                                 PART I

ITEM 1.  BUSINESS

Aztec Manufacturing Co. ("Aztec" or the "Company") was incorporated under the
laws of the state of Texas on March 26, 1956.  Aztec, through its subsidiaries,
operates under three segments.  These segments are Electrical Products,
Galvanizing and Oil Field Products, which are discussed further below.

Aztec started in 1956 as an oil field-related company servicing oil field supply
companies and steel mills. The Company was located in Fort Worth, Texas, but
subsequently moved to Crowley, Texas. In 1965, Aztec diversified into the
galvanizing industry and opened its first location in Crowley, Texas. Oil field
operations were expanded with the opening of its Houston facility in 1967.
Galvanizing operations were expanded with the formation of Aztec Industries in
Jackson, Mississippi in 1969, the opening of a galvanizing facility in Houston
in 1975, the acquisition of Automatic Processing in Moss Point, Mississippi and
the formation of Aztec Mfg. Co. - Waskom in Waskom, Texas in 1986. Aztec added
to its Oil Field Products Segment in 1986 with the purchase of Parks Machine, a
job shop screw machine facility, located in Crowley, Texas. Aztec closed its
Houston Tubing facility in 1989 due to the depressed domestic oil industry. The
Electrical Products Segment was formed with the purchase of Rig-A-Lite
Partnership, LTD. in Houston, Texas, in March 1990 and the acquisition of The
Calvert Company located in Jackson, Mississippi, in September 1990. Aztec closed
and liquidated Parks Machine in November 1992, due to the low level of oil field
activity. Aztec added to its Electrical Products Segment with the acquisition of
Atkinson Industries, Inc., in March 1993. Gulf Coast Galvanizing, Inc., located
in Citronelle, Alabama, was acquired in January 1994. Aztec completed and opened
in November 1994 a new galvanizing facility near Phoenix in Goodyear, Arizona.
Arkansas Galvanizing, Inc., located in Prairie Grove, Arkansas, was acquired in
February 1996. The Company made three acquisitions in fiscal 1998. Hobson
Galvanizing, Inc. located in Belle Chase, Louisiana was acquired in March 1997,
and International Galvanizers, Inc. located in Beaumont, Texas was acquired in
December 1997. Drilling Rig Electrical Systems, Inc. located in Houston, Texas
was acquired and added to the Company's Electrical Segment in February 1998. The
Company now operates ten galvanizing facilities in six states, four electrical
facilities and one oil field products facility.

A three-year summary of sales, operating profit and identifiable assets by
industry segment is included in Note 10 to the Consolidated Financial Statements
on page 25 of the Registrant's 1998 Annual Report to Shareholders. Such
information is hereby incorporated by reference.

Aztec provides services and manufacturing of products in the following areas:

ELECTRICAL PRODUCTS SEGMENT
This segment includes Rig-A-Lite Partnership, LTD, which manufactures and
assembles lighting fixtures for hostile and hazardous environments in the
industrial market. Rig-A-Lite also engages in the assembly and installation of
electrical components and lighting fixtures on drilling rigs for the petroleum
industry. Drilling Rig Electrical Systems, Inc. (DRESCO) designs, furnishes and
contracts the installation of electrical systems for oil field drilling rigs,
drilling barges, etc. used for the production of oil and natural gas. DRESCO,
acquired in February 1998, operates in conjunction with Rig-A-Lite, utilizing
their lighting products. Also in this segment is The Calvert Company, which
designs, manufactures and installs electrical bus duct systems for the power
generation industry. A bus duct consists of insulated power conductors housed in
a metal enclosure. Individual pieces of bus duct are arranged in a variety of
physical configurations that may be required to distribute electrical power to
or from a generator, transformer, switching device or other electrical
apparatus. Bus duct systems that can be provided are non-segregated phase,
segregated phase and isolated phase styles with numerous amperage and voltage
ratings. Atkinson Industries, Inc., was acquired in March 1993 and added to
Aztec's Electrical Products Segment. Atkinson, located in Pittsburg, Kansas,
manufactures factory-fabricated electrical power centers and assemblies for the
industrial and power generation industries. The market for Aztec's Electrical
Products Segment is highly competitive and consists of a few large national
companies, as well as numerous small independents. Competition is based


                                      I-1
<PAGE>
 
primarily on product quality, range of product line, price and service. The
Company believes that it can compete favorably with regard to each of these
factors. Copper, aluminum and steel are the primary raw materials used in this
segment and are readily available. This segment's products are sold through
manufacturers' representatives and its internal sales force. This segment is not
dependent on any single customer or limited number of customers for sales, and
the loss of any single customer would not have a material adverse effect on
consolidated revenues. Backlog of orders was approximately $14,082,000 at
February 28, 1998, $10,315,000 at February 28, 1997, and $7,600,000 at February
29, 1996. All of the year end 1998 backlog will be delivered in the next 18
months. Orders included in the backlog are represented by contracts and purchase
orders that the Company believes to be firm. Historically, no material amount of
orders included in the backlog has been canceled. The Company experiences no
seasonal fluctuations in this segment's business nor does it follow any unusual
practices relating to working capital items such as inventory, rights to return
merchandise, and extended payment terms to customers. Total employment in this
segment is 281 persons.

GALVANIZING SEGMENT
Custom hot-dip galvanizing service is provided for industries handling
fabricated metal products. This process provides corrosion protection of
fabricated steel for extended periods up to 50 years. Galvanizing is a highly
competitive business. Aztec competes with other independent galvanizing
companies, captive galvanizing facilities operated by manufacturers, and
alternate forms of corrosion protection such as paint. Market conditions are,
therefore, highly competitive in pricing. Aztec is limited to some extent in its
galvanizing market to areas within a close proximity of its existing locations,
due to freight cost. Zinc, the principal raw material used in the galvanizing
process, is readily available but has volatile pricing. Aztec has a broad
customer base in galvanizing. No one customer represented as much as 10 percent
of consolidated revenues. The backlog of galvanizing orders generally is nominal
due to the short time requirement involved in the process. The Company
experiences no seasonal fluctuations in this segment's business nor does it
follow any unusual practices relating to working capital items such as
inventory, rights to return merchandise, and extended payment terms to
customers. Total employment in this segment is 294 persons.

OIL FIELD PRODUCTS SEGMENT
Aztec processes and provides oil field tubular products to the extent of
upsetting, threading, testing and heat treating and also manufactures oil field
pup joints. The principal market is the oil industry, with distribution through
supply houses, steel mills and other manufacturers in the metal fittings
industry. This business is highly competitive and price sensitive, with
competition coming from several small oil field tubing processors and supply
houses. This segment is unpredictable due to the volatility of oil and natural
gas prices. The Company closed its Houston Tubing facility in March 1989. The
low level of activity in the Company's screw machine operation prompted the
Company to liquidate this facility in November 1992. Steel is the principal raw
material used in this segment and currently is readily available. Aztec has a
limited customer base in this area, but no one customer represents as much as 10
percent of consolidated revenues. Backlog consisted of approximately $5,854,000
at February 28, 1998, $630,000 at February 28, 1997, and $137,000 at February
29, 1996. Backlog is expected to be filled within the coming fiscal year. The
Company experiences no seasonal fluctuations in this segment's business nor does
it follow any unusual practices relating to working capital items such as
inventory, rights to return merchandise, and extended payment terms to
customers. Total employment in this segment is 104 persons

GENERAL
In fiscal 1998 the Company did not introduce a new product line or a new
industry segment or make public its intentions to introduce a new product or do
business in a new industry segment. The Company has established a $423,000
reserve at the end of fiscal 1998 against receivables for any possible loss of
these receivables.

There are no significant patents, trademarks, licenses, franchises or
concessions. The Company does not have a material portion of business that may
be subject to renegotiations of profits or termination of contracts or
subcontracts at the election of the government. There were no material amounts
spent on research and development activities during the preceding three fiscal
years.


                                      I-2

ENVIRONMENTAL
The Company complies, in all material respects, with the relevant legislation
and regulations affecting its operations and the discharge of waste material.
To date, the Company has not expended any material amounts to comply with such
regulations and management does not currently anticipate that future compliance
will have a material adverse effect on the consolidated financial position or
results of operations of the Company.

FORWARD-LOOKING STATEMENT
This Form 10-K contains forward looking statements.  Such statements are
typically punctuated by words or phrases such as "anticipates," "estimate,"
"should," "may," "management believes," and words or phrases of similar import.
Such statements are subject to certain risks, uncertainties or assumptions.
Should one or more of these risks or uncertainties materialize, or should
underlying assumptions prove incorrect, actual results may vary materially from
those anticipated, estimated or projected.  Factors that could cause or
contribute to such differences could include, but are not limited to, changes in
demand, prices, and raw materials cost, including zinc which is used in the
galvanizing segment; changes in the economic conditions of the various markets
the company serves, including the market price for oil and natural gas; as well
as the other risks detailed herein and in the Company's reports filed with the
Securities and Exchange Commission.

                          LETTER TO OUR SHAREHOLDERS

Aztec Manufacturing Co. recorded record revenues of $75.5 million for its fiscal
year ending February 28, 1998. This compares to the $57.7 million recorded in
the previous fiscal year, which was also a record at the time. Revenues
increased a healthy 30.8 percent. Management anticipates the $75.5 million just
recorded will be broken in the fiscal year ending February 28, 1999. Net income
increased 67 percent to $7.2 million from the previous year's $4.3 million. Net
income was impacted by two occurrences; one positive, one negative, and are
discussed in the operational portion of this report. The positive was a $1.1
million tax benefit primarily due to the exercise of stock options. The negative
was a $.5 million pretax non cash write down of zinc inventory to market price
at year end.

The Oil Field Tubing Segment of Aztec's business was positively impacted by
higher prices for crude oil, as well as higher prices for natural gas which
improved exploration and development activity. Prices for these commodities have
eased near term but we believe this is a temporary phenomenon. We expect another
strong year.

The Electrical Segment of Aztec's business remains strong with improved margins
and backlogs.  We continued to expand this segment with the acquisition of
Drilling Rig Electrical Systems Co. in February of 1998.  We have also started a
building expansion at Atkinson Industries that will double our production
capabilities at this facility.  With deregulation in the public utility industry
and a strong economy, this segment should have another record year. We will
continue to take advantage of expansion opportunities in the Electrical and Oil
Field Segments as they arise.

The Galvanizing Segment was expanded with two major acquisitions during the
year.  In March 1997 Hobson Galvanizing in New Orleans was acquired and in
December 1997 International Galvanizers in Beaumont, Texas was acquired.  This
segment now has ten facilities operating in six different states.

Upon review of the operational portion of this report, you will find that all
three segments of our business showed an appreciable improvement in operating
income for the fiscal year just ended.  These improvements hold much
significance for the future of Aztec and its shareholders, and we hope you will
take the time to learn about them.  Aztec is a far different company than it was
when we began the decade of the nineties.  Management is pleased with the
results attained over the past years, but we are disappointed that the
investment community has not looked more favorably on these results. But that
will pass.

Aztec's primary focus for growth will be in the galvanizing industry. This
industry is consolidating and Aztec is and intends to remain in the forefront of
this accelerating consolidation trend. Aztec is in a strong position to
capitalize on the pending consolidation wave and should emerge as a premier
industry "consolidator" for several reasons: 1) Aztec has a strong and rapidly
growing cash flow. 2) Aztec has a well-developed management team, experienced in
running a multi-plant operation. 3) The Company has a large enough presence in
its regional area to begin to achieve some synergies as it makes acquisitions.
Therefore, Aztec can offer a better price than most of its competitors and still
achieve a superior rate of return on invested capital. 4) Management has a
commitment to pursue acquisitions as a source of future growth for the
galvanizing division. Aztec is not approaching the exercise on an opportunistic
basis, but has made this an integral part of its growth strategy. As we continue
to execute this strategy, the investment community should recognize the
sustainability of our growth and our shareholders will be rewarded accordingly.
Great emphasis will be placed on improving shareholder value in the coming
years.

The board of directors, on February 17, 1998, declared a year-end cash dividend
of 10 cents per share, which was a 67% increase over the previous year's
dividend. This 10 cent dividend was paid March 27, 1998, to shareholders of
record as of March 6, 1998.

Aztec's Annual Meeting is scheduled for 10:00 a.m. Tuesday, July 14, 1998, at
the Petroleum Club, in the Derrick I Room, on the 39th floor of the Continental
Plaza, Fort Worth, Texas. We invite all shareholders to attend.

Thank you for your interest and your support of Aztec. The year ahead should
bring good things for our Company. We will keep you informed.

Sincerely,



L.C. Martin
Chairman of the Board
President and Chief Executive Officer

Aztec operates in three distinct businesses, Electrical Products, Hot Dip
Galvanizing and Oil Field Tubular Products.  Each has distinct growth
characteristics and capital requirements.

Last year in these pages the growth opportunities for each segment were briefly
outlined, a framework for capital reinvestment of the rising cash flow was
discussed, and the specialized returns and/or productivity benchmarks of asset
turnover and pretax return on assets were introduced.

Progress has been made on all fronts.  In the electrical group, Rig-A-Lite grew
sales and operating income by 7%, and maintained operating margins above 25%.
Calvert, despite the uncertainty in the Far East, expanded revenues by more than
40%, operating income by more than 50% and entered the new fiscal year with an
expanding backlog.  Atkinson increased its operating income by 14% and commenced
a two million dollar plant expansion, which should double capacity by fall 1998.
And in late February, Aztec acquired DRESCO (Drilling Rig Electrical Systems
Partnership, Ltd) which offers significant synergies with Rig-A-Lite (they buy,
rig and install products which Rig-A-Lite makes and sells) and whose revenues
should add meaningfully to Aztec's total this year.

The Galvanizing Segment made two acquisitions in fiscal 1998.  Hobson, located
outside of New Orleans, in the beginning of the fiscal year and International
Galvanizers in Beaumont, Texas in December 1997.

And as forecasted last year, the Oil Field Segment turned positive; revenues
more than doubled to $8.5 million and a solid operating profit and cash flow
were achieved.

Clearly, fiscal 1998 was another year of growth and we continued to reinvest in
our businesses.  But is our new investment earning a marginally superior rate of
return and yielding productivity gains to make our growth plan sustainable?
And, most importantly, will shareholders reap the benefits?

There is no optimal level for these measurements and different industries have
different parameters.  Retailers and wholesalers for example would likely show
higher sales per employee, but smaller profits per employee than manufacturing
businesses.  THE TREND OVER MULTIPLE YEARS IS WHAT IS RELEVANT.  Aztec strives
for steady improvement and the charts above indicate that we have had some
success in bringing genuine efficiencies to the acquisitions of recent years.
Obviously, the timing of an acquisition can distort these measurements, but a
radical change up or down in any year is worth a closer examination.  In this
era of corporate restructuring, we have seen companies fall victim to excessive
overhead, but there have also been cases of companies that have become too lean
to exploit the growth opportunities presented.

The graphs below show Aztec's progress in shareholder's return on equity over
the last four years.  To put these returns in context, the accompanying graph
plots Aztec's ROE together with the ROE of the Standard & Poors 500 index.  The
superior rate of return achieved is the major reason we keep our dividend pay-
out at a low level of total earnings.  While we have increased dividends each
year since 1996, we are firmly convinced that reinvesting the majority of
earnings at above market rates of return will best serve our shareholders over
the long term.

