                               PROSPECTUS SUMMARY
 
     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.

(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 $0.39 and $(0.38)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.

<PAGE>   8
 
                                  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 $9.8
million and debt as a percentage of total capitalization of 28.7%. 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>   9
 
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. Based on the Company's operating experience and
consultation with its independent insurance risk advisor, 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."
 
                                        9
<PAGE>   10
 
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>   11
 
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."
 
                                       11
<PAGE>   12
 
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 $24.2 million ($28.0 million if the over-allotment
option is exercised in full), at an initial public offering price of $13.00 per
share and after deducting the estimated underwriting discount and offering
expenses payable by the Company.
 
     Approximately $14.8 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."

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."

                                    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 was $(1.27)
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 $3.1 million, the net tangible book value of
the Company at September 27, 1997 would have been approximately $4.87 per share.
This represents an immediate dilution of $8.13 per share to new investors and an
increase in the net tangible book value of approximately $6.14 per share to
existing stockholders, as illustrated by the following table:

    a company's profitability or liquidity. In addition, EBITDA may not be

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 of approximately $50,000 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.

  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.
 
                                       18
<PAGE>   19
 
     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.
 
     Due to the factors described above, the net loss for the first quarter of
fiscal 1998 was $2 million, or $(0.87) per share, compared with net income of
$263,000, or $0.12 per share, for the first quarter of fiscal 1997. Net income
and earnings per share for the first quarter of fiscal 1998 before the $2.3
million non-recurring compensation charge were $317,000 and $0.14, respectively.
 
  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. In fiscal 1996,
demand for fiberglass and resin exceeded supply, and the Company's principal
suppliers of fiberglass and resin increased prices. By fiscal 1997, additional
capacity was provided in the marketplace and prices declined. 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.
 
     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.
 
                                       19
<PAGE>   20
 
     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.
 
     Due to the factors described above, net income for fiscal 1997 was
$197,000, or $0.09 per share, compared with a net loss of $954,000 or $(0.44)
per share for fiscal 1996.
 
  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. In fiscal 1996, demand for
fiberglass and resin exceeded supply, and the Company's principal suppliers of
fiberglass and resin increased prices. By fiscal 1997, additional capacity was
provided in the marketplace and prices declined.
 
     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.
 
     Due to the factors described above, the net loss for fiscal 1996 was
$954,000, or $(0.44) per share, compared with a net loss of $103,000, or $(0.05)
per share for fiscal 1995.
 
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
 
                                       20

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.
 
     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 $13.4 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 upon satisfactory
performance through June 1998 by the Company under the Owens Corning supply
agreement. Pursuant to the supply agreement, there is no minimum volume of
fiberglass that must be purchased by the Company; however, the Company is
obligated to purchase from Owens Corning at least 90% of its fiberglass
requirements during this period. Although no assurances can be made, the Company
expects to satisfy the percentage purchase requirement. As a result, the Company
believes that it is likely that such extraordinary gain will occur in the fourth
quarter of fiscal 1998.
 
     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.
 
                                       22
<PAGE>   23
 
     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>   25
 
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>   26
 
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>   27
 
     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>   28
 
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
orders

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, based on the Company's operating experience and consultations
with its independent insurance risk advisors, it 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 Amendments), the Resource Conservation and Recovery Act ("RCRA"), and
the Occupational Safety and
 
                                       29
<PAGE>   30
 
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 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
 
                                       30
<PAGE>   31
 
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 three 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 three sites will
not have a material adverse effect on the financial condition of the Company.
With respect to the Bay Drum site, the Company has been allocated a 0.012% share
of total waste associated with the site and is negotiating to be a party to the
consent decree entered into between EPA and 94 PRPs or to participate in an
internal buy-out with other de minimis parties. The Company believes that the
cost of any de minimis settlement will not have a material adverse effect 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 effect 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 effect 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.
 
                                       31
<PAGE>   32
 
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.

DIRECTOR COMPENSATION
 
     None of the Company's directors received any compensation for their
services as a director during fiscal 1997. After completion of the Offering, the
Company intends to pay each director who is not an employee of the Company an
annual director's fee of $12,000 plus a fee of $500 for each Board or committee
meeting attended. Members of the Board of Directors who are employees of the
Company do not receive any fees. The Company reimburses all directors for
reasonable expenses incurred in connection with attending meetings of the Board.
Officers serve at the discretion of the Board of Directors and are elected
annually. There are no family relationships between the directors or executive
officers of the Company. No director is selected or serves pursuant to any
special arrangement or contract.
 
     The Board of Directors will be divided into three relatively equal classes
with up to four directors in each class, with each class serving for a term of
three years. At each annual meeting of stockholders, directors will be elected
by the holders of the Common Stock to succeed those directors whose terms are
expiring. See "Description of Capital Stock -- Common Stock."

Committee will aid management in the establishment and supervision of the
Company's financial controls, evaluate the scope of the annual audit, review
audit results, consult with management and the Company's independent auditors
prior to the presentation of financial statements to shareholders and, as
appropriate, initiate inquiries into aspects of the Company's financial affairs.

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>   36
 
     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
this Prospectus to acquire 171,030 shares of the Company's Common Stock to
certain executive officers, including options to acquire 94,742 shares granted
to Mr. de Boer, 47,371 shares granted to Mr. Orr, and 9,639 shares each granted
to Mr. Andrews, Mr. Carter and Ms. Smith. Forty percent of the options granted
to Messrs. de Boer and Orr will vest immediately and the remaining options will
vest in equal amounts on the first, second, third and fourth anniversaries of
the date of grant. The options granted to Mr. Andrews, Mr. Carter and Ms. Smith
will vest in equal amounts on each of the first four anniversaries of the date
of grant. All such options will be exercisable at a price per share equal to the
price to the public reflected on the front cover of this Prospectus and must be
exercised within five years of the date of the grant.
 
