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.  The Company owns
approximately 444,000 acres in Arkansas and north Louisiana, including 397,000
acres of timberland (the "timberlands").  Sawmill operations consist of two
mills, one at Ola in central Arkansas and another at Waldo in south Arkansas.

     In addition to its timber and lumber operations, Deltic is engaged in real
estate development projects in central Arkansas and owns approximately 37,000
acres of farmland in northeast Louisiana. The Company also holds a 50 percent
interest in a joint venture to manufacture and market medium density fiberboard
("MDF"), which began production operations in April 1998.

     Deltic believes that its primary strengths are its strategically located
timberlands, its efficient sawmill operations, its well-established real estate
developments, its experienced management team, and its capacity to pursue a
timber-based acquisition strategy.

     The timberlands consist primarily of 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.  Estimated pine
sawtimber inventory as of December 31, 1998 was 9,603,000 tons. The southern
United States, in which all of the Company's operations are located, is a major
timber and lumber producing region.  Unlike other major timber-producing areas
in North America, most timber acreage in the southern United States is privately
held, rendering it potentially available for acquisition. Deltic's current
growth strategy emphasizes a significant timberlands acquisition program in such
region, which has facilitated an increase in harvest levels.

     The Company harvests timber from the timberlands in accordance with its
harvest plans and either sells timber in the domestic market or converts timber
to lumber in its sawmills.  In 1998, Deltic harvested approximately 431,600 tons
of pine sawtimber from its timberlands.  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 quality standards of
production.  In addition, each sawmill is strategically located near significant
portions of the timberlands.  During 1998, Deltic's sawmills produced
approximately 159.7 million board feet of lumber.  Logs processed for the
production of lumber are obtained from the timberlands and from public and
private landowners.  The Company selects logs for processing in its sawmills
based on size, grade, and the then 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.  Approximately $31.6 million
has been invested in upgrades of the two sawmills over the past five years,
expanding both production capacity and product lines.  Combined annual capacity
is currently 226 million board feet.  The Company's sawmills produce a variety
of products, including dimension lumber, boards, timbers, decking, and secondary
manufacturing products such as finger-jointed studs.  The lumber is sold
primarily to wholesalers and treaters in the South and Midwest and is used in
residential construction, roof trusses, laminated beams, and remanufactured
items.

                                       3

     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 a 4,800-acre
premier upscale planned community, Chenal Valley, centered around a Robert Trent
Jones, Jr. designed golf course at Chenal Country Club.  The property is being
developed in stages, and real estate sales to date have consisted primarily of
residential lots.  Commercial development began in 1996.

     In addition to Chenal Valley, Deltic is developing Chenal Downs, a 400-acre
equestrian development located outside of Chenal Valley being sold in estate-
sized lots of approximately five acres each with controlled access, and Red Oak
Ridge, Deltic's first real estate development outside of the Little Rock/Pulaski
County area.  The first phase of lot sales in Chenal Downs was offered in
December 1997, with 25 of the 44 lots offered sold as of the end of 1998.  Red
Oak Ridge, located near Hot Springs, Arkansas, is an 800-acre, upscale community
designed for residential, resort, or retirement living.  The first two
neighborhoods in this development, offering a choice of either estate-sized
homesites, with many overlooking one of the two lakes, or lots in a garden-home
neighborhood, were offered for sale in late 1998.

     The Company owns 37,000 acres of farmland in northeast Louisiana.
Approximately 26,000 acres of the total are farmed by Deltic, while the majority
of the remaining 11,000 acres is rented to third parties.  Crops grown on
Company-farmed acreage in 1998 were soybeans and corn.

     Deltic owns 50 percent of the membership interest of Del-Tin Fiber, L.L.C.
("Del-Tin Fiber"), a joint venture to manufacture and market medium density
fiberboard. The Del-Tin Fiber plant is located near El Dorado, Arkansas.
Construction of this facility commenced in mid-1996 and initial production began
on April 29, 1998. MDF, which is used in the furniture, flooring, and molding
industries, is manufactured from sawmill residuals, such as chips, shavings, and
sawdust, held together by an adhesive bond. The plant is designed to have an
annual production capacity of approximately 150 million square feet, 3/4" basis,
making it one of the largest of its type in the world. The plant also adds value
to Deltic's operations by providing an additional outlet for wood chip and bark
production from the Waldo Mill. During 1998, Deltic sold approximately
$2,126,000 of these lumber manufacturing by-products to Del-Tin Fiber.

FOREST PRODUCTS

     The demand for, and prices of, timber and manufactured wood products depend
on the level of housing starts, repair and remodeling activity, industrial
construction activity, competition from non-wood products, and seasonal factors
such as weather. These factors in turn are strongly influenced by overall
economic activity, interest rates, and demographics. Reductions in levels of
construction activity are generally followed by declining lumber prices, which
are ordinarily followed by declining timber prices within several months.
However, despite strong economic conditions and housing starts in the U.S.
during 1998, a downturn in Asian export markets caused the North American lumber
market to be oversupplied for much of 1998. Lumber that was normally exported
from North America to Asia was redirected to U.S. markets, causing supply to
outpace demand and depressing prices. However, demand for timber, as well as
timber prices, remained relatively strong during 1998.

     The supply of timber, and therefore lumber, is significantly affected by
the availability of timber from public lands, particularly in the Pacific
Northwest. In recent years, the U.S. government has dramatically reduced the
amount of timber offered for sale in response to environmental concerns. This
has resulted in increased demand for timber in the southern U.S., as well as
increased lumber imports from Canada.

                                       4

     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 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 in the 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 397,000 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 breakdown of the Company's timberland acreage at year-end 1998 consisted of
the following:

     Timber Inventory.  The Company's estimated standing timber inventory on
this acreage 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 or actual volumes harvested from related
tracts.  The hardwood inventory shown in the following table is only an
approximation, so physical quantity of such timber may vary significantly from
this approximation.  Estimated inventory of standing timber as of December 31,
1998 consisted of the following:

</TABLE>

     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 manufacturing 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. 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 for Deltic's Southern Pine is on
average, net of mortality, 5 percent to 5 1/2 percent of standing inventory per
annum.

     The Company's timberlands are well diversified by age distribution. A
significant portion of the timberlands contains mature timber that is ready to
be harvested in the next several years. The Company considers a 30 to 35 year
rotation optimal for most of the timberlands. Timber under 15 years of age is
generally considered premerchantable.

     Access.  Substantially all of the timberlands are accessible by a system of
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.

     Reforestation.  Deltic has developed and operates its own seed orchard.
Seeds from the orchard are grown by third parties to produce genetically-
superior 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. The seedlings are planted in all-aged stands or a site is completely
replanted with these superior seedlings in the case of a regeneration harvest.
During 1998, 2,800 acres were planted using seedlings grown from seeds produced
at the orchard facility. This level is expected to accelerate significantly with
approximately 6,000 acres scheduled for reforestation in 1999, as the Company's
land acquisition program continues. The Company meets or exceeds, in all
material respects, the reforestation recommendations of the Arkansas Forestry
Commission's Best Management Practices.

     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 at levels that exceed growth. Under the current
plan, Deltic intends to increase its harvest level to 445,000 tons of pine
sawtimber in 1999, an increase of three percent over 1998 levels. (See "Growth
Strategy".)

     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, which are reviewed monthly and revised at least
annually, are sufficiently flexible to permit modification in response to
fluctuations in the markets for logs and lumber.

     Timber Resource Management.  The Company's timber operations involve forest
management, harvesting operations, and ongoing reforestation. Forest management
decisions are based upon information which includes site indices, classification
of soils, the species and number of trees by size and age classification, and
stocking per acre, as well as information on forest management costs. From this
data, Deltic develops its annual harvest plans, which are based upon
silvicultural considerations and existing and expected future economic and
market conditions, with a view toward maximizing the value of its timber and
timberland assets over time.

                                       6
<PAGE>
 
     Particular forestry practices vary by geographic region and depend upon
factors such as soil productivity, weather, terrain, tree size, age, and timber
stocking. Forest stands are thinned periodically, to improve growth and stand
quality, until they are harvested. Different areas within a forest may be
planted or seeded in successive years to provide a distribution of age classes
within the forest. This distribution of age classes will tend to provide Deltic
with an annual revenue stream, as the various timber stands reach harvestable
age.

     The timing of harvest of merchantable timber depends in part on growth
cycles and in part on economic conditions. Growth cycles for timber tend to
change over time as a result of technological and genetic advances that improve
forest management practices. The Company will continue to develop its forest
management operations to take advantage of such advances and improve timber
yields.

     The Company actively utilizes commercial-thinning timber management
practices.  In the context of long-term value maximization, commercial thinning
improves the overall productivity of the timberlands by enhancing the growth of
the remaining trees while generating revenues.

     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 provides harvest planning, silvicultural
improvements, and maintenance work for approximately 79,000 acres.

SAWMILLS

     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 Ola
Mill is equipped for maximum utilization of smaller diameter logs, while the
Waldo Mill can process both smaller and larger diameter logs. Approximately
$31.6 million has been invested in the two sawmills over the past five years,
expanding both production capacity and product lines. Combined annual capacity
at December 31, 1998 was 226 million board feet.

     Deltic employs modern technology in its sawmills in order to improve
overall efficiency, reduce labor costs, and maximize utilization of available
timber resources, while continuing to maintain high quality standards for lumber
production.  The Company continues to upgrade and expand its sawmills to
increase production capacity and diversify the product mix offered.

     During 1998, the Ola Mill completed installation of a new boiler system and
an additional kiln. These capital projects increased the annual lumber drying
capacity of this mill to 100 million board feet. A small log processing deck was
placed into service in the second quarter of 1998, allowing the extraction of
small diameter logs from pulpwood to facilitate log supply and reduce log cost.
The Company also began the construction of a new planermill, an automated lumber
sorting system, and an optimized edger system to further increase both
production capability and efficiency at this facility in order to increase
profitability.  These improvements are expected to be completed during the first
half of 1999.

     The Waldo Mill's finger-jointing operation completed its first year of
operation in 1998 with 3.7 million board feet of production. This secondary
manufacturing operation adds value to Waldo's planermill operation by using
short, trim pieces to manufacture finger-jointed studs, an addition to the
product sales mix, instead of selling these pieces at low prices, thus enhancing
the mill's sales price average. Residual by-products from the Waldo Mill are now
being used by Del-Tin Fiber in the production of medium density fiberboard. The
Company is committed to increased utilization of modern technology at its mills
during 1999, an example of which is the planned addition of a new log
optimization

                                       7

system at the Waldo Mill.  With the completion of installation of this optimized
log bucking system, the Waldo Mill will have been upgraded from its log deck to
its lumber sorting system, which is expected to result in additional production
cost savings for this mill.

     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.  In the future, the Company expects to sell a more significant portion of
its Waldo Mill's residual wood chip production to Del-Tin Fiber pursuant to a
fiber supply agreement.

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

     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.

GROWTH STRATEGY

     The Company's current strategy for growth continues to emphasize a
significant timberland acquisition program, which has facilitated an increase in
its harvest levels, and the expansion of its manufacturing operations.

     Timberland Acquisitions.  The Company's ongoing timberland acquisition
program will enable it 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 it is economically feasible.

     Timberland acquisitions are necessary for continued growth in harvest
levels over the long-term. The Company intends to continue to focus its
acquisition program on timberlands in the southern United States that range from
fully-stocked to cutover tracts, with preference given to stocked acreage.
Timberland in the southern United States is 89 percent owned by private
landowners, rendering 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.

     Acting upon this strategy of timberland acquisition, Deltic formed a land
acquisition team. Lands considered for purchase were evaluated based on
location, site index, timber stocking, and growth potential. As a result,
approximately 58,600 acres, 30,400 in 1998, of strategically located pine
timberland have been added since the inception of the acquisition program in
late 1996. Individual land purchases ranged from 10 acres to 16,300 acres, with
the average block to-date being 413 acres. The major acquisition in 1998 was the
former McKinney lands in south Arkansas, consisting of 16,300 acres of heavily-
stocked timberland.

     Manufacturing Operations.  Recent capital projects at the Company's two
sawmills have expanded both production capacity and product mix. Future projects
are expected to continue to increase production levels, add value to existing
production, expand secondary manufacturing operations, improve lumber recovery,
and decrease manufacturing costs. The Company plans to increase lumber
production to 210 million board feet in 1999, an increase of 32 percent over the
1998 level.

                                       8
<PAGE>
 
     The Company's 50 percent interest in Del-Tin Fiber will enable it to expand
its business into the engineered wood products market. Del-Tin Fiber is a joint
venture to manufacture and market MDF. The plant is located near El Dorado,
Arkansas. The construction cost of the facility was approximately $100 million.
Construction commenced in mid-1996 and initial production began on April 29,
1998. The plant is designed to have an annual production capacity of 150 million
square feet, 3/4" basis, making it one of the largest of its type in the world.
MDF, which is used 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 "real wood" appearance and ability
to be finely milled and accept a variety of finishes, competes primarily against
lumber. In addition to providing an entry into the MDF market, the Del-Tin Fiber
project will provide an outlet for a significant portion of the Company's wood
chips. Pursuant to a fiber supply agreement, the Company has agreed to sell, and
Del-Tin Fiber to buy, 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.

RAW MATERIALS

     Logs processed by the Company's two sawmills in 1998 totaled 795,700 tons,
and were obtained from either the timberlands or purchased from public and
private landowners.  Of the 431,600 tons of pine sawtimber harvested from the
timberlands in 1998, 203,500 tons, 47 percent, were processed in the Company's
two sawmills.

     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 department
for each of its sawmills. As of December 31, 1998, the Company had under
contract approximately 469,900 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 1998, the Company harvested third-party stumpage and
purchased logs from third parties totaling 583,100 tons. Of this volume,
purchases from the U.S. Forest Service during this period represented 12
percent. The balance of such purchases was acquired from private lands.

     As a result of the reduced availability of federal timber, demand for
privately-owned timber has increased, along with prices; 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.

PRODUCTS AND COMPETITION

     The Company's principal forest products are timber; lumber products,
primarily finished lumber; and residual wood products.

     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 12 percent, 14 percent, and 16 percent of
consolidated net sales in 1996, 1997, and 1998, 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 consuming facilities, and the ability to meet delivery
requirements.

     Lumber Products.  The Company's sawmills produce a wide variety of
products, including dimension lumber, boards, timbers, decking, and secondary
manufacturing products such as finger-jointed studs. Lumber is sold primarily to
wholesalers and treaters in the South and Midwest and is used in residential
construction, roof trusses, laminated beams, and remanufactured items. During
1996, 1997, and 1998, lumber sales as a percentage of consolidated net sales
were approximately 55 percent, 57 percent, and 52 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
Arkansas, many of which have significantly greater financial resources than the
Company, as well as privately-held lumber producers. In addition, Deltic's
management expects the Company's products to experience 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.

     Chips.  The Company's sawmills produce wood chips as by-products of the
applicable conversion process. Chips are typically sold to Del-Tin Fiber or to
paper mills. During 1998, Deltic's sawmills produced 289,400 tons of wood chips.
During 1996, 1997, and 1998, sales of wood chips and other by-products of the
Company's sawmills accounted for 11 percent, eight percent, and nine percent,
respectively, of Deltic's consolidated net sales. In the future, the Company
expects to continue to sell a significant portion of certain of its residual
wood products to Del-Tin Fiber for the production of MDF. (See "Growth
Strategy".)

REAL ESTATE OPERATIONS

     Deltic's Real Estate operations in Chenal Valley 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 a
4,800-acre premier upscale planned community, Chenal Valley, centered around a
Robert Trent Jones, Jr. designed golf course. The golf course was completed in
1990. The property has been developed in stages and real estate sales to date
have consisted primarily of residential lots, with commercial development
beginning in 1996.

     In connection with its Chenal Valley development, the Company developed
Chenal Country Club, consisting of the above-described golf course, a clubhouse,
and related facilities for use by club members; and the club membership agreed
to purchase Chenal Country Club with payments to be made on specified terms
through 1999.  During 1997, the agreement was restructured in order to return
ownership of Chenal Country Club to the Company with the club members making
ongoing membership

                                       10
<PAGE>
 
fee payments. In connection with the restructuring, Deltic agreed to undertake
substantial remodeling and expansion of the clubhouse. (For additional
information, see Note 4 to the consolidated financial statements in Item 8,
"Financial Statements and Supplementary Data", of Part II of this report.)

     Commercial development began in 1996 with the construction of a Deltic-
owned, 50,000 square-foot office building, approximately one-half of which is
leased to a national, financial servicing company. During 1997, commercial sales
activity increased, with more than 26 acres sold for multi-family development.
However, during 1998, commercial acres sold was approximately eight acres.  Site
work for a Deltic-owned retail center began in 1997, and in 1998, Deltic began
construction of the 35,000-square-foot center which will offer retail space for
lease and will be completed during 1999. Construction of Rahling Road, a major
connector street that provides access to Chenal Valley's commercial core, began
in 1997 and was completed in early 1998.  Commercial sites along this street,
increased residential development, and additional infrastructure investment are
expected to result in increased commercial activity.

     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 all infrastructure is completed.  Future
infrastructure investments are necessary only for the development and sale of
additional property.

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

     When fully developed, Chenal Valley will include approximately 4,700
residential homesites. To date, 1,350 homesites have been developed and 994 lots
sold, with about 850 residences constructed or under construction. Of its 635
total commercial acres, Chenal will offer acreage for office tracts, multi-
family development, and retail locations. The development plan supports the
area's growing demand for corporate and service-oriented products.

     In addition to Chenal Valley, Deltic is developing Chenal Downs, a 400-acre
equestrian development located outside of Chenal Valley being sold in estate-
sized lots of approximately five acres each, and Red Oak Ridge, Deltic's first
real estate development outside of the Little Rock/Pulaski County area.  The
first phase of lot sales in Chenal Downs was offered in December, 1997, with 25
of the 44 lots offered sold as of the end of 1998.  Red Oak Ridge, located at
Hot Springs, Arkansas, is an 800-acre, upscale community designed for
residential, resort, or retirement living.  The first two neighborhoods in this
development, offering a choice of either estate-sized homesites, with many
overlooking one of two lakes, or lots in a garden-home neighborhood, were
offered for sale in late 1998.

AGRICULTURE OPERATIONS

     Deltic owns 37,000 acres of farmland in northeast Louisiana.  Approximately
26,000 acres of the total are farmed by Deltic, while the majority of the
remaining 11,000 acres are rented to third parties. Crops grown on Company-
farmed acreage in 1998, and planned for 1999, were soybeans and corn.

     The installation of two continuous-flow drying systems in 1997 allowed more
than 55 percent of Deltic's 1998 corn production to be dried before delivery to
local markets, which meant lower harvest losses and reduced drying charges from
grain elevator operators.  The purchase of additional new

                                       11
<PAGE>
 
combines allowed Deltic to continue to harvest crops at optimum grain moisture
and field conditions, rather than having to rely on the availability of custom
harvesters.

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 stronger timber prices. Increased housing starts during the
spring usually push lumber prices up and, in turn, can result in higher timber
prices. Forestry operations generally incur expenses related to silvicultural
treatments which are applied during the fall season to achieve maximum
effectiveness. Farming operations generally do not generate significant sales
and operating income until crops are harvested and sold in the second half of
the year.

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 20 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 1998, the
Company acquired approximately 20 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 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 pesticides and herbicides on the farm and 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
currently 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.

                                       12
<PAGE>
 
     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.

EMPLOYEES

     As of February 28, 1999, the Company had 500 employees.


ITEM 2.  PROPERTIES

     The Company's properties, primarily located in Arkansas and north
Louisiana, consist principally of fee timber and timberlands, purchased stumpage

ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
         AND RESULTS OF OPERATIONS


OVERVIEW

     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. The Company owns approximately 397,000
acres of timberland 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 and owns approximately 37,000 acres of farmland in northeast Louisiana.
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,
which began production in April 1998.

     On November 11, 1996, the Board of Directors of Murphy Oil Corporation
("Murphy Oil") declared a dividend payable to holders of record of Murphy Common
Stock at the close of business on December 2, 1996 (the "Record Date") of one
share of Deltic Common Stock for every 3.5 shares of Murphy Common Stock owned
of record on the Record Date. As a result, 100 percent of the outstanding shares
of Company Common Stock was distributed to Murphy Oil shareholders on December
31, 1996 (the "Distribution Date"). Prior to the Distribution Date, the Company
was operated as part of Murphy Oil. The financial information for the year of
1996, presented herein, reflects a period during which the Company did not
operate as an independent company. Such information, therefore, may not
necessarily reflect the results of operations or the financial condition of the
Company which would have resulted had the Company been an independent, public
company during that reporting period, and are not necessarily indicative of the
Company's future operating results or financial condition.

     The Company's results of operations are affected primarily by the cyclical
supply and demand factors of the forest products industry. Despite strong
economic conditions and housing starts in the U.S., the downturn in Asian
markets caused the North American lumber market to be oversupplied for much of
1998. Lumber that was normally exported from North America to Asia was
redirected to U.S. markets, causing supply to outpace demand and depressing
prices. However, demand for timber, as well as timber prices, remained
relatively strong during 1998. While beneficial to the Company's Woodlands
segment, strong timber prices combined with depressed lumber prices negatively
impacted the performance of the Mills segment. Other factors impacting operating
results of the Company include interest rates, commodity prices, adverse
weather, and general economic conditions.


RESULTS OF OPERATIONS

     Consolidated net income for 1998 was $8.5 million, $.48 a share, compared
to $16.6 million, $1.29 a share, for 1997.  The decrease was primarily the
result of lower operating income from the Company's Mills and Agriculture
segments combined with a $4.6 million loss for the Company's share of equity in
Del-Tin Fiber's plant start-up costs incurred to-date and operating losses
reported since initial production commenced in late April 1998.  In 1996, the
Company earned $13.2 million, $1.03 a share on a pro forma basis.

     Operating income for 1998 decreased $7.3 million to $18.3 million.  The
Woodlands segment increased $2.5 million due primarily to a 21 percent increase
in pine sawtimber harvest levels, partially offset by a four percent decrease in
the average price for pine sawtimber sold.  The Company's Mills segment
operating results decreased $10.2 million as the result of a $53 per thousand
board feet ("MBF") drop in the average lumber sales price and a five percent
higher cost of production per MBF 

                                       17
<PAGE>
 
sold, which caused a negative margin per MBF. Real Estate operations increased
$1.8 million and benefited from a 55 percent increase in the number of
residential lots sold. The Agriculture segment decreased $2 million as the
result of reduced sales prices for soybeans and corn in 1998, combined with 1997
benefiting from the timing of sales of soybeans grown during 1996.

     In 1997, operating income increased $7.6 million to $25.6 million. The
Company's Woodlands operations increased $5.5 million as the result of a 20
percent rise in the average price for pine sawtimber sold coupled with a 21
percent increase in harvest levels of pine sawtimber. The Mills segment results
increased $4 million due primarily to an 18 percent increase in average finished
lumber sales price. Real Estate operating income increased $1.6 million due
primarily to increased commercial sales. The Agriculture segment results were
virtually unchanged from 1996. The cost of corporate functions increased $2.9
million.

     In the following table, the Company's net sales and results of operations
for the three years ended December 31, 1998 are presented by segment.  A review
of the information follows the table.

   Woodlands

     Net sales for the Company's Woodlands segment totaled $26.6 million in
1998, $22.6 million in 1997, and $16.4 million in 1996. Operating income for
this segment was $20.5 million in 1998, $18 million in 1997, and $12.5 million
in 1996.

     During 1998, net sales increased $4 million, 18 percent, to $26.6 million.
Pine sawtimber sales increased $3.2 million in 1998 which reflects the impact of
a $3.8 million increase attributable to higher sales volume, partially offset by
a $.7 million decrease due to lower average sales price.  The Company 

                                       18
<PAGE>
 
harvested 431,600 tons of pine sawtimber in 1998, an increase of 21 percent when
compared to 356,500 tons in 1997. The acquisition program, which began during
1996, has added approximately 58,600 acres of timberland and facilitated the
increased harvest level. Average sales price for Deltic's pine sawtimber was $51
per ton in 1998 versus $53 per ton in 1997, a decrease of four percent. Pine
pulpwood sales increased $.9 million due to increased harvest levels as the
Company thinned its maturing pine plantations. Sales of hardwood sawtimber
decreased $.3 million from $1.4 million primarily as the result of a decrease in
sales price. Other net sales for Woodlands increased slightly.

     Net sales in 1997 increased $6.2 million, 38 percent, to $22.6 million.
Sales of pine sawtimber increased $5.9 million over 1996 which reflects an
increase of $3.3 million attributable to higher sales volume coupled with a $2.6
million increase due to higher average sales price. The Company increased
harvest levels of pine sawtimber from 294,100 tons in 1996 to 356,500 tons in
1997, an increase of 21 percent. Deltic's average sales price for pine sawtimber
increased 20 percent, $53 per ton in 1997 compared to $44 per ton in 1996. The
increase in the price of pine sawtimber was the result of strong demand caused
by the high level of regional lumber production. Pine pulpwood and hardwood
sales increased $.5 million in 1997 due to higher volume and sales price. Other
net sales decreased $.2 million in 1997.

     Operating income of $20.5 million for 1998 was $2.5 million more than in
1997 due primarily to the increase in net sales discussed above.  The cost of
fee timber harvested increased $.8 million in 1998 due to an increase in timber
harvested and to higher depletion rates which are the result of acquiring
timberland.  An increase in cull timber release expense of $.3 million resulted
from the increase in the Company's timberland acreage.

     In 1997, operating income increased $5.5 million to $18 million as the
result of increased net sales, partially offset by an increase of $.3 million in
the cost of fee timber harvested and a $.3 million increase in cull timber
release expense.

   Mills

     Net sales for the Company's Mills segment were $65.8 million in 1998,
compared to $67.7 million in 1997 and $57.9 million in 1996.  An operating loss
of $2.8 million was recorded in 1998, while operating income was $7.4 million in
1997 and $3.4 million in 1996.

     In 1998, net sales decreased $1.9 million to $65.8 million.  Although
finished lumber sales volume increased nine percent to 162.2 million board feet
("MMBF") in 1998, a $53 per MBF decrease in average sales price to $343 per MBF
caused a decrease in net sales of $3.5 million.  Sawmill residual product sales
increased $1.1 million in 1998.  During 1998, the Company recorded a $.5 million
settlement of the business interruption claim filed as a result of a fire at the
Ola Mill during 1997.

     During 1997, net sales for this segment totaled $67.7 million, an increase
of $9.8 million. Finished lumber sales increased $11.2 million due to an $8.8
million increase which resulted from higher average sales price and a $2.4
million increase from greater sales volume.  In 1997, average sales price for
finished lumber was $396 per MBF, an 18 percent increase when compared to $335
per MBF in 1996.  The Company's sawmills experienced a four percent increase in
finished lumber sales volume, from 143.4 MMBF in 1996 to 149.4 MMBF in 1997.
Residual product sales declined by $1.4 million.

     A loss from operations of $2.8 million during 1998 compared to operating
income of $7.4 million in 1997.  The decrease was primarily the result of the
drop in net sales combined with a five percent increase in the cost of
production per MBF sold, partially offset by the previously mentioned business
interruption claim settled during 1998.  The increase in the cost of lumber
produced resulted from increases in log cost and depreciation expense.

                                       19
<PAGE>
 
     Operating income of $7.4 million for 1997 was $4 million more than for
1996, primarily attributable to a $61 per MBF increase in sales price to $396
per MBF coupled with a four percent increase in finished lumber sales volume,
partially offset by a 17 percent increase in the cost of logs used in the
Company's sawmills.

   Real Estate

     The Company's Real Estate operations generated net sales of $15.9 million
in 1998, $11.6 million in 1997, and $6.3 million in 1996. Operating income for
this segment totaled $5 million in 1998, $3.2 million in 1997, and $1.6 million
in 1996.

     Net sales in 1998 increased $4.3 million, 37 percent, from $11.6 million in
1997. Residential lot sales increased by 62 lots to 175, with the average sales
price up six percent over 1997, from $52,400 per lot to $55,600. During 1998,
325 lots were developed and offered for sale in Chenal Valley in west Little
Rock, Arkansas, and in Red Oak Ridge near Hot Springs, Arkansas. Sales of
approximately 96 acres of undeveloped real estate acreage for $.6 million in
1998 compares to the sale of 9.5 acres for $.2 million during 1997. Commercial
sales revenue decreased $1.1 million due to the sale of approximately 26 acres
at an average price per acre of $90,900 in 1997, which compares to sales of
about eight acres for $158,000 per acre in 1998. Net sales from the Company's
Chenal Country Club operation were $3.3 million for 1998 versus $2.3 million for
the eight months of 1997 following the acquisition of the Club by Deltic.
Operating income for the Real Estate segment increased $1.8 million to $5
million due primarily to a $1.9 million increase in the margin realized on sales
of real estate in 1998.

     In 1997, Real Estate operations generated net sales of $11.6 million, $5.3
million more than in 1996. Sales of residential and commercial property
increased $2.6 million. The sale of residential lots increased 19 percent, from
95 lots in 1996 to 113 lots in 1997, with a slight decrease in average sales
price from $55,400 to $52,400. During 1997, 149 lots were developed and offered
for sale in Bayonne Place; DuQuesne Place, Chenal Valley's newest neighborhood
which was priced to enter a new segment of the market; and Chenal Downs, a 400-
acre equestrian development located outside of Chenal Valley. Two commercial
sites were sold in 1997 for multi-family developments and totaled 26.4 acres at
an average price per acre of $90,900, which compares to a 2.1-acre tract for
$199,500 per acre in 1996. On May 1, 1997, the Company acquired Chenal Country
Club, Inc., a newly-formed entity that operates the Club amenity around which
Chenal Valley is centered. The acquisition was accomplished by exchanging a $5.6
million interest-bearing receivable from the club membership, which was
previously held by Deltic, for an investment in the newly-formed subsidiary.
Chenal Country Club, Inc.'s financial results included net sales of $2.3 million
and cost of sales totaling $2.1 million. The cost of the clubhouse and golf
course facilities acquired is being accounted for as an additional amenity for
the Chenal Valley development. Real Estate operating income of $3.2 million for
1997 increased $1.6 million when compared to 1996, due primarily to the same
factors impacting net sales.

   Agriculture

     Deltic's Agriculture segment recorded net sales of $6.5 million during
1998, compared to $9.5 million in 1997 and $10.6 million in 1996. Operating
income totaled $.8 million in 1998, and $2.8 million in both 1997 and 1996.

     During 1998, net sales of $6.5 million decreased $3 million from 1997. The
decrease was the result of lower commodity prices and soybean yields, combined
with the prior year benefiting from the sale of products which were grown during
1996. Operating income of $.8 million was down $2 million from 1997 and was
negatively impacted by an increase in harvesting costs for corn due to an
outbreak of Aflatoxin, a toxin-producing fungus, in addition to lower net sales
discussed earlier. In 1998, soybean 

                                       20
<PAGE>
 
yields per acre decreased nine percent and the sales price was 19 percent lower
than in 1997. Although corn yields per acre increased four percent, sales prices
were down ten percent in 1998.

     Agriculture operations contributed $9.5 million in net sales during 1997,
down $1.1 million from 1996. This decrease was primarily due to a 43 percent
reduction in cotton production volume in 1997 compared to 1996, which resulted
from diverting about 2,000 acres from cotton production to other crops. Although
revenue decreased in 1997, a corresponding reduction in crop costs was achieved.
Operating income of $2.8 million in 1997 was essentially unchanged from 1996. In
1997, crop yields per acre for cotton and wheat increased 19 percent and 25
percent, respectively, while per acre yields for soybeans and corn decreased
nine percent and four percent.

   Corporate

     Corporate operating expense was $5 million in 1998, $5.2 million in 1997,
and $2.3 million in 1996.  During 1998, the Company's general and administrative
expenses decreased $.4 million.  These expenses increased $2.7 million in 1997
due to higher expenses incurred as an independent, public company.  The cost of
certain administrative and financial services provided by Murphy Oil, Deltic's
parent prior to spin-off, was included in general and administrative expenses
and totaled $.5 million in 1997 and $1.3 million in 1996.  These services were
provided by Murphy Oil through June 30, 1997.

   Equity in Del-Tin Fiber

     In 1998, the Company recorded equity in the loss of Del-Tin Fiber totaling
$4.6 million, which included plant start-up costs incurred to-date and operating
losses reported since initial production began in late April 1998.

   Interest Income/Expense

     Interest income during 1998 was $1.1 million, compared to $.7 million in
1997 and $3.1 million in 1996.  The $2.4 million decrease in 1997 was due
primarily to settlement of an interest-bearing receivable from Murphy Oil.
Deltic's interest income from this receivable was $2.4 million in 1996.  In
1998, interest expense was $1.4 million, versus $.4 million in 1997 and $.3
million in 1996.  The increase of $1 million during 1998 was due primarily to
increased borrowings required for Deltic's land acquisition program.

   Other Income

     Other income was $.4 million in 1998, $1.4 million in 1997, and $1.2
million in 1996.  During 1997, the Company realized a $1.2 million gain on
settlement of a physical damage insurance claim which was the result of a fire
that destroyed the Ola Mill lumber planer.  A $.7 million gain on the sale of
approximately 3,200 acres of Arkansas farmland was recorded during 1996.

   Income Tax Expense

     The Company's income tax expense was $5.3 million for 1998, $10.7 million
for 1997, and $8.8 million for 1996. The effective income tax rate was 38
percent, 39 percent, and 40 percent in 1998, 1997, and 1996, respectively. The
Company's income tax expense declined $5.4 million, from $10.7 million in 1997,
primarily due to lower pretax earnings. The increase in income tax expense of
$1.9 million in 1997 was due to similar increases in pretax earnings.