ELECTRICAL PRODUCTS

Aztec's Electrical Products Segment is one of the Company's core strengths and
remains the largest generator of revenues.  This segment generated approximately
48% of total revenues and 46% of operating profit.  Sales were up significantly,
while operating margins were down slightly in fiscal 1998.    Revenues advanced
20% to $36.4 million and operating income rose 16% to $6.2 million.  Our
strategy is to enhance our world-class status while continuing to grow our
global customer base, offering them an integrated and innovative, one-stop total
solution to their needs.

Aztec's Electrical Products Segment is now comprised of four operating entities:
Rig-A-Lite Partnership, Ltd., The Calvert Company, Atkinson Industries, Inc. and
DRESCO (Drilling Rig Electrical Systems Partnership, Ltd.), our latest
acquisition at the end of fiscal 1998.

RIG-A-LITE PARTNERSHIP, LTD.-HOUSTON, TEXAS

Rig-A-Lite, a leading manufacturer of hazardous and severe environment lighting
fixtures, experienced another year of record sales and profits.

Of the four primary established market segments for our products, food
processing, commercial/industrial, petrochemical and international,
petrochemical experienced substantial sales gains during fiscal 1998. Benefiting
from the strong energy-related pricing and related drilling and production
activity, Rig-A-Lite took full advantage of the increased drilling rig activity
both on and offshore. The market was mixed between refurbished land rigs, barge
conversions and new rigs for land and offshore drilling. This market should
continue to show strength through the year 2000, despite the recent softness in
oil prices. Natural gas prices have not declined appreciably and the offshore
gulf projects are multi-year, long term projects.

The domestic petrochemical market comprised approximately one-quarter of Rig-A-
Lite's sales. Products for this market are normally sold through specialized
petrochemical distributors, but are also sold directly to large end users. In
this market, Rig-A-Lite enjoys the advantage of having its products known by
name as the "best in the business." The major customers in this market are those
involved with domestic exploration and/or production of oil and gas.
Furthermore, the vast majority of Rig-A-Lite's customer base in this market is
located in the South Central states, such as Texas, Louisiana, and Mississippi,
where most domestic exploration takes place.

The recent decline in crude oil prices has raised concerns that drilling
activity will decline precipitously. There has been some moderation in onshore
drilling in recent months, but several trends are becoming evident, which augur
well for demand of Rig-A-Lite product in this arena.

First, because there has been a prolonged drought in new construction of
drilling rigs, onshore and offshore, capital investment in this area has
accelerated substantially in recent years. Secondly, new technology has come to
the oil patch. As a result not only has new construction of rigs, barges,
support boats, offshore platforms, etc. revived, but refurbishment and updating
of the existing equipment stock has also accelerated (see discussion of DRESCO
below).

                              REVIEW OF OPERATIONS

The food processing fixture market, primarily fresh poultry and red meat
products, a market pioneered by Rig-A-Lite, has shifted to new construction
projects. Sales opportunities into other food groups as well as secondary
processors expanded growth potential within this sector, which contributed to
sales growth in the last half of fiscal 1998. This trend should continue into
fiscal 1999. A new generation, state-of-the art, energy efficient product was
developed during the fourth quarter which has great potential to replace
existing R-A-L's 3-5 year old, first generation, food processing fixture. The
marketing success of this new fixture should build during fiscal 1999,
especially with the larger energy conservative end users.

Over half of Rig-A-Lite sales are found within the commercial/industrial and
international markets. Aggressive proactive sales programs were developed during
the year, which provided increased sales growth during the second half of the
year. These programs, which included an intensive field training program, new
product development and increased agent involvement, should continue to gain
momentum into the new fiscal year.

The international market for R-A-L consists of not only the petrochemical sector
but also food and commercial projects as well. With the advent of lower crude
oil prices and political and economic unrest, sales have been inconsistent and
difficult to close. The first half of the new fiscal year should see this trend
turn more positive. In an effort to increase and diversify R-A-L's market
presence, new relationships are being developed within the international
commercial and food processing end user accounts. This proactive market approach
will be augmented with new product, designed around international
specifications, as well as application for ISO-9000 certification.

Late in the fiscal year, Rig-A-Lite involved the parent company in an
acquisition allowing Rig-A-Lite to reenter the drilling rig electrical service
business. Drilling Rig Electrical System Partnership, Ltd. or DRESCO was formed
in January 1977 for the purpose of designing and installing electrical systems
on drilling rigs. Over the years, DRESCO has established itself as a leader of
quality design, workmanship and service. These qualities are very consistent
with the market perception of Rig-A-Lite products and service. The combination
of Rig-A-Lite and DRESCO should provide expanded market capabilities with
synergy of organization, capital and aggressive marketing to provide strong
sales growth for the 1999 fiscal year.

THE CALVERT COMPANY  RICHLAND, MISSISSIPPI

The Calvert Company is a leading manufacturer of custom design electrical
distribution systems in the fields of isolated phase bus, segregated and non-
segregated phase bus, cable bus, and grounding cubicles, plus installation
services.

Calvert experienced vigorous growth, with sales up 43% and profits up 52%. The
major growth came in two product areas. Our segregated and non-segregated bar
bus systems increased by 35% and our isolated phase bus systems grew by 181%
over the previous year. We are expecting good growth, especially with our
isolated phase bus product line and with our new product design of the generator
termination cubicle. We have also refocused our efforts in the installation and
service area and are experiencing growth in this area as well.

Calvert operates in three primary global markets: OEM (original equipment
manufacturers), engineering design firms, and the utility markets.  In general,
Calvert's customer base is with U.S. companies.  This past year nearly 80% of
all our projects were shipped overseas.  Despite this dependence on foreign
sales, Calvert has no currency exposure since we are dealing primarily with U.S.
companies and quote in U.S. dollars.

Calvert's customers continue to be the major worldwide engineering design firms,
power generation manufacturers, investor owned electric utilities, independent
power producers and industrial companies.

With the still uncertain future of the U.S. domestic market due to deregulation
of the electric utility industry, domestic sales will likely continue to be
limited to a replacement market.

Therefore, our focus now is to grow our international presence. We are doing
this two ways: Strategic partnering and by strengthening our direct
international sales representation. Our efforts in Asia Pacific are now
beginning to pay dividends. We are now also focusing our attention in Latin
America. Both regions have vast business opportunities that will help our
international growth strategy. Despite the financial set backs experienced
recently by several countries in Northeast and Southeast Asia, we see a recovery
in progress. Our only direct impact was the delay of several projects, which we
were able to replace from our strong backlog with no adverse impact.

We are monitoring the emerging trends of the deregulated U.S. electric utility
industry and devoting the required resources to capitalize on it. Efforts by the
utilities to downsize their support staff in a cost cutting environment, as a
result of deregulation, have resulted in an increase in outsourcing many of
their internal maintenance and repair projects. Calvert's Installation Services
(CIS) unit has been expanded to meet this rising demand. Our CIS group is
providing bus duct replacement installation, bus maintenance, and installation
supervision of bus duct systems. This trend by the U.S. utilities is an
important factor in our growth plan.

The fiscal year 1998 ended with a strong backlog. Prospects are good for the
coming fiscal year and into the next millennium. Our reputation worldwide is
continuing to grow and with our growth strategy we see a bright future for The
Calvert Company.

ATKINSON INDUSTRIES - PITTSBURG, KANSAS

Atkinsons' primary line of business is the manufacture and selling of custom
engineered factory fabricated modular enclosures. The concept of factory
fabricated modular enclosures was developed in the 1960's to provide
environmentally controlled protection for power distribution equipment in
hazardous areas, primarily refineries. Due to pioneering efforts of Atkinson and
others in the industry, acceptance of the factory fabricated modular enclosure
has been transported across a wider range of industries including petroleum,
chemical, paper, automotive, steel, telecommunications, as well as general
industrials, utilities, and municipalities.

Recent years have shown greater opportunities for Atkinson type enclosures as
the previously mentioned greater acceptance has led to applications beyond the
original power distribution concept. Enclosures are now used to house
instrumentation, analyzing equipment, programmable logic controllers, and
numerous other applications involving microprocessor based equipment. In
addition to the environmental protection of equipment provided by the enclosure,
the Atkinson "turnkey" package reduces user purchasing and coordinating efforts,
as well as reducing project leadtimes. The Atkinson package provides all of
these benefits at a lower cost to the end user.

Fiscal 1998 was an excellent year for Atkinson as the business grew by 18% over
the previous year with improved orders, sales, and operating margins. Several
alliances were developed during the year that should result in positive business
flow in the years to come. Atkinson's network of manufacturer representatives
was solidified and strengthened to provide better and wider market coverage.
Ground was broken on January 29, 1998, for a major expansion at the Pittsburg,
Kansas facility. The expansion will increase Atkinson's capacity and
capabilities needed to keep pace with increased market presence and the
escalating acceptance of the factory fabricated modular enclosure concept.

Fiscal year 1999 beginning backlog was up 27% from the previous year and 58%
ahead of two years ago. Prospects are bright for fiscal 1999 and into the future
as Atkinson capitalizes on the growing acceptance of factory fabricated modular
enclosures across broader applications and geographic markets.

GALVANIZING

Fiscal 1998 saw continuing sales and operating momentum in the Galvanizing
Segment of Aztec. Fueled by two acquisitions, Hobson Galvanizing, Inc. located
outside New Orleans in March and International Galvanizers, Inc. in Beaumont,
Texas in December, sales increased 29% and operating income rose 10%. Of
significance was that these results were achieved against the backdrop of the
greatest volatility of zinc prices in a decade, which necessitated a downward
inventory adjustment of $482,000 at year end.

Aztec Manufacturing now operates ten galvanizing plants. Due to the geographic
restrictions (primarily freight) of the business, each of the plants serves a
different customer base. Galvanizers generally service the steel fabricators in
their area. Most of the customer base is located within a 150 mile radius of the
plant and Aztec plants compete with respective galvanizing facilities contiguous
to their area.

According to the American Galvanizers Association, in 1997, U.S. steel companies
produced 94.9 million tons of steel. Of that, only 2.88 million tons were hot
dip galvanized, about 3%. The significant factor here is that 2.88 million tons
represents a 9.5% increase over the prior years 2.63 million tons. For 1998, the
American Galvanizers Association has projected a 5% increase in tonnage
available to 99.7 tons.

Industry growth trends are not necessarily meaningful because of the regional
nature of the business. Galvanizing is a regional business mainly because
freight quickly becomes a significant cost factor in the pricing equation.

The hot dip galvanizing industry typically serves fabricators and/or
manufacturers involved in the highway, power generation, transportation, water
treatment, agriculture, petrochemical and chemical, pulp and paper and various
types of OEM industries. To maintain its higher margins, Aztec typically pursues
the custom miscellaneous fabrication industries rather than the lower priced
large structural market. Product such as bleacher stands, boat trailers, awning
supports, and elevator components fall into this category. The communication
industry is burgeoning and many of our plants are involved in processing towers
for the cellular industry. Highway products such as light poles and sign
structures represent a large portion of material processed.

Aztec operates plants throughout the South and Southeast and the above average
industry growth rate exhibited by the Company's Galvanizing Segment has clearly
benefited by the overall healthy economic progress of the geographical areas in
which it operates.

Because of the regional nature of the business, the galvanizing industry is
highly fragmented with over 125 job shop type galvanizing plants in the United
States. Even though Aztec processed 95,000 tons of steel in the most recent
year, up 14% from the 83,000 tons in fiscal 1997, that still represents only
slightly more than 3% of industry shipments.

In fiscal 1999, Aztec plans further growth investments. A new kettle will be
installed in the Company's Crowley, Texas plant and also a new and larger kettle
will be installed in the New Orleans plant. Aztec is forecasting increased
output this year of 13% to more than 107,000 tons. In addition, your management
remains ever vigilant and proactive in pursuing acquisition opportunities in
this growing and consolidating industry.

OIL FIELD PRODUCTS

In the early eighties, Aztec was the largest independent processor of oil field
tubing in the United States. After the boom and subsequent bust a decade ago,
the Oil Field Segment has been a very minor part of operations, breaking even or
losing money in the past few years. But as of two years ago, Aztec decided to
make a major business strategy change and began the process of offering finished
tubes.

Fiscal 1998 is the first full year Aztec has offered finished tubing into the
market place. The results for fiscal 1998 are extremely encouraging with revenue
increases of 127% over 1997, as well as showing an operating income versus a
loss in 1997.

Up to the fourth quarter of fiscal 1997, Aztec was a processor of oil well
tubing. As a processor, Aztec would upset, thread and test tubing produced by a
steel mill for the mill or for a third party. At its peak, revenues from the
business exceeded $50 million annually. The industry collapsed in 1986 and Aztec
collapsed with it. Over the course of the following eleven years a major
restructuring of how tubing is marketed has taken place. The steel mills that
remained in the tubing business have brought the processing in-house,
eliminating the need for third party processors. Aztec has now taken the steps
needed to offer the pipe to customers complete. Aztec purchases tubing from
steel mills, processes the tubes and sells the finished product. This approach
has put Aztec's products in the position to compete on the open market with the
best tubes offered in the world.

Calendar 1997 was a good year for oil and gas exploration due to strong oil and
gas prices and advances in technology that have improved economics in marginal
fields. This has been a good springboard in establishing our position in the
market. Although 1997 was a growth year for most oil and gas companies, Aztec's
growth came from strong demand and our success at taking market share from our
competitors.

While revenues more than doubled in tubing products, sales were limited most of
the year by sporadic supplies of new tube. Because of tight industry supplies
and strong demand, Aztec was forced to rely primarily on offshore sources of new
tubes. During the year Aztec purchased raw supplies from Spain, Romania and
Russia among others to fill our requirements. Unfortunately this often meant
that deliveries were sporadic and not timely. In other words even though sales
doubled in the fiscal year, we could have sold more if material had been
available.

With the recent decline in oil prices, there is much uncertainty and concern as
to whether demand and pricing in this marketplace will be healthy in the current
fiscal year. Although oil prices have fallen dramatically in late calendar 1998,
gas prices have remained strong and this should allow a receptive business
atmosphere for us to continue to claim market share. For this reason, Aztec
believes our market share should increase, allowing us a healthy increase in
revenue and income for the coming year. The growth pattern that helped us
achieve our objectives in fiscal 1998 has not shown any signs of slowing through
April 1998. Drilling rig activity remains robust, with rigs in service averaging
850 to 900 monthly through the first quarter of calendar 1998.

It is important to put Aztec's tubing operation in an industry prospective.
Aztec only produced 8,740 tons in fiscal 1998 out of a total industry production
in calendar 1997 of approximately 2.5 million tons, less than 0.3% of total
industry shipments.

                              REVIEW OF OPERATIONS

After the industry bust of 1985-86, most steel companies abandoned the
production of tubular products altogether, or at the very least the small
diameter (under two inches, referred to in the industry as macaroni tubing) part
of the business. Those that remain have concentrated on large diameter tubing
and casing products. Gas wells use the smaller diameter tubing which is Aztec's
forte, and gas well drilling and rework activity remains vibrant.

