     The following summary is qualified in its entirety by the more detailed
information and the Consolidated Financial Statements, including Notes thereto,
appearing elsewhere in this Prospectus. References to pro forma financial
information should be read in conjunction with the Pro Forma Condensed
Consolidated Financial Statements included elsewhere in this Prospectus. Unless

references to the "Company" or to "Denali" refer to Denali Incorporated, its
predecessors and subsidiaries.
 
                                  THE COMPANY
 
   
     Denali Incorporated is a rapidly growing provider of products and services
for handling critical fluids, which are fluids that are economically valuable or
potentially hazardous to the environment. The Company believes that it is a
leading manufacturer of fiberglass composite underground storage tanks ("USTs"),
steel rectangular aboveground storage tanks ("ASTs") and engineered fiberglass
reinforced composites for handling corrosive fluids. Critical fluids handling
products and services are used in a wide variety of applications, including in
retail petroleum marketing and in petroleum, chemical, pulp and paper, electric
power and other industrial process plants.
    
 
BACKGROUND
 
     The Company was formed in 1994 to acquire the fiberglass composite UST
business of Owens Corning. Initially, the Company focused its efforts on
improving profitability, improving responsiveness to customers and developing
new products. The Company's management also realized that the critical fluids
handling industry was highly fragmented and that there would be significant
opportunities to consolidate the industry.
 
   
     In October 1995, the Company acquired Hoover Containment, Inc. ("Hoover"),
a manufacturer of steel rectangular ASTs, and, in February 1997, the Company
acquired Ershigs, Inc. ("Ershigs"), a manufacturer of engineered fiberglass
reinforced plastic ("FRP") products for handling corrosive fluids.
    
 
   
     In October 1997, the Company acquired GL&V LaValley Construction, Inc.
("LaValley"), another manufacturer of engineered FRP products, and SEFCO, Inc.
("SEFCO"), a fabricator of engineered field-erected steel tanks.
    
 
     Prior to forming the Company, the Company's Chairman and Chief Executive
Officer, Stephen T. Harcrow, was President of EnviroTech, a business unit of
Baker Hughes Incorporated, from 1988 to 1993. EnviroTech was a manufacturer of
equipment for process industries. During Mr. Harcrow's tenure as President,
EnviroTech grew through the acquisition of manufacturers of fluid separation,
pumping and measurement products, with annual revenues increasing from
approximately $365 million up to $680 million. Since the Company's formation,
five other former employees of EnviroTech have joined the Company as executive
officers.
 
PRODUCTS AND SERVICES
 
     Containment Products. The Company's Containment Products Group specializes
in the manufacture of fiberglass composite USTs and steel rectangular ASTs. The
Company's fiberglass composite USTs, manhole products and oil/water separators
are marketed under the Fluid Containment tradename and its steel rectangular
ASTs are marketed under the Hoover and LubeCube(R) tradenames.
 
   
     Engineered Products. The Company's Engineered Products Group specializes in
providing custom engineered FRP products and engineered metal products for the
pulp and paper, power, chemical, water and wastewater and other process
industries. The Company markets its engineered FRP products under the Ershigs
tradename and believes that it is a leading domestic provider of engineered FRP
products for corrosion resistant applications. SEFCO is an integrated
manufacturer of engineered field-erected steel tanks and accessories for use in
the water and wastewater, agrochemical and petroleum industries. This group
focuses its operations on complex projects, where custom engineering and special
manufacturing expertise are critical.

BUSINESS STRATEGY
 
     The Company's objective is to become the leading provider of a broad range
of products and services for handling critical fluids through strategic
acquisitions and internal growth. The Company believes that the fragmented
nature of the critical fluids handling industry, which is comprised of many
companies with limited product ranges or serving limited geographic areas, will
provide continued acquisition and internal growth opportunities. The Company
also believes that these opportunities provide the Company with the ability to
offer a comprehensive range of specialized solutions for meeting its customers'
critical fluids handling needs.
 
   
     Acquisition Strategy. Since its founding in 1994, the Company has completed
five acquisitions. The Company's net sales have grown from approximately $17.8
million for fiscal 1995 (a 28-week period ended July 1, 1995) to $71.1 million
for fiscal 1997. Pro forma net sales for fiscal 1997 were approximately $104.9
million, including approximately $17.9 million with respect to the recent
acquisitions of SEFCO and LaValley. Net loss for fiscal 1995 was $43,000 and
increased to net income of $317,000 for fiscal 1997 and was $595,000 for pro
forma first quarter fiscal 1998, excluding a $2.3 million non-recurring
compensation charge. In addition, EBITDA (as defined in "Summary Consolidated
Financial Data") increased from $981,000 for fiscal 1995 to approximately $3.9
million for fiscal 1997 and was $2.3 million for pro forma first quarter fiscal
1998. Key elements of the Company's acquisition strategy include:
    
 
     - Develop a Comprehensive Range of Products and Services. The Company's
       existing products offer a variety of containment and engineered materials
       solutions for handling critical fluids. The Company intends to broaden
       its product lines to introduce additional critical fluid separation and
       measurement products. The Company believes that the ability to offer a
       comprehensive range of critical fluids handling products and services
       will be a competitive advantage.
 
   
     - Expand Within Existing Markets. The Company intends to expand its product
       offerings within the geographic markets it currently serves. For example,
       the SEFCO acquisition is expected to expand the Company's engineered
       product capabilities into the field fabrication of tanks.
    
 
   
     - Penetrate New Geographic Markets, Including International Markets. The
       Company believes that it can expand its operations that are regional in
       nature throughout the United States and internationally. For example, the
       acquisition of LaValley is expected to strengthen the Company's market
       position in the Gulf Coast region for the Company's engineered products.
       In addition, the Company intends to pursue license agreements for the
       international manufacture of certain products.
    
 
     Internal Growth Strategy. The Company is also focused on expanding the
scope and profitability of each of the businesses it acquires. Key elements of
this growth strategy are:
 
     - Promote Internal Growth through a Decentralized Structure. The Company
       employs a decentralized management and operational structure to
       capitalize on market knowledge, product expertise, name recognition and
       customer relationships.
 
     - Reduce Product and Administrative Costs. The Company's consolidation
       effort has led to raw materials purchasing economies, manufacturing
       efficiencies, increased sales coverage and product transportation cost
       reductions. In addition, the Company has improved operating margins by
       consolidating administrative functions such as finance, insurance and
       employee benefits.
 
     - Develop New Products. The Company utilizes the technological expertise,
       market knowledge and customer relationships of the businesses it acquires
       to develop new products. For example, as a result of the Company's
       development efforts, sales of oil/water separators and FRP manhole
       products have increased from approximately $500,000 for fiscal 1995 to
       more than $2.3 million for fiscal 1997.
 
     - Utilize Available Manufacturing Capacity. The Company also believes new
       products, acquired businesses and growth of current product net sales
       will increase manufacturing and facility utilization, contributing to
       further increases in profitability.
 
     The Company's principal offices are located at 1360 Post Oak Boulevard,
Suite 2470, Houston, Texas 77056, and its telephone number is (713) 627-0933.

                      SUMMARY CONSOLIDATED FINANCIAL DATA
                    (IN THOUSANDS, EXCEPT PER SHARE AMOUNTS)
 
   
     The summary consolidated financial data for the period December 19, 1994
(date of inception) to July 1, 1995, and the years ended June 29, 1996 and June
28, 1997, have been derived from the Company's Consolidated Financial
Statements, which have been audited by Ernst & Young LLP. The Company operates
on a 52/53 week fiscal year ending on the Saturday closest to June 30. The
summary historical consolidated financial data for the three months ended
September 28, 1996 and September 27, 1997 have been derived from the unaudited
consolidated financial statements of the Company, which in the opinion of
management include all adjustments (consisting of normal recurring adjustments)
necessary for a fair presentation of the periods presented. The results of
operations for the three months ended September 27, 1997 are not necessarily
indicative of the results of operations to be expected for the year. References
to fiscal years by date refer to the fiscal year ending in that calendar year;
for example, "fiscal 1997" refers to the fiscal year ended June 28, 1997.

(1) Gives effect to the acquisitions of Ershigs, LaValley and SEFCO, as if such
    acquisitions had been consummated as of June 30, 1996, the beginning of the
    period presented, and should be read in conjunction with the Pro Forma
    Condensed Consolidated Financial Statements included elsewhere in this
    Prospectus. The pro forma results of operations are not necessarily
    indicative of the results that would have occurred had the acquisitions been
    consummated as of the beginning of the period.
    
 
   
(2) Supplemental earnings (loss) per common share, which give effect to this
    Offering as if it had occurred at the beginning of the periods presented,
    were $0.40 and $(0.40)for the year ended June 28, 1997 and the three months
    ended September 27, 1997, respectively. See Notes 2 and 18 to Consolidated
    Financial Statements.
    
 
   
(3) EBITDA represents earnings before interest expense, income tax, depreciation
    and amortization and non-recurring compensation expense. The Company
    believes that EBITDA is a meaningful measure of its operating performance;
    however, EBITDA should not be considered in isolation from or as a
    substitute for net income or cash flow measures prepared in accordance with
    generally accepted accounting principles or as a measure of a company's
    profitability or liquidity. In addition, EBITDA may not be comparable to
    similarly titled measures reported by other companies.
    
 
   
(4) Gives effect to the acquisitions of LaValley and SEFCO as if such
    acquisitions had been completed on June 28, 1997.
    
 
(5) Gives effect to the Offering and the application of the estimated net
    proceeds therefrom as set forth under "Use of Proceeds." See
    "Capitalization."
 
   
(6) For the three months ended September 27, 1997 net income attributable to
    Common Stock and net income per common share were $317,000 and $0.14,
    respectively, excluding the impact of a non-recurring charge related to a
    compensation charge of $2,312,000 for the exchange of a subsidiary's stock
    options for stock options to purchase the Company's Common Stock. See Note 6
    of Notes to Consolidated Financial Statements (unaudited) for the three
    months ended September 27, 1997. Also, for the three months ended September
    27, 1997 pro forma net income attributable to Common Stock and pro forma net
    income per common share were $565,000 and $0.25, respectively, excluding the
    non-recurring charge discussed above.

                                  RISK FACTORS
 
     Prospective investors should carefully consider the following factors, as
well as the other information contained in this Prospectus.
 
DEPENDENCE ON INDUSTRY SPENDING
 
     The prospects for the Company depend upon the level of capital and
maintenance expenditures by its industrial customers. These industries
historically have been cyclical in nature and vulnerable to general downturns in
the economy. No assurance can be given that the Company will be able to increase
or maintain its level of sales in periods of economic stagnation or downturn.
Decreases in industry spending could have a significant adverse effect upon the
demand for the Company's products and services and the Company's results of
operations.
 
LIMITED OPERATING HISTORY
 
     The Company commenced operations in December 1994 and has only a limited
operating history upon which investors may base an evaluation of its
performance. The likelihood of success of the Company must be considered in
light of the risks, expenses, difficulties and delays frequently encountered in
connection with the operation and development of new and expanding businesses.
 
ABILITY TO MANAGE GROWTH AND ACHIEVE BUSINESS STRATEGY
 
   
     Since 1994, the Company has completed five acquisitions of businesses in
pursuit of its strategic objectives. The Company plans to continue to pursue
acquisitions that complement its existing products and services. The Company
expects to face competition for acquisition candidates, which may limit the
number of acquisition opportunities and may lead to higher acquisition prices.
There can be no assurance that the Company will be able to identify, acquire or
manage profitably additional businesses or to integrate successfully any
acquired businesses into the Company without substantial costs, delays or other
operational or financial difficulties. Further, acquisitions involve a number of
special risks, including failure of the acquired business to achieve expected
results, diversion of management's attention, failure to retain key personnel of
the acquired business and risks associated with unanticipated events or
liabilities, some or all of which could have a material adverse effect on the
Company's business, financial condition and results of operations. In addition,
there can be no assurance that the businesses the Company has acquired or may
acquire in the future will achieve anticipated net sales and earnings. See
"Business -- Strategy."
    
 
NEED FOR ADDITIONAL CAPITAL; LEVERAGE AND LIQUIDITY
 
     The Company has experienced and expects to continue to experience
substantial working capital needs to fund it operations. Although the Company
believes that based on its current operations it will be able to meet the
interest and principal obligations on its indebtedness and to fund its capital
expenditures and other operating expenses out of cash flow from operations and
available borrowings under its principal credit facility over the next 12
months, there can be no assurance that the Company's business will continue to
generate cash flow at levels sufficient to meet these requirements. Further, the
Company plans to effect future acquisitions to pursue its business strategy
which may require additional financing. No assurance can be given as to the
availability or terms of any such additional financing that may be required.
 
   
     At November 1, 1997, after giving effect to the issuance of the Common
Stock offered hereby and the application of the net proceeds therefrom to repay
indebtedness and to redeem certain shares of the Company's Series A Preferred
Stock, the Company would have had total indebtedness of approximately $7.6
million and debt as a percentage of total capitalization of 22.5%. Although the
Company's current amount of indebtedness, as adjusted, is relatively low, the
Company has been highly leveraged in the past and may increase the level of its
indebtedness in the future to fund its current operations or to finance
additional acquisitions. The degree to which the Company will be leveraged could
have important consequences, including the following: (i) the possible
impairment of the Company's ability to obtain financing in the future for
potential acquisitions, working capital, capital expenditures and general
corporate purposes; (ii) the
    
 
                                        8
<PAGE>   10
 
necessity for a substantial portion of the Company's cash flow from operations
to be dedicated to the payment of principal and interest on its indebtedness;
and (iii) the potential for increased vulnerability of the Company to economic
downturns and possible limitation of its ability to withstand competitive
pressures. The Company's ability to meet its debt service obligations will be
dependent upon the Company's future performance, which will be subject to
general economic conditions and to financial, business and other factors
affecting the operations of the Company, many of which are beyond its control.
 
RISKS RELATED TO INTERNAL GROWTH STRATEGY
 
     Key elements of the Company's strategy are to improve the profitability of
its businesses and any businesses it may subsequently acquire and to continue to
expand the net sales of such businesses. Although the Company intends to seek to
improve the profitability of such businesses by various means, including
reducing administrative and other costs, there can be no assurance that the
Company will be able to do so. The Company's ability to increase the net sales
of such businesses will be affected by various factors, including demand for
products, the Company's ability to expand the range of products and services
offered by each of such businesses and the Company's ability to successfully
enter new markets. Many of these factors are beyond the control of the Company,
and there can be no assurance that the Company's strategies will be successful
or that it will be able to generate cash flow adequate for its operations and to
support internal growth. See "Business -- Business Strategy."
 
COMPETITION
 
     The markets for the Company's products are fragmented and highly
competitive. Although none of the Company's competitors is considered dominant,
there are competitors that have significantly greater resources than the
Company, which, among other things, could be a competitive disadvantage to the
Company in securing certain projects. See "Business -- Competition."
 
INTERNATIONAL EXPANSION
 
     The Company's successful expansion into global markets will depend on
numerous factors, many of which are beyond its control. In addition, global
expansion may increase the Company's exposure to certain risks inherent in doing
business outside the United States, including currency fluctuations,
restrictions on the repatriation of profits, compliance with foreign laws and
standards and political risks. Although the majority of the Company's contracts
with respect to international sales to date have been denominated in United
States dollars, no assurance can be made that future contracts will be
denominated in United States dollars; therefore, the Company may be subject to
foreign exchange risks in the future. The Company does not presently hedge
exchange rate fluctuations, but, in the future, may hedge economic exposures.
 
POTENTIAL FOR PRODUCT LIABILITY CLAIMS
 
     Certain of the Company's products are used in handling potentially
hazardous materials. The Company carries insurance in amounts that it considers
adequate. However, catastrophic occurrences at locations where the Company's
products are used could in the future result in significant product liability
claims against the Company. In addition, a number of the Company's products are
used to store regulated substances such as petroleum. The release or leakage of
such substances from these products could also result in liability claims
against the Company.
 
GOVERNMENTAL REGULATION
 
     The Company is subject to various foreign, federal, state and local laws
and regulations relating to the protection of health, safety and the
environment. The Company's business involves environmental and health and safety
management issues typically associated with manufacturing operations. Since
formation of the Company, the Company's cost of complying with such laws and
regulations has not been material. However, future laws and regulations may
become more stringent and may require the Company to incur significant
additional costs. See "Business -- Governmental Regulation."

<PAGE>   11
 
SEASONALITY
 
     The Company's operations are subject to seasonal variations in weather
conditions. Because most of the Company's customers' construction activities
take place outdoors, the number of projects generally declines in the winter
months due to an increase in rainy and cold conditions. In addition, its
customers often schedule the completion of their projects during the summer
months in order to take advantage of the milder weather for the installation of
their equipment and systems. As a result, a disproportionate amount of the
Company's net income, net sales and gross profit has historically been earned
during the first and fourth quarters of the fiscal year. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations."
 
RELIANCE ON PRINCIPAL SUPPLIER
 
   
     The principal raw materials used by the Company in its manufacture of
fiberglass composite USTs are fiberglass and resin. Although resin is available
in adequate supply from a variety of sources, substantial manufacturers of
fiberglass are more limited in number. Because of this limited market supply,
the Company has entered into a supply contract with Owens Corning pursuant to
which the Company has agreed to purchase, and Owens Corning has agreed to
supply, at least 80% of the Company's fiberglass composite UST requirements
through December 31, 1997. The Company has entered into a supply contract with
Owens Corning beginning January 1, 1998 to supply at least 90% of the Company's
fiberglass requirements through December 31, 2000. In addition, this contract
contains certain pricing stabilization terms. As a result of this arrangement,
the Company remains significantly dependent upon Owens Corning to deliver
quality product in accordance with and, as required by, the Company's needs.
    
 
DEPENDENCE ON KEY PERSONNEL
 
     The Company is dependent upon a limited number of key management, technical
and sales personnel. The Company's future success will depend, in part, upon its
ability to attract and retain highly qualified personnel. The Company faces
competition for such personnel from other companies and organizations, and there
can be no assurance that the Company will be successful in hiring or retaining
qualified personnel. The Company does not have written employment agreements
with its officers providing for specific terms of employment, and officers and
other key personnel could leave the Company's employ with little or no prior
notice. The Company's loss of key personnel, especially if the loss is without
advance notice, or the Company's inability to hire or retain key personnel,
could have a material adverse effect on the Company's business, financial
condition or results of operations. The Company does not carry any key man life
insurance.
 
CONTINUED CONTROL BY CURRENT OFFICERS, DIRECTORS AND AFFILIATED ENTITIES
 
   
     Upon completion of this Offering, the Company's current executive officers,
directors and entities affiliated with them will beneficially own, in the
aggregate, approximately 39.4% (36.8% if the Underwriters' over-allotment option
is exercised in full) of the Company's outstanding Common Stock. If they were to
act together, these stockholders would be able to control substantially all
matters requiring approval by the Company's stockholders, including the election
of directors, the adoption or amendment of provisions in the Company's
Certificate of Incorporation or Bylaws and the approval of mergers or other
business combination transactions. Such ownership of Common Stock may have the
effect of delaying, deferring or preventing a change in control of the Company
and may affect the outcome of the voting and other rights of the other
stockholders. See "Principal Stockholders."
    
 
REDEMPTION OF PREFERRED STOCK HELD BY COMPANY DIRECTORS
 
     The Company intends to use a portion of the net proceeds from the Offering
to redeem in full the Company's Series A Preferred Stock. As of September 30,
1997, such redemption amount totaled $1,410,000 (including $210,000 in accrued
and unpaid dividends). Approximately 75% of the Series A Preferred Stock is
beneficially owned by members of the Company's Board of Directors. See "Certain
Transactions" and "Use of Proceeds."
 
                                       10
<PAGE>   12
 
ABSENCE OF DIVIDENDS
 
     The Company anticipates that earnings will be retained for the development
of the Company's business and that no cash dividends will be declared on the
Common Stock in the foreseeable future. See "Dividend Policy."
 
ABSENCE OF PUBLIC MARKET; POSSIBLE VOLATILITY OF STOCK PRICE
 
     Prior to this Offering, there has been no public market for the Common
Stock, and there can be no assurance that an active public market for the Common
Stock will develop or, if one develops, that it will be sustained. The initial
public offering price for the shares of Common Stock offered hereby has been
determined by negotiation between the Company and the representatives of the
Underwriters based upon several factors and may not be indicative of the market
price of the Common Stock after this Offering. See "Underwriting." The market
price of the Common Stock may be volatile and could be adversely affected by
fluctuations in the Company's operating results or the operating results of the
Company's competitors, the failure of the Company's operating results to meet
the expectations of market analysts and investors, changes in environmental or
other laws and regulations, actions by regulatory authorities, developments in
respect of patents or proprietary rights, changes in market analyst
recommendations, general market conditions or other events and factors.
 
EFFECT OF ANTI-TAKEOVER PROVISIONS OF DELAWARE LAW
 
     The Company has not elected to be excluded from the provisions of Section
203 of the Delaware General Corporation Law, which imposes certain restrictions
on transactions between a corporation and "interested stockholders" (as defined
in Section 203). These restrictions could operate to delay or prevent a change
in control of the Company and to discourage, impede or prevent a merger, tender
offer or proxy contest involving the Company. See "Description of Capital
Stock -- Anti-Takeover Provisions of Delaware Law."
 
SHARES ELIGIBLE FOR FUTURE SALE
 
     Future sales of substantial amounts of Common Stock in the public market
following the Offering could adversely affect the market price for the Common
Stock. The 2,184,910 shares of Common Stock outstanding prior to the Offering
are not registered under the Securities Act of 1933, as amended (the "Securities
Act"), and, therefore, are not freely tradable unless subsequently registered
under the Securities Act or exempted from such registration. All of such shares
may be sold pursuant to the requirements of Rule 144 promulgated under the
Securities Act, subject to certain holding period requirements and volume
limitations relating to the sale of securities. In addition, the Company has
adopted a 1996 Incentive Stock Option Plan (the "1996 Plan") and a 1997
Incentive Stock Option Plan (the "1997 Plan") pursuant to which the Company may
grant options to its officers and employees, and shares of Common Stock issuable
upon exercise of options granted under such plans will become available for
future sale in the public market. As of June 28, 1997, there were outstanding
options to acquire 113,190 shares granted under the 1996 Plan, all of which are
currently exercisable. In connection with a merger of Containment Solutions,
Inc., a wholly-owned subsidiary of the Company ("CSI"), with and into the
Company in September 1997, options to acquire an additional 254,643 shares of
Common Stock under the 1996 Plan were issued in exchange for options to acquire
1,400 shares of common stock of CSI, all of which options are immediately
exercisable. Pursuant to the 1997 Plan, the Company has granted, effective as of
the date of this Prospectus, options to acquire 171,030 shares of Common Stock,
of which options to acquire 56,845 shares shall be immediately exercisable. The
Company, all of its executive officers and directors, and certain stockholders
and their affiliates have agreed not to offer, sell, contract to sell or
otherwise dispose of any shares of Common Stock or any right to purchase or
acquire Common Stock without the prior written consent of the Underwriters for a
period of 180 days after the date of this Prospectus. See "Shares Eligible for
Future Sale" and "Underwriting."

DILUTION
 
     The initial public offering price is substantially higher than the net
tangible book value per share of Common Stock. New investors purchasing Common
Stock in this Offering accordingly will experience immediate and substantial
dilution in net tangible book value per share. See "Dilution."
 
POSSIBLE ISSUANCE OF PREFERRED STOCK
 
     In addition to the Common Stock, the Company's Certificate of Incorporation
authorizes the issuance of up to 1,000,000 shares of preferred stock.
Immediately following redemption of all of the shares of the Company's Series A
Preferred Stock with a portion of the net proceeds of the Offering, no shares of
preferred stock of the Company will be outstanding, and the Company has no
current plans to issue any shares of preferred stock. However, because the
rights and preferences for any series of preferred stock may be set by the Board
of Directors in its sole discretion, those rights and preferences may be
superior to the rights of holders of the Common Stock and thus may adversely
affect the rights of holders of Common Stock. See "Description of Capital
Stock -- Preferred Stock."
 
                                USE OF PROCEEDS
 
   
     The net proceeds to the Company from the sale of Common Stock offered
hereby are estimated to be $26.2 million ($30.3 million if the over-allotment
option is exercised in full), at an assumed public offering price of $14.00 per
share and after deducting the estimated underwriting discount and offering
expenses payable by the Company.
    
 
   
     Approximately $16.7 million of the net proceeds to the Company will be used
to repay a portion of the borrowings of the Company incurred under its credit
facility (the "Credit Facility") and $0.2 million for unrelated term debt. The
Credit Facility bears interest per annum at varying rates of LIBOR plus a margin
ranging from 2.75% to 3.00% or the prime rate plus .50%. The Credit Facility has
a five year term. The Credit Facility was used to finance an aggregate of $9.0
million for the Company's acquisitions of LaValley and SEFCO. In addition,
approximately $6.7 million of the net proceeds will be used to repay the
Company's outstanding indebtedness to Owens Corning, which indebtedness was
incurred in connection with the Company's acquisition of the fiberglass
composite UST business of Owens Corning. The indebtedness to Owens Corning bears
interest at 10.0% per annum and is scheduled to mature on December 31, 1999.
Approximately $1.1 million (including accrued interest) of the net proceeds will
be used to repay the Company's outstanding indebtedness to Praxair, Inc., which
indebtedness was incurred in connection with the acquisition of Ershigs. The
indebtedness to Praxair, Inc. bears interest at a rate of 10.0% per annum and is
scheduled to mature in February 1998. A portion of the proceeds equal to
approximately $1.4 million will be used to redeem all of the shares of the
Company's Series A Preferred Stock (including accrued and unpaid dividends
through the date of redemption). The Company's Directors beneficially own
approximately 75% of the Series A Preferred Stock. The remaining net proceeds,
if any, are intended to be used by the Company for general working capital
purposes. See "Business -- Business Strategy."

                                DIVIDEND POLICY
 
     The Company has never paid cash dividends on its Common Stock. The Company
currently expects that it will retain future earnings for use in the operation
and expansion of its business and does not anticipate paying any cash dividends
in the foreseeable future. With respect to dividends for the Company's Series A
Preferred Stock, see "Use of Proceeds."
 
                                 CAPITALIZATION
 
   
     The following table sets forth the capitalization of the Company as of
September 27, 1997, on a (i) historical basis, (ii) pro forma basis to give
effect to the acquisitions of LaValley and SEFCO, and (iii) pro forma as
adjusted basis to give effect to the sale of Common Stock offered hereby and
application of the net proceeds therefrom. See "Use of Proceeds." This
information is qualified in its entirety by, and should be read in conjunction
with, the Consolidated Financial Statements and Pro Forma Condensed Consolidated
Financial Statements of the Company appearing elsewhere in this Prospectus.

                                    DILUTION
 
   
     Dilution is the reduction in the value of a purchaser's investment in
Common Stock measured by the difference between the purchase price per share and
the net tangible book value per share of the Common Stock after the purchase.
The net tangible book value per share of the Common Stock represents the net
tangible book value of the Company, its total assets less its total liabilities
and intangible assets (consisting primarily of goodwill), divided by the number
of shares of Common Stock outstanding. At September 27, 1997, the net tangible
book value of the Common Stock before giving effect to the Offering (assuming an
initial public offering price of $14.00 per share) was $(1.32) per share. After
giving effect to the sale of the shares of Common Stock offered in the Offering
and after deducting estimated underwriting discounts and offering expenses of
approximately $3.2 million, the net tangible book value of the Company at
September 27, 1997 would have been approximately $5.44 per share. This
represents an immediate dilution of $8.56 per share to new investors and an
increase in the net tangible book value of approximately $6.76 per share to
existing stockholders, as illustrated by the following table:

    from or as a substitute for net income or cash flow measures prepared in
    accordance with generally accepted accounting principles or as a measure of
    a company's profitability or liquidity. In addition, EBITDA may not be

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
     The following discussion should be read in conjunction with the "Selected
Consolidated Financial Data" and the Company's Consolidated Financial Statements
included elsewhere in this document.
 
OVERVIEW
 
   
     Since inception in 1994, the Company has acquired five businesses. Due to
the magnitude of these acquisitions and the integration of the acquired
operations with the Company's existing businesses, results of operations for
prior periods are not necessarily comparable with or indicative of current or
future periods. Each of the acquisitions has been accounted for under the
purchase method of accounting. Accordingly, the acquired businesses have been
included in the Company's results of operations from the date of acquisition.
    
 
     The Company was formed in December 1994 to acquire certain assets and
assume certain liabilities of the fiberglass composite UST business of Owens
Corning, including five manufacturing facilities. The purchase price was $16.6
million, consisting of $5.6 million in cash, $9.3 million in notes payable and
approximately $1.7 million in acquisition costs. The Company significantly
restructured the operations of this business at the time of purchase. Two of the
five manufacturing facilities of the business were closed, resulting in a
significant reduction in fixed manufacturing overhead. Operating costs were
significantly reduced throughout the Company, in part through the elimination of
approximately 20 management positions. The Company sold the two closed and idle
manufacturing facilities in fiscal 1996 for $1.5 million in cash (before selling
expenses) and an $850,000 note receivable.
 
     In October 1995, the Company acquired certain assets and assumed certain
liabilities of Hoover, a manufacturer of steel rectangular ASTs. The purchase
price of $5.5 million consisted of $5.4 million in cash and acquisition costs of
approximately $100,000. The Company eliminated certain operating costs through
the sharing of certain general and administrative functions within the acquired
businesses. The addition of the steel rectangular AST product line enabled the
Company to offer a broader line of containment products and to expand its
customer base. These two businesses form the Company's Containment Products
Group.
 
   
     The Company has modernized and expanded its manufacturing capabilities for
its steel rectangular AST business through construction of a new,
built-for-purpose facility, consolidating three manufacturing and administrative
office locations in Maryland. Expenses associated with this consolidation
impacted fiscal 1997 results; however, the Company believes this move has
positioned the Company to more effectively and efficiently meet market demand
beyond fiscal 1997.
    
 
     In February 1997, the Company acquired Ershigs, a manufacturer of
engineered FRP products, as the first of the Company's Engineered Products
Group. The $6.1 million purchase price consisted of $5.0 million in cash, $1.0
million in a note payable and acquisition costs of approximately $80,000.
Substantial operational changes were made upon the purchase of Ershigs,
including the closing of one of Ershigs' three manufacturing plants and the
restructuring most of Ershig's sales, general and administrative functions,
which enabled the Company to enhance profitability.
 
   
     In October 1997, the Company acquired SEFCO for approximately $4.9 million
in net cash and $100,000 in direct acquisition costs. SEFCO is a manufacturer of
engineered field-erected aboveground steel tanks. In October 1997, the Company
also acquired LaValley for $3.9 million in cash and $100,000 in direct
acquisition costs. LaValley manufactures engineered FRP products. LaValley and
SEFCO, together with Ershigs, form the Company's Engineered Products Group.
    