LIQUIDITY AND CAPITAL RESOURCES

   Cash Flows and Capital Expenditures

     Net cash provided by operating activities was $27 million in 1998, compared
to $23.9 million in 1997 and $21.7 million in 1996. Changes in operating working
capital, other than cash and cash equivalents, required cash of $.2 million in
1998 and $.5 million in 1997, but provided cash of $.6 million in 1996. The
Company's accompanying Consolidated Statements of Cash Flows identify other
differences between net income and cash provided by operating activities for
each of those years.

     Capital expenditures required cash of $80.1 million in 1998, $35.7 million
in 1997, and $14.1 million in 1996. Other owner-financed capital expenditures,
not requiring cash, included timberland acquisitions of $.4 million in 1998 and
$.1 million in 1997. Total capital expenditures are presented by segment in the
following table for the years ended December 31, 1998, 1997, and 1996.

     Woodlands capital expenditures included timberland acquisitions of
approximately 30,400 acres at a cost of $59.1 million in 1998, approximately
25,100 acres at a cost of $15.9 million in 1997, and approximately 3,100 acres
at a cost of $2.5 million in 1996. Reforestation site preparation and planting
required expenditures of $.4 million in 1998, $.2 million in 1997, and $.1
million in 1996.

     During 1998, $3.5 million was expended for the Ola Mill's planer upgrade.
The installation of a new boiler system and an additional kiln, which will
increase drying capacity by 30 million board feet annually, required
expenditures of $1.6 million in 1998 and $3 million in 1997. A small log
processing deck, which has enabled the mill to extract small diameter logs from
pulpwood to facilitate log supply and reduce log cost, required expenditures of
$.4 million in 1998 and $1.4 million in 1997. In 1996, $.7 million was expended
to expand the lumber sorting system. At the Waldo Mill, $.5 million was expended
in 1998 and $1.6 million in 1997 to install a new secondary manufacturing
operation, which has expanded the Mill's product mix to include products such as
finger-jointed studs. The Waldo Mill's planer upgrade required capital
expenditures of $4.1 million in 1997 and $1.4 million in 1996.

     Capital expenditures for Real Estate operations related to cost of lot
development were $5.1 million in 1998, $2.1 million in 1997, and $.4 million in
1996. Commercial development expenditures included $.4 million in 1998 for site
work for outparcel sites adjacent to the Company's 35,000-square-foot retail
center for which construction is planned to be completed during 1999, $.6
million in 1997 for site work for the retail center, and $4.5 million in 1996
for construction of a 50,000-square-foot office building which the Company
offers for lease. In 1998, infrastructure construction totaled $.8 million,
compared to $1.3 million in 1997 and $.4 million in 1996. An expansion of the
clubhouse at Chenal Country Club required capital expenditures of $3 million in
1998 and $.6 million in 1997. Other expenditures were primarily for various
amenity improvements.

                                       22
<PAGE>
 
     Agriculture expenditures included $.4 million in both 1998 and 1997 for
purchase of harvesting combines. In 1997, two continuous-flow drying systems
were installed for $.4 million. Other capital requirements were mainly for
replacement of various machinery and equipment.

     Corporate operations had capital expenditures for purchases of additional
investment in a consolidated entity of $.4 million in 1998 and $.9 million in
1996. Expenditures for 1997 of $.5 million were primarily for the purchase of
office furniture and computer equipment, including software, required when the
Company's offices were relocated after being spun off from Murphy Oil.

     At December 31, 1998, the Company had commitments of $12.3 million for
capital projects in progress, including $3.7 million for improvements at the Ola
Mill and $7.9 million related to residential lot and commercial development,
infrastructure construction, and amenity improvements at the Company's real
estate developments.  The Ola Mill's commitments consisted of $1.9 million for
an edger and edger optimizer, $1.3 million for completion of a planer upgrade,
and $.5 million for sawmill building improvements.

     The net change in purchased stumpage inventory required cash of $2.7
million in 1998 and $2.9 million in 1997, and provided cash of $2.8 million in
1996. Proceeds from the sales of assets provided $.4 million in 1998; $1.4
million in 1997, due primarily to the involuntary conversion of the Ola Mill's
planer which was destroyed by fire; and $2.9 million in 1996, primarily from the
sale of approximately 3,200 acres of Arkansas farmland. In 1996, as part of the
spin-off of the Company by Murphy Oil, the Company received a $17.2 million cash
payment from Murphy Oil in partial settlement of its receivable from Murphy Oil.
Prior to the spin-off, the Company remitted to Murphy Oil cash funds generated
in excess of its daily requirements. As a result, the receivable had increased
by $7.9 million in 1996. Also, in connection with the spin-off, the Company
recorded an $18.8 million noncash dividend to Murphy Oil which reduced the
outstanding balance of the receivable. (Refer to Note 2 to the consolidated
financial statements.) The Company advanced to Del-Tin Fiber $9.6 million, $1
million, and $6.8 million in 1998, 1997, and 1996, respectively. In December
1998, Del-Tin Fiber repaid $5.6 million of previous advances when project
financing for the facility was obtained. In conjunction with this repayment, the
remaining outstanding advances receivable amount was deemed to be a capital
contribution to the joint venture.

     During 1998, the Company borrowed $48 million under its revolving credit
facility, primarily to finance timberland acquisitions. (Refer to Note 9 to the
consolidated financial statements.) Upon issuance of $40 million of privately-
placed, fixed-interest rate, long-term senior notes with a financial institution
on December 18, 1998, the Company used the proceeds, net of $1.3 million in
prepaid interest and debt issuance costs, to make repayment against its
revolving facility. In addition, $3 million of the repayment received from Del-
Tin Fiber was applied to the revolving facility commitment. During 1997, the
Company issued 600,000 shares of Redeemable Preferred Stock, proceeds of which
were $29.6 million, net of issuance costs. (Refer to Note 10 to the consolidated
financial statements.) In addition, borrowings under Deltic's revolving facility
in 1997 provided $3 million, which were also repaid during the year. Cash
required to repay long-term debt arising from installment payments on notes used
to finance a portion of the Company's timber requirements amounted to $1.8
million in both 1998 and 1997, and $.4 million in 1996. The Company paid
dividends on Common Stock of $3.2 million in both 1998 and 1997. During 1998,
cash required to pay Preferred Stock dividends totaled $2.3 million.

   Financial Condition

     Year-end working capital totaled $16.5 million in 1998 and $38 million in
1997. Cash and cash equivalents at the end of 1998 were $8.2 million, compared
to $31 million at the end of 1997. The reduction for 1998 was primarily
attributable to the amount by which capital expenditures for the year exceeded
net borrowings during the year. During 1998, indebtedness of the Company
increased 

                                       23
<PAGE>
 
$43.5 million. The Company's working capital ratio at December 31, 1998, was 3.5
to 1, compared to 5.9 to 1 at the end of 1997.

   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 a significant timberland acquisition
program, which has facilitated an increase in harvest levels, as it is expanding
lumber production and entering the engineered wood products market through its
interest in Del-Tin Fiber.

     To facilitate these growth plans, the Company has an agreement with a group
of banks which provides a revolving credit facility totaling $100 million.  The
agreement will expire on December 31, 2001.  As of December 31, 1998, $95
million was available under this facility.  Current financing arrangements are
set forth in Note 9 to the consolidated financial statements.  Due to the amount
available under its credit facility, combined with successfully obtaining $40
million of privately-placed debt at terms acceptable to the Company, Deltic does
not currently anticipate filing the Common Stock shelf registration with the
Securities and Exchange Commission which was mentioned in the Company's 1997
Form 10-K.

     On January 14, 1999, the Company's Board of Directors authorized a stock
repurchase program through which the Company's management has approval to
purchase up to $10 million of Common Stock, initially.  Under the program, the
Company can purchase shares through the open market and privately negotiated
transactions at prices deemed appropriate by management, utilizing cash provided
by operations and/or from its credit facility.

     Deltic's management believes that the remaining amount available under its
credit facility will be sufficient to meet its expected cash needs and planned
expenditures, including those of the Company's continued timberland acquisition
and authorized Common Stock repurchase programs, for the foreseeable future.


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, 1998.  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.

   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
enter into financial instruments to manage and reduce the impact of changes in
interest rates.  The counterparties in these financial instruments are normally
major financial institutions.  Deltic held various financial instruments at
December 31, 1998 and 1997, consisting of financial assets and liabilities
reported in the Company's 

                                       24
<PAGE>
 
Consolidated Balance Sheets and off-balance sheet exposures resulting from
letters of credit issued by Deltic, primarily in connection with its purchased
stumpage procurement and real estate operations. (For additional information
regarding these financial instruments, refer to Note 13 to the consolidated
financial statements.)

     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; Redeemable Preferred
Stock; and letters of credit at December 31, 1998, were $46.2 million, $31.2
million, and $3.5 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 $4 million and
Redeemable Preferred Stock of $1.2 million, while the fair value of the
Company's letters of credit would be unchanged.  Initial fair values were
determined using the current rates at which the Company could enter into
comparable financial instruments with similar remaining maturities.  The
estimated earnings and cash flows impact for 1999 resulting from a one
percentage-point increase in interest rates would be approximately $35 thousand,
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.

   Impact of Accounting Pronouncements

     In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards ("SFAS") 133, Accounting for Derivative
Instruments and Hedging Activities.  This standard establishes accounting and
reporting standards for derivative instruments, including certain derivative
instruments embedded in other contracts, and for hedging activities.  SFAS 133
is effective for all fiscal quarters for fiscal years beginning after June 15,
1999 and will not require retroactive restatement of prior period financial
statements.  This statement requires the recognition of all derivative
instruments as either assets or liabilities, measured at fair value, in the
statement of financial position. Generally, increases or decreases in the fair
value of derivative instruments will be recognized as gains or losses in
earnings in the period of change.  If certain conditions are met, where the
derivative instrument has been designated as a fair value hedge, the hedged item
may also be marked to market through earnings, thus creating an offset.  If the
derivative is designated and qualifies as a cash flow hedge, the changes in fair
value of the derivative instrument may be recorded in comprehensive income, 

                                       25
<PAGE>
 
as defined by SFAS 130, Reporting Comprehensive Income. The impact of SFAS 133
on the Company's financial statements when adopted, if any, will depend on a
variety of factors, including future interpretive guidance from the FASB, the
level of utilization of derivative instruments, the types of hedging instruments
used, and the effectiveness of any such instruments. However, the Company's
management does not believe the effect of adopting SFAS 133 will be material to
its financial position or results of operations, based on the Company's current
level of derivative and hedging activities.

   Year 2000 Issue

     The Year 2000 issue is the known inability of a significant percentage of
the world's computers, application software, and embedded semiconductor chips to
cope with the change of the year from 1999 to 2000. As a result, some systems
could fail to operate or produce incorrect results.

     The Year 2000 problem, if not corrected, would affect computers, software,
and other equipment used by the Company, as well as those used by its suppliers,
customers, banks, etc.  Accordingly, Deltic has assessed the potential impact
of, and the costs of remediating, the Year 2000 problem for its internal systems
and operational facilities' systems and equipment.

     The Company's business is substantially dependent upon the operation of
computer systems, and as such, Deltic has established a Year 2000 Committee
which is made up of managers from its corporate and operational areas.  The
Committee was created pursuant to the direction of the Company's Board of
Directors and has the involvement of executive management, with top priority
given to its objectives.

     The Company has essentially completed the process of identifying the
computers, application software, and related equipment that must be modified,
upgraded, or replaced to minimize the possibility of a material disruption of
its business. The Company has commenced the process of modifying or upgrading
systems which have been assessed as affected by the Year 2000 problem. For
critical internal computerized systems, the Company expects to complete this
process by the end of the first quarter of 1999. For remaining major systems and
equipment, including those at operational facilities, the Company anticipates
the completion of any modifications or upgrades required no later than the third
quarter of 1999. To-date, the Company has not incurred significant costs for
these modifications since most have been provided by the supplier at no or
minimal cost to Deltic. Therefore, the cost related to the Year 2000 Issue
incurred by the Company for its internal systems and facilities is not expected
to be material.

     In addition to computers and related equipment, the Year 2000 Committee has
completed the assessment of the potential impact of the Year 2000 problem for
its equipment such as fax machines, copiers, telephone and security systems, and
other common devices potentially impacted by the Year 2000 problem. As of
December 31, 1998, all of this equipment has been determined to be Year 2000
compliant.

     The Company has initiated communications with third-party suppliers of the
major computers, software, and other equipment used, operated, or maintained by
the Company, including those at its operational facilities, to identify and, to
the extent possible, resolve issues involving the Year 2000 problem.  Since the
Company has limited or no control over the actions of these suppliers, there can
be no assurance that these suppliers will resolve all Year 2000 problems,
whether currently known or not, or that the Company will be able to obtain
replacement suppliers, before the occurrence of a material disruption to the
business of the Company.

                                       26
<PAGE>
 
     In addition, the Company has issued written communication to all of its
suppliers and significant customers in order to attempt to obtain the status of
their Year 2000 compliance. To-date, the majority of these suppliers and
customers have responded to such communications and have indicated that they
have either already achieved Year 2000 compliance or expect to be able to do so
prior to December 31, 1999. However, the Company can give no assurance that its
suppliers or customers will not be materially impacted by the Year 2000 issue.
In addition, the Company can give no assurance that failure by its suppliers and
customers to achieve Year 2000 compliance will not have a significant impact on
the Company's business. However, Deltic intends to continue follow-up
communications with critical suppliers and customers.

     At this time, the Company is currently developing a contingency plan which
would be implemented in the event that efforts to identify and correct Year 2000
problems are not effective.  As the Company's assessment of its Year 2000
compliance is nearer to completion, the Company's Year 2000 Committee currently
plans to finalize contingency plans for any systems or facilities for which Year
2000 compliance is not reasonably certain.

     The discussion of the Company's efforts, and management's expectations,
relating to Year 2000 compliance are "forward-looking statements" within the
meaning of the federal securities laws.  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.  The
Company's ability to achieve Year 2000 compliance and the level of incremental
costs associated therewith, could be adversely impacted by, among other things,
the availability and cost of programming and testing resources, suppliers'
ability to modify proprietary software, and unanticipated problems identified in
the ongoing compliance review.

   Environmental Matters

     Deltic is committed to protecting the environment and has certain
obligations based on federal, state, and local laws for the protection of the
environment. Costs of compliance through 1998 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.


OUTLOOK

     Pine sawtimber harvested from the Company's fee lands is projected to
increase annually through 2000, depending on the Company's ability to increase
timber inventory through growth and timberland acquisitions.  Lumber production
is also projected to increase over this period, as the Company continues to
increase the capacity of its manufacturing facilities.  Based on continued
growth in west Little Rock, Arkansas, the Company expects the number of
residential lots and commercial acres sold to increase, barring declines in
economic growth or housing starts in central Arkansas.  Agriculture operations
intend to plant soybeans and corn in 1999, with results subject to a number of
factors including weather conditions, insect infestation, crop disease, and
price fluctuations.  The Company expects medium density fiberboard production
and sales at Del-Tin Fiber to increase significantly in 1999, as capacity
utilization increases following the plant's start-up in April 1998.

     The Company's capital expenditure budget for the year of 1999 was prepared
during the fall of 1998 and provides for expenditures of $38.6 million. The
Woodlands capital budget includes $12.2 million for timberland acquisitions,
which will be dependent on the availability of acreage at prices which meet the
Company's criterion for timber stocking, growth potential, site index, and

expected to improve recovery and increase mill output by five million board feet
annually. Depending on market conditions, expenditures for residential lot
developments in the amount of $3.2 million are projected to add over 130 lots to
available inventory. Commercial real estate development and infrastructure
construction is estimated at $5.1 million and includes construction of a retail
center in "The Village at Rahling Road", located in Chenal Valley. Golf course
and clubhouse expansion projects are estimated to require capital expenditures
of $2.8 million. Replacements of machinery and equipment for the Agriculture
segment are anticipated to require $.5 million. 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 under
credit facilities, or general economic conditions.

                               AND SUBSIDIARIES
                  Notes to Consolidated Financial Statements
                               December 31, 1998


NOTE 1 - SIGNIFICANT ACCOUNTING POLICIES

    Principles of Consolidation -- The consolidated financial statements 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 financial statements of the 
       Company in conformity with generally accepted accounting principles, 
       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, 1998 and 1997, the balance in the allowance
       account was $189,000 and $95,000, respectively.

    Inventories  --  Inventories of logs, lumber, agricultural products, 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.

    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, less amounts charged to cost 
       of sales. These 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 three 
       development areas, Chenal Valley, Chenal Downs, and Red Oak Ridge, are 
       allocated to neighborhoods over the entire respective development area.

    Investment in Del-Tin Fiber -- Investment in Del-Tin Fiber L.L.C. ("Del-Tin
       Fiber"), the 50 percent- owned limited liability company, is carried at
       cost and is being adjusted for the Company's proportionate share of its
       undistributed earnings or losses.

    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 the cost of roads constructed and other land improvements, 
       are depreciated by 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.

                               AND SUBSIDIARIES
                  Notes to Consolidated Financial Statements
                               December 31, 1998


    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 by using
       the straight-line method. Property, plant, and equipment assets are
       evaluated for possible impairment on a specific asset basis or in groups
       of similar assets, as applicable. Expenditures that substantially improve
       and/or increase the useful life of facilities and 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.

    Revenue Recognition  --  Revenue from the sale of lumber, wood by-products,
       and agricultural commodities is generally recorded at the time of
       shipment. Revenue from the sale of timber-cutting rights to third parties
       is recorded when legal title passes to the purchaser. Revenue from
       intersegment timber sales is recorded when the timber is harvested; such
       intersegment sales, which are made at market prices, are eliminated in
       the consolidated financial statements. Revenue from real estate sales is
       recorded when the sale is closed and legal title is transferred.

    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 basis of existing assets and
       liabilities, and is measured using the enacted tax rates that are assumed
       will be in effect when the differences reverse.

       The Company was included in the consolidated federal tax return of Murphy
       Oil Corporation ("Murphy Oil"), Deltic's parent prior to its spin-off,
       for the 1996 period for which income statements are presented; however,
       for financial accounting purposes, federal income tax has been computed
       and recorded as if the Company filed a separate federal income tax
       return. Deltic filed its initial separate federal income tax return for
       the year of 1997.

    Pensions and Other Postretirement Benefits  --  Effective December 31, 1998,
       the Company adopted Statement of Financial Accounting Standards ("SFAS")
       132, Employers' Disclosures about Pensions and Other Postretirement
       Benefits. The provisions of SFAS 132 revise employers' disclosures about
       pension and other postretirement benefit plans. It does not change the
       measurement or recognition of these plans. It standardizes the disclosure
       requirements for pensions and other postretirement benefits to the extent
       practicable. (For details of required disclosures, see Note 15 - Employee
       and Retiree Benefits.)

    Stock-Based Compensation  --  The Company applies the accounting measurement
       provisions of Accounting Principles Board Opinion ("APB") 25 to account
       for stock-based compensation. Cost of options granted are accrued over
       applicable vesting periods and adjusted for subsequent changes in the
       market value per share of the Company's Common Stock.

    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

       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
       were calculated under the provisions of SFAS 128, Earnings per Share.
       Basic earnings per share is computed based on earnings available to
       Common shareholders (net income less accrued preferred dividends) 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 option plan. (For a reconciliation of amounts used in
       per share computations, see Note 18 - Earnings per Share.)

    Reclassifications -- Certain prior year amounts have been reclassified to
       conform with the 1998 presentation format.

NOTE 2 - SPIN-OFF FROM MURPHY OIL CORPORATION

    On December 31, 1996, Deltic Timber Corporation became an independent,
    public company when Murphy Oil, the Company's former parent, surrendered 100
    percent of the outstanding shares of Deltic Common Stock, which were
    distributed to Murphy Oil's shareholders as a dividend. Through December 10,
    1996, the Company operated under Murphy Oil's consolidated cash management
    policy. Under this policy, Deltic remitted cash funds generated in excess of
    its daily operating and capital requirements to Murphy Oil. Such remitted
    funds gave rise to an interest-bearing receivable that was due on demand.
    Settlement of this receivable was accomplished by recording noncash
    dividends from Deltic to Murphy Oil, in the amount of $18,813,000, and a
    cash repayment by Murphy Oil to the Company of $17,200,000, leaving a net
    receivable of $1,858,000 at December 31, 1996, with no amount due at
    December 31, 1998 and 1997. Deltic realized interest income from Murphy Oil,
    related to this receivable, of $2,374,000 in 1996.

    Murphy Oil personnel historically performed certain administrative and
    financial services on behalf of the Company. These services included, among
    others, cash management and consultation related to certain personnel,
    employee benefit, and income tax matters. During 1997, Murphy Oil continued
    to provide, or caused to be provided, certain specified services for a
    transitional period ending June 30, 1997. Deltic personnel have assumed
    responsibility for all functions previously provided by Murphy Oil. The
    Company recorded charges of $427,000 in 1997 and $1,250,000 in 1996 for
    these services. Of the total amount expensed for services during 1996,
    $630,000 ($384,000 net of tax) was a capital contribution (recorded as an
    adjustment to Capital in Excess of Par Value) by Murphy Oil since payment
    was not required. The cost for each year was included in General and
    Administrative Expenses in the Consolidated Statements of Income for the
    respective years.

    In addition, during 1996, capital contributions by Murphy Oil were recorded
    as a result of the transfer of $1,177,000 for prepaid retirement cost and
    $1,419,000 for accrued postretirement obligations from Murphy Oil to Deltic
    for employees and retirees transferred between the two companies. These
    capital contributions ($1,687,000 net of income taxes) are recorded as
    adjustments to Capital in Excess of Par Value.

NOTE 4 - ACQUISITION OF CHENAL COUNTRY CLUB, INC.

    During 1997, the Company acquired the net assets of Chenal Country Club, the
    entity that had operated the club amenity around which Deltic's Chenal
    Valley real estate development is centered. The cost of the clubhouse and
    golf course facilities acquired is being accounted for as an additional
    amenity for the Chenal Valley development. The acquisition was accomplished
    by exchanging an interest-bearing receivable from the club membership, which
    had been previously held by Deltic, in the amount of $5,600,000, for the
    clubhouse and golf course facilities and an investment in 100 percent of the
    stock of Chenal Country Club, Inc., a wholly-owned subsidiary formed, at the
    time of the acquisition, to continue the daily operating activities of the
    club. The operating assets of the former Chenal Country Club, excluding the
    clubhouse and golf course facilities, were transferred to this subsidiary.

    Deltic had previously constructed the clubhouse and golf course and
    purchased the original operational assets of the club amenity and sold them
    to the club membership in exchange for the original interest-bearing
    receivable. Chenal Country Club, Inc. continued to operate the club for the
    remainder of 1997 and the entire year of 1998. The results of operations of
    Chenal Country Club, Inc., since the date of the acquisition, are included
    in the accompanying financial statements. However, upon the exchange of the
    interest-bearing receivable for the acquisition, Deltic ceased to earn
    interest income related to the receivable as of April 30, 1997.

    The acquisition was recorded using the purchase method of accounting for
    business combinations. Operating income of Chenal Country Club, Inc.
    included in the amounts reported in the Consolidated Statement of Income for
    1997 was $104,000, and was comprised of net sales of $2,277,000, cost of
    sales of $2,065,000, and depreciation expense of $108,000. Due to the
    approximately break-even level for operating income of Chenal Country Club,
    Inc., Deltic's financial statements would not be materially impacted had the
    operations of this new subsidiary been included for 1996 and the entire year
    of 1997. Interest income on the receivable from the club membership prior to
    the acquisition was $173,000 in 1997 and $542,000 in 1996.

NOTE 5 - INVESTMENT IN DEL-TIN FIBER

    Deltic owns 50 percent of the membership interest of Del-Tin Fiber, which
    completed construction of a medium density fiberboard ("MDF") plant near El
    Dorado, Arkansas, in April 1998. The cost to construct the plant was
    approximately $100,000,000. Each of Del-Tin Fiber's two owners recorded an
    initial investment of approximately $12,000,000, with the remainder financed
    by Del-Tin Fiber with a combination of borrowings and issuance of
    interest-bearing bonds. Separate project financing for the plant was
    finalized during 1998.

                               December 31, 1998


    Each owner has agreed to a contingent equity contribution agreement with
    Del-Tin Fiber and the group of banks from whom the project financing was
    obtained. Under this agreement, each owner has agreed to fund any deficiency
    in contributions to either Del-Tin Fiber's bond sinking fund or debt service
    reserve, if any, up to $17,500,000. Del-Tin Fiber's project financing
    agreement does not require sinking fund or debt reserve contributions until
    2000. In addition, each owner has committed to a production support
    agreement, under which each owner has 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 if the plant is unable to
    successfully complete a minimum production test, planned for the summer of
    1999. Both owners of Del-Tin Fiber have also pledged their respective
    membership interest in the joint venture as collateral under the project
    financing agreement.

    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 1998, Deltic sold approximately $2,126,000
    of these lumber manufacturing by-products to Del-Tin Fiber. The plant
    commenced production operations on April 29, 1998.

    The results of operations for years ended December 31 and financial position
    at December 31 for Del-Tin Fiber consisted of the following:

                               December 31, 1998


    At December 31, 1998 and 1997, the Company's share of the underlying net
    assets of Del-Tin Fiber exceeded its investment by $167,000 and $577,000,
    respectively. The excess relates primarily to interest received by the
    Company from Del-Tin Fiber prior to plant start-up, which was capitalized by
    Deltic as a reduction of its investment, and is being amortized into income
    using the straight-line method over a 60-month period.

    The Company accounts for its investment in Del-Tin Fiber under the equity
    method. Accordingly, the investment in Del-Tin Fiber is carried at cost,
    adjusted for the Company's proportionate share of earnings or losses
    recorded on a one-month lag basis.

</TABLE> 

    Cost of fee timber harvested amounted to $1,800,000 in 1998, $1,404,000 in
    1997, and $1,060,000 in 1996. Depreciation of logging facilities was
    $73,000, $84,000, and $94,000 for the years 1998, 1997, and 1996,
    respectively.

    The Company obtains a portion of its sawmill log requirements by acquiring
    purchased stumpage inventory through cutting contracts with various private
    and governmental landowners. These contracts have terms ranging from a few
    months to several years. At December 31, 1998, the Company's total
    commitment under such contracts amounted to approximately $8,196,000. Based
    on lumber prices at December 31, 1998, management estimated the fair value
    of stumpage under such contracts to be approximately $6,262,000. Depending
    on the market value of this stumpage at time of harvest, the Company's
    sawmills may experience favorable or unfavorable log supply costs. By
    February 5, 1999, the lumber market had improved to the point that the
    estimated fair value of timber under these contracts had increased to
    approximately $7,250,000.

    $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 additional interest expense over the term of the underlying
    debt, resulting in an effective interest rate for these notes of
    approximately 6.9 percent.

    The scheduled maturities of long-term debt for the next five years are
    $990,000 in 1999, $198,000 in 2000, and $5,000,000 in 2001. (For additional
    information regarding financial instruments, see Note 13 - Fair Value of
    Financial Instruments.)

NOTE 9 - CREDIT FACILITIES

    In 1996, Deltic entered into an agreement with NationsBank, N.A. and other
    domestic banks which provides an unsecured, committed revolving credit
    facility totaling $100,000,000. The agreement will expire on December 31,
    2001. As of December 31, 1998, $95,000,000 of committed credit was available
    in excess of all borrowings outstanding under or supported by the facility.
    Borrowings under the agreement bear interest based upon prime or other
    various cost of funds options. Fees associated with this revolving credit
    facility include a commitment fee of .15 to .35 percent per annum on the
    unused portion of the commitment balance. The revolving credit agreement
    contains certain restrictive financial covenants, including a maximum funded
    debt/capitalization ratio of .5 to 1, which is to be maintained throughout
    the term of the credit agreement.

    The Company may also borrow up to $5,000,000 under a short-term credit
    facility with First National Bank of El Dorado. The agreement expires May 8,
    1999, with renewal annually. The amount available to the Company under this
    facility is reduced by any outstanding letters of credit issued by Deltic.
    As of December 31, 1998, letters of credit amounting to $950,000 were
    committed, resulting in $4,050,000 available to the Company. Borrowings bear
    interest based upon the New York Prime and the facility carries a commitment
    fee of .1 percent per annum on the unused amount of the facility.

    In addition, Deltic entered into an agreement with First Commercial Bank of
    Little Rock which provides a $2,555,000 credit facility used primarily to
    support letters of credit issued in connection with the Company's purchased
    stumpage procurement and real estate development operations. The agreement,
    which is renewable annually, carries no facility fees and borrowings bear
    interest based upon prime. Amounts available to Deltic under the facility
    are reduced by any outstanding letters of credit, which amounted to the
    entire balance of the facility at December 31, 1998, leaving none available
    to the Company. (For additional information regarding these financial
    instruments, see Note 13 - Fair Value of Financial Instruments.)

NOTE 10 - REDEEMABLE PREFERRED STOCK

    During 1997, the Company issued 600,000 shares of its authorized Preferred
    Stock having a par value of $.01 per share. Redemption of these shares,
    designated as Cumulative Mandatory Redeemable Preferred Stock, 7.54% Series
    ("Redeemable Preferred Stock"), by the Company is mandatory on December 31,
    2002 ("Mandatory Redemption Date"). These Redeemable Preferred shares have
    no voting rights, except if at any time, cumulative dividends payable for
    these shares become in arrears for an amount equal to dividends payable for
    six quarterly dividends or the shares are not redeemed in full on the
    Mandatory Redemption Date. If either occurs, the holders of the Redeemable
    Preferred shares shall have the right to elect a director to the Board of
    Directors, which would be in addition to the current number of directors.
    This right shall continue until such time that all cumulative unpaid
    dividends have been paid or the Redeemable Preferred shares are redeemed.

</TABLE> 

    Net noncurrent deferred tax liabilities of $1,701,000 at December 31, 1998,
    and $440,000 at December 31, 1997, are included in the Consolidated Balance
    Sheets in Deferred Credits and Other Liabilities for the respective years.
    In addition, current deferred tax assets of $382,000 at December 31, 1998,
    and $378,000 at December 31, 1997, are included in the Consolidated Balance
    Sheets in Prepaid Expenses and Other Current Assets for the respective
    years.

    In management's judgment, the Company's deferred tax assets at December 31,
    1998, will more likely than not be realized as reductions of future taxable
    income or by utilizing available tax planning strategies. There were no
    valuation allowances for deferred tax assets at the end of each year in the
    three years ended December 31, 1998.

NOTE 12- 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 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 13 - FAIR VALUE OF FINANCIAL INSTRUMENTS

    The following table presents the carrying amounts and estimated fair values
    of financial instruments held by the Company at December 31, 1998 and 1997.
    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 table excludes cash and cash equivalents, trade accounts
    receivable, notes payable, trade accounts payable, and accrued liabilities,
    all of which had fair values approximating carrying values.

    Long-term debt, including current maturities -- The fair value is estimated
       based on current rates at which the Company could borrow funds with
       similar remaining maturities.

    Redeemable preferred stock -- The fair value is based on the redemption
       amount for the stock, discounted using the Company's estimated borrowing
       rate for debt instruments with similar remaining maturities.

    Letters of credit -- The fair value is based on the estimated cost to settle
       these obligations.

NOTE 14 - 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, primarily finished lumber. 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
    customer accounted for a significant amount of the Company's sales of timber
    or wood products. At December 31, 1998, one timber sale customer's
    receivable accounted for approximately 12 percent of the Company's
    consolidated trade accounts receivable amount.

    Within the Agriculture segment, the Company is exposed to a minimal level of
    credit risk in that the majority of farm crops grown are delivered to a
    small number of grain elevators and these elevators are limited to the
    geographic area in which the Company's agriculture operations are located.
    However, receipt of payment from these elevators usually occurs at the time
    of delivery. At December 31, 1998, the Company had no significant accounts
    receivable outstanding in this area.

    Through December 31, 1996, Deltic employees were participants in the
    employee and retiree benefit plans of Murphy Oil. Amounts presented for 1996
    reflect the Company's portion of these respective plans. Effective January
    1, 1997, separate plans were implemented for active Deltic employees. Any
    vesting in the plans of Murphy Oil was retained by employees for Deltic's
    plans; and plans implemented by the Company were similar, in all aspects, to
    those of Murphy Oil.

    Retirement Plan -- The Company has a noncontributory, defined benefit
       retirement plan that covers substantially all employees. Benefits are
       based on years of service, including those with Murphy Oil, and final
       career-average-pay formulas as defined by the plan.

    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, based on length of participation in the plan. Company
       contributions to this plan were $371,000 in 1998, $279,000 in 1997, and
       $190,000 in 1996.

    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.

    In determining the accumulated benefit obligation for health care, at
    December 31, 1998 and 1997, health care inflation cost was assumed to
    increase at an annual rate of 7.5 percent, decreasing one percent per year
    to 4.5 percent in 2002 and thereafter. A one percentage-point increase in
    the assumed health care cost trend rate would increase the aggregate service
    and interest cost components of periodic benefit cost for 1998 by $42,000
    and the benefit obligation by $364,000, while a one percentage-point
    decrease in the assumed rate would decrease the 1998 cost components by
    $39,000 and the benefit obligation by $338,000.

NOTE 16 - INCENTIVE PLANS

    STOCK INCENTIVE PLAN

    The Company's 1996 Stock Incentive Plan ("the Plan") permits annual awards
    of shares of the Company's Common Stock to executives and other key
    employees. Under the Plan, the Executive Compensation Committee ("the
    Committee") is authorized to grant: (1) stock options, nonqualified or
    incentive; (2) stock appreciation rights; and (3) restricted stock awards.
    Total annual options granted, excluding any replacement options issued due
    to the spin-off from Murphy Oil, may not exceed .5 percent of Common shares
    issued and outstanding as of the date of issuance of the options. In
    subsequent years, the Committee may award up to .5 percent of Common shares
    issued and outstanding at the end of the preceding year; any allowed shares
    not granted may be available for grant in subsequent years. The Company
    applies APB 25 to account for stock-based compensation plans. Cost of
    options are accrued over the vesting periods and adjusted for subsequent
    changes in fair market value of the shares.

