                               PROSPECTUS SUMMARY
 
     The following summary is qualified in its entirety by the more detailed
information and the consolidated financial statements and notes thereto
appearing elsewhere, or incorporated by reference, in this Prospectus. Unless
otherwise indicated, or the context otherwise requires, all information in this
Prospectus (i) is based on the assumption that the Underwriters' over-allotment
option is not exercised and (ii) gives effect to the three-for-two split of the
Common Stock in June 1997 (the "Stock Split").
 
                                  THE COMPANY
 
GENERAL
 
     The Company is a leader in the design, engineering and manufacture of
cryogenic (low-temperature) systems and equipment. The majority of the Company's
products, including its brazed aluminum heat exchangers (hereinafter referred to
as heat exchangers), cold boxes, cryogenic tanks and cryogenic components are
used in the processing, liquefaction, storage and transportation of industrial
gases and hydrocarbons. The Company also supplies products for other special
applications, including high vacuum systems and specialty stainless steel
tubing.
 
     The Company's products are sold primarily to the industrial gas and
hydrocarbon processing markets. Customers in these markets use the Company's
heat exchangers and cold boxes to produce industrial gases, such as liquefied
nitrogen, oxygen and argon, and to purify, separate and liquefy hydrocarbons
such as natural gas and ethylene. The Company's cryogenic tanks are used by
these same customers to store and transport gases in liquefied form. Cryogenic
components, including cryogenic pumps and vacuum jacketed piping systems, allow
liquefied gas to be carried from tank to plant for use in industrial
applications. Cryogenic components also are purchased by liquefied gas producers
for use in cold box assemblies.
 
     The Company's sales for the year ended December 31, 1996 reached $148.4
million, an increase of 31.9% over sales of $112.5 million in 1995. The
Company's operating income in 1996 improved to $23.3 million from $12.7 million
in 1995, an increase of 83.6%. In July 1997, the Company acquired Cryenco
Sciences, Inc. ("Cryenco"); including Cryenco's results on a pro forma basis,
the Company's sales and operating income for 1996 were $179.0 million and $25.1
million, respectively. See "-- Recent Acquisition." Management believes that
global expansion of the industrial gas and hydrocarbon processing markets
presents attractive opportunities for growth. Management anticipates demand for
the Company's products in the industrial gas markets to increase over the next
several years, driven principally by global industrialization, heightened
environmental standards and demands for increased purity of gas products and
increased efficiency in gas production. In the hydrocarbon processing market,
management expects continued strong domestic and international growth, stemming
in part from increased global demand for liquefied natural gas ("LNG") and
ethylene. As a result of these favorable trends, management anticipates that the
Company's combined equipment sales to the industrial gas and hydrocarbon
processing markets will increase from approximately 70% of sales in 1996 to as
much as 85% in 1998.
 
BUSINESS STRATEGY
 
     The Company intends to strengthen its position as a leading provider of
cryogenic products by pursuing the following key strategies:
 
     Focus on High-Margin, Niche Products.  The Company has developed a
particular expertise in the design, engineering and manufacture of cryogenic
systems and equipment. The Company will continue to focus on markets requiring
such specialized engineering and technical capability, rather than on
broader-based markets in which competition is largely based on price. The
Company believes that, by focusing on the market niche for cryogenic
applications, it has fewer competitors
 
                                        3
<PAGE>   5
 
and higher margins for its products than producers in markets that use
standardized or high-volume products. The Company's gross margin in the first
six months of 1997 was 30.5%.
 
     Leveraging Customer Relationships.  The Company has built and sustained
long-term relationships with many of its major customers. Most of the Company's
largest customers have been customers for the last 10 years or more, and a
substantial quantity of the Company's annual sales are made to these same major
customers. As the Company's customers grow domestically and internationally,
they take the Company's products into new growth markets.
 
     Expanding International Direct Sales.  Although the Company is a leading
North American producer of cryogenic systems and equipment, the Company's direct
sales outside of North America are relatively modest. In 1996, the Company's
international sales constituted approximately 25% of its total sales, but were
mostly sales to North American customers that incorporated the Company's
products into their own export products. The Company believes that demand for
its products is growing internationally at a faster rate than in North America.
The Company intends to expand its independent sales representative network
outside North America in order to strengthen its market share in selected
markets in South America, the Pacific Rim and the Middle East.
 
     Continued Emphasis on Operating Efficiencies.  The Company has devoted
considerable efforts to maximizing its production efficiency. Management
believes that such efforts have resulted in higher marginal returns due to
substantial improvements in throughput, utilization of existing capacity and
organizational efficiency. The Company intends to continue efforts to find new
ways to improve operating efficiency.
 
     Pursuing Strategic Acquisitions.  A key component of the Company's growth
strategy is the acquisition of complementary businesses that can effectively
increase the Company's market share and operating efficiencies, while
simultaneously expanding the Company's customer base and presence in geographic
regions which it does not currently serve, including in selected markets abroad.
The Company continually reviews acquisition opportunities, and management
believes that complementary domestic and international acquisition opportunities
exist. Management further believes that the high level of ability and experience
of its senior managers in identifying and completing acquisitions and in
managing the operations of acquired companies, as well as the Company's low debt
levels following the Offering and low working capital requirements, position the
Company favorably to execute this strategy.
 
RECENT ACQUISITION
 
     On July 31, 1997, the Company acquired all of the outstanding shares of
Cryenco, a Denver, Colorado based manufacturer of cryogenic tanks and related
products for the transportation, storage and dispensing of LNG and liquefied
argon, oxygen and nitrogen. Consideration for the acquisition included the
payment of $19.7 million to purchase the outstanding common stock and certain
warrants of Cryenco, the payment of $685,000 to redeem its outstanding preferred
stock, and the assumption of approximately $6.2 million in indebtedness for
borrowed money. The Company also assumed Cryenco's obligations under other
warrants, which were converted into warrants to purchase Common Stock of the
Company, and are recorded in the Company's accounts at an estimated fair value
of $436,000.
 
                                     * * *
 
     The Company was organized in June 1992 as a Delaware corporation. Unless

                                  RISK FACTORS
 
     This Prospectus and certain of the documents incorporated herein by
reference contain forward-looking statements that involve risks and
uncertainties. Statements in this Prospectus regarding future financial
performance and other statements containing the words "expect," "believe,"
"anticipate," "project," "estimate," "predict," "intend" and similar expressions
are forward-looking statements. The Company's actual results could differ
materially from those anticipated in such forward-looking statements as a result
of a variety of factors, including those set forth in the following risk factors
and elsewhere in this Prospectus. Prospective investors should consider
carefully the following factors, in addition to other information contained in
this Prospectus, prior to making an investment in the Common Stock.
 
CYCLICALITY OF DEMAND FOR COMPANY PRODUCTS
 
     Demand for the Company's products depends in part upon the level of capital
and maintenance expenditures by its industrial customers, in particular those by
industrial gas and hydrocarbon processing concerns. These industries
historically have been cyclical in nature and vulnerable to general downturns in
the economy. Decreases in industry spending could have a material adverse effect
upon the demand for the Company's products and the Company's business, financial
condition and results of operations.
 
CUSTOMER CONCENTRATION; GOVERNMENT CONTRACTS
 
     A small number of customers has accounted for a substantial portion of the
Company's historical net sales, and the Company expects that a limited number of
customers will continue to represent a substantial portion of the Company's net
sales for the foreseeable future. Approximately, 30%, 17% and 18% of the
Company's sales for the years ended December 31, 1996, 1995 and 1994,
respectively, were made to Air Liquide, Air Products, BOC and Praxair, which
management believes are the four largest producers in the industrial gas market.
The Company also sells products to the United States government as a contractor
and a subcontractor. Most of the Company's government-related sales are to prime
contractors for NASA, the United States Department of Energy and the United
States Department of Defense. In the years ended December 31, 1996, 1995 and
1994, government contracts and subcontracts accounted for approximately 11%, 5%
and 3%, respectively, of the Company's sales. The loss of any of the Company's
major customers or a decrease in orders by such customers could have a material
adverse effect on its business, financial condition and results of operations.
 
AVAILABILITY OF SUITABLE ACQUISITIONS; INTEGRATION OF OPERATIONS
 
     A key component of the Company's growth strategy is the acquisition of
businesses that complement its existing products and services. The Company's
acquisition strategy involves the potential risks inherent in assessing the
value, strengths, weaknesses, contingent or other liabilities and potential
profitability of acquisition candidates and in integrating the operations of
acquired companies. In addition, any acquisition of a foreign business may
increase the Company's exposure to certain risks inherent in doing business
outside the United States, including currency exchange rate fluctuations,
restrictions on the repatriation of profits, compliance with foreign laws and
standards and political risks. There can be no assurance that acquisition
opportunities will continue to be available, that the Company will have access
to the capital required to finance potential acquisitions, that the Company will
continue to acquire businesses or that any business acquired will be integrated
successfully or prove profitable.
 
COMPETITION
 
     Although many of the Company's products serve niche markets, a number of
the Company's direct and indirect competitors in these markets are major
corporations, some with substantially greater technical, financial and marketing
resources than those of the Company, and there can be
 
                                        7
<PAGE>   9
 
no assurance that other competitors will not enter these markets. In the event
of an industry downturn, customers who typically outsource their need for
cryogenic systems to the Company may use their excess capacity to fabricate such
systems themselves. The Company also competes in the sale of a limited number of
products with certain of its major customers. Because such competition is
limited in its scope, management believes that such competition currently does
not have an adverse effect on its relationships with these customers.
 
FIXED-PRICE CONTRACT EXPOSURE
 
     A substantial portion of the Company's revenues is derived from fixed-price
contracts for large system projects. To the extent that original cost estimates
prove to be inaccurate, profitability from a particular contract may be
adversely affected, which, in turn, could have a material adverse effect on the
Company's business, financial condition and results of operations.
 
COLLECTIVE BARGAINING AGREEMENTS
 
     Of the Company's approximately 1,250 employees, 267 employees of its ALTEC
International Limited Partnership ("ALTEC") subsidiary are covered by a
collective bargaining agreement expiring February 7, 1998, and 93 employees of
its Process Engineering ("PEI") subsidiary are covered by a collective
bargaining agreement expiring August 27, 1999. Although the Company believes its
relations with its union employees are good, there can be no assurance that
ALTEC and PEI will be successful in negotiating new agreements with the unions
representing their employees on terms favorable to the Company or can do so
without experiencing work stoppages by some of their employees. Because of
ALTEC's importance to the profitability of the Company, a work stoppage at ALTEC
could have a material adverse effect on the Company's business, financial
condition and results of operations.
 
EXPOSURE TO LIABILITY
 
     Due to the high pressures and low temperatures at which many of the
Company's products are used, the Company could be at risk if an accident is
caused by a defective product manufactured by the Company. Management believes
that the Company meets existing professional specification standards recognized
or required in the industries in which it operates, and has had no material
product liability claims brought against it. Although the Company currently
maintains product liability coverage which it believes is adequate for the
continued operation of its business, such insurance may prove inadequate or
become difficult to obtain or unobtainable in the future on terms acceptable to
the Company.
 
VARIABILITY OF OPERATING RESULTS
 
     The Company's operating results historically have fluctuated from quarter
to quarter as a result of a number of factors, including the value, timing and
shipment of individual orders and the mix of products sold. Moreover, although
the Company generally recognizes product revenues upon shipment of its products,
certain large system contracts are recognized using the percentage of completion
method of accounting. Accordingly, revenue in any quarter is dependent in part
on progress towards completion of large system contracts by the Company.
 