 
   
     The acquisitions of LaValley and SEFCO accounted for $17.9 million of the
Company's pro forma 1997 net sales of $104.9 million.

fiscal 1995, 1996, 1997 and the three month periods ended September 28, 1996 and

THREE MONTHS ENDED SEPTEMBER 27, 1997 COMPARED WITH THREE MONTHS ENDED SEPTEMBER
28, 1996
    
 
   
     Net sales increased $4.3 million, or 24%, to $22 million in the first
quarter of fiscal 1998 from $17.7 million in the same quarter of fiscal 1997.
Most of the increase ($4.0 million) was attributable to the inclusion of Ershigs
sales in the fiscal 1998 period following the February 1997 acquisition by the
Company. The Containment Products Group sales increased 1.6% from the prior year
period.
    
 
   
     Gross profit increased $1.1 million, or 29%, to $4.8 million in the fiscal
1998 period from $3.7 million in fiscal 1997. Most of the increase ($1.0
million) was related to the inclusion of Ershigs in the fiscal 1998 period at a
25.7% margin. Gross margin for the Company increased to 22% from 21.2% in the
prior year quarter due to Ershigs' higher margin products. The Containment
Products Group margin of 21.1% in the fiscal 1998 period was slightly lower than
the 21.2% margin in the prior year quarter.
    
 
   
     Selling, general and administrative expenses for the fiscal 1998 first
quarter totaled $3.8 million (17.4% of revenues), compared with $2.8 million
(15.7% of revenues) for the prior year quarter. Most of the increase ($835,000)
was attributable to the inclusion of Ershigs in the fiscal 1998 period. The
remainder of the increase was attributable primarily to higher sales and
marketing expenses in the Containment Products Group.
    
 
   
     The Company recognized a $2.3 million non-recurring compensation charge in
the first quarter of fiscal 1998 due to the exchange of subsidiary stock options
for Denali stock options.
    
 
   
     Interest expense for the fiscal 1998 period increased $109,000 to $607,000
from $498,000 in the prior year quarter. The increase was due to increased debt
resulting from the February 1997 Ershigs acquisition.
    
 
   
     The Company's provision for income taxes, which includes the effects of the
non-recurring charge for compensation expense, differs from the U.S. statutory
rate of 34% due to the non-recurring compensation charge being non-deductible
for income tax purposes. In addition, the Company's provision for income taxes
differs from the U.S. statutory rate due to state income taxes and other
permanent differences.
    
 
  FISCAL 1997 COMPARED WITH FISCAL 1996
 
     The Company's results of operations for fiscal 1997 were greatly impacted
by the inclusion of 17 weeks of results of Ershigs, which was acquired in
February 1997, and the inclusion of the results of Hoover, which was acquired in
October 1995, for a full fiscal year as compared to 35 weeks reflected in fiscal
1996.
 
   
     Net sales for fiscal 1997 increased $17.7 million, or 33%, to $71.1
million, from $53.4 million in fiscal 1996. This increase primarily resulted
from $6.3 million of sales at Ershigs and a $10.0 million increase in sales at
Hoover.
    
 
   
     Gross profit increased $4.0 million, or 41%, to $13.8 million in fiscal
1997 from $9.8 million in fiscal 1996. Gross profit margins were 19.5% and 18.4%
for fiscal 1997 and 1996, respectively. The Containment Products Group's gross
profit margin improved to 19.6% in fiscal 1997 as compared to 18.4% in fiscal
1996. This improvement resulted primarily from a lower cost of fiberglass and
resin used in the manufacture of fiberglass composite USTs. The gross profit
margin for the Company's Engineered Products Group was 18.2% in fiscal 1997.
    
 
     Selling, general and administrative expenses increased $2.3 million, or
24%, to $11.9 million in fiscal 1997 from $9.6 million in fiscal 1996. This
increase was attributable to the inclusion of the Ershigs business and a full 12
months of the Hoover business as discussed above. This increase was partially
offset by savings resulting from a reduction and consolidation of workforce for
the Company's fiberglass composite UST business. Selling, general and
administrative expenses decreased as a percentage of net sales from 18.0% in
fiscal 1996 to 16.7% in fiscal 1997.
 
     Interest expense in fiscal 1997 was $2.1 million compared to $1.8 million
in fiscal 1996. The increase was primarily a result of increased borrowings
required to finance the purchase of Ershigs and a full year of interest for
borrowings in connection with the acquisition of Hoover.
 
                                       19
<PAGE>   21
 
     Other income increased $392,000 to $598,000 in fiscal 1997 from $206,000 in
fiscal 1996. This increase resulted primarily from a gain on the sale of idle
equipment to international licensees for the manufacture of fiberglass composite
USTs.
 
     The increase in income tax expense for fiscal 1997 compared to fiscal 1996
resulted from higher pre-tax earnings related to increased profitability of the
Containment Products Group.
 
  FISCAL 1996 COMPARED WITH FISCAL 1995
 
     The Company was incorporated on December 19, 1994. Consequently, fiscal
1995 represented the results of operations for the 28-week period from December
19, 1994 through July 1, 1995.
 
     Net sales increased $35.6 million, or 200%, to $53.4 million in fiscal 1996
from $17.8 million in fiscal 1995. The increase in net sales was directly
attributable to the increased reporting period from 28 weeks to 52 weeks for the
fiberglass composite UST business acquired from Owens Corning in December 1994,
and to the inclusion of 35 weeks for the Hoover business, acquired in October
1995, reflected in fiscal 1996 whereas there were none in fiscal 1995.
 
   
     Gross profit increased $5.5 million, or 128%, to $9.8 million in fiscal
1996 from $4.3 million in fiscal 1995. Gross profit margins were 18.4% and 24.3%
for fiscal 1996 and 1995, respectively. The decrease in margin was primarily
attributable to increased prices for fiberglass and resin used in the
manufacture of the fiberglass composite UST products.
    
 
     Selling, general and administrative expenses increased $5.8 million, or
153%, in fiscal 1996 to $9.6 million from $3.8 million in fiscal 1995. Selling,
general and administrative expenses as a percentage of net sales decreased to
18.0% for fiscal 1996 compared to 21.2% for fiscal 1995 primarily due to the
Company's reduction and consolidation of its workforce.
 
     Interest expense in fiscal 1996 was $1.8 million compared to $671,000 in
fiscal 1995. Approximately $300,000 of the increased interest expense in 1996
was attributable to increased borrowings arising from the acquisition of Hoover.
The remaining increase resulted from the inclusion of a full year of interest
expense for the Company. In addition, the level of borrowings for the fiberglass
composite UST business increased $1.2 million during fiscal 1996 to fund general
working capital requirements.
 
   
LIQUIDITY AND CAPITAL RESOURCES
    
 
   
     Working capital at June 28, 1997, was $8.0 million, as compared to $5.6
million at June 29, 1996. Cash provided by operating activities was $625,000 for
fiscal 1997 and cash used in operating activities was $109,000 in fiscal 1996.
The improvement in cash provided by operating activities resulted primarily from
a $1.2 million improvement in net income from an $834,000 loss in fiscal 1996 to
a $317,000 profit in fiscal 1997. Capital expenditures totaled $600,000 and
$942,000 in fiscal years 1997 and 1996, respectively. Working capital at
September 27, 1997, was $6.9 million as compared to $8.3 million at September
28, 1996. Cash provided by operating activities was $2.1 million for the three
months ended September 27, 1997 and cash used in operating activities was $1.5
million for the three months ended September 28, 1996. The improvement in cash
provided by operating activities resulted primarily from changes in working
capital. Capital expenditures totaled $208,000 and $71,000 for the three months
ended September 27, 1997 and September 28, 1996, respectively. The Company
anticipates that its operating cash flows and available line of credit after
application of the net proceeds of this Offering will be adequate to fund future
capital commitments and working capital requirements for the next 12 months. The
Company estimates that its capital expenditures for fiscal 1998 will be
approximately $1.2 million.
    
 
   
     As further described in Note 7 to the Denali Incorporated Consolidated
Financial Statements, the Company refinanced its credit facilities in October
1997. In connection with the extinguishment of its old credit facility upon
funding of a new credit facility in October 1997, the Company paid prepayment
penalties of $323,000. In addition, the Company charged to expense unamortized
debt origination costs of $295,000 in October 1997. These charges will be
recognized in the Company's consolidated financial statements as an
extraordinary loss, net of tax, of $383,000 in the quarter ended December 27,
1997.
    
 
                                       20
<PAGE>   22
 
   
     The Company's Credit Facility with its principal lender provides for
revolving lines of credit and secured term loans of up to an aggregate of $29.7
million. As of November 1, 1997, the Company had outstanding indebtedness of
$10.7 million under the term loans and $11.6 million under the revolving lines
of credit. Borrowings under this Credit Facility are secured by liens on
substantially all of the Company's assets. See Note 7 of Notes to the
Consolidated Financial Statements for certain information regarding the Credit
Facility. The Credit Facility bears interest per annum at varying rates of LIBOR
plus a margin ranging from 2.75% to 3.00% or the prime rate plus .50%. The
Credit Facility has a five year term.
    
 
   
     In connection with its acquisition of the fiberglass composite UST business
of Owens Corning, the Company issued to Owens Corning a $7.5 million note which
bears interest at an annual rate of 10.0% and matures on December 31, 1999, and
is to be repaid with a portion of the net proceeds of this Offering. The Company
anticipates that the early repayment of this indebtedness to Owens Corning will
result in extraordinary gains, net of tax, of approximately $416,000 in the
second quarter of fiscal 1998 and $242,000 in the fourth quarter of fiscal 1998.
The extraordinary gain in the fourth quarter is contingent on minimum purchases
through June 1998 required by the Company under the Owens Corning supply
agreement.
    
 
     The Company assumed $1.0 million in Industrial Revenue Bonds ("IRBs") in
connection with its acquisition of the Owens Corning fiberglass composite UST
business. The IRBs bear interest at 9.9% per annum, mature in February 2001 and
are secured by the Company's Conroe, Texas manufacturing facility.
 
   
     The Company's capital requirements primarily relate to acquisitions of
businesses in the critical fluids handling industry. The Company has made cash
payments net of cash acquired for acquisitions of approximately $26.5 million in
the aggregate since inception in December 1994. The source of this cash
primarily has been bank debt along with proceeds from the sale of idle assets
and use of net working capital. The Company's acquisition program will require
significant additional capital. The Company intends to seek additional capital
as necessary to fund such acquisitions through one or more funding sources that
may include borrowings under the Credit Facility, or offerings of debt and/or
equity securities of the Company. Cash provided by operating activities may also
be used to fund a portion of future acquisitions. Although management believes
that the Company will be able to obtain sufficient capital to fund acquisitions,
there can be no assurances that such capital will be available to the Company at
the time it is required or on terms acceptable to the Company.
    
 
QUARTERLY RESULTS AND SEASONALITY
 
     The Company has experienced significant fluctuations in its quarterly
results of operations. These fluctuations have been attributable to timing of
acquisitions and seasonality. The Company's quarterly operating results are
affected by the annual construction season slowdown resulting from winter
weather especially in the period December through March. The fiberglass
composite UST business is especially impacted during the winter months. The
following table represents the Company's selected unaudited quarterly
consolidated statements of operations for each quarter in fiscal 1996 and 1997:

                                    BUSINESS
THE COMPANY
 
   
     The Company is a rapidly growing provider of products and services for
handling critical fluids, which are fluids that are economically valuable or
potentially hazardous to the environment. The Company believes that it is a
leading manufacturer of fiberglass composite USTs, steel rectangular ASTs and
fiberglass reinforced composites for handling corrosive fluids. Critical fluids
handling products and services are used in a wide variety of applications,
including in retail petroleum marketing and in petroleum, chemical, pulp and
paper, electric power and other industrial process plants.
    
 
     BACKGROUND
 
     The Company was formed in 1994 to acquire the fiberglass composite UST
business of Owens Corning. Initially, the Company focused its efforts on
improving profitability, improving responsiveness to customers and developing
new products. The Company's management also realized that the critical fluids
handling industry was highly fragmented and that there would be significant
opportunities to consolidate the industry.
 
   
     In October 1995, the Company acquired Hoover, a manufacturer of steel
rectangular ASTs, and, in February 1997, the Company acquired Ershigs, a
manufacturer of engineered FRP products for handling corrosive fluids.
    
 
   
     In October 1997, the Company acquired LaValley, another manufacturer of FRP
products, and SEFCO, a fabricator of engineered field-erected steel tanks.
    
 
   
     Prior to forming the Company, the Company's Chairman and Chief Executive
Officer, Stephen T. Harcrow, was President of EnviroTech, a business unit of
Baker Hughes Incorporated, from 1988 to 1993. EnviroTech was a manufacturer of
equipment for process industries. During Mr. Harcrow's tenure as President,
EnviroTech grew through the acquisition of manufacturers of fluid separation,
pumping and measurement products, with annual revenues increasing from
approximately $365 million up to $680 million. Since the Company's formation,
five other former employees of EnviroTech have joined the Company as executive
officers.
    
 
     PRODUCTS AND SERVICES
 
     Containment Products. The Company's Containment Products Group specializes
in the manufacture of fiberglass composite USTs and rectangular steel ASTs. The
Company's fiberglass composite USTs, manhole products and oil/water separators
are marketed under the Fluid Containment tradename and its steel rectangular
ASTs are marketed under the Hoover and LubeCube(R) tradenames.
 
   
     Engineered Products. The Company's Engineered Products Group specializes in
providing custom engineered FRP products and engineered metal products for the
pulp and paper, power, chemical, water and wastewater and other process
industries. The Company markets its engineered FRP products under the Ershigs
tradename and believes that it is a leading domestic provider of engineered FRP
products for corrosion resistant applications. SEFCO is an integrated
manufacturer of engineered field-erected steel tanks and accessories for use in
the water and wastewater, agrochemical and petroleum industries. This group
focuses its operations on complex projects, where custom engineering and special
manufacturing expertise are critical.
    
 
     BUSINESS STRATEGY
 
     The Company's objective is to become the leading provider of a broad range
of products and services for handling critical fluids through strategic
acquisitions and internal growth. The Company believes that the fragmented
nature of the critical fluids handling industry, which is comprised of many
companies with limited product ranges or serving limited geographic areas, will
provide continued acquisition and internal growth opportunities. The Company
also believes that these opportunities provide the Company with the ability to
offer a comprehensive range of specialized solutions for meeting customers'
critical fluids handling needs.

<PAGE>   24
 
   
     Acquisition Strategy. Since its founding in 1994, the Company has completed
five acquisitions. The Company's net sales have grown from approximately $17.8
million for fiscal 1995 (a 28-week period ended July 1, 1995) to $71.1 million
for fiscal 1997. Pro forma net sales for fiscal 1997 were approximately $104.9
million, including approximately $17.9 million with respect to the recent
acquisitions of SEFCO and LaValley. Net loss for fiscal 1995 was $43,000 and
increased to net income of $317,000 for fiscal 1997 and was $595,000 for pro
forma first quarter fiscal 1998, excluding a $2.3 million non-recurring
compensation charge. In addition, EBITDA (as defined in "Summary Consolidated
Financial Data") increased from $981,000 for fiscal 1995 to approximately $3.9
million for fiscal 1997 and was $2.3 million for pro forma first quarter fiscal
1998. Key elements of the Company's acquisition strategy include:
    
 
     - Develop a Comprehensive Range of Products and Services. The Company's
       existing products offer a variety of containment and engineered materials
       solutions for handling critical fluids. The Company intends to broaden
       its product lines to introduce additional critical fluid separation and
       measurement products. The Company believes that the ability to offer a
       comprehensive range of critical fluids handling products and services
       will be a competitive advantage.
 
   
     - Expand Within Existing Markets. The Company intends to expand its product
       offerings within the geographic markets it currently serves. For example,
       the SEFCO acquisition is expected to expand the Company's engineered
       product capabilities into the field fabrication of tanks.
    
 
   
     - Penetrate New Geographic Markets, Including International Markets. The
       Company believes that it can expand its operations that are regional in
       nature throughout the United States and internationally. For example, the
       acquisition of LaValley is expected to strengthen the Company's market
       position in the Gulf Coast region for the Company's engineered products.
       In addition, the Company intends to pursue license agreements for the
       international manufacture of certain products.
    
 
     Internal Growth Strategy. The Company is also focused on expanding the
scope and profitability of each of the businesses it acquires. Key elements of
this growth strategy are:
 
     - Promote Internal Growth through a Decentralized Structure. The Company
       employs a decentralized management and operational structure to
       capitalize on market knowledge, product expertise, name recognition and
       customer relationships.
 
     - Reduce Product and Administrative Costs. The Company's consolidation
       effort has led to raw materials purchasing economies, manufacturing
       efficiencies, increased sales coverage and product transportation cost
       reductions. In addition, the Company has improved operating margins by
       consolidating administrative functions such as finance, insurance and
       employee benefits.
 
     - Develop New Products. The Company utilizes the technological expertise,
       market knowledge and customer relationships of the businesses it acquires
       to develop new products. For example, as a result of the Company's
       development efforts, sales of oil/water separators and FRP manhole
       products have increased from approximately $500,000 for fiscal 1995 to
       more than $2.3 million for fiscal 1997.
 
     - Utilize Available Manufacturing Capacity. The Company also believes new
       products, acquired businesses and growth of current product net sales
       will increase manufacturing and facility utilization, contributing to
       further increases in profitability.

OPERATIONS
    
 
     The Company is organized to capitalize on focused core competencies and
expertise. Its operations are currently split into two groups: the Containment
Products Group and the Engineered Products Group. As part of the Company's
growth strategy, the Company also anticipates creating two additional product
groups to include critical fluid separation and measurement product lines. For a
discussion of certain industry segment data, see Note 17 of Notes to the
Consolidated Financial Statements.
 
CONTAINMENT PRODUCTS
 
     The Containment Products Group of the Company focuses its operations on the
manufacture of fiberglass composite USTs and steel rectangular ASTs.
 
   
     FIBERGLASS COMPOSITE UNDERGROUND STORAGE TANKS. The Company believes that
it is a leading manufacturer of fiberglass composite USTs and markets its
products under the Fluid Containment tradename. The Company manufactures and
markets single wall and double wall fiberglass composite USTs; leak detection
systems; oil/water separators; ReTank(R) retrofit systems; storage tank anchor
systems; and fiberglass manhole and wetwell products. The Company is the
successor to the fiberglass composite UST business of Owens Corning, which
invented the fiberglass composite UST.
    
 
     Prior to the Company's acquisition of the tank business of Owens Corning,
Owens Corning completed over 235,000 fiberglass composite UST installations
during a 30-year period, and helped write and maintain the Underwriters'
Laboratory ("UL") 1316 specification. Since the acquisition, the Company has
completed almost 15,000 installations of its own fiberglass composite UST
products. The Company has a comprehensive training program for installers of the
Company's products. The Company also has experienced field service groups
located in California, Texas, Indiana, Pennsylvania, Florida and South Carolina
that support both the installers and their customers.
 
     Each fiberglass composite UST comes with a 30-year corrosion warranty and
is guaranteed not to rust. The corrosion resistant nature of fiberglass
reinforced composite is the chief advantage the Company's fiberglass composite
USTs have in the market. The Company continues to strengthen its position in the
UST industry through research and development and a continual upgrading of its
manufacturing processes and investment in its employees.
 
   
     Market. The Company believes that its fiberglass composite UST business is
growing primarily because of increased geographic coverage programs by petroleum
marketers and increased scope of service station offerings by the major oil
companies. Most of these fiberglass composite UST sales are for new locations
and developments and not for replacement and rehabilitation programs. An
important market for the Company is the newer, larger stations, known as
"super-c" stores, that combine the traditional self-service station with a fast
food store and a convenience store. According to an August 1995 report of the
Fiberglass Tank and Pipe
    
 
                                       24
<PAGE>   26
 
Institute, an industry organization with principal offices located in Houston,
Texas, over 90% of all major petroleum marketing companies in the United States,
which includes all of the major integrated oil companies, specify fiberglass
composite USTs at all of their new construction sites. The Company believes that
growth in this area will continue to expand.
 
     The Environmental Protection Agency ("EPA") has established certain minimum
requirements for UST systems installed before December 22, 1988. A majority of
the USTs currently in place in the United States were installed prior to that
date. The EPA requirements call for spill protection, overfill protection and
corrosion protection. A site with a UST of this age must either (1) add spill,
overfill and corrosion protection by December 22, 1998; (2) close the existing
UST by December 22, 1998; or (3) replace the closed existing UST with a new UST
meeting current regulatory standards. The EPA has announced that it intends to
enforce these minimum requirements and that failure of UST owners to adhere to
these requirements by the specified date could result in the UST owner being
cited for violations and fined. To date, the Company's fiberglass composite UST
business does not appear to have been significantly impacted by the
implementation of these EPA requirements and there can be no assurance that
these requirements ultimately will be enforced by the EPA and, if enforced, that
the Company will realize an increase in its fiberglass composite UST net sales
as a result of such enforcement activity.
 
     Competition. The UST market is highly competitive and fragmented, with
entrants from both steel tank suppliers and another major fiberglass composite
UST supplier. Steel tanks account for a majority of the United States UST
market, in terms of net sales. The remainder of this market is divided fairly
evenly between two fiberglass composite UST suppliers, the Company and Xerxes,
Inc., a company headquartered in Minneapolis, Minnesota that has six
manufacturing facilities in the United States. Although steel USTs are less
expensive than fiberglass composite USTs, fiberglass composite USTs are not
subject to corrosion and do not expose the customer to corrosion leaks and
related environmental problems. When determining which product to acquire, one
of these two factors will generally control the purchase decision. Although over
100 manufacturers of UL listed steel USTs are located in the United States, most
of these manufacturers are small, independent operations. Several of the UST
manufacturers, however, are divisions or subsidiaries of larger corporations
with financial resources greater than that of the Company. Transportation costs
are important in the overall cost of product for this market. As a result, local
manufacturers have a distinct advantage of shipping products to the customer.
The Company believes that its quality of manufacturing, manufacturing control,
product design, testing procedures, history of performance and reliability,
delivery capability, customer responsiveness and experienced personnel are
competitive advantages in the UST market.
 
     Marketing and Customers. The Company takes a multifaceted approach to
marketing its fiberglass composite UST products and services. The Company's
sales staff primarily supports an extensive network of Petroleum Equipment
Industry ("PEI") distributors and contractors. For significant national
accounts, i.e. a major oil company, the Company generally sells directly to the
end user, filling orders through its distributors and contractors. The Company's
largest fiberglass composite UST customers are super-regional distribution
houses and major oil companies; however, the overall customer base is diverse,
with no one customer accounting for more than 4% of the Company's fiberglass
composite UST net sales in fiscal 1997. The Company's top eight fiberglass
composite UST customers, a mix of PEI distributors and major oil companies,
accounted for 22% of the Company's fiberglass composite UST net sales in fiscal
1997. The Company has license agreements with companies outside the United
States to produce fiberglass composite USTs using the Company's technology and
continues to expand this presence.
 
   
     STEEL RECTANGULAR ABOVEGROUND STORAGE TANKS. The Company believes that it
is a leading manufacturer of steel rectangular ASTs. The AST market includes
both rectangular and cylindrical configurations and is defined by the Company as
steel constructions intended for stationary aboveground storage of flammable and
combustible liquids at atmospheric pressure. Part of this market includes tanks
called vault tanks which are constructed with an insulation system that is
designed to reduce the heat transferred to the primary tank in the event the
construction were to be exposed to a hydrocarbon pool fire. The term "AST" also
refers to tanks manufactured and then transported as a completed unit to the
customer. For the purposes of this Prospectus, the term "AST" does not include
tanks certified as "large aboveground storage tanks" by the American
    
 
                                       25
<PAGE>   27
 
Petroleum Institute (tanks with a capacity in excess of 1,000 barrels). The
Containment Products Group does not manufacture these large aboveground storage
tanks.
 
     The Company sells its steel rectangular AST products under the Hoover name
and has two primary product lines: lubricant tanks (Lube Cube(R)) and vault
tanks. Lube Cube(R) tanks are designed and built to hold oil and waste oil
products in a service station-type environment, are available in standard sizes
up to 12,000 gallons and may be custom designed according to the customer's
needs. All Lube Cubes(R) meet NFPA (National Fire Protection Association)-30 for
storage of flammable and combustible liquids and are manufactured, tested and
labeled according to UL-142 as well as Underwriters' Laboratories of Canada.
 
     The Company's vault tanks, sometimes referred to as insulated tanks, are
steel rectangular ASTs designed to hold highly combustible fuels, whether
gasoline, diesel or other. These tanks meet all national fire code requirements
for "fire rated" ASTs. Vault tanks are labeled according to UL-2085 "Protected
Secondary Containment" for ASTs containing flammable liquids. The Company's
vault tanks utilize a patented double wall tank design with insulating material
surrounding the inner tank. A pressure testable second steel tank surrounds the
insulating material, providing protection to the material and secondary leak
containment for the primary tank. In addition to the UL listed tanks, the
Company also offers factory-installed equipment packages, including steps,
platforms, pumps and electronics for fuel dispensing, standby generators, used
oil and lubricating oil.
 
     Market. The Company believes that its base market for its steel rectangular
AST products is growing. The Lube Cube(R) tank market is tied to the growth in
number and size of quick-change oil stations and full service centers for auto
repair. The vault tank business continues to grow as the market accepts
aboveground alternatives to historically underground storage. The vault tank
product line has experienced some sales activity associated with the EPA tank
upgrade deadline described above; however, the Company believes that its steel
rectangular AST growth will be driven by factors other than regulatory
compliance.
 
     Competition. The Company's steel rectangular ASTs are sold in highly
fragmented and competitive markets. Most AST manufacturers produce cylindrical
steel tanks that compete against the Company's steel rectangular AST products.
Over 240 steel AST manufacturers operate in North America, and over 75 of these
companies manufacture vault tanks. Several competitors of the Company are
divisions or subsidiaries of larger companies with financial and other resources
greater than those of the Company. However, the Company believes that the
majority of its competitors in this market are local, individually owned
manufacturing facilities because of the cost to transport ASTs significant
distances. The Company believes that it is the only national manufacturing
company in this market, operating facilities in Maryland and California and
having subcontracting agreements with quality manufacturing companies in
Virginia, North Carolina, Indiana, Kansas, Nebraska, Idaho, Maryland and New
York. Almost half of the Company's steel rectangular AST net sales relate to
products manufactured by its subcontractors, providing the flexibility to
cost-effectively service its customers. The Company's national presence reduces
transportation costs for products relative to single plant competitors that
compete on a national basis. However, local manufacturers have a competitive
advantage in transportation costs. The Company believes that its broad product
lines, product design, delivery capability, customer responsiveness and
experienced personnel are competitive advantages in the AST market.
 
     Marketing and Customers. The Company uses its sales staff and outside sales
representative to market its steel rectangular AST products to the end-user
through a network of PEI distributors and contractors. The customer base for its
steel rectangular ASTs is broad, having over 900 accounts. In fiscal 1997, no
customer accounted for greater than 4% of the Company's steel rectangular AST
net sales except for the United States government, which accounted for
approximately 8% of the Company's steel rectangular AST net sales.
 
     ENGINEERED PRODUCTS
 
   
     The Company's Engineered Products Group believes that it is a leading
manufacturer of engineered FRP products for corrosion resistant applications and
engineered field-erected steel tanks for the municipal and industrial markets.
    
 
                                       26
<PAGE>   28
 
     ENGINEERED COMPOSITE PRODUCTS. The Company markets its engineered FRP
products for corrosion resistant applications under the Ershigs name and is a
professional engineering, manufacturing and construction organization that has
been serving the industry since 1921. The Company acquired Ershigs in February
1997. The Company focuses its operations in corrosion resistant applications on
complex projects, where engineering and manufacturing expertise is critical. The
Company designs, manufactures and installs stacks, stack liners, scrubbers,
tanks, abrasion resistant pipe and fittings, retention towers and various types
of engineered systems. For large diameter structures, the Company employs a
proven on-site manufacturing process that eliminates most handling,
transportation and remote access concerns. The Company has produced seamless
tanks in excess of 100 feet in diameter using this method.
 
     Market. The Company serves a variety of industries, including pulp and
paper, power, chemical, water and wastewater and other process industries. The
Company's business is affected by these industries' capital expenditures, which
are driven primarily by economic conditions as they relate to the need for new
construction, expansion or rehabilitation. Key drivers that the Company believes
will affect growth in this area are the implementation of new, more stringent
EPA emission regulations for the pulp and paper industry and for the power
industry and increasing prices of alternative materials, particularly corrosion
resistant grades of stainless steel. Certain capital expenditures in these
industries have been postponed pending the release of the new EPA regulations.
The EPA has announced that such regulations should be published by November
1998; however, there can be no assurance that such regulations will be released
by that date and, even if published by then, that the Company's corrosion
resistant engineered products net sales will experience growth as a result of
the implementation of such regulations.
 
     Competition. The Company participates in a highly fragmented market where
it believes that most of its competitors are small regional fabrication
businesses. Field-erection capabilities and the Company's performance warranty
are believed by the Company to provide competitive advantages. RTP ("Reinforced
Thermoset Plastics")-1 certification is a competitive advantage in this market
and the Company is RTP-1 certified. RTP-1 certification is earned through
process audits administered by the American Society of Mechanical Engineers.
Such certification denotes quality manufacturing practices, adherence to
standardized procedures and a process to qualify material and tank design
according to prescribed tests of physical properties. The Company believes that
its engineering capabilities, quality reputation, history of performance and
effective customer service are competitive advantages in the engineered FRP
products market.
 
     Marketing and Customers. The Company generally sells its engineered FRP
products through a combination of direct field sales and a sales representative
network. The scope of the work performed by the Company is large in nature and,
unless characterized as a special situation, has long lead times to order. The
experienced sales force works closely with the customer in designing the correct
solution for the customer's need. The customer base of the Company varies from
year to year due to the project-oriented nature of the Company's work in this
area. The Company has also entered into a license agreement with an
international company to provide technology, equipment and expertise.
 
   
     ENGINEERED METAL PRODUCTS. In October 1997, the Company acquired SEFCO, a
manufacturer of engineered field-erected steel tanks and accessories for use in
the municipal, agrochemical and petroleum industries. The Company is vertically
integrated with services ranging from engineering design, materials procurement,
fabrication, site preparation, piping, foundation work, erection and painting,
both in shop and on site. The Company also offers tank inspection, maintenance
and repair and operates primarily in Oklahoma, Missouri, Arkansas and Kansas.
    
 
     Market. The Company participates in the municipal and industrial markets.
These markets are dependent on customers' needs for new installations,
expansions and rehabilitation of existing facilities. The municipal market is
less cyclical than the industrial segment, and it historically represents
approximately 70% of the Company's engineered metal products net sales. The
Company deals with a select group of industrial customers that are primarily in
the chemical and petrochemical industries. In the region served, the Company
believes that both of these markets are growing.
 