    Stock Options -- For each option granted under the Plan, the Committee fixes
       the option price at no less than fair market value on the date of the
       grant and the option term, not to exceed 10 years from date of grant.
       Replacement options granted were for 10 years from original grant date
       and nonqualified. Options granted in 1998 and 1997 were for 10 years and
       primarily incentive. All options have an option price no less than the
       fair market value on the grant date, with a range in option prices of
       $9.90 to $28.03 per share, and each grantee is permitted to surrender
       options for equivalent value of stock at the date of surrender. For
       options granted in 1998, one half may be exercised or surrendered after
       one year and the remainder after three years. For options granted in
       1997, exclusive of replacement options, one half may be exercised or
       surrendered after two years and the remainder after three years.

    Stock Appreciation Rights  --  Stock appreciation rights may be granted in
       conjunction with, or independent of, stock options. The Committee
       determines when these rights may be exercised and the price. No stock
       appreciation rights have been granted.

    Restricted Stock  --  The Committee may award restricted stock to selected
       employees, with conditions to vesting for each grant established by the
       Committee. 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. The grantee may be reimbursed by the Company for personal
       income tax liability on the value of stock awarded.

       During 1998, initial grants of 13,500 shares of restricted stock were
       awarded by the Committee. The fair value per share of restricted stock
       granted was $28.03. Unearned compensation was charged for the market
       value of the restricted shares. The unearned compensation is shown as a
       reduction of shareholders' equity in the Consolidated Balance Sheet at
       December 31, 1998, as Unamortized Restricted Stock Awards, and is being
       amortized to expense over the four-year restricted period.

    Stock-based compensation reflected in income was a benefit of $163,000 in
    1998 and a charge of $491,000 in 1997. Had cost of the Company's stock-based
    compensation plans been determined based on the fair value of the
    instruments at the grant dates using the provisions of SFAS 123, the
    Company's net income and earnings per share would be the following pro forma

</TABLE> 

    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 1998 and 1997, respectively: dividend yields of .70 percent and .90
    percent; expected volatility of 25.22 percent and 26.39 percent; risk-free
    interest rates of 5.74 percent and 6.38 percent; and expected lives of five
    years. Using these assumptions, the weighted average grant-date fair value
    per share of options granted in 1998 and 1997 were $8.62 and $6.65,
    respectively.

    INCENTIVE COMPENSATION PLAN

    Cash Awards -- The Company has an Incentive Compensation Plan that provides
       for annual cash awards to officers, directors, 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. Initial awards under the Plan were granted in
       1998, based on 1997 results of operations. Provisions for cash incentive
       awards of $270,000 and $425,000 were recorded in 1998 and 1997,
       respectively; no provisions were recorded in the 1996 Consolidated
       Statement of Income presented.

NOTE 17 - SUPPLEMENTAL CASH FLOWS DISCLOSURES

    Income taxes paid, net of refunds, were $5,753,000, $11,159,000, and
    $1,016,000 in 1998, 1997, and 1996, respectively. Federal income taxes for

                  Notes to Consolidated Financial Statements
                               December 31, 1998


    Options on 122,180 shares of Common Stock were not included in computing
    dilutive EPS for 1998 because their effects were antidilutive.

NOTE 19 - COMMITMENTS AND CONTINGENCIES

    Commitments  --  Commitments for capital expenditures at December 31, 1998,
       were approximately $205,000 for timber and timberlands; $4,091,000 for
       property, plant, and equipment; and $7,965,000 for investment in real
       estate held for development and sale.

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

NOTE 20 - BUSINESS SEGMENTS

    In June 1997, the Financial Accounting Standards Board issued SFAS 131,
    Disclosures about Segments of an Enterprise and Related Information. SFAS
    131 supersedes and/or amends the business segment disclosures required under
    various preceding pronouncements, effective for fiscal years beginning after
    December 15, 1997, with earlier application encouraged. This new standard
    defines additional information to be disclosed for each reportable segment
    and requires that each operating segment for which an enterprise's chief
    operating decision maker regularly assesses performance be disclosed as a
    reportable segment. As a result, the Company has determined that its
    previous Forest Products segment should be divided into two separate
    reporting segments, Woodlands and Mills. Deltic elected to adopt SFAS 131
    effective for the first quarter of 1998. All 1997 and 1996 business segment
    information has been restated for comparative purposes.

    The Company's five reporting segments consist of Deltic's four 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 397,000 acres of Southern Pine
    timberland located 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.

    The Mills segment consists of Deltic's two sawmills which employ modern
    technology to convert timber, purchased from third parties or the Company's
    Woodlands segment, into finished 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 wholesalers and lumber treaters in the South
    and Midwest and used in residential construction, roof trusses, laminated
    beams, and remanufactured items.

    Real Estate operations, which currently include three separate real estate
    developments, add value to former timberland by developing it into upscale,
    planned residential and commercial developments. These developments, each of
    which is, or will be, 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 and commercial site sales. In addition,
    this segment currently leases office space to third parties in a building
    constructed by the Company in one of its developments and is in

    the process of constructing a retail center in which space will be leased to
    third-party retailers. This segment also manages a real estate brokerage
    subsidiary which currently generates commission revenue by reselling
    existing homesites in one of the Company developments.

    The Agriculture segment operates 37,000 acres of farmland in northeast
    Louisiana. Approximately 26,000 acres of the total are farmed by Deltic,
    while the majority of the remaining 11,000 acres are rented to third
    parties. Crops grown on Company-farmed acreage in 1998 were soybeans and
    corn. This business unit derives the majority of its revenues from sales of
    farm crops grown to grain elevators and from rents received from third-party
    farmland renters.

    Corporate operations consist primarily of the planning, accounting,
    information systems, human resources, 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 equity in
    the 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.

    Information about the Company's business segments consisted of the

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

The Shareholders
Deltic Timber Corporation:


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 generally accepted accounting principles appropriate in the
circumstances. In preparing the financial statements, management has, when
necessary, made judgments and estimates with consideration given to materiality.

The Company maintains internal control systems and related policies and
procedures designed to provide reasonable assurance that assets are safeguarded
against loss or unauthorized use, that the accounting records accurately reflect
business transactions, and that the transactions are in accordance with
management's authorization. The design, monitoring, and revision of the systems
of internal control involve, among other things, our judgment with respect to
the relative cost and expected benefits of specific control measures. The
Company has engaged an outside accounting firm to provide internal audit
services in order to monitor the effectiveness of the controls, while
independently and systematically evaluating and formally reporting on the
adequacy and effectiveness of components of the system.

The Company's consolidated financial statements have been audited by KPMG LLP,
independent certified public accountants, who have expressed their opinion with
respect to the fairness of the consolidated financial statements. Their audit
was conducted in accordance with generally accepted auditing standards, which
include the consideration of the Company's internal controls to the extent
necessary to form an independent opinion on the consolidated financial
statements prepared by management. The Board of Directors appoints the
independent auditors; ratification of the appointment is solicited annually from
the shareholders.

The Audit Committee of the Board of Directors is composed of directors who are
not officers or employees of the Company. The Committee meets periodically with
the independent certified public accountants, the firm providing internal audit
services, and representatives of management to review the Company's internal
controls, the quality of its financial reporting, and the scope and results of
audits. The independent auditors have unrestricted access to the Committee,
without management's presence, to discuss audit findings and other financial
matters.

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

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, 1998 and 1997, and the related
consolidated statements of income, stockholders' equity, and cash flows for each
of the years in the three-year period ended December 31, 1998. 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 generally accepted auditing
standards. 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, 1998 and 1997, and the results
of their operations and their cash flows for each of the years in the three-year
period ended December 31, 1998, in conformity with generally accepted accounting
principles.

The Shareholders
Deltic Timber Corporation:


The members of the Company's Audit Committee ("the Committee") are selected by
the Board of Directors. The Committee consists of five outside directors and met
twice during 1998.

The Audit Committee oversees the financial reporting process on behalf of the
Board of Directors. As part of that responsibility, the Committee recommended to
the Board of Directors, subject to shareholder approval, the selection of the
Company's independent auditors. The Committee discussed the overall scope and
specific plans for annual audits with the outside accounting firm that provides
the Company's internal audit services and with KPMG LLP, the Company's
independent auditors. The Committee also discussed the Company's annual
consolidated financial statements and the adequacy of internal controls
currently in place. In addition, the Committee met with the internal auditors
and KPMG LLP, without management present, to discuss the results of their
respective audits, their evaluations of the Company's internal controls, and the
overall quality of the Company's financial reporting. The meetings were also
designed to facilitate any private communication with the Committee desired by
the internal audit firm or the Company's independent auditors.

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, 1998 and 1997, and the related statements of operations, members'
capital, and cash flows for the years then ended.  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 audit.

We conducted our audits in accordance with generally accepted auditing
standards.  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, 1998 and 1997, and the results of its operations and its cash flows
for the years then ended, in conformity with generally accepted accounting
principles.

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 molding.

     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. The MDF
     Marketing Agreement shall be automatically extended for successive five
     year periods unless either party elects not to extend.

     The Company was considered to be a development stage enterprise for the
     year ended December 31, 1997. No substantial operations occurred prior to
     January 1, 1997.

     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, other than spare
     parts for which the specific identification method is used to determine
     cost.

                         Notes to Financial Statements
                          December 31, 1998 and 1997



     Debt Service Reserve Funds

     Debt service reserve funds consists of cash account balances, restricted
     under the Company's permanent credit facility, to be used solely to pay
     debt service to the extent sufficient funds are not available for such
     scheduled debt service payments in the Company operating account.

     Property, Plant, and Equipment

     Property, plant, and equipment is stated at cost less accumulated
     depreciation. Depreciation of buildings, 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 are as follows:

                   Buildings                     40 years
                   Land improvements             20 years
                   Machinery and equipment       15 years
                   Vehicles                      3 to 5 years

     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") No. 121, Accounting for the Impairment of Long-Lived
     Assets and for Long-Lived Assets to be Disposed Of, and accordingly the
     Company will record 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. The Company
     recorded no such impairment in 1998 or 1997.

     Deferred Debt Costs

     Deferred debt costs consists of various costs related to obtaining the
     permanent credit facility, the issuance of the Union County, Arkansas
     Taxable Industrial Development Bonds (Del-Tin Fiber Project) 1998 Series
     (the "Taxable Bonds"), and the substitution of the letters of credit
     supporting the Union County, Arkansas Solid Waste Disposal Revenue Bonds
     (Del-Tin Fiber Project) 1997 Series A & B (the "Tax Exempt Bonds"). (The
     Taxable Bonds and the Tax Exempt Bonds are collectively called the
     "Bonds".) Such costs are stated on the 1998 Balance Sheet at original
     issuance cost, net of amortization on a straight-line basis over the life
     of the Bonds. (For additional information regarding the Company's financing
     arrangements, see Note 4 - Long-Term Debt Financing Arrangements.)

     Start-up Costs

     For 1998 and 1997, the Company expensed all costs related to the start-up
     of the Company.

     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.

     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 generally accepted accounting principles. Actual results
     could differ from those estimates.

     Reclassifications

     Certain 1997 amounts have been reclassified to conform with the 1998
     presentation.

     The scheduled maturities of required debt sinking fund deposits for the
     next five years are $1,045,750 in 2001, $4,972,875 in 2002, and $7,676,250
     in 2003. (For additional information regarding financial instruments, see
     Note 6 - Fair Value of Financial Instruments.)

     The Permanent Credit Facility

     In 1998, the Company entered into a permanent credit facility (the "Credit
     Facility") with several major banking institutions (the "Lenders") having a
     stated maturity of December 17, 2005 (the "Stated Maturity Date"). The
     Credit Facility provides a working capital commitment of $10,000,000 (the
     "Working Capital Commitment Amount") and a letter of credit commitment of
     $91,225,000 (the "Letter of Credit Commitment Amount") for a total
     commitment of $101,225,000. Both the working capital and the letter of
     credit

                         Notes to Financial Statements
                          December 31, 1998 and 1997



     commitments terminate on December 17, 2001 (the "Termination Date"), but
     the Termination Date for either or both commitments may be annually
     extended if the Company so requests and all the Lenders agree. In any case,
     the Termination Date may not be extended beyond the Stated Maturity Date.

     In connection with the Credit Facility, and with the issuance of the Bonds,
     the Company incurred approximately $1,638,000 in related costs. Such costs
     are included in the 1998 Balance Sheet in Deferred Debt Costs and are being
     amortized on a straight-line basis over the life of the Bonds.

          The Working Capital Commitment -- The Company may from time to time
          receiveworking capital loans from the Lenders, and the amount so
          loaned may be borrowed, repaid, and reborrowed at the Company's
          discretion. However, the aggregate amount of working capital loans
          outstanding must not be more than (1) the Working Capital Commitment
          Amount at any time; (2) $5 million for 30 consecutive days during
          1999; and (3) zero ($0) for 30 consecutive days in each following year
          of the working capital commitment. Any unpaid principal and interest
          on working capital loans is due and payable at the termination of the
          working capital loan commitment. At December 31, 1998, there was one
          working capital loan outstanding in the amount of $5,000,000, bearing
          interest at a rate of 6.955 percent.

          The Letter of Credit Commitment -- Three letters of credit have been
          issued pursuantto the Credit Facility in the aggregate stated amount
          of $89,824,657 as of December 31, 1998. The letters of credit have a
          stated expiration of December 17, 2001. Under the Credit Facility, the
          letters of credit may be extended to the extent that the Termination
          Date of the letter of credit commitment is extended. If the letters of
          credit expire before the Stated Maturity Date and are not renewed or
          replaced, the Lenders will make loans to the Company to purchase the
          Bonds. Any such loans would be finally due and payable at the Stated
          Maturity Date.

          The three letters of credit provide a payment mechanism for the Bonds
          and security for the Bondholders. Two of the letters of credit were
          issued to replace letters of credit supporting the Tax Exempt Bonds
          previously issued under the Interim Credit Facilities (described
          below) and the third was issued to provide initial letter of credit
          support for the Taxable Bonds. On December 31, 1998, the maximum
          amount available to be drawn was $14,639,041 under each of the two
          letters of credit supporting the Tax Exempt Bonds and $60,546,575
          under the letter of credit supporting the Taxable Bonds. The maximum
          amount available to be drawn under the letters of credit cover the
          principal amount of the relevant Bonds, plus an additional amount to
          cover interest.

          Security for the Permanent Credit Facility --Substantially all of the
          Company's assetsare pledged to the Lenders as security for the Credit
          Facility. The Credit Facility requires the Company to maintain debt
          service reserve funds in an amount equal to six months' debt service.
          The debt service to be reserved against includes all required payments
          for principal (other than for working capital loans), interest, and
          fees under

          both the Credit Facility and the Bonds. The funds in the debt service
          reserve bank accounts may be withdrawn solely to pay debt service to
          the extent sufficient funds are not available in the Company's
          operating account. The total amount in the debt service reserve funds
          as of December 31, 1998 was $4,183,957 and has been classified as
          noncurrent on the 1998 Balance Sheet due to the restriction placed on
          the funds.

          The Credit Facility requires the Company to make quarterly deposits
          into two sinking funds beginning in December of 2001. Failure to make
          such deposits is a default under the Credit Facility. The amount of
          the required deposits increases over the term of the Credit Facility,
          from $1,045,750 per quarter in December 2001, to $3,115,000 per
          quarter beginning in December 2005. In September 2006, the Company
          must deposit $49,662,000 into the sinking funds. The Company may not
          withdraw amounts deposited in the sinking funds during the term of the
          Credit Facility.

          As further security for the Credit Facility, each member has agreed
          (1) to provide to the Company up to $17,500,000 (for a combined total
          of $35,000,000) in the form of additional cash equity contributions or
          subordinated loans, if and to the extent, that the Company is in
          default under the Credit Facility; or a deficiency exists in the
          Credit Facility debt service reserve funds or sinking funds; and (2)
          to pay to the Company in the form of additional cash equity
          contributions or subordinated loans, the member's prorata portion of
          the difference between the Company's projected operating cash flow at
          90 percent of rated capacity, and the Company's projected operating
          cash flow at the production rate actually achieved by the Company (the
          "Operating Cash Flow Variance"), if, and to the extent that, the
          Company still does not have sufficient funds to pay debt service. The
          members will no longer be obligated to pay the Operating Cash Flow
          Variance once the plant successfully completes a minimum production
          test, planned for the summer of 1999.

     The Bonds

        The Bonds were issued by Union County, Arkansas, to finance the
        completion of the construction of the Company's MDF plant, as well as
        the acquisition, construction, and improvement of certain sewage 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 Bonds are 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 (both described below) 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.

        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 maximum interest rate for the
        Tax Exempt Bonds is ten percent and 9.5 percent for

                          December 31, 1998 and 1997



        the Taxable Bonds. The interest rate on the Tax Exempt Bonds at December
        31, 1998 and 1997 was 4.2 percent and 3.8 percent, respectively. The
        interest rate on the Taxable Bonds at December 31, 1998 was 5.7 percent.

        The Company has the right to convert the interest rate payable on the
        Bonds to either a flexible daily, term, or fixed rate, as defined in the
        trust indentures for the respective Bonds.

        Union County issued the Tax Exempt Bonds in October 1997 which were
        issued in two series, Series A and Series B, each in the amount of
        $14,500,000. In conjunction with this bond issuance, the Company and
        Union County entered into a loan agreement (the "Loan Agreement") which
        obligates the Company to make loan payments in the amount required to
        pay the debt service on the Tax Exempt Bonds. The Tax Exempt Bonds were
        originally supported by letters of credit (the "Interim Letters of
        Credit") issued pursuant to the Interim Credit Facilities. As described
        above, two letters of credit were issued in December 1998 pursuant to
        the Credit Facility, which replaced the Interim Letters of Credit. The
        Interim Letters of Credit were canceled prior to December 31, 1998.

        In December 1998, Union County issued the Taxable Bonds, in the amount
        of $60,000,000. The Company and Union County contemporaneously entered
        into a lease agreement (the "Lease Agreement") that obligates the
        Company to make lease payments in an amount necessary to fund the debt
        service on the Taxable Bonds. As described above, a letter of credit was
        issued under the Credit Facility to support the Taxable Bonds.

     The Interim Credit Facilities

        Prior to the funding of the Credit Facility, the Company was a party to
        three interim credit facilities (the "Interim Credit Facilities"). The
        payment terms and fees and interest payable under each interim credit
        facility were identical. Borrowings bore interest based upon prime or
        other various cost of funds options. Facility fees accrued at .05
        percent per annum for the unused commitment balances and .20 percent per
        annum for letters of credit and were payable quarterly. As of December
        31, 1998, no amounts were outstanding, and no letters of credit were
        issued, against any Interim Credit Facility.

        The Company is party with a group of major banks to an Interim Credit
        Facility totaling $40,000,000. At December 31, 1998, there were no
        amounts outstanding under either the letters of credit or line of credit
        portion of this Interim Credit Facility. At December 31, 1997, there
        were $14,639,000 in letters of credit outstanding under this agreement
        and $22,000,000 outstanding under the revolving line of credit. This
        Interim Credit Facility is supported by an unconditional guarantee of
        Deltic and expires December 31, 2001. The Company intends to terminate
        this facility during 1999.

                          December 31, 1998 and 1997



        During 1997 and 1998, the Company was a party with a bank to an Interim
        Credit Facility totaling $65,000,000. At December 31, 1998, this Interim
        Credit Facility had been terminated. At December 31, 1997, there was
        $14,639,000 in letters of credit outstanding under this agreement and
        $30,100,000 outstanding under the term loan. The $30,100,000 is included
        in current liabilities in the 1997 Balance Sheet. This Interim Credit
        Facility was supported by unconditional guaranties of Temple-Inland
        Forest Products Corporation. The obligations of Temple-Inland Forest
        Products Corporation under its guarantee are guaranteed by Temple-
        Inland, Inc.

        During 1997 and 1998, the Company was a party with Deltic to an Interim
        Credit Facility. At December 31, 1998, this Interim Credit Facility had
        been terminated. At December 31, 1997, there was $8,100,000 outstanding
        under this revolving line of credit Interim Credit Facility.

Note 5  -  Funds Held by Trustee

     At December 31, 1998 and 1997, the Company had funds held by the trustee
     related to the Union County, Arkansas Solid Waste Disposal Bonds Project
     1997 Series A and B that were restricted for construction purposes and can
     be released for payment upon the submission of qualified construction
     expenditures. At December 31, 1998 and 1997, the funds consisted of money
     market funds totaling $23,059 and $140,181, respectively, and investments
     in New York City municipal bonds totaling $3,300,000 and $9,800,000,
     respectively. The bonds are variable rate and reset weekly, with a maturity
     date of February 15, 2016. The balance has been classified as noncurrent
     due to the restriction placed on the funds. At December 31, 1998, the bonds
     were priced at par, which approximates fair value.

</TABLE>

     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, Accounts Payable, Retainage Payable, Accrued Expenses and
          Other, and Note Payable - Deltic Timber Corporation -- The carrying
          amounts approximate fair value because of the short maturity of these
          instruments.

        . Debt Service Reserve Funds -- The carrying amount approximates fair
          value since the interest earned on these deposits fluctuates with
          changes in current market rates.

        . Funds Held by Trustee -- The balance at December 31, 1998, consisted
          of money market funds and New York City municipal bonds. The money
          market funds are cash equivalents and the carrying amount approximates
          fair value. The fair value of the bonds is based on quoted market
          prices and at December 31, 1998 and 1997, the bonds are recorded at
          fair value.

                          December 31, 1998 and 1997



        . Long-term debt, including current maturities -- The carrying amount
          approximates fair value based on either the short-term maturity of the
          instrument or variable rates offered that approximate current market
          rates.

        . Letters of credit -- The fair value approximates the notional amount,
          which is based on the estimated cost to settle these obligations.

Note 7  -  Lease Commitments

     The Company is obligated under noncancelable operating leases for various
     equipment.

     December 31, 1998, the Company's balance due Temple-Inland for these
     services totaled $40,154.

Note 9  -  Supplemental Cash Flows Disclosures

     Interest paid, net of amounts capitalized, was $2,548,434 in 1998. Noncash
     investing and financing activities, excluded from the Statements of Cash
     Flows, were: (1) assumptions of accounts payable of $4,048,411 in 1998 and
     $13,060,741 in 1997 related to capital expenditures for additions of
     property, plant, and equipment and (2) non-cash capital contributions by
     the members during 1998 for payment of debt amounting to $4,500,000 and for
     debt costs paid on behalf of the Company of $1,179,594.

Note 10  -  Year 2000

     In 1998, the Company initiated a plan ("Plan") to identify, assess, and
     remediate Year 2000 issues within each of its significant computer programs
     and certain equipment which contain micro-processors. The Plan is
     addressing the issue of computer programs and embedded computer chips being
     unable to distinguish between the year 1900 and the year 2000, if a program
     or chip uses only two digits rather than four to define the applicable
     year. Systems which have been determined not to be Year 2000 compliant are
     being either replaced or reprogrammed, and thereafter tested for Year 2000
     compliance.

     The Company is in the process of identifying and contacting critical
     suppliers and customers whose computerized systems interface with the
     Company's systems, regarding their plans and progress in addressing their
     Year 2000 issues. The Company has received varying information from such
     third parties on the state of compliance or expected compliance.
     Contingency plans are being developed in the event that any critical
     supplier or customer is not compliant.

     The failure to correct a material Year 2000 problem could result in an
     interruption in, or a failure of, certain normal business activities or
     operations. Such failures could materially and adversely affect the
     Company's operations, liquidity, and financial condition. Due to the
     general uncertainty inherent in the Year 2000 problem, resulting in part
     from the uncertainty of the Year 2000 readiness of third-party suppliers
     and customers, the Company is unable to determine at this time whether the
     consequences of Year 2000 failures will have a material impact on the
     Company's operations, liquidity, or financial condition.

To the Purchaser Named on
the Signature Page Hereto


Ladies and Gentlemen:

         DELTIC TIMBER CORPORATION, a Delaware corporation (together with its
successors and assigns, the "COMPANY"), agrees with you as follows:

 1.      AUTHORIZATION OF NOTES.

         The Company will authorize the issue and sale of $40,000,000 aggregate
principal amount of its 6.66% Senior Notes due December 18, 2008 (the "NOTES",
such term to include any such notes issued in substitution therefor pursuant to
Section 13 of this Agreement). The Notes shall be substantially in the form set
out in Exhibit 1, with such changes therefrom, if any, as may be approved by you
and the Company. Certain capitalized terms used in this Agreement are defined in
Schedule B; references to a "Schedule" or an "Exhibit" are, unless otherwise
specified, to a Schedule or an Exhibit attached to this Agreement. The payment
by the Company of the principal of, Make Whole Amount, if any, and interest on
the Notes shall be unconditionally guaranteed, as provided in Section 10.13, by
the Subsidiary Guarantors pursuant to a Subsidiary Guarantee substantially in
the form of Exhibit B(SG) hereto.

 2.      SALE AND PURCHASE OF NOTES.

         Subject to the terms and conditions of this Agreement, the Company will
issue and sell to you and you will purchase from the Company, at the Closing
provided for in Section 3, Notes in the principal amount specified below your
name in Schedule A at the purchase price of 100% of the principal amount
thereof.

 3.      CLOSING.

         The sale and purchase of the Notes to be purchased by you shall occur
at the offices of Hebb & Gitlin, One State Street, Hartford, Connecticut 06103,
at 10:00 a.m., local time, at a closing (the "CLOSING") on December 18, 1998 or
on such other Business Day as may be agreed upon in writing by the Company and
you. At the Closing the Company will deliver to you the Notes to be purchased by
you in the form of a single Note (or such greater number of Notes in
denominations of at least $1,000,000 as you may request), dated the date of the
Closing, and registered in your name (or in the name of your nominee) as
indicated in Schedule A, against payment by federal funds wire transfer in
immediately available funds of the amount of the purchase price therefor as
directed by the Company in Schedule 3. If at the Closing the Company shall fail
to tender such Notes to you as provided above in this Section 3, or any of the
<PAGE>
 
conditions specified in Section 4 shall not have been fulfilled to your
reasonable satisfaction, you shall, at your election, be relieved of all further
obligations under this Agreement, without thereby waiving any rights you may
have by reason of such failure or such nonfulfillment.

4.       CONDITIONS TO CLOSING.

         Your obligation to purchase and pay for the Notes to be sold to you at
the Closing is subject to the fulfillment to your reasonable satisfaction, prior
to or at the Closing, of the following conditions:

         The representations and warranties of the Company in this Agreement
shall be correct when made and at the time of the Closing.

         4.4      PERFORMANCE; NO DEFAULT.

         The Company shall have performed and complied with all agreements and
conditions contained in this Agreement required to be performed or complied with
by it prior to or at the Closing and after giving effect to the issue and sale
of the Notes (and the application of the proceeds thereof as contemplated by
Schedule 5.14) no Default or Event of Default shall have occurred and be
continuing. Neither the Company nor any Subsidiary shall have entered into any
transaction since the date of the Memorandum that would have been prohibited by
Section 10.1 had such Section applied since such date.

         4.6      COMPLIANCE CERTIFICATES.

                  (B)  OFFICER'S CERTIFICATE. The Company shall have delivered

         to the authorization, execution and delivery of the Notes and this
         Agreement.

         may reasonably request.

         4.8      OPINIONS OF COUNSEL.

         to deliver such opinion to you).

         4.9      PURCHASE PERMITTED BY APPLICABLE LAW, ETC.

         On the date of the Closing your purchase of Notes shall (a) be
permitted by the laws and regulations of each jurisdiction to which you are
subject, without recourse to provisions (such as section 1405(a)(8) of the New

without restriction as to the character of the particular investment, (b) not
violate any applicable law or regulation (including, without limitation,
Regulation T, U or X of the Board of Governors of the Federal Reserve System)
and (c) not subject you to any tax, penalty or liability under or pursuant to
any applicable law or regulation, which law or regulation was not in effect on
the date hereof. If requested by you, you shall have received an Officer's
Certificate certifying as to such matters of fact as you may reasonably specify
to enable you to determine whether such purchase is so permitted.

         4.11     SUBSIDIARY GUARANTEE.

         Each of Deltic Timber Purchasers, Inc., an Arkansas corporation, and
Chenal Properties, Inc., an Arkansas corporation, shall have executed and

its jurisdiction of incorporation or been a party to any merger or consolidation
and shall not have succeeded to all or any substantial part of the liabilities
of any other entity, at any time following the date of the most recent financial
statements referred to in Schedule 5.5.

 5.      REPRESENTATIONS AND WARRANTIES OF THE COMPANY.

         The Company represents and warrants to you, as of the date of the
Closing, that:

         5.2      ORGANIZATION; POWER AND AUTHORITY.

         The Company is a corporation duly organized, validly existing and in
good standing under the laws of its jurisdiction of incorporation, and is duly
qualified as a foreign corporation and is in good standing in each jurisdiction
in which such qualification is required by law, other than those jurisdictions
as to which the failure to be so qualified or in good standing could not,
individually or in the aggregate, reasonably be expected to have a Material
Adverse Effect. The Company has the corporate power and authority to own or hold
under lease the properties it purports to own or hold under lease, to transact
the business it transacts and proposes to transact, to execute and deliver this
Agreement and the Notes and to perform the provisions hereof and thereof.

         5.3      AUTHORIZATION, ETC.

                  (a)  This Agreement and the Notes have been duly authorized by
         all necessary corporate action on the part of the Company, and this
         Agreement constitutes, and upon execution and delivery thereof each
         Note will constitute, a legal, valid and binding obligation of the
         Company enforceable against the Company in accordance with its terms,
         except as such enforceability may be limited by (a) applicable
         bankruptcy, insolvency, reorganization, moratorium or other similar
         laws affecting the enforcement of creditors' rights generally and (b)
         general principles of equity (regardless of whether such enforceability
         is considered in a proceeding in equity or at law).

                  (b)  The Subsidiary Guarantee has been duly authorized by all
         necessary corporate action on the part of each Subsidiary Guarantor
         and, upon execution and delivery thereof, the Subsidiary Guarantee will
         constitute, a legal, valid and binding obligation of each Subsidiary
         Guarantor, enforceable against each such Subsidiary Guarantor in
         accordance with its terms, except as such enforceability may be limited
         by (i) applicable bankruptcy, insolvency, reorganization, moratorium or
         other similar laws affecting the enforcement of creditors' rights
         generally and (ii) general principles of equity (regardless of whether
         such enforceability is considered in a proceeding in equity or at law)
         and public policy.

         5.5      DISCLOSURE.

         The Company, through the Placement Agent, has delivered to you a copy
of a Private Placement Memorandum, dated November 1998 (the "MEMORANDUM"),
relating to the transactions contemplated hereby. The Memorandum fairly
describes, in all material respects, the general nature of the business and
principal properties of the Company and its Subsidiaries.

Except as disclosed in Schedule 5.3, this Agreement, the Memorandum, the
documents, certificates or other writings delivered to you by or on behalf of
the Company in connection with the transactions contemplated hereby and the
financial statements listed in Schedule 5.5, taken as a whole, do not contain
any untrue statement of a material fact or omit to state any material fact
necessary to make the statements therein not misleading in light of the
circumstances under which they were made. Except as disclosed in the Memorandum
or as expressly described in Schedule 5.3, or in one of the documents,
certificates or other writings delivered to you by or on behalf of the Company
in connection with the transactions contemplated hereby, or in the financial
statements listed in Schedule 5.5, since December 31, 1997, there has been no
change in the financial condition, operations, business, properties or prospects
of the Company or any Subsidiary except changes that individually or in the
aggregate could not reasonably be expected to have a Material Adverse Effect.
There is no fact known to the Company that could reasonably be expected to have
a Material Adverse Effect that has not been set forth herein or in the
Memorandum or in the other documents, certificates and other writings delivered
to you by or on behalf of the Company specifically for use in connection with
the transactions contemplated hereby.

         5.7      ORGANIZATION AND OWNERSHIP OF SHARES OF SUBSIDIARIES;

         and correct lists of (i) the Company's Subsidiaries, showing, as to
         each Subsidiary, the correct name thereof, the jurisdiction of its
         organization, the percentage of shares of each class of its capital
         stock or similar equity interests outstanding owned by the Company and
         each other Subsidiary and whether such Subsidiary is a Subsidiary
         Guarantor as of the date of the Closing, and (ii) the Company's
         Affiliates, other than Subsidiaries.

                  (b)  All of the outstanding shares of capital stock or similar
         equity interests of each Subsidiary shown in Schedule 5.4 as being
         owned by the Company and its Subsidiaries have been validly issued, are
         fully paid and nonassessable and are owned by the Company or another
         Subsidiary free and clear of any Lien (except as otherwise disclosed in
         Schedule 5.4).

                  (c)  Each Subsidiary identified in Schedule 5.4 is a
         corporation or other legal entity duly organized, validly existing and
         in good standing under the laws of its jurisdiction of organization,
         and is duly qualified as a foreign corporation or other legal entity
         and is in good standing in each jurisdiction in which such
         qualification is required by law, other than those jurisdictions as to
         which the failure to be so qualified or in good standing could not,
         individually or in the aggregate, reasonably be expected to have a
         Material Adverse Effect. Each such Subsidiary has the corporate or
         other power and authority to own or hold under lease the properties it
         purports to own or hold under lease and to transact the business it
         transacts and proposes to transact. Each Subsidiary Guarantor has the
         corporate power and authority to execute and deliver the Subsidiary
         Guarantee and to perform the provisions thereof.

                  (d)  No Subsidiary is a party to, or otherwise subject to any
         legal restriction or any agreement (other than this Agreement, the
         agreements listed in Schedule 5.4 and customary limitations imposed by
         corporate law statutes) restricting the ability of such Subsidiary to
         pay dividends out of profits or make any other similar distributions of
         profits to the Company or any of its Subsidiaries that owns outstanding
         shares of capital stock or similar equity interests of such Subsidiary.

