actively manages its timberlands in order to increase productivity and maximize the long-term value
of these timber assets. The Company harvests timber from the timberlands in accordance with its harvest plans and sells such timber in the domestic market or converts it to lumber in its sawmills. Stumpage supplied to the Companys sawmills is
transferred at prices that approximate market. The Company implemented a timberland acquisition program in late 1996. Thus far, the Company has focused its acquisition program on timberland in its current operating area. The Company also initiated a
program in 1999 to identify for possible sale non-strategic timberland and higher and better use lands.

The Companys two sawmills
employ modern technology in order to improve efficiency, reduce labor costs, maximize utilization of the timber resource, and maintain high standards for production quality. In addition, each mill is strategically located near significant portions
of the timberlands. The mills produce a variety of lumber products, including dimension lumber, boards, timbers, decking, and secondary manufacturing products, such as finger-jointed studs. These lumber products are sold primarily to wholesale
distributors, lumber treaters, and truss manufacturers in the South and Midwest and are used mainly in residential construction, roof trusses, and laminated beams. Combined annual permitted capacity of the two mills at December 31, 2005 was
350 million board feet (MMBF). The Companys total finished lumber production was 265 MMBF in 2005 compared to 224 MMBF in 2004 and 215 MMBF in 2003. The current-year increase was due largely to increased operating
efficiencies.

The Companys real estate operations were started in 1985 to add value to former timberland strategically located in
the growth corridor of west Little Rock, Arkansas. Since that time, the Company has been developing Chenal Valley, an approximately 5,000-acre upscale planned community. The property is being developed in stages, and real estate sales to-date have
consisted primarily of residential lots, which are sold to builders or individuals, and commercial sites. In addition to Chenal Valley, Deltic has developed Chenal Downs, a 400-acre development located just outside Chenal Valley, and Red Oak Ridge,
an 800-acre development in Hot Springs, Arkansas. Also, the Company has disclosed plans for The Ridges at Nowlin Creek, an upscale, 1,170-acre, low-impact residential development located just west of Chenal Valley, featuring state-of-the-art
best-management practices to protect water quality in response to its site adjacent to Lake Maumelle (see the Real Estate section of this item for further discussion of The Ridges at Nowlin Creek).

The Del-Tin Fiber plant is located near El Dorado, Arkansas. Construction of the plant was completed, and
initial production began, in 1998. The plant is designed to have an annual capacity of 150 million square feet (MMSF) on a 3/4 inch basis, making it one of the largest plants of its type in the world. MDF, which is used primarily in
the furniture, flooring, and moulding industries, is manufactured from sawmill residuals such as chips, shavings, and sawdust, held together by an adhesive bond.

From the time production began at Del-Tin Fiber in 1998 until the fourth quarter of 2003, both operating and financial performance were below the expectations established at the time that the decision to construct the
plant was made. As a result, on April 25, 2002, Deltic announced that Banc One Capital Markets, Inc. had been retained as financial advisor to assist in the evaluation of strategic alternatives for the Companys investment in Del-Tin
Fiber. Subsequently, Deltics management and Board of Directors completed its review of these strategic alternatives and announced the Company intended to exit the MDF business upon the earliest, reasonable opportunity provided by the market.
As a result of this decision, the Companys evaluation of possible impairment of the carrying value of its investment in the joint-venture was based primarily upon the estimated cash flows from a sale of the Companys interest during 2003
and resulted in a determination that the Companys investment was impaired as of December 31, 2002. The investment was written off to zero.

Due to the Companys commitment to fund its share of any of the facilitys operating working capital needs until the facility was able to consistently generate sufficient funds to meet its cash requirements
or Deltics ownership was sold, the Company recognized losses in Del-Tin Fiber equal to the extent of these advances during 2003. For the year of 2003, such advances approximated the Companys equity share of losses for the plant;
accordingly, the investment in Del-Tin Fiber at December 31, 2003, was zero. The Company also continued to utilize its management resources to work with Del-Tins management and the joint-venture partner to improve operating performance at
the plant. As a result of these improvements, on December 11, 2003, Deltics Board of Directors revised its intent regarding the Companys investment in Del-Tin Fiber and ceased efforts to sell the Companys interest in the joint
venture, while continuing to focus on improving operating and financial results of the plant. Due to this decision, the 2003 evaluation of fair value for the investment was based primarily upon the future net cash flows from Del-Tin Fibers
operations over the remaining life of the plant. The estimated fair value from this evaluation indicated that no impairment existed as of December 31, 2003. In 2004 and 2005, the Company recorded its equity share of the operating results of the
joint venture.

Forest Products Industry

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, foreign exchange rates, housing starts, residential repair and remodeling, commercial construction, industry capacity and production levels, the availability of raw material, and weather conditions. Robust
housing starts in the U.S., fueled by low mortgage interest rates, maintained high demand for softwood lumber products during 2005. This demand resulted in the continuation of high average lumber prices when compared to 2004. Given its relative size
and the nature of most commodity markets, the Company has little or no control over pricing levels for its wood products.

Lumber prices
have historically been, and will remain, volatile. Sawtimber prices have been more stable than lumber prices. Over the three years immediately preceding 2005, sawtimber prices remained relatively flat. However, during 2005, poor weather conditions
and increased sawmill production levels resulted in increases in average sawtimber prices when compared to 2004.

The southern U.S., in
which all of the Companys operations are located, is a major timber and lumber producing region. There are an estimated 209 million acres of timberland in the region, of which approximately 91 million acres contain softwood,
predominately Southern Pine. Unlike other major timber-producing areas in North America, most of this acreage is privately held. The estimated breakdown of



4

##### Table of Contents

ownership of softwood timberland in the southern U.S. is 89 percent private, seven percent national forest, and four percent other public. Although there can
be no assurance, management anticipates that the southern U.S. timber resource will be subject to strong demand for the foreseeable future and also believes that the South will have a strategic advantage over other U.S. timber-producing regions due
to regulatory, geographic, and other factors.

Woodlands

The Company owns approximately 437,700 acres of timberland, primarily in Arkansas and north Louisiana, stocked principally with Southern Pine. Management considers the timberlands to be Deltics most valuable
asset and the harvest of this stumpage to be the Companys most significant source of income.

The approximate breakdown of the
Companys timberland acreage at year-end 2005 consisted of the following:



|                |  |        
|--------------- |  | -------
|                |  | Acres  
|Pine forest     |  | 216,100
|Pine plantation |  | 156,200
|Hardwood forest |  | 23,500 
|Other           |  | 41,900 
|                |  |        
|Total           |  | 437,700
|                |  |        

The Companys timberlands are well diversified by age class. The timberland classified as
pine forest is primarily managed on an all-aged basis and contains mature timber that is ready to be harvested over the next several years and includes stream-management zones. Pine plantations are primarily less than 25 years old, with the majority
ranging in age from 10 to 20 years. Because pine timber generally does not reach sawtimber size until it is 20 to 25 years of age, most of the plantations are not yet included in the Companys pine sawtimber inventory.

Timber Inventory. The Companys estimated standing timber inventory is calculated for each tract by utilizing growth formulas based on
representative sample tracts and tree counts for various diameter classifications. The calculation of pine inventory is subject to periodic adjustments based on sample cruises and actual volumes harvested. The hardwood inventory shown in the
following table is only an approximation, so the physical quantity of such timber may vary significantly from this approximation. Estimated inventory of standing timber as of December 31, 2005, consisted of the following:



|                |  |                        
|--------------- |  | -----------------------
|                |  | Estimated Volume (Tons)
|Pine timber     |  |                        
|Sawtimber       |  | 10,833,700             
|Pulpwood        |  | 5,403,700              
|                | 
|Hardwood timber |  |                        
|Sawtimber       |  | 374,400                
|Pulpwood        |  | 233,300                

The Companys pine sawtimber is either used in its sawmills or sold to third parties.
Products manufactured from this resource include dimension lumber, boards, timbers, decking, and secondary products, used primarily in residential construction. Deltics hardwood sawtimber is sold to third parties and is primarily used in the
production of railroad ties, flooring, and pallets. Pulpwood consists of logs with a diameter of less than nine inches. Both pine and hardwood pulpwood are sold to third parties for use primarily in the manufacture of paper.

Timber Growth. Timber growth rate is an important variable for forest products companies since it
ultimately determines how much timber can be harvested on a sustainable basis. A higher growth rate permits larger annual harvests as replacement timber regenerates. Growth rates vary depending on species, location, age, and forestry management
practices. The growth rate, net of mortality, for Deltics Southern Pine averages five to six percent of standing inventory per annum. The Company considers a 30 to 35 year rotation optimal for most pine plantations.

Timberland Management. Forestry practices vary by geographic region and depend on factors such as soil productivity, weather, terrain, and timber
species, size, age, and stocking. The Company actively manages its timberlands based on these factors and other relevant information to increase productivity and maximize the long-term value of its timber assets. In general, the Companys
timberland management involves harvesting and thinning operations, reforestation, cull timber removal programs, and the introduction of genetically improved seedlings.

Deltic has developed and operates its own seed orchard. Seeds from the orchard are grown by third parties to produce genetically improved seedlings for planting. These seedlings are developed through selective
cross-pollination to produce trees with preferred characteristics, including higher growth rates, fewer limbs, straighter trunks, and greater resistance to disease. However, this process does not involve genetic engineering. The seedlings are
planted in all-aged stands or a site is completely replanted in the case of a final harvest of mature stands. During 2005, about 7,000 acres were planted, primarily using seedlings grown from seeds produced at the orchard facility, with another
approximately 8,300 acres scheduled to be planted in 2006, as the Company continues to reforest understocked tracts. The Company meets or exceeds, in all material respects, the reforestation recommendations of the Arkansas Forestry Commissions
Best Management Practices. In addition, the Company has been certified under the Sustainable Forestry Initiative (SFI) program with regards to its timberland management practices.

The Company actively utilizes commercial thinning practices. Thinning operations consist of the selective removal of trees within a stand, usually a
plantation, and improve overall productivity by enhancing the growth of the remaining trees while generating revenues.

The Companys
cull timber removal program is designed to control undesirable, competitive vegetation in its forests and to increase pine growth rates and reproduction. Deltic treated about 15,000 acres in 2005 and 13,000 acres in 2004 under this program.

Harvest Plans. Management views the timberlands as assets with substantial inherent value apart from the sawmills and intends to
manage the timberlands on a basis that permits regeneration of the timberlands over time. The Company intends to continue to manage the timberlands on a sustainable-yield basis and has no plans to harvest timber on an ongoing basis at levels that
would diminish its timber inventory. In 2005, the Company harvested 581,242 tons of pine sawtimber from its timberlands. Under the current plan, Deltic intends to harvest between 570,000 to 585,000 tons of pine sawtimber in 2006.

The Companys harvest plans are generally designed to project multi-year harvest schedules. In addition, harvest plans are updated at least annually
and reviewed on a monthly basis to monitor performance and to make any necessary modifications to the plans in response to changing forestry conditions, market conditions, contractual obligations, regulatory limitations, and other relevant factors.

Since harvest plans are based on projections of demand, price, availability of timber from other sources, and other factors that may be
outside of the Companys control, actual harvesting levels may vary. Management believes that the Companys harvest plans are sufficiently flexible to permit modification in response to fluctuations in the markets for logs and lumber.

Access. Substantially all of the timberlands are accessible by a system of low impact and low maintenance roads. Deltic generally
uses third-party road crews to conduct construction and maintenance of these roads, and the Company regularly exchanges access easements and cooperates with other area forest products companies and the U.S. Forest Service.

Wildlife Management. The Company has an active wildlife management program for its properties.
Deltic leased approximately 414,000 and 397,000 acres to hunting clubs in 2005 and 2004, respectively. The Companys wildlife biologist has conducted white-tailed deer management clinics throughout Arkansas. In addition, Deltic cooperates with
federal, state, and private agencies in various wildlife studies. The Company also works with the Arkansas Game and Fish Commission to re-establish the black bear population in South Arkansas.

Client-Land Management. In addition to managing its own timberlands, Deltic also manages timberlands owned by others under management contracts
with one-year renewable terms. This program provided harvest planning, silvicultural improvements, and maintenance work for approximately 62,000 acres in 2005.

Timberland Acquisitions.The Company implemented a timberland acquisition program in late 1996. This ongoing program is designed to enable the Company to continue to increase harvest levels, while expanding its
timber inventory. In addition, it will allow the Company to maintain or increase the volume of logs supplied to its sawmills from its own timberlands, when economically feasible.

The Company intends to continue to focus its acquisition program on timberlands that range from fully-stocked to cutover tracts. Unlike other
timber-producing areas of North America, most of the timberland in the southern U.S. is privately held, making it potentially available for acquisition. There can be no assurance that timber properties suitable for acquisition will be identified by
the Company, or that once identified, such properties will ultimately be acquired by the Company.

Deltic formed an acquisition team to
implement its timberland acquisition program. Lands considered for purchase are evaluated based on location, site index, timber stocking, and growth potential. Approximately 123,700 acres of strategically located pine timberland have been added
since the inception of the program. Individual land purchases have ranged from 20 acres to 21,700 acres.

Land Sales. In 1999, the
Company initiated a program to identify for possible sale non-strategic timberland and higher and better use lands. Sales totaled 5,254 acres in 2000, 3,315 acres in 2001, 3,418 acres in 2002, 4,130 acres in 2003, 1,150 acres in 2004, and 45 acres
in 2005.

Leasing. The Company also generates revenue from the leasing of hunting, oil and gas, and other rights on its timberlands.

Mills

The Companys two sawmills
are located at Ola in central Arkansas and at Waldo in south Arkansas, near significant portions of the timberlands. The mills employ modern technology in order to improve efficiency, reduce labor costs, maximize utilization of the timber resource,
and maintain high quality standards of production. Logs processed into lumber are obtained from the timberlands and from public and private landowners. The Company selects logs for processing in its mills based on size, grade, and the prevailing
market price. The Ola Mill is equipped for maximum utilization of smaller diameter logs, while the Waldo Mill can process both smaller and larger diameter logs. The mills produce a variety of products, including dimension lumber, boards, timbers,
decking, and at the larger Waldo Mill, secondary products such as finger-jointed studs. The lumber is sold primarily to wholesale distributors, lumber treaters, and truss manufacturers in the South and Midwest and is used in residential
construction, roof trusses, and laminated beams.

Combined permitted annual production capacity of the two mills increased from 226 MMBF at
year-end 1999 to 300 MMBF at year-end 2003 with a further increase to 350 MMBF at year-end 2005 following the completion of planned upgrades at both mills. The Companys lumber output increased during 2005, with production totaling 265 MMBF
compared to 224 MMBF in 2004 and 215 MMBF in 2003. These increases were due largely to increased operating efficiencies achieved.

Capital Projects. Deltic has invested significant capital in its sawmills in recent years to
increase production capacity and efficiency, decrease costs, and expand the product mix. Major capital projects completed at the Ola Mill over the past several years include: (1) installation of a curve-sawing gang and double-length infeed to
improve log recovery, increase hourly output, and expand product mix; (2) the installation of an optimized edger system to increase lumber recovery; (3) replacement of the planermill with a high-speed planermill and automated sorting
system to increase mill output; (4) construction of a small log processing system which extracts small diameter logs from pulpwood, thus reducing average log costs; (5) addition of a boiler system and steam dry kilns to increase mill
capacity and provide the capability to produce higher value lumber; (6) expansion of log storage capacity to enable increased production as market conditions improve; and (7) primary breakdown redesign and rebuild of the sawmill processing
equipment to improve the infeed of logs and overall flow of green lumber.

At the Waldo Mill, major capital projects completed over the
past several years include:

(1) installation of a curve-sawing gang to improve log recovery, increase hourly output, and expand product mix;
(2) installation of a new edger and optimizer to improve recovery; (3) installation of a log optimization system to improve lumber recovery; (4) extension of the green lumber sorter to increase sawmill throughput; (5) addition of
finger-jointing and remanufacturing facilities which add value to existing production; (6) construction of a new high speed planermill and automated sorting system that provide the finishing capacity necessary to operate two shifts at the
sawmill; (7) installation of a second log debarker in order to further improve hourly throughput capability; and (8) an additional boiler and an upgrade of the lumber drying kilns to increase the mills lumber drying capacity.

Raw Materials. In 2005, the Companys two sawmills processed 1,210,515 tons of logs, obtained from either the timberlands or
purchased from public and private landowners. The timberlands supplied 41 percent, or 499,616 tons, of the mills raw material receipt requirements, while the mills obtained 86 percent of the 581,242 tons of pine sawtimber harvested from the
timberlands.

Various factors, including environmental and endangered species concerns, have limited, and will likely continue to limit,
the amount of timber offered for sale by U.S. government agencies. Because of this reduced availability of federal timber for harvesting, the Company believes that its supply of timber from the timberlands is a significant competitive advantage.
Deltic has historically supplied a significant portion of the timber processed in the sawmills from its timberlands.

In order to operate
its sawmills economically, the Company relies on purchases of timber from third parties to supplement its own timber harvests from the timberlands. The Company has an active timber procurement function for each of its sawmills. As of
December 31, 2005, the Company had under contract 84,415 tons of timber on land owned by other parties, including the U.S. Forest Service, which is expected to be harvested over the next four years. During 2005, the Company harvested
third-party stumpage and purchased logs from third parties totaling 764,062 tons . Of this volume, purchases from the U.S. Forest Service represented seven percent. The balance of such volume was acquired from private lands.

As a result of the reduced availability of federal timber in recent years, demand, along with prices, for privately owned timber has increased, and the
Company has increased and foresees further increases in its harvesting and purchasing activities from private timberlands. Due to this increased demand and higher timber prices, private timber sources have been prompted to sell their timber
commercially. As a result, Deltics sources of private timber are many and diverse. The key factors in a landowners determination of whether to sell timber to the Company are price, the Companys relationships with logging
contractors, and the ability of the Company to demonstrate the quality of its logging practices to landowners. As a result, a landowner will be more likely to sell timber to a forest products company whose own land has been responsibly managed and
harvested. There is a substantial amount of other private timber acreage in proximity to each of Deltics sawmills.

Residual Wood
Products. The Company pursues waste minimization practices at both of its sawmills. Wood chips are usually sold to paper mills or Del-Tin Fiber, and bark is frequently sold for use as fuel. Bark, sawdust, shavings, and wood chips that cannot be
sold are used as hog fuel to fire the boilers that heat the drying kilns. The Company expects to continue to sell a significant portion of its Waldo Mills residual wood chip production to Del-Tin Fiber pursuant to a fiber supply
agreement that expires in 2008.

Transportation. Each mill facility has the capability to ship its lumber by truck or rail.

Cyclical Market. While the cyclicality of the lumber market may occasionally require the interruption of operations at one or both
of the Companys sawmills, suspension of milling activities is unusual. Management is not currently anticipating any interruption of operations at either of Deltics sawmills, but no assurance can be given that market conditions or other
factors will not render such an action economically advisable in the future.

Real Estate

The Companys real estate operations were started in 1985 to add value to former timberland strategically located in the growth corridor of west
Little Rock, Arkansas. Development activities began with the construction of Chenal Ridge, the initial, 85-lot neighborhood in Chenal Valley on the western edge of the Little Rock city limits as of 1985. Since that time the Company has been
developing the remainder of Chenal Valley, an approximately 5,000-acre upscale planned community, centered around two Robert Trent Jones, Jr. designed golf courses. The first golf course was completed in 1990. Construction of the second course began
in 2001, and was opened for play in the summer of 2003. The property has been developed in stages, and real estate sales to date have consisted primarily of residential lots sold to builders or individuals and commercial tracts. In addition to
Chenal Valley, Deltic has developed Chenal Downs, located just outside of Chenal Valley, and is developing Red Oak Ridge, in Hot Springs, Arkansas. Chenal Downs is a 400-acre equestrian development with controlled access, featuring secluded,
five-acre lots. Red Oak Ridge, Deltics first development outside the Little Rock area, is an 800-acre upscale community designed for residential, resort, or retirement living. Also, the Company has 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, and proven, 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 Court 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. Under Arkansas law, Deltic has the right, and has initiated proceedings, to have a jury determine the true amount of
just compensation for the taking of the lands, as well as other damages. The trial of this matter is scheduled to begin 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. Should the utility determine to pay the final judgement, the Company will need to further assess the viability of proceeding with development of lots in the developments remaining acreage. (For further
discussion, refer to Note 16 to the consolidated financial statements.)

Chenal Valley is one of the premier upscale residential and
commercial developments in the Little Rock real estate market. All acreage in Chenal Valley has been annexed by the City of Little Rock. Red Oak Ridge has been similarly annexed by the City of Hot Springs. Both Chenal Downs and the currently
suspended Ridges at Nowlin Creek are located just outside the Little Rock city limits.

Residential Development. Lots were offered
for sale in Chenal Valley during the second half of 1986 with closings beginning in 1987. As of December 31, 2005, 2,586 lots have been developed in 30 neighborhoods and 2,314 lots have been sold, with about 2,086 residences constructed or
under construction.

##### Table of Contents

When fully developed, Chenal Valley will include approximately 4,500 residences. However, the actual number of residences
in Chenal Valley will depend on final land usages and lot densities. The Company has developed lots in a wide variety of market segments. Lot size has ranged from 0.2 acres to 2.25 acres, and lot price has ranged from $25,000 per lot to over
$250,000 per lot.