     Competition. The market in which the Company competes for engineered metal
products is highly competitive and characterized by numerous small competitors
in the municipal market and several large,
 
                                       27
<PAGE>   29
 
public companies with financial resources greater than those of the Company in
the industrial market. The Company believes that it is able to achieve
differentiation by taking advantage of the levels of service, reliability and
quality control afforded by vertical integration. Generally, the Company's
competitors in the engineered metal products industry are reliant on outside
suppliers and local contractors to fulfill the complete scope of projects. The
Company believes that this difference between the Company and its competitors
provides the Company major advantages in bidding, quality control and
scheduling.
 
     Marketing and Customers. Marketing activities in this area are limited. The
Company's engineered metal product customer focus has been the municipal water
industry. It has been the Company's experience that most municipal projects are
awarded on a price-based bid with attendant requirements for bid bonding. The
municipal customers are generally broad based with no known customers
representing over 20% of the Company's business activity in this area.
Alternatively, the Company believes that industrial client contracts are awarded
based upon a combination of bids and private negotiations. The Company believes
that it can differentiate itself in all engineered metal product markets in its
region as a result of the extensive services it offers through vertical
integration of its services.
 
FACILITIES
 
     The Company operates facilities throughout the United States and considers
them to be in good operating condition and adequate for their present uses. The
Company believes that it has sufficient capacity to meet its current and
anticipated manufacturing requirements for its operations. The Company owns a
facility in Gatesville, Texas that is currently held for sale and is not used as
an operations base. The following table sets forth the Company's principal
manufacturing plants and offices:

BACKLOG
 
     The Company's backlog is based upon customer orders received that the
Company believes are firm. Backlog is comprised of both products to be delivered
and services to be performed. The level of backlog at any particular time is not
necessarily indicative of the future operating performance of the Company as

may be changed at any time and the Company is affected by seasonality. See "Risk
Factors -- Seasonality." At August 31, 1997 and August 31, 1996, the Containment
Products Group's backlog was approximately $11.9 million and $10.5 million,
respectively. For any given date, the Company anticipates that 80% of the
Containment Products Group's backlog will be shipped or performed within 90 days
and 90% will be shipped or performed within 180 days. At August 31, 1997, the
Engineered Products Group's backlog (including pending acquisitions) was
approximately $11.2 million. For any given date, the Company anticipates that
60% of the backlog of the Engineered Products Group will be shipped or performed
within 90 days and 80% will be shipped or performed within 180 days.
 
MATERIALS AND SUPPLIERS
 
   
     Owens Corning and the Company are parties to a supply contract pursuant to
which the Company purchases from Owens Corning the fiberglass used in the
Company's composite products. Under this supply contract, Owens Corning is
required to supply and the Company is required to purchase at least 80% of the
Company's Containment Products group fiberglass requirements through December
31, 1997. The Company has entered into a supply contract with Owens Corning
beginning January 1, 1998, to supply at least 90% of the Company's fiberglass
requirements through December 31, 2000. In addition, this contract contains
certain stabilizing pricing parameters. In addition to Owens Corning, the
Company continues to negotiate with other vendors to ensure a continued supply
of fiberglass to the Company for its production needs.
    
 
   
     The Company is a significant purchaser of resin. Resin is available in
adequate supply from many sources. The Company does not depend upon any single
supplier or source. The Company has identified additional resin suppliers during
the last year, which will allow for competitive bidding should a future pricing
or supply imbalance occur. The Company's ability to operate and to grow is
partially dependent upon its ability to obtain an adequate supply of resin and
fiberglass. The Company believes current market conditions, the above actions
and contractual arrangements make significant raw material cost deviations
unlikely during the next 36 months.
    
 
     For the Company's steel fabrication businesses, the principal materials
used are standard steel shapes, steel plate, fittings, welding gases and paint
and are all currently available in adequate supply from many sources. The
Company does not depend upon any single supplier or source.
 
PATENTS AND TRADEMARKS
 
     The Company owns numerous United States patents and has a number of
trademarks registered in the United States. Although the Company regards its
patents and trademarks to be of value, it believes that in most instances its
manufacturing and technical knowledge and experience are more important to its
competitive position than are its patents and trademarks. The Company does not
consider its business to be dependent on any one or more of such patents or
trademarks.
 
INSURANCE
 
     The Company maintains a comprehensive insurance program providing various
types of coverage for its operations including, without limitation, commercial
general liability, commercial automobile liability, workers' compensation and
employment practices liability, directors and officers liability, business
interruption and property and casualty insurance. All policies are subject to
deductibles and other coverage limitations and are at limits and amounts of
insurance that the Company believes are consistent with customary practices and
standards of companies engaged in similar businesses. Although the Company's
management believes that the Company's insurance is adequate, there can be no
assurance that the Company will be able to maintain adequate insurance at rates
which management considers commercially reasonable, nor can there be any
assurance such coverage will be adequate to cover all claims that may arise.
 
GOVERNMENT REGULATION
 
     The Company is subject to numerous foreign, federal, state and local laws
and regulations relating to the protection of health, safety and the
environment, including the Comprehensive Environmental Response, Compensation
and Liability Act ("CERCLA"), the Clean Water Act, the Clean Air Act (including
the 1990
 
                                       29

Amendments), the Resource Conservation and Recovery Act ("RCRA"), and the
Occupational Safety and Health Act ("OSHA"). Each of these statutes provides for
the imposition of substantial civil and criminal penalties, as well as the
possibility of permit revocation and corrective action orders, for violations of
its requirements. These laws may also provide for retroactive, strict liability,
rendering a party liable for environmental damage without regard to its
negligence or fault. The Company believes that it is in substantial compliance
with such laws. Nevertheless, risks of substantial costs and liabilities are
inherent in certain of its operations, and in certain products produced by the
Company, as they are with other enterprises engaged in similar businesses. Since
its formation, however, the Company's cost of complying with environmental and
health and safety laws and regulations has not been material, but the fact that
such laws or regulations are changed frequently makes predicting the cost or
impact of such laws and regulations on its future operations uncertain.
Modification of existing laws or regulations or the adoption of new laws or
regulations affecting the Company's operations could adversely affect the
Company.
 
  Wastewater
 
     Certain of the Company's facilities discharge process wastewater and storm
water and are subject to the requirements of the federal Clean Water Act and
comparable state statutes. Many of such requirements are embodied in permits
issued to the plants by state and federal environmental agencies. The Company
believes its facilities are generally in compliance with such requirements.
However, both federal and state authorities continue to develop legislation and
regulations to control the discharge of water pollutants. Passage of more
restrictive legislation or regulations could necessitate additional capital
expenditures to reduce discharges of such substances into the environment due to
routine or episodic events.
 
  Air Emissions
 
     Certain of the Company's facilities are subject to the requirements of the
federal Clean Air Act and comparable state statutes. Many of such requirements
are embodied in permits issued to these facilities by governmental agencies. The
Company believes that its operations are in substantial compliance with such
statutes and permits in all states. Amendments to the federal Clean Air Act were
adopted in 1990 (the "1990 Amendments") and contain provisions that may result
in the imposition of certain pollution control requirements with respect to air
emissions from the Company's operations. These amendments direct the EPA to
establish technology-based standards for hazardous air pollutants based on the
use of "maximum achievable control technology" or MACT. By November 15, 1997,
the EPA is scheduled to promulgate MACT standards for the reinforced plastic
composites industry category. These standards may result in tighter emissions
control requirements affecting the Company's fiberglass tank manufacturing
operations. The Company is working with other industry members to assist the EPA
in the development of MACT standards that will be acceptable to the industry.
The 1990 Amendments may also require the Company to obtain new operating permits
for various of its facilities. The Company is currently in the process of
procuring such permits. The adoption of MACT standards applicable to the
Company's operations may result in increased operating or capital expenditures.
At this time, however, the Company does not believe that it will be materially
adversely affected by any emissions control or permit requirements resulting
from the 1990 Amendments.
 
  Superfund
 
     CERCLA, also known as "Superfund," and comparable state laws impose
liability, without regard to fault or the legality of the original act, on
certain classes of persons that contributed to the release of a "hazardous
substance" into the environment. These persons include the owner or operator of
a site and companies that disposed or arranged for the disposal of the hazardous
substances found at a site. Those statutes also authorize governmental
environmental authorities such as the EPA and, in some instances, third parties
to take action in response to threats to the public health and the environment
and to seek to recover from the responsible classes of persons the costs
incurred in cleaning up the hazardous substances that have been released into
the environment and for damages to natural resources. It is also not uncommon
for neighboring landowners and other third parties to file claims for personal
injury and property damage allegedly
 
                                       30
<PAGE>   32
 
caused by the hazardous substances released into the environment. In the course
of its ordinary operations, the Company generates waste, some of which may fall
within the statutory definition of a "hazardous substance" and some of which may
have been disposed of at sites that may require clean up under Superfund. The
Company has been named as a potentially responsible party ("PRP") under CERCLA
or similar state Superfund laws at four sites: the Seaboard Chemical Company
site in Jamestown, North Carolina; the Diaz Refinery site in Diaz, Arizona; the
Bay Drum site in Tampa, Florida; and the Western Processing site in Kent,
Washington. In all such cases, however, the Company has entered into consent
orders resolving its liabilities as a de minimis or de micromis party and the
Company believes that any future liabilities related to these four sites will
not have a material adverse affect on the financial condition of the Company.
The Company's Bellingham, Washington plant is located adjacent to a wood
treatment facility that has been proposed for listing on the EPA's National
Priorities List of Superfund sites (the Oeser Company site). In addition,
contamination has been discovered in Little Squalicum Creek, which is in
proximity to the site. Both sites are listed on the Washington State Priorities
List as awaiting remedial action. It is unknown by the Company what the
magnitude of potential cleanup costs may be for such sites. To date, the Company
has not been named a PRP relative to either site. The Company believes that any
liability relating to its historical disposal practices will not have a material
adverse affect on the financial condition of the Company.
 
  Solid and Hazardous Wastes
 
     The Company generates hazardous and non-hazardous solid wastes which are
subject to the requirements of RCRA and comparable state statutes. The Company
believes that it is in general compliance with such requirements. The RCRA
regulations generally impose requirements on the handling of currently generated
hazardous waste, such regulations may also require "corrective action" with
respect to contamination at facilities caused by the past handling of various
substances. For example, spills and releases of materials from facility
operations might require clean up pursuant to such orders or other remedial
statutes. Though no assurances can be given in this regard, the Company does not
believe that any such clean up activities will have a material adverse affect on
its financial condition.
 
  Safety Regulation
 
     The Company is also subject to the requirements of OSHA and comparable
state statutes. The Company believes that it has operated in substantial
compliance with OSHA requirements, including general industry standards, record
keeping and hazard communicational requirements. The nature of the Company's
business may result from time to time in industrial accidents. On September 10,
1996, an employee died in an accident involving a Hoover tank at the Mira Loma,
California facility. In connection with the accident, criminal charges have been
filed against two of the Company's employees. The Company has engaged counsel to
represent the employees and to vigorously defend them against the charges. The
Company has not been charged. Though no assurances can be given regarding this
accident, the Company does not believe that liabilities associated with this
accident will have a material adverse effect on its financial condition. It is
possible that changes in safety and health regulations or a finding of
non-compliance of current regulations could result in additional capital
expenditures or operating expenses.
 
  Present and Future Environmental Capital Expenditures.
 
     Although it is the Company's policy to comply with all applicable
environmental, health and safety laws and regulations, in many instances the
implementing regulations have not been finalized. Even where regulations or
standards have been adopted, they are subject to varying and conflicting
interpretations and implementation. In many cases, compliance with environmental
regulations or standards can only be achieved by capital expenditures, some of
which may be significant. The Company has no current plans for substantial
capital expenditures with respect to compliance with environmental, health and
safety laws. To the extent estimates are available, capital expenditures for
environmental control facilities are expected to be less than $200,000 for each
of fiscal 1998 and 1999.

EMPLOYEES
 
   
     At November 1, 1997, the Company employed 743 persons. Four collective
bargaining agreements cover 245 employees in California, Pennsylvania, Texas and
Washington. All of these agreements expire between December 1997 and October
1998. The Company considers its employee relations to be good.
    
 
   
LEGAL MATTERS
    
 
     From time to time the Company is a party to what it believes is routine
litigation and proceedings that may be considered as part of the ordinary course
of its business. Except as described above, the Company is not aware of any
current or pending litigation or proceedings that could have a material adverse
effect on the Company's operations, financial condition or cash flow.

STOCK OPTION PLANS
 
  1996 Incentive Stock Option Plan
 
     The Company's 1996 Incentive Stock Option Plan (the "1996 Plan") was
adopted by the Board of Directors and the stockholders of the Company in
February 1996 and subsequently amended effective September 1997. The purpose of
the 1996 Plan is to promote the long-term growth and profitability of the
Company. The 1996 Plan is intended to grant incentive stock option awards to all
employees of the Company; provided, however, that such awards shall be
non-qualified options if they do not meet the requirements for being considered
as incentive stock options. No further options may be granted pursuant to the
1996 Plan.
 
     The 1996 Plan is administered by the Company's Board of Directors. The
Board selects the employees who will receive awards, determines the terms of the
awards to be granted and interprets and administers the 1996 Plan. The Board of
Directors of the Company may terminate or amend the 1996 Plan without
stockholder approval, except to the extent that stockholder approval is required
by the Internal Revenue Code or other applicable law.
 
   
     Awards granted under the 1996 Plan are subject to such terms and conditions
as the Board of Directors may establish. If a recipient of an award under the
1996 Plan ceases to be an employee of the Company by reason of death or
disability, all options theretofore granted to such recipient which are
exercisable at the date of such death or disability may be exercised by such
recipient's estate or the recipient at any time within three months after the
date of such death or disability. Except as provided below, if a recipient of an
award ceases to be an employee of the Company by reason of termination with or
without cause, resignation, retirement, or any reason other than death or
disability, all options awarded to such participant shall automatically
terminate, effective as of such cessation of employment, to the extent not
theretofore exercised. Notwithstanding the foregoing, with respect to options
under the 1996 Plan granted to Mr. Andrews, Mr. Carter and Ms. Smith, if Stephen
T. Harcrow does not hold the office at the Company of President, Chief Executive
Officer or a similar office with responsibility and authority comparable to that
of President or Chief Executive Officer, a recipient of an award who ceases to
be an employee of the Company by reason other than death or disability may
exercise all options theretofore granted and not previously exercised within
three months after the date upon which such recipient's employment is
terminated. Pursuant to the 1996 Plan, the payment of an optionee's exercise
price shall be made in cash. In connection with the merger of CSI with and into
the Company in September 1997, the Company issued options to acquire 254,643
shares of its Common Stock under the 1996 Plan in exchange for options to
acquire 1,400 shares of the common stock of CSI. As part of this transaction,
Mr. Bennett will receive options to acquire 72,750 shares of the Common Stock in
exchange for his CSI stock options (which were originally received in April
1996).
    
 
  1997 Incentive Stock Option Plan
 
     The Company's 1997 Incentive Stock Option Plan (the "1997 Plan") was
adopted by the Board of Directors and the stockholders of the Company in
September 1997. The purpose of the 1997 Plan is to promote the long-term growth
and profitability of the Company. The 1997 Plan is intended to grant incentive
stock option awards to all employees of the Company; provided, however, that
such awards shall be non-qualified options if they do not meet the requirements
for being considered as incentive stock options. Awards of options to acquire up
to an aggregate of 362,873 shares may be granted pursuant to the 1997 Plan.
 
     The 1997 Plan is administered by the Company's Board of Directors. The
Board selects the employees who will receive awards, determines the type and
terms of the awards to be granted and interprets and administers the 1997 Plan.
The Board of Directors of the Company may terminate or amend the 1997 Plan
without stockholder approval, except to the extent that stockholder approval is
required by the Internal Revenue Code or other applicable law.
 
                                       35
<PAGE>   37
 
     Awards granted under the 1997 Plan are subject to such terms and conditions
as the Board of Directors may establish. If a recipient of an award under the
1997 Plan ceases to be an employee of the Company by reason of termination
without cause, resignation, retirement, death or disability, all options
theretofore granted to such recipient which are exercisable at the date of such
event may be exercised by such recipient or such recipient's estate if
applicable, at any time within three months after the date of such event. If a
recipient of an award ceases to be an employee of the Company by reason of
termination with cause, all options awarded to such participant shall
automatically terminate, effective as of such cessation of employment, to the
extent not theretofore exercised.
 
     In September 1997, the Company awarded options effective as of the date of

SALARY CONTINUATION AGREEMENT
 
     Mr. Harcrow is a party to a Salary Continuation Agreement entered into with
the Company in September 1997 which provides for certain payments to his wife in
the event of his death or disability. Upon the occurrence of such event, the
Company shall (i) pay to his wife in monthly installments an annual sum equal to
his annual salary for a period of three years thereafter and (ii) provide and
pay for health insurance for Mr. Harcrow's wife and family for such three year
period. The Salary Continuation Agreement will terminate in the event that Mr.
Harcrow terminates his employment with the Company for any reason other than
death or disability. In addition, the Company's obligations under the agreement
will terminate (i) upon the death of Mr. Harcrow's wife or (ii) upon Mr.
Harcrow's death or disability, if his wife is not then living. The Salary
Continuation Agreement will expire on August 31, 1999. On termination of the
agreement, the benefits described above shall remain in force and effect
thereafter; however, the three-year period for benefits will provide for
benefits only from the date of disability or death of Mr. Harcrow until
September 1, 2002.
 
CONFIDENTIALITY AND NON-COMPETITION AGREEMENTS
 
     Each of Mr. Andrews, Mr. Carter and Ms. Smith has entered into a
Confidentiality and Non-Competition Agreement with the Company. Each agreement
contains a covenant-not-to-compete with the Company during such employee's
period of employment with the Company and for a period of one year following
termination of employment.
 
LIMITATION OF DIRECTORS' LIABILITY AND INDEMNIFICATION
 
     The Company's Certificate of Incorporation provides that to the fullest
extent permitted by Delaware law, the Company's directors will not be liable for
monetary damages for breach of a director's duty of care to the Company and its
stockholders. This provision does not eliminate a director's duty of care, and
in appropriate circumstances, equitable remedies such as an injunction or other
forms of non-monetary relief will remain available under Delaware law. Each
director continues to remain liable for a breach of the director's duty of
loyalty to the Company, for acts or omissions not in good faith or involving
intentional misconduct or a knowing violation of the law, for improper
distributions to stockholders and for any transaction from which the director
derives an improper personal benefit. This provision also does not affect a
director's liability under other laws, such as the federal securities laws.
 
     The Company's Bylaws provide that the Company will indemnify its directors
and officers to the fullest extent permitted by the Delaware General Corporation
Law. Prior to consummation of this Offering, the Company will enter into
indemnification agreements with each of its directors that provide for
indemnification
 
                                       36
<PAGE>   38
 
and expense advancement to the fullest extent permitted under the Delaware
General Corporation Law. Such indemnification agreements include related
provisions intended to facilitate the indemnitee's receipt of such benefits,
including certain provisions applicable to constituent corporations in the event
of certain mergers or acquisitions.
 
COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
     J. Taft Symonds, a member of the Company's Board of Directors, is chairman
of the board of Tetra Technologies, Inc. ("Tetra"). Stephen T. Harcrow, Chairman
and Chief Executive Officer of the Company, serves on the Board of Directors and
Compensation Committee of Tetra. Since the Company does not presently have a
compensation committee, the entire Board of Directors of the Company is
responsible for review of executive compensation.
 
                              CERTAIN TRANSACTIONS
 
TETRA TECHNOLOGIES, INC.
 
   
     During the fiscal year ended June 28, 1997, the Company purchased

Chairman of the Board of Tetra, and Stephen T. Harcrow, the Company's Chairman
and Chief Executive Officer, is also on the Board of Directors of Tetra. All of

are expected to be awarded in November 1997, with construction to begin in
Spring 1998, and if such projects were awarded to the Company, it would receive
payments from Tetra totaling approximately $320,000.
    
 
REDEMPTION OF SERIES A PREFERRED STOCK

                             DESCRIPTION OF CAPITAL STOCK
 
     The Company's authorized capital stock consists of 30,000,000 shares of
Common Stock, par value $.01 per share, 1,000,000 shares of Preferred Stock, par
value $.01 per share (the "Preferred Stock") and 4,800 shares of Series A
Preferred Stock, par value $.01 per share. The discussions of the Common Stock
and Preferred Stock here and elsewhere in this Prospectus are qualified in their
entirety by reference to: (i) the Certificate of Incorporation of the Company,
as amended, a copy of which has been filed as an exhibit to the Registration
Statement of which this Prospectus is a part and (ii) the applicable Delaware
law.
 
     The Company has issued and has outstanding 4,800 shares of its Series A
Preferred Stock, par value $.01 per share. All of such shares are issued to the
founders of the Company, including the Company's current directors who
collectively own approximately 75% of the issued and outstanding shares of
Series A Preferred Stock. The Company intends to use a portion of the proceeds
from this Offering to redeem all of the issued and outstanding shares of the
Series A Preferred Stock for a total aggregate purchase price of approximately
$1,410,000 (including $210,000 for accrued and unpaid dividends through
September 30, 1997).
 
COMMON STOCK
 
     Holders of Common Stock are entitled to one vote per share in the election
of directors and on all other matters on which stockholders are entitled or
permitted to vote. Holders of Common Stock are not entitled to cumulative voting
rights. The Board of Directors is classified into three classes of directors,
with each class of directors consisting of a number of directors as equal in
number as possible, with the term of each class of directors expiring on a
staggered basis. See "Management -- Board of Directors." The classification of
the
 
                                       39
<PAGE>   41
 
Board of Directors may make it more difficult to change the composition of the
Board of Directors and thereby may discourage or make more difficult an attempt
by a person or group to obtain control of the Company.
 
     Subject to the terms of any outstanding series of Preferred Stock, the
holders of Common Stock are entitled to dividends in such amounts and at such
times as may be declared by the Company's board of directors out of funds
legally available therefor. The Common Stock is not subject to any calls or
assessments. Upon liquidation or dissolution, holders of Common Stock are
entitled to share ratably in all net assets available for distribution to
stockholders after payment of any liquidation preferences to holders of
Preferred Stock. Holders of Common Stock have no redemption, conversion or
preemptive rights.
 
PREFERRED STOCK
 
     Shares of Preferred Stock may be issued without stockholder approval. The
board of directors is authorized to issue up to 1,000,000 shares of Preferred
Stock in one or more series and to determine, with respect to any series of
Preferred Stock, the terms and rights of such series, including, without
limitation (i) the number of shares and the name of the series, (ii) the rate
and times at which dividends will be payable on the shares of the series, and
the status of such dividends as cumulative or non-cumulative and as
participating or non-participating, (iii) the prices, times and terms, if any,
at or upon which shares of the series will be subject to redemption, (iv) the
rights, if any, to convert such shares into, or to exchange such shares for,
shares of any other class of stock of the Company, (v) the terms of the sinking
fund or redemption or purchase account, if any, to be provided for shares of the
series, (vi) the rights and preferences, if any, of shares of the series upon
any liquidation, dissolution or winding up of the affairs of, or upon any
distribution of the assets of, the Company, (vii) the limitations, if any,
applicable while the series is outstanding, on the payment of dividends or
making of distributions on, or the acquisition of, the Common Stock or any other
class of stock which does not rank senior to the shares of the series. The
Company has no current plans for issuance of any shares of Preferred Stock. Any
issuance of shares of Preferred Stock may adversely affect the voting powers or
rights of the holders of Common Stock.
 
ANTI-TAKEOVER PROVISIONS OF DELAWARE LAW
 
   
     The Company is subject to Section 203 of the Delaware General Corporation
Law regulating corporate takeovers. Section 203 prevents certain Delaware
corporations, including those whose securities are listed on the Nasdaq National
Market, from engaging in any "business combination" with any "interested
stockholder" for a period of three years following the date that the stockholder
became an interested stockholder, with three exceptions: (i) prior to such date,
the board of directors of the corporation approved either the business
combination or the transaction which resulted in the stockholder becoming an
interested stockholder; (ii) upon the consummation of the transaction which
resulted in the stockholder becoming an interested stockholder, the interested
stockholder owned at least 85% of the voting stock of the corporation
outstanding at the time that the transaction commenced, excluding for purposes
of determining the number of shares outstanding the shares owned by persons who
are both directors and officers of the corporation and the shares owned by
employee stock plans in which employee participants do not have the right to
determine confidentially whether shares held subject to the plan will be
tendered in a tender or exchange offer; or (iii) on or subsequent to the date
that the stockholder became an interested stockholder, the business combination
is approved by the board of directors of the corporation and authorized at an
annual or special meeting of stockholders, and not pursuant to written consent,
by the affirmative vote of at least 66 2/3% of the outstanding voting stock of
the corporation, excluding voting stock owned by the interested stockholder. The
restrictions in Section 203 also do not apply to certain business combinations
proposed by an interested stockholder following the announcement or notification
of one of certain extraordinary transactions involving the corporation (for
example, a proposed tender or exchange offer for 50% or more of the
corporation's outstanding voting stock) which is approved or not opposed by a
majority of the corporation's directors then in office and which is with or by a
person who had not been an interested stockholder during the preceding three
years or who became an interested stockholder with the approval of the
corporation's board of directors.
    
 
     Section 203 defines a "business combination" as, in general: (i) any merger
or consolidation involving the corporation and the interested stockholder; (ii)
any sale lease, transfer, pledge or other disposition to the
 
                                       40
<PAGE>   42
 
interested stockholder of 10% or more of the corporation's assets; (iii) subject
to certain exceptions, any transaction which results in the issuance or transfer
by the corporation to the interested stockholder of any stock of the
corporation; (iv) any transaction involving the corporation which has the effect
of increasing the proportionate share of the stock of any class or series, or of
securities convertible into the stock of any class or series, which is
beneficially owned by the interested stockholder; or (v) the receipt by the
interested stockholder of the benefit of any loans, advances, guarantees,
pledges or other financial benefits provided by or through the corporation.
Section 203 defines an "interested stockholder" as, in general, any person or
entity who or which directly or indirectly beneficially owns 15% or more of the
outstanding voting stock of the corporation and any person or entity affiliated
or associated with or controlling or controlled by that person or entity.
 
     The provisions of Section 203 could operate to delay or prevent the removal
of incumbent directors of the Company or a change in control of the Company.
They also could discourage, impede or prevent a merger, tender offer or proxy
contest involving the Company, even if such an event would be favorable to the
interests of the Company's stockholders generally. By adopting an amendment to
the Company's certificate of incorporation or by-laws, the Company's
stockholders may elect not to have Section 203 apply to the Company effective 12
months after the adoption of the amendment. Neither the Company's Certificate of
Incorporation nor its By-Laws currently exclude the Company from the
restrictions imposed by Section 203.

                        SHARES ELIGIBLE FOR FUTURE SALE
 
   
     Prior to this Offering, there has been no public market for the Common
Stock of the Company. Future sales of substantial amounts of Common Stock in the
public market could adversely affect the market price of Common Stock. Aside
from the 2,100,000 shares sold in this Offering, only a limited number of shares
will be available for sale immediately following completion of this Offering
because of certain contractual and legal restrictions on resale (as described
below). Accordingly, sales of substantial amounts of Common Stock of the Company
in the public market after these restrictions lapse could adversely affect the
prevailing market price and the ability of the Company to raise equity capital
in the future.
    
 
   
     Upon the completion of this Offering, the Company will have outstanding an
aggregate of 4,284,910 shares of Common Stock, assuming no exercise of the
Underwriters' over-allotment option and no exercise of outstanding stock options
and warrants. Of these outstanding shares of Common Stock, the 2,100,000 shares
sold in this Offering will be freely tradeable without restriction or further
registration under the Securities Act, unless purchased by an "affiliate" of the
Company as that term is defined in Rule 144 under the Securities Act.
    
 
     The remaining 2,184,910 shares of Common Stock held by existing
stockholders (the "Restricted Shares") will be "restricted securities" as that
term is defined in Rule 144 under the Securities Act. The Restricted Shares may
be sold in the public market only if they are registered under the Securities
Act or if they qualify for an exemption from registration under Rule 144 under
the Securities Act (which is summarized below). Sales of the Restricted Shares
in the public market, or the availability of the Restricted Shares for sale,
could adversely affect the market price of the Common Stock.
 
     Certain stockholders of the Company, including all executive officers and
directors and the individuals and entities named in the table under "Principal
Stockholders," who will beneficially own in the aggregate 2,184,910 Restricted
Shares after the Offering, have entered into "lock-up" agreements with the
Underwriters, represented by Morgan Keegan & Company, Inc. and Rauscher Pierce
Refsnes, Inc. (the "Representatives"), pursuant to which they have agreed not to
offer, sell, contract to sell, grant any option to purchase or otherwise dispose
of, directly or indirectly, any of their Restricted Shares, or any shares of
Common Stock that they may acquire through the exercise of stock options, for a
period of 180 days from the date of this Prospectus without the prior written
consent of the Representatives. As a result of these contractual restrictions,
shares of Common Stock subject to the lock-up agreements are restricted from
sale until the lock-up agreements expire, notwithstanding that they otherwise
may be eligible for sale under Rule 144. Upon the expiration of the lock-up
agreements, shares will be eligible for sale pursuant to Rule 144.
 
     In general, under Rule 144 as currently in effect, beginning 90 days after
the date of this Prospectus, a person (or persons whose shares are required to
be aggregated) who has beneficially owned Restricted Shares for at least one
year (including the holding period of any prior beneficial owner except an
affiliate of the Company) would be entitled to sell during any three-month
period a number of Restricted Shares that does not exceed the greater of (i) 1%
of the number of shares of Common Stock then outstanding or (ii) the average
weekly trading volume of the Common Stock during the four calendar weeks
preceding the filing of the required notice of sale on Form 144. Sales of
Restricted Shares under Rule 144 are also subject to compliance with certain
conditions relating to the manner of sale, the requirement to file notice of the
sale with the Securities and Exchange Commission on Form 144 and the
availability of current public information about the Company. Under Rule 144(k),
a person who is not deemed to have been an affiliate of the Company at any time
during the 90 days preceding a sale, and who has beneficially owned the
Restricted Shares proposed to be sold for at least two years (including the
holding period of any prior owner except an affiliate), may sell the Restricted
Shares under Rule 144 without regard to any volume limitation or other
conditions or requirements of the rule. Accordingly, unless otherwise
restricted, holders of Restricted Shares who are eligible to use Rule 144(k) may
sell their shares immediately upon completion of this Offering.
 
   
     As of October 31, 1997, there were outstanding options under the 1996 Stock
Plan to purchase 367,833 shares of Common Stock, all of which are presently
exercisable. Of such options, options for 185,940 shares were held by officers
and directors of the Company subject to the lock-up agreements described above.
With respect to the 1997 Plan, effective as of the date of this Prospectus,

Common Stock have been awarded to certain executive officers of the Company. Of
these options, 56,845 will be immediately exercisable upon completion of the
Offering. Shortly after completion of this Offering, the Company intends to file

Stock issued or issuable under the 1996 Plan and the 362,873 shares of Common
Stock issued or issuable under the 1997 Plan. Holders of all of the options
granted under the 1997 Plan prior to this Offering will be subject to lock-up
agreements with the Underwriters with respect to the shares of Common Stock
obtainable thereunder. These registration statements will become effective
automatically upon filing. Accordingly, shares registered under these
registration statements will be available for sale in the public market, subject
to the volume limitations under Rule 144 in the case of sales by affiliates of
the Company, except to the extent that the shares are subject to contractual
restrictions on sale under the lock-up agreements described above.