         Neither the execution, delivery and performance by the Company of this
Agreement and the Notes nor the execution, delivery and performance of the
Subsidiary Guarantee by the Subsidiary Guarantors will

                  (a)  contravene, result in any breach of, or constitute a
         default under, or result in the creation of any Lien in respect of any
         property of the Company or any Subsidiary under, any indenture,
         mortgage, deed of trust, loan, purchase or credit agreement, lease,
         corporate charter or by-laws, or any other agreement or instrument to
         which the Company or any Subsidiary is bound or by which the Company or
         any Subsidiary or any of their respective properties may be bound or
         affected

                  (b)  conflict with or result in a breach of any of the terms,
         conditions or provisions of any order, judgment, decree, or ruling of
         any court, arbitrator or Governmental Authority applicable to the
         Company or any Subsidiary, or

                  (c)  violate any provision of any statute or other rule or
         regulation of any Governmental Authority applicable to the Company or
         any Subsidiary.

         5.11     GOVERNMENTAL AUTHORIZATIONS, ETC.

         No consent, approval or authorization of, or registration, filing or
declaration with, any Governmental Authority is required in connection with the

declaration with, any Governmental Authority is required in connection with the
execution, delivery or performance by each Subsidiary Guarantor of the
Subsidiary Guarantee.

         5.13     LITIGATION; OBSERVANCE OF AGREEMENTS, STATUTES AND ORDERS.

                  (a)  Except as disclosed in Schedule 5.8, there are no
         actions, suits or proceedings pending or, to the knowledge of the
         Company, threatened against or affecting the Company or any Subsidiary
         or any property of the Company or any Subsidiary in any court or before
         any arbitrator of any kind or before or by any Governmental Authority
         that, individually or in the aggregate, could reasonably be expected to
         have a Material Adverse Effect.

                                       6
<PAGE>
 
                  (b)  Neither the Company nor any Subsidiary is in default
         under any term of any agreement or instrument to which it is a party or
         by which it is bound, or any order, judgment, decree or ruling of any
         court, arbitrator or Governmental Authority or is in violation of any
         applicable law, ordinance, rule or regulation (including, without
         limitation, Environmental Laws) of any Governmental Authority, which
         default or violation, individually or in the aggregate, could
         reasonably be expected to have a Material Adverse Effect.

         5.15     TAXES.

         The Company and its Subsidiaries have filed all tax returns that are
required to have been filed in any jurisdiction, and have paid all taxes shown
to be due and payable on such returns and all other taxes and assessments levied
upon them or their properties, assets, income or franchises, to the extent such
taxes and assessments have become due and payable and before they have become
delinquent, except for any taxes and assessments (a) the amount of which is not
individually or in the aggregate Material or (b) the amount, applicability or
validity of which is currently being contested in good faith by appropriate
proceedings and with respect to which the Company or a Subsidiary, as the case
may be, has established adequate reserves in accordance with GAAP. The Company
knows of no basis for any other tax or assessment that could reasonably be
expected to have a Material Adverse Effect. The charges, accruals and reserves
on the books of the Company and its Subsidiaries in respect of Federal, state or
other taxes (and in respect of any payment pursuant to any tax sharing
agreement) for all fiscal periods are adequate.

         5.17     TITLE TO PROPERTY; LEASES.

         The Company and its Subsidiaries have good and sufficient title to
their respective properties that individually or in the aggregate are Material,
including all such properties reflected in the most recent audited balance sheet
referred to in Section 5.5 or purported to have been acquired by the Company or
any Subsidiary after said date (except as sold or otherwise disposed of in the
ordinary course of business), in each case free and clear of Liens prohibited by
this Agreement. All leases that individually or in the aggregate are Material
are valid and subsisting and are in full force and effect in all material
respects.

         5.18     LICENSES, PERMITS, ETC.

         Except as disclosed in Schedule 5.11,

                  (a)  the Company and its Subsidiaries own or possess all
         licenses, permits, franchises, authorizations, patents, copyrights,
         service marks, trademarks and trade names, or rights thereto, that
         individually or in the aggregate are Material, without known conflict
         with the rights of others;

                  (b)  to the best knowledge of the Company, no product of the
         Company or any Subsidiary infringes in any material respect any
         license, permit, franchise, authorization, patent, copyright, service
         mark, trademark, trade name or other right owned by any other Person;
         and

                  (c)  to the best knowledge of the Company, there is no
         Material violation by any Person of any right of the Company or any of
         its Subsidiaries with respect to any

                                       7
<PAGE>
 
patent, copyright, service mark, trademark, trade name or other right owned or
used by the Company or any of its Subsidiaries.

         5.20     COMPLIANCE WITH ERISA.

                   (a) The Company and each ERISA Affiliate have operated and
         administered each Plan in compliance with all applicable laws except
         for such instances of noncompliance as have not resulted in and could
         not reasonably be expected to result in a Material Adverse Effect.
         Neither the Company nor any ERISA Affiliate has incurred any liability
         pursuant to Title I or IV of ERISA in the nature of a penalty or excise
         tax or the penalty or excise tax provisions of the Code relating to
         employee benefit plans (as defined in section 3 of ERISA), and no
         event, transaction or condition has occurred or exists that could
         reasonably be expected to result in the incurrence of any such
         liability by the Company or any ERISA Affiliate, or in the imposition
         of any Lien on any of the rights, properties or assets of the Company
         or any ERISA Affiliate, in either case pursuant to Title I or IV of
         ERISA or to such penalty or excise tax provisions or to section 401
         (a)(29) or 412 of the Code, other than such liabilities or Liens as
         would not be individually or in the aggregate Material.

                  (b)  The present value of the aggregate benefit liabilities
         under each of the Plans subject to Title IV of ERISA (other than
         Multiemployer Plans), determined as of the end of each such Plan's most
         recently ended plan year on the basis of the actuarial assumptions
         specified for funding purposes in such Plan's most recent actuarial
         valuation report, did not exceed the aggregate current value of the
         assets of such Plan allocable to such benefit liabilities. The term
         "BENEFIT LIABILITIES" has the meaning specified in section 4001 of
         ERISA and the terms "CURRENT VALUE" and "PRESENT VALUE" have the
         meaning specified in section 3 of ERISA.

                  (c)  The Company and the ERISA Affiliates have not incurred
         withdrawal liabilities (and are not subject to contingent withdrawal
         liabilities) under section 4201 or 4204 of ERISA in respect of
         Multiemployer Plans that individually or in the aggregate are Material.

                  (d)  The expected postretirement benefit obligation
         (determined as of the last day of the Company's most recently ended
         fiscal year in accordance with Financial Accounting Standards Board
         Statement No. 106, without regard to liabilities attributable to
         continuation coverage mandated by section 4980B of the Code) of the
         Company and its Subsidiaries is not Material.

                  (e)  The execution and delivery of this Agreement and the
         issuance and sale of the Notes hereunder will not involve any
         transaction that is subject to the prohibitions of section 406 of ERISA
         or in connection with which a tax could be imposed pursuant to section
         4975(c)(1)(A)-(D) of the Code. The representation by the Company in the
         first sentence of this Section 5.12(e) is made in reliance upon and
         subject to the accuracy of your representation in Section 6.2 as to the
         Sources used to pay the purchase price of the Notes to be purchased by
         you.

                  (f)  Schedule 5.12 sets forth all ERISA Affiliates and all
         "employee benefit plans" maintained by the Company (or any "affiliate"
         thereof) or in respect of which the Notes could constitute an "employer
         security" ("EMPLOYEE BENEFIT PLAN" has the meaning

                                       8
<PAGE>
 
         specified in section 3 of ERISA, "AFFILIATE" has the meaning specified
         in section 407(d) of ERISA and section V of the Department of Labor
         Prohibited Transaction Exemption 95-60 (60 FR 35925, July 12, 1995) and
         "EMPLOYER SECURITY" has the meaning specified in section 407(d) of
         ERISA)

         5.22    PRIVATE OFFERING BY THE COMPANY.

         Neither the Company nor anyone acting on its behalf has offered the
Notes or any similar securities for sale to, or solicited any offer to buy any
of the same from, or otherwise approached or negotiated in respect thereof with,
any Person other than you, an Institutional Investor who was offered the Notes
at a private sale for investment. Neither the Company nor anyone acting on its
behalf has taken, or will take, any action that would subject the issuance or
sale of the Notes to the registration requirements of section 5 of the
Securities Act.

         5.24     USE OF PROCEEDS; MARGIN REGULATIONS.

         The Company will apply the proceeds of the sale of the Notes as set
forth in Schedule 5.14. No part of the proceeds from the sale of the Notes
hereunder will be used, directly or indirectly, for the purpose of buying or
carrying any margin stock within the meaning of Regulation U of the Board of
Governors of the Federal Reserve System (12 CFR 221), or for the purpose of
buying or carrying or trading in any securities under such circumstances as to
involve the Company in a violation of Regulation X of said Board (12 CFR 224) or
to involve any broker or dealer in a violation of Regulation T of said Board (12
CFR 220). Margin stock does not constitute more than 5% of the value of the
consolidated assets of the Company and its Subsidiaries and the Company does not
have any present intention that margin stock will constitute more than 5% of the
value of such assets. As used in this Section, the terms "margin stock" and
"purpose of buying or carrying" shall have the meanings assigned to them in said
Regulation U.

         5.26     EXISTING DEBT; FUTURE LIENS.

                  (a)  Except as described therein, Schedule 5.15 sets forth a
         complete and correct list of all outstanding Debt of the Company and
         its Subsidiaries as of October 31, 1998 (and specifying, as to each
         such Debt, the collateral, if any, securing such Debt), since which
         date there has been no Material change in the amounts, interest rates,
         sinking funds, instalment payments or maturities of the Debt of the
         Company or its Subsidiaries. Neither the Company nor any Subsidiary is
         in default and no waiver of default is currently in effect, in the
         payment of any principal or interest on any Debt of the Company or such
         Subsidiary and no event or condition exists with respect to any Debt of
         the Company or any Subsidiary that would permit (or that with notice or
         the lapse of time, or both, would permit) one or more Persons to cause
         such Debt to become due and payable before its stated maturity or
         before its regularly scheduled dates of payment.

                  (b)  Except as disclosed in Schedule 5.15, neither the Company
         nor any Subsidiary has agreed or consented to cause or permit in the
         future (upon the happening of a contingency or otherwise) any of its
         property, whether now owned or hereafter acquired, to be subject to a
         Lien not permitted by Section 10.8(a).

         5.27     FOREIGN ASSETS CONTROL REGULATIONS, ETC.

                                       9
<PAGE>
 
         Neither the sale of the Notes by the Company hereunder nor its use of
the proceeds thereof will violate the Trading with the Enemy Act, as amended, or
any of the foreign assets control regulations of the United States Treasury
Department (31 CFR, Subtitle B, Chapter V, as amended) or any enabling
legislation or executive order relating thereto.

         5.29     STATUS UNDER CERTAIN STATUTES.

         Neither the Company nor any Subsidiary is subject to regulation under
the Investment Company Act of 1940, as amended, the Public Utility Holding
Company Act of 1935, as amended, the Transportation Acts (49 U.S.C.), as
amended, or the Federal Power Act, as amended.

         5.31    ENVIRONMENTAL MATTERS.

         Neither the Company nor any Subsidiary has knowledge of any claim or
has received any notice of any claim, and no proceeding has been instituted
raising any claim against the Company or any of its Subsidiaries or any of their
respective real properties now or formerly owned, leased or operated by any of
them or other assets, alleging any damage to the environment or violation of any
Environmental Laws, except, in each case, such as could not reasonably be
expected to result in a Material Adverse Effect. Except as disclosed in Schedule
5.18

                  (a)  neither the Company nor any Subsidiary has knowledge of
         any facts which would give rise to any claim, public or private, of
         violation of Environmental Laws or damage to the environment emanating
         from, occurring on or in any way related to real properties now or
         formerly owned, leased or operated by any of them or to other assets or
         their use, except, in each case, such as could not reasonably be
         expected to result in a Material Adverse Effect;

                  (b)  neither the Company nor any of its Subsidiaries has
         stored any Hazardous Materials on real properties now or formerly
         owned, leased or operated by any of them or disposed of any Hazardous
         Materials in a manner contrary to any Environmental Laws in each case
         in any manner that could reasonably be expected to result in a Material
         Adverse Effect; and

                  (c)  all buildings on all real properties now owned, leased or
         operated by the Company or any of its Subsidiaries are in compliance
         with applicable Environmental Laws, except where failure to comply
         could not reasonably be expected to result in a Material Adverse
         Effect.

         5.33     YEAR 2000 COMPLIANCE.

         The Company has reviewed the areas within the business and operations
of the Company and each Subsidiary that could be adversely affected by, and has
developed or is developing programs to address on a timely basis, the "Year 2000
Problem" (that is, the risk that computer applications, as well as embedded
microchips in non-computing devices, used by the Company or any Subsidiary may
be unable to recognize and perform properly date-sensitive functions involving
certain dates prior to and any date after December 31,1999). Based on such
review and program, the Company reasonably believes that the "Year 2000 Problem"
will not result in a Material Adverse Effect. At the request of any holder of
Notes, the Company agrees

                                       10
<PAGE>
 
to provide such holder with copies of all filings and other disclosures made by
the Company pursuant to the Exchange Act and the regulations promulgated
thereunder with respect to the "Year 2000 Problem."

6.       REPRESENTATIONS OF THE PURCHASER.

         6.2      PURCHASE FOR INVESTMENT.

         You represent that you are purchasing the Notes for your own account or
for one or more separate accounts maintained by you or for the account of one or
more pension or trust funds and not with a view to the distribution thereof,
provided that the disposition of your or their property shall at all times be
within your or their control. You understand that the Notes have not been
registered under the Securities Act and may be resold only if registered
pursuant to the provisions of the Securities Act or if an exemption from
registration is available, except under circumstances where neither such
registration nor such an exemption is required by law, and that the Company is
not required to register the Notes.

         6.4      SOURCE OF FUNDS.

         You represent that at least one of the following statements is an
accurate representation as to each source of funds (a "Source") to be used by
you to pay the purchase price of the Notes to be purchased by you hereunder:

                  (a)  the Source is an "insurance company general account" as
         defined in United States Department of Labor Prohibited Transaction
         Exemption ("PTE") 95-60 (60 FR 35925, July 12, 1995) and in respect
         thereof you represent that there is no "employee benefit plan" (as
         defined in section 3(3) of ERISA and section 4975(e)(1) of the Code,
         treating as a single plan all plans maintained by the same employer or
         employee organization or affiliate thereof) with respect to which the
         amount of the general account reserves and liabilities of all contracts
         held by or on behalf of such plan exceeds 10% of the total reserves and
         liabilities of such general account (exclusive of separate account
         liabilities) plus surplus, as set forth in the National Association of
         Insurance Commissioners' Annual Statement filed with your state of
         domicile and that such acquisition is eligible for and satisfies the
         other requirements of such exemption; or

                  (b)  if you are an insurance company, the Source does not
         include assets allocated to any separate account maintained by you in
         which any employee benefit plan (or its related trust) has any
         interest, other than a separate account that is maintained solely in
         connection with your fixed contractual obligations under which the
         amounts payable, or credited, to such plan and to any participant or
         beneficiary of such plan (including any annuitant) are not affected in
         any manner by the investment performance of the separate account; or

                  (c)  the Source is either (i) an insurance company pooled
         separate account, within the meaning of PTE 90-1 (issued January
         29,1990), or (ii) a bank collective investment fund, within the meaning
         of the PTE 91-38 (issued July 12, 1991) and, except as you have
         disclosed to the Company in writing pursuant to this paragraph (c), no
         employee benefit plan or group of plans maintained by the same employer
         or employee organization beneficially owns more than 10% of all assets
         allocated to such pooled separate account or collective investment
         fund; or

                                       11
<PAGE>
 
                  (d)  the Source constitutes assets of an "investment fund"
         (within the meaning of part V of PTE 84-14 (the "QPAM EXEMPTION"))
         managed by a "qualified professional asset manager" or "QPAM" (within
         the meaning of part V of the OPAM Exemption), no employee benefit
         plan's assets that are included in such investment fund, when combined
         with the assets of all other employee benefit plans established or
         maintained by the same employer or by an affiliate (within the meaning
         of section V(c)(1) of the QPAM Exemption) of such employer or by the
         same employee organization and managed by such QPAM, exceed 20% of the
         total client assets managed by such QPAM, the conditions of part 1(c)
         and (g) of the QPAM Exemption are satisfied, neither the QPAM nor a
         person controlling or controlled by the QPAM (applying the definition
         of "control" in section V(e) of the QPAM Exemption) owns a 5% or more
         interest in the Company and

                       (i)    the identity of such QPAM and

                       (ii)   the names of all employee benefit plans whose
               assets are included in such investment fund

         have been disclosed to the Company in writing pursuant to this
paragraph (d); or

                  (e)  the Source is a governmental plan; or

                  (f)  the Source is one or more employee benefit plans, or a

          provisions of the Code relating to employee benefit plans, or in the

     covered by the statements then being furnished to the date of the
     certificate and that such review has not disclosed the existence during
     such period of any condition or event that constitutes a Default or an
     Event of Default or, if any such condition or event existed or exists
     (including, without limitation, any such event or condition resulting from
     the failure of the Company or any Subsidiary to comply with any
     Environmental Law), specifying the nature and period of existence thereof
     and what action the Company shall have taken or proposes to take with
     respect thereto.

     7.6  INSPECTION.

     The Company shall permit the representatives of each holder of Notes
that is an Institutional Investor:

          (B)  No Default -- if no Default or Event of Default then exists, at

     be requested.

8.   PAYMENT OF THE NOTES.

     8.2  REQUIRED PREPAYMENT; PAYMENT AT MATURITY.

     There shall be no scheduled principal prepayments on account of the Notes.
The unpaid principal amount of each Note, together with accrued unpaid interest
thereon, shall be due and payable on December 18, 2008.

     8.4  OPTIONAL PREPAYMENTS WITH MAKE-WHOLE AMOUNT.

     The Company may, at its option, upon notice as provided below, prepay at
any time all, or from time to time any part of, the Notes, on a pro rota basis
in respect of all Notes outstanding at such time, in an amount not less than 5%
of the aggregate principal amount of the Notes then outstanding in the case of a
partial prepayment, at 100% of the principal amount so prepaid and accrued
interest thereon to the date of prepayment, plus the Make-Whole Amount, if any,
determined for the prepayment date with respect to the principal amount of Notes
being so prepaid. The Company will give each holder of Notes written notice of
each optional prepayment under this Section 8.2 not less than 30 days and not
more than 60 days prior to the date fixed for such prepayment. Each such notice
shall specify such prepayment date, the aggregate principal amount of the Notes
to be prepaid on such date, the principal amount of each Note held by such
holder to be prepaid (determined in accordance with Section 8.3), and the
interest to be paid on the prepayment date with respect to such principal amount
being prepaid, and shall be accompanied by a certificate of a Senior Financial
Officer as to the estimated Make-Whole Amount, if any, due in connection with
such prepayment (calculated as if the date of such notice were the date of the
prepayment), setting forth the details of such computation. Two Business Days
prior to such prepayment, the Company shall deliver to each holder of Notes a
certificate of a Senior Financial Officer specifying the calculation of such
Make-Whole Amount, if any, as of the specified prepayment date.

     8.6  ALLOCATION OF PARTIAL PREPAYMENTS.

     In the case of each partial prepayment of the Notes, the principal amount
of the Notes to be prepaid shall be allocated among all of the Notes at the time
outstanding in proportion, as nearly as practicable, to the respective unpaid
principal amounts thereof not theretofore called for prepayment. All partial
prepayments made pursuant to Section 8.6 with respect to a Change in Control
shall be applied as provided for in Section 8.4.

     8.7  MATURITY; SURRENDER, ETC.

     In the case of each prepayment of Notes pursuant to this Section 8, the
principal amount of each Note to be prepaid shall mature and become due and
payable on the date fixed for such prepayment, together with interest on such
principal amount accrued to such date and the applicable Make-Whole Amount, if
any. From and after such date, unless the Company shall fail to pay such
principal amount when so due and payable, together with the interest and Make-

                                      16
<PAGE>
 
Whole Amount, if any, as aforesaid, interest on such principal amount shall
cease to accrue. Any Note paid or prepaid in full shall be surrendered to the
Company and cancelled and shall not be reissued, and no Note shall be issued in
lieu of any prepaid principal amount of any Note.

     Any prepayment of Notes in respect of a Change in Control under Section 8.6
shall be on terms as set forth in said Section 8.6, provided that only those
holders who shall have accepted the offer under said Section 8.6 shall have
their Notes prepaid in whole in connection therewith. Any Debt Prepayment
Application shall be on terms as set forth in Section 8.2 and this Section 8.4.

     8.9   NO OTHER OPTIONAL PREPAYMENTS OR PURCHASE OF NOTES.

     The Company will not and will not permit any Affiliate to purchase, redeem,
prepay or otherwise acquire, directly or indirectly, any of the outstanding
Notes except upon the payment or prepayment of the Notes in accordance with the
terms of this Agreement and the Notes. The Company will promptly cancel all
Notes acquired by it or any Affiliate pursuant to any payment, prepayment or
purchase of Notes pursuant to any provision of this Agreement and no Notes may
be issued in substitution or exchange for any such Notes.

     8.10  OFFER TO PREPAY UPON CHANGE IN CONTROL, ETC.

           (A)  NOTICE AND OFFER. In the event of either

                (i)    a Change in Control, or

                (ii)   the obtaining of actual knowledge of a Control Event by a
           Senior Financial Officer,

     the Company will, within five Business Days of the occurrence of either of
     such events, give written notice of such Change in Control or Control Event
     to each holder of Notes by facsimile transmission and, simultaneously with
     the sending of such facsimile notice, send a copy of such notice to each
     such holder via an overnight courier of national reputation. Such written
     notice shall contain, and such written notice shall constitute, an
     irrevocable offer to prepay all, but not less than all, the Notes held by
     such holder on a date specified in such notice (the "CONTROL PREPAYMENT
     DATE") that is not less than 60 days and not more than 90 days after the
     date of such notice, provided that, in the case of a Control Event that
     does not give rise to a Change in Control, such notice shall be null and
     void and in the case of a Control Event that does give rise to a Change in
     Control which shall occur more than 90 days following the date the written
     notice required by this Section 8.6(a) must be given, the Control
     Prepayment Date may be delayed by the Company to a date not later than the
     date on which the Change in Control arising from such Control Event shall
     actually be consummated or finalized. If the Control Prepayment Date shall
     not be specified in such notice, the Control Prepayment Date shall be the
     60th day after the date of such notice; it being understood by the parties
     hereto, for purposes of the avoidance of doubt, that any such notice shall
     be dated the date on which it is first given to the holders of Notes and
     that all notices to all holders of Notes shall bear the same date.

           If the Company shall not have received a written response to such
     written notice from any holder of Notes within 10 days after the date of
     the facsimile transmission of

                                       17
<PAGE>
 
     such notice to such holder, the Company shall use its best efforts to send
     a second written notice via an overnight courier of national reputation to
     such holder of Notes but shall be under no obligation to do so.

           (B)   ACCEPTANCE AND PAYMENT; ACCEPTANCE.

                 (i)    ACCEPTANCE AND PAYMENT. To accept or reject such offered
           prepayment, a holder of Notes shall cause a notice of such acceptance
           or rejection to be delivered to the Company not later than 30 days
           after the date of the notice constituting such offered prepayment
           (which, if there shall have been two written notices, shall be deemed
           to be the first written notice). If so accepted, such offered
           prepayment in respect of such principal amount of such Notes shall be
           due and payable on the Control Prepayment Date. Such offered
           prepayment shall be made at 100% of the principal amount of the Notes
           held by holders having accepted such offer, together with interest on
           the Notes then being prepaid accrued to the Control Prepayment Date
           and the applicable Make-Whole Amount, if any.

                 (ii)   REJECTION. A failure by any holder of Notes to respond
           in writing to all written offers of prepayment referred to in Section
           8.6(b) by the deadlines set forth therein shall be deemed to
           constitute a rejection of such offer by such holder.

           (C)   OFFICER'S CERTIFICATE. Each offer to prepay the Notes pursuant
     to this Section 8.6 shall be accompanied by a certificate, executed by a
     Senior Financial Officer and dated the date of such offer, specifying:

                 (i)    the Control Prepayment Date;

                 (ii)   that such offer is being made pursuant to this Section
           8.6 and that failure by a holder to respond to such offer by the
           deadlines as established by this Section 8.6 shall result in such
           offer to such holder being deemed rejected;

                 (iii)  the interest that would be due on each such Note offered
           to be prepaid, accrued to the date fixed for payment;

                 (iv)   a calculation of the estimated Make-Whole Amount due in
           connection with such prepayment (calculated as if the date of such
           notice were the date of the prepayment), setting forth the details of
           such computation;

                 (v)    that the conditions of this Section 8.6 have been
           fulfilled; and

                 (vi)   in reasonable detail, a description of the nature and
           date or proposed date of the Change in Control.

           (D)   CALCULATION OF MAKE-WHOLE AMOUNT. Two Business Days prior to
     the Control Prepayment Date, the Company shall deliver to each holder of
     Notes that has accepted an offer of prepayment under this Section 8.6 a
     certificate of a Senior Financial Officer specifying the calculation of
     such Make-Whole Amount, if any, as of the Control Prepayment Date.

           (E)   CANCELLATION OF NOTES. Any Note acquired by the Company under
     this Section 8.6 shall be cancelled and shall not be reissued.

     8.11  MAKE-WHOLE AMOUNT.

     The term "MAKE-WHOLE AMOUNT" means, with respect to any Note, an amount
equal to the excess, if any, of the Discounted Value of the Remaining Scheduled
Payments with respect to the Called Principal of such Note over the amount of
such Called Principal, provided that the Make-Whole Amount may in no event be
less than zero. For the purposes of determining the Make-Whole Amount, the
following terms have the following meanings:

          "CALLED PRINCIPAL" means, with respect to any Note, the principal of
     such Note that is to be prepaid pursuant to Section 8.2 or Section 8.6, or
     has become or is declared to be immediately due and payable pursuant to
     Section 12.2, as the context requires.

           "DISCOUNTED VALUE" means, with respect to the Called Principal of any
     Note, the amount obtained by discounting all Remaining Scheduled Payments
     with respect to such Called Principal from their respective scheduled due
     dates to the Settlement Date with respect to such Called Principal, in
     accordance with accepted financial practice and at a discount factor
     (applied on the same periodic basis as that on which interest on the Notes
     is payable) equal to the Reinvestment Yield with respect to such Called
     Principal.

          "REINVESTMENT YIELD" means, with respect to the Called Principal of
     any Note, the sum of (a) 0.50% per annum plus (b) the yield to maturity
     implied by (i) the yields reported, as of 10:00 a.m. (New York City time)
     on the second Business Day preceding the Settlement Date with respect to
     such Called Principal, on the display designated as "Page U.S.D." of the
     Bloomberg Financial Markets Services Screen (or, if not available, any
     other nationally recognized trading screen reporting on-line intraday
     trading in the U.S. Treasury securities) for actively traded U.S. Treasury
     securities having a maturity equal to the Remaining Average Life of such
     Called Principal as of such Settlement Date, or (ii) if such yields are not
     reported as of such time or the yields reported as of such time are not
     ascertainable (including by interpolation), the Treasury Constant Maturity
     Series Yields reported, for the latest day for which such yields have been
     so reported as of the second Business Day preceding the Settlement Date
     with respect to such Called Principal, in Federal Reserve Statistical
     Release H.15 (519) (or any comparable successor publication) for actively
     traded U.S. Treasury securities having a constant maturity equal to the
     Remaining Average Life of such Called Principal as of such Settlement Date.
     Such implied yield will be determined, if necessary, by (1) converting U.S.
     Treasury bill quotations to bond-equivalent yields in accordance with
     accepted financial practice and (2) interpolating linearly between (A) the
     actively traded U.S. Treasury security with the maturity closest to and
     greater than the Remaining Average Life and (B) the actively traded U.S.
     Treasury security with the maturity closest to and less than the Remaining
     Average Life.

          "REMAINING AVERAGE LIFE" means, with respect to any Called Principal,
     the number of years (calculated to the nearest one-twelfth year) obtained
     by dividing

               (i)   such Called Principal into

               (ii)  the sum of the products obtained by multiplying

                                       19
<PAGE>
 
                     (a) the principal component of each Remaining Scheduled
               Payment with respect to such Called Principal by

                     (b) the number of years (calculated to the nearest one-
               twelfth year) that will elapse between the Settlement Date with
               respect to such Called Principal and the scheduled due date of
               such Remaining Scheduled Payment.

          "REMAINING SCHEDULED PAYMENTS" means, with respect to the Called
     Principal of any Note, all payments of such Called Principal and interest
     thereon that would be due after the Settlement Date with respect to such
     Called Principal if no payment of such Called Principal were made prior to
     its scheduled due date, provided that if such Settlement Date is not a date
     on which interest payments are due to be made under the terms of the Notes,
     then the amount of the next succeeding scheduled interest payment will be
     reduced by the amount of interest accrued to such Settlement Date and
     required to be paid on such Settlement Date pursuant to Section 8.2,
     Section 8.6 or Section 12.1.

          "SETTLEMENT DATE" means, with respect to the Called Principal of any
     Note, the date on which such Called Principal is to be prepaid pursuant to
     Section 8.2 or Section 8.6 or has become or is declared to be immediately
     due and payable pursuant to Section 12.1, as the context requires.

9.   AFFIRMATIVE COVENANTS.

     The Company covenants that so long as any of the Notes are outstanding:

     9.2  COMPLIANCE WITH LAW.

     The Company will and will cause each of its Subsidiaries to comply with
all laws, ordinances or governmental rules or regulations to which each of them
is subject, including, without limitation, Environmental Laws, and will obtain
and maintain in effect all licenses, certificates, permits, franchises and other
governmental authorizations necessary to the ownership of their respective
properties or to the conduct of their respective businesses, in each case to the
extent necessary to ensure that non-compliance with such laws, ordinances or
governmental rules or regulations or failures to obtain or maintain in effect
such licenses, certificates, permits, franchises and other governmental
authorizations could not, individually or in the aggregate, reasonably be
expected to have a Material Adverse Effect.

     9.4  INSURANCE.

     The Company will and will cause each of its Subsidiaries to maintain,
with financially sound and reputable insurers, insurance with respect to their
respective properties and businesses against such casualties and contingencies,
of such types, on such terms and in such amounts (including deductibles,
co-insurance and self-insurance, if adequate reserves are maintained with
respect thereto) as is customary in the case of entities of established
reputations engaged in the same or a similar business and similarly situated.

     The Company will and will cause each of its Subsidiaries to maintain and
keep, or cause to be maintained and kept, their respective properties in good
repair, working order and condition (other than ordinary wear and tear), so that
the business carried on in connection therewith may be properly conducted at all
times, provided that this Section shall not prevent the Company or any
Subsidiary from discontinuing the operation and the maintenance of any of its
properties if such discontinuance is desirable in the conduct of its business
and the Company has concluded that such discontinuance could not, individually
or in the aggregate, reasonably be expected to have a Material Adverse Effect.

     9.8  PAYMENT OF TAXES AND CLAIMS.

     The Company will and will cause each of its Subsidiaries to file all
tax returns required to be filed in any jurisdiction and to pay and discharge
all taxes shown to be due and payable on such returns and all other taxes,
assessments, governmental charges, or levies imposed on them or any of their
properties, assets, income or franchises, to the extent such taxes, assessments,
charges or levies have become due and payable and before they have become
delinquent and all claims for which sums have become due and payable that have
or might become a Lien on properties or assets of the Company or any Subsidiary,
provided that neither the Company nor any Subsidiary need pay any such tax or
assessment or claims if (a) the amount, applicability or validity thereof is
contested by the Company or such Subsidiary on a timely basis in good faith and
in appropriate proceedings, and the Company or a Subsidiary has established
adequate reserves therefor in accordance with GAAP on the books of the Company
or such Subsidiary or (b) the nonpayment of all such taxes, assessments, charges
and levies in the aggregate could not reasonably be expected to have a Material
Adverse Effect.

     9.9  CORPORATE EXISTENCE, ETC.

     The Company will at all times preserve and keep in full force and
effect its corporate existence. Subject to Sections 10.2, and 10.9, the Company
will at all times preserve and keep in full force and effect the corporate
existence of each of its Subsidiaries (unless merged into the Company or a
Wholly-Owned Subsidiary) and all rights and franchises of the Company and its
Subsidiaries unless, in the good faith judgment of the Company, the termination
of or failure to preserve and keep in full force and effect such corporate
existence, right or franchise could not, individually or in the aggregate, have
a Material Adverse Effect.

transactions to any Person (except that (x) any Subsidiary may consolidate or
merge with or into, or convey, transfer or lease all or substantially all of its

event, become) a Subsidiary Guarantor) and (y) any Subsidiary may transfer or
lease all or substantially all of its assets if permitted pursuant to Section

Guarantor shall have the effect of releasing such Subsidiary Guarantor from its
liability under the Subsidiary Guarantee except as provided in Section 10.13(c).

     Income (but only if a positive number) for each completed fiscal quarter of
     the Company beginning with the fiscal quarter ending December 31, 1998.

     10.5  LIMITATION ON CURRENT DEBT.

     The Company will not, and will not allow any Subsidiary to, have any
Current Debt outstanding on any date after the date of the Closing unless, for
any period of 30 consecutive days during the fiscal year of the Company most
recently ended prior to such time, the aggregate principal amount of
Consolidated Current Debt outstanding on each day during such 30 day period did
not exceed the amount of additional Consolidated Funded Debt which the Company
would have been permitted to incur on such day pursuant to Section 10.5(b).

     Debt of a Subsidiary owing to the Company or a Wholly-Owned Subsidiary, any
     Debt of a Person existing at the time such

     Subsidiary to, at any time, declare or make or incur any liability to
     declare or make any Restricted Payment unless immediately after giving
     effect to the proposed Restricted Payment no Default or Event of Default
     would exist.