The first phase of Chenal Downs was opened in December 1997, followed by a second phase in November 2000, with 56 of the
76 lots developed in the two phases sold by the end of 2005. Lot prices in Chenal Downs range from $89,000 to approximately $187,000. In Red Oak Ridge, the first two neighborhoods were offered for sale in late 1998, with a second lot offering in
2005. These neighborhoods offer a choice of either estate-sized homesites, with many overlooking one of two Deltic-constructed lakes, or garden-home lots. As of the end of 2005, 42 of the 135 lots offered have been sold, and prices for lots
currently offered range from about $30,000 to almost $183,000. If commenced, The Ridges at Nowlin Creek will be comprised of estate-sized lots, with expected lot prices ranging from $300,000 to over $500,000.

Commercial Development. Commercial development in Chenal Valley began with the construction of a Company-owned, 50,000-square-foot office
building, which was sold during 2000. Commercial activity to-date has consisted of the sale of approximately 245 acres, including 72 acres in 2003, four acres in 2004, and six acres in 2005. Commercial property sales to-date have consisted of retail
store locations, an office building constructed by the Company on a nine-acre site, multi-family residence sites, convenience store locations, a bank office building site, and outparcels surrounding a retail center constructed and owned by the
Company. Under current development plans, Chenal Valley would include approximately 750 acres of commercial property when fully developed.

The completion of construction of Rahling Road to Chenal Parkway, a major connector street, in 1998 provides greater access to Chenal Valleys commercial acreage. Located at the center of this commercial property is a Company-owned
35,000-square-foot retail center. The retail center was completed in early 2000 and offers retail space for lease. The center is surrounded by 16 outparcels, ranging in size from 0.2 to 1.8 acres. To-date, 11 of these outparcels have been sold.

No commercial acreage is included in the Chenal Downs or the currently suspended Ridges at Nowlin Creek developments. Red Oak Ridge is
planned to include approximately 80 acres of commercial property. The Company will begin to develop and offer commercial sites as population density increases.

Infrastructure. Infrastructure and other improvements to support the development and sale of residential and commercial property are funded directly by the Company and/or through real property improvement
districts. Such properties are developed only when sufficient demand exists and substantially all infrastructure is completed. Future infrastructure investments are primarily necessary for the development and sale of additional property.

Development Amenities. In connection with its Chenal Valley development, the Company developed Chenal Country Club, consisting of the
above-described golf courses, a clubhouse, and related facilities for use by club members. Since its original construction, Deltic has undertaken substantial remodeling and expansion of the clubhouse as the club membership level has increased. In
addition, the Company has built three community parks within the Chenal Valley development for the benefit of the residents of the currently developed residential areas.

Chenal Downs has been developed around an equestrian center, consisting of stables and a training facility, and also includes bridle trails throughout the development. Red Oak Ridges primary amenities currently
consist of two lakes and a community park, constructed by the Company.

Home Construction. Historically, the Companys focus
with regards to residential real estate development has been on lot development only. However, from time to time, Deltic constructs a limited number of speculative homes within its Red Oak Ridge development located in Hot Springs, Arkansas.

Future Development. A number of factors have added significant value to the undeveloped portion of Chenal Valley. Such factors
include: the overall success of Chenal Valley as a residential development and

##### Table of Contents

its image as one of the premier developments in central Arkansas, the continued westward growth of Little Rock, the Companys investment in
infrastructure in the area, and the established residential base which is now large enough to support commercial development. Management expects the undeveloped portion of Chenal Valley to provide growth and development opportunities in the future.

Chenal Downs has been fully developed. Development of Red Oak Ridge is in the early stages, consisting of the construction of two lakes as
the core amenity, initial infrastructure placement, and the first three of several planned neighborhoods.

The Company owns approximately
58,000 mostly contiguous acres, the eastern border of which begins about two miles west of Chenal Valley. Continued development in the Highway 10 growth corridor of west Little Rock has significantly affected land values in the area, and is expected
to create real estate development opportunities for much of this land. As mentioned, in 2004, the Company disclosed its plans for its first real estate development in this acreage. If commenced, this 1,170 acre upscale development, called The Ridges
at Nowlin Creek, is slated to be comprised of estate-sized lots.

Undeveloped Acreage. The success of Chenal Valley has increased
the value of the Companys undeveloped real estate surrounding and within the development. Sales of undeveloped real estate amounted to zero acres in 2003, 94 acres in 2004, and seven acres in 2005.

Del-Tin Fiber

Deltic owns 50 percent of the
membership interest of Del-Tin Fiber, a joint venture to manufacture and market MDF. The Del-Tin Fiber plant is located near El Dorado, Arkansas. Construction of the plant was completed, and initial production began, in 1998. The plant is designed
to have an annual capacity of 150 million square feet (MMSF), on a 3/4-inch basis, making it one of the largest plants of its type in the world.

From the time production began at Del-Tin Fiber in 1998 until the fourth quarter of 2003, both operating and financial performance were below the expectations established at the time that the decision to construct the
plant was made. As a result, on April 25, 2002, Deltic announced that Banc One Capital Markets, Inc. had been retained as financial advisor to assist in the evaluation of strategic alternatives for the Companys investment in Del-Tin
Fiber. Subsequently, Deltics management and Board of Directors completed its review of these strategic alternatives and announced the Company intended to exit the MDF business upon the earliest, reasonable opportunity provided by the market.
As a result of this decision, the Companys evaluation of possible impairment of the carrying value of its investment in the joint-venture was based primarily upon the estimated cash flows from a sale of the Companys interest during 2003
and resulted in a determination that the Companys investment was impaired as of December 31, 2002. The investment was written off to zero.

Due to the Companys commitment to fund its share of any of the facilitys operating working capital needs until the facility was able to consistently generate sufficient funds to meet its cash requirements
or Deltics ownership was sold, the Company recognized losses in Del-Tin Fiber equal to the extent of these advances during 2003. For the year of 2003, such advances approximated the Companys equity share of losses for the plant;
accordingly, the investment in Del-Tin Fiber at December 31, 2003, was zero. The Company also continued to utilize its management resources to work with Del-Tins management and the joint-venture partner to improve operating performance at
the plant. As a result of these improvements, on December 11, 2003, Deltics Board of Directors revised its intent regarding the Companys investment in Del-Tin Fiber and ceased efforts to sell the Companys interest in the joint
venture, while continuing to focus on improving operating and financial results of the plant. Due to this decision, the 2003 evaluation of fair value for the investment was based primarily upon the future net cash flows from Del-Tin Fibers
operations over the remaining life of the plant. The estimated fair value from this evaluation indicated that no impairment existed as of December 31, 2003. In 2004 and 2005, the Company recorded its equity share of the operating results of the
joint venture.

Medium Density Fiberboard. MDF, which is used primarily in the furniture, flooring, and molding
industries, is manufactured from sawmill residuals such as chips, shavings, and sawdust, held together by an adhesive bond. Although the technology has existed for decades, recent improvements in the manufacture of MDF have increased both the
quality and consistency of the product. MDF, with its Areal wood appearance and the ability to be finely milled and accept a variety of finishes, competes primarily with lumber.

Production. The plant produced 141 MMSF of MDF in 2005 versus 148 MMSF of MDF in 2004 and 133 MMSF of MDF in 2003. Prior to 2003, start-up
difficulties and operational problems with the plants press and heat energy system limited production to levels significantly below capacity. The problems with the press were corrected in mid-1999. As natural gas prices escalated during the
last half of 2000, the decision was made in late January 2001, to temporarily suspend operations until the heat energy system could be modified. Following completion of a capital project to modify this system, the plant resumed operations in June
2001. Rectification of the heat energy system has enabled the plants operations to increase production levels closer to the plants capacity of 150 MMSF per year, as market conditions improved. In addition, manufacturing cost per thousand
square feet has decreased, as certain variable costs of manufacturing have been lowered and fixed costs for the facility are being allocated to the increased production.

Raw Materials. The Del-Tin plant provides an additional outlet for wood chip production from the Waldo Mill. Pursuant to a fiber supply agreement that expires in 2008, the Company has agreed to sell, and
Del-Tin Fiber to buy, substantially all residual wood chips from the Waldo Mill. In addition, Del-Tin Fiber has an option to purchase residual wood chips from the Ola Mill and pulpwood chips, shavings, and sawdust from the Waldo Mill. During 2005,
2004, and 2003, Deltic sold approximately $3,868,000, $3,890,000, and $4,099,000, respectively, of these lumber manufacturing by-products to Del-Tin Fiber.

Discontinued Agriculture Operations

In August 2000, the Companys Board of Directors approved the disposal of
Deltics former Agriculture segment assets, subject to using the sales proceeds to purchase additional Southern Pine timberland, via tax-deferred exchanges. Deltic engaged an agricultural land consulting and brokerage firm to act as advisors in
evaluating and marketing about 50,000 acres (approximately 38,800 acres net to Deltic) of farmland located in northeast Louisiana. The sale of all farmland and related agriculture operational assets, as well as the acquisition of replacement
property in the form of timberland, was successfully concluded during 2001. This initiative provided the Company a significant and unique opportunity to advance its strategy of growing its core forest products business.

Products and Competition

The Companys
principal forest products are timber; timberland; lumber products, primarily finished lumber; residual wood products; and real estate.

Timber. Timber harvested from the timberlands is utilized by the Companys sawmills or sold to third parties. The Companys timber sales to third parties accounted for approximately nine percent, six percent, and six
percent of consolidated net sales in 2003, 2004, and 2005, respectively.

The Company competes in the domestic timber market with numerous
private industrial and non-industrial land and timber owners. Competitive factors with respect to the domestic timber market generally include price, species and grade, proximity to wood manufacturing facilities, and accessibility.

Land Sales. Timberland sold by the Company to third parties consists of both non-strategic timberland and lands with potential for higher and
better use, and amounted to six percent, one percent, and less than one percent of consolidated net sales in 2003, 2004, and 2005, respectively.

Lumber Products. The Companys sawmills produce a wide variety of products, including dimension lumber, boards, timbers, decking, and secondary products such as finger-jointed studs. Lumber is sold primarily to wholesaler
distributor, lumber treaters, and truss manufacturers in the South and Midwest and is



12

used in residential construction, roof trusses, and laminated beams. During 2003, 2004, and 2005, lumber sales as a percentage of consolidated net sales were
approximately 45 percent, 59 percent, and 60 percent, respectively.

The forest products market is highly competitive with respect to price
and quality of products. In particular, competition in the commodity-grade lumber market in which the Company competes is primarily based on price. Deltic competes with other publicly held forest products companies operating in the U.S., many of
which have significantly greater financial resources than the Company, as well as privately held lumber producers. The Company also competes with producers in Canada and overseas, regions that have increased their share of the U.S. lumber market in
recent years. In addition, Deltics management expects the Companys products to experience additional increased competition from engineered wood products and other substitute products. Due to the geographic location of Deltics
timberlands and its high-quality timber, in addition to the Companys active timber management program, strategically located and efficient sawmill operations, and highly motivated workforce; Deltic has been able to compete effectively.

Residual Wood Products. The Companys sawmills produce wood chips, shavings, sawdust, and bark as by-products of the
conversion process. During 2003, 2004, and 2005, sales of these residual products accounted for seven percent, eight percent, and nine percent, respectively, of Deltics consolidated net sales. Wood chips are the primary source of residual
sales and are typically sold to Del-Tin Fiber or to paper mills. In 2005, Deltics sawmills produced 381,835 tons of wood chips. The Company expects to continue to sell a significant portion of its wood chip production to Del-Tin Fiber for use
in the production of MDF.

Real Estate. The Company develops and markets residential lots and commercial sites. Deltic generally
provides the supporting infrastructure. Residential lots are sold to homebuilders and individuals, while commercial sites are sold to developers and businesses. The Company also sells undeveloped acreage. During 2003, 2004, and 2005, the sales of
residential lots, commercial sites, and undeveloped acreage as a percentage of consolidated net sales were 21 percent, 17 percent, and 15 percent, respectively. The sale of commercial property can have a significant impact on the Companys
sales, but is unpredictable and irregular.

Seasonality

The Companys operating segments are subject to variances in financial results due to several seasonal factors. The majority of timber sales are typically generated in the first half of the year due primarily to
weather conditions and historically stronger timber prices. Increased housing starts during the spring usually push lumber prices up. Forestry operations generally incur expenses related to silvicultural treatments which are applied during the fall
season to achieve maximum effectiveness.

Business Segment Data

Information concerning net sales, operating income, and identifiable assets attributable to each of the Companys business segments is set forth in Item 7, Managements Discussion and
Analysis; and Note 17 to the consolidated financial statements in Item 8, Financial Statements and Supplementary Data, of Part II of this report.

Decline in Availability of Federal Timber

Various factors, including environmental and endangered
species concerns, have limited, and will likely continue to limit, the amount of timber offered for sale by certain U.S. government agencies, which historically have been major suppliers of timber to the U.S. forest products industry. During 2005,
the Company acquired approximately nine percent of its timber supply for its Ola Mill from federal sources, primarily the Ouachita and Ozark National Forests. Any future decline in the availability of timber from



13



---

##### Table of Contents

federally owned lands will require that the Company, in order to supply the Ola Mill, rely more heavily on harvests from the Companys timberlands,
including harvests from timberlands acquired in the future to the extent that suitable opportunities arise, and on the acquisition of timber from other sources, such as private timber owners. The Companys Waldo Mill does not currently process
any timber acquired from federal sources.

Environmental Matters

The Company is subject to extensive and changing federal, state, and local environmental laws and regulations relating to the protection of human health and the environment, including laws relating to air and water
emissions, the use of herbicides on timberlands, regulation of wetlands, and the protection of endangered species. Environmental legislation and regulations, and the interpretation and enforcement thereof, are expected to become
increasingly stringent. The Company has made, and will continue to make, expenditures to comply with such requirements in the ordinary course of its operations. Historically, these expenditures have not been material and the Company expects that
this will continue to be the case. Liability under certain environmental regulations may be imposed without regard to fault or the legality of the original actions, and may be joint and several with other responsible parties. As a result, in
addition to ongoing compliance costs, the Company may be subject to liability for activities undertaken on its properties prior to its ownership or operation and by third parties, including tenants. The Company is not involved with any such sites as
of this time. The Company leases the rights to drill for oil and gas on some of its lands to third parties. Pursuant to these leases, the lessee indemnifies the Company from environmental liability relating to the lessees operations. Based on
its present knowledge, including the fact that the Company is not currently aware of any facts that indicate that the Company will be required to incur any material costs relating to environmental matters, and currently applicable laws and
regulations, the Company believes that environmental matters are not likely to have a material adverse effect on the Companys financial condition, results of operations, or liquidity.

In addition, the federal Endangered Species Act protects species threatened with possible extinction and restricts timber harvesting
activities on private and federal lands. Certain of the Companys timberlands are subject to such restrictions due to the presence on the lands of the red cockaded woodpecker, a species protected under the Act. There can be no assurance that
the presence of this species or the discovery of other protected species will not subject the Company to future harvesting restrictions. However, based on the Companys knowledge of its timberlands, the Company does not believe that its ability
to harvest its timberlands will be materially adversely effected by the protection of endangered species.

Access to SEC Filings

The Company maintains an internet website at www.deltic.com. The Company makes available free of charge under the Investor Relations section of its
website its annual report on Form 10-K, quarterly reports on Form 10-Q, and current reports on Form 8-K, all amendments to any of those reports and other filings, as soon as reasonably practicable after providing such reports to the Securities and
Exchange Commission.

Item 1A. Risk Factors

Cyclicality of Forest Products Industry

The Companys results of operations are, and will continue to be, affected by the cyclical nature of the forest products industry. Prices and demand
for logs and manufactured wood products have been, and in the future can be expected to be, subject to cyclical fluctuations. The demand for logs and lumber is primarily affected by the level of new residential construction activity, which activity
is subject to fluctuations due to changes in economic conditions, mortgage interest rates, population growth, weather conditions and other factors. Decreases in the level of residential construction activity will be reflected in reduced demand for
logs and lumber resulting in lower prices for the Companys products and lower revenues, profits, and cash flows. In addition to housing starts, demand for wood products is also significantly affected by repair and remodeling activities and
industrial uses, demand for which has historically been less cyclical. Furthermore, changes in industry supply of timber have an effect on prices. Although the Company believes that sales of timber by United States government agencies will remain at
relatively low levels for the foreseeable future, any reversal of policy that substantially increased such sales could significantly reduce prices for logs and lumber, which could have a material adverse effect on the Company. Furthermore, increased
imports from Canada and other foreign countries could reduce the prices the Company receives for its products.

Decline in Availability
of Federal Timber

Various factors, including environmental and endangered species concerns, have limited, and will likely continue to
limit, the amount of timber offered for sale by certain United States government agencies, which historically have been major suppliers of timber to the United States forest products industry. The Company acquires a portion of its timber supply for
its Ola, Arkansas sawmill (the Ola Mill) from federal sources (the Ouachita and Ozark National Forests). Any future decline in the availability of timber from federally owned lands will require that the Company, in order to supply the
Ola Mill, rely more heavily on harvests from the Companys timberlands (including harvests from timberlands acquired in the future to the extent that suitable opportunities arise) and on the acquisition of timber from other sources, such as
private timber owners. The Companys Waldo, Arkansas sawmill does not currently process any timber acquired from federal sources.

Limitations on the Companys Ability to Harvest Timber

Revenues from the Companys future operations will
depend to a significant extent on its ability to harvest timber pursuant to its harvest plans from its 437,700 acres of timberlands (the Timberlands). Harvesting of the Timberlands may be affected by various natural factors, including
damage by fire, insect infestation, disease, prolonged drought, severe weather conditions including ice storms and other causes. The effects of such natural disasters may be particularly damaging to young timber. To the extent possible, the Company
implements measures to limit the risk of damage from such natural causes. The Company is a participant with state agencies and other timberland owners in cooperative fire fighting and fire surveillance programs. In addition, the Timberlands
extensive system of access roads and the physical separation of various tracts provide some protection against fire damage. Nonetheless, one or more major fires on the Timberlands could adversely affect Deltics operating results. In addition,
the Timberlands may also be affected by insect infestation, particularly by the southern pine beetle, and disease. Additionally, the Timberlands may be affected by severe weather conditions, especially ice storms, tornados, and heavy winds. Although
damage from such natural causes usually is localized and affects only a limited percentage of the timber, there can be no assurance that any damage affecting the Timberlands will, in fact, be so limited. As is typical in the forest products
industry, the Company does not maintain insurance coverage with respect to damage to the Timberlands. The Company does, however, maintain insurance for loss of logs due to fire and other occurrences following their receipt at the Companys
sawmills.

##### Table of Contents

Operation of Sawmills

The Companys sawmills are located at Ola in central Arkansas and Waldo in southern Arkansas. The operations of the sawmills are dependent on various
factors and there can be no assurance that the Company will be able to continue such operations at current levels of production or that suspension of such operations may not be required in the future. One such factor is the ability of the Company to
procure sufficient logs at favorable prices. The Company obtains logs for its sawmills from the Timberlands, other private sources, and federal lands. As discussed above, prices for logs are cyclical and affected primarily by demand for lumber and
other products produced from logs. Another such factor is the ability of the Company to find an outlet for the large volume of residual wood products that result from the milling process. The Company currently markets such products to third parties
for the production of paper and other uses. The Company sells a significant portion of its residual wood chips to Del-Tin Fiber L.L.C. (Del-Tin), a joint venture medium density fiberboard plant near El Dorado, Arkansas, in which the
Company owns a 50-percent interest. In addition, the continued operation of the sawmills is subject generally to the risk of business interruption in the event of a fire or other natural disaster, regulatory actions, or other causes. The Company
mitigates this risk through the procurement of casualty and business interruption insurance.

Del-Tin Fiber

Deltic owns 50 percent of the membership interest of Del-Tin Fiber, a joint venture to manufacture and market MDF. The Del-Tin Fiber plant is located near
El Dorado, Arkansas. Construction of the plant was completed, and initial production began, in 1998. From the time production began at Del-Tin Fiber until the fourth quarter of 2003, both operating and financial performance were below the
expectations established at the time that the decision to construct the plant was made. Contributions to Del-Tin Fiber by the Company through the third quarter of 2003 amounted to $60.7 million. The operating and financial performance of the joint
venture improved significantly in 2004 and 2005 when compared to prior years. These advances were the result of price improvements in the MDF market and the Companys utilization of its management resources to work with Del-Tins
management and the joint-venture partner to improve operating performance at the plant. As a result, the impact of Del-Tin Fiber on the Companys results of operations and cash flows was significantly reduced during the years of 2004 and 2005.
Although the Company remains focused on the efficient operations of the facility, changes in MDF prices or disruptions in manufacturing operations at the plant could impact the Companys results of operations and cash flows in future periods,
as well as Deltics ability to exit the MDF business if desired in the future.

Competition

The forest products industry is highly competitive in terms of price and quality. Many of the Companys competitors are fully integrated companies
with substantially greater financial and operating resources than the Company. The products of the Company are subject to increasing competition from a variety of non-wood and engineered wood products. In addition, the Company is subject to a
potential increase in competition from lumber products and logs imported from foreign sources. Any significant increase in competitive pressures from substitute products or other domestic or foreign suppliers could have a material adverse effect on
the Company.