     The Underwriting Agreement provides that the Underwriters are obligated to
purchase all of the shares of Common Stock offered hereby (other than those
covered by the over-allotment option described below) if any such shares are
purchased. The Company has been advised that the Underwriters propose to offer
the Common Stock to the public at the initial public offering price set forth on
the cover page of this Prospectus and to certain dealers at such price less a
concession not in excess of $          per share of Common Stock. The
Underwriters may allow, and such dealers may reallow, a discount not in excess
of $          per share to other dealers. The initial public offering price and
the concessions and discount to dealers may be changed by the Underwriters after
the public offering.
 
   
     The Company has granted to the Underwriters an option, exercisable for 30
days from the date of this Prospectus, to purchase on a pro rata basis up to
315,000 additional shares of Common Stock from the Company at the initial public
offering price, less underwriting discounts, as shown on the cover page of this
Prospectus. The Underwriters may exercise such option solely for the purpose of
covering over-allotments incurred in the sale of the shares of Common Stock
offered hereby.
    
 
     The Company has agreed to indemnify the Underwriters or to contribute to
losses arising out of certain liabilities, including liabilities under the
Securities Act.
 
   
     The Company, the Company's executive officers and directors, and certain of
the Company's shareholders (in the aggregate, representing 53.6% of the shares
outstanding after the Offering assuming the Underwriters' over-allotment option
is not exercised) have agreed that, for a period of 180 days from the date of
this Prospectus, they will not, directly or indirectly, offer, sell, offer to
sell, contract to sell, grant any option to purchase, or otherwise dispose (or
announce any offer, sale, grant of any option to purchase, or other
    
 
                                       43

disposition) of any additional shares of Common Stock, or any securities
convertible into, or exercisable or exchangeable for, shares of Common Stock,
without the prior written consent of the Underwriters.
 
     The Representatives have informed the Company that the Underwriters do not
intend to confirm sales to any accounts over which they exercise discretionary
authority.
 
     Prior to this Offering, there has been no public market for the shares of
Common Stock. Consequently, the initial public offering price will be determined
through negotiations among the Company and the Representatives. Among the
factors considered in making such determination will be the prevailing market
conditions, the Company's financial and operating history and conditions, the
Company's prospects and the prospects for its industry in general, the
management of the Company, and the market prices of securities for companies in
business related to that of the Company.
 
   
     The Company has applied to list the Common Stock on the Nasdaq National
Market under the symbol "DNLI." The Company has been advised by the
Representatives that each of the Representatives presently intends to make a
market in the Common Stock offered hereby; the Representatives are not obligated
to do so, however, and any market making activity may be discontinued at any
time. There can be no assurance that an active public market for the Common
Stock will develop and continue after the Offering.
    
 
     In connection with this Offering, the Underwriters may engage in
transactions that stabilize, maintain or otherwise affect the market price of
the Common Stock. Such transactions may include stabilization transactions
pursuant to which the Representatives may bid for or purchase Common Stock for
the purpose of stabilizing its market price. The Underwriters also may create a
short position for the account of the Underwriters by selling more Common Stock
in connection with the Offering that they are committed to purchase from the
Company, and in such case the Representatives may purchase Common Stock in the
open market following completion of the Offering to cover all or a portion of
such short position. The Underwriters may also cover all or a portion of such
short position by exercising the Underwriters' over-allotment option referred to
above. In addition, the Representatives, on behalf of the Underwriters, may
impose "penalty bids" under contractual arrangements with the Underwriters
whereby they may reclaim from an Underwriter (or dealer participating in the
Offering) for the account of other Underwriters, the selling concession with
respect to Common Stock that is distributed in the Offering but subsequently
purchased for the account of the Underwriters in the open market. Any of the
transactions described in this paragraph may result in the maintenance of the
price of the Common Stock at a level above that which might otherwise prevail in
the open market. The imposition of a penalty bid might also affect the price of
the Common Stock to the extent that it could discourage resales of the security.
Neither the Company nor any of the Underwriters makes any representation or
prediction as to the direction or magnitude of any effect that the transactions
described above may have on the price of the Common Stock. In addition, neither
the Company nor any of the Underwriters makes any representation that the
Underwriters will engage in such transactions or that such transactions, once
commenced, will not be discontinued without notice.
 
   
     At the request of the Company, the Underwriters have reserved up to 109,250
shares of Common Stock for sale at the initial public offering price to
directors, officers, employees, business associates and related persons of the
Company. The number of shares of Common Stock available for sale to the general
public will be reduced to the extent such persons purchase such reserved shares.
Any reserved shares which are not purchased will be offered by the Underwriters
to the general public on the same basis as the other shares offered hereby.
    
 
                                 LEGAL MATTERS
 
     The legality of the Common Stock offered hereby will be passed upon for the
Company by Hutcheson & Grundy, L.L.P., Houston, Texas. Certain legal matters
will be passed upon for the Underwriters by Vinson & Elkins L.L.P., Houston,
Texas.

                     NOTES TO UNAUDITED PRO FORMA CONDENSED
                       CONSOLIDATED FINANCIAL STATEMENTS
 
(1) BASIS OF PRESENTATION
 
   
     The accompanying unaudited pro forma condensed consolidated financial
statements (the "Pro Forma Financial Statements") are based on adjustments to
the historical consolidated financial statements of Denali Incorporated (the
"Company") to give effect to the acquisitions described in Note 3 (the
"Acquisitions"). The pro forma condensed consolidated balance sheet assumes the
Acquisitions were closed on June 28, 1997. The pro forma condensed consolidated
statement of operations assumes all Acquisitions described in Note 3 were
consummated as of the beginning of the period presented. The pro forma condensed
consolidated statements of operations are not necessarily indicative of results
that would have occurred had the Acquisitions been consummated as of the
beginning of the period presented or that might be attained in the future.
Certain information normally included in financial statements prepared in
accordance with generally accepted accounting principles has been condensed or
omitted pursuant to the rules and regulations of the Securities and Exchange
Commission. The Pro Forma Financial Statements should be read in conjunction
with the historical consolidated financial statements of the Company, the
historical financial statements of the entities acquired in the Acquisitions and
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" included elsewhere in this Prospectus.
    
 
(2) EARNINGS PER SHARE
 
   
     Pro forma earnings per share were computed by dividing net income (or loss)
applicable to common stock by the weighted average number of shares of common
stock, common stock equivalents outstanding during the period and the dilutive
effect of common stock equivalents issued within one year prior to the Offering.
The number of shares of common stock and common stock equivalents has been
retroactively adjusted for the 1715-for-1 stock split. Common stock equivalents
consisted of the number of shares issuable on exercise of the outstanding stock
options less the number of shares that could have been purchased with the
proceeds from the exercise of the options based on the average price of the
common stock during the period. The dilutive effect of common stock issued
within one year prior to the Offering for the periods prior to issuance was
determined in the same manner except that the Offering price of $14 per share
was used for the repurchase price.
    
 
(3) ACQUISITIONS
 
     The acquisitions by the Company have been accounted for as purchases and,
accordingly, the results of operations of the acquired companies have been
included in the consolidated results of operations of the Company from the date
of acquisition.
 
     In December 1994, the Company acquired certain assets and assumed certain
liabilities of the fiberglass composite underground storage tank business of
Owens Corning, including five manufacturing facilities. The purchase price
totaled $16.6 million, consisting of $5.6 million in cash, $9.3 million in notes
payable and approximately $1.7 million in acquisition costs.
 
     On October 27, 1995, the Company acquired certain assets and assumed
certain liabilities of Hoover Containment Systems, Inc., a manufacturer of steel
rectangular ASTs. The purchase price totaled $5.5 million consisting of $5.4
million in cash and acquisition costs of approximately $100,000.
 
     On February 28, 1997, the Company acquired Ershigs, Inc. ("Ershigs"), a
manufacturer of engineered fiberglass reinforced plastic ("FRP"). The $6.1
million purchase price consisted of $5.0 million cash, $1.0 million in a note
payable and acquisition costs of approximately $80,000.
 
   
     In October 1997, the Company acquired SEFCO, Inc. ("SEFCO") for
approximately $4.9 million in net cash and acquisition costs of approximately
$100,000. SEFCO is a manufacturer of engineered field-erected aboveground steel
tanks.

     accounting step-up of the acquisition of LaValley and the purchase of fixed

                         REPORT OF INDEPENDENT AUDITORS
 
Board of Directors
Denali Incorporated
 
     We have audited the accompanying consolidated balance sheets of Denali
Incorporated and subsidiaries (the "Company") as of June 29, 1996, and June 28,
1997, and the related consolidated statements of operations, stockholders'
equity (deficit), and cash flows for the period from December 19, 1994 (date of
inception) to July 1, 1995 and the years ended June 29, 1996 and June 28, 1997.
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 consolidated financial position of
Denali Incorporated, and subsidiaries at June 29, 1996 and June 28, 1997, and
the consolidated results of its operations and its cash flows for the period
from December 19, 1994 (date of inception) to July 1, 1995, and the years ended
June 29, 1996 and June 28, 1997 in conformity with generally accepted accounting
principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                 JUNE 28, 1997
 
1. THE COMPANY
 
ORGANIZATION AND BASIS OF PRESENTATION
 
     Denali Incorporated ("Denali" or the "Company"), a Delaware corporation,
was incorporated on December 19, 1994, and through its wholly owned subsidiaries
is primarily engaged in the manufacture and sale of fiberglass composite
underground storage tanks, steel rectangular aboveground storage tanks, and
engineered fiberglass reinforced plastic products for corrosion resistant
applications.
 
     The Company uses a 52 or 53 week year ending on the Saturday closest to
June 30.
 
     Certain prior year amounts have been reclassified to conform to current
year presentation.
 
2. SIGNIFICANT ACCOUNTING POLICIES
 
CONSOLIDATION
 
     The Consolidated Financial Statements include the accounts of Denali and
its wholly owned subsidiaries. All significant intercompany accounts and
transactions have been eliminated.
 
USE OF ESTIMATES
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires the use of estimates by management.
Actual results could differ from those estimates.
 
INVESTMENTS IN EQUITY SECURITIES
 
     The Company determines the appropriate classification of investments in
equity securities at the time of purchase and confirms such designation as of
the balance sheet date. Marketable equity securities are classified as
available-for-sale securities and are stated at fair value, with any unrealized
gains and losses, net of tax, reported as a separate component of stockholder's
equity. Realized gains and losses are recognized based on the
specific-identification method for equity securities sold. The Company's
investments are in a mutual fund that holds U.S. Treasury bills. As of June 29,
1996, the fair value of investments in equity securities, using quoted market
prices, approximates their carrying value.
 
CASH AND CASH EQUIVALENTS
 
     The Company considers all cash accounts and money market accounts to be
cash and cash equivalents.
 
FAIR VALUE OF FINANCIAL INSTRUMENTS
 
     The carrying amounts of cash, prepaid expenses, accounts receivable, and
other current assets and accounts payable approximate fair values due to the
short-term maturities of these instruments. The carrying value of the Company's
revolving lines of credit and notes payable approximates fair value because the
rates on such lines are variable, based on current market.
 
STOCK-BASED COMPENSATION
 
     The Company accounts for stock-based compensation arrangements under the
provisions of Accounting Principles Board Opinion No. 25, Accounting for Stock
Issued to Employees.
 
INVENTORIES
 
     Inventories are determined using actual cost or a standard cost method
based on a first-in, first-out ("FIFO") basis. FIFO inventory is stated at the
lower of cost or market.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
PROPERTY, PLANT, AND EQUIPMENT
 
     Property, plant, and equipment are stated at cost. Depreciation is computed
by the straight-line method using rates based on the estimated useful lives of
the related assets. Estimated useful lives used for depreciation purposes are as
follows:

Buildings and improvements..................................  20 years
Machinery and equipment.....................................  3 to 10 years
</TABLE>
 
ACCOUNTING FOR LONG-LIVED ASSETS
 
     In March 1995, the FASB issued Statement No. 121, Accounting for the
Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of,
which requires impairment losses to be recorded on long-lived assets used in
operations when indicators of impairment are present and the undiscounted cash
flows estimated to be generated by those assets are less than the assets'
carrying amount. Statement No. 121 also addresses the accounting for long-lived
assets that are expected to be disposed of. The Company adopted Statement No.
121 in the first quarter of fiscal 1997 and the effect of adoption was not
material.
 
GOODWILL
 
     Goodwill represents the excess cost of companies acquired over the fair
value of their tangible assets. Goodwill is being amortized on a straight-line
basis over 40 years. The carrying value of goodwill is reviewed if the facts and
circumstances suggest that it may be impaired. If this review indicates that
goodwill will not be recoverable, as determined based on the undiscounted cash
flows of the entity acquired over the remaining amortization period, the
Company's carrying value of the goodwill will be reduced by the estimated
shortfall of the undiscounted cash flows. Accumulated amortization was $27,000
and $69,000 for the years ended June 29, 1996 and June 28, 1997, respectively.
Amortization expense was $-0-, $27,000, and $42,000 for the period December 19,
1994 (date of inception) to July 1, 1995, and for the years ended June 29, 1996,
and June 28, 1997.
 
REVENUES FROM LICENSE ARRANGEMENTS
 
   
     The Company has certain license agreements whereby it receives royalties
equal to the greater of a certain percentage of the licensee's sales for
products based on the Company's proprietary technology and processes or a
guaranteed amount as specified in the agreements. The agreements expire between
1998 and 2011. The Company recognizes the actual royalties due or the guaranteed
amount under these license agreements in the period of the licensee's sales.
    
 
REVENUE RECOGNITION
 
     Revenues from sales of products fabricated at plant locations are
recognized using the units-of-delivery method of accounting. Revenues from
certain long-term construction contracts, usually performed on job sites, are
recognized on the percentage-of-completion method. Earned revenue is based on
the percentage that incurred costs to date are to total estimated costs after
giving effect to the most recent estimates of total cost. The cumulative impact
of revisions in total cost estimates during the progress of work is reflected in
the year in which these changes become known. Earned revenue reflects the
original contract price adjusted for agreed-upon claim and change order revenue,
if any.
 
     Losses expected to be incurred on jobs in process, after consideration of
estimated minimum recoveries from claims and change orders, are charged to
income as soon as such losses are known. Selling and administrative expenses are
charged to income in the year incurred and are not allocated to contracts in
progress.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
ADVERTISING
 
     The Company expenses all advertising costs as incurred. Advertising costs
incurred were $193,000, $330,000, and $402,000 for the period December 19, 1994
(date of inception) to July 1, 1995 and for the years ended June 29, 1996 and
June 28, 1997, respectively.
 
INCOME TAXES
 
     The Company uses the liability method of accounting for income taxes. Under
the liability method, deferred income taxes are determined based on differences
between financial reporting and tax basis of assets and liabilities and are
measured using the enacted tax rates that will be in effect when the differences
reverse.
 
RESEARCH AND DEVELOPMENT COSTS
 
     The costs of materials and equipment that are acquired for research and
development activities, and which have alternative future uses, are capitalized
and depreciated over the period of future benefit. All other research and
development costs are charged against earnings in the period incurred. Research
and development costs expensed were $242,000, $492,000, and $319,000 for the
period December 19, 1994 (date of inception) to July 1, 1995, and for the years
ended June 29, 1996 and June 28, 1997, respectively.
 
CONCENTRATION OF CREDIT RISK
 
     Financial instruments that could potentially subject the Company to
concentrations of credit risk are accounts receivable. The Company continuously
evaluates the creditworthiness of its customers and generally does not require
collateral. The Company's customer base consists of major commercial
organizations and independent sub-contractors. No customer accounted for 10% or
more of revenues for the period December 19, 1994 (date of inception) to July 1,
1995, and for the years ended June 29, 1996 and June 28, 1997.
 
PER SHARE INFORMATION
 
     Per share amounts have been computed by dividing net income (or loss)
applicable to common stock (net income or loss, less preferred stock dividends)
by the weighted average number of common shares and common stock equivalents
outstanding during the respective periods. Common stock equivalent shares
consist of the incremental shares issuable upon the exercise of stock options
(using the treasury stock method where applicable). Shares for which stock
options were granted within a 12-month period prior to an initial public
offering are treated as outstanding for all periods presented. Therefore, shares
for which options were granted subsequent to September 1996 have been considered
as having been outstanding for purposes of the calculation (using the treasury
stock method with the offering price used for fair market value) for all periods
presented. Common stock equivalent shares from stock options granted prior to
September 1996 are excluded from computations if their effect is antidilutive.
 
     In February 1997, the Financial Accounting Standards Board issued Statement
No. 128, Earnings Per Share, which is required to be adopted by the Company in
the second quarter of fiscal 1998. At that time, the Company will be required to
change the method currently used to compute earnings per share and to restate
all prior periods. Under the new requirements for calculating primary earnings
per share, the dilutive effect of common stock equivalents will be excluded. The
impact of Statement No. 128 on primary and fully diluted net income (loss) per
share is not expected to be material for the period December 19, 1994 (date of
inception) to July 1, 1995, and for the years ended June 29, 1996 and June 28,
1997.
 
CAPTIVE INSURANCE PROGRAM
 
     In January 1996, the Company entered into a captive insurance program for
its workers' compensation, auto, and general liability coverages. The program
provides for certain reinsurance on claims over $250,000
 
                                      F-15

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
and certain other claims. The Company uses actuarial determined information
provided by the captive insurance company to determine its estimated liability.
 
ACCOUNTING CHANGES
 
     In 1997, the FASB issued Statement No. 130, Reporting Comprehensive Income,
and Statement No. 131, Disclosures about Segments of an Enterprise and Related
Information. These statements, which are effective for periods beginning after
December 15, 1997, expand and modify disclosures and, accordingly, will have no
impact on the Company's reported financial position, results of operations, or
cash flows.
 
3. ACQUISITIONS
 
     Effective December 31, 1994, the Company purchased certain assets and
assumed certain liabilities of the Owens-Corning Fiberglass(R) underground tank
group (the "tank group"). The acquisition was accounted for under the purchase
method of accounting, whereby the assets and liabilities of the tank group
acquired through the Company's subsidiaries were adjusted to their estimated
fair values at the acquisition date, which exceeded the purchase price by
approximately $4.1 million. Accordingly, the excess amount was allocated to
reduce the basis of property, plant, and equipment (except assets held for sale
as discussed below).
 
     Under the purchase agreement, the Company acquired net assets of $16.6
million, including five manufacturing facilities, two of which were closed by
the Company after acquisition, in exchange for $5.6 million in cash, $1.8
million in notes payable, and $7.5 million in a subordinated unsecured note
payable. The Company incurred approximately $1.7 million in acquisition costs.
The consolidated financial statements reflect all operations for the acquired
company since January 1, 1995.
 
     Effective October 27, 1995, the Company purchased certain assets and
assumed certain liabilities of Hoover Containment Systems, Inc., a manufacturer
of above-ground storage tanks made of steel. The acquisition was accounted for
under the purchase method of accounting whereby the assets and liabilities of
the acquired company were adjusted to their estimated fair values at the
acquisition date.
 
     Under the purchase agreement, the Company acquired net assets of $3.8
million in exchange for $5.4 million in cash and incurred approximately $100,000
in acquisition costs resulting in the recording of goodwill of approximately
$1.7 million. The consolidated financial statements reflect all operations for
the acquired company since the date of acquisition.
 
     Effective February 28, 1997, the Company acquired all of the issued and
outstanding stock of Ershigs, a manufacturer of fiberglass-reinforced plastic
composites for corrosion-resistant applications. The acquisition was accounted
for under the purchase method of accounting whereby the assets and liabilities
of Ershigs were adjusted to their estimated fair values at the acquisition date,
which exceeded the purchase price by approximately $1.3 million. Accordingly,
the excess amount was allocated to reduce the basis of property, plant, and
equipment (except for assets held for sale as discussed below).
 
     Under the purchase agreement, the Company acquired net assets of $7.4
million in exchange for $5.0 million in cash and $1.0 million in a subordinated
unsecured note payable. The Company incurred approximately $80,000 in
acquisition costs. The consolidated financial statements reflect all operations
for the acquired company since the date of acquisition.

ASSETS HELD FOR SALE
 
     Assets held for sale are recorded on the balance sheet at amounts equal to
estimated net realizable values adjusted for anticipated earnings or losses,
interest and other carrying costs until sale.
 
     The assets held for sale of $3.6 million identified at the date of
acquisition of the tank group consisted primarily of two manufacturing
facilities and related manufacturing equipment. The two manufacturing facilities
were closed in early 1995 and had insignificant operations after the date of
acquisition. One manufacturing facility was sold in December 1995 at its
previously recorded net realizable value. The other manufacturing facility was
sold in June 1996, with the Company recognizing a loss of $208,000 due to a
decline in the market value of the property during 1996. Certain of the
manufacturing equipment was sold during the year ended June 28, 1997 under
licensing arrangements with the Company recognizing a gain on the sale of the
equipment of $312,000. At June 28, 1997, the remaining assets held for sale of
$700,000 consist of certain manufacturing equipment which the Company primarily
expects to sell under similar license arrangements or through an international
joint venture.
 
   
     The assets held for sale of $820,000 identified at the date of acquisition
of Ershigs consisted primarily of a manufacturing facility and related
manufacturing equipment. The manufacturing facility was closed in May 1997 with
operating losses of $68,000 eliminated from the Company's results of operations
for the year ended June 28, 1997. The assets are anticipated to be sold within a
year from the acquisition date.

     FCI's long-term debt agreement provides for a revolving credit note not to
exceed the lesser of $10 million or an amount (the borrowing base) based on
accounts receivable and inventories as specified in the agreement's borrowing
base formula. Borrowings under the revolving credit note totaled $4.6 million
and $4.8 million at June 29, 1996 and June 28, 1997, respectively. The borrowing
base formula yielded a maximum borrowing base of $8.1 million at June 28, 1997.
The debt agreement provides, among other things, for the maintenance of certain
minimums, as defined, for net income, working capital, tangible net worth,
interest coverage, debt coverage, capital expenditures, and average
availability.
 
     HCI's long-term debt agreement provides for a revolving credit note not to
exceed the lesser of $6.5 million less the outstanding term note balance or an

     The unsecured note payable is subordinated to FCI's revolving credit note
and term note. However, payment of interest on the subordinated note is
permitted under FCI's senior debt agreement. The unsecured note payable allowed
FCI to make two in-kind interest payments whereby accrued interest is added to
the outstanding principal balance. FCI made in-kind interest payments of
$375,000 and $394,000 during the

period December 19, 1994 (date of inception) to July 1, 1995, and the year ended
June 29, 1996, respectively. FCI paid interest of $827,000 during the year ended
June 28, 1997.
 
   
     At June 28, 1997, the Company was not in compliance with certain financial
covenants in FCI's, HCI's, and Ershigs' long-term agreements with a financial
institution. The Company has obtained amendments or waivers of these certain
covenants in FCI's, HCI's and Ershigs' loan agreements which cure any non-
compliance with such covenants as of June 28, 1997 and through the first quarter
of fiscal 1998. On October 24, 1997, the Company refinanced all of the related
debt with a new financial institution and the new terms are reflected in the
financial statements.
    
 
   
     On October 24, 1997, the Company's subsidiaries entered into a senior
credit facility, as amended, with a new bank to refinance its revolving and term
credit arrangements at FCI, Hoover, and Ershigs and to finance the acquisitions
of LaValley and SEFCO. Borrowings outstanding under its existing revolving and
term credit arrangements at June 28, 1997 were $10.5 million and $2.8 million,
respectively. The new senior credit facility provides for a maximum of $19.7
million revolving credit notes due in October 2002, and a maximum of $10.5
million in term loans with equal monthly payments of $100,000 plus interest due
in October 2002 or upon the termination of the revolving credit notes. The new
credit notes may be extended for an initial term of five years and may be
renewed in increments of one year thereafter, unless notice of termination is
provided by either party 90 days prior to an anniversary date. The new revolving
credit notes provide for borrowings, at the Company's option, at either the
Bank's prime rate plus  1/2% or LIBOR plus 2 3/4%. Borrowings under the new
revolving credit notes will be based on accounts receivable and inventory as
specified in the agreement's borrowing base formula. The new term loans provide
for borrowings, at the Company's option, at either the Bank's prime rate plus
 1/2% or LIBOR plus 3%. The new senior credit facility provides availability for
letters of credit up to $1.5 million subject to availability of borrowing
capacity under the revolving credit notes. The new senior credit facility
requires the Company's subsidiaries to maintain certain financial covenants and
requires an annual fee of 0.375% on the unused portion of the revolving credit
notes. The new senior credit facility is secured by accounts receivable,
property, equipment and general intangible assets of the Company's subsidiaries.
The Company has classified its existing revolving and term credit arrangements
in the accompanying consolidated balance sheet as of June 28, 1997 based on the
terms of the new senior credit facility.
    
 
   
     In connection with the extinguishment of its existing revolving and term
credit arrangements upon funding of the new senior credit facility in October
1997, the Company paid prepayment penalties of $323,000. In addition, the
Company charged to expense unamortized debt origination costs of $295,000 in
October 1997. These charges will be recognized in the Company's consolidated
financial statements as an extraordinary loss, net of tax, in the quarter ended
December 27, 1997.
    
 
   
     Scheduled maturities of long-term debt at June 28, 1997 based on the terms
of the new senior credit facility are as follows (in thousands):

9. COMMITMENTS AND CONTINGENCIES
 
     The Company utilizes fiberglass, resin and steel as the primary raw
materials in its production processes. Fiberglass is occasionally in short
supply and subject to price fluctuations in response to market demands. The
Company entered into a supply agreement with a major supplier, which requires
that the supplier provide and the Company purchase at least 80% of the Company's
fiberglass requirements from the supplier. The contract expired on December 31,
1999. The Company and supplier are currently negotiating the terms of a
modification to the supply contract which would provide for an extension of at
least one year and certain stabilizing pricing parameters tied to a consumer
price index. In addition, the Company continues to negotiate with other vendors
to ensure a continued supply of fiberglass to meet the Company's production
needs. The Company is also a significant purchaser of resin and steel. The
Company does not depend upon any single supplier or source for steel or resin
requirements.
 
     The Company has not encountered any significant difficulty to date in
obtaining raw materials in sufficient quantities to support its operations at
current or expected near-term future levels. However, any disruption in raw
material supply or abrupt increases in raw material prices could have an adverse
effect on the Company's operations.
 
     The Company and its subsidiaries are, from time to time, subject to various
lawsuits and claims and other actions arising out of the normal course of
business. The Company is also subject to contingencies pursuant to environmental
laws and regulations that in the future may require the Company to take action
to correct the effects on the environment of prior manufacturing and waste
disposal practices. Accrued environmental liabilities at June 28, 1997 were
$575,000 and, in management's opinion, such accruals are appropriate based on
existing facts and circumstances. Under more adverse circumstances, however,
this potential liability could be higher. Current year expenditures were not
material.
 
     While the effect on future results of these items is not subject to
reasonable estimation because considerable uncertainty exists, in the opinion of
management and Company counsel, the ultimate liabilities resulting from such
claims will not materially affect the consolidated financial position, results
of operations or cash flows of the Company.

     The Company has elected to follow Accounting Principles Board Opinion No.
25, Accounting for Stock Issued to Employees (ABP 25), and related
interpretations in accounting for its employee stock options.
 
     Pro forma information regarding net income and earnings per share is
required by FASB Statement No. 123, Accounting for Stock-Based Compensation (FAS
123), which also requires that the information be determined as if the Company
had accounted for its employee stock options granted subsequent to July 1, 1995
under the fair value method of FAS 123. The fair value for these options was
estimated at the date of grant using a minimum value option pricing model. The
minimum value method calculated a fair value that is approximately the same as
recorded by the Company according to APB 25; therefore, pro forma presentation
has not been included.
 
14. GAIN SHARING PLAN
 
     During fiscal year 1995, the Company adopted a gain sharing plan that

18. SUBSEQUENT EVENTS
 
INITIAL PUBLIC OFFERING
 
   
     The Company filed a registration statement with the Securities and Exchange
Commission ("SEC") in September 1997 and an amendment to the registration
statement in November 1997 to register the sale of shares of its common stock.
The Company intends to use the net proceeds of the sale to repay a portion of
the outstanding indebtedness under its credit facilities, to repay $218,000 for
a bank note payable, to repay $6.7 million of a subordinated unsecured note
payable to a supplier, to repay the $1.1 million unsecured note payable
(including interest) to a seller, to redeem the outstanding shares of preferred
stock totaling approximately $1.4 million, including accrued and unpaid
dividends, and to fund general working capital purposes.

     Supplemental net income per share is $0.40 for the year ended June 28, 1997
and is determined by adding back to net income used for the calculation of net
income per share the interest expense, net of taxes associated with the debt
which will be retired by the proceeds of the offering and adding the dividends
paid or accrued associated with the preferred stock which will be redeemed by
the proceeds of the offering. The number of shares outstanding used in
calculating supplemental net income per share was the weighted average common
shares outstanding after giving effect to the estimated number of shares that
would be required to be sold in the offering to repay the debt and redeem the
preferred stock.
 
COMMON STOCK
 
     On September 23, 1997, the Company effected a 1,715-for-1 stock split. All
stockholders' equity balances and disclosures in the accompanying financial
statements have been retroactively restated for the stock split. The effect of
the stock split was to transfer an amount equal to the par value of the new
shares issued from additional paid-in capital to common stock.
 
   
ACQUISITIONS
    
 
   
     In October 1997, the Company acquired all of the issued and outstanding
stock of SEFCO, Inc., a manufacturer of aboveground steel storage tanks for
approximately $4.9 million in cash, which is net of cash acquired of
approximately $600,000, and direct acquisition costs of approximately $100,000.
    
 
   
     In October 1997, the Company acquired all of the issued and outstanding
stock of GL&V/LaValley Construction, Inc., a company engaged in the installation
of underground storage tanks for $3.9 million in cash and direct acquisition
costs of approximately $100,000, with a two-year non-compete agreement.
    
 
1997 STOCK OPTION PLAN
 
     In September 1997, the Company adopted an incentive stock option plan (the
"1997 Plan"). The 1997 Plan permits the granting of both incentive stock options
and non-qualified stock option awards to all employees of the Company. Awards to
acquire up to an aggregate of 362,873 shares may be granted pursuant to the 1997
Plan. The Board of Directors selects the employees who will receive the awards,
determines the type and terms of the awards to be granted and interprets and
administers the 1997 Plan.
 
     In September 1997, the Company awarded options to acquire 171,030 shares of
the Company's common stock. 142,113 of the options vest 40% immediately and the
remainder over a four year period. The remaining 28,917 options vest ratably
over four years. All of the options were granted at fair market value which
equaled the public offering price.
 