           (D) AUTHORIZATION OF RESTRICTED PAYMENT. The Company will not, nor
     will it permit any Subsidiary to, authorize a Restricted Payment that is
     not payable within 60 days of authorization.

respect of goods or accounts receivable) of the Company or such Subsidiary,

     any Basket Transfer is applied to a Debt Prepayment Application and/or is
     applied to, or committed in writing to, a Property Reinvestment
     Application, in each case within 365 days (or, in the case of the Chenal
     Valley Transfer, within 730 days) after the consummation of such Transfer
     (and, in the case of any such commitment, such Property Reinvestment
     Application is actually consummated within 30 days after the expiration of
     such 365-day period, or such 730-day period, as the case may be), then such
     Basket Transfer (or, in the case of a partial application or partial
     commitment of such Net Proceeds Amount, a ratable portion of such Basket
     Transfer) shall be excluded from any calculations set forth above in
     subclause (iii) of this clause (d).

          For purposes of determining the book value of any asset that is the
subject of a Transfer, such book value shall be the net book value of such asset

Transfer, provided that, in the case of a Transfer of any capital stock or other
equity interests of a Subsidiary, the book value thereof shall be deemed to be
an amount equal to

           (A)  the remainder (determined after eliminating all inter-company
    transactions, assets and liabilities in accordance with GAAP) of

                (1)  the book value of the total net assets of such Subsidiary
     less

                (2)  the liabilities of such Subsidiary times

            (B)  a percentage that is equal to the percentage of total equity
     interests of such Subsidiary attributable to the capital stock or other
     equity interest being so Transferred.

     10.12  LINE OF BUSINESS.

     The Company will not and will not permit any Subsidiary to engage in any
business if, as a result, the general nature of the businesses in which the
Company and the Subsidiaries, taken as a whole, would then be engaged would be
substantially changed from the general nature of the businesses of the Company
and the Subsidiaries as described in the Memorandum.

     10.13  PAN PASSU OBLIGATIONS.

     The Company covenants that its obligations under the Notes and under

     Except as provided for in this Agreement, the Company will not, and

Person other than the Company or another Subsidiary which would restrict any
such Subsidiary's ability or right to pay dividends to, or make advances to or
Investments in, the Company or, if such Subsidiary is not directly owned by the
Company, the "parent" Subsidiary of such Subsidiary.

     10.16  MAINTENANCE OF GUARANTEES OF SUBSIDIARIES.

            (A)  ADDITIONAL SUBSIDIARY GUARANTORS -- Conformity to Certain Other
     Agreements. No Subsidiary will be or become a guarantor, obligor or co-
     obligor in respect of any bank credit facility of the Company unless such
     Subsidiary is already a party to, and a guarantor under, the Subsidiary
     Guarantee or unless such Subsidiary shall contemporaneously therewith
     become a party to, and a guarantor under, the Subsidiary Guarantee.

            (b)  DELIVERY OF SUBSIDIARY GUARANTEE. In connection with any
     Subsidiary becoming a Subsidiary Guarantor under clause (a) of this Section

     in the form thereof set forth in Exhibit B(SG), and (y) each of the
     documents, certificates and opinions described on Annex 3 to the Subsidiary
     Guarantor Accession Agreement (defined below) prepared with respect to such

      shall not be deemed to be a Subsidiary Guarantor hereunder and (ii) if the
      Subsidiary Guarantee is outstanding and in effect at such time, then the
      Company shall cause such Subsidiary to execute and deliver to each holder
      of Notes a Subsidiary Guarantor Accession Agreement, substantially in the
      form thereof set forth in Exhibit B(SGAA) (together with each of the

      ("SUBSIDIARY GUARANTOR ACCESSION AGREEMENT"), and until such Subsidiary
      Guarantor Accession Agreement is delivered to each of the holders of
      Notes, such Subsidiary shall not be deemed to be a Subsidiary Guarantor
      hereunder.

          (c)  RELEASE OF SUBSIDIARY GUARANTEE OF SUBSIDIARY GUARANTORS. If,
      with respect to any Subsidiary that is a Subsidiary Guarantor,

               (i)   all, or substantially all, of the assets of such Subsidiary
          Guarantor are Transferred in accordance with the requirements of
          Sections 10.2 and 10.9 and such Subsidiary Guarantor is wound-up and
          terminated in accordance with the requirements of Section 9.5 or is
          deemed, in the good faith opinion of a Senior Financial Officer, to
          not have material assets,

               (ii)  all of the Company's and any Subsidiary's capital shares or
          other equity ownership interests in such subsidiary Guarantor is

               (iii) such Subsidiary Guarantor is not required to be maintained
          as a Subsidiary Guarantor in order for the Company to remain in
          compliance with Section 10.13(a),

      then the Company may elect to cause the withdrawal of such Subsidiary
      Guarantor from the Subsidiary Guarantee and such Subsidiary Guarantor will
      thereby be deemed to be fully discharged from the Subsidiary Guarantee.
      Such election shall be exercised by a Senior Financial Officer (A)
      informing, in writing, each holder of Notes of such election, (B)
      certifying that the requirements of this Section 10.13(c) have been
      satisfied, (C) certifying that the requirements of Section 10.13(a) will
      be satisfied immediately after giving effect to the withdrawal and
      cessation of the Subsidiary Guarantor with respect to the Subsidiary
      Guarantee and (D) certifying that no Default or Event of Default exists.
      Thereafter, such Subsidiary Guarantor shall be discharged from the
      Subsidiary Guarantee and, at the Company's election and expense and upon
      the Company's reasonable request, the holders of the Notes will provide
      written confirmation of each such discharge. Any Subsidiary Guarantor that
      has been discharged is nonetheless available to again become a "Subsidiary
      Guarantor" in accordance with Section 10.13(a).

12.      REMEDIES ON DEFAULT, ETC.

         12.2     ACCELERATION.

                  (a)  If an Event of Default with respect to the Company
         described in paragraph (g) or paragraph (h) of Section 11 (other than
         an Event of Default described in clause (i) of paragraph (g) or
         described in clause (vi) of paragraph (g) by virtue of the fact that
         such clause encompasses clause (i) of paragraph (g)) has occurred, all
         the Notes then outstanding shall automatically become immediately due
         and payable.

                  (b)  If any other Event of Default has occurred and is
         continuing, any holder or holders of more than 33 and 1/3% in principal
         amount of the Notes at the time outstanding may at any time at its or
         their option, by notice or notices to the Company, declare all the
         Notes then outstanding to be immediately due and payable.

                  (c)  If any Event of Default described in paragraph (a) or (b)
         of Section 11 has occurred and is continuing, any holder or holders of
         Notes at the time outstanding affected by such Event of Default may at
         any time, at its or their option, by notice or notices to the Company,
         declare all the Notes held by it or them to be immediately due and
         payable.

         Upon any Notes becoming due and payable under this Section 12.1,
whether automatically or by declaration, such Notes will forthwith mature and
the entire unpaid principal amount of such Notes, plus (x) all accrued and
unpaid interest thereon and (y) the Make-Whole Amount determined in respect of
such principal amount (to the full extent permitted by applicable law), shall
all be immediately due and payable, in each and every case without presentment,
demand, protest or further notice, all of which are hereby waived. The Company
acknowledges, and the parties hereto agree, that each holder of a Note has the
right to maintain its investment in the Notes free from repayment by the Company
(except as herein specifically provided for) and that the provision for payment
of a Make-Whole Amount by the Company in the event that the Notes are prepaid or
are accelerated as a result of an Event of Default, is intended to provide
compensation for the deprivation of such right under such circumstances.

         12.4     OTHER REMEDIES.

         If any Default or Event of Default has occurred and is continuing, and
irrespective of whether any Notes have become or have been declared immediately
due and payable under Section 12.1, the holder of any Note at the time
outstanding may proceed to protect and enforce the rights of such holder by an
action at law, suit in equity or other appropriate proceeding, whether for the
specific performance of any agreement contained herein or in any Note, or for an
injunction against a violation of any of the terms hereof or thereof, or in aid
of the exercise of any power granted hereby or thereby or by law or otherwise.

         12.6     RESCISSION.

         At any time after any Notes have been declared due and payable pursuant
to clause (b) or clause (c) of Section 12.1, the holders of not less than 67% in
principal amount of the Notes then outstanding, by written notice to the
Company, may rescind and annul any such declaration and its consequences if (i)
the Company has paid all overdue interest on the Notes, all principal of and
Make-Whole Amount, if any, due and payable on any Notes other than by reason of
such

                                       34
<PAGE>
 
declaration, and all interest on such overdue principal and Make-Whole Amount,
if any, and (to the extent permitted by applicable law) any overdue interest in
respect of the Notes, at the Default Rate, (ii) all Events of Default and
Defaults, other than non-payment of amounts that have become due solely by
reason of such declaration, have been cured or have been waived pursuant to
Section 17, and (iii) no judgment or decree has been entered for the payment of
any monies due pursuant hereto or to the Notes. No rescission and annulment
under this Section 12.3 will extend to or affect any subsequent Event of Default
or Default or impair any right consequent thereon.

         12.7     NO WAIVERS OR ELECTION OF REMEDIES, EXPENSES, ETC.

         No course of dealing and no delay on the part of any holder of any Note
in exercising any right, power or remedy shall operate as a waiver thereof or
otherwise prejudice such holder's rights, powers or remedies. No right, power or
remedy conferred by this Agreement or by any Note upon any holder thereof shall
be exclusive of any other right, power or remedy referred to herein or therein
or now or hereafter available at law, in equity, by statute or otherwise.
Without limiting the obligations of the Company under Section 15, the Company
will pay to the holder of each Note on demand such further amount as shall be
sufficient to cover all costs and expenses of such holder incurred in any
enforcement or collection under this Section 12, including, without limitation,
reasonable attorneys' fees, expenses and disbursements.

13.      REGISTRATION; EXCHANGE; SUBSTITUTION OF NOTES.

         13.2     REGISTRATION OF NOTES.

         The Company shall keep at its principal executive office a register for
the registration and registration of transfers of Notes. The name and address of
each holder of one or more Notes, each transfer thereof and the name and address
of each transferee of one or more Notes shall be registered in such register.
Prior to due presentment for registration of transfer, the Person in whose name
any Note shall be registered shall be deemed and treated as the owner and holder
thereof for all purposes hereof, and the Company shall not be affected by any
notice or knowledge to the contrary. The Company shall give to any holder of a
Note that is an Institutional Investor promptly upon request therefor, a

         Except as set forth in the last sentence of this Section 13.2, upon

registration of transfer, duly endorsed or accompanied by a written instrument
of transfer duly executed by the registered holder of such Note or his attorney
duly authorized in writing and accompanied by the address for notices of each
transferee of such Note or part thereof), the Company shall execute and deliver,
at the Company's expense (except as provided below), one or more new Notes (as
requested by the holder thereof) in exchange therefor, in an aggregate principal
amount equal to the unpaid principal amount of the surrendered Note. Each such
new Note shall be payable to such Person as such holder may request and shall be
substantially in the form of Exhibit 1. Each such new Note shall be dated and
bear interest from the date to which interest shall have been paid on the
surrendered Note or dated the date of the surrendered Note if no interest shall
have been paid thereon. The Company may require payment of a sum sufficient to
cover any stamp tax or governmental

                                       35
<PAGE>
 
charge imposed in respect of any such transfer of Notes. Notes shall not be
transferred in denominations of less than $1,000,000, provided that if necessary
to enable the registration of transfer by a holder of its entire holding of
Notes, one Note may be in a denomination of less than $1,000,000. Any
transferee, by its acceptance of a Note registered in its name (or the name of
its nominee), shall be deemed to have made the representation set forth in
Section 6.2. Notwithstanding anything to the contrary contained herein, no Note
shall be transferred to a Competitor.

         13.6     REPLACEMENT OF NOTES.

         Upon receipt by the Company of evidence reasonably satisfactory to it
of the ownership of and the loss, theft, destruction or mutilation of any Note

such Institutional Investor of such ownership and such loss, theft, destruction
or mutilation), and

                  (a) in the case of loss, theft or destruction, of indemnity
         reasonably satisfactory to it (provided that if the holder of such Note
         is, or is a nominee for, an original Purchaser or another holder of a
         Note with a minimum net worth of at least $100,000,000, such Person's
         own unsecured agreement of indemnity shall be deemed to be
         satisfactory), or

                  (b) in the case of mutilation, upon surrender and cancellation
         thereof,

the Company at its own expense shall execute and deliver, in lieu thereof, a new

paid on such lost, stolen, destroyed or mutilated Note or dated the date of such
lost, stolen, destroyed or mutilated Note if no interest shall have been paid
thereon.

cancellation, reasonably promptly after any such request, to the

Company at its principal executive office or at the place of payment most
recently designated by the Company pursuant to Section 14.1. Prior to any sale
or other disposition of any Note held by you or your nominee you will, at your
election, either endorse thereon the amount of principal paid thereon and the
last date to which interest has been paid thereon or surrender such Note to the
Company in exchange for a new Note or Notes pursuant to Section 13.2. The
Company will afford the benefits of this Section 14.2 to any Institutional
Investor that is the direct or indirect transferee of any Note purchased by you
under this Agreement and that has made the same agreement relating to such Note
as you have made in this Section 14.2.

15.  EXPENSES, ETC.

     15.2     TRANSACTION EXPENSES.

     Whether or not the transactions contemplated hereby are consummated, the
Company will pay all costs and expenses (including reasonable attorneys' fees of
one special counsel and, if reasonably required, one local counsel) incurred
jointly by you and each other holder of a Note in connection with such
transactions and in connection with any amendments, waivers or consents under or
in respect of this Agreement or the Notes (whether or not such amendment, waiver
or consent becomes effective), including, without limitation: (a) the costs and
expenses incurred in enforcing or defending (or determining whether or how to
enforce or defend) any rights under this Agreement or the Notes or in responding
to any subpoena or other legal process or informal investigative demand issued

of any Note, and (b) the costs and expenses, including financial advisors' fees,
incurred in connection with the insolvency or bankruptcy of the Company or any

respect of any fees, costs or expenses if any, of brokers and finders (other
than those retained by you).

     15.4     SURVIVAL.

     The obligations of the Company under this Section 15 will survive the
payment or transfer of any Note, the enforcement, amendment or waiver of any
provision of this Agreement or the Notes, and the termination of this Agreement.

 16. SURVIVAL OF REPRESENTATIONS AND WARRANTIES; ENTIRE AGREEMENT.

     All representations and warranties contained herein shall survive the
execution and delivery of this Agreement and the Notes, the purchase or transfer
by you of any Note or portion thereof or interest therein and the payment of any
Note, and may be relied upon by any subsequent holder of a Note, regardless of
any investigation made at any time by or on behalf of you or any other holder of
a Note. All statements contained in any certificate or other instrument
delivered by or on behalf of the Company pursuant to this Agreement shall be
deemed representations and warranties of the Company under this Agreement.
Subject to the preceding sentence, this Agreement and the Notes embody the
entire agreement and understanding between you and the Company and supersede all
prior agreements and understandings relating to the subject matter hereof.

 17. AMENDMENT AND WAIVER.

     17.2  REQUIREMENTS.

     This Agreement and the Notes may be amended, and the observance of any
term hereof or of the Notes may be waived (either retroactively or
prospectively), with (and only with) the written consent of the Company and the
Required Holders, except that (a) no amendment or waiver of any of the
provisions of any of Sections 1, 2, 3, 4, 5, 6 and 21, or any defined term (as
it is used therein), will be effective as to you unless consented to by you in
writing, (b) no such amendment or waiver may, without the written consent of the
holder of each Note at the time outstanding affected thereby, (i) subject to the
provisions of Section 12 relating to acceleration or rescission, change the
amount or time of any prepayment or payment of principal of, or reduce the rate
or change the time of payment or method of computation of interest or of the
Make-Whole Amount on, the Notes and (ii) change the percentage of the principal
amount of the Notes the holders of which are required to consent to any such
amendment or waiver and (c) no such amendment or waiver may, without the written
consent of the holder of each Note at the time outstanding affected thereby
amend any of Sections 8,11(a), 11(b), 12, 17 and 20.

     17.4  SOLICITATION OF HOLDERS OF NOTES.

           (B) SOLICITATION. The Company will provide each holder of the Notes
     (irrespective of the amount of Notes then owned by it) with sufficient
     information, sufficiently far in advance of the date a decision is
     required, to enable such holder to make an informed and considered decision
     with respect to any proposed amendment, waiver or consent in respect of any
     of the provisions hereof or of the Notes. The Company will deliver executed
     or true and correct copies of each amendment, waiver or consent effected
     pursuant to the provisions of this Section 17 to each holder of outstanding
     Notes promptly following the date on which it is executed and delivered by,
     or receives the consent or approval of, the requisite holders of Notes.

           (D) PAYMENT. The Company will not directly or indirectly pay
     or cause to be paid any remuneration, whether by way of supplemental or
     additional interest, fee or otherwise, or grant any security, to any holder
     of Notes as consideration for or as an inducement to the entering into by
     any holder of Notes of any waiver or amendment of any of the terms and
     provisions hereof unless such remuneration is concurrently paid, or
     security is concurrently granted, on the same terms, ratably to each holder
     of Notes then outstanding even if such holder did not consent to such
     waiver or amendment.

            (C) CONSENT IN CONTEMPLATION OF TRANSFER. Any consent made
     pursuant to this Section 17 by a holder of Notes that has transferred or
     has agreed to transfer its Notes to the Company, any Subsidiary or any
     Affiliate of the Company and has provided or has agreed to provide such
     written consent as a condition to such transfer shall be void and of no
     force or effect except solely as to such holder, and any amendments
     effected or waivers granted or to be effected or granted that would not
     have been or would not be so effected or granted but for such consent (and
     the consents of all other holders of Notes that were acquired under the
     same or similar conditions) shall be void and of no force or effect except
     solely as to such holder.

     17.5   BINDING EFFECT, ETC.

     Any amendment or waiver consented to as provided in this Section 17 applies
equally to all holders of Notes and is binding upon them and upon each future
holder of any Note and upon

                                       38
<PAGE>
 
the Company without regard to whether such Note has been marked to indicate such
amendment or waiver. No such amendment or waiver will extend to or affect any
obligation, covenant, agreement, Default or Event of Default not expressly
amended or waived or impair any right consequent thereon. No course of dealing
between the Company and the holder of any Note nor any delay in exercising any
rights hereunder or under any Note shall operate as a waiver of any rights of
any holder of such Note. As used herein, the term "this Agreement" and
references thereto shall mean this Agreement as it may from time to time be
amended or supplemented.

     17.6   NOTES HELD BY COMPANY, ETC.

     Solely for the purpose of determining whether the holders of the requisite
percentage of the aggregate principal amount of Notes then outstanding approved
or consented to any amendment, waiver or consent to be given under this
Agreement or the Notes, or have directed the taking of any action provided
herein or in the Notes to be taken upon the direction of the holders of a
specified percentage of the aggregate principal amount of Notes then
outstanding, Notes directly or indirectly owned by the Company or any of its
Affiliates shall be deemed not to be outstanding.

18.  NOTICES.

     All notices and communications provided for hereunder shall be in
writing and sent (a) by telecopy if the sender on the same day sends a
confirming copy of such notice by a recognized overnight delivery service
(charges prepaid), or (b) by registered or certified mail with return receipt
requested (postage prepaid), or (c) by a recognized overnight delivery service
(with charges prepaid). Any such notice must be sent:

            (i)   if to you or your nominee, to you or it at the address
     specified for such communications in Schedule A, or at such other address
     as you or it shall have specified to the Company in writing,

            (ii)  if to any other holder of any Note, to such holder at such
     address as such other holder shall have specified to the Company in
     writing, or

            (iii) if to the Company, to the Company at its address set forth at
     the beginning hereof to the attention of Clefton D. Vaughan, telecopier:
     (870) 881-6457, or at such other address as the Company shall have
     specified to the holder of each Note in writing.

Notices under this Section 18 will be deemed given only when actually received.

19.  REPRODUCTION OF DOCUMENTS.

     This Agreement and all documents relating hereto, including, without
limitation, (a) consents, waivers and modifications that may hereafter be
executed, (b) documents received by you at the Closing (except the Notes
themselves), and (c) financial statements, certificates and other information
previously or hereafter furnished to you, may be reproduced by you by any
photographic, photostatic, microfilm, microcard, miniature photographic or other
similar process and you may destroy any original document so reproduced. The
Company agrees and stipulates that, to the extent permitted by applicable law,
any such reproduction shall be admissible in evidence as the original itself in
any judicial or administrative proceeding (whether or not the

                                       39
<PAGE>
 
original is in existence and whether or not such reproduction was made by you in
the regular course of business) and any enlargement, facsimile or further
reproduction of such reproduction shall likewise be admissible in evidence. This
Section 19 shall not prohibit the Company or any other holder of Notes from
contesting any such reproduction to the same extent that it could contest the
original, or from introducing evidence to demonstrate the inaccuracy of any such
reproduction.

20.  CONFIDENTIAL INFORMATION.

     For the purposes of this Section 20, "CONFIDENTIAL INFORMATION" means
information delivered to you by or on behalf of the Company or any Subsidiary in
connection with the transactions contemplated by or otherwise pursuant to this
Agreement, provided that such term does not include information that

            (a)  was publicly known or otherwise known to you prior to the
     time of such disclosure,

            (b)  subsequently becomes publicly known through no act or
     omission by you or any person acting on your behalf,

            (c)  otherwise becomes known to you other than through
     disclosure by the Company or any Subsidiary, or

            (d)  constitutes financial statements delivered to you under Section
     7.1 that are otherwise publicly available.

You will maintain the confidentiality of such Confidential Information in
accordance with procedures adopted by you in good faith to protect confidential
information of third parties delivered to you, provided that you may deliver or
disclose Confidential Information to:

            (i)   your directors, officers, trustees, employees, agents,
     attorneys and affiliates (to the extent such disclosure reasonably relates
     to the administration of the investment represented by your Notes),

            (ii)  your financial advisors and other professional advisors who
     agree to hold confidential the Confidential Information substantially in
     accordance with the terms of this Section 20,

            (iii)  any other holder of any Note,

            (iv)   any Institutional Investor to which you sell or offer to sell
     such Note or any part thereof or any participation therein (if such Person
     has agreed in writing prior to its receipt of such Confidential Information
     to be bound by the provisions of this Section 20),

            (v)    any Person from which you offer to purchase any security of
     the Company (if such Person has agreed in writing prior to its receipt of
     such Confidential Information to be bound by the provisions of this Section
     20),

            (vi)   any federal or state regulatory authority having jurisdiction
     over you,

                                       40
<PAGE>
 
            (vii)  the National Association of Insurance Commissioners or any
similar organization, or any nationally recognized rating agency that requires 
access to information about your investment portfolio or

            (viii) any other Person to which such delivery or disclosure may be
necessary or appropriate

                   (A)   to effect compliance with any law, rule, regulation or
             order applicable to you,

                   (B)   in response to any subpoena or other legal process,

                   (C)   in connection with any litigation to which you are a
             party, or

                   (D)   if an Event of Default has occurred and is continuing,
             to the extent you may reasonably determine such delivery and
             disclosure to be necessary or appropriate in the enforcement or for
             the protection of the rights and remedies under your Notes and this
             Agreement.

Each holder of a Note, by its acceptance of a Note, will be deemed to have
agreed to be bound by and to be entitled to the benefits of this Section 20 as
though it were a party to this Agreement. On reasonable request by the Company
in connection with the delivery to any holder of a Note of information required
to be delivered to such holder under this Agreement or requested by such holder
(other than a holder that is a party to this Agreement or its nominee), such
holder will enter into an agreement with the Company embodying the provisions of
this Section 20.

21.  SUBSTITUTION OF PURCHASER.

     You shall have the right to substitute any one of your Affiliates as the
purchaser of the Notes that you have agreed to purchase hereunder, by written
notice to the Company, which notice shall be signed by both you and such
Affiliate, shall contain such Affiliate's agreement to be bound by this
Agreement and shall contain a confirmation by such Affiliate of the accuracy
with respect to it of the representations set forth in Section 6. Upon receipt
of such notice, wherever the word "you" is used in this Agreement (other than in
this Section 21), such word shall be deemed to refer to such Affiliate in lieu
of you. In the event that such Affiliate is so substituted as a purchaser
hereunder and such Affiliate thereafter transfers to you all of the Notes then
held by such Affiliate, upon receipt by the Company of notice of such transfer,
wherever the word "you" is used in this Agreement (other than in this Section
21), such word shall no longer be deemed to refer to such Affiliate, but shall
refer to you, and you shall have all the rights of an original holder of the
Notes under this Agreement.

22.  MISCELLANEOUS.

     22.2   SUCCESSORS AND ASSIGNS.

     All covenants and other agreements contained in this Agreement by or on
behalf of any of the parties hereto bind and inure to the benefit of their
respective successors and assigns (including, without limitation, any subsequent
holder of a Note) whether so expressed or not.

                                       41
<PAGE>
 
     22.4   PAYMENTS DUE ON NON-BUSINESS DAYS.

     Anything in this Agreement or the Notes to the contrary notwithstanding,
any payment of principal of or Make-Whole Amount or interest on any Note that is
due on a date other than a Business Day shall be made on the next succeeding
Business Day without including the additional days elapsed in the computation of
the interest payable on such next succeeding Business Day.

     22.6   SEVERABILITY.

     Any provision of this Agreement that is prohibited or unenforceable in
any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of
such prohibition or unenforceability without invalidating the remaining
provisions hereof, and any such prohibition or unenforceability in any
jurisdiction shall (to the full extent permitted by law) not invalidate or
render unenforceable such provision in any other jurisdiction.

     22.8   CONSTRUCTION.

     Each covenant contained herein shall be construed (absent express provision
to the contrary) as being independent of each other covenant contained herein,
so that compliance with any one covenant shall not (absent such an express
contrary provision) be deemed to excuse compliance with any other covenant.
Where any provision herein refers to action to be taken by any Person, or which
such Person is prohibited from taking, such provision shall be applicable
whether such action is taken directly or indirectly by such Person.

     22.10  COUNTERPARTS.

     This Agreement may be executed in any number of counterparts, each of
which shall be an original but all of which together shall constitute one
instrument. Each counterpart may consist of a number of copies hereof, each
signed by less than all, but together signed by all, of the parties hereto.

     22.12  GOVERNING LAW.

     THIS AGREEMENT SHALL BE CONSTRUED AND ENFORCED IN ACCORDANCE WITH, AND
THE RIGHTS OF THE PARTIES SHALL BE GOVERNED BY, THE LAW OF THE STATE OF NEW YORK
EXCLUDING CHOICE-OF-LAW PRINCIPLES OF THE LAW OF SUCH STATE THAT WOULD REQUIRE
THE APPLICATION OF THE LAWS OF A JURISDICTION OTHER THAN SUCH STATE.

determination, the total of all Debt of all Subsidiaries outstanding, in each
case, on such date, after eliminating (without duplicative effect):

               (a)  any such Debt owing by any Subsidiary to the Company or any
          other Wholly-Owned Subsidiary;

               (b)  any such Debt owing by any Subsidiary that is a Subsidiary
          Guarantor; and

               (c)  any such Debt secured by Liens expressly permitted under
          clause (f), (h), (i) or (j) of Section 10.8.

          "AFFILIATE" means at any time, and with respect to any Person,

               (a)  any other Person that at such time directly or indirectly

As used in this definition, "Control" means the possession, directly or
indirectly, of the power to direct or cause the direction of the management and
policies of a Person, whether through the ownership of voting securities, by
contract or otherwise. Unless the context otherwise clearly requires, any

          (a)  any default, failure or delay, willful or otherwise, in the
     performance by the Company of any obligations of any kind or character
     whatsoever of the Company (including, without limitation, the obligations
     and undertakings of the Company under the Note Purchase Agreement);

          (b)  any creditors' rights, bankruptcy, receivership or other
     insolvency proceeding of the Company or any other Person or in respect of
     the property of the Company or any other Person or any merger,
     consolidation, reorganization, dissolution, liquidation or winding up of
     the Company or any other Person;

          (c)  impossibility or illegality of performance on the part of the
     Company of its obligations under the Note Purchase Agreement or under the
     Notes;

          (d)  the validity or enforceability of the Note Purchase Agreement or
     the Notes;

          (e)  in respect of the Company or any other Person, any change of
     circumstances, whether or not foreseen or foreseeable, whether or not
     imputable to the Company or any other Person, or other impossibility of
     performance through fire, explosion, accident, labor disturbance, floods,
     droughts, embargoes, wars (whether or not declared), civil commotions, acts
     of God or the public enemy, delays or failure of suppliers or carriers,
     inability to obtain materials, action of any regulatory body or agency,
     change of law or any other causes affecting performance, or any other force

<PAGE>
 
     department, official or administrative or regulatory agency of any thereof
     or any other action, happening, event or reason whatsoever which shall
     delay, interfere with, hinder or prevent, or in any way adversely affect,
     the performance by any party of its respective obligations under any
     instruments; or

          (g)  any other circumstance which might otherwise constitute a defense
     available to, or a discharge of, any Subsidiary Guarantor in respect of the
     obligations of such Subsidiary Guarantor under this Guarantee.

     2.9   NO ELECTION.

     Each holder of Notes shall have the right to seek recourse against each
Subsidiary Guarantor to the fullest extent provided for in this Guarantee and
against the Company to the fullest extent provided for in the Note Purchase
Agreement and the Notes. No election to proceed in one form of action or
proceeding, or against any party, or on any obligation, shall constitute a
waiver of the right of such holder of Notes to proceed in any other form of
action or proceeding or against other parties unless such holder of Notes has
expressly waived such right in writing. Specifically, but without limiting the
generality of the foregoing, no action or proceeding by any holder of Notes
against the Company or any Subsidiary Guarantor under any document or instrument
evidencing obligations of the Company or such Subsidiary Guarantor to such
holder of Notes shall serve to diminish the liability of any Subsidiary
Guarantor under this Guarantee except to the extent that such holder of Notes
finally and unconditionally shall have realized payment by such action or
proceeding, notwithstanding the effect of any such action or proceeding upon
such Subsidiary Guarantor's right of subrogation against the Company.

     2.10  OTHER ENFORCEMENT RIGHTS.

     Each holder of Notes may proceed to protect and enforce this Guarantee by
suit or suits or proceedings in equity, at law or in bankruptcy, and whether for
the specific performance of any covenant or agreement contained herein or in
execution or aid of any power herein granted or for the recovery of judgment for
or in respect of the Guaranteed Obligations or for the enforcement of any other
proper, legal or equitable remedy available under applicable law.

     2.11  DELAY OR OMISSION; NO WAIVER.

     No course of dealing on the part of any holder of Notes and no delay or
failure on the part of such holder to exercise any right under the Note Purchase
Agreement, the Notes or this Guarantee shall impair such right or operate as a
waiver of such right or otherwise prejudice such holder's rights, powers and
remedies hereunder. Every right and remedy given in or by this Guarantee or by
law to any holder of Notes may be exercised from time to time as often as may be
deemed expedient by such Person.

     2.12  RESTORATION OF RIGHTS AND REMEDIES.

     If any holder of Notes shall have instituted any proceeding to enforce any
right or remedy contained in this Guarantee, under the Note Purchase Agreement
or under any Note held by such holder and such proceeding shall have been
discontinued or abandoned for any reason, or shall have been determined
adversely to such holder, then and in every such case each such holder, the
Company and each Subsidiary Guarantor shall, except as may be limited or
affected by any determination in such proceeding, be restored severally and
respectively to its respective

                                Exhibit B(SG)-6
<PAGE>
 
former positions hereunder and thereunder, and thereafter the rights and
remedies of such holder shall continue as though no such proceeding had been
instituted.

     2.13  CUMULATIVE REMEDIES.

     No remedy under this Guarantee, the Note Purchase Agreement or the Notes is
intended to be exclusive of any other remedy, but each and every remedy shall be
cumulative and in addition to any and every other remedy given pursuant to this
Guarantee, the Note Purchase Agreement or the Notes.

     2.14  SURVIVAL.

     So long as the Guaranteed Obligations shall not have been fully and finally
performed and indefeasibly paid, the obligations of each Subsidiary Guarantor
under this Guarantee shall survive the transfer and payment of any Note and the
payment in full of all the Notes.

     2.15  MISCELLANEOUS.

     If an Event of Default (as defined in the Note Purchase Agreement) exists,
then the holders of Notes (as provided in and subject to Section 12 of the Note
Purchase Agreement) shall have the right to declare all of the Guaranteed
Obligations to be, and such Guaranteed Obligations shall thereupon become,
forthwith due and payable, without any presentment, demand, protest or other
notice of any kind, all of which have been expressly waived by the Company and
the Subsidiary Guarantors, and notwithstanding any stay, injunction or other
prohibition preventing such declaration (or such Guaranteed Obligations from
becoming automatically due and payable) as against the Company. In any such
event, the holders of Notes shall have immediate recourse to each of the
Subsidiary Guarantors to the fullest extent set forth herein.

     Notwithstanding any provision in this Guarantee or the Note Purchase
Agreement to the contrary, each Subsidiary Guarantor agrees that any
indebtedness of a Subsidiary Guarantor owing to the Company or another
Subsidiary Guarantor shall be subordinated in right of payment to the Guaranteed
Obligations of such Subsidiary Guarantor under this Guarantee owing to the
holders of Notes.

     2.16  TERMINATION.

     If the Company shall at any time be entitled to discharge any Subsidiary
Guarantor pursuant to the provisions of Section 10.13 of the Note Purchase
Agreement, and shall have delivered the notices to the holders of the Notes
required pursuant thereto, then such Subsidiary Guarantor shall be discharged
from this Guarantee.