Federal and State Environmental Regulations

The Company is subject to extensive and changing federal, state, and local environmental laws and regulations relating to the protection of human health
and the environment, the provisions and enforcement of which are expected to become more stringent in the future. The Company has made and will continue to make non-material expenditures to comply with such provisions. Based on currently available
information, including the fact that the Company is not presently aware of any facts that indicate that the Company will be required to incur any material costs relating to environmental matters, the Company believes that environmental regulation
will not materially adversely effect the Company, but there can be no assurances that environmental regulation will not have a material adverse effect on the financial condition, results of operations, or liquidity of the Company in the future.

##### Table of Contents

Geographic Concentration of Real Estate Development

The Companys real estate development projects are located in central Arkansas, specifically in, and west of, Little Rock, Arkansas, and in Hot
Springs, Arkansas. Accordingly, the Companys real estate operations are particularly vulnerable to any economic downturns or other adverse events that may occur in this region and to competition from nearby residential housing developments.
The Companys results of operations may be affected by the cyclicality of the homebuilding and real estate industries generally. Factors include changes in general and local economic conditions, such as employment levels, consumer confidence
and income, housing demand, availability of financing and interest rates, and changes in government regulation regarding the environment, zoning, real estate taxes, and other local government fees.

Reliance on Key Personnel

The
Company believes that its continued success will depend in large part on its ability to attract and retain highly skilled and qualified personnel. The Company offers management incentives in a manner that is directly linked to the Companys
performance, which the Company believes will facilitate the attraction, retention, and motivation of highly skilled and qualified personnel. In this regard, the Company has taken steps to retain its key personnel, including the provision of
competitive employee benefit programs. Although the Company will seek to employ qualified individuals in the event that officers or other key employees of the Company cease to be associated with the Company, there can be no assurance that such
individuals could be engaged by the Company.

Dividend Policy

The Company currently intends to pay modest quarterly cash dividends. However, the Company anticipates that future earnings will for the most part be used
to support operations and finance growth of the business. The payment of any dividends will be at the discretion of the Companys Board of Directors (the Company Board). The declaration of dividends and the amount thereof will
depend on a number of factors, including the Companys financial condition, capital requirements, funds from operations, future business prospects, and such other factors as the Company Board may deem relevant, and no assurance can be given as
to the timing or amount of any dividend payments.

Anti-Takeover Effects of Certain Statutory, Charter, Bylaw and Contractual
Provisions

Several provisions of the Companys Certificate of Incorporation and Bylaws and of the Delaware General Corporation Law
could discourage potential acquisition proposals and could deter or delay unsolicited changes in control of the Company, including provisions creating a classified Board of Directors, limiting the stockholders powers to remove directors, and
prohibiting the taking of action by written consent in lieu of a stockholders meeting. The preferred stock purchase rights attached to the Companys common stock could have similar anti-takeover effects. In addition, the Companys
Board has the authority, without further action by the stockholders, to fix the rights and preferences of and to issue preferred stock. The issuance of preferred stock could adversely affect the voting power of the owners of Companys common
stock, including the loss of voting control to others. Transactions subject to these restrictions will include, among other things, the liquidation of the Company, the merger, consolidation or other combination or affiliation of the Company with
another company, discontinuance of or material change in the conduct of a material portion of its businesses independently and with its own employees, redemption or other reacquisition of Companys common stock, and the sale, distribution, or
other disposition of assets of the Company out of the ordinary course of business.

These provisions and others that could be adopted in
the future could discourage unsolicited acquisition proposals or delay or prevent changes in control or management of the Company, including transactions in which stockholders might otherwise receive a premium for their shares over then current
market prices. In addition, these provisions could limit the ability of stockholders to approve transactions that they may deem to be in their best interests.

Item 7. Managements Discussion and Analysis of Financial Condition and Results of Operations

Introduction

Deltic Timber Corporation (Deltic or the Company) is a natural resources company engaged primarily in the
growing and harvesting of timber and the manufacture and marketing of lumber. Deltic owns approximately 437,700 acres of timberland, primarily in Arkansas and north Louisiana. The Companys sawmill operations are located at Ola in central
Arkansas (the Ola Mill) and at Waldo in south Arkansas (the Waldo Mill). In addition to its timber and lumber operations, the Company is engaged in real estate development in central Arkansas. The Company also holds a 50
percent interest in Del-Tin Fiber L.L.C. (Del-Tin Fiber), a joint venture to manufacture and market medium density fiberboard (MDF). Deltic is a calendar-year company for both financial and income tax reporting.

The Company is organized into four segments: (1) Woodlands, which manages the Companys timberlands; (2) Mills, which consists of
Deltics two sawmills that manufacture a variety of lumber products; (3) Real Estate, which includes the Companys real estate developments and a related country club operation; and (4) Corporate, which consists of executive
management, accounting, information systems, human resources, purchasing, treasury, income tax, and legal staff functions that provide support services to the operating business units. (The Company currently does not allocate the cost of maintaining
these support functions to its operating units.)

The Companys timberlands consist primarily of Southern Pine, known in the industry
as a type of softwood. Deltic considers its timberlands to be the Companys most valuable asset and the harvest of stumpage to be its most significant source of income; accordingly, Deltic actively manages its timberlands in order
to increase productivity and maximize the long-term value of these timber assets. The Company harvests timber from the timberlands in accordance with its harvest plans and sells such timber in the domestic market or converts it to lumber in its
sawmills. Stumpage supplied to the Companys sawmills is transferred at prices that approximate market. The Company implemented a timberland acquisition program in late 1996, and this ongoing program has enabled the Company, when desired, to
increase harvest levels, while expanding its timber inventory. Thus far, the Company has focused its acquisition program on timberland in its current operating area. The Company also initiated a program in 1999 to identify for possible sale
non-strategic timberland and higher and better use lands. Whenever possible, the Company structures such sales to qualify as tax-deferred like-kind exchanges.

The Companys two sawmills employ modern technology in order to improve efficiency, reduce labor costs, maximize utilization of the timber resource, and maintain high standards for production quality with safety
being one of its highest priorities. In addition, each mill is strategically located near significant portions of the timberlands. The mills produce a variety of lumber products, including dimension lumber, boards, timbers, decking, and secondary
manufacturing products, such as finger-jointed studs. These lumber products are sold primarily to wholesale distributors, lumber treaters, and truss manufacturers in the South and Midwest and are used mainly in residential construction, roof
trusses, and laminated beams.

The Companys real estate operations were started in 1985 to add value to former timberland
strategically located in the growth corridor of west Little Rock, Arkansas. Since that time, the Company has been developing Chenal Valley, an approximately 5,000-acre upscale planned community. The property is being developed in stages, and real
estate sales to-date have consisted primarily of residential lots, which are sold to builders or individuals, and commercial sites. In addition to Chenal Valley, Deltic has developed Chenal Downs, a 400-acre development located just outside Chenal
Valley, and Red Oak Ridge, an 800-acre development in Hot Springs, Arkansas. Also, the Company disclosed in 2004 plans for The Ridges at Nowlin Creek, an upscale, 1,170-acre, low-impact residential development located just west of Chenal Valley,
that will feature state-of-the-art best-management practices to protect water quality in response to its site adjacent to Lake Maumelle (see the Executive Overview section for further discussion of The Ridges at Nowlin Creek).

The Del-Tin Fiber plant is located near El Dorado, Arkansas. Construction of the plant was completed, and
initial production began in 1998. The plant is designed to have a rated annual capacity of 150 million square feet (MMSF) on a 3/4 inch basis, making it one of the largest plants of its type in the world. MDF, which is used
primarily in the furniture, flooring, and molding industries, is manufactured from sawmill residuals such as chips, shavings, and sawdust, held together by an adhesive bond.

Executive Overview

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. Given its relative size and the nature of most commodity markets, the Company has
little or no control over pricing levels for its wood products. Therefore, the Company will continually seek to wring controllable costs and expenses from its manufacturing processes. 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.

Significant
accomplishments during the year of 2005 include: (1) Deltics Mills segment achieved record finished lumber production and sales volume levels; (2) the Companys Real Estate operations reported its second best level of
residential sales activity, as well as reporting 5.7 acres of commercial real estate sales at a record average commercial sales price per acre; (3) Deltics Woodlands segment realized its highest average pine sawtimber price in five years;
and (4) the Company replaced its existing $125 million revolving credit agreement with a new $260 million revolving credit agreement.

The Woodlands segment continued its trend of steady contributions to earnings during the current year. The 2005 pine sawtimber harvest volume of 581,000 tons was virtually unchanged when compared to 2004s volume of 578,000. However,
the segments 2005 operating profit was 14 percent higher than 2004, due primarily to a $5 per ton increase in the average pine sawtimber sales price, from $40 per ton in 2004 to $45 per ton in 2005. The segments geographic operating area
experienced a higher-than-normal level of rainfall during the latter half of 2004, which hindered logging operations within the industry, resulting in area mills depleting their existing log inventories. Consequently, the demand and corresponding
price for pine sawtimber logs within the region increased during the first half of 2005. During the third quarter, area sawmills largely recovered from their over-depletion of log inventories, however, high lumber production levels continued the
strong demand, and corresponding price, for pine sawtimber logs. Excluding the effects of weather conditions, if area sawmills continue their current lumber production rates within the segments operating region, Deltic expects average pine
sawtimber prices to continue at 2005s level into 2006.

While lumber production levels within a region can influence pine sawtimber
prices, lumber prices typically do not. Over the long-term, there is a fundamental correlation between the level of lumber prices and pine sawtimber prices. However, in the short-term, the geographical size differential between the lumber and pine
sawtimber markets results in the two acting somewhat independently of each other. Pine sawtimber markets operate primarily within local or regional areas with sales being mainly to sawmills. These mills are subject to a relatively fixed level of
demand for raw materials that is driven by the facilities required production levels. Increases in pricing levels within the lumber market typically do not have a significant effect on the existing demand for raw materials in the short-term,
resulting in little impact to pine sawtimber prices. This trend would typically also be true in the short-term, during times of a depressed lumber market.

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. The 2005
harvest level allowed the Company to manage its forests on a sustainable-yield basis. Deltic incurred no direct impact to its timberland holdings from the hurricanes that struck the Gulf Coast states in 2005. While lumber markets may be affected in
2006 by the possible flood of product from the salvage of downed timber within the Gulf Coast region, the Company does not expect the operations of its Woodlands segment to be directly affected by the aftermath of these hurricanes.

During 2004, Deltic increased the return requirements previously established for the sale of higher and
better use and non-strategic timberland, and accordingly, the Company experienced further reductions in timberland sales activity during 2005. Timberland designated as higher and better use consists of tracts with market values that exceed the
lands worth as a timber growing platform. Deltics approximately 58,000-acre timberland holdings in the expanding westward growth corridor of Little Rock, Arkansas is an example of such land. Non-strategic timberland is composed 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 ancillary values of land ownership, such as revenues from hunting leases, mineral lease bonuses and royalties, or land easements, have historically
provided additional income to Deltics Woodlands segment. Recent advances in technology and increased pricing levels 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, ranging in depth from 1,300 feet to 6,500 feet, and is spread across multiple Arkansas counties. During 2005, Deltic leased approximately 15,000
net mineral acres under this play to various exploration enterprises and received applicable lease bonus payments and the possibility of future royalty income should production be established. The Company continues to evaluate and process additional
leasing requests regarding its land holdings within the Fayetteville Shale Play. The ultimate benefit to Deltic from these mineral leases remains unknown to the Company and is contingent on the successful extraction and sale of natural gas from the
area.

For the Mills segment, the status of the lumber market and the resulting impact on the Companys commodity softwood lumber
products will continuously impact operating strategies and financial results. U.S. housing starts for 2005 reached their second highest level on record, exceeded only by 1972. This strong housing market, as well as, the 2005 record level of repair
and remodeling activity within the United States continued to be driven by historically low mortgage interest rates and an overall strong U.S. economy. As a result of these factors, Deltic was able to maintain appropriate pricing levels within its
Mills segment. The segments 2005 average lumber sales price was the highest in six years, increasing one percent when compared to 2004. As with any commodity market, the Company expects the historical volatility of lumber prices to continue in
the future. Multiple factors could affect average lumber prices in 2006. While most industry analysts are projecting the strong U.S. housing market to continue into 2006, a slowdown has been predicted for the year when compared to 2005,
predominately from a projected increase in mortgage interest rates. Other factors impacting future lumber prices include projected growth in offshore lumber imports and increases in lumber supply resulting from the salvage of timber downed by the
recent hurricanes in the U.S. Gulf Coast region. Possible positive factors include the anticipated rebuilding efforts following the 2005 hurricanes in the U.S. South and the expected retention of a strong repair and remodeling market. In addition to
these issues, the softwood lumber trade dispute between the U.S. and Canada remained unresolved throughout 2005. The Company, along with other members of the industry, awaits the resolution of this trade dispute, which alone could have a significant
impact on future pricing levels within the U.S. lumber market.

Since commodity-based markets rarely benefit from real price growth,
after inflation, Deltic has concentrated managements attention, in regard to its manufacturing operations, on improving sales realizations through product and customer mix enhancements and improving production efficiencies and the cost
structure at its lumber mills. These production efficiency improvements are largely dependent upon increases in hourly production rates and mill uptime percentage. Deltics Mills segment reported record volumes of finished lumber production and
sales for the year of 2005. Furthermore, the segments 2005 average sawmill production per hour and planer mill production per hour both improved seven percent when compared to 2004. Despite these achievements, the Mills segments 2005
operating income declined five percent when compared to 2004, due primarily to increased raw material log cost.

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. Continued low mortgage
interest rates in 2005 aided overall demand for residential lots in Chenal Valley, the largest of the Companys three active developments, as evidenced by Chenal Valleys 230 residential lot closings in 2005. However, during the second
half of the year, new residential construction in the west Little Rock speculative home market began to show signs of the impact of higher interest rates,

energy cost, and building material cost. As a result, the Companys 2005 third and fourth quarter neighborhood offerings in Chenal Valley, experienced a
decline in commitments from area builders. The Company believes the recent rise in building costs and mortgage interest rates may have an effect on its Real Estate segment in 2006 by pushing annual residential lot sales closer to pre-2004 levels.
Lot development for 2006 will be market driven and may range from 75 to 230 lots. Ultimately, the impact to Deltics overall real estate business model from moderate fluctuations in the annual volumes of residential lot sales is deemed minimal
in light of the Companys continued focus on the long-term financial returns from the ultimate build-out of the Chenal Valley development. In Deltics other two active developments, Red Oak Ridge and Chenal Downs, a total of 19 lots were
sold, leaving 87 developed lots in Red Oak Ridge and 18 in Chenal Downs uncommitted as of year-end 2005. While Chenal Downs is fully developed, Deltic plans to develop additional lots within Red Oak Ridge subsequent to 2006. Actual future annual lot
development levels will be dependent upon the demand for the Companys residential lots.

The Real Estate segments average sales
price for residential lots sold in 2005 of $78,600 increased eight percent when compared to 2004. Average price for a reporting period is largely dependent on the mix of lots sold in that period. Deltics lot development plans provide for a mix
of lot offerings that represent all real estate market segments for a planned community. Neighborhoods adjoining Chenal Country Clubs second 18-hole, championship golf course designed by Robert Trent Jones, Jr. represent the highest priced
market segment in the Chenal Valley development. Average prices for non-golf course lots are lower and vary between neighborhoods depending on other factors such as lot size and location. The mix of lot offerings for any given year will be driven by
lot inventory and expected demand.

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 its large 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, and proven, 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, on September 19, 2005, the utility filed its petition in the Circuit Court of Pulaski County, Arkansas, to condemn that portion of the development within the lakes watershed, and deposited $3.8 million as 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. Upon application by Deltic, on October 11, 2005, the funds were transferred into the
Companys bank account. Under Arkansas law, Deltic has the right, and has initiated proceedings, to have a jury determine the true amount of just compensation for the taking of the lands, as well as other damages. The trial of this matter is
scheduled to begin 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. Should the utility determine to pay the final
judgement, the Company will need to further assess the viability of proceeding with development of lots in the developments remaining acreage. (For further discussion, refer to Note 16 to the consolidated financial statements.)

Commercial real estate sales activity is by nature less predictable than residential activity. With the number of residents in Chenal Valley and other
west Little Rock areas growing steadily, and momentum created from previous sales of commercial acreage in the development, interest in the Companys remaining commercial acreage is increasing. The volume of commercial sales totaled 5.7 acres
in 2005 versus 4.2 acres in 2004. However, the average sales price per acre rose significantly from $226,200 in 2004, to $945,800 for 2005. Future pricing trends for commercial real estate sales are difficult to predict and are influenced by
multiple factors, which include intended use of the site, motivation of the purchaser, and property location and access. No commercial acreage is included in the Chenal Downs or The Ridges at Nowlin Creek developments. Red Oak Ridge is planned to
include approximately 80 acres of commercial property. The Company will begin to develop and offer commercial sites as this developments population density increases.

On April 6, 2004, RED Development LLC announced plans for The Promenade at Chenal, a 48-acre, open-air, lifestyle shopping center.
Deltics sales contract with RED Development regarding this site as amended was scheduled to close before the end of 2005. However, as is the inherent unpredictable nature of commercial real estate sales, the contract has been extended and is
now scheduled to close in 2006. Some extensions of similar contracts in the past have been followed by the termination of the commercial sale. The Company continues to assist Red Development in its study of the site.

Operating results for Del-Tin Fiber are affected primarily by the overall MDF market and plant operating performance. Chinas MDF industry and
product exports continue to grow rapidly as that country ended 2005 as the largest producer of MDF in the world. The U.S. MDF market was impacted by high product imports and high U.S. MDF production until 2004 when consumer demand outpaced
production and provided relief from depressed pricing levels. Overall, this trend continued into 2005 as annual average MDF prices within the industry were comparable to 2004. However, in addition to increases in imports during 2005, the U.S. MDF
market experienced further displacement of product demand as segments of the U.S. furniture manufacturing industry, a primary purchaser of MDF, continued their relocations to the Far East. These factors combined with continued robust North American
MDF production in 2005, resulted in the industry experiencing a slight reduction in pricing levels during the second half of the year. Multiple factors could affect MDF prices in 2006. In addition to the factors that impacted 2005, continued higher
interest cost could further reduce consumption from housing starts and remodeling construction.

Operationally, Del-Tin Fiber continued to
make advances during 2005. The plants management remained focused on raising the plants uptime percentage to be at or above the industry average and improving the plants cost structure. However, these operating advancements were
overshadowed by a temporary production curtailment caused by a fire sustained at the plant during the first quarter of 2005 and increased petroleum-based resin raw material costs. The impact of the unscheduled downtime caused by the fire caused a
reduction in the planned 2005 total production volume. The plant returned to profitability during the second quarter of 2005, and finished the year at a financial break-even. Future efforts are being concentrated on further improving productivity
levels and plant efficiencies and making additional reductions in the plants manufacturing cost per thousand square feet (MSF).

Significant Events

On September 9, 2005, the Company completed negotiation with SunTrust Bank and other banks
for an unsecured and committed revolving credit facility totaling $260 million. The facility also contains a $50 million letter of credit feature. The agreement, which will expire on September 9, 2010, replaced the existing facility that was
scheduled to expire July 15, 2007. The funds available through this agreement will enable Deltic to take full advantage of value-adding growth opportunities as they present themselves.

On August 26, 2004, Del-Tin Fiber successfully 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 pursuant to which, $60 million of its $89 million industrial revenue bonds were redeemed. 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. This refinancing resulted in more favorable credit terms for the joint venture, the most notable of which was the removal of the remaining required bond sinking fund payments of
$55.9 million due in 2005 under the prior debt facility. (For additional information about the Companys investment in Del-Tin Fiber, refer to Note 3 to the consolidated financial statements.)

From the time production began at Del-Tin Fiber in 1998 until the fourth quarter of 2003, both operating and financial performance were below the
expectations established at the time that the decision to construct the plant was made. As a result, on April 25, 2002, Deltic announced that Banc One Capital Markets, Inc. had been retained as financial advisor to assist in the evaluation of
strategic alternatives for the Companys investment in Del-Tin Fiber. Subsequently, Deltics management and Board of Directors completed its review of these strategic alternatives and announced the Company intended to exit the MDF

business upon the earliest, reasonable opportunity provided by the market. As a result of this decision, the Companys evaluation of possible impairment
of the carrying value of its investment in the joint-venture was based primarily upon the estimated cash flows from a sale of the Companys interest during 2003 and resulted in a determination that the Companys investment was impaired as
of December 31, 2002. The investment was written off, to zero, and the write-off amounted to $18.7 million before income taxes.

Due
to the Companys commitment to fund its share of any of the facilitys operating working capital needs until the facility was able to consistently generate sufficient funds to meet its cash requirements or Deltics ownership was sold,
the Company recognized equity in Del-Tin Fiber equal to the extent of these advances during 2003. For the year of 2003, such advances approximated the Companys equity share of losses for the plant; accordingly, the investment in Del-Tin Fiber
at December 31, 2003, was zero. The Company also continued to utilize its management resources to work with Del-Tins management and the joint-venture partner to improve operating performance at the plant. As a result of these
improvements, on December 11, 2003, Deltics Board of Directors revised its intent regarding the Companys investment in Del-Tin Fiber and ceased efforts to sell the Companys interest in the joint venture, while continuing to
focus on improving operating and financial results of the plant. Due to this decision, the 2003 evaluation of fair value for the investment was based primarily upon the future net cash flows from Del-Tin Fibers operations over the remaining
life of the plant. The estimated fair value from this evaluation indicated that no impairment existed as of December 31, 2003. In 2004, the Company began recording its equity share of the operating results of the joint venture.