Aztec management is budgeting a meaningful increase in revenue and tonnage in
oil field tubular goods in fiscal 1999. We have the capacity in place and can do
so with only minimal additional investment in inventory of new tubes. The
potential return is outstanding, given the low depreciated cost basis in our
plant and equipment as well as the incremental free cash flow contributions
which helps fund our continuing acquisition strategy in our galvanizing segment.
The point to be made here is that if we double, triple or even quadruple our oil
field tubular revenues, we would still probably be less than 1% of industry
shipments.

          MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                           AND RESULTS OF OPERATIONS
                                        
GENERAL

Aztec Manufacturing Co. (the "Company") focuses on three industrial markets:
Electrical Products, Galvanizing, and Oil Field Services.  The Company reported
sales of $75.5 million for fiscal 1998 compared with $57.7 million in the
previous year.  Net income for fiscal 1998 was $7.2 million or $1.19 per share
compared with $4.3 million or 74 cents per share on a diluted basis.  Fiscal
1998 earnings included a tax benefit in the amount of approximately $1.1 million
or 18 cents per share, primarily related to the exercise of stock options.  A
discussion concerning effects of new accounting standards can be found in Note 1
of Notes to Consolidated Financial Statements.


RESULTS OF OPERATIONS

YEAR ENDED FEBRUARY 28, 1998 (1998) COMPARED WITH YEAR ENDED FEBRUARY 28, 1997
(1997)

Consolidated net sales for 1998 grew by $17.8 million or 31% over 1997.

Revenues from the Company's Electrical Products Segment, which is made up of 
Rig-A-Lite Partnership, Ltd. ("Rig-A-Lite"), The Calvert Company ("Calvert"),
Atkinson Industries, Inc. ("Atkinson") and Drilling Rig Electrical Systems
Partnership, Ltd. ("DRESCO") were up $6.1 million or 20% for 1998 as compared to
1997. Total backlog in the Electrical Segment was $14.1 million at the end of
fiscal 1998 compared to $10.3 million in 1997. Rig-A-Lite's revenues were up 7%
for 1998. Rig-A-Lite's revenue increase was a direct result of an improved
petroleum industry. Calvert's revenues were up 43% for 1998 compared to 1997,
due to continued market penetration in international markets which represents
80% of Calvert's revenues and Calvert's domestic customer installation service
business was up 11% for the year. Revenues at Atkinson were up 18% for 1998 as
compared to 1997. Sales of Atkinson's factory fabricated power centers, which
represented 91% of Atkinson's revenues, were up 24% over 1997. DRESCO, acquired
on February 23, 1998, designs and installs electrical systems on drilling rigs.
DRESCO, which did not contribute to fiscal 1998 revenues, is expected to make a
significant contribution in fiscal 1999.

Revenues in the Galvanizing Segment were up $6.1 million or 29% for 1998 as
compared to 1997, due to a 3% increase in revenues at the Company's existing
eight facilities and two acquisitions during fiscal 1998.  Hobson Galvanizing
acquired in March 1997 and International Galvanizers acquired in December 1997
contributed a combined total of $6.3 million in revenues or 21% of the segment's
revenues for fiscal 1998.

The Oil Field Products Segment generated 11% of the Company's consolidated
revenues for 1998. Revenues generated from this segment were up $4.8 million or
127% for 1998 from 1997. Total backlog increased to $5.9 million at the end of
fiscal 1998 compared to $630,000 in 1997. The increased revenues in 1998 were a
direct result of Aztec's strategy to become a direct supplier of oil field
tubular goods in fiscal 1997. The Company is continuing its search to find a
long term reliable source of plain end tubing which will improve future
inventory turnover.

Consolidated operating income (see note 10 of notes to consolidated financial
statements) increased $2.3 million or 20% for fiscal 1998, as compared to 1997.

Operating income in the Electrical Segment was up 16% in fiscal 1998 compared to
1997.  Rig-A-Lite's operating income for 1998 was up 7% from 1997, which
corresponded with the increase in revenues for the year.  Calvert's operating
income was up 52% for 1998 compared to 1997, due to increased volumes as well as
higher margin jobs.  Atkinson's operating income was up 14% compared to 1997
from improved margins.

The Galvanizing Segment's total operating income increased 10% during 1998
compared to 1997.  Income in this segment was negatively impacted by a write-
down of zinc inventory to market price in the amount of $482,000 at the end of

segment's eight existing facilities was down 5% due to a 7% reduction in the
volume of steel processed in 1998. Hobson Galvanizing and International
Galvanizers, which were acquired in 1997, contributed 14% of the Galvanizing
Segment's operating income or $936,000 in combined income.

The Oil Field Products Segment showed a $724,000 operating income for 1998 as
compared to the $56,000 loss in 1997. The operating loss in 1997 included
carrying cost of $115,000 for the segment's idle facility in Houston, which was
sold in 1997. The improvement in operating income in this segment is
attributable to the increased volumes of tubular goods processed and sold during
1998.

General corporate expenses for 1998 increased by 13% over 1997 due to higher
employee benefits and profit sharing expenses, and increased selling expenses.
The increased expenses are attributed to higher consolidated sales volumes and
the galvanizing segment acquisitions.

Interest expense in 1998, as compared to 1997, was down due to a lower average
outstanding loan balance through the course of the year.

Other (income) expense was made up of scrap sales, (gains) and losses on sales
of property and equipment, and other (income) expense items not specifically
identifiable to a segment.  This amount included the reduction in various
corporate reserves during 1998 that were no longer needed.


YEAR ENDED FEBRUARY 28, 1997 (1997) COMPARED WITH YEAR ENDED FEBRUARY 29, 1996
(1996)

Consolidated net sales for 1997 grew by $8.5 million or 17% over 1996.

Revenues from the Company's Electrical Products Segment, which is made up of
Rig-A-Lite Partnership, Ltd. ("Rig-A-Lite"), The Calvert Company ("Calvert") and
Atkinson Industries, Inc. ("Atkinson") remained constant for 1997 as compared to
1996.  Rig-A-Lite's revenues were up 18% for 1997.  The increased revenues were
generated primarily from the international and petroleum markets.  Calvert's
revenues were down 20% for 1997 compared to 1996 due to the continued
sluggishness of the domestic power generation market.  Overseas shipments of bus
duct products represented approximately 85% of Calvert's revenues for 1997.
Calvert's domestic customer installation service business, which represented 15%
of Calvert's 1997 revenues, was flat for 1997 as compared to 1996.  Revenues at
Atkinson were up 2% for 1997 as compared to 1996.  Sales of Atkinson's factory
fabricated power centers, which represented 87% of Atkinson's business, were up
3% over 1996.

Revenues in the Galvanizing Segment were up 40% for 1997 as compared to 1996 due
to a 13% increase in revenues at Aztec's existing seven facilities and the
acquisition of Arkansas Galvanizing on February 1, 1996. During the first full
year under Aztec's management, Arkansas Galvanizing represented 21% of total
revenues for this segment.

The Oil Field Products Segment generated 7% of the Company's consolidated
revenues for 1997. Revenues generated from this segment were up 81% for 1997 as
compared to 1996.  The improvement in 1997 compared to 1996 was a direct result
of Aztec becoming a direct provider of finished oil field tubular goods versus
being a third party service company to steel mills in prior years.

Consolidated operating income (see note 10 of Notes to Consolidated Financial
Statements) increased $3.1 million or 38% for 1997, as compared to 1996.

The Electrical Products Segment improved for 1997, with operating income up 25%
over 1996.  Rig-A-Lite's operating income for 1997 was up 45% from 1996 due to
improved margins achieved by cost efficiencies and lower material cost related
to increased volumes.  Calvert's operating income was up 64% for 1997 compared
to 1996.  Continued cost controls and increased efficiencies helped to
improve

margins.  Atkinson's operating income was down 16% for 1997 compared to 1996 due
to less profitable jobs being accepted to improve backlog.

The Galvanizing Segment's operating income increased 39% during 1997 compared to
1996.  Operating income was up 7% due to increased volumes of steel being
processed at Aztec's seven existing facilities and the acquisition of Arkansas
Galvanizing on February 1, 1996.  Arkansas Galvanizing accounted for 24% of this
segment's operating income.

The Oil Field Products Segment showed a $56,000 operating loss for 1997 as
compared to a $428,000 operating loss in 1996.  The operating loss included
carrying costs of the Segment's idle facility in Houston, Texas of $115,000 for
1997 and $139,000 for 1996.  A portion of this facility was sold on October 31,
1996.  The Crowley facility showed a $60,000 operating profit for 1997 as
compared to a $289,000 operating loss in 1996.  The improvement in operating
income at the Crowley facility is attributable to the increased volumes of
tubular goods processed and sold during the last quarter of 1997.

General corporate expenses for 1997 increased by 16% over 1996.  This increase
was attributed to higher employee benefits and profit sharing expenses, and
increased selling expenses.

Interest expense in 1997, as compared to 1996, was down due to lower interest
rates through the course of the year as well as a lower outstanding loan
balance.

Other (income) expense was made up of scrap sales, (gains) and losses on sales
of property and equipment, and other (income) expense items not specifically
identifiable to a segment.  This expense included the establishment of a
corporate reserve for slow moving inventory in the amount of $240,000.


LIQUIDITY AND CAPITAL RESOURCES

The primary sources for the Company's liquidity and capital resources are cash
flow from operating activities, bank debt, and proceeds from the exercise of
stock options. The Company's cash requirements are generally for operating
activities, acquisitions, debt repayment and dividend pay-outs. The Company
believes that working capital, borrowing capabilities, and the funds generated
from operations should be sufficient to finance anticipated operational
requirements, internal growth, and possible future acquisitions.

The Company's operating activities generated cash flow of approximately $2.7
million, $6.8 million, and $9.1 million during fiscal 1998, 1997, and 1996,
respectively.  Before changes in operating assets and liabilities cash flow from
operations was $10.5 million, $6.7 million, and $6 million during fiscal 1998,
1997, and 1996, respectively.  Operating cash flow was provided by net income,
depreciation and amortization, and other non-cash items.  The decrease in cash
flow from operations in 1998 as compared to 1997 was attributed to a $5 million
increase in inventories to support the Company's Oil Field Segment and increased
accounts receivable to support higher consolidated sales.

The Company made various capital improvements, primarily in the galvanizing
segment, and three acquisitions in 1998 which were funded from cash flow and
bank debt.  Hobson Galvanizing was purchased in March 1997 for approximately
$3.9 million in cash, International Galvanizers, Inc. was purchased in December
1997 for approximately $1.7 million in cash and Drilling Rig Electrical Systems
Partnership, Ltd. was purchased in February 1998 for approximately $1.2 million
in cash.  Other major uses of cash during 1998 included repayment of debt,
payment of cash dividends and purchase of treasury stock.

          MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                           AND RESULTS OF OPERATIONS

The Company maintains a $20 million credit facility, which consists of a $10
million term note and a $10 million revolving line of credit. Current
availability under the revolving line of credit is approximately $4.5 million.


ENVIRONMENTAL MATTERS

In the course of its galvanizing operations, the Company is subject to
occasional governmental proceedings and orders pertaining to noise, air
emissions and water discharges into the environment. As part of its continuing
environmental program, the Company has complied with such proceedings and orders
without any materially adverse effect on its business.

The Company provides for costs related to contingencies when a loss is probable
and the amount is reasonably determinable.  It is the opinion of management,
based on past experience, that the ultimate resolution of these contingencies,
to the extent not previously provided for, will not have a materially adverse
effect on the Company.


YEAR 2000 COMPLIANCE

The Company is in the process of reviewing and making necessary modifications to
its computer systems for year 2000 compliance.  Costs incurred to date to modify
the Company's computer systems have not been material, and future costs are not
expected to be material.  Timely completion of such modifications is not
considered to be a material risk to the Company.  The Company is also
communicating with vendors and others with which it does business to coordinate
Year 2000 compliance.  There can be no assurance that the systems of other
companies and agencies on which the Company relies will be timely converted or
that such failure by other entities would not have an adverse impact on the
Company's operations.

                   NOTES TO CONSOLIDATE FINANCIAL STATEMENTS


1.   Summary of significant accounting policies

     Organization--Aztec Manufacturing Co. (the "Company") operates primarily in
     the United States. Information on the Company's operations by segment are
     included in Note 10 to the consolidated financial statements.

     Basis of consolidation--The consolidated financial statements include the
     accounts of Aztec Manufacturing Co. and its wholly-owned subsidiaries and
     partnerships. All significant intercompany accounts and transactions have
     been eliminated in consolidation.

     Use of estimates--The preparation of the 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. The primary areas of estimation
     affecting the consolidated financial statements include the determination
     of the allowance for doubtful accounts receivable, inventory reserves and
     warranty and environmental accruals. Actual results could differ from those
     estimates and assumptions.

     Concentrations of credit risk--Financial instruments that potentially
     subject the Company to significant concentrations of credit risk consist
     principally of cash, investments and trade accounts receivable.

     The Company maintains cash and cash equivalents with various financial
     institutions. These financial institutions are located throughout the
     country and Company policy is designed to limit exposure to any one
     institution. The Company performs periodic evaluations of the relative
     credit standing of those financial institutions that are considered in the
     Company's banking relationships.

     Concentrations of credit risk with respect to trade accounts receivable are
     limited due to the diversity of operating segments. The Company's net
     credit losses in 1998, 1997 and 1996 were approximately $102,000, $124,000
     and $589,000, respectively. Collateral is usually not required from
     customers as a condition of sale.

     Revenue recognition--The Company recognizes revenue from product sales upon
     shipment.

     Inventories--Inventories are stated at the lower of cost (primarily first-
     in, first-out) or market. Provisions for obsolete and slow-moving
     inventories are recorded.

     Property, plant, and equipment--For financial reporting purposes,
     depreciation is computed by the straight-line method using rates based on
     the estimated useful lives of the related assets as follows:

              Buildings and structures                    10-25 years
              Machinery and equipment                      3-15 years
              Furniture and fixtures                       5-15 years
              Automotive equipment                            3 years

     Cash equivalents--For purposes of reporting cash flows, the Company
     considers all highly liquid debt instruments purchased with an original
     maturity of three months or less to be cash equivalents.

     Intangible assets and costs in excess of fair value of assets purchased--
     Intangible assets include purchased intangibles (customer lists,
     engineering drawings, non-compete agreements, and sales backlog). Such
     intangible assets and costs in excess of fair value of assets purchased are
     being amortized over the estimated useful lives of the assets ranging from
     5 to 40 years.

     Asset impairment--The Financial Accounting Standards Board issued Statement
     of Financial Accounting Standards (SFAS) No. 121, "Accounting for the
     Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed
     Of," in March 1995. SFAS No. 121 requires that long-lived assets and
     certain identifiable intangibles (such as those described above) be
     reviewed for impairment whenever events or changes in circumstances
     indicate the carrying amount of an asset may not be recoverable.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


1.   Summary of significant accounting policies (continued)

     The Statement also requires assets to be disposed of be reported at the
     lower of carrying amount or fair value less costs to sell. The new standard
     is effective for the fiscal years beginning after December 15, 1995. No
     assets were impaired and it is expected that the carrying amount of all
     assets will be recoverable.

     Income taxes--Deferred income taxes are recognized using the liability
     method. Under this method of accounting, deferred income taxes are recorded
     for the difference between the financial reporting and income tax bases of
     assets and liabilities using enacted tax rates and laws.