REORGANIZATION OF SUBSIDIARIES AND EXCHANGE OF STOCK OPTIONS.
 
     Effective September 1997, the Company completed a reorganization of it
subsidiaries. As part of the reorganization one of the Company's subsidiaries,
Containment Solutions, Inc. ("CSI") was merged into Denali. As a result, the
outstanding options to purchase common stock of CSI were exchanged for options
to purchase common stock of the Company. At June 28, 1997 the CSI stock option
plan has 1,400 options outstanding at an exercise price of $259. In September
1997, the Company exchanged the CSI options to a total of 254,643 options to
purchase the Company's common stock at an exercise price of $1.42. In connection
with the exchange, the Company will recognize a compensation charge in the
quarter ended September 27, 1997 of approximately $2.3 million.
 
     A summary of CSI's stock option activity and related information prior to
the exchange for the years ended June 29, 1996 and June 28, 1997 follows:

              NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS
    
 
   
1. GENERAL
    
 
   
     The consolidated financial statements of Denali Incorporated and its
wholly-owned subsidiaries (the "Company") included herein have been prepared
without audit pursuant to the rules and regulations of the Securities and
Exchange Commission (the "SEC"). Accordingly, certain information and footnote
disclosures normally included in financial statements prepared in accordance
with generally accepted accounting principles have been omitted. The Company
believes that the presentations and disclosures herein are adequate to make the
information not misleading. The consolidated financial statements reflect all
elimination entries and adjustments (consisting of normal recurring adjustments)
necessary for a fair presentation of the interim periods.
    
 
   
     The results of operations for the interim periods are not necessarily
indicative of the results of operations to be expected for the full year. These
consolidated financial statements should be read in conjunction with the
Company's audited consolidated financial statements and notes included elsewhere
in this Prospectus.

     Inventories consist of the following at September 27, 1997 (in thousands):

</TABLE>
    
 
   
3. INCOME TAXES
    
 
   
     The Company follows the liability method of accounting for income taxes.
Under this method, deferred income tax assets and liabilities are determined
based on differences between the financial statement and income tax bases of
assets and liabilities using enacted tax rates in effect for the year in which
the differences are expected to reverse. The Company's interim provisions for
income taxes were computed using its estimated effective tax rate for the year.
The Company's provision for income taxes differs from the U.S. statutory rate of
34% due primarily to the non-recurring compensation charge, discussed in Note 6,
being non-deductible for income tax purposes.
    
 
   
4. PER SHARE INFORMATION
    
 
   
     Per share amounts have been computed by dividing net income (or loss)
applicable to common stock (net income or loss, less preferred stock dividends)
by the weighted average number of common shares and common stock equivalents
outstanding during the respective periods. Common stock equivalent shares
consist of the incremental shares issuable upon the exercise of stock options
(using the treasury stock method where applicable). Shares for which stock
options were granted within a 12-month period prior to an initial public
offering are treated as outstanding for all periods presented. Therefore, shares
for which options were granted subsequent to September 1996 have been considered
as having been outstanding for purposes of the calculation (using the treasury
stock method with the offering price used for fair market value) for all periods
presented. Common stock equivalent shares from stock options granted prior to
September 1996 are excluded from computations if their effect is antidilutive.
    
 
   
     In February 1997, the Financial Accounting Standards Board issued Statement
No. 128, Earnings Per Share, which is required to be adopted by the Company in
the second quarter of fiscal 1998. At that time, the Company will be required to
change the method currently used to compute earnings per share and to restate
all prior periods. Under the new requirements for calculating primary earnings
per share, the dilutive effect of

      NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
    
 
   
common stock equivalents will be excluded. The impact of Statement No. 128 on
primary and fully diluted net income (loss) per share is not expected to be
material for the quarter ended September 27, 1997.
    
 
   
5. 1997 STOCK OPTION PLAN
    
 
   
     In September 1997, the Company adopted an incentive stock option plan (the
"1997 Plan"). The 1997 Plan permits the granting of both incentive stock options
and non-qualified stock option awards to all employees of the Company. Awards to
acquire up to an aggregate of 362,873 shares may be granted pursuant to the 1997
Plan. The Board of Directors selects the employees who will receive the awards,
determines the type and terms of the awards to be granted and interprets and
administers the 1997 Plan.
    
 
   
     In September 1997, the Company awarded options to acquire 171,030 shares of
the Company's common stock. 142,113 of the options vest 40% immediately and the
remainder over a four year period. The remaining 28,917 options vest ratably
over four years. All of the options were granted at fair market value which
equaled the public offering price.
    
 
   
6. REORGANIZATION OF SUBSIDIARIES AND EXCHANGE OF STOCK OPTIONS
    
 
   
     Effective in September 1997, the Company completed a reorganization of it
subsidiaries. As part of the reorganization, one of the Company's subsidiaries,
Containment Solutions, Inc. ("CSI") was merged into Denali. As a result, the
outstanding options to purchase common stock of CSI were exchanged for options
to purchase common stock of the Company. At June 28, 1997 the CSI stock option
plan had 1,400 options outstanding at an exercise price of $259. In September
1997, the Company exchanged the CSI options for a total of 254,643 options to
purchase the Company's common stock at an exercise price of $1.42. In connection
with the exchange, the Company recognized a non-recurring compensation charge in
the quarter ended September 27, 1997 of approximately $2.3 million.
    
 
   
7. INITIAL PUBLIC OFFERING
    
 
   
     The Company filed a registration statement with the Securities and Exchange
Commission ("SEC") in September 1997 and an amendment to the registration
statement in November, 1997 to register the sale of shares of its common stock.
The Company intends to use the net proceeds of the sale to repay a portion of
the outstanding indebtedness under its credit facilities, to repay $218,000 for
a bank note payable, to repay $6.7 million of a subordinated unsecured note
payable to a supplier, to repay the $1.1 million unsecured note payable
(including interest) to a seller, to redeem the outstanding shares of preferred
stock totaling approximately $1.4 million, including accrued and unpaid
dividends, and to fund general working capital purposes.
    
 
   
     Supplemental net loss per share is $(0.40) for the quarter ended September
27, 1997 and is determined by adding back to net loss used for the calculation
of net loss per share the interest expense, net of taxes, associated with the
debt which will be retired by the proceeds of the offering and adding the
dividends paid or accrued associated with the preferred stock which will be
redeemed by the proceeds of the offering. The number of shares outstanding used
in calculating supplemental net loss per share was the weighted average common
shares outstanding after giving effect to the estimated number of shares that
would be required to be sold in the offering to repay the debt and redeem the
preferred stock.
    
 
   
COMMON STOCK
    
 
   
     On September 23, 1997, the Company effected a 1,715-for-1 stock split. All
stockholders' equity balances and disclosures in the accompanying financial
statements have been retroactively restated for the stock split. The effect of
the stock split was to transfer an amount equal to the par value of the new
shares issued from additional paid-in capital to common stock.

8. SUBSEQUENT EVENTS
    
 
   
     In October 1997, the Company acquired all of the issued and outstanding
stock of SEFCO, Inc., a manufacturer of engineered field-erected steel tanks and
accessories for use in the municipal, agrochemical and petroleum industries, for
$4.9 million in cash, which is net of cash acquired of approximately $600,000,
and direct acquisition costs of $100,000.
    
 
   
     In October 1997, the Company acquired all of the issued and outstanding
stock of GL&V/LaValley Construction, Inc., a manufacturer and installer of
fiberglass reinforced plastic products for $3.9 million in cash and direct
acquisition costs of $100,000, with a two-year non-compete agreement.
    
 
   
9. UNAUDITED PRO FORMA BALANCE SHEET
    
 
   
     In connection with the initial public offering of the Company's Common
Stock, the Company will pay the dividends in arrears on the Company's preferred
stock and redeem the preferred shares for cash from the proceeds of the initial
public offering. The pro forma unaudited balance sheet gives effect to the
redemption of the preferred shares for cash.

                         REPORT OF INDEPENDENT AUDITORS
 
Denali Incorporated
 
     We have audited the accompanying balance sheet of Hoover Containment
Systems, Inc. (the "Company"), a wholly owned subsidiary of Hoover Group, Inc.
as of December 31, 1994 and the related statements of operations, stockholder's
equity, and cash flows for the year ended December 31, 1994, and the period from
January 1, 1995 to October 27, 1995. 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 Hoover Containment Systems,
Inc. at December 31, 1994, and the results of its operations and its cash flows
for the year then ended and the period from January 1, 1995 to October 27, 1995,
in conformity with generally accepted accounting principles.

                        HOOVER CONTAINMENT SYSTEMS, INC
 
                         NOTES TO FINANCIAL STATEMENTS
                                OCTOBER 27, 1995
 
1. THE COMPANY
 
ORGANIZATION AND BASIS OF PRESENTATION
 
     The Hoover Containment Systems, Inc. (the "Company") is a manufacturer of
above-ground steel tanks in the domestic U.S. market. The Company was
incorporated on January 7, 1994 as a wholly owned subsidiary of Hoover Group,
Inc. through a contribution to the Company of $300,000. Prior to its
incorporation, the Company was a division of Hoover Group, Inc. On October 27,
1995 the net assets of the Company were acquired by Denali, Inc. for $5.4
million in cash.
 
   
     These financial statements have been prepared on a basis that management
believes to be reasonable and appropriate and include the historical balance
sheets, results of operations and cash flows of the Company, including allocated
portions of the Hoover Group's general and administrative expenses directly
related to the Company's operations. The amounts allocated by the Hoover Group
are not necessarily indicative of the actual costs which may have been incurred
had the Company operated as an entity unaffiliated with the Hoover Group.
However, the Company believes that the allocations are reasonable and in
accordance with the Securities and Exchange Commission's Staff Accounting
Bulletin No. 55.
    
 
2. SIGNIFICANT ACCOUNTING POLICIES
 
INVENTORIES
 
     Inventories are determined using actual cost based on a first-in, first-out
("FIFO") basis. FIFO inventory is stated a the lower of cost or market.
 
PROPERTY, PLANT, AND EQUIPMENT
 
     Property, plant, and equipment are stated at cost. Depreciation is computed
by the straight-line method using rates based on the estimated useful lives of
the related assets. Estimated useful lives used for depreciation purposes are as
follows:
 
<TABLE>

Buildings and improvements...........................         20 years
Machinery and equipment..............................    3 to 10 years
</TABLE>
 
GOODWILL
 
     Goodwill represents the excess cost of companies acquired over the fair
value of their tangible assets. Goodwill is being amortized on a straight-line
basis over 40 years. The carrying value of goodwill is reviewed if the facts and
circumstances suggest that it may be impaired. If this review indicates that
goodwill will not be recoverable, as determined based on the undiscounted cash
flows of the entity acquired over the remaining amortization period, the
Company's carrying value of the goodwill will be reduced by the estimated
shortfall of the undiscounted cashflows. Goodwill amortization expense was
$8,600 and $7,100 for the year ended December 31, 1994 and the period from
January 1, 1995 through October 27, 1995, respectively. Accumulated amortization
was $30,000 at December 31, 1994.
 
PATENTS
 
     Patents, including costs to acquire the patents of $129,000, are being
amortized on a straight basis over fifteen years. The Company periodically
evaluates the recoverability of patents by assessing whether the unamortized
balance can be recovered over its remaining life through cash flows generated by
the underlying assets. Patent amortization expense was $7,500 and $53,900 for
the year ended December 31, 1994 and the period from January 1, 1995 through
October 27, 1995, respectively. Accumulated amortization was $7,500 at December
31, 1994.

                        HOOVER CONTAINMENT SYSTEMS, INC
 
                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
OTHER ASSETS
 
     Included in other assets are non-compete agreements that total $472,500.
The agreements were recorded at costs when the agreements were signed and are
being amortized over the life of the agreement. Amortization expense was $60,000
and $50,000 for the year ended December 31, 1994 and the period from January 1,
1995 through October 27, 1995, respectively. Accumulated amortization was
$397,500 at December 31, 1994.
 
INCOME TAXES
 
     The Company's taxable income is included in the consolidated federal income
tax return of the Parent. The federal tax provision is substantially the same
provision as if the Company was required to file its own federal income tax
return on a separate company basis.
 
     The Company uses the liability method of accounting for income taxes. Under
the liability method, deferred income taxes are determined based on differences
between financial reporting and tax bases of assets and liabilities and are
measured using the enacted tax rates that will be in effect when the differences
reverse.
 
RESEARCH AND DEVELOPMENT COSTS
 
     The costs of materials and equipment that are acquired for research and
development activities, and which have alternative future uses, are capitalized
and depreciated over the period of future benefit. All other research and
development costs are charged against earnings in the period incurred. Research
and development costs expensed were $38,000 and $35,000 for the year ended
December 31, 1994 and during the period from January 1, 1995 to October 27,
1995, respectively.
 
ADVERTISING COSTS
 
     All advertising costs are expensed when incurred. Costs which are included
in selling, general and administrative expense were $99,000 and $23,000 for the
year ended December 31, 1994 and during the period from January 1, 1995 to
October 27, 1995, respectively.
 
REVENUE RECOGNITION
 
     Revenues from sales of products fabricated at plant locations are
recognized using the units-of-delivery method of accounting.
 
FAIR VALUE OF FINANCIAL INSTRUMENTS
 
     The carrying amounts of accounts receivable, accounts payable and
short-term debts approximate fair values due to the short-term maturities of
these instruments. The carrying value of the Company's long-term debt
approximates fair value because the rate on such debt is not significantly
different from the current market rate.
 
USE OF ESTIMATES
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

CONCENTRATION OF CREDIT RISK
 
     The Company's trade customers are geographically dispersed throughout the
United States and are concentrated in the petrochemical industry. The Company
had one customer individually exceeding 5% of accounts receivable, accounting
for approximately 6% of total accounts receivable at December 31, 1994.
 
3. PURCHASE OF ASSETS
 
     In 1994, the Company purchased certain patents, inventory, and fixed assets
from a manufacturer of above-ground steel storage tanks for approximately
$860,000 including a note payable for $200,000 and acquisition costs of
$130,000. The assets were recorded at their fair values at the acquisition date.

Denali Incorporated
 
     We have audited the accompanying balance sheet of Ershigs, Inc., (the
"Company"), as of December 31, 1996, and the related statements of operations,
stockholder's equity, and cash flows for the period from January 1, 1997 to
February 27, 1997, for each of the two years in the period ended December 31,
1996, and for the period from October 1, 1994 to December 31, 1994. These
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
     We conducted our audits in accordance with 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 Ershigs, Inc. at December
31, 1996, and the results of its operations and its cash flows for the period
from January 1, 1997 to February 27, 1997, for each of the two years in the

                         NOTES TO FINANCIAL STATEMENTS
 
1. DESCRIPTION OF THE BUSINESS AND BASIS OF ACCOUNTING
 
     Ershigs, Inc. (the Company) is a contract designer and manufacturer of
fiberglass reinforced plastic composites for corrosion resistant applications in
the domestic U.S. market. The Company operates fabrication plants located in
Washington, North Carolina and Texas.
 
     The Company was acquired by CBI Industries, Inc. (CBI) on May 21, 1993 and
became a wholly-owned subsidiary of CBI. As a result of the acquisition of the
Company by CBI, the Company recorded goodwill of $5.1 million.
 
     On January 12, 1996, pursuant to the merger agreement dated December 22,
1995, CBI became a subsidiary of Praxair, Inc. (Praxair). As a result of the
acquisition of CBI by Praxair and Praxair's intent to sell the Company, the
financial statements reflect a new basis of accounting as of January 12, 1996.
The new basis of accounting resulted in the Company's assets and liabilities
being adjusted to their estimated net realizable value based on the ultimate
disposition value in February 1997, adjusted for the operating losses of the
Company. The new basis of accounting adjustments, primarily related to the
adjustment of the Company's assets and liabilities to net realizable values, has
a significant effect on the Company's future results of operations for the
periods subsequent to December 31, 1995. The more significant adjustments relate
to the write-off of unamortized goodwill, a reduction in the basis of fixed
assets and recognition of the related deferred tax asset, which significantly
reduces depreciation and amortization expense. The results of operations from
January 1, 1996 to January 11, 1996 are not considered significant to the
financial statements and are included in the accompanying statement of
operations for the year ended December 31, 1996.
 
   
     These financial statements have been prepared on a basis that management
believes to be reasonable and appropriate and include the historical balance
sheets, results of operations and cash flows of the Company, including allocated
portions of its parent company's general and administrative expenses directly
related to the Company's operations. The amounts allocated by its parent company
are not necessarily indicative of the actual costs which may have been incurred
had the Company operated as an entity unaffiliated with its parent company.
However, the Company believes that the allocations are reasonable and in
accordance with the Securities and Exchange Commission's Staff Accounting
Bulletin No. 55.
    
 
     On February 28, 1997, the Company was acquired by Denali Incorporated
(Denali) in a stock purchase for $6 million. In connection with the acquisition
of the Company by Denali, the fabrication plant in Texas was closed.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  USE OF ESTIMATES
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements. Estimates also affect the reported amounts of revenues and expenses
during the reporting period. Actual results could differ from those estimates.
 
  FAIR VALUE OF FINANCIAL INSTRUMENTS
 
     The carrying amounts of accounts receivable and accounts payable
approximate fair values due to the short-term maturities of these instruments.
The carrying value of the Company's long-term debt approximates fair value
because the rate on such debt is variable, based on current market.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
  INVENTORY
 
     Inventory of raw materials and work-in-process is stated at the lower of
cost (determined by the first-in, first-out method) or market. Work-in-process
includes capitalization of labor and overhead costs.
 
  PROPERTY, PLANT AND EQUIPMENT
 
     Property, plant and equipment are stated at cost. Improvements which
increase the useful life of property and replacements of major components of
property are capitalized, while maintenance, repairs and minor replacements are
expensed as incurred.
 
     Depreciation is provided on a straight-line basis over the estimated useful
lives of the related assets. The estimated useful lives range from 3 to 10 years
for equipment and from 10 to 50 years for buildings and land improvements.
 
  INCOME TAXES
 
     The Company's results are included in the consolidated federal income tax
return filed by its parent company. The Company uses the liability method of
accounting for income taxes. Under the liability method, deferred income taxes
are determined based on differences between the financial reporting and tax
bases of assets and liabilities and are measured using the enacted tax rates
that will be in effect when the differences reverse.
 
     The policy of the parent company is for each U.S. subsidiary to currently
recognize any federal income tax expense, as computed on a separate subsidiary
basis. Any resulting tax liability or receivable is remitted to or received from
the parent through the advances from parent account.
 
  GOODWILL
 
     Prior to the acquisition of the Company's parent by Praxair, goodwill
represented the excess cost of the purchase of the Company by CBI over the fair
value of the Company's tangible assets at the date of acquisition. Goodwill was
being amortized on a straight-line basis over 20 years. The goodwill was
eliminated in the new basis of accounting adjustments as a result of the January
1996 acquisition of the Company by Praxair.
 
  RESEARCH AND DEVELOPMENT COSTS
 
     The costs of materials and equipment that are acquired for research and
development activities, and which have alternative uses, are capitalized and
depreciated over the period of future benefit. All research and development
costs are charged against earnings in the period incurred. Research and
development costs expensed were $-0-, $27,000, $104,000, and $10,000 during the
period from October 1, 1994 to December 31, 1994, the years ended December 31,
1995 and 1996 and the period from January 1, 1997 to February 27, 1997,
respectively.
 
  REVENUE RECOGNITION
 
     Revenues from sales of products fabricated at plant locations are
recognized using the units-of-delivery method of accounting. Revenues from
certain long-term construction contracts, usually performed on job sites, are
recognized on the percentage-of-completion method. Earned revenue is based on
the percentage that incurred costs to date bear to total estimated costs after
giving effect to the most recent estimates of total cost. The cumulative impact
of revisions in total cost estimates during the progress of work is reflected in
the year in which these changes become known. Earned revenue reflects the
original contract price adjusted for agree-upon claim and change order revenue,
if any.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
     Losses expected to be incurred on jobs in process, after consideration of
estimated minimum recoveries from claims and change orders, are charged to
income as soon as such losses are known. Selling and administrative expenses are
charged to income in the year incurred and are not allocated to contracts in
progress.
 
3. LONG-TERM DEBT
 
     The balance of long-term debt at December 31, 1996 consists of a note
payable due in monthly installments of $33,333, plus interest at the bank's
prime rate plus 1% (9.5% at December 31, 1996). This note is collateralized by
virtually all the assets of the Company. The note payable requires the Company
to comply with certain financial covenants, the most restrictive of which
includes the maintenance of liability and leverage ratios as well as limitations
on dividends, additional borrowings and advances to affiliates. The Company was
in compliance with all covenants as of December 31, 1996. The note matures
$400,000 and $300,000 in the year ended December 31, 1997 and 1998,
respectively. In February, 1997, the note payable was repaid in full by the
parent company through the advances from parent account.

5. CONCENTRATION OF CREDIT RISK
 
     The Company's trade customers are geographically dispersed throughout the
United States and are concentrated in the power utilities, pulp and paper and
chemical industries. The Company continuously evaluates the creditworthiness of
its customers and generally does not require collateral. The Company had 8
customers individually exceeding 5% of accounts receivable, accounting for
approximately 68% of total accounts receivable at December 31, 1996.
 
6. COMMITMENTS AND CONTINGENCIES
 
     The Company is subject to various lawsuits and claims and other actions
arising in the normal course of business. The Company is also subject to
contingencies pursuant to environmental laws and regulations that in the future
may require the Company to take action to correct the effects on the environment
of prior manufacturing and waste disposal practices. Accrued environmental
liabilities at December 31, 1996 were $411,000 and, in management's opinion,
such accruals are appropriate based on existing facts and circumstances. Under
more adverse circumstances, however, this potential liability could be higher.
Current expenditures have not been material.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
     While the effect on future results of these items is not subject to
reasonable estimation because considerable uncertainty exists, in the opinion of
management and Company counsel, the ultimate liabilities resulting from such
claims will not materially affect the financial position, results of operations
or cash flows of the Company.
 
     Due to the nature of the contracting business, lawsuits occasionally arise.
It is not possible to predict the results of specific lawsuits; however, the
Company's management believes that there are no issues or incidents that would
be material to its financial position, results of operations or cash flows. In
addition, the Company has given certain guarantees in connection with the
performance of contracts.
 
7. INCOME TAXES
 
     Deferred income taxes reflect the net tax effects of temporary differences
between the carrying amounts of assets and liabilities for financial reporting
purposes and the amounts used for income tax purposes. Significant components of
the Company's deferred tax assets and liabilities are as follows (In thousands):

                         NOTES TO FINANCIAL STATEMENTS
                                AUGUST 16, 1997
 
1. ORGANIZATION AND SUMMARY OF ACCOUNTING POLICIES
 
     GL&V/LaValley Construction, Inc. (the "Company" or "LCI"), a Mississippi
corporation, is wholly owned by GL&V/LaValley Industries, Inc. (the "Parent" or
"LII"), a Washington corporation. LCI markets and installs equipment and parts
primarily for the paper pulp industry throughout North America. On August 23,
1996, LII became a wholly owned subsidiary through a stock purchase of GL&V
Holdings, Inc., a Washington corporation which is wholly owned by Groupe
Laperriere & Verreault Inc., a Canadian corporation. The stock purchase of the
Parent was accounted for under the purchase method and the amount of the
purchase price allocated to the Company was allocated based on the fair value of
the assets acquired and liabilities assumed, which approximated the net book
value of the Company.
 
   
     These financial statements have been prepared on a basis that management
believes to be reasonable and appropriate and include the historical balance
sheets, results of operations and cash flows of the Company, including allocated
portions of the Parent's general and administrative expenses directly related to
the Company's operations. The amounts allocated by the Parent are not
necessarily indicative of the actual costs which may have been incurred had the
Company operated as an entity unaffiliated with the Parent. However, the Company
believes that the allocations are reasonable and in accordance with the
Securities and Exchange Commission's Staff Accounting Bulletin No. 55.
    
 
REVENUE AND COST RECOGNITION
 
     Revenues from contracts with customers for manufacture, repair, or
installation of equipment are recognized on the percentage-of-completion method,
measured by the percentage of construction costs incurred to date to estimated
total costs for each contract. Expended construction costs are considered by
management to be the best available measure of progress on these contracts.
Construction costs include all direct material, equipment, labor, subcontractor,
and indirect costs related to contract performance. General and administrative
costs are charged to expense as incurred. Provisions for estimated losses on
uncompleted contracts are made in the period such losses are determined. Changes
in job performance, job conditions, and estimated profitability, including those
arising from contract penalty provisions and final contract settlements may
result in revisions to costs and income and are recognized in the period the
revisions are determined.
 
     The asset, "Costs and estimated earnings on uncompleted contracts in excess
of related billings," represents revenues recognized in excess of amounts
billed.
 
     Contracts other than those described above are generally accounted for on a
time-and-material basis. Revenues and accounts receivable from such jobs are
recorded at the amount billable based on the costs incurred.
 
INVENTORIES
 
     Inventories consist of raw materials and are valued at the lower of average
cost or market, with cost determined by the moving average method, which
approximates the first-in/first-out method.
 
PROPERTY, PLANT, AND EQUIPMENT
 
     Property, plant, and equipment are stated at cost. Depreciation is charged
to income over the estimated useful lives of the respective assets using the
straight-line method, over lives of 31.5 years for building and improvements and
5 to 7 years for machinery and equipment, furniture and fixtures, and vehicles.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
INCOME TAXES
 
     The Company's taxable income is included in the consolidated federal income
tax return of the Parent. The federal tax provision is substantially the same
provision as if the Company were required to file its own federal income tax
return on a separate company basis.
 
     The Company uses the liability method of accounting for income taxes. Under
the liability method, deferred income taxes are determined based on differences
between financial reporting and tax bases of assets and liabilities, and are
measured using the enacted tax rates that will be in effect when the differences
reverse.
 
USE OF ESTIMATES
 
     In preparing financial statements in conformity with generally accepted
accounting principles, management is required to make estimates and assumptions
that affect the reported amounts of assets and liabilities, the disclosure of
contingent assets and liabilities at the date of the financial statements, and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.
 
FAIR VALUE OF FINANCIAL INSTRUMENTS
 
     The carrying amount of cash, prepaid expenses, accounts receivable,
accounts payable, and accrued expenses approximate fair values due to the
short-term maturities of these instruments. The book values of cash, trade
receivables, and trade payables are considered to be representative of their
respective fair values because of their short-term nature.
 
2. COSTS AND ESTIMATED EARNINGS ON UNCOMPLETED CONTRACTS
 
     Costs and estimated earnings on uncompleted contracts at August 16, 1997

                         NOTES TO FINANCIAL STATEMENTS
 
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
COMPANY'S ACTIVITIES
 
     SEFCO, Inc. (the "Company"), is engaged in the business of the fabrication
and erection of above-ground steel storage tanks for municipalities and the
petroleum and grain industries. Work is performed primarily under fixed-price
contracts.
 
SUBSIDIARY COMPANIES
 
     The Company holds 100% of the stock of two subsidiary companies, Marvel
Painting and Construction, Inc., and SEFCO of Arkansas, Inc. Both subsidiaries
are inactive shells, thus the financial statements reflect only the financial
position, operations and cash flows of SEFCO, Inc.
 
REVENUE AND COST RECOGNITION
 
     Revenues from fixed-price contracts are recognized on the
percentage-of-completion method. No revenue is recognized on a contract until
substantial costs have been incurred. The percentage of completion is measured
by the ratio of costs incurred to date to estimated total costs on the contract.
 
     Contract costs include all direct materials, labor and subcontract costs,
and those indirect costs related to contract performance, such as indirect
labor, supplies, tools, repairs, and equipment costs. Selling, general, and
administrative costs are charged to expense as incurred. Provisions for
estimated losses on uncompleted contracts are made in the period in which such
losses are determined. Changes in job performance, job conditions, and estimated
profitability, including those arising from contract penalty provisions, and
final contract settlements may result in revisions to costs and income and are
recognized in the period in which the revisions are determined.
 
     The asset, "Costs and estimated earnings on incomplete contracts in excess
of billings," represents revenues recognized in excess of amounts billed. The
liability, "Billings in excess of costs and estimated earnings on incomplete
contracts," represents amounts billed in excess of revenues recognized.
 
CASH AND CASH EQUIVALENTS
 
     Cash and cash equivalents consist of all highly liquid investments with a
maturity of three months or less when purchased.
 
USE OF ESTIMATES
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect certain reported amounts and disclosures. Accordingly,
actual results could differ from those estimates.
 
DEPOSITS HELD IN FINANCIAL INSTITUTIONS
 
     The Company had demand deposits on hand in financial institutions which
exceeded depositor's insurance provided by the applicable guaranty agency by
$90,817, $361,287, and $1,339,804 at December 31, 1994, 1995, and 1996,
respectively.
 
PROPERTY, EQUIPMENT, AND DEPRECIATION
 
     Property and equipment are recorded at cost. Depreciation is computed on
the straight-line method based on the estimated useful lives of the related
assets. Construction machinery and furniture are being depreciated

over periods of five to ten years. Autos and trucks have estimated useful lives
of three to five years. Leasehold costs have estimated useful lives of 27 to 39
years.
 
     Maintenance, repairs, and minor renewals are charged to operations as
incurred. Improvements and major renewals are capitalized. Upon sale or
disposition of properties, the asset account is relieved of the cost, and the
accumulated depreciation account is charged with depreciation taken prior to the
sale; any resultant gain or loss is credited or charged to earnings.
 
INCOME TAXES
 
     Deferred income taxes are provided for differences in timing of reporting
income for financial statement and tax purposes arising from differences in the
methods of accounting for construction contracts, depreciation, and warranty
reserves. Construction contracts are reported for tax purposes on the completed
contract method and for financial statement purposes on the
percentage-of-completion method. Accelerated depreciation is used for tax
reporting, and straight-line depreciation is used for financial statement
reporting. The Company has established a reserve fund for warranties which is
not currently deductible for tax purposes.
 
2. ACCOUNTS RECEIVABLE -- CONTRACTS
 
     Accounts receivable are comprised of the following:

     For the years ended December 31, 1994, 1995, and 1996, the federal income
tax provision was less than the amount of taxes computed at the 34% statutory
federal income tax rate because of permanent differences related to expenses
which were not deductible for tax purposes and the federal benefit of state
income taxes.

5. PENSION
 
     During 1994 the Company had a profit sharing plan which covered
substantially all employees of the Company. Employees become eligible for
participation after two years of service.
 
     In 1995, the Company converted its profit sharing plan to a 401(k)
retirement plan (the "Plan") which covers substantially all of the employees of
the Company. The Plan allows employees to defer up to 15% of their compensation,
with the Company matching 100% of the first 6% of the participant's
contribution. Participants are immediately and fully vested in employer
contributions. The Company accrued contributions to the pension plan of $-0-,
$65,425, and $89,723 for the years ended December 31, 1994, 1995, and 1996,
respectively.
 