Consolidated

The $3.4 million increase in net income during 2005 was the result of improved operating results for the Companys Woodlands and Real Estate segments combined with a non-cash income tax benefit of $1.7 million
created by the impact of the reversal of an estimated valuation allowance previously applied to portions of Deltics deferred tax assets. These items were partially offset by an increase in general and administrative expenses. Deltic realized
$168.4 million in total net sales in 2005, a record level for the Company. The $2.9 million increase in net income during 2004 was the result of improved operating results for the Companys Mills segment combined with improved financial results
from Del-Tin Fiber, partially offset by the absence of significant sales of both commercial real estate property and timberland, which were present in 2003. General and administrative expenses also increased in 2004 when compared to 2003.

Operating income for 2005 increased 13 percent when compared to 2004. The Woodlands segment increased $2.8 million due primarily to an
increase in the average per-ton pine sawtimber price. Mills segment operating results decreased $.3 million despite increases in both average lumber sales price and lumber sales volume, due primarily to increased raw material costs. Real Estate
operating income increased $2.7 million resulting from 2005 benefiting from the sales of higher margin residential lots and commercial acreage, partially offset by a decrease in sales of undeveloped real estate acreage.

Operating income for 2004 remained relatively flat, decreasing $.8 million compared to 2003. The Woodlands segment decreased $5.2 million due primarily
to a decrease in sales of both timberland for higher and better use and non-strategic timberland combined with the planned slight reduction in the pine sawtimber harvest level. Mills segment operating results improved $12.2 million as a result of a
$55 per thousand board feet (MBF) rise in average lumber sales price and a four percent increase in lumber sales volume. Real Estate operating income decreased $5.1 million resulting from 2003 benefiting from increased sales of
commercial acreage, partially offset by a record level of residential lot closings and a large sale of undeveloped real estate acreage during 2004.

##### Table of Contents

Total net sales in 2005 increased $4.1 million when compared to 2004. Sales of pine sawtimber increased
$2.7 million, or twelve percent, from 2004, attributable to the increase in the average per-ton pine sawtimber price. Sales of pine pulpwood increased $1.1 million due to an increase in harvest level and a higher per-ton average sales price. During
2005, sales of timberland decreased by $1.2 million from 2004, due to a general reduction in the number of acres sold. Other items attributing to the increase in total net sales was a $.6 million increase in freight revenue and a $.4 million
increase in lease revenue.

Total net sales in 2004 decreased $7.2 million when compared to 2003. Sales of pine sawtimber decreased $1.5
million, or 6 percent, from 2003, attributable entirely to the decrease in sales volume which was in accordance with the Companys planned slight reduction in harvest. Sales of hardwood sawtimber decreased $.5 million due to a reduction in
harvest level, partially offset by a higher average sales price. During 2004, sales of timberland decreased by $6.7 million from 2003, due to a general reduction in the number of acres sold and to 2003 benefiting from the sale of a choice, 275-acre,
higher and better use tract from Deltics approximately 58,000-acre timberland holdings in the Highway 10 growth corridor just west of the Chenal Valley real estate development.

The Woodlands segments operating income for 2005 was $2.8 million more than 2004 due to the increase in net sales and a reduction in the cost of
timberland sales, partially offset by increases in cull timber removal expense, freight expense, and cost of fee timber harvested. Operating income for 2004 was $5.2 million less than 2003 due to the reduction in net sales, partially offset by the
corresponding reductions in the cost of timberland sales and the cost of fee timber harvested.

Mills

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



|                                |  |      |       |      |      |      |

|Sales price (per MBF)           |  | $    | 369   |      | 365  |      | 310 

Total net sales increased 24 percent in both 2005 and 2004 when compared to the prior year. Lumber
sales increased in both years due to a higher sales volume and a higher average sales price. Revenue from sales of residual by-products increased due mainly to increased lumber production volumes in 2005 and 2004. Freight revenue increased during
both years due to increased lumber sales volume.

The reduction in the Mills segments operating income for 2005, despite the increase
in net sales, was due primarily to increased raw material log costs. The improvement in operating income between 2004 and 2003 was the result of the increase in net sales.

Total net sales increased $1.9 million in 2005, or six percent, due to increased commercial real
estate sales, partially offset by decreased revenues from the sale of residential lots and undeveloped acreage. While the number of residential lots sold decreased, the average price per lot increased due to sales mix. The 2005 sales volume of
commercial acreage was a slight increase over 2004; however, the 2005 average price per acre increased significantly due to the locations of the commercial sites sold. Chenal Country Club, Inc. produced net sales of $6.4 million for 2005, an
increase of $.5 million.

Total net sales decreased $2.7 million in 2004, or 8 percent. The number of residential lots sold increased by 94
lots; however, due to the sales mix of the lots sold, the segment incurred a 6 percent decrease in average sales price per lot. There were limited commercial real estate sales of only 4 acres during 2004, resulting in a decrease of $11.6 million in
net commercial sales revenue. However, the sale of 94 acres of undeveloped real estate property was completed, which resulted in net sales of $2.6 million, compared to no undeveloped real estate sales in 2003. Chenal Country Club, Inc. produced net
sales of $5.9 million for 2004, an increase of $.7 million.

The changes in the Real Estate segments operating income were due
primarily to the same factors impacting net sales.

Corporate

The increase in operating expense for Corporate functions of $1.1 million in 2005 was due primarily to, increased incentive plan expenses due to improved
financial results, and increased charitable contributions, partially offset by higher 2004 retirement plan expenses not present in 2005 related to separated employees.

The increase in operating expense for Corporate functions of $3.2 million in 2004 was due primarily to higher retirement plan expenses related to separated employees, increased incentive plan expenses due to improved
financial results, and increased professional fees relating to the Companys compliance with Section 404 of the Sarbanes-Oxley Act of 2002.

Eliminations

Intersegment sales of timber from Deltics Woodlands segment to the Mills segment
were $20.7 million in 2005, $18.0 million in 2004, and $15.8 million in 2003. The $2.7 million increase during 2005 was due primarily to a higher average transfer price. There were no intersegment timberland sales commissions in 2005 or 2004,
compared to $.3 million in 2003.

Equity in Del-Tin Fiber

For the year ended December 31, 2005, equity in Del-Tin Fiber recorded by the Company was zero compared to 2004s equity income of $.4 million.

##### Table of Contents

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



|                                |  |      |       |      |       |      |

|Net sales (millions of dollars) |  | $    | 56.3  |      | 65.4  |      | 48.7 
|Finished production (MMSF)      |  |      | 140.9 |      | 148.3 |      | 132.7
|Board sales (MMSF)              |  |      | 139.8 |      | 150.4 |      | 131.2
|Sales price (per MSF)           |  | $    | 403   |      | 398   |      | 339  

Average sales price for 2005 increased $5 per MSF when compared to 2004 due to favorable market
conditions in addition to a continued change in product mix to include a greater percentage of thin board and an increase in premium grade production. During the first quarter of 2005, the facilitys operations were hindered by a temporary
production curtailment caused by a fire sustained at the plant. The effect of the first quarter curtailment was decreases in both finished production and sales volumes for the plant. Manufacturing cost per MSF sold for 2005 was up two percent due
primarily to decreased production volume and increased petroleum-based resin raw material costs.

Average sales price for 2004 increased
$59 per MSF when compared to 2003 due to favorable market conditions, in addition to a continued change in product mix to include a greater percentage of thin board and an increase in premium grade production. Manufacturing cost per MSF sold for
2004 was down 3 percent due primarily to the lowering of certain variable costs of manufacturing and the spreading of the plants fixed cost to the increased production volume.

Interest Income/Expense

When
compared to the prior year, interest expense for 2005 and 2004 decreased $.2 million and $.9 million respectively due primarily to reduction of long-term debt.

Income Taxes

The effective income tax rate was 30 percent, 38 percent, and 37 percent in 2005, 2004,
and 2003, respectively. The decrease in the effective income tax rate for 2005 was due primarily to the impact of an income tax benefit created by a reversal of the estimated valuation allowance related to accumulated state net operating loss
carryforwards. Based on current projections of increased future taxable income, it is now more likely than not that the future benefits of these state net operating losses will be utilized in their entirety. Before recording the reduction in the
valuation allowance, the Companys effective income tax rate for 2005 was 38 percent. The effective rate increase in 2004 was due primarily to higher effective rates for state income taxes, partially offset by changes in the valuation
allowance.

Liquidity and Capital Resources

Cash Flows and Capital Expenditures

Net cash provided by operating activities totaled $43.1 million
for the year ended December 31, 2005, which compares to $42.1 million for 2004 and $44.2 million for 2003. Changes in operating working capital, other than cash and cash equivalents, provided cash of $1.2 million in 2005, $.9 million in 2004,
and $.7 million in 2003. Net cash provided by other operating activities included changes in long-term deferred mineral lease bonus revenue of $1.3 million in 2005, and zero in 2004 and 2003. Also included in net cash provided by other operating
activities in 2005 was $3.8 million received in connection with the condemnation of portions of the Companys planned real estate development, The Ridges at Nowlin Creek. The Companys accompanying Consolidated Statements of
Cash Flows identify other differences between income and cash provided by operating activities for each reported year.

Woodlands capital expenditures included timberland acquisitions of approximately 1,800 acres at a
cost of $5.4 million in 2005, approximately 4,200 acres at a cost of $5.1 million in 2004, and approximately 7,300 acres at a cost of $10.9 million in 2003. Reforestation site preparation and planting required expenditures of $ 1.3 million in
2005, $1.4 million in 2004, and $1.3 million in 2003, and were the result of expansion of the Companys planting program due to recent acquisitions of timberland and to final harvests of mature stands, necessitating regeneration.

During 2005, significant capital expenditures for the Mills segment included $6 million to add an additional boiler and upgrade the lumber drying kilns
at the Waldo Mill to improve sales realizations, while reducing costs, and to increase the mills lumber drying capacity. At the Ola Mill a primary breakdown redesign and rebuild of the sawmill processing equipment was performed at a cost of
$1.3 million which focused primarily on improving the handling system used to feed logs into the sawmill and overall flow of green lumber through the sawmill. Also at the Ola Mill, $.5 million was expended to complete the installation of an
automated lumber grading system. During 2004, $1 million was expended at the Waldo Mill for an automated lumber grading system and $.7 million for the initial phase of the boiler and drying kilns project. At the Ola Mill, $.6 million was expended
toward the installation of the automated lumber grading system there. During 2003, $1.3 million was expended to install a second log debarker at the Waldo Mill in order to increase production capacity. At the Ola Mill, $.6 million was expended to
install a J-hook sorter system.

Capital expenditures for Real Estate operations related to the cost of residential lot development totaled
$9.5 million in 2005, $7.6 million in 2004, and $5.4 million in 2003. Land acquisitions required $.7 million in 2004, with no such expenditures in 2005 or 2003. Infrastructure construction required $.3 million in 2005, $.1 million in 2004, with no
such expenditures in 2003. Expenditures related to golf operations at the two courses at Chenal Country Club totaled $.3 million in 2005 for course maintenance equipment and golf carts, compared to $.5 million in 2004 and $.3 million in 2003. In
addition, $1.7 million was expended in 2005 for the construction of a limited number of speculative homes within the Companys Red Oak Ridge development located in Hot Springs, Arkansas, with no such expenditures in 2004 or 2003. Other
expenditures were primarily for various amenity and infrastructure improvements.

Deltic had commitments of $15 million for capital
projects in progress at December 31, 2005. This total commitment includes $.3 million for reforestation site preparation and road construction and $1.5 million for completion of various projects at both the Ola Mill and Waldo Mill. Also, $13.1
million are committed relating to residential lot and commercial site development and amenity improvements at the Companys real estate developments, including $7.4 million for completion of a renovation project at Chenal County Club.

The net change in purchased stumpage inventory provided cash of $3.8 million in 2005 and $2.6 million in 2004, but required cash of $.4
million in 2003. Advances to Del-Tin Fiber by the Company amounted to $4.8 million, $1.6 million, $9 million, in 2005, 2004, and 2003, respectively. The Company received cash distributions from Del-Tin Fiber of $3.8 million in 2005 and $1.4 million
in 2004, with no such distributions in 2003. At the end of 2002, $.4 million of proceeds from sales of appreciated timberland parcels were deposited and held by a trustee to be used to acquire timberland designated as replacement
property for income tax purposes, as required for tax-deferred exchanges. These funds were received from the trustee in the first quarter of 2003 and utilized to finance a portion of timberlands that were acquired during the period.

##### Table of Contents

The $4.6 million received for timberland sold during 2003 was held by the trustee at December 31, 2003, while the Company identified potential
timberlands to acquire in order to qualify these sales as a tax-deferred exchange. In 2004, these proceeds were received from the trustee and utilized to acquire timberlands as required. No timberland sales involving tax-deferred exchanges occurred
in 2005. Initiation fees received from members joining Chenal Country Club, which are accounted for as a reduction in the cost basis of the club rather than net sales, amounted to $1.1 million in 2005, $1.2 million in 2004, and $1.3 million in 2003.

During 2005, Deltic borrowed $43.5 million and repaid $54.7 million under its revolving credit facility. During 2004, Deltic borrowed
$29.7 million and repaid $59 million under its revolving credit facility, in addition to making repayments of owner-financed debt of $.1 million. In 2003, borrowings under available credit facilities provided $37 million, with repayments amounting
to $38.1 million.

The Company purchased no treasury stock in 2005. Purchases of treasury shares in 2004 were conducted through non-cash
transactions. Purchases of treasury stock required cash of $.4 million in 2003. The decrease in bank overdraft was $.9 million in 2003, bringing the overdraft to zero at December 31, 2003. Cash required to pay common stock dividends totaled
$3.4 million in 2005 and $3 million in both 2004 and 2002. Proceeds from stock option exercises amounted to $1.9 million, $5.2 million, and $1.6 million in 2005, 2004, and 2003, respectively. Costs of $.7 million related Deltics recent
revolving credit facility were paid in 2005. Costs of $.5 million related to extension of Deltics existing revolving credit facility were paid in 2003.

Financial Condition

Working capital at year-end totaled $7 million in 2005 and $6.5 million in 2004.
Deltics working capital ratio at December 31, 2005, was 1.57 to 1, compared to 1.73 to 1 at the end of 2004. Cash and cash equivalents at the end of 2005 were $1.6 million compared to $.9 million at the end of 2004. During 2005, total
indebtedness of the Company decreased $11.2 million to $74.5 million at year-end. Deltics long-term debt to stockholders equity ratio was .376 to 1 at December 31, 2005 compared to .466 to 1 at the end of 2004.

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 residential and/or commercial properties at Chenal Valley, Red Oak Ridge and the currently suspended Ridges at Nowlin Creek.

To facilitate these growth plans, the Company has an agreement with a group of banks which provides an unsecured, committed revolving credit facility
totaling $260 million, inclusive of a $50 million letter of credit feature. The agreement will expire on September 9, 2010. As of December 31, 2005, $253.4 million was available in excess of all borrowings outstanding under or supported by
the facility. The credit agreement contains restrictive covenants, including limitations on the incurrence of debt and requirements to maintain certain financial ratios. (For additional information about the Companys current financing
arrangements, refer to Note 6 to the consolidated financial statements.)

In December 2000, the Companys Board of Directors
authorized a stock repurchase program of up to $10 million of Deltic common stock. As of December 31, 2005, the Company had 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 were purchased under this program during 2005. 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

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, that
began 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 ($26.1 million at December 31, 2005) of Del-Tins obligations under its credit agreement.

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 December 31, 2005, Deltics remaining liability regarding the guarantee was $2.6 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. In 2004 and 2003, the Company
incurred additional net periodic expense related to its defined benefit retirement plans resulting from enhanced retirement benefits granted to certain employees upon retirement. Deltic does not view these enhanced retirement benefits as a trend
carried forward to years subsequent to 2004. With regards to all of the Companys employee and retiree benefit plans, Deltic is unaware of any trends, demands, commitments, events or uncertainties that will result in or that are reasonably
likely to result in the Companys liquidity increasing or decreasing in any material way, or which would cause the 2005 reported plan information not to be necessarily indicative of future operating performance or future financial condition.
(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.)

Outlook

Deltics management believes that cash provided from its operations, the remaining amount available under its credit facility, and its ability to
access the credit markets, will be sufficient to meet its expected cash needs and planned expenditures, including those of the Companys continued timberland acquisition and stock repurchase programs, and capital expenditures, for the
foreseeable future.

The preceding discussion of the Companys liquidity and capital resources contains forward-looking
statements which were made in reliance upon the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. Such statements reflect the Companys current expectations and involve risks and uncertainties. Actual results
could differ materially from those included in such forward-looking statements.

Other Matters

Impact of Inflation

General inflation
has not had a significant effect on the Companys operating results during the three years ended December 31, 2005. The Companys timber operations are more significantly impacted by the forces of supply and demand in the southern
United States than by changes in inflation. Lumber manufacturing operations are affected by the supply of lumber available in the North American market and by the demand for lumber by both the North American and foreign export markets. Sales of real
estate are affected by changes in the general economy and long-term interest rates, specifically as such may manifest themselves in the central Arkansas region.

Market Risk

Market risk represents the potential loss resulting from adverse changes in the value of
financial instruments, either derivative or non-derivative, caused by fluctuations in interest rates, foreign exchange rates, commodity prices, and equity security prices. The Company handles market risks in accordance with its established policies;
however, Deltic does not enter into derivatives or other financial instruments for trading or speculative purposes. The Company does, on occasion, consider the need to enter into financial instruments to manage and reduce the impact of changes in
interest rates; however, the Company entered into no such instruments during the three-year period ended December 31, 2005. Deltic held various financial instruments at December 31, 2005 and 2004, consisting of financial assets and
liabilities reported in the Companys Consolidated Balance Sheets and off-balance sheet exposures resulting from contractual debt guarantees and letters of credit issued for the benefit of Deltic, primarily in connection with its purchased
stumpage procurement and real estate operations. (For additional information regarding these financial instruments, refer to the previous tabular summary of the Companys other commercial commitment expirations and to Note 10 to the
consolidated financial statements.)

##### Table of Contents

Interest Rate Risk - The Company is subject to interest rate risk from the utilization of
financial instruments, such as term debt and other borrowings. The fair market value of long-term, fixed-interest rate debt is subject to interest rate risk. Generally, the fair value of fixed-interest rate debt will increase as interest rates fall
and will decrease as interest rates rise. Conversely, for floating rate debt, interest rate changes generally do not affect the instruments fair value, but do impact future earnings and cash flows, assuming other factors are held constant. The
estimated fair values of the Companys long-term debt, including current maturities; contractual guarantees of debt; and letters of credit at December 31, 2005, were $78.1 million, $2.6 million, and $2.7 million, respectively.

A one percentage-point increase in prevailing interest rates would result in decreases in the estimated fair value of long-term debt of $3.6 million
and contractual guarantees of debt of $.2 million, while the fair value of the Companys letters of credit would be unchanged. Fair values were determined using the current rates at which the Company could enter into comparable financial
instruments with similar remaining maturities. The estimated pretax earnings and cash flows impact for 2005 resulting from a one percentage-point increase in interest rates would be approximately $.1 million, holding other variables constant.

Foreign-Exchange Rate Risk - The Company currently has no exposure to foreign-exchange rate risk because all of its financial
instruments are denominated in U.S. dollars.

Commodity Price Risk - The Company has no financial instruments subject to commodity
price risk.

Equity Security Price Risk - None of the Companys financial instruments have potential exposure to equity
security price risk.

The preceding discussion of the Companys estimated fair value of its financial instruments and the sensitivity
analyses resulting from hypothetical changes in interest rates are forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Such statements reflect the Companys current expectations and
involve uncertainties. These forward-looking market risk disclosures are selective in nature and only address the potential impact from financial instruments. They do not include other potential effects which could impact Deltics business as a
result of changes in interest rates, foreign-exchange rates, commodity prices, or equity security prices.

Critical Accounting Policies
and Estimates

The Company has identified seven of its current accounting policies as being, in managements view, critical to the
portrayal of the Companys financial condition and results of operations. Additionally, six of these policies require significant assumptions and/or estimates on the part of management as it pertains to certain factors inherent in the policies.
The Companys senior management has discussed the development and selection of its critical accounting policies and estimates with the Companys Audit Committee. With the exception of the reduction of the Companys deferred tax asset
valuation allowance in 2005 (Refer to Note 8 to the consolidated financial statements), Deltic has not made any material changes to its critical accounting estimates in the last three years. These policies, along with explanations of the key
assumptions and/or estimates considered by management, are described below. (For a listing of all significant accounting policies of the Company, refer to Note 1 to the consolidated financial statements.)



| | 1) | Investment in Real Estate Held for Development and Sale  Real estate held for development and sale is stated at the lower of cost or net realizable value, and includes
direct costs of land and land development and indirect costs, including amenities. Indirect and amenity costs are allocated to individual lots or acreage sold based on relative sales value. Direct costs are allocated on a specific neighborhood
basis, while indirect costs for the Companys four development areas  Chenal Valley, Chenal Downs, Red Oak Ridge, and the currently suspended The Ridges at Nowlin Creek  are allocated to neighborhoods over the entire respective
development area based on relative retail values.