     Stock-based compensation--The Company grants stock options for a fixed
     number of shares to employees and directors with an exercise price equal to
     the fair value of the shares at the date of grant. The Company accounts for
     stock option grants in accordance with Accounting Principles Board Opinion
     No. 25, "Accounting for Stock Issued to Employees," and accordingly,
     recognizes no compensation expense for the stock option grants in which the
     exercise price is equal to the fair value of the shares granted.

     Earnings per share--Effective February 28, 1998, the Company adopted
     Statement of Financial Accounting Standards (SFAS) No. 128, "Earnings per
     Share," which established new standards for computing and disclosing
     earnings per share. SFAS No. 128 requires dual presentation of "basic" and
     "diluted" earnings per share, each as defined therein, which replaced
     primary and fully diluted earnings per share, respectively, required under
     previous guidance. The new standard had no effect on previously reported
     earnings per share amounts.

     Fair value of financial investments--The following methods and assumptions
     were used by the Company in estimating its fair value disclosures for
     financial instruments as of February 28, 1998:

        Cash and cash equivalents: The carrying amount reported in the
        consolidated balance sheet for cash and cash equivalents approximates
        fair value.

        Long-term investments: The carrying value of long-term investments in
        the consolidated balance sheet approximates fair value.

        Long-term debt: The reported amounts of the Company's long-term debt
        approximate fair value since interest rates for substantially all of the
        debt approximate current rates of interest.

     Reclassification--Certain prior year amounts have been reclassified to
     conform to the 1998 presentation.

2.   Inventories

     Inventories consist of the following:

                                                             1998       1997

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


3.   Long-term investments

     The Company's long-term investments represent investments in tax-free
     municipal bonds maturing in 2001 and carrying interest at rates ranging
     from 5.1% to 5.5%. The investments were purchased and are being held to
     secure the Company's outstanding letters of credit with a bank.

4.   Employee benefit plans

     The Company has a trusteed profit sharing plan covering substantially all
     of its employees. Under the provisions of the plan, the Company contributes
     amounts as authorized by the Board of Directors. Contributions to the
     profit sharing plan amounted to $992,000 for 1998, $715,000 for 1997 and
     $426,000 for 1996.

5.   Income taxes

     Deferred federal and state income taxes reflect the net tax effects of
     temporary differences between the carrying amounts of assets and
     liabilities for financial reporting purposes and the amounts used for
     income tax purposes. Significant components of the Company's net deferred
     income tax liabilities and assets as of February 28, 1998 and 1997 are as
     follows:

                                                         1998         1997

6.   Earnings per share

     Earnings per share is based on the month-end average number of shares
     outstanding during each year, adjusted for the dilutive effect of stock
     options. Cash dividends paid (or declared) per share are $.10 in 1998, $.06
     in 1997 and $.03 in 1996.

     The following table sets forth the computation of basic and diluted
     earnings per share:

     Statement of Financial Accounting Standards (SFAS) No. 123, "Accounting for
     Stock Based Compensation," requires the disclosure of pro forma net income
     and income per share of common stock information computed as if the Company
     had accounted for its stock options granted subsequent to February 28, 1995
     under the fair value method set forth in SFAS 123. The fair value for these
     options was estimated at the date of grant using the Black-Scholes option
     pricing model with the following weighted average assumptions: a risk-free
     interest rate ranging from 5.8% to 6.5% for options granted in 1998 and
     6.5% for options granted in 1997; a dividend yield of 1%; and a volatility
     factor of .498. In addition, the fair value of these options was estimated
     based on an expected life ranging from 1 1/2 years to 5 years.

     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 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 fair value for the
     Company's stock options.

7.   Stock options (continued)

     For purposes of pro forma disclosures, the estimated fair value of the
     options is amortized to expense on a straight-line basis over the option's
     vesting period as adjusted for estimated forfeitures. The pro forma effect
     of the 1997 and 1996 options granted is not material to the operations of
     the Company for 1997 and 1996. The Company's pro forma information for 1998

     The revolving line of credit, term note and industrial revenue bonds are
     subject to loan agreements which require the Company to comply with various
     financial covenants including minimum requirements with regard to working
     capital, debt-to-net worth ratio, dividend payments, capital expenditures
     and cash flows. The Company is in compliance with these covenants as of
     February 28, 1998. The Company's long-term debt is secured by inventory,
     equipment, and fixtures. Pursuant to the loan agreement, the limit of
     borrowings under the revolving line of credit is limited to certain
     percentages of trade accounts receivable and inventory and is reduced by
     the balance of outstanding letters of credit, which amounted to $195,000 at

10.  Operating segments (continued)

     (b) Other (income) expense, net includes gains and losses on sale of
         property, plant, and equipment and other (income) expense not
         specifically identifiable to a segment.

11.  Commitments and contingencies

     The Company is subject to various environmental protection reviews by state
     and federal government agencies and has been identified as a potential
     responsible party in certain investigations conducted by these agencies.
     The Company did not expense any significant amounts related to
     environmental liabilities in 1998, 1997 or 1996. The ultimate liability, if
     any, which might result from such reviews or additional clean-up and
     remediation expenses cannot presently be determined; however, as a result
     of an internal analysis and prior clean-up efforts, management believes the
     results will not have a material impact on the Company and that the
     recorded reserves for estimated losses are adequate.

     In order to maintain permits to operate certain of the Company's
     facilities, future capital expenditures for equipment may be required to
     meet new or existing environmental regulations.

12.  Acquisitions

     In March 1997, the Company purchased substantially all of the assets of
     Hobson Galvanizing for approximately $3.9 million in cash. The assets
     purchased were recorded at estimated fair value; the costs in excess of
     fair value for this acquisition were approximately $2.8 million. In
     connection with this acquisition, the Company paid the selling shareholders
     $250,000 pursuant to an agreement not to compete.

     The Company purchased substantially all of the assets of International
     Galvanizing in December 1997 for approximately $1.7 million in cash. Costs
     in excess of estimated fair value of this acquisition were approximately
     $350,000. Additionally, the Company paid the selling shareholder $50,000
     pursuant to an agreement not to compete.

     In February 1998 the Company purchased substantially all of the assets of
     Drilling Rig Electrical Systems Co. (DRESCO), a company which is involved
     in the selling and installation of oil field lighting, for approximately
     $1.2 million in cash. Costs in excess of estimated fair value of this
     acquisition were approximately $190,000.

     All acquisitions were accounted for under the purchase method of
     accounting. Operations applicable to acquired businesses, which are
     immaterial to the consolidated operations of the Company, are included in
     the accompanying Consolidated Statements of Income from their respective
     dates of acquisition. The excess of costs over fair value for these
     acquisitions is being amortized over a period of 15 years.

     In February 1996, the Company purchased all of the stock of Arkansas
     Galvanizing, Inc. for approximately $4.2 million in cash and the assumption
     of approximately $.8 million in liabilities. Costs in excess of estimated
     fair value of this acquisition were approximately $2.8 million. In
     connection with this acquisition, the Company agreed to pay the selling
     shareholders $450,000 pursuant to an agreement not to compete. The total
     potential obligation will be paid and expensed in equal monthly
     installments over a 60 month period which commenced on April 1, 1996. The
     acquisition was accounted for under the purchase method of accounting. The
     excess of costs over fair value is being amortized over the estimated
     useful life of 25 years.

Board of Directors and Shareholders
Aztec Manufacturing Co.

We have audited the accompanying consolidated balance sheets of Aztec
Manufacturing Co. as of February 28, 1998 and 1997, and the related consolidated
statements of income, shareholders' equity, and cash flows for each of the three
years in the period ended February 28, 1998. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the consolidated financial position of Aztec
Manufacturing Co. at February 28, 1998 and 1997, and the consolidated results of
its operations and its cash flows for each of the three years in the period
ended February 28, 1998, in conformity with generally accepted accounting

                          TO BE HELD ON JULY 14, 1998

This Proxy Statement is furnished in connection with the solicitation of proxies
by the board of directors of Aztec Manufacturing Co. (the "Company") for use at
the regular Annual Meeting of the Shareholders of the Company to be held at the
Petroleum Club in the Derrick I Room on the 39th floor of the Continental Plaza,
777 Main Street, Fort Worth, Texas, on the 14th day of July, 1998, at 10:00
a.m., and at any adjournment or adjournments thereof.  This Proxy Statement and
the accompanying proxy are being mailed on or about June 1, 1998, to the
Shareholders of the Company.

GENERAL INFORMATION
- -------------------

At the close of business on the 25th day of May, 1998, the record date for
determination of shareholders entitled to notice of and to vote at the meeting,
there were outstanding 5,927,413 shares of Common Stock, $1.00 par value, of the
Company (the "Common Stock").  The presence, in person or by proxy, of the
holders of a majority of the outstanding shares of Common Stock is necessary to
constitute a quorum at the meeting.  All shares represented at the meeting in
person or by proxy shall be counted in determining the presence of a quorum.

Each holder of shares of Common Stock will be entitled to one vote, in person or
by proxy, for each share of Common Stock of the Company owned of record at the
close of business on May 25, 1998.  Cumulative voting for directors is not
permitted. Directors are elected by plurality vote and, therefore, the three
nominees receiving the highest number of affirmative votes shall be elected as
directors provided a quorum is present.  Abstentions and broker non-votes will
not be considered part of the voting power present with respect to any matter on
which such shares so acted which has the effect of reducing the number of shares
voting affirmatively that is required to approve a matter requiring a majority
vote.  Therefore, assuming a quorum is present, if more shares vote "for"
approval of the appointment of the independent auditors than vote "against,"
this matter will pass.  All shares of Common Stock represented by a valid proxy
will be voted.  A proxy may be revoked at any time before it is voted by filing
with the Secretary of the Company a written revocation thereof or a duly
executed proxy bearing a later date.

The cost of preparing, assembling and mailing the Notice of Annual Meeting of
Shareholders, the Proxy Statement and the accompanying proxy will be borne by
the Company.  In addition to solicitation of proxies by mail, certain officers
and employees of the Company, without additional compensation for such services,
may solicit proxies by telephone, fax or personal contact.  The Company will
also supply brokerage firms and other custodians, nominees, and fiduciaries with
such number of proxy materials as they may require for mailing to beneficial
owners and will reimburse them for their reasonable expenses in connection
therewith.

PROPOSAL NO. 1:  ELECTION OF DIRECTORS
- --------------------------------------

The Bylaws of the Company provide for nine directors and classify the Board of
Directors into three classes, each class consisting of three directors, the
members of which serve for three years.  Of the directors listed under
"DIRECTORS OF THE COMPANY," the terms of office of L. C. Martin, R.J.
Schumacher, and Dr. H. Kirk Downey expire at the 1998 Annual Meeting of
Shareholders.  The Board of Directors nominated and recommends the reelection of
Messrs. L. C. Martin, R.J. Schumacher, and Dr. H. Kirk Downey  for a three-year
term expiring at the 2001 Annual Meeting of Shareholders.

Mr. John G. Richards retired as a director of the Company on Nov. 13, 1997.  Mr.
Richards is now an advisory director of the Company.  As an advisory director,
Mr. Richards does not have voting authority.  The Bylaws of the Company provide
that any vacancy in the Board is to be filled by the remaining directors with
the newly elected director serving the unexpired term of his predecessor.  Mr.
Richards term would have expired in 1999.  The Board of Directors of the Company
elected at its Nov. 13, 1997,  meeting Mr. Kevern R. Joyce to fill the unexpired
term of Mr. Richards.

All of the nominees are now directors of the Company.  All of the nominees have
consented to serve if elected.  If for any unforeseen reason a nominee would be
unable to serve if elected, the persons named in the accompanying proxy may
exercise their discretion to vote for a substitute nominee selected by the Board
of Directors.  However, the Board of Directors has no reason to anticipate that
any of the nominees will not be able to serve, if elected.

The Board of Directors recommends that Shareholders vote "FOR" the election of
                          the nominees for directors.

COMPLIANCE WITH SECTION 16(a) OF THE SECURITIES EXCHANGE ACT OF 1934.  Section

directors and persons who beneficially own more than ten percent of the
Company's stock to file initial reports of ownership and reports of changes of
ownership with the Securities and Exchange Commission.  Copies of such reports
are required to be furnished to the Company.

Based solely on a review of such forms furnished to the Company and certain
written representations from the executive officers and directors, the Company
believes that all Section 16(a) filing requirements applicable to its executive
officers, directors and greater than 10% beneficial owners were complied with on
a timely basis, except that Mr. Martin Bowen, Director reported a sale of Aztec
stock on Form 5 instead of on a current report on Form 4.

EXECUTIVE COMPENSATION AND OTHER MATTERS
- ----------------------------------------

REPORT OF COMPENSATION COMMITTEE ON EXECUTIVE COMPENSATION.  Through fiscal
periods ended February 28, 1998, compensation for the chief executive officer
and senior executives has been approved by the full Board of Directors upon the
recommendations of the Compensation Committee.  This Committee is composed of
two outside directors, none of whom perform any services to or receive any fees
from the Company in any capacity other than as director.

It has been the philosophy and the practice of the Committee to relate executive
compensation to the profitability of the Company.  The compensation program
provides for market-driven salary ranges based on job responsibilities and
influences on Company performance with a balanced incentive compensation element
based on profit performance of the Company.  This is accomplished through a two-
tiered structure of measuring the compensation rewards as follows:

1.   Base Salary - The Committee reviews and approves salaries for the chief
     executive cfficer and the other executive officers on an annual basis.
     Recommended base salaries are reviewed and set based on information derived
     from comparative group reviews and national surveys of compensation data,
     as well as evaluations of the individual executives' positions and expected
     future performance and contribution. In making salary decisions, the
     Committee exercises its discretion and judgment with no specific formula
     being applied to determine salary levels.

2.   Bonus - The purpose of the bonus program is to promote the Company's goal
     of increasing shareholder value through sustainable internal growth, high
     operating efficiencies, strategic acquisitions, and attracting highly
     motivated, results-oriented executive officers. A portion of executive
     compensation was calculated using a formula reflecting growth in pretax
     income of the Company in the case of the chief executive officer and
     certain executive officers or a particular segment of the Company in the
     case of an executive officer who is responsible for such segment. Mr.
     Martin's and Mr. Perry's bonus base is fixed at 2.5% and 1% of the yearly
     pretax profits of the Company, respectively. Mr. Wright's and Mr. Skowron's
     bonus base is fixed at 1.25% of the yearly pretax profits of the
     Galvanizing Segment and Electrical Segment, respectively. The maximum and
     minimum bonus is set at 150% and 50% of the bonus base, respectively. When
     the Company or a segment exceeds prior year performance, the executives are
     rewarded through increased bonuses up to a maximum of 150% of his bonus
     base. Conversely, if the Company or segment falls short of the prior year's
     performance, the executive officers receive a reduced bonus. If the current
     years performance falls below 50% of the prior year, the executive officers
     receive no bonus.

Additionally, the executive officers participate, along with other employees, in
the Company Profit Sharing Plan, the annual contributions to which are
dramatically affected by profitability of the Company, and the Company Stock
Option Plans.