DEPENDENCE ON KEY PERSONNEL
 
     The success of the Company's business will continue to depend substantially
upon the efforts, abilities and services of its executive officers and certain
other key employees. The loss of one or more key employees, particularly Arthur
S. Holmes, Chairman and Chief Executive Officer, and James R. Sadowski,
President and Chief Operating Officer, could adversely affect the Company's
operations. The Company's ability to attract and retain qualified engineers and
other professionals,
 
                                        8
<PAGE>   10
 
either through direct hiring or acquisition of other businesses employing such
professionals, will also be an important factor in determining the Company's
future success.
 
ENVIRONMENTAL MATTERS
 
     The Company's operations are subject to federal, state, local and foreign
laws and regulations relating to the protection of the environment. Sanctions
for noncompliance may include revocation of permits, corrective action orders,
administrative or civil penalties and criminal prosecution. The Company's
business involves environmental management and issues typically associated with
historical manufacturing operations, and the Company is developing work plans
for remediation of environmental conditions involving certain of its facilities.
To date, the Company's cost of complying with environmental 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. See "Business -- Environmental Matters."
 
INTELLECTUAL PROPERTY MATTERS
 
     The Company relies on a combination of internal procedures, nondisclosure
agreements, patents, trademarks, and copyright law to protect its intellectual
property. There can be no assurance that the Company's intellectual property
rights can be successfully asserted in the future or will not be invalidated,
circumvented or challenged. In addition, the laws of certain foreign countries
in which the Company's products may be sold do not protect the Company's
intellectual property rights to the same extent as the laws of the United
States. The failure or inability of the Company to protect its proprietary
information could have a material adverse effect on the Company's business,
financial condition and results of operations.
 
                              RECENT DEVELOPMENTS
 
     On July 31, 1997, the Company acquired all of the outstanding shares of
Cryenco, a Denver, Colorado based manufacturer of cryogenic tanks and related
products for the transportation, storage and dispensing of LNG and liquefied
argon, oxygen and nitrogen. Consideration for the acquisition included the
payment of $19.7 million to purchase the outstanding common stock and certain
warrants of Cryenco, the payment of $685,000 to redeem its outstanding preferred
stock, and the assumption of approximately $6.2 million in indebtedness for
borrowed money. The Company also assumed Cryenco's obligations under other
warrants, which were converted into warrants to purchase Common Stock of the
Company, and are recorded in the Company's accounts at an estimated fair value
of $436,000. The Company financed the cash portion of its acquisition of Cryenco
with borrowings under a $45 million credit facility between the Company and
National City Bank and NBD Bank entered into in July 1997 (the "New Credit
Facility"). See "Pro Forma Financial Data." Management believes that the
addition of Cryenco's line of products, including cryogenic transport trailers,
cryogenic intermodal containers, MRI cryostats and other cryogenic components,
complements the Company's existing line of cryogenic tanks and cryogenic
components and offers significant growth opportunities through cross-selling to
existing customers and new product development.

                                USE OF PROCEEDS
 
     The net proceeds from the sale of the 1,300,000 shares of Common Stock
offered by the Company hereby (at an assumed public offering price of $21.125
per share and after deducting the underwriting discount and estimated offering
expenses payable by the Company) are estimated to be approximately $25.5 million
($33.8 million if the Underwriters' over-allotment option is exercised in full).
The Company intends to use net proceeds from the sale of the shares offered by
it hereby to repay amounts outstanding under the New Credit Facility. At August
31, 1997, the Company had an aggregate of $24.0 million in borrowings
outstanding under the New Credit Facility which currently bears interest at a
rate approximately equal to the prime rate (currently 8.5%) and has a maturity
date of May 31, 2000. The indebtedness incurred under the New Credit Facility
was used to finance working capital needs, capital expenditures and the
acquisition of Cryenco. The Company intends to use the balance, if any, of the
net proceeds for general corporate purposes, including working capital and
capital expenditures. A portion of such balance may also be used, together with
borrowings under the New Credit Facility or other sources of financing, to
acquire or invest in complementary businesses. The Company has no current plans,
agreements or commitments with respect to any such acquisition or investment,
and the Company is not currently engaged in any negotiations with respect to any
such transaction. Pending such uses, the net proceeds will be invested in
investment grade, short-term, interest-bearing securities.
 
     The Company will not receive any of the proceeds from the sale of the
shares by the Selling Stockholders.

(1) To be paid on September 15, 1997.
 
     On September 9, 1997, the last sale price of the Common Stock as reported
on the New York Stock Exchange Composite Tape was $21.125 per share. As of
August 31, 1997, there were 931 holders of record of the Common Stock. The
Company estimates that approximately 3,100 additional stockholders own stock
held for their accounts at brokerage firms and financial institutions.
 
     Cash dividends are payable quarterly, upon authorization by the Board of
Directors. Regular payment dates are March 15, June 15, September 15 and
December 15. The payment of cash dividends by the Company has been and will
continue to be at the discretion of the Board of Directors and will depend upon,
among other factors, the capital requirements, operating results, financial
condition and restrictions imposed by financing arrangements of the Company from
time to time. The New Credit Facility allows the Company to pay cash dividends
not to exceed $4 million annually, subject to compliance with other loan
covenants. The Company is currently seeking an amendment to the New Credit
Facility to allow the Company to pay cash dividends not to exceed $6 million
annually.

                            PRO FORMA FINANCIAL DATA
 
     The following unaudited pro forma condensed consolidated financial
statements are based on the historical consolidated financial statements of the
Company, adjusted to give effect to the acquisition of Cryenco and the
application of net proceeds of the Offering to repay indebtedness (the
"Transactions"). The unaudited pro forma condensed consolidated balance sheet
gives effect to the Transactions as if such had occurred on June 30, 1997. The
unaudited pro forma condensed consolidated statements of operations give effect
to the Transactions as if such had occurred on January 1, 1996. The unaudited
pro forma condensed consolidated financial statements are presented for
illustrative purposes only and are not necessarily indicative of the financial
position or results of operations that would have actually been reported had the
Transactions occurred on January 1, 1996, nor are they necessarily indicative of
future financial position or results of operations. The pro forma adjustments
reflected herein are based on preliminary estimates and assumptions and are
subject to revision as more information becomes available. In management's
opinion, the final adjustments are not expected to be materially different from
the preliminary adjustments. The unaudited pro forma condensed consolidated
financial statements should be read in conjunction with the Company's historical
consolidated financial statements and the related notes thereto and
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" included elsewhere herein.

(1) The Pro Forma Condensed Consolidated Statements of Operations for the
    six-month period ended June 30, 1997 and the year ended December 31, 1996
    give effect to the acquisition of Cryenco as if it occurred on January 1,
    1996 by combining the indicated periods of the Company with the six-month
    period ended May 31, 1997 and the twelve-month period ended November 30,
    1996 for Cryenco to conform the different fiscal year ends.
 
(2) To record reduction in interest expense and the related tax effect for the
    six months ended June 30, 1997 and the year ended December 31, 1996, which
    would have been realized had the Offering occurred January 1, 1996.
 
(3) Represents the incremental amortization due to the application of purchase
    accounting resulting from an increase of $8,863,000 in the basis of net
    assets acquired amortized over a 40 year period.
 
(4) Reflects additional interest expense which would have been incurred by the
    Company assuming the acquisition of Cryenco had occurred January 1, 1996.
    Interest expense has been calculated based on the $20.2 million utilization
    on the available line of credit used to fund the cash portion of the
    consideration in conjunction with the acquisition of Cryenco.
 
(5) Reflects the income tax effect assuming the acquisition of Cryenco had
    occurred on January 1, 1996. The goodwill amortization created by this

          MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                           AND RESULTS OF OPERATIONS
 
RESULTS OF OPERATIONS
 
  Overview
 
     The Company recorded its second consecutive year of record sales, earnings
and order backlog in 1996, driven by continued strong demand for its products in
both the industrial gas and hydrocarbon processing markets, together with the
benefits of the Laser Interferometer Gravitational-Wave Observatory ("LIGO")
contract reported within its special products business. These record levels of
operating results have continued in the first half of 1997.
 
     The Company normally recognizes revenues from sales of its products at
completion, which is generally at the time of shipment. As revenues generated
from a small number of products can constitute a significant portion of the
Company's overall revenues, the timing of completion of such products and the
resulting recognition of revenue therefrom could cause the Company's results of
operations to vary from quarter to quarter.
 
     For multi-year contracts, the Company recognizes revenue under the
percentage of completion method of accounting, whereby revenue and profit are
recognized throughout the performance period of the contract. As a result, the
Company must estimate the revenues to be generated from such contracts and the
cost associated with completing those contracts, and apply such estimates
throughout the length of the contracts. The Company evaluates the progress of
all such contracts each month. Consequently, the Company's estimates may require
adjustment from time to time. The cumulative impact of revisions in total cost
estimates during the progress of work is reflected in the period in which these
changes become known. Those adjustments may cause the Company's results of
operations to fluctuate from quarter to quarter.
 
     Historically, the Company has attempted to respond to changing market
conditions by using performance-related compensation and by adjusting fixed
costs and capital expenditures. Due to a significant reduction in new equipment
purchases in both the industrial gas and hydrocarbon processing markets during
1992 and early 1993, the Company experienced a reduced level of sales in 1993
and 1994. Actions taken by the Company to reduce its fixed costs during this
period were generally slower to take effect than the reduction in sales, causing
a decline in operating margin. In addition, during this period the Company
restructured its cryogenic tank manufacturing business to reduce its cost
structure, resulting in a restructuring charge being recorded in 1994. The
Company also shifted its emphasis to higher margin products and changed its
compensation program in order to improve the profitability of its other
businesses.
 
     The following table sets forth, for the periods indicated, the percentage
relationship to sales of the Company each line item represents.

(1) Gross profit by market does not reflect $950,000 of reserves recorded in the
    third quarter of 1994 related to various product warranty claims and
    estimated contract losses.
 
  Six Months Ended June 30, 1997 and June 30, 1996
 
     Sales for the six months ended June 30, 1997 were $84.2 million versus
$65.3 million for the comparable 1996 period, an increase of $18.9 million or
28.9%. The growth in sales was primarily the result of the continued strength in
heat exchanger sales for both the industrial gas and hydrocarbon processing
equipment markets. Also showing strong sales for the period compared to the same
period in the prior year were nitrogen rejection unit cold boxes related to
hydrocarbon processing and high-vacuum equipment related to the LIGO project.
The LIGO project is a three-year, $39 million project which commenced in 1995
and which is accounted for under the percentage of completion method of
accounting.
 
     Gross profit for the six months ended June 30, 1997 was $25.6 million
versus $19.8 million for the comparable 1996 period, an increase of $5.8 million
or 29.5%. Strong market conditions, particularly in the industrial gas equipment
market and increasingly in the hydrocarbon processing equipment market,
continued to support favorable pricing and higher throughput. Gross profit
margin for the six-month period that ended June 30, 1997 was 30.5% and is
consistent with the 30.3% performance for the first six months of 1996. Products
supporting this gross margin performance included heat exchangers, cold box
design and fabrication, and certain high vacuum products including LIGO vessels
and cryopumps.
 
     Selling, general and administrative ("SG&A") expense for the six-month
period ended June 30, 1997 was $11.7 million, approximately $2.4 million higher
than for the same period in 1996. The increase in SG&A expense in 1997 was
largely driven by the variable expenses of profit sharing,
 
                                       18
<PAGE>   20
 
management incentive compensation and selling commissions, all of which are
closely tied to increasing profitability and sales levels. SG&A expense for 1997
includes the costs for outside consultants that are working with the Company to
increase throughput in various facilities. Higher SG&A expense was also due in
part to certain non-recurring charges occurring during the six-month period
ended June 30, 1997.
 