3.   MISCELLANEOUS

     3.1   CERTAIN REPRESENTATIONS AND WARRANTIES.

     The Guarantor hereby confirms that each of the warranties and
representations contained in Section 5 of the Note Purchase Agreement is,
insofar as it refers to a Subsidiary specifically, or to the Subsidiaries
generally, true and correct with respect to the Guarantor. In addition to the
foregoing, the Guarantor represents and warrants that

<PAGE>
 
          (a)  this Guarantee has been duly authorized by all necessary
     corporate action on the part of the Guarantor and constitutes a legal,
     valid and binding obligation of the Guarantor, enforceable against it in
     accordance with its terms, except as such enforceability may be limited by
     (i) applicable bankruptcy, insolvency, reorganization, moratorium or other
     similar laws affecting the enforcement of creditors' rights generally and
     (ii) general principles of equity (regardless of whether such
     enforceability is considered in a proceeding in equity or at law) and
     public policy;

          (b)  the Guarantor has the corporate power and authority to execute
     and deliver this Guarantee and to perform the provisions hereof; and

          (c)  the execution, delivery and performance by the Guarantor of this
     Guarantee will not (i) contravene, result in any breach of, or constitute a
     default under, or result in the creation of any Lien in respect of any
     property of the Guarantor under, any Material indenture, mortgage, deed of
     trust, loan, purchase or credit agreement or lease, or the memorandum and
     articles of association, corporate charter or bylaws of the Guarantor, or
     any other Material agreement or instrument to which the Guarantor is party
     or by which such Guarantor or any of its properties may be bound or
     affected, (ii) conflict with or result in a breach of any of the terms,
     conditions or provisions of any order, judgment, decree, or ruling of any
     court, arbitrator or Governmental Authority applicable to the Guarantor or
     (iii) violate any provision of any statute or other rule or regulation of
     any Governmental Authority applicable to the Guarantor.

     3.2  NO WAIVER.

     No failure to exercise and no delay in exercising on the part of the
holders of Notes or any of them of any right, power or privilege under this
Guarantee shall operate as a waiver thereof, nor shall any single or partial
exercise of any right, power or privilege preclude any other or further exercise
thereof, or the exercise of any other right, power or privilege. No waiver by
the holders of Notes, or any of them, shall be effective unless it is in writing
and any such waiver shall affect only the rights of that party under this
Guarantee.

     3.3  GOVERNING LAW.

     THIS GUARANTEE SHALL BE CONSTRUED AND ENFORCED IN ACCORDANCE WITH, AND THE
RIGHTS OF THE PARTIES SHALL BE GOVERNED BY, THE LAW OF THE STATE OF NEW YORK,
EXCLUDING CHOICE-OF-LAW PRINCIPLES OF THE LAW OF SUCH STATE THAT WOULD REQUIRE
THE APPLICATION OF THE LAWS OF A JURISDICTION OTHER THAN SUCH STATE.

         Outstandings would exceed

<PAGE>
 
         $29,725,000, or the aggregate Taxable L/C Outstandings would exceed
         $61,500,000.

              (ii)  any order, judgment or decree of any Governmental
         Authority or arbitrator shall by its terms purport to enjoin or
         restrain the Agent from issuing such Letter of Credit, or any
         applicable law or any request or directive (whether or not having the
         force of law) from any Governmental Authority with jurisdiction over
         the Agent shall prohibit, or request that the Agent refrain from, the
         issuance of letters of credit generally or such Letter of Credit in
         particular;

              (iii) the Agent has received written notice from any Lender or
         the Company, on or prior to the Business Day prior to the requested
         date of issuance of such Letter of Credit, that one or more of the
         applicable conditions contained in Section 7 is not then satisfied;

         supporting any obligation other than the Issuer's obligations under the
         Bonds.

         SECTION 2.2     Issuance and Extension of Letters of Credit.
                         -------------------------------------------

         (a)  Each Letter of Credit shall be issued upon the irrevocable written
request of the Company received by the Agent at least one Business Day (or such
shorter time as the Agent may agree in a particular instance in its sole
discretion) prior to the proposed date of issuance. Each such request for
issuance of a Letter of Credit shall be by facsimile, confirmed promptly in an
original writing, in the form of an Application, and shall specify in form and
detail satisfactory to the Agent: (i) the face amount of the requested Letter of
Credit; (ii) the expiry date of such Letter of Credit; (iii) the name and
address of the beneficiary thereof; (iv) the documents to be presented by the
beneficiary of such Letter of Credit in case of any drawing thereunder; (v) the
full text of any certificate to be presented by the beneficiary in case of any
drawing thereunder; and (vi) such other matters as the Agent may require;
provided that the Credit Agreement shall prevail to the extent of any
- --------
inconsistency between the Credit Agreement and any Application.

         (b)  Unless the Agent has actual knowledge that, or has received notice
prior to issuing a requested Letter of Credit from any Lender that one or more
conditions specified in Section 7 are not then satisfied, then, subject to the
                        --------- 
terms and conditions hereof, the 

                                       3
<PAGE>
 
Agent, on the requested date, shall issue a Letter of Credit for the account of
the Company in accordance with the Agent's usual and customary business
practices therefor.

         (c) The Agent and the Lenders agree that, upon extension of the L/C
Commitment Termination Date in accordance with Section 2.11, the Agent shall
                                               ------------
extend the expiry date of any Letter of Credit issued by it for a period equal
to the shorter of (i) one year from the then current expiry date and (ii) the
period ending on the L/C Commitment Termination Date (after giving effect to
such extension). Notwithstanding the foregoing, in no event shall any Letter of
Credit be renewed such that its revised expiry date would extend beyond the
Stated Maturity Date.

         (d) The Agent may, at its election (or shall at the direction of the
Required Lenders), deliver any notices of termination or other communications to
any Letter of Credit beneficiary or transferee, and take any other action as
necessary or appropriate, at any time and from time to time, in order to cause
the expiry date of such Letter of Credit to be a date not later than the L/C
Commitment Termination Date.

         SECTION 2.3     Risk Participations, Drawings and Reimbursements.
                         ------------------------------------------------

         (a) Immediately upon the issuance of each Letter of Credit, each Lender
(other than the Agent) shall be deemed to, and hereby irrevocably and
unconditionally agrees to, purchase from the Agent a participation in such
Letter of Credit and each drawing thereunder in an amount equal to the product
of (i) the Percentage of such Lender, times (ii) the maximum amount available to
be drawn under such Letter of Credit and the amount of such drawing,
respectively.

         (b) In the event of any request for a drawing under a Letter of Credit
by the beneficiary or transferee thereof, the Agent will promptly notify the
Company. The Company shall reimburse the Agent prior to 10:00 a.m. (Chicago
time) on each date that any amount is paid by the Agent under any Letter of
Credit (each such date, an "Honor Date"), in an amount equal to the amount so
                            ----------
paid by the Agent. In the event the Company fails to reimburse the Agent for the
full amount of any drawing under any Letter of Credit by 10:00 a.m. (Chicago
time) on the Honor Date, the Agent will promptly notify each Lender thereof,
which notice shall be conclusive and binding on the Lenders. Any notice given by
the Agent pursuant to this Section 2.3(b) may be oral if immediately confirmed
                           --------------
in writing (including by facsimile); provided, that the lack of such an
                                     --------
immediate confirmation shall not affect the conclusiveness or binding effect of
such notice.

         (c) Each Lender (other than the Agent) shall upon any notice pursuant
to Section 2.3(b) make available to the Agent for its account an amount in
   --------------
Dollars and in immediately available funds equal to its Percentage of the amount
of the drawing. If any Lender so notified on or before 11:00 a.m. (Chicago time)
fails to make available to the Agent for its account the amount of such Lender's
Percentage of the amount of the drawing by no later 

                                       4
<PAGE>
 
than 1:00 p.m. (Chicago time) on the Honor Date (or if so notified after 11:00
a.m. (Chicago time) on or before 10:00 a.m. (Chicago time) on the next following
Business Day), then interest shall accrue on such Lender's obligation to make
such payment, from the Honor Date to the date such Lender makes such payment, at
a rate per annum equal to the Federal Funds Rate in effect from time to time
during such period. The Agent will promptly give notice of the occurrence of the
Honor Date, but failure of the Agent to give any such notice on the Honor Date
or in sufficient time to enable any Lender to effect such payment on such date
shall not relieve such Lender from its obligation to provide such Lender's
Percentage amount of such drawing under this Section 2.3.
                                             -----------

         (d) With respect to any drawing not reimbursed under Section 2.3(b) and
not constituting an L/C Loan under Section 2.7, the Reimbursement Obligation
(together with interest) shall be due and payable on demand and shall bear
interest at a rate per annum equal to the Past-Due Rate, and each Lender's
payment to the Agent pursuant to Section 2.3(c) shall be deemed payment in
                                 -------------
respect of its participation in such Reimbursement Obligation in satisfaction of
its participation obligation under this Section 2.3.
                                        -----------

         (e) Each Lender's obligation in accordance with this Agreement to make
the funds available to the Agent, as contemplated by this Section 2.3, as a
                                                          -----------
result of a drawing under a Letter of Credit, shall be absolute and
unconditional and without recourse to the Agent and shall not be affected by any
circumstance, including (i) any set-off, counterclaim, recoupment, defense or
other right which such Lender may have against the Agent, the Company or any
other Person for any reason whatsoever; (ii) the occurrence or continuance of a
Default, an Unmatured Default or an event which could reasonably be expected to
have a Material Adverse Effect; or (iii) any other circumstance, happening or
event whatsoever, whether or not similar to any of the foregoing.

         SECTION 2.4     Role of the Agent as Issuer.
                         ---------------------------

         (a) Each Lender and the Company agree that, in paying any drawing under
a Letter of Credit, the Agent shall not have any responsibility to obtain any
document (other than any sight draft and certificates expressly required by the
Letter of Credit) or to ascertain or inquire as to the validity or accuracy of
any such document or the authority of the Person executing or delivering any
such document.

         (b) The Agent shall, promptly following its receipt thereof, examine
all documents purporting to represent a demand for payment by the Trustee under
any Letter of Credit to ascertain that the same appear on their face to be in
conformity with the terms of and covered by such Letter of Credit. If, after
examination, the Agent shall have determined that a demand for payment under
such Letter of Credit does not conform to the terms and conditions of such
Letter of Credit, then the Agent shall, as soon as reasonably practicable, give
notice to the Trustee to the effect that negotiation was not in accordance with
the terms and conditions of the Letter of Credit, stating the reasons therefor
and that 

                                       5
<PAGE>
 
the relevant documents are being held at the disposal of the Trustee or are
being returned to the Trustee, as the Agent may elect. The Trustee may attempt
to correct any such nonconforming demand for payment under such Letter of Credit
if, and to the extent that, the Trustee is entitled (without regard to the
provisions of this sentence) and able to do so. If the Agent determines that a
demand for payment under such Letter of Credit conforms to the terms and
conditions of such Letter of Credit, then the Agent shall make payment to the
Trustee in accordance with the terms of such Letter of Credit. The Agent shall
have the right, provided it is not then in default under such Letter of Credit
by reason of its having wrongfully failed to honor a demand for payment
previously made by the Trustee under such Letter of Credit, to require the
Trustee to surrender such Letter of Credit to the Agent on the L/C Commitment
Termination Date after honoring any draws rightfully made by the Trustee under
such Letter of Credit on that date. The Company agrees, if necessary, to use its
best efforts to cause the Trustee so to surrender such Letter of Credit.

         (c) No Agent-Related Person nor any of the respective correspondents,
participants or assignees of the Agent shall be liable to any Lender for: (i)
any action taken or omitted in connection herewith at the request or with the
approval of all of the Lenders or the Required Lenders, as applicable; (ii) any
action taken or omitted in the absence of gross negligence or willful
misconduct; or (iii) the due execution, effectiveness, validity or
enforceability of any L/C-Related Document.

         (d) The Company hereby assumes all risks of the acts or omissions of
any beneficiary or transferee with respect to its use of any Letter of Credit;
provided, that such assumption is not intended to, and shall not, preclude the
- --------
Company's pursuing such rights and remedies as it may have against the
beneficiary or transferee at law or under any other agreement. No Agent-Related
Person, nor any of the respective correspondents, participants or assignees of
the Agent, shall be liable or responsible for any of the matters described in
clauses (i) through (vii) of Section 2.5; provided, anything in such clauses to
- ----------           ---     -----------  -------- 
the contrary notwithstanding, that the Company may have a claim against the
Agent, and the Agent may be liable to the Company, to the extent, but only to
the extent, of any direct, as opposed to consequential or exemplary, damages
suffered by the Company which the Company proves were caused by the Agent's
willful misconduct or gross negligence or the Agent's willful failure to pay
under any Letter of Credit after the presentation to it by the beneficiary of a
sight draft and certificate(s) strictly complying with the terms and conditions
of a Letter of Credit. In furtherance and not in limitation of the foregoing:
(i) the Agent may accept documents that appear on their face to be in order,
without responsibility for further investigation, regardless of any notice or
information to the contrary; and (ii) the Agent shall not be responsible for the
validity or sufficiency of any instrument transferring or assigning or
purporting to transfer or assign a Letter of Credit or the rights or benefits
thereunder or proceeds thereof, in whole or in part, which may prove to be
invalid or ineffective for any reason.

         SECTION 2.5     Obligations Absolute. The obligations of the Company

         any consent to departure from all or any of the L/C-Related Documents;

         that the Company may have at any time against any beneficiary or any
         transferee of any Letter of Credit (or any Person for whom any such
         beneficiary or any such transferee may be acting), the Agent or any
         other Person, whether in connection with this Agreement, the
         transactions contemplated hereby or by the L/C-Related Documents or any
         unrelated transaction;

              (iv)  any draft, demand, certificate or other document presented
         under any Letter of Credit proving to be forged, fraudulent, invalid or
         insufficient in any respect or any statement therein being untrue or
         inaccurate in any respect; or any loss or delay in the transmission or
         otherwise of any document required in order to make a drawing under any
         Letter of Credit;

              (v)   any payment by the Agent under any Letter of Credit against
         presentation of a draft or certificate that does not strictly comply
         with the terms of any Letter of Credit; or any payment made by the
         Agent under any Letter of Credit to any Person purporting to be a
         trustee in bankruptcy, debtor-in-possession, assignee for the benefit
         of creditors, liquidator, receiver or other representative of or
         successor to any beneficiary or any transferee of any Letter of Credit,
         including any arising in connection with any Insolvency Proceeding,
         unless such payment in on the part of the Agent;

              (vi)  any exchange, release or non-perfection of any
         collateral, or any release or amendment or waiver of or consent to
         departure from any other guarantee, for all or any of the obligations
         of the Company in respect of any Letter of Credit; or

                                       7
<PAGE>
 
              (vii) any other circumstance or happening whatsoever, whether
         or not similar to any of the foregoing, including any other
         circumstance that might otherwise constitute a defense available to, or
         a discharge of, the Company or a guarantor.

         SECTION 2.6     Uniform Customs and Practice. Except as otherwise
                         ----------------------------
expressly provided therein the Uniform Customs and Practice for Documentary
Credits as published by the International Chamber of Commerce most recently at
the time of issuance of any Letter of Credit shall apply to such Letter of
Credit.

         SECTION 2.7     L/C Loans. If the Agent shall make any payment under
                         ---------
any Letter of Credit pursuant to a Tender Draft and the conditions precedent in
Section 7.3 shall have been fulfilled, such payment shall constitute an advance
- -----------
made by the Lenders to the Company on the date and in the amount of such
payment, each such advance being an "L/C Loan". The Company shall repay the
                                     --------
unpaid principal amount of each L/C Loan on or before the earlier of (i) the
Stated Maturity Date or (ii) on the same date on which the Bonds, with respect
to which payment against such Tender Draft was made, are sold as a result of a
remarketing (which payment shall be made in accordance with Section 2.10(b) with
                                                            ---------------

         SECTION 2.8     Interest Provisions.
                         -------------------

         (a)   Interest Rates. The Company will pay interest on the unpaid

         the LIBOR Rate for such Interest Period plus the Applicable Margin.
                                                 ----

Each LIBOR Loan shall bear interest from (and including) the first day of the

<PAGE>
 
not be paid in full when due (whether at stated maturity, by acceleration, by
mandatory prepayment or otherwise), for the period from (and including) the due
date thereof to (but excluding) the date the same is paid in full and (ii) in
addition (without duplication), during any period in which a Default shall have

         SECTION 2.9     Conversions or Continuations of L/C Loans. Subject to
                         -----------------------------------------

                                                              -----------
Notwithstanding the foregoing, and without limiting the rights and remedies of
any of the Lenders and the Agent under Section 10, in the event that any Default
                                       ----------
or Unmatured Default shall have occurred and be continuing, the Agent may (and
at the request of the Required Lenders shall) suspend the right of the Company

of such prepayment 

                                       9
<PAGE>
 
on the amount prepaid; provided, that no notice shall be required and no
                       --------
interest shall accrue with respect to any such borrowing which is prepaid by the
Company on the date on which such amount is drawn under any Letter of Credit;
and provided, further, that the Company shall not be entitled to prepay any
    --------  -------
LIBOR Loan (other than on the last day of the applicable Interest Period) unless
such prepayment (including, without limitation, any such payment made in
accordance with Section 2.10(b)) shall be accompanied by an additional payment,
                ---------------
in accordance with Section 5.3, of an amount sufficient to compensate the
                   -----------
Lenders for any loss (including loss of anticipated profits), cost or expense

         (y) the aggregate amount of accrued and unpaid interest on the L/C

         as applicable, of such Letter of Credit shall be applied by the Agent
         for the account of the Lenders in reimbursement of such drawings (and
         as prepayment of L/C Loans and Reimbursement Obligations resulting from
         such drawings in the manner described in Section 2.7); and the Company
                                                  -----------

         Letter of Credit in accordance with the terms hereof and of such Letter
         of Credit.

               (ii) Any L/C Loans outstanding on the L/C Commitment Termination
         Date shall be due and payable on the Stated Maturity Date provided no
         Default or Unmatured Default shall have occurred and be continuing.

         SECTION 2.11    Extension of the L/C Commitment Termination Date.
                         ------------------------------------------------
Unless the L/C Commitment Termination Date shall have theretofore occurred, the
Company may, not less than 120 days before the second anniversary of the Initial
Funding Date or 120 days before each anniversary thereafter, request in writing
(each such request being irrevocable and binding) that the Lenders extend the
then scheduled L/C Commitment Termination Date for an additional one-year period
of time; provided that, in no event may the L/C Commitment Termination Date be
         --------
extended beyond the Stated Maturity Date. No later than 30 days from the date on

<PAGE>
 
Company pursuant to the preceding sentence, the Agent shall notify the Company
in writing (with a copy of such notice to the Trustee) whether or not the
Lenders consent to such request. No extension of the then scheduled L/C
Commitment Termination Date shall occur without the express written consent of
each of the Lenders. The Company acknowledges and agrees that the granting of
any such consent shall be in the sole and absolute discretion of the Lenders,
and if the Agent on behalf of the Lenders shall not notify the Company of such
consent within 30 days from the date on which the Agent shall have received
notice from the Company pursuant to the first sentence of this Section 2.11, the
                                                               ------------

                                                          --------
event shall the aggregate principal amount of all W/C Loans exceed the amount of
the Aggregate W/C Commitments as in effect from time to time. Subject to the
terms of this Agreement, during such period the Company may borrow the amount of
the Aggregate W/C Commitments by means of ABR Loans and LIBOR Loans. Subject to
the terms of this Agreement, W/C Loans may be repaid or prepaid and reborrowed.

         SECTION 3.2     Borrowings. The Company shall give the Agent notice of

right at any time to reduce in whole or in part the aggregate unused amount of

                         -------------------
any W/C Loan to be made by it on the date specified therefor shall not relieve
such Lender or any other Lender of its obligation to make its W/C Loan on such

of any other Lender to make a W/C Loan to be made by such other Lender.

         SECTION 3.5     Repayment of Loans. The Company hereby promises to pay

full, at the following rates per annum:

               (i)  during each period such W/C Loan is an ABR Loan, the ABR

         the LIBOR Rate for such Interest Period plus the Applicable Margin.

Each LIBOR Loan shall bear interest from (and including) the first day of the
applicable Interest Period to (but excluding) the last day of such Interest
Period at the interest rate determined as applicable to such LIBOR Loan.
Promptly after the determination of any interest rate provided for in this
Section 3.6(a) or any change therein, the Agent shall give notice thereof to the
- --------------
Lenders to which such interest is payable and to the Company.

         (b)   Other Interest Provisions. Notwithstanding the foregoing

Agent for the account of each Lender interest at the applicable Past-Due Rate on
any principal of any W/C Loan made by such Lender and on any other amount
payable by the Company hereunder which shall not be paid in full when due

otherwise), for the period from (and including) the due date thereof to (but
excluding) the date the same is paid in full and (ii) in addition (without
duplication), during any period in which a Default shall have occurred and be
continuing, the Company hereby promises to pay to the Agent for the account of
each Lender interest on any principal of any W/C Loan made by such Lender and on
any other amount payable by the Company

                                       13
<PAGE>
 
hereunder at a rate per annum equal to 2% above the rates (including any
Applicable Margin) otherwise applicable hereunder to such principal and such
other amount, respectively. Accrued interest on each W/C Loan shall be payable
(i) in the case of an ABR Loan, quarterly on the last day of each March, June,
September and December, (ii) in the case of a LIBOR Loan, on the last day of
each Interest Period therefor and, if any such Interest Period is longer than
three months, at three-month intervals following the first day of such Interest
Period, (iii) in the case of any W/C Loan, upon the payment or prepayment
thereof (but only on the principal amount so paid or prepaid), and (iv) in the
case of any W/C Loan, upon the Conversion of such W/C Loan to a W/C Loan of the
other Type (but only on the principal amount so Converted), except that interest
                                                            ------

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

         (c)   Maximum Rate. Anything in this Agreement to the contrary
               -------------
notwithstanding, in the event that the interest rate chargeable on any of the
W/C Loans pursuant to the terms of this Agreement shall exceed the highest
lawful rate that may be charged under applicable law, the interest rate shall be
deemed to be equal to the highest lawful rate.

         SECTION 3.7     Conversions or Continuations of W/C Loans. Subject to
                         -----------------------------------------
Sections 4.5 and 5.3, the Company shall have the right to Convert W/C Loans of
- ------------     ---
one Type into W/C Loans of the other Type or to Continue LIBOR Loans, at any
time or from time to time; provided, that the Company shall give the Agent
                           --------
notice of each such Conversion or Continuation as provided in Section 4.6.
                                                              -----------
Notwithstanding the foregoing, and without limiting the rights and remedies of
any of the Lenders and the Agent under Section 10, in the event that any Default
                                       ----------
or Unmatured Default shall have occurred and be continuing, the Agent may (and
at the request of the Required Lenders shall) suspend the right of the Company

then scheduled W/C Commitment Termination Date for an additional one-year period
of time; provided that, in no event may the W/C Commitment Termination Date be
         --------
extended beyond the seventh anniversary of the Initial Funding Date. No later
than 30 days from the date on which the Agent shall have received notice from
the Company pursuant to the preceding sentence, the Agent shall notify the
Company in writing whether or not the Lenders consent to such request. No

sole and absolute discretion

                                       14

of the Lenders, and if the Agent on behalf of the Lenders shall not notify the
Company of such consent within 30 days from the date on which the Agent shall
have received notice from the Company pursuant to the first sentence of this
Section 3.8, the Lenders shall be deemed not to have consented to such request.

respect of which such payment is made (each such payment received by the Agent
after noon (Chicago time) on any date to be deemed for purposes of this Section
                                                                        -------

         (d) Except as otherwise provided in the definition of "Interest

Reimbursement Obligation incurred and each borrowing made in respect of L/C
Loans or W/C Loans from time to time hereunder, and each payment made on account
of the principal thereof, shall be recorded by the Agent and each Lender on its
books; provided, that neither the failure of the Agent nor any Lender to make
       --------
any such recordation nor any error in such recordation shall affect the
obligations of the Company to make a payment when due in respect of each such
Reimbursement Obligation and borrowing and other unpaid amounts owing under this
Agreement; provided, further, that in no event shall the failure by the Agent or
           --------  -------
any Lender to make any such recordation nor any error therein obligate the
Company to pay any amounts in excess of amounts otherwise payable hereunder; and
further provided that, in the event of any discrepancy between the books of the

the event that the Company fails to select the Type (if applicable) of Loan, or

and otherwise as provided in this Section 4.6), such Loan (if outstanding as a
                                  -----------

taken by the Agent, the records of the Agent shall govern absent manifest error.

                         ---------------
Booking Office selected by such Lender and may change its Booking Office from

the Agent and the Company, designate a Booking Office through which Loans will
be made by it and for whose account payments are to be made on its Loans.

         SECTION 4.8     Non-Receipt of Funds by the Agent. Unless the Company
                         ---------------------------------
or a Lender, as the case may be, notifies the Agent prior to the date on which
it is scheduled to make payment to the Agent of (a) in the case of a Lender, the
participation in a Letter of Credit or proceeds of a Loan, or (b) in the case of
the Company, a payment of principal, interest or fees to the Agent for the
account of the Lenders, that it does not intend to make such payment, the Agent
may assume that such payment has been made. The Agent may,

                                       18
<PAGE>
 
but shall not be obligated to, make the amount of such payment available to the
intended recipient in reliance upon such assumption. If such Lender or the
Company, as the case may be, has not in fact made such payment to the Agent, the
recipient of such payment shall, on demand by the Agent, repay to the Agent the
amount so made available together with interest thereon in respect of each day
during the period commencing on the date such amount was so made available by
the Agent until the date the Agent recovers such amount at a rate per annum
equal to (i) in the case of payment by a Lender, the Federal Funds Rate for such
day or (ii) in the case of payment by the Company, the interest rate applicable
to the relevant Loan or Reimbursement Obligation.

         SECTION 4.9     Setoff. In addition to, and without limitation of, any
                         ------
rights of the Lenders under applicable law, if the Company becomes insolvent,
however evidenced, or a Default occurs, any indebtedness from any Lender to the
Company (including all account balances, whether provisional or final and
whether or not collected or available) may, subject to Section 4.10, be offset
                                                       ------------
and applied toward the payment of the Secured Obligations owing to such Lender,
whether or not the Secured Obligations, or any part of them, shall then be due.

         SECTION 4.10    Ratable Payments. If any Lender, whether by setoff or
                         ----------------
otherwise, has payment made to it upon its Loans or Reimbursement Obligations
(other than payments received pursuant to Sections 5.1, or 5.3) in a greater
                                          ------------     ---
proportion than that received by any other Lender, such Lender agrees, promptly
upon demand, to purchase a portion of the Loans or Reimbursement Obligations
held by the other Lenders so that after such purchase each Lender will hold its
ratable proportion of Loans or Reimbursement Obligations. If any Lender, whether
in connection with setoff or amounts which might be subject to setoff or
otherwise, receives Collateral or other protection for its Secured Obligations
or such amounts which may be subject to setoff, such Lender agrees, promptly
upon demand, to take such action as may be necessary such that all Lenders share
in the benefits of such Collateral ratably in proportion to their Loans or
Reimbursement Obligations. In case any such payment is disturbed by legal
process, or otherwise, appropriate further adjustments shall be made.

quasi-Governmental Rule (whether or not having the force of law), or any
interpretation thereof, or the compliance of any Lender therewith,

         tax, duty, charge or withholding on or from payments due from the
         Company (excluding federal taxation of the overall net income of any

         assessment, insurance charge, special deposit or similar requirement
         against assets of, deposits with or for the account of, or credit
         extended by, any Lender or any applicable Booking Office (other than
         reserves and assessments taken into account in determining the interest
         rate applicable to LIBOR Loans), or

                  (iii) imposes any other condition the result of which is to
         increase the cost to any Lender or any applicable Booking Office of
         making, funding or maintaining loans or reduces any amount receivable
         by any Lender or any applicable Booking Office in connection with loans
         or letters of credit, or requires any Lender or any applicable Booking
         Office to make any payment calculated by reference to the amount of
         loans held, letters of credit issued or interest received by it, by an
         amount deemed material by such Lender,

then, within 15 days of demand by such Lender, the Company shall pay such Lender

                         ---------------------------------------
determines the amount of capital required or expected to be maintained by such

Lender is increased as a result of a Change, then, within 15 days of demand by
                                             ----
such Lender, the Company shall pay such Lender the amount necessary to

         SECTION 5.3     Availability of Types of Loans. If any Lender
                         ------------------------------
determines that maintenance of its LIBOR Loans at a suitable Booking Office
would violate any applicable Governmental Rule, whether or not having the force
of law, or if the Required Lenders determine that (a) deposits of a type and
maturity appropriate to match fund LIBOR Loans are not available or (b) the
interest rate applicable to a LIBOR Loan does not accurately reflect the cost of
making or maintaining such Loan, then the Agent shall suspend the availability
of LIBOR Loans and require any outstanding LIBOR Loans, at the option of the
Company, to be repaid or converted into ABR Loans, in each case subject to
Section 5.4.

                         -----------------------
occurs on a date which is not the last day of the applicable Interest Period,
whether because of acceleration, prepayment or otherwise, or if any Loan is not
made or Converted or Continued on the date specified by the Company for any
reason other than default by the Lenders, then the Company will indemnify each
Lender for any loss or cost incurred by it resulting therefrom, including,
without limitation, any loss or cost in liquidating or employing deposits
acquired to fund or maintain such Loan.

         SECTION 5.5     Taxes.
                         -----

         (a) All payments made by the Company under this Agreement to the Agent,
and the Lenders shall be made free and clear of, and without reduction or
withholding for or on account of, any future income, franchise, property,
excise, sales, stamp or other taxes, levies, imposts, duties, charges, fees,
deductions or withholdings, hereafter imposed, levied, collected, withheld or
assessed by any Governmental Authority of the United States or any political
subdivision thereof, excluding, in the case of the Agent, and each Lender, net
income and franchise taxes imposed on the Agent or such Lender, as the case may
be, by the jurisdiction under the laws of which the Agent or such Lender, as the
case may be, is organized or any political subdivision or taxing authority
thereof or therein, or by any jurisdiction in which the Agent or such Lender or
its Booking Office, as the case may be, is located or any political subdivision
or taxing authority thereof or therein (all such non-excluded taxes, levies,
imposts, deductions, charges or withholdings being hereinafter called "Taxes").
If any Taxes are required to be withheld from any amounts payable to the Agent
or any Lender hereunder the amounts so payable to the Agent or such Lender, as
the case may be, shall be increased to the extent necessary to yield (after
payment of all Taxes) to the Agent or such Lender, as the case may be, interest
or any such other amounts payable hereunder at the rates or in the amounts
specified in this Agreement. Each Lender will designate a different Booking
Office if such designation would avoid the need for, or, if unavoidable, reduce
the amount of, such increase and would not, in the sole 

                                       21
<PAGE>
 
opinion of such Lender, be disadvantageous to such Lender. Whenever any Taxes
are payable by the Company, as promptly as possible thereafter, the Company
shall send to the Agent for its own account or for the account of such Lender, a
certified copy of any original official receipt received by the Company showing
payment thereof. The Company shall indemnify the Agent, and the Lenders for any
incremental taxes, interest or penalizes that may become payable by the Agent or
any such Lender as a result of any failure by the Company to pay any Taxes when
due to the appropriate taxing authority or to remit to the Agent the required
receipts or other required documentary evidence.

         (b) Upon becoming a party to this Agreement, each Lender that is not
incorporated under the laws of the United States, or a state thereof, agrees
that it will deliver to the Agent two duly completed copies of United States
Internal Revenue Service Form 1001 or 4224 (or applicable successor form),
certifying in either case that such Lender is entitled to receive payments under
this Agreement and its Notes without deduction or withholding, to the extent
provided for in such forms, of any United States federal income taxes. Each
Lender which so delivers a Form 1001 or 4224 (or applicable successor form)
further undertakes to deliver to the Agent two additional copies of each such
form on or before the date that such form expires or becomes obsolete or after
the occurrence of any event requiring a change in the most recent forms so
delivered by it, and such amendments thereto or extensions or renewals thereof
as may be reasonably requested by the Agent, in each case certifying in the case
of a Form 1001 or 4224 (or applicable successor form) that such Lender is
entitled to receive payments under this Agreement without deduction or
withholding of any United States federal income taxes, unless an event
(including any change in treaty, law or regulation) has occurred prior to the
date on which any such delivery would otherwise be required which renders all
such forms inapplicable or which would prevent such Lender from duly completing
and delivering any such form with respect to it and such Lender advises the
Company and the Agent that it is not capable of receiving payments without any
deduction or withholding of United States federal income tax such Loan.

         SECTION 5.6     Lender Statements; Survival of Indemnity. To the extent
                         ----------------------------------------
reasonably possible, each Lender shall designate an alternate Booking Office
with respect to its LIBOR Loans to reduce any liability of the Company to such
Lender under Sections 5.1 and 5.3 or to avoid the unavailability of LIBOR Loans
             ------------     ---
under Section 5.3, so long as such designation is not disadvantageous to such
      -----------
Lender in its sole determination. Each Lender shall deliver a written statement
of such Lender to the Company (with a copy to the Agent) as to the amount due,
if any, under Section 5.1, 5.2, 5.4 or 5.5. Such written statement shall set
              -----------  ---  ---    ---
forth in reasonable detail the calculations upon which such Lender determined
such amount and shall be final, conclusive and binding on the Company in the
absence of manifest error. Determination of amounts payable under such Sections
in connection with a LIBOR Loan shall be calculated as though each Lender funded
its LIBOR Loan through the purchase of a deposit of the type and maturity
corresponding to the deposit used as a reference in determining the LIBOR Rate
applicable to such LIBOR 

                                       22
<PAGE>
 
Loan, whether in fact that is the case or not. Unless otherwise provided herein,
the amount specified in the written statement of any Lender shall be payable
within 15 days of receipt by the Company of such written statement. The
obligations of the Company under Sections 5.1, 5.2, 5.4 and 5.5 shall survive
                                 ------------  ---  ---     ---
payment or prepayment of the Credit Obligations and the termination of the
Credit Agreement.

     the Collateral, except for any such agreement with the Agent, until the

          Collateral, has not registered any security interest in the Collateral
          and has not entered into any agreement with any other party to comply

parties to such Assigned Agreement in default.  The Agent shall have a
reasonable opportunity to cure such default.  Any cure by the Agent of the
Company's default under any Assigned Agreement shall not be construed as an
assumption by the Agent of any obligations, covenants or agreements of the
Company under such Assigned Agreement, and the Agent shall not incur any
liability to the Company or any other Person as a result of any actions
undertaken by the Agent or in curing or attempting to cure any such default.
This Agreement shall not be deemed to release or to affect in any way the
obligations of the Company under the Assigned Agreements.