Section 162(m) of the Internal Revenue Code of 1986, as amended, which was
enacted in 1993, imposes a $1 million limit on the amount of compensation that
will be deductible by the Company with respect to the chief executive officer
and the four other most highly compensated executive officers.  Performance
based compensation that meets certain requirements will not be subject to the
deduction limit.  The Committee has reviewed the impact of Section 162(m) on the
Company and believes it is unlikely that the compensation paid to any executive
officer during the fiscal year ending February 28, 1999, will exceed the limit.
The Committee will continue to monitor the impact of the Section 162(m) limit
and to assess alternatives for avoiding any loss of tax deductions in future
years.

The role of the Compensation Committee also includes a full review of the
compensation package of the five highest paid executive officers, whether or not
their salary and bonuses exceed $100,000.  This review is then presented and
recommended to the full board of nine directors, seven of whom are independent
directors.

CHANGE IN CONTROL AGREEMENT.  The Company has entered into a change in control
agreement with Mr. L. C. Martin, the president and chief executive officer of
the Company.  The change in control agreement provides for the payment of
certain benefits upon the occurrence of a change in control of the Company.  A
"change in control of the Company" includes the acquisition by any person of 50
percent or more of the shares of Common Stock, a merger or consolidation of the
Company in which the Company does not survive as an independent public company,
a sale of all or substantially all of the assets of the Company, or a
liquidation or dissolution of the Company.

Under the change in control agreement, if Mr. Martin remains in the employ of
the Company for a period of at least three months immediately following the date
of occurrence of a change in control of the Company, he will be entitled to
receive a lump sum payment from the Company within five days after the
expiration of the three-month period, regardless of whether he continues in the
employ of the Company after the expiration of the three-month period (the
"Change in Control Payment").  The change in control agreement provides for the
payment of the Change in Control Payment of $750,000 in the event of any change
in control of the Company, whether or not such change in control is approved by
the Board of Directors and/or Shareholders of the Company.  Additionally, if
during the three-month period Mr. Martin is terminated as a result of death or
total disability or for any other reason whatsoever by the Company, he will be
entitled to receive, in addition to the Change in Control Payment provided
above, his full base salary through the date of termination of his employment,
plus any other amounts to which he would be entitled under any compensation plan
of the Company.  However, if the employment of Mr. Martin  during the three-
month period is terminated by him for any reason other than as a result of his
death or total disability or voluntary termination for good reason as defined in
the agreement, he would be entitled to his full base salary through the date of
termination of his employment, plus any other amounts to which he would be
entitled under any compensation plan of the Company, but would not be entitled
to the Change in Control Payment provided above.

BUY-SELL AND TERMINATION AGREEMENT.  During fiscal 1994 the Company entered into
a "Buy-Sell and Termination Agreement" (the "Agreement") with Mr. L. C. Martin,
the president and chief executive officer of the Company.  The Agreement
provides that the proceeds from a $1 million dollar life insurance policy on Mr.
Martin be used to acquire (from the executive's wife or estate) the number of
shares of Company Common Stock which could be purchased in the event the
executive dies while employed by the Company.  The purchase price per share is
to be the market value of the stock on the day before the date of death.  Upon
termination (other than for "just cause") of employment from the Company prior
to death, the Company will convey all rights in the insurance policy to the
executive, including cash surrender value.  The Company recorded a deferred
liability and corresponding charge to expense in the amount of $246,000 during
fiscal 1994. The deferred compensation amount is equivalent to the cash
surrender value of the insurance policy and amounted to $276,730 at February 28,
1998.

Under the "Buy-Sell and Termination Agreement", the Company agrees to maintain a
whole life insurance policy in the face amount of $1 million on the life of Mr.
Martin previously acquired by the Company (the "Policy").  The Company shall be
the owner and direct beneficiary of the Policy and shall be solely responsible
for the payment of any and all premiums required to be paid to keep the Policy
in effect.  Within 180 days of the death of Mr. Martin, if Mr. Martin was at 

                                      -7-

<PAGE>
 
the time of his death employed by the Company, Mrs. Martin or the estate, heirs,
legal representatives, successors or beneficiaries of Mr. Martin shall tender to
the Company for sale, transfer or conveyance to the Company a number of shares
equal in value to the proceeds received by the Company from the Policy. Upon the
tender of the shares of the Company, the Company shall purchase the shares with
the proceeds received by the Company under the policy. For purposes of this
Agreement, the value of the shares to be sold, assigned and conveyed to the
Company as provided for herein shall be determined based on the closing price
per share of the Common Stock of the Company as traded on the New York Stock
Exchange on the day before the date of death of Mr. Martin. Upon the termination
of employment of Mr. Martin from the Company for any reason other than "Just
Causes", the Company hereby agrees to assign and convey all rights and title of
the Company in the Policy, including any cash surrender value in the Policy, to
Mr. Martin. No shares shall be transferred to the Company in consideration of
the assignment and conveyance of the Policy to Mr. Martin. For purposes of this
Agreement, "Just Cause" shall mean Mr. Martin willfully and intentionally fails
to substantially perform his duties as an officer of the Company, or Mr. Martin
has committed an illegal act (other than minor traffic violations or similar
acts) in connection with his employment that could reasonably be expected to
materially adversely affect the Company. If Mr. Martin is terminated for "Just
Cause," the Company shall be under no obligation to assign and convey the Policy
to Mr. Martin.

PROPOSAL NO. 3: 1998 INCENTIVE STOCK OPTION PLAN
- ------------------------------------------------

On April 21, 1998, the board of directors of the Company adopted, subject to the
approval of the shareholders of the Company, the 1998 Incentive Stock Option
Plan of Aztec Manufacturing Co.  (the "1998 ISO Plan"). Options granted under
the 1998 ISO Plan are intended to qualify as "incentive stock options" under
Section 422 of the Internal Revenue Code of 1986, as amended, (the "Code").

A summary of the material provisions of the 1998 ISO Plan is set out below.  The
following summary is qualified in its entirety by reference to the full text of
the 1998 ISO Plan, a copy of which is attached as Exhibit A to this Proxy
Statement.

The purpose of the 1998 ISO Plan is to attract capable employees and provide an
incentive for employees to remain in the employ of the Company and its
subsidiaries.  All executives and other key personnel of the Company who are
active full time salaried employees of the Company and its subsidiaries are
eligible to participate in the 1998 ISO Plan.  Members of the board of directors
who are not employed by the Company or its subsidiaries on a full time basis are
not eligible to participate in the 1998 ISO Plan.  Approximately 150 persons
will be eligible to participate in the 1998 ISO Plan.

The 1998 ISO Plan is administered by the Compensation Committee, a committee
composed of at least two (2) non-employee directors of the board of directors of
the Company (the "Committee").  The Committee has discretion to select the
eligible employees to whom options shall be granted under the 1998 ISO Plan and
to determine the number of shares of Common Stock subject to options granted
under the 1998 ISO plan, as well as the term during which such options may be
exercised and the manner of exercise thereof.

Subject to provisions for proportionate adjustment occasioned by changes in the
Company's capital structure, a total of 750,000 shares of Common Stock of the
Company has been set aside under the 1998 ISO Plan for use upon exercise of
options granted thereunder.  As of the date hereof, no options to purchase
Common Stock have been granted by the Committee under the 1998 ISO Plan.  All
options under the 1998 ISO Plan must be granted on or before ten years from the
effective date of the 1998 ISO Plan.  The 1998 ISO Plan will be effective upon
shareholder approval.

No options may be exercised under the 1998 ISO Plan without compliance with
applicable securities laws.  It is contemplated by management of the Company
that the options and the shares of Common Stock called for by options granted
under the 1998 ISO Plan will be registered by the Company under the federal
securities laws during the latter half of 1998.

The maximum term of an option that may be granted under the 1998 ISO Plan is ten
(10) years, except that with respect to participants, if any, under the 1998 ISO
Plan who own more than ten percent (10%) of the Common Stock of the Company on
the date the option is granted,  the maximum term is five (5) years.

The price at which shares of Common Stock of the Company may be purchased
pursuant to the exercise of options granted under the 1998 ISO Plan shall not be
less than one hundred percent (100%) of the fair market value of the shares of
Common  Stock underlying the options on the date such options are granted.  With
respect to participants, if any, under the 1998 ISO Plan who own more than ten
percent (10%) of the shares of Common Stock of the Company on the date the
option is granted,  the price at which shares of Common Stock of the Company may
be purchased pursuant to the exercise of options granted under the 1998 ISO Plan
shall not be less that one hundred ten percent (110%) of the fair market value
of the shares of Common Stock underlying the options on the date such options
are granted.

The aggregate fair market value (determined at the time of grant) of shares of
Common Stock underlying incentive stock options exercisable for the first time
by an employee during any calendar year cannot exceed $100,000.

Options granted under the 1998 ISO Plan are subject to earlier termination upon
the death, disability, retirement or termination of employment of the
participant.  Options granted under the 1998 ISO Plan are exercisable over such
period of time as may be determined by the Committee.  Such options are not
transferable, except by will or by the laws of descent and distribution and may
only be exercised for a period of one year following the date of death or
disability, to the extent the options were exercisable at the date of death or
disability, as the case may be.  A participant must remain an employee of the
Company as a condition to his right to exercise options granted under the 1998
ISO Plan.  However, upon a participant's termination of employment for any
reason, other than gross or willful misconduct or death or disability, such
participant has a right to exercise an option granted to such participant under
the 1998 ISO Plan during the three month period immediately following the date
of termination of employment.

The following is a summary of the principal U.S. federal income tax consequences
under current federal income tax laws relating to awards under to the 1998 ISO
Plan.  This summary is not intended to be exhaustive and, among other things,
does not describe state, local or foreign tax consequences.  Participants are
urged to consult their own tax advisors as to the precise tax consequences of
participation in such plan.  Under applicable provisions of the Code as now in
effect: (a) an "incentive stock option" results in no taxable income to
participant or deduction to the Company at the time it is granted; (b) upon
exercise of the option, no taxable income results to the participant from the
receipt of the shares of Common Stock thereby acquired and no deduction is
allowed to the Company; the exercise of an incentive stock option will result in
an adjustment in determining a participant's alternative minimum tax; (c) if,
after exercise of such an option, the participant does not dispose of the shares
of Common Stock thereby acquired within two (2) years of the date of grant of
the option or within one (1) year of the date of exercise of the option, he will
be entitled to treat any gain realized upon disposition of the shares of Common
Stock as long-term capital gain in the year of sale; and (d) if so held by the
participant, as described in clause (c) above, the Company will not be entitled
to any deduction on account of the grant or exercise of the option.  However, if
the participant disposes of the shares of Common Stock within two (2) years of
the date of grant of the option or within one (1) year of the date of exercise
of the option, he will be required to treat any gain realized upon disposition
of the shares of Common Stock as ordinary income in the year of sale equal to
the difference between the option price and the fair market value of the stock
on the date of exercise.  The balance of the participant's gain on the
disposition of the shares will be treated as a long-term capital gain, provided
the holding period applicable to long-term capital assets is satisfied.  The
Company will be entitled to a deduction to the extent the participant recognizes
ordinary income.

The affirmative vote of the holders of a majority of the total number of shares
represented and voting at the Shareholder's Meeting, assuming a quorum is
present, is required to approve the adoption of the 1998 Incentive Stock Option
Plan of the Company.

The Board of Directors recommends that Shareholders vote "FOR" the approval of
the 1998 Incentive Stock Option Plan of the Company.

PROPOSAL NO. 4:  1998 NONSTATUTORY STOCK OPTION PLAN
- ----------------------------------------------------

On April 21, 1998, the Board of Directors unanimously adopted, subject to
approval by Shareholders, the 1998 Nonstatutory Stock Option Plan of Aztec
Manufacturing Co. (the "1998 NSO Plan").

A summary of the material provisions of the 1998 NSO Plan is set out below.  The
following summary is qualified in its entirety by reference to the full text of
the 1998 NSO Plan, a copy of which is attached as Exhibit B to this Proxy
Statement.

The purpose of the 1998 NSO Plan is to encourage stock ownership by executive
officers and non-employee directors of the Company, to provide an incentive for
executive officers and non-employee directors to expand and improve the profits
and prosperity of the Company, and to assist the Company in attracting and
retaining executive officers and non-employee directors through the grant of
options to purchase shares of the Company's Common Stock.  Only executive
officers and non-employee directors of the Company are eligible to participate
in the 1998 NSO Plan.

The executive officers of the Company at present are: L.C. Martin, Dana L.
Perry, F.L. Wright, Jr., Richard Skowron and Sam Rosen.  The outside, non-
employee directors at the present are: Robert H. Johnson, R. J. Schumacher, W.C.
Walker, H. Kirk Downey, Kevern Joyce, and Martin C. Bowen.

The 1998 NSO Plan is administered by the Compensation Committee ("Committee"), a
committee composed of at least two (2) non-employee directors of the board of
directors of the Company.

Subject to provisions for proportionate adjustment occasioned by changes in the
Company's capital structure, a total of 250,000 shares of Common Stock of the
Company has been set aside under the 1998 NSO Plan for use upon exercise of
options granted thereunder.  No options to purchase Common Stock have been
granted under the 1998 NSO Plan.

The purchase price for the stock under each option is one-hundred (100%)  of the
fair market value of the Common Stock evidenced by the price at which the Common
Stock closed on the date the option is granted, but in no event less than the
par value of the Common Stock.  The 1998 NSO Plan terminates ten years after its
effective date and no options can be granted under it after that date.  The 1998
NSO Plan will be effective upon Shareholder approval and no options can be
granted under it prior to that approval.

Plan.  This summary is not intended to be exhaustive and, among other things,
does not describe state, local or foreign tax consequences.  Participants are
urged to consult their own tax advisors as to the precise tax consequences of
participation in such plan.  The granting of options will have no immediate tax
consequences on the Company or the recipient of the options, since the options
are being granted to purchase the stock at the fair market value of the stock on
the date of the grant, and since the options have no readily ascertainable fair
market value.  Upon exercise of the options, the optionee will realize and
recognize income on the excess of the fair market value of the stock on the date
of exercise over the exercise price.  The excess will be taxed at rates
applicable to ordinary income.  The Company will realize a deduction on the date
of exercise in an amount equal to the optionee's gain.

The gain, if any, received upon a subsequent disposition of the Common Stock
will constitute short-term or long-term gain to the optionee, depending on the
optionee's holding period.  In addition, the Taxpayer Relief Act of 1997 (the
"Act") made significant changes to the taxation of long-term capital gains.  In
general, the Act reduces the maximum rate of tax on the individual's net capital
gain (i.e., the excess of the net long-term capital gain for the taxable year
over the net short-term capital loss for the year) from 28% to 20%.  The rate is
reduced to 10% for net capital gains that would otherwise be taxed at 15% rate.
These rates apply for both the regular tax and the minimum tax.

For taxable years beginning after December 31, 2000, the maximum capital gains
rates for assets which are held more than five years are 8% and 18% (rather than
10% and 20%).  The 18% rate only applies to assets with holding periods that
begin after December 31, 2000.  Finally, the Act provides that the lower capital
gains rate does not apply to the sales or exchange of assets held for 18 months
or less if the sales or exchange is after July 28, 1997.  The 28% maximum rate
will continue to apply to the sales or exchange of capital assets held more than
one year but not more than 18 months.  However, the 20% maximum rate applies to
otherwise qualifying sales or exchanges occurring after May 6, 1997, and before
July 29, 1997, if the assets were held for more than one year.