     Net interest expense for the six-month period ended June 30, 1997 was
$18,000 versus $418,000 for the same period in 1996. The Company significantly
reduced its average level of borrowing in the first half of 1997 compared to
1996.
 
     Cryenco Acquisition.  Including six months of Cryenco operating results on
a pro forma basis increases sales by $13.9 million for the six-month period
ending June 30, 1997, consisting mainly of industrial gas equipment such as
industrial gas trailers, TVAC(TM) intermodal containers and MRI cryostats and
components not previously supplied by the Company.
 
     The pro forma gross profit margin is 28.6%, which is nearly 2% below the
actual figure reported by the Company. Although the Company believes that
Cryenco products have had a lower composite gross profit margin than the
Company's products, Cryenco's gross profit margin during the last six months had
been additionally affected by the revisions related to Cryenco's application of
percentage of completion accounting.
 
     Pro forma SG&A expense includes the anticipated effect of amortization of
the goodwill from the transaction, which will be approximately $222,000 per
year. Also included in the six-month results are costs related to several
product development projects that will be combined with other current Company
projects, such as LNG dispensing, and several research and development projects
for which the Company will pursue funding from outside sources.
 
     Interest expense on a pro forma basis increases substantially for the
acquisition of Cryenco. Based on the debt resulting from the payment of the
purchase price and the debt assumed in the transaction, the Company would have
had $1.3 million of interest expense in the first six months of 1997. The
Company anticipates the elimination of most of this additional interest expense
through the application of net proceeds from the Offering.
 
     The Company will experience a slightly higher effective tax rate with the
acquisition of Cryenco as the goodwill created in the transaction is not tax
deductible.
 
  Years Ended December 31, 1996 and 1995
 
     Sales for 1996 were $148.4 million, an increase of $35.9 million or 31.9%
over 1995. The largest increase in sales over 1995 came in industrial gas
equipment totaling $23.9 million, consisting of increases of $10.1 million in
cryogenic tanks, $8.5 million in heat exchangers, $2.9 million in cold boxes and
$2.4 million in assorted cryogenic components during 1996. Sales in the
hydrocarbon processing equipment area increased $6.5 million, a majority of
which was in heat exchangers, which were for the most part supplying an increase
in the demand for ethylene-related equipment. Sales to the specialty products
market also increased in 1996. Much of the sales improvement in this market was
the result of vacuum equipment being supplied to the LIGO project, which totaled
approximately $13.0 million during 1996.
 
     Gross profit for 1996 increased $14.2 million or 46.2% from 1995 levels.
The gross profit margin increased from 27.4% in 1995 to 30.3% in 1996. As in
sales, a large portion of the improvement in both gross profit and in gross
profit margin came from the industrial gas sector. The most significant
improvement was in the cryogenic tank business, which was restructured in 1994.
This business moved from a negative gross profit margin to a gross profit margin
level consistent with the Company's other industrial gas products. The heat
exchanger market also saw large volume and price improvement in 1996.
 
                                       19
<PAGE>   21
 
     As the LIGO project progresses toward completion, it is having a positive
effect in the specialty products area, where the gross profit margin has grown
to 28.4% in 1996 from 27.5% for 1995.
 
     SG&A expense totaled $21.7 million for 1996, an increase of $3.6 million
from 1995. As a percentage of sales, SG&A expense decreased from 16.1% in 1995
to 14.7% in 1996. This improvement is the result of increasing volume relative
to the fixed overhead costs. The $3.6 million increase in expense was in support
of increased sales.
 
     Net interest expense declined during 1996 with borrowings declining from
$14.6 million to a net positive cash position. This was also the last year of
amortization for the loan origination costs related to a $25 million credit
agreement.
 
     The 1996 tax expense includes the positive effect of eliminating the
deferred tax valuation allowance that related to certain tax loss carry forwards
as well as the ongoing benefits of several different tax credits.
 
  Years Ended December 31, 1995 and 1994
 
     Sales for 1995 were $112.5 million versus $84.3 million for 1994, an
increase of $28.2 million, or 33.5%. Sales grew across all markets and received
an additional boost from the acquisition of CVI, now a subsidiary of the
Company, in the fourth quarter of 1994. The continued strong demand for heat
exchangers, cryogenic storage tanks and stainless steel tubing was partially
offset by a weak market and higher than estimated expenses for certain contracts
in the high vacuum area.
 
     Strong industrial gas market conditions, extensive productivity
improvements in the cryogenic tank business, demand for redraw stainless steel
tubing, and strong throughput at each of the Company's plants resulted in gross
profit for 1995 of $30.8 million versus $15.8 million for 1994, an improvement
of $15.0 million, or 94.7%. This result reflects an improved gross profit margin
to 27.4% from 18.8% in 1994. The products supporting this improved gross profit
margin performance were stainless steel tubing, heat exchangers and cryogenic
storage tanks. This improved performance more than compensated for the
anticipated low-margin sales in several long-term high vacuum projects and the
start-up costs of the Company's cold box fabrication facility in New Iberia,
Louisiana.
 
     SG&A expense for 1995 was $18.1 million, approximately $3.1 million higher
than for 1994. As a percentage of sales, SG&A expense was 16.1% in 1995 versus
17.8% in 1994. The addition of CVI increased SG&A expense by $2.3 million over
the prior year. The remaining increases were driven by higher commissions and
employee profit sharing.
 
     Net interest expense for 1995 was $1.9 million versus $1.0 million in 1994.
Increased interest charges in 1995 reflect higher borrowing levels to meet
increased working capital requirements of the Company's operating units and the
acquisition indebtedness related to CVI. As of October 1, 1995, the interest
rate spread on the Company's borrowings was reduced by 25 basis points to LIBOR
plus 200 basis points.
 
     The 1995 effective tax rate of 34.7% reflects the positive effect of
certain tax credits taken in the most recently filed income tax returns and the
anticipated effect of such credits on the Company's 1995 tax returns.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     Cash provided by operations in the first six months of 1997 was $4.1
million compared to $19.8 million in the first six months of 1996. Cash provided
by operations in 1996 was $32.9 million compared to $8.8 million in 1995 and
$6.8 million in 1994. The Company's 1996 cash flow represented earnings and
significant cash flow from customer advances and milestone billings on many jobs
in backlog, especially the LIGO project. During the first six months of 1997,
much of the work progressed against the aforementioned milestone billings, thus
incurring costs without new
 
                                       20
<PAGE>   22
 
inflows of cash. This trend is expected to continue into the third quarter of
1997, when the Company will reach several major milestones on the LIGO project.
As the Company takes on large orders and progresses through completion, there
are normally wide swings in working capital requirements depending on negotiated
terms. Due to strong progress billings to the Company's customers and strong
operating cash flow, the Company is currently well positioned in regard to
working capital despite the large backlog and related inventory needs.
 
     Capital expenditures for the first six months of 1997 were $4.2 million
compared with $1.6 million for the same period in 1996. The level of capital
expenditures in 1997 is related to the expansion of capacity at the ALTEC
facility. These expenditures have been and will continue to be financed, for the
most part, by an industrial revenue bond. Capital expenditures in 1996, 1995,
and 1994 were $4.9 million (excluding $3.6 million for the acquisition of land
and building at the Company's Westborough, Massachusetts facility), $2.1 million
and $1.3 million, respectively. The 1996 capital expenditures relate to the
expansion of capacity at its heat exchanger and cold box manufacturing
facilities, as well as general throughput improvements at the other locations.
The 1995 expenditures included the leasehold improvements and various machinery
and equipment purchases for the Company's initial operation at the Company's
cold box fabrication facility in New Iberia, Louisiana, along with various
productivity-enhancing machinery and equipment throughout all of the Company's
facilities.
 
     During the first half of 1997, the Company acquired 371,550 shares
(adjusted for the Stock Split) under its share repurchase program at a total
cost of approximately $5.5 million.
 
     The Company anticipates sufficient cash flow from operations and available
borrowings to fund interest payments, dividends, planned capital expenditures
and future acquisitions. As of June 30, 1997, the Company's borrowings on its
$25 million credit facility totaled $2.5 million. In July 1997, the Company
entered into the $45 million New Credit Facility to enable it to complete the
acquisition of Cryenco. At August 31, 1997, the Company had an aggregate of
$24.0 million outstanding under the New Credit Facility. The Company intends to
apply net proceeds from the Offering to repay its borrowings under the New
Credit Facility.

                                    BUSINESS
GENERAL
 
     The Company is a leading supplier of standard and custom-built industrial
process equipment, primarily for cryogenic (low-temperature) applications. The
Company has developed a particular expertise in cryogenic systems and equipment,
which operate at low temperatures sometimes approaching absolute zero (0 degrees
Kelvin/-273 degrees Centigrade/-459 degrees Fahrenheit). The majority of the
Company's products, including heat exchangers, cold boxes, cryogenic tanks and
other cryogenic components, are used in the processing, liquefaction, storage
and transportation of gases and hydrocarbons. The Company also supplies products
for special applications, including high vacuum systems and specialty stainless
steel tubing.
 
MARKET OVERVIEW
 
     The markets served by the Company's principal products are the industrial
gas market and hydrocarbon processing market. All categories of the Company's
cryogenic products, including heat exchangers, cold boxes, cryogenic tanks and
cryogenic components, serve both of these markets. In 1996, the industrial gas
and hydrocarbon processing markets together accounted for approximately 70% of
the Company's sales. By 1998, sales to these markets are expected to constitute
as much as 85% of the Company's sales.
 
     Management believes that the global expansion of the industrial gas and
hydrocarbon processing markets presents attractive opportunities for growth. To
date, the sources of the Company's international business principally have been
its large domestic-based customers who are aggressively expanding into
international markets, and large foreign-based companies with significant U.S.
operations. In 1996, approximately 25% of the Company's sales were for job sites
outside the United States. To position the Company to take advantage of
anticipated growth opportunities in the industrial gas and hydrocarbon
processing markets abroad, management recently has concentrated its efforts on
enhancing the Company's international presence. Management intends to increase
the amount of the Company's existing sales to large multinational gas producers
and to strengthen international direct sales by bolstering its network of
independent sales representatives in foreign markets.
 
     The industrial gas market is the largest market served by the Company,
representing approximately 50% of its sales in 1996. The top world producers of
industrial gases have been among the Company's largest customers for each of the
last three years. Producers of industrial gases separate atmospheric air into
its component gases using cryogenic processes. The resultant liquid gases are
then stored and transported for ultimate use by a wide variety of customers in
the petrochemical, electronics, glass, paper, metals, food, fertilizer, welding,
enhanced oil recovery and medical industries. Industrial gas producers use heat
exchangers and cold boxes to produce liquid gases, and cryogenic tanks and
cryogenic components, including pumps, valves and piping, to store, transport
and distribute liquid gases to end users. Management anticipates demand for the
Company's products in the industrial gas markets will increase over the next
several years, driven principally by global industrialization, heightened
environmental standards and demands for increased purity of gas products and
increased efficiency in gas production. A recent industrial gas industry report
projects a 6% annual growth rate in worldwide demand for industrial gases
through the year 2000. Management believes that demand for cryogenic equipment
will grow as global demand for industrial gases increases.
 