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>   37
 
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.

Chairman of the Board of Tetra, and Stephen T. Harcrow, the Company's Chairman

the brine purchases were made on a spot basis without the benefit of a contract.
 
REDEMPTION OF SERIES A PREFERRED STOCK
 
     A portion of the proceeds from this Offering will be used to redeem all of
the currently issued and outstanding Series A Preferred Stock of the Company.
Approximately 75% of the Series A Preferred Stock is currently beneficially
owned by the Company's directors or their affiliates. Upon redemption of the

                             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>   40
 
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>   41
 
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,
options to acquire 171,030 shares of
 
                                       42
<PAGE>   43
 
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
registration statements on Form S-8 to register the 367,833 shares of Common
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.
 
                                  UNDERWRITING
 
     The Underwriters named below, represented by Morgan Keegan & Company, Inc.
and Rauscher Pierce Refsnes, Inc. (the "Representatives"), have severally

indicated below opposite their respective names at the initial public offering
price less the underwriting discount set forth on the cover page of this
Prospectus.

     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
 
                                       43
<PAGE>   44
 
and to certain dealers at such price less a concession not in excess of $0.50
per share of Common Stock. The Underwriters may allow, and such dealers may
reallow, a discount not in excess of $0.10 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 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 has been
determined through negotiations among the Company and the Representatives. The
factors considered in making such determination include 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 Common Stock has been approved for listing 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
 
                                       44
<PAGE>   45
 
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 120,938
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 $13 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.

                         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.

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

           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
amount (the borrowing base) based on accounts receivable and inventories as
specified in the agreement's borrowing base formula. Borrowings under the
revolving credit facility totaled $3.0 million and $3.7 million at June 29, 1996
and June 28, 1997, respectively. The borrowing base formula yielded a maximum
borrowing base of $4.7 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,
and average availability.
 
     Ershigs' 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 amount (the borrowing base) based on accounts receivable and inventories as
specified in the agreement's borrowing base formula. Borrowings under the
revolving credit facility totaled $2 million at June 28, 1997. The borrowing
base formula yielded a maximum borrowing base of $4.9 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, and average availability.
 
     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):

     The Company paid interest on these notes of $48,000, $82,000, and $15,000
for the period December 19, 1994 (date of inception) to July 1, 1995 and during
the years ended June 29, 1996 and June 28, 1997, respectively.
 
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
covers all employees of the Containment Products Group who have satisfied
minimum employment standards. During the period December 19, 1994 (date of
inception) to July 1, 1995, and for the years ended June 29, 1996 and June 28,
1997 the Company made a gain sharing contribution equally to all eligible
employees totaling $80,000, $111,000 and $144,000, respectively based on a
distribution of 10% of quarterly earnings before taxes and gain sharing expense.
 
15. RETIREMENT PLANS
 
     During fiscal year 1995, the Company adopted a defined-contribution
retirement plan, Fluid Containment 401(k) Retirement Plan (the "Plan"), that
covers all eligible employees of the Company. Effective July 1, 1997, the Plan
was amended to include all eligible employees of Ershigs. The Plan allows
employees to defer up to 15% of their compensation, with the Company matching
50% of the first 6% of the participant's contribution. Participants are
immediately and fully vested in employer contributions. The Company's matching
contribution was $52,000, $236,000, and $277,000 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.
 
16. SEASONALITY AND INFLATION
 
     The Company's operating results are affected by the annual construction
season slowdown resulting from winter weather especially in the period December
through March. The underground fiberglass tank products

are especially impacted during the winter months. The Company believes that the
effects of seasonality will be less severe in the future, as the Company

during the periods presented in the consolidated financial statements.

18. SUBSEQUENT EVENTS
 
INITIAL PUBLIC OFFERING
 
     The Company filed a registration statement with the Securities and Exchange
Commission ("SEC") in October 1997 and two amendments 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.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     Supplemental net income per share is $0.39 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

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

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 October 1997 and two amendments 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 $(0.38) 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.

                         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.

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
period ended December 31, 1996, and for the period from October 1, 1994 to
December 31, 1994, in conformity with generally accepted accounting principles.

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.
 
4. COSTS AND ESTIMATED EARNINGS ON UNCOMPLETED CONTRACTS
 
     Costs and estimated earnings on uncompleted contracts are summarized as
follows (In thousands):

                                                                 ======
</TABLE>
 
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):

$70,000 for the year ended December 31, 1996 and for the period January 1, 1997
to February 27, 1997, respectively, related to Praxair carrying its investment

9. PROFIT SHARING PLAN
 
     The Company maintains a defined contribution profit sharing and 401(k) plan
for substantially all nonunion employees. The plan allows employees to defer up
to 15% of their compensation. Discretionary contributions to the profit sharing
plan are determined by the Board of Directors and funded annually. A profit
sharing contribution of $32,000 was made during the period from October 1, 1994
to December 31, 1994. No profit sharing contribution was made for the years
ended December 31, 1995 and 1996, or the period from January 1, 1997 to February
27, 1997.

                                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.

                        GL&V/LAVALLEY CONSTRUCTION, INC.
 
                  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.

                         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

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
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.

     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.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
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.

                   NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
                               SEPTEMBER 30, 1997
 
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.