##### Table of Contents

The key factors involved in determining the Investment in Real Estate Held for Development and Sale are:
(1) the treatment of the clubhouse and golf course at Chenal Country Club, the amenity around which the Chenal Valley development is centered, as an amenity rather than an operating fixed asset and (2) the management estimates required to
estimate the future indirect development costs and sales values of the areas of Chenal Valley yet to be developed. Due to accounting for Chenal Country Club as an amenity, the cost of the clubhouse and golf course, including the estimated cost of
planned future improvements, are charged against income as real estate is sold rather than depreciating this cost. This amenity treatment also records the initiation fees received from members joining the club as a reduction in the cost basis of the
club rather than as net sales. In addition, the Companys model for allocating the indirect cost to be expensed against each piece of real estate sold requires management to estimate the future indirect costs to be incurred for the entire
development, primarily infrastructure costs and future improvements at Chenal Country Club (net of estimated future initiation fees to be received), as well as the potential market value of each tract of undeveloped property within the Chenal Valley
development. In determining future indirect development costs, management relies on cost projections for its development plans provided by independent, professional engineering consultants. Independent appraisers are utilized to provide the
potential market value for unsold acreage.



| | 2) | Investment in Del-Tin Fiber Investment in Del-Tin Fiber L.L.C. (Del-Tin Fiber), a 50 percent-owned limited liability company, is carried at cost and is
adjusted for the Companys proportionate share of Del-Tin Fibers undistributed earnings or losses. The Companys equity-method-basis carrying value for its investment in Del-Tin Fiber is evaluated for possible impairment, as
applicable under the requirements of Accounting Principles Board Opinion (APB) 18, The Equity Method of Accounting for Investments in Common Stock. This evaluation as of December 31, 2002, based on the intent of the Companys
Board of Directors to exit the business, resulted in a determination that the Companys investment was impaired as of December 31, 2002, and the carrying amount of the investment was written off, to zero, for the 2002 Consolidated Balance
Sheet. On December 11, 2003, the Companys Board of Directors revised its intent in regard to selling Deltics interest in the joint venture. The resulting evaluation of fair value for the related investment indicated that fair value
exceeded carrying value, which was zero as of December 31, 2003, and the Company resumed recording its equity share of the operating results of Del-Tin Fiber. Likewise, cash advances to the joint venture are recorded as increases in the
Companys investment in the facility, while cash distributions received from the joint venture are reflected as reductions in its investment.

For Deltics investment in Del-Tin Fiber, the key determinations by management are (1) the accounting treatment for this investment under the equity method of accounting rather than as a consolidated
subsidiary since the joint venture is 50 percent owned by both owners, (2) the factors used in evaluating the impairment of the investments carrying value, and (3) the estimate of the fair value of the Companys guarantee of
Del-Tin Fibers credit agreement. Deltic management has determined that there is no control by either company due to having a Board of Managers with equal representation. As such, the assets and liabilities of Del-Tin Fiber are not included in
the amounts reported on the Companys balance sheet for any period. In evaluating the possibility of the existence of an impairment for the Companys carrying value for its investment in Del-Tin Fiber under APB 18, management must estimate
future net cash flows from the possible courses of action available for its investment, such as continuing to maintain or sell its investment, to determine both recoverability of the carrying amount and fair value of the investment. More
specifically, management must determine the possible courses of action and estimate the probability of each potential action, as well as the related future net cash flows. Then, if estimated fair value is less than the carrying amount, management
must determine if this impairment is other than temporary. If so, then an impairment write-down is required. In estimating the fair value of the guarantee of Del-Tin Fibers credit agreement, Deltics management must first assess how the
same debt instrument would have been structured without the guarantees of the joint venture partners, in order to estimate the premium resulting from Deltics guarantee. A range of probabilities of estimated future cash outflows under the
premium

previously determined are then assembled. A probability-weighted present value of the estimated future cash outflows is then calculated. The resulting
balance represents the fair value of the obligation, which is the estimate of the value of assets required currently to settle the liability in the future. (For additional information about the Companys investment in Del-Tin Fiber, refer to
Note 3 to the consolidated financial statements.)



| | 3) | Timber and Timberlands  Timber and timberlands, which includes purchased stumpage inventory and logging facilities, is stated at acquisition cost less cost of fee
timber harvested and accumulated depreciation of logging facilities. The cost of fee timber harvested is based on the volume of timber harvested in relation to the estimated volume of timber recoverable. Logging facilities, which consist primarily
of roads constructed and other land improvements, are depreciated using the straight-line method over a ten-year estimated life. The Companys professional foresters estimate its fee timber inventory using statistical information and data
obtained from physical measurements and other information gathering techniques. The cost of timber and timberland purchased and reforestation costs are capitalized. Fee timber carrying costs are expensed as incurred.
| | -- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The key components of the Timber and Timberlands policy are: (1) managements decision to maintain separate timber cost pools for each legal
entity within the Deltic consolidated group and (2) the required estimation of timber inventory volume, by species, for each of these companies in order to calculate the cost of fee timber harvested per ton. Management has elected to maintain a
separate cost pool for the timber owned by each company, thus resulting in a different cost per ton for fee timber harvested for each. The mix of harvest by company for any period can significantly affect the amount of cost of fee timber harvested
expense reported. Per-ton costs for 2005 ranged from $3.21 to $41.28 per ton for pine sawtimber. Had the Company opted to use a composite depletion rate, cost of pine sawtimber harvested would have been $.8 million more in 2005, $.7 million more in
2004, and $2.3 million more in 2003 ($.5 million, $.5 million, and $1.5 million, respectively, net of applicable income taxes) than as reported due to the mix of harvest by company during the year. In determining these rates, management must
estimate the volume of timber existing on its timberlands. To estimate these fee timber inventories, the Company relies on its experienced forestry personnel and their use of statistical information and data obtained by actual physical measurements
and other information gathering techniques. The cost of fee timber harvested recognized is impacted by the accuracy of this volume estimation. (For additional information about the Companys timber and timberlands, refer to Note 4 to the
consolidated financial statements.)



| | 4) | Property, Plant, and Equipment  Property, plant, and equipment is stated at cost less accumulated depreciation. Depreciation of buildings, equipment, and other
depreciable assets is primarily determined using the straight-line method. Expenditures that substantially improve and/or increase the useful life of facilities or equipment are capitalized. Maintenance and repair costs are expensed as incurred.
Gains and losses on disposals or retirements are included in income as they occur.
| | -- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Property, plant, and equipment assets are
evaluated for possible impairment on a specific asset basis or in groups of similar assets, as applicable, whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to
be held and used is measured by a comparison of the carrying amount of an asset to estimated undiscounted future net cash flows to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment
loss is recognized for the amount by which the carrying amount of the asset exceeds the fair value of the asset. Assets to be disposed of are reported at the lower of the carrying amount or fair value less costs to sell, and depreciation ceases.

Management also evaluates any asset or group of assets for which potential impairment might exist and has determined that there are none
requiring an impairment write-down. This process requires managements estimate of future cash flows generated by each asset or group of assets.

For any instance where this evaluation process might indicate an impairment exists, the appropriate assets carrying values would be written down to
fair value and the amount of the write-down would be charged against the results of continuing operations. (For additional information about the Companys property, plant, and equipment, refer to Note 5 to the consolidated financial
statements.)



| | 5) | Stock-Based Compensation  At December 31, 2005, Deltic had two stock-based compensation plans for which the Company applies the recognition and measurement
principles of APB 25, Accounting for Stock Issued to Employees, and related interpretations in accounting for those plans. Stock-based employee compensation expense is 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. In addition, the Company has awarded
restricted stock awards to selected employees and nonemployee directors. The vesting of these awards are subject to either time restrictions, applying fixed plan accounting standards, or performance restrictions, applying variable plan accounting
standards. (For additional information, see Note 13  Incentive Plans.)

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, for the years

For the pro forma net income calculation in the preceding table, the fair value of each option on
the date of grant was estimated using the Black-Scholes option-pricing model and the following assumptions for awards in 2005, 2004, and 2003, respectively: dividend yields of .81 percent, .9 percent, and 1.01 percent; expected volatility of 31.54
percent, 30 percent, and 32.79 percent; risk-free interest rates of 3.83 percent, 4.1percent, and 4.86 percent; and expected lives of five years. Using these assumptions, the weighted average grant-date fair value per share of options granted in
2005, 2004, and 2003 was $15.35, $9.50, and $7.96, respectively.

##### Table of Contents

The key management decision factors for Stock-Based Compensation are: (1) the decision, to account
for stock-based compensation using the intrinsic value recognition and measurement principles of APB 25, Accounting for Stock Issued to Employees, or the fair value recognition and measurement principles of SFAS 123, Accounting for Stock-Based
Compensation, as amended by SFAS 148, Accounting for Stocked-Based Compensation  Transition and Disclosure, (2) the determination of the exercise price for options granted. As of December 31, 2005, a companys management could
elect to adopt SFAS 123 or continue to use APB 25 for recognizing stock option expense in its financial statements. If continued use of APB 25 was elected, the income statement generally reflected a lesser amount for stock-based compensation
expense, and the potential impact of adopting SFAS 123 and SFAS 148 would only be disclosed on a pro forma basis in the financial statement footnotes. Under the Companys stock incentive plan, option exercise price for options granted was equal
to the fair market per share stock price on the date of the grant, which resulted in no stock-based compensation expense for future options granted under the Companys stock incentive plan. However, options granted in February 2002 were subject
to shareholder approval at the Companys annual stockholders meeting on April 25, 2002, the accounting measurement date for these options. As a result, these options had an intrinsic value of $3.46 per share due to an increase in the
market price of the Companys common stock between February and April, and the resulting stock-based compensation expense is being recognized over the vesting periods of these options. In 2006, the Company will adopt the provisions of SFAS 123
(Revised), Share-Based Payment. This standard requires the Company to expense the fair market value of all stock-based compensation, eliminating the first key management decision factor discussed above, and (3) Performance restricted stock is
subject to specified requirements based on the performance of the Companys stock price, compared to a defined stock index, over the performance period. The ultimate number of shares, subject to performance requirements, awarded will vary
depending on how well the Companys stock performs in relation to this index and could range from zero to 200 percent of the original granted shares. Accordingly, management must evaluate the likelihood of differences between the number of
performance based shares originally granted and the number of shares ultimately awarded. (For additional information about the Companys stock-based compensation, refer to Notes 1 and 13 to the consolidated financial statements.)



| | 6) | Revenue Recognition  The Company recognizes revenue when the following criteria are met: (1) persuasive evidence of an agreement exists, (2) delivery has occurred
or services have been rendered, (3) the price to the buyer is fixed and determinable, and (4) collectibility is reasonably assured. Delivery is not considered to have occurred until the customer takes title and assumes the risks and
rewards of ownership. Revenue from the sale of lumber and wood by-products is recorded at the time of shipment due to terms of such sale being designated free on board (f.o.b.) shipping point. Revenue from the sale of timber-cutting
rights to third parties is recorded when legal title passes to the purchaser, which is generally upon delivery of a legally executed timber deed and receipt of payment for the timber. Revenue from intersegment timber sales is recorded when the
timber is harvested; such intersegment sales, which are made at prices which generally approximate market, are eliminated in the consolidated financial statements. Revenue from timberland and real estate sales is recorded under the criteria of the
Financial Accounting Standards Boards Statement of Financial Accounting Standards (SFAS) 66, Accounting for Sales of Real Estate. Such revenue is recorded at the time the purchaser executes the real estate closing documents and
makes payment to the title company handling the closing.

| | 7) | Income Taxes  The Company uses the asset and liability method of accounting for income taxes. Under this method, the provision for income taxes includes amounts
currently payable and amounts deferred as tax assets and liabilities, based on differences between financial statement carrying amounts and the tax bases of existing assets and liabilities, and is measured using the enacted tax rates that are
assumed will be in effect when the differences reverse. Deferred tax assets are reduced by a valuation allowance which is established when it is more likely than not that some portion or all of the deferred tax assets will not be realized. The
effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.

The key management decisions related to Income Taxes are: (1) the determination of current
taxability of transactions, (2) the election to capitalize or expense costs incurred, (3) the decision regarding the appropriate depreciation method for income tax purposes (these three factors ultimately affect the Companys cash
flows for income taxes paid and determine the differences between the financial statements carrying amounts and tax bases of existing assets and liabilities), and (4) managements estimation of the appropriateness of valuation allowances
to reduce any deferred tax assets that exist. Deltics management periodically evaluates the Companys ability to realize future benefit of deferred tax assets by reviewing the expected turnaround of deferred tax liabilities and the amount
of future taxable income and by evaluating tax planning strategies that could possibly be implemented to realize deferred tax assets.

Related-Party Transactions

The Company has committed to provide to Del-Tin Fiber a portion of the plants fiber and
wood supply at market prices. This arrangement benefits Del-Tin Fiber by ensuring a portion of its raw material needs while providing the Company with a purchaser of residual by-products produced by its lumber mills, if needed. The market price that
Deltic receives for these transactions is determined by the average price paid during the immediate preceding year by Del-Tin Fiber to other suppliers of the products purchased from the Company. During 2005, 2004, and 2003, Deltic sold Del-Tin Fiber
approximately $3.9 million, $3.9 million, and $4.1 million, respectively, of these residual by-products.

Impact of Recent Accounting
Pronouncements

(For information regarding the impact of recent accounting pronouncements, refer to the related section in Note 1 to the
consolidated financial statements.)

Environmental Matters

Deltic is committed to protecting the environment and has certain standards with which it must comply based on federal, state, and local laws for the
protection of the environment. Costs of compliance through 2005 have not been material, and the Companys management currently has no reason to believe that such costs will become material for the foreseeable future.

Contingencies

The Company is
involved in litigation incidental to its business from time to time. Currently, there are no material legal proceedings outstanding other than that disclosed regarding the condemnation of portions of the Companys planned real estate
development, The Ridges at Nowlin Creek.

Outlook

Pine sawtimber harvested from Deltics fee lands in 2006 is projected to remain comparable to 2005s level at 570,000 to 585,000 tons. Finished lumber production and resulting sales volumes are projected at
300 to 315 million feet for 2006; however, these volumes are dependent upon market conditions. With continued growth in west Little Rock, Arkansas, and the existing demand for residential lots in the Companys Chenal Valley development,
Deltic anticipates that closings for residential lots will be 140 to 175 lots for the year of 2006, barring declines in economic growth or residential construction activity. The Company anticipates increased commercial acreage sales activity in 2006
compared to 2005. The Company will continue to recognize equity in the financial results of Del-Tin Fiber.

The Companys capital
expenditures budget for the year of 2006 was prepared in the fall of 2005 and provides for expenditures totaling $44 million. The Woodlands capital budget of $7.9 million includes $5 million for timberland acquisitions, which will be dependent on
the availability of acreage at prices that meet the Companys criteria for timber stocking, growth potential, site index, and location, and $2.2 million for reforestation site preparation and planting. During 2006, various sawmill projects are
expected to require

$9.9 million. The capital budget for Real Estate operations of $25.9 million includes expenditures for residential real estate lot development totaling $10
million, depending on continuation of strong demand for residential lots and other marketing conditions. In addition, $3.5 million is budgeted in 2006 for the construction of additional speculative homes within the Companys Red Oak Ridge
development located in Hot Springs, Arkansas. Also, $5.4 million is budgeted in 2006 for a renovation project at Chenal Country Club. The remainder of budgeted Real Estate segment expenditures are primarily for various infrastructure and other
amenity improvements. Capital and other expenditures are under constant review, and these budgeted amounts may be adjusted to reflect changes in the Companys estimated cash flows from operations, borrowings or repayments under credit
facilities, or general economic conditions.

DELTIC TIMBER CORPORATION

AND SUBSIDIARIES

Notes to Consolidated Financial Statements

December 31, 2005



Note 1  Significant Accounting Policies

Principles of Consolidation  The consolidated financial statements of Deltic Timber Corporation (Deltic or the Company) include the accounts of Deltic and all majority-owned
subsidiaries after elimination of significant intercompany transactions and accounts.

Use of Estimates  In the preparation of the
Companys financial statements in conformity with accounting principles generally accepted in the United States of America, management has made a number of estimates and assumptions related to the reporting of assets and liabilities and the
disclosure of contingent assets and liabilities. Actual results may differ from those estimates.

Cash Equivalents  Cash equivalents include
U.S. government securities that have a maturity of three months or less from the date of purchase.

Allowance for Doubtful Accounts  The
Company provides an allowance for doubtful accounts based on a review of the specific receivables outstanding. At December 31, 2005 and 2004, the balance in the allowance account was $38,000 and $26,000, respectively.

Inventories  Inventories of logs, lumber, and supplies are stated at the lower of cost or market, primarily using the average cost method. Log costs include
harvest and transportation cost as appropriate. Lumber costs include materials, labor, and production overhead. (For additional information, see Note 2  Inventories.)

Investment in Real Estate Held for Development and Sale  Real estate held for development and sale is stated at the lower of cost or net realizable value, and includes direct costs of land and land
development and indirect costs, including amenities. Indirect and amenity costs are allocated to individual lots or acreage sold based on relative sales value. Direct costs are allocated on a specific neighborhood basis, while indirect costs for the
Companys four development areas  Chenal Valley, Chenal Downs, Red Oak Ridge, and the currently suspended The Ridges at Nowlin Creek  are allocated to neighborhoods over the entire respective development area based on relative
retail values.

Investment in Del-Tin Fiber Investment in Del-Tin Fiber L.L.C. (Del-Tin Fiber), a 50 percent-owned limited
liability company, is carried at cost and is adjusted for the Companys proportionate share of Del-Tin Fibers undistributed earnings or losses. The Companys equity-method-basis carrying value for its investment in Del-Tin Fiber is
evaluated for possible impairment, as applicable under the requirements of Accounting Principles Board Opinion (APB) 18, The Equity Method of Accounting for Investments in Common Stock. This evaluation as of December 31, 2002, based
on the intent of the Companys Board of Directors to exit the business, resulted in a determination that the Companys investment was impaired as of December 31, 2002, and the carrying amount of the investment was written off, to
zero, for the 2002 Consolidated Balance Sheet. On December 11, 2003, the Companys Board of Directors revised its intent in regard to selling Deltics interest in the joint venture, and the resulting evaluation of fair value for the
related investment indicated that fair value exceeded carrying value, which was zero as of December 31, 2003, and the Company resumed recording its equity share of the operating results of Del-Tin Fiber. Accordingly, cash advances to the joint
venture subsequent to 2003 were recorded as increases in the Companys investment carrying value, while cash distributions received from the joint venture resulted in reductions in investment carrying value. (For additional information, see
Note 3  Investment in Del-Tin Fiber.)

Note 1  Significant Accounting Policies (cont.)

Timber and Timberlands  Timber and timberlands, which includes purchased stumpage inventory and logging facilities, is stated at acquisition cost less cost
of fee timber harvested and accumulated depreciation of logging facilities and includes no estimated future reforestation cost. The cost of fee timber harvested is based on the volume of timber harvested in relation to the estimated volume of timber
recoverable. Logging facilities, which consist primarily of roads constructed and other land improvements, are depreciated using the straight-line method over a ten-year estimated life. The Company estimates its fee timber inventory using
statistical information and data obtained from physical measurements and other information gathering techniques. The cost of timber and timberland purchased and reforestation costs are capitalized. Fee timber carrying costs are expensed as incurred.

Property, Plant, and Equipment  Property, plant, and equipment is stated at cost less accumulated depreciation. Depreciation of buildings,
equipment, and other depreciable assets is primarily determined using the straight-line method. Expenditures that substantially improve and/or increase the useful life of facilities or equipment are capitalized. Maintenance and repair costs are
expensed as incurred. Gains and losses on disposals or retirements are included in income as they occur.

Property, plant, and equipment
assets are evaluated for possible impairment on a specific asset basis or in groups of similar assets, as applicable, whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of
assets to be held and used is measured by a comparison of the carrying amount of an asset to estimated undiscounted future net cash flows to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an
impairment loss is recognized for the amount by which the carrying amount of the asset exceeds the fair value of the asset. Assets to be disposed of are reported at the lower of the carrying amount or fair value less costs to sell, and depreciation
ceases.