     Representing approximately 20% of the Company's sales in 1996, the
hydrocarbon processing market consists of petrochemical and natural gas
processors. Natural gas processing involves the separation and purification of
natural gas for the production of liquid gas end products such as methane (when
liquefied, LNG), ethane, propane and butane, and by-products such as helium,
which have numerous commercial and industrial applications. In the petrochemical
industry, cryogenic separation and purification processes are required to
produce ethylene (the basic
 
                                       22
<PAGE>   24
 
building block of plastics), propylene and numerous other primary hydrocarbons
having industrial uses. Like the industrial gas market, the hydrocarbon
processing market uses all of the categories of the Company's cryogenic products
in the gas separation and purification processes and the subsequent storage and
distribution of liquid gases. Major customers for the Company's products in the
hydrocarbon processing markets are large multinational firms in the oil and gas
industry, and large engineering and construction concerns. Management
anticipates continued strong domestic and international growth in the
hydrocarbon processing market. This market growth is expected to stem in part
from increased global demand for LNG, which, according to one industry report,
is the fastest growing segment of the world energy market with a projected 7%
annual growth rate over the next several years. Demand for ethylene is
forecasted by an industry journal to grow at an annual rate of 5% for the rest
of the decade.
 
     In addition to the industrial gas and hydrocarbon processing markets, the
Company also serves certain special market niches, the two largest of which are
vacuum systems and specialty stainless steel tubing. Vacuum equipment is
supplied principally to the satellite testing market, which has become
increasingly active as a number of new satellite communications systems are
developed worldwide. Vacuum equipment also is supplied to observatories for
telescope mirror coating. Under the Company's largest single contract to date,
the Company supplies sophisticated vacuum equipment to the LIGO project, a
government funded gravitational observatory research project. The Company
anticipates continued growth in its share of the market for large sophisticated
vacuum systems. The Company's specialty stainless steel tubing is supplied
principally to distributors who in turn sell to customers having immediate or
short lead time needs. As the Company's stainless steel tubing is intended to
meet short delivery schedules, it commands high margins in this spot-market
business.
 
PRODUCTS
 
     The Company's principal products include the following:
 
     Heat Exchangers.  The Company is the leading designer and manufacturer of
cryogenic heat exchangers. Using technology pioneered by the Company, heat
exchangers are incorporated into systems such as cold boxes to facilitate the
progressive cooling and liquefaction of air or hydrocarbon mixtures for the
subsequent recovery or purification of component gases. In the industrial gas
market, heat exchangers are used to obtain high purity atmospheric gases, such
as oxygen, nitrogen, and argon, which have numerous diverse industrial
applications. In hydrocarbon processing industries, heat exchangers allow
producers to obtain both purified forms of hydrocarbons and a variety of gas
by-products, such as methane, ethane, propane and ethylene, which are
commercially marketable for various industrial or residential uses. Heat
exchangers are customized to the customer's order and range in price from
$30,000 for a relatively simple unit to as high as $10 million for a major
project.
 
     Management anticipates continued strong demand for its heat exchangers,
resulting substantially from increased activity in the petrochemical and liquid
natural gas segments of the hydrocarbon processing market. In particular,
management believes that continuing efforts by less developed countries to
broaden their industrial base present a promising source of demand for the
Company's heat exchangers. Demand for heat exchangers in developed countries is
expected to continue as firms upgrade their facilities for greater efficiency
and regulatory compliance. To ensure adequate capacity for anticipated growth in
demand in heat exchangers, a major expansion of the Company's facilities was
recently completed.
 
     The Company's principal competitors for heat exchangers are Linde,
Sumitomo, IMI, Kobe and Nordon. Management believes that the Company is the only
producer of large brazed aluminum heat exchangers in the United States, and has
the leading market share in the global market for heat exchangers. Major
customers for the Company's heat exchangers in the industrial gas market
 
                                       23
<PAGE>   25
 
include Air Liquide, Air Products, BOC, MG Industries and Praxair, and in the
hydrocarbon processing market producers including AMOCO, ARCO, EXXON and
contractors including ABB Randall, Bechtel, and M.W. Kellogg.
 
     Cold Boxes.  The Company is a leading designer and fabricator of cold
boxes. Cold boxes are highly engineered systems used to reduce significantly the
temperature of gas mixtures to the point where component gases liquefy and can
be separated and purified for further use in multiple industrial, scientific and
commercial applications. In the industrial gas market, cold boxes are used to
separate air into its major atmospheric components, including nitrogen, oxygen
and argon, used in a diverse range of applications such as the quick-freezing of
food, wastewater treatment and industrial welding. In the hydrocarbon processing
market, the Company's cold box systems are used in natural gas processing and in
the petrochemical industry. The construction of a cold box generally consists of
one or more heat exchangers and other equipment packaged in a "box" consisting
of metal framing and a complex system of piping and valves. Cold boxes, which
are designed and fabricated to order, sell in the approximate price range of
$500,000 to $10 million, with the majority of cold boxes priced between $1
million and $2 million. In anticipation of growing demand for high purity
atmospheric gases and for hydrocarbon applications, the Company increased its
cold box manufacturing capacity and improved its shipping ability in 1995 by
establishing a fabrication facility in New Iberia, Louisiana.
 
     The Company has a number of competitors for fabrication of cold boxes,
including E.S. Fox, Ivor J. Lee, McShane and NAPTech. In addition, the Company's
customers may decide to fabricate cold boxes themselves, purchasing the majority
of the components from third parties including the Company. Principal customers
for the Company's cold boxes include Air Liquide, ABB Randall, AMOCO, Bechtel,
BOC, MG Industries, M.W. Kellogg, Mesa Petroleum and Praxair.
 
     Cryogenic Storage Tanks.  The Company is a leading supplier of cryogenic
tanks, trailers, intermodal containers and railcars. Using sophisticated vacuum
insulation systems placed between inner and outer tanks, these tanks are able to
store and transport liquefied industrial gases and hydrocarbon gases at
temperatures nearing absolute zero. The Company has experienced substantial
growth in its storage tank sales as the demand for liquefied industrial gases
and liquefied hydrocarbon gases has increased, particularly within the
semiconductor industry for use in the microchip manufacturing process. Customers
for the Company's cryogenic storage tanks include industrial gas producers,
chemical producers, manufacturers of electrical components and businesses in the
oil and natural gas industry. Prices for the Company's cryogenic storage tanks
range from $25,000 to $500,000. Principal customers for the Company's cryogenic
storage tanks are AGA, Air Liquide, Air Products, BOC, Jack B. Kelly and
Praxair. The Company competes chiefly with MVE and Harsco for cryogenic storage
tank customers.
 
     Cryogenic Components.  The Company's line of cryogenic components,
including high pressure cryogenic pumps, valves, vacuum jacketed piping systems
and specialty components, are recognized in the market for their reliability,
quality and performance. These products are sold to the Company's heat exchanger
and cold box customers in the industrial gas and hydrocarbon processing
industries, as well as to a diverse group of customers in those and other
industries. The Company competes with a number of other suppliers of cryogenic
components, including MVE, Cryogenic Industries, CCI and Acme Cryogenics.
 
     Special Products.  The Company designs and manufactures thermal vacuum
systems marketed to a customer base that includes the aerospace industry,
government agencies, universities and national research facilities. The Company
is a leading domestic supplier of space simulation systems used to test
satellites and related components. The Company also manufactures large vacuum
chambers for telescope mirror aluminizing, a process in which aluminum is
vaporized to coat the surface of a large telescope mirror to restore its
reflectivity. Management believes that the Company, as a pioneer in the
development of this technology, has supplied the majority of these
 
                                       24
<PAGE>   26
 
systems worldwide. The Company's major competitors in the market for thermal
vacuum products and systems for aerospace and research applications include
Tenney Vacuum and Bemco.
 
     The Company's experience and technological advancements in the high-vacuum
area have resulted in its involvement, commencing in 1995, in equipping the LIGO
project, a scientific research project sponsored by the National Science
Foundation and jointly managed by the Massachusetts Institute of Technology and
the California Institute of Technology. The observatories will be dedicated to
the detection and measurement of cosmic gravitational waves and the harnessing
of these waves for scientific research. The Company has a three-year contract
under which it supplies all of the required LIGO vacuum equipment, including
vacuum chambers, large pipe spools, valves, vacuum pumps, controllers and
modular clean rooms. Management believes that expertise in the field of high
vacuum technology developed by the Company through its involvement in the LIGO
project may have a number of new commercial applications.
 
     The Company produces small diameter stainless steel tubing for sale to
distributors to satisfy their customers' requirements for quick delivery. The
Company's manufacturing strategy is to focus on custom sizes and smaller
production runs, which management believes gives the Company a competitive
advantage in providing a superior quality product while meeting customer demands
for dependable, fast delivery. With its production and marketing efforts
directed principally to customers relying on prompt delivery, the Company is
able to compete primarily on the basis of service rather than price. Numerous
manufacturers of stainless steel tubing are able to compete with the Company in
this market.
 
BUSINESS STRATEGY
 
     Recognized as a leader in the design, engineering and fabrication of
cryogenic systems and equipment, the Company currently faces the challenge of
enhancing its leadership position in markets that are global and growing.
Management expects continued strong demand for cryogenic products by the
industrial gas and hydrocarbon processing markets in North America and in
developed countries overseas. In addition, the accelerated pace of
industrializing efforts by emerging economies holds new and promising growth
opportunities for the Company to penetrate markets where its products currently
have little or no presence. To position the Company for continued growth in an
expanding international marketplace, management has developed the following five
key strategies:
 
     Focus on High-Margin, Niche Products.  The Company has developed a
particular expertise in the design, engineering and manufacture of cryogenic
systems and equipment. The Company will continue to focus on markets requiring
such specialized engineering and technical capability, rather than on
broader-based markets in which competition is largely based on price. The
Company believes that, by focusing on the market niche for cryogenic
applications, it has fewer competitors and higher margins for its products than
producers in markets that use standardized or high-volume products. The
Company's gross margin in the first six months of 1997 was 30.5%.
 
     Leveraging Customer Relationships.  The Company's engineers and sales
personnel work closely with its customers to customize and improve the
performance of its products and to develop and design new products. Through this
continued interaction the Company has built and sustained long-term
relationships with many of its major customers. Most of the Company's largest
customers have been customers of the Company for the last 10 years or more, and
a substantial quantity of the Company's annual sales are made to the same major
customers. As the Company's customers grow domestically and internationally,
they take the Company's products into new growth markets. Virtually all of the
Company's 1996 international sales were made to its long-term customers and
their international affiliates.
 
     Expanding International Direct Sales.  Although the Company is a leading
producer of cryogenic products and systems in North America, its direct sales of
such products outside North America are
 
                                       25
<PAGE>   27
 
relatively modest. In 1996, the Company's international sales constituted
approximately 25% of the Company's total sales. Most of its international sales
in 1996 were to North American customers which incorporated the Company's
products into their own exported products. The Company believes that demand for
the Company's products both in developed countries and emerging economies is
accelerating. The Company is in the process of "globalizing" its marketing to
increase its sales to customers in international markets. The Company intends to
expand its independent sales representative network outside North America in
order to strengthen its market share in selected markets in South America, the
Pacific Rim and the Middle East.
 
     Continued Emphasis on Operating Efficiencies.  The Company has devoted
considerable efforts to maximizing its production efficiency. Management
believes that such efforts have resulted in substantial improvements in
throughput, utilization of existing capacity and organizational efficiency,
which in turn have contributed to higher marginal returns. The Company intends
to continue to seek ways to improve its operating performance.
 
     Pursuing Strategic Acquisitions.  A key component of the Company's growth
strategy is the acquisition of complementary businesses that can effectively
increase the Company's market share and operating efficiencies, while
simultaneously expanding the Company's customer base and presence in geographic
regions which it does not currently serve. As it proceeds with efforts to
penetrate international markets, the Company anticipates extending its
operations overseas through one or more acquisitions abroad. The Company
continually reviews acquisition opportunities, and management believes that a
number of complementary acquisition opportunities exist. Management believes
that the combination of the high level of ability and experience of its senior
managers in evaluating and consummating acquisition opportunities, along with
the Company's low debt levels following the Offering and working capital
requirements, position the Company favorably to complete strategic acquisitions.
 