6. RELATED PARTY TRANSACTIONS
 
     The Company rents land and facilities owned by the stockholders of the
Company and pays insurance, maintenance, and utility bills incurred at the
premises in addition to rent. The Company paid $36,000 in rent payments in 1994,
1995, and 1996.
 
     The stockholders own certain construction equipment which they lease to the
Company on a month-to-month basis. Rental rates are equivalent to rates
available in the marketplace. The Company paid $144,000, $144,000, and $228,000
in the years ended December 31, 1994, 1995, and 1996, respectively, for the use
of this equipment.
 
7. REVOLVING LINE OF CREDIT
 
     In April 1996, the Company entered into a $450,000 revolving line of credit
with interest at 1% above the New York prime rate to provide operating capital.
The line is collateralized by all accounts, contracts, contract rights, and
general intangibles and by all inventory, equipment, and leasehold improvements.
The line expires April 22, 1997. At December 31, 1996, the Company had not
borrowed funds against the line.
 
8. CONTINGENT LIABILITY
 
     The Company has the normal contingencies inherent to construction
activities and a general commitment to correct certain deficiencies in
construction for a period of one year after completion of a construction
contract. Such contingencies and commitments have not been material in prior
years, and in the opinion of management, the Company has adequate insurance
coverage and no material contingencies will result from present or future
claims.
 
9. CONCENTRATION OF CREDIT RISK
 
     The company extends credit to customers as a normal course of business. At
December 31, 1996, the Company had extended credit to two customers totaling
$246,000 or 30% of accounts receivable-contracts.

1. GENERAL
 
     The financial statements of SEFCO, Inc. (the "Company"), included herein
have been prepared without audit pursuant to the rules and regulations of the
Securities and Exchange Commission. Accordingly, certain information and
footnote disclosures normally included in financial statements prepared in
accordance with generally accepted accounting principles have been omitted. The
Company believes that the presentations and disclosures herein are adequate to
make the information not misleading.
 
     The results of operations for the interim periods are not necessarily
indicative of the results of operations to be expected for the full year. These
financial statements should be read in conjunction with the Company's audited
financial statements and notes included elsewhere in the Prospectus.
 
   
2. INCOME TAXES
    
 
   
     The Company follows the liability method of accounting for income taxes.
Under this method, deferred income tax assets and liabilities are determined
based on differences between the financial statement and income tax bases of
assets and liabilities using enacted tax rates in effect for the year in which
the differences are expected to reverse. The Company's interim provisions for
    
   
income taxes were computed using its estimated effective tax rate for the year.

                         REPORT OF INDEPENDENT AUDITORS
                        ON FINANCIAL STATEMENT SCHEDULE
 
   
     We have audited the consolidated financial statements of Denali
Incorporated and subsidiaries (the "Company") as of June 29, 1996, and June 28,
1997, and the related consolidated statements of operations, stockholders'
equity (deficit), and cash flows for the period from December 19, 1994 (date of
inception) to July 1, 1995 and the years ended June 29, 1996 and June 28, 1997,
and have issued our report thereon dated August 27, 1997 (included elsewhere in
this Registration Statement). Our audits also included the financial statement
schedule listed in Item 16(b) of this Registration Statement. This schedule is
the responsibility of the Company's management. Our responsibility is to express
an opinion based on our audits.
    
 
     In our opinion, the financial statement schedule referred to above, when
considered in relation to the basic financial statements taken as a whole,
presents fairly in all material respects the information set forth therein.

</TABLE>
    
 
   
ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS
    
 
     As permitted by Delaware law, the Company's Certificate of Incorporation
limits the personal liability of directors. The Certificate of Incorporation
provides that a director of the Company will not be personally liable to the
Company or its shareholders for monetary damages for breach of fiduciary duty as
a director, except for liability (i) for any breach of the director's duty of
loyalty to the Company or its stockholders, (ii) for acts or omissions not in
good faith or which involve intentional misconduct or a knowing violation of
law, (iii) payment of an improper dividend or improper repurchase of the
Company's stock under Section 174 of the Delaware General Corporation Law, or
(iv) for any transaction from which the director derived any improper personal
benefit. The Company's Certificate of Incorporation further provides that in the
event the Delaware General Corporation Law is amended to allow the further
elimination or limitation of the liability of directors, then the liability of
the Company's directors shall be limited or eliminated to the fullest extent
permitted by the amended Delaware General Corporation Law. This provision is
intended to afford directors additional protection from, and limit their
potential liability for, suits alleging a breach of the duty of care by a
director. The Company believes that this provision will assist it in securing
the services of directors who are not employees of the Company. While
stockholders may be unable to recover monetary damages against directors for
actions that are in violation of their fiduciary duties, it may be possible to
obtain injunctive or other equitable relief with respect to such actions.
 
     Under Article 6 of the Company's Bylaws as currently in effect, each person
who is or was a director or officer of the Company or a subsidiary of the
Company, or who serves or served any other enterprise or organization at the
request of the Company or a subsidiary of the Company, shall be indemnified by
the Company to the full extent permitted by the Delaware General Corporation
Law.
 
     Under such law, to the extent that such person is successful on the merits
in defense of a suit or proceeding brought against him by reason of the fact
that he is or was a director or officer of the Company, or serves or served any
other enterprise or organization at the request of the Company, he shall be
indemnified against expenses (including attorneys' fees) actually and reasonably
incurred in connection with such action.
 
     Under such law, if unsuccessful in defense of a third party civil suit or a
criminal suit, or if such suit is settled, such a person shall be indemnified
against both (i) expenses, including attorneys' fees, and (ii) judgments, fines
and amounts paid in settlement if he acted in good faith and in a manner he
reasonably
 
                                      II-1
<PAGE>   127
 
believed to be in, or not opposed to, the best interests of the Company, and,
with respect to any criminal action, had no reasonable cause to believe his
conduct was unlawful.
 
     If unsuccessful in defense of a suit brought by or in the right of the
Company, where such suit is settled, such a person shall be indemnified under
such law only against expenses (including attorneys' fees) actually and
reasonably incurred in the defense or settlement of such suit if he acted in
good faith and in a manner he reasonably believed to be in, or not opposed to,
the best interests of the Company, except that if such person is adjudged to be
liable in such a suit for negligence or misconduct in the performance of his
duty to the Company, he cannot be made whole even for expenses unless the court
determines that he is fully and reasonably entitled to indemnity for such
expenses.
 
     Prior to consummation of this Offering, the Company will enter into
indemnification agreements with each of its directors that provide for
indemnification and expense advancement to the fullest extent permitted under
the Delaware General Corporation Law. Such indemnification agreements include
related provisions intended to facilitate the indemnitee's receipt of such
benefits, including certain provisions applicable to constituent corporations in
the event of certain mergers or acquisitions.
 
     Delaware corporations also are authorized to obtain insurance to protect
officers and directors from certain liabilities, including liabilities against
which the corporation cannot indemnify its directors and officers. The Company
has purchased and maintains a directors' and officers' liability policy for such
purposes.
 
     Reference is made to the form of Underwriting Agreement filed as Exhibit
1.01 to this Registration Statement for certain provisions regarding the
indemnification of the Company, its officers and directors and any controlling
persons by the Underwriters against certain liabilities for information
furnished by the Underwriters.
 
     Insofar as indemnification for liabilities under the Securities Act may be
permitted to directors, officers or persons controlling the Registrant pursuant
to the foregoing provisions, the Registrant has been informed that in the
opinion of the Commission such indemnification is against public policy as
expressed in the Securities Act and therefore is unenforceable.
 
ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES
 
     In the past three years, the Company has not issued any of its securities
that were not registered under the Securities Act of 1933 (the "Securities Act")
except as follows:
 
          (a) On December 19, 1994, the Company issued 1,500,000 shares of
     Common Stock, $.01 par value (the "Common Stock") to certain individuals
     and entities in connection with the organization and initial capitalization
     of the Company for an aggregate purchase price of $1,500,000.
 
          (b) On April 12, 1995, the Company granted to Stephen T. Harcrow an
     option to purchase 126,910 shares of Common Stock. No consideration was
     paid in this transaction.
 
          (c) On May 31, 1995, the Company issued 126,910 shares of Common Stock
     to Stephen T. Harcrow upon his exercise of his stock option. Consideration
     of $18,500 was paid to the Company in connection with this transaction.
 
          (d) On April 2, 1996, the Company granted to R. Kevin Andrews, Melford
     S. Carter, Jr. and Cathy L. Smith options to purchase in the aggregate
     113,190 shares (37,730 shares each) of Common Stock pursuant to the
     Company's 1996 Incentive Stock Option Plan. No consideration was paid in
     this transaction.
 
   
          (e) On September 18, 1997, the Company granted to certain employees of
     the Company, effective as of effective date of this Registration Statement,
     options to purchase in the aggregate 171,030 shares of Common Stock
     pursuant to the Company's 1997 Incentive Stock Option Plan. No
     consideration was paid in this transaction.
    
 
          (f) On September 25, 1997, the Company issued options to acquire
     254,643 shares of its Common Stock to holders of options to acquire 1,400
     shares of the common stock of Containment Solutions, Inc.
 
                                      II-2
<PAGE>   128
 
     ("CSI"), a wholly-owned subsidiary of the Company, in connection with a
     merger of CSI with and into the Company.
 
     Except for (a) above, the number of shares of Common Stock set forth above
have been adjusted to reflect (i) an 0.0008-for-one split effected in April 1995
and (ii) a 1,715-for-one split effected in September 1997. The transactions
described in paragraphs (a), (c) and (f) above were exempt from the registration
requirement of the Securities Act pursuant to Section 4(2) thereof as
transactions by an issuer not involving a public offering. The transactions
described in paragraphs (b), (d) and (e) above were exempt from the registration
requirement of the Securities Act pursuant to Section 2(3) thereof as
transactions not involving a "sale."

ITEM 17. UNDERTAKINGS
 
     The undersigned Registrant hereby undertakes that:
 
          (1) For purposes of determining any liability under the Securities
     Act, the information omitted from the form of prospectus filed as a part of
     this Registration Statement in reliance upon Rule 430A and contained in the
     form of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or
     (4) or 497(h) under the Securities Act shall be deemed to be part of this
     Registration Statement as of the time it was declared effective.
 
                                      II-4
<PAGE>   130
 
          (2) For the purpose of determining any liability under the Securities
     Act, each post-effective amendment that contains a form of prospectus shall
     be deemed to be a new registration statement relating to the securities
     offered therein, and the offering of such securities at that time shall be
     deemed to be the initial bona fide offering thereof.
 
     The Registrant hereby undertakes to provide to the Underwriters, at the
closing specified in the Underwriting Agreements, certificates in such
denominations and registered in such names as required by the Underwriters to
permit prompt delivery to each purchaser.
 
     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the provisions described in Item 14, above, or otherwise,
the Registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Securities Act and is, therefore unenforceable. In the event that a claim
for indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Securities
Act and will be governed by the final adjudication of such issue.

                 hereinafter called the "Prospectus");

                          (b)              No order preventing or suspending
                 the use of any Preliminary Prospectus has been issued by the
                 Commission, and each Preliminary Prospectus, at the time of
                 filing thereof, conformed in all material respects to the
                 requirements of the Act and the rules and regulations of the
                 Commission thereunder, and did not contain an untrue statement
                 of a material fact or omit to state a material fact required
                 to be stated therein or necessary to make the statements
                 therein, in the light of the circumstances under which they
                 were made, not misleading; provided, however, that the
                 foregoing shall not apply to statements or omissions made in
                 reliance upon information furnished in writing to the Company
                 by the Underwriters expressly for use therein;

                          (c)              The Registration Statement conforms,
                 and the Prospectus and any further amendments or supplements
                 to the Registration Statement or the Prospectus will conform,
                 in all material respects to the requirements of the Act and
                 the rules and regulations of the Commission thereunder; the
                 Registration Statement does not and will not, as of the
                 applicable effective date as to the Registration Statement and
                 any amendment thereto, contain an untrue statement of a
                 material fact or omit to state a material fact required to be
                 stated therein or necessary to make the statements therein not
                 misleading; and the Prospectus, as of the date of such
                 Prospectus, does not contain an untrue statement of a material
                 fact or omit to state a material fact necessary in order to
                 make the statements therein, in the light of the circumstances
                 under which they were made, not misleading;

                          (d)              The historical and pro forma
                 financial statements, together with related schedules and
                 notes, set forth in the Prospectus, comply as to form in all
                 material respects with the requirements of the Act.  The
                 historical consolidated financial statements of the Company
                 and its subsidiaries set forth in the Prospectus present
                 fairly (subject, in the case of unaudited interim financial
                 information, to normal year-end adjustments) the consolidated
                 financial position of the Company and its subsidiaries at the
                 respective dates indicated and the consolidated results of
                 operations and cash flows of the Company and its subsidiaries
                 for the respective periods indicated and in accordance with
                 generally accepted accounting principles consistently applied
                 throughout such periods, unless otherwise reflected in the
                 notes to such financial statements.  The historical
                 consolidated balance sheet of the Company set forth in the
                 Prospectus fairly presents its financial position at _______,
                 1997.  The pro forma financial statements of the Company set
                 forth in the Prospectus have been prepared on a basis
                 consistent with the historical statements of the Company,
                 except for the pro forma adjustments specified therein.  The
                 other financial and statistical information and data included
                 in the Prospectus are, in all material respects, accurately
                 presented and prepared on

                 a basis consistent with such historical and pro forma
                 financial statements and the books and records of the Company;

                          (e)              The historical financial statements,
                 together with related notes, of Hoover Containment Systems,
                 Inc. ("Hoover"), Ershigs, Inc. ("Ershigs"), GL & V/La Valley
                 Construction, Inc.  ("GL & V/La Valley") and SEFCO, Inc.
                 ("SEFCO") (collectively, the "Acquired Companies"), set forth
                 in the Prospectus present fairly (subject, in the case of
                 unaudited interim financial information, to normal year-end
                 adjustments) the financial position of the Acquired Companies
                 at the respective dates indicated and the results of
                 operations and cash flows of the Acquired Companies for the
                 respective periods indicated and in accordance with generally
                 accepted accounting principles consistently applied throughout
                 such periods, unless otherwise reflected in the notes to such
                 financial statements.  The historical balance sheet of Hoover
                 set forth in the Prospectus fairly presents its financial
                 position at December 31, 1994.  The historical balance sheet
                 of Ershigs fairly presents its financial position at December
                 31, 1996.  The historical balance sheet of GL & V/La Valley
                 set forth in the Prospectus fairly presents its financial
                 position at August 16, 1997.  The historical balance sheet of
                 SEFCO set forth in the Prospectus fairly presents its
                 financial position at December 31, 1996;

                          (f)              The Company maintains a system of
                 internal accounting control sufficient to provide reasonable
                 assurance that (i) transactions are executed in accordance
                 with management's general or specific authorization; (ii)
                 transactions are recorded as necessary to permit preparation
                 of financial statements in conformity with generally accepted
                 accounting principles and to maintain accountability for
                 assets; (iii) access to assets is permitted only in accordance
                 with management's general or specific authorization; and (iv)
                 the recorded accountability for assets is compared with
                 existing assets at reasonable intervals and appropriate action
                 is taken with respect to any differences;

                          (g)              Neither the Company nor any of its
                 subsidiaries has sustained since the date of the latest
                 audited financial statements included in the Prospectus any
                 loss or interference with its business material to the Company
                 and its subsidiaries considered as one enterprise from fire,
                 explosion, flood or other calamity, whether or not covered by
                 insurance, or from any labor dispute or court or governmental
                 action, order or decree, otherwise than as set forth or
                 contemplated in the Prospectus; and, since the respective
                 dates as of which information is given in the Registration
                 Statement and the Prospectus, there has not been any change in
                 the capital stock or long-term debt of the Company or any of
                 its subsidiaries or any material adverse change, or any
                 development involving a prospective material adverse change,
                 in or affecting the general affairs, management, financial
                 position, stockholders' equity or results of operations of the
                 Company and its subsidiaries considered as one enterprise,
                 otherwise than as set forth or contemplated in the Prospectus;

                          (h)              The Company has been duly
                 incorporated and is validly existing as a corporation in good
                 standing under the laws of the State of Delaware, with

                 transaction of business and is in good standing under the laws
                 of each other jurisdiction in which it owns or leases
                 properties or conducts any business except where the failure
                 so to qualify or to be in good standing would not have a
                 material adverse effect on the business affairs, business
                 prospects, assets, financial position or results of operations
                 of the Company and its subsidiaries considered as one
                 enterprise (a "Material Adverse Effect"); and each direct or
                 indirect subsidiary of the Company has been duly incorporated
                 and is validly existing as a corporation in good standing
                 under the laws of its jurisdiction of incorporation or has
                 been formed and is validly existing as a limited partnership,
                 as the case may be;

                          (i)              The Company has authorized capital
                 stock as set forth in the Prospectus, and all of the issued
                 shares of capital stock of the Company have been duly and
                 validly authorized and issued, are fully paid and
                 non-assessable and conform in all material respects to the
                 description of capital stock contained in the Prospectus; and
                 all of the issued shares of capital stock of, or partnership
                 or other equity ownership interest in, each subsidiary of the
                 Company have been duly and validly authorized and issued, are
                 fully paid and non-assessable and are owned directly or
                 indirectly by the Company, free and clear of all liens,
                 encumbrances, equities or claims except as disclosed in the
                 Prospectus;

                          (j)              The Shares to be issued and sold by
                 the Company to the Underwriters hereunder have been duly and
                 validly authorized and, when issued and delivered against

                          (k)              The issue and sale of the Shares to
                 be sold by the Company and the compliance by the Company with
                 all of the provisions of this Agreement and the consummation
                 of the transactions herein contemplated will not conflict with
                 or result in a breach or violation of any of the terms or
                 provisions of, or constitute a default under, any indenture,
                 mortgage, deed of trust, loan agreement or other agreement or
                 instrument to which the Company or any of its subsidiaries is
                 a party or by which the Company or any of its subsidiaries is
                 bound or to which any of the property or assets of the Company
                 or any of its subsidiaries is subject, nor will such action

                 of Incorporation or By-laws of the Company or any applicable
                 statute or any order, rule or regulation of any court or

                 or qualification of or with any such court or governmental
                 agency or body is required for the issue and sale of the

                 mortgage, deed of trust, loan agreement, lease or other
                 agreement or instrument to which it is a party or by which it
                 or any of its properties may be bound except to the extent it
                 would not result in a Material Adverse Effect;

                          (m)              The statements set forth in the
                 Prospectus under the caption "Description of Capital Stock,"
                 insofar as they purport to constitute a summary of the terms
                 of the capital stock of the Company are accurate and complete
                 in all material respects;

                          (n)              Except as described in the

                 described in the Prospectus;

                          (o)              Other than as set forth in the

                 pending to which the Company or any of its subsidiaries is a
                 party or to the best of the Company's knowledge of which any
                 property of the Company or any of its subsidiaries is the
                 subject which, if determined adversely to the Company or any
                 of its subsidiaries, would individually or in the aggregate
                 have a Material Adverse Effect; and, to the best of the
                 Company's knowledge, no such proceedings are threatened or
                 contemplated by governmental authorities or threatened by
                 others;

                 effect to the offering and sale of the Shares, will not be, an

and each of the Underwriters agrees, severally and not jointly, to purchase
from the Company, at a purchase price per share of $____, the number of Primary
Shares (to be adjusted by you so as to eliminate fractional shares) determined
by multiplying the aggregate number of Shares to be sold by the Company by a
fraction, the numerator of which is the aggregate number of Primary Shares to

         The Company hereby grants to the Underwriters the one-time right to

                 under the securities laws of such jurisdictions as you may
                 request and to comply with such laws so as to permit the

                 as a result of which the Prospectus as then amended or

                                  after due inquiry there are no persons with
                                  registration or similar rights to have any

                                  other financial data in the Registration
                                  Statement or the Prospectus); and nothing has
                                  come to such counsel's attention that would
                                  lead such counsel to believe that either the
                                  Registration Statement or any amendment or
                                  supplement thereto, at the time such

                                  supplement became effective, or the
                                  Prospectus or any amendment or supplement

                                  statement of a material fact or omitted or
                                  omits to state a material fact required to be
                                  stated therein or necessary to make the
                                  statements therein, in light of the
                                  circumstances under which they were made, not
                                  misleading;

                          (d)              On the date of the Prospectus at a
                 time prior to the execution of this Agreement, at 8:30 a.m.,
                 Central Standard Time, on the effective date of any
                 post-effective amendment to the Registration Statement filed
                 subsequent to the date of this Agreement and also at each Time
                 of Delivery, Ernst & Young LLP shall have furnished to you a
                 letter or letters, dated the respective dates of delivery
                 thereof, in form and substance satisfactory to you, to the
                 effect set forth in Annex I hereto;

                          (e)              (i)     Neither the Company nor any
                 of its subsidiaries shall have sustained since the date of the
                 latest audited financial statements included in the Prospectus
                 any loss or interference with its business from fire,
                 explosion, flood or other calamity, whether or not covered by
                 insurance, or from any labor dispute or court or governmental
                 action, order or decree, otherwise than as set forth or
                 contemplated in the Prospectus, and (ii) since the respective
                 dates as of which information is given in the Prospectus there
                 shall not have been any change in the capital stock or
                 long-term debt of the Company or any of its subsidiaries or
                 any change, or any development involving a prospective change,
                 in or affecting the general affairs, management, financial
                 position, stockholders' equity or results of operations of the
                 Company and its subsidiaries, otherwise than as set forth or
                 contemplated in the Prospectus, the effect of which, in any
                 such case described in clause (i) or (ii), is in the judgment
                 of the representatives of the Underwriters so material and
                 adverse as to make it impracticable or inadvisable to proceed
                 with the public offering or the delivery of the Shares

                 the manner contemplated in the Prospectus;

                          (f)              On or after the date hereof there
                 shall not have occurred any of the following: (i) a suspension
                 or material limitation in trading in securities generally on
                 the New York Stock Exchange or on NASDAQ; (ii) a suspension or
                 material limitation in trading in the Company's securities on
                 NASDAQ; (iii) a general moratorium on commercial banking
                 activities declared by either federal or New York or Texas
                 state authorities; or (iv) the outbreak or escalation of
                 hostilities involving the United States or the declaration by
                 the United States of a national emergency or war, if the
                 effect of any such event specified in this clause (iv) in the
                 judgment of the representatives of the Underwriters makes it
                 impracticable or inadvisable to proceed with the public
                 offering or the delivery of the Shares being delivered at such
                 Time of Delivery on the terms and in the manner contemplated
                 in the Prospectus;

                          (g)              The Shares at such Time of Delivery
                 shall have been approved for quotation on NASDAQ subject only

                 from each officer and director of the Company, substantially
                 to the effect set forth in Subsection 5(f) hereof in form and
                 substance satisfactory to you;

                          (i)              The Company shall have furnished or
                 caused to be furnished to you at such Time of Delivery
                 certificates of officers of the Company on behalf of the
                 Company satisfactory to you as to the accuracy of the
                 representations and warranties of the Company herein at and as
                 of such Time of Delivery, as to the performance by the Company
                 of all of their respective obligations hereunder to be
                 performed at or prior to such Time of Delivery, and as to such
                 other matters as you may reasonably request, the Company shall
                 have furnished or caused to be furnished certificates as to
                 the matters set forth in subsections (a) and (e) of this
                 Section and the Company shall have furnished or caused to be
                 furnished to you such other documents as you may reasonably
                 request.

                 8.

                          (a)              The Company will indemnify and hold
                 harmless each Underwriter against any losses, claims, damages
                 or liabilities, joint or several, to which such Underwriter
                 may become subject, under the Act or otherwise, insofar as
                 such losses, claims, damages or liabilities (or actions in

                 with investigating or defending any such action or claim as
                 such expenses are incurred; provided, however, that the
                 Company shall not be liable in any such case to the extent
                 that any such loss, claim, damage or liability arises out of
                 or is based upon an untrue statement or alleged untrue
                 statement or omission or alleged omission made in any

                 the Act or otherwise, insofar as such losses, claims, damages
                 or liabilities (or actions in respect thereof) arise out of or
                 are based upon an untrue statement or alleged untrue statement
                 of a material fact contained in any Preliminary Prospectus,
                 the Registration Statement or the Prospectus, or any amendment
                 or supplement thereto, or arise out of or are based upon the
                 omission or alleged omission to state therein a material fact
                 required to be stated therein or necessary to make the
                 statements therein not misleading, in each case to the extent,
                 but only to the extent, that such untrue statement or alleged
                 untrue statement or omission or alleged omission was made in
                 any Preliminary Prospectus, the Registration Statement or the
                 Prospectus or any such amendment or supplement in reliance
                 upon and in conformity with written information furnished to
                 the Company by such Underwriter through the representatives,
                 expressly for use therein; and will reimburse the Company for
                 any legal or other expenses reasonably incurred by the Company
                 in connection with investigating or defending any such action
                 or claim as such expenses are incurred;

                          (c)              Promptly after receipt by an
                 indemnified party under subsections (a) or (b) above of notice
                 of the commencement of any action, such indemnified party
                 shall, if a claim in respect thereof is to be made against the
                 indemnifying party under such subsection, notify the
                 indemnifying party in writing of the commencement thereof; but
                 the omission so to notify the indemnifying party shall not
                 relieve the indemnifying party from any liability that it may
                 have to any indemnified party otherwise than under such
                 subsection.  In case any such action shall be brought against
                 any indemnified party and it shall notify the indemnifying
                 party of the commencement thereof, the indemnifying party
                 shall be entitled to participate therein and, to the extent
                 that it shall wish, jointly with any other indemnifying party
                 similarly notified, to assume the defense thereof, with
                 counsel satisfactory to such indemnified party (who shall not,
                 except with the consent of the indemnified party, be counsel
                 to the indemnifying party), and, after notice from the
                 indemnifying party to such indemnified party of its election
                 so to assume the defense thereof, the indemnifying party shall
                 not be liable to such indemnified party under such subsection
                 for any legal expenses of other counsel or any other expenses,
                 in each case subsequently incurred by such indemnified party,
                 in connection with the defense thereof other than reasonable
                 costs of investigation.  No indemnifying party shall, without
                 the written consent of the indemnified party, effect the
                 settlement or compromise of, or consent to the entry of any
                 judgment with respect to, any pending or threatened action or
                 claim in respect of which indemnification or





                                     - 15 -
<PAGE>   16
                 contribution may be sought hereunder (whether or not the
                 indemnified party is an actual or potential party to such
                 action or claim) unless such settlement, compromise or
                 judgment (i) includes an unconditional release of the
                 indemnified party from all liability arising out of such
                 action or claim and (ii) does not include a statement as to,
                 or an admission of, fault, culpability or failure to act, by
                 or on behalf of any indemnified party;

                          (d)              If the indemnification provided for
                 in this Section 8 is unavailable to or insufficient to hold
                 harmless an indemnified party under subsections (a) or (b)
                 above in respect of any losses, claims, damages or liabilities
                 (or actions in respect thereof) referred to therein, then each
                 indemnifying party shall contribute to the amount paid or
                 payable by such indemnified party as a result of such losses,
                 claims, damages or liabilities (or actions in respect thereof)
                 in such proportion as is appropriate to reflect the relative
                 benefits received by the Company on the one hand and the
                 Underwriters on the other from the offering of the Shares.
                 If, however, the allocation provided by the immediately
                 preceding sentence is not permitted by applicable law or if
                 the indemnified party failed to give the notice required under
                 subsection (c) above, then each indemnifying party shall
                 contribute to such amount paid or payable by such indemnified
                 party in such proportion as is appropriate to reflect not only
                 such relative benefits but also the relative fault of the
                 Company on the one hand and the Underwriters on the other in
                 connection with the statements or omissions that resulted in
                 such losses, claims, damages or liabilities (or actions in
                 respect thereof), as well as any other relevant equitable
                 considerations.  The relative benefits received by the Company
                 on the one hand and the Underwriters on the other shall be
                 deemed to be in the same proportion as the total net proceeds
                 from the offering (before deducting expenses) received by the
                 Company bears to the total underwriting discounts and
                 commissions received by the Underwriters, as set forth in the
                 table on the cover page of the Prospectus.  The relative fault
                 shall be determined by reference to, among other things,
                 whether the untrue or alleged untrue statement of a material
                 fact or the omission or alleged omission to state a material
                 fact relates to information supplied by the Company on the one
                 hand or the Underwriters on the other and the parties'
                 relative intent, knowledge, access to information and
                 opportunity to correct or prevent such statement or omission.
                 The Company and the Underwriters agree that it would not be
                 just and equitable if contributions pursuant to this
                 subsection (d) were determined by pro rata allocation (even if
                 the Underwriters were treated as one entity for such purpose)
                 or by any other method of allocation which does not take
                 account of the equitable considerations referred to above in
                 this subsection (d).  The amount paid or payable by an
                 indemnified party as a result of the losses, claims, damages
                 or liabilities (or actions in respect thereof) referred to
                 above in this subsection (d) shall be deemed to include any
                 legal or other expenses reasonably incurred by such
                 indemnified party in connection with investigating or
                 defending any such action or claim.  Notwithstanding the
                 provisions of this subsection (d), no Underwriter shall be
                 required to contribute any amount in excess of the amount by
                 which the total price at which the Shares underwritten by it
                 and distributed to the public were offered to the public
                 exceeds the amount of any damages which such Underwriter has
                 otherwise been required to pay by reason of such untrue or
                 alleged untrue statement or omission or alleged omission.  No
                 person guilty of fraudulent misrepresentation (within the
                 meaning of Section 11(f) of the Act) shall be entitled to
                 contribution from any





                                     - 16 -
<PAGE>   17
                 person who was not guilty of such fraudulent
                 misrepresentation.  The Underwriters' obligations in this
                 subsection (d) to contribute are several, in proportion to
                 their respective underwriting obligations, and not joint.

                          (e)              The obligations of the Company under
                 this Section 8 shall be in addition to any liability which the
                 Company may otherwise have and shall extend, upon the same
                 terms and conditions, to each person, if any, who controls any
                 Underwriter within the meaning of the Act; and the obligations
                 of the Underwriters under this Section 8 shall be in addition
                 to any liability which the respective Underwriters may
                 otherwise have and shall extend, upon the same terms and
                 conditions, to each officer and director of the Company
                 (including any person who, with his or her consent, is named
                 in the Registration Statement as about to become a director of
                 the Company) and to each person, if any, who controls the
                 Company within the meaning of the Act.

                 9.

                          (a)              If any Underwriter shall default in
                 its obligation to purchase the Shares that it has agreed to
                 purchase hereunder at Time of Delivery you may in your
                 discretion arrange for you or another party or other parties
                 to purchase such Shares on the terms contained herein.  If
                 within thirty-six hours after such default by any Underwriter
                 you do not arrange for the purchase of such Shares, then the
                 Company shall be entitled to a further period of thirty-six
                 hours within which to procure another party or other parties
                 satisfactory to you to purchase such Shares on such terms.  In
                 the event that, within the respective prescribed periods, you
                 notify the Company that you have so arranged for the purchase
                 of such Shares, or the Company notifies you it has so arranged
                 for the purchase of such Shares, you or the Company shall have
                 the right to postpone Time of Delivery for a period of not
                 more than seven days, in order to effect whatever changes may
                 thereby be made necessary in the Registration Statement or the
                 Prospectus, or in any other documents or arrangements, and the
                 Company agrees to file promptly any amendments to the
                 Registration Statement or the Prospectus which in your opinion
                 may thereby be made necessary.  The term "Underwriter" as used
                 in this Agreement shall include any person substituted under
                 this Section with like effect as if such person had originally
                 been a party to this Agreement with respect to such Shares.