The Federal income tax consequences described in this section are based on laws
and regulations in effect on April 21, 1998, and there are no assurances that
the laws and regulations will not change in the future and affect the tax
consequences of the matters discussed in this section.

No options may be exercised under the 1998 NSO Plan without compliance with
applicable securities laws.  It is contemplated by management of the Company
that the options and the shares of Common Stock called for by options granted
under the 1998 NSO Plan will be registered by the Company under the federal
securities laws during the remainder of calendar year 1998.

Options granted under the 1998 NSO Plan are nontransferable except by will or by
the laws of descent and distribution or pursuant to a qualified domestic
relations order as defined by the Code, and may be exercised during the lifetime
of the participant only by that participant or his legally authorized
representative, provided, however, the Committee, in its discretion, may allow
for transferability of such options by the participant to "Immediate Family
Members" as that term is defined under the 1998 NSO Plan.

The 1998 NSO Plan would be effective only upon shareholder approval at the 1998
Annual Meeting of Shareholders.  The affirmative vote of the holders of a
majority of the total number of shares represented and voting at the
Shareholder's Meeting, assuming a quorum is present, is required in order for
the plan to become effective.

The Board of Directors recommends that Shareholders vote "FOR" ratification of
the 1998 Nonstatutory Stock Option Plan of the Company.

PROPOSAL NO. 5:  RATIFICATION OF 1997 NONSTATUTORY STOCK OPTION GRANTS TO THE
- -----------------------------------------------------------------------------
COMPANY'S NON-EMPLOYEE DIRECTORS
- --------------------------------

The Board of Directors of the Company on an individual basis in May 1997 granted
options to purchase 10,000 shares of the Company's Common Stock to each of the
seven (7) non-employee directors (the "1997 Individual NSO Grants").

A summary of the material provisions relating to the 1997 Individual NSO Grants
is set out below.  The following summary is qualified in its entirety by
reference to the full text of the Company's Non-Qualified Stock Option Agreement
(the "Agreement") with each of the seven (7) non-employee directors, a copy of
which is attached as Exhibit C to this Proxy Statement.

                                      -11-

The purpose of the 1997 Individual NSO Grants is to encourage stock ownership by
non-employee directors of the Company, to provide an incentive for non-employee
directors to expand and improve the profits and prosperity of the Company, and
to assist the Company in retaining non-employee directors.

The non-employee directors of the Company receiving the 1997 Individual NSO
Grants were: Martin C. Bowen, Dr. H. Kirk Downey, Robert H. Johnson, John G.
Richards, Sam Rosen, R.J. Schumacher and W.C Walker.

Each non-employee director (the "Optionee") was granted nonqualified stock
options to purchase 10,000 shares of the Company's common shares at a purchase
price of $11.125 per share.  The options cannot be exercised until (i) the
passage of six months from the date of the grant, and (ii) the listing of the
underlying shares on the New York Stock Exchange.  Options to purchase 2,000
shares of the Company's Common Stock become exercisable on the day following
each annual shareholders' meeting, provided the Optionee is a non-employee
director on such date.  Unless terminated earlier pursuant to the terms of the
Agreement, the options remain exercisable for a period of ten (10) years from
the date of the grant.

Since the 1997 Individual NSO Grants are of nonstatutory stock options, the U.S.
federal income tax consequences under current federal income tax law to such
grants is the same as federal income tax consequences relating to options
granted under the 1998 Nonstatutory Stock Option Plan.  Reference is made to
information set forth under the heading Proposal No. 4:  1998 Nonstatutory
Stock Option Plan for a description of such federal income tax consequences.

No options may be exercised under the 1997 Individual NSO Grants without
compliance with applicable securities laws.  It is contemplated by management of
the Company that the options and the shares of the Company's Common Stock
underlying the options granted under the 1997 Individual NSO Grants will be
registered by the Company under the federal securities laws during the remainder
of calendar year 1998.

Options granted under the 1997 Individual NSO Grants may only by transferred
during the Optionee's lifetime (i) pursuant to a qualified domestic relations
order as defined in the Internal Revenue Code of 1986, as amended, or (ii) to an
"immediate family member" of the optionee.

The affirmative vote of the holders of a majority of the total number of shares
represented and voting at the Shareholders' Meeting, assuming a quorum is
present, is required for ratification of the 1997 Individual NSO Grants.

The Board of Directors recommends that Shareholders vote "FOR" ratification of
the 1997 Individual Nonstatutory Stock Option Grants to the Company's non-
employee directors.

                      1998 INCENTIVE STOCK OPTION PLAN OF
                            AZTEC MANUFACTURING CO.


     The 1998 Incentive Stock Option Plan (the "Plan") of Aztec Manufacturing
Co. (the "Company") is intended to advance the best interests of the Company by
providing  all full-time salaried employees  of the Company, and of any
subsidiary of the Company,  with additional incentive by increasing their
proprietary interest in the success of the Company, thereby encouraging them to
remain in the employ of the Company.  Options granted pursuant to this Plan are
intended to be "incentive stock options" within the meaning of Section 422 of
the Internal Revenue Code of 1986, as amended (the "Code").

                                   ARTICLE I

                                   Committee

     Section 1.1.  ADMINSTRATION.  The Plan shall be administered by the
Compensation Committee of the Company (the "Committee").  The Committee shall
consist of at least two (2)  Non-Employee Directors of the Company.

     Section 1.2 POWERS.  (a) Subject to the provisions of the Plan, the
Committee shall have plenary authority to determine, in its discretion, the
employees of the Company to whom Options (as hereinafter defined) shall be
granted, the number of shares to be covered by each of the Options, and the time
or times at which and the terms (not inconsistent with this Plan) under which
Options shall be granted, become exercisable and expire.  The Committee shall
also have the authority to interpret the Plan and to prescribe, amend or rescind
rules and regulations relating to it.

          (b)  The Committee shall hold meetings at such times and places as it
may determine.  Acts approved at a meeting by a majority of the members of the
Committee or acts approved in writing by the unanimous consent of the members of
the Committee shall be the valid acts of the Committee.

          (c)  No member of the Committee shall be liable for any action taken
or determination made in good faith with respect to the Plan or any Options
granted under it. No member of the Committee shall be liable for any act or
omission of any other member of the Committee or for any act or omission on his
own part, including, but not limited to, the exercise of any power and
discretion given to him under the Plan, except those resulting from his own
gross negligence or willful misconduct.

          (d)  In addition to such other rights of indemnification as he may
have as a member of the Board of Directors or the Committee, and with respect to
administration of the Plan and the granting of Options under it, each member of
the Committee shall be entitled without further act on his part to indemnity
from the Company for all expenses (including the amount of any judgments and the
amount of approved settlements made with a view to the curtailment of costs of
litigation, other than amounts paid to the Company itself) reasonably incurred
by him in connection with or arising out of any action, suit or proceeding with
respect to the administration of the Plan or the granting of Options under it in
which he may be involved by reason of his being or having been a member of the
Committee, whether or not he continues to be a member of the Committee at the
time of the incurring of such expenses; provided, however, that such indemnity
shall not include any expenses incurred by a member of the Committee (i) in
respect to matters as to which he shall be finally adjudged in such action, suit
or proceeding to have been guilty of gross negligence or willful misconduct in
the performance of his duties as a member of the Committee; or (ii) in respect
of any matter in which any settlement is effected for an amount in excess of the
amount approved by the Company on the advice of its legal counsel; and provided
further that no right of indemnification under the provisions set forth herein
shall be available to or accessible by any such member of the Committee unless
within five (5) days after institution of any such action, suit or proceeding he
shall have offered the Company in writing the opportunity to handle and defend
such action, suit or proceeding at its own expense. The foregoing right of
indemnification shall inure to the benefit of the heirs, executors or
administrators of each such member of the Committee and shall be in addition to
all other rights to which such member of the Committee would be entitled as a
matter of law, contract or otherwise.

                                 Participants

     Section 2.1.  ELIGIBILITY.  The persons who shall be eligible to receive
Options shall be all full-time salaried employees of the Company.   For the
purposes of this Plan, the term "Employee(s)" shall mean employee(s) of the
Company, or any of its subsidiaries or affiliates, that adopt the Plan and shall
not include members of the Board who are not employed by the Company.  The
Committee shall select the eligible individuals to whom Options shall be granted
("Participants"), and shall determine the number of Options to be granted.  In
making this determination, the Committee shall weigh the positions and
responsibilities of the individuals being considered, the nature of their
services, their present and potential contributions to the success of the
Company and such other factors as the Committee shall deem relevant to
accomplish the purposes of the Plan.

     Section 2.2.  NUMBER OF OPTIONS.  An eligible employee may be a Participant
under more than one Option Agreement.  As used herein, the term "Option" shall
mean the option to purchase one share of Common Stock (as hereinafter defined)
in accordance with the Plan.  The term "Option Agreement" shall mean the
agreement under which Options are granted.

     Section 2.3.  NO RIGHTS AS SHAREHOLDER.  No Participant shall have any
rights as a shareholder with respect to shares covered by Options granted to him
pursuant to the Plan (including the right to vote the shares or to receive any
dividends declared thereon) until the date of issuance of a stock certificate
for such shares, notwithstanding the exercise of the Options covering such
shares.

     Section 2.4.  ELIGIBILITY FOR OTHER PLANS.  Participation in the Plan shall
not affect eligibility for any profit-sharing, bonus, insurance, pension, stock
option, or other compensation plan which the Company currently has in effect or
may at any time in the future adopt for employees.

     Section 2.5.  EMPLOYMENT OBLIGATION.  The granting of an Option shall not
impose any obligation upon the Company to employ or continue to employ any
Participant, and the right of the  Company to terminate the employment of any
Participant shall not be diminished or affected by reason of the fact that
Options have been granted to him.

     Section 2.6.  CONTINUOUS EMPLOYMENT.  An Option granted under this Plan
will terminate in accordance with Section 4.8 below upon the termination of
employment of a Participant.  However, the requisite employment relationship
with respect to Options granted hereunder will be treated as continuing intact
while the Participant (with the prior approval of the Committee) is on military
leave, sick leave, or other bona fide leave of absence (such as temporary
employment by the Government) if the period of such leave does not exceed ninety
(90) days, or, if longer, so long as the Participant's right to reemployment is
guaranteed by statute or by contract.

     Section 2.7.  SHAREHOLDER APPROVAL.  No Option may be exercised under the
Plan until the Plan has been approved by the affirmative vote of a majority of
the total number of shares represented and entitled to vote thereon at a meeting
of the shareholders, assuming a quorum is present.  Such approval must be
obtained from the shareholders of the Company within twelve (12) months from the
prior approval, if any, of the Plan by the Board of Directors.

     Section 2.8.  NO OBLIGATION TO EXERCISE OPTION.  The granting of an Option
under the Plan shall not impose any obligation upon the Participant to exercise
the Option.  A Participant may, at any time, elect in writing to abandon Options
granted under the Plan.

                                  ARTICLE III

                           SHARES SUBJECT TO OPTIONS

     Section 3.1.  SHARES AVAILABLE.  The shares of stock subject to Options
shall be the Company's One Dollar ($1.00) par value common stock (the "Common
Stock").  The aggregate number of shares of Common Stock for which Options may
be granted under the Plan shall not exceed 750,000 shares of Common Stock.  Such
shares may be treasury or authorized but unissued shares of Common Stock of the
Company.

                                      -16-

<PAGE>
 
     Section 3.2.  ALLOTMENT OF OPTIONS FOR THE PURCHASE OF SHARES.  (a) Subject
to the allotment requirements of Section 3.2(b), the Committee shall determine
the number of Options for the purchase of shares of Common Stock to be granted
from time to time to any employee eligible to become a Participant.

          (b)   The aggregate fair market value (determined at the time the
Option is granted) of shares of Common Stock underlying Options exercisable by a
Participant under the Plan for the first time during any calendar year under the
Plan (or any other incentive stock option plan of the Company or a parent or
subsidiary corporation of the Company, as those terms are defined in Section
424(e) and (f), respectively, of the Code) shall not exceed $100,000.

     Section 3.3.  SHARES FROM UNEXERCISED OPTIONS.  In the event that any
outstanding Options under the Plan for any reason expire or are terminated, the
shares of Common Stock allocable to the unexercised Options may again be
subjected to other Option Agreements under the Plan.

                                  ARTICLE IV

                        TERMS AND CONDITIONS OF OPTIONS

     Options granted pursuant to the Plan shall be evidenced by Option
Agreements in such form as the Committee shall, from time to time, recommend,
which (although they need not be identical in form) shall be subject to the
following terms and conditions:

     Section 4.1.  OPTION PRICE.  The price at which shares of Common Stock may
be purchased pursuant to Options granted under the Plan (the "Option Price")
shall be no less than one hundred percent (100%) of the fair market value of the
shares of Common Stock on the date the Option is granted.

     Section 4.2.  TIME OF GRANTING OPTIONS.  Neither anything contained in the
Plan or in any resolution adopted or to be adopted by the Board of Directors of
the Company or the shareholders of the Company nor any action taken by the
Committee shall constitute the granting of Options.  The granting of Options
shall take place only when the written Option Agreement has been duly executed
by or on behalf of the Company and the Participant to whom such Options shall be
granted.  Notwithstanding anything herein to the contrary, no Options shall be
granted under the Plan more than ten years after the effective date of the Plan.

     Section 4.3  DURATION OF OPTIONS.  No Options shall be exercisable after
the expiration of ten (10) years from the date such Options are granted and the
Committee in its discretion, subject to the provisions of Section 4.4 with
regard to holders of 10% or more of the Common Stock, may provide that Options
shall be exercisable during such ten (10) year period or any lesser period of
time.

     Section 4.4.  TEN PERCENT (10%) SHAREHOLDERS.  Anything herein to the
contrary notwithstanding, Options granted by the Committee to any eligible
employee who at the time of the grant of the Options owns, directly or
indirectly, more than ten percent (10%) of the total combined voting power of
all classes of stock of the Company, or of any parent or subsidiary corporation
of the Company, shall be exercisable at an Option Price which is at least one
hundred ten percent (110%) of the fair market value of the shares of Common
Stock determined at the time such Options are granted and such Options shall not
be exercisable after the expiration of five (5) years from the date they are
granted.  The attribution rules of Section 424(d) of the Code shall apply in the
determination of indirect ownership of stock of the Company, and of any parent
or subsidiary corporation of the Company.

     Section 4.5.  AMOUNT EXERCISABLE.  Options may be exercised in blocks of no
less than one hundred (100) at any one time, unless the number exercised is the
total number exercisable by a Participant in which case all, but not less than
all, Options may be exercised.