     Management anticipates that its experience in managing acquired businesses
will facilitate the execution of its acquisition strategy. The Company is a
successor to a group of complementary businesses acquired commencing in 1986
with the purchase of ALTEC, which had net sales of $13.3 million in that year.
Since the acquisition of ALTEC, the Company has grown to $148.4 million in net
sales in 1996 primarily through complementary acquisitions which subsequently
were integrated successfully into the Company's operations. The addition of
Cryenco's business to the Company's operations in July 1997 represents the most
recent effort by the Company to expand by acquiring complementary businesses.
The following businesses have been acquired and consolidated into the Company.

ENGINEERING AND PRODUCT DEVELOPMENT
 
     The Company's engineering and product development activities are primarily
associated with assisting in the design of products or modifications to execute
specific customer orders. The Company's engineering, technical and marketing
employees actively assist customers in specifying their needs and in determining
appropriate products to meet those needs. For example, the Company's product
development activities led to the introduction of the Core-in-Kettle(R) heat
exchanger in 1990, which has met with widespread customer acceptance by the
hydrocarbon processing market. The Company also has invested in the development
of new heat exchanger fins to enhance the performance of its products. A portion
of the Company's engineering expenditures typically are charged to customers
either as a separate item or as a part of product cost. The Company does not
devote a material amount of resources to unfunded research and development
activities.
 
COMPETITION
 
     Management believes the Company can compete effectively for new projects
around the world and that it is a leading competitor in its markets. Competition
is based primarily on performance and the ability to provide the design,
engineering, fabrication and manufacturing capabilities required to complete
projects in a timely and cost-efficient manner. Contracts are usually awarded on
a competitive bid basis. Quality, technical expertise and timeliness of
completion are the principal competitive factors within the industry. Price and
terms of sale are also important competitive factors but only after technical
expertise and ability to perform have been established. Because reliable market
share data are not available, it is difficult to estimate the Company's exact
position in its markets, although the Company believes it ranks among the
leaders in its markets.
 
MARKETING
 
     The Company's principal operating units currently market products and
services in North America primarily through 37 direct sales personnel, and
supplement these direct sales through 45 independent sales representatives and
distributors. The technical and custom design nature of the Company's products
requires a professional, highly trained sales force. Each salesperson is
expected to develop a highly specialized knowledge of one product or group of
products and to sell that product or group of products in all markets in which
the product is used, rather than to sell many products to a single market.
Substantially all of the Company's sales personnel have engineering or technical
experience.
 
     The Company uses independent sales representatives nearly exclusively to
conduct its sales in the foreign countries which the Company serves. These
independent sales representatives supplement the Company's direct sales force in
dealing with language and cultural matters. The Company's domestic and foreign
independent sales representatives earn commissions on sales which vary by
product type.

ORDERS AND BACKLOG
 
     The Company considers orders to be those for which the Company has received
a signed purchase order or other written contract from the customer. Such orders
are included in backlog until recognized as revenue or cancelled. The table
below sets forth orders and backlog for the periods presented.

</TABLE>
 
     The Company has experienced growth in orders and backlog since 1994 in the
industrial gas market. The acquisition of Cryenco should further increase
orders, particularly for this market. Hydrocarbon processing market orders have
been steady for the last 18 months at approximately a $50 million annualized
rate, resulting in increased backlog because of the long lead time for the
typical hydrocarbon project. Special products orders in 1995 include the $39.1
million LIGO project which is a three-year project running through 1998. The
reduction in backlog in special products is primarily the result of progress in
completing this order.
 
     Approximately half of the June 30, 1997 backlog is scheduled to be
recognized as sales during 1997, and the remainder is scheduled to be recognized
as sales in 1998. The Company's backlog fluctuates from time to time and the
amounts set forth above are not necessarily indicative of future backlog levels
or the rate at which they will be recognized as sales.
 
CUSTOMERS
 
     Ten customers accounted for 53% of consolidated sales in 1996. The
Company's sales to particular customers fluctuate from period to period.
Management believes the Company's relationships with its customers are good.
 
PATENTS AND TRADEMARKS
 
     Although the Company has a number of patents, trademarks and licenses
related to its businesses, no one of them or related group of them is considered
by the Company to be of such importance that its expiration or termination would
have a material adverse effect on the Company's businesses. In general, the
Company depends upon technological capabilities, manufacturing quality control
and application of know-how, rather than patents or other proprietary rights in
the conduct of its business.
 
     The Company holds a group of patents for its Ryan/Holmes technology, which
is used primarily in treating associated gases produced from tertiary oil
recovery projects. In addition to fabricating recovery plants on a turnkey basis
for customers, the Company also grants licenses under this
 
                                       28
<PAGE>   30
 
technology to customers for use in their own construction and operation of such
facilities. The revenues received by the Company attributable to this technology
are not material.
 
     The Company has a licensing agreement with Praxair under which the Company
licenses technology related to the design of nitrogen rejection units, a type of
cold box used in the natural gas processing industry to purify methane by the
removal of nitrogen. The agreement provides for the joint marketing by the
Company and Praxair of products using the licensed technology, prohibits the
sale of such products to certain competitors of Praxair and may be terminated by
either party upon not less than six months' notice to the other party.
 
RAW MATERIALS AND SUPPLIERS
 
     The Company manufactures most of the products it sells. The raw materials
used in manufacturing include aluminum fin stock, brazing sheets, bars, plate
and piping, stainless steel hollows, strip, heads, plate and piping, carbon
steel heads and plate, and 9% nickel steel heads and plate. Most raw materials
are available from multiple sources of supply.
 
     Commodity metals used by the Company have experienced fluctuations in
price. The Company has generally been able to recover the costs of such price
increases through its contracts with customers. The Company foresees no acute
shortages of any raw materials which would have a material adverse effect on its
operations.
 
EMPLOYEES
 
     As of August 1, 1997, the Company had approximately 1,250 employees,
including approximately 340 salaried, 360 union hourly and 550 non-union hourly
employees. The salaried employees included approximately 120 engineers and
draft-persons and 220 other professional, technical and clerical personnel.
 
     The Company is a party to two collective bargaining agreements. ALTEC's
agreement with the International Association of Machinists and Aerospace Workers
covering 267 employees expires February 7, 1998. PEI's agreement with the
International Brotherhood of Boilermakers, Iron Ship Builders, Blacksmiths,
Forgers and Helpers covering 93 employees expires August 27, 1999. Since the
acquisition of each of its operating units, the Company has not had any work
stoppages or strikes. The Company believes its employee relations are good. See
"Risk Factors -- Collective Bargaining Agreements."
 
FACILITIES
 
     The Company has nine principal manufacturing locations. The Company
occupies a total of approximately 900,000 square feet, with the majority,
approximately 800,000 square feet, devoted to manufacturing, assembly and
storage. Of the approximately 900,000 square feet occupied, approximately
500,000 square feet are owned and 400,000 square feet are occupied under
operating leases. The Company considers its manufacturing facilities sufficient
to meet its current and planned operational needs. The Company leases
approximately 1,500 square feet of space for its executive offices in Eastlake,
Ohio.
 
GOVERNMENT CONTRACTS
 
     In 1996, approximately 11% of the Company's revenues were derived from
contracts or subcontracts with, or funded by, the United States government,
mostly related to LIGO. These contracts and subcontracts contain standard
provisions permitting the government to terminate them at its option, without
cause. In the event of such termination, the Company is entitled to receive
reimbursement on the basis of work completed (costs incurred plus a reasonable
profit). In addition, these contracts and subcontracts are subject to
renegotiation of profits. The Company has
 
                                       29
<PAGE>   31
 
no knowledge of any pending or threatened renegotiation or termination of any
material government contract or subcontract.
 
ENVIRONMENTAL MATTERS
 
     The Company's operations involve and have involved the handling and use of
substances, such as various cleaning fluids used to remove grease from metal,
that are subject to federal, state and local environmental laws and regulations
that impose limitations on the discharge of pollutants into the soil, air and
water, and establish standards for their storage and disposal. The Company
monitors and reviews its procedures and policies for compliance with
environmental laws. Company management is familiar with these regulations, and
supports an ongoing capital investment program to maintain the Company's
adherence to required standards.
 
     As part of its ongoing environmental compliance and monitoring programs,
the Company is voluntarily developing work plans for remediation of
environmental conditions involving certain of its operating facilities. Based
upon the Company's study of the known conditions and its prior experience in
investigating and correcting environmental conditions, the Company estimates
that the potential costs of these site remediation efforts will not have a
material adverse effect on the Company's financial position or liquidity.
Approximately $1.9 million is recorded at June 30, 1997 as reserves for known
environmental matters. These expenditures are expected to be made mostly in the
next 18 to 24 months, if the necessary regulatory agency approvals of the
Company's work plans are obtained. Although the Company believes it has
adequately provided for the cost of all known environmental conditions, the
applicable regulatory agencies could insist upon different and more costly
remediative measures than those the Company believes are adequate or required by
existing law. Except for its continuing remediative efforts described above, the
Company believes that it is currently in substantial compliance with all known
material and applicable environmental regulations.
 
                                   MANAGEMENT

     Schroder & Co. Inc. and McDonald & Company Securities, Inc., as
representatives for the several Underwriters (the "Representatives"), have
advised the Company and the Selling Stockholders that the Underwriters propose
to offer the shares of Common Stock to the public initially at the public
offering price set forth on the cover page of this Prospectus; that the
Underwriters propose initially to allow a concession not in excess of
$          per share to certain dealers, including the Underwriters; that the
Underwriters and such dealers may initially allow a discount of not in excess of
$          per share to other dealers; and that the public offering price and
the concession and discount to dealers may be changed by the Representatives
after the commencement of the Offering.
 
     The Company has granted to the Underwriters an option, expiring at the
close of business on the 30th day after the date of the Underwriting Agreement,
to purchase up to an additional 420,000 shares of Common Stock at the public
offering price less underwriting discounts and commissions, all as set forth on
the cover page of this Prospectus. The Underwriters may exercise the option, in
whole or in part, only to cover over-allotments, if any, in the sale of shares
of Common Stock in connection with the Offering. To the extent that the
Underwriters exercise this option, each Underwriter will be committed, subject
to certain conditions provided in the Underwriting Agreement, to purchase a
number of the additional shares proportionate to such Underwriter's initial
commitment.
 
     The Company has signed an engagement letter providing that for one year
commencing March 1, 1997, Schroder & Co. Inc. will serve as the Company's
exclusive financial advisor, act as its lead financial advisor in transactions
involving divestitures, mergers, acquisitions or the issue of debt or equity for
cash, and have the right to serve as lead manager of any such issue.
 
     The Company, the Selling Stockholders and the Underwriters have agreed to
indemnify each other against certain liabilities, including liabilities under
the Securities Act of 1933 (the "Securities Act").
 
     The Company, its Directors and executive officers, and the Selling
Stockholders have agreed not to offer, sell, contract to sell, or otherwise
dispose of any shares of Common Stock for a period of 180 days after the date of
this Prospectus without the prior written consent of Schroder & Co. Inc.
 