Revenue Recognition  The Company recognizes revenue when the following criteria are met:

(1) persuasive evidence of an agreement exists, (2) delivery has occurred or services have been rendered, (3) the price to the buyer is fixed
and determinable, and (4) collectibility is reasonably assured. Delivery is not considered to have occurred until the customer takes title and assumes the risks and rewards of ownership. Revenue from the sale of lumber and wood by-products is
recorded at the time of shipment due to terms of such sale being designated free on board (f.o.b.) shipping point. Revenue from the sale of timber-cutting rights to third parties is recorded when legal title passes to the purchaser,
which is generally upon delivery of a legally executed timber deed and receipt of payment for the timber. Revenue from intersegment timber sales is recorded when the timber is harvested; such intersegment sales, which are made at prices which
generally approximate market, are eliminated in the consolidated financial statements. Revenue from the leasing of land for hunting purposes is deferred when received and subsequently recognized over the one-year lease term which begins
September 1. At December 31, 2005 and 2004, the Company had deferred hunting lease revenue totaling $1,042,000 and $1,003,000, respectively, reflected in the Consolidated Balance Sheet in Deferred Revenues and Other Accrued Liabilities.
Revenue from bonus payments under mineral leases is deferred and recognized over the lease term, while related royalty payments are recognized when received. Revenue from timberland and real estate is recorded under the criteria of the Financial
Accounting Standards Boards Statement of Financial Accounting Standards (SFAS) 66, Accounting for Sales of Real Estate. Such revenue is recorded when the sale is closed and legal title is transferred, which is generally at the time
the purchaser executes the real estate closing documents and makes payment to the title company handling the closing.

Notes to Consolidated Financial Statements

December 31, 2005



Note 1  Significant Accounting Policies (cont.)

Income Taxes  The Company uses the asset and liability method of accounting for income taxes. Under this method, the provision for income taxes includes
amounts currently payable and amounts deferred as tax assets and liabilities, based on differences between the financial statement carrying amounts and the tax bases of existing assets and liabilities, and is measured using the enacted tax rates
that are assumed will be in effect when the differences reverse. Deferred tax assets are reduced by a valuation allowance which is established when it is more likely than not that some portion or all of the deferred tax assets will not be realized.
The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.

Property Taxes  Property taxes applicable to the Companys assets are estimated and accrued in the period of assessment. At December 31, 2005 and 2004, the Company had accrued property tax expense totaling $1,087,000
and $1,092,000, respectively, reflected in the Consolidated Balance Sheet in Accrued Taxes Other Than Income Taxes.

Stock-Based Compensation 
At December 31, 2005, Deltic had two stock-based compensation plans for which the Company applies the recognition and measurement principles of APB 25, Accounting for Stock Issued to Employees, and related interpretations in accounting for
those plans. Stock-based employee compensation expense is 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. The Company has awarded restricted stock awards to employees, with vesting requirements based on either fulfilling future service periods, which results
in applying fixed-plan accounting standards, or specified performance requirements, which results in applying variable-plan accounting standards. (For additional information, see Note 13  Incentive Plans.)

The effect on net income/(loss) and earnings per share if the Company had applied the fair value recognition provisions of SFAS 123, Accounting for
Stock-Based Compensation, for the years ended December 31 consisted of the following:

Note 1  Significant Accounting Policies (cont.)

For the pro forma net income calculation in the preceding table, the fair value of each option on the date of grant was estimated using the Black-Scholes
option-pricing model and the following assumptions for awards in 2005, 2004, and 2003, respectively: dividend yields of .81 percent, .9 percent, and 1.01 percent; expected volatility of 31.54 percent, 30 percent, and 32.79 percent; risk-free
interest rates of 3.83 percent, 4.1 percent, and 4.86 percent; and expected lives of five years. Using these assumptions, the weighted average grant-date fair value per share of options granted in 2005, 2004, and 2003 was $15.35, $9.50, and $7.96,
respectively.

Pensions and Other Postretirement Benefits  The Company sponsors both a qualified and a nonqualified, noncontributory, defined
benefit retirement plan that covers substantially all employees. Benefits are based on years of service and final career-average-pay formulas as defined by the plans. The qualified plan is funded to accumulate sufficient assets to provide for
accrued benefits. The nonqualified plan, a supplemental executive plan, is not funded; the Company pays any benefits due under this plan on a monthly basis.

The Company also sponsors a defined benefit health care plan and a life insurance benefit plan for substantially all retired employees. The Company measures the costs of its obligations for these plans based on its
best estimate. The net periodic costs are recognized as employees render the services necessary to earn these postretirement benefits. (For additional information, see Note 12  Employee and Retiree Benefit Plans.)

Advertising Costs  Advertising costs, primarily related to marketing efforts for the Companys real estate developments, are expensed as incurred.
These costs amounted to $790,000 in 2005, $692,000 in 2004, and $638,000 in 2003 and are reflected in Cost of Sales on the Consolidated Statements of Income.

Capitalized Interest  The Company capitalizes interest for qualifying assets constructed or otherwise produced for which interest on directly associated debt was incurred. Capitalized interest is added to the cost of the
underlying assets and is amortized over the useful lives of those assets.

Capital Expenditures  Capital expenditures include additions to
Investment in Real Estate Held for Development and Sale; Timber and Timberlands; and Property, Plant, and Equipment.

Net Change in Purchased Stumpage
Inventory  Purchased stumpage inventory consists of timber-cutting rights purchased from third parties specifically for use in the Companys sawmills. Depending on the timing of acquisition and usage of this acquired stumpage
inventory, the net change in this inventory can either be a source or use of funds in the Companys Consolidated Statements of Cash Flows.

Earnings per Common Share  Earnings per share (EPS) amounts presented are calculated under the provisions of the SFAS 128, Earnings per Share. Basic earnings per share is computed based on earnings available to
common shareholders [net income/(loss) less accrued preferred dividends, if any] and the weighted average number of common shares outstanding. The earnings per share assuming dilution amounts presented are computed based on earnings available to
common shareholders and the weighted average number of common shares outstanding, including shares assumed to be issued under the Companys stock incentive plans. (For a reconciliation of amounts used in per share computations, see Note 15
 Earnings per Share.)

Shipping and Handling Costs  Shipping and handling costs, such as freight to our customers destinations,
are accounted for in accordance with the Emerging Issues Task Force (EITF) Issue 00-10. As such, shipping and handling costs are included in Cost of Sales in the Companys Consolidated Statements of Income. These costs, when
included in the amount invoiced to customers, are also recognized in Net Sales.

Note 1  Significant Accounting Policies (cont.)

Impact of Recent Accounting Pronouncements  In January 2004, the FASB issued a FASB Staff Position regarding SFAS 106, Employers Accounting for
Postretirement Benefits Other than Pensions, (FSP FAS 106-1), Accounting and Disclosure Requirements Related to the Medicare Prescription Drug, Improvement and Modernization Act of 2003 (the Act), which allowed companies to
recognize or defer recognizing the effects of the prescription-drug provisions of the new Medicare Act in their 2003 financial statements. Deltic had a September 30, 2003, measurement date for its benefit plans and during the first quarter of
2004 elected to defer recognition of the effects of the Act until the Financial Accounting Standards Board issued final guidance on accounting for the provisions of the Act. Such election did not have a material impact on the Companys
financial statements.

In May 2004, the FASB issued FSP FAS 106-2 which bears the same title as FSP FAS 106-1 and supersedes the previous
guidance therein. FSP FAS 106-2 provides guidance on accounting for postretirement health care plans with prescription drug benefits that have been determined to be at least actuarially equivalent to those provided within the Act and thus qualify
plans for future federal subsidies. Deltic has determined the prescription drug benefits under its plan are actuarially equivalent to those provided within the Act. Accordingly, an adjustment resulting from the Act was included in the postretirement
benefit obligation liability as of December 31, 2004, and the amount of related benefit expense for the period then ended. (For additional information, see Note 12  Employee and Retiree Benefit Plans.)

In November 2004, the FASB released SFAS 151, Inventory Costs, which requires abnormal amounts of idle facility expense, freight, handling costs, and
wasted material (spoilage) to be recognized as current-period charges. It also requires that allocation of fixed production overheads to the costs of conversion be based on the normal capacity of the production facilities. SFAS 151 was effective for
inventory costs incurred during fiscal years beginning after June 15, 2004. Adoption of SFAS 151 did not have a material effect on the Companys consolidated financial statements.

In December 2004, the FASB issued a revision to SFAS 123, Accounting for Stock-Based Compensation. This revision will require the Company to measure the
cost of employee services received in exchange for an award of equity instruments based on the grant-date fair value of the award. The cost will be recognized over the period during which an employee is required to provide service in exchange for
the award. This revised Statement was originally effective as of the beginning of the first interim or annual reporting period that begins after June 15, 2005. It applies to all awards granted after the required effective date and to awards
modified, repurchased, or canceled after that date. In April 2005, the Securities and Exchange Commission announced the adoption of a new rule that amends the compliance dates for SFAS 123 (Revised) and allows for the implementation of SFAS 123
(Revised) at the beginning of the first fiscal year that begins after June 15, 2005. Accordingly, the Company has elected to adopt the revised statement effective for its first quarter 2006 financial statements. As required, cost of stock-based
compensation will be recognized for the portion of outstanding awards for which the requisite service has not been rendered as of December 31, 2005, based on the grant-date fair value of those awards. The granting of stock-based compensation is
at the discretion of the Companys Executive Compensation Committee (the Committee). The effect of adoption of SFAS 123 (Revised) will be dependent upon the amount of awards granted by the Company in future periods, but, on an
annual basis, is expected to be comparable to the amounts reflected in the pro forma disclosures as presented in the Stock-Based Compensation policy included within this footnote.

Note 1  Significant Accounting Policies (cont.)

In December 2004, the FASB issued SFAS 152, Accounting for Real Estate Time-Sharing Transactions, an amendment of FASB Statements No. 66 and 67. This
statement requires real estate time-sharing transactions to be accounted for as nonretail land sales and is effective for fiscal years beginning after June 15, 2005. The Company is not engaged in time-sharing transactions, accordingly, adoption
of SFAS 152 is not expected to have a material impact on the Companys financial statements.

In December 2004, the FASB issued SFAS
153, Exchanges of Nonmonetary Assets, an amendment of APB Opinion No. 29. This statement amends APB 29 concerning the accounting for exchanges of similar productive assets. These transactions will now be accounted for at fair value, the basic
principle for nonmonetary transactions, unless the exchange lacks commercial substance. This statement is effective for nonmonetary asset exchanges occurring in fiscal periods beginning after June 15, 2005. The Company does not expect the
adoption of SFAS 153 to have a material effect on its consolidated financial statements.

In March 2005, the FASB issued Financial
Accounting Standards Board Interpretation (FIN) No. 47, Accounting for Conditional Asset Retirement Obligations. This interpretation clarifies the term conditional asset retirement obligation as used in SFAS 143,
Accounting for Asset Retirement Obligations, and is effective no later than the end of fiscal years ending after December 15, 2005. Adoption of FIN 47 did not have a material effect on the Companys consolidated financial statements.

In May 2005, the FASB issued SFAS 154, Accounting Changes and Error Corrections. This statement requires all changes in accounting
principles to be accounted for by retrospective application to the financial statements for prior periods unless it is impracticable to do so. SFAS 154 carries forward previously issued guidance with respect to accounting for changes in estimates,
changes in the reporting entity and the correction of errors. This statement is effective for accounting changes made in fiscal years beginning after December 15, 2005.

Note 2  Inventories

Inventories at December 31 consisted of the following:

The Company utilizes the lower of cost or market basis for determining inventory carrying values.
Lumber inventory amounts at December 31, 2005 and 2004, are stated at lower of cost or net realizable value.

Note 3  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.

On April 25, 2002, Deltic announced that Banc One Capital Markets, Inc.
had been retained as financial advisor to assist in the evaluation of strategic alternatives for the Companys investment in Del-Tin Fiber. Subsequently, Deltic announced that following a review of these strategic alternatives, it was
determined that the MDF business did not represent a growth area for the Company and that it intended to exit the MDF business upon the earliest, reasonable opportunity provided by the market. As a result of this decision, the Companys
evaluation of possible impairment of the carrying value of its investment in the equity method investee, as required by APB 18, was based primarily upon the estimated cash flows from a sale of the Companys interest during 2003 and resulted in
a determination that the Companys investment was impaired as of December 31, 2002, and the carrying amount of such investment was written off, to zero, for the Companys 2002 Consolidated Balance Sheet.

Due to the Companys commitment to fund its share of the facilitys operating working capital needs until the facility was able to consistently
generate sufficient funds to meet its cash requirements or Deltics ownership was sold, the Company continued to recognize its share of Del-Tin Fibers operating losses to the extent of these advances during 2003. For the year,
Deltics operating advances to the facility approximated its equity share of losses of the plant and amounted to $4,729,000. Deltic made additional advances of $4,228,000, during 2003, representing its half of the facilitys 2003 quarterly
sinking fund obligation, which the Company had recorded as a current contingent liability in 2002, in accordance with SFAS 5, Accounting for Contingencies. The Company also continued to utilize its management resources to work with Del-Tins
management and the joint venture partner to improve operating performance at the plant. As a result of these improvements, on December 11, 2003, Deltics Board of Directors revised its intent regarding the Companys investment in
Del-Tin Fiber and ceased efforts to sell the Companys interest in the joint venture while continuing to improve operating and financial results of the plant. Due to this decision, Deltics evaluation of impairment as of December 31,
2003, was primarily based upon the estimated future net cash flows from Del-Tin Fibers operations over the remaining life of the plant. Considering the Companys revised intent, the resulting estimated fair value of the Companys
investment exceeded the investments carrying value, which was zero as of December 31, 2003, and the Company resumed recording its equity share of the operating results of Del-Tin Fiber and recording cash advances as increases in its
investment in the facility, while cash distributions received from the joint venture decrease its investment.

In performing the respective
impairment evaluations, the Companys management made a number of estimates and assumptions related to future operating results for Del-Tin Fiber, the sale of its ownership interest, the expected selling price for its investment if sold, and
the ability to refinance the joint ventures long-term debt. The management of Del-Tin Fiber has performed evaluations of possible impairment of the long-lived assets of the plant in accordance with SFAS 121 and/or SFAS 144, as applicable.
To-date, these analyses have indicated that no impairment exists at the Del-Tin Fiber level.

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 3  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 pursuant to which, $60,000,000 of its $89,000,000 industrial revenue bonds were redeemed. Under the new credit agreement, the lenders, on September 1, 2004, loaned Del-Tin Fiber $30,000,000 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 $29,689,000 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 ($26,095,000 at December 31, 2005) 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 December 31, 2005, Deltics remaining liability regarding the guarantee was $2,588,000.

Under the operating agreement, Del-Tin Fibers employees operate the plant. Deltic has committed to provide a portion of the plants fiber and
wood fuel supply at market prices. During 2005, 2004, and 2003, Deltic sold Del-Tin Fiber approximately $3,868,000, $3,890,000, and $4,099,000, respectively, of these lumber manufacturing by-products. As of December 31, 2005 and 2004, the
Company had a receivable from Del-Tin Fiber of $81,000 and $54,000, respectively.

Del-Tin Fibers financial position at year-end 2005
and 2004 and results of operations for years of 2005 and 2004 consisted of the following:

At December 31, 2005 and 2004, the Companys share of the underlying net assets of
Del-Tin Fiber exceeded its investment by $16,193,000 and $15,502,000, respectively. The excess relates primarily to the Companys write-off of its carrying amount for its investment in Del-Tin Fiber as of December 31, 2002, and the
estimated fair value of the guarantee of Del-Tin Fibers credit agreement recorded by the Company in its Consolidated Balance Sheet.

Prior to the 2002 write-off of its investment in Del-Tin Fiber, the Company accounted for its investment in Del-Tin Fiber under the equity method. During 2003, the Company expensed amounts related to the funding of operating deficits.
Effective December 11, 2003, as a result of the Companys intent to not sell its investment in Del-Tin Fiber, Deltic resumed accounting for the investment using the equity method.

Accordingly, the investment in Del-Tin Fiber is carried at cost, adjusted for the Companys proportionate share of undistributed earnings or losses.
Cumulative net losses for the facility have amounted to $95,067,000, $47,534,000 net to the Company. During 2005 and 2004, the Company received $3,800,000 and $1,400,000 in distributions from Del-Tin Fiber, respectively. Prior to 2004, no earnings
have been available for distribution to the owners. Contributions to Del-Tin Fiber by the Company as of December 31, 2005, have amounted to $73,378,000.

Note 6  Credit Facilities

On September 9, 2005, the Company entered into an agreement with Sun Trust Bank and other banks which provides an unsecured, committed revolving credit facility totaling $260,000,000, which includes a $50,000,000
letter of credit feature. The agreement will expire September 9, 2010 and replaced the Companys former facility, which totaled $125,000,000, that was scheduled to expire July 15, 2007. As of December 31, 2005 and 2004,
$253,354,000 and $109,300,000, respectively, was available in excess of all borrowings outstanding under or supported by the respective facilities. Borrowings under the current agreement bear interest at a base rate or an adjusted Eurodollar rate
plus an applicable margin, depending upon the type of loan the Company executes. The applicable margin component of the interest rate varies with the type of loan and the Companys total debt to capital ratio. Borrowings outstanding at
December 31, 2005 and 2004, amounted to $4,500,000 and $15,700,000, respectively. In addition, the Company had an outstanding letter of credit under the facility in the amount of $2,146,000 at December 31, 2005. No letters of credit
supported by the facility were present at December 31, 2004. Fees associated with the current revolving credit facility include a commitment fee of .15 to .375 percent per annum on the unused portion of the committed amount. The agreement
contains restrictive covenants, including limitations on the incurrence of debt, a minimum consolidated net worth of the sum of $165,000,000, plus 50 percent of cumulative consolidated net income from April 1, 2005, and a maximum leverage ratio
of .6 to 1. The Company incurred aggregate costs of $890,000 related to the securing of the current facility, which was deferred and is being amortized as additional interest expense over the term of the agreement.

The Company may also borrow up to $1,000,000 under a short-term credit facility with BancorpSouth. The agreement expires December 15, 2006, with
renewal annually. The amount available to the Company under this facility is reduced by any borrowings by Deltic. As of December 31, 2005 and 2004, Deltic had no borrowings outstanding under this line of credit, resulting in $1,000,000
available to the Company. Borrowings bear interest based upon the New York Prime. Deltic also has an agreement with BancorpSouth which provides a $2,000,000 letter of credit facility. This agreement expires December 15, 2006, with renewal
annually. Amounts available to the Company under the facility are reduced by any letters of credit issued on behalf of the Company. Outstanding letters of credit as of December 31, 2005 and 2004, were $543,000 and $706,000, respectively,
resulting in $1,457,000 and $1,294,000, respectively, available to Deltic.

In addition, Deltic has an agreement with Regions Bank which
provides a $1,000,000 letter of credit facility. The agreement expires in 2010. Amounts available to Deltic under the facility are reduced by any letters of credit issued on behalf of the Company. Outstanding letters of credit as of
December 31, 2005 and 2004, were $22,000 and $480,000, respectively, leaving $978,000 and $520,000, respectively, available to the Company. (For additional information regarding these financial instruments, see Note 10  Fair Value of

The $4,500,000 of notes payable designated as due in 2010 represents the outstanding balance under the Companys revolving credit facility agreement with SunTrust Bank and a group of other banks. The agreement will expire on
September 9, 2010. The Company incurred aggregate costs of $890,000 related to the securing of this facility, which was deferred and is being amortized as additional interest expense over the term of the agreement.

During 1998, the Company successfully completed negotiation of the private placement of $40,000,000 of senior notes with Pacific Coast Farm Credit, a
division of American AgCredit. These unsecured notes have a fixed stated interest rate of 6.7 percent and mature on December 18, 2008. No installment payments are required, but the terms allow for prepayments at the option of the Company. The
agreement contains certain restrictive financial covenants, including a minimum consolidated tangible net worth of the sum of $135,000,000, plus 25 percent of cumulative consolidated adjusted net income from October 1, 1998, and a maximum
funded debt/capitalization ratio of .6 to 1. The Company incurred $226,000 of costs related to the issuance of these notes, which was deferred and is being amortized as additional interest expense over the term of the underlying debt. In
anticipation of issuance of these notes, the Company entered into and settled an interest rate hedge contract. Upon settlement of this contract in December 1998, the Company paid $1,081,000, which was deferred and is being amortized as other debt
expense over the term of the underlying debt, resulting in an effective interest rate for these notes of approximately 6.9 percent.

On
December 20, 2002, Deltic successfully completed the private placement of $30,000,000 of senior notes with Metropolitan Life and a group of other domestic insurance companies. These unsecured notes have a fixed stated interest rate of 6.01
percent and mature on December 20, 2012. Semiannual installments of $3,333,000, or such lesser amount as shall be outstanding, are required beginning on December 20, 2008. The note terms allow for prepayment at the option of the Company in
an amount of not less than five percent of the principal amount outstanding at the time of any prepayment. The agreement contains certain restrictive financial covenants, including a minimum consolidated tangible net worth of the sum of
$148,299,000, plus 25 percent of cumulative consolidated adjusted net income from July 1, 2002, and a maximum consolidated debt to consolidated net capitalization ratio of .6 to 1. The Company incurred $179,000 of costs related to the issuance
of these notes, which was deferred and is being amortized as additional interest expense over the term of the underlying debt.

The
scheduled maturities of long-term debt for the next five years are $24,000 in 2006, zero in 2007, $43,333,000 in 2008, $6,667,000 in 2009, and $11,167,000 in 2010. (For additional information regarding financial instruments, see Note 6  Credit

An analysis of the Companys deferred tax assets and deferred tax liabilities at December 31, 2005 and 2004, showing the tax effects of
significant temporary differences, consisted of the following:

Net long-term deferred tax liabilities were $9,995,000 at December 31, 2005, and $14,272,000
at December 31, 2004. In addition, short-term deferred tax assets of $995,000 at December 31, 2005, and $736,000 at December 31, 2004, are included in the Consolidated Balance Sheets in Prepaid Expenses and Other Current Assets for
the respective years.