     Section 4.6.  METHOD OF EXERCISE.  (a) No Option shall be deemed to have
been exercised prior to the receipt by the Company of written notice of such
exercise and of payment in full of the Option Price for the shares to be
purchased.  Each such notice shall specify the number of shares to be purchased
and shall (unless the shares are covered by a then current registration
statement under the Securities Act of 1933 (the "Act")), contain the
Participant's acknowledgment in form and substance satisfactory to the Company
that (i) such shares are being purchased for investment and not for distribution
or resale (other than a distribution or resale which, in the opinion of counsel
satisfactory to the Company, may be made without violating the registration
provisions of the Act), (ii) the Participant 

                                      -17-

<PAGE>
 
has been advised and understands (A) the shares have not been registered under
the Act and are "restricted securities" within the meaning of Rule 144 under the
Act and are subject to restrictions on transfer, and (B) the Company is under no
obligation to register the shares under the Act or to take any action which
would make available to the Participant any exemption from such registration,
and (iii) such shares may not be transferred without compliance with all
applicable federal and state securities laws. Notwithstanding the above, should
the Company be advised by counsel that issuance of shares should be delayed
pending (i) registration under federal or state securities laws, or (ii) the
receipt or an opinion that an appropriate exemption therefrom is available, the
Company may defer issuance of shares underlying any Options granted hereunder
until either such event has occurred. No Participant who is subject to Section
16 of the Securities Exchange Act of 1934 may sell an Option or any share
acquired by exercise of an Option for at least six (6) months after the date the
Option was granted. No Participant shall have any rights as a shareholder with
respect to shares underlying Options until the date of issuance of a stock
certificate for such shares.

          (b)  A Participant shall pay for shares acquired upon the exercise of
Options (i) in cash, (ii) by check payable to the order of the Company, or (iii)
by a combination of the foregoing.  Alternatively, payment may be made all or in
part in shares of the Common Stock held by the Participant for more than one
year.  If payment is made in whole or in part in shares of the Common Stock,
then the Participant shall deliver to the Company certificates registered in the
name of such Participant representing shares of Common Stock legally and
beneficially owned by such Participant, free of all liens, claims and
encumbrances of every kind, accompanied by stock powers duly endorsed in blank
by the record holder of the shares represented by such certificates.

          (c)  The certificate or certificates for shares of Common Stock as to
which Options are exercised shall be registered in the name of the person or
persons exercising the Options.  In the event the Options shall be exercised
pursuant to Section 4.8(b) by any person or persons other than the Participant,
the notice shall be accompanied by appropriate proof of the right of such person
or persons to exercise the Options.

          (d)  The Company shall deliver to the Participant the certificate or
certificates for the number of shares of Common Stock with respect to which the
Options have been exercised to the address which shall be specified in the
notice of exercise required by Section 4.6(a), and delivery shall be deemed
effected for all purposes when the Company or its transfer agent shall have
deposited such certificate or certificates in the United States mail addressed
to the Participant at such address.

     Section 4.7.  NON-TRANSFERABILITY OF OPTIONS.  Options shall not be
transferable by the Participant other than by will or under the laws of dscent
and distribution and shall be exercisable, during his lifetime, only by him.

     Section 4.8.  SEVERANCE OF EMPLOYMENT.  (a) Except as otherwise provided in
Section 4.8(b), in the event of the termination of employment of the Participant
by the Company for any reason whatsoever other than the gross and willful
misconduct of the Participant or death or disability, whether by his own
volition or otherwise, any Options granted to the Participant under the Plan
shall terminate on the earlier of the date of their expiration or the day which
is three (3) months after the date of termination of employment of the
Participant.  After the date of termination of employment of the Participant,
but prior to the date of termination of such Options, as provided in the
immediately preceding sentence, the Participant shall have the right to exercise
the Options which were exercisable on the date of the termination of the
Participant's employment with the Company.  In the event of termination of
Participant's employment with the Company because of gross and willful
misconduct, including but not limited to wrongful appropriation of funds of the
Company or the commission of a felony, Options granted to Participant, to the
extent not previously exercised, shall terminate.

          (b)  In the event of the death or total disability of the Participant
while in the employ of the Company, any Options granted to a Participant under
the Plan shall terminate on the earlier of (i) the date of their expiration or
(ii) in the event of the death of the Participant, the day which is twelve (12)
months after the date of death of the Participant or in the event of the total
disability of the Participant, the day which is twelve (12) months after the
date of termination of employment of the Participant, as the case may be.  After
the date of death or total disability of the Participant, as the case may be,
but prior to the date of termination of Options provided in the immediately
preceding sentence, the Participant's executors, administrators or any person or
persons to whom the Options may be transferred by will or by the laws of descent
and distribution (in the event of the Participant's death) or the Participant
(in the event of the Participant's total disability) shall have the right at any
time during the period of time specified in this Section 4.8(b) to exercise the
Options, in whole or in part regardless of whether or not such Options were
exercisable on the date of death or total disability.  For purposes of this
Section 4.8(b), the term "total disability" shall mean the inability of the
Participant to return to the handling of substantially all of his duties as a
full-time salaried 

                                      -18-

<PAGE>
 
employee of the Company within ninety (90) days after injury or illness. The
Committee shall determine whether or not a Participant is totally diabled and
such determination by the Committee shall be binding on the Participant.

     Section 4.9.  REQUIREMENTS OF REGULATORY AGENCIES.  The Company shall not
be required to sell or issue any shares of Common Stock under any Options if the
issuance of such shares of Common Stock shall constitute a violation by the
Participant or the Company of any provisions of any law or regulation of any
governmental authority.

of the Company may modify, revise or terminate the Plan at any time and from
time to time; provided, however, that without the further approval of the
shareholders of the Company, the Board of Directors may not (i) materially
increase the benefits accruing to Participants under the Plan; (ii) materially
increase the number of securities which may be issued under the Plan; (iii)
materially modify the requirements as to eligibility for participation in the
Plan; or (iv) change any provisions of the Plan which would affect the income
tax status of the Options granted hereunder.  No modification of this Plan
shall, without the consent of the Participant, alter or impair any rights or
obligations of such Participant under any Options theretofore granted under the
Plan except for such modifications as, in the opinion of counsel for the
Company, may be necessary or appropriate from time to time to enable the Options
granted pursuant to the Plan to comply with the requirements of any governmental
or regulatory agency.

     Section 5.2.  ADJUSTMENTS.  Adjustments shall be made to the number of
Options and the per share exercise price therefor as provided in this section:

          (a)  In the event that the outstanding shares of Stock of the Company
are hereafter increased or decreased or changed into or exchanged for a
different number or kind of shares or other securities of the Company or of
another corporation, by reason of a recapitalization, reclassification, stock
split-up, combination of shares, dividend or other distribution payable in
capital stock, appropriate adjustment shall be made by the Committee in the
number and kind of shares for the purchase of which Options may be granted under
the Plan.  In addition, the Committee shall make appropriate adjustment in the
number and kind of shares as to which outstanding Options, or portions thereof
then unexercised, shall be exercisable, to the end that the proportionate
interest of the holder of the Option shall, to the extent practicable, be
maintained as before the occurrence of such event.  Such adjustment in
outstanding Options shall be made without change in the total price applicable
to the unexercised Options but with a corresponding adjustment in the Option
Price per share.

          (b)  In the event of the dissolution of the Company, any Options
granted and outstanding under the Plan shall terminate as of the effective date
of dissolution.

          (c)  In the event of a Reorganization (as hereinafter defined) in
which the Company is not the surviving or acquiring company, or in which the
Company is or becomes a wholly-owned subsidiary of another company after the
effective date of the Reorganization, then

               (1)  If there is no plan or agreement respecting the
     Reorganization ("Reorganization Agreement") or if the Reorganization
     Agreement does not specifically provide for the change, conversion or
     exchange of the shares under outstanding and unexercised Options for
     securities of another corporation, any such Options shall be deemed
     exercisable for stock of the surviving corporation or parent corporation of
     which the Company becomes a subsidiary at a rate of exchange to be
     determined by the Committee, but in no event shall the fair market value of
     the stock substituted by the Common Stock of the Company at any time of the
     Reorganization be less than the fair market value of the Common Stock of
     the Company at the time of the Reorganization; or

               (2)  If there is a Reorganization Agreement and if the
     Reorganization Agreement specifically provides for the change, conversion
     or exchange of the shares under outstanding and unexercised Options for
     securities of another corporation, then the Committee shall adjust the
     shares under such outstanding and unexercised Options (and shall adjust the
     shares remaining under the Plan which are then available to be optioned
     under the Plan, if the Reorganization Agreement makes specific provision
     therefor) in 

                                      -19-

<PAGE>
 
     a manner not inconsistent with the provisions of the Reorganization
     Agreement for the adjustment, change, conversion or exchange of such stock
     and such Options.

          (d)  The term "Reorganization" as used in paragraph (c) of this
Section 5.2 shall mean any statutory merger, statutory consolidation, sale of
all or substantially all of the assets of the Company, or sale, pursuant to an
agreement with the Company, of securities of the Company pursuant to which the
Company is or becomes a subsidiary of another company after the effective date
of the Reorganization.

          (e)  Adjustments and determinations under this Section 5.2 shall be
made by the Committee, whose decisions as to what adjustments or determinations
shall be made, and the extent thereof, shall be final, binding and conclusive.
No fractional shares of Common Stock shall be issued in connection with the
exercise of any Options and any fractional shares of Common Stock resulting from
the computations pursuant to this Section 5.2 shall be eliminated from the
respective Option.

          1.  The Plan shall be administered by the Committee.  The Committee
     shall hold meetings at such times and places as it may determine.  Acts
     approved at a meeting by a majority of the members of the Committee or acts

          4.  In addition to such other rights of indemnification as he may have

     itself) reasonably incurred by him in connection with or arising out of any
     action, suit or proceeding with respect to the administration of the Plan
     or the granting of Options under it in which he may be involved by reason
     of his being or having been a member of the Committee, whether or not he
     continues to be such member of the Committee at the time of the incurring
     of such expenses; provided, however, that such indemnity shall not include
     any expenses incurred by such member of the Committee (i) in respect of
     matters as to which he shall be finally adjudged in such action, suit or
     proceeding to have been guilty of gross negligence or willful misconduct in
     the performance of his duties as a member of the Committee; or (ii) in

nonemployee directors of the Company and only such persons shall be eligible to
receive Options under this Plan.

F.   Option Price.
     ------------ 

     The purchase price for Common Stock under each Option shall be one hundred
percent (100%) of the fair market value of the Common Stock at the time the
Option is granted, but in no event less than the par value of the Common Stock.

G.   Terms and Conditions of Options.
     ------------------------------- 

     Options granted pursuant to the Plan shall be evidenced by written Option
Agreements in such form as the Committee shall from time to time approve, which
Option Agreements shall comply with and be subject to the following terms and
conditions:

          1.  Grant of Options.  Neither anything contained in the Plan nor any
     resolution adopted or to be adopted by the Board of Directors of the
     Company or the shareholders of the Company nor any action taken by the
     Committee shall constitute the granting of Options.  The granting of
     Options shall take place only when 

                                      -23-

<PAGE>
 
     the written Option Agreement has been duly executed by or on behalf of the
     Company and the Participant to whom such Options shall be granted. The Plan
     is subject to the approval of the Company's shareholders and no Options
     shall be granted under it until and unless such approval is received.

          2.  Duration of Options.    Subject to the provisions of Section H
     below, Options shall become exercisable and shall be exercisable for such
     period as is determined by the Committee.

          3.  Exercise and Payment.  No Option shall be deemed to have been
     exercised prior to the receipt by the Company of written notice of such
     exercise and of payment in full of the Option Price for the Options to be
     exercised.  Each such notice shall specify the number of Options to be
     exercised and shall (unless the shares underlying the Options are covered
     by a then current registration statement under the Securities Act of 1933
     (the "Act")), contain the Participant's acknowledgment in form and
     substance satisfactory to the Company that (i) such shares are being
     purchased for investment and not for distribution or resale (other than a
     distribution or resale which, in the opinion of counsel satisfactory to the
     Company, may be made without violating the registration provisions of the
     Act), (ii) the Participant has been advised and understands that (A) the
     shares have not been registered under the Act and are "restricted
     securities" within the meaning of Rule 144 under the Act and are subject to
     restrictions on transfer, and (B) the Company is under no obligation to
     register the shares under the Act or to take any action which would make
     available to the Participant any exemption from such registration, and
     (iii) such shares may not be transferred without compliance with all
     applicable federal and state securities laws.  Notwithstanding the above,
     should the Company be advised by counsel that issuance of shares should be
     delayed pending (i) registration under federal or state securities laws, or
     (ii) the receipt of an opinion that an appropriate exemption therefrom is
     available, the Company may defer issuance of any shares hereunder until
     either such event has occurred.  No Participant who is subject to Section
     16 of the Securities Exchange Act of 1934 may sell an Option or any share
     acquired upon the exercise of an Option for at least six (6) months after
     the date of grant of the Option.  No Participant shall have any rights as a
     shareholder with respect to any share acquired upon the exercise of an
     Option until the date of issuance of a stock certificate for such shares.
     The Option Price shall be paid in full at the time an Option is exercised
     under the Plan.  Otherwise, an exercise of any Option granted under the
     Plan shall be invalid and of no effect.  Promptly after the exercise of an
     Option and the payment of the full Option Price, the Participant shall be
     entitled to the issuance of a stock certificate evidencing his ownership of
     such Common Stock.

          4.  Medium of Payment.  A Participant shall pay for shares acquired
     upon the exercise of Options (i) in cash, (ii) by check payable to the
     order of the Company, or (iii) by a combination of the foregoing.
     Alternatively, payment may be made all or in part in shares of the Common
     Stock held by the Participant for more than one year.  If payment is made
     in whole or in part in shares of Common Stock, then the Participant shall
     deliver to the Company certificates registered in the name of such
     Participant representing shares of Common Stock legally and beneficially
     owned by such Participant free of all liens, claims and encumbrances of
     every kind, accompanied by stock powers duly endorsed in blank by the
     record holder of the shares represented by such certificates.

H.   Termination of Options.
     ---------------------- 

     No Options shall be exercisable after the first to occur of the following:

          1.  Expiration of the Option term specified in the Option Agreement,
     which shall not exceed ten (10) years from the date the Options first
     become exercisable;

          2.  Expiration of three (3) months from the date the Participant's
     service as  an executive officer or nonemployee director with the Company
     terminates for any reason other than the circumstances described in 3, 4 or
     5 below;

          3.  Expiration of one (1) year from the date the Participant's service
     as  an executive officer or nonemployee director with the Company
     terminates by reason of the Participant's disability (within the meaning of
     section 22(e)(3) of the Code) or death;

          4.  Expiration of ten (10) days (which period may be extended on a
     case by case basis in the sole discretion of the Committee) from the date
     the Participant voluntarily resigns as  an executive officer or 

                                      -24-

<PAGE>
 
     nonemployee director of the Company (not including any termination due to
     the death or disability of the Participant); or

          5.  A finding by the Committee, after full consideration of the facts
     presented on behalf of both the Company and the Participant, that a
     Participant has been removed as  an executive officer or nonemployee
     director of the Company for Cause.  For purposes of this paragraph "Cause"
     shall mean: (A) a pattern of gross negligence or an act of willful
     misconduct by Participant in the performance of his duties to the Company
     which has a material adverse effect on the Company's reputation, business,
     properties or business relationships, or (B) Participant's conviction of a
     felony or misdemeanor (other than a traffic violation) or of
     misappropriation of funds of the Company, or (C) Participant's
     appropriation to himself of a corporate opportunity of the Company which
     Participant fails to make available to the Company.  In the event of a
     finding that participant has been removed for Cause, in addition to
     immediate termination of the Option, the Participant shall automatically
     forfeit all shares to be acquired upon the exercise of Options for which
     the Company has not yet delivered the share certificates upon refund by the
     Company of the Option Price.