     The Representatives have advised the Company that, pursuant to Regulation
M, certain persons participating in the Offering may engage in transactions,
including stabilizing bids, syndicate covering transactions or the imposition of
penalty bids, which may have the effect of stabilizing or maintaining the market
price of the Common Stock at a level above that which might otherwise
 
                                       33
<PAGE>   35
 
prevail in the open market. A "stabilizing bid" is a bid for or the purchase of
Common Stock on behalf of the Underwriters for the purpose of fixing or
maintaining the price of the Common Stock. A "syndicate covering transaction" is
the bid for or the purchase of Common Stock on behalf of the Underwriters to
reduce a short position incurred by the Underwriters in connection with the
Offering. A "penalty bid" is an arrangement permitting the Representatives to
reclaim the selling concession otherwise accruing to an Underwriter or syndicate
member in connection with the Offering if the shares of Common Stock originally
sold by such Underwriter or syndicate member are purchased by the
Representatives in a syndicate covering transaction and have therefore not been
effectively placed by such Underwriter or syndicate member. The Representatives
have advised the Company that such transactions may be effected on the New York
Stock Exchange or otherwise and if commenced, may be discontinued at any time.

NOTE A -- BASIS OF PREPARATION
 
     The accompanying unaudited condensed consolidated financial statements have
been prepared in accordance with generally accepted accounting principles for
interim financial information and with the instructions to Form 10-Q and Article
10 of Regulation S-X. Accordingly, they do not include all of the information
and footnotes required by generally accepted accounting principles for complete
financial statements. In the opinion of management, all adjustments (consisting
of normal recurring accruals) considered necessary for a fair presentation have
been included. Operating results for the six-month period ended June 30, 1997
are not necessarily indicative of the results that may be expected for the year
ending December 31, 1997.
 
     All share and per-share amounts have been adjusted for a 3-for-2 stock
split which was distributed to shareholders on June 30, 1997.
 
NOTE B -- INVENTORIES

NOTE C -- EARNINGS PER SHARE
 
     In February 1997, the Financial Accounting Standards Board issued Statement
No. 128, Earnings per Share, which is required to be adopted on December 31,
1997. 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 basic earnings per share, the dilutive effect
of stock options will be excluded. The impact is expected to result in basic
earnings per share for the six-months ended June 30, 1997 and 1996 of $.63 and
$.45 per share, respectively. Fully diluted earnings per share for these
quarters should not be materially different than the currently disclosed
earnings per share.
 
NOTE D -- REVENUE RECOGNITION
 
     The Company uses the percentage of completion method of accounting for
significant contracts. In other cases, revenue is recognized using the completed
contract method. Management performs a monthly assessment of major significant
contracts to determine if contract costs will exceed contract revenues. For
those projects where the estimated costs exceed estimated revenues, appropriate
estimated losses are recorded. The effects of any change orders are accounted
for when agreed to by the Company's customers.

                         REPORT OF INDEPENDENT AUDITORS
 
To the Shareholders and Board of Directors
of Chart Industries, Inc.
 
     We have audited the accompanying consolidated balance sheets of Chart
Industries, Inc. and subsidiaries as of December 31, 1996 and 1995, and the
related consolidated statements of operations, shareholders' equity and cash
flows for each of the three years in the period ended December 31, 1996. 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 consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position of
Chart Industries, Inc. and subsidiaries at December 31, 1996 and 1995, and the
consolidated results of their operations and their cash flows for each of the
three years in the period ended December 31, 1996, in conformity with generally
accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
NOTE A -- NATURE OF OPERATIONS
 
     The Company is involved in the engineering and manufacturing of industrial
equipment and systems for the cryogenic and process industries and various
research applications. Substantially all of the Company's sales and trade
accounts receivable are related to the air separation, hydrocarbon and chemical
processing and power generation industries and laboratories related to space and
high physics research located throughout the world. The Company requires
customer advances when appropriate to reduce risk and provide working capital.
Sales to U.S. government funded projects accounted for 11%, 5% and 3% of
consolidated sales in 1996, 1995 and 1994, respectively and an $800,000 accounts
receivable balance at December 31, 1996. Ten customers accounted for 53% of
consolidated sales in 1996.
 
NOTE B -- SIGNIFICANT ACCOUNTING POLICIES
 
     Principles of Consolidation:  The consolidated financial statements include
the accounts of the Company and its subsidiaries. Intercompany accounts and
transactions are eliminated in consolidation. Certain items in previous
financial statements have been reclassified to conform to 1996 presentation.
 
     Cash and Cash Equivalents:  The Company considers all investments with an
initial maturity of three months or less when purchased to be cash equivalents.
The 1996 amount includes $5,104,000 of proceeds and interest income related to
the issuance of the industrial revenue bond in 1996 which have not yet been
released from escrow for the ALTEC expansion (see Note C).
 
     Intangible Assets:  Intangible assets are carried at cost less applicable
amortization and amounted to $2,258,000 at December 31, 1996 and $2,860,000 at
December 31, 1995. The accumulated amortization included in these amounts was
$387,000 and $190,000 in 1996 and 1995, respectively. Intangibles are amortized
on the straight-line method over the periods of expected benefit, but not in
excess of 15 years. Such amounts are classified as other assets in the
accompanying balance sheets. Total amortization was $507,000, $499,000 and
$321,000 in 1996, 1995 and 1994, respectively.
 
     Inventories:  Inventories are stated at the lower of cost or market with
cost being determined by both the last-in, first-out ("LIFO") method
(approximately 75% and 69% of total inventory at December 31, 1996 and 1995,
respectively), and the first-in, first-out ("FIFO") method. The components of
inventory on a first-in, first-out basis are as follows:

     Property, Plant and Equipment:  Property, plant and equipment are stated on
the basis of cost. Expenditures for maintenance, repairs and renewals are
charged to expense as incurred, whereas major betterments are capitalized. The
cost of applicable assets is depreciated over their estimated useful lives.
Depreciation is computed using the straight-line method for financial reporting
purposes and accelerated methods for income tax purposes. The following table
shows original costs and the estimated useful lives of the different types of
assets:

</TABLE>
 
     The property, plant and equipment at PEI was evaluated for impairment
during 1994 and a writedown of $320,000 was included in a restructuring charge
taken in the second quarter of 1994.
 
     Property, plant and equipment along with the intangible assets are
periodically evaluated for impairment. The Company assesses impairment for each
of its operating units by measuring future cash flows against the carrying value
of these long-lived assets. If the future undiscounted cash flows are less than
the carrying amount, an impairment reserve is recorded.
 
     Revenue Recognition:  The Company uses the percentage of completion method
of accounting for significant contracts. 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. Earned revenue on jobs
in process totalled $52.6 million at December 31, 1996. Timing of amounts billed
on contracts varies greatly from contract to contract causing high variation in
working capital needs. Amounts billed on percentage completion jobs in process
totalled $62.6 million at December 31, 1996. The cumulative impact of revisions
in total cost estimates during the progress of work is reflected in the period
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. Otherwise, revenue is recognized when
the products are completed or shipped.
 
     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 amounts reported in the financial
statements and accompanying notes. Actual results could differ from those
estimates especially in regards to the percentage of completion method of
revenue recognition.
 
     Deferred Income Taxes:  The Company and its subsidiaries file a
consolidated federal income tax return. Deferred income taxes are provided for
temporary differences between financial reporting and the consolidated tax
return in accordance with the liability method.
 
     Net Income (Loss) Per Share:  The weighted average number of common shares
and common share equivalents (stock options) outstanding in each year is used to
compute net income (loss) per share.
 
     Employee Stock Options:  The Company has elected to follow Accounting
Principles Board Opinion No. 25, "Accounting for Stock Issued to Employees" (APB
25) and related Interpretations in accounting for its employee stock options.
Under APB 25, because the exercise price of the Company's employee stock options
equals the market price of the underlying stock on the date of grant, no
compensation expense is recognized.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- CONTINUED
 
NOTE C -- LONG-TERM DEBT
 
     The Company currently maintains a consolidated credit and revolving loan
facility ("Facility") which provides for loans of up to $25 million, of which
$10 million may be available for the issuance of letters of credit. The Company
had no borrowings at December 31, 1996 and $11.5 million outstanding at December
31, 1995. The Facility extends to June 30, 1998. The Facility provides the bank
with a secured interest in substantially all of the property, plant and
equipment of the Company.
 
     Under the terms of the Facility, loans (including draws under any proposed
letters of credit) will bear interest, at the Company's option, at a rate equal
to the bank's base rate (8.25 percent at December 31, 1996) or LIBOR plus 1.25
percent per annum. Based on the Company's financial position, the Company and
its banks have agreed to adjust the LIBOR differential on a set schedule. The
Company is also required to pay a commitment fee of .375% per annum on the
unused portion of the Facility, payable quarterly in arrears.
 
     The Facility contains certain covenants and conditions which impose
limitations on the Company and its operating units, including meeting certain
financial tests and the maintenance of certain financial ratios on a
consolidated basis such as: minimum current ratio, minimum net worth, maximum
leverage, minimum interest coverage ratio and minimum fixed charge ratio. As of
December 31, 1996, the Company was in compliance with all covenants and
conditions. The Company has outstanding letters of credit totaling $2,635,000
all backed up by the Facility.
 
     As part of the expansion of the ALTEC facility, the Company issued
Industrial Development Revenue Bonds (IRB) totaling $5 million during 1996 ($4.8
million outstanding at December 31, 1996). The bonds are collateralized by the
equipment related to the expansion. These notes pay interest at 6.3 percent and
have maturities in the next five years as follows: 1997 -- $361,000;
1998 -- $405,000; 1999 -- $431,000; 2000 -- $459,000 and 2001 -- $489,000. The
Company is required to spend these monies on the current expansion and has
commitments with vendors covering this work. All funds should be released from
escrow by the end of 1997.
 
     The Company was able to repay during 1996 all remaining maturities of the
notes issued as part of the acquisition of CVI without any early retirement
costs.
 
     Interest paid was $688,000 in 1996, $1,799,000 in 1995, and $800,000 in
1994.
 
NOTE D -- RESTRUCTURING CHARGE
 
     During 1994, the Company elected to substantially restructure PEI's
operations. A restructuring charge was recorded during the second quarter of
1994 for the costs of employee severance (approximately $1.3 million),
lease-buyouts, excess inventory and machinery disposals (approximately $1.2
million) and the eventual sale of the land and buildings and other expenses
associated with the anticipated plant closure.
 
     In October 1994, the Company announced its intention to maintain the
operations of PEI at its current Plaistow, New Hampshire location. The decision
to continue operations followed the termination of a proposed joint venture and
identification of substantial restructuring opportunities and cost reductions at
the Plaistow facility. In addition, PEI reached an agreement with its union work
force which is expected to permit meaningful operating concessions.
 
     The original restructuring charge was reduced by $1.1 million reflecting
reductions in employee severance, lease buyouts and costs related to the
eventual sale of the land and buildings. The remaining $2.15 million
restructuring charge includes severance and other employee-related costs due to
the restructuring, write-off of inventory and equipment related to products no
longer

manufactured, certain costs of the terminated joint venture negotiations and the
impairment in value of the land and building.
 
NOTE E -- 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. At December 31, 1996, the
Company had net operating loss carryforwards for income tax purposes of $947,000
that expire in years 2003 through 2006. These carryforwards resulted from the
Company's 1991 acquisition of Process Engineering and are subject to Separate
Return Limitation Year (SRLY) and Section 382 limitations imposed by the
Internal Revenue Code of 1986, as amended, and the regulations thereunder.
Significant components of the Company's deferred tax liabilities and assets are
as follows:

amounts per year of service as negotiated with the employees' collective
bargaining unit. The Company's funding policy is to contribute at least the
minimum funding amounts required by law. Plan assets consist primarily of U.S.
Treasury notes and corporate stocks and bonds.

     Pro forma information regarding net income and earnings per share is
required by FASB Statement No. 123, "Accounting for Stock-Based Compensation",
which also requires that the information be determined as if the Company has
accounted for its employee stock options granted subsequent to December 31,
1994, under the fair value method of that Statement. The fair value for these
options was estimated at the date of grant using a Black-Scholes option pricing
model with the following weighted-average assumptions for 1996 and 1995:
risk-free interest rates of 6.7%; dividend yields of 2%; volatility factors of
the expected market price of the Company's common stock of .38; and a
weighted-average expected life of the option of six (6) years for key employee
options and three (3) years for outside directors options.
 