                  ------------------                                    
hereunder shall not impose any duty upon it to exercise any such powers.  Except
for the safe custody of any Collateral in its possession and the accounting for
moneys actually received by it hereunder, the Agent shall have no duty as to any
Collateral or as to the taking of any necessary steps to preserve any rights
pertaining to any Collateral.

     SECTION 19.  Rights and Remedies.  (a)  All payments received by the
                  -------------------

received in trust to the extent of the Secured Obligations for the benefit of
the Secured Parties, and shall be deposited in the same form as so received
(with any necessary endorsement) in the Accounts as provided in this Agreement.

     (b)  If a Default shall have occurred, all payments made under or in
connection with the Assigned Agreements or in respect of the other Collateral
and held by the Agent in the Collateral Account in accordance with the
provisions of this Agreement may, subject to the provisions of this Agreement,
at any time thereafter be applied as follows:

          First, to the payment of (A) all costs and expenses relating to the
          -----                                                              
     sale or other disposition of the Collateral or any part thereof and
     collection of amounts owing hereunder, including reasonable attorneys' fees
     and disbursements and the just compensation of the Agent for services
     rendered in connection therewith or in connection with any proceeding to
     sell if a sale is not completed, and (B) all reasonable charges, expenses
     and advances incurred or made by the Agent in order to protect the lien and
     security interest of this Agreement or the security afforded hereby,
     together with interest accrued thereon at a rate per annum equal to the sum
     of the ABR Rate plus 2%;

          Second, to the payment of accrued interest on the Loans in such manner
          ------                                                                
     as the Agent shall direct so that each of the Lenders shall have an
     equivalent number of days with respect to which interest on the Loans shall
     have accrued and be unpaid;

          Third, to the payment in full of accrued interest on the Loans (to be
          -----                                                                
     paid to the Lenders pro rata in accordance with the respective unpaid
     amounts of interest owed to them);

          Fourth, to cash collateralize the Letters of Credit;
          ------                                              

          Fifth, pro rata to the payment of:
          -----                             

               (i)  unpaid principal of the Loans then due and owing,

               (ii) the Termination Amount then due and owing with respect to
          the aggregate amount payable as a result of termination of the Hedge
          Agreements

          (payments under clause (i) to be made pro rata among the Lenders in
          accordance with the amounts of principal owed to them, and payments
          under clause (ii) to be made pro rata among the Hedge Counterparties);

          For purposes of this paragraph Fifth, "Termination Amount" shall mean
                                                 ------------------            
          an amount equal to the aggregate amount payable as a result of
          termination of Hedge Agreements in connection with the Loans being
          repaid under this paragraph Fifth or the cash collateralization of the
          Letters of Credit under paragraph Fourth;

                                     -13-
<PAGE>
 
          Sixth, to the payment of all other Secured Obligations then due and
          -----                                                              
     owing to the Secured Parties (to be paid to the Secured Parties pro rata in
     accordance with the respective aggregate outstanding amounts of such other
     Secured Obligations owed to them); and
 
          Seventh, provided all Secured Obligations owed (whether or not then
          -------                                                            
     due) to the Secured Parties have been paid in full, the balance, if any,
     shall be paid to such other Person as shall be lawfully entitled to receive
     any thereof, and finally, to the Company.

     (c)  If a Default shall have occurred, then, in addition to any other
rights and remedies provided for herein or which may otherwise be available, the
Agent shall, upon the direction of the Required Lenders, without any further
demand, advertisement or notice (except as expressly provided for below in this
                                 ------
Section 19(c) or as required by applicable law), exercise all the rights and
- -------------                                         
remedies of a secured party under the UCC (whether or not the UCC applies to the
affected Collateral), and in addition may sell or otherwise dispose of the
Collateral, or any part thereof, as hereinafter provided. In connection
therewith, the Collateral may be sold in one or more sales, at public or private
sale, conducted by any officer or agent of, or auctioneer or attorney for, the
Agent, at the Agent's place of business or elsewhere, for cash, upon credit or
for other property, for immediate or future delivery, on such terms as the Agent
shall deem appropriate and at such price or prices as the Agent shall deem best.
The Agent and any other Secured Party may be the purchaser of any or all of the
Collateral so sold at a public sale, and the obligations of the Company to any
such purchaser may be applied as a credit against the purchase price. The Agent
may, in its sole discretion, at any such sale, restrict the prospective bidders
or purchasers as to the nature of their business, their experience and ability
with respect to the operation of medium density fiberboard plants similar to the
Facility and their ownership structure. Upon any such sale, the Agent shall have
the right to deliver, assign and transfer to the purchaser thereof the
Collateral so sold. Each purchaser (including the Agent and any other Secured
Party) at any such sale shall hold the Collateral so sold absolutely free from
any claim or right of the Company of whatsoever kind, including any equity or
right of redemption, and the Company hereby specifically waives, to the full
extent it may lawfully do so, all rights of redemption, stay or appraisal now
existing or hereafter adopted. The Agent shall give the Company at least 10
days' notice (which the Company agrees is reasonable notification within the
meaning of Section 9-504(3) of the UCC) of any such public or private sale. Such
notice, in case of public sale, shall state the time and place fixed for such
sale. Any such public sale shall be held at such time or times within ordinary
business hours as the Agent shall fix in the notice of such sale. At any such
sale, the Collateral may be sold in one lot as an entirety or in separate
parcels. The Agent shall not be obligated to make any sale pursuant to any such
notice. The Agent may, without notice or publication, adjourn any public or
private sale or cause the same to be adjourned from time to time by announcement
at the time and place fixed for such sale, and any such sale may be made at any
time or place to which the same may be so adjourned without further notice or
publication. In case of any sale of all or any part of the Collateral on credit
or for future delivery, the Collateral so sold may be retained by the Agent
until the full selling price is paid by the purchaser thereof, but the Agent
shall not incur any liability in case of the failure of such purchaser to take
up and

                                     -14-
<PAGE>
 
pay for the Collateral so sold, and, in case of any such failure, such
Collateral may again be sold pursuant to the provisions hereof.

     (d)  If a Default shall have occurred, instead of exercising the power of
sale provided in Section 19(c), the Agent shall, upon the direction of the
                 -------------                                            
Required Lenders, proceed by a suit or suits at law or in equity to foreclose
the pledge and security interest under this Agreement and sell the Collateral or
any portion thereof under a judgment or decree of a court or courts of competent
jurisdiction.

     (e)  If a Default shall have occurred, the Agent, as attorney-in-fact
pursuant to Section 16, may, in the name and stead of the Company, make and
            ----------                                                     
execute all conveyances, assignments and transfers of the Collateral sold
pursuant to Section 19(c), and the Company hereby ratifies and confirms all that
            -------------                                                       
the Agent, as said attorney-in-fact, shall do by virtue hereof. Nevertheless,
the Company shall, if so requested by the Agent, ratify and confirm any sale or
sales by executing and delivering to the Agent, or to such purchaser or
purchasers, all such instruments as may, in the judgment of the Agent, be
advisable for the purpose.

     (f)  The receipt of the Agent for the purchase money paid at any sale made
by it pursuant to Section 19(c) shall be a sufficient discharge to any purchaser
                  -------------                                                 
for the purchase price of the Collateral, or any portion thereof, sold as
aforesaid; and no such purchaser (or the representatives or assigns of such
purchaser), after paying such purchase money and receiving such receipt, shall
be bound to see to the application of such purchase money, or any part thereof,
or in any manner whatsoever be answerable for any loss, misapplication or
nonapplication of any such purchase money, or any part thereof, or be bound to
inquire as to the authorization, necessity, expediency or regularity of such
sale.

     (g)  The Agent shall not incur any liability as a result of the manner of
sale of the Collateral, or any part thereof, at any private sale conducted in a
commercially reasonable manner. The Company hereby waives, to the full extent
permitted by applicable law, any claims against the Agent or the Secured Parties
arising by reason of the fact that the price at which the Collateral, or any
part thereof, may have been sold at a private sale was less than the price which
might have been obtained at a public sale or was less than the aggregate amount
of the Secured Obligations, even if the Agent accepts the first offer received,
which the Agent in good faith deems to be commercially reasonable under the
circumstances and does not offer the Collateral to more than one offeree.  To
the extent permitted by law, the Company shall have the burden of proving that
any such sale of the Collateral was conducted in a commercially unreasonable
manner.

     (h)  Each and every right and remedy of the Agent shall, to the extent
permitted by law, be cumulative and shall be in addition to any other remedy
given hereunder or under the Credit Agreement or any other Project Document or
now or hereafter existing at law or in equity or by statute.

resulting from the gross negligence, bad faith or willful misconduct of such
Person) or (ii) any refund or adjustment (other than any refund or adjustment
ordered or required as a result of the gross negligence, bad faith or willful
misconduct of any Secured Party) of any amount paid or payable to the Agent
under or in respect of any of the Assigned Agreements, or any interest thereon,
which may be ordered or otherwise required by any Person.

     (b)  The Company shall, upon demand, pay to the Agent the amount of any and
all reasonable expenses (together with interest thereon at a rate per annum
equal to the sum of the ABR Rate plus 2%), including the reasonable fees and
expenses of counsel and of any experts and agents, which the Agent may incur
following the occurrence and during the continuance of a Default in connection
with (i) the administration of this Agreement, (ii) the custody or preservation
of, or the collection from or other realization upon, any of the Collateral,
(iii) the exercise or enforcement of any of the rights of the Agent hereunder or
(iv) the failure by the Company to perform or observe any of the provisions
hereof.

     (c)  In any suit, proceeding or action brought by the Agent or any Secured
Party under any Assigned Agreement or for any sum owing thereunder, or to
enforce any provisions of such Assigned Agreement, the Company will save,
indemnify, and hold the Agent and the Secured Parties harmless from and against
any and all expenses, losses or damages suffered by reason of any defense, set-
off, counterclaim, recoupment or reduction of liability whatsoever of the other
party under such Assigned Agreement arising out of a breach by the Company of
any obligation to the other party under such Assigned Agreement or arising out
of any other agreement, indebtedness or liability at any time owing to or in
favor of such other party or successors from the Company, and all such
obligations of the Company shall be and remain enforceable against and only
against the Company and shall not be enforceable against the Agent or the
Secured Parties.

     SECTION 21.  Amendments; etc.  No amendment, modification or waiver of any
                  ----------------                                             
provision of this Agreement nor consent to any departure by the Company herefrom
shall in any event be effective unless the same shall be in writing and signed

and for the specific purpose for which given.

     SECTION 23.  Continuing Assignment and Security Interest.  (a)  This
                  -------------------------------------------            
Agreement shall create a continuing assignment of and security interest in the
Collateral and shall (i) remain in full force and effect until termination of
all of the Commitments and payment in full of the Secured Obligations, (ii) be
binding upon the Company, its successors and assigns and (iii) inure, together
with the rights and remedies of the Agent hereunder, to the equal and ratable

interest granted hereby shall terminate, and all rights to the Collateral shall,
subject to any other security interest applicable thereto, revert to the
Company.  Upon any such termination, the Agent will, at the Company's expense,
execute and deliver to the Company such documents as the Company shall

sale by the Company of any portion of the Collateral permitted by Section 9.10

reasonably request to evidence such termination.

     (c)  As used in Section 23(b), the term "Termination Date" shall mean the

occurrence of a Default, the Company shall, at the request of the Agent, assign,
transfer or otherwise furnish to the Agent (to the extent so assignable or
transferable) or to any transferee of the interest of the Agent, all of the
Company's rights and interest in, to and under all Permits, offsets and similar
rights issued under or in connection with any Environmental Law, including
Permits respecting air emissions (including air emission reduction credits or
offsets), wastewater discharge, and solid or hazardous waste management, which
are required or advisable from time to time to permit the Project to be operated
in accordance with all applicable laws.  The Company agrees to use its best
efforts to have renewed or extended in the name of the Agent (or other Person
operating the Project) or otherwise to obtain for the Agent (or such other
Person) the benefits of all of the Permits and other rights referred to in the
immediately preceding sentence.

to, the Mortgagee as follows:

                                      -6-
<PAGE>
 
     1.   Payment of Liabilities.  The Mortgagor agrees that it will pay, timely
          ----------------------                                                
and in the manner required in the appropriate documents or instruments, the
principal of and interest on the Loans (which Loans, pursuant to the terms of
the Credit Agreement as in effect on the date hereof, are required to be repaid
in full no later than the earlier of (a) the seventh anniversary of the Initial

Agreement, the Mortgagor will pay, before delinquent, all taxes and assessments,
general or special, and any and all levies, claims, charges, expenses and liens,
ordinary or extraordinary, governmental or non-governmental, statutory or
otherwise, due or to become delinquent, that may be levied, assessed, made,
imposed or charged on or against the Collateral or any property used in
connection therewith, and will pay before due any tax or other charge on the
interest or estate in lands created or represented by this Mortgage or by any of
the other Credit Documents, whether levied against the Mortgagor or the
Mortgagee or otherwise, and will submit to the Mortgagee upon request all
receipts showing payment of all of such taxes, assessments and charges.

     3.   Maintenance and Repair.  Except as permitted by the Credit Agreement,
          ----------------------

     4.   Sales; Liens.  Except as permitted by the Credit Agreement, the
          ------------                                                   
Mortgagor will not:  (i) sell, assign, transfer, convey, lease or otherwise
dispose of, or permit to be sold, assigned, transferred, conveyed, leased or
otherwise disposed of, the Collateral or any part thereof or any interest
(whether legal, beneficial or otherwise) or estate in any thereof; (ii) remove

any mortgage, lien, claim, security interest, charge, encumbrance or other right
or claim of any kind whatsoever upon the Collateral or any part thereof, except
those of current taxes not delinquent and the Permitted Liens; provided that the
                                                               --------         
Mortgagor may sell the Premises (subject to the Lien of this Mortgage) to the
County subject to the simultaneous execution 

                                      -7-
<PAGE>
 
and delivery of the Bond Lease; provided further that such sale to the County
                                -------- ------- 
shall not release the Mortgagor in any respect from its obligations hereunder.

     5.   Access by Mortgagee.  The Mortgagor will at all times permit the
          -------------------                                             
Mortgagee and its agents and designees, at all reasonable times, to enter on and
inspect the Premises.

     6.   Stamp and Other Taxes.  If the Federal, or any state, county, local,
          ---------------------                                               
municipal or other, government or any subdivision of any thereof having
jurisdiction, shall levy, assess or charge any tax (excepting therefrom any
income tax on the Mortgagee's receipt of interest payments on the principal
portion of the indebtedness secured hereby), assessment or imposition upon this
Mortgage, the Liabilities or any of the other Credit Documents, the interest of
the Mortgagee in the Collateral, or any of the foregoing, or upon the Mortgagee
by reason of or as holder of any of the foregoing, or shall at any time or times
require revenue stamps to be affixed to this Mortgage, or any of the other
Credit Documents, the Mortgagor shall pay all such taxes and stamps to or for
the Mortgagee as they become due and payable in accordance with the Credit
Agreement.  If any law or regulation is enacted or adopted permitting,
authorizing or requiring any such tax, assessment or imposition to be levied,
assessed or charged, which law or regulation prohibits the Mortgagor from paying
such tax, assessment, stamp, or imposition to or for the Mortgagee, then such
event shall constitute a Default hereunder and all sums hereby secured shall
become immediately due and payable at the option of the Mortgagee.

     7.   Insurance.  The Mortgagor will at all times maintain (or caused to be
          ---------                                                            
maintained) on the Goods, the Improvements and on all other Collateral, all
insurance required at any time or from time to time by the Mortgagee or by the
provisions of the Credit Agreement and the Bond Lease and in any event fire and
extended coverage insurance for the benefit of the Mortgagee, to the full extent
of the Mortgagee's interest therein, against loss or damage (whether to such
Collateral or Improvements or by loss of rentals, business interruption, loss of
occupancy or other damage therefrom) from such hazards as may be required by the
Mortgagee pursuant to the Credit Agreement.  The Mortgagor agrees that any loss
paid to the Mortgagee under any of such policies of property or casualty (but
not including business or rental interruption) insurance shall be applied in the
manner set forth in the Credit Agreement.

     8.   Eminent Domain.  In case the Collateral, or any part or interest in
          --------------                                                     
any thereof, is the subject of a Taking, all condemnation awards or other
compensation paid as a result thereof (all of which the Mortgagor hereby assigns
to the Mortgagee), shall be forthwith applied in the manner set forth in the
Credit Agreement.

     9.   Governmental Requirements.  The Mortgagor will at all times fully
          -------------------------                                        
comply in all material respects with, and cause the Collateral and the use and
condition thereof fully to comply with, all federal, state, county, municipal,
local and other governmental statutes, 

                                      -8-
<PAGE>
 
ordinances, requirements, regulations, rules, orders and decrees of any kind
whatsoever that apply or relate to the Mortgagor or the Collateral or the use
thereof, and will observe and comply with all conditions and requirements
necessary to preserve and extend any and all rights, licenses, permits,
privileges, franchises and concessions (including, without limitation, those
relating to land use and development, landmark preservation, construction,
access, water rights and use, noise and pollution) which are applicable to the
Mortgagor or have been granted for the Collateral or the use thereof, all in
accordance with the Credit Agreement.

     10.  No Mechanics' Liens.  The Mortgagor will use its best efforts not to
          -------------------                                                 
do or permit to be done any act or thing whereby any mechanics' lien under the
laws of the State of Arkansas can arise against or attach to the Premises or any
part thereof unless such lien shall first be wholly waived as against this
Mortgage; provided that, if any such lien should be filed the Mortgagor will use
          --------                                                              
its best efforts to have any such lien removed within 21 days after the date the
Mortgagor learns of such lien.  In addition, it is further expressly made a
covenant and condition hereof that the lien of this Mortgage shall extend to any
and all improvements and fixtures now or hereafter on the Premises, prior to any
other lien thereon that may be claimed by any person, so that subsequently
accruing claims for lien on the Premises shall be junior and subordinate to this
Mortgage.  TO THE EXTENT PROVIDED BY LAW, ALL CONTRACTORS, SUBCONTRACTORS, AND
OTHER PARTIES DEALING WITH THE PREMISES, OR WITH ANY PARTIES INTERESTED THEREIN,
ARE HEREBY REQUIRED TO TAKE NOTICE OF THE ABOVE PROVISIONS.

     11.  Continuing Priority.  The Mortgagor will: (i) pay such fees, taxes and
          -------------------                                                   
charges, execute and file (at the Mortgagor's expense) such financing
statements, obtain such acknowledgments or consents, notify such obligors or
providers of services and materials and do all such other acts and things as the
Mortgagee may from time to time request to establish and maintain a valid and
perfected first and prior lien on and security interest in the Collateral and to
provide for payment to the Mortgagee directly of all cash proceeds thereof, with
the Mortgagee in possession of the Collateral to the extent it requests; (ii)
maintain its executive office and principal place of business at all times at
the address shown above; (iii) keep all of its books and records relating to the
Collateral on the Premises or at such address; (iv) keep all tangible Collateral
on the Real Estate except as the Mortgagee may otherwise consent in writing; (v)
make notations on its books and records sufficient to enable the Mortgagee, as
well as third parties, to determine the interest of the Mortgagee hereunder; and
(vi) not collect any rents or the proceeds of any of the Leases or Intangibles
more than 30 days before the same shall be due and payable except as the
Mortgagee may otherwise consent in writing, all in accordance with the Credit
Documents.

     12.  Utilities.  The Mortgagor will pay all utility charges incurred in
          ---------                                                         
connection with the Collateral and maintain all utility services available for
use at the Premises.

                                      -9-
<PAGE>
 
     13.  Contract Maintenance; Other Agreements.  The Mortgagor will, in
          --------------------------------------                         
accordance with the Credit Agreement, for the benefit of the Mortgagee, fully
and promptly perform each obligation and satisfy each condition imposed on it
under the Bond Lease, any Contract for Sale, Contract for Construction, Project
Contract, Lease, Intangible or other agreement so that there will be no default
thereunder and so that the persons (other than the Mortgagor) obligated thereon
shall be and remain at all times obligated to perform for the benefit of the
Mortgagee; and the Mortgagor will not permit to exist any condition, event or
fact which could allow or serve as a basis or justification for any such person
to avoid such performance.

     14.  Agreements Affecting the Collateral.  The Mortgagor shall keep,
          -----------------------------------                            
observe, perform and comply with all covenants, conditions and restrictions
affecting the Premises, any operating agreements or other writings relating to
the Collateral, and all leases, instruments and documents relating thereto or
evidencing or securing any indebtedness secured thereby, all in accordance with
the Credit Agreement.

     15.  No Assignments; Future Leases; Assignment of Rents.  Except as
          --------------------------------------------------            
permitted by the Credit Agreement, the Mortgagor will not cause or permit any
Rents, issues, profits, the Bond Lease, Leases, Contracts for Sale, or other
contracts relating to the Premises, or any interest in any thereof, to be
assigned, transferred, conveyed, pledged or disposed of, to any party other than
the Mortgagee without first obtaining the express written consent of the
Mortgagee thereto which consent may be granted or withheld in the sole
discretion of the Mortgagee.  In addition, the Mortgagor shall not cause or
permit all or any portion of or interest in the Premises or the Improvements to
be leased (that word having the same meaning for purposes hereof as it does in
the law of landlord and tenant) directly or indirectly to any person, except
with the prior written consent of the Mortgagee, which consent may be granted or
withheld in the sole discretion of the Mortgagee.

     The Mortgagor does hereby grant, bargain, sell, assign, transfer and set
over to the Mortgagee, all of the rents, income, proceeds and benefits under the
Leases; provided, however, that permission is hereby given to the Mortgagor,
unless a Default has occurred and is continuing and the Mortgagee has given
notice to the Mortgagor, to collect, receive, and apply the Rents, proceeds
thereof and other rents, income, proceeds and benefits as they become due and
payable, but not in advance thereof, and in accordance with all of the other
terms, conditions and provisions hereof, the Credit Documents and of the Leases,
contracts, agreements and other instruments with respect to which such payments
are made or such other benefits are conferred.  Upon the occurrence of and
during the continuance of a Default, such permission shall terminate immediately
upon notice from the Mortgagee, and once so terminated shall not be reinstated
upon a cure of such Default without the express written consent of the
Mortgagee.  Such assignment shall be fully effective without any further action
on the part of the Mortgagor or the Mortgagee and the Mortgagee shall be
entitled, in accordance with the Credit Documents, upon the occurrence of and
during the continuance of a Default hereunder, upon notice to the 

                                     -10-
<PAGE>
 
Mortgagor, to collect, receive and apply all Rents, Proceeds and all other
rents, income, proceeds and benefits from the Collateral, including all right,
title and interest of the Mortgagor in any escrowed sums or deposits or any
portion thereof or interest therein, whether or not the Mortgagee takes
possession of the Collateral or any part thereof.

     16.  Collections.  Until such time as the Mortgagee shall notify the
          -----------                                                    
Mortgagor of the revocation of such power and authority, the Mortgagor will, at
its own expense, endeavor to collect, as and when due, all amounts due with
respect to any of the Rents, Leases, Contracts for Sale, Intangibles and other
Collateral, including the taking of such action with respect to such collection
as the Mortgagee may reasonably request, or, in the absence of such request, as
the Mortgagor may deem advisable.  The Mortgagee, however, may, at any time,
whether before or after any Default or any revocation of such power and
authority or the maturity of any of the Liabilities, notify any parties
obligated on any of the Rents, Leases, Contracts for Sale, Intangibles and other
Collateral to make payment to the Mortgagee of any amounts due or to become due
thereunder and enforce collection of any of the Rents, Leases, Contract for
Sale, Intangibles or other Collateral by suit or otherwise and surrender,
release or exchange all or any part thereof, or compromise or extend or renew
for any period (whether or not longer than the original period) any indebtedness
thereunder or evidenced thereby.  Upon request of the Mortgagee, the Mortgagor
will, in accordance with the Credit Documents, at its own expense, notify any
parties obligated on any of the Rents, Leases, Contracts for Sale, Intangibles
or other Collateral to make payment to the Mortgagee of the amounts due or to
become due thereunder.  Except as the Mortgagee may otherwise consent in
writing, the Mortgagor will, in accordance with the Credit Documents, forthwith,
upon receipt, transmit and deliver to the Mortgagee, in the form received, all
cash, checks, drafts, chattel paper and other instruments or writings for the
payment of money (properly endorsed, where required, so that such items may be
collected by the Mortgagee) which may be received by the Mortgagor at any time
in full or partial payment or otherwise as proceeds of any of the Collateral.
Any such items which may be received by the Mortgagor will not be commingled
with any other of its funds or property, but will be held separate and apart
from its own funds or property and upon express trust for the Mortgagee until
delivery is made to the Mortgagee. The Mortgagee is authorized to endorse, in
the name of the Mortgagor, any item, howsoever received by it, representing any
payment on or other proceeds of any of the Collateral and to endorse and
deliver, in the name of the Mortgagor, any instrument, chattel paper or other
item of Collateral held by the Mortgagee hereunder, in connection with the sale
or collection of Collateral, in accordance with the Credit Documents.  The
Mortgagor hereby irrevocably appoints the Mortgagee as the Mortgagor's attorney-
in-fact to exercise and perform any or all of the foregoing rights and duties.

     17.  Mortgagee's Performance.  If the Mortgagor fails to pay or perform any
          -----------------------                                               
of its obligations herein contained (including payment of expenses of
foreclosure and court costs), the Mortgagee may (but need not), as agent or
attorney-in-fact of the Mortgagor, after giving the Mortgagor notice of its
intention to do so (no such notice need be given 

                                     -11-
<PAGE>
 
after the occurrence of a Default), make any payment or perform (or cause to be
performed) any obligation of the Mortgagor hereunder, in any form and manner
deemed expedient by the Mortgagee, and any amount so paid or expended (plus
reasonable compensation to the Mortgagee for its out-of-pocket and other
expenses for each matter for which it acts under this Mortgage), with interest
thereon at the rate applicable after maturity as provided in the Credit
Agreement, shall be added to the principal debt hereby secured and shall be
repaid to the Mortgagee upon demand. By way of illustration and not in
limitation of the foregoing, the Mortgagee may (but need not) do all or any of
the following: (i) make payments of principal or interest or other amounts on
any lien, encumbrance or charge on any of the Collateral; (ii) make payments
under the Bond Lease; (iii) complete construction; (iv) make repairs; (v)
collect rents; (vi) prosecute collection of the Collateral or proceeds thereof;
(vii) purchase, discharge, compromise or settle any tax lien or any other lien,
encumbrance, suit, proceeding, title or claim thereof; (viii) contest any tax or
assessment; and (ix) redeem from any tax sale or forfeiture affecting the
Premises. In making any payment or securing any performance relating to any
obligation of the Mortgagor hereunder, the Mortgagee shall (as long as it acts
in good faith) be the sole judge of the legality, validity and amount of any
lien or encumbrance and of all other matters necessary to be determined in
satisfaction thereof. No such action of the Mortgagee shall ever be considered
as a waiver of any right accruing to it on account of the occurrence of any
matter which constitutes a Default (defined hereinafter).

     18.  Subrogation.  To the extent that the Mortgagee, on or after the date
          -----------                                                         
hereof, pays any sum due under any provision of law or any instrument or
document creating any lien prior or superior to the lien of this Mortgage, or
the Mortgagor or any other person pays any such sum with the proceeds of the
Loan, the Mortgagee shall have and be entitled to a lien on the Collateral equal
in priority to the lien discharged, and the Mortgagee shall be subrogated to,
and receive and enjoy all rights and liens possessed, held or enjoyed by, the
holder of such lien, which shall remain in existence and benefit the Mortgagee
in securing the Liabilities.  Without limiting the generality of the foregoing,
and in addition thereto (rather than in limitation thereof), the Mortgagee shall
be subrogated to the liens of all other mortgages, trust deeds, superior titles,
vendors' liens, liens, charges, encumbrances, rights and equities on the
Premises, to the extent that either (i) any obligation under any thereof is paid
or discharged with proceeds of disbursements or advances under the Credit
Agreement or of other indebtedness secured hereby or (ii) the release thereof
was granted or delivered in complete or partial consideration for the granting
of this Mortgage.

     19.  Hazardous Materials.  The Mortgagor hereby reaffirms all
          -------------------                                     
representations, warranties and covenants made by the Mortgagor with respect to
environmental matters in the Credit Agreement.

     20.  Mortgagor's Right to Contest.  The Mortgagor may contest or object to
          ----------------------------                                         
the legal validity or amount of any tax in accordance with the Credit Agreement
or any 

                                     -12-
<PAGE>
 
mechanics' or materialmen's lien on the Premises on and subject to the following
conditions: (i) After having given the Mortgagee at least five business days'
prior written notice of its intention to institute such proceedings, the
Mortgagor shall in good faith have instituted appropriate legal proceedings with
respect thereto, the pendency of which shall have the legal effect of staying
the effectiveness and enforcement of such taxes or lien (as the case may be) and
any and all other remedies relating thereto which may affect the Premises or the
title thereto, and the Mortgagor shall at all times thereafter prosecute such
proceedings diligently and in good faith to completion; (ii) the Mortgagor shall
either (A) have duly paid the full amount of the tax or lien under protest or
(B) have fully bonded over or title-insured over such tax or lien to the
Mortgagee's full satisfaction; and (iii) the Mortgagee shall have notified the
Mortgagor that the Mortgagee is satisfied that the validity, priority, value and
utility of its lien and security interest on and in the Collateral will not be
adversely affected by such contest, objection or proceedings.


                      II.  D E F A U L T; R E M E D I E S

     The Mortgagor and the Mortgagee hereby agree further as follows:

     1.   Defaults; Acceleration.  The occurrence of an Event of Default under
          ----------------------                                              
any of the Credit Documents shall constitute a "Default" hereunder.  Upon the
occurrence of any Default, the entire indebtedness pursuant to the Credit
Agreement and all other Liabilities, together with interest thereon at the rate
applicable after maturity as provided in the Credit Agreement, shall become and
be immediately due and payable in accordance with the Credit Agreement.

     2.   Remedies Cumulative.  No remedy or right of the Mortgagee hereunder or
          -------------------                                                   
under the Credit Agreement or any other Security Documents or otherwise, or
available under applicable law, shall be exclusive of any other right or remedy,
but each such remedy or right shall be in addition to every other remedy or
right now or hereafter existing under any such document or under applicable law.
No delay in the exercise of, or omission to exercise, any remedy or right
accruing on any Default shall impair any such remedy or right or be construed to
be a waiver of any such Default or an acquiescence therein, nor shall it affect
any subsequent Default of the same or a different nature.  Every such remedy or
right may be exercised concurrently or independently, and when and as often as
may be deemed expedient by the Mortgagee.  All obligations of the Mortgagor, and
all rights, powers and remedies of the Mortgagee, expressed herein shall be in
addition to, and not in limitation of, those provided by law or in the Credit
Agreement or the Security Documents or any other written agreement or instrument
relating to any of the Liabilities or any security therefor.

     3.   Possession of Premises; Remedies under Credit Agreement.  The
          -------------------------------------------------------      
Mortgagor hereby waives all right to the possession, income, and rents of the
Premises from and after the occurrence of any Default, and, in accordance with
the Credit Agreement, the Mortgagee is hereby expressly authorized and
empowered, at and following any such occurrence, to enter into and upon and take
possession of the Premises or any part thereof, to complete any construction in
progress thereon at the expense of the Mortgagor, to lease the same, to collect
and receive all Rents and to apply the same, less the necessary or appropriate
expenses of collection thereof, either for the care, operation and preservation
of the Premises or, at the election of the Mortgagee in its sole and
unreviewable discretion, to a reduction of such of the Liabilities in such order
as the Mortgagee may elect.  The Mortgagee, in addition to the rights provided
under the Credit Agreement, is also hereby granted full and complete authority
to enter upon the Premises, employ watchmen to protect the Goods and
Improvements from depredation or injury and to preserve and protect the
Collateral, and to continue any and all outstanding contracts for the
construction and completion of Improvements to the Premises, to make and enter
into any contracts and obligations wherever necessary in its own name, and to
pay and discharge all debts, obligations and liabilities incurred thereby, all
at the expense of the Mortgagor.  All such expenditures by the Mortgagee shall
be Liabilities under this Mortgage for all purposes.  Upon the occurrence of any
Default, the Mortgagee may also exercise any or all rights or remedies under the
Credit Agreement.