          Notwithstanding the foregoing, any Participant who is elected as a
     director or advisory director before or contemporaneously with his
     voluntary termination as an employee or director of the Company (regardless
     of the position for which the Options were awarded) shall not be deemed to
     have a break in service that would trigger the termination provisions of
     paragraph 4 of this Section H.  In this circumstance, the provisions of
     paragraphs 1, 2, 3 and 5 of this Section H remain applicable.

I.   Adjustments in Common Stock.
     --------------------------- 

     Adjustments shall be made with reference to the number of shares of Common
Stock underlying Options and the per share exercise price therefor as provided
in this section:

          1.  In the event that the outstanding shares of Common Stock of the
     Company are hereafter increased or decreased or changed into or exchanged
     for a different number or kind of shares or other securities of the Company
     or of another corporation, by reason of a recapitalization,
     reclassification, stock split-up, combination of shares, dividend or other
     distribution payable in capital stock, appropriate adjustment shall be made
     by the Committee in the number and kind of shares for the purchase of which
     Options may be granted under the Plan.  In addition, the Committee shall
     make appropriate adjustment in the number and kind of shares as to which
     outstanding Options shall be exercisable, to the end that the proportionate
     interest of the holder of the Options shall, to the extent practicable, be
     maintained as before the occurrence of such event.  Such adjustment in
     outstanding Options shall be made without change in the total price
     applicable to the unexercised Options but with a corresponding adjustment
     in the Option Price per share.

          2.  In the event of a Reorganization (as hereinafter defined) in which
     the Company is not the surviving or acquiring company, or in which the
     Company is or becomes a wholly-owned subsidiary of another company after
     the effective date of the Reorganization, then

              a.  If there is no plan or agreement respecting the Reorganization
          ("Reorganization Agreement") or if the Reorganization Agreement does
          not specifically provide for the change, conversion or exchange of the
          shares under outstanding and unexercised stock options for securities
          of another corporation, any such stock options shall be deemed
          exercisable for stock of the surviving corporation or parent
          corporation of which the Company becomes a subsidiary at a rate of
          exchange to be determined by the Committee, but in no event shall the
          fair market value of the stock substituted for the stock of the
          Company at the time of the Reorganization be less than the fair market
          value of the stock of the Company at the time of the Reorganization.

              b.  If there is a Reorganization Agreement and if the
          Reorganization Agreement specifically provides for the change,
          conversion or exchange of the shares under outstanding and unexercised
          stock options for securities of another corporation, then the
          Committee shall adjust the shares under such outstanding and
          unexercised stock options (and shall adjust the shares remaining under
          the Plan which are then available to be optioned under the Plan, if
          the Reorganization Agreement makes specific provision therefor) in a
          manner not inconsistent with the provisions of the Reorganization
          Agreement for the adjustment, change, conversion or exchange of such
          stock and such Options.

                                      -25-

<PAGE>
 
              c.  The term "Reorganization" as used in paragraph 2 of this
          Section I shall mean any statutory merger, statutory consolidation,
          sale of all or substantially all of the assets of the Company, or
          sale, pursuant to an agreement with the Company, of securities of the
          Company pursuant to which the Company is or becomes a subsidiary of
          another company after the effective date of the Reorganization.

              d.  Adjustments and determinations under this Section I shall be
          made by the Committee, whose decisions as to what adjustments or
          determinations shall be made, and the extent thereof, shall be final,
          binding and conclusive.

J.   Amendment of the Plan.
     --------------------- 

     Except as hereinafter limited, the Board of Directors of the Company may
modify, revise or terminate the Plan at any time and from time to time;
provided, however, that without the further approval of the shareholders of the
Company, the Board of Directors may not (i) materially increase the benefits
accruing to Participants under the Plan; (ii) materially increase the number of
securities which may be issued under the Plan; (iii) materially modify the
requirements as to eligibility for participation in the Plan; or (iv) change any
provisions of the Plan which would affect the income tax status of the Options
granted hereunder.   No modification of this Plan shall, without the consent of
the Participant, alter or impair any rights or obligations of such Participant
under any Options theretofore granted under the Plan except for such
modifications as, in the opinion of counsel for the Company, may be necessary or
appropriate from time to time to enable the Options granted pursuant to the Plan
to comply with the requirements of any governmental or regulatory agency.

K.   Miscellaneous.
     ------------- 

     1.   No fractional shares shall be issued under this Plan.

          2.  Options may be exercised only in blocks of 100 unless the number
     exercised is the total number exercisable by a Participant in which case
     all, but not less than all, exercisable Options may be exercised.

          3.  The granting of Options shall impose no obligation upon the
     Participant to exercise such Options.

          4.  Options shall not be transferable other than by will or by the
     laws of descent and distribution or pursuant to a qualified domestic
     relations order as defined by the Code, and may be exercised during the
     lifetime of a Participant only by that Participant or by his legally
     authorized representative; provided, however, that the Committee, in its
     discretion, may allow for transferability of such Options by the
     Participant to "Immediate Family Members".

          5.  The Company, during the term of this Plan, will at all times
     reserve and keep available the number of shares of Common Stock sufficient
     to satisfy the requirements of this Plan.

                            AZTEC MANUFACTURING CO.
                   1997 NONSTATUTORY STOCK OPTION AGREEMENT


     This agreement granting an option to purchase shares of the One Dollar
($1.00) par value common stock of AZTEC MANUFACTURING CO. (the "Stock") is made
as of May 20, 1997, between AZTEC MANUFACTURING CO. (the "Company") and
________________________ (the "Optionee"), a Director (as hereinafter defined)
of the Company, pursuant resolutions (the "Resolutions"), adopted by the
Directors of the Company on May 20, 1997 (the "Date of Grant").

     Now, therefore, in consideration of the Company's desire to further its
interests and Optionee's desire to increase his proprietary interest in the
Company, it is agreed by and between the parties as follows:

1.   Grant of Options.  Optionee is hereby granted options (the "Option" or
"Options") to purchase Ten Thousand (10,000) shares (the "Option Shares") of
Stock at the purchase price of Eleven and One-eight Dollars ($11.125) per Option
Share (the "Option Price").  Options granted herein to purchase Two Thousand
(2000) shares of Stock shall become exercisable on the day following each annual
shareholders meeting commencing with the Company's 1997 annual shareholders
meeting provided Optionee is a Director of the Company on such date and,
provided further, that no option shall be exercised until (i) the passage of six
months from the Date of Grant, and (ii) the listing of the underlying shares on
the New York Stock Exchange.

2.   Period During Which Options Are Exercisable.  The Option shall become
exercisable as provided in Paragraph 1. above and, unless terminated earlier as
provided below shall remain exercisable for a period of ten (10) years from the
Date of Grant.

3.   Method of Exercise and Payment. Options granted hereby may be exercised and
shall be paid for as provided below:

     (a)  Method of Exercise.  An Option may be exercised to the extent it is
exercisable under Section 1 above by written notice addressed to the Company's
President at the Company's principal executive office specifying the number of
Option Shares to be purchased and, unless the Option Shares are covered by a
then-current registration statement under the Securities Act of 1933 (the
"Act"), containing the Optionee's acknowledgment, in form and substance
satisfactory to the Company, that the Optionee:

          (i)   is purchasing such Option Shares for investment and not for
distribution or resale (other than a distribution or resale which, in the
opinion of counsel satisfactory to the Company, may be made without violating
the registration provisions of the Act);

          (ii)  has been advised and understands that:

                (A)  the Option Shares have not been registered under the Act
and are "restricted securities" within the meaning of Rule 144 under the act and
are subject to restrictions on transfer; and

                (B)  the Company is under no obligation to register the Option
Shares under the Act or to take any action which would make available to the
Optionee any exemption from such registration; and

          (iii) has been advised and understands that such Option Shares may
not be transferred without compliance with all applicable federal and state
securities laws.

The notice shall be accompanied by payment of the aggregate price of the Option
Shares being purchased.  Such exercise shall be effective upon the actual
receipt by the Company's President of such written notice and payment.  Such
notice must be given by Optionee, or his or her guardian or other legal
representative, unless the Option is 

                                      -28-

<PAGE>
 
exercised after Optionee's death, in which case it may be given by Optionee's
executor, administrator or other legal representative.

     (b)  Medium of Payment.  An Optionee shall pay for Option Shares (i) in
cash, (ii) by check payable to the order of the Company, or (iii) by a
combination of the foregoing.  Alternatively, payment may be made all or in part
in shares of the Common Stock held by the Optionee for more than one year.  If
payment is made in whole or in part in shares of the Common Stock, then the
Optionee shall deliver to the Company certificates registered in the name of
such Optionee representing shares of Common Stock legally and beneficially owned
by such Optionee, free of all liens, claims and encumbrances of every kind,
accompanied by stock powers duly endorsed in blank by the record holder of the
shares represented by such certificates.

4.   Termination of the Option.  No Options shall be exercisable after the first
to occur of the following:

          (i)   The expiration of the Option term specified herein;

          (ii)  The date, if any, set by the Board of Directors of the Company
(the "Board of Directors") to be an accelerated expiration date in the event of
dissolution or liquidation of the Company or consummation of any corporate
combination transaction in which the Company is not the surviving or acquiring
company or in which the Company becomes a wholly-owned subsidiary of another
company, provided an Optionee who holds an Option is given written notice at
least thirty (30) days before the date so fixed;

          (iii) Expiration of three (3) months from the date the Optionee's
service as a Director of the Company terminates for any reason other than the
circumstances described by subparagraphs (iv), (v) or (vi) below;

          (iv)  Expiration of one (1) year from the date the Optionee's service
as Director of the Company terminates by reason of the Optionee's disability
(within the meaning of section 22(e)(3) of the Internal Revenue Code of 1986, as
amended) or death;

          (v)   Expiration of ten (10) days (which period may be extended on a
case by case basis in the sole discretion of the Board of Directors) from the
date the Optionee voluntarily resigns as a Director of the Company (not
including any termination due to the death or disability of the Optionee); or

          (vi)  A finding by the Board of Directors (without participation by
the Director in question) after full consideration of the facts presented on
behalf of both the Company and the Optionee, that an Optionee has been removed
as a Director of the Company for Cause. For purposes of this paragraph "Cause"
shall mean: (A) a pattern of gross negligence or an act of willful misconduct by
Optionee in the performance of his duties to the Company which has a material
adverse effect on the Company's reputation, business, properties or business
relationships, or (B) Optionee's conviction of a felony or misdemeanor (other
than a traffic violation) or of misappropriation of funds of the Company, or (C)
Optionee's appropriation to himself of a corporate opportunity of the Company
which Optionee fails to make available to the Company. In the event of a finding
that Optionee has been discharged for Cause, in addition to immediate
termination of the Option, the Optionee shall automatically forfeit all Option
Shares for which the Company has not yet delivered the share certificates upon
refund by the Company of the Option Price.

5.   Adjustments in Stock.   Adjustments shall be made with reference to the
number of Option Shares and the per share exercise price therefor as provided in
this section:

     (a) In the event that the outstanding shares of Stock are hereafter
increased or decreased or changed into or exchanged for a different number or
kind of shares or other securities of the Company by reason of a
recapitalization, reclassification, stock split-up, combination of shares,
dividend or other distribution payable in capital stock, appropriate adjustment
shall be made by the Board of Directors in the number and kind of shares as to
which this Option shall be exercisable, to the end that the proportionate
interest of the holder of this Option shall, to the extent practicable, be
maintained as before the occurrence of such event.  Such adjustment in this
Option shall 

                                      -29-

<PAGE>
 
be made without change in the total price applicable to the unexercised Option
but with a corresponding adjustment in the option price per share.

     (b)  In the event of a Reorganization (as hereinafter defined) in which the
Company is not the surviving or acquiring company, or in which the Company is or
becomes a wholly-owned subsidiary of another company after the effective date of
the Reorganization, then

          (i)   If there is no plan or agreement respecting the Reorganization
("Reorganization Agreement") or if the Reorganization Agreement does not
specifically provide for the change, conversion or exchange of the shares under
outstanding and unexercised stock options for securities of another corporation,
the unexercised portion of this Option shall be deemed exercisable for stock of
the surviving corporation or parent corporation of which the Company becomes a
subsidiary at a rate of exchange to be determined by the Board of Directors, but
in no event shall the fair market value of the stock substituted for the stock
of the Company at the time of the Reorganization be less than the fair market
value of the stock of the Company at the time of the Reorganization.

          (ii)  If there is a Reorganization Agreement and if the Reorganization
Agreement specifically provides for the change, conversion or exchange of the
shares under outstanding and unexercised stock options for securities of another
corporation, then the Board of Directors shall adjust the shares under the
unexercised portion of this Option in a manner not inconsistent with the
provisions of the Reorganization Agreement for the adjustment, change,
conversion or exchange of such stock and this Option.

          (iii) The term "Reorganization" as used in paragraph (b) of this
Section 5 shall mean any statutory merger, statutory consolidation, sale of all
or substantially all of the assets of the Company, or sale, pursuant to an
agreement with the Company, of securities of the Company pursuant to which the
Company is or becomes a subsidiary of another company after the effective date
of the Reorganization.

          (iv)  Adjustments and determinations under this Section 5 shall be
made by the Board of Directors, whose decisions as to what adjustments or
determinations shall be made, and the extent thereof, shall be final, binding
and conclusive.

6.   Transferability; Rights Prior to Exercise of Option.  In the event of
death, this Option may be exercised by Optionee's executor, administrator or
other legal representative. During Optionee's lifetime, this Option may not be
sold, pledged, assigned or transferred in any manner other than (i) pursuant to
a qualified domestic relations order as defined in the Internal Revenue Code of
1986, as amended, or (ii) to an Immediate Family Member of the Optionee. The
term "Immediate Family Member", as used in this Agreement, shall mean the
children, grandchildren, siblings or parents of the Optionee, or bona fide
trusts, partnerships or other entities controlled by, and of which the
beneficiaries are, Immediate Family Members of the Optionee. Any Option grants
that are transferable are further conditioned on the Optionee and the Immediate
Family Members agreeing to abide by the Company's then current stock option
transfer guidelines. No holder of this Option shall have any rights as a
shareholder with respect to the Option Shares until payment of the Option Price
and delivery to Optionee or a permitted transferee of the certificates for such
shares as herein provided.

7.   Definition of the Term "Director".  The term "Director" as used in this
Agreement shall mean a non-employee member of the Board of Directors.  A former
member of the Board of Directors who is named an advisory or emeritus member of
the Board of Directors shall be deemed to retain his status as a Director for
purposes of this Agreement so long as he continues to serve in the capacity of
an Advisory or Emeritus Director.  The word "Director" shall have the meaning
set forth in this definition regardless of whether or not the first letter of
the word is capitalized.

8.   Binding Effect.  This Agreement shall inure to the benefit of and be
binding upon the parties hereto and their respective heirs, executors,
administrators, other legal representative, successors and permitted assigns.

     IN WITNESS WHEREOF the parties hereto have caused this Agreement to be
executed as of the date first set forth above.