                          (b)              If, after giving effect to any
                 arrangements for the purchase of the Shares of a defaulting
                 Underwriter or Underwriters by you and the Company as provided
                 in subsection (a) above, the aggregate number of such Shares
                 which remains unpurchased does not exceed one-eleventh of the
                 aggregate number of all the Shares to be purchased at such
                 Time of Delivery, then the Company shall have the right to
                 require each non-defaulting Underwriter to purchase the number
                 of Shares which such Underwriter agreed to purchase hereunder
                 at such Time of Delivery and, in addition, to require each
                 non-defaulting Underwriter to purchase its pro rata share
                 (based on the number of Shares which such Underwriter agreed
                 to purchase hereunder) of the Shares of such defaulting
                 Underwriter or Underwriters for





                                     - 17 -
<PAGE>   18
                 which such arrangements have not been made; but nothing herein
                 shall relieve a defaulting Underwriter from liability for its
                 default.

                          (c)              If, after giving effect to any
                 arrangements for the purchase of the Shares of a defaulting
                 Underwriter or Underwriters by you and the Company as provided
                 in subsection (a) above, the aggregate number of such Shares
                 which remains unpurchased exceeds one-eleventh of the
                 aggregate number of all of the Shares to be purchased at such
                 Time of Delivery, or if the Company shall not exercise the
                 right described in subsection (b) above to require
                 non-defaulting Underwriters to purchase Shares of a defaulting
                 Underwriter or Underwriters, then this Agreement (or, with
                 respect to the Second Time of Delivery, the obligations of the
                 Underwriters to purchase and of the Company to sell the
                 Optional Shares) shall thereupon terminate, without liability
                 on the part of any non-defaulting Underwriter or the Company,
                 except for the expenses to be borne by the Company and the
                 Underwriters as provided in Section 6 hereof and the indemnity
                 and contribution agreements in Section 8 hereof; but nothing
                 herein shall relieve a defaulting Underwriter from liability
                 for its default.

                 10.              The respective indemnities, agreements,
representations, warranties and other statements of the Company and the several
Underwriters, as set forth in this Agreement or made by or on behalf of them,
respectively, pursuant to this Agreement, shall remain in full force and
effect, regardless of any investigation (or any statement as to the results
thereof) made by or on behalf of any Underwriter or any controlling person of
any Underwriter, or the Company, or any officer or director or controlling
person of the Company and shall survive delivery of and payment for the Shares.

                 11.              If this Agreement shall be terminated
pursuant to Section 9 hereof, the Company shall not then be under any liability
to any Underwriter except as provided in Sections 6 and 8 hereof; but, if for
any other reason any Shares are not delivered by or on behalf of the Company as
provided herein, the Company will reimburse the Underwriters through you for
all out-of-pocket expenses approved in writing by you, including fees and
disbursements of counsel, reasonably incurred by the Underwriters in making
preparations for the purchase, sale and delivery of the Shares not so
delivered, but the Company shall then be under no further liability to any
Underwriter in respect of the Shares not so delivered except as provided in
Sections 6 and 8 hereof.

                 12.              In all dealings hereunder, you shall act on
behalf of each of the Underwriters, and the parties hereto shall be entitled to
act and rely upon any statement, request, notice or agreement on behalf of any
Underwriter made or given by you jointly or by Morgan Keegan on behalf of you
as the representatives.

         All statements, requests, notices and agreements hereunder shall be in
writing, and if to the Underwriters shall be delivered or sent by mail, telex
or facsimile transmission to you as the representatives in care of Morgan
Keegan & Company, Inc., 50 North Front Street, Memphis, Tennessee 38103,

provided, however, that any notice to an Underwriter pursuant to Section 8(b)
hereof shall be delivered or sent by mail, telex or facsimile transmission to
such Underwriter at its address set forth in its Underwriters' Questionnaire or
telex constituting such Questionnaire, which address will be supplied to the
Company by you on request.  Any such statements, requests, notices or
agreements shall take effect upon receipt thereof.

                 13.              This Agreement shall be binding upon, and
inure solely to the benefit of, the Underwriters and the Company and, to the
extent provided in Sections 8 and 10 hereof, the officers and directors of the
Company and each person who controls the Company or any Underwriter, and their
respective heirs, executors, administrators, successors and assigns, and no
other person shall acquire or have any right under or by virtue of this
Agreement.  No purchaser of any of the Shares from any Underwriter shall be
deemed a successor or assign by reason merely of such purchase.

                 14.              Time shall be of the essence of this
Agreement.

                 15.              THIS AGREEMENT SHALL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF TENNESSEE.

                 16.              This Agreement may be executed by any one or
more of the parties hereto in any number of counterparts, each of which shall
be deemed to be an original, but all such counterparts shall together
constitute one and the same instrument.

         If the foregoing is in accordance with your understanding, please sign
and return to us one for the Company and each of the representatives of the
Underwriters plus one for each counsel and the Custodian, of any counterparts
hereof, and upon the acceptance hereof by you, on behalf of each of the

thereof.

                             FORM OF COMFORT LETTER


         Pursuant to Section 7(d) of the Underwriting Agreement, the
accountants shall furnish letters to the Underwriters to the effect that:

         (i)     They are independent certified public accountants with respect
to the Company and its subsidiaries (including, but not limited to, Hoover,
Ershigs and GL & V/La Valley) within the meaning of the Act and the applicable
published rules and regulations thereunder;

         (ii)    In their opinion, the financial statements and any
supplementary financial information and schedules (and, if applicable,
financial forecasts and/or pro forma financial information) examined by them
and included in the Prospectus or the Registration Statement comply as to form
in all material respects with the applicable accounting requirements of the Act
and the related published rules and regulations thereunder; and, if applicable,
they have made a review in accordance with standards established by the
American Institute of Certified Public Accountants of the unaudited
consolidated interim financial statements, selected financial data, pro forma
financial information, financial forecasts and/or condensed financial
statements derived from audited financial statements of the Company for the
periods specified in such letter, as indicated in their reports thereon, copies
of which have been separately furnished to the representatives of the
Underwriters (the "Representatives");

         (iii)   They have made a review in accordance with standards
established by the American Institute of Certified Public Accountants of the
consolidated statements of income, consolidated balance sheets and consolidated
statements of cash flows included in the Prospectus as indicated in their
reports thereon, copies of which have been separately furnished to the
Representatives and on the basis of specified procedures including inquiries of
officials of the Company who have responsibility for financial and accounting
matters regarding whether the consolidated financial statements referred to in
paragraph (vi)(A)(i) below comply as to form in all material respects with the
applicable accounting requirements of the Act and the related published rules
and regulations, nothing came to their attention that caused them to believe
that the consolidated financial statements do not comply as to form in all
material respects with the applicable accounting requirements of the Act and
the related published rules and regulations;

         (iv)    The unaudited selected financial information with respect to
the consolidated results of operations and financial position of the Company
for the three most recent fiscal years included in the Prospectus agrees with
the corresponding amounts (after restatements where applicable) in the audited
consolidated financial statements for such three fiscal years;

         (v)     They have compared the information in the Prospectus under
selected captions with the disclosure requirements of Regulation S-K and on the
basis of limited procedures specified in such letter nothing came to their
attention as a result of the foregoing procedures that caused them





                                     - 1 -
<PAGE>   23
to believe that this information does not conform in all material respects with
the disclosure requirements of Items 301, 302, 402 and 503(d), respectively, of
Regulation S-K;

         (vi)    On the basis of limited procedures, not constituting an
examination in accordance with generally accepted auditing standards,
consisting of a reading of the unaudited financial statements and other
information referred to below, a reading of the latest available interim
financial statements of the Company and its subsidiaries, inspection of the
minute books of the Company and its subsidiaries since the date of the latest
audited financial statements included in the Prospectus, inquiries of officials
of the Company and its subsidiaries responsible for financial and accounting
matters and such other inquiries and procedures as may be specified in such
letter, nothing came to their attention that caused them to believe that:

                 (A)      (i)     the consolidated statements of income,
         consolidated balance sheets and consolidated statements of cash flows
         included in the Prospectus do not comply as to form in all material
         respects with the applicable accounting requirements of the Act and
         the related published rules and regulations, or (ii) any material
         modifications should be made to the consolidated statements of income,
         consolidated balance sheets and consolidated statements of cash flows
         included in the Prospectus for them to be in conformity with generally
         accepted accounting principles;

                 (B)      any unaudited income statement data and balance sheet
         items included in the Prospectus do not agree with the corresponding
         items in the unaudited consolidated financial statements from which
         such data and items were derived, and any such unaudited data and
         items were not determined on a basis substantially consistent with the
         basis for the corresponding amounts in the audited consolidated
         financial statements included in the Prospectus;

                 (C)      [the unaudited financial statements which were not
         included in the Prospectus but from which were derived any unaudited
         financial statements referred to in clause (A) and] any unaudited
         income statement data and balance sheet items included in the
         Prospectus and referred to in clause (B) were not determined on a
         basis substantially consistent with the basis for the audited
         consolidated financial statements included in the Prospectus;

                 (D)      any unaudited pro forma condensed consolidated
         financial statements included in the Prospectus do not comply as to
         form in all material respects with the applicable accounting
         requirements of the Act and the published rules and regulations
         thereunder or the pro forma adjustments have not been properly applied
         to the historical amounts in the compilation of those statements;

                 (E)      as of a specified date not more than five days prior
         to the date of such letter, there have been any changes in the
         consolidated capital stock (other than issuances of capital stock upon
         exercise of options and stock appreciation rights, upon earn-outs of
         performance shares and upon conversions of convertible securities, in
         each case which were outstanding on the date of the latest financial
         statements included in the Prospectus) or any increase in

         the consolidated long-term debt of the Company and its subsidiaries,
         or any decreases in consolidated net current assets or stockholders'
         equity or other items specified by the Representatives, or any
         increases in any items specified by the Representatives, in each case
         as compared with amounts shown in the latest balance sheet included in
         the Prospectus, except in each case for changes, increases or
         decreases which the Prospectus discloses have occurred or may occur or
         which are described in such letter; and

                 (F)      for the period from the date of the latest financial
         statements included in the Prospectus to the specified date referred
         to in clause (E) there were any decreases in consolidated net revenues
         or operating profit or the total or per share amounts of consolidated
         net income or other items specified by the Representatives, or any
         increases in any items specified by the Representatives, in each case
         as compared with the comparable period of the preceding year and with
         any other period of corresponding length specified by the
         Representatives, except in each case for decreases or increases which
         the Prospectus discloses have occurred or may occur or which are
         described in such letter; and

         (vii)   In addition to the examination referred to in their report(s)
included in the Prospectus and the limited procedures, inspection of minute
books, inquiries and other procedures referred to in paragraphs (iii) and (vi)
above, they have carried out certain specified procedures, not constituting an
examination in accordance with generally accepted auditing standards, with
respect to certain amounts, percentages and financial information specified by
the Representatives, which are derived from the general accounting records of
the Company and its subsidiaries, which appear in the Prospectus, or in Part II
of, or in exhibits and schedules to, the Registration Statement specified by
the Representatives, and have compared certain of such amounts, percentages and
financial information with the accounting records of the Company and its
subsidiaries and have found them to be in agreement.

Denali Incorporated
1360 Post Oak Blvd., Suite 2470
Houston, Texas  77056

Gentlemen:

         Denali Incorporated, a Delaware corporation (the "Company"), has filed
with the Securities & Exchange Commission (the "Commission") a Registration
Statement on Form S-1 under the Securities Act of 1933, as amended (the
"Registration Statement") relating to the proposed sale by the Company in a
public offering of an aggregate of up to 2,100,000 shares of Common Stock (the
"Securities") of the Company. Said Securities are proposed to be sold in a "firm
commitment" underwritten public offering pursuant to a proposed Underwriting
Agreement with Morgan Keegan & Company, Inc. and Rauscher Pierce Refsnes, Inc.
as the representatives of the underwriters named therein (the "Underwriters").
An additional 315,000 shares of Common Stock will be subject to an option from
the Company to the Underwriters, exercisable during a 30-day period after the
date of the Prospectus to cover over-allotments.

         In connection with this opinion, we have examined original, photostatic
or certified copies of such records of the Company, certificates of officers of
the Company and of public officials, and such other documents as we have deemed
relevant. In such examination, we have assumed the genuineness of all
signatures, the authenticity of all documents submitted to us as originals, the
conformity to original documents of all documents submitted to us as certified
or photostatic copies and the authenticity of the originals of such documents.

         Based upon the foregoing and upon such matters of law as we have deemed
necessary and appropriate, we are of the opinion that the Securities proposed to
be sold to the public, pursuant to the Underwriting Agreement proposed to be
entered into by and between the Company and the Underwriters, have been duly and
validly authorized, and upon the delivery of the Securities and payment therefor
pursuant to the terms of the aforesaid Underwriting Agreement, the Securities
will be validly issued, fully paid and nonassessable.

         We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and the reference to us under the caption "Legal
Matters." In giving this consent, we do not admit that we are within the
category of persons whose consent is required under Section 7 of the Securities
Act of 1933, as amended, or the general rules and regulations of the Commission
promulgated thereunder.

                                       Very truly yours,

                                       HUTCHESON & GRUNDY, L.L.P.

         ARTICLE 2 - REVOLVING CREDIT FACILITY

         A.     REVOLVING CREDIT FACILITY

to the conditions of, and in reliance upon the representations and warranties
made under, this Agreement, the Lender shall make Revolving Credit Loans to
each Borrower from time to time from the Funding Date to the Termination Date,
as requested by such Borrower in accordance with the terms of SECTION 2A.2, in
an aggregate principal amount outstanding not to exceed at any time the lesser
of (a) the Revolving Credit Facility, minus the outstanding principal balance
of all Revolving Credit Loans to all other Borrowers, minus the Aggregate
Letter of Credit Reserve, or (b) the Borrowing Base of such Borrower.  It is
expressly understood and agreed that the Lender may and at present intends to
use the lesser of the amounts referred to in the foregoing subclauses (a) and
(b) as a maximum ceiling on Revolving Credit Loans; provided, however, that it
is agreed that should Revolving Credit Loans exceed the ceiling so determined
or any other limitation set forth in this Agreement, such Revolving Credit
Loans shall nevertheless constitute Secured Obligations and, as such, shall be
entitled to all benefits thereof and security therefor.  The principal amount
of any Revolving Credit Loan which is repaid may be reborrowed by the Borrowers
in accordance with the terms of this SECTION 2A.1.  The Lender is hereby
authorized to record each repayment of principal of the Revolving Credit Loans
in its books and records, such books and records constituting prima facie
evidence of the accuracy of the information contained therein.

         Section 2A.2     Manner of Borrowing Revolving Credit Loans.
Borrowings of the Revolving Credit Loans shall be made as follows:

         (a)     Requests for Borrowing.

                 (i)      Prime Rate Revolving Credit Loans.  A request for the
         borrowing of a Prime Rate Revolving Credit Loan shall be made, or
         shall be deemed to be made, in the following manner:





LOAN AND SECURITY AGREEMENT - PAGE 23
<PAGE>   24
                          (A)     any Borrower may request a Prime Rate
                 Revolving Credit Loan by notifying the Lender, before 12:00
                 noon (Dallas, Texas, time) on the proposed borrowing date, of
                 its intention to borrow, specifying the effective date and
                 amount of such proposed Prime Rate Revolving Credit Loan;

                          (B)     whenever a check is presented to the Lender
                 for payment against the Disbursement Account of any Borrower
                 in an amount greater than the then available balance in such
                 account, such presentation shall be deemed to be a request for
                 a Prime Rate Revolving Credit Loan on the date of such notice
                 in an amount equal to the excess of such check over such
                 available balance, and such request shall be irrevocable;

                          (C)     unless payment is otherwise made by a
                 Borrower, the becoming due of any amount required to be paid
                 under this Agreement or any of the Notes as interest shall be
                 deemed to be a request for a Prime Rate Revolving Credit Loan
                 on the due date in the amount required to pay such interest,
                 and such request shall be irrevocable;

                          (D)     unless payment is otherwise made by such
                 Borrower, the maturity of any Secured Obligation required to
                 be paid shall be deemed to be a request for a Prime Rate
                 Revolving Credit Loan on the due date in the amount required
                 to pay such Secured Obligation, and such request shall be
                 irrevocable; and

                          (E)     whenever a drawing is made under a Letter of
                 Credit and such Borrower fails to reimburse the Lender
                 therefor, such failure to reimburse shall be deemed to be a
                 request for a Prime Rate Revolving Credit Loan on the date
                 such drawing is made in the amount so unreimbursed.

                 (ii)     LIBOR Revolving Credit Loans.  Any Borrower may

         time) on the date two Business Days before the day on which the
         requested LIBOR Revolving Credit Loan is to be made, specifying the
         effective date and amount of such LIBOR Revolving Credit Loan and the
         duration of the applicable Interest Period.

                 (iii)    Notice of Borrowing.  Any request for a Prime Rate
         Revolving Credit Loan under SECTION 2A.2(a)(i)(A) or a LIBOR Revolving
         Credit Loan under SECTION 2A.2(a)(ii) (a "Notice of Borrowing") shall
         be made by telephone or in writing (including telecopy) and, in the
         case of any telephonic notice, shall be immediately followed by a
         written confirmation thereof in a form acceptable to the Lender,
         provided that the failure to provide written confirmation shall not
         invalidate any telephonic notice and, if such written confirmation
         differs in any respect from the action taken by the Lender, the
         records of the Lender shall control absent manifest error.





LOAN AND SECURITY AGREEMENT - PAGE 24

payment of the relevant principal, interest or other Secured Obligation, as the
case may be.

         Section 2A.3     Repayment of Revolving Credit Loans.  The Revolving
Credit Loans will be repaid as follows: (a) whether or not any Default or Event
of Default has occurred, the outstanding principal amount of all the Revolving
Credit Loans to each Borrower is due and payable, and shall be repaid by such
Borrower in full together with accrued and unpaid interest to the date of
repayment on such outstanding principal, on the Termination Date; (b) if at any
time the aggregate unpaid principal amount of the Revolving Credit Loans then
outstanding to any Borrower exceeds the lesser of the amounts referred to in
clauses (a) and (b) of SECTION 2A.1 for such Borrower, such Borrower shall
repay the Revolving Credit Loans in an amount sufficient to reduce the
aggregate unpaid principal amount of such Loans by an amount equal to such

payment under such Letter of Credit, whether or not such Borrower would be
entitled to an advance for such amount pursuant to SECTION 2A.1.  At the time
of the issuance of each Letter of Credit, such Borrower shall pay to Lender (A)
a Letter of Credit fee equal to the greater of (1) three percent (3.0%) per

the Lender in the case of a prepayment in full and upon at least five days'

installments of such Term Loan in the inverse order of their maturities,
together with all amounts due under SECTION 3.7 as a result of such prepayment.

hereunder shall be irrevocable, and the amount to be prepaid (including accrued
interest and any prepayment fees) shall be due and payable on the date

         (b)     Mandatory Prepayments.  In the event any Borrower sells any of

such proceeds exceed (i) $10,000 in the case of any single item of Equipment,
or (ii) $50,000 in the aggregate for all such Equipment sold during fiscal
year, shall be paid, immediately upon receipt by such Borrower, to the Lender,
and shall be applied to the principal





LOAN AND SECURITY AGREEMENT - PAGE 28
<PAGE>   29
installments of such Borrower's Equipment Term Loan in the inverse order of
their maturities; no payment is required under this section if the sales
proceeds are less than (i) $10,000 in the case of any single item of Equipment
or (ii) $50,000 in the aggregate for all such Equipment sold during any fiscal
year by all Borrowers.  In the event any Borrower sells any parcel of its Real
Property, the greater of the appraised value of such parcel of Real Property or
any and all amounts received by any Borrower as proceeds from the sale of such
Real Property, net of commissions, taxes, and reasonable legal fees, shall be
paid, immediately upon receipt by such Borrower, to the Lender, and shall be
applied to the principal installments of such Borrower's Real Estate Term Loan
in the inverse order of their maturities.  Together with any such payment, such
Borrower shall pay to the Lender all amounts due under SECTION 3.7 as a result
of such prepayment.  On the prepayment date, such Borrower shall pay interest
on the amount prepaid, accrued to the prepayment date.  Each Borrower shall

with accrued and unpaid interest thereon (and all amounts due under SECTION 3.7

to ARTICLE 11.  Upon receipt of the payments due hereunder, the Lender shall
release all liens and security interests against the Equipment or parcel of
Real Property sold by executing releases and termination statements reasonably
requested by Borrowers.  To the extent this provision conflicts with a similar
provision in any other Loan Document, this provision shall control.

          (a)    (i)      Prime Rate Revolving Credit Loans.  Each Borrower
         will pay interest on the unpaid principal amount of each Prime Rate
         Revolving Credit Loan made to such Borrower for each day from the day
         such Loan was made until such Loan is paid (whether at maturity, by
         reason of acceleration or otherwise), or is converted to a Loan of a
         different Type, at a rate per annum equal to the lesser of (A) the
         Maximum Rate, or (B) the sum of one half of one percent (0.50%) plus
         the Prime Rate, payable monthly in arrears on each Interest Payment
         Date and on the Termination Date.

                 (ii)     LIBOR Revolving Credit Loans.  Each Borrower will pay
         interest on the unpaid principal amount of each LIBOR Revolving Credit
         Loan made to such Borrower for the Interest Period applicable thereto
         at a rate per annum equal to the lesser of (A) the Maximum Rate, or
         (B) the sum of two and three quarters percent (2.75%) plus LIBOR,
         payable in arrears on each Interest Payment Date, on the last day of

LOAN AND SECURITY AGREEMENT - PAGE 29

         otherwise).

                 (iv)     LIBOR Term Loans.  Each Borrower will pay interest on
         each LIBOR Term Loan made to such Borrower for the Interest Period
         applicable thereto at a rate per annum equal to the lesser of (A) the
         Maximum Rate, or (B) the sum of three percent (3.0%) plus LIBOR,
         payable in arrears on each Interest Payment Date, on the last day of

         (b)     Each Borrower shall pay interest on the unpaid principal
amount of each Secured Obligation of such Borrower other than a Loan for each
day from the day such Secured Obligation becomes due and payable until such
Secured Obligation is paid at the rate per annum applicable to Prime Rate
Revolving Credit Loans, payable on demand.

         In the event any Borrower fails to make any interest payment within
five (5) days of the date when due, the Lender may, at its option but without
waiving any of its rights hereunder, make an advance under the Revolving Credit
Facility to pay such interest.

         (c)     From and after the occurrence of an Event of Default, the
unpaid principal amount of each Secured Obligation shall bear interest until

Maximum Rate, or (B) the Default Margin plus the rate otherwise in effect under
SECTION 3.1(a) or (b), payable on demand.  The interest rate provided for in

Obligation and shall continue to accrue at such rate during any proceeding
described in SECTION 11.1(f) or (g).

         (d)     The interest rates provided for in SECTIONS 3.1(a), (b) and
(c) shall be computed on the basis of a year of 360 days and the actual number
of days elapsed; provided, however, any calculation of the Maximum Rate shall
be computed on the basis of the actual days elapsed in a year of 365 or 366
days, as appropriate, unless the Texas Credit Title permits any applicable
interest rate ceiling to be calculated on the basis of a 360-day year and
twelve 30-day months.

         (e)     Notwithstanding anything contained herein, in the Notes or in
any other Loan Documents to the contrary, it is not intended by the Lender to
contract for, charge, receive, collect or apply interest calculated at a rate
in excess of the Maximum Rate.  Further, Lender shall never be deemed to have
contracted for or be entitled to charge, receive, collect or apply as interest
on the Loans, any amount in excess of the amount permitted and calculated at
the Maximum Rate, and, in the event Lender ever contracts for, charges,
receives, collects or applies as interest any amount in excess of the amount
permitted and calculated at the Maximum Rate, such amount which would be
excessive interest shall be applied to the reduction of the unpaid principal
balance of the Loans, and, if the principal balance of the Loans has been paid
in full, any remaining excess shall forthwith be paid to Borrowers.  In
determining whether or not the





LOAN AND SECURITY AGREEMENT - PAGE 30
<PAGE>   31
interest paid or payable under any specific contingency exceeds the Maximum
Rate, Borrowers and Lender shall, to the maximum extent permitted under
applicable law, (i) characterize any non-principal payment (other than payments
which are expressly designated as interest payments hereunder) as an expense,
fee, or premium, rather than as interest, (ii) exclude voluntary prepayments
and the effect thereof, and (iii) spread the total amount of interest
throughout the entire contemplated term of the Loans.

         If, in any month, the Effective Interest Rate, absent the limitation
to the Maximum Rate, would have exceeded the Maximum Rate, then the Effective
Interest Rate for that month shall be the Maximum Rate, and if, in future
months, the Effective Interest Rate would otherwise be less than the Maximum
Rate, then the Effective Interest Rate shall remain at the Maximum Rate until
such time as the amount of interest paid hereunder equals the amount of
interest which would have been paid if the same had not been limited by the
Maximum Rate.  In this connection, in the event that, upon payment in full of
the Secured Obligations, the total amount of interest paid or accrued under the
terms of this Agreement is less than the total amount of interest which would
have been paid or accrued if the Effective Interest Rate had at all times been
in effect, then the Borrowers shall, to the extent permitted by applicable law,
pay to the Lender an amount equal to the difference between (i) the lesser of
(A) the amount of interest which would have been charged if the Maximum Rate
had, at all times, been in effect and (B) the amount of interest which would
have accrued had the Effective Interest Rate, at all times, been in effect, and
(ii) the amount of interest actually paid or accrued under this Agreement.

         In no event shall Chapter 346 of the Texas Finance Code (which
regulates certain revolving loan accounts and revolving tri-party accounts)
apply to any Note.

         Section 3.2      Fees.

         (a)     Commitment Fee.  In connection with and as consideration for
the Lender's commitment hereunder, subject to the terms hereof, to lend to the
Borrowers under the Revolving Credit Facility, the Borrowers shall, jointly and
severally, pay a fee to the Lender, from the Funding Date until the Termination
Date, in an amount equal to 0.375% per annum of the average daily unused
portion of the Revolving Credit Facility, payable monthly in arrears on the
first day of each month and on the date of any permanent reduction in the
Revolving Credit Facility.

         (b)     Closing Fee.  Subject to SECTION 3.1(e), the Borrowers shall
pay to the Lender a closing fee in the amount of $167,470 in connection with
the establishment of the Revolving Credit Facility and in consideration of the
commitment to make the Loans made under this Agreement and in order to
compensate the Lender for the costs associated with structuring, processing,
approving and closing the Revolving Credit Facility and the Loans, but
excluding expenses for which the Borrowers have agreed elsewhere in this
Agreement to reimburse the Lender.  One half of the closing fee shall be due
and payable on the Agreement Date and the balance of the closing fee shall be
due and payable on the earlier of the Funding Date or the date this Agreement
terminates pursuant to SECTION 2A.7 because either (i) Borrowers have





LOAN AND SECURITY AGREEMENT - PAGE 31
<PAGE>   32
terminated this Agreement pursuant to such section or (ii) the Lender has
terminated this Agreement pursuant to such section because Borrowers have not
met all of the conditions set forth in SECTIONS 4.1 AND 4.2 or because no
Borrower has requested a Loan.

         (c)     Administration Fee.  For services performed by the Lender in
connection with its continuing administration hereof, subject to SECTION
3.1(e), the Borrowers shall, jointly and severally, pay to the Lender a
quarterly fee of $6,250, payable quarterly in advance on the Funding Date and
on the first day of each quarter thereafter, and continuing so long as any Loan
shall remain outstanding or the Revolving Credit Facility shall not have been
terminated.

         (d)     General.  All fees shall be fully earned by the Lender when
due and payable and, except as otherwise set forth herein, shall not be subject
to refund or rebate.  To the extent permitted under applicable law, the
Borrowers and Lender agree that all fees are for compensation for services and
are not, and shall not be deemed to be, interest or a charge for the use of
money.

         Section 3.3      Notice of Conversion or Continuation of Loans.
Whenever any Borrower desires, subject to the provisions of SECTION 3.4, to
convert an outstanding Revolving Credit Loan or Term Loan into a Loan of a
different Type provided for in this Agreement or to continue all or a portion
of an outstanding LIBOR Revolving Credit Loan or LIBOR Term Loan for a
subsequent Interest Period, such Borrower shall notify the Lender (which notice
shall be irrevocable) in writing (including telecopy) not later than 2:00 p.m.
(Dallas, Texas, time) on the date two Business Days before the day on which a
proposed conversion of a LIBOR Loan into a Prime Rate Loan is to be effective
(which effective date shall be the last day of the Interest Period applicable
to such LIBOR Loan) and two Business Days before the day on which a proposed
conversion of a Prime Rate Loan into, or continuation of a LIBOR Loan as, a
LIBOR Loan is to be effective (and such effective date of any continuation
shall be the last day of the Interest Period for such LIBOR Loan).  Each such
notice (a "Notice of Conversion or Continuation") shall (a) identify the Loan
to be converted or continued, including the Type thereof, the aggregate
outstanding principal balance thereof and, in the case of a LIBOR Loan, the
last day of the Interest Period therefor, (b) specify the effective date of
such conversion or continuation, (c) specify the principal amount of such Loan
to be converted or continued and, if converted, the Type or Types of Loan into
which conversion of such principal amount or specified portions thereof is to
be made, and (d) in the case of any conversion into or continuation as a LIBOR
Loan, the Interest Period to be applicable thereto.

         Section 3.4.     Conversion or Continuation.  Provided that no Event
of Default shall have occurred and be continuing (but subject to the provisions
of SECTIONS 3.5 and 3.6), any Borrower may request that all or any part of any
outstanding Loan of one Type (a) be converted into a Loan or Loans of any other
Type provided for in this Agreement, or (b) be continued as a Loan or Loans of
the same Type, in the same aggregate principal amount, on any Business Day
(which, in the case of a conversion or continuation of a LIBOR Loan, shall be
the last day of the Interest Period applicable to such LIBOR Loan), upon notice
(which notice shall be irrevocable) given in





LOAN AND SECURITY AGREEMENT - PAGE 32
<PAGE>   33
accordance with SECTION 3.3, provided that nothing in this ARTICLE 3 shall be
construed to permit the conversion of a Revolving Credit Loan to a Term Loan or
vice versa.

         Section 3.5      Duration of Interest Periods; Maximum Number of LIBOR
Loans; Minimum Increments.