     4.   Foreclosure; Receiver.  Upon the occurrence of any Default, the
          ---------------------                                          
Mortgagee shall also have the right, in accordance with the Credit Agreement,
immediately or at any time thereafter (in the Mortgagee's sole discretion), to
foreclose this Mortgage.  Upon the filing of any complaint for that purpose, the
court in which such complaint is filed shall, upon application of the Mortgagee
or at any time thereafter, either before or after foreclosure sale, and without
notice to the Mortgagor or to any person claiming under or through the Mortgagor
and without regard to the solvency or insolvency at the time of such application
of any person then liable for the payment of any of the Liabilities, without
regard to the then value of the Premises or whether the same shall then be
occupied, in whole or in part, as a homestead, by the owner of the equity of
redemption, and without regarding any bond from the complainant in such
proceedings, appoint a receiver for the benefit of the Mortgagee (and the
Mortgagor hereby irrevocably and unconditionally agrees and consents to the
appointment of any such receiver that the Mortgagee may designate or request or
that such court may appoint), with power to take possession, charge, and control
of the Premises, to lease the same, to keep the buildings thereon insured and in
good repair, and to collect all Rents during the pendency of such foreclosure
suit and during any period from the appointment of the receiver up to and
including the date of the confirmation of sale.  The court may, from time to
time, authorize said receiver to apply the net amounts remaining in his hands,
after deducting reasonable compensation for the receiver and his counsel as
allowed by the court, in payment (in whole or in part) of any or all of the
Liabilities, including without limitation the following, in such order of
application as the Mortgagee in its sole and unreviewable discretion may 

                                     -14-
<PAGE>
 
elect: (i) amounts due upon the Loans and Letters of Credit, (ii) amounts due
upon any decree entered in any suit foreclosing this Mortgage, (iii) costs and
expenses (including, without limitation, attorneys' fees and expenses) of
foreclosure and litigation upon the Premises, (iv) insurance premiums, repairs,
taxes, special assessments, water charges and interest, penalties and costs, in
connection with the Premises, (v) any other lien or charge upon the Premises
that may be or become superior to the lien of this Mortgage, or of any decree
foreclosing the same and (vi) all moneys advanced by the Mortgagee to cure or
attempt to cure any default by the Mortgagor in the performance of any
obligation or condition contained in the Credit Agreement, the Security
Documents or this Mortgage or otherwise, to protect the security hereof provided
herein, in the Credit Agreement or in any of the Security Documents, with
interest on such advances at the interest rate applicable after maturity under
the Credit Agreement. The surplus of the proceeds of sale, if any, shall then
(to the fullest extent permitted by applicable law) be paid to the Mortgagor
(and, if not permitted by law to be paid to the Mortgagor, such surplus shall be
paid and applied as required by applicable law). This Mortgage may be foreclosed
once against all, or successively against any portion or portions, of the
Premises, as the Mortgagee may elect, until all of the Premises have been
foreclosed against and sold. In case of any foreclosure of this Mortgage (or the
commencement of or preparation therefor) in any court, all expenses of every
kind paid or incurred by the Mortgagee for the enforcement, protection or
collection of this security, including court costs, attorneys' fees,
stenographers' fees, costs of advertising, and costs of title insurance and any
other documentary evidence of title, shall be paid by the Mortgagor.

     5.   Assignment of Rents; Remedies for Leases and Rents.  If any Default
          --------------------------------------------------                 
occurs, then, whether before or after institution of legal proceedings to
foreclose the lien of this Mortgage or before or after the sale thereunder, the
Mortgagee shall be entitled, in its discretion in accordance with the Credit
Agreement, to do all or any of the following:  (i) enter and take actual
possession of the Premises, the Rents, the Leases and other Collateral relating
thereto or any part thereof personally, or by its agents or attorneys, and
exclude the Mortgagor therefrom; (ii) with or without process of law, enter upon
and take and maintain possession of all of the documents, books, records, papers
and accounts of the Mortgagor relating thereto; (iii) as attorney-in-fact or
agent of the Mortgagor, or in its own name as mortgagee and under the powers
herein granted, hold, operate, manage and control the Premises, the Rents, the
Leases and other Collateral relating thereto and conduct the business, if any,
thereof either personally or by its agents, contractors or nominees, with full
power to use such measures, legal or equitable, as in its discretion or in the
discretion of its successors or assigns may be deemed proper or necessary to
enforce the payment of the Rents, the Leases and other Collateral relating
thereto (including actions for the recovery of rent, actions in forceable
detainer and actions in distress of rent); (iv) cancel or terminate any Lease or
sublease for any cause or on any ground which would entitle the Mortgagor to
cancel the same; (v) elect to disaffirm any Lease or sublease made subsequent
hereto or subordinated to the lien hereof; (vi) make all necessary or proper
repairs, decoration, renewals, replacements, alterations, additions, 

                                     -15-
<PAGE>
 
betterments and improvements to the Premises that, in its discretion, may seem
appropriate; (vii) insure and reinsure the Collateral for all risks incidental
to the Mortgagee's possession, operation and management thereof; and (viii)
receive all such Rents and proceeds, and perform such other acts in connection
with the management and operation of the Collateral, as the Mortgagee in its
discretion may deem proper, the Mortgagor hereby granting the Mortgagee full
power and authority to exercise each and every one of the rights, privileges and
powers contained herein at any and all times after any Default without notice to
the Mortgagor or any other person. The Mortgagee, in the exercise of the rights
and powers conferred upon it hereby, shall have full power to use and apply the
Rents to the payment of or on account of the following, in such order as it may
determine: (a) to the payment of the operating expenses of the Premises,
including the cost of management and leasing thereof (which shall include
reasonable compensation to the Mortgagee and its agents or contractors, if
management be delegated to agents or contractors, and it shall also include
lease commissions and other compensation and expenses of seeking and procuring
tenants and entering into Leases), established claims for damages, if any, and
premiums on insurance hereinabove authorized; (b) to the payment of taxes,
charges and special assessments, the costs of all repairs, decorating, renewals,
replacements, alterations, additions, betterments and improvements of the
Collateral, including the cost from time to time of installing, replacing or
repairing the Collateral, and of placing the Collateral in such condition as
will, in the judgment of the Mortgagee, make it readily rentable; and (c) to the
payment of any Liabilities.

     6.   Performance of Contracts.  The Mortgagee may, in its sole discretion
          ------------------------                                            
at any time after the occurrence of a Default in accordance with the Credit
Agreement, notify any person obligated to the Mortgagor under or with respect to
any Intangible, any Contract for Sale or any Contract for Construction of the
existence of a Default, require that performance be made directly to the
Mortgagee at the Mortgagor's expense, and advance such sums as are necessary or
appropriate to satisfy the Mortgagor's obligations thereunder; and the Mortgagor
agrees to cooperate with the Mortgagee in all ways reasonably requested by the
Mortgagee (including the giving of any notices requested by, or joining in any
notices given by, the Mortgagee) to accomplish the foregoing.

     7.   No Liability on Mortgagee.  Notwithstanding anything contained in this
          -------------------------                                             
Mortgage, the Mortgagee shall not be obligated to perform or discharge, and does
not undertake to perform or discharge, any obligation, duty or liability of the
Mortgagor, whether under this Mortgage, under any of the Leases, under any
Intangible, under any Contract for Construction, under any Contract for Sale or
otherwise, and the Mortgagor shall and does hereby agree to indemnify against
and hold the Mortgagee harmless of and from: (i) any and all liabilities, losses
or damages which the Mortgagee may incur or pay under or with respect to any of
the Collateral or under or by reason of its exercise of rights hereunder; and
(ii) any and all claims and demands whatsoever which may be asserted against it
by reason of any alleged obligations or undertakings on its part to perform or
discharge any of the terms, covenants or agreements contained in any of the
Collateral 

                                     -16-

or in any of the contracts, documents or instruments evidencing or creating any
of the Collateral, except for any liabilities, losses, damages, claims or
demands that arise from the Mortgagee's gross negligence or wilful misconduct.
The Mortgagee shall not have responsibility for the control, care, management or
repair of the Premises or be responsible or liable for any negligence in the
management, operation, upkeep, repair or control of the Premises resulting in
loss, injury or death to any tenant, licensee, employee, stranger or other
person. No liability shall be enforced or asserted against the Mortgagee in its
exercise of the powers herein granted to it, and the Mortgagor expressly waives
and releases any such liability. Should the Mortgagee incur any such liability,
loss or damage under any of the Leases or under or by reason hereof, or in the
defense of any claims or demands, the Mortgagor agrees to reimburse the
Mortgagee immediately upon demand for the full amount thereof, including costs,
expenses and attorneys' fees.

                              III  G E N E R A L

diminishing in any way the liability of the Mortgagor or any other person
(except any person expressly released in writing by the Mortgagee) for the
payment or performance of any of the Liabilities or for the performance of any
obligation contained herein or affecting the lien hereof upon the Collateral or
any part thereof, the Mortgagee may at any time and from time to time, without
notice to or the consent of any person, do any or all of the following: (i)
release any person liable (whether directly or indirectly, primarily or
secondarily, or otherwise) for the payment or performance of any of the
Liabilities; (ii) extend the time for, or agree to alter the terms of payment
of, any indebtedness under the Credit Agreement or any of the Liabilities; (iii)
modify or waive any obligation or performance; (iv) subordinate, modify or
otherwise deal with the lien hereof; (v) accept additional security of any kind;

right the Mortgagee may have.

     2.   Suits and Proceedings.  The Mortgagor agrees to indemnify the
          ---------------------                                        
Mortgagee, and hold the Mortgagee harmless, from and against any and all losses,
damages, costs, expenses and claims of any kind whatsoever (including, without
limitation, attorneys' fees) which the Mortgagee may pay or incur in connection
with any suit or proceeding in or to which the Mortgagee may be made or become a
party, which suit or proceeding does or may affect all or any portion of the
Collateral or the value, use or operation thereof or this Mortgage or the

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

          (a) The Mortgagor covenants that it will timely and fully perform and
     satisfy all the terms, covenants and conditions of the Credit Agreement and
     the Bond Lease in accordance with the terms thereof.

          (b) This Mortgage is granted to secure future advances and loans,
     including W/C Loans and LC Loans, from the Mortgagee and the Lenders to or
     for the benefit of the Mortgagor or the Premises, as provided in the Credit
     Agreement, regardless of whether, at the time or times of such advances,
     the Mortgagor is then the owner of the Collateral or any interest in any
     hereof, and costs and expenses of enforcing the Mortgagor's obligations
     under this Mortgage, the Credit Documents and the Credit Agreement.  All
     advances, disbursements or other payments required by the Credit Agreement
     are obligatory advances up to the credit limits established therein and
     shall, to the fullest extent permitted by law, have priority over any and
     all mechanics' liens and other liens and encumbrances arising after this
     Mortgage is recorded and shall be secured by this Mortgage.  Notice is
     hereby given that the indebtedness and Liabilities secured hereby may
     increase as a result of any defaults hereunder by the Mortgagor due to, for
     example, and without limitation, unpaid interest or late charges, unpaid
     taxes or insurance premiums which the Mortgagee elects to advance, defaults
     under leases that the Mortgagee elects to cure, attorney fees or costs
     incurred in enforcing the Loan Documents or other expenses incurred by the
     Mortgagee in protecting the Collateral, the security of this Mortgage or
     the Mortgagee's rights and interests.

     4.   Partial Releases. While not presently contemplated, it is possible
          ----------------                                                  
that the Mortgagee may from time to time consent in writing to one or more
partial releases of the lien of this Mortgage as it applies to one or more parts
of the Premises, but no such release (or any other release) shall affect the
lien of this Mortgage on the remainder of the Premises.

     5.   Security Agreement and Financing Statement.  This Mortgage, to the
          ------------------------------------------                        
extent that it conveys, grants a security interest in, or otherwise deals with
personal property or with items of personal property which are or may become
fixtures, shall also be construed as a security agreement, and also as a
financing statement, under the Uniform Commercial Code as in effect in the State
of Arkansas, with the Mortgagor as Debtor (with its address as set forth above)
and with the Mortgagee as Secured Party (with its address as set forth above).

     6.   Defeasance.  Upon full payment of all indebtedness secured hereby and
          ----------                                                           
full payment, performance and satisfaction of all the Liabilities in accordance
with their respective terms and at the time and in the manner provided, and when
the Mortgagee has no further obligation (whether contingent, conditional or
otherwise) to make any advance, 

                                     -18-
<PAGE>
 
disbursement or payment of any kind or to extend any credit under or with
respect to the Credit Agreement, this conveyance shall be null and void, and
thereafter, upon demand therefor, an appropriate instrument of quitclaim
reconveyance or release shall in due course be made by the Mortgagee to the
Mortgagor at the Mortgagee's expense.

     7.   Notices.  Each notice, demand or other communication in connection
          -------

addressee thereof in the manner set forth in the Credit Agreement.

     8.   Successors; The Mortgagor; Gender.  All provisions hereof shall inure

provided, however, that the foregoing shall not in any way limit, restrict or
modify the provisions of Article I, Section 4 above.  The word "Mortgagor" shall
include all persons claiming under or through the Mortgagor and all persons
liable for the payment or performance of any of the Liabilities whether or not
such persons shall have executed the Credit Agreement or this Mortgage. Wherever

     9.   Care by the Mortgagee.  The Mortgagee shall be deemed to have
          ---------------------                                        
exercised reasonable care in the custody and preservation of any of the
Collateral in its possession if it takes such action for that purpose as the
Mortgagor requests in writing, but failure of the Mortgagee to comply with any
such request shall not be deemed to be (or to be evidence of) a failure to
exercise reasonable care, and no failure of the Mortgagee to preserve or protect
any rights with respect to such Collateral against prior parties, or to do any
act with respect to the preservation of such Collateral not so requested by the
Mortgagor, shall be deemed a failure to exercise reasonable care in the custody
or preservation of such Collateral.

     10.  No Obligation on Mortgagee.  This Mortgage is intended only as
          --------------------------                                    
security for the Liabilities.  Anything herein to the contrary notwithstanding,
(i) the Mortgagor shall be and remain liable under and with respect to the
Collateral to perform all of the obligations assumed by it under or with respect
to each thereof, (ii) the Mortgagee shall have no obligation or liability under
or with respect to the Collateral by reason or arising out of this Mortgage and
(iii) the Mortgagee shall not be required or obligated in any manner to perform
or fulfill any of the obligations of the Mortgagor under, pursuant to or with
respect to any of the Collateral.

     11.  No Waiver by the Mortgagee; Writing.  No delay on the part of the
          -----------------------------------                              
Mortgagee in the exercise of any right or remedy shall operate as a waiver
thereof, and no single or partial exercise by the Mortgagee of any right or
remedy shall preclude other or further exercise thereof or the exercise of any
other right or remedy.  No amendment, waiver or supplement in any way affecting
this Mortgage shall in any event be effective unless set out in a writing signed
by the Mortgagee.

     12.  Governing Law; Severability; Section Headings.  This Mortgage has been
          ---------------------------------------------                         
executed and delivered at Chicago, Illinois, where the Mortgagee maintains its
principal place of business, and shall be construed in accordance with and
governed by the laws of the State of Illinois except for the lien rights and
remedies pertaining thereto which must be governed by the laws of the state in
which the premises are situated, regarding which Arkansas law shall govern.
Whenever possible, each provision of this Mortgage shall be interpreted in such
manner as to be effective and valid under applicable law, but if any provision
of this Mortgage shall be prohibited by or invalid under applicable law, such
provision shall be ineffective to the extent of such prohibition or invalidity
only, without invalidating the remainder of such provision or the remaining
provisions of this Mortgage, it being the parties' intention that this Mortgage
and each provision hereof be effective and enforced to the fullest extent
permitted by applicable law.  The Section headings used herein are for
convenience of reference only, and shall not be deemed to be a part of this
Mortgage or be considered in the interpretation, or construction thereof.

     13.  No Merger.  It being the desire and intention of the parties hereto
          ---------                                                          
that this Mortgage and the lien hereof do not merge in fee simple title to the
Premises, it is hereby understood and agreed that should the Mortgagee acquire
an additional or other interests in or to the Premises or the ownership thereof,
then, unless a contrary intent is manifested by the Mortgagee as evidenced by an
express statement to that effect in an appropriate document duly recorded, this
Mortgage and the lien hereof shall not merge in the fee simple title, toward the
end that this Mortgage may be foreclosed as if owned by a stranger to the fee
simple title.

     14.  Mortgagee Not a Joint Venturer or Partner.  The Mortgagor and the
          -----------------------------------------                        
Mortgagee acknowledge and agree that in no event shall the Mortgagee be deemed
to be a partner or joint venturer with the Mortgagor.  Without limitation of the
foregoing, the Mortgagee shall not be deemed to be such a partner or joint
venturer on account of its becoming a mortgagee in possession or exercising any
rights pursuant to this Mortgage or pursuant to any other instrument or document
evidencing or securing any of the Liabilities secured hereby, or otherwise.

     15.  Limited Recourse.  The limitations on recourse set forth in Section 11
          ----------------                                                      
of the Credit Agreement are expressly incorporated herein by reference.

     16.  No Reliance by Others on the Premises.  The Mortgagor covenants that
          -------------------------------------                               
it will not cause or permit any land, building or other improvement, or other
property of any kind whatsoever which is not subject to the lien of this
Mortgage (regardless of whether such property is owned by the Mortgagor) to rely
on the Premises or any part thereof or any interest therein to fulfill any
municipal or governmental requirement of any kind whatsoever, and the Mortgagor
hereby assigns to the Mortgagee any and all rights to give or withhold consent
for all or any portion of the Premises or any interest therein to be so used.
The Mortgagor represents, warrants and covenants that no building or other

                                     -20-
<PAGE>
 
improvement situated on or comprising part of the Premises does, or at any time
will, rely on any property not subject to the lien of this Mortgage to fulfill
any governmental or municipal requirement of any kind whatsoever. Any act or
omission by the Mortgagor which would result in a violation of any of the
provisions of this Section shall be void abinitio and of no force or effect for
                                         --------
any purpose whatsoever.

     17.  No Property Manager's Lien.  Any property management agreement for or
          --------------------------                                           
relating to all or any part of the Premises, whether now in effect or entered
into hereafter by the Mortgagor or any agent of the Mortgagor, with a property
manager shall contain a "no lien" provision whereby the property manager forever
and unconditionally waives and releases any and all mechanics' lien rights and
claims that it or anyone claiming through or under it may have at any time
pursuant to any statute or law.  Such property management agreement or a short
form thereof including such waiver shall, at the Mortgagee's request, be
recorded with the Office of the Recorder of Deeds for the county in which the
Premises are located.  In addition, the Mortgagor shall cause the property
manager to enter into a subordination agreement with the Mortgagee, in
recordable form, whereby the property manager subordinates its present and
future lien rights and those of any party claiming by, through or under it, to
the lien of this Mortgage.  The Mortgagor's failure to cause any of the
foregoing to occur shall constitute a default under this Mortgage.

     18.  WAIVERS.
          ------- 

     THE MORTGAGOR, ON BEHALF OF ITSELF AND ALL PERSONS NOW OR HEREAFTER
INTERESTED IN THE PREMISES OR THE COLLATERAL, VOLUNTARILY AND KNOWINGLY HEREBY

BEHALF OF EACH AND EVERY PERSON ACQUIRING ANY INTEREST IN OR TITLE TO THE
PREMISES SUBSEQUENT TO THE DATE OF THIS MORTGAGE, HEREBY IRREVOCABLY WAIVES ANY

consideration of the premises and of the elements of consideration recited in
the granting clause (i.e., the first paragraph following the caption "Grant")
                     ---                                                     
above, the Mortgagor hereby grants and conveys to the Mortgagee and its
successors and assigns until the Liabilities have been paid in full an easement
(the "Environmental Easement") to enter on, upon and within the Premises in
accordance with the Credit Agreement at any time and from time to time for the
purpose of making such tests, inspections, investigations and examinations
(including, without limitation, soil borings and tests and other subsurface
explorations, investigations, examinations and tests) as the Mortgagee, in its
discretion, deems necessary, convenient, or useful to enable it to determine (i)
whether any Hazardous Materials are or may be present on, under, upon or within
the Premises or any part thereof and (ii) whether the ownership, use, condition,
and operation of the Premises and the conduct of the activities engaged in
thereat are in compliance with federal, state, and local environmental laws,
rules, and regulations.  The Mortgagor hereby irrevocably grants to the
Mortgagee and its agents, contractors and designees the right, in accordance
with the Credit Agreement, to 

                                     -22-
<PAGE>
 
inspect and copy all of the Mortgagor's records relating to environmental
matters and to enter all buildings, improvements, and facilities of the
Mortgagor for such purpose. The Mortgagor hereby grants to the Mortgagee a
continuing security interest in and to all of the Mortgagor's existing and
future records that relate in any way to any environmental matters, whether
located at the Premises or elsewhere, whether in the possession or control of
the Mortgagor or any other person (including any federal, state, or local agency
or instrumentality), and whether written, photographic, computerized, or in any
other form, state or condition, and the proceeds and products thereof. The
Mortgagee or its agent, contractor or designee may, in accordance with the
Credit Agreement, interview any or all of the Mortgagor's agents, employees, and
independent contractors and consultants regarding environmental matters,
including any consultants or experts retained by the Mortgagor, all of whom are
hereby irrevocably authorized and directed by the Mortgagor to discuss
environmental issues fully and openly with the Mortgagee and its agents,
contractors and designees and to provide to them such information as may be
requested by any of them. All reasonable costs and expenses paid or incurred by
the Mortgagee pursuant to this Section 1 of Article IV for or with respect to
the tests, inspections, investigations and examinations which the Mortgagee may
conduct, including (without limitation) the fees and expenses of the Mortgagee's
consultants, engineers, laboratories, and contractors, shall be paid by the
Mortgagor on demand by the Mortgagee. The Mortgagee may, but shall not be
required to, advance such costs and expenses on behalf of the Mortgagor. All
sums so advanced shall bear interest at the highest rate provided with respect
to the Loan, and all such advances shall be deemed indebtedness owing under the
Credit Agreement and secured by the Security Documents.

     2.   Duration and Defeasance.  The Environmental Easement shall exist and
          -----------------------                                             
continue until such time as all of the Liabilities have been fully paid,
performed and satisfied, the Mortgagee has no further obligation to advance any
amounts to the Mortgagor under or with respect to the Credit Agreement or any of
the Credit Documents, and this Mortgage has been released of record.  A release
of this Mortgage shall also be deemed to constitute and evidence a termination
of the Environmental Easement.

     3.   Enforcement.  The Mortgagor (i) acknowledges that no adequate remedy
          -----------                                                         
at law exists for a violation of the Environmental Easement or for the
Mortgagor's failure or refusal to provide to the Mortgagee any or all of the
access, rights or other benefits set out or described in any provision of this
Article IV, and (ii) agrees that the Mortgagee shall have the right to enforce
the Environmental Easement and all of the other provisions of this Article IV by
any and all equitable writs, decrees, remedies and relief (including, without
limitation, temporary and preliminary injunctive relief).  The Mortgagor agrees
to pay all of the Mortgagee's costs and expenses of enforcement (including,
without limitation, court costs and attorneys' fees and expenses) of the
provisions of this Article IV.

     4.   Running with the Land; Assignability.  The Environmental Easement is
          ------------------------------------                                
intended to be and shall be construed as an interest in the Premises and as an
easement 

                                     -23-
<PAGE>
 
in gross; it is not intended to be a personal right of the Mortgagee or a mere
license. The Environmental Easement, and all rights and benefits of the
Mortgagee as set out in this Article IV, shall run with and bind the Land and
the Premises, shall be binding upon all successor owners of any and every estate
and interest in the Premises, and shall be deemed to have been assigned to and
be enforceable by and inure to the benefit of whomever holds the indebtedness
secured by this Mortgage.

     5.   Revocability.  The Environmental Easement is irrevocable.
          ------------                                             

     6.   Mortgagee not Mortgagee in Possession.  The exercise of the rights
          -------------------------------------                             
granted hereunder shall not constitute the Mortgagee a mortgagee in possession
with respect to the Premises.

     7.   Mortgagor's Understanding.  The Mortgagor acknowledges that it has
          -------------------------

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

     (a)  Unconditional Obligations.  The obligations of the Equity Owner
          -------------------------                                      
hereunder are absolute and unconditional, without regard to any circumstance of
any nature whatsoever that constitutes or might constitute an equitable or legal
discharge of the Company, Deltic or any other Member of any of its respective
obligations under the Credit Documents, in bankruptcy or in any other instance.
To the extent permitted by applicable law, the Equity Owner hereby waives
diligence, presentment, protest, demand for payment and notice of default or
non-payment to or upon the Company or itself with respect to any amounts due
under the Credit Agreement or any other Credit Document.  The Equity Owner shall
remain obligated hereunder notwithstanding that, without any reservation of
rights by or against the Equity Owner and without notice to or further assent by
or against the Equity Owner, any demand for payment of any amount due pursuant
to the Credit Agreement or the other Credit Documents may be rescinded by the
Secured Parties, or any of the loans or other extensions of credit thereunder
continued or such amounts, or the liability of any other Person upon or for any
part thereof, or any collateral security or guaranty therefor or right of offset
with respect thereto, may, from time to time, in whole or part, be renewed,
extended, amended, modified, accelerated, compromised, waived, surrendered or
released by the Secured Parties, or the Credit Agreement, the Temple-Inland
Equity Contribution Agreement or any other Credit Document or any other document
executed in connection therewith may be amended, modified, supplemented or
terminated, in whole or in part, as the Secured Parties may deem advisable from
time to time, or any collateral security or 

                                      -5-
<PAGE>
 
guaranty or right of offset at any time held by the Secured Parties for the
payment of such amounts may be sold, exchanged, waived, surrendered or released;
provided, that no such amendment shall increase, accelerate, modify or otherwise
- --------                        
alter any obligations of the Equity Owner hereunder in any respect without the
Equity Owner's consent.

          (b)  Exercise of Remedies, etc.  When pursuing its rights and remedies

but shall be under no obligation to, pursue such rights and remedies as it may
have against any collateral security or right of offset with respect to any
amounts due under the Credit Agreement, the Temple-Inland Equity Contribution
Agreement or any other Credit Document, and any failure by the Secured Parties
to pursue such other rights or remedies or to collect any payments from the
Company or any such other Person or to realize upon any collateral security or
to exercise any right of offset, or to release the Company or any such other
Person or any collateral security or right of offset shall not relieve the
Equity Owner of any of its liability hereunder, and shall not impair or affect
the rights and remedies, whether express, implied or available as a matter of
law, of the Secured Parties against the Equity Owner.  No delay on the part of
any Secured Party in the exercise of any right or remedy shall operate as a
waiver thereof, and no single or partial exercise by any Secured Party of any
right or remedy shall preclude any further exercise thereof. The failure of any
Secured Party at any time or times hereafter to require strict performance by
the Equity Owner of any of the provisions, warranties, terms and conditions
applicable to the Equity Owner contained in any agreement, guarantee, instrument
or document now or at any time or times hereafter executed by the Equity Owner
with respect to the Equity Owner's obligations hereunder and delivered to any
Secured Party shall not result in the waiver of or affect or diminish any right
of the Agent at any time or times thereafter to demand strict performance of the
obligations applicable to any  hereunder and such right shall not be deemed to
have been waived by any act or knowledge of any Secured Party other than by a
specific written waiver by the appropriate Secured Parties.  No waiver by any
Secured Parties of any default or failure to pay when due all or any portion of
the obligations applicable to the Equity Owner hereunder shall operate as a
waiver of any other default or failure or the same default or failure on a
future occasion.  None of the Secured Parties shall have any liability for the
performance or observance of any of the obligations or duties of the Company
under the Credit Agreement or under any other Project Document and the Company's
failure to perform any such obligations or duties shall not impair the
obligations of the Equity Owner hereunder.

5.   REMEDIES.

     5.1. Acceleration and Remedies.  If any Pledgor Default occurs, the Agent
          -------------------------                                           
shall, if so requested by the Required Lenders, exercise any or all of the
rights and remedies provided in this Pledge Agreement or any other Credit
Document, in the Uniform Commercial Code as in effect in Illinois or by any
other applicable law. Without limiting the foregoing, whenever Pledgor Default
shall exist and be continuing the Agent (a) shall, if so requested by the
Required Lenders, to the fullest extent permitted by applicable law, without
notice, advertisement, hearing or process of law of any kind, (i) sell any or
all of the Collateral, free of all rights and claims of any Pledgor therein and
thereto, at any public or private sale or brokers' board and (ii) bid for and
purchase any or all of the Collateral at any such public sale; and (b) shall
have the right, for and in the name, place and stead of any Pledgor, to execute
endorsements, assignments, stock powers and other instruments of conveyance or
transfer with respect to all or any of the Collateral.  Each Pledgor hereby
expressly waives, to the fullest extent permitted by applicable law, any and all
notices, advertisements, hearings or process of law in connection with the
exercise by the Agent of any of its rights and remedies during the continuance
of a Pledgor Default.  If any notification of intended disposition of any of the
Collateral is required by law, such notification, if mailed, shall be deemed
reasonably and properly given if mailed by certified or registered mail at least
ten (10) days before such disposition, postage prepaid, addressed to any
Pledgor, either at the address of such Pledgor shown below, or at any other
address of such Pledgor appearing on the records of the Agent.  Any proceeds of
any of the Collateral may be applied by the Agent to the payment of expenses in
connection with the Collateral, including, without limitation, reasonable
attorneys' fees and legal expenses, and any balance of such proceeds may be
applied by the Agent toward the payment of such of the Liabilities, and in such
order of application, as the Agent may 

                                      -6-
<PAGE>
 
from time to time elect (and, after payment in full of all Liabilities, any
excess shall be delivered to the applicable Pledgor or as a court of competent
jurisdiction shall direct).

     The Agent is hereby authorized to comply with any limitation or restriction
in connection with any sale of Collateral as it may be advised by counsel is
necessary in order to (a) avoid any violation of applicable law (including,
without limitation, compliance with such procedures as may restrict the number
of prospective bidders and purchasers and/or further restrict such prospective
bidders or purchasers to persons or entities who will represent and agree that
they are purchasing for their own account for investment and not with a view to
the distribution or resale of such Collateral) or the loss of qualifying
facility status for the Facility or (b) obtain any required approval of the sale
or of the purchase by any governmental regulatory authority or official, and
each Pledgor agrees that such compliance shall not result in such sale being
considered or deemed not to have been made in a commercially reasonable manner
and that the Agent shall not be liable or accountable to such Pledgor for any
discount allowed by reason of the fact that such Collateral is sold in
compliance with any such limitation or restriction.

     5.2  Care of Collateral.  The Agent shall be deemed to have exercised
          ------------------                                              
reasonable care in the custody and preservation of the Collateral if it takes
such action for that purpose as any Pledgor shall request in writing, but
failure of the Agent to comply with any such request shall not of itself be
deemed a failure to exercise reasonable care, and no failure of the Agent to
preserve or protect any rights with respect to the Collateral against prior
parties, or to do any act with respect to preservation of the Collateral not so
requested by such Pledgor, shall be deemed of itself a failure to exercise
reasonable care in the custody or preservation of any Collateral.

     5.3  Sharing of Collateral.  The Secured Parties agree that the net
          ---------------------                                         
proceeds of any sale or disposition of the Collateral after the occurrence of a
Pledgor Default shall be distributed among the Secured Parties as set forth in
the Security Agreement.

     5.4  Registration of Collateral.  At the option of the Agent, any
          --------------------------                                  
registerable Collateral may at any time be registered in the name of the Agent
or its nominee.

     5.5  Exercise of Rights in Collateral.  After the occurrence of a Pledgor
          --------------------------------                                    
Default, the Agent and/or the Secured Parties or their nominee may at any time
and from time to time, without notice, exercise all voting, corporate,
managerial and membership rights relating to the Collateral, including, without
limitation, rights to receive dividends and distributions, as well as exchange,
subscription or any other rights, privileges, or options pertaining to the
Membership Interests and the Additional Rights as if it were the absolute owner
thereof.

6.   WAIVERS, AMENDMENTS AND REMEDIES.

     No delay or omission of the Agent or the Secured Parties to exercise any
right or remedy granted under this Pledge Agreement shall impair such right or
remedy or be construed to be a waiver of any Pledgor Default or an acquiescence
therein, and any single or partial exercise of any such right or remedy shall
not preclude other or further exercise thereof or the exercise of any other
right or remedy, and no waiver, amendment or other variation of the terms,
conditions or provisions of this Pledge Agreement whatsoever shall be valid
unless in writing signed by the Agent, and then only to the extent in such
writing specifically set forth.  All rights and remedies contained in this
Pledge Agreement or by law afforded shall be cumulative and all shall be
available to the Agent and the Secured Parties until the Liabilities have been
paid in full and all commitments to lend under the Credit Agreement have been
terminated.

7.   GENERAL PROVISIONS.

     7.1  Specific Performance of Certain Covenants.  Each Pledgor acknowledges
          -----------------------------------------                            
and agrees that a breach of any of the covenants contained in Sections 4.1.(a),
                                                                       ------- 
4.1.(d), 4.2.(b), 4.2.(c) and 4.2.(d), will cause irreparable injury to the
- -------  -------  -------     -------                                      
Secured Parties, that the Secured Parties have no adequate remedy at law in
respect of such breaches and therefore agrees, without limiting the right of the
Agent and the Secured Parties to seek and obtain specific performance of other
obligations of such Pledgor contained in this Pledge Agreement, that the
covenants of such Pledgor contained in the Sections referred to in this Section
                                                                        -------

          -------------------------                                            
are absolute and unconditional, without regard to any circumstance of any nature
whatsoever that constitutes or might constitute an equitable or legal discharge
of the Company or any Pledgor of any of its respective obligations under the
Credit Documents, in bankruptcy or in any other instance.  To the extent
permitted by applicable law, each Pledgor hereby waives diligence, presentment,
protest, demand for payment and notice of default or non-payment to or upon the
Company or itself with respect to any amounts due under the Credit Agreement or
any other Credit Document. Each Pledgor shall remain obligated hereunder
notwithstanding that, without any reservation of rights by or against such
Pledgor and without notice to or further assent by or against such Pledgor, any
demand for payment of any amount due pursuant to the Credit Agreement or the
other Credit Documents may be rescinded by the Secured Parties, or any of the
loans or other extensions of credit thereunder continued or such amounts, or the
liability of any other Person upon or for any part thereof, or any collateral
security or guaranty therefor or right of offset with respect thereto, may, from
time to time, in whole or part, be renewed, extended, amended, modified,
accelerated, compromised, waived, surrendered or released by the Secured
Parties, or the Credit Agreement, the Notes or any other Credit Documents or any
other document executed 

                                      -8-
<PAGE>
 
in connection therewith may be amended, modified, supplemented or terminated, in
whole or in part, as the Secured Parties may deem advisable from time to time,
or any collateral security or guaranty or right of offset at any time held by