     The Black-Scholes option valuation model was developed for use in
estimating the fair value of traded options which have no vesting restrictions
and are fully transferable. In addition, option valuation models require the
input of highly subjective assumptions including the expected stock price
volatility. Because the Company's Key Employee and Outside Directors stock
options have characteristics significantly different from those of traded
options, and because changes in the subjective input assumptions can materially
affect the fair value estimate, in management's opinion, the existing models do
not necessarily provide a reliable single measure of the fair value of these
stock options.
 
     For purposes of pro forma disclosures, the estimated fair value of the
options is amortized to expense over the options' vesting period. The Company's
pro forma information follows (in thousands except for earnings per share
information):

     As part of its ongoing environmental compliance and monitoring programs,
the Company is voluntarily developing work plans for environmental conditions
involving certain of its operating facilities. Based upon the Company's study of
the known conditions and its prior experience in investigating and correcting
environmental conditions, the Company estimates that the potential costs of
these site remediation efforts will not be material to the financial position or
liquidity of the Company. Approximately $1.4 million for these costs is recorded
in accrued liabilities at December 31, 1996 for known environmental matters.
These expenditures are expected to be made mostly in the next year, if the
necessary regulatory agency approvals of the Company's work plans are obtained.
Though the Company believes it has adequately provided for the cost of all known
environmental conditions, the applicable regulatory agencies could insist upon
different and more costly remediative measures than those the Company believes
are adequate or required by existing law. Otherwise, the Company believes that
it is currently in compliance with all known material and applicable
environmental regulations.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- CONTINUED
 
NOTE K -- SUBSEQUENT EVENT
 
     All shares of common stock (except for the shares outstanding in the
Consolidated Statements of Shareholders' Equity) and per share amounts have been
adjusted to give retroactive effect to a three-for-two stock split effected in
the form of a 50% stock dividend distributed on June 30, 1997 to shareholders of
record on June 16, 1997.
 
     In February 1997, the Financial Accounting Standards Board issued Statement
No. 128, "Earnings Per Share," which is required to be adopted on December 31,
1997. 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 stock options will be excluded. The impact of Statement 128 on the
calculation of primary and fully diluted earnings per share for these years is
not expected to be material.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     Section 145 of the Delaware General Corporation Law of the State of
Delaware sets forth the conditions and limitations governing the indemnification
of officers, directors and other persons.
 
     Article VII of the Company's Amended and Restated By-Laws (the "By-Laws")
provides in part that the Company shall indemnify any Director or officer who
was or is a party or is threatened to be made a party to any threatened, pending
or completed action, suit or proceeding, either civil, criminal, administrative
or investigative, by reason of the fact that he or she is or was a Director or
officer of the Company, or is or was serving at the request of the Company, as a
Director or officer of certain other entities, against all expense, liability
and loss reasonably incurred or suffered by such person in connection with such
action, suit or proceeding, and under certain circumstances, whether or not the
indemnified liability arises or arose from any threatened, pending or completed
action by or in the right of the Company. Responsibility for determinations with
respect to such indemnification shall be made by the Board of Directors, by
independent legal counsel or by the stockholders of the Company.
 
     The Company has also entered into indemnity agreements (the "Indemnity
Agreements") with its Directors and officers that expand the protection provided
to the Company's Directors and officers and are based upon sections of the
General Corporation Law of the State of Delaware and Article VII of the
Company's By-Laws that recognize the validity of additional indemnity rights
granted by agreement. The substantive content of the Indemnity Agreements and
Article VII of the By-Laws is substantially the same except that, pursuant to
the Indemnity Agreements, indemnity is expressly provided for settlements in
derivative actions and partial indemnification is permitted in the event that
the Director or officer is not entitled to full indemnification.
 
     Both the General Corporation Law of the State of Delaware and Article VII
of the Company's By-Laws provide that the Company may maintain insurance to
cover loss incurred pursuant to liability of Directors and officers of the
Company, which insurance, if any, may cover liabilities of Directors and
officers of the Company arising under the Securities Act of 1933, as amended
(the "Securities Act").

     Reference is made to Section 8 of the Underwriting Agreement (Exhibit 1.1
to this Registration Statement) which provides for indemnification of the
Registrant's officers, Directors and controlling persons by the Underwriters
against certain civil liabilities, including liabilities under the Securities
Act.
 
ITEM 16. EXHIBITS.
 
     See Exhibit Index at page E-1 of this Registration Statement.
 
ITEM 17. UNDERTAKINGS.
 
     The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
Registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities
Exchange Act of 1934 (and, where applicable, each filing of an employee benefit
plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of
1934) that is incorporated by reference in the registration statement shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.
 
     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities Act
and is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the Registrant of expenses
incurred or paid by a director, officer or controlling person of the Registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.
 
     The undersigned Registrant hereby undertakes that:
 
          (1) For purposes of determining any liability under the Securities Act
     of 1933, the information omitted from the form of prospectus filed as part
     of this registration statement in reliance upon Rule 430A and contained in
     a form of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or
     (4) or 497(h) under the Securities Act shall be deemed to be part of this
     registration statement as of the time it was declared effective.
 
          (2) For the purpose of determining any liability under the Securities
     Act of 1933, each posteffective amendment that contains a form of
     prospectus shall be deemed to be a new registration statement relating to
     the securities offered therein, and the offering of such securities at that
     time shall be deemed to be the initial bona fide public offering thereof.

certifies that it has reasonable grounds to believe that it meets all of the

                    RESTATED CERTIFICATE OF INCORPORATION
                                      OF
                            CHART INDUSTRIES, INC.


        ARTICLE I:      NAME

        The name of the Corporation is Chart Industries, Inc.

        ARTICLE II:     REGISTERED OFFICE

        The address of the registered office of the Corporation in the State of
Delaware is Corporation Trust Center, 1209 Orange Street, City of Wilmington,
County of New Castle, and the name of its registered agent at that address is
The Corporation Trust Company.

        ARTICLE III:    PURPOSE

        The purpose of the Corporation is to engage in any lawful act or
activity for which corporations may be organized under the Delaware General
Corporation Law, as the same exists or may hereafter be amended (provided that
the effect of any such amendment shall be prospective only) (the "Delaware
Law").

        ARTICLE IV:     AUTHORIZED CAPITAL STOCK

        SECTION 1.      NUMBER OF AUTHORIZED SHARES.  The total number of
shares of all classes of stock that the Corporation shall have authority to
issue is Thirty-One Million (31,000,000), consisting of Thirty Million
(30,000,000) shares of common stock, par value $.01 per share (the "Common
Stock"), and One Million (1,000,000) shares of preferred stock, par value $.01
per share (the "Preferred Stock").  Each of the issued shares of Common Stock
is hereby changed by splitting each such share into 16,609.1 shares, and the
par value of the subdivided shares is adjusted so that the par value of each
such share of Common Stock of the Corporation shall equal $0.01 per share. 
Said change and adjustment shall become effective upon filing of this Amended
and Restated Certificate of Incorporation with the Secretary of State of
Delaware.

        SECTION 2.      DIVIDENDS AND DISTRIBUTIONS.  Subject to the
preferences applicable to Preferred Stock outstanding at any time, the holders
of shares of Common Stock shall be entitled to receive such dividends, payable
in cash or otherwise, as may be declared thereon by the Board of Directors from
time to time out of assets or funds of the Corporation legally available
therefor, provided that each share of Common Stock shall be equal in respect of
rights to dividends and other distributions in cash, stock or property of the
Corporation.

        SECTION 3.      VOTING RIGHTS.  Each share of Common Stock shall
entitle the holder thereof to one vote on all matters submitted to a vote of
the stockholders of the Corporation.
<PAGE>   3
rights of holders of Common Stock shall be subject to the powers, preferences
and rights, and the qualifications, limitations or restrictions thereof, of the
Preferred Stock.  The right of any holder of any class of stock to vote
cumulatively is expressly denied.

        SECTION 4.      ACTION BY WRITTEN CONSENT.  The right of the
stockholders to take any action by consent in writing without a regular or
special meeting of the stockholders is expressly denied.

        SECTION 5.      PREFERRED STOCK.  The Board of Directors of the
Corporation may by resolution authorize the issuance of shares of Preferred
Stock from time to time in one or more series.  Shares of Preferred Stock that
are redeemed, purchased or otherwise acquired by the Corporation may be
reissued except as otherwise provided by law.  The Board of Directors is hereby
authorized to fix or alter the designations, powers and preferences, and
relative, participating, optional or other rights, if any, and qualifications,
limitations or restrictions thereof, including, without limitation, dividend
rights (and whether dividends are cumulative), conversion rights, if any,
voting rights (including the number of votes, if any, per share, as well as the
number of members, if any, of the Board of Directors each series of Preferred
Stock may be entitled to elect), rights and terms of redemption (including
sinking fund provisions, if any), redemption price and liquidation preferences
of any wholly unissued series of Preferred Stock, and the number of shares
constituting any such series and the designation thereof, and to increase or
decrease the number of shares of any such series subsequent to the issuance of
shares of such series, but not below the number of shares of such series then
outstanding.  Notwithstanding the foregoing, the Board of Directors shall have
no power to alter the rights of any shares of Preferred Stock then outstanding
without the consent of the holders of a majority of the outstanding shares the
rights of which are to be altered.

        SECTION 6.      DISTRIBUTIONS UPON LIQUIDATION.  In the event of any
dissolution, liquidation or winding up of the affairs of the Corporation in
accordance with applicable law, whether voluntary or involuntary, after payment
or provision for payment of the debts and other liabilities of the Corporation,
the holders of each series of Preferred Stock, if any, shall be entitled to
receive, out of the net assets of the Corporation, an amount for each share of
such series of Preferred Stock equal to the amount fixed and determined by the
Board of Directors in the resolution or resolutions creating such series and
providing for the issuance of such shares, plus an amount equal to all
dividends accrued and unpaid on shares of such series to the date fixed for
distribution, and no more, before any of the assets of the Corporation shall be
distributed or paid over to the holders of Common Stock.  After payment in full
of said amounts to the holders of Preferred Stock of all series, the remaining 
assets and funds of the Corporation shall be divided among and paid
to the holders of shares of Common


                                     -2-
<PAGE>   4
Stock. If, upon such dissolution, liquidation or winding up, the assets of the
Corporation distributable as aforesaid among the holders of Preferred Stock of
all series shall be insufficient to permit full payment to them of said
preferential amounts, then such assets shall be distributed ratably among such
holders of Preferred Stock in proportion to the respective total amounts that
they shall be entitled to receive as provided in this Section 6.

        ARTICLE V:  BOARD OF DIRECTORS

        A. The Board of Directors shall consist of not less than three (3) nor
more than fifteen (15) members and shall be divided into three classes, Class
I, Class II and Class III, which shall be as nearly equal in number as
possible. Subject to the foregoing limitations, the number of Directors shall
be fixed by, or in the manner provided in, the By-laws of the Corporation. In
the event the total number of Directors is not divisible by three (3), an extra
Director shall be assigned to Class I if there is one (1) extra Director to be
assigned among the classes, and an extra Director shall be assigned to each of
Classes I and II if there are two (2) extra Directors to be assigned among the
classes. The Directors to be elected at each annual meeting of stockholders
shall be only the members of the class whose term of office then expires. The
term of office of the initial Directors in each respective class shall be as
follows: (a) Directors in Class I shall hold office until the first annual
meeting of stockholders, which shall be held in 1993; (b) Directors in Class II
shall hold office until the annual meeting of stockholders held in 1994; and
(c) Directors in Class III shall hold office until the annual meeting of
stockholders held in 1995. Each Director elected at any stockholders' meeting
commencing with the 1993 annual meeting shall serve for a term ending on the
date of the third annual meeting of stockholders following the meeting at which
such Director was elected. Elections of Directors need not be by written ballot
unless the By-laws of the Corporation shall so provide.