In assessing the realizability of deferred tax assets, Deltics management considers whether it is more likely
than not that some portion or all of the Companys total deferred tax assets will not be realized. The ultimate realization of these deferred tax assets is dependent upon the generation of future taxable income during the periods in which those
temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income, and tax planning strategies in making this assessment. Based on the level of historical taxable income
and projections for future taxable income over the periods in which the temporary differences are anticipated to reverse, management believes it is more likely than not that the Company will realize the benefits of its deferred tax assets at
December 31, 2005, as reductions of future taxable income or by utilizing available tax planning strategies. However, the amount of the net deferred tax assets considered realizable could be adjusted in the future if estimates of taxable income
are revised.

As of December 31, 2005 and 2004, the Company had valuation allowances of zero and $2,612,000, respectively, to reduce
its deferred tax assets to estimated realizable value. The valuation allowances relate to the deferred tax assets arising from state tax loss carryforwards. The net changes in the valuation allowances were decreases of $2,612,000 and $299,000 in
2005 and 2004, respectively, and an increase of $769,000 in 2003, and were principally due to changes in potential use or expiration of net operating losses for state tax purposes. In 2005, the Company reduced its valuation allowance to zero based
on current projections of increased future taxable income, as it is now more likely than not that the future benefits of these state net operating losses will be utilized in their entirety.

Note 8  Income Taxes (cont.)

At December 31, 2005, the Company had operating loss carryforwards for state tax purposes of approximately $31,546,000. Of this amount, $22,527,000
expires in 2007 and $9,019,000 expires in 2008. At December 31, 2005 and 2004, the Company had prepaid federal income taxes totaling $1,435,000 and $342,000, respectively, reflected in the Consolidated Balance Sheet in Prepaid Expenses and
Other Current Assets. In addition, the Company had expected net federal tax refunds of $367,000 and $637,000 at December 31, 2005 and 2004, respectively, reflected in the Consolidated Balance Sheets in Other Receivables.

The Company was part of the consolidated income tax return of its former parent, Murphy Oil Corporation (Murphy Oil), for periods prior to its
spin-off on January 1, 1997. Under the terms of a tax sharing agreement between the Company and Murphy Oil which governs tax matters for this period, Murphy Oil personnel handle the administration of any tax disputes. During 2003, Murphy Oil
closed the audit of its returns for 1992 1994, and Deltic paid Murphy Oil $325,000 in additional taxes which resulted in additional deferred tax assets related to its investment in real estate held for development and sale. Therefore, such
settlement had no material impact on total income tax expense/(benefit). With this settlement, all tax years under the tax sharing agreement are now closed, and the Company anticipates no further adjustments relating to returns filed during those
years.

Note 9  Stockholders Rights Plan

The Company has a Stockholders Rights Plan, which provides for each eligible common shareholder to receive a dividend of one preferred stock purchase right (Right) for each outstanding share of the Companys common stock
held. The Rights will expire on December 31, 2006, unless earlier exchanged or redeemed. The Rights will detach from the common stock and become exercisable: (1) following a specified period of time after the date of the first public
announcement that a person or group of affiliated or associated persons (Acquiring Person), other than certain persons, has become the beneficial owner of 15 percent or more of the Companys common stock or (2) following a
specified amount of time of the commencement of a tender or exchange offer by any Acquiring Person, other than certain persons, which would, if consummated, result in such persons becoming the beneficial owner of 15 percent or more of the
Companys common stock. In either case, the detachment of the Rights from the common stock is subject to extension by a majority of the directors of the Company. The Rights have certain antitakeover effects and will cause substantial dilution
to any Acquiring Person that attempts to acquire the Company without conditioning the offer on a substantial number of Rights being acquired. The Rights are not intended to prevent a takeover, but rather are designed to enhance the ability of the
Board of Directors of the Company to negotiate with an acquiror on behalf of all the shareholders. Other terms of the Rights are set forth in, and the foregoing description is qualified in its entirety by, the Rights Agreement between the Company
and Harris Trust and Savings Bank, as Rights Agent.

Note 11  Concentration of Credit Risks

Financial instruments which potentially subject the Company to credit risk are trade accounts receivable. These receivables normally arise from the sale
of wood products and real estate. Concentration of credit with respect to these trade accounts receivable is limited due to the large number of customers comprising the Companys customer base. No single recurring customer accounted for a
significant amount of the Companys sales of wood products or real estate in 2005, 2004, or 2003. At December 31, 2005, one lumber sales customers receivable accounted for approximately 12 percent of the Companys consolidated
trade accounts receivable amount. At December 31, 2004, there were no significant accounts receivable from a single customer.

Note 12  Employee and Retiree Benefit Plans

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. The Company uses a September 30 measurement date for its plans.

Note 12  Employee and Retiree Benefit Plans (cont.)

The discount rate assumption used by the Company to measure benefit obligations and net periodic expenses is based on the estimated interest rate at which
the benefit obligations of its plans can be settled. In determining the discount rate as of the measurement date of its plans, the Company considers corporate bonds with ratings of Aaa or Aa, which are deemed high quality, as well as the general
level of interest rates since the last measurement date.

To develop the expected long-term rate of return on asset assumption, the Company
considered the current level of expected returns on risk-free investments (primarily government bonds), the historical level of the risk premium associated with the other asset classes in which the portfolio is invested, and the expectations for
future returns of each asset class. The expected return for each asset class was then weighted, based on the target asset association, to develop the expected long-term rate of return on asset assumption for the portfolio. The returns were adjusted
to account for plan expenses. This resulted in the selection of the 7.50% assumption.

Retirement Plans  The accumulated benefit obligations
(ABO) for the Companys retirement plans were $18,882,000 and $16,345,000 at December 31, 2005 and 2004, respectively. For the Companys qualified plan, the projected benefit obligation (PBO) exceeded the fair
value of plan assets by $6,571,000 and $4,756,000 at December 31, 2005 and 2004, respectively. The qualified plans ABO at December 31, 2005, exceeded the fair value of plan assets by $2,085,000 and accordingly, a liability is
included in the 2005 Consolidated Balance Sheet in Other Noncurrent Liabilities. A corresponding amount is required to be recognized as an intangible asset to the extent of the unrecognized prior service cost for the qualified plan. Any excess of
the minimum pension liability adjustment above the intangible asset is recorded as a separate component and reduction of stockholders equity. Accordingly, at December 31, 2005, an intangible asset of $357,000 is included in the 2005
Consolidated Balance Sheet in Deferred Charges and Other Assets. In addition, $618,000, net of the related income tax benefit of $216,000, is included in the 2005 Consolidated Balance Sheet in Accumulated Other Comprehensive Income. The qualified
plans ABO at December 31, 2004 exceeded the fair value of plan assets by $718,000 and accordingly, a liability is included in the 2004 Consolidated Balance Sheet in Other Noncurrent Liabilities. The Company does not fund its nonqualified
plan; therefore, this plan has no assets. At year-end 2005 and 2004, the PBO for this nonqualified plan was $2,726,000 and $2,808,000, respectively. The Company recorded an actuarial determined liability, related to this nonqualified plan, in the
amount of $2,413,000 at December 31, 2005, and $2,490,000 at December 31, 2004, which is reflected in the Consolidated Balance Sheets in Other Noncurrent Liabilities. As of December 31, 2004, the ABO for the nonqualified plan exceeded
the actuarial liability by $18,000. As a result, the Company recorded the appropriate additional minimum pension liability for this amount, which is reflected in the 2004 Consolidated Balance Sheet in Other Noncurrent Liabilities. Since the Company
had no previously unrecognized prior service cost to offset this additional liability, these amounts were recorded as a component of stockholders equity, net of the related income tax benefit of $6,000, in the 2004 Consolidated Balance Sheet
in Accumulated Other Comprehensive Income.

The weighted average asset allocation for the Companys qualified retirement plan at
December 31, 2005 and 2004, by asset category, consisted of the following:

Note 12  Employee and Retiree Benefit Plans (cont.)

Equity securities generally consist of common stocks. Investment in debt securities are limited to U.S. government securities, high quality corporate
bonds, and mortgage-backed securities. Cash equivalents are limited to U.S. government obligations.

The primary investment goals are:
(1) preservation of principle, (2) investment in a balanced portfolio, and (3) growth of assets to exceed inflation. To meet these goals, the Companys Investment Committee has adopted the above target asset allocation ranges as
outlined in the investment policy for the qualified retirement plan. These ranges allow for flexibility to meet investment goals without exposing the plans assets to excessive risk.

The current funding status of the qualified retirement plan is expected to require the Company to make a contribution during 2006 of $700,000. Deltic
expects to contribute $225,000 in 2006 to fund benefits to be paid from its nonqualified retirement plan. Estimated benefits to be paid from the retirement plans amount to $777,000 in 2006, $847,000 in 2007, $871,000 in 2008, $917,000 in 2009,
$988,000 in 2010, and $6,572,000 in the period 2011 through 2015.

Other Postretirement Benefits  The Company sponsors a plan
that provides comprehensive health care benefits (supplementing Medicare benefits for those eligible) and life insurance benefits for retired employees. Costs are accrued for this plan during the service lives of covered employees. Retirees
contribute a portion of the self-funded cost of health care benefits; the Company contributes the remainder. The Company pays premiums for life insurance coverage, arranged through an insurance company. The health care plan is funded on a
pay-as-you-go basis. The Company retains the right to modify or terminate the benefits and/or cost sharing provisions.

During the third
quarter of 2004, Deltic applied the effect of the Medicare Prescription Drug, Improvement and Modernization Act of 2003 to its obligation under the Companys other postretirement benefits plan. The prescription drug benefits offered by the
Companys plan were determined to be at least actuarially equivalent to those provided with the Act, which qualifies the plan to receive federal subsidy payments under Medicare Part D. The amount of the reduction in the Companys
obligation under the plan relating to benefits received from the Act attributable to past service was $590,000. The reduction in the postretirement benefit expense for 2004, as a result of the application of the federal subsidy, was $65,000.
Estimated contributions by the Company for other postretirement benefits, net of the expected Medicare Part D subsidy, amount to $362,000 in 2006, $383,000 in 2007, $446,000 in 2008, $492,000 in 2009, $558,000 in 2010, and $3,515,000 in the period
2011 through 2015.

In determining the benefit obligation for health care at December 31, 2005, health care inflation cost was assumed
to increase at an annual rate of ten percent in 2005, then decreasing one percent per year to five percent in 2010 and thereafter. Assumed health care cost trend rates have a significant effect on the amounts reported for the health care plan. A one
percentage-point increase in the assumed health care cost trend would increase the aggregate service and interest cost components of periodic benefit cost for 2005 by $95,000 and the benefit obligation by $734,000, while a one percentage-point
decrease in the assumed rate would decrease the 2005 cost components by $84,000 and the benefit obligation by $639,000.

Thrift Plan 
Employees of the Company may participate in its thrift plan by allotting up to a specific percentage of their base pay. The Company matches contributions at a stated percentage of each employees allotment. Company contributions to this plan
were $625,000 in 2005, $342,000 in 2004, and $311,000 in 2003.

Note 13  Incentive Plans

Stock Incentive Plan

On April 25, 2002, the Companys shareholders approved the Deltic
Timber Corporation 2002 Stock Incentive Plan (the 2002 Plan). The 2002 Plan replaced the 1996 Stock Incentive Plan (the 1996 Plan), which was terminated. At December 31, 2005, remaining outstanding options under the 1996
Plan totaled 59,409 shares, all of which were exercisable. No further awards will be made under the 1996 Plan. Outstanding options under the 1996 Plan will expire from 2006 to 2011 if not exercised and have an average exercise price of $25.54 based
on the fair market value at date of grant.

The 2002 Plan permits annual awards of shares of the Companys common stock to executives,
other key employees, and nonemployee directors. Under the plan, the Executive Compensation Committee (the Committee) is authorized to grant: (1) stock options; (2) restricted stock and restricted stock units;
(3) performance units; and (4) other stock-based awards, including stock appreciation rights and rights to dividends and dividend equivalents. The number of shares available for issuance under the 2002 Plan is 1,800,000 shares unless
adjustment is determined necessary by the Committee as the result of dividend or other distribution, recapitalization, stock split, reverse stock split, reorganization, merger, consolidation, split-up, spin-off, combination, repurchase or exchange
of common stock, or other corporate transaction in order to prevent dilution or enlargement of benefits or potential benefits intended to be made available. At December 31, 2005, 1,391,296 of these 1,800,000 shares were available for award
under the 2002 Plan. No participant in the 2002 Plan may receive options and stock appreciation rights in any calendar year that relates to more than 50,000 shares, and the maximum number of shares which may be awarded as restricted stock and
restricted stock units or other stock-based awards is 180,000 shares. The Company applies the intrinsic value method of APB 25 to account for stock-based compensation, accruing costs of any stock options and restricted stock over the respective
vesting/performance periods. The cost of stock-based compensation is reflected in General and Administrative Expenses on the Consolidated Statements of Income and amounted to $1,179,000 in 2005, $720,000 in 2004, and $339,000 in 2003. (For
additional information regarding the Companys stock-based compensation, including the effect on net income/(loss) and earnings per share if the Company had applied the fair value recognition provisions of SFAS 123, see Note 1 
Significant Accounting Policies.)

Stock Options  For each option granted under the 2002 Plan, the Committee fixes the option price at not
less than fair market value on the date of the grant and the option term, not to exceed 10 years from date of grant. (Options granted in 2002 were awarded in February 2002 subject to shareholder approval in April. As a result of an increase in the
market value of the Companys common stock from the grant date to the approval date, these options have an intrinsic value of $3.46 per share. The resulting fixed stocked-based compensation cost was recognized over the vesting period for these
options.) Replacement options granted due to the spin-off from Murphy Oil were for ten years from original grant date and nonqualified. New options granted in 1997 and 1998 were for ten years and primarily incentive. Options granted since 1998 have
been for ten years and nonqualified. All outstanding options have an option price not less than the market value on the grant date, with a range in option prices of $22.0625 to $44.355 per share. For options granted in 1997, exclusive of replacement
options, one-half could be exercised or surrendered after two years and the remainder after three years. For options granted from 1998 through 2001, one-half could be exercised or surrendered after one year and the remainder after three years.
During 2003, the Company granted options for 129,750 shares. For 121,750 shares granted in 2003, one-half may be exercised or surrendered after one year and the remainder after three years, and the remaining 8,000 shares awarded to nonemployee
directors at an option price of $24.31 in 2003, were vested immediately when awarded. During 2004, the Company granted options for 39,687 shares, at an option price of $32.565, one-fourth may be exercised or surrendered after each one-year period
over the subsequent four years from issuance. The Company granted options for 36,160 shares in 2005 at an option price of $44.355, one-fourth may be exercised or surrendered after each one-year period over the subsequent four years from issuance.

The fair value per share of restricted stock granted in 2005 and 2004, at the date of grant, was
$44.07 and $32.54, respectively. Unearned compensation was charged for the market value of the granted restricted shares. Unearned compensation is shown as a reduction of stockholders equity in the Consolidated Balance Sheets as Unamortized
Restricted Stock Awards. The shares granted in 2005 and 2004 contain vesting requirements based on fulfilling future service periods, with the unearned compensation is being amortized to expense over the four-year restricted period.

Performance Units  Performance units granted under the 2002 Plan may be denominated in cash, common shares, other securities, other awards allowed under the
2002 Plan, or other property and shall confer on the holder thereof rights valued as determined by the Committee and payable to, or exercisable by, the holder, in whole or in part, upon achievement of such performance goals during such performance
periods as the Committee shall establish. Subject to the terms of the 2002 Plan, the performance goals to be achieved during any performance period, the length of any performance period, the amount of any performance unit granted, and any payment or
transfer to be made pursuant to any performance unit shall be determined by the Committee. During 2005 and 2004, the Company issued performance units in the form of restricted stock with specified performance requirements. During the vesting period,
the grantee may vote and receive dividends on the shares, but shares are subject to transfer restrictions and are all, or partially, forfeited if a grantee terminates, depending on the reason.

Changes in shares of restricted stock performance units outstanding consisted of the following:

The fair value per share of restricted stock performance units granted in 2005 and 2004, at the
date of grant, was $44.07 and $32.54, respectively. Unearned compensation was charged for the market value of the granted restricted shares. Unearned compensation is shown as a reduction of stockholders equity in the Consolidated Balance
Sheets as Unamortized Restricted Stock Awards. The shares granted in 2005 and 2004 contain specified performance requirements, and accordingly market value of the granted restricted shares is adjusted to reflect the current market value of the
Companys stock, as required by variable-plan accounting standards, and the adjusted total unearned compensation is being amortized to expense over the four-year performance period. The specified performance requirements related to these awards
are based on the performance of the Companys stock price, compared to a defined stock index, over the performance

period. The ultimate number of shares, subject to performance requirements, awarded under the plan will vary depending on how well the Companys
stock performs in relation to this index and could range from zero to 200 percent of the original granted shares. The Company evaluates the likelihood of differences between the number of performance based shares originally granted and the number of
shares ultimately awarded and at December 31, 2005 and 2004, the awards remained at 100 percent of the original grants, less shares forfeited.

Other Stock-based Awards  The Committee may also grant other awards, including but not limited to, stock appreciation rights and rights to dividends and dividend equivalents that are denominated, or payable in, valued in whole
or in part by reference to, or otherwise based on or related to shares of the Companys common stock, including securities convertible in its common stock, as deemed by the Committee to be consistent with the purpose of the 2002 Plan. No such
other stock-based awards have been granted.

Incentive Compensation Plan

Cash Awards  The Company has an incentive compensation plan that provides for annual cash awards to officers and key employees based on actual results for a
year compared to objectives established by the Executive Compensation Committee, which administers the Plan, at the beginning of that year. Provisions for cash incentive awards of $1,571,000, $1,205,000, and $703,000 were recorded in 2005, 2004, and
2003, respectively. At December 31, 2005 and 2004, the Company had accrued provisions for cash incentive awards totaling $1,541,000 and $1,275,000, respectively, reflected in the Consolidated Balance Sheet in Deferred Revenues and Other Accrued
Liabilities.

Note 14  Supplemental Cash Flows Disclosures

Income taxes paid, net of refunds, were $10,654,000, $5,382,000 and 2,538,000 in 2005, 2004, and 2003, respectively. Interest paid was $5,478,000, $5,746,000 and $6,425,000 in 2005, 2004, and 2003, respectively. No
interest was capitalized in 2005, 2004, or 2003.

Noncash investing and financing activity excluded from the Consolidated Statement of Cash
Flows for 2005 was the noncash issuance of restricted stock awards in the amount of $1,683,000. Noncash investing and financing activities excluded from the Consolidated Statement of Cash Flow for 2004 were a noncash accrual recorded in 2004 for the
Companys estimated fair value of its guarantee of Del-Tin Fibers long-term debt in the amount of $3,450,000, noncash purchases of treasury stock in the amount of $254,000, and the noncash issuance of restricted stock awards in the amount
of $1,249,000.

DELTIC TIMBER CORPORATION

AND SUBSIDIARIES

Notes to Consolidated Financial Statements

December 31, 2005



Note 16  Commitments and Contingencies

Commitments  Commitments for capital expenditures at December 31, 2005, were approximately $298,000 for timber and timberlands; $1,545,000 for property, plant, and equipment; and $13,143,000 for
investment in real estate held for development and sale.

Contingencies  The Company has various contingencies related to its investment in
Del-Tin Fiber and has either recorded such contingencies into its financial statements or disclosed the conditions of the contingency as required by SFAS 5, Accounting for Contingencies, and FIN 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. (For the details of these contingencies, see Note
3  Investment in Del-Tin Fiber.)

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. Under Arkansas law, Deltic has the right, and has initiated proceedings to have a jury determine
the true amount of just compensation for the lands, as well as other damages. The court hearing regarding this matter is scheduled to begin 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 until 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 liability equal to these cash proceeds received has been included in the Companys Consolidated Balance Sheet at December 31, 2005.

The Company is also involved in other litigation incidental to its business from time to time. Currently, there are no material other legal proceedings
outstanding.

Note 17  Business Segments

The Companys four reporting segments consist of Deltics three operating business units and its corporate function. Each reporting entity has a separate management team and infrastructure that offers
different products and/or services.

Woodlands operations manage the Companys Southern Pine timberlands located primarily in Arkansas
and north Louisiana and derive revenue from the harvest of timber from the timberlands in accordance with its harvest plans, and either sells timber to third parties in the domestic market or to the Companys Mills segment for conversion into
lumber. In addition, this segment may, from time to time, identify and sell a portion of its timberland holdings that is either non-strategic to future timberland management activities or has appreciated, due primarily to location, to a level that
exceeds its value as a timber-growing asset. This segment also generates revenue from the leasing of hunting, oil and gas, and other rights on its timberlands.

The Mills segment consists of Deltics two sawmills which convert timber, purchased from third parties or the Companys Woodlands segment, into lumber. These mills produce a variety of products, including
dimension lumber, boards, timbers, decking, and secondary manufacturing products, such as finger-jointed studs. These products are sold primarily to wholesale distributors, lumber treaters, and truss manufacturers in the South and Midwest and used
in residential construction, roof trusses and laminated beams.