         (a)     Subject to the provisions of the definition of "Interest
Period", the duration of each Interest Period applicable to a LIBOR Loan shall
be as specified in the applicable Notice of Borrowing or Notice of Conversion
or Continuation.  Any Borrower may elect a subsequent Interest Period to be
applicable to any LIBOR Loan by giving a Notice of Conversion or Continuation
with respect to such Loan in accordance with SECTION 3.3.

         (b)     If the Lender does not receive a Notice of Conversion or
Continuation in accordance with SECTION 3.3 with respect to the continuation of
a LIBOR Loan within the applicable time limits specified in SECTION 3.3, or if,
when such notice must be given, an Event of Default exists or such Type of Loan
is not available, such Borrower shall be deemed to have elected to convert such
LIBOR Loan in whole into a Prime Rate Loan on the last day of the Interest
Period therefor.

         (c)     Notwithstanding the foregoing, no Borrower may select an
Interest Period that would end, but for the provisions of the definition
"Interest Period," after the Termination Date.

         (d)     In no event shall there be more than five (5) LIBOR Loans
outstanding hereunder at any time.  For the purpose of this subsection (d),
each LIBOR Revolving Credit Loan and each LIBOR Term Loan having a distinct
Interest Period shall be deemed to be a separate Loan hereunder.

         (e)     Each LIBOR Loan shall be in a minimum amount of $500,000 or
increments of $1,000 in excess thereof.

         Section 3.6      Changed Circumstances.

         (a)     If the introduction of or any change in or in the
interpretation of (in each case, after the date hereof) any law or regulation
makes it unlawful, or any Governmental Authority asserts, after the date
hereof, that it is unlawful, for the Lender to perform its obligations
hereunder to make or maintain LIBOR Loans, the Lender shall notify the
Borrowers of such event, and the right of the Borrowers to select LIBOR Loans
for any subsequent Interest Period or in connection with any subsequent
conversion of any Loan shall be suspended until the Lender shall notify the
Borrowers that the circumstances causing such suspension no longer exist, and,
if it is unlawful to maintain LIBOR Loans, the Borrowers shall forthwith prepay
in full all LIBOR Revolving Credit Loans then outstanding and shall convert
each LIBOR Term Loan into a Prime Rate Term Loan, and shall pay all interest
accrued thereon through the date of such prepayment or conversion; provided,
that if the date of such repayment or proposed conversion is not the last





LOAN AND SECURITY AGREEMENT - PAGE 33
<PAGE>   34
day of the Interest Period applicable to such LIBOR Loans, the Borrowers shall
also pay any amount due pursuant to SECTION 3.7.

         (b)     If the Lender shall, prior to the disbursement of any
requested Revolving Credit Loan or the effective date of any conversion or
continuation of an existing Loan to be made or continued as or converted into a
LIBOR Loan (each such requested Revolving Credit Loan made and Loan to be
converted or continued, a "Pending Loan"), notify the Borrowers that LIBOR will
not adequately reflect the cost to the Lender of making or funding such Pending
Loan as a LIBOR Loan or that the Interbank Offered Rate is not determinable
from any interest rate reporting service of recognized standing, then the right
of the Borrowers to select LIBOR Loans for such Pending Loan, any subsequent
Revolving Credit Loan, or in connection with any subsequent conversion or
continuation of any Loan, shall be suspended until the Lender shall notify the
Borrowers that the circumstances causing such suspension no longer exist, and
each Loan comprising each Pending Loan and each such subsequent Loan requested
to be made, continued or converted shall be made or continued as or converted
into a Prime Rate Loan.

         Section 3.7      Payments Not at End of Interest Period; Failure to
Borrow.  If for any reason any payment of principal with respect to any LIBOR
Loan is made on any day prior to the last day of the Interest Period applicable
to such LIBOR Loan or, after having given a Notice of Borrowing with respect to
any Revolving Credit Loan to be comprised of LIBOR Revolving Credit Loans or a
Notice of Conversion or Continuation with respect to any Loan to be continued
as or converted into a LIBOR Loan, such Loan is not made or is not continued as
or converted into a LIBOR Loan due to a Borrower's failure to borrow or to
fulfill the applicable conditions set forth in ARTICLE 4, such Borrower shall
pay to the Lender, in addition to any other amounts that may be due under this
Agreement, an amount (if a positive number) computed pursuant to the following
formula:


                 L        =       (R - T) x P x D
                              -------------------------
                                       360

                 L        =       amount payable

                 R        =       interest rate applicable to the LIBOR Loan
unborrowed or prepaid

                 T        =       effective interest rate per annum at which
any readily marketable bonds or other obligations of the United States,
selected at the Lender's sole discretion, maturing on or near the last day of
the then applicable or requested Interest Period for such Loan and in
approximately the same amount as such Loan, can be purchased by the Lender on
the day of such payment of principal or failure to borrow

                 P        =       the amount of principal paid or the amount of
the requested Loan

                 D        =       the number of days remaining in the Interest
Period as of the date of such payment or the number of days in the requested
Interest Period





LOAN AND SECURITY AGREEMENT - PAGE 34
<PAGE>   35
Such Borrower shall pay such amount upon presentation by the Lender of a
statement setting forth the amount and the Lender's calculation thereof
pursuant hereto, which statement shall be deemed true and correct absent
manifest error.

         Section 3.8      Increased Costs and Reduced Returns.  The Borrowers
agree that if any law now or hereafter in effect and whether or not presently
applicable to the Lender or any request, guideline or directive of any
Governmental Authority (whether or not having the force of law and whether or
not failure to comply therewith would be unlawful) or the interpretation or
administration thereof by any Governmental Authority, shall either (a)(i)
impose, affect, modify or deem applicable any reserve, special deposit, capital
maintenance or similar requirement against any Loan, (ii) impose on the Lender
any other condition regarding any Loan, this Agreement, the Notes or the
facilities provided hereunder, or (iii) result in any requirement regarding
capital adequacy (including any risk-based capital guidelines) affecting the
Lender being imposed or modified or deemed applicable to the Lender, or (b)
subject the Lender to any taxes on the recording, registration, notarization or
other formalization of the Loans or the Notes, and the result of any event
referred to in clause (a) or (b) above shall be to increase the cost to the
Lender of making, funding or maintaining any Loan or to reduce the amount of
any sum receivable by the Lender or the Lender's rate of return on capital with
respect to any Loan to a level below that which the Lender could have achieved
but for such imposition, modification or deemed applicability (taking into
consideration the Lender's policies with respect to capital adequacy) by an
amount deemed by Lender (in the exercise of its discretion) to be material,
then, upon demand by the Lender, the Borrowers shall immediately pay to the
Lender additional amounts which shall be sufficient to compensate the Lender
for such increased cost, tax or reduced rate of return.  A certificate of the
Lender to the Borrowers claiming compensation under this SECTION 3.8 shall be
final, conclusive and binding on all parties for all purposes in the absence of
manifest error.  Such certificate shall set forth the nature of the occurrence
giving rise to such compensation, the additional amount or amounts to be paid
to it hereunder, and the method by which such amounts were determined.  In
determining such amount, the Lender may use any reasonable averaging and
attribution methods.

         Section 3.9      Manner of Payment.  (a)  Each payment (including
prepayments) by each Borrower on account of the principal of or interest on the
Loans or of any fee or other amounts payable to the Lender under this Agreement
or any Note shall be made not later than 1:30 p.m. (Dallas, Texas, time) on the
date specified for payment under this Agreement (or if such day is not a
Business Day, the next succeeding Business Day) to the Lender at the Lender's
Office, in Dollars, in immediately available funds and shall be made without
any set-off, counterclaim or deduction whatsoever.

         (b)     Each Borrower hereby irrevocably authorizes the Lender and
each Affiliate of the Lender to charge any account of any Borrower maintained
with the Lender or such Affiliate with such amounts as may be necessary from
time to time to pay any Secured Obligations which are not paid when due.





LOAN AND SECURITY AGREEMENT - PAGE 35
<PAGE>   36
         Section 3.10     Statements of Account.  The Lender will account to
the Borrowers within 30 days after the end of each calendar month with a
statement of Loans, charges and payments made pursuant to this Agreement during
such calendar month, and such account rendered by the Lender shall be deemed an
account stated as between the Borrowers and the Lender and shall be deemed
final, binding and conclusive unless the Lender is notified by the Borrowers in
writing to the contrary within 60 days after the date such account is delivered
to the Borrowers, save for manifest error.  Any such notice shall be deemed an
objection only to those items specifically objected to therein.  Failure of the
Lender to render such account shall in no way affect its rights hereunder.

         Section 3.11     Termination of Agreement.  On the Termination Date,
the Borrowers shall pay to the Lender, in same day funds, an amount equal to
the aggregate amount of all Loans outstanding on such date, together with
accrued interest thereon, all fees payable pursuant to SECTION 3.2 accrued from
the date last paid through the effective date of termination, any amounts
payable to the Lender pursuant to the other provisions of this Agreement,
including, without limitation, SECTIONS 3.7, 3.8, 11.2, 12.2 and 12.3, any and
all other Secured Obligations then outstanding, and an amount equal to the
Aggregate Letter of Credit Reserve to be held by the Lender as cash collateral
security for the payment of and to be applied to the payment of any amounts
which may thereafter become due with respect to any Letter of Credit, and
provide the Lender with an indemnification agreement in form and substance
satisfactory to the Lender with respect to returned and dishonored items and
such other matters as the Lender shall require.  Upon 60 days prior written
notice to the Lender, the Borrowers may terminate this Agreement prior to the
date this Agreement would otherwise terminate, upon (i) payment of all Secured
Obligations, (ii) the fulfillment of all of the requirements set forth in the
previous sentence, and (iii) the payment of an early termination fee computed
as follows:  (A) if such termination occurs on or prior to the first
anniversary of the Funding Date, 1.0% of the sum of (i) the Revolving Credit
Facility plus (ii) the sum of the outstanding principal balances of all Term
Loans as of such early termination date plus (iii) the sum of all principal
prepayments made on all Term Loans during the 90-day period immediately
preceding such early termination date, (B) if such termination occurs after the
first anniversary of the Funding Date but on or prior to the second anniversary
of the Funding Date, 0.75% of the sum of (i) the Revolving Credit Facility plus
(ii) the sum of the outstanding principal balances of all Term Loans as of such
early termination date plus (iii) the sum of all principal prepayments made on
all Term Loans during the 90-day period immediately preceding such early
termination date, and (C) if such termination occurs at any time thereafter,
0.50% of the sum of (i) the Revolving Credit Facility plus (ii) the sum of the
outstanding principal balances of all Term Loans as of such early termination
date plus (iii) the sum of all principal prepayments made on all Term Loans
during the 90-day period immediately preceding such early termination date.  No
early termination fee will apply if (i) the Loans are financed by another
division of the Lender or (ii) if the Agreement is terminated pursuant to
SECTION 2A.7.

applicable to it and in compliance with all other applicable laws relating to
it, including, without being limited to, all Environmental Laws and all
occupational health and safety laws applicable to such Borrower or its

Effect and in respect of which adequate reserves have been established on the
books of such Borrower.

state and local taxes and foreign national, provincial and local taxes for all
fiscal years and portions thereof since the organization of such Borrower are

Borrower has any material liabilities, contingent or otherwise, and there were

incurred by such Borrower or any Related Company.

         (p)     Absence of Defaults.  No Borrower is in material default under
its articles or certificate of incorporation or by-laws, and no event has
occurred which has not been remedied, cured or waived (i) that constitutes an

Borrower or any of its properties may be bound or which would require such
Borrower to make any payment thereunder prior to the scheduled maturity date
therefor.

Borrower and furnished to the Lender were, at the time the same were so
furnished, complete and correct in all material respects to the extent
necessary to give the recipient a true and accurate knowledge of the subject
matter.  No fact is known to any Borrower which has had, or may in the future
have (so far as such Borrower can foresee), a Materially Adverse Effect which
has not been set forth in the financial statements or disclosure delivered
prior to the Funding Date, in each case referred to in SECTION 5.1(m), or in
such written information, reports or other papers or data or otherwise
disclosed in writing to the Lender prior to the Funding Date.  No document
furnished or written statement made to the Lender by any Borrower in connection
with the negotiation, preparation or execution of this Agreement or any of the

to the creditworthiness of any Borrower or omits or will omit to state a
material fact necessary in order to make the statements contained therein not
misleading.

(including contingent, subordinated, unmatured and unliquidated liabilities) as

able to meet its debts as they mature and has adequate capital to conduct the
business in which it is or proposes to be engaged.

         (s)     Status of Receivables.  Each Receivable reflected in the
computations included in any Borrowing Base Certificate meets the criteria
enumerated in the definition of Eligible Receivables, except as disclosed in

Equipment or creates Receivables, or to which instruments in payment of
Receivables are made payable, are listed on SCHEDULE 5.1(w).

         and the Lender is hereby granted a license or sublicense and all other
         rights as may be necessary, appropriate or desirable to use the
         Intellectual Property in connection with the foregoing, and the rights
         of each Borrower under all licenses and franchise agreements shall
         inure to the Lender's benefit (provided, however, that any use of any
         federally registered trademarks as to any goods shall be subject to

         the possession thereof, to repossess the Collateral and to sell the
         Collateral or any part thereof in one or more parcels at public or
         private sale, at any location chosen by the Lender, for cash, on

become due under the Letter of Credit Facility, and

         (d)     Fourth:  the balance (if any) of such proceeds shall be paid
to the Borrowers or, subject to any duty imposed by law or otherwise, to
whomsoever is entitled thereto.

         (a)     Rights Cumulative.  The rights and remedies of the Lender
under this Agreement, the Note and each of the Loan Documents shall be
cumulative and not exclusive of any rights or remedies which it or they would
otherwise have.  In exercising such rights and remedies, the Lender may be
selective and no failure or delay by the Lender in exercising any right shall
operate as a waiver of such right nor shall any single or partial exercise of
any power or right preclude its other or further exercise or the exercise of
any other power or right.

severally, waive any right to require any marshalling of assets and any similar
right.

         (c)     Limitation of Liability.  Nothing contained in this ARTICLE 11
or elsewhere in this Agreement or in any of the Loan Documents shall be
construed as requiring or obligating the Lender or any agent or designee of the
Lender to make any demand or to make any inquiry as to the nature or
sufficiency of any payment received by it or to present or file any claim or
notice or take any action with respect to any Receivable or any other
Collateral or the moneys due or to become due thereunder or in connection
therewith or to take any steps necessary to preserve any rights against prior
parties, and neither the Lender nor any of its agents or designees shall have
any liability to any Borrower for actions taken pursuant to this ARTICLE 11,
any other provision of this Agreement or any of the Loan Documents, so long as
the Lender or such agent or designee shall act reasonably and in good faith.

         (d)     Appointment of Receiver.  In any action under this ARTICLE 11,
the Lender shall be entitled to the appointment of a receiver, without notice
of any kind whatsoever, to take possession of all or any portion of the
Collateral and to exercise such power as the court shall confer upon such
receiver.

Borrower, for the purposes set forth in SECTION 11.2(c)(vi) and for the purpose
of enabling the Lender to realize on the Collateral and to permit any purchaser
of any portion of the Collateral through a foreclosure sale or any other
exercise of the Lender's rights and remedies under the Loan Documents to use,
sell or otherwise dispose of the Collateral bearing any such trademark.  Such

The foregoing shall not be construed to limit any other provisions of the Loan
Documents regarding costs and expenses to be paid by the Borrowers.  The
Borrowers hereby authorize the Lender to debit their respective loan accounts
(by increasing the principal amount of the Revolving Credit Loan) in the amount
of any such costs and expenses owed by the Borrowers when due.

         Section 12.3     Stamp and Other Taxes.  Each Borrower will pay any
and all stamp, registration, recordation and similar taxes, fees or charges and
shall indemnify the Lender against any and all liabilities with respect to or

or charges, which may be payable or determined to be payable in connection with
the execution, delivery, performance or enforcement of this Agreement and any
of the Loan Documents or the perfection of any rights or security interest
thereunder.

         Section 12.4     Set-off.  In addition to any rights now or hereafter
granted under applicable law, and not by way of limitation of any such rights,
upon and after the occurrence of any Default or Event of Default, the Lender
and any participant with the Lender in the Loans are hereby authorized by each
Borrower at any time or from time to time, without notice to such Borrower or
to any other Person, any such notice being hereby expressly waived, to set off
and to appropriate and to apply any and all deposits (general or special, time
or demand, including, but not limited to, indebtedness evidenced by
certificates of deposit, whether matured or unmatured) and any other
indebtedness at any time held or owing by the Lender or any participant to or
for the credit or the account of any Borrower against and on account of the
Secured Obligations irrespective or whether or not (a) the Lender shall have
made any demand under this Agreement or any of the Loan Documents, or (b) the
Lender shall have declared any or all of the Secured Obligations to be due and
payable as permitted by SECTION 11.2 and although such Secured Obligations
shall be contingent or unmatured.

         Section 12.5     Litigation.  TO THE EXTENT PERMITTED BY APPLICABLE
LAW, LENDER AND EACH BORROWER HEREBY KNOWINGLY, INTENTIONALLY AND VOLUNTARILY
WAIVE TRIAL BY JURY IN ANY ACTION OR PROCEEDING OF ANY KIND OR NATURE IN ANY
COURT IN WHICH AN ACTION MAY BE COMMENCED BY OR AGAINST ANY BORROWER OR THE
LENDER ARISING OUT OF THIS AGREEMENT, THE COLLATERAL OR ANY ASSIGNMENT THEREOF
OR BY REASON OF ANY OTHER CAUSE OR DISPUTE WHATSOEVER BETWEEN ANY BORROWER AND
THE LENDER OF ANY KIND OR NATURE.  EACH BORROWER AND THE LENDER HEREBY AGREE
THAT THE FEDERAL COURT OF THE NORTHERN DISTRICT OF TEXAS OR, AT THE OPTION OF
THE LENDER, ANY COURT IN WHICH





LOAN AND SECURITY AGREEMENT - PAGE 77
<PAGE>   78
THE LENDER SHALL INITIATE LEGAL OR EQUITABLE PROCEEDINGS AND WHICH HAS SUBJECT
MATTER JURISDICTION OVER THE MATTER IN CONTROVERSY AND WHICH SITS IN A
JURISDICTION IN WHICH A BORROWER TRANSACTS BUSINESS SHALL HAVE NON-EXCLUSIVE
JURISDICTION TO HEAR AND DETERMINE ANY CLAIMS OR DISPUTES BETWEEN ANY BORROWER
AND THE LENDER, PERTAINING DIRECTLY OR INDIRECTLY TO THIS AGREEMENT OR THE LOAN
DOCUMENTS OR TO ANY MATTER ARISING THEREFROM.  EACH BORROWER EXPRESSLY SUBMITS
AND CONSENTS IN ADVANCE TO SUCH JURISDICTION IN ANY ACTION OR PROCEEDING
COMMENCED IN SUCH COURTS, HEREBY WAIVING PERSONAL SERVICE OF THE SUMMONS AND
COMPLAINT OR OTHER PROCESS OR PAPERS ISSUED THEREIN AND AGREEING THAT SERVICE
OF SUCH SUMMONS AND COMPLAINT OR OTHER PROCESS OR PAPERS MAY BE MADE BY
REGISTERED OR CERTIFIED MAIL ADDRESSED TO SUCH BORROWER AT THE ADDRESS SET
FORTH IN SECTION 12.1(b), WHICH SERVICE SHALL BE DEEMED MADE UPON RECEIPT
THEREOF.  THE NON- EXCLUSIVE CHOICE OF FORUM SET FORTH IN THIS SECTION SHALL
NOT BE DEEMED TO PRECLUDE THE ENFORCEMENT OF ANY JUDGMENT OBTAINED IN SUCH
FORUM OR THE TAKING OF ANY ACTION UNDER THIS AGREEMENT TO ENFORCE THE SAME IN
ANY APPROPRIATE JURISDICTION.

         Section 12.6     Reversal of Payments.  To the extent any Borrower
makes a payment or payments to the Lender or the Lender receives any payment or
proceeds of the Collateral for any Borrower's benefit, which payment(s) or
proceeds or any part thereof are subsequently invalidated, declared to be
fraudulent or preferential, set aside and/or required to be repaid to a
trustee, receiver or any other party under any bankruptcy law, state or federal
law, common law or equitable cause, then, the Lender shall have the continuing
and exclusive right to apply, reverse and re-apply any and all payments to any
portion of the Secured Obligations, and, to the extent of such payment or
proceeds received, the Secured Obligations or part thereof intended to be
satisfied shall be revived and continued in full force and effect, as if such
payment or proceeds had not been received by the Lender.

         Section 12.7     Injunctive Relief.  Each Borrower recognizes that, in
the event any Borrower fails to perform, observe or discharge any of its
obligations or liabilities under this Agreement, any remedy of law may prove to
be inadequate relief to the Lender; therefore, each Borrower agrees that the
Lender, at the Lender's option, shall be entitled to temporary and permanent
injunctive relief in any such case without the necessity of proving actual
damages.

         Section 12.8     Accounting Matters.  All financial and accounting
calculations, measurements and computations made for any purpose relating to
this Agreement, including, without limitation, all computations utilized by
each Borrower to determine whether it is in compliance with any covenant
contained herein, shall, unless there is an express written direction or
consent by the Lender to the contrary, be performed in accordance with GAAP.

         Section 12.9     Assignment; Participation.  All the provisions of
this Agreement shall be binding upon and inure to the benefit of the parties
hereto and their respective successors and





LOAN AND SECURITY AGREEMENT - PAGE 78

assigns, except that no Borrower may assign or transfer any of its rights under
this Agreement.  The Lender may assign to one or more Persons reasonably
satisfactory to Borrowers, or sell participations to one or more Persons
reasonably satisfactory to Borrowers in, all or a portion of its rights and
obligations hereunder and under the Notes and, in connection with any such
assignment or sale of a participation, may assign its rights and obligations
under the Security Documents.  The Lender may, in connection with any
assignment or proposed assignment or sale or proposed sale of a participation,
disclose to the assignee or proposed assignee or participant or proposed
participant any information relating to the Borrowers furnished to the Lender
by or on behalf of the Borrowers.

         Section 12.10    Amendments.  Any term, covenant, agreement or
condition of this Agreement or any of the other Loan Documents may be amended
or waived and any departure therefrom may be consented to if, but only if, such
amendment, waiver or consent is in writing signed by the Lender and, in the
case of an amendment, by the Borrowers.  Unless otherwise specified in such
waiver or consent, a waiver or consent given hereunder shall be effective only
in the specific instance and for the specific purpose for which given.

         Section 12.11    Performance of the Borrowers' Duties.  Each
Borrower's obligations under this Agreement and each of the Loan Documents
shall be performed by such Borrower at its sole cost and expense.  If any
Borrower shall fail to do any act or thing which it has covenanted to do under
this Agreement or any of the Loan Documents, the Lender may (but shall not be
obligated to) do the same or cause it to be done either in the name of the
Lender or in the name and on behalf of such Borrower, and each Borrower hereby
irrevocably authorizes the Lender so to act.

         Section 12.12    Indemnification.  Each Borrower, jointly and
severally, shall indemnify, defend, and save harmless Lender and its officers,
directors, employees, agents, and attorneys, and each of them (the "Indemnified
Parties") from and against all claims, actions, suits, and other legal
proceedings, damages, costs, interest, charges, counsel fees, and other
expenses and penalties which any of the Indemnified Parties may sustain or
incur by reason of or arising out of (i) the execution and delivery of this
Agreement or any of the Loan Documents, (ii) the consummation of the
transactions contemplated thereby or hereby, (iii) the exercise by the Lender
of any right or remedy granted to it under this Agreement or any of the Loan
Documents, (iv) any claim, and the prosecution or defense thereof, arising out
of or in any way connected with this Agreement or any of the Loan Documents,
(v) the collection or enforcement of the Secured Obligations or any of them,
(vi) any untrue statement or alleged untrue statement of any material fact by
any Borrower or any Affiliate in any document or schedule filed with the
Securities and Exchange Commission or any other governmental body, (vii) any
omission or alleged omission to state any material fact required to be stated
in any document or schedule set forth in clause (vi) of this SECTION 12.12 or
necessary to make the statements made therein not misleading in light of the
circumstances under which made, or (viii) any acts or omissions, or alleged
acts or omissions of any Borrower, any Affiliate, or their agents related to
the acquisition, purchase, or sale of the securities or assets of any such
Person, or the financing thereof, which are alleged to violate any federal
securities law or any law of any other jurisdiction applicable thereto, other
than losses resulting from such Indemnified Party's gross negligence or willful





LOAN AND SECURITY AGREEMENT - PAGE 79

misconduct, BUT SPECIFICALLY INCLUDING ANY AND ALL LOSSES ARISING FROM ANY
INDEMNIFIED PARTY'S ORDINARY NEGLIGENCE.

         Section 12.13    All Powers Coupled with Interest.  All powers of
attorney and other authorizations granted to the Lender and any Persons
designated by the Lender pursuant to any provisions of this Agreement or any of
the Loan Documents shall be deemed coupled with an interest and shall be
irrevocable so long as any of the Secured Obligations remain unpaid or
unsatisfied or the Revolving Credit Facility has not been terminated.

         Section 12.14    Survival.  Notwithstanding any termination of this
Agreement, (a) until all Secured Obligations have been paid in full and the
Revolving Credit Facility terminated, the Lender shall retain its Security
Interest and shall retain all rights under this Agreement and each of the
Security Documents with respect to the Collateral as fully as though this
Agreement had not been terminated, and (b) the indemnities to which the Lender
is entitled under the provisions of this ARTICLE 12 and any other provision of
this Agreement and the Loan Documents shall continue in full force and effect
and shall protect the Lender against events arising after such termination as
well as before.

         Section 12.15    Severability of Provisions.  Any provision of this
Agreement or any other Loan Document which is prohibited or unenforceable in
any jurisdiction shall, as to such jurisdiction, be ineffective only to the
extent of such prohibition or unenforceability without invalidating the
remainder of such provision or the remaining provisions hereof or thereof or
affecting the validity or enforceability of such provision in any other
jurisdiction.

         Section 12.16    Governing Law.  This Agreement and the Notes shall be
construed in accordance with and governed by the law of the State of Texas.

         Section 12.17    Counterparts.  This Agreement may be executed in any
number of counterparts and by different parties hereto in separate
counterparts, each of which when so executed shall be deemed to be an original
and shall be binding upon all parties, their successors and assigns, and all of
which taken together shall constitute one and the same agreement.

         Section 12.18    Reproduction of Documents.  This Agreement, each of
the Loan Documents and all documents relating thereto, including, without
limitation, (a) consents, waivers and modifications that may hereafter be
executed, (b) documents received by the Lender, and (c) financial statements,
certificates and other information previously or hereafter furnished to the
Lender, may be reproduced by the Lender by any photographic, photostatic,
microcard, microfilm, miniature photographic or other similar process, and the
Lender may destroy any original document so reproduced.  Each party hereto
stipulates that, to the extent permitted by applicable laws any such
reproduction shall be as admissible in evidence as the original itself in any
judicial or administrative proceeding (whether or not the original shall be in
existence and whether or not such reproduction was made by such Lender in the
regular course of business), and any enlargement, facsimile or further
reproduction of such reproduction shall likewise be admissible in evidence.





LOAN AND SECURITY AGREEMENT - PAGE 80
<PAGE>   81
         Section 12.19     Funds Transfer Services.

         (a)     Each Borrower acknowledges that the Lender has made available
to it a description of security procedures regarding funds transfers executed
by the Lender or an affiliate bank at the request of such Borrower (the
"SECURITY PROCEDURES"), a copy of which is attached hereto as EXHIBIT D.  The
Borrowers and the Lender agree that the Security Procedures are commercially
reasonable.  Each Borrower further acknowledges that the full scope of the
Security Procedures which the Lender or such affiliate bank offers and strongly
recommends for funds transfers is available only if such Borrower communicates
directly with the Lender or such affiliate bank as applicable in accordance
with said procedures.  If such Borrower attempts to communicate by any other
method or otherwise not in accordance with the Security Procedures, the Lender
or such affiliate bank, as applicable, shall not be required to execute such
instructions, but if the Lender or such affiliate bank, as applicable, does so,
such Borrower will be deemed to have refused the Security Procedures that the
Lender or such affiliate bank, as applicable, offers and strongly recommends,
and such Borrower will be bound by any funds transfer, whether or not
authorized, which is issued in such Borrower's name and accepted by the Lender
or such affiliate bank, as applicable, in good faith.  The Lender or such
affiliate bank, as applicable, may modify the Security Procedures at such time
or times and in such manner as the Lender or such affiliate bank, as
applicable, in its sole discretion, deems appropriate to meet prevailing
standards of good banking practice.  By continuing to use the Lender's or such
affiliate bank's, as applicable, wire transfer services after receipt of any
modification of the Security Procedures, each Borrower agrees that the Security
Procedures, as modified, are likewise commercially reasonable.  Each Borrower
further agrees to establish and maintain procedures to safeguard the Security
Procedures and any information related thereto.

         (b)     The Lender or such affiliate bank, as applicable, will
generally use the Fedwire funds transfer system for domestic funds transfers,
and the funds transfer system operated by the Society for Worldwide
International Financial Telecommunication (SWIFT) for international funds
transfers.  International funds transfers may also be initiated through the
Clearing House InterBank Payment System (CHIPs) or international cable.
However, the Lender or such affiliate bank, as applicable, may use any means
and routes that the Lender or such affiliate bank, as applicable, in its sole
discretion, may consider suitable for the transmission of funds.  Each payment
order, or cancellation thereof, carried out through a funds transfer system or
a clearing house will be governed by all applicable funds transfer system rules
and clearing house rules and clearing arrangements, whether or not the Lender
or such affiliate bank, as applicable, is a member of the system, clearing
house or arrangement and each Borrower acknowledges that the Lender's or such
affiliate bank's, as applicable, right to reverse, adjust, stop payment or
delay posting of an executed payment order is subject to the laws, regulations,
rules, circulars and arrangements described herein.

         Section 12.20    Consent to Advertising and Publicity.  The Borrowers
agree that the Lender may issue and disseminate to the public information
describing the credit accommodation entered into pursuant to this Agreement,
including the name and address of the Borrowers and the amount and a general
description of the credit facilities provided hereunder.





LOAN AND SECURITY AGREEMENT - PAGE 81

         Section 12.21  Final  Agreement.  This Agreement and the other Loan
Documents are intended by the parties hereto as the final, complete and
exclusive expression of the agreement among them with respect to the subject
matter hereof and thereof.  This Agreement and the other Loan Documents
supersede any and all prior oral or written agreements between the parties
hereto relating to the subject matter hereof and thereof.

         THIS WRITTEN LOAN AGREEMENT REPRESENTS THE FINAL AGREEMENT BETWEEN THE
PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR
SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES.  THERE ARE NO UNWRITTEN ORAL
AGREEMENTS BETWEEN THE PARTIES.

         IN WITNESS WHEREOF, the parties hereto have caused this Agreement to
be executed in Dallas, Texas, by their duly authorized officers in several
counterparts all as of the day and year first written above.