        B. In the event of any increase or decrease in the authorized number of
Directors, (a) each Director then serving as such shall nevertheless continue
as a Director of the class of which he or she is a member until the expiration
of his or her current term, or his or her prior death, retirement, resignation,
or removal, and (b) the newly created or eliminated directorships resulting
from such increase or decrease shall be apportioned by the Board of Directors
among the three classes of Directors as provided above in this Article V.

        C. Notwithstanding any of the foregoing provisions of this Article,
each Director shall serve until his or her successor is elected and qualified
or until his or her prior death, retirement, resignation or removal. No
Director may be removed except for cause and (in addition to the affirmative
vote which may be required of the holders of any series of Preferred Stock
which may then be outstanding) by the affirmative vote of the holders of at


                                     -3-









<PAGE>   5
least a majority of the outstanding shares of Common Stock of the Corporation
entitled to vote thereon. Should a vacancy occur or be created, whether arising
through death, resignation or removal of a Director or through an increase in
the number of Directors, such vacancy shall be filled by a majority vote of the
Directors then in office, or by the sole remaining Director if only one
Director remains in office. A Director so elected to fill a vacancy shall serve
for the remainder of the present term of office of the class to which he or she
was elected.

        Notwithstanding the foregoing, during any period in which the holders
of any one or more series of Preferred Stock, voting as a class, shall be
entitled to elect a specified number of Directors by reason of dividend
arrearages or other contingencies giving them the right to do so, then and
during such time as such right continues, (1) the then otherwise authorized
number of Directors shall be increased by such specified number of Directors
and the holders of shares of such series of Preferred Stock, voting as a class,
shall be entitled to elect such specified number of Directors in accordance
with the provisions of such Preferred Stock; (2) each such additional Director
shall serve until the next annual meeting at which the term of office of his or
her class shall expire and until his or her successor shall be elected and
shall qualify, or until his or her right to hold such office terminates
pursuant to the provisions of such Preferred Stock or series, whichever occurs
earlier. Whenever the holders of shares of such series of Preferred Stock are
divested of such right to elect Directors pursuant to the provisions of such
Preferred Stock or series, the terms of office of all Directors elected by the
holders of such series of Preferred Stock pursuant to such provisions, or
elected to fill any vacancies resulting from the death, resignation or removal
of Directors so elected by the holders of such Preferred Stock or series, shall
forthwith terminate and the authorized number of Directors shall be reduced
accordingly.

        ARTICLE VI:  BUSINESS COMBINATIONS

        A. In addition to the affirmative vote which may be required of the
holders of any series of Preferred Stock which may then be outstanding, the
affirmative vote of the holders of not less than sixty-six and two-thirds
percent (66-2/3%) of the outstanding shares of Common Stock of the Corporation,
which shall include the affirmative vote of at least fifty-one percent (51%) of
the outstanding shares of Common Stock held by stockholders other than the
"Related Person" (as hereinafter defined), shall be required for the approval
or authorization of any "business combination" (as hereinafter defined) of the
Corporation with any Related Person; provided, however, that such 66-2/3% and
51% voting requirements shall not be applicable if the stockholders are asked
to approve or authorize a particular business combination which has been
authorized and proposed to the stockholders by action of the Board of Directors
of the Corporation by the affirmative vote of a



                                     -4-







<PAGE>   6
majority of all Directors then in office, or if the stockholders are asked to
approve or authorize a particular business combination as to which both of the
following conditions are satisfied:

                (1) the aggregate amount of the cash and the fair market value
        of the consideration other than cash to be received per share by the
        holders of the Common Stock of the Corporation in such business
        combination is at least equal to the greater of (a) the highest price
        per share (including any brokerage commissions, transfer taxes and
        soliciting dealer's fees) paid or agreed to be paid by the Related
        Person to acquire beneficial ownership of any share of such Common
        Stock (with appropriate adjustments for recapitalizations, and for
        stock splits, stock dividends and like distributions); (b) the highest
        price per share (including any brokerage commissions, transfer taxes
        and soliciting dealer's fees) paid by any person to acquire beneficial
        ownership of any share of such Common Stock on the open market at any
        time during the twenty-four month period immediately prior to the
        taking of such vote, or (c) the per share book value of such Common
        Stock at the end of the calendar quarter immediately preceding
        the taking of such vote; and

                (2) the consideration to be received by holders of Common Stock
        in such business combination shall be in the same form and of the same
        kind as the most favorable form and kind of consideration paid by the
        Related Person in acquiring beneficial ownership of any of the shares
        of Common Stock already held, directly or indirectly, by it.

The determination of a majority of the "Disinterested Directors" of the
Corporation, made in good faith and based upon information known to them after
reasonable inquiry, shall be conclusive as to all facts necessary for
compliance with this Article, including without limitation (i) whether any
person, partnership, corporation or firm is a Related Person or affiliate or
associate as defined herein, and (ii) the most favorable form and kind of
consideration paid by the Related Person in acquiring beneficial ownership of
shares of Common Stock.

        B. For the purposes of this Certificate of Incorporation:

           (1) The term "business combination" shall mean (a) any merger or
consolidation of the Corporation with or into a Related Person, (b) any sale,

assets of the Corporation (including, without limitation, any voting securities
of a subsidiary) or of a subsidiary, to a Related Person, (c) any merger or
consolidation of a Related Person with or into the Corporation or a subsidiary
of the Corporation, (d) any sale, lease, exchange, transfer or other
disposition of all or any substantial part of the assets of a Related Person to
the

Corporation or a subsidiary of the Corporation, (e) the reclassification of the
shares of stock of the Corporation generally possessing voting rights in
elections for Directors, the purchase by the Corporation of such shares, or the
issuance by the Corporation of shares of any securities convertible thereto or
exchangeable therefor which in any such case has the effect, directly or
indirectly, of increasing the proportionate share of the outstanding shares of
any class of equity or convertible securities of the Corporation which are
directly or indirectly owned by any Related Person, or (f) any agreement,
contract or other arrangement providing for any of the transactions described
in this definition of business combination.

        (2) The term "Related Person" shall mean and include any individual,
corporation, partnership  or other person or entity which, together with its
"affiliates" and "associates," "beneficially" owns (as those terms are defined
in the Securities Exchange Act of 1934 and in the rules thereunder), in the
aggregate, 5% or more of the outstanding shares of Common Stock of the
Corporation, and any "affiliate" or "associate" of any such individual,
corporation, partnership or other person or entity; provided that shares held
or over which such entity has the power to vote or otherwise control as a
trustee, plan administrator, officer of the Corporation or in a similar
capacity under an employee benefit plan of the Corporation or any employee
benefit plan of an affiliate of the Corporation shall not be deemed to be
beneficially owned for purposes of this definition.

        (3) The term "substantial part" shall mean more than ten percent (10%)
of the total consolidated assets of the Corporation as of the end of its most
recent fiscal year ending prior to the time the determination is made.

        (4) Without limitation, any shares of Common Stock of the Corporation
which any Related Person has the right to acquire pursuant to any agreement, or
upon exercise of conversion rights, warrants or options, or otherwise, shall be
deemed beneficially owned by such Related Person.

        (5) The term "consideration other than cash" shall include, without
limitation, outstanding Common Stock of the Corporation retained by its
existing stockholders in the event of a business combination with a Related
Person in which the Corporation is the surviving corporation.

        (6) The term "Disinterested Director" means any member of the Board
of Directors of the Corporation who is not the Related Person or an affiliate
or associate of the Related Person and was a member of the Board prior to the
time that the Related Person became the Related Person, and any successor of a
Disinterested Director who is not the Related Person or an affiliate or

        ARTICLE VII: AMENDMENTS

        No amendment of this Certificate of Incorporation shall be effective to
amend, alter, repeal or change the effect of any of the provisions of Articles

Corporation by the affirmative vote of a majority of the Directors then in
office.

        ARTICLE VIII: LIABILITY AND INDEMNIFICATION

        A. A Director of the Corporation shall not be personally liable to the
Corporation or its stockholders for monetary damages for breach of fiduciary
duty as a Director, except for liability (i) for any breach of the Director's
duty of loyalty to the Corporation or its stockholders, (ii) for acts or
omissions not in good faith or which involve intentional misconduct or a

or these By-laws, a majority of the outstanding shares of such class or classes,
present in person or represented by proxy, shall constitute a quorum entitled to
take action with respect to that vote. If such quorum shall not be present or
represented by proxy at any meeting of the stockholders, the stockholders
present in person or represented by proxy shall have power to adjourn the

member or members thereof present at any meeting and not disqualified from
voting, whether or not he or they constitute a quorum, may unanimously appoint
another member of the Board of Directors to act at the meeting in the place of
any such absent or disqualified member. Subject to the limitations of Section

under any provision of the Delaware General Corporation Law or of the
Certificate of Incorporation or these By-laws, a written waiver thereof, signed
by the person or persons entitled to said notice, whether before or after the
time stated therein, shall be deemed equivalent to notice. Attendance of a

Chairman of the Board shall be final unless expressly overruled or modified by
action of the Board of Directors, in which event such action of the Board of
Directors shall be conclusive of the matter. Nothing contained herein shall
preclude any officer from serving the Corporation in any other capacity,
including that of Director, or from serving any of its stockholders,
subsidiaries or affiliated corporations in any capacity, and receiving a proper

person who is or was a Director or officer of the Corporation, or is or was
serving at the request of the Corporation as a director or officer of another
corporation, partnership, joint venture, trust or other enterprise, to the full
extent permitted by Section 145 of the Delaware General Corporation Law, as

authorized by the Board of Directors may be effected at any time for the
Corporation from any bank, trust company or other institution, or from any firm,
corporation or individual. All bonds, debentures, notes and other obligations or
evidences of indebtedness of the Corporation issued for such loans shall be

authorized by the Board of Directors, any part of or all the properties,
including contract rights, assets, business or good will of the Corporation,
whether then owned or thereafter acquired, may be mortgaged, pledged,
hypothecated or conveyed or assigned in trust as security for the payment of
such bonds, debentures, notes and other obligations or evidences of indebtedness
of the Corporation, and of the interest thereon, by instruments executed and
delivered in the name of the Corporation.

        Section 3. BANKING. All funds of the Corporation not otherwise employed
shall be deposited from time to time to the credit of the Corporation in such
banks, trust companies or other depositaries as the Board of Directors may
authorize. The Board of Directors may make such special rules and regulations
with respect to such bank accounts, not inconsistent with the provisions of
these By-laws, as it may deem expedient. For the purpose of deposit and for the
purpose of collection for the account of the Corporation, checks, drafts and
other orders for the payment of money which are payable to the order of the
Corporation shall be endorsed, assigned and delivered by such person or persons

any certificate or certificates theretofore issued by the Corporation alleged to
have been lost, stolen or destroyed, upon the making of an affidavit of that
fact by the person claiming the certificate for stock to be lost, stolen or
destroyed. When authorizing such issue of a new certificate or certificates, the
Board of Directors may, in its discretion and as a condition precedent to the
issuance thereof, require the owner of such lost, stolen or destroyed
certificate or certificates, or his legal representative, to advertise the same
in such manner as it shall require and/or to give the Corporation a bond in such

date also shall not be more than sixty (60) days prior to such action.  A