Real Estate operations, which include real estate developments, add value to
former timberland by developing it into upscale, planned residential and commercial developments. These developments, which are generally centered around a core amenity, are being developed in stages. To-date, real estate sales have consisted
primarily of residential lots sold to builders or individuals, commercial site sales, and sales of undeveloped acreage. In addition, this segment currently leases retail and office space to third parties in a retail center constructed by the
Company, and held for sale, in one of its developments. This segment also manages: (1) a real estate brokerage subsidiary which currently generates commission revenue by reselling existing homes and (2) a country club operation, Chenal
Country Club, Inc., around which the Companys Chenal Valley development is centered. This club operation derives its revenues from membership services, food and beverage sales, and membership dues.

Corporate operations consist primarily of senior management, accounting, information systems, human resources, purchasing, treasury, income tax, and legal
staff functions that provide support services to the operating business units. The Company currently does not allocate the cost of maintaining these support functions to its operating units.

The accounting policies of the reportable segments are the same as those described in Note 1  Significant Accounting Policies. The Company evaluates
the performance of its segments based on operating income before results of Del-Tin Fiber, an equity method investee; interest income and expense; other nonoperating income or expense; and income taxes. Intersegment revenues consist primarily of
timber sales from the Woodlands segment to the Mills operations.

The management of Deltic Timber Corporation has prepared and is responsible for the Companys consolidated financial statements. The statements are prepared in
conformity with accounting principles generally accepted in the United States of America, appropriate in the circumstances. In preparing the financial statements, management has, when necessary, made judgments and estimates with consideration given
to materiality.

The Companys consolidated financial statements have been audited by KPMG LLP, an independent registered public accounting firm, who

Accounting Oversight Board (United States). The Audit Committee of the Board of Directors (the Audit Committee) appoints the independent auditors; ratification of the appointment is solicited annually from the shareholders.

The Audit Committee is composed of directors who are not officers or employees of the Company and who have been determined by the Companys Board of Directors to
meet applicable independence standards under the Securities Exchange Act of 1934. The Audit Committee meets periodically with KPMG LLP, the Companys internal auditor, and representatives of management to review the Companys internal
controls, the quality of its financial reporting, the scope and results of audits, and the independence of the external auditors. The Companys internal auditor and KPMG LLP have unrestricted access to the Audit Committee, without
managements presence, to discuss audit findings and other financial matters.

MANAGEMENTS REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

The Shareholders

Deltic Timber Corporation:

The management of Deltic Timber Corporation is responsible for establishing and maintaining adequate internal control
over financial reporting, and for performing an assessment of the effectiveness of internal control over financial reporting as of December 31, 2005. Internal control over financial reporting is a process designed to provide reasonable
assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. The Companys system of internal control over financial
reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company; (2) provide reasonable
assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and the receipts and expenditures of the Company are being made only in accordance with
authorizations of management and directors of the Company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the Companys assets that could have a material
effect on the financial statements.

Deltics management performed an assessment of the effectiveness of the Companys internal control over
financial reporting as of December 31, 2005, based upon criteria in Internal Control  Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on its assessment,
management determined that the Companys internal control over financial reporting was effective as of December 31, 2005, based on the criteria in Internal Control  Integrated Framework issued by COSO.

LLP, an independent registered public accounting firm, as stated in their report which appears herein.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors

Deltic Timber Corporation:

We have audited the accompanying consolidated balance sheets of Deltic Timber Corporation and
Subsidiaries as of December 31, 2005 and 2004, and the related consolidated statements of income, comprehensive income, stockholders equity, and cash flows for each of the years in the three-year period ended December 31, 2005. These
consolidated financial statements are the responsibility of the Companys management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits.

We conducted our audits 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. An
audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Deltic Timber
Corporation and Subsidiaries as of December 31, 2005 and 2004, and the results of their operations and their cash flows for each of the years in the three-year period ended December 31, 2005, in conformity with U.S. generally accepted

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors

Deltic Timber Corporation:

We have audited managements assessment, included in the accompanying Managements
Report on Internal Control over Financial Reporting , that Deltic Timber Corporation and Subsidiaries maintained effective internal control over financial reporting as of December 31, 2005, based on criteria established in Internal Control
 Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Deltic Timber Corporation and Subsidiaries management is responsible for maintaining effective internal control over financial
reporting and for its assessment of the effectiveness of internal control over financial reporting. Our responsibility is to express an opinion on managements assessment and an opinion on the effectiveness of the Companys internal
control over financial reporting based on our audit.

We conducted our audit 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 effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining
an understanding of internal control over financial reporting, evaluating managements assessment, testing and evaluating the design and operating effectiveness of internal control, and performing such other procedures as we considered
necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A companys internal control over financial
reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A
companys internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the
assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of
the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the
companys assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial
reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance
with the policies or procedures may deteriorate.

In our opinion, managements assessment that Deltic Timber Corporation and Subsidiaries maintained
effective internal control over financial reporting as of December 31, 2005, is fairly stated, in all material respects, based on criteria established in Internal Control  Integrated Framework issued by the Committee of Sponsoring
Organizations of the Treadway Commission (COSO). Also, in our opinion, Deltic Timber Corporation and Subsidiaries maintained, in all material respects, effective internal control over financial reporting as of December 31, 2005, based on
criteria established in Internal Control  Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of Deltic Timber Corporation and Subsidiaries as of December 31, 2005 and 2004,
and the related consolidated statements of income, comprehensive income, stockholders equity , and cash flows for each of the years in the three-year period ended December 31, 2005, and our report dated March 7, 2006 expressed an
unqualified opinion on those consolidated financial statements.

Item 9A. Controls and Procedures

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.

Based on their evaluation as of December 31, 2005, the Chief Executive Officer and Chief Financial Officer of the Company have concluded that the
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
files or submits under the Securities Exchange Act of 1934 is recorded, processed, summarized, and reported within the time periods specified in SEC rules and forms.

Managements Report on Internal Control Over Financial Reporting

The Companys
management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rules 13a-15(f). Under the supervision and with the participation of management, including the
principal executive officer and principal financial officer, Deltic conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework in Internal Control  Integrated Framework issued by the
Committee of Sponsoring Organizations of the Treadway Commission. Based on evaluation under the framework in Internal Control  Integrated Framework, management concluded that internal control over financial reporting was effective as of
December 31, 2005. Managements assessment of the effectiveness of our internal control over financial reporting as of December 31, 2005 has been audited by KPMG LLP, an independent registered public accounting firm, as stated in
their report which is included herein.

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 (the Companys fourth quarter in the case of an annual report), 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.

Report of Independent Registered Public Accounting Firm

The Board of Managers

Del-Tin Fiber L.L.C.:

We have audited the accompanying balance sheets of Del-Tin Fiber L.L.C. as of December 31, 2005 and January 1, 2005, and the related statements of operations,
cash flows, and members capital for each of the fiscal years in the three-year period ended December 31, 2005. These financial statements are the responsibility of the Companys management. Our responsibility is to express an opinion
on these financial statements based on our audits.

We conducted our audits 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. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We
believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all
material respects, the financial position of Del-Tin Fiber L.L.C. as of December 31, 2005 and January 1, 2005, and the results of its operations and its cash flows for each of the fiscal years in the three-year period ended
December 31, 2005, in conformity with U.S. generally accepted accounting principles.

Our audits were made for the purpose of forming an opinion on
the basic financial statements taken as a whole. The supplementary information included in Schedule 1 is presented for purposes of additional analysis and is not a required part of the basic financial statements. Such information has not been
subjected to the auditing procedures applied in the audits of the basic financial statements and, accordingly, we express no opinion on it.

Note 1  Summary of Significant Accounting Policies

Description of Business

Del-Tin Fiber L.L.C. (Del-Tin or the Company) is an
Arkansas limited liability company organized in February 1995 and is equally owned by Temple-Inland Forest Products Corporation (Temple-Inland), a Delaware corporation, and Deltic Timber Corporation (Deltic), a Delaware
corporation. Del-Tin is to exist until December 31, 2024, unless the Company is earlier dissolved in accordance with either the provisions of the Operating Agreement or the Arkansas Small Business Entity Tax Pass Through Act. The business of
the Company is to manufacture, distribute, and sell medium density fiberboard (MDF) under the trade name Solidium. Within the United States, MDF is sold primarily to manufacturers and distributors of laminated flooring,
furniture, cabinets, fixtures, and moulding. Temple-Inland and Deltic share equally in revenue, expenses, and funding requirements of the joint venture.

Under the terms of a separate Fiber Supply Agreement, Deltic will be the preferred supplier of wood fiber, consisting of sawdust, shavings, and chips. Del-Tin will purchase the majority of residual chips produced by
Deltics Waldo, Arkansas sawmill at a delivered price that approximates the weighted average delivered price of like-kind residual chips available to Del-Tin from third parties in the area. Del-Tin will also have first call on residual chips
from Deltics sawmill in Ola, Arkansas.

Under the terms of a separate MDF Marketing Agreement, Temple-Inland will serve as the
exclusive marketing agent for all MDF produced at the facility for a period of five years from the first day of production of MDF, which was in June 1998. The MDF Marketing Agreement shall be automatically extended for successive five-year periods
unless either party elects not to extend.

Accounting Period

The Companys fiscal year is the 52 or 53-week period ending the Saturday closest to December 31. Fiscal years 2005, 2004, and 2003, ended on
December 31, 2005, January 1, 2005, and January 3, 2004, respectively. Reference to years in these financial statements relate to fiscal years rather than calendar years.

Cash and Cash Equivalents

The Company considers short-term investments with a remaining maturity of three months or less at the date of purchase to be cash equivalents.

Inventories

Inventories are stated at the lower of cost or market. Cost is determined using the weighted average method for all inventories.

Property, Plant, and Equipment

Property, plant, and equipment is stated at cost less accumulated
depreciation. Depreciation of buildings, machinery and equipment, and other depreciable assets is calculated over the estimated useful lives of the assets by using the units of production method for machinery and equipment and the straight-line
method for all other depreciable assets. The estimated useful lives for property, plant, and equipment, excluding machinery and equipment, are as follows:



|                  |  |             
|----------------- |  | ------------
|Buildings         |  | 40 years    
|Land improvements |  | 20 years    
|Vehicles          |  | 3 to 5 years

Notes to Financial Statements

December 31, 2005

Note 1  Summary of Significant Accounting Policies (continued)

Routine maintenance and repairs are charged to operating expense, while costs of equipment upgrades and replacements are capitalized. When an asset is retired or sold, its cost and related accumulated depreciation are
removed from the accounts and the difference between the net book value of the asset and proceeds from disposition is recognized as a gain or loss.

Long-lived assets are accounted for under Statement of Financial Accounting Standards (SFAS) 144, Accounting for the Impairment or Disposal of Long-Lived Assets.The Company assesses impairment losses on long-lived assets used in
operations when events and circumstances indicate that the assets might be impaired and the estimated undiscounted cash flows to be generated by those assets are less than the carrying amounts of those assets. Impairment losses are recognized if the
estimated fair value of the assets is less than its carrying value. The Company recorded no such impairment in 2005, 2004 or 2003.

Revenue Recognition

Revenue from the sale of products is recognized upon passage of title to the
customer, which is at the time of shipment.

Income Taxes

Because the Company is a limited liability company, it has the option of being taxed as a partnership or a corporation. The Company elected to be taxed as
a partnership and as such is not subject to income taxes at the Company level. All taxes are recognized by the members of the Company.

Impact of Recent Accounting Pronouncements

In November 2004, the FASB release SFAS 151, Inventory
Costs, which requires abnormal amounts of idle facility expense, freight, handling costs, and wasted material (spoilage) to be recognized as current-period charges. It also requires that allocation of fixed production overheads to the costs of
conversion be based on the normal capacity of the production facilities. SFAS 151 is effective for inventory costs incurred during fiscal years beginning after June 15, 2004. The adoption of SFAS 151 did not have a material effect on the
Companys financial statements.

In December 2004, the FASB issued SFAS 153, Exchanges of Nonmonetary Assets,an amendment of
Accounting Principles Board (APB) Opinion No. 29. This statement amends APB 29 concerning the accounting for exchanges of similar productive assets. These transactions will now be accounted for at fair value, the basic principle of nonmonetary
transactions, unless the exchange lacks commercial substance. This statement is effective for nonmonetary asset exchanges occurring in fiscal periods

beginning after June 15, 2005. The Company does not expect the adoption of SFAS 153 to have a material effect on its consolidated financial statements.

Notes to Financial Statements

December 31, 2005

Note 1  Summary of Significant Accounting Policies (continued)

In March 2005, the FASB issued Financial Accounting Standards Board Interpretation (FIN) No. 47, Accounting for Conditional Asset Retirement Obligations.This interpretation clarifies the term
conditional asset retirement obligation as used in SFAS 143, Accounting for Asset Retirement Obligations,and is effective no later than the end of fiscal years ending after December 15, 2005. The adoption of FIN 47 did not
have a material effect on the Companys financial statements.

In May 2005, the FASB issued SFAS 154, Accounting Changes and Error
Corrections.This statement requires all changes in accounting principles to be accounted for by retrospective application to the financial statements for prior periods unless it is impracticable to do so. SFAS 154 carries forward previously
issued guidance with respect to accounting for changes in estimates, changes in the reporting entity and the correction of errors. This statement is effective for accounting changes made in fiscal years beginning after December 15, 2005. The
Company will consider this in future years, as applicable.

Use of Estimates

Management of the Company has made a number of estimates and assumptions, relating to the reporting of assets and liabilities and the disclosure of
contingent assets and liabilities, to prepare these financial statements in conformity with accounting principles generally accepted in the United States of America. Actual results could differ from those estimates.

Reclassifications

Certain prior year amounts have been reclassified to conform with the 2005 presentation format.

Note 2  Liquidity

Prior to 2004, the Company had incurred continued significant operating losses and accordingly required substantial financial support from its members.
While management anticipates profitable operations in future years, continued support from the members may be required to ensure the Company is able to meet its obligations as they become due. The members have committed to provide such support to
the Company if needed.

Note 3  Inventories

Inventories at year-end consisted of the following:

The Bonds

In December 1998, the Bonds were issued by Union County, Arkansas, in the amount of $60,000,000, to finance the completion of the construction of the
Companys MDF plant, as well as the acquisition, construction, and improvement of certain sewerage and solid waste disposal facilities related to the Companys MDF plant. Neither the State of Arkansas nor Union County, Arkansas have any
liability

under the Bonds. The Company and Union County contemporaneously entered into a lease agreement (the Lease Agreement) that obligated the Company to make lease payments in an amount necessary to fund the
debt service on the Taxable Bonds. The Bonds were payable solely from the proceeds of the letters of credit issued to support the respective Bonds and from company payments under the Loan Agreement and the Lease Agreement with Union County,
Arkansas. The Company has also unconditionally guaranteed the payment of all amounts owing under the Bonds to the bondholders. The Companys indebtedness has been presented in these financial statements as though the Company was directly liable
for the Bonds. If the bonds are not remarketed as allowed under the agreement, the letters of credit and the commitment of the Lenders are available to support repayment.

The Bonds currently bear interest at a variable rate determined weekly by the remarketing agent of the respective Bonds. Interest is due on the first business day of the month, and all unpaid interest and all
principal is due on October 1, 2027. The interest rate on the Taxable Bonds at year-end 2005 was

4.35 percent and 2.4 percent in 2004.

As a result of the Companys debt refinancing on August 26, 2004, $31,000,000 of these bonds were retired on September 1,
2004, with the Lease Agreement remaining in place.

The Credit Facility

On August 26, 2004, the Company entered into a Letter of Credit and Term Loan Agreement (Credit Agreement) with SunTrust Bank and a group
of other domestic banks (the New Lenders), in order to refinance a portion of the Companys existing debt. Under the new Credit Agreement, the New Lenders, on August 26, 2004, loaned Del-Tin $30,000,000 which is repayable over
five years in equal quarterly installments, beginning in the fourth quarter of 2004. The funds provided from this term note were used, together with the existing balance in the Companys debt service reserve and bond sinking fund accounts, to
retire, in their entirety, the 1997 Series A and Series B revenue bonds, and $31,000,000 of the outstanding Taxable Bonds. In addition, under the Credit Agreement a letter of credit in the amount of $29,689,000 was issued on the Companys
behalf to support the remaining balance of the Taxable Bonds of $29,000,000. This letter of credit commitment expires on August 25, 2007. Consistent with the previous Credit Facility, under the new debt facility, substantially all of the
Companys assets are pledged to the New Lenders as security for the Credit Agreement.

However, under the new Credit Agreement, the
Company is not required to maintain debt service reserve funds or sinking fund balances. The Credit Agreement contains customary terms and conditions, including certain representations and warranties, and affirmative and negative non-financial
covenants.

As further security for the new Credit Agreement, each member has executed a guarantee agreement unconditionally guaranteeing,
as a primary obligor and not merely as a surety, the due and punctual payment of Del-Tins obligations under the new Credit Agreement. Accordingly, all previous member guarantee agreements under the prior Credit Facility were terminated.

Scheduled maturities of long-term debt for the next four years are, $6,000,000 in 2006, $6,000,000 in 2007, $6,000,000 in 2008, and
$4,500,000 in 2009.

Note 5  Indebtedness and Financing Arrangements (continued)

Upon the refinancing of the Companys previous Credit Facility, all unamortized debt issuance cost not relating to the remaining outstanding Taxable Bonds, in the amount of $216,709, were expensed in 2004 and
reflected as a loss on extinguishment of debt. In connection with the new Credit Agreement, the Company incurred approximately $457,082 in related costs, which have been included in the balance sheet in deferred debt costs and are being amortized to
interest and other debt expense on a straight-line basis, which approximates the effective interest method, over the life of the new Credit Agreement.

The Company is subject to certain restrictive covenants in connection with the Bonds and its Credit Facility and was in compliance with such covenants as of December 31, 2005 and January 1, 2005.

Note 6  Fair Value of Financial Instruments

The following table presents the carrying amounts and estimated fair values of the Companys financial instruments at year-end 2005 and 2004. The fair value of a financial instrument is the amount at which the instrument could be
exchanged in a current transaction between willing parties.

The carrying amounts shown in the table are included in the balance sheets under the indicated
captions.

The following methods and assumptions were used to estimate the fair value of each class of financial instruments:



| |  |  | Cash and cash equivalents, trade accounts receivable, other receivables, bank overdraft, accounts payable, and accrued expenses  The carrying amounts approximate fair value
because of the short maturity of these instruments.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Long-term debt  The carrying amount approximates fair value since the interest paid fluctuates with changes in current market rates.

Note 10  Deltic Investment

In January 2003,
citing reasons that the MDF business no longer represented a growth area for them and consequently that they intended to exit the business upon the earliest, reasonable opportunity, Deltic evaluated its investment in Del-Tin and determined it to be
impaired. As a result, Deltic wrote off its entire investment in Del-Tin, amounting to $18.7 million, based on estimated fair value of the investment. This assessment differed from the Companys evaluation of the recoverability of the property,
plant, and equipment under SFAS 144. Deltic had committed to provide continued support

until such time as its ownership was sold.

During 2003, Deltic and Temple-Inland continued to use management resources to improve operating performance at Del-Tin. As a result of
these improvements, on December 11, 2003, Deltics Board of Directors revised its intent regarding its investment in Del-Tin and discontinued efforts to sell their interest while continuing to focus on improving operating and financial
results of Del-Tin.

Note 11  Involuntary Conversion

On January 16, 2005, a fire occurred in the fiber storage area of the plant and spread to the forming area causing severe damage to plant and equipment. Production was suspended during the period of restoration.
The plant resumed operations on February 9, 2005. The cost of the physical damage, business interruption, and extra expense was $4,829,454. After deductible of $1,000,000, the amount of the insurance claim and proceeds received during 2005 was
$3,829,454. The gain on the involuntary conversion of nonmonetary assets to monetary assets received was $890,365 and is reflected in the Companys 2005 statement of operations as net loss/(gain) on asset dispositions. The insurance proceeds
from business interruption and reimbursement of expenses was $737,460 and $646,706, respectively, and is reflected in the Companys 2005 statement of operations as cost of sales.

Note 12  Contingencies

During 2005, Del-tin was contacted by the Internal Revenue Service
(IRS) in relation to their efforts to contest tax exempt status of bonds issued by several manufacturing companies, such tax exempt status being dependent upon proceeds of the bonds being used to construct waste disposal energy systems as defined by
the IRS. Rather than pursuing related taxes from the bondholders, the IRS is pursuing monies from the issuers of the bonds. This issue is related to the Companys 1997 tax-exempt bonds, which were paid off in 2004.

The Company has engaged in settlement discussions with the IRS and, based on the status of those discussions and the Companys analysis of its
ultimate exposure in this matter, the Company has accrued $312,000, which represents the Companys estimate of the probable liability to be incurred. The expense is reflected in the Companys 2005 statement of operations as estimated
tax-exempt issue settlement and in the year-end 2005 balance sheet in accrued expenses.

Upon reaching a settlement with the IRS, which is
expected in the first half of 2006, the bonds would remain classified as tax exempt and the bondholders would not be liable for any related income taxes.
